Background: Bacterial infection in early period after liver transplant (LT) is the main cause of morbidity and mortality; however, data on children is limited.
Methods: To investigate the frequency, characteristics, and the associated factors of bacterial infection during hospitalization after LT, we prospectively enrolled all consecutive children with LT for a one-year, case-control study at the unique referral center of pediatric LT in Iran.
Results: Eighty-five events of bacterial infection were detected among 51 out of 94 LT recipients (54.3%) (infection group). Forty-three patients without bacterial infection constituted the control group. The frequency of bacterial infection based on the 51 microbiologically documented events was 31.9% (30 out of 94 patients). Major site of bacterial isolation were abdomen (43.6%). The following variables were associated with bacterial infection in univariate analysis: younger age (5.6 vs 8.9 years old), longer duration of JP Drain (13.4 vs 6.3 days), central venous catheter (14.6 vs 7.6 days), and Foley catheter insertion (7.3 vs 4.5 days), reoperation (57% vs 12% of patients), mean frequency of reoperation (1.1 vs 0.1 times), and intensive care unit stay (12.1 vs 6.5 days). In multivariate analysis, only longer hospital stay after transplant (23.6 vs 10.9 days) was independently associated with bacterial infection. All ten deaths occurred within the infection group and half of which directly caused by infection.
Conclusions: These infections were associated with longer hospital stay and higher mortality rate. Conducting further studies with larger sample size and investigating more effective prophylactic measures should be considered in future studies.
