Results from the global and UCSF registries
As of April 18, 334 cases were in the, with 121 patients (36%) in the database having both COVID-19 and RA, 33 patients (10%) with psoriatic arthritis, 58 patients (17%) with systemic lupus erythematosus, 28 patients (8%) with axial spondyloarthritis, 27 patients (8%) with vasculitis, and 19 patients (6%) with Sjögren’s syndrome. There were less than five cases reported for patients with the following rheumatic diseases: inflammatory myopathy, ocular inflammation, other inflammatory arthritis, polymyalgia rheumatica, sarcoidosis, systemic sclerosis, osteoporosis, psoriasis, isolated pulmonary capillaritis, gout, and autoinflammatory disease. A majority of the patients in the registries are women (74%) aged younger than 65 years (78%) and are white (52%).
The most common comorbid conditions among patients in the registry are hypertension (33%), lung disease (18%), diabetes (11%), cardiovascular disease (10%), chronic renal insufficiency or end-stage renal disease (7%), morbid obesity (7%), and cancer (4%). Before being diagnosed with COVID-19, 219 patients (66%) in the registry were taking conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), which included antimalarials, azathioprine, cyclophosphamide, cyclosporine, leflunomide, methotrexate, mycophenolate mofetil/mycophenolic acid, sulfasalazine, and tacrolimus. A total of 122 patients (37%) were taking biologic DMARDs, 101 patients were taking glucocorticoids (30%), 86 patients (26%) were taking hydroxychloroquine, 41 patients (12%) were taking NSAIDs, and 18 patients (5%) were taking a Janus kinase inhibitor.
The most recent data from the registry show that 128 patients (38%) have been hospitalized for COVID-19, and 19 patients (6%) have died. Although 104 patients (31%) resolved their infections, 177 patients (53%) have a COVID-19 infection status of “unresolved,” and 53 patients (16%) have an unknown infection status.

As of April 21, 249 cases were in the, including 110 hospitalizations (44%) and 37 deaths (15%). Overall, 64% of these patients were women, and they had a median age of 60 years.
The top five diagnoses of these patients were RA (39%), psoriatic arthritis (15%), spondyloarthritis (9%), systemic lupus erythematosus (9%), and gout (5%). A total of 27% had no reported comorbidities, while lung disease occurred in 26%, hypertension in 34%, diabetes in 11%, and cardiovascular disease on 11%. The registry also reported use of any DMARD in 80%, including 62% on csDMARDs, 31% on biologics, and 2% on targeted synthetic DMARDs.
Ten authors in the Lancet Rheumatology paper reported personal and institutional relationships in the form of grants, corporate sponsorships, advisory board memberships, investigator appointments, speaker’s bureau positions, personal fees, and consultancies for a variety of pharmaceutical companies, agencies, societies, and other organizations. The other authors reported no relevant conflicts of interest.
