Renal effects of oral prostaglandin supplementation after ibuprofen in diabetic subjects: a double-blind, placebo-controlled, multicenter trial.

Prostaglandins of the E series (PGE) are known to contribute to the maintenance of renal hemodynamics in subjects with chronic renal insufficiency. Agents that block PGE synthesis, nonsteroidal anti-inflammatory agents (NSAID), are widely used by people with renal insufficiency. This study was undertaken in subjects with renal insufficiency secondary to diabetes to evaluate the acute effects of a PGE1 analog, misoprostol, on NSAID-induced changes in RBF, as calculated by para-aminohippurate clearance, and GFR, as calculated by inulin clearance.

Androgens potentiate the effects of erythropoietin in the treatment of anemia of end-stage renal disease.

Since androgens may increase the sensitivity of the erythroid progenitors to erythropoietin, the present studies were designed to investigate the effect of administration of androgens on the actions of exogenous erythropoietin (EPO) in hemodialysis patients. Studies were performed in a group of 15 adult male hemodialysis patients. Seven patients were treated with EPO alone at a dose of 2,000 U intravenously (IV) three times a week.
