Study of Prevalence of Nonalcoholic Fatty Liver Disease in Type II Diabetes Mellitus Patients and Variations in Liver Enzymes and Lipid Profile in Diabetic Patients with Fatty Liver in Comparison With Patients Without Fatty Liver

Abstract
Background: Type 2 diabetes mellitus (T2DM) patients potentially are at risk of developing non-alcoholic fatty liver disease (NAFLD), Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease in developing and developed countries, Global prevalence of NAFLD is 25.24% with highest prevalence in the Middle East and South America and lowest in Africa.
Aim of Study: This study aimed to determine the prevalence of NAFLD among T2DM patients, diagnosed by ultrasonog-raphy of liver, to study the age, sex in NAFLD and to compare liver enzymes and lipid profile between individuals with NAFLD and without NAFLD.
Patients and Methods: A prospective study was conducted of 100 type 2 diabetic Patients visited a private clinic in Aden republic of Yemen, in the period from October 2017 to June 2018.
Results: Total of (100 patients) type 2 diabetes mellitus ambulatory patients were selected for the study. 62 patients (62%) had NAFLD and 38 patients (38%) had normal liver on ultrasonography, the prevalence of NAFLD in the present study was 62%, Majority of the study population observed with type 2 diabetes mellitus and NAFLD were females (n=40, 65%), and 22 were males (35%), the age range of diabetic patients with NAFLD was 40-65 years, mean age 53.16 SD ±7.64, Subjects with diabetes mellitus and NAFLD had sig-nificant elevation in Alanine transaminase (ALT), cholesterol, LDL, and triglyceride than diabetic subjects without NAFLD.
Conclusions: Early detection and optimum control of diabetes mellitus is important to minimize the effect of diabetes on liver. Hence, assay of serum levels of hepatic enzymes, and abdominal ultrasound to detect NAFLD should be done in all patients with T2DM as preliminary diagnostic tests.
