Update on the management of Candida infections in preterm neonates

Invasive fungal infections in preterm neonates in the neonatal intensive care unit are predominantly caused by Candida spp, and have a high burden of morbidity and mortality. Effective prophylactic strategies have recently become available, but the identification of the best possible strategies to manage high-risk infants is still a priority. Choice and use of appropriate antifungal drugs needs careful assessment of neonatal characteristics, the epidemiology and drug pharmacokinetics. Ideally, antifungal drugs for preterm neonates should target fungal bio-films, prevent or effectively treat end-organ localisations, be active against fluconazole-resistant Candida species, and have reliable safety and tolerability profiles. The paper reviews the state-of-the-art in the area of neonatal fungal infections, and addresses some open questions related to the best possible prophylactic and therapeutic strategies to be implemented in such unique patients.
