Inflammation and malnutrition in inflammatory bowel disease

Area of Science:

• Gastroenterology
• Nutrition Science
• Immunology

Background:

• Inflammatory bowel disease (IBD), encompassing Crohn's disease and ulcerative colitis, shows rising global prevalence.
• IBD patients frequently experience malnutrition, including protein-energy malnutrition, sarcopenia, and micronutrient deficiencies, but also overweight and obesity.
• Malnutrition can disrupt gut microbiome homeostasis, leading to dysbiosis and potentially exacerbating inflammation.

Purpose of the Study:

• To review the complex interplay between malnutrition and inflammation in IBD.
• To elucidate pathophysiological mechanisms linking malnutrition and inflammation beyond known deficiencies.
• To discuss the clinical and therapeutic implications of this vicious cycle.

Main Methods:

• Literature review of existing studies on IBD, malnutrition, and inflammation.
• Analysis of proposed mechanisms for the bidirectional relationship.
• Synthesis of clinical and therapeutic insights.

Main Results:

• Malnutrition in IBD presents diverse forms, from undernutrition to obesity.
• Gut microbiome dysbiosis is a key mediator linking malnutrition and inflammation.
• Mechanisms driving the malnutrition-inflammation cycle in IBD are multifaceted.

Conclusions:

• Understanding the vicious cycle between IBD, malnutrition, and inflammation is crucial.
• Targeting nutritional status and gut microbiome may offer novel therapeutic avenues for IBD.
• Further research into these mechanisms can improve patient outcomes.
