Background: People with multiple sclerosis (pwMS) have increased comorbid disease (CMD) risk. Most previous studies have not considered overall CMD burden. Objective: To describe lifetime CMD burden among pwMS. Methods: PwMS identified using Swedish registers between 1968 and 2012 (n = 25,476) were matched by sex, age, and county of residence with general-population comparators (n = 251,170). Prevalence, prevalence ratios (PRs), survival functions, and hazard ratios by MS status, age, and time period compared seven CMD: autoimmune, cardiovascular, depression, diabetes, respiratory, renal, and seizures. Results: The magnitude of the PRs for each CMD and age group decreased across time, with higher PRs in earlier time periods. Before 1990, younger age groups had higher PRs, and after 1990, older age groups had higher PRs. Male pwMS had higher burden compared with females. Overall, renal, respiratory, and seizures had the highest PRs. Before 2001, 50% of pwMS received a first/additional CMD diagnosis 20 years prior to people without MS, which reduced to 4 years after 2001. PwMS had four times higher rates of first/additional diagnoses in earlier time periods, which reduced to less than two times higher in recent time periods compared to people without MS. Conclusion: Swedish pwMS have increased CMD burden compared with the general population, but this has reduced over time.

1968-2012 年 MS 患者的共病疾病负担:一项基于瑞典登记册的队列研究

背景:多发性硬化症 (pwMS) 患者的合并症 (CMD) 风险增加。大多数以前的研究没有考虑整体 CMD 负担。目的:描述 pwMS 的终生 CMD 负担。方法:使用 1968 年至 2012 年之间的瑞典登记册(n = 25,476)确定的 PwMS 按性别、年龄和居住县与一般人口比较对象(n = 251,170)进行匹配。MS 状态、年龄和时间段的患病率、患病率比 (PR)、生存函数和风险比比较了七种 CMD:自身免疫、心血管、抑郁、糖尿病、呼吸系统、肾脏和癫痫发作。结果:每个 CMD 和年龄组的 PR 的大小随着时间的推移而下降,早期的 PR 较高。1990 年之前,年龄较小的人群 PRs 较高,而 1990 年以后,年龄较大的人群 PRs 较高。与女性相比,男性 pwMS 的负担更高。总体而言,肾脏、呼吸系统和癫痫发作的 PR 最高。2001 年之前,50% 的 pwMS 在没有 MS 的人之前 20 年接受了首次/额外的 CMD 诊断,在 2001 年之后减少到 4 年。与没有 MS 的人相比,最近一段时间内高出两倍以上。结论:与一般人群相比,瑞典 pwMS 增加了 CMD 负担,但随着时间的推移,这种负担有所减轻。PwMS 在早期的首次/额外诊断率高出四倍,与没有 MS 的人相比,在最近的时间段内降低到不到两倍。结论:与一般人群相比,瑞典 pwMS 增加了 CMD 负担,但随着时间的推移,这种负担有所减轻。PwMS 在早期的首次/额外诊断率高出四倍,与没有 MS 的人相比,在最近的时间段内降低到不到两倍。结论:与一般人群相比,瑞典 pwMS 增加了 CMD 负担,但随着时间的推移,这种负担有所减轻。
