ABSTRACT

Objective:

To explore the early warning value of carbapenem-resistant Klebsiella pneumoniae (CRKP) positivity in liver transplantation recipients with rectal swabs, examine the risk factors of CRKP bloodstream infection and provide the relevant treatments.

Methods:

From June 2018 to December 2019 in Organ Transplantation Research Institute Affiliated Tongji Hospital Tongji Medical College Huazhong University of Science & Technology, 148 cases of liver transplantation recipients with positive CRKP rectal swabbing were recruited. Clinical data were retrospectively analyzed. And the risk factors of CRKP bloodstream infections were examined for intervention and non-intervention groups to observe the effect of interventions of CRKP bloodstream infections.

Results:

Among them, 23 cases (15.5%) were positive for CRKP and 5 cases (21.7%) were infected with CRKP bloodstream. Rectal swab culture was negative in 125 cases and no bloodstream infection occurred. Long-term use of broad-spectrum antimicrobial agents, severe basic diseases (severe hepatitis), postoperative delayed graft liver function recovery, acute renal failure requiring renal replacement therapy (RRT) and postoperative anti-thymocyte globulin (ATG) induction were risk factors. In intervention group, there were 2 cases (11.1%) of 18 patients with positive CRKP in rectal swab culture in late stage. Among 5 CRKP-positive recipients without intervention, 3 cases (60%) developed later CRKP bloodstream infection. The incidence of bloodstream infection was significantly lower in intervention group than that in non-intervention group ( P<0.05).

Conclusions:

Rectal swab culture for liver transplantation recipients provides early warning for CRKP bloodstream infection. Interventions for CRKP positive high-risk recipients with rectal swab culture may reduce the occurrence of CRKP bloodstream infection and lower the risk of CRKP bloodstream infection in liver transplantation recipients.
