ABSTRACT
The present study was undertaken to establish the aetiology and prognostic factors of liver failure in central India. Of the 122 cases of hepatic failure 95 (78%), 19 (15.5%) and 8 (6.5%) were labelled as fulminant hepatic failure (FHF), chronic hepatic failure (CHF) and subacute hepatic failure (SAHF) respectively. Hepatitis E virus (HEV) and hepatitis B virus (HBV) were aetiological agents amongst 41% (n = 39) and 37% (n = 35) patients with FHF respectively. Mixed infection among such cases even though observed was infrequent and 15% (n = 14) of FHF did not have any serological markers. They were presumed to be due to non A-E viral infection. Thirty-one (33%) of the FHF patients were pregnant and 29 (94%) of them were due to HEV. Amongst patients with SAHF and CHF, HBV and HCV were important aetiological agents. The static prognostic risk factors noted in the present study are age above 40 years, presence of identifiable viral aetiology (A to E), alcoholic status in males and pregnancy particularly in the third trimester or postpartum state. Among the dynamic factors, bilirubin level above 20 mg/dl and prothrombin time over 20 seconds appeared to be the risk factors.
