Class G Autoantibodies to Oxidatively Modified Low Density Lipoprotein in Type 2 Diabetes Mellitus Patients Who Have Had Non-Q-Myocardial Infarction

Abstract

The article presents the results of a study of class G autoantibodies to oxidatively modified low-density lipoprotein (ox-LDL) in patients with type 2 diabetes mellitus which have had non-Qmyocardial infarction and their connection with disturbances of carbohydrate and lipid metabolism, the levels of cytokines. It was identified the decrease level of IgG to ox-LDL in the serum of these patients compared with the control group and patients without diabetes. The study found that with increasing degree of insulin resistance, the concentration of class G autoantibodies to ox-LDL in diabetic postinfarction patients was reduced. It was also revealed their direct connection with the level of anti-inflammatory IL-10. The data obtained may be evidence of the negative impact of carbohydrate metabolism disorders on the level of IgG autoantibodies to ox-LDL and the data may refer to their protective role in type 2 diabetes mellitus with concomitant atherosclerosis.
