Lipids, lipoproteins and apolipoprotein (a) isoforms in type 2 diabetic patients
1Hospital General Yagüe, Burgos, Spain. calmarza@bio.hgy.es
Background:
Patients with type 2 diabetes mellitus have a greater than normal risk of developing atherosclerotic vascular diseases. Higher than normal plasma concentrations of lipoprotein (a) [Lp(a)] have been associated with premature atherosclerosis in several studies.
Objective:
To determine the concentrations of lipids, lipoproteins, and Lp(a) in 107 type 2 diabetic patients, and the distribution of apolipoprotein (a) [apo(a)] phenotypes for this group, and to compare the results found with results for healthy subjects.
Results:
Plasma concentrations of cholesterol, triglycerides, and apolipoprotein B in the diabetics were significantly higher than those in control subjects. Diabetic patients had slightly lower Lp(a) concentrations than did nondiabetic subjects, but these differences were not statistically significant. Distributions of Lp(a) concentrations both in type 2 diabetic patients and in control subjects were markedly skewed, the highest prevalences being of low values.
Conclusion:
Distributions of apo(a) phenotypes for patients with type 2 diabetes mellitus and controls were remarkably alike. Smaller isoforms were similarly prevalent for the two populations, as were the null, single-band and double-band apo(a) phenotypes.
