What is the ideal management for a 1-year-old with tinea capitis?

From the Guidelines

The ideal management for a 1-year-old with tinea capitis is oral antifungal therapy with griseofulvin as the first-line treatment, at a dose of 15-20 mg/kg/day for 6-8 weeks, as recommended by the British Association of Dermatologists' guidelines 1.

Key Considerations

• The choice of systemic therapy should be directed by the causative dermatophyte and/or local epidemiology 1.
• Topical therapy alone is not recommended for the treatment of tinea capitis, and oral therapy is generally indicated to achieve both clinical and mycological cure 1.
• Terbinafine is an alternative option, particularly for Trichophyton species, at a dose of 625 mg per day for 2-4 weeks for children under 20 kg 1.

Additional Measures

• Children receiving appropriate therapy should be allowed to attend school or nursery 1.
• Index cases due to T. tonsurans warrant screening of all family members and close contacts and treatment for those positive cases 1.
• Antifungal shampoo containing 2% ketoconazole or 1% selenium sulfide can be used 2-3 times weekly to reduce spore shedding and prevent transmission.

Treatment Monitoring

• The end point of treatment is mycological rather than clinical cure, and repeat mycology sampling is recommended until mycological clearance is achieved 1.
• Treatment failure should be addressed by considering lack of compliance, suboptimal absorption of drug, relative insensitivity of the organism, and reinfection, and adjusting the treatment regimen accordingly 1.

From the FDA Drug Label

DOSAGE AND ADMINISTRATION ... Pediatric patients (older than 2 years): A dosage of 10 mg/kg daily is usually adequate Representative treatment periods are tinea capitis, 4 to 6 weeks;

The ideal management for a 1-year-old with tinea capitis is not directly stated in the FDA drug label because the patient is younger than 2 years, and the label only provides dosage information for pediatric patients older than 2 years. Key points:

• The label does not provide information for patients under 2 years.
• Treatment periods for tinea capitis are 4 to 6 weeks, but this information is not directly applicable to a 1-year-old patient. 2

From the Research

Ideal Management for Tinea Capitis in a 1-Year-Old

The ideal management for a 1-year-old with tinea capitis involves a combination of oral antifungal medications and adjuvant topical therapy.

• The standard of care for the treatment of tinea capitis is oral griseofulvin, which remains the only medication approved by the US FDA for this condition 3, 4.
• Other oral antifungal agents, such as terbinafine, itraconazole, and fluconazole, appear to be effective, safe, and have the advantage of a shorter treatment duration 3, 5, 4, 6.
• Griseofulvin is still the treatment of choice for cases caused by Microsporum species, while terbinafine, itraconazole, and fluconazole may be used for cases caused by Trichophyton species 6.
• Adjuvant topical therapy with 2% ketoconazole or 1% selenium sulfide shampoos may be recommended to reduce surface colony counts of dermatophytes 3, 4.

Treatment Options and Duration

• Griseofulvin treatment typically lasts 6 to 8 weeks 7.
• Terbinafine treatment requires 6 weeks 7.
• Itraconazole and fluconazole may have shorter treatment durations, but their use is not FDA-approved for tinea capitis 3, 5, 6.
• The choice of treatment should be based on the causative fungal organism, the severity of the infection, and the patient's age and medical history 6.

Important Considerations

• Tinea capitis always requires systemic treatment, as topical antifungal agents do not penetrate the hair follicle 6.
• Regular epidemiological surveillance of causative fungal organisms in the community and their antifungal susceptibility is essential for effective management 3.
• The treatment of tinea capitis should be guided by evidence-based practice guidelines, such as those from the European Society for Pediatric Dermatology 6.
