â¢Carbapenem-resistant Enterobacteriaceae infections in renal transplant recipients are described.â¢This was a case series of 25 urinary tract infections and 9 surgical site infections.â¢Overall, 85.29% were considered early infections.â¢Nephrotoxicity occurred in 4 (15.38%) cases.â¢Polymyxins and aminoglycosides were good therapeutic alternatives.
BackgroundCarbapenem-resistant Enterobacteriaceae (CRE) are emerging pathogens. Recent publications have shown that renal transplant recipients are a population at risk for CRE infections. Management of these infections in this population is complex, requiring frequent use of nephrotoxic antimicrobial agents. Differentiating between urinary tract infection (UTI) and surgical site infection (SSI) in renal transplant recipients is sometimes difficult. The aim of this study was to describe CRE UTIs and SSIs in renal transplant recipients and to evaluate the impact of these infections on renal graft and patient survival.ResultsBetween January 2010 and October 2015, a total of 428 renal transplants were performed; 25 UTIs and 9 SSIs were identified. Median time between transplantation and diagnosis of CRE infection was 26 days; 29 cases (85.29%) were considered early infections. Of the 34 CRE isolates, 100% were sensitive to amikacin and colistin. Polymyxins were the most commonly used antimicrobial agent (27 cases [79.41%]). Nephrotoxicity was found in 4 (15.38%) of 26 cases. Combination therapy was used in 19 cases (55.88%), with a cure rate of 74%; monotherapy was used in 15 cases (44.11%), with a cure rate of 86%. Among the 25 cases of UTI, the cure rate was 100%, and recurrence occurred in 4 cases (16%). Among the 9 cases of SSI, 7 (77.7%) had negative outcomes (nephrectomy or death).ConclusionsWe observed that CRE UTIs had a high therapeutic success rate, low recurrence, and low mortality. However, CRE SSIs were associated with high morbidity and mortality, with high graft loss. Polymyxins and aminoglycosides, despite the risk of nephrotoxicity, had little impact on renal graft function, and are thus a safe therapeutic alternative to treat these infections.
