Inflammation, an innate immune response that prevents cellular damage caused by pathogens, consists of two successive mechanisms, namely priming and triggering. While priming is an inflammation-preparation step, triggering is an inflammation-activation step, and the central feature of triggering is the activation of inflammasomes and intracellular inflammatory protein complexes. Flavonoids are natural phenolic compounds predominantly present in plants, fruits, and vegetables and are known to possess strong anti-inflammatory activities. The anti-inflammatory activity of flavonoids has long been demonstrated, with the main focus on the priming mechanisms, while increasing numbers of recent studies have redirected the research focus on the triggering step, and studies have reported that flavonoids inhibit inflammatory responses and diseases by targeting inflammasome activation. Rheumatic diseases are systemic inflammatory and autoimmune diseases that primarily affect joints and connective tissues, and they are associated with numerous deleterious effects. Here, we discuss the emerging literature on the ameliorative role of flavonoids targeting inflammasome activation in inflammatory rheumatic diseases.

Background:Patients with inflammatory rheumatic diseases (IRD) infected with SARS-CoV-2 may be at risk to develop a severe course of COVID-19 due to the immune dysregulation or the influence of immunomodulating drugs on the course of the infection. For a better understanding of SARS-CoV-2 infections in patients with IRD and due to the high incidence of COVID-19 in Madrid from the beginning of this pandemic infection in Spain, the Society of Rheumatology from Madrid (SORCOM) established a registry (REUMA-COVID SORCOM) shortly after the beginning of the pandemic in Spain.Objectives:To determine factors associated with severity of infection with SARS-CoV-2 in patients with inflammatory rheumatic diseases in MadridMethods:The REUMA-COVID SORCOM registry is a multicenter, retrospective, observational cohort study conducted in Madrid, a SORCOM initiative. All rheumatology departments from Madrid were invited to participate. The study includes patients with IRD presenting with a confirmed or highly suspected diagnosis of COVID-19 between March 1, 2020, and November 10, 2020. We consider severe infection death or need of hospitalization. Inclusion criteria was having an IRD and at least 1 of the following 4 criteria: (1) a biologically confirmed COVID-19 diagnosis based on a positive result of a SARS-CoV-2 polymerase chain reaction (PCR) test on a nasopharyngeal swab; (2) Detection of IgM or IgG anti SARS-CoV2 in a symptomatic or asymptomatic patients (3)typical thoracic computed tomography (CT) abnormalities (ground-glass opacities) in epidemic areas; (4) COVID19–typical symptoms in an epidemic zone of COVID-19.Results:As of November 10, 2020, 417 patients with IRD were included in the REUMA-COVID SORCOM registry. 5 patients were discharged for incomplete data. Of 412 patients (mean age 57 years, 87.4% Caucasian race, 66.3% female) 174 need hospitalization (42.2%) and 33 patients died (18.4% mortality in hospitalized patients). 82.3% had comorbidities. 234 (56.8%) patients were classified as inflammatory arthropathy, 133 (32.3%) had connective tissue diseases (CTD). 41.1% of the patients had a large history of IRD (> 10 years). 10.4% of patients had previously pulmonary involvement. The study includes 143 patients taking Methotrexate, 89 patients taking anti-TNFα therapy and 27 Rituximab. In the univariant analysis, no differences were seen in the severity of COVID-19 infection in patients taking methotrexate. 63% of the all patients taking Rituximab included in the registry need hospitalization and 22% of them died. Hypertension, COPD or cardiovascular disease was associated with hospitalization.Independent factors associated with COVID-19 hospitalization in the multivariate analysis was: age (>62 years), male sex, IMC >30, previous cardiovascular comorbidities and the IRD disease duration (> 10 years). Independent factors associated with COVID-19 related death was: age (> 62 years), having a CTD diagnose, pulmonary involvement before infection and chronical GC treatment.Conclusion:Patients with IRD represent a population of particular interest in the pandemic context because the baseline immunological alteration and the treated with immunosuppressants agents they receive, comorbidities and the well-known risk of severe infection. Older age, male sex, cardiovascular comorbidities were factors associated with high risk of hospitalization in IRD patients. CTD diseases, previously pulmonary involvement and chronical GC treatment with more than 10mg/day were associated with high risk of death. Neither anti TNF-α treatment nor Methotrexate were risk factor for hospitalization or death COVID-19 related in IRD patients.Disclosure of Interests:None declared

Background:The development of biologics for the treatment of systemic rheumatic diseases increased the risk of infections. The management of this complication deserves particular attention since it remains a major cause of morbidity and mortality.Objectives:The aim of our study was to determine infection frequency under biological treatment and consequences on the therapeutic management.Methods:Patients included in the Biological National Registry (BINAR) from 2016 to 2020. Data related to the disease, biological agents, and infections occurring under biologic disease-modifying antirheumatic drugs (bDMARDs) were collected.Results:The study included 298 patients with a mean age of 49.2 years [18-79] 175 patients with rheumatoid arthritis and 123 with spondyloarthritis (Axial Spondyloarthritis=48, Enteropathic Arthritis=41, Psoriatic Arthritis=34). Anti Tumor necrosis factor-alpha (Anti-TNF) agents were the most prescribed bDMARDs in 87.9% (n=263) of patients: Infliximab 20.4% (n=61),Etanercept 23.1%(n=69), Adalimumab 24.6%(n=74) and Certolizumab (n=79). No patients were treated with Golimumab. Tocilizumab and Rituximab were prescribed respectively in 10.4% (n=31) and 5% (n=15) of patients. Infections occured in 9 patients (3.1%) with a total of 13 infectious episodes 12 bacterial and a viral one. The site of infections was: respiratory (38%), urinary (15%), cutaneous (23%), ORL (8%), infective endocarditis (8%), and other (8%). The infectious agent was identified in only 3 patients. The outcomes were favorable in most cases except in one patient where there was a definitive interruption of bDMARDs. The patient was hospitalized for sepsis complicating a cutaneous infection with favorable outcomes under antibiotics within a week. The biological agent with higher risk of infections was Tocilizumab (p = 0.056), unlike Rituximab (p = 0.483) and Anti-TNF (p = 0.082). All patients who had an infectious episode were under corticosteroids.Conclusion:Our results confirm that bDMARDs are predisposing to infections, but data from BINAR showed that most infections were trivial with no serious outcomes. Therefore, infections should be assessed in patients under bDMARDs for an early therapeutic intervention.Disclosure of Interests:None declared.
