The Relationship Between Nutritional Status, Micronutrient Deficiency, and Disease Activity in IBD Patients: A...

Area of Science:

• Gastroenterology
• Clinical Nutrition
• Immunology

Background:

• Inflammatory bowel diseases (IBD) are chronic gastrointestinal disorders characterized by inflammation.
• The inflammatory state leads to undernutrition and impaired nutrient absorption due to mucosal damage.
• Understanding the link between nutritional status and disease activity is crucial for patient management.

Purpose of the Study:

• To evaluate the relationship between nutritional status, including micronutrient deficiencies, and disease activity in IBD patients.
• To assess the clinical and laboratory markers of disease activity in relation to nutritional parameters.
• To identify potential nutritional indicators for active IBD.

Main Methods:

• Cross-sectional study conducted across three Italian centers.
• Collected baseline data, clinical disease activity, and laboratory results.
• Assessed micronutrients (iron, ferritin, vitamin B12, vitamin D, folate), hemoglobin, and albumin.
• Employed Pearson correlation and receiver operating characteristics (ROC) analyses.

Main Results:

• 110 IBD patients (40 Crohn's Disease, 70 Ulcerative Colitis) were analyzed.
• Hemoglobin, iron, ferritin, and vitamin D levels differed significantly between active and inactive disease groups (p < 0.007).
• Iron and vitamin D showed the highest accuracy in ROC analysis (AUC 0.76 and 0.68, respectively), though suboptimal.

Conclusions:

• Hemoglobin, iron, ferritin, and vitamin D are associated with IBD disease activity.
• These markers demonstrate suboptimal accuracy in differentiating active from inactive disease.
• Folic acid, vitamin B12, and albumin showed poor correlation with disease activity status.
