Common polymorphisms of microRNA gene MIR146A were reported as associated with different autoimmune diseases, include systemic lupus erythematosus, psoriatic arthritis, asthma and ankylosing spondylitis. In this study we investigated MIR146A SNPs in Chinese people with ankylosing spondylitis. Three common SNPs: rs2910164, rs2431697 and rs57095329 were selected and genotyped in 611 patients and 617 controls. We found no association between these SNPs and ankylosing spondylitis in our samples. 相似文献

In order to study the association between FcγRIIa gene polymorphisms and the risk of systemic lupus erythematosus (SLE) and
lupus nephritis, relevant studies were identified from electronic databases. A meta-analysis of relevant studies was performed
for heterogeneity test and pooled OR calculation. When all groups were pooled, a significant association of FcγRIIa-R131 allele and increased SLE risk was found. But this association
was not observed in lupus nephritis. In the subgroup analysis, a clear effect of R allele in SLE was shown in European and
Asian subgroups. Similarly, RR homozygous genotype was found to be a risk factor of SLE and lupus nephritis. The association
between RR genotype and SLE was shown in European and Asian descents. However, the association between RR genotype and lupus
nephritis was not found in any ethnic subgroups. Taken together, our study suggests that the FcγRIIa-R/H131 polymorphism might
contribute to the susceptibility to SLE and lupus nephritis. 相似文献

AbstractRelationship between vitamin D receptor (VDR) gene polymorphism and the risk of systemic lupus erythematosus (SLE) from the published reports are still conflicting. This study was conducted to evaluate the relationship between VDR BsmI (rs1544410), Fok1 (rs2228570), ApaI (rs7975232) and TaqI (rs731236) gene polymorphism and the risk of SLE using meta-analysis method. The association studies were identified from PubMed and Cochrane Library on 1 March 2014, and eligible investigations were included and synthesized using meta-analysis method. Thirteen reports were recruited into this meta-analysis for the association of VDR gene polymorphism with SLE susceptibility. In this meta-analysis for overall populations, the BsmI B allele and bb genotype, Fok1 f allele and ff genotype, and ApaI aa genotype, were associated with the risk of SLE. In Asians, the BsmI B allele, BB genotype and bb genotype, Fok1 f allele and ff genotype were associated with the risk of SLE. In Africans, the BsmI B allele, BB genotype and bb genotype, Fok1 f allele and ff genotype, ApaI A allele, AA genotype and aa genotype were associated with the risk of SLE. However, VDR BsmI, Fok1, ApaI and TaqI gene polymorphism were not associated with the risk of SLE in Caucasians. In conclusion, the BsmI B allele and bb genotype, Fok1 f allele and ff genotype were associated with the risk of SLE in overall populations, and in Asians, but these associations were not found in Caucasians. However, more studies should be conducted to confirm it. 相似文献

The pathogenesis of systemic lupus erythematosus (SLE) is complex, with several susceptibility genes and environmental factors involved in its development and clinical manifestation. Currently, there is a great amount of interest in the identification of biomarkers, as cytokines, that can quantify the susceptibility of SLE, the risk of future organ involvement, and association of their changes with disease activity. To investigate the associations between polymorphisms in the gene of Interferon gamma (IFN-γ) and in the promoter of the Interleukin-10 (IL-10) gene and SLE. The polymorphisms +874 T/A (rs2430561) in the IFN-γ gene and ?1082G/A (rs1800896) in the IL-10 promoter were determined in 99 SLE patients and 100 healthy controls among women Brazilian using the refractory mutation system polymerase chain reaction method. Disease activity was assessed using the SLE activity index. There were significant differences in the distribution of the genotype T/A in IFN-γ gene polymorphism (+874) (χ 2 = 7.168; P = 0.0074) and the genotype G/A in IL-10 promoter polymorphism (?1082) (χ 2 = 4.654; P = 0.0310) between the SLE and control groups. However, no association was observed between clinical features and the polymorphisms studied. This study presents preliminary evidence for association between IL-10 and IFN-γ polymorphism and SLE susceptibility, but not with clinical features in a Northeast population from Brazil. 相似文献

To explore the association of LEP and leptin receptor (LEPR) gene single‐nucleotide polymorphisms (SNPs) with susceptibility to systemic lupus erythematosus (SLE) in a Chinese population. Four LEP SNPs (rs11761556, rs12706832, rs2071045 and rs2167270) and nine LEPR SNPs (rs10749754, rs1137100, rs1137101, rs13306519, rs8179183, rs1805096, rs3790434, rs3806318 and rs7518632) were genotyped in a cohort of 633 patients with SLE and 559 healthy controls. Genotyping of SNPs was performed with improved multiple ligase detection reaction (iMLDR). No significant differences were detected for the distribution of allele and genotype frequencies of all 13 SNPs between patients with SLE and controls. The genotype effects of recessive, dominant and additive models were also analysed, but no significant evidence for association was detected. However, further analysis in patients with SLE showed that the TT genotype and T allele frequencies of the LEP rs2071045 polymorphism were nominally significantly higher in patients with pericarditis (P = 0.012, P = 0.011, respectively). In LEPR, the GA/AA genotype and A allele frequencies of the rs1137100 polymorphism were both nominally associated with photosensitivity in patients with SLE (P = 0.043, P = 0.018, respectively). Moreover, the genotype and allele distribution of rs3806318 were also nominally associated with photosensitivity in patients with SLE (P = 0.013, P = 0.008, respectively). No significant differences in serum leptin levels were observed in patients with SLE with different genotypes. In summary, LEP and LEPR SNPs are not associated with genetic susceptibility to SLE, but may contribute to some specific clinical phenotype of this disease; further studies are necessary to elucidate the exact role of LEP and LEPR genes in the pathogenesis of SLE. 相似文献

Toll-like receptor 9 (TLR9) plays an important role in the induction and regulation of the innate immune system or adaptive
immune responses. Genetic variations within human TLR9 have been reported to be associated with a range of immune-related diseases, such as asthma, systemic lupus erythematosus
(SLE) and so on. Family-based association analysis was performed to further investigate whether a single nucleotide polymorphism
(rs352140) in the exon 2 region of TLR9 gene is associated with susceptibility to SLE in a Chinese population. A total of 77 patients with SLE from 74 nuclear families,
aged from 12 to 63 years, were enrolled according to 1997 criteria of American College of Rheumatology (ACR), 211 family members
of these patients were also included. Genotyping was performed by PCR-restriction fragment length polymorphism (PCR-RFLP)
assay. Among 77 patients with SLE, the CC, CT and TT genetype frequencies of the SNP (rs352140) were 20.8, 61.0 and 18.2%,
respectively. Single loci analysis suggested that the T allele at position of rs352140 was significantly associated with the
susceptibility to SLE (Z = 2.357, P = 0.018402) in dominant model, but not in additive or recessive model. Genetype analysis showed that individuals with CT
genetype had greater susceptibility to SLE than those without (Z = 2.004, P = 0.045067). Our study suggests that a single nucleotide polymorphism (rs352140) in the exon 2 region of TLR9 gene may be a susceptibility factor for SLE in Chinese population. 相似文献

Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disorder. MASP2 is a mediator that plays an important role in complement system. As dysregulation of the complement system has been demonstrated to correlate with SLE pathogenesis, the role of MASP2 in lupus has not been widely discussed. In the present study, serum levels of MASP2 were evaluated in 61 lupus patients and 98 healthy controls by training cohort, and then a validation cohort including 100 lupus, 100 rheumatoid arthritis, 100 osteoarthritis, 100 gout, 44 Sjogren's syndrome, 41 ankylosing spondylitis patients confirmed the findings. Receiver operating characteristic (ROC) curve analysis determined the discriminatory capacity for serum MASP2. PCR methods tested the association of MASP2 gene polymorphisms (rs7548659, rs17409276, rs2273346, rs1782455 and rs6695096) and SLE risk. Impact of polymorphism on MASP2 serum levels was evaluated as well. Results showed that serum levels of MASP2 were significantly higher in lupus patients and correlated with some clinical, laboratory characteristics in the training cohort, and were much higher as compared to that in different rheumatic diseases patients in the validation cohort. Serum MASP2 showed a good diagnostic ability for lupus. Genotype frequencies and allele frequency of polymorphisms rs7548659, rs2273346 were strongly related to SLE risk, and genotypes of rs17409276, rs1782455, rs76695096 were significantly correlated with lupus genetic susceptibility. Interestingly, patients carrying GA genotype of rs17409276, TT, TC genotype of rs6695096 showed higher levels of serum MASP2. The findings suggested that MASP2 may be a potential disease marker for lupus, and correlate with SLE pathogenesis. 相似文献

Our previous studies showed elevated tumor necrosis factor-like ligand 1 aberrance (TL1A) expression in systemic lupus erythematosus (SLE). However, TL1A polymorphisms with SLE susceptibility remain to be elucidated. In addition, we made meta-analysis to evaluate the relationship of TL1A polymorphisms and autoimmune diseases owing to inconsistent results. The present research was carried out by 404 SLE, 150 primary Sjogren's syndrome (pSS) patients, and 574 healthy individuals. Three TL1A polymorphisms (rs3810936, rs6478109, rs7848647) were genotyped using TaqMan genotyping assay. Then, the meta-analysis was performed by collecting the present case-control study and previously published research. Results showed that genotypes of rs3810936, rs7848647 were different between SLE patients and healthy controls, whereas no significant association was observed in the three polymorphisms and pSS patients. Genotypes distribution of rs6478109, rs7848647 were strongly related to lupus nephritis within SLE (p = 0.004, p = 0.011), respectively. Moreover, combined meta-analysis consisted of ten comparative research involving 4,305 patients and 5,600 controls. An association between autoimmune diseases and rs6478109 polymorphism was found. Our findings indicate that gene polymorphisms (rs3810936, rs7848647) of TL1A might correlate with lupus. 相似文献

The aim of this study was to determine whether the three functional interleukin-18 (IL-18) promoter ?607 C/A (rs1946518), ?137 G/C (rs187238), and ?1297 C/T (rs360719) polymorphisms confer susceptibility to systemic lupus erythematosus (SLE) in ethnically different populations. Meta-analysis was conducted on the associations between these IL-18 polymorphisms and SLE using; (1) allele contrast, (2) the recessive model, (3) the dominant model, and (4) the additive model. A total of 11 comparisons (nine studies) involving 8,453 subjects (2,928 SLE patients and 5,525 controls) were included in the meta-analysis. In all study subjects, meta-analysis showed no association between SLE and the IL-18 ?607 C allele (odds ratio [OR] = 1.065, 95 % confidence interval [CI] = 0.870–1.303, p = 0.541). However, stratification by ethnicity indicated a significant association between this allele and SLE in Europeans (OR = 0.864, 95 % CI = 0.757–0.986, p = 0.031), but not in Asians (OR = 1.230, 95 % CI = 0.902–1.676, p = 0.190). Meta-analyses showed the same pattern for the IL-18 ?607 C allele using the dominant and additive models. Meta-analysis of the IL-18 ?137 G/C polymorphism showed no association between SLE and the IL-18 ?137 G allele in all study subjects (OR = 0.916, 95 % CI = 0.836–1.003, p = 0.057), but stratification by ethnicity indicated a significant association between this allele and SLE in Asians (OR = 0.792, 95 % CI = 0.629–0.997, p = 0.047), but not in Europeans (OR = 0.930, 95 % CI = 0.839–1.032, p = 0.171). Furthermore, meta-analysis showed that the IL-18 ?1297 C allele was significantly associated with SLE in all study subjects and in Europeans (OR = 1.240, 95 % CI = 1.052–1.482, p = 0.010 and OR = 1.303, 95 % CI = 1.050–1.617, p = 0.016). This meta-analysis shows that the IL-18 ?607 C/A and ?1297 C/T polymorphism are associated with the development of SLE in Europeans, and the IL-18 ?137 G/C polymorphism is associated with SLE in Asians. 相似文献

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease with diverse manifestations. Although the approval of new therapies includes only one agent in 50 years, a number of promising new drugs are in development. Lupus nephritis is a dreaded complication of SLE as it is associated with significant morbidity and mortality. Advancing the treatment of lupus nephritis requires well-designed clinical trials and this can be challenging in SLE. The major obstacles involve identifying the correct population of patients to enroll and ensuring that a clinically appropriate and patient-centered endpoint is being measured. In this review, we will first discuss the clinical utility of endpoints chosen to represent lupus nephritis in global disease activity scales. Second, we will review completed and active trials focused on lupus nephritis and discuss the endpoints chosen. There are many important lessons to be learned from existing assessment tools and clinical trials. Reviewing these points will help ensure that future efforts will yield meaningful disease activity measures and well-designed clinical trials to advance our understanding of lupus management. 相似文献

Systemic lupus erythematosus (SLE) is one of the common autoimmune diseases, with complex genetic components. Interleukin-21 (IL-21) is the most recently discovered member of the type-I cytokine family, which has a variety of effects on the immune system, including B cell activation, plasma cell differentiation, and immunoglobulin production. Previous studies have identified that IL-21 was associated with different autoimmune and inflammatory diseases, such as rheumatoid arthritis, multiple sclerosis and SLE. Variations in the DNA sequence in the IL-21 gene may lead to altered IL-21 production and/or activity, and thus this can modulate an individual's susceptibility to SLE. To test this hypothesis, we investigated the association of the IL-21 polymorphisms and its serum levels with the risk of SLE in a Chinese population. We analyzed three single nucleotide polymorphisms of IL-21 gene rs907715 C/T, rs2221903 T/C and rs2055979 C/A in 175 patients with SLE and 190 age- and sex-matched controls, using Snapshot SNP genotyping assays and DNA sequencing method. Soluble IL-21 (sIL-21) levels were measured by ELISA. There were significant differences in the genotype and allele frequencies of IL-21 gene rs2055979 C/A polymorphism between the group of patients with SLE and the control group (P < 0.05). sIL-21 levels were increased in patients with SLE compared with controls (P < 0.01). Moreover, genotypes carrying the IL-21 rs2055979 A variant allele were associated with increased IL-21 levels compared to the homozygous wild-type genotype in patients with SLE. The rs2055979 C/A polymorphism of IL-21 and its sIL-21 levels were associated with SLE in the Chinese population. Our data suggests that IL-21 gene may play a role in the development of SLE. 相似文献

Identification of the genetic basis of systemic lupus erythematosus (SLE) may contribute to the discovery of effective drugs before renal involvement. Our aim of this study was to estimate the association between Fc gamma receptor (FcγR) polymorphisms and SLE and renal involvement in Egyptian patients. FcγRIIB and FcγRIIA R131H gene polymorphisms were genotyped in 180 Egyptian adults. Genotyping for FcγRIIA R131H was performed using allele-specific PCR and FcγRIIB-Ile232 Thr polymorphism was genotyped using polymerase chain reaction restriction fragment length polymorphism (PCR–RFLP). The study showed that the homozygous genotype (Thr/Thr) of FcγRIIB significantly increased in all SLE patients (90 patients) and in SLE patients complicated with nephritis (61 patients). The Thr allele was significantly associated with an increased risk of the disease in all the patients and in patients complicated with nephritis. Our study demonstrated an association of FcγRIIB polymorphisms with SLE and lupus nephritis and a lack of association of FcγRIIA polymorphisms with SLE in the Egyptian patients. 相似文献

Hypoxia-inducible factor 1 (HIF-1) introduced the immune imbalance between Th17 and Treg cells, which may play an important role in the pathogenesis of systemic lupus erythematosus (SLE). The aim of the present study was to determine whether the HIF1A gene influences the susceptibility to SLE. A study on this relationship has not been conducted to date. A total of 3,793 subjects (1,497 SLE patients and 2,296 controls) were included in this study. The genotyping of five single-nucleotide polymorphisms (SNPs) (rs11549465, rs12434438, rs1957757, rs1951795, rs7143164) was determined by Sequenom MassARRAY technology. The statistical analysis was conducted using chi-square test. Odds ratio (OR) with 95 % confidence interval (CI) was calculated using unconditional logistic regression with adjustment of age and sex. The allele frequencies were not associated with the disease. No significant differences in genotype frequencies existed between the patients with SLE and the controls in all five SNPs. It is worth mentioning that the allele T at rs11549465, located at the exon sequence, revealed a trend but no significant difference towards the more frequent allele T in SLE than in controls (C versus T: OR?=?1.206, 95 % CI?=?0.972–1.495, p?=?0.088). The genotype effects of recessive, dominant, and codominant models were observed; however, no significant evidence for association was detected. Our findings suggest that the gene polymorphisms of HIF1A might not contribute to SLE susceptibility in the Chinese population. However, further studies are needed on an independent cohort from different genetic backgrounds to confirm HIF1A as an SLE genetic factor. 相似文献

MicroRNAs (miRNAs) may play important roles in SLE, but genetic polymorphisms of miRNAs and their relationships with various
autoantibodies present in SLE patients remain unclear. Here, we report that 213 SLE patients and 209 healthy individuals of
Chinese had been taken into this case–control studies, which had been performed by selecting two miRNAs (hsa-mir-146a rs2910164
G>C, and hsa-mir-499 rs3746444 T>C) to analyze the genetic polymorphisms. The single nucleotide polymorphism (SNP) variants
had been analyzed by PCR–RFLP and serum anti-ribonucleoprotein (anti-RNP), anti-Sm nuclear antigen (anti-Sm) antibodies had
been determined by an anti-ENA kit and serum anti-double-stranded DNA (anti-dsDNA) antibodies had been assessed by indirect
immunofluorescence. We found that hsa-mir-146a rs2910164 and hsa-mir-499 rs3746444 polymorphisms had no significant relationship
with SLE susceptibility. The genotype frequencies of rs2910164 (GG, CC, and GC) were 16, 37, and 47% in SLE patients, but
11, 39, and 50% in healthy group (P = 0.397), respectively; The genotype frequencies of rs3746444 (CC, TT, and TC) were 3, 74, and 23% in SLE patients, but 3,
76, and 22% in healthy group (P = 0.892), respectively. The G and C allele frequencies of rs2910164 were 39 and 61% in SLE patients, but 36 and 64% in healthy
group (P = 0.990), respectively. The C and T allele frequencies of rs3746444 were 15 and 85% in SLE patients, but 14 and 86% in healthy
group (P = 0.702), respectively. In addition, we also showed no significant difference in the distribution of rs2910164 and rs3746444
genotypes in each of the three antibodies (anti-RNP, anti-Sm, and anti-dsDNA). 相似文献

Virus-induced signaling adapter (VISA), an important adaptor protein linking both RIG-I and MDA-5 to downstream signaling
events, may mediates the activation of NF kappaB and IRFs and the induction of type I IFN. As the evidence has showed that
Toll-like receptors (TLRs), I-IFN and IFN-inducible genes contribute to the pathogenesis of systemic lupus erythematosus (SLE),
the aim of the current study was to investigate the possible associations between the VISA gene and SLE. Four single nucleotide
polymorphisms (SNPs), rs17857295, rs2326369, rs7262903, and rs7269320, in VISA gene were genotyped in 123 SLE patients and
95 healthy controls. Genotyping was performed using direct sequencing the purified PCR products. Associations were analyzed
by using the chi-square test and Fisher’s exact test. Haplotype analysis was performed using haploview and PHASE2.1. None
of the four SNPs was found to be associated with SLE. The four-SNPs haplotype analysis showed different effect between cases
and controls. While the SNPs, rs17857295 and rs2326369, were found to be associated with the renal nephritis and arthritis
of SLE patient, respectively. The SNPs rs7269320 showed associations with different manifestations. Our data reveal that polymorphisms
in the VISA gene may be related to disease susceptibility and manifestations of SLE. 相似文献
