Gender dependent effects of fasting blood glucose levels and disease duration on biochemical markers in type 2 diabetics: A pilot study.

AIM: The impact of fasting blood glucose levels (FBG) and disease duration on type 2 diabetes in Indian population is still unclear. The present study examines gender-dependent effects of FBG and disease duration on lipid profile, adipocytokines and related biochemical parameters in diabetic individuals.

METHODS

Type 2 diabetic individuals (n=100) were classified depending on FBG: patients with normal FBG (Glucose<126mg/dl) and patients with high FBG (Glucose≥126mg/dl); and disease duration: ≥0-≤3yr, >3-≤7yr, >7yr.

RESULTS

Males with high FBG had significantly higher serum glucose, triglycerides, very low density lipoprotein (VLDL), serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT) and waist hip ratio (WHR) than males with normal FBG. Females with high FBG had significant increase in serum glucose, adiponectin and creatinine while decrease in leptin levels than females with normal FBG. Males with high FBG had higher WHR, superoxide dismutase, SGOT, SGPT and lower adiponectin, leptin than females with high FBG. Significant positive association was observed between glucose and cholesterol, triglyceride, VLDL and urea in males with high FBG. With chronic diabetes for >7yr, males had increased systolic blood pressure, glucose, LDL, urea and low catalase activity as compared to other disease duration groups. However, females had higher adiponectin, creatinine and lower body mass index and cholesterol.

CONCLUSIONS

High FBG in males adversely affects lipid profile, adipocytokines and liver function. Some of these effects exacerbate as disease progresses. Higher adiponectin may have desirable effects on metabolic markers in females.
