Abstract:
Thirty-five patients received 42 liver homografts between February 1984 and August 1985. One or more infections developed in 23 patients (66%) some time after transplantation. An average of 2.5 infections per infected patient occurred. Of 37 bacterial infections, two thirds were either bacteremias or localized intra-abdominal infections. The median onset was 29 days after operation. Thirteen viral infections were identified, with a median onset of 18 days after operation. Nine fungal infections, six disseminated and three localized, were identified, with a median onset of nine days after operation. Infection was the primary cause of death in five (14%) of 35 patients. Fatal infections were evenly distributed among bacterial (two), fungal (three), and viral (two) pathogens. Despite advances in surgical techniques and the use of cyclosporine, infection after orthotopic liver transplantation is a serious problem. Certain patients can be identified as high risks for infection and require an aggressive diagnostic workup followed by early institution of antimicrobial therapy.
Insights
Liver transplant recipients frequently experience infections, with 66% of patients developing complications. Early diagnosis and treatment are crucial for managing these serious post-transplant infections.
Area of Science:
- Hepatology
- Transplantation Immunology
- Infectious Diseases
Background:
- Liver transplantation is a complex procedure with significant risks.
- Post-transplant infections remain a major challenge in patient outcomes.
- Advances in surgical techniques and immunosuppression have not eliminated infection risks.
Purpose of the Study:
- To analyze the incidence, types, and outcomes of infections following orthotopic liver transplantation.
- To identify the common pathogens and their onset timing post-transplant.
- To underscore the significance of infection as a cause of mortality.
Main Methods:
- Retrospective analysis of 35 patients who underwent 42 liver homografts between February 1984 and August 1985.
- Categorization and tracking of bacterial, viral, and fungal infections.
- Assessment of infection-related mortality.
Main Results:
- 66% of patients (23/35) developed one or more infections post-transplantation.
- An average of 2.5 infections per infected patient was observed.
- Bacterial infections (bacteremias, intra-abdominal) had a median onset of 29 days; viral infections at 18 days; fungal infections at 9 days.
- Infection was the primary cause of death in 14% (5/35) of patients, with fatal infections distributed among bacterial, fungal, and viral pathogens.
Conclusions:
- Infection remains a serious complication after orthotopic liver transplantation, despite advancements.
- Identifying high-risk patients for aggressive workup and early antimicrobial therapy is essential.
- Proactive management strategies are necessary to mitigate infection-related morbidity and mortality.
