Water extracts of Tibetan medicine Wuweiganlu attenuates experimental arthritis via inducing macrophage polarization towards the M2 type. JOURNAL OF ETHNOPHARMACOLOGY 2024; 318:116934. [PMID: 37480967 DOI: 10.1016/j.jep.2023.116934] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/03/2023] [Revised: 07/15/2023] [Accepted: 07/17/2023] [Indexed: 07/24/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Wuweiganlu (WGL) is a well-known formulation described in the "Four Medical Scriptures of Tibetan medicine", which is mainly used for the treatment of Rheumatoid Arthritis (RA) and other chronic ailments prescribed by Tibetan medicine. Nonetheless, the active constituents present in the water extracts of Wuweiganlu (WGLWE) specifically targeting arthritis treatment are largely unknown. AIM OF THE STUDY The aim of this study is to explore the effects and underlying mechanisms of the active components in WGLWE on RA. MATERIALS AND METHODS We utilized ultra-performance liquid chromatography coupled with Q-TOF mass spectrometry (UPLC-Q-TOF-MS) to identify the main chemical compositions of WGLWE. The polarization effect of WGLWE on bone marrow-derived macrophages (BMDM) was determined. A rat model of collagen-induced arthritis (CIA) was established by injecting an emulsion of bovine type II collagen mixed with an equal volume of incomplete Freund's adjuvant into the tail, paw and back of rats. A WGLWE-based ointment was topically applied to the legs and paws of the rats for 30 days. The rats' ankles were photographed to measure the degree of swelling. Micro-CT was used to image the knee joint and paw of rats, and the bone mineral density (BMD) and bone volume fraction (BV/TV) of knee joint in rats were analyzed. High-frequency ultrasound imaging of the rat knee joint was performed to observe knee joint effusion. Further, the serum levels of tumor necrosis factor (TNF-α), interleukin-6 (IL-6), IL-10, and arginine (Arg-1) in CIA rats were detected by enzyme-linked immunosorbent assay (ELISA). Immunohistochemistry (IHC) and immunofluorescence (IF) co-staining were employed to detect the expression levels of inflammatory factors in synovium. RESULTS A total of 28 main components were identified in WGLWE, and these compounds can directly bind to the inflammatory pathway proteins such as JAK2, NFκB and STAT3. In vitro experiments demonstrated that WGLWE promoted the transformation of M1 macrophages into M2 macrophages and suppressed the release of proinflammatory cytokines TNF-α and IL-6. In vivo studies showed that WGLWE effectively reduced ankle swelling, alleviated knee joint effusion, and improved BV/TV while also reducing synovial inflammation levels. Furthermore, WGLWE compounds induced the transition of M1-type macrophages to M2-type macrophages in synovial tissue, resulting in decreased secretion of inflammatory factors TNF-α, WGLWE improved the synovial inflammatory state. CONCLUSION Our results indicated that WGLWE alleviated joint inflammation in CIA rats and the underlying mechanism may be related to inducing the transformation of bone marrow-derived M1 macrophages to M2 macrophages, leading to an increase in the secretion of anti-inflammatory factors and a decrease in pro-inflammatory factors. Therefore, WGLWE may be used as a potential herbal preparation for the treatment of RA.

Abstract
Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease characterized by persistent articular inflammation and joint damage. RA was first described over 200 years ago; however, its etiology and pathophysiology remain insufficiently understood. The current treatment of RA is mainly empirical or based on the current understanding of etiology with limited efficacy and/or substantial side effects. Thus, the development of safer and more potent therapeutics, validated and optimized in experimental models, is urgently required. To improve the transition from bench to bedside, researchers must carefully select the appropriate experimental models as well as draw the right conclusions. Here, we summarize the establishment, pathological features, potential mechanisms, advantages, and limitations of the currently available RA models. The aim of the review is to help researchers better understand available RA models; discuss future trends in RA model development, which can help highlight new translational and human-based avenues in RA research.

Meta-analysis for Association of Interleukin 4 VNTR Polymorphism with Rheumatoid Arthritis Risk and Severity. Biochem Genet 2022; 61:823-846.

Abstract
Rheumatoid Arthritis (RA) is a chronic autoimmune disease characterized by severe joint pain. There are conflicting results for the association of Interleukin 4 (IL4) variable number tandem repeats (VNTR; rs8179190) polymorphism with RA. Therefore, we performed a meta-analysis of the available studies to investigate the association of IL4 VNTR polymorphism with RA risk and severity in the overall populations and Asian, Egyptian, European, and Turkish ethnicities by sub-group analyses. Eight studies involving 1993 RA patients and 1732 controls were included in this meta-analysis. We found increased RA risk for the susceptible "R2R2" genotype and "R2" allele under heterozygous, recessive, and allelic models in the Asian populations (p < 0.00001, p < 0.0001, p = 0.001). We observed a significant association between "R2R2" genotype and "R2" allele for RA protection in the Turkish population under heterozygous, recessive, and allelic models (p = 0.01, p = 0.004, p = 0.002). Disease severity-based analysis revealed significant association for "R2R2" genotype and "R2" allele with RA severity under homozygous, heterozygous, recessive, dominant, and allelic models(p = 0.0004, p = 0.03, p = 0.02, p = 0.003, p = 0.01), specifically in Asian populations (p = 0.009, p = 0.02, p = 0.003, p = 0.03, p = 0.01) and under heterozygous, dominant, and allelic genetic models in Egyptian (p = 0.0001, p < 0.0001, p < 0.0001) and European (p = 0.002, p = 0.0007, p = 0.0006) populations. In silico analysis suggested that the susceptible "R2" allele changes the RNA secondary structure to a stable form by changing minimum free energy(ΔG) from - 115.20 to - 136.40 kcal/mol, which might lead to increased stability of IL-4 in RA patients. Overall, the meta-analysis suggests for the involvement of susceptible "R2" allele with RA risk in the Asian populations, RA severity in the overall populations (specifically in Asian, Egyptian, & European populations), and RA protection in the Turkish population.

Abstract
INTRODUCTION Rheumatoid arthritis (RA) is a chronic systemic disease characterized by articular involvement and extra-articular manifestations. The incidence and prevalence of the disease vary across populations, and there is an ongoing debate on whether a change of RA occurrence over time exists or is due to methodological issues and other biases. Moreover, the disease's onset is related to an interaction of genetic and environmental factors that influence its expression. AREAS COVERED This review explores the latest knowledge on RA epidemiology and the possible risk factors associated with its presentation to identify potential warning signs that may in the future help disease management. EXPERT OPINION Current epidemiological evidence suggests a significant impact of smoking, sex hormones, and lifestyle status in RA occurrence. However, the association between these variables has not yet been thoroughly studied. Still, their effect must be interpreted as they may present subsequently integral indicators for a more rational approach of the disease.

Abstract
Certolizumab pegol (CZP) is a PEGylated Fc-free tumor necrosis factor (TNF) inhibitor antibody approved for use in the treatment of rheumatoid arthritis (RA), Crohn’s disease, psoriatic arthritis, axial spondyloarthritis and psoriasis. In a clinical trial of patients with severe RA, CZP improved disease symptoms in approximately half of patients. However, variability in CZP efficacy remains a problem for clinicians, thus, the aim of this study was to identify genetic variants predictive of CZP response. We performed a genome-wide association study (GWAS) of 302 RA patients treated with CZP in the REALISTIC trial to identify common single nucleotide polymorphisms (SNPs) associated with treatment response. Whole-exome sequencing was also performed for 74 CZP extreme responders and non-responders within the same population, as well as 1546 population controls. No common SNPs or rare functional variants were significantly associated with CZP response, though a non-significant enrichment in the RA-implicated KCNK5 gene was observed. Two SNPs near spondin-1 and semaphorin-4G approached genome-wide significance. The results of the current study did not provide an unambiguous predictor of CZP response.

Abstract
Rheumatoid arthritis (RA) is one of the most frequent inflammatory rheumatic diseases, having a considerably increased prevalence of mortality and morbidity due to cardiovascular disease (CVD). RA patients have an augmented risk for ischemic and non-ischemic heart disease. Increased cardiovascular (CV) risk is related to disease activity and chronic inflammation. Traditional risk factors and RA-related characteristics participate in vascular involvement, inducing subclinical changes in coronary microcirculation. RA is considered an independent risk factor for coronary artery disease (CAD). Endothelial dysfunction is a precocious marker of atherosclerosis (ATS). Pro-inflammatory cytokines (such as TNFα, IL-1, and IL-6) play an important role in synovial inflammation and ATS progression. Therefore, targeting inflammation is essential to controlling RA and preventing CVD. Present guidelines emphasize the importance of disease control, but studies show that RA- treatment has a different influence on CV risk. Based on the excessive risk for CV events in RA, permanent evaluation of CVD in these patients is critical. CVD risk calculators, designed for the general population, do not use RA-related predictive determinants; also, new scores that take into account RA-derived factors have restricted validity, with none of them encompassing imaging modalities or specific biomarkers involved in RA activity.

Abstract
Autophagy is considered as an important intracellular mechanism that degrades cytoplasmic components to furnish additional energy. It has cytoprotective effects through the degradation of intracellular pathogens, damaged organelles, and protein aggregates. On the other hand, there are reports of an association between autophagy and autoimmune diseases. Indeed, it has been evident that autophagy is dysregulated in various autoimmune diseases including rheumatoid arthritis (RA). Autophagy is implicated in the maturation survival and proliferation of various immune and non-immune cells, which play pivotal roles in RA pathogenesis. Additionally, autophagy seems to be involved in citrullination and presentation of citrullinated peptides to T lymphocyte cells. Presentation of citrullinated peptides through MHC compartments to the T cells leads to immune response and chronic inflammation. Evidence suggests that autophagy could be implicated in apoptosis resistance of RA fibroblast-like synoviocyte (RA FLS), osteoclastogenesis, and finally severe bone and cartilage destruction. Since autophagy could be an important phenomenon in RA pathogenesis, we summarized the roles of autophagy in citrullination, osteoclastogenesis, RA FLS cells survival, apoptosis resistance of cells, lymphocyte homeostasis and its clinical outcomes in RA disease.

Abstract
INTRODUCTION Rheumatoid arthritis (RA) is one of the most common prevalent autoimmune diseases. The 1858 C/T (rs2476601) single nucleotide polymorphism (SNP) within the PTPN22 gene has been associated with susceptibility to inflammatory based diseases in several populations. It is implicated that altered cytokine production has a potential pathogenic role in the development of RA. The aim of this work was to analyze the association of 1858 C/T PTPN22 polymorphism in RA patients with cytokine profiles. MATERIALS AND METHODS This study was performed on 120 RA patients who were referred to the Rheumatology Research Centre, Shariati Hospital (Tehran, Iran), and 120 healthy controls. Genomic DNA was extracted and genotyped for 1858 C/T PTPN22 gene SNP using the PCR-RFLP technique. Serum levels of IL-2, IL-4, IL-6, IL-10, TNF-α and IFN-γ as well as Anti-CCP and RF was measured by ELISA method. RESULTS Results showed that 1858 C/T PTPN22 SNP significantly (P = 0.007, OR = 2.321, 95% CI = 1.063-5.067) associated with RA. The 1858 T allele frequency was also significantly increased in RA patients in comparison to the controls (P = 0.008, OR = 3.583, 95% CI = 1.3-9.878). Our data demonstrated a significant reduction of IL-4 and IL-10 in PTPN22 1858C/T compared to 1858C/C RA patients. In addition, upregulation of IL-6, IFN-γ, and TNF-α was observed in PTPN22 1858C/T vs. 1858C/C RA patients. DISCUSSION Our findings implicate altered cytokine profiles as a possible pathogenic mechanism by which the 1858 T allele may contribute to the progress of RA.

Abstract
Multiple studies have shown that there is a pre-clinical period preceding the development of rheumatoid arthritis (RA). During this period, complex interactions between the environmental and genetic causes occur, and the expression "preclinical RA" has been proposed to define it. Early treatment intervention is associated with less joint damage and has an increased possibility of achieving remission. In this review, we provide an overview of the preclinical phases of RA, new immunological and imaging biomarkers, and the clinical features, and the management of individuals at-risk of developing RA.

Abstract
Rheumatoid arthritis is an autoimmune disease with a poor prognosis. Pyroptosis is a type of proinflammatory programmed cell death that is characterised by the activation of caspase-1 and secretion of the proinflammatory cytokines interleukin (IL)-1β/18. Previous reports have shown that pyroptosis is closely related to the development of some autoimmune diseases, such as rheumatoid arthritis. The decrease in the pH of joint fluid is a main pathogenic feature of RA and leads to excessive apoptosis in chondrocytes. Acid-sensitive ion channels (ASICs) are extracellular H+-activated cation channels that mainly influence Na+ and Ca2+ permeability. In this study, we investigated the role of Ca2+ in acid-sensing ion channel 1a-mediated chondrocyte pyroptosis in an adjuvant arthritis rat model. The expression of apoptosis-associated speck-like protein, NLRP3, caspase-1, ASIC 1a, IL-1β and IL-18 was upregulated in the joints of rats compared with that in normal rats, but the expression of Col2a in cartilage was decreased. However, these changes were reversed by amiloride, which is an inhibitor of ASIC1a. Extracellular acidosis significantly increased the expression of ASIC1a, IL-1β, IL-18, ASC, NLRP3 and caspase-1 and promoted the release of lactate dehydrogenase. Interestingly, Psalmotoxin-1 (Pctx-1) and BAPTA-AM inhibited these effects. These results indicate that ASIC1a mediates pyroptosis in chondrocytes from AA rats. The underlying mechanism may be associated with the ability of ASIC1a to promote [Ca2+]i and upregulate the expression of the NLRP3 inflammasome.

Abstract
OBJECTIVES Recent evidence has demonstrated that UBASH3A play a pivotal role in multiple autoimmune diseases. In this study, we explored the association between UBASH3A gene single-nucleotide polymorphisms (SNPs) and rheumatoid arthritis (RA) in a Chinese Han population. We also comparatively evaluated the UBASH3A expression profile in peripheral blood mononuclear cells (PBMCs) from patients with RA and healthy controls. METHODS Four UBASH3A polymorphisms (rs1893592, rs11203203, rs2277798, and rs3788013) were studied in 553 patients with RA and 587 controls in a Chinese population. Genotyping was performed using the Fluidigm 192.24 Dynamic Array Integrated Fluidic Circuit (IFC). For gene expression study, UBASH3A mRNA levels of 30 RA patients and 31 healthy individuals were assessed by real-time quantitative polymerase chain reaction (RT-qPCR). Data were analyzed by SPSS 19.0 software. RESULTS A significant association between rs1893592 polymorphism and RA was found under all genetic models (all p<.05). We also discovered a significant association between rs3788013 polymorphism and RA in the allele and genotype distributions, as well as the recessive model (all p<.05). Moreover, we found the genotype distribution and allele frequency of rs1893592 were significantly associated with RF phenotype in the RA patients (χ2 = 6.786, p=.034; χ2 = 4.534, p=.033; respectively). We also found the genotype distribution and allele frequency of rs2277798 were significantly associated with anti-CCP phenotype in the RA patients (χ2 = 7.873, p=.020; χ2 = 4.473, p=.034; respectively). However, we did not detect any significant associations between rs11203203 and RA susceptibility and autoantibody profiles (all p>.05). The mRNA expression of UBASH3A was increased in PBMCs of patients with RA when compared to healthy controls (p=.001). CONCLUSIONS Our observations suggested that the dysregulation of UBASH3A might be associated with the pathogenesis of RA, and UBASH3A gene polymorphisms (rs1893592 and rs3788013) might contribute to RA susceptibility in Chinese Han population.

Abstract
Alopecia universalis (AU) is a condition which causes generalized hair loss of the body. It is postulated that autoimmunity plays an important role in its pathogenesis. It is characterized by the involvement of multiple inflammatory cytokines such as tumor necrosis factor-alpha and multiple interferons. Hence, biologics like tumor necrosis factor alpha (TNF-α) antagonist may be used to block this inflammatory process. It is not very commonly appreciated that the use of biologics can lead to alopecia areata. Here, we report a case of severe alopecia areata which progressed to AU after etanercept administration. We here describe a 23-year-old unmarried female who was a known case of rheumatoid arthritis who developed AU after 6 months of continuous treatment with etanercept. TNF-α antagonist may not play a sufficient role in the treatment of alopecia areata. There exists a strong and significant connection between TNF-α blockers and development of alopecia and specifically AU and their role in the pathophysiology of the disease should be called into question if our findings are observed again.

Abstract
Background: STAT4 rs7574865 polymorphism has been evidently associated with susceptibility to Rheumatoid Arthritis (RA) in European and Eastern Asian populations, whereas studies in other countries reported otherwise. Objective: We investigated the distribution of STAT4 rs7574865 polymorphism in a group of Syrian RA patients. Methods: Eighty-one RA patients and forty healthy controls were enrolled and STAT4 rs7574865 was genotyped by direct sequencing. RA patients were stratified according to Anti-Citrullinated Protein Antibodies (ACPA) status for analysis. Results: Minor T allele frequencies were 30.4%, 16.7%, and 23.8% in ACPA-positive RA patients, ACPA-negative RA patients, and healthy controls, respectively. No significant differences in STAT4 rs7574865 allele/genotype frequencies were found between ACPA-positive RA patients, ACPA-negative RA patients, and healthy controls (P>0.05). Conclusion: STAT4 rs7574865 TT genotype showed a potential impact on ACPA positivity in Syrian RA patients. However, STAT4 rs7574865 effect on RA onset and severity is minor compared to other genetic factors such as HLA-DRB1 shared epitope alleles.

Abstract
This study investigated the impact of seven polymorphisms in genes of folate transport and (de)glutamation pathway on methotrexate polyglutamate levels and response in patients with rheumatoid arthritis. This prospective study included patients with rheumatoid arthritis. They were treated with methotrexate (up to 25 mg per week) for 24 weeks and categorized by EULAR response criteria into responders (good and moderate) and non-responders. Using real-time Taqman discrimination assay, SNPs were genotyped-rs1045642 (ABCB1 3435C>T), rs1128503 (ABCB1 1236C>T), rs10106 (FPGS 1994A>G), rs1544105 (FPGS G>A), rs11545078 (GGH 452C>T), rs3758149 (GGH -401C>T), and rs1051266 (RFC1 80G>A). RBC methotrexate polyglutamate1-5(MTX-glu1-5) levels were determined at 4, 8, 16, and 24 weeks using by reverse phase HPLC using C-18 column followed by post column photo-oxidation. This study included 117 patients with rheumatoid arthritis (M:F = 14:103). The mean dose of methotrexate at 24 weeks was 22.0 ± 4.0 mg, with data on DAS28(3) at 24 weeks available in 96 patients-61 responders and 35 non-responders. Minor allele of GGH 452C>T had an association with non-response (odds ratio 2.9, 95% CI 1.4-5.6) and assuming the dominance of C, the recessive genetic model found GGH 452C>T CC genotype (odds ratio 9.5, 95% CI 1.2 to 76.0) was significantly associated with response. However, there was no difference in MTX-glu1-5 levels among the various genotypes of this SNP (p = 0.9). Other SNPs were neither associated with response nor with alteration in methotrexate polyglutamate levels. On logistic regression, GGH 452C>T CC genotype and DAS28(3) at baseline were independent predictors of response. GGH 452C>T CC genotype was associated with response to methotrexate. None of the SNPs affected MTX-glu1-5levels.

Abstract
AIM Rheumatoid arthritis (RA) as an inflammatory autoimmune disease affects the synovial joints as well as other organs and tissues. Since aberrant expression of MIC molecules has been observed in RA patient, MIC genotypes might play certain roles in the development of RA. METHOD To explore the association of MICA and MICB polymorphisms with RA in a Han Chinese population in Hainan Island, samples from 172 RA and 137 healthy controls were genotyped for MICA and MICB. RESULTS Our results indicated that MICB*002 and MICB*014 were less frequent in RA patients than in controls (P = 0.000, 0.005) while there were higher percentages of RA patients carrying MICA*009 and MICA*A6 (P = 0.005). CONCLUSION Different MIC variants might modulate the autoimmune reaction differently in RA disease and therefore serve as protective or risk factors.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is an autoimmune inflammatory disorder of unknown etiology. IL-10 stimulates B cell survival and is involved in antibody isotype switching. The serum IL-10 levels are increased in RA patients. Ethnicity influences polymorphisms in cytokine genes. Therefore, this study was designed to explore possible association, if any, between polymorphism of IL10-1082 A/G, serum cytokine levels, inflammatory markers and gene expression in RA patients of North India. METHODOLOGY A total of 187 RA patients classified according to American college of rheumatology 2010 criteria and 214 controls were included in the study. Levels of serum IL-10 and inflammatory markers were estimated by ELISA. PCR-RFLP was used to analyze IL10-1082 A/G polymorphism. Quantitative real time PCR was used to measure the mRNA expression of IL-10 gene. RESULTS The serum inflammatory markers were significantly higher in RA patients. Circulating IL-10 levels were positively and significantly correlated with RF (r = 0.28), anti-CCP (r = 0.26), CRP (r = 0.17) and mRNA expression levels (r = 0.59) among RA patients. Homozygous mutant variant (GG) and heterozygous mutant variant (AG) were associated with patients of RA (OR = 2.87 and 1.55, p < 0.05) as compared to controls. The association still persisted when the heterozygous and homozygous mutants (AG + GG) were clubbed together (OR = 1.67, p < 0.05). The mRNA expression of IL-10 was found to be 3.63 folds higher (housekeeping gene, β-actin) and 2.42 folds higher (housekeeping gene, 18S rRNA) in RA patients as compared to controls. CONCLUSION The results indicate that IL10-1082 A/G polymorphism is associated with genetic susceptibility/predisposition to RA in North Indian population.

Abstract
Since the discovery of HLA 60 years ago, it has contributed to the understanding of the immune system as well as of the pathogenesis of several diseases. Aside from its essential role in determining donor-recipient immune compatibility in organ transplantation, HLA genotyping is meanwhile performed routinely as part of the diagnostic work-up of certain autoimmune diseases. Considering the ability of HLA to influence thymic selection as well as peripheral anergy of T cells, its role in the pathogenesis of autoimmunity is understandable. The aim of this paper is to provide a brief overview of the role and current clinical relevance of HLA-B27 in spondyloarthritis and HLA-B51 in Behçet's disease as well as HLA-DQ2/DQ8 in celiac disease and HLA-DRB1 in rheumatoid arthritis and to discuss possible future implications.

Abstract
Background We examined the United States National Health and Nutrition Examination Survey (NHANES) database to determine factors associated with rheumatoid arthritis (RA) in adults 20 to 55 years of age. Methods NHANES data collected between 2007 and 2014, excluding the 2011-2012 period, were used. Subjects were divided into those with and without RA. Demographic, clinical, and lifestyle factors were compared between the groups. Results After applying inclusion/exclusion criteria, 8,789 persons were included in the study (8,483 without RA, 306 with RA). Multivariable analysis indicated that advanced age (odds ratio [OR] = 1.09, 95% CI [1.07-1.11], P < 0.001), regular smoking (OR = 2.19, 95% CI [1.49-3.21], P < 0.001), diabetes (OR = 2.00, 95% CI [1.35-2.95], P = 0.001), obesity (reference, normal or underweight; OR = 3.31, 95% CI [2.05-5.36], P < 0.001), and osteoporosis (OR = 3.68, 95% CI [1.64-8.22], P = 0.002) were positively associated with RA. Covered by health insurance (OR = 1.81, 95% CI [1.12-2.93], P = 0.016) and living in poverty (OR = 2.96, 95% CI [1.88-4.65], P < 0.001) were also associated with having RA. Mexican American, Hispanic white or other Hispanic ethnicity (reference, non-Hispanic white; OR = 0.54, 95% CI [0.31-0.96], P = 0.036), appropriate sleep duration (about 6-11 h, OR = 0.46, 95% CI [0.32-0.65], P < 0.001), and insufficient vitamin A intake (reference, recommended; OR = 0.70, 95% CI [0.50-0.98], P = 0.036) were negatively associated with RA. Discussion Some factors associated with RA are potentially modifiable.

Abstract
Rheumatoid arthritis (RA) is an inflammatory circumstance, which has been associated with increased risk of cardiovascular disease (CVD). Although RA management has been promoted, mortality rate due to CVD remains remarkable. Approximately, 50% of premature death cases in RA are attributable to CVD. RA patients develop atherosclerosis in a greater amount than the general population. Moreover, atherosclerotic lesions develop rapidly in RA patients and might be more susceptible to rupture. The inflammatory condition of RA, such as cytokines, abnormally activated immune cells, play a role in the initiation, perpetuation and exacerbation of atherosclerosis. RA and CVD have genetic and environmental contributing risk factors in common, implying to potential coincidence of both disorders. Accelerated atherosclerosis in RA is attributed to inflammation, which carries its role out both through modulation of traditional risk factors and direct effect on the vessel wall. Hence, anti-inflammatory medications in RA like tumor necrosis factor blockers might have a beneficial effect on preventing cardiovascular development. Increasing age, smoking, hypertension, male gender, hypercholesterolemia and diabetes are enumerated as traditional CVD risk factors. Hopefully, further understanding of the cardiovascular risk factors by perceiving the disease conditions behind CVD, will improve management of cardiovascular risks in patients with RA.

Rheumatoid Arthritis: The Stride from Research to Clinical Practice. Int J Mol Sci 2016; 17:ijms17060900.

Abstract
Over 70 different genetic variants with a significant association with rheumatoid arthritis (RA) have been discovered. Anti-citrullination protein antibodies (ACPA)-positive RA variants are more well-defined than their ACPA-negative counterparts. The human leukocyte antigen, HLA-DRB1 locus remains the prime suspect in anti-citrullination protein antibodies (ACPA)—positive RA. Different HLA-DRB1 alleles are linked to RA susceptibility across different ethnicities. With evolving techniques, like genome-wide association studies (GWAS) and single nucleotide polymorphism (SNP) arrays, more non-HLA susceptibility loci have been identified for both types of RA. However, the functional significance of only a handful of these variants is known. Their roles include increasing susceptibility to RA or in determining the speed at which the disease progresses. Additionally, a couple of variations are associated with protection from RA. Defining such clear-cut biological functions can aid in the clinical diagnosis and treatment of RA. Recent research has focused on the implication of microRNAs, with miR-146a widely studied. In addition to disease susceptibility, genetic variations that influence the efficacy and toxicity of anti-RA agents have also been identified. Polymorphisms in the MTHFR gene influence the effectiveness of methotrexate, the first line of therapy in RA. Larger studies are, however, needed to identify potential biomarkers for early disease identification and monitoring disease progression.

Abstract
PURPOSE OF REVIEW Rheumatoid arthritis (RA) is a heterogeneous chronic immune-mediated inflammatory disease, associated with significant morbidity and reduced life expectancy. Here, we review recent discoveries; particularly those which have attempted to integrate genome-wide association studies (GWAS) with biological pathways and cell types known to play a role in disease pathology in order to expand our current understanding of the pathogenesis of RA. As the role of stromal cells in the pathogenesis of RA has been reviewed in detail in Current Opinions in Rheumatology, this area will not be covered in this review. RECENT FINDINGS Although our understandings of the pathogenic processes that drive disease in RA remain incomplete, remarkable advances over the past year can be highlighted. GWAS have raised awareness of important new risk loci with genes that either are the targets of approved therapies for RA, or involve pathways for drugs that could be repurposed from other disease indications such as cancer. Furthermore, promising strides have been made in predicting the likelihood of developing RA in those at risk using human leukocyte antigen (HLA), smoking, and autoantibody status prediction models. These findings give a fresh insight into RA pathogenesis and help identify new, or repurpose known therapeutic targets from other disease areas. SUMMARY The findings discussed in this review underscore the progress made to date and the need for future studies, investigating disease mechanisms in RA, with particular interest in at-risk RA gene loci, their function in immune and stromal cells within the synovium, and how they interact with environmental factors to initiate and perpetuate disease.

Abstract
Autophagy appears to play a dual role in eukaryotic cells. It manifests cytoprotective effects through the regulation of catabolic processes and the clearance of pathogens; however, a correlation between autophagy and the pathogenesis of autoimmune/autoinflammatory conditions has recently been described. Autophagy has emerged as a mediator in the pathogenesis of RA. Autophagy may regulate apoptosis resistance and hyperplasia in synovial fibroblasts, promote osteoclastogenesis and stimulate osteoclast-mediated bone resorption through the delivery of citrullinated peptides to MHC compartments, which results in the activation of the innate and adaptive immune response, thereby resulting in RA. Given the likely importance of autophagy in the pathogenesis of RA, here we reviewed the detailed mechanisms concerning the pathogenicity of autophagy and autophagy proteins in RA.

Abstract
Systemic lupus erythematosus (SLE) is a prototypic autoimmune disease that is caused by genetic and environmental factors. Current evidence shows that the CD40-CD40L system plays a crucial role in the development, progression and outcome of SLE. CD40, which stimulates lymphocyte proliferation and differentiation, is an important immunomodulator and is expressed in the thyroid follicular cells as well as antigen-presenting cells. The aim of the present study was to investigate whether CD40 gene polymorphism confers susceptibility to SLE and its impact on CD40 expression in Chinese. We analyzed four single nucleotide polymorphisms of CD40 gene rs1883832C/T, rs13040307C/T, rs752118C/T, and rs3765459G/A in 205 patients with SLE and 220 age- and sex-matched controls, using Snapshot SNP genotyping assays and DNA sequencing method. Soluble CD40 (sCD40) levels were measured by ELISA. There were significant differences in the genotype and allele frequencies of CD40 gene rs1883832 C/T polymorphism between the group of patients with SLE and the control group (P < 0.05). sCD40 levels were increased in patients with SLE compared with controls (P < 0.01). Moreover, genotypes carrying the CD40 rs1883832 T variant allele were associated with increased CD40 levels compared with the homozygous wild-type genotype in patients with SLE. The rs1883832 C/T polymorphism of CD40 and its sCD40 levels were associated with SLE in the Chinese population. These data suggest that CD40 gene may play an essential role in the development of SLE.

Abstract
OBJECTIVE E26 transformation specific sequence 1 (ETS-1) belongs to the ETS family of transcription factors that regulate the expression of various immune-related genes. Increasing evidence indicates that ETS-1 could contribute to the pathogenesis of autoimmune disease. Recent research has provided evidence that ETS-1 might correlate with rheumatoid arthritis (RA), but it's not clearly defined. In this study, we aimed to identify whether polymorphisms of ETS-1 play a role in Rheumatoid arthritis (RA) susceptibility and development in Chinese Han population. METHODS Four single nucleotide polymorphisms (SNPs) within ETS-1 were selected based on HapMap data and previous associated studies. Whole blood and serum samples were obtained from 158 patients with RA and 192 healthy subjects. Genotyping was performed with polymerase chain reaction-high resolution melting (PCR-HRM) assay and the data was analyzed using SPSS17.0. RESULTS A significantly positive correlation was observed between the SNP rs73013527 of ETS-1 and RA susceptibility, DAS28 and CRP (P<0.001, P = 0.001, and P = 0.028, respectively). Carriers of the haplotype CCT or TCT for rs4937333, rs11221332 and rs73013527 were associated with decreased risk of RA as compared to controls. No statistical significant difference was observed in the distribution of rs10893872, rs4937333 and rs11221332 genotypes between RA patients and controls. CONCLUSIONS Our data further supports that ETS-1 has a relevant role in the pathogenesis and development of RA. Allele T of rs73013527 plays a protective role in occurrence of RA but a risk factor in the high disease activity. Rs10893872, rs11221332 and rs4937333 are not associated with RA susceptibility and clinical features.

Abstract
Nanotechnology provides new opportunities in human medicine, mainly for diagnostic and therapeutic purposes. The autoimmune disease rheumatoid arthritis (RA) is often diagnosed after irreversible joint structural damage has occurred. There is an urgent need for a very early diagnosis of RA, which can be achieved by more sensitive imaging methods. Superparamagnetic iron oxide nanoparticles (SPION) are already used in medicine and therefore represent a promising tool for early diagnosis of RA. The focus of our work was to investigate any potentially negative effects resulting from the interactions of newly developed amino-functionalized amino-polyvinyl alcohol coated (a-PVA) SPION (a-PVA-SPION), that are used for imaging, with human immune cells. We analyzed the influence of a-PVA-SPION with regard to cell survival and cell activation in human whole blood in general, and in human monocytes and macrophages representative of professional phagocytes, using flow cytometry, multiplex suspension array, and transmission electron microscopy. We found no effect of a-PVA-SPION on the viability of human immune cells, but cytokine secretion was affected. We further demonstrated that the percentage of viable macrophages increased on exposure to a-PVA-SPION. This effect was even stronger when a-PVA-SPION were added very early in the differentiation process. Additionally, transmission electron microscopy analysis revealed that both monocytes and macrophages are able to endocytose a-PVA-SPION. Our findings demonstrate an interaction between human immune cells and a-PVA-SPION which needs to be taken into account when considering the use of a-PVA-SPION in human medicine.

Abstract
Background Currently, natural products have built a well-recognized role in the management of many degenerative diseases, mainly rheumatoid arthritis. Recent studies suggest that Spirulina, a unicellular blue-green alga, may have a variety of health benefits and curative properties and is also competent of acting as an anti-inflammatory, antioxidant and recently anti-angiogenic agent. In the present study, the antioxidant and the immunomodulatory effect of Spirulina platensis as well as its anti-angiogenic effect against complete Freund's adjuvant-induced arthritis (AIA) in rat model were tested. Results We found that the development of arthritis was concealed; moreover it successfully inhibited the development of macroscopic as well as microscopic and histopathological lesions in AIA rats when compared to control. Spirulina treated group showed a higher survival rate and moreover, it reduced the clinical score of RA in a dose dependent manner. Furthermore, Spirulina decreased serum levels of COX-2, TNF-α, IL-6, TBARS, VEGF and increased serum levels of GSH compared to the RA non-treated group. Conclusions The present study concluded that Spirulina is able to restrain the changes produced through adjuvant-induced arthritis. The suppressing effect of Spirulina could be attributed, at least in part, to anti-inflammatory, antioxidant and anti-angiogenic properties.

Abstract
Rheumatoid arthritis (RA) has long been associated with increased cardiovascular risk, but despite substantial improvements in disease management, mortality remains high. Atherosclerosis is more prevalent in RA than in the general population, and atherosclerotic lesions progress at a faster rate and might be more prone to rupture, causing clinical events. Cells and cytokines implicated in RA pathogenesis are also involved in the development and progression of atherosclerosis, which is generally recognized as an inflammatory condition. The two diseases also share genetic and environmental risk factors, which suggests that patients who develop RA might also be predisposed to developing cardiovascular disease. In RA, inflammation and atherosclerosis are closely linked. Inflammation mediates its effects on atherosclerosis both through modulation of traditional risk factors and by directly affecting the vessel wall. Treatments such as TNF inhibitors might have a beneficial effect on cardiovascular risk. However, whether this benefit is attributable to effective control of inflammation or whether targeting specific cytokines, implicated in atherosclerosis, provides additional risk reduction is unclear. Further knowledge of the predictors of cardiovascular risk, the effects of early control of inflammation and of drug-specific effects are likely to improve the recognition and management of cardiovascular risk in patients with RA.

Abstract
BACKGROUND Tumour necrosis factor (TNF)-alpha inhibitors are beneficial for the treatment of rheumatoid arthritis (RA) in terms of reducing the risk of joint damage, improving physical function and improving quality of life. This Cochrane review is an update of a review of the treatment of RA with certolizumab pegol that was first published in 2011. OBJECTIVES To assess the clinical benefits and harms of certolizumab pegol (CDP870) in patients with RA who have not responded well to conventional disease-modifying anti-rheumatic drugs (DMARDs). SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (The Cochrane Library 2014, Issue 5), MEDLINE, EMBASE, Scopus, TOXLINE, Web of Knowledge; websites of the US Food and Drug Administration (FDA) and European Medicines Evaluation Agency (EMEA); reference lists of articles; and searched http/clinicaltrials.gov. The searches were updated from 2009 (date of last search for the original review) to 5 June 2014. SELECTION CRITERIA Randomised controlled trials that compared certolizumab pegol with any other agent including placebo or methotrexate (MTX) in adult patients with active RA despite current or prior treatment with conventional disease-modifying anti-rheumatic drugs (DMARDs), such as MTX. DATA COLLECTION AND ANALYSIS Two authors independently assessed search results, trial quality and extracted data. Disagreements were resolved by discussion or referral to a third author. MAIN RESULTS Eleven trials were included in this update. Ten (4324 patients) were included in the pooled analysis for benefits, five more than previously, and 10 (3711 patients) in the pooled analysis for harms, four more trials (1930 patients) than previously. The duration of follow-up varied from 12 to 52 weeks and the range of doses of certolizumab pegol varied from 50 to 400 mg given subcutaneously (sc). In phase III trials, the control was placebo plus MTX in five trials and placebo in four trials. The risk of bias of the included studies was assessed as low but there may have been a risk of attrition bias.Statistically significant improvements were observed at 24 weeks with the approved dose of 200 mg certolizumab pegol every other week, in 1) American College of Rheumatology (ACR) 50% improvement: 27% absolute improvement (95% CI 20% to 33%), NNT of 4 (95% CI 3 to 8), risk ratio (RR) 3.80 (95% CI 2.42 to 5.95); 2) the Health Assessment Questionnaire (HAQ): -12% absolute improvement (95% CI -9% to -14%), NNT of 6 (95% CI 5 to 8), mean difference (MD) - 0.35 (95% CI -0.43 to -0.26) (scale 0 to 3); 3) Disease Activity Score (DAS) remission improvement: absolute improvement 11% (95% CI 8% to 15%), NNT of 9 (95% CI 4 to 20), RR 8.47 (95% CI 4.15-17.28); and 4) radiological changes: erosion score (ES) absolute improvement -0.29% (95% CI -0.42% to -0.17%), NNT of 6 (95% CI 4 to 10), MD -0.67 (95% CI -0.96 to -0.38) (scale 0 to 230). Serious adverse events were statistically significantly more frequent for certolizumab pegol (200 mg every other week) with an absolute rate difference of 4% (95% CI 2% to 6%), NNTH of 32 (95% CI 17 to 88), Peto odds ratio (OR) 1.77 (95% CI 1.27 to 2.46). There was a statistically significant increase in all withdrawals in the placebo groups (for all doses and all follow-ups) with an absolute rate difference of -34% (95% CI -18% to -50%), NNTH of 4 (95% CI 3 to 5), NNTH of 4 (95% CI 3 to 5), RR 0.42 (95% CI 0.36 to 0.50); and there was a statistically significant increase in all withdrawals due to adverse events in the certolizumab groups (for all doses and all follow-up) with an absolute rate difference of 2% (95% CI 1% to 3%), NNTH of 55 (95% CI 27 to 238), Peto OR 1.66 (95% CI 1.15 to 2.37).The risk of bias was low and the quality of evidence was downgraded to moderate because of high rates of dropouts (> 20%) in most of the trials. We did not find any problems with inconsistency, indirectness, imprecision or publication bias. AUTHORS' CONCLUSIONS The results and conclusions did not change from the previous review. There is moderate-level evidence from randomised controlled trials that certolizumab pegol alone or combined with methotrexate is beneficial in the treatment of RA. Adverse events were more frequent with active treatment. We found a potential risk of serious adverse events.

Abstract
BACKGROUND It has been reported that two single nucleotide polymorphisms (SNPs) rs2910164 in miRNA-146a and rs3746444 in miRNA-499 might be associated with the susceptibility to rheumatoid arthritis (RA). Owing to mixed and inconclusive results, we conducted a meta-analysis to systematically summarize and clarify the association between the two SNPs and RA risk. METHODOLOGY/MAIN RESULTS A systematic search of studies on the association of two SNPs with susceptibility to RA was conducted in PubMed and Embase. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were used to pool the effect size. A total of 6 case-control studies on rs2910164 and 3 studies on rs3746444 were included. Though no evidence of association was found between rs2910164 polymorphism and RA risk in all the genetic models, a trend of reduced risk could be drawn. (C versus G: OR=0.93, 95% CI 0.82-1.05; GC versus GG: OR=0.89, 95% CI 0.73-1.10; CC versus GG: OR=0.84, 95% CI 0.64-1.10; GC/CC versus GG: OR=0.89, 95% CI 0.73-1.08; CC versus GC/GG OR=0.94, 95% CI 0.77-1.14). A significant increased risk of RA was observed in the rs3746444 polymorphism in homozygote comparison, recessive comparison, and allele comparison, but there was insufficient data to fully confirm the association of RA and rs3746444 in miRNA-499. CONCLUSIONS MiRNA-146a rs2910164 polymorphism is not associated with RA risk, while miRNA-499 rs3746444 polymorphism is correlated with RA risk. However, the results of miRNA-499 rs3746444 should be interpreted with caution due to limited sample and heterogeneity. Large-scale and well-designed studies are needed to validate our findings.

AIM The aim of our study was to determine the genetic associations between polymorphisms of the TNFα gene (-308G/A and -238G/A) with disease susceptibility and severity in patients with rheumatoid arthritis (RA) in an ethnic Kashmiri population. METHODS Allele and genotype frequencies of TNFα-308G/A and TNFα-238G/A polymorphisms were compared between 150 RA patients and 200 healthy controls by using polymerase chain reaction - restriction fragment length polymorphism method. Demographic, clinical and serological data were prospectively evaluated. Disease activity score (DAS28) was also assessed. RESULTS We did not find any significant association between TNFα-308G/A and TNFα-238G/A polymorphism and RA risk (P > 0.05), but TNFα-308GG genotype was associated significantly with rheumatoid factor seropositivity (P < 0.01) and TNFα-238GA genotype was associated with swollen joint count < 5 (P = 0.04) as well as with less severe disease activity as measured by DAS28 score (P = 0.02). CONCLUSION Our findings suggest the possible roles of TNFα-308GG and TNFα-238GA as important determinants for the development of certain manifestations and disease severity in RA in ethnic Kashmiri population.

Abstract
Rheumatoid arthritis (RA) is a complex and common systemic autoimmune disease characterized by synovial inflammation and hyperplasia. Multiple proteins, cells, and pathways have been identified to contribute to the pathogenesis of RA. Galectins are a group of lectins that bind to β-galactoside carbohydrates on the cell surface and in the extracellular matrix. They are expressed in a wide variety of tissues and organs with the highest expression in the immune system. Galectins are potent immune regulators and modulate a range of pathological processes, such as inflammation, autoimmunity, and cancer. Accumulated evidence shows that several family members of galectins play positive or negative roles in the disease development of RA, through their effects on T and B lymphocytes, myeloid lineage cells, and fibroblast-like synoviocytes. In this review, we will summarize the function of different galectins in immune modulation and their distinct roles in RA pathogenesis.

Abstract
Objective. To determine the prevalence and impact of autoimmune thyroid disease (AITD) in patients with rheumatoid arthritis (RA). Methods. Eight-hundred patients were included. The association between AITD and RA was analyzed was analyzed by bivariate and multivariate analysis. In addition, a literature review was done focusing on geographical variations. Results. In our cohort the prevalence of AITD was 9.8% while the presence of antibodies was 37.8% for antithyroperoxidase enzyme (TPOAb) and 20.8% for antithyroglobulin protein (TgAb). The presence of type 2 diabetes, thrombosis, abnormal body mass index, and a high educational level was positively associated with AITD. The literature review disclosed a geographical variation of AITD in RA ranging from 0.5% to 27%. Autoantibody prevalence ranges from 6% to 31% for TgAb, 5% to 37% for TPOAb, and from 11.4% to 32% for the presence of either of the two. Conclusion. AITD is not uncommon in RA and should be systematically assessed since it is a risk factor for developing diabetes and cardiovascular disease. These results may help to further study the common mechanisms of autoimmune diseases, to improve patients' outcome, and to define public health policies. An international consensus to accurately diagnose AITD is warranted.

Abstract
OBJECTIVE ETS1 belongs to the ETS family of transcription factors that regulate the expression of various immune-related genes. The aim of this study was to identify whether the ETS1 single nucleotide polymorphism (SNP) rs11221332, described in Caucasian subjects, plays a role in rheumatoid arthritis (RA) susceptibility. METHODS We genotyped this polymorphism in 136 unrelated patients with RA and 147 healthy individuals with no history of autoimmune disease. Genotyping was performed with a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay and the data were analysed using SPSS statistical software. RESULTS A statistically significant difference was observed in the distribution of the rs11221332 genotypes between RA patients and controls (p = 0.041). Comparing the distribution of rs11221332 alleles between the groups studied, a greater difference was found [odds ratio (OR) 1.504, 95% confidence interval (CI) 1.036-2.183; p = 0.039]. CONCLUSIONS The present study revealed, for first time, the positive association of a polymorphism in the sequence of the ETS1 transcription factor with RA susceptibility. Further studies in other ethnic groups of patients are needed to confirm the results of the present genetic association study related to ETS1, a widely used transcription factor in the regulation of the expression of various genes.

Abstract
INTRODUCTION Rheumatoid arthritis (RA) is a common autoimmune disease with a complex genetic background. The PTPN22 gene encodes lymphoid tyrosine phosphatase LYP, a potent negative regulator of T cell activation. Polymorphic variants of this gene have previously been associated with various autoimmune disorders. The +1858C/T single-nucleotide polymorphism (SNP) (rs2476601), in the exon 14 of the PTPN22 gene has been associated with susceptibility to RA in several population. OBJECTIVE The aim of this work was to investigate whether the +1858C/T of the PTPN22 gene is associated with susceptibility to RA in Western Mexico population. METHODS A total of 309 unrelated RA patients, classified according to American College of Rheumatology (ACR) 1987 criteria, as well as 347 controls residents from Western Mexico were recruited for this study. The DNA samples were genotyped for +1858C/T PTPN22 gene SNP using the PCR-RFLP technique. Antibodies to cyclic citrullinated peptides (anti-CCP) were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS The frequency of +1858T risk allele was significantly increased in patients with RA compared with controls (p=0.001, OR=2.83, 95%CI=1.50-5.32). To confirm this results we established a comparison between subjects carrying of CT+TT genotypes versus those carrying CC genotype, between both groups (p=0.004, OR=2.65, 95%CI=1.33-5.36). Nevertheless, we not observed association of the +1858C/T PTPN22 gene SNP with clinical activity and functional disability in RA patients. Likewise, the +1858T variant in RA patients seropositive for anti-CCP antibodies, increased the risk for RA (p=0.008, OR=2.5, 95%CI=1.3-5.0) when we compared with controls; however, in the group of seronegative patients, no was found significant difference (p=0.1, OR=2.5, 95%CI=0.9-7.2). CONCLUSIONS Our results support the association of the +1858T risk allele of the +1858C/T PTPN22 polymorphism with susceptibility to RA and confirm that, in combination with anti-CCP antibodies, this SNP influence the autoimmune processes towards a development of RA in Mexican population.

Abstract
OBJECTIVE Although rheumatoid arthritis (RA) has long been associated with an HLA-DRB1 shared epitope, a systematic search for other epitopes has never been conducted. In addition, the relationship between these epitopes and the binding of citrullinated autoantigens has not been investigated. We developed a program that can analyze HLA data for all possible epitopes of up to 5 amino acids and used this program to assess the shared epitope hypothesis in RA. METHODS We analyzed high-resolution data from the International Histocompatibility Working Group, which included a group of 488 patients with RA and a group of 448 racially and ethnically balanced control subjects, for all combinations of up to 5 amino acids among polymorphic HLA-DRB1 positions 8-93. Statistical significance was determined by chi-square and Fisher's exact tests, with a false discovery rate correction. RESULTS Three residues (V(11), H(13), and L(67)) were found to have the highest degree of association with RA susceptibility (P < 10(-11)), and D(70) was found to correlate best with RA resistance (P = 2 × 10(-11)). Of >2 million epitopes examined, LA(67, 74) exhibited the highest correlation with RA susceptibility (P = 2 × 10(-20); odds ratio 4.07 [95% confidence interval 3.07-5.39]). HLA alleles containing the LA(67, 74) epitope exhibited significantly greater binding to citrullinated vimentin(65-77) than did alleles containing D(70). Only 1 allele (DRB1*16:02) contained both LA(67, 74) and D(70); it bound citrullinated vimentin weakly and was not associated with RA. CONCLUSION The findings of these studies confirm the importance of HLA-DRB1 amino acids in pocket 4 for the binding of citrullinated autoantigens and susceptibility to RA.
