Abstract
Purpose
Invasive fungal infection (IFI) causes disability/death in patients with hematologic malignancy (HM) receiving chemotherapy or hematopoietic stem cell transplant (HSCT). There is limited epidemiological data, treatment outcomes, and factors associated with IFI treatment success in Thailand. This study aimed to identify factors associated with IFI treatment success among new HM patients receiving chemotherapy or HSCT, determine IFI incidence among HM patients receiving chemotherapy or HSCT, and the IFI incidence of a breakthrough in patients receiving primary antifungal prophylaxis, and identify antifungal drugs susceptibility.
Patients and Methods
This study reviewed the charts of patients aged ≥ 15 years with newly HM who received chemotherapy or HSCT between January 2016 and June 2021 at King Chulalongkorn Memorial Hospital, Bangkok, Thailand. The 2020 EORTC/MSG criteria were used to diagnose IFI. IFI treatment success factors were evaluated using logistic regression.
Results
Ninety-two patients with 107 episodes of IFI met the inclusion criteria. IFI incidence on proven and probable cases among newly HM patients receiving chemotherapy or HSCT was 7%. Most infections (38.3%) occurred during the induction-phase chemotherapy. Aspergillosis (35.5%) was the commonest IFI, followed by candidiasis (11.2%), Pneumocystis jirovecii pneumonia (8.4%), mucormycosis (3.7%), and others, respectively. The 12-week IFI treatment success rate was 67.3%. It was associated with age < 60 years, absence of coinfection, and the receipt of appropriate empirical therapy on the first day of IFI diagnosis. The incidence of breakthrough IFI from proven and probable cases in patients receiving primary antifungal prophylaxis was 6.1%. Most fungal pathogen isolates were still highly susceptible to antifungal drugs.
Conclusion
The IFI treatment success in patients with HM or HSCT in our study was high. Close monitoring of coinfected patients aged ≥ 60 is recommended. Appropriate antifungal drugs are essential for clinical outcomes.
