Abstrakt: Purpose: The efficacy of prophylactic antimicrobial treatment renders challenges in patients with leukemias receiving chemotherapy. The study aimed to compare differences in C-reactive protein (CRP) and procalcitonin (PCT) at presentation and the immediate outcome measures of post-chemotherapy NF between patients with and without antimicrobial prophylaxis.
Methods: A 5-year observational study included 282 NF episodes in 133 leukemia patients requiring hospital care from January 2014 to May 2019. We collected demographic characteristics, laboratory data of blood cell counts and inflammatory biomarkers, and immediate outcome measures of NF, including microbiologically diagnosed infections, presence of predominant pathogens, required modification of antibiotics during NF, adverse medical complications, total fever duration, and deaths. We evaluated data between patients with and without prophylaxis.
Results: Of patients, 77.3%, 68.4%, and 20.6% had antibiotic prophylaxis, antifungal prophylaxis, and no prophylaxis, respectively. There were totally 15 deaths-13 with antibiotic prophylaxis and 10 with antifungal prophylaxis. CRP, PCT, and immediate outcome measures of NF did not show significant differences between those with and without antimicrobial prophylaxis. Although between-group differences showed no statistical significance, higher median fever duration, CRP and PTC values, and higher proportions of NF requiring modification of antibiotics were found more frequently in those with antimicrobial prophylaxis than in those without.
Conclusion: The benefits of using antimicrobial prophylaxis were less supported. Enhancing diagnostic laboratory and medical complication surveillance and periodic evaluation of institutional data during post-chemotherapy neutropenia and NF in relation to antimicrobial prophylaxis is promising in providing insights to redefine the risk-benefit accounts of using prophylaxis.
