Lane-Hamilton Syndrome in an Adult With Down Syndrome: A Case Report

Abstract

The Lane-Hamilton syndrome (LHS) is an extremely rare association between celiac disease (CD) and idiopathic pulmonary hemosiderosis (IPH), with only a few cases reported in the literature. The authors report a case of a 32-year-old man with Down syndrome who presented to the emergency department with a history of hemoptysis and chronic diarrhea. The complementary investigation revealed iron deficiency anemia and features suggestive of diffuse alveolar hemorrhage on computed tomography (CT) scan of the chest. After excluding all competing diagnosis, the IPH diagnosis was made. The biopsy of the small intestine confirmed CD and the diagnosis of LHS was established. A gluten-free diet and steroids were given to the patient with a very good clinical response. Since there is an established association between IPH and CD, if the diagnosis of IPH is made, it's recommended to screen for CD even in patients without gastrointestinal symptoms.
