Real-world data on the use of secukinumab and acitretin in pediatric generalized pustular psoriasis.

To evaluate the outcomes of secukinumab and acitretin use in children with generalized pustular psoriasis (GPP), we compared the efficacy and adverse events of secukinumab in 20 children and acitretin in 16 children with GPP from January 1, 2019, to January 30, 2022. Among the 20 patients treated with secukinumab, the average time for pustules to fade, temperature to normalize, and C-reactive protein (CRP) to normalize was 3.83, 2.46, and 3.91 days, respectively. All patients recovered (Japanese Dermatological Association severity index score: 0/1) in 3 weeks. The adverse events were abnormal liver enzyme (10%), atopic dermatitis-like lesions (10%), herpes simplex (5%), and neutropenia (10%). For the patients treated with acitretin, the average time for pustules to fade, temperature to normalize, and CRP to normalize was 6, 6.14, and 8.73 days, respectively. The adverse events included mucocutaneous dryness (75%), dyslipidemia (37.5%), and abnormal liver enzyme (25%). These findings demonstrate that secukinumab has more favorable outcomes than acitretin, and secukinumab was well tolerated by the pediatric patients with GPP.
