. So far there has been no clear protocol on the treatment of bacterial infections in hematopoietic cancer patients undergoing polychemotherapy (PCT) and hematopoietic stem cell transplantation (HSCT). Guidelines available from antibiotic therapy panels such as EMBT, NCCN, ECIL, Sepsis-3 often fail to cover the entire spectrum of clinical risk factors of severe complications caused specifically by multiresistant Klebsiella pneumoniae. The aim of the study — is to showcase the clinical experience of demonstration of the experience of the Research Institute of Pediatric Oncology and Hematology at N.N. Blokhin Russian Cancer Research Center with respect to adjusting antibacterial therapy for the spectrum of microorganisms found in the patient before the onset of antitumor therapy, and for the multiresistant microorganism findings in patients with blood cancers and febrile neutropenia (FN) undergoing PCT and HSCT. Materials and methods . The study involved five patients undergoing either PCT or HSCT for hematopoietic cancers at Research Institute of Pediatric Oncology and Hematology in October 2019 — October 2020, multiresistant Klebsiella pneumonia colonies found in each case. Results. Five patients with hematopoietic cancers and induced bone marrow aplasia were found to have multiresistant Klebsiella pneumoniae colonies on top of post-PCT/HSCT immunosuppression. Given high risk of death, these patients need early antibacterial therapy with reserve antibiotics outside standard empirical antibacterial treatment protocols should they develop FN. The Center's practices have shown that baseline protocols are often inadequate to the severity of these patients' conditions in a certain timeframe. Conclusions . To sum up the Center's limited experience, the finding is that additional research is required into the factors of risk of severe multiresistant Klebsiella pneumoniae infections in patients undergoing PCT and HSCT; algorithms must be developed for the treatment of patients in such a critical condition.
