title: Renal excretion of prostaglandin E2 and plasma renin activity in type I diabetes mellitus: relationship to normoglycemia achieved with artificial pancreas.
abstract: To determine the effect of normoglycemia on renal prostaglandin synthesis and renin-angiotensin system activity, prostaglandin E2 (PGE2) urinary excretion, plasma renin activity (PRA), and glomerular filtration rate (GFR) were studied in seven patients with insulin-dependent diabetes mellitus (IDDM) without complications, both in basal conditions and after a 20-h treatment with an artificial pancreas. Normoglycemia induced a significant reduction in PGE2 excretion (88 +/- 23 vs. 55 +/- 25 ng/12 h, P less than .05) and GFR (138 +/- 34 vs. 105 +/- 20 ml X min-1 X 1.73 m-2, P less than .05) and a nonsignificant increment of PRA (0.52 +/- 0.48 vs. 0.83 +/- 0.92 ng X ml-1 X h-1). The results enhance the hypothesis that renal prostaglandins play a role in the renal functional alterations observed in IDDM during hyperglycemia.
