Contamination of preservation fluid (PF) has been associated with donor-transmitted infection in renal transplantation. Despite the infectious morbidity in simultaneous pancreas-kidney transplantation (SPKT), the role of PF contamination has never been evaluated.
Objective of the study:
To analyze the impact of PF contamination on bacterial infections in SPKT recipients.
Patients and methods:
We retrospectively reviewed 75 SPKT performed in our centre between 2007 and 2010, whose PF were systematically analysed. A systemic venous drainage and enteric drainage for exocrine secretions were performed for all pancreas transplants. We examined the incidence of first bacterial infections within the first three months after transplantation. A multivariate Cox survival model was used to assess the impact of contaminated PF on infection risk.
A total of 30 out of 75 (40%) patients presented with at least one infection. The incidence of infection at 3 months was 6.6 per 1000 patient-days. Infection sites were predominantly intra-abdominal and urinary (30% and 26.7%, respectively). The most common bacteria were gastrointestinal (44.4%). PF cultures were positive in 27 (36%) kidney grafts and 38 (50.7%) pancreas grafts. Overall 19 (25.3%) recipients had positive cultures in both kidney and pancreas PF samples, with similar bacteria in 13 (18.3%) patients. There was no difference between the incidence of post-transplant infections at 1 and 3 months in the group with a contaminated PF compared to the group with a sterile PF (P >0.8).In multivariate analysis pancreatic fistula was significantly associated with early bacterial infection (HR = 3.95, 95% CI [1.66-9.04], p = 0.002). No association was found between positive PF and early bacterial infection (HR = 0.99 95% CI [0.47-2.08], p = 0.97).
In SPKT, a positive PF was not associated with early bacterial infections. Pancreatic fistula appears to be a significant risk factor for early bacterial infections.
