Item Presence of fatty liver disease leads to unusual rise of liver enzymes in patients with common bile duct colic(Korean Association of Hepato-Biliary-Pancreatic Surgery, 2021) Uragoda, B.; Ediriweera, D.; Paranahewa, L.; Ekanayake, C.; Tillakarathna, S.; Siriwardana, R.INTRODUCTION: This study compares liver enzymes, inflammatory markers and bilirubin levels in patients with and without fatty liver disease (FLD) presenting with common bile duct (CBD) obstruction. METHODS: CBD colic was diagnosed based on clinical, radiological and biochemical criterion. Presence of FLD was diagnosed by ultra sound scan and the macroscopic appearance of liver during surgery. Liver enzymes, inflammatory markers and bilirubin levels were prospectively assessed and compared between the two groups. RESULTS: Out of 42, there were 22 (52.3%) patients with FLD. Median body mass index was 26.9 (24.1–30.8) in fatty liver group compared to 25.7 (23.5–26.2) in others. Individuals with FLD showed high aspartate transaminase (558.5 vs. 247.0, p = 0.005), alanine trasaminase (467 vs. 228.5, p = 0.005) and bilirubin (3.8 vs. 2.2, p = 0.015) levels compared to those without FLD. According to multiple linear regression models, high AST and ALT levels showed significant associations with FLD after adjusting for age, gender, body mass index, amylase and C reactive protein levels. The median enzyme level at two weeks did not show a difference among patients with and without FLD. CONCLUSIONS:Presence of FLD causes unusual rise of AST and ALT levels in patients with CBD stones. This rise is transient.Item Genetic variants of NAFLD in an urban Sri Lankan community(Wiley Blackwell Scientific Publications, 2013) Niriella, M.A.; Kasturiratne, A.; Akiyama, K.; Takeuchi, F.; Isono, M.; Dassanayake, A.S.; de Silva, A.P.; Wickremasinghe, A.R.; Kato, N.; de Silva, H.J.OBJECTIVE: Recently, genome-wide association studies (GWAS) have successfully identified loci associated with susceptibility to non-alcoholic fatty liver disease (NAFLD) in populations of European descent. No large-scale genetic studies have been performed thus far in South Asian populations. Therefore, as part of a community-based cohort study in an urban adult population of Sri Lankans, we investigated associations of genetic variants with NAFLD, diagnosed on established ultrasound criteria, and its related phenotypes. METHODS: We selected 10 single nucleotide polymorphisms (SNPs), all previously reported to be associated with NAFLD in populations of European and/or South Asian ancestry, for a case-control replication study. They included loci derived from GWAS [PNPLA3 (rs738409), LYPLAL1 (rs12137855), GCKR (rs780094), PPP1R3B (rs4240624) and NCAN (rs2228603)] plus those from candidate gene studies [APOC3 (rs2854117 and rs2854116), ADIPOR2 (rs767870) and STAT3 (rs6503695 and rs9891119)]. Genotype data of 2988 participants were used for the analysis. RESULTS: A significant NAFLD association was observed for PNPLA3 (rs738409) [OR = 1.25, 95% CI 1.08–1.44, P = 0.003)]; rs738409 was also associated with a trend towards lower serum triglycerides APOC3 variants were significantly (P = 7.3–7.5 × 10–8) associated with higher triglycerides, but not with NAFLD (OR = 0.86). Apart from SNP–lipid associations previously reported at the GCKR, PPP1R3B and NCAN loci, there were no other prominent associations. CONCLUSION: Our data confirm that the PNPLA3 gene variant is significantly associated with NAFLD in the general Sri Lankan population but could not replicate previously reported disease associations at other loci, reinforcing the importance of further large-scale study on genetic variants in diverse populations to better understand the pathophysiology of NAFLD.
