Clinical, virological, and histologic evolution of hepatitis C virus infection in liver transplant recipients

Area of Science:

• Hepatology
• Virology
• Transplantation Medicine

Background:

• Hepatitis C virus (HCV) infection poses a significant challenge post-liver transplantation (LT).
• Understanding the evolution and impact of HCV infection in LT recipients is crucial for patient management.

Purpose of the Study:

• To prospectively evaluate the incidence, time course, and consequences of HCV infection in liver transplant recipients.
• To assess the impact of HCV infection on graft hepatitis, histologic progression, and graft survival.

Main Methods:

• Prospective study of 152 liver transplant recipients.
• Monitoring for HCV infection, graft hepatitis, fibrosis, cirrhosis, and graft loss.
• Analysis of HCV genotype and its correlation with disease severity.

Main Results:

• 29% of recipients developed HCV infection post-LT; 79% were infected with HCV genotype 1b.
• HCV infection was associated with a 66% incidence of graft hepatitis, including chronic active hepatitis and fibrosis.
• HCV-infected recipients had a significantly higher rate of graft loss (14 vs. 12, P = .007), primarily due to chronic rejection.

Conclusions:

• HCV infection post-LT does not significantly affect midterm patient survival.
• HCV infection is a major risk factor for severe graft hepatitis and increased graft loss from chronic rejection.
• HCV genotype 1b is prevalent and associated with worse histologic outcomes in LT recipients.
