We conducted a prospective, population based study to examine trends in incidence and prevalence of amyotrophic lateral sclerosis (ALS) in Ireland from 1995 to 2004.
The Irish ALS Register was used to identify Irish residents diagnosed with ALS between the 3 year period from 1 January 1995 to 31 December 1997 and the 3 year period from 1 January 2002 to 31 December 2004.
465 Irish residents were diagnosed with ALS during the study periods. The annual incidence rate of ALS in Ireland remained stable over this time (2.0 cases per 100,000 person-years; 95% CI 1.9, 2.2). Median survival of Irish ALS patients was 16.4 months and did not change during the study period. Demographics and clinical features of the incident and prevalent Irish ALS cohorts were markedly different.
我们开展了一项基于人群的前瞻性研究,以调查1995年至2004年爱尔兰肌萎缩侧索硬化症(ALS)的发病率和患病率趋势。
利用爱尔兰ALS登记册来确定在1995年1月1日至1997年12月31日这3年期间以及2002年1月1日至2004年12月31日这3年期间被诊断为ALS的爱尔兰居民。
在研究期间,465名爱尔兰居民被诊断为ALS。在此期间,爱尔兰ALS的年发病率保持稳定(每10万人年2.0例;95%可信区间1.9,2.2)。爱尔兰ALS患者的中位生存期为16.4个月,在研究期间没有变化。新发病例和现患爱尔兰ALS队列的人口统计学和临床特征明显不同。
