Therapeutic challenges in managing pediatric psoriasis

BACKGROUND: Each year, 20,000 patients aged <10 years are diagnosed with psoriasis. Pediatric-onset psoriasis has many similarities to adult-onset disease, and previous studies suggest that the incidence might be increasing in both populations. OBJECTIVE: The challenges that arise when treating patients with psoriasis, especially those age <12 years, are summarized, as well as the limited available treatment options for treating pediatric patients with psoriasis and the evidence supporting each of them. METHODS: Recently published guidelines by the American Academy of Dermatology and the National Psoriasis Foundations, as well as guidelines published by the German Society of Dermatology, provide considerable insight in managing patients who have this condition. The latest studies on pediatric psoriasis treatment were reviewed, including recent and current clinical trials with U.S. Food and Drug Administration approved and nonapproved medications, case reports, case series, and reviews. The authors also reviewed American and European guidelines, as well as recommendations from expert panels. RESULTS: Currently, only six medications are approved by the U.S. Food and Drug Administration for the treatment of pediatric psoriasis: three biologics and three topical. Many off-label topical treatments have been used in pediatric psoriasis, with variable effectiveness and safety profiles. Data from adult clinical trials, as well as case reports and series from pediatric patients, suggest that other biologic medications are effective for pediatric psoriasis. CONCLUSION: Many questions remain unanswered, leaving clinicians facing multiple challenges when encountering pediatric patients with psoriasis. This summation will help provide an overview of current on- and off-label medications for pediatric psoriasis. Pediatric clinical trials should be implemented to obtain data that can result in expanding the therapeutic spectrum for this population, parallel to their adult counterparts.
