Evaluation of the respiratory function in myasthenia gravis: an important tool for clinical feature and diagnosis of the disease

Abstract: -Myasthenic gravis may affect both inspiratory and expiratory muscles. Respiratory involvement occurred in almost all patients with myasthenia gravis in all clinical forms of the disease: 332 lung function tests done in 324 myasthenic patients without respiratory symptoms (age 34.6 ± 18.3 years) were examined. Lung volumes analysis showed that all the patients of both sexes with generalized or ocular myasthenia gravis showed "myasthenic pattern". Male patients with "ocular" form only presented the "myasthenic … Show more

“…[3][4][5] Patients with MG often have a "myasthenic pattern" characterized by reduced ventilatory muscle endurance and volumes in lung function tests. 6,7 Patients usually report dyspnea upon extreme effort due to muscle weakness, and ventilatory muscle impairment adversely affects the performance of physical activities and patients' daily lives due to perceived fatigue. 8 The 6-minute walk test )6MWT( has been shown to be relatively reliable in patients with neuromuscular diseases and 6MWT distance )6MWD( was reported to be lower in generalized MG patients than in healthy controls.…”
