Abstract
INTRODUCTION
Febrile neutropenia (FEN) was reported in patients with solid malignancies at a rate of 5-10% and in patients with hematological malignancies at a rate of 20-25%. In our study, we aimed to investigate the effects of mannose-binding lectin 2 (MBL2) (rs1800450) and suppressor of cytokine signaling-1 (SOCS1) (rs33989964) gene variants on patients with FEN.
METHODS
A total of 123 patients who applied to pediatric emergency department between December 2019-12/2020 included in the study. Thirteen patients were excluded from the study due to the inability to obtain DNA. Demographic-clinical features at initial diagnosis and genotype distributions were recorded. The control group consisted of volunteers with the same ethnicity, age and gender, no active infection, and no consanguinity.
RESULTS
CA/CA genotype of SOCS1 was found to be significantly higher in the healthy control group (p = 0.028). AB/BB genotype of MBL2 was significantly higher in FEN patients with a MASCC score of high risk, AA genotype was found to be higher in patients with low risk (p = 0.001). While the rate of microbiologically documented infection (MDI) was significantly lower in patients with the AA genotype of MBL2, it was significantly higher in patients with AA/BB genotypes (p = 0.025). MDI rate in patients with the del/del genotype of SOCS1 was found to be significantly lower than in patients with CA/CA + CA/del genotypes (p = 0.026).
CONCLUSIONS
In this study, it was revealed that low expression-related MBL2 genotypes were riskier for FEN and also, gene variants associated with high SOCS1 transcription were both protective against FEN and increased the rate of culture-negativity.
