Abstract
AIM AND OBJECTIVES: To study the postprandial lipid abnormalities in patients with type 2 diabetes mellitus.
MATERIAL AND METHODS: Postprandial lipids were studied in 20 male type 2 diabetic subjects (age 49.75 +/- 4.82 years) and 20 age and sex matched healthy controls (age 49.55 +/- 4.82 years) after an oral fat challenge which consisted of a meal providing 729 keal/m2 body surface area with 68 gm fat.
RESULTS: Average duration of diabetes among diabetic was 2.32 +/- 3.03 years. The body mass index (cases 25.84 +/- 4.52; controls 25.74 +/- 5.0; p > 0.05) and waist-hip ratio (cases 1.06 +/- 0.13; controls 1.14 +/- 0.2; p > 0.05) were similar in both groups. While fasting serum lipids were not significantly different between the two groups, a number of serum lipid abnormalities were noted in type 2 diabetic subjects in the postprandial state. These included a higher triglyceride-area under curve (AUC) (cases 1298.08 +/- 485.2 vs. controls 922.15 +/- 390.47 mg/dl/8h; p=0.01), a higher triglyceride-area under incremental curve (AUIC) (cases 549.68 +/- 382.24; control 294.75 +/- 172.6 mg/dl/8h; p=0.01), a higher peak triglyceride level (cases 425.2 +/- 204.47 mg%, controls 283.9 +/- 11.6.94 mg%, p=0.01), a lower HDL-AUC (cases 130.35 +/- 33.55 vs. controls 168.48 +/- 56.01 mg/dl/8h, p=0.013) and a lower HDL nadir (Cases 28.05 +/- 10.94 mg%, controls 37.13 +/- 13.52 mg%, p < 0.02). Triglyceride AUC correlated significantly with fasting serum triglyceride (r=0.62) and BMI (r=0.7), but not with waist hip ratio or fasting serum insulin levels. Postprandial lipaemia did not correlate with age, duration of diabetes, fasting blood glucose or glycosylated hemoglobin.
CONCLUSION: In conclusion, make type 2 diabetics demonstrate significant postprandial lipid abnormalities, particularly of triglycerides, which appear to be independent of glycaemic control.
