Anorexia nervosa and autoimmune comorbidities: A bidirectional route?

Area of Science:

• Immunology
• Psychiatry
• Gastroenterology

Background:

• Growing evidence links immunological dysfunctions to eating disorders.
• A bidirectional relationship exists between anorexia nervosa (AN) and autoimmune diseases, suggesting shared pathogenesis.
• The immune system's role in AN is an area of increasing scientific interest.

Purpose of the Study:

• To review the multifaceted relationship between the immune system and AN.
• To explore the role of microbiota in immune system disruption and eating disorder development.
• To summarize shared immunological pathways between autoimmune and eating disorders.

Main Methods:

• Literature review of case studies and existing research.
• Analysis of the impact of microbiota on the immune system and gut-brain axis.
• Examination of immunological mechanisms, including T cell tolerance and autoantibodies.

Main Results:

• Numerous cases demonstrate associations between anorexia and autoimmune disorders.
• The microbiota influences the immune system, gut-brain communication, and potentially triggers eating disorders.
• Shared immunological pathways, disrupted T cell tolerance, and autoantibodies are observed in AN.

Conclusions:

• The interplay between the immune system, microbiota, and eating disorders is complex.
• Autoimmunity may play a role in the pathogenesis of eating disorders.
• Further research into these shared pathways is warranted for future therapeutic strategies.
