Randomized, multicenter, double-blind study to determine if renin angiotensin medications, either losartan (angiotensin II blocker) or enalapril (converting enzyme inhibitor), can prevent or delay the onset of diabetic kidney disease in patients with type 1 diabetic patients who do not have hypertension, diabetic nephropathy, or predictive levels of microalbuminuria. Two hundred eight five patients ages 16-61 with 2-20 yrs of Type 1 Diabetes Mellitus and no renal functional abnormalities were randomized into a parallel, double-blind, placebo-controlled study involving 3 groups (95 patients/group). Each group received an angiotensin-converting enzyme inhibitor (ACEI) (enalapril), or an angiotensin II receptor blocker (Losartan), or placebo. All patients had their usual Diabetes Mellitus (DM) management. Baseline studies included measures of glomerular filtration rate (GFR), urinary albumin excretion rate (UAE), blood pressure (BP), and a percutaneous renal biopsy. Patients were followed by quarterly measures of BP, HbA1C, UAE, and drug compliance. There were annual measures of GFR and a repeat renal biopsy after 5 yrs in the study. The main endpoint is kidney structural changes over time, especially mesangial fractional volume (v(Mes/glom)). Secondary endpoints will be other DN structural measures and measures of kidney function (UAE, GFR). These studies will determine whether rennin angiotensin system blockage in the early stages of DN can prevent the early kidney structural changes in this important disorder. Ancillary studies will evaluate the effects of treatment group on the development and progression of diabetic retinopathy and will develop predictors of study participants'''' compliance. Baseline, 2.5 and 5 year retinal fundus photographs in the RASS patients were obtained.

Clinical study that investigated several hundred families with two or more blood relatives with interstitial cystitis in order to understand the molecular genetic basis of this condition. The study sought 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. This is a national study which is conducted by telephone and mail, and in which participants could participate entirely from their home.

Publications from a multi-center, longitudinal, observational study examining the risk factors associated with the long-term complications of type 1 diabetes. The study began in 1994 and follows the 1441 participants previously enrolled in the Diabetes Control and Complications Trial (DCCT), http://diabetes.niddk.nih.gov/dm/pubs/control/index.aspx. The primary aim of EDIC is to examine the long-term effects of conventional vs. intensive diabetes treatment received during the DCCT on the subsequent development and progression of microvascular, neuropathic and cardiovascular complications. This involves studying the influence of genetic factors and other factors such as HbA1c, blood pressure, lipid levels, and treatment modalities on the development and progression of these complications. Annual or biennial measurements (using DCCT methods, standardized protocols and central laboratories) of vascular events, albumin excretion, GFR, ECG, ankle-brachial BP index, serum lipids and HbA1c allows the following analyses: 1) continuation of intention-to-treat analyses to determine long-term effects of prior separation of glycemic levels; 2) risk factors for macrovascular outcomes; 3) correlation of progression of micro- and macrovascular outcomes. The current updated version of the EDIC Protocol is available for download. EDIC is made up of 28 clinical centers, one data coordinating center and one clinical coordinating center.

Randomized, double blind, nationwide clinical trial to compare the efficacy and safety of three interventions to treat adolescents and youth with type 2 diabetes (T2D): (1) metformin alone, (2) metformin plus rosiglitazone, and (3) metformin plus an intensive lifestyle intervention called the TODAY Lifestyle Program (TLP). The secondary aims are to: compare and evaluate the safety of the three treatment arms; compare the effects of the three treatments on the pathophysiology of type 2 diabetes (T2D) with regards to beta cell function and insulin resistance, body composition, nutrition, physical activity and aerobic fitness, cardiovascular risk factors, microvascular complications, quality of life, and psychological outcomes; evaluate the influence of individual and family behaviors on treatment response; and compare the relative cost effectiveness of the three treatment arms. The study recruits patients over a three-year period and follows patients for a minimum of two years. Patients are randomized within two years of the diagnosis of T2D. Materials that were used for the study are made publicly available: * The TODAY Standard Diabetes Education (TSDE) program, developed especially for youth with type 2 diabetes. (All participants received the TSDE program) * The TODAY Lifestyle Program (TLP) that was among the treatments tested.

Data set and biosepecimens of a multi-center clinical trial to determine if treatment with beta-cell antigens can delay the onset of Type 1 Diabetes Mellitus (Type 1 DM) in non-diabetic relatives of persons with Type 1 DM. Insulin is a well characterized antigen specifically produced by beta-cells, and it was used for this purpose in the initial DPT-1 studies. The protocol for high risk subjects uses daily subcutaneous insulin injections and an annual course of intravenous insulin treatment, while the protocol for intermediate risk subjects uses daily doses of insulin administered orally. Neither injected nor oral insulin at the doses used were observed to delay or prevent diabetes, although further studies are needed to test whether oral insulin can delay diabetes in people in the intermediate risk group with high titers of insulin autoantibodies.

Multi-center double-masked, placebo-controlled randomized clinical trial designed to evaluate the long-term efficacy of finasteride, or doxazosin, or the combination of both, in delaying or preventing the clinical progression of symptomatic benign prostatic hyperplasia (BPH). MTOPS was the largest and longest study to test whether drug therapy can prevent or delay the noncancerous growth of the prostate. A unique feature of MTOPS that has not been done in prior studies of pharmacotherapy of BPH is the biopsy substudy. A total of 1,082 volunteers from the 2,931 participants randomized during the full-scale phase are currently participating in this substudy. Biopsies of the prostate will be obtained on these volunteers at predetermined times during the course of the trial to evaluate the status of the prostate at key event times. The purpose of the substudy was to provide additional information regarding the histopathobiology of BPH and to test existing biomarkers for their prognostic ability regarding response to drug therapy.

Observational clinical trial studying the long term effect of diet and exercise and the diabetes medication, metformin, on the delay of type 2 diabetes in participants of the Diabetes Prevention Program (DPP). The Diabetes Prevention Program (DPP) was a multi-center trial examining the ability of an intensive lifestyle or metformin to prevent or delay the development of diabetes in a high risk population due to the presence of impaired glucose tolerance (IGT). The DPP has ended early demonstrating that lifestyle reduced diabetes onset by 58% and metformin reduced diabetes onset by 31%. The DPPOS is designed to take advantage of the scientifically and clinically valuable DPP participants. This group of participants is nearly 50% minority and represents the largest IGT population ever studied. Clinically important research questions remain that focus on 1)durability of the prior DPP intervention, 2) determination of the clinical course of precisely known new onset diabetes, in particular regarding CVD, CVD risk factors and atherosclerosis and microvascular disease, 3)close examination of these topics in men vs women and in minority populations. More than 87% of the original surviving DPP cohort has joined DPPOS as of December, 2007 and, to date, after 5 years of DPPOS and 10 years of combined DPP/DPPOS, 93% of the DPPOS cohort continue to attend annual follow-up visits. Interim analyses performed after 5 years of DPPOS have demonstrated a durable effect of diabetes prevention associated with the lifestyle and metformin interventions with 34 and 19% reductions in diabetes incidence, respectively, compared with the placebo group. Interim analyses also reveal significant reductions from baseline in CVD risk factors in the lifestyle intervention group, but with decreased utilization of glucose-lowering and lipid-lowering medications. Analyses of the participants in the placebo group who have developed diabetes during DPP/DPPOS, compared with those who have remained non-diabetic, reveal an increased frequency of retinopathy and microalbuminuria. The current, updated protocol describes the DPPOS including the revisions incorporated to complete the second five-years of the study. DPPOS participants have blood samples stored at the time of each annual visit. Specimens are stored at the study CBL until after the primary study outcomes are reported. DNA samples were previously collected and are stored at the NIDDKsample repository for DPP participants.

Randomized controlled clinical trial to understand how increasing hemodialysis to six times a week from the standard of three times a week may result in improved heart health. Subjects were recruited from dialysis units associated with designated Clinical Centers in the U.S. and Canada and followed for 1 year. Subjects will be randomized to either conventional hemodialyis Daily HD delivered for at least 2.5 hours (typically 3 to 4 hours), 3 days per week, or to more frequent hemodialysis delivered for 1.5 - 2.75 hours, 6 days per week. The study has two co-primary outcomes: 1) a composite of mortality with the change over 12 months in left ventricular mass by magnetic resonance imaging, and 2) a composite of mortality with the change over 12 months in the SF-36 RAND physical health composite (PHC) quality of life scale. In addition, main secondary outcomes have been designated for each of seven outcome domains: 1) cardiovascular structure and function (change in LV mass), 2) health-related quality of life/physical function (change in the PHC), 3) depression/burden of illness (change in Beck Depression Inventory), 4) nutrition (change in serum albumin), 5) cognitive function (change in the Trail Making Test B), 6) mineral metabolism (change in average predialysis serum phosphorus), and 7) clinical events (rate of non-access hospitalization or death). Hypertension and anemia are also main outcome domains, but without designation of single first priority outcomes.

Study designed to test the hypothesis that African-Americans respond less well to combination pegylated interferon and ribavirin therapy than Caucasian-Americans who have chronic hepatitis C genotype 1 and who were not previously treated with either interferon or ribavirin. Reasons for differences in response, regardless of race, will be studied. All patients were treated with combination therapy of pegylated interferon and ribavirin for 48 weeks, and were followed for an additional 48 week safter cessation of therapy. 400 patients, half African-American and half Caucasian American, from 8 clinical centers with the goals of establishing rates of response to optimal current therapy in the two ethnic groups, identify factors predictive of response, establish patterns of viral kinetics in response to antiviral therapy, and test hypotheses concerning viral and host factors determining response to therapy. Four ancillary studies designed to elucidate biological and virological basis for non-response are also included in Virahep-C. Additionally, the study has central facilitates for pathology, the virological testing laboratory and a serum/tissue repository.

Randomized, multicenter, double blind, placebo controlled clinical trial of phytotherapy for benign prostate symptoms among men. The CAMUS trial will test Saw palmetto in about 369 men. Men who decide to be part of the CAMUS trial will be given one out of two possible treatments at random. One out of every two men would get an inactive placebo treatment. One out of every two men would get Saw palmetto pills. This kind of scientific study is the best way to find out if the plant extracts really work to prevent men with benign prostatic hyperplasia (BPH) from getting worse. During the study, men will not know which of the two treatments they are assigned to. They will be followed very closely by a study team every 12 weeks to see how they are doing. Men in the CAMUS trial will be studied over 72 weeks. Ten clinical centers will participate in the trial. They are located at: Columbia University, NY, NY; New York University, NY, NY; University of Texas Southwestern Medical Center, Dallas, Texas; University of Colorado, Denver, CO; Washington University, St. Louis, MO; Yale University, New Haven, CT; Queens University, Hamilton, Ontario, Canada; Northwestern University, Chicago, IL; University of Maryland, Baltimore, MD; University of California at San Francisco, San Francisco, CA.
