Hepatitis B and C screening in hospitalized patients with SARS-CoV-2 infection

Abstract

AimsTo evaluate the results of a hepatitis B and C screening program in hospitalized COVID-19 patients.MethodTransversal prospective study conducted in two Spanish hospitals. Patients admitted from March 1st to December 31st 2020 with a diagnosis of COVID-19 were tested for markers of hepatitis B (HBsAg, anti-HBc) and C (anti-HCV, HCV RNA) infection.ResultsIn this period, 4662 patients with COVID-19 were admitted to our centers: 56.3% were male, median age was 76 (0–104) years. Data regarding HBV infection was available in 2915 (62.5%) patients; 253 (8.75%) were anti-HBc + and 11 (0.38%) HBsAg+. From these, 4 patients did not have a previous diagnosis of hepatitis B, 7 received corticosteroids and one received prophylaxis. There was one HBV reactivation. Anti-HCV were available in 2895 (62%) patients; 24 (0.83%) were positive. From these, 13 patients had a previous hepatitis C diagnosis: 10 patients had been treated with SVR, one achieved spontaneous cure and 2 did not receive treatment. From the 11 previously unknown anti-VHC + patients, 10 had a negative HCV RNA. Overall, only 3 (0.10%) patients tested RNA HCV + . However, none received HCV treatment (2 older than 90 years with comorbidities, 1 died from COVID-19).ConclusionScreening of hepatitis C infection in hospitalized COVID-19 patients seems less useful than expected. The low prevalence of active infection after antiviral treatments and the high age of our population limit the detection of potential candidates for treatment. HBV screening should be aimed to prevent reactivation under immunosuppressive treatments.
