Aminosalicylate use Increases Corticosteroid Exposure and Decreases Biologic Durability in Pediatric Crohn's Disease.

This study suggests that using 5‑ASA drugs early in children with Crohn’s disease was common but linked to more steroid use, delayed biologic treatment, and lower biologic durability — outcomes that matter for long‑term...
