Clinical, Epidemiologic, and Therapeutic Characterization of Pediatric Psoriasis in the Costa Rican Social Security System

Overview

The goal of this retrospective observational study is to characterize the clinical features, severity, comorbidities, and treatment patterns of pediatric psoriasis in patients managed in the Costa Rican Social Security System. The main questions it aims to answer are: What are the demographic and clinical characteristics of pediatric psoriasis in Costa Rica? What disease severity profiles, comorbidities, and treatments are observed in routine care? All patients \<18 years with confirmed psoriasis evaluated during the study period will be included. Data will be obtained from electronic health records without intervention or modification of treatment.

Pediatric psoriasis is a chronic immune-mediated inflammatory dermatosis associated with physical, psychosocial, and metabolic comorbidity burden beginning early in life. Epidemiologic and clinical data in Latin American pediatric populations remain limited, particularly in real-world care settings. This study is a retrospective observational characterization of pediatric psoriasis patients managed in the Costa Rican Social Security System. Unlike interventional trials or biologic-specific registries, it analyzes existing clinical records to describe demographic distribution, clinical subtypes, severity (PASI/BSA/DLQI or pediatric indices), comorbidities, and treatment patterns in routine practice. No therapeutic interventions or standardized follow-up are introduced. By capturing real-world pediatric psoriasis presentation and management in Costa Rica, the study provides baseline national evidence distinct from drug-specific or prospective therapeutic studies.
