Fusariosis in burn patients: A systematic review of case reports

Burns can cause skin damage, facilitating the entry of fungi and other microorganisms into the body, leading to infections. Fusarium is a fungus capable of infecting individuals with burn injuries. Diagnosing and treating Fusarium infections in burn patients can be challenging due to the manifestation of nonspecific symptoms. This study aims to investigate case reports and case series from published literature describing Fusarium infection in burned patients, in order to assess treatment regimens, clinical outcomes, and make recommendations for future management. We conducted searches on Web of Science, PubMed, ScienceDirect, and Medline for all case reports and case series containing keywords 'Burn', 'Burns', 'Burned', 'Fusarium', or 'Fusariosis' in the title or abstract. All burn patients who developed Fusarium fungal infections between January 1974 and March 2023 were included in the study. Demographic and clinical data were analyzed retrospectivity. The final analysis incorporates 24 case reports encompassing a total of 87 burn patients with Fusarium infection. Patient ages ranged from one to 85 years, with the majority being male (53%). The median percentage of burn surface area was 78%, and the skin in the face, upper limbs, and lower limbs were the most commonly infected sites. Fungal infections appeared around 10 days after the burn injury on average. The majority of the patients were identified through culture or histopathology. The Fusarium dimerum species complex, which was found in nine patients, was the most frequently identified Fusarium species complex. Amphotericin B was the most preferred treatment drug, followed by voriconazole, and 62% of patients underwent debridement. In our study, 23 patients (37%) died from fungal infections. Implementing early and effective treatment protocols targeting Fusarium spp. in burn treatment units can significantly reduce mortality rates. It is critical to enhance the understanding of fusariosis epidemiology and emphasize the importance of maintaining a high clinical suspicion for this condition in burn patients.
