Safety and efficacy of terbinafine in a pediatric Iranian cohort of patients with Tinea capitis

AbstractBackground and objectivesTinea capitis is a common infection of the scalp and hair shaft caused by dermatophyte fungi that mainly affects prepubescent children. Systemic therapy is required for treatment and to prevent spread. The aim of present study was to assess the effect of terbinafine for Tinea capitis treatment in children.MethodsThirty Iranian pediatric patients with a clinical diagnosis of Tinea capitis were enrolled in the study. The Study was conducted in a general and referral teaching hospital (Imam Medical Centre – Tehran, Iran) from 2006 to 2007. Eligible patients with less than 20kg of body weight were given 62.5mg terbinafine, and for patients between 20 and 40kg the dose was 125mg, on the first visit. All patients had the second clinical visit and second samples for microscopic study were taken. For each patient, direct mycology test (KOH test) and mycological culture were carried out before the study was started and after second, fourth, fifth, sixth and eighth weeks. Probable drug’s adverse effects were also recorded.ResultsBased on the results of mycological culture of patients’ lesions, Microsporum canis and Trichophyton sheonlini were considered as major causes of Tinea capitis in these children. Out of 30 study patients, KOH test of 93% in the 5th week and 100% in the 6th week was negative. All patients healed completely from signs of infection, after six weeks. Also, no severe side effects were seen in any patients.ConclusionAccording to the results of this study, the use of terbinafine is an effective therapy in Iranian cases of Tinea capitis in children without severe side effects
