Abstract
Introduction: Hepatitis E virus infection can lead to severe liver disease and unregulated hepatitis in patients with a history of previous chronic liver disease of different etiologies.
Objective: To determine the seroprevalence of hepatitis E in untreated carriers of hepatitis C virus, hepatitis B virus, autoimmune hepatitis and in patients with drug-induced liver disease.
Materials and Methods: This is a cross-sectional study with a total sample of 301 outpatient hepatology volunteers. The detection of anti-HEV IgM and IgG antibodies was determined using the ELISA (RecomWell anti-HEV IgG and IgM, Mikrogen®, Germany), One-step real-time PCR was used for the detection of HEV-RNA (Taqman, Life Technologies TM, Foster City, CA, USA).
Results: The overall prevalence of anti-HEV IgG and IgM in the population studied was 12.95% and 2.3%, respectively. The prevalence by group were: anti-HEV IgG: hepatitis C virus with 13.2%, hepatitis B virus with 13%, autoimmune hepatitis with 8.1 and drug-induced liver disease with 21.1. Patients with HCV chronic hepatitis and positive HCV IgG serology showed an increase in transaminase levels in 66.7% (10/15) of the cases, while in the seronegative patients this increase was present in 42.4% (42/99) of the cases (p<0.05).
Conclusions: A high seroprevalence of HEV was observed. Among the patients with serology concomitantly positive for anti HEV IgG and IgM, 57.1% (4/7) had higher levels of TGO and TGP, suggesting acute HEV infection. A relationship between hepatitis C and E virus co-infection and elevated transaminase levels has been demonstrated. Future studies with evaluation of several clinical parameters are necessary.
