Filter by:Painful bladder syndrome (PBS)/interstitial cystitis (IC) may be due to the actions of nitric oxide (NO) in the bladder tissue. NO is a gaseous substance with a very short half-life, synthesized by a group of NO-synthase-enzymes in many tissues. The goal of this study is to illuminate bladder tissue production of NO in individuals with PBS and healthy individuals, by quantification of NO and NO-enzyme expression by different molecular biological methods.
EPIC is a case/control study that seeks to identify the risk factors for interstitial cystitis by comparing the experiences and medical histories of 400 women who recently developed IC with 400 similar people who do not have the disease.
The cause of interstitial cystitis is unknown. However, it tends to run in some families suggesting that there may be a genetic susceptibility to the disease. For instance, the disease is found 17 times more commonly in first-degree relatives (parent, sibling, or child) of patients with interstitial cystitis than in the general population. Furthermore, if one twin has interstitial cystitis, the disease is much more common in identical co-twins than fraternal co-twins. This evidence suggests that, in some families, genes that make a person susceptible to interstitial cystitis are being passed from one generation to the next. The University of Maryland School of Medicine and the National Institutes of Health are performing a study to identify these genes for susceptibility for interstitial cystitis. This study is entitled the Maryland Genetics of Interstitial Cystitis (MaGIC) study. The MaGIC study will investigate several hundred families with two or more blood relatives with interstitial cystitis. The study will seek to find changes in genes that are found far more commonly in family members who have interstitial cystitis than in those who do not have the disease.Identifying these genes should lead to a better understanding of the cause of interstitial cystitis. Finding the cause is the first step to finding the cure. This is a national study which is conducted by telephone and mail, and in which you can participate entirely from your home.
Patients with interstitial cystitis have been well documented to have pelvic floor muscle tenderness as well as pain on bladder distension. Some investigators have even suggested that pelvic floor muscle pain is primarily the cause of bladder problems. Botulinum toxin A causes muscle relaxation by inhibiting the acetylcholine release at the neuromuscular junction. It has been shown that this mechanism relieves pain in a number of muscle spasm-related syndromes. Because, at present, there is little effective therapy available for patients with interstitial cystitis, the researchers want to determine if botulinum toxin A will relieve bladder and pelvic pain in these patients.
This protocol describes a multi-centre, community based open label study designed to assess the efficacy and safety of intravesical sodium chrondroitin sulfate (Uracyst®) in the treatment of patients with a clinical diagnosis of interstitial cystitis (IC). The safety of the study product will be evaluated through the incidence of adverse events and from results of physical examinations and laboratory tests.
This is a randomized clinical trial study to test the efficacy and safety of amitriptyline in the treatment of patients newly diagnosed with painful bladder syndrome (PBS). PBS is defined by symptoms--frequent urination day and night and increasing pain as the bladder fills--according to the International Continence Society. The syndrome includes interstitial cystitis (IC), which has been estimated to affect as many as 700,000 people, mostly women. Estimates for PBS vary widely, but as many as 10 million people may suffer from this condition. Although amitriptyline is a Food and Drug Administration (FDA)-approved medication used for depression, the way it works makes it useful for treating the pain of fibromyalgia, multiple sclerosis, and other chronic pain syndromes. Prior small studies in interstitial cystitis (IC) suggested the drug may be a wise choice for this syndrome as well, because it blocks nerve signals that trigger pain and may also decrease muscle spasms in the bladder, helping to relieve the symptoms of pain and frequent urination.
Acupuncture is a form of Chinese medicine that has been in existence for more than a thousand years. This clinical trial performs two types of acupuncture on traditional 'bladder' points to determine if one type demonstrates improvement over the other. In the first type needles stimulate acupuncture points on the skin, and in the second type the needles penetrate through the skin similar to how acupuncture is usually performed. The technique is done through shields so that people will not know what type of acupuncture they receive. Patients must have at least moderately severe disease as determined by a urologist. They must be willing not to change their medical regimen for the duration of the trial. Patients will receive twelve treatments over six to twelve weeks. They will be asked to fill out symptom questionnaires and bladder diaries at regular intervals to monitor change. All treatment is free of charge, and patients who complete the trial will receive a small stipend.
The purpose of this study is to evaluate the safety and effectiveness of pentosan polysulfate sodium 100 mg once a day, pentosan polysulfate sodium 100 mg three times a day, and placebo for 24 weeks for the relief of bladder pain or discomfort associated with interstitial cystitis.
Patients with interstitial cystitis who meet eligibility requirements will be randomized to one of four treatment arms (3 RTX, Placebo). Study drug is administered as a single instillation within the urinary bladder. Study duration is 12 weeks.
OBJECTIVES: I. Estimate the optimal safe dose of intravesical capsaicin in patients with interstitial cystitis. II. Evaluate the efficacy of 0.025% topical capsaicin in relieving chronic burning pain in patients with vulvar vestibulitis. III. Evaluate the effect of capsaicin on type C nerve fibers in bladder mucosa and vulvar skin. IV. Evaluate the effect of C fiber depletion on urinary levels of histamine and prostaglandin.
