Filter by:The objective of the study is to assess the effect of standard versus aggressive inhibition of the renin-angiotensin system (RAS)in type 2 diabetic patients with microalbuminuria (MA) on; a)progression of microalbuminuria, b)estimated glomerular filtration rate (eGFR), c)endothelial dysfunction (measured by post-hyperemia arterial tonometry) and d)the slowing of the progression of atherosclerotic disease (measured by carotid intima media thickness [CIMT]).
This study was carried out in the context of daily medical practice to compare the effectiveness of telmisartan in the treatment of hypertension complicated or not with the presence of protein in the urine, which is called albuminuria. Hypertension is a chronic, treatable but not curable disease and is defined as a combination of a systolic blood pressure of 140 mmHg or more and a diastolic pressure of 90 mmHg or more. The kidneys are often the first organs damaged by hypertension; renal damage could easily be diagnosed using a urine dipstick and should be part of a routine examination in hypertensive patient. The aim of the study is to see if the decrease of blood pressure (both systolic and diastolic) after approximately 12 weeks of treatment with telmisartan in patients with albuminuria is the same or different to that in patients without albuminuria. Every patient participating should have two visits, approximately 12 weeks apart where his/her blood pressure was checked and a few questions about is concomitant disease and drugs were asked.
Patients with chronic kidney disease and albuminuria are at increased risk of developing cardiovascular disease which is often associated with hypertension, left ventricular hypertrophy, endothelial dysfunction and increased generation of reactive oxygen species (ROS). These patients also manifest a decrease in nitric oxide availability which is thought to play an important role in their progressive vascular disease. Tetrahydrobiopterin (BH4), an essential cofactor for endothelial nitric oxide synthase(eNOS), an important regulator of nitric oxide (NO) and that is a key mediator of endothelial dysfunction. Changes in nitric oxide availability are believed to contribute to endothelial dysfunction seen in chronic kidney disease and common cardiovascular disease states. 6R-tetrahydrobiopterin (6R-BH4 or sapropterin dihydrochloride) is an investigational oral drug that is being evaluated to determine whether it will restore NO availability, leading to beneficial effects on vascular function and ultimately positive clinical outcomes in patients with chronic kidney disease. The primary endpoint in this study is the level of albuminuria, an easily measured marker that has served as a predictor of kidney disease progression. If 6R-BH4 reduces albuminuria in patients with kidney disease, it may have implications to slow the disease progression as well as decreased risk of cardiovascular disease.
This research project will look at the relationship between baseline variables, and the new onset of microalbuminuria and the response to treatment with an angiotensin receptor blocker, losartan, in a cohort of 246 early hypertensives and normotensives who are being brought back for a 4-5 year follow up visit as part of a continuing project. We hypothesize that the new onset of microalbuminuria is associated with higher blood pressure levels at baseline and 1 year as well as being associated with elevated left ventricular mass index. The rate of new onset microalbuminuria in non-diabetics is not established and this prospective study will provide data.
This is a phase II a, double-blind, randomized, parallel-design, four-week study to investigate the efficacy, safety and tolerability of two different doses of SPP635 in type II diabetic patients with mild to moderate hypertension and albuminuria. The total study duration for patients completing the entire study will be approximately 7 weeks including a 2 weeks Screening Phase, 1 week Wash-out Phase, 4 week Treatment Phase and 1 week Follow-up Phase. All treatments other than certain antihypertensive drugs (which are to be washed-out) with an effect on BP and all antidiabetic treatments must be kept at stable dose during the whole study. A maximum of 50 patients in total is planned to be enrolled.
This study is designed to assess the efficacy of the different dosage forms of Valsartan[80, 160, and 320 mg] in reducing microalbuminuria/proteinuria in hypertensive patients with type 2 diabetes.
This study will examine the following: 1) how common albuminuria and proteinuria are among HIV-positive patients, 2) what causes albuminuria or proteinuria in these patients and 3) whether the condition becomes more severe over time. HIV-infected people are more likely than others to develop kidney disease. The earliest indicator of the possible presence of kidney disease is albuminuria (increased amounts of the protein albumin in the urine). A later indicator is the appearance of other proteins, a condition called proteinuria. HIV-infected patients 8 years of age and older who do not have diabetes, chronic kidney disease or cancer may be eligible for this study. Participants provide a urine sample during three visits as follows: the first upon enrollment in the study, a second 3 months later, and a third about 6 months after that. Blood samples are drawn at the first and last visits. At the first visit a medical history is taken and blood pressure, height, weight, waist circumference, hip circumference and upper arm skin thickness are measured. Participants who are found to have albuminuria or proteinuria are asked to undergo a kidney biopsy for research purposes. The procedure is optional. Participants who develop heavy proteinuria may be recommended to undergo a kidney biopsy in order to determine the nature of the kidney disease and begin treatment. The biopsy requires a 2-day hospital stay. For the procedure, an anesthetic is given to numb the skin and a needle is inserted and guided into the kidney to withdraw a small tissue sample. The needle is passed twice, and possibly three times. Following the procedure, the subject remains in bed rest for at least 10 hours to minimize the risk of excessive bleeding.
Diabetic nephropathy (DN) is a chronic diabetic complication and affects up to 40% of patients. The first line treatment for DN is angiotensin blockers drugs that are used to reduce the protein concentration in urine.Previous data showed that this protein, namely albuminuria, could also be reduced in a short term-period by the replacement of red meat in the diet with chicken. The aim of this study is to compare the effects of this chicken diet with enalapril on albuminuria in a long-term period( 12 months)in type 2 diabetic patients.
Primary objective: - To assess the effect on microalbuminuria levels of treatment with rimonabant 20 mg versus a placebo during a 12 month period. Secondary objectives: - Percentage of patients in both arms of the study whose levels of microalbuminuria decrease, stabilise, increase towards macroalbuminuria or are unchanged after 12 months of treatment with rimonabant or placebo. - To assess the effect of treatment with rimonabant 20 mg versus placebo over a 12 month period on: - Weight and waist circumference. - Glycaemia profile: fasting glycaemia, fasting insulinaemia and HbA1c. - Lipid and lipoprotein profile: triglycerides, total cholesterol, HDL-C, LDL-C, apolipoproteins A1 and B. - Inflammatory markers - Adipocytokines. - Blood pressure. - Glomerular filtration rate. - To assess the quality of life by means of questionnaire filled in. - Safety parameters
The study objective was to evaluate the safety of paricalcitol capsules and the efficacy of paricalcitol capsules for albuminuria reduction in patients with Chronic Kidney Disease (CKD) who have Type 2 diabetic nephropathy and are receiving optimal angiotensin converting enzyme (ACE) inhibitor and/or angiotensin II receptor blocker (ARB) therapy.
