Successful treatment of hypervirulent Klebsiella pneumoniae bacteremia with combination carbapenem and rifampicin

Abstract

Hypervirulent Klebsiella pneumoniae (hvKP) with a high mucus phenotype, can cause liver abscess and extrahepatic invasive infection. The morbidity of hvKP infections has increased recently. Here we describe a case report of septicemia caused by hvKP due to the term septic arthritis of right knee joint in a 29-year-old male. The patient was persistent fever with a peak temperature at 40.6 °C. However, based on the drug sensitivity, the treatment failed frequently. The patient did not improve clinically on susceptible monotherapy antimicrobial. Combination therapy with meropenem and rifampicin (RFP) lead to clinical improvement and discharge.
