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

- Other: Medication history
- Registration Number
- NCT05685888
- Brief Summary
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.

Group Intervention Description The non-Ursodeoxycholic acid (non- UDCA) group Medication history The non-Ursodeoxycholic acid (non- UDCA) group was defined as individuals who didn't received regular Ursodeoxycholic acid treatments during the two weeks before diagnosed as COVID-19 infection. Subjects matching the characteristics of this group were screened from the database according to inclusion and exclusion criteria, and characteristics of this group were collected and recorded for subsequent analysis. The Ursodeoxycholic acid (UDCA) group Medication history The Ursodeoxycholic acid (UDCA) group was defined as individuals who have received regular Ursodeoxycholic acid treatments during the two weeks before diagnosed COVID-19 infection (The frequency and dosage of UDCA were also recorded). Subjects matching the characteristics of this group were screened from the database according to inclusion and exclusion criteria, and characteristics of this group were collected and recorded for subsequent analysis.

- Secondary Outcome Measures
Name Time Method The impact of UDCA on the rate of severe illness, hospitalization rate and recovery time of COVID-19 From January 1,2022 to December 31,2022 Protective effects (The Infection rate of COVID-19) of UDCA (different doses) From January 1,2022 to December 31,2022 Protective effects (The Infection rate of COVID-19) of UDCA in different cohorts (different ages, different immunosuppressants) From January 1,2022 to December 31,2022
