ABSTRACT
Fungal infections in neonates are potentially life threatening. The differential diagnosis for neonatal rashes is extensive, with common culprits including both bacteria and fungi. Candida albicans is the predominant fungal pathogen, causing infections that range from superficial disease to severe systemic conditions, including sepsis and meningitis. Neonates, especially those who are preterm, are particularly susceptible because of developmentally immature immune systems and the use of invasive procedures and devices in neonatal intensive care units. Congenital cutaneous candidiasis, acquired in utero or during delivery, can lead to disseminated infection with high mortality rates. Early diagnosis and prompt antifungal treatment are crucial but challenging because of subtle clinical presentations, making accurate identification of the offending organism essential for selecting the appropriate treatment. Candida species account for the majority of neonatal fungal infections, with different species necessitating distinct treatments because of varying susceptibility profiles. Aspergillus, another significant pathogen, poses high mortality risks and can present either cutaneously or systemically. Malassezia, though less common, primarily affects preterm infants with catheter-related fungemia. Other fungal species, including Zygomycetes, Trichosporon, and Cryptococcus, rarely produce neonatal infections but are noteworthy for consideration. Treatment of fungal infection is critical despite the relative paucity of information regarding the clinical pharmacology of many antifungal drugs in neonates. We review the major antifungal agents (e.g., amphotericin B, the echinocandins, the azoles) and provide pharmacologic and dosing information. Finally, preventive strategies, including the use of stringent aseptic techniques and careful clinical monitoring, are essential to mitigate both the incidence and severity of these infections in neonates and infants in the first months of life.
