Hepatitis C infection in transplantation

Area of Science:

• Hepatology
• Transplant Medicine
• Virology

Background:

• Hepatitis C virus (HCV) infection is a leading cause of end-stage liver disease and a common indication for liver transplantation.
• HCV recurrence post-transplantation is nearly universal in patients with pre-transplant viremia.
• Acquired HCV infection, though less common, is significant in populations with inadequate screening.

Purpose of the Study:

• To review the role and impact of HCV in the transplant setting.
• To analyze the natural history and outcomes of HCV infection after various solid organ and bone marrow transplantation.
• To highlight knowledge gaps and future research directions regarding HCV in transplant recipients.

Main Methods:

• Review of existing literature on HCV infection in liver, kidney, heart, lung, and bone marrow transplant recipients.
• Analysis of data regarding HCV recurrence, disease progression, and impact on graft and patient survival.
• Identification of factors influencing post-transplant HCV disease severity and outcomes.

Main Results:

• HCV recurrence is almost universal after liver transplantation in viremic patients.
• Post-transplant HCV infection may increase the risk of liver disease and complications, but its effect on survival is controversial and appears minor in short-term follow-up (5-10 years).
• Kidney, heart, lung, and bone marrow transplant recipients with HCV generally do not experience major mortality from the infection within the first decade post-transplant.

Conclusions:

• While HCV recurrence is common, its long-term impact on graft and patient survival after transplantation requires further investigation.
• Identifying factors contributing to disease progression and developing effective eradication therapies are critical unmet needs.
• More extensive long-term follow-up and detailed studies are essential to fully understand HCV's role in transplant outcomes.
