Psoriatic disease, including psoriasis and psoriatic arthritis, is a chronic inflammatory condition with substantial clinical and functional impact. Although IL-23 inhibitors such as guselkumab and risankizumab have shown high efficacy and favorable safety in international trials, real-world evidence in Latin America-and particularly Costa Rica-is limited. Differences in comorbidities, population genetics, access to therapy, and health-system factors may influence treatment response and safety outcomes.
This national observational registry is designed to generate standardized real-world data on patients with psoriatic disease treated with IL-23 inhibitors within the Costa Rican public health system. The registry will collect demographic and clinical characteristics, dermatologic and rheumatologic disease activity scores, treatment patterns, persistence, and adverse events over time. The resulting evidence will support clinical decision-making, optimize therapeutic strategies, and inform national health policy regarding biologic therapies for psoriatic disease.
