Research Progress on Exclusive Enteral Nutrition Combined with Biologics in the Treatment of Adult Crohn’s Disease

Combined therapy with Exclusive Enteral Nutrition (EEN) and biologics shows promise in managing complex Crohn's Disease (CD), with studies reporting improved remission rates. This clinical benefit may be attributed to a synergistic effect supported by a plausible biological basis. However, these favorable outcomes are based on low-certainty evidence from limited clinical studies. Robust randomized controlled trials are needed to establish the effectiveness, safety, and best use of this combination approach.
