Systemic lupus erythematosus (SLE) is a complex disease with different genetic, immunologic, and environmental factors contributing to the pathogenesis. Monogenic SLE could help us understand the main phases of immune dysregulation in SLE. The aim of this review is to summarize the current knowledge on monogenic SLE with the implications of the respective genes on disease pathogenesis. A comprehensive literature search on monogenic SLE was conducted utilizing the Cochrane Library and MEDLINE/PubMed databases...

OBJECTIVE: Until now, concomitant neurological manifestations and positive antiphospholipid antibodies (APA(s)) have been investigated in different manners. The most important conflicts in this field are whether those manifestations are directly related to APA(s) or not and treatment strategies. METHOD: In this study, adopting a different manner, we selected patients with a recently defined neurological problem (according to study protocol) and positive APA without any other risk factor, to compare types, amounts, and titer of APAs...

Coronary flow reserve (CFR), a measure of both obstructive coronary artery disease and microvascular dysfunction, has been evaluated in systemic rheumatic diseases (RDs), but a comprehensive critical appraisal of the available evidence is lacking. The objective of this study is to conduct a systematic review and meta-analysis of studies with small sample size investigating the associations between the presence of RDs and CFR to increase statistical power and accuracy. PubMed, Web of Science, Scopus, and Google Scholar, from inception to March 2018, were searched for studies reporting on CFR in RDs in comparison to healthy subjects...

OBJECTIVE: Upregulation of type I interferons (IFN-I) is a hallmark of systemic autoimmune diseases like primary Sjögren's syndrome (pSS), systemic lupus erythematosus (SLE) and systemic sclerosis (SSc). Expression of IFN-I is induced by three different receptor families: Toll-like receptors (TLRs), RIG-like receptors (RLRs) and DNA-sensing receptors (DSRs). TANK-binding kinase (TBK1) is an important signaling hub downstream of RLRs and DSRs. TBK1 activates IRF3 and IRF7, leading to IFN-I production and subsequent induction of interferon stimulated genes (ISGs)...

BACKGROUND: Pregnant women with systemic lupus erythematosus (SLE) have increased risk of adverse outcomes including disease flare, spontaneous abortion, preeclampsia/eclampsia, premature birth and maternal death. However, pregnancy outcomes among adolescents and young women with SLE have not been well-explored. Our objective was to compare risk of adverse pregnancy outcomes in adolescents and young women with SLE to risk among peers without SLE. METHODS: We studied the 2000-2011 Nationwide Inpatient Sample (NIS) of the Healthcare Cost and Utilization Project (HCUP) to estimate the prevalence of adverse pregnancy outcomes in women with SLE aged ≤ 21 years at time of delivery...

Myasthenia gravis (MG) is a rare autoimmune disease of the neuromuscular junction. It is characterized by variable weakness and excessive fatigability of skeletal muscles. In the last few years, numerous reports have been published showing the association between autoimmune diseases, such as systemic erythematous lupus or rheumatoid arthritis, with lymphoid neoplasias. The association between MG and lymphoid neoplasia seems to be less frequent. To analyze this association we reviewed the MG patients in the Department of Neurology, Hospital Salvador of Santiago, Chile...

Measurement of type I interferon (IFN-I) has potential to diagnose and stratify autoimmune diseases, but existing results have been inconsistent. Interferon-stimulated-gene (ISG) based methods may be affected by the modularity of the ISG transcriptome, cell-specific expression, response to IFN-subtypes and bimodality of expression. We developed and clinically validated a 2-score system (IFN-Score-A and -B) using Factor Analysis of 31 ISGs measured by TaqMan selected from 3-IFN-annotated modules. We evaluated these scores using in-vitro IFN stimulation as well as in sorted cells then clinically validated in a cohort of 328 autoimmune disease patients and healthy controls...

OBJECTIVE: Determination of lupus anticoagulants (LA) is an important, but still challenging test in the diagnosis of antiphospholipid syndrome (APS). This is especially the case in patients using one of the direct oral anticoagulants (DOACs). The aim of our study was to examine the influence of these drugs on DRVVT assays from two companies (in each case: screening test, confirming test and calculated ratio) and on aPTT and lupus-sensitive aPTT. METHODS: We used plasma samples from healthy volunteers spiked with the DOACs dabigatran, rivaroxaban and apixaban (0, 10, 30, 50, 100 ng/mL) for testing...

OBJECTIVES: The diagnostic tests for autoimmune disease include screening for autoantibodies for nuclear antigens (ANA) and antibodies against extractable nuclear antigens (ENA). Using the line immunoassay (LIA) method, various kinds of ENA antibodies can be detected simultaneously. We evaluated the performance of the newly launched LIA-ANA-Profile-17S (Shenzhen YHLO Biotech, Shenzhen, China) as compared to a conventional LIA kit. METHODS: Residual samples were collected from 200 patients who had been tested for ANA using indirect immunofluorescence...

This study was designed to define gene expression and H3K4me3 histone modifications in T cells, B cells, and monocytes in systemic lupus erythematosus (SLE). Array studies of total peripheral blood mononuclear cells have demonstrated gene expression signatures related to neutrophils, interferon, and other inflammatory pathways. It is not clear how consistent these effects are across different cell types. In this study, RNA-seq and chromatin immunoprecipitation-seq were utilized to identify gene expression patterns and H3K4me3 histone modifications related to promoter activation in SLE...

Several studies reported that autoimmune diseases share a number of susceptibility genes. Of these genes, a SNP rs7708392 in TNIP1 was reported to be associated with systemic lupus erythematosus (SLE). Autoimmune hepatitis (AIH), a rare chronic progressive liver disease, shares some clinical features with SLE. Therefore, we investigated whether the SNP is associated with Japanese AIH. An association study of rs7708392 was conducted in 343 Japanese AIH patients and 828 controls. We found that rs7708392 is associated with AIH (P = 0...

The type I interferon pathway has been implicated in the pathogenesis of a number of rheumatic diseases, including systemic lupus erythematosus, Sjögren syndrome, myositis, systemic sclerosis, and rheumatoid arthritis. In normal immune responses, type I interferons have a critical role in the defence against viruses, yet in many rheumatic diseases, large subgroups of patients demonstrate persistent activation of the type I interferon pathway. Genetic variations in type I interferon-related genes are risk factors for some rheumatic diseases, and can explain some of the heterogeneity in type I interferon responses seen between patients within a given disease...

STING is a core adaptor in innate nucleic acid sensing in mammalian cells, on which different sensing pathways converge to induce type I interferon (IFN) production. Particularly, STING is activated by 2'3'-cGAMP, a cyclic dinucleotide containing mixed phosphodiester linkages and produced by cytoplasmic DNA sensor cGAS. Here, we reported on a novel transcript isoform of STING designated STING-β that dominantly inhibits innate nucleic acid sensing. STING-β without transmembrane domains was widely expressed at low levels in various human tissues and viral induction of STING-β correlated inversely with IFN-β production...

The present study aimed at identifying the plasma miRNA profile of antiphospholipid syndrome patients and to investigate the potential role of specific circulating miRNAs as non-invasive disease biomarkers. Ninety antiphospholipid syndrome patients and 42 healthy donors were recruited. Profiling of miRNAs by PCR-array in plasma of antiphospholipid syndrome patients allowed identifying a set of miRNAs differentially expressed and collectively involved in clinical features. Logistic Regression and ROC-curve analyses identified a signature of 10 miRNA ratios as biomarkers of disease...

Interface dermatitis (ID) is a characteristic histological pattern which occurs in autoimmune and chronic inflammatory skin diseases. It is unknown whether a common mechanism orchestrates this distinct type of skin inflammation. Here we investigated the overlap of two different ID positive skin diseases, lichen planus (LP) and lupus erythematosus (LE). The shared transcriptome signature pointed towards a strong type I immune response and biopsy derived T cells were dominated by IFN-γ and TNF-α positive cells...

Cardiovascular disease associated with obesity and autoimmunity is the leading cause of death in these populations and significant residual risk remains despite current treatment approaches. Obesity, type 1 diabetes mellitus (T1DM), rheumatoid arthritis (RA), and systemic lupus erythematosus (SLE) are linked to chronic inflammation, and subjects with these disorders have characteristic shifts in their gut microbiome composition. Recent data suggest that alterations in gut microbial and metabolic composition may be responsible, in part, for induction of chronic inflammation, thus promoting cardiovascular disease...

OBJECTIVE: Human papillomavirus (HPV) is the most common sexually transmitted agent in the world. HPV6b is a low-risk type of HPVs that causes benign verrucous hyperplastic lesions of the skin and anal genital mucosa. Previous research has indicated that HPV genotype 6 is sometimes associated with high-grade lesions and anal cancer. The pathogenesis of low-risk HPV infection and its relationship to high-risk HPV is not clear at present. The E7 protein, which is encoded by HPV early -expressing genes, plays an important role in HPV infection...

It is uncertain whether antiphospholipid antibodies (APAs) increase the risk of recurrence after a first unprovoked venous thromboembolism (VTE). We tested for anticardiolipin antibodies, anti-β2 glycoprotein 1 antibodies, and lupus anticoagulant on 2 occasions ∼6 months apart in 307 patients with a first unprovoked VTE who were part of a prospective cohort study. We then determined if APAs were associated with recurrent thrombosis in the 290 patients who stopped anticoagulant therapy in response to negative D-dimer results...

Mature microRNAs (miRNAs) are single-stranded RNAs with approximately 18-25 bases, and their sequences are highly conserved among animals. miRNAs act as posttranscriptional regulators by binding mRNAs, and their main function involves the degradation of their target mRNAs. Recent studies revealed altered expression of miRNAs in the kidneys during the progression of acute kidney injury (AKI) and chronic kidney disease (CKD) in humans and experimental rodent models by using high-throughput screening techniques including microarray and small RNA sequencing...
