Japanese clinicians studied dysphagia and other swallowing disorders in 254 patients with one of the forms of myositis (dermatomyositis, polymyositis, others), excluding inclusion myositis:
- a functional scale, the Food Intake Level Score, was used to quantify the importance of these disorders and to assess their impact on survival;
- 10% of the cohort had dysphagia;
- taken as a whole, the excess mortality observed in this group is more the result of age and the presence of comorbidities than of the myositis itself;
- only patients with very severe dysphagia have a reduction in life expectancy.
