BACKGROUND: Serum anti-single stranded DNA antibody (anti-ssDNAab) is used as a marker for systemic lupus erythematosus. We found a 'prozone-like phenomenon,' which was different from an original prozone phenomenon, in chemiluminescent enzyme immunoassay using magnetic particles for the measurement of serum anti-ssDNAab titers. We investigated mechanisms of the prozone-like phenomenon and countermeasures to prevent it from being overlooked. METHODS: This study examined 679 samples from patients tested for anti-ssDNAab titer at our hospital...

OBJECTIVES: Mortality due to rare diseases, which are substantial sources of premature mortality, is underreported in mortality studies. The objective of this study was to determine the completeness of reporting systemic lupus erythematosus (SLE) as a cause of death. METHODS: In 2017, we linked data on a Swedish population-based cohort (the Swedish Lupus Linkage, 2001-2013) comprising people with SLE (n = 8560) and their matched general population comparators (n = 37 717) to data from the Cause of Death Register...

Pro- and anti-inflammatory effector functions of IgG antibodies (Abs) depend on their subclass and Fc glycosylation pattern. Accumulation of non-galactosylated (agalactosylated; G0) IgG Abs in the serum of rheumatoid arthritis and systemic lupus erythematosus (SLE) patients reflects severity of the diseases. In contrast, sialylated IgG Abs are responsible for anti-inflammatory effects of the intravenous immunoglobulin (pooled human serum IgG from healthy donors), administered in high doses (2 g/kg) to treat autoimmune patients...

The brain and nervous system are important targets for immune-mediated damage in systemic lupus erythematosus (SLE), resulting in a complex spectrum of neurological syndromes. Defining nervous system disease in lupus poses significant challenges. Among the difficulties to be addressed are a diversity of clinical manifestations and a lack of understanding of their mechanistic basis. However, despite these challenges, progress has been made in the identification of pathways which contribute to neurological disease in SLE...

Bullous pemphigoid (BP) is a blistering autoimmune disease mainly observed in elderly patients. Several triggers are known for this autoimmune disease and some drugs are known to be a cause of BP. However, there are only few case reports on the induction of BP under adalimumab therapy. Other autoimmune diseases, such as lupus erythematosus, are also known to occur under TNF inhibition. Here, we report on an 81-year-old patient who received adalimumab for ulcerative colitis and subsequently developed BP. Other causes of BP (tumors, other drugs, viral or toxoplasma infections) were excluded...

An increased risk for Systemic Autoimmune Diseases (SAID) has been reported in Libby, Montana, where extensive exposures to fibrous amphiboles occurred due to mining and use of asbestos-laden vermiculite. In addition, positive antinuclear autoantibody tests are associated with exposure to Libby Asbestiform Amphiboles (LAA) in both humans and mice. Among 6603 subjects who underwent health screening at the Center for Asbestos Related Diseases (CARD, Libby MT), 13.8% were diagnosed with an autoimmune disease, with prevalence values for the most common SAID being significantly higher than expected in the United States...

The American College of Rheumatology (ACR) case definitions for 19 neuropsychiatric syndromes constitute a comprehensive classification of nervous system events in SLE patients. However, additional strategies are needed to determine whether a neurological syndrome is attributable to SLE versus a competing co-morbidity. Cognitive function is a clinical surrogate of overall brain health with applications in both diagnosis and determination of clinical outcomes. Ischemic and inflammatory mechanisms are both key components of the immunopathogenesis of NPSLE, including abnormalities of the blood-brain-barrier and autoantibody mediated production of pro-inflammatory cytokines...

Controlled macrophage differentiation and activation in the initiation and resolution of inflammation is crucial for averting progression to chronic inflammatory and autoimmune diseases. Here we show a negative feedback mechanism for proinflammatory IFN-γ activation of macrophages driven by macrophage-associated matrix metalloproteinase 12 (MMP12). Through C-terminal truncation of IFN-γ at 135Glu↓Leu136 the IFN-γ receptor-binding site was efficiently removed thereby reducing JAK-STAT1 signaling and IFN-γ activation of proinflammatory macrophages...

We report a case of severe lupus myocarditis with rapid, acute deterioration to cardiogenic shock and multiorgan failure, highlighting the importance of early identification and treatment of acute presentations in patients with systemic lupus erythematosus. A 31-year-old woman with previously diagnosed subacute cutaneous lupus erythematosus initially presented with abdominal pain and frank per-rectal bleeding. She deteriorated rapidly with type 1 respiratory failure and acute kidney injury requiring dialysis secondary to acute cardiac failure with a prolonged intensive care unit admission, over a month...

OBJECTIVES: In patients with systemic lupus erythematosus (SLE), immune tolerance breakdown leads to autoantibody production and immune-complex glomerulonephritis. This study aimed to identify pathogenic plasma cells (PC) in the development of lupus nephritis. METHODS: PC subsets in peripheral blood and renal tissue of patients with SLE and lupus mice were examined by flow cytometry and confocal microscopy, respectively. Sorting-purified PCs from lupus mice were adoptively transferred into Rag2 -deficient recipients, in which immune-complex deposition and renal pathology were investigated...

OBJECTIVES: Studies have suggested a possible autoimmune contribution in a subset of patients with schizophrenia. The purpose of this study was to determine if a history of autoimmune diseases (AD) is associated with an increased risk of later onset of schizophrenia. METHODS: Taiwan's National Health Insurance Research Database was used to identify a total of 64,817 AD patients and an equal number of age-matched control patients. The incidence rates of schizophrenia with a maximum follow-up period of 10 years between patients with and without AD were compared using a Cox proportional hazard model to estimate the hazard ratio (HR) and 95% confidence interval (95% CI)...

BACKGROUND: Anti-nuclear antibodies (ANA), anti-extractable nuclear antigens (ENA) and anti-dsDNA antibodies are often associated with cutaneous lupus erythematosus (CLE), with variable frequency depending on skin subtype. However, specific data based on large case-series on the pathogenetic, diagnostic, and prognostic meaning of such autoantibodies are still lacking. OBJECTIVE: To characterize the correlations between CLE subtypes as well as LE-non specific skin lesions and their autoantibody pattern...

Fibrillary glomerulonephritis (FGN) is an uncommon cause of primary glomerular disease. FGN is usually idiopathic; however, it has been associated with underlying malignancy or autoimmune diseases in some patients as well. The most commonly found autoimmune diseases in FGN patients include Graves' disease, systemic lupus nephritis, Chron's disease, and idiopathic thrombocytopenia purpura. FGN in a patient with underlying asymptomatic Sjogren's syndrome is very rare in the literature, with only two previously reported cases of this association...

The pathophysiology of systemic lupus erythematosus (SLE) has been intensely studied but remains incompletely defined. Currently, multiple mechanisms are known to contribute to the development of SLE. These include inadequate clearance of apoptotic debris, aberrant presentation of self nucleic antigens, loss of tolerance, and inappropriate activation of T and B cells. Genetic, hormonal, and environmental influences are also known to play a role. The study of lupus in children, in whom there is presumed to be greater genetic influence, has led to new understandings that are applicable to SLE pathophysiology as a whole...

Introduction: Autoantibodies to cytosolic 5'-nucleotidase 1A (cN-1A; NT5C1A) have a high specificity when differentiating sporadic inclusion body myositis from polymyositis and dermatomyositis. In primary Sjögren's syndrome (pSS) and systemic lupus erythematosus (SLE) anti-cN-1A autoantibodies can be detected as well. However, various frequencies of anti-cN-1A reactivity have been reported in SLE and pSS, which may at least in part be explained by the different assays used. Here, we determined the occurrence of anti-cN-1A reactivity in a large number of patients with pSS and SLE using one standardized ELISA...
