Assessment of iron status and iron deficiency anemia in patients with celiac, a single center experience

This study aimed to assess the status of iron stores and the frequency of iron deficiency anemia in Celiac disease (CD) patients referred to the Golestan Research Center of Gastroenterology and Hepatology, Gorgan, Iran.

Studies have shown that nutritional deficiencies affect 20-38% of patients with CD due to malabsorption and as a result of a gluten-free diet.

In this study, 59 out of 100 CD patients were assessed. The presence and severity of anemia were determined using the concentration of serum hemoglobin according to WHO criteria. The status of body iron stores was also assessed based on serum ferritin levels.

Mean and SD of age, duration of disease, serum hemoglobin, ferritin, TIBC, and serum iron were 39.9±11.9 years, 69.8±45.4 months, 12.6±1.99 g/dl, 54.3±55.3 mg/dL, 365.9±49.1 μg/dL, and 84.1±37.1 μg/dL, respectively. 68.42% had no anemia, 19.3% had mild anemia, 8.77% had moderate anemia, and 3.51% had severe anemia. 25.42% of patients had depleted iron stores, 71.19% had normal iron stores, and 3.39% were exposed to iron overload. There was a statistically significant correlation between serum hemoglobin and the duration of disease diagnosis (P=0.037, r=0.302).

In this study, 31.58% of CD patients on a gluten-free diet had some degree of anemia. In addition, 25.42% of patients had depleted iron stores. These results suggest that CD patients should be evaluated for iron status, even with a gluten-free diet.
