    Abstract:
    Bloodstream infection with carbapenem-resistant Klebsiella pneumoniae (CRKP) is a severe and challenging complication in the early post-transplantation period. Pulmonary infection secondary to sepsis caused by CRKP has been reported only rarely in kidney transplant recipients. Here we report an interesting and complicated case in which CRKP was initially isolated in a culture of renal graft preservation solution, yet was not detected in the daily cultures from collection of surgical drainage. Prophylactic tigecycline was terminated at post-transplantation day 10 because of the occurrence of acute pancreatitis. Five days later, the patient suddenly developed a multisite infection with CRKP involving the bloodstream, urinary tract, and lungs, indicating probable transmission from the donor. Fortunately, the infection was controlled quickly and effectively with a combination therapy consisting of ceftazidime-avibactam (CZA) and carbapenem, which was suggested by the results of disc diffusion susceptibility testing. However, the CRKP infection reappeared in the bloodstream and urinary tract soon after the treatment of acute rejection. The combination regimen was continued for another 15 days, and the patient ultimately recovered. During the following 15 months of observation, the patient's renal graft function remained stable, without recurrence of the CRKP infection. In conclusion, the combined use of CZA and carbapenem was safe and produced an optimal therapeutic effect on the severe multisite infection caused by CRKP in a renal transplant recipient, thus providing a reference case for treating such patients.
