Filter by:This project is a clinical study of women with high blood pressure who become pregnant. Preeclampsia is a syndrome developing at the end of a pregnancy characterized by an abrupt rise in blood pressure (BP), blood clotting and kidney dysfunction, and may result in premature delivery, infant death, and maternal bleeding, kidney failure and stroke. The goal is to determine whether lowering blood pressure to a normal pressure of 120/80 is associated with a lower incidence of preeclampsia. Women who are completely healthy have a 5% chance of developing preeclampsia, however women with preexisting high blood pressure have a 25% chance of this complication. Several studies, including our own suggest that higher blood pressure early in pregnancy (<20 weeks) is associated with an even higher risk of preeclampsia. Currently we, the researchers at Weill Medical College of Cornell University, do not know how to treat women with high blood pressure and/or kidney disease during pregnancy. Keeping the BP in the normal range may be beneficial to the mother. On the other hand, we are not sure if the blood pressure lowering or the medications may or may not have adverse effects for the baby. Different trials to answer this question have been performed with no clear conclusions. Because of these uncertainties, we propose to compare two different strategies for treating women with high BP who become pregnant. We will treat half the women with BP medications to normalize BP (120-130/80 mm Hg) (experimental group) and the other half with the goal of keeping the BP slightly higher (140-150/90-100 mm Hg)(standard therapy group). We will determine which approach results in healthier pregnancies, and lower incidence of preeclampsia. Reducing the incidence of preeclampsia would be of significant benefit to both mothers and babies.
Among adults with Human Immunodeficiency Virus (HIV) and Acquired Immunodeficiency Syndrome (AIDS), Chronic Kidney Disease (CKD) has previously been reported to occur in approximately 10% of children with HIV-infection. The frequency of CKD, its causes, and its natural history in children and adolescents with HIV-infection have not been systematically studied, particularly in the era of new anti-retroviral medications. The primary aim of this study is to determine the how common pediatric HIV-infected individuals have evidence of persistent proteinuria and CKD.
The purpose of the study is to evaluate the effectiveness and safety of olmesartan versus placebo on the progression of diabetic renal disease.
The purpose of this study is to determine which combination of the tablets ramipril, irbesartan or spironolactone is best to lower protein leakage from the kidney.
Study of the efficacy and safety of aliskiren when added to losartan and optimal antihypertensive therapy in patients with hypertension, type 2 diabetes, and kidney disorders to monitor improvement in any of these conditions.
Chronic allograft nephropathy continues to be a major cause of kidney transplant loss and return to dialysis. Treatment options are limited and the course of the disease tends to be progressive. This trial is designed to prevent a major mediator of this process, namely the expansion of the cortical interstitial compartment of the kidney where most of the scarring occurs. The drug being studied, Losartan, has proven efficacious in a number of kidney diseases.
Much more about kidney disorders can be learned by determining kidney function. This research proposes to study the kidneys function by several parameters known as glomerular filtration rate (GFR), Renal Plasma Flow (RPF), and Glomerular Capillary Wall Permselectivity. The study will select patients suffering from different types of kidney diseases. These patients will be selected based on the presence of significant amounts of protein in their urine (proteinuria). Standard blood and urine tests are often unable to provide completely accurate information about the kidney. In order for researchers to have a more accurate idea of kidney function, they will use alternative tests. Test materials (para aminohippurate and inulin) will be injected into patients veins that provides information based on their filtration through the kidneys....
This study will examine the effectiveness of the drug pirfenidone in treating focal segmental glomerulosclerosis (FSGS). Patients with this disease have kidney fibrosis (scarring) and proteinuria (excessive excretion of protein in the urine). About half of patients with FSGS eventually require kidney dialysis or transplant. Steroids, which are currently used to treat the disease, are effective in only a minority of patients. Other drugs, such as cyclosporin and cyclophosphamide, improve proteinuria in a very small percentage of patients and have serious side effects. Patients with FSGS who wish to participate in this study will undergo pre-study evaluation with blood and urine tests. Patients must be on a stable dose of an ACE inhibitor (a drug that lowers blood pressure and reduces proteinuria) for at list 6 months before starting pirfenidone therapy. (Patients who are not already taking an ACE inhibitor will be started on the drug; those who cannot tolerate ACE inhibitors will be given a different drug.) Patients with elevated cholesterol will take a cholesterol-lowering drug. A diet containing approximately 1 gram of protein per kilogram of body weight per day will be recommended. Patients will take pirfenidone by mouth 3 times a day for 12 months. Blood and urine will be tested once a month, either at NIH or by the patient's local kidney specialist. They will collect two 24-hour urine samples at the beginning of the treatment period, at 2-month intervals throughout the study, and at a 6-month follow-up. Patients will also be asked to give three to five tubes of blood and urine samples for analysis during the study. In animal studies, pirfenidone improved kidney function and proteinuria and reduced kidney scarring in rats with a disease similar to FSGS. In human studies, pirfenidone improved breathing and survival in patients with lung fibrosis.
