Infection in solid organ transplantation.

Area of Science:

• Transplant medicine
• Infectious diseases
• Immunology

Background:

• Infection significantly impacts organ transplant outcomes, with high attributable mortality from fungal and cytomegalovirus diseases.
• Key infection determinants include environmental exposures, latent infections in donors or recipients, and altered immunosuppression.
• Despite progress in managing infections like cytomegalovirus and Pneumocystis carinii, significant challenges persist.

Purpose of the Study:

• To review the impact of infections on organ transplant recipients.
• To highlight advancements in infection recognition, prevention, and treatment.
• To identify future research priorities in transplant infectious disease management.

Main Methods:

• Literature review of infection determinants and outcomes in organ transplantation.
• Analysis of mortality data for specific infections.
• Synthesis of current knowledge on prevention and treatment strategies.

Main Results:

• Invasive fungal disease and cytomegalovirus disease cause 50% and 30% attributable mortality, respectively.
• Improvements in managing cytomegalovirus and P. carinii infections have been noted over the past two decades.
• Ongoing challenges include invasive mold infections, hepatitis B and C management in liver transplant recipients, and prevention of post-transplant lymphoproliferative disease.

Conclusions:

• Infection remains a critical factor influencing organ transplant success.
• Continued research is essential for addressing emerging infectious threats and improving long-term transplant outcomes.
• Focus on invasive mold infections, viral hepatitis management, and lymphoproliferative disease prevention is crucial for future advancements.
