The case reported by Guilpain et al attracted our attention. This case of granulomatosis with polyangiitis on immunosuppressants, including recent maintenance therapy with rituximab (RTX), developed a severe and life-threatening coronavirus-2 (SARS-CoV-2) disease 2019 (COVID-19). The particularity of this observation was the occurrence of a more progressive worsening than observed in most series.1 Herein, we report the observation of three patients with systemic sclerosis (SSc) routinely treated with RTX who were affected by COVID-19 and who also experienced a late clinical worsening to severe pneumonia. RTX is often used off-label in patients with SSc mainly for refractory skin, musculoskeletal or interstitial lung disease. Observational studies reported a safety profile similar to that reported in rheumatoid arthritis.2
Their main disease characteristics are presented in table 1. Patient 1 had early diffuse cutaneous SSc, with positive RNA polymerase-3 antibodies, and severe cutaneous involvement (peak modified Rodnan Skin Score at 32/51) as the main clinical involvement. Patient 2 had long-lasting limited cutaneous SSc with recurrent digital ulcers and inflammatory arthritis as the main disease manifestations. Patient 3 had a limited cutaneous subset evolving from 2 years, with positive RNA polymerase-3 antibodies and persisting arthritis. None of these patients had interstitial lung disease and primary or secondary heart involvement. Regarding the main comorbidities, patient 1 was treated for high blood pressure by perindopril, furosemide and lercanidipine, and patient 2 had chronic renal insufficiency and history …
