Disseminated organ and tissue infection secondary to carbapenem-resistant Klebsiella pneumoniae bloodstream infection for acute lymphoblastic leukemia treated with ceftazidime-avibactam: Two case reports
Abstract
Rationale: Carbapenem-resistant Klebsiella pneumoniae (CRKP) bloodstream infections are a severe complication resulting from granulocyte deficiency following chemotherapy for hematologic malignancies and have a high mortality rate. However, reports of disseminated organ infections secondary to bloodstream infections are rare.
Patient concerns and diagnoses: We report 2 cases of patients with acute lymphoblastic leukemia who both developed CRKP bloodstream infections during the granulocyte deficiency stage following chemotherapy, with 1 case of secondary bacterial liver abscess and 1 case of secondary septic arthritis.
Interventions and outcomes: Based on the results of drug sensitivity testing, both patients were treated with ceftazidime-avibactam, and the infections were rapidly and effectively controlled without significant adverse effects.
Lessons: Ceftazidime-avibactam exhibited satisfactory efficacy and safety in the 2 cases of disseminated organ infection secondary to CRKP bloodstream infection following chemotherapy for acute lymphoblastic leukemia.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
