虽然严重感染是系统性红斑狼疮(SLE)发病率和死亡率的重要原因,但尚未对全国范围内SLE和狼疮肾炎(LN)患者的流行病学进行研究。使用Medicaid Analytic eXtract(MAX)数据库,2000-2006年,我们确定了18-64岁的SLE患者和LN患者。我们使用经过验证的算法确定了住院严重感染和30天死亡率。我们使用Poisson回归计算感染发生率(IR),使用多变量考克斯比例风险模型计算首次感染的风险比(HR),并根据社会人口统计学、药物使用和SLE特异性风险调整指数进行调整。我们确定了33,565例SLE患者和7,113例LN患者。在5,078例SLE患者中有9,078例严重感染,在1,825例LN患者中有3,494例感染。SLE和LN的感染率分别为10.8/100人年和23.9/100人年。在调整后的模型中,我们观察到SLE患者中男性感染的风险高于女性(HR 1.33,95% CI 1.20-1.47),黑人与白人相比(HR 1.14,95% CI 1.06-1.21),糖皮质激素使用者(HR 1.51,95% CI 1.43-1.61)和免疫抑制剂使用者(HR 1.11,95% CI 1.03-1.20)与非使用者相比。与非使用者相比,羟氯喹使用者的感染风险降低(HR 0.73,95% CI 0.68-0.77)。在因感染住院的患者中,30天死亡率为每1,000人年,SLE为21.4人,LN为38.7人。在这个多样化的全国性SLE患者队列中,我们观察到严重感染的巨大负担和许多随后的死亡。
While serious infections are significant causes of morbidity and mortality in systemic lupus erythematosus (SLE), the epidemiology in a nationwide cohort of SLE and lupus nephritis (LN) patients has not been examined. Using the Medicaid Analytic eXtract (MAX) database, 2000-2006, we identified patients 18-64 years with SLE and a subset with LN. We ascertained hospitalized serious infections using validated algorithms, and 30-day mortality rates. We used Poisson regression to calculate infection incidence rates (IR), and multivariable Cox proportional hazards models to calculate hazard ratios (HR) for first infection, adjusted for sociodemographics, medication use, and a SLE-specific risk adjustment index. We identified 33,565 patients with SLE and 7,113 with LN. There were 9,078 serious infections in 5,078 SLE patients and 3,494 infections in 1,825 LN patients. The infection IR per 100 person-years was 10.8 in SLE and 23.9 in LN. In adjusted models, in SLE, we observed increased risks of infection among males compared to females (HR 1.33, 95% CI 1.20-1.47), in Blacks compared to Whites (HR 1.14, 95% CI 1.06-1.21), and glucocorticoid users (HR 1.51, 95% CI 1.43-1.61) and immunosuppressive users (HR 1.11, 95% CI 1.03-1.20) compared with non-users. Hydroxychloroquine users had a reduced risk of infection compared to non-users (HR 0.73, 95% CI 0.68-0.77). The 30-day mortality rate per 1,000 person-years among those hospitalized with infections was 21.4 in SLE and 38.7 in LN. In this diverse, nationwide cohort of SLE patients, we observed a substantial burden of serious infections with many subsequent deaths.
