Evaluation of Cases with Hypersensitivity Pneumonia

Abstract

Hypersensitivity pneumonia (HP) ,classified in the category of interstitial lung diseases, occurs asa aresult of the immunological reaction that develops in the lung parenchyma with repeated inhalation of lung-sensitive antigen. This immunological reaxtion is a combination of type 3 and type 4 overreaction. Although the severity of the disease varies with the density of the inhaled antigen, more than 300 antigens have been identified. In diagnosis, it is sufficient to determine the exposure in the history and observe distinct ground glass areas and nodular opacities in the upper and middle lobes on High-Resolution Computed Thoracic Tomography (HRCT). In our case series, the complaints of all 11 patients . The diagnosis was made by observing ground glass areas and patchy consolidation in the patients' HRCTs and by detecting exposure in their histories. Of the 11 patients, 4 were bird feeders and 5 were engaged in animal husbandry. Two patients were working as carpenters. HP was diagnosed because the radiological images of the patients were typical and exposure was detected.
