Treatment of candidal infections with fluconazole in neonates and infants.

Unlabelled: To study the therapy, efficacy and safety of fluconazole in candidal mycoses during neonatal phase and infancy a case review in 53 newborns and infants was performed. The majority of these patients were premature with a median birth weight of 1120 g and born within gestational week 23-38. The median age at the onset of fluconazole treatment was 5 weeks. All patients had underlying diseases and several risk factors, which favored the occurence of a systemic candidal mycosis. Systemic candidiasis was the most frequent diagnosis (75.5%). Fluconazole was administered at a daily dosage of 5-6 mg/kg for a median duration of 21 days. The hepatic, renal and hematologic functions were assessed before, one, two, and three weeks after start of treatment. Yeasts were identified in 37 patients. The most common fungus isolated at baseline was Candida albicans (68%). Clinical cure or improvement was reported in 31 out of 38 patients (81.6%). Mycological cure was achieved in 25 out of 32 newborns and infants. Despite the limited number of patients with outcome data, these preliminary results of a small cohort clearly indicate the effective antifungal therapy with fluconazole in neonates and infants. No serious side effects were observed in fluconazole-treated patients. Two patients with megaureter-megacystis-hydronephrosis syndrome and severe meningoencephalitis showed a mild increase in liver enzymes. -

Conclusion: Fluconazole seems to be an effective therapy for systemic and other forms of candidiasis in infants including very low birth weight infants (VLBWI; <1500 g). These favorable safety and efficacy data are similar to results obtained with fluconazole in older children and adults. These findings, however, must be supported by larger trials. The recommended daily dose is 5 mg/kg body weight. Only in VLBWI the dosage interval within the first two weeks of life should be prolonged up to 3 days and fluconazole serum levels should be monitored.
