Nutritional therapy in Crohn's disease

Area of Science:

• Gastroenterology
• Clinical Nutrition

Background:

• Crohn's disease management involves nutritional support for malnutrition.
• The role of nutritional therapy as a primary treatment for Crohn's disease remains debated.
• Corticosteroids are a common treatment, but have side effects.

Purpose of the Study:

• To evaluate the efficacy of enteral nutrition (EN) in Crohn's disease.
• To compare EN remission rates with corticosteroid therapy.
• To explore potential mechanisms and long-term strategies for EN in Crohn's disease.

Main Methods:

• Review of controlled trials comparing enteral nutrition and corticosteroid therapy.
• Analysis of proposed mechanisms of action for EN in Crohn's disease.
• Discussion of strategies for maintaining diet-induced remission.

Main Results:

• Enteral nutrition demonstrates remission rates comparable to corticosteroid therapy in Crohn's disease.
• EN is a preferred treatment for pediatric patients with growth impairment and those with steroid intolerance.
• Mechanisms of EN's efficacy are multifactorial, including bowel rest, reduced antigenic load, and gut microbiome modulation.

Conclusions:

• Enteral nutrition is a valuable therapeutic option for Crohn's disease, particularly in select patient populations.
• Further research into the mechanisms and long-term maintenance strategies for EN is warranted.
• Future nutritional therapies may involve nutrient derivatives targeting intestinal mucosal protection.
