[ALLERGIC ALVEOLITIS [ARTICLE IN POLISH]].

Area of Science:

• Pulmonary Medicine
• Immunology
• Occupational Health

Background:

• Allergic alveolitis (AA) is a group of interstitial lung diseases resulting from chronic inhalation of antigens.
• It presents diagnostic challenges due to varied symptoms and severity, affecting 4-15% of interstitial lung disease cases.
• Farmer's lung, a type of hypersensitivity pneumonitis, is the most common form of AA, often linked to occupational exposures.

Purpose of the Study:

• To review the immunologic background, diagnosis, clinical presentation, and management of allergic alveolitis.
• To highlight the importance of antigen exposure in disease progression and prognosis.
• To discuss therapeutic strategies and prognostic factors in allergic alveolitis.

Main Methods:

• Literature review of allergic alveolitis, focusing on its pathogenesis, clinical features, and treatment.
• Analysis of disease course based on antigen exposure type and duration.
• Evaluation of diagnostic challenges and prognostic indicators.

Main Results:

• Antigen inhalation triggers immune complexes, initiating acute reactions and potentially leading to chronic endolobular fibrosis, particularly in upper lung lobes.
• The acute form, characterized by fever and dyspnea, typically resolves within 24-48 hours after antigen cessation; severe cases may require short-term corticosteroids.
• Chronic AA often progresses to severe dyspnea and cough, with limited treatment options; prednisone may be used in rapidly progressing cases but often fails to halt fibrosis.

Conclusions:

• Avoiding antigen exposure is the primary therapeutic strategy for allergic alveolitis.
• Early diagnosis is crucial for a favorable prognosis in the acute form.
• The chronic form frequently leads to pulmonary fibrosis and respiratory insufficiency, emphasizing the need for preventative measures and further research into effective treatments.
