What impact do swallowing disorders have on the survival of patients with inflammatory myopathy?

Partager sur

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.
