No systematic studies have been carried out on the association of nutritional status with the severity of mucosal villous atrophy in newly diagnosed celiac disease patients. We examined the nutritional status of 40 adult patients with newly diagnosed celiac disease classified according to the grade of villous atrophy: partial, subtotal, and total. Nutritional status was determined by food records as well as by anthropometric and biochemical measurements. Anthropometric results did not differ among the three atrophy groups, but serum ferritin and erythrocyte folate were lower in patients with total villous atrophy than in the other groups. Most of the abnormal biochemical values were normalized during 1 y of a gluten-free diet; villous atrophy healed concomitantly. To conclude, patients with total mucosal villous atrophy at diagnosis had low erythrocyte folate and serum ferritin values, but no other major differences were found in nutritional status among celiac disease patients with different grades of villous atrophy.
