Cranberry and Other Herbal Therapies for Urinary Tract Infections

Cranberry juice is of relevance because urinary tract infections (UTIs) are common with MS, and cranberry juice has a long history of use in their prevention and treatment. From the 1920s to the 1970s, it was believed that the acid from cranberry juice makes the urine acidic and that this increase in acidity prevents and treats UTIs. However, subsequent studies showed that the effect of cranberry juice was probably due to the presence of two types of compounds, fructose and a class of chemicals known as proanthocyani-dins. These chemicals do not destroy bacteria. Instead, they appear to keep bacteria from attaching to the walls of the urinary tract. As a result, it is believed that bacteria present in the urinary tract are unable to cause an infection and are simply passed in the urine. In addition to these effects, cranberry juice, like antibiotic medications, also may kill some bacteria. Limited clinical studies indicate that cranberry may prevent UTIs in some people. A beneficial...

Hemorrhagic Cystitis

Hemorrhagic cystitis after transplant may be caused by cyclophosphamide or ifosfamide. The nonenzymatic metabolite of these agents, acrolein, causes hyperemia and ulceration of the bladder mucosa, resulting in hemorrhage and focal necrosis. Previously treatment with busulfan appears to increase the risk of hemorrhagic cystitis.114 Prophylaxis includes hyperhydration with forced diuresis, bladder irrigation, or mesna. There is no clear preferred strategy. Randomized studies comparing one prophylactic strategy to another have had mixed results.115-119 BK polyoma virus is another cause of hemorrhagic cystitis.117'120-123 Several investigators have demonstrated the presence of BK viruria in patients undergoing transplant, not all of whom had hemorrhagic cystitis. Neither background viral reactivation nor urothelial damage explain the increase in BK viruria in patients with hemorrhagic cystitis. This data was corroborated by Bogdonovic and colleagues, who also found that the risk of...

Psychophysical Studies Of Visceral Sensation

Psychophysical studies have demonstrated evidence of hypersensitivity to visceral stimuli in virtually all clinically relevant visceral pain disorders. This includes hypersensitivity to gastric distension in patients with functional dyspepsia (21), intestinal and rectal distension in patients with irritable bowel syndrome (7,22), biliary and or pancreatic duct distension in patients with postcholecystectomy syndrome or chronic pancreatitis (23), and bladder distension in patients with interstitial cystitis (17). In all cases, pain and or discomfort were experienced at intensities of stimulation lower than required to produce the same quality and intensity of sensation in a healthy population. It is notable that in many cases, the hyper-sensitivity was limited to the particular organ system being studied. An example of this was reported by Aspiroz (24), who observed hypersensitivity to gastric distension but normal sensitivity in the duodenum and upon cutaneous testing in subjects with...

Camptothecins as antitumor agents

Camptothecin is a plant alkaloid obtained from the Camptotheca acuminata tree. It was first evaluated clinically, as a sodium salt, in the 1960s and 1970s, but was abandoned because of severe and unpredictable hemorrhagic cystitis (3,4). Irinotecan (CPT-11) and Rubetecan are semisynthetic, water-soluble derivatives of camptothecin possessing

The Discovery of NFormimidoyl Thienamycin Imipenem a Stable Molecule with a Superior Profile as an Inhibitor of

At this juncture another totally unexpected problem arose. It was discovered that imipenem and thienamycin are metabolized rapidly in vivo in several mammalian species. The metabolic degradation was found to occur in the kidney. Scientists working with beta lactam antibiotics expect to find metabolism by bacterial enzymes. The Merck team was now confronted by the ironic fact that an antibiotic stable to bacterial beta lactamases is rapidly inactivated by a mammalian enzyme bound to kidney membranes, known as dehydropeptidase I. Going forward with imipenem would mean that the new Merck antibiotic would not be useful in the treatment of urinary infections.

Clinical Implications

The concentration of such nociceptive channels may also allow targeted inhibition or even destruction of nerves triggering abnormal activity. This strategy is used successfully in patients with interstitial cystitis, where instillation of capsaicin or resifineratoxin, both activators of the TRPV1 channel, improve symptoms associated with a transient decrease in the density of nerve fibers within the bladder wall.

Peripheral Sensitization And Visceral Pain Syndromes

The current understanding of mechanisms of peripheral sensitization is largely derived from studies examining the effects of injury or inflammation on visceral afferents. Most patients with chronic visceral pain, such as irritable bowel syndrome, nonulcer dyspepsia or interstitial cystitis, do not have signs of inflammation, raising questions about the relevance of these findings. While the definition of such functional diseases excludes active inflammation, up

Presenting Signs and Symptoms

The most common presenting signs and symptoms of an ovarian tumor are abdominal pain, palpable abdominal mass, increasing abdominal girth, urinary frequency, constipation and dysuria 10, 28 . Some tumors, however, are asymptomatic and only discovered during routine examinations. Abdominal pain is most often chronic, but torsion of the ovary can be associated with acute pain. Since normal sex cord-stromal cells are involved in steroid hormone produc

Urinary Bladder Cancer

Smoking is the greatest risk factor and is estimated to be a causative factor in 65 of males and 30 females in some developed countries. Historically, some types of bladder cancer were associated with abuse of analgesic combinations containing phenacetin and occupational exposure in the aniline dye industry (e.g., exposure to 2-naphthylamine). In Egypt and some other African nations, chronic bladder infections with Shistosoma haematodium are a risk factor.

Joseph B Muhlestein MD

Chronic infection has been found to be significantly associated with the development of atherosclerosis and the clinical complications of unstable angina, myocardial infarction, and stroke. A variety of infectious agents have been proposed to be involved in atherothrombosis, and, indeed, the number of implicated agents continues to increase each year. These include specific bacterial and viral agents, as well as a variety of agents associated with periodontal disease. However, failure to confirm initial reports of serological associations also has been common. The infectious agents with the most evidence to support an etiological role in atherosclerosis include Chlamydia pneumoniae and cytomegalovirus. In addition, evidence is mounting for a variety of other potential agents including other herpes viruses, influenza, other specific bacteria (such as Mycoplasma pneumoniae), and chronic infections with common bacterial agents (e.g., periodontal disease, chronic bronchitis, chronic...

Clinical Presentations and Diagnosis

Diagnosis of these tumors in this age group is challenging. The classic triad of local symptoms of the primary malignant tumor - bleeding, a mass and pain -may be absent or appear late. Metastatic disease may present with local symptoms from metastatic sites or with generalized symptoms of weight loss, cachexia, fevers, and sweats. Symptoms are thus non-specific and clinical examination is relatively insensitive at detecting a small tumor and, in view of the rarity of a malignant diagnosis in this age group, clinical examination may not be appropriately directed. The differential diagnosis is likely to be dominated by non-malignant conditions. Inevitably this contributes to a delay in diagnosis for many patients. For example, hematuria in this age group is usually due to urinary tract infection. In older patients, in whom malignant disease is more likely, hematuria is routinely a trigger for full investigation to exclude malignant disease by imaging, cytology, and endoscopy. However,...

Diagnosis Symptoms and clinical Signs

Most common symptom is vague, usually generalized abdominal pain 18, 26, 29, 35, 36 . Localizing abdominal pain is usually an indication of peritoneal involvement or perforation. This pain is occasionally suggestive of appendicitis 35, 37, 38 . Weight loss is relatively common according to our recent review of St. Jude patients in which approximately two-thirds noted weight loss median loss 20 lbs (9.1 kg) range 5-81 lbs (2.3-36.8 kg) 39 . Other less frequent associated symptoms include nausea, vomiting, constipation, diarrhea, pallor, anorexia, rectal bleeding, abdominal distension, dysuria, and intestinal obstruction 18, 26, 29 . In one review of 29 patients, 13 presented acutely whereas 16 had more chronic symptomatology 29 . In our experience, the duration of symptoms before diagnosis has ranged from 3 days to 12 months, with a median of 2 months 18 . A mass or fullness may or may not be palpable on physical exam 26, 35, 37 . Primary tumors of the right colon usually present with...

Sex Differences in Brain Responses to Visceral Stimuli

A series of observations demonstrates that women are more likely to suffer from IBS, develop the so-called postinfectious IBS, and develop comorbidities such as fibromyalgia or interstitial cystitis (72). A variety of mechanisms have been proposed to explain these sex differences, including differences in the response of the central nervous system to pelvic visceral stimuli. Several investigators have addressed this question using functional brain imaging.

Differential Diagnosis

UTI, constipation, and comorbid psychiatric disorder, should be assessed and ruled out as appropriate (Figure 9-1). Other causes of nocturnal incontinence should be excluded, for example, those leading to poly-uria (diabetes mellitus, renal disease, diabetes insip-idus) and, rarely, nocturnal epilepsy.

Treatment Of Diurnal Enuresis

Daytime enuresis, although it can occur together with nighttime enuresis, has a different pattern of associations, and responds to different methods of treatment. It is much more likely to be associated with urinary tract abnormalities, including UTI, and to be comorbid with other psychiatric disorders. As a result, a more detailed and focused medical and psychiatric evaluation is indicated. Urine should be checked repeatedly for infection, and the threshold for ordering ultrasonographical visualization of the urological system should be low. The history may make it apparent that the daytime wetting is situation specific. For example, school-based enuresis in a child who is too timid to ask to use the bathroom could be alleviated by the teacher tactfully reminding the child to go to the bathroom at regular intervals.

Functional Gut Disorders

More than half of the patients in a gastroenterological clinic complain of abdominal symptoms, without demonstrable cause by conventional diagnostic tests. In the absence of positive findings, unexplained abdominal symptoms have been categorized as functional gastrointestinal disorders, and several syndromes, such as noncardiac chest pain, functional dyspepsia, and the irritable bowel syndrome (IBS), have been defined. Non-cardiac chest pain refers to patients with thoracic symptoms without cardiac, pulmonary, or esophageal disorders. Functional dyspepsia applies to symptoms such as epigastric pain, pressure, fullness, and bloating that presumably originate from the upper gastrointestinal tract, and that are frequently precipitated by meals. The IBS is attributable to the distal gut, and is characterized by abdominal pain or discomfort associated to disordered bowel habit. The diagnosis of those syndromes is solely based on clinical criteria, because their underlying pathophysiology...

Evaluation Of Mothers

GBS may be the cause of significant morbidity and mortality among pregnant women. In addition to urinary tract infections (UTIs), women may have chorioamnionitis, postpartum wound infection, bacteremia, or puerperal sepsis. Any pregnant mother with symptoms of a UTI should have a urine culture done, and the culture should be labeled as that of a pregnant woman. Because GBS bacteriuria is considered evidence of heavy colonization in the pregnant woman, any quantity of GBS in the urine of a pregnant woman should be reported by the laboratory to the obstetrician (19). Women who are symptomatic should be treated with standard therapy for the UTI. Whether a woman is symptomatic or asymptomatic, intrapartum antibiotics are recommended during labor for women who have bacteriuria (19). If a wound infection is suspected, cultures of the wound and blood should be obtained, and blood cultures are indicated in women with signs of bacteremia or sepsis. The diagnosis of chorioamnionitis is usually...

Other Prostatitic Conditions Causing Incontinence

There is evidence to suggest that prostatitis may be pathologically linked to interstitial cystitis in men as both of these conditions share common symptoms. In a survey of 92 men with interstitial cystitis confirmed by the National Institute for Diabetes and Digestive and Kidney Diseases criteria, the most commonly reported initial symptoms were mild suprapubic discomfort (33 ), nocturia (15 ), urgency (15 ), dysuria (11 ), and frequency (11 ) however, after 2.5 years these symptoms had become more severe and 89 reported dysuria, 85 had urinary frequency, 82 had severe suprapubic discomfort and or urgency, and 56 had sexual dysfunction.67 The overlap between prostatitis and interstitial cystitis has led researchers to consider that they have underlying causes. In a recent study of 50 patients with prostatitis, the majority of patients were also symptomatic on an interstitial cystitis questionnaire known as the pelvic pain and urgency frequency questionnaire, and 77 with a score more...

Chemotherapy Plus Growth Factors For Stem Cell Mobilization

While high-dose CY followed by GM-CSF or G-CSF is the most frequently chemotherapy growth factor mobilization regimen, it has several limitations, including potential cardiotoxicity, hemorrhagic cystitis, nausea, and vomiting. Several investigators have reported the effectiveness of high-dose etoposide (2 g m2) with GM-CSF or G-CSF as a mobilizing strategy.40 It is associated with minimal nonhematologic toxicity and has antitumor activity. Several other combination chemotherapy regimens are also effective for stem cell mobilization. Studies suggest that the combination of CY + etoposide, or CY + Taxol or CY+ etoposide + cisplatin are more effective than CY alone. The dose and type of growth factor utilized with chemotherapy may also be important. Although GM-CSF was the first cytokine to enhance PBSC mobilization by chemotherapy, it is now less commonly used than G-CSF, probably because of side effects such as fever and hypoxemia. The dose of G-CSF used with chemotherapy is lower than...

Possibly Effective CAM Therapies

People with recurrent UTIs should undergo a medical evaluation because it is important to determine the underlying cause. A CAM approach may be reasonable in some situations and should be discussed with a physician. Cranberry juice may be effective for preventing UTIs and is of low risk. Its effectiveness relative to the conventional approach with prescription antibiotics has not been investigated. Conventional treatment with antibiotics should be used to treat UTIs, because the effectiveness of CAM approaches for treating UTIs, including cranberry juice, is not established. Also, people with MS and UTIs should attempt to eliminate the infection as quickly as possible, because the infection may worsen neurological symptoms.

Predisposing Factors In Fetal And Neonatal Infection

Despite its presence in 25 of all pregnant women, isolation of Candida from the placenta is rare (12,13). Baley reported an incidence of less than 1 (14). In the presence of chorioamnionitis, fetal infection can occur and presents as congenital cutaneous candidiasis (CCC). Risk factors for congenital infection include early preterm birth, the presence of a foreign body such as an intrauterine device or cervical sutures, and possibly diagnostic amniocentesis (6,12). Factors that do not appear to play a role in congenital candidiasis are maternal age, prolonged rupture of membranes, diabetes, urinary tract infection, parity, and antibiotic, tocolytic, or corticosteroid therapy (15). The role of congenital candidiasis in precipitating preterm labor or premature rupture of membranes remains unknown and warrants further investigation (16,17).

Prenatal Evaluation

Any pregnant woman with a vaginal discharge or inflamed vulvovaginal area should be evaluated for Candida. Candida vulvovaginitis is the second most common cause of vaginitis after bacterial vaginosis. Many women are asymptomatic, but the classic signs are a profuse, pruritic, thick, white, curdlike discharge associated with dysuria, dys-pareunia, and pruritus ani. The diagnosis of Candida vulvovaginitis is a clinical diagnosis that is confirmed by culture and microscopic detection of the yeast. A drop of the cervicovaginal fluid should be immersed in a 10 potassium hydroxide (KOH) preparation on a glass slide with a coverslip for microscopic examination. Sometimes, this

Bradykinin Receptors

Postinfection hypersensitivity to jejunal distension (66). Interstitial cystitis is associated with enhanced levels of bradykinin in the urine (67), and experimental cystitis leads to upregulation of B l and B2 receptors in the urothelium (68). A role of bradykinin in the pathophysiology of cystitis can be concluded from the findings that the hyperreflexia of the detrusor muscle caused by experimental cystitis is reduced by both Bj and B2 receptor antagonists, Bj receptor antagonists having an effect only after inflammation has set in (68-70).

Ionotropic Purinoceptors

Acidosis (87,97), and (iii) P2X receptors on sensory neurons are upregulated by experimental inflammation (98). Likewise, interstitial cystitis leads to an increased expression of P2X2 and P2X3 protein in the urothelium (99), and inflammatory bowel disease is associated with an increased number of P2X3 receptors in the colon (100). Pharmacologic evidence points to a role of P2X receptors in abdominal chemonociception, since trinitrophenyl-ATP (a P2X1, P2X3, and P2X2 3 receptor blocker) and A-317491 (a non-nucleotide P2X3 and P2X2 3 receptor antagonist) suppress the nociceptive behavior provoked by intraperitoneal injection of acetic acid in mice (101,102). In contrast, the visceromotor pain response to colonic distension in the rat and the colitis-induced mechanical hyperalgesia are not attenuated by A-317491 (102). The further evaluation of the therapeutic potential of P2X3 and P2X2 3 receptors in acid-related, inflammation-, and ischemia-induced disturbances of gut sensation will...

Cannabinoid Receptors

It should not go unnoticed that there is some cross talk between cannabinoid receptors and TRPV1. Thus endocannabinoids such as anandamide can enhance TRPV1 activity via stimulation of protein kinase C (61). Vice versa, capsaicin-related compounds such as olvanil and arvanil, which are largely devoid of an excitatory influence on TRPV1, but induce a TRPV1-mediated state of sensory neuron refractoriness, are known to bind to CB1 receptors (297). The ability of endocannabinoids to enhance TRPV1 activity may be the reason that under conditions of inflammation, endocannabinoids may actually contribute to visceral hyperalgesia. Thus, cyclophosphamide-induced cystitis enhances the anandamide content of the urinary bladder, which goes in parallel with the development of bladder hyperreflexia (301). The effect of anandamide to induce reflex hyperactivity in the bladder is prevented by the TRPV1 blocker capsazepine (301). In another study, it has been found, however, that anandamide prevents...

Patients with Kidney Disease Secondary to Obstructed Outflow of Urine Interstitial Nephritis

Ernie Ball is a computer systems analyst. When he was 38, he visited his doctor because he had pain in his flanks. A urine test showed protein plus red cells, and his doctor told him that he had a urinary tract infection and urethral stricture. Leg swelling appeared soon thereafter. He had taken analgesics (aspirin or Anacin plus Dristan) daily for years because of headaches. By age 40, he had high blood pressure and signs of moderately severe kidney failure. At age 56, by which time his serum creatinine concentration was 6.4 mg per dl, indicating severe kidney failure, he started a supplemented very-low-protein diet. He succeeded in deferring dialysis for four more years by means of a very-low-protein, low-salt diet plus either amino acids or ketoacids, antihypertensive drugs, diuretics, calcium, zinc, iron, vitamins, and sodium polystyrene sulfonate.

Disease Basis

Hemolytic anemia, thyrotoxicosis, interstitial cystitis, and Sjogren's syndrome, and that this association resulted in a 45 increase in risk for schizophrenia. The antipsychotics used to treat schizophrenia can be divided into two distinct classes, typical and atypical. The distinction between the two can be based on their time of introduction to market, typicals preceding atypicals their receptor-binding profile, the atypicals antagonizing both D2 and 5HT2 receptors with additional binding to D3 and D4 receptors but most importantly, the ability, albeit limited, of the atypical neuroleptics to address the negative symptoms of schizophrenia together with a lower risk of developing the tardive dyskinesia associated with the older, typical antipsychotic agents. A more controversial distinction is that typical antipsychotics are neurotoxic while atypical agents are metabolic poisons.9

Vesicouretic reflux

Pizzini and colleagues 24 studied 38 children aged between 1 and 12 years with at least two episodes of urinary tract infection (UTI) six patients were subsequently shown to have reflux. The levels of urinary N-acetyl- -glucosaminidase and a -microglobulin were both found to be higher in children with reflux when compared with levels found in both healthy controls and children with UTI and no reflux. However, in other studies of younger babies - in whom reflux has not yet These statistics clearly identify the need for a marker to detect the early effects of reflux. Renal scarring occurs predominantly when the reflux has ascended well up into the nephrons and the ensuing inflammation affects both glomerular and tubular function. Thus, the diagnostic inaccuracies of previously studied markers are attributable to the fact that these tests predominantly reflect proximal tubular damage. The need exists for a marker to detect the effect of reflux on the collecting duct (or, less...

Toxicity

Most patients tolerate BCG well, but as with most cancer treatments, serious and even fatal toxicity can occur 55 . Irritative bladder symptoms including frequency and dysuria that typically begin after the second or third instillation and last for 1 or 2 days are the result of immune stimulation and cytokine production. These

Human Carcinogens

Antibiotics Two main classes (1) the true anthracyclines daunorubicin, doxorubicin, and (2) the mycins adriamycin, bleomycin, mithramycin, mitomycin. Most antineoplastic antibiotics are derived from the Streptomyces bacterium and release oxygen (O-) free radicals (similar to paraquat), causing severe cardiotox-icity, parenchymal pulmonary toxicity, mucosi-tis, and myelosuppression. Alkylating agents Two main classes (1) nitrogen mustards, like cyclophosphamide and chlor-ambucil, can cause hemorrhagic cystitis and myelosuppression on overdose and (2) heavy metal platinoids, like cisplatin and carboplatin, can cause seizures, encephalopathy, retinal tox-icity, ototoxicity, and peripheral neuropathy on overdose. Hemorrhagic cystitis,

The Bladder

The most common form of bladder pain in the clinic is that caused by infection, resulting in cystitis, although overdistension of the bladder in acute urinary retention is also very painful. These two mechanisms have been employed in the design of rodent models of bladder pain, using direct distension of the bladder, or instillation of chemical or infectious agents. Environmental stressors have also been used, as stress is known to exacerbate symptoms in human disease. The induction of cystitis, using the prodrug cyclophosphamide, is a common model of choice for assessing bladder hyper-reflexia and hypersensitivity intraperitoneal cyclopho-sphamide administration results in the accumulation of its toxic metabolites (mostly acrolein) in the urine, which produce bladder irritation and inflammation. This model has the advantage that it does not require surgery, and appears to be similar to human visceral pain cyclo-phosphamide-induced cystitis in humans is also painful. The behavioral...

Prostate cancer

Patients may present with pelvic pain, dysuria, poor urinary stream, and possibly hematuria. Digital rectal examination may reveal clues to the diagnosis, but is relatively insensitive. Pelvic imaging by MRI, CT scan, or trans-rectal ultrasound may also sometimes miss a diffuse tumor of the prostate, and biopsy procedures

Lower abdominal pain

All sexually active women presenting with lower abdominal pain should be carefully evaluated for the presence of salpingitis and or endometritis-pelvic inflammatory disease (PID). In addition, routine bimanual and abdominal examinations should be carried out on all women with a presumptive STI, since some women with PID or endometritis will not complain of lower abdominal pain. Women with endometritis may present with complaints of vaginal discharge and or bleeding and or uterine tenderness on pelvic examination. Symptoms suggestive of PID include abdominal pain, dyspareunia, vaginal discharge, menometrorrhagia, dysuria, pain associated with menses, fever, and sometimes nausea and vomiting.

Animal Studies

Cyclophosphamide-induced cystitis in mice, in addition to behavioral signs of direct visceral pain (49), also produces referred hyperalgesia of the tail base, which is inhibited dose dependently by morphine (50). The murine models of visceral pain referred hyperalgesia from both the GI tract and the urinary tract are being increasingly used to investigate referred phenomena from viscera in genetic studies. As will be discussed in more detail in the sections devoted to pathophysiolo-gical mechanisms, transgenic mice that lack the receptor for substance P (NK1), for instance, fail to develop both primary hyperalgesia after visceral inflammation (intracolonic capsaicin or acetic acid, and cyclophosphamide cystitis) and referred hyperalgesia or tissue edema (55), while mice lacking the tetrodotoxin-resistant sodium channel alpha subunit Nav1.8 (which is expressed exclusively in primary sensory neurons) show weak pain and no referred hyperal-gesia to intracolonic capsaicin, a model in...

Oxazaphosphorines

The development of 12 would have been severely hampered in the current paradigm of drug discovery in that only compounds that are highly active (cytotoxic, antiproliferative, induce apoptosis, etc.) versus transformed cell lines in vitro are further progressed to in vivo xenograft murine models of cancer. Cyclophosphamide is only weakly cytotoxic versus transformed cells in vitro. Nevertheless, administration of 12 in vivo to either animals, or subjects with sensitive tumors, provides dramatic antineoplastic effects. The initial rationalization for the in vivo activity of 12 was based on phosphatase or phosphoamidase cleavage of the P-N bond, which would release the mustard group. This hypothesis has been subsequently proven incorrect (for a summary of the development of oxazaphosphorine-based agents see 23). The accepted mechanism for cyclophosphamide's impressive in vivo activity is shown in Figure 6. Upon administration of 12, metabolic activation occurs via the cytochrome P450...

Wound Healing

Cystitis Interstitial cystitis is characterized by prolonged pollakiuria and pain in the suprapubic region when the bladder is full of urine (48). For the treatment of interstitial cystitis, sulfated exogenous polysaccharides, sodium pentosanpoly-sulfate (49), DMSO (50), heparin (51) and other agents are used (52-54). Interstitial cystitis may be related to a primary defect in glycosaminoglycans (GAGs), i.e., HA, heparan sulfate, dermatan sulfate and keratan sulfate in the vesical mucosa (55). A GAG coating of the bladder urothelium may protect the bladder tissue from injury by stimulants, e.g., by microorganisms, crystals and other toxic substances (56). It has been reported that intravesical injection of HA is useful for interstitial cystitis (57,58). Intravesical HA has been used to treat interstitial cystitis, since this may possibly replenish bladder GAGs. Takahashi et al. (59) have evaluated the effect of 0.1-0.4 HA (average MW 890 X 103) on epithelial healing of the vesical...

Vitamin C

Vitamin C supplements are sometimes recommended for preventing or treating urinary tract infections (UTIs), which occur frequently in some women with MS. This recommendation is based on the idea that vitamin C, also known as ascorbic acid, makes the urine acidic and thus inhospitable for bacteria. However, there is no definitive evidence that the use of vitamin C supplements produces acidic urine or decreases the chance of developing a UTI. More evidence exists for cranberry juice (see the chapter on Herbs) than for vitamin C in preventing UTIs. If an actual infection is present, prescription antibiotics should definitely be used, because people with MS may have serious complications from UTIs.

Bladder

Cyclophosphamide and ifosfamide are both capable of inducing hemorrhagic cystitis as a result of accumulation of acrolein in the bladder 94 . Urgency, frequency, and dysuria are symptoms commonly associated with hemorrhagic cystitis, which can be a long-term complication of cancer therapy in some patients 95 . Radiation to the pelvis or bladder can result in fibrosis and scarring, with resultant decreased bladder capacity and predisposition to urinary tract infections 96 . Bladder cancer has developed in some patients who received bladder-toxic agents during treatment for cancer 94 . Yearly urinalysis should be done in these patients to evaluate for the presence of microscopic hematuria.

Microbiology

Lymphopenia appears to be a risk factor for progression to lower respiratory tract infection in HSCT recipients with influenza.21 Other pathogens, such as Aspergillus species, are frequently isolated in patients with influenza involving the lower respiratory tract. Antiviral therapy in HSCT recipients with influenza with a neuraminidase inhibitor is preferred to amanti-dine or rimantidine, as neuraminidase inhibitors appear to shorten the duration of viral shedding.21 Inhaled ribavirin and intravenous immunoglobulin have been...

Other CAM Therapies

Vitamin C is sometimes recommended for preventing and treating UTIs. However, studies do not indicate that vitamin C is effective, and it carries a theoretical risk in MS because of its immune-stimulating activity. Bearberry, or uva ursi, is also sometimes recommended for UTIs. The effectiveness and safety of this herb have not been established. In some studies, marijuana has

Tachykinin Receptors

Tachykinin receptor antagonists may target multiple relays in the nociceptive pathways from the periphery to the brain. One site of action is within the spinal cord where tachykini-nergic transmission from primary afferents is interrupted. This appears to be true for the antihyperalgesic effect of the NKX receptor antagonist TAK-637 in the rabbit and guinea pig (253,255). One study reports that the visceromotor pain response to colorectal distension in rats and the hypersensitivity caused by repeated distension is blocked by intrathecal administration of an NKX or NK3, but not NK2, receptor antagonist (260). In another study, it has been found that the inflammation-induced hypersensitivity to noxious colorectal distension in rats is inhibited by the intrathecal administration of an NK3 receptor antagonist or a combination of an NKX and NK2 receptor antagonist, whereas NKX and NK2 receptor antagonists given singly are without effect (261). These observations point to a site of action...

Opioids

Opioids constitute a major class of analgesic to treat visceral pain. Experimentally, within the types of pain discussed in this chapter, studies have focused on two sites of action for opioids, the periphery and the spinal cord. Systemic administration of m or k opioid receptor agonists attenuates responses to noxious stimulation of the colon, bladder, and uterine-cervix. Administration of naloxone methiodide, which does not cross the blood-brain barrier, indicates separate sites of action for m and k agonists. Systemic morphine attenuates the visceromotor response evoked by CRD of the inflamed and noninflamed colon (59,62,176-178), bladder (179,180), uterine-cervix distention (69,181,182), ureter (183) and stomach (184) as well as referred pain from colonic inflammation (43). Systemically administered m and k opioid receptor agonists attenuate Fos expression, dorsal horn neuronel activity, and the visceromotor response evoked by colorectal dis-tention in rats and mice...
