A Cohort Study on the Pathogen Spectrum of Liver Transplant Recipients Complicated With Infection

Liver Transplantation Clinical Trial

Official title: A Multicenter Prospective Clinical Cohort Study on the Pathogen Spectrum of Liver Transplant Recipients Complicated With Infection

Status Not yet recruiting

Clinical Trial Summary

The goal of this observational study is to map the pathogen profile of secondary infections in liver transplant recipients, to correlate the basic immune status with the characteristics of the secondary infection pathogen profile, and to establish an early warning system for monitoring secondary infections, so as to explore safe and effective therapeutic modalities to further reduce the morbidity and mortality of liver failure. The main questions it aims to answer are:

• Characterize the distribution of pathogenic bacteria infecting liver transplant recipients.

• Establish a monitoring and early warning system for secondary infections.

Clinical Trial Description

Liver transplantation is recognized as the most effective treatment for end-stage liver disease, and China's liver transplantation technology has reached the international level, with survival rates of 90%, 80%, and 70% at 1, 5, and 10 years after surgery, respectively. During the perioperative period of liver transplantation, transplant recipients with preoperative organ dysfunction, high surgical trauma, postoperative application of immunosuppressive drugs, and low anti-infective capacity are highly susceptible to associated infections, which are more likely to occur than in other transplant recipients, and have become an important factor affecting the prognosis of liver transplantation. Foreign studies reported that 18% of postoperative liver transplantation deaths were caused by infections, of which bacterial infections were the most common, followed by viral and fungal infections. In the first month after liver transplantation, the incidence of infection is the highest, and bacterial pneumonia is the most common infection, with a high case fatality rate, and the hospitalization time of the patient is significantly prolonged, and the economic expenditure is increased. Early clarification of the type and distribution of pathogenic bacteria infecting liver transplant recipients and prompt initiation of appropriate anti-infective therapy are essential to improve the survival of liver transplant recipients. ;
