Immune Complexes Shape the Pathogenicity of Autoantibodies in Systemic Autoimmune Diseases: Insights From an FcγRIIIA‐Reporter Assay

open access: yesArthritis &Rheumatology, EarlyView.
Objective Immune complexes (ICs), formed by autoantigen and autoantibody, play a pathogenic role in systemic autoimmune diseases through stimulation of Fcγ receptors (FcγR). However, studies investigating bioactivity of circulating ICs across various diseases remain limited.

Kidney Hematopoietic Stem and Progenitor Cells Contribute to Myeloid Development and Pathology in Lupus Nephritis

open access: yesArthritis &Rheumatology, EarlyView.
Objective The hematopoietic system maintains homeostasis by balancing myeloid and lymphoid cell production in the bone marrow (BM). In response to increased hematopoietic demand, extramedullary hematopoiesis (EMH) may occur in nonlymphoid organs. We investigated the role of EMH and kidney‐resident hematopoietic stem and progenitor cells (HSPCs) in ...

Higher Complement C4 Gene Copy Number Constitutes a Shared Genetic Risk Factor for Giant Cell Arteritis and IgA Vasculitis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...

The American College of Rheumatology Updated Recommended Methods for Development of Disease Classification and Response Criteria

open access: yesArthritis &Rheumatology, EarlyView.
Disease classification criteria and response criteria are important tools in the conduct of observational studies and clinical trials for rheumatic diseases. This paper updates methodologic guidance for classification and response criteria funded, developed and/or endorsed by the American College of Rheumatology (ACR), incorporating contemporary ...

Increased Risk of Intrahepatic Cholestasis of Pregnancy in Women With Systemic Lupus Erythematosus Exposed to Azathioprine

open access: yesArthritis &Rheumatology, EarlyView.
Objective To evaluate the risk of intrahepatic cholestasis of pregnancy (ICP) in azathioprine (AZA)–exposed versus unexposed systemic lupus erythematosus (SLE) pregnancies within the multicenter prospective Lupus in Pregnancy (LEGACY) cohort. Methods LEGACY is conducted at Systemic Lupus International Collaborating Clinics in Canada, South Korea, Peru,

T Cell Plasticity in Systemic Lupus Erythematosus Revealed by Large‐Scale T Cell Receptor Repertoire and Transcriptome Studies

open access: yesArthritis &Rheumatology, EarlyView.
Objective We aimed to characterize CD4+ T cell plasticity in human systemic lupus erythematosus (SLE) by leveraging T cell receptor (TCR) repertoire features as markers of prior lineage states, integrating TCR and transcriptomic profiling to delineate plasticity patterns and evaluate their association with clinical disease activity. Methods We used TCR
