: To study the difference in incidence and risk of fragility fractures between rheumatoid arthritis (RA) patients followed up early in the disease and the general population in Sweden; and the fracture risk changes in RA patients diagnosed in the 1990s and 2000s because of earlier, more potent pharmacological treatment in the later period.: Patients with early RA were recruited from the BARFOT cohort, a Swedish multicentre observational study of early RA patients (n = 2557). All patients fulfilled 1987 American College of Rheumatology criteria and were included between 1992 and 2006. Each patient was matched by gender, age, and residential area with four controls from the general population (n = 10 228). Fractures of forearm, upper arm, and hip were identified by ICD-9 and ICD-10 codes through Swedish national medical registries.: During follow-up of 12.9 ± 4.7 years (mean ± sd), 14% (n = 470) of RA patients and 11% (n = 1418) of controls experienced a fracture (p < 0.001). When dividing the patients and controls into two groups according to inclusion period, an 8 year follow-up time was used. RA patients included in the 1990s had a higher incidence rate (IR) of hip and other fractures. RA patients included in the 2000s had a higher IR of all fracture sites. The hazard ratio of fractures was 1.4 in the total RA cohort, and the risk was increased in both the 1990s and 2000s.: We observed an increased risk of fragility fractures in RA patients diagnosed in both the 1990s and 2000s, despite patients in the 2000s obtaining potent pharmacological treatment early in the disease.
: 目的:研究瑞典早期发病的类风湿关节炎(RA)患者与普通人群脆性骨折发生率和风险的差异;以及由于后期更有效的药物治疗而在 20 世纪 90 年代和 21 世纪初诊断出的 RA 患者的骨折风险变化。: 方法:早期 RA 患者从 BARFOT 队列中招募,这是一项针对早期 RA 患者的瑞典多中心观察性研究(n=2557)。所有患者均符合 1987 年美国风湿病学会标准,并于 1992 年至 2006 年期间纳入研究。每位患者均按照性别、年龄和居住地区与来自普通人群的 4 名对照者(n=10228)相匹配。通过瑞典国家医疗登记系统,用 ICD-9 和 ICD-10 代码确定前臂、上臂和髋部骨折。: 结果:在 12.9±4.7 年(平均±标准差)的随访中,14%(n=470)的 RA 患者和 11%(n=1418)的对照者发生了骨折(p<0.001)。当根据纳入时间将患者和对照者分为两组时,使用了 8 年的随访时间。纳入 20 世纪 90 年代的 RA 患者髋部和其他骨折的发生率较高。纳入 2000 年代的 RA 患者所有骨折部位的发生率较高。总的 RA 队列骨折的危险比为 1.4,20 世纪 90 年代和 21 世纪 00 年代风险均增加。: 结论:尽管 2000 年代的患者在疾病早期就获得了有效的药物治疗,但我们观察到 20 世纪 90 年代和 21 世纪 00 年代诊断出的 RA 患者脆性骨折的风险增加。
