小児サプロチャエテ感染症：症例報告からの洞察

Saprochaete species are emerging fungal pathogens, particularly affecting immunocompromised individuals, with clinical manifestations ranging from superficial to invasive infections. We present three cases of pediatric Saprochaete spp. infections, detailing clinical presentation, diagnostic workup, and treatment strategies. Two patients with acute myeloid leukemia developed bloodstream infections with Saprochaete clavata; both required prolonged antifungal therapy due to deep organ involvement, and one experienced relapse after treatment discontinuation. The third case involved a patient with cystic fibrosis, in whom Saprochaete capitata was isolated from sputum; she improved with antifungal therapy and had no relapse. Saprochaete spp. infections in pediatric populations present diagnostic and therapeutic challenges. Further research is needed to optimize management strategies and improve patient outcomes.
