As data on pediatric invasive candidiasis (IC) and the antifungal susceptibility pattern of associated isolates are scarce in Iran, this study aimed to determine species distribution and antifungal susceptibility profile of Candida species isolated from pediatric patients with suspected or documented IC. A total of 235 yeast strains recovered from normally sterile body fluids of patients admitted at the intensive care units of Children's Medical Centre, Tehran, Iran, were identified using CHROMagar Candida, molecular methods (ITS PCR-RFLP and sequencing), and MALDI-TOF. Susceptibility to amphotericin B, fluconazole, voriconazole, micafungin, and anidulafungin was determined according to the European on Antimicrobial Susceptibility testing reference microdilution method (EUCAST E.Def 7.3.1). Candida albicans (53.6%), C. parapsilosis (24.7%), and C. tropicalis (8.5%) were the most common species, followed by C. lusitaniae (4.3%), C. glabrata (3.0%), C. guilliermondii and C. orthopsilosis (each 1.7%), C. kefyr (1.3%), C. dubliniensis (0.8%), and C. intermedia (0.4%). Amphotericin B MICs were ≤1 mg/l for all Candida isolates. C. albicans isolates were susceptible to all five antifungal agents. All C. parapsilosis isolates categorised as intermediate to micafungin and anidulafungin, except two isolates that had the MICs >2 mg/l for micafungin. MIC50, MIC90, and MIC range for fluconazole were 0.25 mg/l, 1 mg/l, and 0.125 - ≥32 mg/l, respectively. Fluconazole and voriconazole showed 100% activity against the most prevalent Candida species. The low resistance rate, favorable safety profile and low cost of fluconazole make it a reasonable choice for treatment of candidemia/invasive candidemia in Iran.
