A retrospective study found serum interleukin 6 levels at the onset of IgG4-RD may significantly correlate with clinical inflammatory parameters and the involvement of the bile duct, liver and spleen…
New ACR/EULAR IgG4 Classification Criteria Introduced
Immunoglobulin G4-related disease (IgG4-RD) can cause fibroinflammatory lesions in nearly any organ. Correlation among clinical, serologic, radiologic and pathologic data is required for diagnosis. ACR/EULAR classification criteria for IgG4-RD have now been developed and validated in a large cohort of patients…
Draft Classification Criteria for IgG4-Related Disease Introduced
CHICAGO—John H. Stone, MD, MPH, director of clinical rheumatology at Massachusetts General Hospital, Boston, took the stage at the 2018 ACR/ARHP Annual Meeting to present, for the first time, a draft of new classification criteria for IgG4-related disease (IgG4-RD), a project supported by both the ACR and EULAR. Even though it was the last day…
IgG4-Related Kidney Disease: Diagnostics, Manifestations & More
Immunoglobin G4-related disease (IgG4-RD) is a rare fibro-inflammatory disease of unknown etiology that has been recently recognized. It can cause fibro-inflammatory masses in almost every organ of the body and is associated with dense lymphoplasmacytic infiltration of IgG4-postitive plasma cells, storiform fibrosis and elevated levels of serum IgG4.1 IgG4-RD is a systemic disease that may…
Gene Signatures in IgG4-Related Disease
Research suggests prednisone treatment can selectively modulate the signatures of regulatory T (Treg) cells, eosinophils and neutrophils in patients with IgG4-related disease. The results show IgG4-related disease may result from an imbalance of immune and inflammatory cells…
International Consensus Statement on the Management & Treatment of IgG4-Related Disease
IgG4-related disease (IgG4-RD) is an immune-mediated fibro-inflammatory condition that affects multiple organs and can lead to tumefactive, tissue-destructive lesions and organ failure. An international panel of experts has released a consensus statement on its management…
