BACKGROUND: Avian antigen is a common cause of hypersensitivity pneumonitis (HP). Inhalation challenge with pigeon serum and pigeon dropping extract (PDE) elicits a hypersensitivity reaction in patients with bird-related hypersensitivity pneumonitis (BRHP), but the antigenic components in these materials have yet to be fully elucidated. Hypersensitivity pneumonitis (HP), also called extrinsic allergic alveolitis, is a syndrome characterized by diffuse inflammation of lung parenchyma and airways in response to the inhalation of antigens to which the patient has been previously sensitized. Hypersensitivity pneumonia is an immune-mediated lung parenchymal injury occurring in response to repeated inhalation of an antigen. Antigens implicated include animal proteins, fungi, amoeba, bacteria, medications and chemicals.

We report a case of a 44-year-old Sri Lankan lady presenting with pro-gressive severe breathlessness due to pigeon fan-cier’s lung. Pigeon breeder's lung is a form of hypersensitivity pneumonitis, which is caused by repetitive exposure to pigeon antigen. The clinical manifestations are classified according to the phase, which is acute, subacute, or chronic. The diagnosis is based on the clinical picture, environmental and patient history, physical exam, and the appropriate studies.… Pigeon Breeder's Lung (Pigeon Breeder Hypersensitivity pneumonitis (HP) is an immunologically mediated lung disease due to the repetitive inhalation of antigens. Most new cases arise from residential exposures, notably to birds, and are thus more difficult to recognise. The present authors report a 59-yr-old male who complained of dyspnoea and cough while being treated with amiodarone. Pulmonary function tests revealed restriction Hypersensitivity pneumonitis (HP) or extrinsic allergic alveolitis (EAA) is a rare immune system disorder that affects the lungs.

Acute and subacute HP represent the most active forms of the disease which may … Bronchiolitis in chronic pigeon breeder’s disease: Morphologic evidence of a spectrum of small airway lesions in hypersensitivity pneumonitis induced by avian … 2020-10-08 Pérez-Padilla R, Salas J, Chapela R, et al.

Children are more likely to be affected when they share living space with a backyard poultry or pigeon breeding. A 12-year-old girl with persistent cough for 3 years and dyspnea for 2 years. She was dignosed to be having allergy to pigeon droppings, based on reports of lung biopsy and allergy testing. Pigeon breaders’ disease should be Pigeon breeders’ disease (PBD) is one of the most widespread forms of hypersensitivity pneumonia [1], described infrequently in children. We describe a girl with chronic hypersensitivity pneumonia, who presented with prolonged cough and progressive dyspnea. Background: Avian antigen is a common cause of hypersensitivity pneumonitis (HP).

1 The most common antigens are molds, thermophilic bacteria, and animal proteins. The category of animal proteins is almost always avian (bird) antigens.
