Abstract
AIM: Lipoprotein lipase (LPL) is a key enzyme of lipid metabolism, and its genetic polymorphism may be a candidate for modulating lipid parameters in type 2 diabetic subjects (D2). METHODS: In a group of 404 type 2 diabetic patients, aged 59.5+/-10.8y, BMI=28.9+/-5.3 kg/m2, HbA1c=8.2+/-1.9%, we studied the H and P polymorphisms at the LPL locus detectable with the restriction enzymes HindIII and PvuII. Patients were separated into 229 males (17H1H1, 84H1H2, 128H2H2 and 51P1P1, 110P1P2, 68P2P2) and 175 females (16H1H1, 69H1H2, 90H2H2 and 51P1P1, 85P1P2, 39P2P2), and compared on the basis of their lipid parameters and their macrovascular complications. RESULTS: Triglyceride (TG) and HDL-cholesterol(c) concentrations differed between patients with and without coronary heart disease (CHD) (3.44+/-2.09 and 1.96+/-1.40 mmol/l for TGs and 1.05+/-0.24 and 1.34+/-0.40 mmol/l for HDL-c, P<0.001). HDL-c concentrations were lower in male H2H2 and P2P2 subjects (P<0.001), and TG levels were higher in male H2H2 and P2P2 subjects (P<0.0001 for Hind III and P<0.05 for PvuII). Allele frequency of the HindIII and PvuII restriction site was similar to those reported in other Caucasian populations and the presence of the H2/P2 variants was significantly higher in CHD patients. The prevalence of CHD in this population was 18% but was 29% in H2H2 and 38% in P2P2 subjects (P<0.02). CONCLUSION: Thus, HindIII and PvuII polymorphisms seem to exert a modulating role on lipid profile particularly in male D2, contributing to increase the risk of macrovascular events.
