AbstractBackgroundTinea capitis is a common contagious fungal infection of the scalp in children. Systemic therapy is required for treatment and to prevent spread.ObjectivesTo assess the effects of systemic anti‐fungal drugs for tinea capitis in children.Search strategyWe searched the Cochrane Skin Group Specialised Register (June 2005), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 2, 2005), MEDLINE (2003 to June 2005), EMBASE ( 2003 to June 2005), LILACS (1982 to July 2005), CINAHL (1982 to July 2005), the ACP journal club (1991 to July 2005) and Healthstar (1975 to July 2005).Selection criteriaRandomised controlled trials (RCTs) that evaluated systemic antifungal therapy in people with normal immunity under the age of 18 who had tinea capitis confirmed by microscopy or growth of dermatophytes in culture or both.Data collection and analysisAt least two authors independently examined each retrieved trial for eligibility and quality.Main resultsWe included 21 studies (1812 participants).Infections involving Trichophyton species: Terbinafine for 4 weeks and griseofulvin for 8 weeks showed similar efficacy in 3 studies involving 382 participants (RR 1.09; 95% CI 0.95 to 1.26). Cure rates following treatment with itraconazole and griseofulvin for 6 weeks were similar in 1 study of 35 children (RR 1.06; 95% CI 0.81 to 1.39). Another study of 100 children did not show any significant difference in cure between itraconazole for 2 weeks compared with griseofulvin for 6 weeks (RR 0.89; 95% CI 0.76 to 1.04). There was no difference between itraconazole and terbinafine for treatment periods lasting 2 to 3 weeks in 2 studies involving 160 children (RR 0.93; 95% CI 0.72 to 1.19). Two studies that included 140 children found similar cure rates between 2 to 4 weeks of fluconazole with 6 weeks of griseofulvin (RR 0.92; 95% CI 0.80 to 1.05).Microsporum infections: There was no significant difference in cure between terbinafine and griseofulvin in children with Microsporum infections in 1 small study of 29 children (RR 0.64; 95% CI 0.19 to 2.20).Authors' conclusionsThe best evidence suggests that newer treatments including terbinafine, itraconazole and fluconazole may be similar to griseofulvin in children with tinea capitis caused by Trichophyton species. Newer treatments may be preferred because shorter treatment durations may improve treatment adherence, although they may be more expensive. There is not enough evidence on the use of systemic treatments in children with Microsporum infections. Not all treatments for tinea capitis are available in paediatric formulations but all have reasonable safety profiles.Plain language summarySystemic antifungal therapy for tinea capitis (also known as ringworm) in children.Tinea capitis is a fungal infection of the scalp caused by two main species called Trichophyton and Microsporum. It is common in children. Systemic therapy is generally required to cure the problem, and several systemic anti‐fungal agents are available. The best evidence suggests that newer treatments such as terbinafine, itraconazole and fluconazole are probably as good as griseofulvin in children with tinea capitis caused by Trichophyton infections. Newer treatments may be preferred because they can be given for shorter treatment durations which may in turn improve adherence to treatment. However, they may be more expensive. There is still not enough evidence on the use of treatments in children with Microsporum infections. Not all treatments for tinea capitis are available in syrup formulations but all appear to be reasonably safe.
