title: Histological scoring and associated risk factors of non-alcoholic fatty liver disease.
abstract: Non alcoholic steatohepatitis is a hepatic disorder with histological features of alcohol induced liver disease that occurs in individual who do not consume significant alcohol. Liver biopsy is an important part of the evaluation in term of both grade & stage. A cross sectional study was carried out in the department of Pathology, Dhaka Medical College, Dhaka & department of Hepatology, Bangabandhu Sheikh Mujib Medical University (BSMMU) from July 2007 to June 2009. Total 55 adult subjects of both sex were included on the basis of predefined inclusion & exclusion criteria in this study to evaluate the histological pattern of non alcoholic fatty liver disease (NAFLD) and its correlation with risk factors. Liver biopsy was done and H & E and Masson's Trichrome stain slides were examined to evaluate the grade and stage of NAFLD. Scoring and semiquantitative assessment of steatosis and NAFLD severity was done according to Kleiner scale known as NAFLD activity score (NAS). The results of Pearson correlation showed only BMI and triglyceride level significantly correlated with NAS score. The results of Spearman's rank correlation showed that BMI, central obesity, triglyceridaemia and age significantly correlated with staging of fibrosis. The results of multiple regression analysis showed that variation of NAS depend on BMI and triglyceride level. The study also revealed that risk factors contributed about 29% risk for the occurrence of non alcoholic steatohepatitis.
