Oxidation of atherogenic low-density lipoproteins (LDL) plays a key role in the pathogenesis of atherosclerosis. Oxidation stress and inflammation are closely interrelated and they can potentiate one another. In the subendothelial space of the arterial intima, monocytes/macrophages become activated and phagocyte oxidized LDL (oxLDL) via scavenger receptors. It has been demonstrated that oxLDL forms complex with plasma β2-glycoprotein I (β2GPI) and becomes autoantigenic triggering synthesis of specific antiphosholipid antibodies...

BACKGROUND: Identifying M-type phospholipase A2 receptor (PLA2R) is a landmark breakthrough for understanding adult idiopathic membranous nephropathy (iMN). However, potential roles for PLA2R in pediatric iMN have not been well investigated. METHODS: A total of 34 pediatric iMN patients who underwent kidney biopsy between 1972 and 2015 were enrolled in this study. The study cohort consisted of 15 children aged from 3 to 9 years and 19 aged from 10 to 15 years...

A 17-year-old female patient affected by systemic lupus erythematosus (SLE) (who had been taking 300 mg/die of hydroxychloroquine for 3 years), Graves' disease (treated with 10 mg/die of tapazole), and celiac disease came to our attention for urticarial vasculitis. She had been taking prednisone (25 mg/die) for 3 days, and her blood tests showed high levels of Mycoplasma pneumoniae IgM and IgG antibodies. The association between urticaria and M. pneumoniae infections can be present in up to 7% of the cases and, to the best of our knowledge, only two reports of urticarial vasculitis and M...

Cardiovascular diseases, as a result of atherosclerosis, are the leading cause of mortality in the world. Atherosclerosis used to be considered as a degenerative impairment of the artery wall. Nevertheless, it is presently rather regarded as an autoimmune process with the involvement of both innate and adaptive immunity. Recently, it was demonstrated that the cardiovascular risk is increased in autoimmune diseases.In the pathogenesis of atherosclerosis in chronic inflammatory diseases both traditional and non-traditional risk factors are important...

Adoptive transfer of regulatory T cells (Tregs) can delay disease progression and reduce mortality in lupus-prone mice. Here, we tested whether complex (IL-2C) consisting of IL-2 and anti-IL-2 monoclonal antibody (JES6-1) ameliorates lupus nephritis by expanding Tregs as an alternative to problematic Treg infusion therapy. IL-2C treatment of NZB/W F1 mice induced an effective and sustained expansion of CD4(+)CD25(+)Foxp3(+) Tregs in both the kidneys and spleen along with decreased renal infiltration of T cells, B cells, and innate immune cells...

OBJECTIVE: Past publications have highlighted an excess rheumatic disease incidence and prevalence in indigenous populations of Canada (First Nations, Inuit, and Métis), and the United States of America (Alaska Native and American Indian). We have updated these reviews and expanded the scope to include New Zealand (Maori) and Australia (Aborigine) indigenous populations. METHODS: We performed a broad search using medical literature databases, indigenous specific online indexes, and government websites to identify publications reporting the incidence and/or prevalence of arthritis conditions (rheumatoid arthritis, spondyloarthropathies, gout, osteoarthritis, systemic autoimmune rheumatic diseases, and juvenile idiopathic arthritis) in the indigenous populations of Canada, America, New Zealand, and Australia...

We evaluated the possible association between FCGR3A V/F (158) polymorphism and SLE susceptibility and clinical phenotype in 305 sequentially retrieved SLE patients and 300 healthy controls from the southeastern part of Brazil by allele-specific polymerase chain reaction. Our results showed no association between FCGR3A 158V/F alleles and susceptibility to SLE in this series of patients albeit the heterozygous genotype was strongly associated with the disease.

BACKGROUND: Only a few biomarkers are available for assessing disease activity in systemic lupus erythematosus (SLE). Mean platelet volume (MPV) has been recently studied as an inflammatory biomarker. It is currently unclear whether MPV may also play a role as a biomarker of disease activity in adult patients with SLE. OBJECTIVE: We investigated the association between MPV and disease activity in adult patients with SLE. METHODS: In this retrospective study, we compared two groups of adult patients divided according to disease activity (36 per group)...

BACKGROUND: Articular manifestations are common in systemic lupus erythematosus (SLE) whereas erosive disease is not. Antibodies to cyclic citrullinated peptide (anti-CCP) are citrulline-dependent in rheumatoid arthritis (RA), whereas the opposite is suggested in SLE, as reactivity with cyclic arginine peptide (CAP) is typically present. Antibodies targeting carbamylated proteins (anti-CarP) may occur in anti-CCP/rheumatoid factor (RF)-negative cases long before clinical onset of RA. We analysed these antibody specificities in sera from European patients with SLE in relation to phenotypes, smoking habits and imaging data...

Systemic lupus erythematosus (SLE) is a prototypical autoimmune disease characterized by multiorgan inflammation induced by autoantibodies. Early growth response gene 2 (Egr2), a transcription factor essential for T-cell anergy induction, controls systemic autoimmunity in mice and humans. We have previously identified a subpopulation of CD4(+) regulatory T cells, CD4(+)CD25(-)LAG3(+) cells, that characteristically express both Egr2 and LAG3 and control mice model of lupus via TGF-β3 production. However, due to the mild phenotype of lymphocyte-specific Egr2-deficient mice, the presence of an additional regulator has been speculated...

BACKGROUND: Systemic lupus erythematosus (SLE) is an autoimmune disease marked by the disruption of the immune homeostasis. Patients exhibit a wide range of clinical manifestations, and environmental and genetic factors are involved in SLE pathogenesis. Evidence suggests that abnormalities in the cellular and molecular events that coordinate apoptosis may favour the generation of autoantigens involved in autoimmunity. In this way, the apoptotic deregulation may be affected by polymorphic variants in apoptotic-related genes...

Cell-free DNA (cfDNA) represents a small fraction of total DNA pool that circulates freely in the blood both in normal and pathological conditions. Data indicate that cfDNA plays an important role in the pathogenesis of systemic lupus erythematosus (SLE) and hypomethylation may be crucial for its immunogenic properties. Although differences in quantification methodology hinder the comparison of results between the studies, it appears that levels of cfDNA are abnormally elevated in SLE patients and correlate with various antibody titers, but not with disease activity...

BACKGROUND: Systemic lupus erythematosus (SLE) is a multi-system, complex disease in which the environment interacts with inherited genes to produce broad phenotypes with inter-individual variability. Of 46 single nucleotide polymorphisms (SNPs) shown to confer genetic risk for SLE in recent genome-wide association studies, 30 lie within noncoding regions of the human genome. We therefore sought to identify and describe the functional elements (aside from genes) located within these regions of interest...

Complex rheumatological syndromes such as Systemic lupus erythematosus, Sjogren's Syndrome and many connective tissue disorders can be a challenge to classify and diagnose, due to their wide-ranging signs and symptoms, not all of which will necessarily be present in all patients. This can result in difficulties for the clinician, patient and researcher if signs and symptoms are either overlooked or are incorrectly included in the nosology or classification of diseases. This article presents a formalism-based approach to describing syndromes...

A 31-year old woman with persistent fever for 6 weeks and unresponsive to antibiotic therapy came for rheumatologic investigation. After computed tomography (CT) studies of her neck, thorax and abdomen revealed bilateral cervical, axillary and retroperitoneal lymph node enlargements, histopathologic evaluation of the resected nodes showed features of histiocytic necrotizing lymphadenopathy suggestive of Kikuchi-Fujimoto's lymphadenopathy. Kikuchi-Fujimoto Disease (KFD) involving the retroperitoneal nodes is extremely unusual and even more challenging to diagnose when there are no early signs of extranodal involvement or abdominopelvic pain...
