Consequently, the pivotal strategy in preventing joint damage and fostering functional recovery lies in the effective management of synovial inflammation. Disease-modifying antirheumatic drugs (DMARDs) and prednisone therapy remain the first-line treatments for RA. However, in instances of refractory RA, these medications may fall short in adequately controlling inflammation, and they are often accompanied by several adverse effects, including limited bioavailability, therapeutic resistance, and potentially toxic side effects. Given these challenges, the identification of targeted therapies to manage disease activity and diminish inflammation becomes imperative.Recently, biologic agents for the treatment of RA have garnered significant attention owing to their minimal side effect profile, reduced potential for drug dependence, and their precise therapeutic action directly on target cells. This review provides a comprehensive exploration of advancements in biologics that target and inhibit inflammatory cytokine receptors, specifically TNF-α, IL-6, and IL-1β, as well as B lymphocyte receptors, TLR4, nanodrugs, and Janus kinase (JAK) inhibitors in the context of RA.

The aim of our study was to determine the serological status of potential kidney recipients and donors in order to assess the risk of post-transplant CMV infection and disease.</p><p><strong>Patients and methods: </strong>We included 135 and 200 potential kidney transplant donors and recipients, respectively, who were tested for anti-CMV IgM and IgG by chemiluminescence on IMMULITE 2000 XPI®.</p><p><strong>Results: </strong>The prevalence of anti-CMV IgG was 95.50 % (95 % CI [92.63 %-98.37 %]) in hemodialysis patients and 96.30 % (95 % CI [93.12 %-99.48 %]) in potential kidney donors. The difference between the two groups was not significant (p = 0.721). Anti-CMV IgM were only detected in the sera of 13 hemodialysis patients and 3 healthy subjects. In both groups, the highest rate of anti-CMV IgG positivity was observed in subjects aged over 50 years (100 %), followed by those aged between 18 and 30 years old, with a slightly higher seroprevalence in men than in women.</p><p><strong>Conclusion: </strong>Our results suggest a high prevalence of anti-CMV IgG in potential kidney donors and recipients (D+/R+), who could be classified as an intermediate risk group for post-transplant CMV infection and/or disease.</p>","PeriodicalId":23304,"journal":{"name":"Transplant immunology","volume":" ","pages":"102168"},"PeriodicalIF":1.6,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142882882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
