Oral candidosis: treatment with absorbable and non-absorbable antifungal agents in children.

Oral candidosis in neonates and children is a common infection which occurs often during the first few months after birth, but occasionally also in older children with certain predisposing factors. In neonates, oral candidosis is usually benign, although the symptoms of such an acute infection can be disturbing to both the patient and the parents. In older children developing oral candidosis, specific predisposing factors may be present (e.g. immunodeficiency, chemotherapy, etc.). In such cases, the infection may constitute a source for further dissemination, leading to occasionally fatal Candida sepsis or to widespread chronic mucocutaneous candidosis. Treatment modalities to date include drugs with limited or no absorption from the gastrointestinal tract (e.g. nystatin and miconazole) and agents that are absorbed, combining local effect with systemic therapy (e.g. clotrimazole, ketoconazole, itraconazole and fluconazole). Overall, it appears that treatment of neonatal oral candidosis should be performed with non-absorbable drugs, while the systemically active agents should be used primarily if a risk of dissemination exists or if widespread disease is present. In general, side-effects and toxicity are not major causes of concern with non-absorbed or absorbed antifungals in children with oral candidosis, since treatment is usually of relatively short duration. When the systemically active agents are used in premature infants with sub-optimal liver function, the risk of drug-induced liver toxicity may be increased.
