RESUMO

Aim: An existing meta-analysis have investigated the PTX3 levels in systemic lupus erythematosus (SLE) patients, but the number of studies has increased since 2015. We performed an updated meta-analysis to derive a more accurate estimation. Methods: The related literature was systematically searched in PubMed, Embase and The Cochrane Library database (up to 28 February, 2019). Results: SLE patients had significantly higher PTX3 levels than controls (pooled SMD = 0.48; 95% CI: 0.11-0.84). Subgroup analyses indicated SLE patients from non-Caucasian population, with age ≥45 years, SLE disease activity index (SLEDAI) ≥10 and plasma samples had higher PTX3 levels. Conclusion: Circulating PTX3 levels are increased in SLE patients, and affected by age, ethnicity, SLEDAI and sample type.

RESUMO

Aryl hydrocarbon receptor (AhR), a type of transcriptional factor, is widely expressed in immune cells. The activation of AhR signaling pathway depends on its ligands, which exist in environment and can also be produced by metabolism. Normal expressions of AhR and AhR-mediated signaling may be essential for immune responses, and effects of AhR signaling on the development and function of innate and adaptive immune cells have also been revealed in previous studies. Recent studies also indicate that aberrant AhR signaling may be related to autoimmune diseases, including rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), multiple sclerosis (MS), autoimmune uveitis (AU), autoimmune diabetes, Behcet's disease (BD) and myasthenia gravis (MG). Moreover, administration of AhR ligands or drugs has been proven effective for improving pathological outcomes in some autoimmune diseases or models. In this review, we summarize the effects of AhR on several innate and adaptive immune cells associated with autoimmunity, and the mechanism on how AhR participates in autoimmune diseases. In addition, we also discuss therapeutic potential and application prospect of AhR in autoimmune diseases, so as to provide valuable information for exploring novel and effective approaches to autoimmune disease treatments.

RESUMO

BACKGROUND Hospitalizations in patients with systemic lupus erythematosus (SLE) have been reported from different regions in the world. This study aimed to evaluate the annual hospitalization rate, causes of hospitalization, and potential factors associated with frequency of hospitalization in Chinese patients. MATERIAL AND METHODS We performed an ambispective cohort study for hospitalized patients with SLE in a Chinese single center. Data on demographics, organ involvements, laboratory abnormities, clinical treatments, causes of hospitalization, and survival outcomes were recorded at the time of SLE diagnosis and during a follow-up period. Poisson regression models were created to identify the potential factors associated with frequency of hospitalization. RESULTS Of 526 patients with SLE, 242 patients (46%) had 1 or more admissions amounting to a total of 449 times during a median follow-up period of 4.73 years. The annual hospitalization rate was 18% and death occurred in 2.5% of total admissions. SLE flare, infection and pregnancy-related morbidity were the most common causes of hospitalization. Besides, the multivariate Poisson regression analysis revealed that decreased albumin, decreased renal function, and high disease damage were the risk factors for more frequency of hospitalization, whereas positive anti-SSA antibody and use of hydroxychloroquine were protective factors. CONCLUSIONS Nearly half of patients (46%) with SLE experience 1 or more hospitalizations, mainly due to SLE flare, infection, and pregnancy-related morbidity. Lupus patients with decreased albumin, decreased renal function, and high disease damage are more susceptible to have frequent hospitalization.

RESUMO

PURPOSE: Accumulating evidence has linked long noncoding RNAs (lncRNAs) to autoimmune and inflammatory disorders. This study aimed to detect the expression levels of five lncRNAs (lnc0640, lnc3643, lnc5150, lnc7514 and lncagf) in peripheral blood mononuclear cells (PBMCs) of patients with systemic lupus erythematosus (SLE), as well as their correlation with clinical and laboratory features. MATERIALS/METHODS: We recruited 76 patients with SLE and 71 normal controls into the present study, and obtained PBMCs from the blood samples of all study subjects. Expression levels of lncRNAs were determined by quantitative real-time reverse transcription polymerase chain reaction and their associations with clinical and laboratory characteristics were analyzed. RESULTS: Lnc5150 expression levels were statistically significantly decreased (Z=-6.016, P < 0.001) compared with normal controls. Lnc3643 levels were also statistically significantly decreased in SLE patients with proteinuria compared with those without (Z=-2.934, P = 0.003), and the lnc7514 levels were statistically significantly lower in anti-dsDNA(+) patients compared with anti-dsDNA(-) patients. The expression levels of lnc3643 were correlated with C-reactive protein and erythrocyte sedimentation rate (ESR), lnc7514 was correlated with disease activity and ESR (all P < 0.01). CONCLUSIONS: The aberrant lncRNA expression levels and their associations with laboratory features in SLE suggest their important role in SLE pathogenesis.

RESUMO

Aim: To derive a precise estimation on plasma/serum level of SOD, GPx, CAT and GSH levels in systemic lupus erythematosus (SLE) patients. Methods: A total of 36 articles from electronic databases were finally included with 1120 SLE patients and 1024 healthy controls considered for antioxidant levels. Results: The levels of CAT and GSH were significantly lower, while SOD and GPx levels were slightly lower in patients with SLE compared with healthy controls. Subgroup analysis indicated that Arabs, ages ≥40 and SLE diseases activity index <6 had a significant association of SOD and CAT levels with SLE patients. Conclusion: The results demonstrated a significant lower CAT and GSH levels and also revealed no significant difference for SOD and GPx levels in SLE patients.

RESUMO

PURPOSE: To explore the association of adiponectin (AD) and adiponectin receptor (ADR) gene single-nucleotide polymorphisms (SNPs) with genetic susceptibility to rheumatoid arthritis (RA) in a Chinese population. STUDY DESIGN: Five AD SNPs (rs266729, rs2241766, rs1063537, rs2082940 and rs1063539) and two ADR SNPs (rs7539542 and rs12342) were genotyped in a cohort of 617 patients with RA and 639 healthy controls. Seven SNPs were genotyped using TaqMan genotyping assays on the Fluidigm 192.24 system. The concentration of AD in plasma was examined by ELISA. RESULTS: Patients with RA showed a considerably lower plasma level of AD than healthy controls (p=0.002). No significant differences were observed for the distribution of allele and genotype frequencies of rs266729, rs2241766, rs2082940, rs1063539, rs7539542 and rs12342 SNPs between patients with RA and controls. The genotype effects of recessive and dominant models were also analysed, but no marked evidence for association was found. However, further analysis in female patients with RA showed that the frequency of the AD gene rs1063539 GG genotype was nominally significantly higher in patients who were anti-cyclic citrullinated peptide (anti-CCP) antibody-positive (p=0.040). No significant differences in serum AD level were observed in patients with RA with different genotypes. CONCLUSIONS: rs266729, rs2241766, rs2082940 and rs1063539 in the AD gene and rs7539542 and rs12342 in the ADR gene are possibly not associated with genetic susceptibility to RA, but the A D gene rs1063539 locus was possibly associated with anti-CCP in RA female patients.

RESUMO

OBJECTIVE: Although patients with psoriasis frequently report seasonal changes in their symptoms, the seasonality of psoriasis has rarely been explored. This study aims to investigate the seasonal pattern of and global public interest in psoriasis using Google search data. METHODS: Internet search data were collected from Google Trends. Data on the relative search volume (RSV) from January 2004 to December 2018 were retrieved using the term psoriasis. Cosinor analyses were conducted to examine the seasonality of psoriasis using data from two southern hemisphere countries (Australia and New Zealand) and four northern hemisphere countries (USA, Canada, UK and Ireland). RESULTS: Overall, searches for psoriasis steadily decreased between 2004 and 2010, and then rose from 2011 to 2018. On cosinor analyses, RSV of 'psoriasis' displayed a significant seasonal variation worldwide (p<0.025). Further analyses confirmed the seasonality of psoriasis-related RSV in Australia, New Zealand, USA, Canada, UK and Ireland (p<0.025 for all), with peaks in the late winter/early spring months and troughs in the late summer/early autumn months. The top 11 rising topics were calcipotriol/betamethasone dipropionate, ustekinumab, apremilast, shampoo, eczema, guttate psoriasis, seborrhoeic dermatitis, dermatitis, psoriatic arthritis, atopic dermatitis and arthritis. CONCLUSION: There was a significant seasonal pattern for psoriasis, with peaks in the late winter/early spring and troughs in the late summer/early autumn. Further studies are warranted to confirm the seasonal pattern of psoriasis using clinical data and to explore the underlying mechanisms.

RESUMO

The 3' repair exonuclease 1 (TREX1) gene is the major DNA-specific 3'-5 'exonuclease of mammalian cells which reduces single- and double-stranded DNA (ssDNA and dsDNA) to prevent undue immune activation mediated by nucleic acid. TREX1 is also a crucial suppressor of self-recognition that protect the host from inappropriate autoimmune activations. It has been revealed that TREX1 function is necessary to prevent host DNA accumulating after cell death which could actuate an autoimmune response. Mutations in the human TREX1 gene have recently been shown to Aicardi-Goutières syndrome (AGS), familial chilblain lupus (FCL), systemic lupus erythematosus (SLE) and retinal vasculopathy with cerebral leukodystrophy (RVCL). In the manuscript, we will discuss in detail the latest advancement in studying the role of TREX1 in autoimmune disease.

RESUMO

OBJECTIVE: To investigate the plasma galectin-3 levels in systemic lupus erythematosus (SLE) patients and its relations with clinical and laboratory features. METHODS: A total of 180 subjects with 90 patients with SLE (8 male, 82 female, mean age 37.86 ± 13.98 years) and 90 healthy controls (8 male, 82 female, mean age 36.54 ± 10.89 years) were included. Plasma galectin-3 levels were detected by enzyme-linked immunosorbent assay (ELISA). RESULTS: There was no significant difference in age and gender distribution between SLE patients and healthy controls (both P > .05). Plasma galectin-3 level was not significantly different between SLE patients and controls (P = .982) (P > .05). No significant difference was found regarding galectin-3 levels between SLE with nephritis and those without nephritis (P > .05); no significant difference was found between less active SLE and more active SLE (P > .05). Galectin-3 levels were inversely related to immune globulin M (r = -.303, P < .05), while no significant correlation between galectin-3 levels and other quantitative laboratory parameters were observed (all P > .05). CONCLUSIONS: In summary, plasma galectin-3 level was not significantly different between SLE patients and controls (P = .982). Further studies are needed to elucidate the role of galectin-3 in SLE.

RESUMO

Background: Semaphorin-3A (Sema3A) and Semaphorin-7A (Sema7A) play crucial roles in immune system by inhibiting T cell proliferation and leading to the secretion of pro-inflammatory cytokines. Increasing evidence suggest that Sema3A and Sema7A may link to the development and pathogenesis of systemic lupus erythematosus (SLE). Objective: This study aims to evaluate the association of Sema3A, Sema7A gene single-nucleotide polymorphisms (SNPs) with susceptibility to SLE. Methods: There were 495 SLE patients and 493 healthy controls in the study. Sema3A gene and Sema7A gene were genotyped by improved multiple ligase detection reaction (iMLDR), their plasma expression levels were detected by enzyme-linked immunosorbent assay (ELISA). Results: No differences in genotype and allele frequencies of these SNPs were observed between SLE patients and healthy controls. However, analysing Sema3A and Sema7A SNPs with clinical manifestations of SLE indicated that, in Sema3A, the A allele frequencies of rs7804122 polymorphism was higher in patients with oral ulcers. In Sema7A, there were differences in allele frequencies of the rs2075589 and rs28362930 polymorphisms between SLE patients with haematological disorder and those without. The GG genotype and G allele frequencies of rs28362930 and the CC genotype, and C allele frequencies of rs741761 were both related to discoid rash in SLE patients. The allele frequency of G (rs28362930) was higher in SLE patients with renal disorder. There were differences in the genotype frequencies and allele frequencies of rs741761 between SLE patients with and without arthritis. No differences in plasma Sema3A and Sema7A levels were detected in SLE patients of different genotypes. Conclusions: Sema3A and Sema7A gene polymorphisms are not related to SLE genetic susceptibility, but may link to several clinical features of SLE.

RESUMO

A growing body of data suggests that semaphorins are involved in both normal and pathological immune responses, as well as autoimmune pathologies. To investigate the plasma semaphorin 3A (Sema3A) and semaphorin 7A (Sema7A) levels in systemic lupus erythematosus (SLE) patients and their correlation with clinical manifestations and laboratory indexes, a two-step method was applied. First, 80 SLE patients and 80 healthy controls were recruited for comparing serum Sema3A and Sema7A concentrations. Second, 40 rheumatoid arthritis (RA) patients and 40 sjögren's syndrome (SS) patients were then included as disease controls. Plasma Sema3A and Sema7A concentrations were detected by ELISA. There were significant differences in Sema3A and Sema7A among four groups. When compared to healthy controls, both Sema3A and Sema7A levels were decreased in SLE and increased in RA; increased Sema3A level and decreased Sema7A level were found in SS. There were significant differences in Sema3A concentration between SLE and RA, SLE and SS. Moreover, there were significant differences in Sema7A level between SLE and RA, SS and RA. However, no significant differences in Sema3A between SS and RA and no significant differences in Sema7A between SS and SLE were observed. Both plasma Sema3A and Sema7A levels were correlated with anti-SSA and IgM. Area under curve (AUC) of the receiver operating characteristic (ROC) curve for Sema3A and Sema7A were 0.535 (0.455-0.613) and 0.671 (0.594-0.742), respectively. Aberrant Sema3A and Sema7A expression and their clinical associations in SLE suggest their important role in this disease.

RESUMO

AIM: The indicators for measuring vitamin D are various, and 25-hydroxyvitamin D (25(OH)D) is considered as the optimal indicator of total vitamin D levels. In this study, we aim to deeply explore the 25(OH)D status in systemic lupus erythematosus (SLE) patients, and evaluate its relation to SLE risk and disease severity. METHODS: Literature about 25(OH)D status and its associations with SLE were searched in Pubmed, Embase and Cochrane Library databases. Standardized mean difference (SMD), odds ratio (OR) and corresponding 95% confidence interval (95% CI) were illustrated by forest plots, and correlation coefficients (r) were combined by generic inverse variance method. Heterogeneity and publication bias were quantified by I-squared (I2 ) test, funnel plot and Egger's test, respectively. Sensitivity analyses were further examined by leave-one-out method. RESULTS: Nineteen articles were included into our meta-analysis. The overall results showed that compared with the healthy controls, the circulating 25(OH)D levels were significantly lower in SLE patients (pooled SMD = -1.63, 95% CI: -2.51 to -0.76). Subgroup analysis revealed that compared with the healthy controls, SLE patients of Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) ≥ 10, Arab and European ethnicity, all 4 seasons, no vitamin D supplement, had significantly lower circulating 25(OH)D levels; no significant differences were observed in SLE patients of SLEDAI < 10, mixed ethnicity, spring, summer, vitamin D supplement, respectively; no matter the changes of age, disease duration, and the therapy of corticosteroid or immunosuppressive or neither, circulating 25(OH)D levels were significantly reduced in SLE patients. The deficiency, insufficiency and sufficiency of vitamin D could significantly elevate, slightly decrease (not significantly), significantly decrease SLE risk, respectively (pooled OR = 4.37, 95% CI: 1.49 to 12.84; pooled OR = 0.52, 95% CI: 0.22 to 1.26; pooled OR = 0.31, 95% CI: 0.15 to 0.63). Circulating 25(OH)D levels were inversely associated with SLEDAI (pooled correlation coefficient = -0.50, 95% CI: -0.8278 to -0.1689). CONCLUSIONS: Compared with healthy controls, 25(OH)D levels are significantly lower in SLE patients, which is influenced by disease activity, ethnicity, seasons and vitamin D supplement; no matter the change of age, diseases duration and therapy of corticosteroid or immunosuppressive or neither, 25(OH)D levels are significantly decreased in SLE patients; the deficiency, insufficiency and sufficiency of vitamin D could significantly elevate, slightly decrease, and significantly decrease SLE risk, respectively; and 25(OH)D levels inversely correlate with SLEDAI.

RESUMO

Autoimmune diseases are a broad spectrum of disorders involved in the imbalance of T-cell subsets, in which interplay or interaction of Th1, Th17 and Tregs are most important, resulting in prolonged inflammation and subsequent tissue damage. Pathogenic Th1 and Th17 cells can secrete signature proinflammatory cytokines, including interferon (IFN)-γ and IL-17, however Tregs can suppress effector cells and dampen a wide spectrum of immune responses. Melatonin (MLT) can regulate the humoral and cellular immune responses, as well as cell proliferation and immune mediators. Treatment with MLT directly interferes with T cell differentiation, controls the balance between pathogenic and regulatory T cells and regulates inflammatory cytokine release. MLT can promote the differentiation of type 1 regulatory T cells via extracellular signal regulated kinase 1/2 (Erk1/2) and retinoic acid-related orphan receptor-α (ROR-α) and suppress the differentiation of Th17 cells via the inhibition of ROR-γt and ROR-α expression through NFIL3. Moreover, MLT inhibits NF-κB signaling pathway to reduce TNF-α and IL-1ß expression, promotes Nrf2 gene and protein expression to reduce oxidative and inflammatory states and regulates Bax and Bcl-2 to reduce apoptosis; all of which alleviate the development of autoimmune diseases. Thus, MLT can serve as a potential new therapeutic target, creating opportunities for the treatment of autoimmune diseases. This review aims to highlight recent advances in the role of MLT in several autoimmune diseases with particular focus given to novel signaling pathways involved in Th17 and Tregs as well as cell proliferation and apoptosis.

RESUMO

P2X7 receptor (P2X7R), a distinct ligand-gated ion channel, is a member of purinergic type 2 receptor family with ubiquitous expression in human body. Previous studies have revealed a pivotal role of P2X7R in innate and adaptive immunity. Once activated, it will meditate some vital cascaded responses including the assembly of nucleotide-binding domain (NOD) like receptor protein 3 (NLRP3) inflammasome, non-classical secretion of IL-1ß, modulation of cytokine-independent pathways in inflammation such as P2X7R- transglutaminase-2 (TG2) and P2X7R-cathepsin pathway, activation and regulation of T cells, etc. In fact, above responses have been identified to be involved in the development of autoimmunity, specifically, the NLRP3 inflammasome could promote inflammation in massive autoimmune diseases and TG2, as well as cathepsin may contribute to joint destruction and degeneration in inflammatory arthritis. Recently, numerous evidences further suggested the significance of P2X7R in the pathogenesis of autoimmune diseases, including systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), inflammatory bowel disease (IBD), multiple sclerosis (MS), etc. In this review, we will succinctly discuss the biological characteristics and summarize the recent progress of the involvement of P2X7R in the development and pathogenesis of autoimmune diseases, as well as its clinical implications and therapeutic potential.

RESUMO

Identify long non-coding RNAs (lncRNAs) that might serve as biomarkers for systemic lupus erythematosus (SLE) and explore the biological functions of the identified lncRNAs. In the screening phase, we examined the lncRNA expression profile of plasma samples from 24 patients with SLE and 12 healthy controls (HCs) using lncRNA microarray with pooled samples. The candidate lncRNAs were verified in individual samples by quantitative real-time (qRT)-PCR. In the independent validation stage, the identified lncRNAs were evaluated in 240 patients with SLE and 120 HCs. The identified lncRNAs were assessed further in an external validation stage including patients with rheumatoid arthritis (RA) and primary Sjögren's syndrome (pSS). In addition, we constructed correlated expression networks including coding-non-coding co-expression and competing endogenous RNAs (ceRNAs). Plasma levels of linc0597, lnc0640, and lnc5150 were elevated in SLE patients compared with those of HCs, whereas levels of GAS5 and lnc7074 were decreased. Five lncRNAs were identified as potential SLE biomarkers with an area under the receiver operating characteristic curve (AUC) ranging from 0.604 to 0.833 in the independent validation phase. This panel of five lncRNAs had high diagnostic accuracy for SLE (AUC = 0.966) and distinguished SLE from RA and pSS (AUC = 0.683 and 0.910, respectively). Co-expression analysis showed that GAS5, lnc0640, and lnc5150 may participate in the SLE pathogenesis through the MAPK pathway. The ceRNA network indicated that GAS5, lnc0640, lnc3643, lnc6655, and lnc7074 bind competitively with microRNAs regulating the expression of target genes. Aberrant expression and related pathways suggest the important role of lncRNAs in SLE pathogenesis. In addition, the panel of five lncRNAs (GAS5, lnc7074, linc0597, lnc0640, and lnc5150) in plasma could be used as SLE biomarkers.

RESUMO

Autoimmune diseases (ADs) are a broad spectrum of disorders featured by the body's immune responses being directed against its own tissues, resulting in prolonged inflammation and subsequent tissue damage. Recently, the exposure to ambient air pollution has been implicated in the occurrence and development of ADs. Mechanisms linking air pollution exposures and ADs mainly include systemic inflammation, increased oxidative stress, epigenetic modifications induced by exposures and immune response caused by airway damage. The lung may be an autoimmunity initiation site in autoimmune diseases (ADs). Air pollutants can bind to the Aryl hydrocarbon receptor (AHR) to regulate Th17 and Treg cells. Oxidative stress and inducible bronchus associated lymphoid tissue caused by the pollutants can influence T, B cells, resulting in the production of proinflammatory cytokines. These cytokines stimulate B cell and dendritic cells, resulting in a lot of antibodies and self-reactive T lymphocytes. Moreover, air pollutants may induce epigenetic changes to contribute to ADs. In this review, we will concern the associations between air pollution and immune-inflammatory responses, as well as mechanisms linking air pollution exposure and autoimmunity. In addition, we focus on the potential roles of air pollution in major autoimmune diseases including systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), multiple sclerosis (MS), and type 1 diabetes mellitus (T1DM).

RESUMO

Interleukin-35 (IL-35) exerts crucial roles in the pathogenesis and development of systemic lupus erythematosus (SLE), in this study we aim to explore the associations between IL-35 gene polymorphisms and the susceptibility, clinical features and plasma IL-35 levels of SLE patients, respectively. 490 SLE patients and 489 healthy controls were recruited in our study. The correlations between the polymorphisms of seven SNPs of IL-35 encoding gene and the susceptibility, main clinical manifestations of SLE were evaluated, respectively. Plasma IL-35 levels were assessed in 76 SLE patients, and the associations between plasma IL-35 levels and the polymorphisms of genotyped SNPs were explored. There were significant associations between the polymorphisms of rs4740 and the occurrence of renal disorder, hematological disorder in SLE patients, respectively (p = 0.001; p = 0.001). In addition, there were no significant associations observed between the genotype frequencies of genotyped SNPs and the risk of SLE, plasma IL-35 levels, respectively. The polymorphism of rs4740 of IL-35 encoding gene is associated with the occurrence of renal disorder and hematological disorder of SLE patients.
