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)
