enisoprost and Diabetes-Mellitus--Type-2

Short-term studies have suggested that analogs of prostaglandin E may have favorable effects on the carbohydrate and lipid metabolism in patients with type II diabetes mellitus. The present study was undertaken to investigate the long-term effects of a prostaglandin E1 analog on the regulation of glycemic control and plasma lipids. Twenty patients with type II diabetes received enisoprost, 300 mcg/day, for three months. Fasting serum glucose, glycosylated hemoglobin, insulin and C-peptide levels as well as triglyceride, total cholesterol, high density lipoprotein cholesterol and its subfractions, apolipoproteins B and AI and post-heparin lipoprotein lipase and hepatic triglyceride lipase activities were determined. During the first month, enisoprost treatment caused significant decreases in plasma glucose (baseline = 8.72 +/- 0.39 mmol/L, 4 week = 7.78 +/- 0.5 mmol/L, change = -0.94 +/- 0.28 mmol/L, p less than 0.01) and total cholesterol (baseline = 5.30 +/- 0.23 mmol/L, 4 week = 5.01 +/- 0.26 mmol/L, change = -0.28 +/- 0.06 mmol/L, p less than 0.05). The decrease in cholesterol level was due to a reduction in high density lipoprotein, specifically in high density lipoprotein2 fraction (baseline = 1.29 +/- 0.1 mmol/L, 4 week = 1.12 +/- 0.08 mmol/L, change = -0.018 +/- 0.04 mmol/L, p less than 0.05 for the former and baseline = 0.40 +/- 0.06 mmol/L, 4 week = 0.27 +/- 0.03 mmol/L, change = -0.12 +/- 0.03 mmol/L, p less than 0.05 for the latter): All of these values returned to the pretreatment levels despite continuation of enisoprost.(ABSTRACT TRUNCATED AT 250 WORDS)
