Costa Rican Registry of IL-23 Inhibitors in Psoriatic Disease
Sponsor: Caja Costarricense de Seguro Social
Summary
The goal of this observational registry study is to evaluate the real-world effectiveness and safety of IL-23 inhibitors in patients with psoriatic disease (psoriasis and/or psoriatic arthritis) treated in Costa Rica. The main questions it aims to answer are: * Do IL-23 inhibitors (guselkumab or risankizumab) improve disease severity and quality of life in patients with psoriatic disease in routine clinical practice? * What is the safety profile and treatment persistence of IL-23 inhibitors in this population? * Patients receiving IL-23 inhibitors as part of their usual medical care will be followed longitudinally using standardized clinical measures (e.g., PASI, DLQI, DAPSA/BASDAI) and adverse-event reporting through a national registry.

Interventions
Guselkumab (GUS)
Psoriatic disease, including psoriasis and psoriatic arthritis, is a chronic immune-mediated inflammatory condition with substantial clinical and quality-of-life impact. Several biologic classes are available for moderate-to-severe disease, including TNF-α inhibitors, IL-17 inhibitors, and IL-12/23 inhibitors. IL-23-specific inhibitors (guselkumab and risankizumab) selectively block the p19 subunit of IL-23, providing targeted suppression of the Th17 pathway while preserving IL-12-dependent immune responses. This mechanism distinguishes them from IL-12/23 inhibitors (p40 blockade) and IL-17 inhibitors (downstream cytokine inhibition). IL-23 inhibitors also differ in dosing interval (every 8-12 weeks) and safety profile, with lower candidiasis risk than IL-17 blockade and different infection patterns than TNF-α inhibitors. This national registry specifically evaluates real-world effectiveness, safety, and treatment persistence of IL-23 inhibitors.
