Hemophilia Liver Transplantation Observational Study

Area of Science:

• Hepatology
• Transplantation Medicine
• Infectious Diseases

Background:

• Hepatitis C virus (HCV) is a primary cause of liver disease in hemophilia patients.
• HCV/HIV coinfection accelerates liver disease progression compared to HCV monoinfection.
• Liver transplantation is sometimes necessary for patients with advanced liver disease, even with antiretroviral therapy.

Purpose of the Study:

• To compare liver transplant outcomes between hemophilic (H) and nonhemophilic (NH) candidates with HCV.
• To identify predictors of pretransplant and posttransplant survival in HCV-positive liver transplant candidates.

Main Methods:

• Retrospective observational study using the United Network for Organ Sharing (UNOS) national transplant registry.
• Analysis of 2502 HCV-positive liver transplant candidates from January 2004 to December 2010.
• Comparison of pretransplant and posttransplant survival rates between H and NH groups, including HIV-coinfected individuals.

Main Results:

• Pretransplant mortality was associated with higher MELD scores and HIV coinfection, but not hemophilia status.
• Posttransplant mortality was similar between hemophilic and nonhemophilic patients, despite lower CD4 counts in hemophilic patients.
• HIV infection significantly increased mortality risk in both hemophilic and nonhemophilic patients.

Conclusions:

• Hemophilia itself does not negatively impact liver transplant outcomes.
• HIV coinfection is a significant risk factor for mortality in liver transplant recipients with HCV.
• Liver transplant outcomes are comparable between hemophilic and nonhemophilic patients with HCV.
