ABSTRACT
The natural course of progressive neuromuscular diseases can be complicated by respiratory muscle involvement. In muscular dystrophies such as Duchenne muscular dystrophy and myotonic dystrophy, respiratory muscle involvement is common. In others such as Becker, limb-girdle, and facioscapulo-humeral dystrophies, respiratory muscle involvement is infrequent and generally occurs in the more severe cases. Recently, it was reported that a mutation in the dysferlin gene and/or dysferlin deficiency causes proximal and distal forms of muscular dystrophy, which are known by the term dysferlinopathy. We describe a case of severe weakness of both limb-girdle and respiratory muscles in a patient who was carrier of the dysferlin gene mutation and who also had COPD. We suggest that the systemic inflammatory response of COPD and the dysferlin deficit interact and are responsible for both the skeletal and respiratory muscle impairment.
