Title: The effect of type 2 diabetes on HDL-cholesterol oxidative stress profile in patients with ischemic heart disease


Recent observational studies have confirmed that the atheroprotective activity of properly functioning HDL-C is frequently impaired in clinical situations associated with oxidative stress like diabetes type 2 (T2D). The objective of this study was to analyze the effect of T2D on apolipoprotein A-I (ApoA-I) and apolipoprotein A-II (ApoA-II), hsCRP, oxidative stress markers (MDA, 8-iso-PGF2α, and Ox-LDL), and enzymes that modify HDL-C function (MPO and PON-1) in patients with ischemic heart disease (IHD). An observational cross-sectional study was conducted. Patients were recruited to two study groups. In total, the study included 70 patients, 35 of whom had IHD with T2D, and 35 had IHD without T2D. Data on demographic characteristics, physical activity, diet, smoking status, concomitant diseases, and current medications were collected from each patient. The quantities of ApoA-I, ApoA-II, Ox-LDL, MDA, 8-iso-PGF2α, MPO, PON-1, hsCRP were measured. The study revealed no significant differences in the serum levels of ApoA-I and ApoA-II, hsCRP, and oxidative stress markers between the groups. However, it revealed a significant difference in the serum levels of the enzymes between the groups. Our results showed increased MPO levels in diabetes patients. The analysis also revealed that T2D is independently associated with an increase in MPO levels. Simultaneously, a decrease in PON-1 l ; evels was observed in patients with T2D. The study also revealed that T2D is independently associated with a decrease in PON-1 levels. Finally, we revealed a positive correlation between the levels of TG and those of Ox-LDL and 8-iso-PGF2α.
