Autoimmune-related respiratory disorders

Autoimmune-related respiratory disorders include conditions in which the immune system targets lung tissue or associated structures, leading to inflammation, fibrosis, or airway obstruction. Examples include connective tissue disease-associated interstitial lung disease, vasculitis involving pulmonary vessels, and autoimmune-mediated bronchial disorders. Symptoms can range from chronic cough, dyspnea, and fatigue to recurrent infections or hemoptysis, depending on disease severity and organ involvement. Early recognition and accurate diagnosis are critical, as these disorders can progress rapidly and result in irreversible lung damage. Evaluation typically combines clinical assessment, laboratory markers of autoimmunity, imaging studies, and tissue biopsy when indicated.

Management focuses on controlling immune-mediated injury while preserving lung function. Immunosuppressive therapies, including corticosteroids and disease-modifying agents such as azathioprine, mycophenolate, or rituximab, are commonly employed. Supportive care, including oxygen therapy, pulmonary rehabilitation, and treatment of secondary infections, is essential to optimize patient well-being. Multidisciplinary coordination among pulmonologists, rheumatologists, and immunologists ensures that therapy is tailored to the specific disorder and disease severity. Patient education regarding adherence, symptom monitoring, and early reporting of complications enhances outcomes. Advances in targeted immunotherapy and biomarker-guided treatment are further improving prognosis in autoimmune-related respiratory disorders.
