Serum ferritin levels in celiac disease

Area of Science:

• Pediatric Gastroenterology
• Iron Metabolism
• Celiac Disease Diagnostics

Background:

• Serum ferritin is a common parameter for iron metabolism.
• Distinguishing celiac disease from other gastrointestinal disorders in children is crucial.
• Intestinal changes and low ferritin levels are linked in celiac disease.

Purpose of the Study:

• To evaluate the discriminatory power of serum ferritin levels in pediatric celiac disease.
• To assess the impact of gluten-free and normal diets on serum ferritin levels.
• To explore non-invasive methods for celiac disease diagnosis and monitoring.

Main Methods:

• Assay of common iron metabolism parameters, focusing on serum ferritin.
• Monitoring ferritin level changes in pediatric patients on gluten-free and normal diets.
• Correlation analysis between intestinal changes, ferritin levels, and dietary interventions.

Main Results:

• Serum ferritin levels are highly discriminatory for non-treated celiac disease in children.
• Gluten-free diet increases ferritin levels (approx. 1 µg/L/month); normal diet decreases them (approx. 4 µg/L/month).
• Improvement in intestinal changes and ferritin levels observed on a gluten-free diet.

Conclusions:

• Serial serum ferritin evaluations can aid in diagnosing pediatric celiac disease.
• Monitoring ferritin levels may help assess treatment response to a gluten-free diet.
• Combining ferritin evaluation with leukocyte migration inhibition factor assay could potentially replace intestinal biopsies.
