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.

Outcome Measures

Primary Outcomes (1)

  • The impact of UDCA on the Infection rate of COVID-19

    Effect of UDCA on the prevalence and severity of COVID-19 infection in transplantation patients

    From January 1,2022 to December 31,2022

Secondary Outcomes (3)

  • 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

Study Arms (2)

The Ursodeoxycholic acid (UDCA) group

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.

Other: Medication history

The non-Ursodeoxycholic acid (non- UDCA) group

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.

Other: Medication history

Interventions

The study was retrospective and did not involve the application of interventions

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Adult patients who underwent liver or renal transplantation from January 1st, 2015, to December 31st, 2022, were retrospectively identified using the database from national transplantation register website and clinical data from the First Affiliated Hospital of Xi'an Jiaotong University and the First Affiliated Hospital of Zhengzhou University.

You may qualify if:

  • \. Age ≥ 18 years; 2. Patients received liver or renal transplantation from 2015 to 2022

You may not qualify if:

  • Age \< 18 years; 2. Multi-organ transplantation; 3. Patients with incomplete information or loss of follow-up; 4.COVID-19 infection before organ transplantation; 5. Patients hospitalized with rejection or other infection within two weeks before COVID-19 diagnosis.
