Perspectives on the Use of Echinocandins in the Neonatal Intensive Care Unit.

The neonatal intensive care unit (NICU) population, especially low birth weight and critically ill neonates, is at risk of invasive Candida infections, which are associated with high mortality rates and unfavorable long-term outcomes. The timely initiation of an appropriate antifungal treatment has been demonstrated to enhance the prognosis. Factors that should be considered in the choice of an antifungal agent include the causative Candida strain, the presence and location of deep tissue infection, any previous use of antifungal prophylaxis, and the presence of implanted devices. Amphotericin B and fluconazole, the first-line drugs for neonatal candidiasis, are not always suitable due to several limitations in terms of efficacy and adverse effects. Therefore, alternative antifungals have been studied and used in neonates when conventional antifungals are ineffective or contraindicated. This narrative review aims to provide an overview of the current literature regarding the use of echinocandins in the neonatal population. The three echinocandins, micafungin, caspofungin, and anidulafungin, share characteristics that make them useful for the treatment of neonatal candidiasis, including activity against a wide range of Candida strains and Candida biofilms and a favorable safety profile.
