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.

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.

Randomized controlled clinical trial where subjects will be randomized to conventional hemodialysis delivered three days per week home arm or to the six times per week nocturnal home hemodialysis arm which will follow any dialysis prescription provided their prescribed standardized Kt/V is at least 4.0 and treatment time is at least 6.0 hours, six times per week. Subjects were recruited from dialysis units associated with designated Clinical Centers in the U.S. and Canada and followed for 12 months. Primary Outcome Measures: * composite of 12 month mortality and the change over 12 months in left ventricular mass by cine-MRI, * a composite of 12 month mortality and the change over 12 months in the SF-36 RAND physical health composite Secondary Outcome Measures: * cardiovascular structure/funct (change in LV mass over 12 mos), health-related QoL/phys funct (change over 12 mos in PHC), * depression / dis burden (change over 12 mos in Beck Depression Inv.), nutrition (change over 12 mos in serum albumin, cognitive funct (change over 12 mos in TrailMaking Test B), mineral metabolism (change over 12 mos in aveg pre-dialysis serum phosphorus), * clin events (rate of non-access hospital or death * hypertension, anemia

Multicenter observational study designed to identify genetic determinants of diabetic nephropathy. It is conducted in eleven U.S. clinical centers and a coordinating center, and with four ethnic groups (European Americans, African Americans, Mexican Americans, and American Indians). Two strategies are used to localize susceptibility genes: a family-based linkage study and a case-control study using mapping by admixture linkage disequilibrium (MALD). In the family-based study, probands with diabetic nephropathy are recruited with their parents and selected siblings. Linkage analyses will be conducted to identify chromosomal regions containing genes that influence the development of diabetic nephropathy or related quantitative traits such as serum creatinine concentration, urinary albumin excretion, and plasma glucose concentrations. Regions showing evidence of linkage will be examined further with both genetic linkage and association studies to identify genes that influence diabetic nephropathy or related traits. Two types of MALD studies are being done. One is a case-control study of unrelated individuals of Mexican American heritage in which both cases and controls have diabetes, but only the case has nephropathy. The other is a case-control study of African American patients with nephropathy (cases) and their spouses (controls) unaffected by diabetes and nephropathy; offspring are genotyped when available to provide haplotype data. The specific goals of this program: * Delineate genomic regions associated with the development and progression of renal disease(s) * Evaluate whether there is a genetic link between diabetic nephropathy and diabetic retinopathy * Improve outcomes * Provide protection for people at risk and slow the progression of renal disease * Help establish a resource for genetic studies of kidney disease and diabetic complications by creating a repository of genetic samples and a database * Encourage studies of the genetics of progressive renal disease

Multicenter, randomized, double-blind, placebo-controlled trial is designed to determine whether daily antimicrobial prophylaxis is superior to placebo in preventing recurrence of urinary tract infection (UTI) in children with vesicoureteral reflux (VUR). The basic eligibility criteria are: (1) age at randomization of at least 2 months, but less than 6 years, (2) a diagnosed first febrile or symptomatic UTI within 42 days prior to randomization that was appropriately treated, and (3) presence of Grade I-IV VUR based on voiding cystourethrogram (VCUG). Patients will be randomly assigned to treatment for 2 years with daily antimicrobial prophylaxis (trimethoprim-sulfamethoxazole) or placebo. The study is designed to recruit 600 children (approximately 300 in each treatment group) over an 18-24 month period. The primary endpoint is recurrence of UTI. In addition, patients will be evaluated for secondary endpoints related to renal scarring and antimicrobial resistance. Scarring will be determined based on renal scintigraphy by 99mTc dimercaptosuccinic (DMSA) scan. Quality of life, compliance, safety parameters, utilization of health resources, and change in VUR will be assessed periodically throughout the study.
