We identified a case of breakthrough candidemia in a 25-year-old patient receiving micafungin prophylaxis (50 mg/day). Five Candida glabrata isolates were obtained from blood cultures and were classified as multidrug-resistant isolates, since all of them exhibited high MICs for echinocandin and azole drugs. A mutation (S663F) in hot spot 1 of the FKS2 gene was found in all five isolates. This mutation yielded a 1,3-β-D-glucan synthase enzyme with highly reduced sensitivities to echinocandin drugs.

Candida species are the second most frequent fungal pathogen of invasive fungal disease after hematopoietic cell transplantation (HCT) following Aspergillus species. Prolonged severe neutropenia and mucocutaneous barrier impairment resulting from the conditioning regimen or central venous catheter placement are major risk factors for invasive candidiasis in the early phase after HCT. Graft-versus-host disease (GVHD) and corticosteroid use affect the development of invasive candidiasis in the post-engraftment phase after allogeneic HCT.

Breakthrough candidemia (BrC) is a significant problem in immunocompromised patients, particularly those with hematological disorders. To assess the characteristics of BrC in patients with hematologic disease treated with novel antifungal agents, we collected clinical and microbiological information on said patients from 2009 to 2020 in our institution. Forty cases were identified, of which 29 (72.
