Abstract

Background/aims: India is hyper-endemic for hepatitis E virus (HEV). HEV infection in cirrhosis may cause high mortality. Prospective study evaluating HEV infection in cirrhotics is scarce.

Methods: Consecutive patients with cirrhosis and healthy controls were included. Cirrhotics were categorized to 3 groups, (Group I - rapid decompensation, Group II - chronically decompensated, Group III - cirrhotics without decompensation). Sera from cirrhotics and controls were tested for HEV-RNA (RT-PCR). HEV-RNA positivity among cirrhotics and controls was compared. Natural course and mortality rate between HEV infected and non-infected cirrhotics were assessed during a 12-month follow-up.

Results: 107 cirrhotics and 200 controls were included. 30 (28%) cirrhotics and 9 (4.5%) controls had detectable HEV-RNA (p<0.001). HEV- RNA positivity among Group I (n=42), II (n=32) and III (n=33) cirrhotics was 21 (50%), 6 (19%) and 3 (10%), respectively (p=0.002). 70% (21/30) with HEV infection and 27% (21/77) without it had rapid decompensation (p=0.001). Mortality between HEV infected and non-infected cirrhotics at 4 weeks (43% vs. 22%, p=0.001) and 12 month (70% vs. 30%, p=0.001) was different. Multivariate analysis identified HEV infection, Child-Pugh's score, renal failure, and sepsis as independent factors for mortality.

Conclusions: In India, cirrhotics were prone to HEV infection, which was associated with rapid decompensation and death.
