Age-related immunosenescence further increases this susceptibility in older patients. The SARS-CoV-2 (COVID-19) pandemic and measles outbreaks have underscored the importance of optimizing vaccination strategies and improving adherence to recommendations. Nevertheless, coverage for routinely recommended vaccines, including influenza and pneumococcal vaccines, remains suboptimal in this population. Vaccine hesitancy is an important barrier driven by concerns regarding safety, tolerability, disease flares and the potential induction of new autoimmune phenomena. Advanced therapies - including B cell-depleting agents, chimeric antigen receptor T cell therapy and bispecific T cell engagers - can substantially impair vaccine-induced immune responses, highlighting the importance of optimizing vaccination timing in relation to treatment. Although most studies focus on humoral and cellular immune responses, evidence on the long-term durability of vaccine-induced immunity, the need for booster doses and real-world vaccine effectiveness in patients with ARDs remains limited. Ethical considerations are important. Although vaccination in adults is generally not mandatory, improving vaccine uptake reduces the burden of infections in patients with ARDs, contributes to herd immunity and provides indirect protection for other vulnerable populations.</p>","PeriodicalId":18810,"journal":{"name":"Nature Reviews Rheumatology","volume":" ","pages":""},"PeriodicalIF":33.7,"publicationDate":"2026-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148888020","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}

The liver, a central metabolic and immunological organ, has a key role in initiating and amplifying systemic autoimmunity and organ damage. It functions as an interface between the gut microbiome, nutrients, drugs and environmental toxins. The liver regulates immune cell development, coordinates systemic immune responses through metabolite and cytokine production and modifies self-antigens via oxidation, glycosylation and lipidation. These changes can transform normal molecules into autoantigens. Hepatocytes also produce coagulation, complement factors and apolipoproteins, such as β<sub>2</sub>-glycoprotein I, a major target of antiphospholipid antibodies. In addition, the liver secretes antioxidants such as glutathione, albumin and paraoxonase-1, which protect lipoproteins from becoming antigenic and reduce risks of atherosclerosis and thrombosis. Liver diseases such as steatosis and steatohepatitis have bidirectional relationships with systemic lupus erythematosus, antiphospholipid syndrome and other rheumatic conditions. Liver cells can also be direct targets of autoimmune responses. Delineating the role of the liver in metabolic control of autoimmunity and inflammation can lead to better understanding of disease pathogenesis, improved clinical diagnosis and identification of new therapeutic targets in rheumatic diseases.</p>","PeriodicalId":18810,"journal":{"name":"Nature Reviews Rheumatology","volume":" ","pages":""},"PeriodicalIF":33.7,"publicationDate":"2026-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148830454","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}
