Genetic Analysis of Human Hypertensive End Stage Renal Disease (H-ESRD) Clinical Trials Info presented on Clinical Trials Search is not intended to be a substitute for certified medical advice, visits or professional assistance using a real physician. We are not physicians. Always consult your dr. about Genetic Analysis of Human Hypertensive End Stage Renal Disease (H-ESRD) conditions. Clinical Trials Search.org is a site dedicated to listing clinical research studies in human subjects. Genetic Analysis of Human Hypertensive End Stage Renal Disease (H-ESRD) Clinical research trials and Genetic Analysis of Human Hypertensive End Stage Renal Disease (H-ESRD) health trials happen in many of localities throughout the U.S.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials typically measure the effectualness of new drugs. The function of the studies / projects is to resolve particular human medical questions. Clinical trials are a popular manner for mDs, government agencies, and private sector corporations to discover remedies for all varieties of circumstances, like Genetic Analysis of Human Hypertensive End Stage Renal Disease (H-ESRD). Genetic Analysis of Human Hypertensive End Stage Renal Disease (H-ESRD) Clinical Trials and other clinical trials allow volunteers to obtain healthcare treatment options before they are available to the masses. Some times the participants undergo professional assistance for free of charge, and occasionally they are paid for their time. Sometimes there is a cost for a Genetic Analysis of Human Hypertensive End Stage Renal Disease (H-ESRD) clinical trial. Human subjects often get the best healthcare available for their Genetic Analysis of Human Hypertensive End Stage Renal Disease (H-ESRD) condition. Dangers are a reality, however, and may include additional or frequent mD visits, healthcare dangers (potentially life-jeopardising), and/or the treatment being ineffectual. Trials are federally governed with rigorous guidelines to protect clinical trials patients.

Genetic Analysis of Human Hypertensive End Stage Renal Disease (H-ESRD)
For Condition: Kidney Failure, Chronic,Heart Diseases,Hypertension,Cardiovascular Diseases
Status: Completed
Sponsor(s): National Heart, Lung, and Blood Institute (NHLBI) ,
Synopsis: To identify genes causing hypertensive end-stage renal disease (H-ESRD) in high risk African-American populations
Details: BACKGROUND: Although hypertension is a predisposing factor for end stage renal disease, the underlying hypothesis of this study was that in select African-American families genetic factors predisposed them to develop ESRD in the face of hypertension. An inherited basis for H-ESRD was supported by familial clustering of H-ESRD among African Americans that could not be explained by socioeconomic status, access to medical care, and the prevalence of diabetes and hypertension. DESIGN NARRATIVE: DNA samples were collected, identified, and clinically characterized from African-American sib-pairs (and other family members with hypertensive end-stage renal disease). This aspect of the study was based on the fact that Dr. Freedman, the principal investigator, had already developed a unique "family history of end-stage renal disease" database independently funded by the End-Stage Renal Disease Network Six. This registry served as a very large and unique collection of African-American end-stage renal disease patients. He began with a candidate gene approach for linkage to hypertensive end-stage renal disease in his patient samples using a variety of growth factor genes, genes involved in sodium transport and vascular tone, as well as human homologues of rodent genes that had, or were to be identified in the future as contributing to ESRD in that organism. If this initial first pass of candidate genes failed to demonstrate linkage to hypertensive end-stage renal disease, a systematic genome-wide scan was to be performed with available simple sequence length polymorphisms (SSLP) and other polymorphic markage. Hypertensive end-stage renal disease is a condition of enormous clinical and economic importance and identification of associated or causative renal-failure genes would form a genetic basis for the detection of high-risk individuals and assist in development of intervention and treatment strategies to prevent this condition.
