Overview
Epidemiology and Demographics
Incidence
- The incidence of polymyositis and dermatomyositis is approximately 2 per 100,000 individuals worldwide.[1]
- In 2010, the incidence of polymyositis and dermatomyositis was estimated to be 1-1.3 cases per 100,000 individuals in Japan annually.[2]
Prevalence
- The prevalence of polymyositis and dermatomyositis is approximately 5-22 per 100,000 individuals worldwide.[1]
- In 2003, the prevalence of polymyositis and dermatomyositis was estimated to be 21.5 cases per 100,000 individuals in Quebec.[3]
- In 2010, the prevalence of polymyositis and dermatomyositis was estimated to be 13.2 cases per 100,000 individuals in Japan.[4]
Case-fatality rate/Mortality rate
- In [year], the incidence of [disease name] is approximately [number range] per 100,000 individuals with a case-fatality rate/mortality rate of [number range]%.
- The case-fatality rate/mortality rate of [disease name] is approximately [number range].
- The 5-year survival rate for polymyositis is 75% and for dermatomyositis is 63%.[4]
- The median survival for polymyositis is 11.0 years and that for dermatomyositis is 12.3 years.[4]
Age
- Patients of all age groups may develop polymyositis and dermatomyositis.
- Polymyositis and dermatomyositis commonly affects patients in 40-50 years of age.
Race
