Coexistence of bronchial asthma and myasthenia gravis. (Clinical case)

Bronchial asthma and myasthenia gravis are immune-mediated disorders with potential shared pathogenic mechanisms. The coexistence of these conditions creates significant challenges in clinical management. Furthermore, determining the etiology of respiratory symptoms requires a multidisciplinary approach involving pulmonologists and comprehensive pulmonary function testing. Critical diagnostic measures include spirometry with bronchodilator testing to confirm bronchial obstruction and its reversibility, along with assessment of respiratory muscle strength through maximal inspiratory and expiratory pressure (MIP/MEP) measurements to exclude a neuromuscular component of dyspnea. This article presents a clinical case of comorbid bronchial asthma and myasthenia gravis in a 73-year-old female patient.
