A Study of Cytomegalovirus Disease Epidemiology in Pediatric and Adult Liver Transplant Recipients in China

July 21, 2023 updated by: Lin Zhong

The goal of this observational study is to learn about cytomegalovirus disease epidemiology in pediatric and adult liver transplant recipients in China. The main questions it aims to answer are:

  • The incidence of Cytomegalovirus (CMV) Infections (including clinical significant CMV reactivations and CMV Diseases) among children and adults Liver transplantation patients in China
  • All-cause Mortality (Survival probability at 1 year)
  • Incidence of Allograft Rejection. Number of subjects with allograft rejection
  • Graft Loss. Incidence of graft loss (re-transplantation)
  • Late-onset CMV Disease. Incidence of late-onset CMV disease (occurring after 100 days post-randomization) as adjudicated by end point committee
  • Bacterial Infections. Incidence of bacterial opportunistic infections
  • Major Fungal Infections. Opportunistic fungal infections
  • Major Non-CMV Viral Infections. Incidence of non-CMV viral infections We will collect demographic data of participants. All recipients and donors underwent preoperative testing for CMV pp65 antigenemia, plasma CMV DNA, and serum CMV antibody. All the recipients were followed up in a liver transplant follow-up clinic twice weekly for a month after discharge from hospital. After that, patients were followed up weekly for 3 months, fortnightly for 6 months, and monthly for 12 months.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Clinically significant CMV reactivation or CMV disease was observed within 12 months of transplantation
Time Frame: Within 22 months after liver transplantation
1. CMV reactivation: CMV-lgG is positive and any one of CMV-lgM, pp65 and CMV-DNA is positive is called CMV reactivation.
Within 22 months after liver transplantation
End of follow-up survey
Time Frame: Within 22 months after liver transplantation
We will perform a follow-up for 22 months if participant is alive and does not observed CMV reactivation.
Within 22 months after liver transplantation
Death
Time Frame: Within 22 months after liver transplantation
The participant died
Within 22 months after liver transplantation

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Loss to follow-up survey
Time Frame: Within 22 months after liver transplantation
During follow-up, if we can not connect with participant, we regard this event as loss to follow-up.
Within 22 months after liver transplantation
Participants asked to withdraw
Time Frame: Within 22 months after liver transplantation
During follow-up, participants refuse to keep this study within 22 months after liver transplantation
Within 22 months after liver transplantation
