Abstract
Tinea capitis caused by Microsporum canis is the most common mycosis of the scalp in preschool and school-aged children in Greece. To compare the efficacy, safety and tolerability of an 8-week course of oral terbinafine at different doses. Patients received oral terbinafine at doses ranging from 3.3 to 12.5 mg/kg/day for 8 weeks, as follows: group A, terbinafine 3.3 to 6.0 to 7.0 mg/kg/day (23 patients); group C, terbinafine > 7.0 to 12.5 mg/kg/day (37 patients). Fungal microscopy and cultures were performed 4 weeks before the start of the treatment, at the end of the treatment (week 8) and at a follow-up visit at week 16. At week 8 mycological cure was achieved in one patient (2.7%) in group A, in 21 patients (91.3%) in group B and in 34 patients (97.1%) in group C. At week 16 mycological cure was achieved in one patient (2.7%) in group A, in 22 patients (95.7%) in group B and in 35 patients (100%) in group C. There was a statistically significant difference (P < 0.0005) between dose level and efficacy of terbinafine at the end of the treatment period and also at the follow-up visit at week 16. Five patients (three in group A and two in group C) discontinued treatment because of adverse events. The administration of terbinafine at a dose of either 6-7 or 7-12.5 mg/kg/day for 8 weeks is safe and effective for the treatment in children of tinea capitis caused by M. canis.
