Usage of Antifungal Agents in Pediatric Patients Versus Adults: Knowledge and Gaps

Invasive fungal infections (IFIs) present significant challenges in managing hospitalized and immunocompromised pediatric patients, contributing to high morbidity and mortality. Despite advancements in diagnostics and treatment, outcomes remain suboptimal due to unique clinical epidemiology, lack of pediatric-specific trials, and varied pharmacokinetics. The emergence of new antifungal classes and agents has expanded our options for preventing and treating IFIs in children, enhancing the safety and effectiveness of antifungal therapy. The oral formulations of ibrexafungerp, fosmanogepix and olorofim along with the extended dosing intervals of rezafungin show promising features for effective antifungal treatment in pediatrics. Despite the promising potential of novel antifungal drugs, their performance in heavily immunosuppressed patients remains unstudied. Until then, dedicated antifungal stewardship programs for high-risk patients are essential to optimize therapeutic outcomes, improve patient care, and limit the emergence of resistance.
