RESUMO
Background: The ORAL Surveillance trial showed a potentially higher incidence of malignancy and major adverse cardiovascular events (MACEs) associated with tofacitinib than those associated with tumor necrosis factor (TNF) inhibitors (TNFis). However, few studies have compared the safety of non-TNFis or other Janus kinase (JAK) inhibitors (JAKis). This study was aimed at comparing the incidence rates (IRs) of malignancies and MACEs in patients with rheumatoid arthritis (RA) treated using interleukin-6 (IL-6) inhibitors (IL-6is) or JAKis. Methods: We retrospectively analyzed 427 patients with RA who were treated using an IL-6i (n = 273) or a JAKi (n = 154). We determined the IRs of malignancy and MACEs, and the standardized incidence ratio (SIR) of malignancies and investigated factors related to malignancy and MACEs. After adjusting the clinical characteristic imbalance by propensity score matching (PSM), we compared the IRs of adverse events between the JAKi and IL-6i groups. Results: After PSM, the observational period was determined to be 605.27 patient-years (PY), and the median observational period was determined to be 2.28 years. We identified seven cases of malignancy (IR: 2.94 per 100 PY) in the JAKi-treated group and five cases (IR: 1.36 per 100 PY) in the IL-6i-treated group after PSM. The IR of MACEs was 2.56 and 0.83 (per 100 PY) in the JAKi- and IL-6i-treated groups. The IRRs of JAKi-treated patients versus IL-6i-treated patients were 2.13 (95% confidence interval (CI): 0.67-7.42) for malignancy and 3.03 (95% CI: 0.77-15.21) for MACE. There were no significant differences in IRR for malignancy and MACE between both groups after PSM. Univariate and multivariable Cox regression analyses revealed that older age and JAKi use were independent risk factors for malignancy, while older age, hypertension, and JAKi use were independent risk factors for MACEs. The overall malignancy SIR was significantly higher in the JAKi-treated group compared to the general population (2.10/100 PY, 95% CI: 1.23-2.97). Conclusion: The IRs of malignancy and MACE in patients with RA after PSM were comparable between IL-6i-treated and JAKi-treated patients. However, the SIR of malignancy in JAKi treatment was significantly higher than in the general population; therefore, further safety studies comparing JAKi to non-TNFi biologic disease-modifying antirheumatic drugs (bDMARDs) are needed.

SARS-CoV-2 causes mostly mild cases. However, a considerable number of patients develop fatal acute respiratory distress syndrome due to the cytokine storm and imbalanced immune response. Several therapies depending on immunomodulation have been used, including glucocorticoids and IL-6 blockers. However, their efficacy is not perfect with all patients and patients with concomitant bacterial infections and sepsis. Accordingly, studies on different immunomodulators, including extracorporeal techniques, are crucial to save this category of patients. In this review, we overviewed the different immunomodulation techniques shortly, with a brief review of extracorporeal methods.

INTRODUÇÃO: O tocilizumabe, um anticorpo monoclonal humanizado recombinante IgG1 dirigido contra o receptor da interleucina-6 (IL-6, citocina pró-inflamatória), pode representar uma estratégia para a redução da duração ou gravidade da infecção causada por SARS-CoV-2 em pacientes hospitalizados devido as suas propriedades imunossupressoras e potencial de controle sobre a disfunção imunitária e a inflamação. PERGUNTA DE PESQUISA: O uso de tocilizumabe é eficaz e seguro no tratamento de pacientes adultos com COVID-19 hospitalizados, quando comparado as opções terapêuticas recomendadas no Brasil? EVIDÊNCIAS CLÍNICAS: Para seleção das evidências clínicas foi conduzida uma revisão sistemática da literatura em busca de ensaios clínicos randomizados (ECR) e revisões sistemáticas com meta-análises (RSMA) que avaliassem os efeitos do tocilizumabe como monoterapia ou associado aos cuidados usuais - definidos aqui como 'terapia padrão' (corticoesteróides sistêmicos, anticoagulantes, antimicrobianos/antivirais) n
