Annular pustular psoriasis (APP) is a rare form of pustular psoriasis with a chronic recurrent course and good prognosis. We report three cases of APP in children, two of whom were siblings. Review of the medical literature reveals that a disproportionately high percentage of cases of APP occur in children. In some cases topical therapy can clear the condition, although in severe or recalcitrant disease, systemic therapy may be necessary.

To evaluate the long-term efficacy and safety of secukinumab in pediatric patients with generalized pustular psoriasis (GPP). A retrospective study was conducted from July 2021 to July 2024, including 10 children with GPP. Patients were divided into two age groups: children aged 0-3 years received 75 mg of secukinumab, while those aged 3-12 years received 150 mg.

Objectives: The study aims to evaluate the applicability of the D2T psoriatic arthritis (PsA) definition, adapted from rheumatoid arthritis, within a single-center observational cohort of PsA patients treated with b/tsDMARDs. In addition, we aimed to establish a numerical index defining D2T-PsA based on the ratio of observed to expected failed b/tsDMARDs and to develop a predictive model identifying features associated with the D2T condition.
Methods: The study included 267 consecutive adult PsA patients receiving b/tsDMARDs, collecting demographic, clinical, and clinimetric data.

Generalized pustular psoriasis (GPP) is a rare human autoinflammatory disorder with life-threatening systemic effects. Keratinocyte-derived interleukin (IL)-36 signaling has been identified as a key mediator of immune response in the skin of affected individuals. Recognition of various mutations along the IL-36 axis and the downstream nuclear transcription factor κB (NF-κB) signaling have established GPP as genetically, immunologically, and histopathologically distinct and amenable to immunomodulation, which is epitomized by the recent success of IL-36 antagonism.
