Abstract
Of the various common assayed parameters of iron metabolism, serum ferritin levels are the most discriminatory in distinguishing between non-treated celiac disease and other gastrointestinal disorders in the pediatric age group. Patients on normal diets usually have very low ferritin levels that increase at an average rate of 1 μg/1/month when placed on a gluten-free diet. When the patient returns to a normal diet, however, ferritin levels decrease rapidly at ah average rate of about 4 μg/1/month. There is a relationship between abnormal intestinal changes and low ferritin levels in celiac disease with improvement in both when the patient is on a gluten-free diet. It is suggested that serial blood ferritin evaluations together with the leukocyte migration inhibition factor production assay should eliminate the need for invasive intestinal biopsies for the confirmation and possible follow-up to response to treatment.
