Association between Glycemic Control and Serum Lipid Profile in type 2 Diabetic Patients: Experience in a Medical College Hospital

Abstract

Impaired lipid metabolism in diabetic patients can lead to cardiovascular complications. Poor glycaemic control is associated with a significant increase in the risk of both patient’s morbidity and mortality. An early intervention to regulate circulating lipids has been found to lower the risk of cardiovascular problems and death. Glycated hemoglobin (HbA1c) is a reliable indicator of rising blood sugar levels. This hospital based observational study was conducted in the Department of Medicine, Sher-E-Bangla Medical College Hospital, Barisal from October 2014 to March 2015 over a period of 6 month to determine the correlation of glycemic control and lipid profile in patients with type 2 diabetes. A total of 110 type 2 diabe- tes mellitus(DM) patients of both sexes admitted to the Deapartment of Medicine of Sher-E- Bangla Medical College Hospital, Barisal, were recruited for this study. Following standard procedures and protocols, fasting blood sugar (FBS), blood sugar two hours after breakfast, Glycosylated Hemoglobin (HbA1c) and fasting lipid profile were measured. The age of respondents ranged from 34 to 70 years with the mean age of 54.35}8.02 years. Among the patients male were 70 (63.6%) and female were 40 (36.4%). Mean age at diagnosis of DM and duration of DM was 47.07}6.03 years and 7.27}3.41 years, respectively. Mean body mass index (BMI), FBS and HbA1c were 25.02}5.22 kg/m2, 8.06}2.01 mmol/L and 8.34}1.9 % respectively. Significant positive correlation of HbA1c and FBS with BMI, total cholester- ol(TC), triglyceride(TG), low density lipoprotein(LDL-C) and negative correlation with high density lipoprotein (HDL-C) was found. Significantly higher TC, TG and LDL-C and lower HDL-C were found in poor glycemic control (HbA1c ≥ 7) group than good glycemic control (HbA1c < 7 ) group. The results of this study showed that , higher levels of glycemic parame- ters are significantly associated with dyslipidemia. These findings also indicate that HbA1c can be utilized for screening of high risk diabetic patients for early diagnosis of dyslipidemia and timely intervention with lipid lowering drugs.

Evaluation of Serum Triglyceride and TG/HDL-Cholesterol Ratio in Good and Poor Control Type-2 Diabetes Mellitus

“…(p=0.001) The mean value of the ratio TG/HDL-cholesterol in a group of patients with good glycemic control was 4.19±1.11 and in the group of patients with poor glycemic control was 25.8±2.4. Similar findings were observed in other studies 19,20 .…”
