Study of COVID-19 Infection and Its Clinical Prognosis in Chronic Hepatitis B Patients With Antiviral Therapy

Study Overview
=================
Brief Summary
-----------------
This is a two-way (retrospective and prospective) study of COVID-19 infection in an observational cohort of patients with chronic hepatitis B treated with antiviral therapy. Patients with chronic hepatitis B who received anti-HBV treatment in the Second Department of Hepatology, Beijing Ditan Hospital Affiliated to Capital Medical University from February 2022 to December 2023 were enrolled. After enrollment, demographic data of patients, information on antiviral treatment of chronic hepatitis B, COVID-19 vaccination, COVID-19 infection and COVID-19 incidence and treatment from January 2022 to pre enrollment, and data on HBV virus and serology, clinical biochemistry, liver and lung imaging, COVID-19 nucleic acid and COVID-19 antibody examination of patients were collected. After enrollment, prospective anti-HBV treatment, HBV virology, clinical biochemistry, liver imaging and COVID-19 infection and morbidity were observed. The patients with COVID-19 infection during the prospective observation period were observed for COVID-19 infection, onset and treatment, including body temperature, clinical symptoms, signs, cardiac examination, pulmonary imaging, COVID-19, clinical biochemistry, disease severity, time of virus negative conversion, hospital stay and outcome. The influence of COVID-19 infection on liver disease and the influence of interferon anti-HBV treatment on COVID-19 infection, its pathogenesis and prognosis were studied.

Detailed Description
-----------------
This is a two-way (retrospective+prospective) study of COVID-19 infection in an observational cohort of patients with chronic hepatitis B treated with antiviral therapy. Patients with chronic hepatitis B who received anti-HBV treatment in the Department of Hepatology Division 2, Beijing Ditan Hospital, Capital Medical University from February 2022 to December 2023 were enrolled. After enrollment, demographic data of patients, information on antiviral treatment of chronic hepatitis B, COVID-19 vaccination, COVID-19 infection and COVID-19 incidence and treatment from January 2022 to pre enrollment, and data on hepatitis B virus and serology, clinical biochemistry, liver and lung imaging, COVID-19 nucleic acid and COVID-19 antibody examination of patients were collected. After enrollment, prospective anti hepatitis B virus treatment, HBV virology, clinical biochemistry, liver imaging and COVID-19 infection and morbidity were observed. The patients with COVID-19 infection during the prospective observation period were observed for COVID-19 infection, onset and treatment, including body temperature, clinical symptoms, signs, cardiac examination, pulmonary imaging, COVID-19, clinical biochemistry, disease severity, time of virus negative conversion, hospital stay and outcome. The influence of COVID-19 infection on liver disease and the influence of interferon anti hepatitis B virus treatment on COVID-19 infection, its pathogenesis and prognosis were explored.
