The rapid spread of a new coronavirus infection (COVID-19) requires innovative solutions, including tactics optimization in using genetically engineered and targeted drugs in patients with immuno-inflammatory rheumatic diseases (RD). The authors studied the characteristics of the complex therapy of immuno-inflammatory RD in the COVID-19 pandemic conditions, analyzed the COVID-19 course in patients with RD who received combined therapy with genetically engineered and basic synthetic anti-rheumatic drugs and were under follow-up from March 2020 to March 2021. The researchers found that synthetic basic (methotrexate, leflunomide, etc.), targeted synthetic (tofacitinib, baricitinib, apremilast) and biologic disease-modifying antirheumatic drugs used in the RD treatment, except high-dose glucocorticoids and anti-B cell drugs (rituximab), do not have a negative effect and are not associated with a severe COVID-19 course. The use of interleukin-6 (IL-6) inhibitors is the standard pathogenetic therapy for cytokine release syndrome in COVID-19. Proactive therapy with IL-6 inhibitors provides inhibition of systemic inflammation and contributes to the suppression of cytokine storm syndrome, preventing the development of multiple organ failure and fatal outcome.
