Effect of Ursodeoxycholic Acid on Preventing Covid-19 Infection in Patients With Organ Transplantation

Ursodeoxycholic acid is a clinically approved drug which widely used in patients with chronic liver diseases, especially liver transplantation. In China, the COVID-19 infection is in an epidemic state, and the population is generally susceptible to COVID-19. More attention needs to be paid to the prevalence and severity of people taking immunosuppressants after organ transplantation. Recent cohort studies and experiments based on tissue cells, animals and human beings suggest that ursodeoxycholic acid has the potential ability to prevent the entry of COVID-19 into cells, revealing that Ursodeoxycholic acid may be used to prevent the COVID-19 infection. Based on the medical records of patients( already registered on the management website http://www.cltr.org or www.csrkt.org.cn) who received organ transplantation in the First Affiliated Hospital of Xi'an Jiaotong University and the First Affiliated Hospital of Zhengzhou University, this project intends to collect information and data from patients received organ transplantation, aim to understand the COVID-19 infection and severe condition of organ transplantation patients, also explore whether ursodeoxycholic acid has preventive and therapeutic effects on COVID-19 infection and severity rate in patients. This research provides a theoretical basis for further standardizing the prevention and treatment of COVID-19 in patients received organ transplantation.
