Abstract
BACKGROUND Peptidyl arginine deiminase 4 (PADI4) has been implicated in Rheumatoid arthritis (RA) pathogenesis. Here we aimed to evaluate the association of PADI4 gene rs11203367 and rs1748033 single nucleotide polymorphisms (SNPs) with RA proneness. METHODS The mRNA expression of PADI4 was determined in the whole blood samples. The genotyping of PADI4 polymorphisms was conducted using allelic discrimination TaqMan genotyping Real-time PCR. RESULTS The alleles and genotypes of rs11203367 polymorphism were not associated with susceptibility to RA risk. The T allele (OR = 1.58, 95%CI: 1.21-2.04, P = 0.0005), TT genotype (OR = 2.79, 95%CI: 1.53-5.06, P = 0.0007), TC genotype (OR = 1.52, 95%CI: 1.04-2.23, P = 0.0291), dominant (OR = 1.72, 95%CI: 1.19-2.47, P = 0.0034) and recessive (OR = 2.19, 95%CI: 1.25-3.82, P = 0.0057) models of rs1748033 SNP were associated with higher risk of RA. There was a significant upregulation of PADI4 mRNA in the RA patients compared to controls. mRNA expression of PADI4 had significantly positive correlation with anti-CCP level (r = 0.37, P = 0.041), RF level (r = 0.39, P = 0.037), and CRP level (r = 0.39, P = 0.024). CONCLUSION PADI4 gene rs1748033 SNP was associated with increased RA risk. This polymorphism might affect the RA pathogenesis regardless of impressing the levels of PADI-4 in serum.

Abstract
BACKGROUND Juvenile systemic lupus erythematosus (JSLE) and juvenile idiopathic arthritis (JIA) are two common types of autoimmune diseases in children with unclear pathogenesis. Both peptidyl arginine deiminase type IV (PADI4) and interleukin 33 (IL-33) are the key molecular involved in immune responses in autoimmune diseases. Usually, it may share the same risk genetic alleles for autoimmune diseases. METHODS So measurement of PADI4 and IL-33 polymorphisms was conducted with 303 healthy controls, 144 JSLE patients and 160 JIA patients in this study. RESULTS It demonstrated that there was a significant association between PADI4 genotypes (rs2240340: CT, CT + CC), IL-33 genotype (rs1929992: TT) and JSLE susceptibility in Southwest China population. While no significant association with the risk of JIA were observed no matter at allelic or genotypic levels. CONCLUSIONS Our study reveals the importance of PADI4 and IL-33 polymorphisms with JSLE risk and their roles in the development of the diseases need more further researches.

Abstract
Peptidylarginine deiminases (PADs) catalyze citrullination, a post-translational modification playing a pathogenic role in anti-citrullinated protein antibody (ACPA)-positive rheumatoid arthritis (RA). The interplay between single nucleotide polymorphisms (SNPs) in the PADI genes and known risk factors for ACPA-positive RA, including smoking, HLA-DR4 and -1, and the PTPN22 R620W polymorphism, was investigated. We typed four PADI2 SNPs, four PADI4 SNPs, and the PTPN22 R620W SNP in 445 Danish RA patients and 533 age-matched healthy controls, as well as in 200 North American RA patients and 100 age- and sex-matched controls. The HLA-DRB1 locus was typed in the Danish cohort. Logistic regression analyses, adjusted for age, sex, smoking status, and PTPN22 R620W, revealed increased risk of anti-CCP-positive RA in carriers of rs11203367(T) (OR: 1.22, p=0.03) and reduced risk in carriers of rs2240335(A) in PADI4 (OR: 0.82, p=0.04). rs74058715(T) in PADI4 conferred reduced risk of anti-CCP-negative RA (OR: 0.38, p=0.003). In HLA-DRB1*04-positive individuals, specifically, the risk of anti-CCP-positive RA was increased by carriage of PADI4 rs1748033(T) (OR: 1.54, p=0.007) and decreased by carriage of PADI4 rs74058715(T) (OR: 0.44, p=0.01), and we observed an interaction between these SNPs and HLA-DRB1*04 (p=0.004 and p=0.008, respectively) Thus, PADI4 polymorphisms associate with ACPA-positive RA, particularly in HLA-DRB1*04-positive individuals, and with ACPA-negative RA independently of HLA-DRB1*04.

Abstract
BACKGROUND Rheumatoid arthritis (RA) and periodontitis (PD) are proven to share common risk markers, including genetic factors. In the present study we focused on genetic variants in PTPN22 (rs2476601), PADI4 (rs2240340), CTLA4 genes (rs3087243) and its impact on RA and PD. MATERIALS AND METHODS In the study 111 RA patients and 256 systemically healthy controls were involved. A subdivision of patients and controls was carried out according the severity of periodontitis (no/level 1 PD vs. level 2 PD). RESULTS I. Evaluating the genetic impact on the occurrence of RA the T allele of rs2476601 (PTPN22) (bivariate: p < 0.001; multivariate: p = 0.018) and T allele of rs2240340 (PADI4) (bivariate: p = 0.006; multivariate: p = 0.070) were associated with an increased vulnerability to RA. II. Investigating the genetic influence on level 2 PD the T allele of rs2476601 (PTPN22) was shown to be associated with a higher susceptibility to PD within the RA group (bivariate: p = 0.043; multivariate: p = 0.024). III. The T allele of rs2476601 (PTPN22) was proven to be a significant marker of RA and level 2 PD comorbidity (bivariate: p < 0.001; multivariate: p = 0.028). CONCLUSIONS These results support the thesis that genetic variations may represent a possible link between PD and RA. The study increases knowledge about disease-specific and cross-disease genetic pattern.

Abstract
Rheumatoid arthritis (RA) is an inflammatory polyarthritis that typically affects the small joints but can also involve the manubriosternal joint (MSJ). Although cases of MSJ involvement in RA are rare, such cases present with chest pain, a mass-like lesion, and subluxation. These cases can also be diagnosed incidentally, while patients are asymptomatic. It is important to differentiate RA involving the MSJ from other diseases such as ankylosing spondylitis that can affect the MSJ. Several cases of RA affecting the MSJ have been reported in Western countries, but none have been reported to date in Asia, especially with disease activity of RA. Here, we report a case of RA in the MSJ that was confirmed by imaging and histological investigation in a middle-aged Asian woman.

Abstract
Vitamin D is involved in immune system modulation as well as in calcium and bone homeostasis, hence plays a role in rheumatoid arthritis (RA) etiopathogenesis. A bulk of studies in different populations have assessed the association between the vitamin D receptor (VDR) gene polymorphisms and the risk of RA, reporting conflicting results. Therefore, we designed a meta-analysis to comprehensively evaluate the association of VDR gene polymorphisms and RA risk. All potential studies reporting the association between VDR gene polymorphisms and susceptibility to RA published till February 2020 were retrieved through systematic search of database, including Scopus and MEDLINE. Strength of pooled association was determined through calculating the pooled odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup analysis was performed by stratifying the studies by population type. This meta-analysis included 23 eligible studies (21 articles) overall. We noticed that FokI SNP had a significant protective association with susceptibility to RA in the overall analysis as well as in Europeans and Asians. TaqI SNP decreased the RA risk in Africans and Arabs, but not in the overall analysis. Likewise, BsmI SNP and RA risk in the overall population analysis was not significant. Interestingly, BsmI polymorphism increased RA risk in Africans. This meta-analysis offers a significant association between VDR gene polymorphism and susceptibility to RA in both overall and ethnic-specific analysis. However, different polymorphisms acted inversely in increasing or decreasing RA risk in different populations.

Abstract
BACKGROUND Certain single nucleotide polymorphisms (SNPs) in genes such as PADI4 (coding for peptidyl arginine deiminase 4), PDCD1 (coding for programmed cell death 1), and CTLA4 (coding for cytotoxic T-lymphocyte-associated protein 4) are linked to rheumatoid arthritis (RA). However, links between SNPs rs2240340, rs10204525 and rs231775 in PADI4, PDCD1 and CTLA4 respectively, and juvenile idiopathic arthritis (JIA), the commonest type of childhood arthritis, are unclear. We aimed to determine whether any of these SNPs are associated with JIA, and to clinical indices disease activity score (JADAS 71) and functional disability score (CHAQ). METHODS We genotyped the three SNPs in 150 children with polyarticular JIA and 160 healthy children, recording standard health questionnaires, clinical features and laboratory markers. RESULTS The TT genotype of PADI4 rs2240340 (aOR/95%CI 2.64: 1.31-5.30, P = 0.006) and CT genotype of PDCD1 rs10204525 (aOR/95%CI 4.99: 2.98-8.36, P < 0.0001) were associated with JIA. The AG+GG genotype of CTLA4 rs231175 was modestly linked to disease activity (aOR/95%CI 2.44 (1.19-5.04), p = 0.015). PADI4 rs2240340 was linked to CHAQ score (genotypes p = 0.013, alleles p = 0.006), whilst PDCD1 rs10204525 was linked to anti-CCP antibodies (genotypes p = 0.004), RF (genotypes p = 0.01), and the CHAQ score (genotypes p = 0.005, alleles p = 0.013). CONCLUSIONS There are various roles for these SNPs in PADI4, CTLA4 and PDCD1 in the diagnosis and, potentially, in the management of JIA.

Abstract
OBJECTIVE To assess the relative efficacy and safety of apremilast, secukinumab, and ustekinumab at different doses in patients with active psoriatic arthritis (PsA). METHOD A Bayesian network meta-analysis was conducted, which included randomized controlled trials (RCTs) that examined the efficacy and safety of apremilast 20 mg, apremilast 30 mg, secukinumab 75 mg, secukinumab 150 mg, secukinumab 300 mg, ustekinumab 45 mg, and ustekinumab 90 mg compared with placebo. RESULTS Of the RCTs 8 comprising 3289 patients met the inclusion criteria. The American College of Rheumatology (ACR) 20 response rate was significantly higher in the secukinumab 300 mg group than in the placebo group (odds ratio OR, 7.55; 95% confidence interval CI, 3.18-17.63). Secukinumab 150 mg, secukinumab 75 mg, ustekinumab 90 mg, apremilast 30 mg, apremilast 20 mg, and ustekinumab 45 mg were also more efficacious than placebo. There were no significant differences in the efficacy between the interventions. A dose-response relationship among the same drug groups was observed. The number of serious adverse events was not significantly different among the apremilast, secukinumab, ustekinumab, and placebo groups. CONCLUSION All drug treatments were more efficacious than placebo; however, there were no significant differences in the efficacy and safety between the drugs at the different doses.

Abstract
OBJECTIVE We aimed to evaluate the relationship between circulating blood adipokine levels and systemic sclerosis (SSc). METHODS We conducted a meta-analysis on serum/plasma adiponectin, leptin, or resistin levels in patients with SSc and controls, and performed a subgroup analysis based on ethnicity and/or disease type. RESULTS Eleven studies (511 patients with SSc and 341 controls) were included in the meta-analysis. Meta-analysis revealed that adiponectin levels were significantly lower in patients with SSc than in controls (standardized mean differences [SMD] = -0.638; 95 % confidence intervals [CI] = -1.154, -0.122; P = 0.015). Stratification by ethnicity showed a low adiponectin level associated with SSc in Caucasians (SMD = -0.439; 95 % CI = -1.092, -0.213; P = 0.187) and Asians (SMD = -1.006; 95 % CI = -2.031, -0.019; P = 0.055), although this result was not statistically significant. Stratification by disease type revealed that the adiponectin level was significantly lower in the diffuse SSc, but not limited SSc, group than in the control (diffuse: SMD = -1.445; 95 % CI = -2.276, -0.614; P = 0.001; limited: SMD = 0.188; 95 % CI = -0.064, 0.439; P = 0.144). Meta-analysis showed no association between leptin levels and SSc (SMD = -0.029; 95 % CI = -1.362, 1.304; P = 0.966), and no association between resistin levels and SSc (SMD = 0.202; 95 % CI = -0.091, 0.496; P = 0.177). CONCLUSIONS Our meta-analysis revealed a significantly lower circulating adiponectin level in patients with SSc than in controls. This difference was apparent in the diffuse type of SSc, but not in the limited type. However, circulating leptin and resistin levels were not different between patients with SSc and healthy controls.

Abstract
OBJECTIVE The aim of this study was to determine whether the brain-derived neurotrophic factor ( BDNF) 196 G/A or catechol- O-methyltransferase ( COMT) Val158Met polymorphisms is associated with susceptibility to ADHD. METHOD We conducted a meta-analysis of the associations between the BDNF 196 G/A and COMT Val158Met polymorphisms and ADHD. RESULTS Sixteen studies consisting of 3,594 patients with ADHD and 4,040 controls were included in this meta-analysis. Our results showed no association between ADHD and the BDNF 196A allele in all participants (odds ratio [OR] = 0.958, 95% confidence interval [CI] = [0.800, 1.146], p = .638), European or Asian population. Meta-analysis indicated no association between ADHD and the COMT G allele in all study participants (OR = 1.078, 95% CI = [0.962, 1.207], p = .196), European or Asian population. CONCLUSION This meta-analysis showed a lack of association between the BDNF 196 G/A and COMT Val158Met polymorphisms and ADHD.

Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory disease of synovial joints, characterized by the presence of the highly disease-specific anti-citrullinated protein antibodies (ACPA) in approximately 70% of patients. Epstein-Barr virus (EBV) has previously been suggested to be involved in the pathophysiology of RA. However, given the high incidence of EBV in the general population and the difficulty of detecting initial infection, providing a direct link between EBV infection and RA development has remained elusive. We hypothesized that primary EBV infection may be a trigger for the development of the ACPA response in vivo. Using a unique cohort of 26 kidney transplant patients with a primary EBV infection, the presence of ACPA before and following infection was determined. No increase in IgG anti-CCP2 titers was detected following EBV infection. IgG anti-CCP2 antibodies were present in two patients and borderline positive in another. These three patients were HLA-DR4 negative. To test whether EBV infection may trigger a non-class switched anti-CCP2 response, IgM anti-CCP2 antibodies were analyzed. No general trend in the IgM anti-CCP2 response was observed following EBV infection. Since two out of the three IgG anti-CCP2 (borderline) positive patients were diagnosed with IgA nephropathy, 23 additional IgA nephropathy patients were tested for IgG anti-CCP2, regardless of their EBV status. All of these patients were IgG anti-CCP2 negative, indicating that IgG anti-CCP2 is not commonly present in IgA nephropathy patients. Collectively, these data do not support the hypothesis that EBV does trigger the highly RA specific ACPA response.

Abstract
The cause and pathogenesis of rheumatoid arthritis (RA) are influenced by environmental and genetic risk factors. Shared epitope-coding human leukocyte antigen (HLA)-DRB1 alleles increase RA risk and severity; however, the underlying mechanisms of action remain unclear. In contrast, several other DRB1 alleles protect against RA. Additionally, genome-wide association studies suggest that RA associates with other, HLA and non-HLA, genes; but the relative contributions of such risk loci to RA are incompletely understood. Future research challenges include integrating the epidemiologic and genomic data into validated arthritogenic pathways and determining the mechanisms of interaction between RA risk genes and environmental influences.

Abstract
Background Many studies have analyzed the association between peptidylarginine deiminase 4 (PADI4) -104C/T polymorphism and rheumatoid arthritis (RA). However, the results are inconsistent. This meta-analysis, based on different populations, updated and reevaluated the possible associations between PADI4 -104C/T polymorphism and the susceptibility to RA. Methods A literature search was performed on PubMed and related Chinese databases up to April 2017. The association between PADI4 -104C/T polymorphism and RA risk was evaluated by calculating pooled odds ratios (ORs) and 95% confidence intervals (CIs). Results A total of seventeen studies, including 5,756 RA cases and 4,987 controls, were screened out. In the overall population, PADI -104C/T polymorphism was significantly associated with an increased RA risk. In this meta-analysis stratified by ethnicity, a significant association between PADI -104C/T polymorphism and RA risk was established in China and Japan. Conclusions Our study indicated a significantly increased association between PADI -104C/T polymorphism and RA in Chinese and Japanese populations. Because most included populations in this meta-analysis were Asian, further studies are needed to elucidate whether the PADI4 -104C/T gene confers RA in other ethnic groups.

Abstract
BACKGROUND Behçet disease (BD) is a chronic inflammatory disease. Adipokines are synthesized in adipose tissue, and have been reported to play important roles in the pathogenesis of autoimmune and inflammatory diseases, including BD. AIM To evaluate the relationship between circulating blood adipokine levels and BD. METHODS We conducted a meta-analysis of papers reporting on serum/plasma resistin, leptin, adiponectin and visfatin levels in patients with BD and in healthy controls (HCs). We identified 82 relevant studies using electronic and manual search methods, and selected 16 studies for full-text review based on the title and abstract. Two of these were later excluded (one was a review, one had no data), leaving 14 articles that met the inclusion criteria for this meta-analysis. RESULTS The 14 included studies assessed 637 patients with BD and 520 HCs. Compared with the HCs, the BD group had significantly higher levels of leptin [standardized mean difference (SMD) = 0.68, 95% CI 0.15-1.21, P = 0.01]. Levels of resistin (SMD = 0.51, 95% CI 0.92-0.918, P = 0.02) and adiponectin (SMD = 0.31, 95% CI 0.06-0.56, P = 0.02) were significantly higher in the BD group after adjustment for age, sex and body mass index (BMI), but not without such adjustment (resistin: (SMD = 0.38, 95% CI -0.18 to 0.93, P = 0.19; adiponectin: SMD = -0.59, 95% CI -2.23 to 1.06, P = 0.48). A significantly lower visfatin level was found in the BD group with adjustment (SMD = -1.70, 95% CI -2.14 to -1.25, P < 0.001) but not without adjustment (SMD = 0.31, 95% CI -0.21 to 0.82, P = 0.24). CONCLUSIONS Our meta-analysis revealed significantly higher circulating resistin, leptin and adiponectin levels and lower visfatin levels in patients with BD than in HCs, indicating that adipokines probably play an important role in BD pathogenesis.

Abstract
OBJECTIVE The aim of the present study was to determine whether polymorphisms of the endothelial nitric oxide synthase (eNOS) gene are associated with susceptibility to osteonecrosis of the femoral head (ONFH). METHODS We conducted a meta-analysis to assess the association between the 4b/a, G894T, and T786C polymorphisms of eNOS and the susceptibility to ONFH. RESULTS A total of five studies, which included 566 cases and 833 controls, were included in the meta-analysis. Meta-analysis revealed a significant association between allele a of the 4b/a polymorphism and ONFH in all study subjects (odds ratio, OR 3.237; 95 % confidence interval, CI 2.036-5.148; P = 6.9 × 10-7); stratification by ethnicity indicated an association between this allele and ONFH in Caucasians and Asians (OR 2.985; 95 % CI 1.592-5.597; P = 0.001 and OR 3.567; 95 % CI 1.793-7.095; P = 2.9 × 10-4, respectively). Meta-analysis stratified by ONFH type showed a significant association between allele a of the 4b/a polymorphism and idiopathic and secondary ONFH (OR 3.411; 95 % CI 2.049-5.679; P = 2.4 × 10-6 and OR 3.163; 95 % CI 1.781-5.619, P = 8.6 × 10 -5, respectively). However, the meta-analysis did not show any allelic association between the G894T and T786C polymorphisms and ONFH (OR 1.718; 95 % CI 0.796-3.707; P = 0.168 and OR 1.027; 95 % CI 0.191-5.517; P = 0.976, respectively). CONCLUSION Our meta-analysis of published studies shows that the 4b/a polymorphism is associated with the development of idiopathic and secondary ONFH in Caucasians and Asians.

Abstract
OBJECTIVE The aim of this study was to determine whether polymorphisms in solute carrier family 2 and facilitated glucose transporter member 9 (SLC2A9) are associated with susceptibility to gout. METHODS A meta-analysis was conducted on associations between the rs12510549, rs16890979, and rs1014290 polymorphisms of SLC2A9 and gout susceptibility using fixed and random effects models. RESULTS Eleven comparative studies comprising 1,472 patients and 3,269 controls from Caucasian and Asian populations were included in this meta-analysis. The meta-analysis identified a significant negative association between gout and allele 2 (minor) of the rs12510549 polymorphism in the overall population (OR = 0.641, 95 % CI = 0.540-0.761, P = 4.1 × 10-7). Stratification by ethnicity identified a significant negative association between this polymorphism and gout in Caucasians (OR = 0.647, 95 % CI = 0.542-0.771, P = 1.2 × 10-6) but not in Asians (OR = 0.515, 95 % CI = 0.214-1.236, P = 0.137). The meta-analysis showed a significant negative association between gout and allele 2 of the rs16890979 polymorphism in all study subjects (OR = 0.229, 95 % CI = 0.084-0.628, P = 0.004). Stratification by ethnicity identified a significant negative association between this polymorphism and gout in Caucasians (OR = 0.469, 95 % CI = 0.317-0.695, P = 1.6 × 10-6) and in Asians (OR = 0.192, 95 % CI = 0.072-0.513, P = 0.001). A significant negative association was found between allele 2 of the rs1014290 polymorphism and gout susceptibility in Asians (OR = 0.597, 95 % CI = 0.478-0.746, P = 5.4 × 10-6) but not in Caucasians (OR = 0.778, 95 % CI = 0.595-1.043, P = 0.095). CONCLUSIONS This meta-analysis shows that the rs12510549, rs16890979, and rs1014290 polymorphisms of SLC2A9 protect against the development of gout in Caucasians and/or Asians.

Abstract
Studies have shown that the genetic risk factors for rheumatoid arthritis (RA) differ substantially between Asian and Caucasian populations. Even among Asian populations, the genetic contributions of NLRP1, PTPN22 and PADI4 have been controversial. Consequently, we sought to address these separate findings and determine whether any of these proposed risk variants are associated with RA susceptibility, onset, DAS activity and erosion in a Singaporean Chinese cohort. We genotyped five SNPs within NLRP1 (rs878329 and rs6502867), PTPN22 (rs2488457 and rs6665194), and PADI4 (rs2240340) in 500 anti-cyclic citrullinated peptide antibody-positive (ACPA) patients with RA and 500 healthy controls using TaqMan assays. The CC genotype of NLRP1 rs878329 and TT genotype of PADI4 rs2240340 were associated with RA susceptibility. The risk association of the T allele of PADI4 rs2240340 with RA was confirmed through a meta-analysis based on previous reports in Asian populations. The GG genotype of PTPN22 rs6665194 (-3508A>G) was associated with significantly reduced risk of RA. No significant association was found for NLRP1 rs6502867 T/C and PTPN22 rs2488457 G/C polymorphisms. None of the five SNPs was associated with RA's clinical features. This work supports the association of the T allele of PADI4 rs2240340 with RA in Asians. The roles of NLRP1 rs878329 G/C and PTPN22 rs6665194 A/G polymorphisms were demonstrated for the first time. We also propose rs6665194 to be a promising candidate for RA risk evaluation between ethnicities.

Abstract
OBJECTIVE The aim of this study was to investigate whether the C3435T polymorphism in the gene encoding multidrug resistance protein 1 (ABCB1) can predict responsiveness to or toxicity of disease-modifying antirheumatic drugs (DMARDs) in patients with rheumatoid arthritis (RA). METHODS We conducted a meta-analysis of studies on the association between the ABCB1 C3435T polymorphism and nonresponsiveness to or toxicity of DMARDs in RA patients, using the PUBMED and EMBASE electronic citation databases. Subsequent inclusion/exclusion procedures were performed and then data were extracted for association analysis. RESULTS A total of 14 comparison studies from 9 articles met our inclusion criteria. This final group comprised 4 studies containing data on associations between the ABCB1 C3435T polymorphism and RA susceptibility, 5 studies on the response to DMARDs, and 5 on toxicity of DMARDs in RA patients according to ABCB1 polymorphism status. Meta-analysis revealed no association between RA susceptibility and the ABCB1 C3435T polymorphism [odds ratio (OR) for the T allele = 0.948, 95 % confidence interval (CI) 0.756-1.189, p = 0.645]. Meta-analysis showed no association between the ABCB1 C3435T T allele and a nonresponse to DMARD therapy (OR 0.952, 95 % CI 0.516-1.685, p = 0.817). Stratification by DMARD type indicated no association between the ABCB1 C3435T T allele and nonresponse to methotrexate (MTX) treatment (OR 1.201, 95 % CI 0.456-3.164, p = 0.711). However, the analysis did indicate that MTX toxicity was associated with the ABCB1 C3435T polymorphism in RA under an overdominant model (TC vs. TT + CC; OR 0.483, 95 % CI 0.259-0.900, p = 0.022), evidencing a lower risk of MTX toxicity for heterozygotes (TC) than homozygotes (TT and CC). CONCLUSION This meta-analysis demonstrated that the ABCB1 C3435T polymorphism may be not associated with responsiveness to DMARD therapy, but may be associated with MTX toxicity in RA.

Abstract
OBJECTIVE The purpose of this study was to evaluate the diagnostic performance of 18F-fluorodeoxyglucose positron-emission tomography (18F-FDG PET) or positron-emission tomography/computed tomography (PET/CT) for patients with large vessel vasculitis. METHODS Based on a search in the PubMed, Embase, and Cochrane Library databases, a meta-analysis was performed on the diagnostic accuracy of 18F-FDG PET or PET/CT in patients with large vessel vasculitis. RESULTS A total of eight studies involving 400 subjects (170 vasculitis patients and 230 controls) were selected for meta-analysis. The pooled sensitivity and specificity of 18F-FDG PET or PET/CT were 75.9 % (95 % confidence interval, CI 68.7-82.1) and 93.0 % (95 % CI 88.9-96.0), respectively. The positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnostic odds ratio (DOR) were 7.267 (95 % CI 3.707-14.24), 0.303 (95 % CI 0.229-0.400), and 32.04 (95 % CI 13.08-78.45), respectively. The area under the curve (AUC) was 0.863 and the Q* index 0.794, indicating good diagnostic accuracy. There was no evidence of a threshold effect (Spearman's correlation coefficient = 0.120, p = 0.776). When the data were limited to giant cell arteritis (GCA), the pooled sensitivity and specificity of 18F-FDG PET or PET/CT were 83.3 % (95 % CI 72.1-91.4) and 89.6 % (95 % CI 79.7-95.7), respectively; AUC was 0.884, and the Q* index 0.815, indicating modest accuracy with a small increase in diagnostic accuracy. CONCLUSION This meta-analysis of published studies demonstrates that 18F-FDG PET or PET/CT has good diagnostic accuracy for large vessel vasculitis and plays an important role in the diagnosis of this condition.

Abstract
AIMS This study aimed to assess the relative efficacy and tolerability of etoricoxib, celecoxib, and naproxen at recommended dosages in patients with osteoarthritis (OA). METHODS Randomized controlled trials (RCTs) examining the efficacy and tolerability of etoricoxib 30-60 mg, celecoxib 200-400 mg, and naproxen 1000 mg, based on the number of patient withdrawals among those with OA, were included in this network meta-analysis. We performed a Bayesian random-effects network meta-analysis to combine direct and indirect evidence from the RCTs. RESULTS Eight RCTs, including 5,942 patients, met the inclusion criteria. The proportion of patient withdrawals due to lack of efficacy was significantly lower in the etoricoxib 30-60 mg (OR 0.21, 95 % CrI 0.12-0.38), celecoxib 200-400 mg (OR 0.29, 95 % CrI 0.18-0.47), and naproxen 1000 mg (OR 0.31, 95 % CrI 0.18-0.51) groups than in the placebo group. The number of patient withdrawals due to lack of efficacy tended to be lower in the etoricoxib 30-60 mg group than in the naproxen 1000 mg and celecoxib 200-400 mg groups, although they did not reach statistical significance (OR 0.68, 95 % CrI 0.36-1.33 and OR 0.70, 95 % CrI 0.38-1.37, respectively). Ranking probabilities based on the surface under the cumulative ranking curve (SUCRA) indicated that etoricoxib 30-60 mg had the highest probability of being the best treatment based on the number of withdrawals due to lack of efficacy (SUCRA = 0.9168) followed by celecoxib 200-400 mg (SUCRA = 0.5659), naproxen 1000 mg (SUCRA = 0.5171), and placebo (SUCRA = 0.000189). With respect to tolerability, the number of withdrawals due to adverse events was not significantly different among etoricoxib, celecoxib, naproxen, and placebo, although it tended to be lower with etoricoxib and placebo. CONCLUSIONS Etoricoxib 30-60 mg, celecoxib 200-400 mg, and naproxen 1000 mg were more efficacious than placebo. However, there was no significant difference in efficacy and tolerability between the medications.

Abstract
OBJECTIVE This study aimed to evaluate the relationship between the circulating serum leptin level and rheumatoid arthritis (RA) and to establish a correlation between serum leptin levels and RA activity. METHODS We searched the PUBMED, EMBASE, and Cochrane databases. A meta-analysis was performed, comparing the serum/plasma leptin levels in patients with RA and healthy controls. Correlation coefficients between serum leptin level and either disease activity score 28 (DAS28) or C‑reactive protein (CRP) in RA patients were also examined. RESULTS Thirteen studies with a total of 648 RA patients and 426 controls were included in this meta-analysis. Circulating leptin level was significantly higher in the RA group than in the control group (SMD = 1.056, 95 % CI = 0.647-1.465, p = 4.2 × 10-7). In addition, stratification by ethnicity showed a significantly elevated leptin level in the RA group in Caucasian, Turkish, and Arab populations (SMD = 0.813, 95 % CI = 0.137-1.490, p = 0.018, SMD = 0.981, 95 % CI = 0.307-1.655, p = 0.004, and SMD = 1.469, 95 % CI = 0.443-2.495, p = 0.005 respectively). A meta-analysis of correlation coefficients showed a small but significantly positive correlation between the circulating leptin level and either DAS28 (correlation coefficient = 0.275, 95 % CI = 0.076-0.452, p = 0.007) or CRP (correlation coefficient = 0.274, 95 % CI = 0.068-0.458, p = 0.010). CONCLUSIONS Our meta-analysis demonstrated that the circulating leptin level is significantly higher in patients with RA and that a small but significantly positive correlation exists between leptin levels and RA activity.

Abstract
Objective This study aimed to evaluate the relationship between circulating prolactin level and systemic lupus erythematosus (SLE), and to establish a correlation between plasma/serum prolactin levels and SLE activity. Methods We performed a meta-analysis comparing the plasma/serum prolactin levels in patients with SLE to controls, and examined correlation coefficients between circulating prolactin level and SLE disease activity. Results Twenty-five studies with a total of 1056 SLE patients and 426 controls were included. Prolactin levels were significantly higher overall in the SLE group than in the control group (standardized mean difference (SMD) = 0.987, 95% CI = 0.512–1.463, p = 4.7 × 10−5). Stratification by ethnicity showed significantly elevated prolactin levels in the SLE group in Asian, Latin American, and mixed populations (SMD = 0.813, 95% CI = 0.137–1.490, p = 0.018; SMD = 0.981, 95% CI = 0.307–1.655, p = 0.004; SMD = 1.469, 95% CI = 0.443–2.495, p = 0.005, respectively), but not in the European population. Subgroup analysis by sample size showed significantly higher prolactin levels in the SLE group by small ( n < 30) and large sample numbers ( n > 30). Meta-analysis of correlation coefficients showed a significantly positive correlation between circulating prolactin level and SLE activity (correlation coefficient = 0.379, 95% CI = 0.026–0.487, p = 4.0 × 10−9). Circulating prolactin levels were positively associated with SLE activity in European, Asian, and mixed populations (SMD = 0.532, 95% CI = 0.443–0.609 p < 1.0 × 10−8; SMD = 0.427, 95% CI = 0.240–0.583, p = 2.4 × 10−5; SMD = 0.433, 95% CI = 0.212–0.591, p = 2.7 × 10−5, respectively). Conclusions Our meta-analysis demonstrated that circulating prolactin levels are higher in patients with SLE, and that a significantly positive correlation exists between prolactin levels and SLE activity.

Abstract
The aim of this study was to perform a meta-analysis of eligible studies and to derive a precise estimate of the association between interleukin 10 (IL10) polymorphisms and susceptibility to autoimmune thyroid disease (AITD). Meta-analyses were conducted on the associations between AITD and the -1082 G/A (rs1800896), -819 C/T (rs1800871) and -592 C/A (rs1800872) polymorphisms in IL10, and the haplotype of these polymorphisms and AITD. A total of 2903 AITD patients and 3060 controls in 10 eligible studies were included in the meta-analysis. This meta-analysis showed significant associations between IL10 at the -1082 G allele and overall AITD (OR: 1.44, 95% CI 1.13-1.82, P = 0.003), but no association between the IL10 -592 C allele and the -819 C allele and AITD. Subgroup studies demonstrated significant associations between the -1082 G allele and susceptibility to Graves' disease. Ethnicity-specific meta-analysis revealed significant associations between the -1082 G allele and AITD susceptibility in Asian populations; however, in Middle Eastern populations, no association was evident. Meta-analysis of the IL10 haplotype revealed an association between the ATA haplotype and AITD (OR: 1.17, 95% CI 1.00-1.36, P = 0.04). Meta-analysis demonstrates that the IL10 polymorphisms are associated with susceptibility to AITD.

Abstract
OBJECTIVE The purpose of this study was to compare the diagnostic performance of anti-mutated citrullinated vimentin (anti-MCV) and anti-cyclic citrullinated peptide (anti-CCP) antibodies in rheumatoid arthritis (RA). METHODS We searched the Medline, Embase, and Cochrane library databases and performed two meta-analyses on the diagnostic accuracy of anti-MCV and anti-CCP in patients with RA compared to healthy controls. RESULTS We identified 12 studies that included a total of 2003 RA patients and 831 healthy controls for the meta-analysis. The pooled sensitivity and specificity of anti-MCV were 68.6% [95% confidence interval (CI) 66.6-79.7] and 94.2% (95% CI 92.4-96.7) and those of anti-CCP were 61.7% (95% CI 59.5-63.8) and 97.1% (95% CI 96.7-98.1), respectively. Anti-MCV PLR, NLR, and DOR were 12.99 (95% CI 8.013-21.27), 0.297 (95% CI 0.238-0.369), and 47.78 (95% CI 28.59-79.84), and those for anti-CCP were 16.71 (95% CI 11.42-24.47), 0.378 (95% CI 0.325-0.439), and 54.20 (95% CI 31.65-92.82), respectively. The AUC of anti-MCV was 0.886, and its Q* index was 0.817, indicating modest accuracy, while the AUC of anti-CCP was 0.946, and its Q* index was 0.885. The sensitivity of anti-MCV was significantly higher than that of anti-CCP in the diagnosis of RA (difference 0.069, 95% CI 0.039-0.098, p < 0.0001), but the specificity of anti-MCV was lower than that of anti-CCP (difference -0.029, 95% CI -0.051 to -0.006, p = 0.012). The Q* index of anti-MCV was significantly lower than that of anti-CCP (difference -0.068, 95% CI -0.070 to -0.065, p < 0.0001). CONCLUSION Our meta-analysis demonstrates that anti-MCV is more sensitive but less specific, and has lower diagnostic accuracy than anti-CCP in RA, although anti-MCV and anti-CCP showed comparable high PLRs.

Abstract
Epidemiological studies have linked periodontitis to rheumatoid arthritis (RA). Porphyromonas gingivalis (Pg) was reported recently to produce citrullinated protein (CP) and increase anti-cyclic CP antibody (ACPA), both of which have been identified as causative factors of RA. In the present study, we determined the effects of Pg infection on the exacerbation of RA in a mouse model. RA model mice (SKG mice) were established by an intraperitoneal (i.p.) injection of laminarin (LA). Mice were divided into six groups, Ctrl (PBS injection), LA (LA injection), Pg/LA (Pg + LA injection), Pg (Pg injection), Ec/LA (Escherichia coli and LA injection) and Ec (E. coli injection). In order to evaluate RA, joint swelling by the arthritis score, bone morphology by microcomputed tomography (microCT), haematoxylin and eosin staining, ACPA, matrix metalloproteinase-3 (MMP-3) and cytokine level in serum by enzyme-linked immunosorbent assay were determined. Osteoclast differentiation from bone marrow mononuclear cells (BMCs) was examined to clarify the underlying mechanisms of RA. The presence of Pg and CP in joint tissue was also investigated. The arthritis score was threefold higher in the Pg/LA group than in the LA group. Severe bone destruction was observed in joint tissue of the Pg/LA group. A microCT analysis of the Pg/LA group revealed a decrease in bone density. ACPA, MMP-3, interleukin (IL)-2, IL-6, CXCL1 and macrophage inflammatory protein (MIP)-1α levels from the Pg/LA group were the highest. The osteoclastogenesis of BMCs was enhanced in the Pg/LA group. Furthermore, large amounts of Pg components and CP were detected in the Pg/LA group. In conclusion, Pg infection has the potential to exacerbate RA.

Abstract
Aim: The aim of the current study was to investigate whether FCGR polymorphisms are associated with responsiveness to anti-TNF-α therapy in patients with spondyloarthropathy, psoriasis, and Crohn's disease. Materials & methods: We conducted a meta-analysis to evaluate the association between the functional FCGR3A F158V and FCGR2A R131H polymorphisms and responsiveness to TNF blockers. Results: The meta-analysis indicated that responsiveness to TNF blockers was associated with the FCGR3A V allele (odds ratio: 3.308; 95% CI: 1.053–10.39; p = 0.040) and the FCGR2A RR + RH genotype (odds ratio: 3.904; p = 0.027) in patients with a follow-up time of ≥6 months. Conclusion: FCGR3A V and FCGR2A R allele carriers show better responsiveness to anti-TNF-α therapy in patients with follow-up times ≥6 months.

Abstract
Objective This study aimed to explore whether TYK2 polymorphisms are associated with susceptibility to autoimmune rheumatic diseases. Methods We conducted a meta-analysis on the association between TYK2 polymorphisms and autoimmune rheumatic diseases. Results Twelve studies with a total of 16,335 patients and 30,065 controls were included in the meta-analysis. Meta-analysis revealed an association between rheumatic diseases and the 2 allele of the TYK2 rs2304256 (OR = 0.885, 95% CI = 0.802–0.978, p = 0.016). Furthermore, stratification by ethnicity identified a significant association between this polymorphism and rheumatic diseases in Caucasians (OR = 0.822, 95% CI = 0.706–0.889, p = 9.5 × 10−7), but not in Asians (OR = 1.127, 95% CI = 0.835–1.522, p = 0.434). Meta-analysis by rheumatic disease type revealed a significant association between the 2 allele of the TYK2 rs2304256 and SLE in Caucasians (OR = 0.737, 95% CI = 0.673–0.808, p < 1.0 × 10−8) but not in Asians (OR = 1.211, 95% CI = 0.813–1.804, p = 0.347). Meta-analysis revealed that the rs12720356 polymorphism was associated with susceptibility to rheumatic diseases in Caucasians (OR = 0.812, 95% CI = 0.661–0.997, p = 0.046) but not in Asians. Interestingly, the rs280519 polymorphism was significantly associated with susceptibility to SLE both in Caucasians and Asians. However, no associations were found between the rs12720270, rs280500, rs280523 and rs8108236 polymorphisms and susceptibility to rheumatic diseases. Conclusions This meta-analysis demonstrates that the TYK2 rs2304256 and rs12720356 polymorphisms are associated with susceptibility to rheumatic diseases, rs2304256 polymorphism is associated with SLE in Caucasians, and rs280519 polymorphism is associated with SLE in Caucasians and Asians.

Abstract
This study investigated whether the 5-aminoimidazole-4-carboxamide ribonucleotide transformylase gene (ATIC) 347 C/G polymorphism can predict the response to or toxicity of methotrexate (MTX) in patients with rheumatoid arthritis (RA). We conducted a meta-analysis of studies on the association between ATIC 347 C/G polymorphism and non-responsiveness to or toxicity of MTX in RA patients, using PUBMED, EMBASE, and COCHRANE. Nine comparative studies from 6 articles including 1056 RA patients met our inclusion criteria. This final group of studies comprised 5 studies on response to MTX and 4 on toxicity of MTX in RA patients in relation to the ATIC 347 C/G polymorphism status. Meta-analysis showed association between the ATIC 347 GG + GC genotype and non-response to MTX therapy (OR = 1.572, 95 % CI 1.146-2.156, p = 0.005). Stratification by ethnicity indicated significant association between the ATIC 347 GG + GC genotype and non-response to MTX in Caucasians (OR = 1.884, 95 % CI 1.236-2.873, p = 0.003), but not in Asian patients. Similarly, associations were noted for the ATIC 347 C/G polymorphism through analysis using recessive and overdominant models. Meta-analysis revealed association between the ATIC 347 GG + GC genotype and MTX toxicity (OR = 1.454 95 % CI 1.034-2.044, p = 0.032). Stratification by ethnicity indicated significant association between the ATIC 347 GG + GC genotype and MTX toxicity in Caucasians (OR = 1.741, 95 % CI 1.080-2.806, p = 0.023), but not in Asian patients. The ATIC 347 C/G polymorphism may be associated with non-responsiveness to and or toxicity of MTX in Caucasian RA patients.

Eighteen studies (twelve on PTPRC and six on FCGR2A) from eight articles involving 3058 patients were considered in this meta-analysis. The meta-analysis showed a significant association between the PTPRC rs10919563 A allele and response to TNF-α blockers in RA. The OR of the PTPRC A allele was significantly lower in responders (OR = 0.584, 95 % CI = 0.409-0.835, P = 0.003). Meta-analysis revealed no association between the FCGR2A HH + HR genotype and responsiveness to TNF blockers in all study subjects (OR = 0.762, 95 % CI = 0.543-1.068, P = 0.115). However, stratification by TNF inhibitor type showed that the FCGR2A HH + HR genotype was associated with responsiveness to adalimumab (OR = 0.591, 95 % CI = 0.369-0.947, P = 0.029), but not infliximab and etanercept (OR = 0.929, 95 % CI = 0.354-2.440, P = 0.881; OR = 0.804, 95 % CI = 0.293-2.207, P = 0.673). The PTPRC rs10919563 A allele shows a poor response to anti-TNF therapy, and the FCGR2A HH + HR genotype shows a poor response to adalimumab for RA. Genotyping for these polymorphisms may be useful for predicting the response to TNF-α blockers with respect to personalized medicine.

Abstract
OBJECTIVE This study determined whether NLRP3 polymorphisms rs35829419 C/A and rs10754558 C/G were associated with autoimmune and inflammatory diseases. METHODS An association between the NLRP3 rs35829419 C/A and rs10754558 C/G polymorphisms and autoimmune and inflammatory diseases was determined by performing a meta-analysis by using (1) allele contrast, (2) recessive, (3) dominant, and (4) co-dominant models. RESULTS Thirty comparative studies involving 8069 patients and 8824 controls were included in the meta-analysis. No association was observed between autoimmune and inflammatory diseases and NLRP3 rs35829419 C allele (OR = 1.020, 95% CI = 0.804-1.295, p = 0.869). Stratification by ethnicity showed no association between the NLRP3 rs35829419 C allele and autoimmune and inflammatory diseases in European, Latin American, and Polynesian populations. Stratification by disease type showed no association between the NLRP3 rs35829419 C allele and gout, SLE, RA, celiac disease, and Crohn's disease. Moreover, no association was observed between autoimmune and inflammatory diseases and the NLRP3 rs10754558 C allele (OR = 1.057, 95% CI = 0.950-1.177, p = 0.310). However, stratification by ethnicity showed an association between the NLRP3 rs10754558 C allele and autoimmune and inflammatory diseases in the Latin American (OR = 1.399, 95% CI = 1.201-1.630, p = 1.6 × 10-6) but not in European and Asian populations. Further, stratification by disease type showed a significant association of the NLRP3 rs10754558 C allele with SLE (OR = 1.465 95% CI = 1.144-1.875, p = 0.002) but not with gout and celiac disease. The same pattern was observed for the NLRP3 rs10754558 C allele in the recessive model. CONCLUSIONS Our results indicated that the NLRP3 rs10754558 C/G polymorphism was associated with susceptibility to SLE and with autoimmune and inflammatory diseases in Latin American individuals.

Abstract
AIMS This study aimed to assess all-cause and cause-specific standardized mortality ratios (SMRs) in patients with systemic lupus erythematosus (SLE). METHODS We surveyed studies examining all-cause and/or cause-specific SMR in patients with SLE compared to the general population using PUBMED, EMBASE and Cochrane databases and manual searches. We performed a meta-analysis of all-cause, sex-specific, ethnicity-specific, and cause-specific SMRs in SLE patients. RESULTS Fifteen reports including 26,101 patients with SLE with 4640 deaths met the inclusion criteria. Compared to the general population, all-cause SMR was significantly increased 2.6-fold in patients with SLE (SMR 2.663, 95% CI 2.090-3.393, p < 1.0 × 10(-8)). Stratification by ethnicity showed that all-cause SMR was 2.721 (95% CI 1.867-3.966, p = 1.9 × 10(-6)) in Caucasians and 2.587 (95% CI 1.475-4.535, p = 0.001) in Asians. Sex-specific meta-analysis revealed that all-cause SMR was 3.141 (95% CI 2.351-4.198, p < 1.0 × 10(-8)) for women and 3.516 (95% CI 2.928-4.221, p < 1.0 × 10(-8)) for men. The risk of mortality was significantly increased for mortality due to renal disease (SMR 4.689, 95% CI 2.357-9.330, p = 1.10 × 10(-5)), cardiovascular disease (CVD) (SMR 2.253, 95% CI 1.304-3.892, p = 0.004), and infection (SMR 4.980, 95% CI 3.876-6.398, p < 1.0 × 10(-8)), although there was no significant increase in SMR for mortality due to cancer (SMR 1.163, 95% CI 0.572-2.363, p = 0.676). CONCLUSIONS Patients with SLE had higher rates of death from all causes, regardless of sex, ethnicity, renal disease, CVD or infection. However, the risk of death due to malignancy was not increased.

Abstract
OBJECTIVE The aim of this study was to determine whether polymorphisms of the Toll-like receptor (TLR) genes are associated with susceptibility to systemic lupus erythematosus (SLE). METHODS The authors conducted a meta-analysis of the relationship between 12 TLR polymorphisms and SLE susceptibility. RESULTS In total, 26 studies that involved 11,984 patients and 14,572 controls were included in the meta-analysis. The meta-analysis showed no association between the two alleles of the rs352140, rs5743836, and rs352139 polymorphisms of TLR9 and SLE, but indicated an association between the two alleles of the rs187084 polymorphism (TLR9) and SLE in the overall population (OR = 0.869, 95% CI = 0.762-0.992, P = 0.038). No association was detected between rs3764880 (TLR8) and SLE; however, our meta-analysis indicated an association between rs3764879 (TLR8) and SLE in Caucasians (OR = 1.414, 95% CI = 1.139-1.756, P = 0.002). An association between rs179008 (TLR7) and SLE was found in the African (OR = 0.430, 95% CI = 0.238-0.775, P = 0.005), but not in the Caucasian population (OR = 1.206, 95% CI = 0.932-1.614, P = 0.145). Furthermore, our meta-analysis indicated a significant association between rs3853839 (TLR7) and SLE in the Asian population (OR = 0.773, 95% CI = 0.735, 0.823, P < 1.0 × 10(-9)). No associations were found between rs5744168 (TLR5), rs4986791 (TLR4), rs4986790 (TLR4), and rs3775291 (TLR3) polymorphisms and SLE susceptibility. CONCLUSIONS Our meta-analysis suggests that TLR7, TLR8, and TLR9 polymorphisms are associated with the development of SLE in Caucasian, Asian, and African populations.

Abstract
OBJECTIVE The aim of this study was to explore whether the interferon (IFN)-γ +874 T/A polymorphism plays a role in modifying the risk of autoimmune diseases. METHODS A meta-analysis was conducted on the association between the IFN-γ +874 T/A polymorphism and autoimmune diseases. RESULTS Eighteen studies with a total of 2952 patients and 3832 controls were included in the meta-analysis. The meta-analysis revealed no association between autoimmune diseases and the IFN-γ +874 T allele in all study subjects (odds ratio (OR)=1.023, 95% confidence interval (CI) = 0.894-1.171, p = 0.738), but stratification by ethnicity indicated an association between the IFN-γ +874 T allele and autoimmune diseases in Latin American subjects (OR = 0.780, 95% CI = 0.629-0.953, p = 0.015). Meta-analysis also revealed an association between autoimmune diseases and the IFN-γ +874 T/A polymorphism in Caucasian and Middle Eastern subjects under a dominant inheritance model (OR = 0.686, 95% CI = 0.489-0.964, p = 0.003; OR = 1.414, 95% CI = 1.102-1.813, p = 0.006). Meta-analysis by autoimmune disease type indicated an association between ITP and the IFN-γ +874 T allele (OR = 1.753, 95% CI = 1.228-2.503, p = 0.002), but not for vasculitis, vitiligo, and auto-immune thyroid disease. Meta-analysis also showed a significant association between the IFN-γ +874 T/A polymorphism and systemic lupus erythematosus (SLE) under the dominant model (OR = 1.668, 95% CI = 1.114-2.497, p = 0.013). CONCLUSIONS This meta-analysis indicates that the IFN-γ +874 T/A polymorphism may play a significant role in modifying the risk of autoimmune diseases in Caucasian, Latin American, and Middle Eastern subjects, and in particular shows that the IFN-γ +874 T/A polymorphism is associated with increased genetic susceptibility to idiopathic thrombocytopenic purpura and SLE.

Abstract
OBJECTIVE This study determined whether FCGR3B copy number variations (CNVs) were associated with susceptibility to autoimmune diseases. METHODS A meta-analysis was conducted to determine the association between FCGR3B CNVs and susceptibility to autoimmune diseases by comparing low FCGR3B CN (<2 to ≥2) and high FCGR3B CN (>2 to ≤2). RESULTS In all, 28 comparative studies from 15 reports involving 12,160 patients and 11,103 controls were included in this meta-analysis. The meta-analysis showed a significant association between low FCGR3B CN and autoimmune diseases (OR=1.496, 95% CI=1.301-1.716, p=1.0×10(-9)). Subgroup analysis according to ethnicity indicated an association between low FCGR3B CN and autoimmune diseases in Caucasians (OR=1.482, 95% CI=1.219-1.801, p=7.7×10(-6)) and Asians (OR=1.498, 95% CI=1.306-1.717, p=1.0×10(-9)). Meta-analysis according to the type of autoimmune disease indicated a significant association of low FCGR3B CN with systemic lupus erythematosus (SLE; OR=1.797, 95% CI=1.562-2.068, p<1.0×10(-9)), primary Sjogren's syndrome (pSS; OR=2.263, 95% CI=1.316-3.892, p=0.003), and Wegener's granulomatosis (WG; OR=1.973, 95% CI=1.178-3.302, p=0.010), but not with rheumatoid arthritis (RA; OR=1.333, 95% CI=0.947-1.877, p=0.099). However, the meta-analysis showed no association between high FCGR3B CN and SLE, RA, pSS, and WG. CONCLUSIONS Thus, the results of this meta-analysis indicated that low FCGR3B CN increased susceptibility to autoimmune diseases, especially SLE, pSS, and WG.
