BACKGROUND/AIM: Infections are a major cause of morbidity and mortality in children with haematologic malignancies and solid tumors as well as those undergoing hematopoietic stem cell transplantation (HSCT). The purpose of our study was to record the epidemiological characteristics and outcomes of bacteremias, focusing on pathogens, as well as risk factors and mortality rates in patients of a pediatric hematology-oncology unit from Northern Greece.
MATERIALS AND METHODS: A retrospective analysis was conducted, which included all positive blood cultures from pediatric hematology oncology patients aged from 1 to 16 years old admitted to the Pediatric and Adolescent Hematology Oncology Unit of AHEPA University Hospital of Thessaloniki between January 2014 and December 2018. Data were collected from patients' printed and electronic medical records.
RESULTS: 73 episodes of bacteremias were identified (41% male and 32% female with a ratio of 1.28:1; median age 6.5 years; 13.7% solid tumor, 72.6% acute lymphoblastic leukemia, 13.7% acute myeloid leukemia, and 95.8% with an indwelling permanent catheter). 49.3% of the isolates were Gram-positive bacteria and 50.7% Gram-negative, and the ratio of Gram-negative to Grampositive was 1.02. Coagulase-negative staphylococci were most frequent (39.7%), followed by E. coli (17.8%) and Klebsiella pneumoniae (17.8%). Out of all Gram-negatives, 13.5% carbapenemase producers and 8.1% ESBL-producers were found. In relation to Gram-positive, 79.3% were identified as methicillin-resistant CoNS. During the study period, 10.9% of indwelling catheters were removed, and 2.73% of episodes resulted in ICU transfer. The 3-month mortality rate was 8.2%.
CONCLUSION: This study demonstrated an almost equal distribution of Gram-positive and Gramnegative bacteremias in total in this population but with an increase in the isolation of Grampositive bacteria over the last years, which is consistent with other similar studies in this patient group. Knowledge of the local epidemiology and bacterial antimicrobial resistance is important to prevent and timely treat these life-threatening infections in immunocompromised pediatric oncology patients.
