Summary

This is a two-way (retrospective+prospective) cohort study of patients with primary biliary cholangitis (PBC) and autoimmune hepatitis (AIH) infected with COVID-19. Enrolled PBC and AIH patients in clinical diagnosis and treatment at Beijing Ditan Hospital affiliated with Capital Medical University from January 2021 to December 2023. After enrollment, collect the demography data of patients, the treatment information of PBC and AIH patients, the use of ursodeoxycholic acid (UDCA) and immunosuppressants, COVID-19 vaccination, COVID-19 infection and incidence, clinical symptoms, clinical biochemistry, liver imaging, lung imaging, COVID-19 nucleic acid, COVID-19 antibody, and the incidence and treatment information of COVID-19 from January 2022 to pre enrollment. After enrollment, the corresponding treatment and clinical observation of PBC and AIH were continued, and the occurrence and incidence of COVID-19 infection were observed. For patients with COVID-19 infection during the prospective observation period, COVID-19 infection, onset and treatment were observed, including clinical symptoms, signs, heart, lung imaging, COVID-19, clinical biochemistry, disease degree, virus negative, hospital stay and prognosis. To compare the difference of COVID-19 infection rate, disease severity, clinical biochemical indicators, hospital stay and prognosis between UDCA treated and non UDCA treated patients, and to study the impact of UDCA on the occurrence, incidence and prognosis of COVID-19 infection.

Detailed description

This is a two-way (retrospective+prospective) cohort study of patients with primary biliary cholangitis (PBC) and autoimmune hepatitis (AIH) infected with COVID-19. Enrolled PBC and AIH patients in clinical diagnosis and treatment at Beijing Ditan Hospital, Capital Medical University from January 2021 to December 2023. After enrollment, the demography data of patients, the treatment information of PBC and AIH patients, the use of ursodeoxycholic acid (UDCA) and immunosuppressants, COVID-19 vaccination, COVID-19 infection and incidence, clinical symptoms, clinical biochemistry, liver imaging, lung imaging, COVID-19 nucleic acid, COVID-19 antibody, and the incidence and treatment information of COVID-19 from January 2022 to pre enrollment were collected. Meanwhile, the corresponding treatment and clinical observation of PBC and AIH were continued, and the occurrence and incidence of COVID-19 infection were observed. For patients with COVID-19 infection during the prospective observation period, COVID-19 infection, onset and treatment were observed, including clinical symptoms, signs, heart, lung imaging, COVID-19, clinical biochemistry, disease degree, virus negative, hospital stay and prognosis. This study is aim to compare the difference of COVID-19 infection rate, disease severity, clinical biochemical indicators, hospital stay and prognosis between UDCA treated and non UDCA treated patients, and to study the impact of UDCA on the occurrence, incidence and prognosis of COVID-19 infection.
