ABSTRACT
Axial spondyloarthritis (axSpA) is an inflammatory rheumatic disorder that causes chronic pain, primarily in the spine and sacroiliac joints. It is characterized by the presence of type 1 major histocompatibility complex HLA-B27 genetic marker, arthritis in peripheral joints, enthesitis and/or dactylitis and extra-articular manifestations. Current guidelines recommend biological therapy when first-line therapy is not sufficiently effective. The finding that the interleukin (IL)-17 axis is vital for the pathogenesis of axSpA propelled the development of secukinumab, a fully human monoclonal antibody directed against IL-17A. The present review provides evidence on the efficacy and safety of secukinumab in the treatment of radiographic and non-radiographic axSpA from nine randomized controlled phase III trials, as well as evidence from real-world observational analyses. The primary endpoint in six clinical trials was the proportion of patients meeting the Assessment of SpondyloArthritis international Society criteria for either 20% or 40% improvement (ASAS20, ASAS40) at week 16. Significantly more patients achieved the primary endpoint with secukinumab compared with placebo in all the studies except MEASURE 4. Both clinical trials and real-world studies showed significant improvements in the secondary endpoints of disease activity, quality of life, and pain and fatigue relative to placebo. The benefits of secukinumab were generally sustained during longer-term (up to 5 years) treatment. Overall, secukinumab was well tolerated with a low frequency of adverse events and treatment persistence was high in the real-world setting. Although indirect comparisons suggest that secukinumab and adalimumab have comparable efficacy and safety, they are being directly compared in the ongoing SURPASS study. During the current coronavirus disease 2019 (COVID-19) pandemic, it is advisable to continue biological therapy in patients who do not have severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) infection, but interrupt treatment during an infection, reinitiating once the patient has recovered from the infection. In conclusion, secukinumab is a largely safe and effective treatment for radiographic and non-radiographic axSpA.
ABSTRACT
OBJECTIVE: To describe the cohort of patients with inflammatory rheumatic diseases (IRD) hospitalized due to SARS-CoV-2 infection in the Ramón y Cajal Hospital, and to determine the increased risk of severe coronavirus disease 2019 (COVID-19) in patients with no IRD. METHODS: This is a retrospective single-center observational study of patients with IRD actively monitored in the Department of Rheumatology who were hospitalized due to COVID-19. RESULTS: Forty-one (1.8%) out of 2315 patients admitted due to severe SARS-CoV-2 pneumonia suffered from an IRD. The admission OR for patients with IRD was 1.91 against the general population, and it was considerably higher in patients with Sjögren syndrome, vasculitis, and systemic lupus erythematosus. Twenty-seven patients were receiving treatment for IRD with corticosteroids, 23 with conventional DMARDs, 12 with biologics (7 rituximab [RTX], 4 anti-tumor necrosis factor [anti-TNF], and 1 abatacept), and 1 with Janus kinase inhibitors. Ten deaths were registered among patients with IRD. A higher hospitalization rate and a higher number of deaths were observed in patients treated with RTX (OR 12.9) but not in patients treated with anti-TNF (OR 0.9). CONCLUSION: Patients with IRD, especially autoimmune diseases and patients treated with RTX, may be at higher risk of severe pneumonia due to SARS-CoV-2 compared to the general population. More studies are needed to analyze this association further in order to help manage these patients during the pandemic.
