Oxidative Stress and Glycaemic Control in Type 2 Diabetic Patients in Enugu; South-East Nigeria

Background: There is growing evidence that excess generation of highly reactive free radicals; largely due to hyperglycaemia causes oxidative stress; which further exacerbates the development and progression of type 2 diabetes and its complications. Objectives: In this study; the level of oxidative stress was compared with glycaemic control in type 2 diabetic patients. Method: Fifty confirmed type 2 diabetic patients; aged between 25 and 70 years were used for the study. 20 patients with good glycaemic control served as positive control while 20 apparently healthy non-diabetic age-matched individuals served as negative control. The FBS; MDA and HbA1c were determined in fasting blood samples using standard methods. Results: Patients with poor glycaemic control had significantly raised MDA and HbA1c (P =0.0001) when compared with non diabetics However; those with good glycaemic control only had a significant increase in the MDA when compared to non diabetic. (P =0.0001).).The MDA level when compared to fasting blood sugar (FBS) and glycated haemoglobin (HbA1c) showed a positive correlation.( r= 0.77; P = 0.0001 and r=0.69; P = 0.0001 respectively) Conclusion: This study showed that both glycaemic control and lipid peroxidation are factors to be monitored or evaluated in the management of type2 diabetics to avoid the development of diabetic complications

Atherogenic index of plasma as useful predictor of cardiovascular risk among postmenopausal women in Enugu, Nigeria.

BACKGROUND: Menopausal health in our environment has received little attention. As an independent risk factor for dyslipidaemia, the degree and pattern of derangement, though difficult to assess may adversely affect the cardiovascular health of our women. OBJECTIVES: To estimate the serum lipid profile and the atherogenic index of plasma in normal post menopausal women. METHODS: This is a cross sectional study involving 80 apparently healthy women voluntarily recruited from staff of the University of Nigeria and the Teaching Hospital (UNTH) located in Enugu. They include 50 postmenopausal subjects aged between 50 and 70 years and 30 premenopausal controls aged between 25 and 49 years. Total cholesterol (TC), and the various subfractions; high density lipoprotein cholesterol (HDL-C), very low density lipoprotein cholesterol (VLDL-C), low density lipoprotein cholesterol (LDL-C) and triglycerides (TG) were determined. Atherogenic index of plasma (AIP); log (TG/HDL-C) was calculated. RESULTS: There were statistically significant increases (P< 0.0001) in TC, TG, LDL-C, VLDL-C and AIP but a statistically significant decrease (P<0.0001) in HDL-C in postmenopausal women when compared with the premenopausal subjects. Except HDL-C that showed insignificant reduction, there were statistically significant derangement of other lipid subfractions as the duration of menopause increased. CONCLUSION: Menopause, no doubt alters lipid profile. A triglyceride based index (AIP) can significantly add value when assessing the risk of developing atherosclerosis in Nigeria.
