Hypersensitivity pneumonitis / hypersensitivity pneumonitis (HP) or extrinsic allergic alveolitis is a group of lung diseases that are mediated by the immunological consequences of repeated exposure of the antigen is dispersed mainly by the particles when inhaled organic or low chemical bermolekul which further provoke hypersensitivity reaction with granulomatous inflammation … several times a day, for several weeks or more) or longer use of opioids can lead to physical dependence and possibly addiction. Learn about interstitial lung disease, including life expectancy and prognosis. Typically, after the disease is recognized, the causative allergen or environment is identified and treatment initiated through avoidance measures and corticosteroids.

European Respiratory Journal Sep 2018, 52 (suppl 62) PA3663; DOI: 10.1183/13993003.congress-2018.PA3663, Rodríguez-Moreno A, Ridao N, García-Ledesma P et-al. Hypersensitivity pneumonitis (HP) is characterized by inflammation of the lung that is induced by chronic exposure to inhaled organic antigens . 1992;159 (3): 469-72. 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. Rudolf K.F. European Respiratory Journal Jun 2018, 51 (6) 1800430; DOI: 10.1183/13993003.00430-2018.

The symptoms of hypersensitivity pneumonitis are divided into three types namely, acute, subacute, and chronic. Hypersensitivity pneumonitis (HP) is an immunologically mediated lung disease resulting from exposure to inhaled environmental antigens. Hypersensitivity pneumonitis: a historical, clinical, and radiologic review. Hypersensitivity pneumonitis (HP) is an immune-mediated syndrome triggered by inhalation of a wide variety of allergens, to which an individual has previously been sensitized. Some small studies found this condition to be slightly more common in women. Prognosis is variable, with a subset of patients developing progressive fibrosis leading to respiratory failure and death. 1 However, there are certain individuals with a much higher likelihood of developing this disease based on substances they are exposed to (e.g. Hypersensitivity pneumonitis may also be caused by fungi or bacteria in humidifiers, heating systems, and air conditioners found in homes and offices. * Due to a revision of the methodology used to determine life expectancy, the estimates presented for 2001–2004 may be different than those previously reported. Hypersensitivity pneumonitis. More than 200 types of interstitial lung diseases exist, such as pulmonary fibrosis. The following are common signs and symptoms of acute, subacute, and chronic hypersensitivity pneumonitis. The 2010 estimates are based on preliminary life-expectancy data. The patient's history of repeated episodes of typical symptoms, hours after exposure to certain environments are important in establishing the diagnosis.
