The Crosstalk between Vitamin D and Pediatric Digestive Disorders

Area of Science:

• Endocrinology
• Gastroenterology
• Immunology

Background:

• Vitamin D, a steroid hormone, is vital for calcium homeostasis and bone health.
• Emerging research highlights its significant roles in gastrointestinal functions, including immune modulation and gut barrier integrity.
• Sources include sunlight, diet, and supplements, with Vitamin D3 being the most potent form.

Purpose of the Study:

• To review the multifaceted roles of vitamin D in gastrointestinal health and disease.
• To explore the association between vitamin D levels and various gastrointestinal conditions.
• To emphasize the importance of monitoring vitamin D status in patients with digestive disorders.

Main Methods:

• Literature review of recent studies on vitamin D and gastrointestinal health.
• Analysis of the impact of vitamin D on H. pylori infection, celiac disease, cystic fibrosis, and inflammatory bowel disease.
• Synthesis of findings regarding vitamin D's role in gut barrier function and microbiota modulation.

Main Results:

• Vitamin D supplementation may improve H. pylori eradication rates.
• Vitamin D deficiency is linked to celiac disease pathophysiology and severity.
• Adequate vitamin D levels are associated with improved lung function in cystic fibrosis and remission in inflammatory bowel disease.
• Vitamin D's role in food allergies, diarrhea, and constipation requires further investigation.

Conclusions:

• Vitamin D is integral to maintaining gastrointestinal homeostasis.
• Monitoring and ensuring sufficient vitamin D levels are crucial for managing various digestive diseases.
• Further research is needed to fully elucidate vitamin D's complex impact on the gut.
