To review the use of antifungal chemoprophylaxis to prevent neonatal invasive fungal infections (IFI) in very low birthweight infants (VLBW <1500 g).

Systematic review of randomised controlled trials.

Nine trials were identified (2029 infants), with six comparing fluconazole with placebo/no treatment (840 infants), three comparing nystatin with placebo/no treatment (1200 infants) and two comparing fluconazole and nystatin (257 infants). Prophylactic fluconazole reduced the incidence of IFI in VLBW infants <1500 g to 5.1% compared with 16.0% in infants receiving placebo, relative risk (RR) = 0.36 (95% confidence interval 0.15-0.89). The mortality was 10.9% and 16.7%, respectively (RR 0.76, 0.54-1.08). Oral nystatin reduced the incidence of IFI in VLBW infants to 5.3% compared with 28.0% in infants receiving placebo (RR 0.16, 0.11-0.23). Mortality was 7.5% with nystatin and 10.9% with placebo (RR 0.86, 0.59-1.26). The incidence of IFI in studies comparing fluconazole and nystatin was 3.6% and 8.0%, respectively (RR 0.54, 0.19-1.56), and mortality was not significantly different: 4.6% versus 9.8% (RR 0.43, 0-4.31)

Prophylactic fluconazole and oral nystatin are both highly effective in preventing IFI in VLBW infants. Both agents are safe without significant toxicities. Antifungal prophylaxis should therefore be used in all VLBW infants. Given the paucity of data comparing fluconazole with nystatin, the choice of antifungal agent should be influenced by the incidence of IFI, local epidemiology and relative cost.

    ABSTRACT: Preterm infants, born with immature innate immunity, are less likely to develop anaphylaxis. Fluconazole prophylaxis during the first six weeks of life decreases invasive candidiasis in very low birth weight infants. Adverse effects of fluconazole are very rare. In this study, we report a newborn (a male, 26 weeks gestation and 900 g birth weight) who developed anaphylaxis after fluconazole administration. Hypotension and erythematous rash were present. We believe this to be the first anaphylaxis case in newborns caused by fluconazole in literature. Clinicians should be aware of the possibility of this potentially fatal adverse effect occurring with intravenous fluconazole.

    ABSTRACT: Background Premature infants are at high risk of developing invasive candidal infections (ICI). We investigated maternal and perinatal risk factors for ICI that may help in defining at-risk infants, allowing more targeted antifungal prophylaxis to prevent morbidity and mortality.

    ABSTRACT: Invasive fungal infections due to Candida are the third most common late-onset infection in infants born with birth weight <1500 g. Invasive candidiasis in infants born with birth weight <1000 g is associated with a 30% mortality and with neurodevelopmental impairment in more than half the survivors. A high degree of suspicion and a thorough multisystem evaluation is necessary for diagnosis of invasive fungal infections and to detect complications or sequalae. Amphotericin B deoxycholate is the mainstay in the treatment of invasive fungal infections in newborns. Early initiation of enteral feeds with human milk, decreasing dependence on catheters and avoidance of antacids, steroids and broad-spectrum antibiotics are the recommended preventive measures. Fluconazole prophylaxis should be targeted towards neonates born with <1000 g in neonatal units where baseline rates of invasive candidiasis are more than 5%.
