title: Serum lipoproteins in diabetes: relation of alpha-lipoprotein level to therapy.
abstract: Three hundred and sixty diabetic patients (125 on insulin, 109 on sulfonylureas and 126 on diet alone) were selected to investigate the effect of the type of treatment and of the degree of metabolic control on serum lipoproteins. Prebeta-lipoprotein concentration was higher than normal in all treatment groups. Beta-lipoproteins were significantly higher in diabetic women than in controls. No difference in beta- and prebeta-lipoprotein concentration existed between the 3 treatment groups. Alpha-lipoproteins were significantly higher in insulin-treated than in diet-treated patients irrespective of the degree of metabolic control. The daily dose of insulin and, in patients on diet or sulfonylureas, serum IRI were positively correlated to alpha-lipoprotein concentration while this lipoprotein fraction was not significantly correlated to fasting blood sugar. Alpha-lipoprotein concentration, then, appears to be markedly influenced by exogenous and endogenous insulin, independently of the degree of metabolic control.
