However, overall TNFi use has declined with increasing use of other bDMARDs and tsDMARDs, particularly ustekinumab, secukinumab, and tofacitinib.

Metabolic syndrome was defined according to the National Cholesterol Education Program Adult Treatment Panel III definition. Adipokines were assessed on stored samples from a sub‐sample of responders and non‐responders (N=200). The primary outcome was the achievement of a change as large as the minimal clinically important difference (MCID) for the Clinical Disease Activity Index (CDAI) at 6 months.ResultsAmong 2,368 participants, 687 (29%) had metabolic syndrome. Metabolic syndrome was associated with lower odds of achieving CDAI MCID [OR (95% CI): 0.69 (0.56,0.86) p=0.001] with a dose‐dependent decrease in response rate according to the number of components present. Model fit was superior for metabolic syndrome compared to BMI. Associations between metabolic syndrome and MCID achievement were similar between patients receiving TNFi [OR (95% CI): 0.65 (0.49,0.87) p=0.003] v. non‐TNF therapies [OR (95% CI): 0.76 (0.55,1.04) p=0.08)] (p‐for‐interaction=0.49).

However, the body's largest mucosal compartment, the gut, has not yet been examined. We therefore investigated the presence of several AMPA (antibodies against citrullinated (ACPA), carbamylated (anti‐CarP) and acetylated (AAPA) proteins) at different mucosal sites, including the intestinal tract.MethodsPaired fecal/ileal wash, saliva and serum samples of RA patients and healthy volunteers were collected in two independent cohorts. Data involving feces was replicated in a third cohort. In these secretions AMPA were analyzed using in‐house ELISA with unmodified peptides as control. In fecal samples total IgA and anti‐E. coli IgA were measured.ResultsACPA, anti‐CarP and AAPA IgA were measurable in saliva of seropositive RA patients (prevalence 9‐40%). No AMPA could be detected in feces. IgA was present since total IgA and anti‐E. coli IgA was detectable in feces of ACPA‐positive RA patients and healthy donors. Results were confirmed in another cohort using colonoscopically collected ileal wash samples.ConclusionOur study shows the presence of ACPA, anti‐CarP and AAPA IgA in saliva of ACPA‐seropositive RA patients. However, no AMPA could be detected in feces/ileal wash samples of these patients, although our assays were able to measure other antigen‐specific antibodies. These data suggest that mucosal autoantibody secretion may occur in the oral mucosa of RA patients, while no evidence could be found for this process in the lower gastro‐intestinal tract.","PeriodicalId":129,"journal":{"name":"Arthritis & Rheumatology","volume":"7 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142448671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
