Infectious Complications After Liver Transplantation

Area of Science:

• Hepatology
• Transplant Surgery
• Infectious Diseases

Background:

• Orthotopic liver transplantation (OLT) is a vital treatment for decompensated cirrhosis and hepatocellular carcinoma.
• High survival rates post-OLT are attributed to potent immunosuppressive agents.
• Immunosuppression increases susceptibility to de novo and reactivated infections.

Purpose of the Study:

• To review the causes of infection following OLT.
• To discuss therapies for managing post-OLT infectious complications.

Main Methods:

• Review of literature on infections after OLT.
• Analysis of infection timing and types relative to immunosuppression levels.

Main Results:

• Infections in the first month post-OLT are typically nosocomial or donor-derived.
• Opportunistic infections (e.g., Aspergillus) and latent infections (e.g., Mycobacterium tuberculosis) are more common 1-6 months post-OLT.
• Infections occurring later resemble those in the general population as immunosuppression is reduced.

Conclusions:

• Screening and prophylactic antimicrobial therapy reduce opportunistic infections post-OLT.
• Understanding infection patterns is crucial for effective management after liver transplantation.
• This review details infection causes and treatment strategies for OLT recipients.
