The effects of chlorpropamide and insulin on serum lipids, lipoproteins and fractional triglyceride removal.
The effects of chlorpropamide on serum lipids, lipoproteins and fractional triglyceride removal have been studied over 12 months on 10 maturity onset diabetics not controlled on diet alone. Similar studies were carried out in 6 maturity onset diabetics who had failed to respond to sulphonylureas and 6 new insulin requiring diabetics. In the chlorpropamide treated patients there was an initial fall in serum and VLDL triglyceride but this effect was lost at 12 months. There was no change in fractional triglyceride removal. At 12 months there was a fall in LDL and a rise in HDL choelsterol. An initial improvement in glucose tolerance and insulin secretion was maintained at 12 months. In the insulin treated group the initial fall in serum and VLDL triglyceride was maintained at 12 months and was accompanied by an increase in fractional triglyceride removal. There was also a fall in LDL and a rise in HDL cholesterol at 12 months. The failure of chlorpropamide to maintain the reduction in serum and VLDL triglyceride could be of importance in the genesis of coronary heart disease in maturity onset diabetics. The fall in LDL and rise in HDL cholesterol found both with chlorpropamide and insulin might be beneficial.[1]References
