This typically occurs 4-12 hours after exposure to the allergens 3). Most cases of hypersensitivity pneumonitis develop only after many years of continuous or intermittent inhalation of the inciting agent (e.g. An estimated 85 to 95 percent of people exposed to causative substances either never develop hypersensitivity pneumonitis or they experience a mild immune reaction with no obvious signs or symptoms or disease. The 1, 3, and 5-year survival rates were 95 %, 81.2% and 69.3 %, respectively 11). Hypersensitivity pneumonitis (HP) happens if your lungs develop an immune response – hypersensitivity - to something you breathe in which results in inflammation of the lung tissue - pneumonitis. The life expectancy cannot be determined. Symptoms may begin after patients return to an environment from which they have been absent for a while (e.g. Hypersensitivity pneumonitis is a rare immune system disorder that affects the lungs.
