Clinical and prognostic aspects in hypersensitivity pneumonitis

Abstract

Introduction.Hypersensitivity pneumonitis (HP) is a type of interstitial lung disease that occurs following sensitization to an inhaled organic antigen. Although previously classified as acute, subacute and chronic, this classification has not proven to be a good prognostic tool. Therefore, lately the use of fibrotic hypersensitivity pneumonitis (FHP) and nonfibrotic hypersensitivity pneumonitis (NFHP) classification is recommended. Purpose. To study the differences in clinical, diagnostic and prognostic features in patients with fibrotic and nonfibrotic hypersensitivity pneumonitis. Material and methods. We have identified 39 patients, with mean age 47 ± 15 years diagnosed with HP in Chiril Draganiuc Institute of Phtisiopneumology during 2017-2021. Patiens were were analyzed by: antigen exposure history, imaging data, bronchoalveolar lavage (BAL), functional respiratory tests.
