Rheumatoid arthritis (RA) is preceded by an at-risk stage of disease that can be marked by the presence of anticitrullinated protein antibodies (ACPAs) but the absence of clinically apparent synovitis (clinical RA). Preemptive intervention in at-risk individuals could prevent or delay future tissue damage; however, the immunobiology of this stage is unclear. Using integrative multiomics,… Continue reading Progression to #rheumatoid arthritis in at-risk individuals is defined by systemic #inflammation and by T and B cell dysregulation

Dynamics of the gut #microbiome in individuals at risk of #rheumatoid arthritis: a cross-sectional and longitudinal observational study
Objectives This work aimed to resolve the conflicting reports on Prevotellaceae abundance in the development of rheumatoid arthritis (RA) and to observe structural, functional and temporal changes in the gut microbiome in RA progressors versus non-progressors.Methods Individuals at risk of RA were defined by the presence of anticyclic citrullinated protein (anti-CCP) antibodies and new musculoskeletal… Continue reading Dynamics of the gut #microbiome in individuals at risk of #rheumatoid arthritis: a cross-sectional and longitudinal observational study
Polycyclic aromatic hydrocarbons and risk of rheumatoid arthritis: a cross-sectional analysis of the National Health and Nutrition Examination Survey, 2007–2016
AbstractObjective While there are several well-established environmental risk factors for rheumatoid arthritis (RA), a paucity of evidence exists linking environmental toxicants with RA prevalence. We aimed to examine the associations between various environmental toxicants and RA among adults in the U.S. general population while adjusting for non-heritable risk factors.Design Cross-sectional study.Setting National Health and Nutrition Examination Survey conducted… Continue reading Polycyclic aromatic hydrocarbons and risk of rheumatoid arthritis: a cross-sectional analysis of the National Health and Nutrition Examination Survey, 2007–2016
Oral mucosal breaks trigger anti-citrullinated bacterial and human protein antibody responses in rheumatoid arthritis
Periodontal disease is more common in individuals with rheumatoid arthritis (RA) who have detectable anti-citrullinated protein antibodies (ACPAs), implicating oral mucosal inflammation in RA pathogenesis. Here, we performed paired analysis of human and bacterial transcriptomics in longitudinal blood samples from RA patients. We found that patients with RA and periodontal disease experienced repeated oral bacteremias… Continue reading Oral mucosal breaks trigger anti-citrullinated bacterial and human protein antibody responses in rheumatoid arthritis
#Intestinal barrier dysfunction plays an integral role in #arthritis pathology and can be targeted to ameliorate disease
HighlightsSerum gut-permeability markers LPB, LPS, and I-FABP are increased in RAMice with arthritis have increased gut permeability and intestinal inflammationBoth bacteria and leukocytes are needed to disrupt gut-barrier integrityPrevention of gut-barrier dysfunction in arthritis ameliorates joint inflammation Context and significanceRheumatoid arthritis is an autoimmune disorder characterized by chronic joint inflammation. Accumulating evidence suggests that changes… Continue reading #Intestinal barrier dysfunction plays an integral role in #arthritis pathology and can be targeted to ameliorate disease
OP0012 ASSOCIATION BETWEEN PASSIVE #SMOKING IN CHILDHOOD AND ADULTHOOD, AND #RHEUMATOID ARTHRITIS: RESULTS FROM THE FRENCH E3N-EPIC COHORT STUDY
Rheumatoid arthritis (RA) is a systemic autoimmune disease of multifactorial aetiology, which preferentially affects women. To date, active smoking has been the most reproducibly reported risk factor for anti-citrullinated protein antibodies (ACPA) positive RA, particularly persons who carry the HLA-DRB1-shared epitope (SE) alleles. Objectives: We aimed to investigate the relationships between passive smoking in childhood… Continue reading OP0012 ASSOCIATION BETWEEN PASSIVE #SMOKING IN CHILDHOOD AND ADULTHOOD, AND #RHEUMATOID ARTHRITIS: RESULTS FROM THE FRENCH E3N-EPIC COHORT STUDY
The oral #microbiome in early #rheumatoid arthritis patients and individuals at risk differs from healthy controls
It has been suggested that rheumatoid arthritis (RA) may originate at the oral mucosa. Our aim was to assess the oral microbiome and the periodontal condition in patients with early rheumatoid arthritis (ERA) and individuals at risk of RA. MethodsThree groups were recruited (50 participants each): (1) ERA patients (2010 ACR/EULAR criteria), (2) at‐risk individuals… Continue reading The oral #microbiome in early #rheumatoid arthritis patients and individuals at risk differs from healthy controls
#Pain and fatigue are longitudinally and bi-directionally associated with more #sedentary time and less standing time in #rheumatoid arthritis
The aims of this study were to examine the longitudinal and bi-directional associations of pain and fatigue with sedentary, standing and stepping time in RA. Methods People living with RA undertook identical assessments at baseline (T1, n = 104) and 6-month follow-up (T2, n = 54). Participants completed physical measures (e.g. height, weight, BMI) and routine clinical assessments to… Continue reading #Pain and fatigue are longitudinally and bi-directionally associated with more #sedentary time and less standing time in #rheumatoid arthritis
Finger Joint #Cartilage Evaluated by Semiquantitative #Ultrasound Score in Patients With #Rheumatoid Arthritis
Joint destruction in rheumatoid arthritis (RA) includes both bone and cartilage lesions. Since joint space narrowing (JSN) is not a direct evaluation of cartilage using radiography, we aimed to examine the validity of ultrasound (US) cartilage evaluation using a semiquantitative method in patients with RA. Methods We enrolled 103 patients with RA who were in… Continue reading Finger Joint #Cartilage Evaluated by Semiquantitative #Ultrasound Score in Patients With #Rheumatoid Arthritis
