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 β2-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. Emerging evidence positions the liver as a crucial interface that links immune regulation, metabolism and autoimmunity. This Review explores the associations between hepatic dysfunction and autoimmune rheumatic diseases, highlighting implications for pathogenesis, clinical manifestations and treatment.","PeriodicalId":18810,"journal":{"name":"Nature Reviews Rheumatology","volume":"22 11","pages":"675-695"},"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}

Childhood-onset IgAV is a common disease and usually follows a self-limiting course, whereas adult-onset IgAV is considerably less frequent and is associated with a poorer prognosis. The diagnosis, assessment and management of adult-onset IgAV remain challenging owing to the absence of validated diagnostic criteria for adults and lack of IgAV-specific standardized disease activity scores. Short-term outcomes are mainly determined by gastrointestinal complications, whereas kidney involvement and the risk of progression to chronic kidney disease are the major determinants of long-term prognosis. The treatment of adult-onset IgAV is limited by the paucity of high-quality clinical trials and standardized therapeutic approaches. Here, we present evidence-based, multidisciplinary guidelines for the diagnosis and management of adult-onset IgAV that reflect advances in understanding of pathogenesis, differential diagnoses and treatment over the past two decades. Developed by a panel of leading European experts on the basis of systematic literature review and expert opinion, these guidelines comprise 14 recommendation statements and overarching principles that provide a structured and pragmatic clinical framework for the diagnosis, treatment and follow-up of adult-onset IgAV. These evidence-based guidelines provide recommendations for the diagnosis and management of adult-onset IgA vasculitis. Current evidence regarding clinical manifestations, diagnostic investigations, prognostic factors and therapeutic approaches is reviewed, with practical algorithms to support evidence-based clinical practice.","PeriodicalId":18810,"journal":{"name":"Nature Reviews Rheumatology","volume":"22 10","pages":"643-662"},"PeriodicalIF":33.7,"publicationDate":"2026-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41584-026-01420-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148795364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The management of newly diagnosed EGPA still relies on therapeutic strategies that were initially validated for other forms of anti-neutrophil cytoplasmic antibody-associated vasculitis, including microscopic polyangiitis and granulomatosis with polyangiitis. Whereas the long-term prognosis of microscopic polyangiitis and granulomatosis with polyangiitis depends primarily on controlling initial organ involvement and preventing relapses, EGPA is distinguished by chronic involvement of both upper and lower respiratory airways, which often necessitates prolonged glucocorticoid therapy. Data from clinical trials suggest that targeting the IL-5 pathway with mepolizumab or benralizumab can effectively control persistent respiratory symptoms and reduce the need for glucocorticoids, yet the role of these agents in the management of EGPA at the time of diagnosis and in the long term remains to be defined. Emerging retrospective data on therapies targeting other type 2 cytokines (such as IL-4, IL-13 and thymic stromal lymphopoietin) suggest potential benefits for relapsing respiratory symptoms; however, prospective evidence remains limited and safety has yet to be established. This Review discusses the role of these new targeted therapies in the management of EGPA, alongside historical treatments. The development of targeted therapeutics has transformed the management of eosinophilic granulomatosis with polyangiitis (EGPA). This Review explores the role of these new therapies, as well as that of the still-relevant historical treatments, for the induction and maintenance of remission in EGPA.","PeriodicalId":18810,"journal":{"name":"Nature Reviews Rheumatology","volume":"22 9","pages":"541-557"},"PeriodicalIF":33.7,"publicationDate":"2026-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148673985","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}
