OBJECTIVE: Donor-derived carbapenem-resistant Klebsiella pneumoniae (CRKP) infection has recently emerged as a critical early complication after renal transplantation. Although CRKP is usually sensitive to tigecycline, monotherapy with this drug is often less than effective. We investigated the efficacy of a combined regimen of tigecycline with high-dose, extended-infusion meropenem in the treatment of donor-derived CRKP infection after kidney transplantation.
METHODS: From Jan. 2016 to Dec. 2017, a total of 12 CRKP isolates were detected from cultures of the organ preservation solution used for soaking the donor kidneys at our institute. Probable or possible donor-derived infection (DDI) was identified in 8 transplant recipients. Clinical data were retrospectively analyzed.
RESULTS: Klebsiella pneumoniae carbapenemase-2 (KPC-2)-producing CRKP was reported to be positive in organ preservation solution cultures at 3.5±0.9 days after transplantation, leading to surgical site (n=3), urinary tract (n=4), and/or bloodstream (n=2) infections in 8 recipients. The drug susceptibility tests showed that CRKP was sensitive to tigecycline, but resistant to meropenem. In 7 patients who received tigecycline combined with high-dose extended-infusion meropenem, DDIs were successfully cured. The length of hospital stay was 31 (18-129) days, and the serum creatinine at discharge was 105.8±16.7 µmol/L. The one remaining patient who received tigecycline combined with intravenous-drip meropenem died of septic shock. A median follow-up of 43 months (33-55) showed no recurrence of new CRKP infection in the 7 surviving recipients.
CONCLUSION: It was suggested that a prompt and appropriate combination therapy using tigecycline with high-dose extended-infusion meropenem is effective in treating donor-derived KPC-2-producing CRKP infection after renal transplantation.
