Efficacy of low dose atorvastatin in diabetic dyslipidaemia.J Indian Med Assoc. 2009 Nov; 107(11):807-9.JI
Coronary heart disease (CHD), the commonest cause of morbidity and mortality in patients with type 2 diabetes, requires multipronged approach for management, including especially treating dyslipidaemia with statins. We conducted this study to demonstrate that low dose (10 mg) atorvastatin is effective in reducing LDL cholesterol (LDL-C) to the target levels in patients from Indian subcontinent. Eighty-one subjects with type 2 diabetes mellitus and dyslipidaemia (LDL-C >100 mg/dl in those without coronary artery disease, n=77; LDL-C >70 mg/dl in those with coronary artery disease, n=4) were included. All patients were initiated on 10 mg atorvastatin daily. Serum lipid profile was repeated after 3 months. The mean body mass index among men and women were 25.0 +/- 4 and 26.7 +/- 3.6 kg/m2 respectively. Pretreatment mean HbA(1c) was 7.9 +/- 1.8 % and total cholesterol, triglycerides and HDL cholestrol (HDL-C) and LDL-C was 214 +/- 27 mg/dl, 164 +/- 63 mg/dl, 46 +/- 6 mg/dl and 135 +/- 24 mg/dl respectively. After three months of treatment the mean decrease was 62 +/- 31 mg/dl in total cholesterol (p < 0.001), 31 +/- 57 mg/dl in triglycerides (p < 0.001), 51 +/- 27 mg/dl in LDL-C (p < 0.001) and 4 +/- 8 mg/dl in HDL-C (p < 0.001). The LDL-C level was reduced by 37.6% in these patients, from 135 +/- 24 mg/dl to 84 = 27 mg/dl (p < 0.001) with 10 mg of atorvastatin daily. It was possible to achieve target LDL-C of less than 100 mg/dl in 75.5% (n=58) in subjects without CHD (n=77) and less than 70 mg/dl in 75% (n=3) of those patients with CHD (n=4). The present study showed that in patients with type 2 diabetes mellitus, 10 mg of atorvastatin daily was safe, well tolerated, and effective in reducing LDL-C to target levels.
