Background: The emergence of COVID-19 has led to a significant public health crisis, and an increase in fungal infections, including candidemia. Candida species are frequently found in intensive care units (ICUs), and it is a common cause of death in many patients. The isolates were identified using polymerase chain reaction-restriction. In this study, We investigated the factors linked to Candida infections in COVID-19 burn patients in the ICU and assessed the antifungal susceptibility of the isolates in vitro.
Methods: Out of 335 burn patients admitted to the ICU, fifty-six with concurrent COVID-19 were included in this study. A total of 133 yeast isolates were obtained from burn wounds, 29 from blood cultures, and 36 from urine cultures. The isolates were identified using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis.
Results: Out of fifty-six patients, twenty-nine had infections and forty-eight had colonization, with Candida parapsilosis being the most common species. Twenty-one patients died during their ICU stay, with mortality rates of 43.8% among colonized patients and 69.0% among infected patients. Fluconazole and itraconazole exhibited the highest minimum inhibitory concentrations, while luliconazole and amphotericin B were identified as the most effective antifungal agents.
Conclusion: Our findings indicate that colonization may act as an important prognostic factor prior to the onset of candidemia. In addition, prolonged hospitalization, catheter use, and concurrent COVID-19 infection were identified as key risk factors for candidemia in this patient group. Notably, the rising drug resistance in non-albicans Candida species is a major public health concern.
