Obesity-induced Hyperfiltration clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Effect of Acetazolamide and Furosemide on Obesity-induced Glomerular Hyperfiltration

Start date: July 2010
Phase: N/A
Study type: Interventional

Background: Obesity is associated with a high prevalence of chronic kidney disease.The glomerular hyperfiltration associated with obesity may play a role in the pathogenesis of obesity associated chronic kidney disease. Attenuation of hyperfiltration by pharmacological means may slow down the development and progression of chronic renal failure. The investigators have previously shown that acetazolamide, a proximally acting diuretic that activates tubuloglomerular feedback(TGF) by increasing solute delivery to the Macula DENSA, abates glomerular hyperfiltration. The present study was designed to test the hypothesis that this decrease in hyperfiltration is specific to acetazolamide and not due to a non specific diuretic effect. The aim of the present study is to compare the effects of furosemide and acetazolamide on glomerular hemodynamics in subjects with severe obesity. Methods: A randomized double-blind crossover controlled design will be used. Fifteen obese subjects and ten subjects with normal body weight will participate in the study. Obese subjects will undergo measurement of glomerular filtration rate (GFR)(inulin clearance), renal plasma flow (RPF) (p-aminohippuric acid clearance), filtration fraction, fractional excretion of lithium (FE LI) and blood pressure, before and after intravenous administration of furosemide 2 mg. and acetazolamide 5 mg/kg BW. Ten subjects with normal body weight will undergo measurement of renal function without administration of diuretics.
