title: Response to letter: folate deficiency in Crohn's disease.
abstract: Folate deficiency in patients with Crohn's disease may be due to a combination of factors: poor diet, malabsorption, increased requirements due to inflammation of the mucosa, and the taking of certain drugs as sulfasalazine and methotrexate. A significant proportion of patients with Crohn's disease suffer from folate deficiency, suggesting that regular screening should be performed.
