Evaluation of the effects of pre-exposure treatment with hydroxychloroquine on the risk of COVID-19 infection and on the efficacy of anti-COVID-19 vaccination during lupus or Gougerot-Sjögren's disease: Prepcov multicentre trial.
Objectives: 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.
Methods: 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.
Results: 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).
Conclusions: 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.
期刊介绍：
Lupus Science & Medicine is a global, peer reviewed, open access online journal that provides a central point for publication of basic, clinical, translational, and epidemiological studies of all aspects of lupus and related diseases. It is the first lupus-specific open access journal in the world and was developed in response to the need for a barrier-free forum for publication of groundbreaking studies in lupus. The journal publishes research on lupus from fields including, but not limited to: rheumatology, dermatology, nephrology, immunology, pediatrics, cardiology, hepatology, pulmonology, obstetrics and gynecology, and psychiatry.
