Corticosteroids are usually taken as a pill. x Orphanet: Hypersensitivity pneumonitis. The morbidity associated with prednisone has motivated the search for alternative therapies. Treatment involves avoidance of causative agent and use of corticosteroids. In the absence of small airways disease, irrespective of the morphological pattern of radiological fibrosis, HRCT is indeterminate for fibrotic hypersensitivity pneumonitis. In clinical practice the goal is not to reach a definite diagnosis at any cost but to achieve a working diagnosis with a sufficient degree of likelihood that allows the commencement of therapy, while minimising the potential risk of diagnostic interventions.

Here you can see if there is any natural remedy and/or treatment that can help people with Hypersensitivity Pneumonitis . The classification of hypersensitivity pneumonitis into acute, subacute, and chronic is replaced by two categories, non-fibrotic and fibrotic hypersensitivity pneumonitis since the boundaries among the previous categories are not always clear. However, the degree of BAL lymphocytosis alone plays an important role in defining clinical probability. In these abnormalities, besides air trapping and the three-density pattern, mosaic attenuation is also included. Corticosteroid therapy may be indicated for acute symptomatic relief and may accelerate the initial recovery in persons with severe disease. Given the high variability in the type of inciting agents across different geographical areas, it is extremely difficult, if not impossible, to have such a panel with global applicability.
