[Janus kinase inhibitors in immunoinflammatory rheumatic diseases].

Despite great advances in the diagnosis and treatment of immunoinflammatory rheumatic diseases, which have led to a significant improvement in the prognosis in many patients, the fundamental medical problems of this pathology the restoration of the quality of life and the reduction of mortality to the population level are far from being resolved. This served as a stimulus for the study of new approaches to the pharmacotherapy of IVRD, one of which is associated with the use of low molecular weight chemically synthesized drugs that inhibit intracellular "signaling" molecules Janus kinase. Modern advances regarding the use of Janus kinase inhibitors in the treatment of immunoinflammatory rheumatic diseases and COVID -19 are considered.

Coronavirus Infection 2019 (COVID-19) and Autoimmunity.

The pandemic of coronavirus disease 2019, etiologically associated with the SARS-CoV-2 virus, has drawn the attention of the medical community to new clinical and fundamental problems in the immunopathology of human diseases. During a detailed analysis of the clinical manifestations and immunopathological disorders in COVID-19, it became apparent that SARS-CoV-2 infection is accompanied by the development of a wide range of extrapulmonary clinical and laboratory disorders, some of which are characteristic of immunoinflammatory rheumatic diseases and other human autoimmune and autoinflammatory diseases. All this taken together served as a theoretical justification for the repositioning of anti-inflammatory drugs in COVID-19, previously specifically designed for the treatment of immunoinflammatory rheumatic diseases. The prospects for studying the autoimmune mechanisms of COVID-19 and the possibility of anti-inflammatory therapy are discussed.

Safety of COVID-19 vaccines in patients with immunoinflammatory rheumatic diseases (preliminary data)

Objective: to assess the safety of COVID-19 vaccines in patients with immunoinflammatory rheumatic diseases (IRD) in real clinical practice. Patients and methods. A cross-sectional study of patients with IRD, who were admitted to V.A. Nasonova Research Institute of Rheumatology for inpatient or outpatient treatment. All patients received at least 1 dose of vaccine against COVID-19 (main group). The control group consisted of vaccinated persons without IRD. All participants were interviewed by the researcher by filling out a unified questionnaire, additional information was obtained from medical records. Results and discussion. The study included 204 patients with IRD (151 of them were vaccinated with Sputnik V, 31 with Sputnik Light, 19 with СoviVac, 3 with EpiVacCorona;173 patients received the second component of vaccine) and 131 subjects without IRD (101 of them were vaccinated with Sputnik V, 17 – CoviVak, 5 – Sputnik Light, 2 – EpiVacCorona, 6 – Pfizer/BioNTech;124 patients received the second component of the vaccine). The number of patients with IRD who had both local and systemic reactions after administration of the first component of the vaccine was significantly less than in the control group (19.6 and 38.9%, respectively;p<0.001). Similar differences were noted after the administration of the second component (15.6 and 27.4%, respectively;p=0.013). Adverse events (AEs) such as pain at the injection site without restriction of movement, weakness, fever, arthralgia/myalgia and chills were significantly more common in the control group after the administration of the first component of the vaccine. After complete immunization, AEs were absent in 35.8% of patients with IRD and in 21% of controls (p=0.006). Exacerbations of IRD and new autoimmune phenomena were not registered in any case. Conclusion. According to preliminary data, vaccination against COVID-19 in patients with IRD appears to be quite safe. Further studies are needed to investigate the safety, immunogenicity, and clinical efficacy of COVID-19 immunization in rheumatic patients. © 2022, Ima-Press Publishing House. All rights reserved.
