title: Prevalence of non-alcoholic fatty liver disease and its correlation with coronary risk factors in patients with type 2 diabetes.
abstract: OBJECTIVE
  To estimate the prevalence of non-alcoholic fatty liver disease (NAFLD) by ultrasonography, and to correlate NAFLD with coronary artery disease (CAD) and coronary risk factors in a group of Indian type 2 diabetics.
  
  
  METHODS
  Consecutive patients of type 2 diabetes were recruited. History and physical examination were recorded. Laboratory investigations included fasting and 2-hour post-prandial blood glucose, blood urea, serum creatinine, liver function tests, lipid profile, glycated haemoglobin, microalbuminuria, and ultrasonographic measurement of carotid intimal-medial thickness (CIMT). NAFLD was diagnosed on the basis of ultrasound assessment of the liver.
  
  
  RESULTS
  The study group (n=124) was divided into a NAFLD group (n=71) and a non-NAFLD group (n=53). The prevalence of NAFLD was 57.2%. CAD was more prevalent in the NAFLD subgroup (60.5%) compared to the non-NAFLD subgroup (45.2%). The NAFLD subgroup had higher prevalence of hypertension, smoking, obesity (measured by BMI), central obesity (measured by waist circumference and waist hip ratio), higher HbAlc, higher triglyceride levels and lower HDL levels, and higher mean CIMT. Using binary logistic regression analysis, it was found that hypertension (p=0.013), LDL cholesterol (p=0.049), microalbuminuria (p=0.034) and NAFLD (p=0.016) were significantly correlated with CAD.
  
  
  CONCLUSIONS
  Among type 2 diabetics, NAFLD clusters with traditional coronary risk factors. It is a surrogate and fairly reliable marker of risk for CAD amongst type 2 diabetic patients. Ultrasonographically detected NAFLD is a simple, cheap, and safely assessable parameter for coronary risk stratification in type 2 diabetics.
