ALLERGIC ALVEOLITIS Meaning and
Definition
-
Allergic alveolitis, also known as hypersensitivity pneumonitis or extrinsic allergic alveolitis, is a rare immunologically mediated lung disease. It is characterized by inflammation of the alveoli, the small air sacs in the lungs, due to an allergic reaction triggered by inhaling certain substances.
In this condition, the immune system overreacts to the inhalation of allergens such as mold spores, bacteria, fungi, or chemicals present in organic dust from hay, grain, or bird feathers. These allergens are usually encountered in occupational or environmental settings.
Allergic alveolitis often occurs in individuals who are genetically predisposed to developing allergies. When the allergens are inhaled, the immune system produces an excessive immune response, leading to inflammation and damage of the lung tissue.
Symptoms of allergic alveolitis may vary from person to person and can manifest as flu-like symptoms, including fever, cough, shortness of breath, fatigue, and chest tightness. Individuals with chronic exposure to the allergens may develop long-term lung damage, leading to pulmonary fibrosis.
Diagnosis of allergic alveolitis involves a thorough medical history, physical examination, and various tests, such as pulmonary function tests, chest X-rays, blood tests, and sometimes a lung biopsy. Treatment primarily involves avoiding further exposure to the allergens and the use of medications, such as corticosteroids, to manage the symptoms and reduce inflammation. Severe cases may require additional therapies or lung transplantation. Prognosis varies depending on the stage of the disease and the extent of lung damage.

Etymology of ALLERGIC ALVEOLITIS
The word "allergic alveolitis" can be broken down into two parts: "allergic" and "alveolitis".
1. Allergic: The term "allergic" is derived from the Greek word "allos", meaning "other" or "different", combined with the suffix "-ic", which denotes being related to or pertaining to. It describes a condition or reaction caused by an abnormal immune response to usually harmless substances, such as pollen, dust, or certain foods.
2. Alveolitis: The term "alveolitis" comes from the Latin word "alveolus", meaning "small cavity" or "inlet". In medical terminology, it refers to inflammation or irritation of the alveoli, which are the tiny air sacs in the lungs.
