2401. Epidemiology of Clostridium difficile Infection in Intestinal and Multivisceral Transplant Patients at a Single Transplant Center

BACKGROUND: Clostridium difficile infection (CDI) is the leading cause of infectious diarrhea in the healthcare setting. Solid-organ transplant (SOT) recipients are at increased risk compared with the general hospitalized population (7.4–20% vs. 0.9%). Our center recently expanded its intestinal and...

Sumario:BACKGROUND: Clostridium difficile infection (CDI) is the leading cause of infectious diarrhea in the healthcare setting. Solid-organ transplant (SOT) recipients are at increased risk compared with the general hospitalized population (7.4–20% vs. 0.9%). Our center recently expanded its intestinal and multivisceral transplant (IMVT) program, providing the opportunity to examine the epidemiology of CDI in this vulnerable population. METHODS: We conducted a retrospective study of all IMVT recipients between 2009 and 2018. CDI was defined as presence of diarrhea with a positive polymerase chain reaction (PCR) test for the toxin B gene. Early CDI constituted an episode of CDI within the first 6 months post-transplant. Data were collected on demographics, transplant characteristics, CDI episode, and outcomes. RESULTS: We identified 86 patients who underwent a total of 94 transplants: 60 (64%) isolated intestinal transplants, 21 (22%) intestine/liver/pancreas, 10 (11%) intestine/pancreas, two (2%) intestine/liver/pancreas/kidney, and one (1%) intestine/kidney transplant. All but three patients received perioperative metronidazole. Four patients (5%) had CDI prior to transplant, but none of them recurred in the first 6 months post-transplant. Five patients developed a total of seven mild-moderate episodes of early CDI (attack rate = 5.9%). Three patients (60%) with early CDI developed rejection, similar to the incidence (70%) in patients without CDI. Two patients with early CDI developed recurrence; both underwent intestinal re-transplantation. One-year mortality was similar among patients with and without early CDI (20% vs. 23%). CONCLUSION: CDI is associated with allograft loss, rejection, and mortality in some SOT recipients. Although limited by sample size, we observed that early CDI was not associated with those outcomes in our population. Multicenter studies are merited to explore risk factors for CDI and associations with outcomes in IMVT.
