Abstract

BACKGROUND:

Fungal infections are an important cause of morbidity and mortality after small bowel transplantation (SBT). Little information about risk factors for Candida infections in pediatric SBT is available.

METHODS:

We performed a 1:1 matched retrospective case-control study including 23 Candida culture-positive patients (cases) and 23 culture-negative patients (controls), matched based on age and time of transplantation. Patients' characteristics were compared using Wilcoxon rank-sum, χ, or Fisher exact tests. McNemar test was used to assess discordance between pretransplant and posttransplant fungemia. Univariate and multivariable conditional logistic regression analyses were performed to identify risk factors.

RESULTS:

The median age of the group was 1.87 years (range, 0.87-17.60); 59% patients were male. Within 1 month before transplant, 8.7% cases had fungemia and within 1-6 months before transplant, 30.4% cases had fungemia, compared with 69.6% within the 12 months after transplantation (P = 0.0001 and P = 0.02). By univariate analysis, total parenteral nutrition (TPN) (odds ratio [OR], 17.0 [95% confidence interval: 2.12, 2198]; P = 0.003) and antibiotic administration (OR, 18.99 [2.42, 2449]; P = 0.002) were risk factors for fungal infections. By multivariable analysis, both remained independent risk factors (TPN: OR, 10.86 [1.23, 1425], P = 0.03; antibiotic administration: OR, 12.83 [1.52, 1672], P = 0.01).

CONCLUSIONS:

Fungemia was significantly more frequent after SBT than before transplantation. Patients receiving TPN and antibiotic treatment had, respectively, 11 and 13 times higher risk of developing Candida infections after SBT.
