OBJECTIVE
To estimate the prevalence and incidence of multimorbidity (MM) in a population-based cohort of patients with rheumatoid arthritis (RA) compared to subjects without RA.
METHODS
Between 1999-2013, residents of Olmsted County, Minnesota with incident RA who met the 1987 American College of Rheumatology criteria were compared to age- and sex-matched non-RA subjects from the same population. Twenty-five chronic comorbidities from a combination of the Charlson, Elixhauser, and Rheumatic Disease Comorbidity Indices were included, excluding rheumatic comorbidities. The Aalen-Johansen method was used to estimate the cumulative incidence of MM (MM2+; ≥ 2 chronic comorbidities) or substantial MM (MM5+; ≥ 5), adjusting for the competing risk of death.
RESULTS
The study included 597 patients with RA and 594 non-RA subjects (70% female, 90% White, mean age 55.5 yrs). At incidence/index date, the prevalence of MM2+ was higher in RA than non-RA subjects (38% RA vs 32% non-RA, = 0.02), whereas prevalence of MM5+ was similar (5% RA vs. 4% non-RA, = 0.68). During follow-up (median 11.6 yrs RA, 11.3 yrs non-RA), more patients with RA developed MM2+ (214 RA vs 188 non-RA; adjusted HR 1.39, 95% CI 1.14-1.69). By 10 years after RA incidence/index, the cumulative incidence of MM2+ was 56.5% among the patients with RA (95% CI 56.5-62.3%) compared with 47.9% among the non-RA (95% CI 42.8-53.7%). Patients with RA showed no evidence of increase in incidence of MM5+ (adjusted HR 1.17, 95% CI 0.93-1.47).
CONCLUSION
Patients with RA have both a higher prevalence of MM at the time of RA incidence as well as increased incidence thereafter.
目的
在类风湿关节炎（RA）患者的基于人群队列中，与无 RA 的患者相比，估计多种合并症（MM）的患病率和发病率。
方法
1999-2013 年，在明尼苏达州奥姆斯特德县发现的符合 1987 年美国风湿病学会标准的 RA 患者与同一人群中年龄和性别匹配的非 RA 患者进行了比较。纳入了 Charlson、Elixhauser 和风湿性疾病合并症指数的组合中的 25 种慢性合并症，不包括风湿性合并症。使用 Aalen-Johansen 方法估计 MM（MM2+；≥2 种慢性合并症）或大量 MM（MM5+；≥5 种）的累积发病率，调整死亡的竞争风险。
结果
研究纳入了 597 例 RA 患者和 594 例非 RA 患者（70%为女性，90%为白人，平均年龄为 55.5 岁）。在发病/指数日期，RA 患者的 MM2+患病率高于非 RA 患者（38%RA 比 32%非 RA， = 0.02），而 MM5+的患病率相似（5%RA 比 4%非 RA， = 0.68）。在随访期间（RA 中位数为 11.6 年，非 RA 中位数为 11.3 年），更多的 RA 患者发生了 MM2+（214 例 RA 比 188 例非 RA；调整后的 HR 为 1.39，95%CI 为 1.14-1.69）。在 RA 发病/指数后 10 年，RA 患者的 MM2+累积发病率为 56.5%（95%CI 为 56.5-62.3%），而非 RA 患者为 47.9%（95%CI 为 42.8-53.7%）。RA 患者的 MM5+发病率无增加迹象（调整后的 HR 为 1.17，95%CI 为 0.93-1.47）。
结论
RA 患者在发病时既有更高的 MM 患病率，发病后又有更高的发病率。
