Almost anything can cause it, including germs, medication, and allergies. Loss of appetite 5. Hypersensitivity pneumonitis (HP), also known as extrinsic allergic alveolitis, is an immune mediated lung disease occurring in response to repeated inhalation of an antigen. Early diagnosis is important to avoid serious complications. Hypersensitivity pneumonitis (HP) is a group of immunologically mediated lung diseases caused by the inhalation of environmental agents in susceptible individuals. Although sensitization to an inhaled antigen as manifested by specific circulating IgG antibodies is necessary for the development of HP, sensitization alone is not sufficient as a defining characteristic, because many sensitized, The incidence and prevalence of HP are variable, depending on geography, occupation, avocation, and. Hypersensitivity pneumonitis (HP) is categorized as acute, subacute, and chronic based on the duration of the illness. Although these categories are not fully satisfactory in capturing this variability, Hypersensitivity pneumonitis has been traditionally categorized as having acute, subacute, and chronic forms. In general, symptoms of acute, or sudden, HP last between 12 hours and several days. While most people who breathe in these antigens don't develop problems, in some people, the body's immune reaction to these particles causes inflammation of the lung. Presentations of acute or subacute HP can be mistaken for respiratory infection. Acute HP Symptoms. The mainstay of treatment for HP is antigen avoidance. Treatments Hypersensitivity pneumonitis usually occurs in people who work in places where there are high levels of organic dusts, fungus, or molds. Because acute HP is generally a self-limited disease after a discrete exposure to an offending antigen, pharmacologic therapy is generally not necessary. Symptoms include fever, chills, malaise, cough, chest tightness, dyspnea, rash, swelling and headache. In chronic hypersensitivity pneumonitis, there are findings of lung fibrosis (eg, lobar volume loss, linear or reticular opacities, or honeycombing), and centrilobular nodules may be absent. A careful occupational and home exposure history should be taken and may be supplemented if necessary by a clinician visit to the work or home environment. Some HP cases are associated … Hypersensitivity pneumonitis is a syndrome of cough, dyspnea, and fatigue caused by sensitization and subsequent hypersensitivity to environmental (frequently occupational) antigens. But in some people who are "hypersensitive," the lungs stay inflamed and cause the symptoms of hypersensitivity pneumonitis. Given the heterogeneity among patients, variability in offending antigens, and differences in the intensity and duration of exposure to antigen, the presentation of Hypersensitivity pneumonitis is accordingly variable. Although the symptomatic disease has been classically divided into acute, subacute, and chronic types, given contradictory definitions, it has been more recently divided in acute/inflammatory type (non-fibrotic hypersensitivity pneumonitis) and chronic/fibrosis type (fibrotic hypersensitivity pneumonitis) 3,13.
