  • Platelet count < 100 x 103 / μL

  • ALT or AST levels > 5 times the upper limit of normal

  • Severe renal failure (CrCr < 30 mL / min)

  • Active bacterial infectious process

  • Active TB, history of not completing treatment against tuberculosis, suspicion of extrapulmonary tuberculosis

  • History of intestinal ulcer or diverticulitis

  • History of hypersensitivity reactions to sarilumab or its excipients

  • Treatment with TNF antagonists

  • Previous treatment with anti‐IL6 in the previous 30 days

  • Chronic prior treatment with corticosteroids at doses greater than 0.5 mg / kg / day of prednisone or equivalent. Yes, inhaled and topical corticosteroids are acceptable
