Clinical characteristics and outcomes of Fusarium infections in adult patients after hematopoietic stem cell transplantation: A meta-summary of case reports

Abstract

Fusarium infections have increased, particularly among patients with hematological malignancies and in those receiving hematopoietic stem cell transplantation (HSCT). This meta-summary summarizes the clinical characteristics, treatment, and outcomes of Fusarium infections in HSCT recipients. The PubMed, ScienceDirect, and Ovid SP databases were searched from inception to January 2024 to identify relevant case reports. A total of 31 patients diagnosed with Fusarium infections after HSCT were included. The most common infection sites were the skin and soft tissues (74.2%), blood (54.8%), and lungs (41.9%). Fusarium species complex was identified in 67.7% of the patients, and the most common species was Fusarium solani (51.6%). Of the included patients, 58.1% received antifungal monotherapy, whereas 41.9% received antifungal combination therapy. The overall mortality rate was 74.2%. Cutaneous infection was associated with a low mortality rate. The median time to mortality was 28 days. Fusarium infections commonly present as disseminated infections in HSCT recipients.
