目标。目的了解日本多发性肌炎/皮肌炎（PM/DM）患者的数量、患病率和发病率。利用2003 - 2010年全国难治性疾病登记系统电子数据库，确定PM/DM流行病例数和发病病例数。采用电子数据输入率建立登记病例总数。据估计，2010年日本PM/DM患者总数和患病率分别为1.7万/ 10万人和13.2 / 10万人。PM/DM的患病率为每10万人10至13人，并有随时间增加的趋势。PM/DM的发病率估计在10-13 / 100万人年之间，2003年除外。我们最近首次在日本全国人口水平上报告了PM/DM的患病率和发病率。由于流行率最近似乎有所增加，因此需要继续监测这些流行病学特征。
Objectives. To estimate the number of patients with polymyositis/dermatomyositis (PM/DM) in Japan and the prevalence rate and incidence rate of the disease.Methods. The electronic database in the nationwide registration system on intractable diseases from 2003 to 2010 was utilized to identify the number of prevalent and incident cases of PM/DM. The electronic data entry rate was used to establish the total number of registered cases.Results. The estimated total number of patients with PM/DM and the prevalence rate in Japan in 2010 were 17,000 and 13.2 per 100,000 population, respectively. The prevalence of PM/DM ranged from 10 to 13 per 100,000 population with a trend toward increasing over time. The incidence of PM/DM was estimated within the range 10-13 per 1,000,000 person-years, except for 2003.Conclusions. We report the prevalence and incidence of PM/DM recently in Japan for the first time at the nationwide population level. Because the prevalence seems to be increasing recently, continued monitoring of these epidemiologic features is required.
