The association of isoconazole–diflucortolone in the treatment of pediatric tinea corporis

Background: Tinea corporis is a common mycotic infection in children. Staphylococcus aureus superinfections may be observed in atopic children with tinea corporis suffering from severe pruritus and consequent scratching.Objective: From 2006 to 2011, we observed 288 children with mycologically proven tinea corporis. In 39 of them (13.5%) tinea corporis was superinfected by S. aureus: all these children were affected by atopic dermatitis. We interpreted these bacterial superinfections as the clinical result of scratching due to pruritus.Methods: In 2012, we decided to treat all children with a single lesion of tinea corporis with a combination of 1% isoconazole nitrate and 0.1% diflucortolone valerate cream (one application/day for 5–7 days), followed by a treatment with isoconazole or clotrimazole or ciclopirox cream (two applications/day for two weeks).Results: From 2012 to 2014, we observed 108 children with tinea corporis confirmed by mycological examinations. Clinical and mycological recovery was observed in 93 of them (86.1%). Only four of these children (3.7%) developed S. aureus superinfections.Conclusions: Our study in atopic children with tinea corporis superinfected by S. aureus confirms that a topical therapy with the association isoconazole–diflucortolone is useful and safe.
