Item The association between steatosis and liver damage in transfusion-dependent beta thalassaemia patients(Wiley-Blackwell, 2023) Padeniya, P.; Ediriweera, D.; de Silva, A.P.; Niriella, M.; Premawardhena, A.Non-alcoholic fatty liver disease (NAFLD) is a global health problem. Iron is the leading cause of liver damage in patients with transfusion-dependent thalassaemia (TDT), and data on the contribution of NAFLD to liver damage in TDT is lacking. Forty-five heavily transfused TDT patients who did not have biochemical or ultrasonic evidence of liver cirrhosis were evaluated for effects of iron overload, including the presence of diabetes mellitus, hypogonadism, serum ferritin, R2-MRI-liver, and liver enzymes alanine aminotransferase and aspartate aminotransferase. Liver fibrosis and steatosis were estimated using transient elastography (TE). Nine (20%) patients had significant steatosis (S1), and their body mass index (BMI) and liver fibrosis scores were higher than in patients without significant steatosis (S0) (p = 0.03 and p = 0.004, respectively). On regression analysis, the controlled attenuation parameter (CAP) score (i.e., degree of liver steatosis) was associated only with increasing BMI. The TE score (i.e., degree of liver fibrosis) was associated with increasing age, CAP score, male gender, and presence of diabetes. Neither liver steatosis nor fibrosis showed significant association with the liver iron concentration or iron-related organ damage (hypogonadism). In this cohort of TDT patients, steatosis of the liver, which is associated with increasing BMI, appeared to increase the risk of liver fibrosis.Item 'Mistakes in managing non-alcoholic fatty liver disease and how to avoid them'(Informa Health Care, 2023) Niriella, M.A.; Dassanayake, U.; de Silva, H.J.Non-alcoholic fatty liver disease (NAFLD) is the commonest cause of chronic liver disease. NAFLD is estimated to affect 25% of the global population. Therefore, it is widely encountered in primary care. A proportion of patients with NAFLD need a specialist referral, evaluation and follow-up.There have been many updated guidelines on the management of NAFLD in the past few years. Given the burden of NAFLD in the community and its cardiovascular and liver-related adverse outcomes, knowledge of evidence-based standards of care for these patients is essential for any practitioner managing patients with NAFLD. As an asymptomatic disease in the early stages, NAFLD can lead to many mistakes in its management.We aim to highlight some common mistakes in managing NAFLD and attempt to provide evidence-based recommendations.Item Recurrence of graft steatosis after liver transplantation for cryptogenic cirrhosis in recently commenced liver transplant program(Springer India, 2016) Siriwardana, R.C.; Niriella, M.A.; Dassanayake, A.S.; Liyanage, C.A.H.; Gunetilleke, B.; de Silva, H.J.Non-alcoholic fatty liver disease (NAFLD) seems to recur in at least one third of patients transplanted for non-alcoholic steatohepatitis (NASH)-related cirrhosis. While, NASH recurrence does not seem to affect overall graft and patient survival up to 10 years, cardiovascular and infection-related morbidity and mortality seem to be increased in these patients. This report looks at the graft histology in patients who were transplanted for NASH-related cirrhosis after short-term follow up. We report a high prevalence of recurrent NAFLD in liver grafts post-transplant among five patients. The degree of steatosis noted among the recipients is alarming.Item Association of genetic variants with non-alcoholic fatty liver disease in an urban Sri Lankan community(Wiley-Blackwell, 2015) Kasturiratne, A.; Akiyama, K.; Niriella, M.A.; Takeuchi, F.; Isono, M.; Dassanayake, A.S.; de Silva, A.P.; Wickremasinghe, A.R.; Kato, N.; de Silva, H.J.Item Non-alcoholic fatty liver disease among potential live liver donors-a preliminary experience from Sri Lanka(Springer India, 2014) Silva, H.; Siriwardana, R.C.; Niriella, M.A.; Dassanayake, A.S.; Liyanage, C.A.H.; Gunetilleke, B.; de Silva, H.J.No abstract availableItem Influence of non-alcoholic fatty liver disease on the development of diabetes mellitus(Wiley-Blackwell, 2013) Kasturiratne, A.; Weerasinghe, S.; Dassanayake, A.S.; Rajindrajith, S.; de Silva, A.P.; Kato, N.; Wickremasinghe, A.R.; de Silva, H.J.BACKGROUND AND AIM: Non-alcoholic fatty liver disease (NAFLD) is linked to metabolic syndrome, and is known to be associated with impaired fasting glycemia and diabetes mellitus. This prospective community-based study was conducted to determine the association between NAFLD and incidence of diabetes mellitus in an urban adult population in Sri Lanka. METHODS: Participants of the Ragama Health Study cohort were assessed for NAFLD using established ultrasound criteria in 2007. Those who were free of diabetes at baseline were followed up for 3 years. Incidence rates of diabetes mellitus were compared between subjects with and without NAFLD at baseline. RESULTS: Out of 2984 subjects, 926 had NAFLD and 676 had diabetes in 2007. Of the 2276 subjects who were free of diabetes in 2007, 1914 were re-assessed in 2010. After 3 years, 104 out of 528 subjects with NAFLD and 138 out of 1314 subjects without NAFLD had developed diabetes mellitus de novo. Incidence rates of diabetes were respectively 64.2 and 34 per 1000 person-years of follow up for those with and without NAFLD. NAFLD was an independent predictor of developing diabetes mellitus. Other independent predictors were impaired fasting glycemia and dyslipidemia. CONCLUSIONS: Subjects with ultrasonically diagnosed NAFLD have an increased risk of developing diabetes mellitus. Intervention for NAFLD through lifestyle modification may prevent progression of the current diabetes epidemic. © 2012 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.Item Non-alcoholic fatty liver disease: confronting the global epidemic requires better awareness(Wiley-Blackwell, 2009) de Silva, H.J.; Dassanayake, A.S.No Abstract availableItem Prevalence and risk factors for non-alcoholic fatty liver disease among adults in an urban Sri Lankan population(Wiley-Blackwell, 2009) Dassanayake, A.S.; Kasturiratne, A.; Rajindrajith, S.; Kalubowila, U.; Chackrewarthy, S.; de Silva, A.P.; Makaya, M.; Mizoue, T.; Kato, N.; Wickremasinghe, A.R.; de Silva, H.J.BACKGROUND AND AIMS: Non-alcoholic fatty liver disease (NAFLD) is an emerging problem in the Asia-Pacific region. However, its prevalence and risk factors in Asian (especially South Asian) communities is poorly studied. In this study, the aim was to determine the community prevalence and risk factors for NAFLD among adults in an urban Sri Lankan population. METHODS: The study population consisted of 35-64-year-old adults, selected by stratified random sampling. NAFLD was diagnosed on established ultrasound criteria for fatty liver, safe alcohol consumption (< 14 units/week for men, < 7 units/week for females) and absence of hepatitis B and C markers. Blood pressure (BP) and anthropometric measurements were made, and fasting glucose, glycosylated hemoglobin, serum lipids, fasting serum insulin and serum alanine aminotransferase (ALT) were determined. RESULTS: Of the 2985 study participants, 974 (32.6%) had NAFLD (605 [62.1%] women, mean age 52.8 years [standard deviation, 7.3]). On multivariate analysis, obesity, acanthosis nigricans, insulin resistance, elevated diastolic BP, fasting plasma glucose, plasma triglycerides, and ALT twice the upper limit of the reference range or more were independently associated with NAFLD. CONCLUSION: The prevalence of NAFLD among adults in this urban Sri Lankan community is high and is strongly associated with constituent features of the metabolic syndrome.
