From the Guidelines
The recommended treatment approach for pediatric patients with refractory acne is oral isotretinoin at a dosage of 0.5-1 mg/kg/day for a total cumulative dose of 120-150 mg/kg over a 4-6 month course, as strongly recommended by the guidelines of care for the management of acne vulgaris 1.
Treatment Approach
The treatment of pediatric patients with refractory acne should prioritize oral isotretinoin due to its effectiveness in reducing sebum production, normalizing follicular keratinization, and decreasing Cutibacterium acnes colonization, making it particularly effective for severe nodular acne that hasn't responded to conventional therapies.
Key Considerations
- Before initiating isotretinoin, patients should undergo baseline laboratory tests including lipid profiles and liver function tests, with monthly monitoring throughout treatment 1.
- For female patients of reproductive age, two forms of contraception are mandatory due to isotretinoin's teratogenic effects, along with monthly pregnancy tests.
- Alternative approaches for refractory acne include combination therapy with oral antibiotics (such as doxycycline 50-100 mg twice daily or minocycline 50-100 mg twice daily) for 3-4 months alongside topical retinoids (adapalene 0.1% or tretinoin 0.025-0.05% applied nightly) and benzoyl peroxide (2.5-5% applied once or twice daily) 1.
- For female patients, hormonal therapy with combined oral contraceptives or spironolactone (50-200 mg daily) may be effective.
Monitoring and Side Effects
Close monitoring for side effects including dry skin, cheilitis, mood changes, and potential hepatotoxicity is essential throughout treatment 1.
Guidelines and Recommendations
The guidelines of care for the management of acne vulgaris provide strong recommendations for oral isotretinoin for severe acne, acne causing psychosocial burden or scarring, or acne failing standard treatment with oral or topical therapy 1.
From the FDA Drug Label
The use of isotretinoin for the treatment of severe recalcitrant nodular acne in pediatric patients ages 12 to 17 years should be given careful consideration, especially for those patients where a known metabolic or structural bone disease exists Use of isotretinoin in this age group for severe recalcitrant nodular acne is supported by evidence from a clinical study comparing 103 pediatric patients (13 to 17 years) to 197 adult patients (≥18 years) Results from this study demonstrated that isotretinoin, at a dose of 1 mg/kg/day given in two divided doses, was equally effective in treating severe recalcitrant nodular acne in both pediatric and adult patients
The recommended treatment approach for pediatric patients with refractory acne is to consider the use of isotretinoin at a dose of 1 mg/kg/day given in two divided doses, especially for those with severe recalcitrant nodular acne. However, careful consideration should be given to patients with known metabolic or structural bone disease. Key points to consider include:
- Age: Isotretinoin can be used in pediatric patients ages 12 to 17 years.
- Dose: The recommended dose is 1 mg/kg/day given in two divided doses.
- Efficacy: Isotretinoin is equally effective in treating severe recalcitrant nodular acne in both pediatric and adult patients.
- Safety: Careful consideration should be given to patients with known metabolic or structural bone disease due to potential adverse effects on bone mineral density 2.
From the Research
Treatment Approach for Pediatric Refractory Acne
The treatment of pediatric refractory acne requires a comprehensive approach, considering the age and pubertal status of the patient.
- For mild to moderate acne, topical retinoids, benzoyl peroxide, and topical antibiotics can be effective 3, 4.
- In cases of moderate to severe inflammatory acne, oral antibiotics such as doxycycline or tetracycline can be used, ideally in combination with topical benzoyl peroxide or a topical retinoid to minimize the risk of antibiotic resistance 5, 6.
- Hormonal therapy, including oral contraceptives, may be considered for female patients with acne, particularly those with hormonal imbalances 6, 4.
- Isotretinoin, an oral retinoid, is reserved for the most severe or refractory cases of acne, due to its potential side effects and teratogenicity 6, 3, 4.
Considerations for Pediatric Patients
When treating pediatric patients with refractory acne, it is essential to consider their age, pubertal status, and potential side effects of medications.
- The American Acne and Rosacea Society has developed evidence-based guidelines for the management of pediatric acne, including recommendations for classification, diagnosis, evaluation, and treatment 7.
- Treatment algorithms and recommendations are presented for different age groups, including adolescent, preadolescent, infantile, and neonatal acne 7.
- Psychosocial effects of acne, adherence to treatment regimens, and the role of diet in acne management are also important considerations when treating pediatric patients 7.
