Approach to anaemia in gastrointestinal disease: A position paper by the ESPGHAN Gastroenterology Committee

Area of Science:

• Pediatric Gastroenterology
• Hematology

Background:

• Anemia is a common complication and presenting symptom of various pediatric gastrointestinal (GI) diseases.
• Pathophysiology is diverse, involving nutritional deficiencies (malabsorption, bleeding), chronic inflammation (IBD), non-inflammatory GI conditions (celiac disease, dysmotility), and medication side effects.

Purpose of the Study:

• To elucidate the multifaceted causes of anemia in pediatric GI diseases.
• To outline diagnostic considerations and therapeutic strategies for managing anemia in this population.

Main Methods:

• Review of pathophysiological mechanisms contributing to anemia in pediatric GI disorders.
• Discussion of diagnostic work-up, considering multiple potential factors.
• Exploration of treatment approaches including supplementation and addressing underlying GI pathology.

Main Results:

• Anemia in pediatric GI disease results from a complex interplay of factors, often requiring extensive investigation.
• Iron and vitamin deficiencies are key, but chronic inflammation and GI integrity also play significant roles.
• Medications used for GI conditions can also contribute to anemia.

Conclusions:

• Effective anemia management in pediatric GI disease necessitates a thorough diagnostic evaluation to identify all contributing factors.
• Treatment involves correcting nutritional deficiencies and, crucially, addressing the underlying gastrointestinal disease, with supplementation routes tailored to anemia severity.
