    The value of brunt scoring in predicting the short term outcome of non-alcohlic steatohepatitis
    (Wiley Blackwell Scientific Publications, 2004) Hewavisenthi, S.J.de S.; Pathmeswaran, A.; de Silva, H.J.
    BACKGROUND: Brunt scoring is currently used in the grading and staging of liver biopsies in non-alcoholic steatohepatitis (NASH). Its value in predicting the outcome of patients following modifications in lifestyle, the cornerstone of management in NASH, needs evaluation. OBJECTIVES: To determine whether Brunt grades correlate with Aspartate transaminase (AST) and Alanine transaminase (ALT) levels, and outcome following lifestyle modifications in NASH. METHOD: In a prospective study from May 1999 to May 2003 the biopsies of 79 patients diagnosed as having NASH were assigned 3 necroinflammatory grades based on the Brunt system. The mean serum transaminase values at presentation for each necroinflammatory grade were compared using ANOVA. 77/79 patients were given advice on lifestyle modifications and then followed up for a median 2.5 years. The time taken for serum transaminases to return to normal was correlated with the necroinflammatory grades, AST and ALT values at presentation using Kendall tau b. RESULTS : The mean AST and ALT values (IU/L) in the three necroinflammatory grades were - grade 1:62.4 and 102:1, grade 2: 87.6 and 139.4 and grade 3: 90.9 and 164.5. There was a significant difference in the AST and ALT values between grades 1 and 2, and grades 1 and 3, but not between grades 2 and 3. In 51/77 patients serum transaminases returned to normal levels after a median 6 months (range 3– 14 months). There was no significant correlation between the time taken for serum transaminases to return to normal and the transaminase values or necroinflammatory grades at presentation. CONCLUSION: Brunt grading correlates with both AST and ALT levels. However, neither necroinflammatory grades nor serum transaminase values at first presentation are predictors of the duration to normalization of liver enzymes in NASH patients managed with life style modifications

    Prevalence of non-alcoholic fatty liver disease and its risk factors in an urban adolescent cohort in Sri Lanka
    (Sri Lanka Medical Association, 2015) Jayasinghe, Y.C.; Rajindrajith, S.; Kasturiratne, A.; de Silva, S.T.; Niriella, M.A.; Perera, K.R.; Subasinghe, S.K.C.E.; Kodisinghe, S.K.; Priyantha, T.A.C.L.; Vithiya, K.; Pathmeswaran, A.; de Silva, H.J.
    INTRODUCTION AND OBJECTIVES: High prevalence of non-alcoholic fatty liver disease (NAFLD) is reported among adults in Sri Lanka. Although limited data on childhood obesity is available, community prevalence of NAFLD and its risk factors among adolescents is unknown. We investigated the prevalence and risk factors for NAFLD in an urban adolescent birth cohort in Sri Lanka. METHODS: The study population consisted 14 year-olds, belonging to the birth cohort born in 2000, residing in the Ragama Medical Officer of Health area. NAFLD was diagnosed based on established ultrasound criteria. Anthropometric measurements, blood pressure (BP) and total body fat distribution (TBF) estimates were made. Fasting blood sugar, serum insulin, fasting serum lipid and serum alanine aminotransferase (ALT) levels were measured. Independent predictors of NAFLD were determined by multivariate analysis. RESULTS: 508 adolescents [263 (51.8%) girls] participated in the study. Overall 44 (8.7%) had NAFLD [22 (8.4%) girls]. 46 (18.8%) boys and 54 (20.5%) girls had a BMI above the equivalent of 23 kgm2in adults. 44 (17.1%) boys and 77 (29.3%) girls had elevated TBF. On multivariate analysis, having an elevated BMI [OR=10.1 (95% confidence interval: 3.9-29.2) and elevated TBF [OR=4.4 (95% confidence interval: 1.5-12.8)] were independently associated with NAFLD. CONCLUSION: The prevalence of NAFLD among adolescents in this urban Sri Lankan community is high, and is strongly associated with obesity and abnormal TBF. Despite elevated TBF being commoner in girls, we found no gender differences in prevalence of NAFLD among adolescents in this urban Sri Lankan community is strongly associated with obesity and abnormal TBF. Our findings emphasize the needs to access these risk factors through preventive and screening programs.
