HUNTER, Martín et al. Miopatía inflamatoria con compromiso inicial de músculos respiratorios y artritis reumatoidea. Medicina (B. Aires) [online]. 2014, vol.74, n.5, pp.393-396. ISSN 0025-7680.

Inflammatory myopathies comprise a heterogeneous group of subacute, chronic and sometimes acute acquired muscle diseases. The most common inflammatory myopathies seen in practice can be separated into four distinct subsets: polymyositis, dermatomyositis, necrotizing autoimmune myositis and inclusion body myositis. These disorders present as proximal and symmetric muscle weakness but rarely respiratory muscles may also be affected. We report the case of a 39 year-old female with inflammatory myopathy with acute respiratory failure due to alveolar hypoventilation secondary to respiratory muscle dysfunction that required mechanical ventilation. The treatment with steroids, methotrexate and intravenous immune globulin was successful as well as the implementation of non-invasive ventilation as an alternative to endotracheal intubation.
