Multiple studies have found a relationship between alcohol consumption and disease activity in rheumatoid arthritis (RA), although reverse causation has been suggested to explain the association. We aimed to study the relationship between alcohol consumption and disease activity, disease progression, and health-related quality of life in patients with RA.

To assess the efficacy and safety of ABBV-3373, a novel antibody–drug conjugate (ADC) composed of the anti–tumor necrosis factor (anti-TNF) monoclonal antibody adalimumab linked to a glucocorticoid receptor modulator (GRM), compared to adalimumab, in patients with rheumatoid arthritis (RA).

Mitochondria are found in the extracellular space in rheumatoid arthritis (RA). However, whether mitochondria are a source of autoantigens in RA has not been carefully addressed. Thus, we undertook this study to investigate the presence and significance of antimitochondrial antibodies (AMAs) in patients with RA.

Over 100 DNA variants have been associated with osteoarthritis (OA), including rs1046934, located within a linkage disequilibrium block encompassing part of COLGALT2 and TSEN15. The present study was undertaken to determine the target gene(s) and the mechanism of action of the OA locus using human fetal cartilage, cartilage from OA and femoral neck fracture arthroplasty patients, and a chondrocyte cell model.

Variants in STAT4 are associated with systemic lupus erythematosus (SLE) and other autoimmune diseases. We undertook this study to investigate how disease-associated variants affect STAT4 expression, in particular in CD4+ T cells where STAT4 plays an essential role.

B cell hyperactivity plays an important role in primary Sjögren's syndrome (SS). We undertook this study to better understand the B cell effector branch, namely antibody-secreting cells (ASCs) in primary SS, and to examine the quantity, maturity, and inflammatory properties of ASCs in primary SS patients.

The present study was undertaken to longitudinally evaluate titers of antibodies against β2-glycoprotein I (anti-β2GPI) and domain 1 (anti-D1), to identify predictors of variations in anti-β2GPI and anti-D1 titers, and to clarify whether antibody titer fluctuations predict thrombosis in a large international cohort of patients who were persistently positive for antiphospholipid antibodies (aPL) in the APS ACTION Registry.

Systemic sclerosis (SSc) is a complex autoimmune disease with a strong genetic component. However, most of the genes associated with the disease are still unknown because associated variants affect mostly noncoding intergenic elements of the genome. We used functional genomics to translate the genetic findings into a better understanding of the disease.

Gout flares that occur during urate-lowering therapy (ULT) are typically related to the shrinkage of tophi due to aggregated neutrophil extracellular traps (NETs) that have captured monosodium urate crystals in the tissues. The present study was undertaken to analyze the blocking effect of α1-antitrypsin on neutrophil elastase, and it was found that α1-antitrypsin induced rapid inflammation in the presence of unstable tophi.

Antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV) is a rare, life-threatening inflammation of blood vessels that can affect both adults and children. Compared to adult-onset disease, AAV is especially rare in children, with an annual prevalence of 0.5–6.4 cases per million children.

Increased Toll-like receptor 7 (TLR-7) signaling leading to the production of type I interferon (IFN) is an important contributor to human systemic lupus erythematosus (SLE). Protein kinase C and casein kinase substrate in neurons 1 (PACSIN1), a molecule that regulates synaptic vesicle recycling, has been linked to TLR-7/TLR-9–mediated type I IFN production in humans and mice, but the underlying mechanism is unknown.
