Abstract:
During LTX, there may be a risk that pathogens of the native liver are released into the systemic circulation. No investigations on incidence/spectrum of pathogens in native livers have been published. We hypothesized that pathogens are found in the native liver of a large proportion of pediatric patients during LTX and investigated the microbiology of native livers. These data may help optimize antibiotic therapy. Twenty-two consecutive pediatric patients (median age 14 months, range, 5 months-15 yr) receiving LTX in our department from October 2010 to October 2011 were included in this prospective study. Tissue and bile were collected from the explanted liver and were cultivated on different media. All liver tissues were investigated using a broad-range PCR (SepsiTest(®)). In 16 patients, blood cultures were collected post-transplantation. Eleven patients (50%) had at least one pathogen detected; nine of these patients had an underlying diagnosis of biliary atresia. SepsiTest(®) was positive in seven patients. In four patients it was the only test detecting any pathogen. In detail, the positivity rate for liver tissue in all patients was 41% (n = 9); for bile 25% (n = 3); and for blood 25% (n = 4). Thirteen different pathogens (69% bacterial, 31% fungal) were isolated. A highly-sensitive broad-range PCR appears to be an effective method to detect pathogens in native livers of patients undergoing LTX. A high number and variety of microbes, including a high proportion of fungal pathogens, were detected.
Insights
Pathogens are frequently found in the native livers of pediatric patients undergoing liver transplantation (LTX). A broad-range PCR detected diverse microbes, including fungi, in 50% of patients, aiding antibiotic therapy optimization.
Area of Science:
- Hepatology
- Microbiology
- Transplant Surgery
Background:
- Liver transplantation (LTX) carries a risk of native liver pathogen release into circulation.
- Limited data exist on the incidence and spectrum of pathogens within native livers before LTX.
- Understanding native liver microbiology is crucial for optimizing peri-transplant antibiotic strategies.
Purpose of the Study:
- To investigate the prevalence and types of pathogens in native livers of pediatric patients undergoing LTX.
- To evaluate the utility of broad-range PCR for pathogen detection in this context.
- To inform antibiotic stewardship in pediatric liver transplant recipients.
Main Methods:
- Prospective study of 22 pediatric patients undergoing LTX.
- Collection and cultivation of explanted liver tissue and bile samples.
- Broad-range PCR (SepsiTest®) analysis of liver tissues.
- Post-transplant blood cultures in 16 patients.
Main Results:
- Pathogens were detected in 50% of patients (11/22); biliary atresia was common in positive cases (9/11).
- Broad-range PCR identified pathogens in 7 patients, being the sole positive method in 4.
- Positivity rates: liver tissue 41%, bile 25%, blood cultures 25%.
- Thirteen distinct pathogens isolated (69% bacterial, 31% fungal).
Conclusions:
- A significant proportion of pediatric patients harbor pathogens in their native livers prior to LTX.
- Highly sensitive broad-range PCR is effective for detecting diverse pathogens, including fungi, in native liver explants.
- These findings support the need for tailored antibiotic protocols in pediatric liver transplantation.
