Nonsteroidal Anti Inflammatory Drugs

A recent case-control study found a protective effect of self-reported use of nonsteroidal anti-inflammatory drugs (NSAIDs) against glioblastoma 45 . A previous cohort study of low-dose aspirin users had found a significantly increased risk of brain cancer 46 . This does not contradict the hypothesis that NSAIDs could protect against glioma, however, as the excess was entirely in the 1st year of follow-up and could well have been an artifact resulting from use of aspirin to relieve symptoms of an as yet undiagnosed tumor, and for follow-up in excess of 5 years there was in fact a nonsig-nificantly reduced risk similar to that observed in the case-control study.

Antiinflammatory compounds

Brain inflammation and activation of microglia are early pathological events in AD, and epidemiological studies have suggested that nonsteroidal anti-inflammatory drugs (NSAIDs cyclooxygenase (COX)-1 and -2 inhibitors) may slow disease onset. Initial retrospective studies of patients with AD using indomethacin 42 showed a positive effect in reducing AD progress.54 However, prospective trials with NSAIDs, e.g., rofecoxib 43, celecoxib 44, and naproxen, failed to demonstrate efficacy in AD. Nonetheless, the COX-1 inhibitor, (R)-flurbiprofen 45, is in Phase III AD trials, despite limited benefit in a Phase II study. Nitroflurbiprofen (NCX-2216 46), an NO-donating flurbiprofen derivative, with reduced gastrointestinal side effects, is also in Phase II trials in AD. In preclinical studies, nitroflurbiprofen reduced lipopolysaccharide-induced microglial activation and decreased both the microglial activation and the amount of Ab deposits in the brains of transgenic mice with familial AD...

Antiinflammatory agents

Minocycline 87, a tetracycline antibiotic with anti-inflammatory activity, appears to have multiple effects on cell function, including inhibition of the mitochondrial permeability transition-mediated release of cytochrome c, an event key to the initiation of the apoptotic cascade. Additional activities of minocycline include inhibition of reactive microgliosis, caspase-1, caspase-3, and nitric oxide synthase transcriptional upregulation, and of p38 MAPK activation. It protects against motor neuron loss in a mouse ALS model (SOD-1 G93A) alone or in combination with creatine.87 The COX-2 inhibitor, celecoxib 44, preclinically slowed motor neuron deterioration in an organotypic model of motor neuron disease and improved survival up to 30 following oral administration in an ALS transgenic model.87 COX-2 is upregulated in both the transgenic SOD-1 G93A mouse model and in the CNS of ALS patients.86 COX-2 catalyzes the conversion of arachidonic acid to prostaglandin E2, a proinflammatory...

Anti Inflammatory Cytokines

Multiple mechanisms have been postulated to underly the therapeutic efficacy of IFN-b modulation of cytokine production toward anti-inflammatory cytokines inhibitory effects on proliferation of leukocytes and antigen presentation and inhibition of T cell migration across the blood-brain barrier by downregulating the expression of adhesion molecules, and inhibiting the activity of T cell matrix metalloproteinases.

Brain Functional Proinflammatory Stimulatory and Antiinflammatory Inhibitory Cytokine Balance

Data continue to accumulate that cytokine positive and negative feedback systems and a balance between stimulatory and inhibitory cytokines may be pivotal for an appropriate modulation of cellular responses in the brain. An unopposed proinflammatory cytokine response cascade could aggravate the magnitude of neurological and neu-ropsychiatric manifestations and may influence wasting and cachexia 36 . This relevant concept that focuses on the temporal profile of proinflam-matory and anti-inflammatory cytokines and their relationship balance during a pathophysio-logical process or disease condition is applicable to all systems. The notion of proinflammatory anti-inflammatory cytokine balance (e.g. IL-1p IL-1 receptor antagonist) could be extended to a model of pro-catabolic pro-anabolic cytokine balance based on new accumulating evidence. For instance, IL-1 p and TNF-a act as pro-catabolic and IL-15 as pro-anabolic cytokines. IL-15 in fact inhibits skeletal muscle wasting in...

Anti Inflammatory Strategies

Some of this cellular inflammatory response appears to continue for weeks and perhaps months, and may play a role in both secondary damage and repair processes.74 Considerable evidence exists to support the idea that much of this cellular inflammation can amplify the secondary injury process, and therefore should be inhibited via anti-inflammatory, immunosuppressive, or antiproliferative agents. With regard to the latter mechanistic possibility, a recent study in a rodent TBI model has shown that there is a considerable posttraumatic increase in cell cycle proteins, many of which have kinase activities.75 In the same study, the administration of the cell cycle inhibitor flavoperidol decreased posttraumatic elevations in neuronal and astrocyte cyclin D1 expression, reduced neuronal damage and astrocyte proliferation, and improved neurological recovery.

New oral antiinflammatory antioxidants

AGI-1067 (succinobucol 44, Figure 15), a metabolically stable derivative of probucol, where the introduction of a monosuccinate ester group alters its overall in vitro and in vivo pharmacology, is a new oral antioxidant being tested in atherosclerosis. AGI-1067, like probucol, is a potent extracellular antioxidant but has an enhanced intracellular uptake capability compared to probucol. AGI-1067 inhibited intracellular ROS production whereas probucol had no effect and also inhibited proinflammatory gene expression in stimulated endothelial cells, including the expression of several proteins associated with atherosclerosis VCAM-1 and MCP-1.93 In LPS-challenged mice, oral dosing with AGI-1067 reduced VCAM-1 and MCP-1 mRNA levels. In LDLr 7 mice, AGI-1067 reduced aortic atherosclerosis by 49 in the absence of a lipid-lowering effect.94 Like probucol, oral dosing with AGI-1067 inhibited restenosis in phase II trials, but an important antiatherosclerotic effect was observed in the...

New antiinflammatory treatments

COPD is characterized by inflammation of the airways, with increased numbers of activated macrophages, neutrophils and CD8+ T lymphocytes. Corti-costeroids are largely ineffective at suppressing this inflammatory process, prompting the search for new anti-inflammatory drugs. There are several approaches to inhibiting neutrophilic inflammation (Table 11.1).

Antiinflammatory Drugs

Anti-inflammatory agents, specifically corticosteroids, are frequently used to reduce the inflammatory reaction to organ allografts. The proposed mechanism of action of these natural hormones and their synthetic analogues is to block the synthesis and secretion of cytokines, including tumor necrosis factor (TNF) and IL-1, and other inflammatory mediators, such as prostaglandins, reactive oxygen species, and nitric oxide, produced by macrophages and other inflammatory cells. The net result of this therapy is reduced leukocyte recruitment, inflammation, and graft damage. Very high doses of corticosteroids may inhibit T cell secretion of cytokines or even kill some T cells, but it is unlikely that the levels of corticosteroids achieved in vivo act in this way. Newer anti-inflammatory agents are in clinical trials, including soluble cytokine receptors and anticytokine antibodies.

Nonsteroidal Antiinflammatory Drugs

These drugs are so called because, like adrenocortical steroids (see below), they reduce inflammation, especially in joints, but also in other tissues. NSAIDs include aspirin (also present in many over-the-counter drugs), acetaminophen (also sold as Tylenol and present in many other combination drugs), celecoxib (sold as Celebrex), ibuprofen (sold under many names, including Advil, Nuprin, and Motrin), and rofecoxib (sold as Vioxx). These are probably the most widely used drugs on the market. NSAIDs are taken for arthritic pain and for headache, among many other indications. Avoiding these pain relievers is out of the question for most people. If you do find yourself in need of a pain reliever, do not take any of these drugs for more than a few days at a time.

Anticytokine and Antiinflammatory Agents

Both progestagens and the polyunsaturated fatty acid EPA 139 have anti-cytokine properties and have been discussed above. EPA is also an anti-inflammatory agent. Non-steroidal antiinflammatory drugs (NSAIDs) have been studied alone and in combination with other drugs and there are data to support a role for them in the management of cachexia 140-143 . An NSAID and progestagen combination has activity in patients with advanced gastrointestinal cancer with effects on weight and quality of life and the combination deserves further study 144 . Selective cyclo-oxygenase-2 (COX-2) inhibitors may also modulate cachexia with an improved side-effect profile over traditional NSAIDs but they require further investigation 145-147 . While there is experimental evidence in tumour-bearing animals that NSAIDs may beneficially affect skeletal muscle mass 148 , it is also important to note that the interaction between inflammation and muscle repair is incompletely understood 149 and there are...

Anti Inflammatory Approaches

Cellular levels of cyclic AMP (cAMP) regulate T cell activation and endothelial adhesion, the synthesis and release of pro-inflammatory cytokines (IFN-g, TNF-a, IL8, etc.) from macrophages and monocytes, and the generation of nitrous oxide and superoxide from neutrophils. PDE4A, PDE4B, and PDE4D are the predominant cAMP-hydrolyzing PDEs in most inflammatory cells, and their inhibition is associated with broad anti-inflammatory effects. The contribution of PDE7 activity to this process is now no longer considered significant.56 In the rat DSS model of colitis, the PDE4 inhibitors rolipram (9) (10mgkg_ four times per day, intraperitoneally) and OPC-6535 Tetomilast (10) (1 mgkg _ 1, four times per day, orally) significantly reduce the extent of mucosal erosion, bleeding, and inflammation.57'58 There is tremendous structural diversity reported for PDE4 inhibitors,59 but, as a class, their therapeutic utility and clinical development had been historically dogged by dose-limiting nausea and...

Other Antiinflammatory Agents

One of the most promising studies to look at anti-inflammatory agents was a landmark trial from Lundholm et al. 27 . In a placebo-controlled trial, these investigators found that indomethacin resulted in an improvement in survival in advanced cancer patients with the anorexia weight loss syndrome. Since then, other studies have suggested that non-steroidal anti-inflammatory agents may play a role in treating this syndrome 28 . Although direct antineoplastic effects may be at work in achieving these benefits, the implication that the cancer anorexia weight loss syndrome is mediated by inflammation suggests that these agents might also be directly treating this syndrome. Further confirmatory clinical studies and further mechanistic studies with these agents in this setting are indicated.

Neurodegenerative Diseases

Based on the newer hypotheses of AD causality there are four active approaches to identifying new drugs to treat AD (1) preventing or reducing A 42 formation (2) reducing tau hyperphosphorylation (3) inhibiting neuronal apoptosis and (4) reducing brain inflammation. Progress in these initiatives has been slow. Inhibitors of the enzymes responsible for the formation of A 42 have been difficult to develop in the absence of true animal models of AD while a novel vaccine approach to aid in the clearance of A 42 encountered toxicity problems in clinical trials. Enzyme inhibitors to prevent tau hyperphosphorylation have also been difficult to identify given the multiple sites on tau amenable to phosphorylation and the diverse group of kinases that can act on these sites. Based on a positive retrospective analysis of the efficacy of the nonsteroidal anti-inflammatory drug (NSAID) indomethacin, reducing brain inflammation appeared to hold promise for AD treatment. However, prospective trials...

With Antithrombotic And Antiplatelet Drugs

Aspirin irreversibly inhibits cyclooxygenase I, preventing platelet synthesis of thromboxane A2, a potent vasoconstrictor and stimulator of platelet aggregation. It is indicated for all patients with ST elevation and non-ST elevation ACSs and it reduces the rate of death or MI by about 50 (26). Despite clear evidence of benefit in all patient subgroups with acute coronary syndromes, aspirin is frequently underutilized. In the Global Unstable Angina Registry and Treatment Evaluation Study (GUARANTEE) Registry (27) of unstable angina patients, only 82 of patients received aspirin. In subjects without known cardiac disease enrolled in the Physicians' Health Study (28), the benefits of aspirin were shown, particularly in those with higher serum concentrations of CRP. In this setting, CRP may be serving predominantly as a marker of those at the highest risk for adverse events. However, part of the benefit of aspirin could relate to its antiinflammatory properties, which could reduce plaque...

Physicochemical Basis of Pain Intervention

Pain management can be approached by intervening at various points of the nociceptive pathway. Transduction is the conversion of the peripheral stimulus at the nociceptor into an electrical signal (35). Agents that have been shown to work at the periphery include nonsteroidal anti-inflammatory agents and capsaicin. Transmission is the afferent ascendance of the electrical signal from the periphery to the neuraxis. Local anesthetics temporarily block transmission. Modulation (i.e., inhibition or facilitation) occurs at the level of the interneurons and supraspinal pathways (36). Opioids, tricyclic antidepressants (TCAs), and GABA agonists are some of the agents effective in manipulating suppression of perceived pain (37).

Paradoxical Control of Inflammation Influences Clinical Outcome in Head and Neck Cancer

Such a paradoxical beneficial effect of Treg (or at least Foxp3 positive T cells) has also been reported in colorectal cancer in man (Salama et al. 2009) and on the induction of colon cancer (Erdman et al. 2003, 2006) or spontaneous intestinal adenoma (Erdman et al. 2005) in mice. It is striking that the tumors in which Foxp3 positive T cells have been reported to be of favorable prognosis are highly inflammatory. We think that the overall interpretation of these data is that in inflammatory tumors, high numbers of infiltrating Treg are beneficial in terms of local control by their anti-inflammatory activities whereas activation of a tumor specific memory CD8 T cell response is necessary to control metastatic spread and OS (Badoual et al. 2009) (Fig. 4). Other inflammatory cytokines (TNFa, IL-1 ) will induce cyclooxygenase 2 (COX-2) that converts arachidonic acids to PGE2, a prostaglandin responsible for various immunosuppressive activities. Indeed, PGE2 has been reported to enhance...

Principles of Pediatric Pain Management

Third, give analgesics by pain intensity. Mild-to-moderate pain should be managed with nonsteroidal anti-inflammatory drugs (NSAIDs) and oral weak opioids. Severe pain is managed by oral strong opioids or intravenous opioids and regional blockade techniques. Transdermal systems of opioids have little application in acute pain but are continued if the patient with chronic pain receiving this technique is admitted for acute exacerbation of pain.

Alkene oxide substrates

Some drugs contain an unconjugated alkene group undergoing CYP-catalyzed epoxidation followed by EH-catalyzed hydration. Thus, the anti-inflammatory agent alclophenac contains an O-allyl group. Its epoxide (16, Figure 9) was found as a stable metabolite in the urine of mice and humans, and so was the diol, proving the involvement of the epoxide-diol pathway in the metabolism of this drug. The epoxide proved mutagenic, but only in the absence of a rat liver S-9 suspension (which contains EH).30 A few old barbiturates also contain an allylic group in the 5-position, e.g., allobarbital (17, Figure 9 R allyl), and secobarbital (17, Figure 9 R 1-methylbutyl). These compounds were substrates of the epoxide-diol pathway in rats and guinea pigs. The relative importance of this metabolic route was species dependent, but was also markedly influenced by the nature of the other C5-substituent.31

Substrates of methyltransferases

Figure 10 also shows the main methylation reactions seen in drug metabolism. O-Methylations (Figure 10a) are common reactions of compounds containing a catechol moiety, with a usual regioselectivity for the meta position. The substrates can be xenobiotics and particularly drugs, l-DOPA being a classic example. More frequently, however, O-methylation occurs as a late event in the metabolism of aryl groups, after they have been oxidized to catechols (see Figure 8). This sequence was seen, for example, in the metabolism of the anti-inflammatory drug diclofenac, which in humans yielded 3'-hydroxy-4'-methoxy-diclofenac (23, Figure 11) as a major metabolite with a very long plasma half-life.44 The rates of O-methylation of about 50 substrates in recombinant human soluble COMT has been published and analyzed by partial least squares (PLS) QSAR and 3D-QSAR.45'46 The compounds examined were natural products. The results showed that increased acidity of the catechol group and a larger size of...

Fields Of Expertise Within Toxicology

Among the drugs that can decrease immunological competence are anti-inflammatory steroids, cyclosporine, and tacrolimus. Certain of these compounds are used to prevent transplant rejection, but they simultaneously carry the risk of allowing infection to occur. The aplastic anemia caused by the bone marrow toxicity of benzene was described above. Lead and chlorinated aryl hydrocarbons such as hexachlorobenzene also can cause bone marrow suppression.

Figure 15 Structure of the cofactor uridine5diphosphoaDglucuronic acid 39 UDPGA generic reactions of O and

An important pathway of O-glucuronidation is the formation of acyl-glucuronides (Figure 15a). Substrates are numerous nonsteroidal anti-inflammatory arylacetic and 2-arylpropionic acids (e.g., ketoprofen, 43 in Figure 16) and aliphatic acids (e.g., valproic acid, 44 in Figure 16). More recent drug classes such as statins and endothelin receptor antagonists may also yield acyl-glucuronides. Aromatic acids do not appear to be good substrates, but there are exceptions. The significance of acyl-glucuronides has long been underestimated. Indeed, these metabolites are quite reactive, rearranging to positional isomers and binding covalently to plasma and seemingly also tissue proteins.84,85 Thus, acyl-glucuronide formation cannot be viewed solely as a reaction of inactivation and detoxification.

Pain Associated With Common Infections

There have been very few studies looking specifically at analgesic use in otitis media. Bertin et al. (72), in the only randomized, double-blind, placebo-controlled trial of analgesic usage in otitis media, reported that for dosing at three times daily, pain persisted in 7 of the children with ibuprofen, 10 with acetaminophen, and 25 with placebo. Although not statistically significant, their data implies that nonsteroidal anti-inflammatory agents are probably more effective than acetaminophen for this common pain problem. Fixed preparations of acetaminophen and opioids, such as codeine, are often recommended for more pronounced pain in otitis media, although their use has never been formally studied. Hauswald and Anison (73), however, in an interesting study of emergency room physicians, reported that they were more likely to prescribe narcotic analgesics for adults with severe pain associated with otitis media that prevented them from sleeping than they were for children with the...

Prevention of Elevated Troponin Levels After PCI

The use of other classes of drugs has also been examined in relation to the incidence of post-PCI troponin elevation. Intravenous nitroglycerine started immediately after PCI and continued for 12 h was shown to be superior to placebo in reducing the frequency of troponin I elevation > 0.1 pg L at 12 h post-PCI (5 vs 19 p 0.036) (42). This finding may be related to the improved coronary blood flow and myocardial perfusion that occur with iv nitroglycerine. Interventions that induce ischemic preconditioning, such as nico-randil, may also reduce the frequency of minor myocardial damage during PCI (43). A randomized, placebo-controlled trial of atorvastatin (40 mg d) started 7 d prior to PCI demonstrated a marked reduction in troponin I elevation (20 vs 48 p 0.0004) in the first 24 h after PCI (27). Given the effect of atorvastatin on reducing CRP levels and the association of CRP with elevated troponin post-PCI (26), it has been postulated that atorvastatin prevents periprocedural...

Multiplicity and ligand selectivity

CYP2C9 with the flurbiprofen bound shows an important salt bridge interaction between an active site Arg108 residue and the charged carboxylate of this nonsteroidal anti-inflammatory drug, which helps explain this isoform's relative selectivity for acidic substrates.16 A comparison of the active site of CYP3A4 and CYP2C9 is depicted in Figure 1. In some cases, ligands have been crystallized within the P450 active site in multiple conformations, highlighting the plasticity of mammalian P450 active sites. This is in accord with the long-held observations of the broad substrate specificity of these enzymes.11

Selected Methods for Experimental Design

In the case of the aromatic substitution, one first compares the unsubstituted compound with the 4-chloro derivative. If the latter is more active, one continues by preparing the 3,4-dichloro derivative. Should this lead to a further increase in activity then the 3-CF3, 4-C1 and the 3-CF3, 4-N02 derivatives can be considered as candidates for maximal activity. The other branches of the tree are followed analogously. As an example, with phenyl tetrazoles of type (1), the unsubstituted compound showed a higher anti-inflammatory activity than the 4-chloro derivative. Consequently, the chlorine was replaced by 4-methoxy, which reduced activity even further. Under these circumstances the scheme suggests the 3-chloro derivative, which in the present example, was indeed the most active compound (along with the 5-bromo derivative).

Cancer Immunoediting

The recognition of tumor cells and how the unmanipulated immune system can be activated in a developing tumor, even though tumor-specific antigens may be expressed as distinct recognition molecules on the surface of tumor cells, have been controversial topics in the oncology field. As a hypothesis of the so-called danger theory, discussed in detail in Chapter 3, it was considered that cellular transformation did not provide sufficient proinflammatory signals to activate the immune system in response to a developing tumor. In the absence of such signals, there is often no immune response, and tolerance may develop. However, studies have indicated that danger signals, such as buildup of uric acid, presence of potential toll-like receptor ligands (e.g., heat shock proteins), the occurrence of a ligand transfer molecule in the signaling cascade induced by CpG DNA, and the presence of extracellular matrix (ECM) derivatives, may induce proinflam-matory responses that activate innate immune...

Studies in MS and Other Conditions

Experimental studies indicate that the components of bee venom have biologic effects that could affect an inflammatory disease such as MS. Various mixtures of multiple venom proteins produced anti-inflammatory effects in one study. Other studies have shown that two specific components of venom, melittin and adolapin, also have anti-inflammatory properties. In contrast, other studies have shown that bee venom components actually cause an inflammatory response. Also, apamin, a chemical constituent of the venom, has some effects that could be beneficial for MS. Apamin inhibits the action of a component of the nerve cell known as the potassium channel. This is the same part of the nerve cell affected by the experimental drug 4AP (4-aminopyridine), which may be beneficial for MS-associated fatigue. However, it is not clear that bee venom therapy produces high enough levels of apamin in the central nervous system to significantly inhibit potassium channels. Further studies are needed in...

Ontogenic development

By UGT2B7.107 Morphine was found to undergo significant glucuronidation by the fetus liver. In vitro studies in hepatic microsomes obtained from fetuses (15-27 weeks) indicated that the glucuronidation rates were 10-20 of that observed in adult microsomes.108 In addition, the mean rate of morphine glucuronidation in fetal livers obtained after hysterectomy was twofold higher than that obtained from induced abortion livers, suggesting a possible regulatory mechanism for UGTactivity related to the birth process (Table 4).25 The glucuronidation of morphine in vivo has also been demonstrated in premature neonates as young as 24 weeks of gestation. Studies with other substrates which are mainly or partially glucuronidated by UGT2B7, such as naloxone, an opiate agonist, benzodiazepines, and nonsteroidal antiinflammatory drugs are all suggestive of a reduced glucuronidation ability in neonates compared to adults.109

Annexin 1 And Inflammation

Annexin 1 is predominantly an intracellular protein initially identified as a major target for phosphorylation by the epidermal growth factor receptor (EGFR). It is expressed at high levels in many cell types and has a crucial role in EGF-mediated inward vesiculation of the EGFR (White et al., 2006). Signalling through the EGFR leads to stimulation of the MAP kinase pathway via an intermediate complex involving p21 ras and Grb2. Annexin 1 appears to competitively inhibit recruitment of this intermediate when cells are exposed to glucocorticoids, becoming phosphorylated and associating with EGFR-containing vesicles (Croxtall et al., 2000). Normal signalling through the MAP kinase pathway leads to relocalisation of the cytoplasmic phospholipase A2 (cPLA2) to membranes where it is involved in the production of the inflammatory second messenger arachidonic acid (AA). By inhibiting this pathway through increased annexin 1 recruitment, dexamethasone can moderate the pro-inflammatory...

B p38 Mitogen Activated Protein map Kinase

Induction of HO-1 in mammalian cells is an indicator of oxidative stress.68 Since HO-1 has antiinflammatory properties,69'70 it is thought that these properties may be the reason for cytoprotection. Support for this idea was obtained by demonstrating diminished tumor necrosis factor-a (TNF-a) production in RAW264.7 macrophages overexpressing HO-1 after exposure to lipopolysaccharide (LPS). Otterbein et al.70 showed in vivo in mice and in vitro in RAW264.7 cells that CO inhibited the expression of LPS-induced proinflammatory cytokines, tumor necrosis factor-a, interleukin 1-0, and macrophage inflammatory protein-10. Moreover, CO enhanced the LPS-induced expression of the antiinflammatory cytokine interleukin-10. Of considerable interest is the fact that the concentrations of CO used in these studies were 10 to 500 ppm (0.001 to 0.05 ). As pointed out by Otterbein et al.,6970 these concentrations of CO are comparable to concentrations used in humans (0.03 ) in the measurement of CO lung...

UDPglucuronosyltransferases EC 24117

In a few cases, however, UGTs enhance the toxicity of their substrates. This is the case with some nonsteroidal anti-inflammatory drugs (NSAIDs). The resulting ester glucuronides can undergo acyl migration, i.e., the intramolecular transesterification from the C1 hydroxy group of the glucuronic acid to the C2 hydroxy group and further to the C3 and C4 hydroxy groups. This can lead to the formation of a free aldehyde group at C1, which can react with primary amino groups in proteins generating Schiff's bases. Amadori rearrangement can then lead to a stable protein adduct, which may give rise to allergic reactions, a well-known drug toxicity of some NSAIDs. Glucuronic acid conjugation can also result in enhanced genotoxicity. Aromatic amines, including important human carcinogens, are metabolized by CYPs (preferentially CYP1A2) to aromatic hydroxylamines. Glucuronidation of these leads to the formation of a (moderately good) leaving group, which after being cleaved off leaves behind a...

CD137 Ligand Activities on Monocytes and Macrophages

The signal through CD137 ligand activates monocytes and the CD137 lig-and signal alone is sufficient for activation. When CD137 ligand is crosslinked by recombinant CD137 protein or an anti-CD137 ligand antibody, it induces adherence of monocytes within a few hours. The adherent monocytes change their shape over the course of a week and adopt the three basic macrophage morphologies, which are round, elongated, and branched cells (Langstein and Schwarz, 1999). Concomitantly with adherence the CD137 ligand signaling induces the expression of proinflammatory cytokines (TNF, IL-6, IL-8, IL-12) and activation markers (ICAM-1), and it inhibits expression of anti-inflammatory cytokines (IL-10) and differentiation markers (FcyRIII), (Laderach et al., 2003 Langstein et al., 1998).

Clinical Role for Troponin Testing in Sepsis

At present, data supporting any clinical application of troponin for prognostic assessment in SIRSs are limited, and, more important, no specific therapeutic strategies that might modify the risk of patients with SIRS have been identified. Application of aggressive antithrombotic, antiplatelet, and invasive therapies effective for patients presenting with ACS and elevated troponin are not supported by clinical data in this setting and may expose patients with sepsis to additional, unacceptable risks. Specific anti-inflammatory therapies such as antibodies to TNF-a have shown promising preliminary results. Research providing additional insight into the pathogenesis of troponin elevation in sepsis may also further clarify the mechanisms underlying myocardial dysfunction and guide the development of new approaches to the treatment of this highly morbid syndrome (33).

Regulation Of Proinflammatory Signaling Pathways By Parp

In addition to its effect on transcription factor activation, PARP inhibition attenuates IL-1P-mediated iNOS expression in rodent pancreatic beta islet cells and in activated macrophases.62-65 Similar anti-inflammatory effects have been noted in vitro in murine macrophages and in vivo in rats. PARP inhibition has been shown, for example, to suppress endotoxin-induced expression of TNF-a, IL-6, iNOS, and cyclooxygenase-252 and to elevate the expression of the anti-inflammatory cytokine IL-10.52 These effects are associated with the near total blockade of endotoxin-medi-ated induction of MAP kinase activity.52 Since MAP kinase plays a major role in the pleiotropic transduction of intracellular inflammatory cascades, the anti-inflammatory effects of PARP inhibition may be accounted for at this level of gene regulation. One may also expect that PARP-dependent regulation of NF-kB activation66,67 has a pleio-tropic effect on the expression of proinflammatory genes, given the broad role that...

A paradigm for evaluating neuronal assemblies as indices of depth of consciousness pain

One of the most empirically tractable paradigms for exploring neuronal correlates of consciousness is pain. Acute pain is an unpleasant sensation that serves as an alerting mechanism to warn the organism of the potential for injury. There are many good animal models of acute pain and these have led to the development of many effective analgesics, ranging from non-steroidal anti-inflammatory drugs (NSAIDs), to opioids and local anesthetics. Moreover, painful stimulation and its alleviation can be readily standardized within an experimental protocol on the other hand, the subjective sensation of pain is highly variable and dependent on a host of other factors within the brain body. Indeed, a distinction is traditionally made between no-ciception,'' i.e., the physiological process of pain signals, as opposed to the subjective experience of pain the former does not require an ongoing conscious state, while the latter does. It has previously been suggested that these diverse factors, both...

Toll Like Receptor

The TLR-4 intracellular and transmembrane domains interact with a number of adaptor proteins extensive mutagenesis experiments have been performed on the cytoplasmic region of TLR-4 to identify specific regions of the protein required for these interactions (168). The Toll-like receptors contain three conserved sequences in their cytoplasmic regions, termed 'boxes' (173). In macrophages, two structural surfaces of the TLR-4 cytoplasmic domain were required for downstream activation of the pro-inflammatory IL-12 p40 and antiinflammatory IL-10 promoters, as well as for downstream activation of minimal promoters dependent on individual transcription factors (168). The same regions were required for activation of all promoters tested, suggesting that the signaling pathways diverge downstream of the adaptors (168). One of the major cellular adaptor protein identified for TLR-4 signaling is myeloid differentiation factor

Preemptive Preventive Analgesia

Recent studies have demonstrated that preventive analgesia is associated with clinically important reductions in CPSP incidence and intensity. For example, the use of bone graft from the hip is a necessary expedient in certain types of reconstructive surgery, but CPSP at the graft removal site is reported in up to 37 of patients at one year and 19 at two years 66-68 . Reuben et al. 69 showed that infiltration of morphine into the bone graft harvest site reduced acute and chronic donor site pain sixfold. Another study 70 demonstrated that chronic donor site pain was reduced from 30 to 10 simply by giving a non- steroidal antiinflammatory drug one hour prior to surgery and for five days afterwards. Pre-treatment of a similar nature in patients having outpatient anterior cruciate ligament repair -71 was associated with fewer complications and higher activity levels when measured six months postoperatively, an example of how a simple preventative measure taken at the time of surgery can...

Inflammatory pathway in atherosclerosis biological basis of biomarkers in prediction and prognostication in

Recognition of the role of inflammation as a master regulator of atherogenesis has provided a fresh intellectual construct for understanding this disease. This new scientific foundation for understanding atherogenis also furnishes insights into novel therapeutic targets that may assist its mitigation. While inflammation biology currently furnishes new insights into the mechanism of benefit of existing therapeutics, the promise of targeted anti-inflammatory interventions to prevent or treat atherosclerosis will require much greater time and effort. Yet, one type of practical application of inflammation biology promises favorable outcome in terms of more prompt clinical applicability. Biomarkers of inflammation may soon merit inclusion in clinical application, the topic of many contributions to this volume.

Inflammatory Biomarkers and Clinical Utility

A more optimistic position would argue that residual risk indicated by inflammatory biomarkers in an optimally managed patient could provide impetus for intensification of lifestyle measures to ameliorate the individual's inflammatory profile. Weight loss, dietary interventions, smoking cessation, and regular physical activity may all mitigate inflammation beyond pharmacotherapy. Statins have received the greatest attention as pharmacological modifiers of inflammatory biomarkers. However, increasing evidence supports the possibility that other classes of medications may likewise modulate inflammation. Although aspirin has not consistently reduced levels of CRP, emerging evidence suggests that fibric acid derivatives, thiazolidinediones, and metformin can reduce such levels. The fibric acid derivatives can limit inflammation by activating peroxisome proliferator activated receptor-a (PPAR-a). The thiazolidinediones (e.g., the glitazone class of insulin...

Treatment of Graves Disease

When managing the problems of active Graves' disease, the following measures are known to be of benefit maintenance of a euthyroid state, avoidance of cigarette smoking (very important), use of topical hydrating agents (with or without preservatives, as needed), and nonsteroidal anti-inflammatory drugs. These are largely supportive therapy, allowing time to pass and inflammatory activity to subside, while protecting vision in the meantime. This is adequate for a majority of cases. Infrequently, one encounters cases of fulminant inflammatory disease that threaten destruction of the eye through extreme exposure of the ocular surface and formation of corneal ulcers, or by compression of the optic nerve, which can destroy vision to the point of no light perception. The use of orbital irradiation and or surgical decompression should be saved for these very dangerous, high-risk cases. High doses of oral corticosteroids, such as 1 mg kg of body weight of prednisone, can be used

New Research Areas

Antiapoptotic agents (e.g., caspase inhibitors), anti-inflammatory agents (e.g., minocycline 87), bioenergetic enhancers antioxidants (e.g., creatine, coenzyme Q, lipoic acid, dicholoroacetate, cystamine), excitotoxic anatgonists (e.g., riluzole 88, remacemide 89), histone deacetylase inhibitors (sodium butyrate and suberoylanilide hydroxamic acid), and transcriptional inhibitors (e.g., mithramycin 90) have all been examined in the R6 2 mouse model of HD and have shown some benefit.84 Some of these agents have been advanced to clinical trials (Table 2). Aggregation inhibitors are also a target.85

Attenuating Treg Function

Nonsteroidal anti-inflammatory drugs including aspirin have the ability to block the production of tumor-derived prostaglandin E2 (PGE2). This prostaglandin can induce Foxp3 expression and promote Treg inhibitory activity in vitro. The inhibition of PGE2 production therefore can be potentially used to limit Treg function in vivo. The specific use of COX-2 inhibitors, which reduce production of PGE2, significantly reduces Treg infiltration in mouse tumors. Furthermore, when PGE2 production was inhibited by Indomethacin in patients with colorectal cancer, Treg-mediated anti-tumor suppression was reversed (Yaqub et al. 2008). In addition, in patients with colon cancer randomized to treatment with either indomethacin celebrex or a control drug prior to tumor resection, CD8+ tumor-infiltrating T-cells were increased while decreased expression of Foxp3 and IL-10 was found in the COX2 inhibitor cohort (Lonnroth et al. 2008).

Classification Of Aa Based On Etiology And Pathophysiologic Mechanisms

Medical drugs have been frequently implicated as causes of AA.6 Cytotoxic agents may serve as a prototype, and a patient's medical history should make a diagnosis obvious. Of importance are drugs used for treatment of unrelated disorders. Chloramphenicol and AA as well as aminopyridine and agranulocytosis are the best examples of agents recognized to be associated with an increased risk of disease.44-46 In general, drug reactions can be classified into dose-related effects and idiosyncratic reactions, in which occurrence is rare and not dose dependent. The list of drugs that have been implicated in causing AA is long, but all of them can account only for a fraction of cases (around 15 ). The most comprehensive epidemiologic study performed in Europe identified agents that were associated with the occurrence of AA, but for most of the cases the stratified risk estimate was relatively low. The highest risk was found for some nonsteroidal anti-inflammatory drugs (NSAIDs) (piroxicam),...

Inflammation In Alzheimer Dementia

There is now substantial epidemiological evidence of the involvement of inflammation in Alzheimer's dementia. There are now about 20 reports on the incidence of Alzheimer's dementia in populations with a long antiinflammatory drug consumption history. Nearly all of these studies showed a lower AD incidence with a decrease of 50 or a delay in onset of 5-7 yr, and, in one prospective study, the relative risk fell with increasing duration of drug use (16). Clinical trials with indomethacin or propentofylline, another agent with antiinflammatory properties, showed both a significant cognitive improvement (17,18), whereas one study on diclofenac and one recent study on hydroxychloroquine did not demonstrate a positive effect on the progression of the disorder (19,20). Alzheimer's dementia shows an apolipoprotein E (ApoE) genotype susceptibility with ApoE4 as a risk factor. Interestingly, ApoE4 seems essential

Neuroinflammatory Imaging

Visualizing neuro-inflammation in Alzheimer's dementia is of interest, first for clarifying the pathophysiology, second for selecting patient subgroups that are more eligible for antiin-flammatory treatment, and finally for monitoring patients during trials with these antiinflammatory agents. Here we review and discuss current neuro-inflammatory imaging modalities, both structural and functional. Structural imaging aims to describe in detail the spatial relationship of neurodegenerative and inflammatory consequences like mass effects, edema, vascular congestion, thrombosis, petechial hemorrhages, secondary demyelinization, gliosis, and finally neuronal destruction, necrosis, or atrophy, as well as visualizing other (nonspecific) structural changes.

Aspirin and Other Antiplatelet Agents

The ability of antiplatelet therapy to prevent future cardiovascular events appears to vary by hsCRP level. In the Physicians' Health Study, a large primary prevention trial, the reduction in risk of future MI associated with assignment to aspirin (325 mg on alternate days) was 56 (p 0.02) among participants with baseline hsCRP levels in the highest quartile and declined with hsCRP levels such that a reduction of only 14 (p 0.80) was observed among those in the lowest quartile, suggesting that aspirin may prevent ischemic events through anti-inflammatory as well as antiplatelet effects (39). Similarly, observational data indicate that the beneficial effects of clopidogrel and abciximab may be greatest in patients with elevated CRP levels prior to percutaneous coronary interventions (111-113). On the other hand, ticlopidine was associated with a significant risk reduction in subsequent cardiovascular events among ischemic stroke patients with admission hsCRP levels in the bottom two...

Radionuclide Approaches

Patients with symptomatic MACE often have many lesions that meet the histologic criteria for vulnerable plaque. The stimuli leading to rupture of the culprit lesion also act on the remaining lesions, contributing to the high incidence of recurrent events that often occur during recovery. Managing patients with MACE must address both the acute event (usually with a percutaneous intervention) and reduce the likelihood of another event during convalescence. To reduce the possibility of another event, aggressive pharmacologic therapies are advocated to reduce inflammation and stabilize the remaining vulnerable lesions. An alternative approach may be the immediate stabilization of these vulnerable non-culprit lesions using a percutaneous catheter-based intervention applied at the time of the emergency percutaneous intervention therapy for the patient's acute coronary event. A major challenge to this therapeutic approach is identifying and localizing these lesions with certainty. Since many...

Therapeutic Vaccines and Toleragens

Glatiramer acetate is the first vaccine that has been used to treat an autoimmune disease - in this case RRMS32 it was approved by the US FDA in 1996. It is a mixture of many synthetic peptides - random polymers - that mimic the antigenic portion of MBP. It reduces the relapse rate in RRMS, impacts MRI markers of disease activity, is well tolerated, and does not appear to induce the formation of neutralizing antibodies. Several mechanisms of action have been proposed for glatiramer acetate, none of which reflect the theoretical mechanism proposed above for a prophylactic vaccine. Glatiramer acetate is a strong inducer of Th2 cells, and thus anti-inflammatory cytokine production one proposed mechanism is that it acts by inducing a Th1 to Th2 shift. In addition to glatiramer acetate, a vaccine for MG is in preclinical development.31

Prediction ofClinical Recurrence After Percutaneous Coronary Intervention

The concept of clinical recurrence is of particular interest when considering patients undergoing percutaneous coronary intervention (PCI), whether for management of ACS or in patients undergoing elective PCI. In the current era of continued frequent use of bare-metal stents in some regions of the world, clinical restenosis after PCI in patients with ACS is expected in approx 20 of patients. Evidence provided by some studies suggests that the recurrence of clinical events after PCI is confined to patients with high CRP levels (21-24). In these studies, the risk of death or MI following PCI in patients with low CRP levels (< 3-5 mg L) was very low (< 1 ) (21-24). This observation may have important consequences for follow-up and treatment of patients with ACS managed with contemporary early invasive therapy. Versaci et al. (25) have showed that by targeting potent anti-inflammatory therapy (high-dose prednisone) to those patients with effort-induced stable angina pectoris and high...

Ten Aspects To Consider for Future Research into Brain Mechanisms Involved in Wasting and Cachexia

A pivotal area of research will continue to be on the cytokine balance characterisation and on how cytokines interact sequentially and in parallel during wasting and cachexia. The concepts of proinflammatory anti-inflammatory and pro-catabolic pro-anabolic cytokine balance remain a key area to define contributory mechanisms in wasting and cachexia.

MPO as a Marker for Oxidative Stress

(NO), thereby reducing NO bioavailability and impairing its vasodilatory and antiinflammatory functions (53,54). Two recent studies have also revealed that MPO is strongly associated with adverse outcome in patients with ACS (55,56). Particularly in individuals with low troponin levels, MPO identified patients at increased risk for early cardiovascular events that occur within days after the onset of symptoms (Fig. 11) (55). This suggests

Interleukin10 as a Marker ofInflammatory Balance

Inflammatory balance may also play an important role in patients with ACS (57,58). Interleukin (IL)-10 is secreted by activated monocytes macrophages and lymphocytes (59). It has multifaceted anti-inflammatory properties including inhibition of the proto-typic proinflammatory transcription factor nuclear factor-kB leading to suppressed cytokine production (60), inhibition of matrix-degrading metalloproteinases (61), reduction of tissue factor expression (62), inhibition of apoptosis of macrophages and monocytes following infection (63,64), and promotion of the phenotypic switch of lymphocytes into the Th2 phenotype (65). These inflammatory mechanisms have been shown to play a pivotal role for atherosclerotic lesion development and progression, suggesting a potential regulatory role of IL-10. Indeed, numerous recent experimental studies have shown that either systemic or local IL-10 gene transfer not only attenuates atherogenesis (59,66,67) but also affects processes associated with...

Science Medicine and Leadership Win Out The Pendulum Swings in Carvedilols Favor

In addition, the other properties of carvedilol, namely its antioxidant actions, could also provide added benefit inasmuch as oxygen radicals were known to be potent activators of signaling pathways that have a short- and long-term negative impact on cardiac cell growth and survival. In particular, the emergence of apoptosis as a primary mechanism of cardiac cell death43 and remodeling in heart failure mediated in part by intracellular redox imbalance potentially expanded as we had successfully demonstrated in animal studies the potential benefits that this drug might have in heart failure beyond its adrenergic pharmacology. Thus, carvedilol could inhibit apoptotic cell death through modulation of expression of the Fas receptor, which is a cell surface receptor that activates a cell-death-signaling pathway.44-47 Additionally, carvedilol was also shown to possess antiproliferative actions on vascular smooth muscle cells and anti-inflammatory actions through its ability to inhibit...

The Large Intestine Rectum and Anus

Genetic models have been used with some success to examine visceral pain. For example, the Wistar Kyoto rat (a high-anxiety strain) exhibits significantly more colonic hypersensitivity than other strains, including the commonly used Sprague Dawley rat strain (50). Specific transgenic models have been produced with intestinal inflammation, results that have been used to propose the pathophysiology of inflammatory bowel disease (IBD). Such genetic models include the knockout of genes such as that for the anti-inflammatory cytokine interleu-kin-10, which results in increased cytokine production by TH1 lymphocytes and chronic enterocolitis with some IBD-like symptoms (51).

T and B Cell Activation and Costimulation

Antigen-dependent and costimulatory signals, CD4 T and CD8 T cells undergo clonal expansion and differentiate into effector helper and cytolytic T cells, respectively. Activated CD4 T effector cells produce either pro-inflammatory cytokines (Th1), or anti-inflammatory cytokines (Th2).

Atherosclerotic Cardiovascular Disease

Cachexia, by virtue of MICS, may predispose CKD patients to atherosclerotic cardiovascular disease 24, 49, 51 . Dialysis patients with coronary heart disease often have hypoalbuminaemia and elevated levels of acute-phase reactants 24 . Moreover, progression of carotid atherosclerosis during dialysis may be related to IL-6 levels 137 . It should be noted that the cascade of inflammatory factors leading to an acute-phase reaction is counter-regulated by various anti-inflammatory cytokines, such as IL-10. Recently, Girndt et al., in a study of 300 haemodialysis patients 138 , showed that the -1082A allele, which is associated with low production of IL-10, is associated with an increased risk of cardiovascular events. Inflammatory processes may promote proliferation and infiltration of inflammatory cells into the tunica intima of small arteries, including the coronary arteries these processes lead to atherosclerosis and stenosis of blood vessels and consequent coronary and other vascular...

Conclusions and Future Steps

(CHF) and geriatric populations have risk-factor reversal as well 192 . Hence, a better understanding of the role of chronic cachexia in CKD patients may help improve clinical management of not only these patients but also CHF, geriatric, and other vulnerable populations. According to an epidemiological study of over 55 000 haemodialysis patients, if an intervention could increase serum albumin above 3.8 g dl and by doing so improve survival in dialysis patients, almost one-third of all deaths among these patients could be hypo-thetically prevented or delayed. Since approximately 60 000 patients out of over 300 000 haemodialysis patients in the USA die every year, a hypoalbuminaemia-correcting intervention might theoretically prevent 15 000-20 000 deaths every year 25 . If this is correct, there is a great need to develop effective nutritional and or anti-inflammatory interventions and to carry out randomised, prospective, controlled clinical trials to demonstrate the benefits of such...

Other Diseases of the Retina

Diabetic retinopathy (DR) occurs in 27 of diabetics after 5-10 years of contracting diabetes and up to 90 have DR after more than 10 years of diabetes. DR essentially stems from retinal ischemia due to thickening of retinal capillary basement membranes when capillary pericytes start to die off. The ensuing ischemia causes the overexpression of VEGF, which in turn causes capillaries to leak and cause edema. VEGF also stimulates the growth of new blood vessels. This neovascularization could be perceived as a compensatory mechanism, but it is actually detrimental, since the new blood vessels disrupt retinal function. Deterioration of vision in DR is due to macular edema and proliferation of fibrovascular membranes that can lead to retinal detachment. Current treatments for DR are limited to laser photocoagulation of the leaky blood vessels, but this unfortunately destroys the underlying and surrounding retinal tissue. A much more specific approach is the use of photodynamic therapy,...

Ocular Surface Diseases

Allergic conjunctivitis and perennial conjunctivitis are fairly acute ocular surface disorders. However, vernal conjunctivitis, atopic keratonjunctivitis, and giant papillary conjunctivitis are chronic disorders.93 The hallmarks of allergic conjunctivitis are itching, redness, swelling, tearing, and temporary acute photophobia caused by various mast cell mediators released from mast cells when an allergen contacts the conjunctiva. The acute allergic conjunctivitis may develop into a chronic disease if left untreated, and this causes corneal and conjunctival remodeling and ulceration, sometimes accompanied by bacterial infection. Since mast-cell-derived histamine is the major culprit in allergic conjunctivitis, topical ocular antihistamines, such as emedastine, levocabastine, azelastine, and ketotifen, were considered the drugs of choice, often supplemented with vasconstrictors (e.g., oxymetazoline) and edema reducers (nonsteroidal anti-inflammatory agents and corticosteroids)....

The First Step The Discovery of Adrafinil

In the early 1970s, the Research Department of Laboratoire Louis Lafon, a small family-owned pharmaceutical company located in Maisons-Alfort, a suburb of Paris, had focused its research activities in three areas (1) cardiovascular (2) antispasmodics and (3) nonsteroidal anti-inflammatory drugs (NSAIDs) analgesics.

Clinical Trial Issues

Clinical trial designs often employ parallel placebo-controlled and randomized withdrawal types of experimental manipulations.14,35 The majority of these designs have been well validated using opioids however, the relative utility in assessing novel analgesics that target specific aspects of chronic pain (e.g., neuropathic allodynia) await further evaluation (e.g., non-NSAID (nonsteroidal anti-inflammatory drug) mediated analgesia in the third molar extraction model).

For Cellbased Interventive Therapies

Chronic neuropathic pain following damage to the peripheral or CNS has been difficult to treat clinically (14). As an illustration of the severity of pain following spinal cord injury (SCI), patients often report pain, rather than immobility, as the major deterrent to good quality of life (15). Pharmacological pain management is based on nonopioid and opioid analgesics, including nonsteroidal anti-inflammatory drugs (NSAIDs), cyclooxygenase 2 (COX-2) inhibitors (16), calcium channel blockers (17), capsaicin (18), nicotine receptor agonists (19), and opioids (20) (e.g., morphine and its derivatives). Adjunct drugs, such as antidepressants and anticonvulsants, often accompany more antinociceptive agents in certain types of pain, like diabetic neuropathy (21). Gabapentin, an anticonvulsant, has become the most common medication for SCI pain (22), probably owing to its calcium channel-blocking functions (23). Combination of medications, such as NSAIDs with opioids, seems to be more...

DC Function CD137 Expression and Signaling

IL-6 is an anti-inflammatory Th2 cytokine whose expression and function is prominent in myeloid cell development, humoral immune responses, and in certain autoimmune diseases. These include EAE (Ishihara and Hirano, 2002 Samoilova et al., 1998), RA (Hata et al., 2004 Hwang et al., 2004 Nishimoto and Kishimoto, 2004), juvenile diabetes (Scholin et al., 2004 Vozarova et al., 2001), and SLE (Ohteki et al, 1993 Suzuki et al, 1993 Tang etal., 1991). IL-12 is a pro-inflammatory cytokine that promotes the development of Th1 mediated immune responses, it induces T cells to produce IFN-y and drives both innate and adaptive anti-tumor immune responses (Gao etal., 2003 Kodama et al., 1999 Martinet et al., 2002 Parihar et al., 2002 Smyth et al., 2000 Uekusa et al., 2002). How these two opposing cytokines are coordinately regulated following CD137 signaling, and what their physiological roles are in dendritic cell biology and T cell immunity remains to be...

Inflammatory Bowel Diseases

Has been a major focus of research, as IBD is characterized by a hyper-reactive immune system, underlined by a heavy influx of T cells, B cells, monocytes, and neutrophils into the intestinal mucosa. On the simplest level, an imbalance between pro- and anti-inflammatory mediators leads to chronic inflammation in the gastrointestinal tract of patients with IBD. Specific cytokines important for the induction of mucosal immunity and regulation of the mucosal immune responses include the pro-inflammatory mediators IL-1, IL-6, IL-12 and TNF-a, produced by monocytes and macrophages. In addition, the CD4+ T cells infiltrating the lamina propria (LP) of IBD patients display an altered cytokine profile as compared withhealthyindividuals. LP-derived CD4+ Tcellsfrom CD patients produce increased levels of IFN-y and IL-2, whereas LP-derived CD4+ T cells from UC patients produce increased levels of IL-4 and IL-5 (Farrell et al. 2001). These observations suggest that that the immune responses are...

Simultaneous Cross Linking Polymerization

Maitra's group 161,162 reported NIPAM-based copolymer gel ( 50nm) using solution polymerization employing ammonium persulfate ferrous ammonium sulfate (APS FAS) as the initiating system at room temperature for delivery of nonsteroidal anti-inflammatory drugs. We have recently developed poly(N-isopropylacrylamide-covinyl pyrrolidone) poly(NIPAM-co-VP) nanogels with an average size of 40 nm for the delivery of anticancer drugs (Figure 6.13). Other research groups have explored novel methods to form smart core-shell polymeric gels of PNIPAM PEI and PNIPAM PEI chitosan using the same polymerization technique 62,63 . Similarly, well-defined amphiphilic core-shell polymer nanospheres are obtained (60-160 nm) via graft copolymerization of methyl methacrylate (MMA) from water-soluble polymer chains containing amino groups and casein 39,40 . Furthermore, the temperature-sensitive liposomes bearing or modified with poly(N-isopropylacrylamide) are possible to obtain by solution polymerization in...

Bacterial Flora in Inflammatory Bowel Disease

Recent studies have tried to manipulate the intestinal microflora by treating with potentially protective bacteria such as lactobacilli and bifidobacteria species (Campieri et al. 2001), which are harmless components of the normal human and murine gastrointestinal microflora. It has been shown that certain probiotics can induce specific anti-inflammatory effects and they have been proposed as a therapy of colitis (Borruel et al. 2002, 2003). Consistent with this, treatment with Lactobacillus has shown to prevent the development of spontaneous colitis in IL-10-deficient mice (Madsen et al. 1999). The role of lactobacilli and bifidobacteria in human colitis is still not well characterized, although a significant decrease in the number of lactobacilli was found in colonic biopsies from patients with UC (Fabia et al. 1993). Clinical trials with the use of probiotics to treat patients with IBD or pouchitis proved to be quite effective (Gionchetti et al. 2000 Rembacken et al. 1999)....

Nutritional Support

Catecholamines and cytokines, which are elevated in heart failure, are stimuli for free-radical production. Therefore, antioxidants and free radical scavengers, such as vitamins C and E, are therapeutic options in cardiac cachexia. This was proven by a study showing that muscle wasting in mice was prevented by an antioxidant 92 . Additionally, it was shown that antioxidants suppress the production of free radicals in leucocytes 93 . The presence of elevated levels of markers of oxidative stress in heart-failure patients correlates with functional class, reduced exercise tolerance, lower antioxidant levels, and worse prognosis, including cachexia 94, 95 . These patients also tend to have micronutrient deficiency through, e.g. urinary losses or therapy with diuretics. Deficiencies of specific micronutrients, such as selenium, copper, calcium, zinc, or thiamine, can also cause heart failure 96 . Thus, it is important to keep CHF patients on a diet with sufficient calories and with...

Interleukin (IL)-6 was identified as a hepatocyte-stimulating factor more than 10 years ago 1 . Subsequently, the authors have proposed IL-6 to be the major mediator of acute phase protein synthesis in liver cells. IL-6 belongs to the so-called IL-6-type cytokine family comprising, additionally, IL-11, leukaemia inhibitory factor (LIF), oncostatin M (OSM), ciliary neurotrophic factor (CNTF) and car-diotrophin-1 (CT-1). The members of this cytokine family exert pro- as well as anti-inflammatory activities via surface receptors. For IL-6 and IL-11, these surface receptors comprise specific a-receptors and two identical gp130 signal transducer molecules, while, for other IL-6-type cytokines such as CNTF, OSM, LIF and CT-1, one gp130 and one LIF-receptor are involved. Resolution of the three-dimensional structures of IL-6, LIF and CNTF shows that the three cytokines form a bundle of four antiparallel long-chain alpha-helices of an up-up-down-down topology that are connected by loops.

Clinical Role Of Crp Testing

Accumulating evidence suggests that statins may have powerful antiinflammatory effects (39,40). Indeed the risk reduction observed with these agents in large-scale clinical trials have been greater than that explained on the basis of changes in lipid parameters alone. In this regard, several studies have recently demonstrated that statins reduce CRP concentrations, and that this effect is independent of lipid lowering (41-44).

Elements Of Signal Transduction

Most culture cells in the culture medium containing nutrients and vitamins will not proliferate unless key stimulants known as growth factors are supplied. Apart from stimulating (or inhibiting) growth, they may initiate apoptosis, differentiation and gene expression. Their effects are generally long ranges by influencing the growth and function of neighboring cells. Several extracellular signaling proteins interact with cells of the immune or inflammatory systems by activating or modulating the proliferative properties of these cells. Cytokines that induce inflammation are pro-inflammatory mediators, whereas anti-inflammatory mediators reduce it. Chemokines are cytokines that bring about local inflammation by recruiting inflammatory cells by chemotaxis and subsequently activating them.

Mucosal Immunity in the Respiratory System

Alveolar macrophages represent the majority of free cells within the alveolar spaces. These cells are functionally distinct from macrophages in most other tissues in that they maintain an anti-inflammatory phenotype. They express IL-10, nitric oxide, and TGF-P and are poorly phagocytic compared with resident macrophages in other tissues, such as spleen and liver. Alveolar macrophages inhibit T cell responses as well as the antigen presentation function of CD103+ airway DCs.

Immune Privilege in the Eye Brain and Testis The

Vision, which is essential to survival to most mammals, can be easily impaired by inflammation within the eye. Evolved mechanisms that minimize the likelihood of immune responses and inflammation in the eye have been most thoroughly described in the anterior chamber, a fluid-filled space between the transparent cornea in front and the iris and lens behind. Inflammation in this chamber could lead to opacification of the transparent cornea and lens, with loss of sight. At least some of the properties of immune privilege studied in the anterior chamber also apply to other ocular sites, such as the vitreous cavity and the subretinal space. Anatomic features of the anterior chamber that contribute to immune privilege include the tight junctions and resistance to leakiness of blood vessels in the tissues adjacent to the anterior chamber (the so-called blood-eye barrier), the avascular nature of the cornea, and the absence of lymphatics draining the anterior chamber, which limits access of...

Overview of Absorption Distribution Metabolism and Excretion Correlations with Descriptors of Function

Despite the significant role of log P in ADME processes, it is worth noting that predictive equations that successfully correlate lipophilicity with ADME parameters are not as numerous as one would expect.84 This inherent difficulty can be explained considering that pharmacokinetic parameters result from a multiplicity of interactions with a variety of biological constituents that can be seen as fuzzy targets due to their fluctuating diversity. Moreover, a second difficulty is due to the heterogeneity of pharmacokinetic parameters, which, being obtained from complex biological systems, shows a decreased relatedness to molecular properties. These problems become apparent when examining correlations between lipophilicity and skin permeability for example, it was possible to derive parabolic equations with a significant predictive power when considering separately a homogeneous set of phenols and of nonsteroidal anti-inflammatory agents, but no correlation was obtained for the set of all...

Epidemiology and biology of colorectal cancer

Carcinomas of the colon and rectum are the second most common cause of death in the United States. Approximately 130,000 cases of colorectal carcinoma are diagnosed annually, and 56,000 patients will die of their disease (1). A number of genetic mutations detected in familial adenomatous polyposis and hereditary nonpolyposis cancer syndromes predispose individuals to a high and early risk of developing colorectal cancer, but the majority of cases are sporadic. A diet high in fiber and low in fat as well as regular use of nonsteroidal antiinflammatory agents appears to have a protective effect. Despite public health efforts at routine screening for colorectal disease, a substantial proportion of patients are diagnosed with advanced stage disease.

Does theophylline have a role in COPD management

There is increasing evidence that theophylline may have anti-inflammatory or immunomodulatory effects in asthma, and that these may be seen at lower doses than needed for bronchodilatation 5,6 (Fig. 11.1). The molecular basis for these effects is still uncertain, although some effects are mediated via a non-selective inhibition of phosphodiesterases (PDE) in inflammatory and immune cells. This has not yet been explored in COPD. In a recent study, theophylline (mean plasma level approximately 10mg L) was shown to decrease the proportion of neutrophils and the concentration of myeloperoxidase, an index of neutrophil activation, in induced sputum of patients with COPD 7 . This effect may be mediated by an inhibitory effect of theophylline on PDE4, the predominant PDE in neutrophils. However, the antiinflammatory effect of theophylline may be mediated by some other molecular mechanism, since the inhibitory effect on PDE activity is very small at these concentrations of theophylline....

The atheroprotective effects of highdensity lipoprotein cholesterol

While excessive mmLDL plays an important proinflammatory role in atherosclerosis, HDL and its associated apoA-I exert a corresponding cardiovascular benefit through the RCT pathway and several other important protective mechanisms.16 HDL also has beneficial antioxidant and anti-inflammatory properties and improves endothelial dysfunction. HDL contains two antioxidant enzymes, paraoxonase and platelet-activating factor (PAF) acetylhydrolase (PAFAH), that not only inhibit the oxidation of LDL but also help degrade oxidized phospholipids within oxLDL. HDL and its associated apoA-I protect endothelial cells from damage induced by oxLDL. HDL also displays anti-inflammatory properties, since pretreatment of human endothelial cells with HDL inhibits the cytokine-induced expression of cell adhesion molecules. Alternatively, overall HDL functionality may be more important than absolute HDLc levels, since recent data indicate that HDL has both proinflammatory and anti-inflammatory properties....

Natural Health Products

The active components of many natural health products (NHPs) are metabolized by similar pathways to modern medicines. It is therefore important to recognize whether NHPs are being taken, and specifically which ones, and to be aware of potential interactions. While many people appear to take NHPs safely, potential interactions have been identified 54 . For example, non-steroidal anti-inflammatory drugs (NSAIDs) have the potential to interact with herbs that have antiplatelet activity (e.g. gingko biloba, garlic, ginger, bilberry, dong quai, feverfew, meadowsweet, turmeric and willow) and with those containing coumadin (chamomile, motherworth, horse chestnut, fenugreek and red clover). The risk ofhepatotoxicity may be increased when acetaminophen is taken in conjunction with herbs such as kava. The use of sedative herbs such as chamomile, valerian, and kava may increase CNS depression due to opioid medications, and opioid effectiveness may be reduced by ginseng.

Immunological Properties of Glatiramer Acetate

As Th2 3-type cells secreting anti-inflammatory cytokines such as interleukin (IL)-4, IL10, and transforming growth factor (TGFb), but not Th1 cytokines, in response to both GAand MBP. Other myelin antigens such as PLP, MOG and ab crystalline could not activate the GATs cells to secrete Th2 cytokines. Yet the disease induced by PLP and MOG can be suppressed by these Ts cells, probably due to a bystander suppression mechanism.53'54 More recently, it has been demonstrated that these GA-specific Th2 suppressor T cells which were induced in the periphery by either injection or oral treatment accumulate in the brain.55,56 The GA-specific cells accumulated in the CNS demonstrated in situ extensive expression of the anti-inflammatory cytokines IL10 and TGFband the brain-derived neurotrophic factor (BDNF), but not the inflammatory cytokine IFN-g. Furthermore, the GA-induced cells infiltrating the brain induced bystander expression of IL10 and TGFb by resident astrocytes and microglia.57 These...

Murine Models of Atherosclerosis

Both LDLr_ _ and apoE _ _ models have been further exploited by backcrossing with other knockouts or transgenic mice overexpressing specific proteins to create new transgenic models that have helped define many of the mechanistic components underlying this disease. As a result, the specific effects of both human proinflammatory, anti-inflammatory, oxidative, antioxidant, and redox-regulated proteins on the atherosclerotic process have been confirmed in animal studies.

Immunological Effects of Glatiramer Acetate in Multiple Sclerosis Patients 814421 Antibody response

GA binding to the relevant MHC leads to peripheral activation of the regulatory suppressor cells, which are activated by shared suppressive determinants between MBP and GA, to secrete Th2-suppressive cytokines. These GA-specific Th2 cross the blood-brain barrier. Local reactivation of these cells in the brain by MBP stimulates the release of anti-inflammatory cytokines which downregulate the autoaggressive response to MBP as well as to other myelin antigens (e.g., PLP and MOG), which are colocalized with MBP, due to bystander suppression (Figure 3). It is currently believed that Th2-regulatory Tcells play a major role in the mode of action of GA, and bystander suppression is a central element in it. In addition to the in situ release of anti-inflammatory cytokines, the GA-specific Th2 cells were also shown to release BDNF in the CNS, which may explain the neuroprotective effects recently attributed to GA.

Support of Energy Balance

Lived and associated with a number of adverse effects. Non-steroidal anti-inflammatory drugs (NSAIDs) have been shown to reduce the acute-phase protein response and REE and to preserve body fat by support of food intake in patients with advanced cancer on long-term treatment 24 (Fig. 6, 7). Thus, indomethacin stabilised performance status and prolonged survival in a number of cancer patients 31 . Therefore, anti-inflammatory

Infections Transmitted Through the Respiratory Route

Respiratory tract infections are common, usually mild, and self-limiting, although they may require symptomatic treatment with paracetamol or a nonsteroidal antiinflammatory. These include the common cold (80 rhi-noviruses and 20 coronaviruses), adenoviruses, influenza, parainfluenza, and, during the summer and early autumn, enteroviruses. Special attention should be given to detainees with asthma or the who are immunocompromised, because infection in these people may be more serious particularly if the lower respiratory tract is involved.

Oral 5lipoxygenaseactivating protein inhibitors

An oral small molecule inhibitor of 5-lipoxygenase-activating protein (FLAP), DG-031, of unknown structure, is in clinical trials with CHD patients. FLAP inhibitors are anticipated to reduce proinflammatory leukotriene mediators such as the potent chemotactic agent, LTB4 (Figure 6). In a 4-week phase II trial in patients with a previous history of MI, DG-031 (250, 500, and 750 mg day 1 p.o.) at the highest dose reduced serum LTB4 (26 ) and MPO (12 ) levels as well as soluble intercellular adhesion molecule. As discussed previously, MPO and LTB4 are inflammatory markers associated with a higher risk of CHD. Plasma CRP levels were also reduced at the highest dose, but the response did not reach statistical significance. Accompanying these changes, LDLc levels increased slightly, by 8 with the highest dose.92 These results represent the first demonstration that two key biomarkers of inflammation were reduced following oral dosing with an anti-inflammatory agent in a CHD patient...

Chemokines And Cervical Cancer

The JE gene, a rodent homolog of human MCP-1, was initially isolated as an immediate-early gene, which can be stimulated at the level of initiation of transcription by the platelet-derived growth factor (75). Analyzing its transcriptional regulation in greater detail, it became clear that JE (MCP-1) expression can not only be induced by particular cytokines such as TNF-a (13,76), TGF-P (77), or IFN-y (76), but is also negatively controlled by antiinflammatory acting glucocorticoids (78) or even by hormones such as estrogen (79).

Inflammation and atherosclerosis

Despite important observations regarding an association between inflammation and atherosclerosis in the past, it has been only in the last two decades that scientists have specifically focused their attention on inflammation as a major player in the development of atherosclerosis. As reviewed recently by Ross 3 , the atherogenic process involves inflammatory mechanisms with pro- and anti-inflammatory cytokine production, and increased blood concentrations of acute phase reactants. Acute phase reactants, such as fibrinogen, C-reactive protein (CRP), serum amyloid A protein, syalic acid, caeruloplasmin and albumin, have been noted as markers of coronary disease activity, similar to other inflammatory disease processes. Typically, cells involved in chronic inflammation include macrophages, lymphocytes, mast cells and plasma cells. Different cell types, i.e. endothelial cells, vascular smooth muscle cells, macrophages and lymphocytes, as well as numerous families of cytokines and growth...

Pineal Gland and Cancer

The activity of pineal indoles on immune regulation suggests a major role for central nervous control of immune pathways 39-42 for example, melatonin has been reported to have anti-inflammatory effects 43, 44 . Indeed, pineal gland function may act on several levels in the pathways leading to cancer-associated anorexia-cachexia syndrome.

Administration of Melatonin in Cancer Associated Cachexia

Standard supportive care included nonsteroidal anti inflammatory drugs and opioid drugs for pain palliation. Steroids (dexamethasone or methylprednisolone) were administered in case of dyspnoea or hypotension (i.e. lung infiltration). Melatonin was administered per os daily in the evening, at 20 mg day. The dose was chosen empirically, based on the previous studies available at the time.

Methods to Induce Donor Specific Tolerance

Allograft rejection may be prevented by making the host tolerant to the alloantigens of the graft. Tolerance in this setting means that the host does not injure the graft despite the absence or withdrawal of immunosuppressive and anti-inflammatory agents. It is presumed that tolerance to an allograft will involve the same mechanisms that are involved in peripheral tolerance to self antigens (see Chapter 14), namely, anergy, deletion, and active suppression of alloreactive T cells. Tolerance is desirable in transplantation because it is alloantigen specific and will therefore avoid the major problems associated with nonspecific immunosuppression, namely, immune deficiency leading to increased susceptibility to infection and development of tumors and drug toxicity. In addition, achieving graft tolerance may reduce chronic rejection, which has to date been unaffected by the commonly used immunosuppressive agents that prevent and reverse acute rejection episodes.

Biologics for Use in Crohns Disease

There are a number of therapeutic targets for new biologics in CD (Fig. 12.4). Biologics aim to reduce muco-sal inflammation by inhibiting the effects of proinflam-matory cytokines interleukin (IL)-1 3, TNF, IFN-y, IL-12, IL-18 , by inducing apoptosis of type 1 helper lymphocytes (anti-IL-6, TNF antagonists), or by boosting natural anti-inflammatory mechanisms (granulocyte-macrophage colony-stimulating factor, transforming growth factor- 3, IL-20) (van Deventer 2003). Table 12.1 provides a list of approved and potential future biologic therapies for CD and key clinical trial data are summarized in Table 12.2.

Immunodeficiency After Bone Marrow Transplantation

* Graft rejection may be prevented or treated by immunosuppression of the host and by minimizing the immunogenicity of the graft (by limiting MHC allelic differences). Most immunosuppres-sion is directed at T cell responses and entails the use of cytotoxic drugs, specific immunosuppres-sive agents, or anti-T cell antibodies. A widely used immunosuppressive agent is cyclosporine, which blocks T cell antigen receptor signaling linked to cytokine synthesis. Immunosuppression is often combined with anti-inflammatory drugs such as corticosteroids that inhibit cytokine synthesis by macrophages and other cells.

COX2 Selective Inhibitors Celecoxib Rofecoxib and Valdecoxib

Notwithstanding their potential interest also in the treatment of cancer cachexia, some questions have arisen on the clinical use of these agents because of their toxicity and particularly cardiovascular risks. For this reason, rofecoxib has been withdrawn by the manufacturer. Another drug in this class, valdecoxib, has shown an increased risk for cardiovascular events in patients after heart surgery. As regards celecoxib, in December 2004 the National Cancer Institute stopped celecoxib (Celebrex) administration in an ongoing clinical trial investigating a new use of the drug to prevent colon polyps because of an increased risk of cardiovascular events in patients taking Celebrex versus those taking a placebo. Patients in the clinical trial taking 400 mg of Celebrex twice daily had a 3.4 times greater risk of cardiovascular events compared to placebo. For patients in the trial taking 200 mg of Celebrex twice daily, the risk was 2.5 times greater. The average duration of treatment in...

Management Approaches

Although not recommended by the EAU and AUA guidelines, phytotherapy has become a popular BPH treatment in parts of Europe. Recommendations from the 5th International Consultation on BPH regarding the use of plant extracts in the treatment of BPH suggest that every brand should be fully evaluated, and only extracts with proven clinical efficacy should be used.52 A lipido-sterolic extract of Serenoa repens (Saw palmetto) is one such option, and there is a growing database supporting the use of one form (LSESr Permixon), which is a complex mixture containing 90 free fatty acids and 7 esterified long-chain fatty acids, which mainly consists of oleic, lauric, myristic, and palmitic acid.53 In a recent meta-analysis of 14 randomized clinical trials involving over 4000 patients, with a maximum duration of 720 days, Permixon was associated with a mean decrease in IPSS of 4.78 and a mean improvement in Qmax of 1.02 mLs _ 1 above placebo.54 Although the exact mechanism of action is unknown,...

Atherogenesis And Atherosclerosis

Atherogenesis can begin early in life with EC activation (2). The pathological process is initiated by lipid deposition seen early in the subendothelial space with resultant inflammatory cell infiltration. In the presence of high circulating levels, LDL cholesterol is taken up by the endothelium. Passing through caveoli, LDL becomes trapped in the subendothelial extracellular space (3). This impairs the secretion of vasodilatory and anti-inflammatory factors, such as NO (4). The altered endothelium releases endothelin-1 (ET-1) and angiotensin II (ATII), which function as vasoconstrictors. This leads to VSMC hypertrophy and vascular remodeling (5,6). Circulating monocytes expressing type A scavenger receptors, which recognize acetylated LDL molecules, transmigrate through the endothelium to engulf the lipids within the subendothelial space. Monocytes differentiate into activated macrophages expressing higher levels of SR-A (7), CD 32 (8), SR-BI (9), CD68 (10), and the...

Ocular pathologies in animals and available drugs4244

Ocular inflammation is one of the most common eye disorders in animals.45 The precise observation and interpretation of signs provides the basis for diagnosing the disease and its associated disorders, and for establishing their etiology (trauma, lid or lacrimal abnormalities, viral or bacterial infection, immune-related phenomena, corneal ulceration). Topical steroidal therapy in combination with non steroidal anti-inflammatory drugs, immunosuppressive agents such cyclosporine and azathiopr-ine, antimicrobial agents, mydriatic-cycloplegic agents (atropine) and additional specific therapies are frequently prescribed to treat conjunctivitis, keratitis and uveitis (Table l).46,47 Topically applied steroids are in most cases used in combination with an antimicrobial agent. The reason is probably that the concomitant administration of steroid can increase the efficacy of antibiotics.48 In addition, this association prevents a secondary infection that may occur after a corticosteroid...

Mechanisms of Renal Dysfunction

Inflammation is an important contributor to the renal injury and endothelial dysfunction observed in hypertension and obesity. Elevated circulating levels of IL6 and TNF-a are observed in obesity and metabolic syndrome patients. IL6 stimulates the central and the sympathetic nervous system, which may result in hypertension.30 IL6 induces increases in hepatic triglyceride secretion in rats. IL6 also stimulates the production of C-reactive protein in liver and plasma levels of this protein are a good predictor of vascular inflammation. Another cytokine linked to obesity is TNF-a. TNF-a is overexpressed in the adipose tissue of obese patients, as compared with tissues from lean individuals. A positive correlation has been found between serum TNF-a concentration and both systolic blood pressure and insulin resistance in subjects with a wide range of adiposity. TNF- a acutely raises serum triglyceride levels in vivo by stimulating very low-density lipoprotein (VLDL) production and hence it...

Lymphedema of the

Secondary lymphedema develop in cancer patients after surgical interventions and radiation therapy. Due to removal of lymph nodes and diminished functioning of the lymphatic passages excess lymph accumulates in the affected extremity. The diminished oxygen supply may trigger the invasion of polymorphous neutrophilic leukocytes and the production of reactive oxygen radical species, resulting in inflammatory reactions and ultimately progressive degenerative changes in the affected extremity. The administration of sodium selenite (selenase), in some cases even after single oral dose of 800 g selenium, causes spontaneous volume reductions of the affected extremity and has anti-inflammatory effects selenite supplementation in addition diminished the serum levels of 2-hydroxynonenal and malondialdehyde, two parameters of lipid peroxidation (78-80). Selenite in addition increased the contractility of the lymphatic vessels, improved the effect of manual de-congestion therapies by about 15...

The Role Of The Immune System In Promoting Tumor Growth

Angiogenesis, and matrix metalloproteinases, which modify the extracellular tissue. Therefore, chronic activation of some innate immune cells is characterized by angiogenesis and tissue remodeling, which favor tumor formation and spread. Innate immune cells may also contribute to malignant transformation of cells by generating free radicals that cause DNA damage and lead to mutations in tumor suppressor genes and oncogenes. Some data suggest that cells of the innate immune system, including mast cells, neutrophils, and macrophages, secrete soluble factors that promote cell cycle progression and survival of tumor cells. The transcription factor NF-kB, which is a key mediator of innate immune responses, may play an important role in inflammation-associated cancer progression. The adaptive immune system can promote chronic activation of innate immune cells in several ways, including T cell-mediated activation of macrophages in the setting of persistent intracellular microbial infections...

Anabolic Androgenic Steroids and Other Anabolic Steroids

Anabolic steroids are analogues of testosterone that can increase lean body mass 107, 108 and increase weight and activity in hypogonadal males 109, 110 . Although a proportion of cancer patients may be hypogonadal 111 , the role of these drugs and how they should be combined with other modalities (e.g. physical therapy, nutrition and anti-inflammatory anti-catabolic therapies) in cancer cachexia is currently unclear. As with other anabolic agents there has been some concern that tumour growth may be promoted. There has also been wariness of potential toxicity. Once again, present data can lend support to opposing points of view. In two contemporary studies, oxandrolone was reported to improve weight, lean body mass, performance status and

Adverse Reactions in Highly Efficacious Antia4Integrin Therapy with Natalizumab

Until now there is no clear explanation of how exposure to natalizumab might favor PML. PML is a rare disease, caused by the JC virus, which is typically present in 80 of the healthy human population. Disease usually develops when the immune system is suppressed, either by HIV infection or cytotoxic chemotherapy. The initial hypothesis was that natalizumab suppresses effective immunosurveillance of the brain, considering the powerful anti-inflammatory effects of natalizumab. It should be noted, however, that blockade of VLA-4 also exerts widespread effects in the hematopoietic system. VLA-4 is required for mobilizing T cells and B cells from bone marrow, and these effects on bone marrow may be directly relevant for subsequent development of PML (Ransohoff 2005). During natalizumab treatment, JC-virus-infected bone marrow cells could be mobilized, and finally lead to JC infection of the brain. It is of note that all three cases of PML either had a combination therapy with...
