Item Prevalence and risk factors for metabolic syndrome among aging adults in an urban Sri Lankan population(Sri Lanka Medical Association, 2015) Kasturiratne, K.T.A.A.; Niriella, M.A.; de Silva, S.T.; Perera, K.R.; Subasinghe, S.K.C.E.; Kodisinghe, S.K.; Piyaratna, T.A.C.L.; Vithiya, K.; Kottachchi, D.; Ranawaka, U.K.; Jayasinghe, C.; Rajindrajith, S.; Dassanayake, A.S.; de Silva, A.P.; Pathmeswaran, A.; de Silva, H.J.INTRODUCTION AND OBJECTIVES: Metabolic syndrome (MetS) is assumed to be of high prevalence in the Asian region. However, its community prevalence and risk factors in South Asia is poorly studied. We determined the prevalence and risk factors for MetS among adults in an urban Sri Lankan population. METHOD: The study population consisted of 42-71 year old adults, selected by stratified random sampling from the Ragama Medical Officer of Health area. MetS was defined by the International Diabetic Federation criteria with ethnic specific cutoffs. Anthropometric measurements, blood pressure (BP) and body fat distribution estimates were made. Glycosylated hemoglobin, fasting serum lipids, serum alanine aminotransferase (ALT) and serum creatinine (SCr) with estimated glomerular filtration rate (eGFR) were determined. CKD was defined as GFR<60ml/min/1.72m2 (KDIGO/KDOQI classification), USS abdomen was performed to detect fatty liver and non-alcoholic fatty liver disease (NAFLD) was diagnosed on safe alcohol consumption (< 14 units/week for men, < 7 units/week for females) and absence of hepatitis B and C markers. RESULTS: 2155 (1244 [57.7%] women, mean age 59.2 years [SD, 7.7]) participated. 1014 (47.1%) [mean age 59.2 years (SD, 7.7), 256 (28.1%) men; 758 (60.9%) women] had MetS. On multivariate analysis female gender, abnormal total body fat and abnormal visceral fat level (>10%) and presence of NAFLD were independently associated with MetS. Age 65 or more, raised ALT and CKD were not associated with MetS. CONCLUSION: The prevalence of MetS among adults in this aging urban Sri Lankan community was high and is independently associated with female gender, abnormal body fat distribution and presence NAFLD.Item How should we manage patients with non-alcoholic fatty liver disease in 2007?(Wiley-Blackwell, 2007) Chan, H.L.; de Silva, H.J.; Leung, N.W.; Lim, S.G.; Farrell, G.C.Evidence-based management guidelines for non-alcoholic fatty liver disease (NAFLD) are lacking in the Asia-Pacific region or elsewhere. This review reports the results of a systematic literature search and expert opinions. The Asia-Pacific Working Party on NAFLD (APWP-NAFLD) has generated practical recommendations on management of NAFLD in this region. NAFLD should be suspected when there are metabolic risk factors and/or characteristic changes on hepatic ultrasonography. Diagnosis by ultrasonography, assessment of liver function and complications, exclusion of otherliver diseases and screening for metabolic syndrome comprise initial assessment. Liver biopsy should be considered when there is diagnostic uncertainty, for patients at risk of advanced fibrosis, for those enrolled in clinical trials and at laparoscopy for another purpose. Lifestyle measures such as dietary restrictions and increased physical activity (aerobic exercise) should be encouraged, although the best management strategy to achieve this has yet to be defined. Complications of metabolic syndrome should be screened for regularly. Use of statins to treat hypercholesterolemia is safe and recommended; frequent alanine aminotransferase (ALT) monitoring is not required. Obese patients who do not respond to lifestyle measures should be referred to centers specializing in obesity management; consideration should be given to bariatric surgery or gastric ballooning. The role of pharmacotherapy remains investigational and is not recommended for routine clinical practice. Non-alcoholic fatty liverdisease should be recognized as part of the metabolic syndrome and managed in a multidisciplinary approach that addresses liver disease in the context of risk factors for diabetes and premature cardiovascular disease. Lifestyle changes are the first line and mainstay of management
