ORWH:SCOR - Sex/Gender Factors Affecting Women's Health Clinical Trials Information presented on Clinical Trials Search is not designed to be a substitute for certified medical advice, trips or professional assistance with a real medical doctor. We aren't docs. Always confer with your doctor about ORWH:SCOR - Sex/Gender Factors Affecting Women's Health conditions. Clinical Trials Search.org is a website committed to listing clinical research studies in human subjects. ORWH:SCOR - Sex/Gender Factors Affecting Women's Health Clinical research trials and ORWH:SCOR - Sex/Gender Factors Affecting Women's Health health trials happen in many of cities across the US. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally measure the effectualness of new does drugs. The intention of the studies / projects is to figure out particular human healthcare questions. Clinical trials are a popular manner for doctors, government agencies, and private sector corporations to detect cures for all forms of circumstances, like ORWH:SCOR - Sex/Gender Factors Affecting Women's Health. ORWH:SCOR - Sex/Gender Factors Affecting Women's Health Clinical Trials and other clinical trials allow for volunteers to undergo medical treatment options before they are available to the general public. Most times the subjects get treatment for free of charge, and occasionally they are paid for their time. Occasionally there is a cost for a ORWH:SCOR - Sex/Gender Factors Affecting Women's Health clinical trial. Subjects frequently get the best healthcare possible for their ORWH:SCOR - Sex/Gender Factors Affecting Women's Health condition. Hazards are a reality, however, and could include more or frequent mD visits, health risks (possibly life-jeopardizing), and/or the treatment being ineffectual. Trials are federally regulated with exacting guidelines to protect clinical trials patients.

ORWH:SCOR - Sex/Gender Factors Affecting Women's Health
For Condition: Urinary Tract Infection
Status: Recruiting
Sponsor(s): National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) ,
Synopsis: This project is the clinical project of a Specialized Center of Research (SCOR) proposal which is designed to further our understanding of urinary tract infection (UTI) in women. Acute uncomplicated urinary tract infections (UTIs) occur in an estimated 7-11 million women each year, and the annual costs of caring for these women are thought to approach $1.6 billion. Approximately 20-30% of women suffer from frequent recurrent infections. UTIs in young women result in substantial symptoms, time lost from work, and medical costs. An improved understanding of the mechanisms underlying UTIs could result in new approaches to their prevention and reduced numbers of women with infections and the amount of antibiotics use. In this project we seek a better understanding of the causes of UTI. Most experts believe that vaginal colonization with UTI-causing bacteria from the rectal flora precedes colonization of the urethra (the tube from the bladder for urination) and bladder and subsequent UTI, but the relationships between these events has not been established. Moreover, recent information from studies in mice strongly suggest that persistent bladder infection follows an initial bladder infection. In this project, we will prospectively follow a large group of women with recurrent UTI to determine: 1) the relationships in time between vaginal colonization with a UTI-causing bacteriuria, asymptomatic bacteriuria (bacteria in the bladder but without any UTI symptoms) and symptomatic UTI, and 2) the presence of persistent bacteria in the bladder following the symptomatic UTI at entry into the study and whether such bacteria are related to later UTIs that are caused by the same bacteria that caused the UTI at entry into the study. We will thus be able to determine the relative importance of vaginal colonization vs. persistent infection of the bladder as the origin of the bacteria causing recurrent UTI. UTI-causing bacteria cultured from women with symptomatic UTI and asymptomatic bacteriuria will undergo studies by Dr. Scott Hultgren's group at Washington University in Project 1 to identify unique genes that may help us understand why some bacteria cause symptoms and others do not. The effect of bacteria causing UTI in these women on host response will also be determined by studies by Dr. Jeff Gordon's laboratory at Washington University in Project 3. A better understanding of the molecular and epidemiologic basis of UTI is critical in developing the best possible prevention and management strategies.
