ABSTRACT
INTRODUCTION:
The seroprevalence of hepatitis E virus (HEV) in patients with chronic liver disease (CLD) is little known in Brazil. Studies have suggested that HEV may harmfully influence the course of CLD, with a higher risk of progression to cirrhosis.OBJECTIVE:
To estimate the prevalence of the anti-HEV antibody (IgG) in patients with CLD and to describe demographic data and risk factors, as well as clinical-laboratory and ultrasound parameters. PATIENTS ANDMETHODS:
Cross-sectional study that included 227 patients with CLD followed at a referral outpatient clinic from June 2022 to March 2023. The patients were investigated clinically and tested for liver functions, anti-HEV IgG and, in positive cases, for HEV-RNA. Ultrasonography of the upper abdomen was also carried out.RESULTS:
Investigation of 227 patients (50 with hepatitis B, 49 with nonalcoholic fatty liver disease, 33 with hepatitis C, 17 with alcoholic liver disease, 16 with schistosomiasis and 62 with mixed disease), 55.5% were female, with an average age of 57 ± 13 years; 37.9% had liver cirrhosis. Seven patients (3.08%) presented anti-HEV positive and HEV-RNA negative. Ultrasound identified association between anti-HEV and contact with pigs, presence of gynecomastia or palmar erythema, lower platelet count, higher APRI and FIB-4 values, and splenomegaly.CONCLUSION:
Although the prevalence of anti-HEV in patients with CLD was low in this study, the antibody was observed more frequently in cases with a history of contact with pigs and with clinical-laboratory or imaging evidence of more advanced chronic liver disease.Palabras clave
