RESUMO
BACKGROUND: Renal transplant (RT) recipients are especially susceptible to carbapenem-resistant Klebsiella pneumoniae carbapenemase (KPC) infections. However, published experience is limited. OBJECTIVE: To analyze the characteristics and evolution of RT recipients with KPC infection in our hospital. METHODS: We performed a retrospective cohort study of all RT recipients with KPC infection in our hospital from December 1, 2017 (first case), to July 31, 2019. For each RT recipient infected with KPC, 3 controls were selected. RESULTS: During the study period, 8 RT recipients presented KPC infection. Seven were detected in the first year post-RT. The most common site of infection was urine. In 2 cases the germ was isolated in blood. The number of patients with diabetes was significantly higher in the group with KPC infection (P = .023), and urologic interventions were more frequent in those patients (P = .039). No differences were found in the immunosuppressive treatment. A total of 62.5 % of patients required readmission after the KPC infection. One patient died of septicemia by KPC. In all these cases, the clone of KPC isolated was KPC ST512. CONCLUSION: KPC infection is more frequent in the first months after the RT and causes an important number of hospital admissions. It can be cause of death in RT recipients, especially in those with isolation of the germ in blood. Diabetes and urologic interventions were more frequent in this population. The analysis by molecular typing suggests exposure to a common source, highlighting the importance of preventive isolation measures and surveillance for limiting the transmission of this bacteria.
