Case 3-2007: A Boy with Respiratory Insufficiency

Abstract

n engl j med 356;22 www.nejm.org may 31, 2007 2329 To the Editor: In the Case Record of a patient with respiratory insufficiency, presented by Boyer et al. (Jan. 25 issue),1 the discussants do not mention a condition known to be associated with idiopathic pulmonary hemosiderosis and to have implications for its management: celiac disease. The association is referred to as the Lane–Hamilton syndrome.2 It is important to recognize this condition, since treatment of celiac disease with a gluten-free diet could lead to the remission of idiopathic pulmonary hemosiderosis.3 Although both celiac disease and idiopathic pulmonary hemosiderosis are believed to be immunologically mediated, the pathogenetic link between them is not clear. A recent systematic review identified 20 patients with the Lane–Hamilton syndrome.4 Of these, 16 had been prescribed a gluten-free diet, with improvement documented in 12. Patients with idiopathic pulmonary hemosiderosis should be screened for celiac disease, even in the absence of gastrointestinal symptoms, by means of serologic testing for antiendomysial antibodies. If the test is positive, an intestinal biopsy should be carried out to confirm the disease, because a gluten-free diet is very effective for the regression of both celiac disease and idiopathic pulmonary hemosiderosis.
