Some patients with SLE or Gougerot-Sjögren's disease (GSD) receive long-term treatment with hydroxychloroquine (HCQ), sometimes combined with immunosuppressive therapy (IS). This study sought to assess whether long-term HCQ therapy that had been initiated long before the COVID-19 pandemic had a protective or adverse effect on COVID-19 risk, severity of infection or immunity protection.
This prospective multicentre study included 547 patients with SLE, GSD, autoimmune hepatitis, primary biliary cholangitis or cured viral hepatitis C divided into four groups according to HCQ (+/-) and IS (+/-) intake prior to the pandemic: HCQ+IS+ (n=112), HCQ+IS- (n=121), HCQ-IS+ (n=115) and HCQ-IS- (n=199). When COVID-19 vaccination was possible, patients were vaccinated as recommended. Vaccination efficacy was prospectively assessed on the basis of the postvaccination antibody titre.
Compared with HCQ+IS+ patients, HCQ-IS+ patients had a decreased risk of COVID-19 infection (p<0.001). Compared with HCQ+IS+ patients, HCQ-IS- patients had a decreased risk of contracting COVID-19 (p<0.001). Patients in the HCQ-IS+ or HCQ-IS- group had a lower risk of symptomatic or severe infection than HCQ+IS+ patients did (p=0.001 and p<0.001, respectively). Only patients who had two or more exposures (to vaccine and/or infection) had an increased likelihood of COVID-19 immunity after the last dose (p<0.001).
HCQ treatment that was initiated before the pandemic did not protect against COVID-19 infection. Moreover, non-exposure to HCQ treatment (combined or not with IS) was associated with decreased risk of COVID-19 infection and of developing a symptomatic or severe infection. HCQ and IS do not influence the vaccine response. Only two or more doses of vaccine result in a good vaccine response.

一些系统性红斑狼疮(SLE)或舍格伦综合征(GSD)患者长期接受羟氯喹(HCQ)治疗,有时联合免疫抑制治疗(IS)。本研究旨在评估在2019冠状病毒病(COVID-19)大流行之前很久就开始的长期HCQ治疗对COVID-19风险、感染严重程度或免疫保护是否有保护作用或不良影响。
这项前瞻性多中心研究纳入了547例SLE、GSD、自身免疫性肝炎、原发性胆汁性胆管炎或已治愈的丙型病毒性肝炎患者,根据大流行前HCQ(+/-)和IS(+/-)的摄入情况分为四组:HCQ+IS+(n = 112)、HCQ+IS-(n = 121)、HCQ-IS+(n = 115)和HCQ-IS-(n = 199)。当可以进行COVID-19疫苗接种时,按照建议为患者接种疫苗。根据接种疫苗后的抗体滴度前瞻性评估疫苗效力。
与HCQ+IS+患者相比,HCQ-IS+患者感染COVID-19的风险降低(p<0.001)。与HCQ+IS+患者相比,HCQ-IS-患者感染COVID-19的风险降低(p<0.001)。HCQ-IS+或HCQ-IS-组患者出现症状性或严重感染的风险低于HCQ+IS+患者(分别为p = 0.001和p<0.001)。只有经历过两次或更多次(疫苗接种和/或感染)暴露的患者在最后一剂疫苗接种后获得COVID-19免疫力的可能性增加(p<0.001)。
大流行前开始的HCQ治疗不能预防COVID-19感染。此外,未接受HCQ治疗(联合或不联合IS)与COVID-19感染风险以及出现症状性或严重感染的风险降低相关。HCQ和IS不影响疫苗反应。只有接种两剂或更多剂疫苗才会产生良好的疫苗反应。
