AbstractAt its onset, the coronavirus disease 2019 (COVID-19) pandemic brought significant challenges to healthcare systems, changing the focus of medical care on acute illness. Disruptions in medical service provision have impacted the field of viral hepatitis, with screening programs paused throughout much of 2020 and 2021. We performed a retrospective study on consecutive outpatients with COVID-19 during the second and third wave of COVID-19 in Romania, from November 2020 to April 2021, aiming to characterize the prevalence of undiagnosed hepatitis B virus (HBV) infection among patients presenting with acute illness. Overall, 522 patients had available records during the study timespan. Their mean ± standard deviation age was 51 ± 13 years; 274 (52.5%) were male. We identified 16 (3.1%) cases of active HBV infection; only six of these patients were aware of their HBV status, and 3 of the newly diagnosed cases were identified as candidates for HBV treatment. A total of 96 patients (18.4%) had serological markers suggestive for prior HBV vaccination. A large proportion of patients (n = 120, 23.0%) had positive HBV core antibodies; among these, 90 (17.2%) had cleared a previous HBV infection (being positive for HBV surface antibodies and HBV core antibodies). We identified the following parameters that were significantly more frequent in patients with a history of HBV infection: older age (P < .001), hypoalbuminemia (P = .015), thrombocytopenia (P < .001), thrombocytopenia followed by thrombocytosis (P = .041), increased blood urea nitrogen (P < .001) and increased creatinine (P = .011). In conclusion, the COVID-19 pandemic has taught us essential lessons about the importance of maintaining access to screening programs and of ensuring active monitoring of patients with chronic infections such as hepatitis B, even during a medical crisis.Copyright © 2022 the Author(s).
