Abstract Anemia in celiac disease (CD) has been attributed to nutritional deficiencies; however, the clinical manifestations of CD have changed with nongastrointestinal presentations predominating. We collected hematologic parameters from a cohort of patients seen at a tertiary care center for CD to assess the characteristics of anemia in this population. Hematological parameters measured 1995 was analyzed. Ferritin levels were compared with population controls (NHANES III). Iron deficiency was common, occurring in 33\% of men and 19\% of women (P < 0.001). Folate deficiency was seen in approximately 12\% of the total sample and B12 deficiency in approximately 5\%. Anemia was present in approximately 20\% of the cohort. Among the anemic patients, ferritin was less than the 10th percentile in 45\%, between the 10th and 50th percentile in 39\% and greater than the 50th percentile in 13\%. Ferritin > 50th percentile was more common in anemic men (24\%) than in anemic women (9\%; P > 0.20). Macrocytic anemia with concurrent B12 or folate deficiency was rare (3\%). Elevated ESR was observed in patients with ferritin < 10th percentile and >50th. A gluten-free diet resulted in increased serum ferritin in iron-deficient patients, and decreased ferritin levels in those with high ferritin (r(2) = 0.46, P < 0.001). Although anemia is still a common presentation of celiac disease, nutritional deficiencies alone do not explain this phenomenon in all cases; inflammation appears to contribute as evidenced by the presence of anemia of chronic disease in some individuals.
