Antifungal prophylaxis for the prevention of neonatal candidiasis?

Background: Randomized controlled trials suggest that prophylactic administration of antifungal agents reduce the rate of colonization and invasive Candida infection in a subgroup of high-risk very low birth weight (VLBW) neonates. The extent of antifungal prophylaxis use in the United Kingdom and Ireland is unknown. Methods: A postal questionnaire was administered to neonatologists practicing in the United Kingdom and Ireland caring for VLBW infants. Information was requested on the prophylactic agents used, dosing schedules and duration of therapy. The rationale for reported practices was also ascertained. Results: The response rate was 55% (125/228). Antifungal prophylaxis use was reported by 66 (53%) respondents. First-line agents utilized included oral nystatin (53%) and intravenous fluconazole (41%). The most frequent indications for antifungal prophylaxis included antibiotic administration in 45 (68%) and decreased birth weight in 33 (50%) respondents. The majority of respondents who did not use antifungal prophylaxis felt that the perceived rate of invasive fungal disease within their unit was not high enough to justify its use. Conclusions: A small majority of clinicians caring for VLBW neonates routinely use antifungal prophylaxis. This reflects the wide variation in the incidence of invasive disease, lack of guidelines supporting a role for prophylaxis and concerns related to emergence of resistant strains.
