Background and Aims: COVID-19 is a dominant pulmonary disease, with multisystem involvement, depending upon co morbidities. Its profile in patients with pre-existing chronic liver disease (CLD) is largely unknown. We studied the liver injury patterns of SARS-Cov-2 in CLD patients, with or without cirrhosis. Methods: Data was collected from 13 Asian countries on patients with CLD, known or newly diagnosed, with confirmed COVID-19. Result: Altogether, 228 patients [185 CLD without cirrhosis and 43 with cirrhosis] were enrolled, with comorbidities in nearly 80%. Metabolism associated fatty liver disease (113, 61%) and viral etiology (26, 60%) were common. In CLD without cirrhosis, diabetes [57.7% vs 39.7%, OR=2.1(1.1-3.7), p=0.01] and in cirrhotics, obesity, [64.3% vs. 17.2%, OR=8.1(1.9-38.8), p=0.002) predisposed more to liver injury than those without these. Forty three percent of CLD without cirrhosis presented as acute liver injury and 20% cirrhotics presented with either acute-on-chronic liver failure [5(11.6%)] or acute decompensation [4(9%)]. Liver related complications increased (p In decompensated cirrhotics, the liver injury was progressive in 57% patients, with 43% mortality. Rising bilirubin and AST/ALT ratio predicted mortality among cirrhosis. Conclusions: SARS-Cov-2 infection causes significant liver injury in CLD patients, decompensating one fifth of cirrhosis, and worsening the clinical status of the already decompensated. The CLD patients with diabetes and obesity are more vulnerable and should be closely monitored.

The aim of this study was to determine the association of single nucleotide polymorphism (SNP) in patatin-like phospholipase domain-containing 3 (PNPLA3) at I148 with histological severity of non-alcoholic fatty liver disease (NAFLD). Patients were selected for the study if they had histological evidence of NAFLD and clinical evidence of non-alcoholic steatohepatits (NASH) cirrhosis. We included 50 NASH cirrhosis, 99 patients of NAFLD including 36 non-NASH fatty liver (NNFL) along with 63 NASH and 75 healthy controls. PNPLA3 genotyping was done by real-time PCR using a Taqman assay for rs738409. CC, CG, and GG frequencies were 45 (60.0%)/27 (36.0%)/3 (4.0%) in healthy control, 19 (52.8%)/14 (38.9%)/ 3 (8.3%) in NNFL, 18 (28.6%)/29 (46.0%)/16 (25.4%) in NASH, and 7 (14.6%), 25 (52.1%), 16 (33.3%) in cirrhosis. The frequency of G allele was significantly higher (62.6%) in NAFLD than in healthy control. The GG genotype had 20.25 times odds of NAFLD. The GG genotype had 6.53 times odds of having NASH. HOMA-IR > 1.6 had 3.81 times odds of having NASH. Regression analysis revealed that G allele odds of having cirrhosis was 3.9 times compared to C. The G allele was also significantly associated with steatosis, lobular inflammation, NAFLD activity score, and fibrosis. PNPLA3 genotype showed an association with NAFLD, NASH, fibrosis, and cirrhosis.

Nonalcoholic fatty liver disease (NAFLD) is considered to be a disease of obese individuals, yet lean patients are increasingly susceptible to have NAFLD. The aim of this study was to evaluate the profile of nonobese patients by comparing with obese NAFLD patients. We have included 465 patients of NAFLD after exclusion of other diseases, and 220 with elevated alanine aminotransferase (ALT) were biopsied. Patients were biochemically and clinically evaluated: blood pressure, body mass index (BMI), and waist circumference (WC) were recorded for every patient. A BMI ≥ 25 kg/m2 was defined as obese, and those with a BMI of
