Hypersensitivity pneumonitis due to dove antigens in an adolescent.
Hypersensitivity pneumonitis is infrequently reported in children. This article describes a 15-year-old girl who presented with insidious onset of dyspnea and weight loss. A hamster and doves were housed in her bedroom. Chest radiographs showed bilateral nodular infiltrates. Pulmonary function tests showed a restrictive pattern with O2 desaturation at rest. The diagnosis was substantiated by the presence of precipitating antibody to dove serum and droppings and by clinical improvement, along with marked improvement in pulmonary function test, after the doves were removed from her environment. The importance of making an early diagnosis to prevent debilitating fibrotic lung disease is emphasized. A detailed environmental history is essential.
