“…Importantly, some medications used to treat rheumatic diseases, such as hydroxychloroquine and interleukin-6 (IL-6) inhibitors, are being studied for the prevention and/or treatment of COVID-19 and its complications including cytokine-storm. [2][3][4] At present, the implications of COVID-19 for people living with rheumatic diseases remain poorly understood.…”

“…The registry has also provided preliminary data on 80 SLE-patients with COVID-19 and the use of HCQ. Sixty-four percent of the SLE-patients were taking antimalarials prior to the infection with SARS-CoV-2 and admission frequency to the hospital did not differ between HCQ users and non-users [55% (16/29) vs. 57% (29/51), p = ns; χ 2 -test] ( 60 ). This argues against a protective role of HCQ (in the usually administered dose for RMD patients) in SARS-CoV-2 infection, which is also supported by pharmacological in vitro data describing a much higher level needed for effective viral inhibition ( 61 ).…”

“…Data collected through the COVID-19 Global Rheumatology Alliance registry recently confirmed that patients with lupus on baseline therapy with HCQ are not universally protected from COViD-19 5. Therefore, we commend Favalli et al to emphasise the primordial role of physical distancing and the adoption of strict rules for the prevention of contagion, because of the uncertain protection of patients with SLE from severe SARS-CoV-2 infection by HCQ treatment.…”
