Abstract
The development of liver dysfunction in patients having various systemic diseases is common and has a broad differential diagnosis, at times being the initial manifestation of the disorder. Liver injury associated with systemic lupus erythematosus is heterogeneous and may present with nonspecific histology. Differentiating autoimmune hepatitis from lupus hepatitis is challenging on histologic grounds alone. Other systemic diseases that may present mostly with nonspecific findings are rheumatoid arthritis and celiac disease. More recently COVID-19 cholangiopathy and secondary sclerosing cholangitis have become increasingly recognized as distinct liver conditions. Many patients may also have intrinsic liver disease or may develop drug-induced liver injury from the treatment of the systemic disease. Timely identification of the cause of the liver dysfunction is essential and liver biopsy may help the clinician in diagnosis and management.

Bagheri-Hosseinabadi Z, Mirzaei MR, Esmaeili O, Asadi F, Ahmadinia H, Shamsoddini B, Abbasifard M. Implications of Peptidyl Arginine Deiminase 4 gene transcription and polymorphisms in susceptibility to rheumatoid arthritis in an Iranian population. BMC Med Genomics 2023; 16:104. [PMID: 37193992 DOI: 10.1186/s12920-023-01532-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2022] [Accepted: 05/03/2023] [Indexed: 05/18/2023] Open
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
Methotrexate (MTX) is used as an effective chemotherapeutic agent against autoimmune diseases and tumors. Oxidative stress and inflammation are involved in the pathogenesis of MTX-induced damage. This study aimed at examining the ameliorating effects of apigenin (API) as a natural antioxidant on MTX-induced hepatotoxicity. The rats were classified into four groups: group I: normal saline-treated, group II: MTX-treated (20 mg/kg, ip, single dose at day 7), group III: MTX + API-treated (20 mg/kg, po), and group IV: API-treated. API was administrated for 9 days. Alanine aminotransferase (ALT), alkaline phosphatase (ALP), and aspartate aminotransferase (AST) were used as biochemical factors of MTX-induced hepatic injury. In hepatic tissues, the levels of malondialdehyde (MDA), nitric oxide (NO), glutathione (GSH), and activities of antioxidant enzymes such as catalase (CAT), glutathione peroxidase (GPx), and superoxide dismutase (SOD) as oxidative stress markers along with inflammatory factors such as tumor necrosis factor-alpha (TNF-α) and interleukin 1 beta (IL-1β) were assessed. Our results showed that MTX administration significantly increased ALP, ASP, ALT, MDA, NO, TNF-α, and IL-1β levels and significantly decreased antioxidant factors such as GSH, CAT, GPx, and SOD. The API pretreatment group showed a significant rise in hepatic antioxidant markers, besides significant reductions in the serum levels of AST, ALT, and ALP and hepatic content of MDA, TNF-α, NO, and IL-1β. In addition, the hepatoprotective effect of API was confirmed by histological evaluation of the liver. API can prevent MTX-induced hepatotoxicity through mitigation of oxidative stress and inflammation.

Abstract
Objectives This study aims to improve knowledge on cardiovascular disease (CVD) risk among rheumatoid arthritis (RA) patients using a multi- language leaflet tailored to our multi-ethnic patient population. Patients and methods This was a prospective study conducted in Hospital Pulau Pinang, Malaysia, between March 2015 and June 2015. Educational intervention was provided to 96 patients (11 males, 85 females; mean age 52.4±12.9 years; range, 20 to 83 years) who fulfilled the inclusion/exclusion criteria. Questionnaires to assess knowledge of CVD risk were given to patients to be answered before reading the informative leaflet, after one hour of intervention, and during their next follow-up three months from the intervention. Both the informative leaflet and questionnaires were prepared in English and then translated into Malay and Chinese languages to suit the need of local patients. Results Our results showed that RA patients had good knowledge at baseline regarding risk of smoking, hypertension, and hyperlipidemia on increasing CVD risk and that exercise would not damage their joints. However, they had low knowledge at baseline regarding the amount of exercise needed for lower CVD risks and risk of CVD with use of anti-inflammatory drugs in RA. Total knowledge score increased significantly from baseline immediately after educational intervention. However, total knowledge score decreased after three months compared to immediate post- intervention phase while it was still significantly higher compared to baseline. The improvement was most obvious for knowledge regarding anti- inflammatory drugs and CVD risk and knowledge regarding the number of flares and CVD risk. Our study did not find any significant association between demographic characteristics and traditional cardiovascular risk factors with knowledge of CVD risk. Conclusion Rheumatoid arthritis patients have low knowledge regarding their CVD risk related to their disease. The intervention of providing an informative leaflet effectively improved the knowledge of this group of patients on CVD risk particularly in the field related to RA-specific risk.

Abstract
Introduction Methotrexate is a cytotoxic agent used in leukemia, and several other cancer types and at lower doses in auto-inflammatory diseases such as rheumatoid arthritis, ankylosing spondylitis and psoriasis. Macrolide antibiotics are effective against gram-positive and Gram-negative bacteria. They have anti-inflammatory activities as well. Clarithromycin is a macrolide with anti-inflammatory activity through blockage of the p38 MAPK signal cascade, which is involved in methotrexate-induced pulmonary toxicity. Aim In this study, the efficacy of clarithromycin in protecting against pulmonary fibrosis was investigated in the rat model for methotrexate-induced pulmonary fibrosis. Material and methods A total of 30 female rats were divided into three groups. Group I was administered intraperitoneal and intragastric saline; group II was administered oral 3 mg/kg methotrexate; and group III was administered oral 3 mg/kg methotrexate + intraperitoneal 200 mg/kg clarithromycin for 28 days. Histopathological analyses of the lung tissues were performed under light microscopy. Results Normal histopathological changes were observed in the control group. Pulmonary fibrosis was significantly higher in the methotrexate group than in the other groups (p < 0.005). Conclusions Clarithromycin was shown to be effective in protecting against methotrexate-induced pulmonary fibrosis; further studies should be performed to determine the dosage and safety.

Abstract
Although the precise etiology of Rheumatoid arthritis (RA) remains obscure, heightened immune response is thought to play a vital role in provoking joint inflammation and bone erosion. This study aims at comparatively evaluating the effects of two monoclonal antibodies Ranibizumab (RANI) as anti-VEGF antibody and Tocilizumab (TCZ) as interleukin-6 receptor (IL-6R) antagonist, against adjuvant induced arthritis in rats. CFA-induced arthritic rats were treated for three consecutive weeks with Methotrexate (MTX), TCZ and RANI monotherapy. Clinical assessment of RA, bone erosion, inflammatory, angiogenic and apoptotic markers were determined to assess the anti-arthritic effect. Liver enzymes and histopathological examination of liver and spleen were assessed to evaluate the toxicity profile of the tested therapeutic agents. MTX, TCZ and RANI monotherapy significantly enhanced the anti-arthritic parameters in comparison with the Complete Freund's Adjuvant (CFA)-induced arthritic rats through significant reduction of ankle and paw swelling. Also, they significantly reduced inflammatory, angiogenic and apoptotic markers. Importantly, Ranibizumab showed better effect than the standard anti-rheumatic drugs Methotrexate (MTX) or Tocilizumab (TCZ) in bone protection and cartilage health; hence proves to be a promising new therapeutic agent for RA.

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
PURPOSE OF THE STUDY Increasing numbers of studies show that interleukin (IL)-10 plays a key role in the pathogenesis of autoimmune diseases including rheumatoid arthritis (RA) and acts as an immunomodulatory cytokine. The purpose of the present study was to analyse the relationship between gene single nucleotide polymorphisms (SNPs) in the IL-10 gene and RA susceptibility. STUDY DESIGN We genotyped three SNPs (rs1800890, rs3024495, rs3024505) of the IL-10 gene in a Chinese population of 354 RA patients and 367 controls. Genotyping was conducted using TaqMan SNP genotyping assays. Plasma IL-10 levels were measured by ELISA. RESULTS The A allele of the rs1800890 variant was significantly related to decreased risk for RA compared with the T allele (A vs T: OR 0.580, 95% CI 0.345 to 0.975, P=0.038). No significant association between the genotype distribution of these SNPs and RA susceptibility was detected. The genotype effect of the dominant model was also evaluated, but no statistical difference was found. Further analysis in RA patients demonstrated that none of these SNPs were associated with rheumatoid factor (RF) or anti-citrullinated protein antibody (anti-CCP). In addition, no significant differences in plasma IL-10 levels were observed among RA patients with different genotypes. CONCLUSIONS The IL-10 rs1800890 variant might contribute to RA susceptibility in the Chinese population. Replication studies in different ethnic groups are required to further examine the critical role of IL-10 gene variation in the pathogenesis of RA.

Abstract
BACKGROUND Liver is the largest internal organ concerning with metabolism, hormonal balance and clarifying of the toxins. One of the main complications of methotrexate (MTX) therapy was the hepatic injury. OBJECTIVE This study was conducted to elucidate the possible protective effects of phloridzin (PHL) against MTX-induced hepatotoxicity as compared to standard agent N-acetylcysteine (NAC). MATERIALS AND METHODS Rats were randomly divided into a normal control group, a respective group (PHL 40mg/kg/day orally (p.o.) for 10 consecutive days), a hepatotoxicity control group (MTX 20mg/kg, i.p., once), and three treated groups received NAC (150mg/kg/day; a reference standard), PHL (40mg/kg/day) and PHL (80mg/kg/day) p.o. for 10 consecutive days, at the end of the day 3 of the experiment rats were administered MTX. Assessed biomarkers included serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) as liver function parameters, serum tumor necrosis factor-α (TNF-α) and cyclooxygenase-II (COX-II), as inflammatory biomarkers, hepatic total antioxidant capacity (TAC), thiobarbituric acid reactive substances (TBARS), glutathione reduced (GSH), nitrite (NO2-), catalase (CAT), glutathione-S-transferase (GST) and superoxide dismutase (SOD) as oxidative stress biomarkers. Furthermore, hepatic caspase-3 expression was assessed. Biochemical and molecular estimations reinforced by histopathological findings. RESULTS Rats pre-treated with PHL significantly reduced hepatic injury, evidenced by significant reductions in ALT, AST and LDH, TNF-α and COX-II levels, significant reductions in hepatic NO2- and TBARS levels, and significant elevations in hepatic TAC, GSH, GST, CAT and SOD levels. Additionally, downregulation of hepatic caspase-3 expression. Finally, histopathological results consistent with our previous findings. CONCLUSION PHL protects against hepatic injury in rats mainly through mitigation of oxidative stress, inflammation and apoptosis in hepatic tissues and may be promising to alleviate and early treatment of MTX-induced hepatoxicity in man.

Abstract
Many studies have evaluated the correlation between peptidylarginine deiminase 4 (PADI4) -92C/G polymorphism and rheumatoid arthritis (RA), but the results remain inconclusive. Therefore, we performed a meta-analysis in the Chinese population to provide comprehensive data on the association between PADI4 -92C/G polymorphism and RA. Eligible studies published before May 2016 were identified in PubMed and Chinese databases. The strengths of these associations were assessed by pooled odds ratios (OR) and 95% confidence interval (CI). Eight studies documenting a total of 1351 RA cases and 1585 controls were included in this meta-analysis. In the overall analysis, a significant association between the PADI4 -92C/G polymorphism and RA was found in the Chinese population (G vs C: OR=1.32, 95%CI=1.02-1.71; GG+CG vs CC: OR=1.75, 95%CI=1.20-2.53). The subgroup analyses stratified by geographic area(s) and source of controls revealed significant results in South China, in hospital-based studies and population-based studies. In summary, this meta-analysis suggested that PADI4 -92C/G polymorphism may be associated with the RA incidence in the Chinese population, especially for South China. Further studies conducted on other ethnic groups are required for definite conclusions.

Abstract
U.S. military personnel assigned to areas deemed to be at high risk for anthrax attack receive Anthrax Vaccine Adsorbed (AVA). Few cases of rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) have been reported in persons who received AVA. Using a matched case-control study design, we assessed the relationship of RA and SLE with AVA vaccination using the Defense Medical Surveillance System. We identified potential cases using International Classification of Diseases, 9th Revision, Clinical Modification codes and confirmed cases with medical record review and rheumatologist adjudication. Using conditional logistic regression, we estimated odds ratios (OR) for AVA exposure during time intervals ranging from 90 to 1,095 days before disease onset. Among 77 RA cases, 13 (17%) had ever received AVA. RA cases were no more likely than controls to have received AVA when looking back 1,095 days (OR: 1.03; 95% confidence interval [CI]: 0.48-2.19) but had greater odds of exposure in the prior 90 days (OR: 3.93; 95% CI: 1.08-14.27). Among the 39 SLE cases, 5 (13%) had ever received AVA; no significant difference in receipt of AVA was found when compared with controls (OR: 0.91; 95% CI: 0.26-3.25). AVA was associated with recent onset RA, but did not increase the risk of developing RA in the long term.

Abstract
OBJECTIVE Overweight/obesity and anti-citrullinated protein antibodies (ACPA) increase rheumatoid arthritis (RA) risk. We investigated the relationship between body mass index (BMI) and ACPA, tested for an interaction between BMI and ACPA for RA risk, and examined effects of BMI and ACPA on time to RA diagnosis. DESIGN Within the Nurses' Health Studies, blood samples were collected before diagnosis from medical record-confirmed incident RA cases and matched controls. Multiplex assays measured 7 ACPA subtypes (biglycan, clusterin, enolase, fibrinogen, histone 2A, histone 2B, and vimentin). Logistic regression analyses tested the association of BMI and ACPA and for a multiplicative interaction between BMI groups (≥25 vs. <25kg/m2) and ACPA positivity (≥2 vs. <2 subtypes), adjusting for age, smoking, alcohol use, and HLA-shared epitope. In case-only analyses, log-rank tests compared time from blood draw to RA onset by cross-classified BMI/ACPA status. RESULTS Among 255 pre-RA cases and 778 matched controls, 15.7% vs. 2.1% (p<0.001) had ≥2 ACPA and 49.4% vs. 40.2% (p<0.01) were overweight/obese. Continuous BMI was not associated with presence of ≥2 ACPA [OR per kg/m2 unit BMI: 1.03 (95% CI: 0.97-1.09)]. However, there was a multiplicative interaction between elevated BMI and the presence of ≥2 ACPA for RA risk (p = 0.027). Women with BMI≥25kg/m2 and ≥2 ACPA had OR 22.7 (95% CI: 6.64-77.72) for RA. Median time to RA differed by BMI/ACPA group (overall log-rank p<0.001) and was shortest among women with ≥2 ACPA and BMI≥25kg/m2 [45.0 months, IQR: 17.5-72.5] and longest in women with <2 ACPA and BMI<25kg/m2 [125.0 months, IQR: 72.0-161.0] (pairwise log-rank p = 0.002). CONCLUSION Elevated BMI and presence of ACPA interacted to increase RA risk. Time to RA onset was shortest among overweight/obese women with ≥2 ACPA.

Abstract
Matrix metalloproteinases (MMPs) are zinc-dependent enzymes. These enzymes play a critical role in the destruction of articular cartilage in rheumatoid arthritis (RA), osteoarthritis (OA), psoriatic arthritis (PsA), and the spondyloarthropathies. MMP gene expression is upregulated in these synovial joint pathologies in response to elevated levels of proinflammatory cytokines and soluble mediators such as tumor necrosis factor-α, interleukin-1 (IL-1), IL-6, IL-17, and interferon-γ. These molecules are capable of activating the mitogen-activated protein kinase and Janus kinase/signal transducers and activators of transcription (JAK/STAT) pathways by binding the cytokine to their respective receptors on immune cells, macrophages, chondrocytes, synoviocytes, and osteocytes leading to increased synthesis of MMPs. Biologic drugs and/or small-molecule inhibitors designed to block cytokine to cytokine receptor interactions or to selectively inhibit JAKs have clinical efficacy in RA, PsA, and ankylosing spondylitis which correlated with a reduction in MMPs. Although there are currently no OA-selective drugs, it is likely that such a drug would have to reduce MMP gene expression to have clinical efficacy.

Abstract
Background Tong Luo Hua Shi (TLHS) is a new formulation of the traditional Tibetan medicine Wu-wei-gan-lu that has been used for the treatment of rheumatoid arthritis (RA) for hundreds of years in China. This study aimed to evaluate the efficacy and safety of TLHS in patients with RA. Methods This was a randomized, double-blind, placebo-controlled, dose-finding study performed in patients with active RA from five medical centers. Patients received three doses (4.8, 3.6, or 2.4 g/day po) of TLHS or placebo (tid po) for 8 weeks. Blood sampling, physical examination, and assessment of the American College of Rheumatology (ACR) 20 % improvement (ACR20) criteria were performed before and every 2 weeks after starting treatment. The primary endpoint was the ACR20. The secondary endpoints included safety. Results A total of 240 participants were screened and 236 patients were randomized (n = 59/group); 20 dropped out. After 8 weeks, ACR20 improvements in the TLHS 4.8 g and 3.6 g groups were significantly higher than in the placebo group (P < 0.01 and P < 0.05, respectively). ACR50 improvement in the TLHS 4.8 g group was significantly higher compared with the placebo group (P < 0.01). Symptoms of RA were significantly relieved in the TLHS groups. In the TLHS groups, insomnia (n = 1), gastroenteric reactions (n = 2), arrhythmia (n = 1), and minor hepatic lesion (n = 1) were reported; in the placebo group, hepatic dysfunction (n = 1) was reported (P = 0.878). Conclusions TLHS improved the symptoms of patients with RA according to the ACR20. Moreover, TLHS was safe. Trial registration Chinese Clinical Trial Registry: ChiCTR-TRC-12003871.

Abstract
Studies have reported the association of human leukocyte antigen (HLA) genes with susceptibility to develop actinic prurigo (AP) in Caucasians, but there were no studies in Asian populations, including the Chinese. Our study was performed to determine if AP is associated with susceptibility or protective HLA alleles or haplotypes in Singaporean Chinese. All Chinese patients diagnosed with AP at National Skin Center, Singapore, from January 2002 to April 2015 were invited to participate in the study. Clinical data and phototesting results were collated, and HLA typing was performed. Among 14 patients included, 11 were male and the mean age was 49.6 (37.9-61.3) years. All patients did not have a family history of AP and none had mucosal involvement, as such these clinical features differed from Caucasian AP patients. The frequency of DRB1*03:01 in AP patients was significantly higher compared to healthy controls (43% vs 16%, P = 0.022, odds ratio (OR) 3.89). Concurrently, the frequency of HLA-B*58:01-DRB1*03:01 haplotype was also significantly increased (25% vs 7%, P = 0.004, OR 4.23). In conclusion, HLA-DRB1*03:01 was associated with AP in Singaporean Chinese patients. This novel allelic association may possibly be utilized as a biological marker to aid in the diagnosis of AP in Chinese patients.

Abstract
Purpose/Background. Mounting evidence designates that HLA-G plays a role in the regulation of inflammatory processes and autoimmune diseases. There are controversial reports concerning the impact of HLA-G gene polymorphism on rheumatoid arthritis (RA). This study was aimed at examining the impact of 14 bp ins/del and +3142G>C polymorphism with susceptibility and early disease activity in RA patients in a sample of the Iranian population. Methods. This case-control study was done on 194 patients with RA and 158 healthy subjects. The HLA-G rs1063320 (+3142G>C) and rs66554220 (14 bp ins/del) variants were genotype by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFP) and PCR method, respectively. Results. The HLA-G +3142G>C polymorphism significantly decreased the risk of RA in codominant (OR = 0.61, 95% CI = 0.38-0.97, p = 0.038, GC versus GG; OR = 0.36, 95% CI = 0.14-0.92, p = 0.034, CC versus GG), dominant (OR = 0.56, 95% CI = 0.36-0.87, p = 0.011, GC + CC versus GG), and allele (OR = 0.58, 95% CI = 0.41-0.84, p = 0.004, C versus G) inheritance models tested. Our finding did not support an association between HLA-G 14 bp ins/del variant and risk/protection of RA. In addition, no significant association was found between the polymorphism and early disease activity. Conclusion. In summary, our results showed that HLA-G +3142G>C gene polymorphism significantly decreased the risk of RA in a sample of the Iranian population.

Abstract
INTRODUCTION Methotrexate (MTX) is used to treat cancers, several forms of arthritis and other rheumatic conditions, although MTX may cause pulmonary toxicity related to the production of free oxygen radicals, various cytokines. Infliximab (IB) with its potent effect on tumor necrosis factor-alpha (TNF-α) inhibition also inhibits the release of endothelin-1 (ET-1). We aimed to investigate whether IB reduces pulmonary damage induced by an overdose of MTX. METHOD The rats were divided into 3 groups of 8 animals. The control group was given only saline. One dose of 20mg/kg MTX intraperitoneal was administered in the MTX group. IB 7 mg/kg was given to the MTX+IB (MI) group. Three days after IB was administered, 20mg/kg MTX was given. Five days after MTX was administered, all rats were sacrificed. RESULTS The TNF-α, ET-1, malondialdehyde (MDA), myeloperoxidase (MPO) and caspase-3 levels in MTX group were significantly higher than in control groups of TNF-α (P=.001), ET-1 (P=.001), MDA (P=.001), MPO (P=.001) and caspase-3 levels (P=.001) and MI groups of TNF-α (P=.009), ET-1 (P=.001), MDA (P=.047), MPO (P=.007) and caspase-3 levels (P=.003). The MI group had less histopathological damage in lung tissue than the MTX group. CONCLUSION Overdose of MTX leads to cytokine release and the formation of reactive oxygen species in addition to increased ET-1 secretion release that causes lung damage. IB, as a potent proinflammatory agent, TNF-α blocker, can decrease ET-1 release and oxidative stress, it may show significant protective effects in lung tissue against damage caused by MTX overdose.

Abstract
Rheumatoid arthritis (RA) is an autoimmune disease that has a complex genetic basis. Therefore, it is important to explore the genetic background of RA. The extensive recent application of polymorphic genetic markers, especially single nucleotide polymorphisms, has presented us with a large quantity of genetic data. In this study, we developed the Database of Rheumatoid Arthritis-related Polymorphisms (RADB), to integrate all the RA-related genetic polymorphisms and provide a useful resource for researchers. We manually extracted the RA-related polymorphisms from 686 published reports, including RA susceptibility loci, polymorphisms associated with particular clinical features of RA, polymorphisms associated with drug response in RA and polymorphisms associated with a higher risk of cardiovascular disease in RA. Currently, RADB V1.0 contains 3235 polymorphisms that are associated with 636 genes and refer to 68 countries. The detailed information extracted from the literature includes basic information about the articles (e.g. PubMed ID, title and abstract), population information (e.g. country, geographic area and sample size) and polymorphism information (e.g. polymorphism name, gene, genotype, odds ratio and 95% confidence interval, P-value and risk allele). Meanwhile, useful annotations, such as hyperlinks to dbSNP, GenBank, UCSC, Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway, are included. In addition, a tool for meta-analysis was developed to summarize the results of multiple studies. The database is freely available at http://www.bioapp.org/RADB.

Abstract
BACKGROUND Juvenile idiopathic arthritis (JIA) of the temporomandibular joint (TMJ) can cause severe growth disturbances of the craniomandibular system. Antigen-induced arthritis (AIA) of the rabbit TMJ is simulating the inflammatory process of the TMJ in JIA. The aim of this study was to investigate the effect of a systemic administration of the tumor necrosis factor-alpha (TNF-α) antagonist etanercept on AIA in rabbits by means of three different histological staining methods. METHODS After sensitization, a bilateral arthritis of the TMJ was induced and maintained by repeated intra-articular administrations of ovalbumin in 12 New Zealand white rabbits aged 10 weeks. From the 13th week of age, 6 of the 12 rabbits received weekly subcutaneous injections of etanercept, and the other 6 animals remained without therapy. Another 6 animals served as controls, receiving no treatment or intra-articular injections at all. After euthanasia at the age of 22 weeks, all TMJs were retrieved en bloc. Sagittal sections were cut and stained with hematoxylin-eosin (H-E), Safranin-O for the evaluation of the Mankin score, and tartrate-resistant acid phosphatase (TRAP). RESULTS In the arthritis group, a chronic inflammation with degeneration of the articular cartilage was visible. In the etanercept group, the signs of cartilage degeneration were significantly reduced but present. In contrast, the joints in the control group were inconspicuous. A strong correlation between the Mankin score and TRAP-positive cells could be found. CONCLUSIONS Antigen-induced arthritis causes severe damage in the TMJ of young rabbits. An improvement seems to be achievable by a systemic administration of etanercept.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is a chronic inflammatory disease with many genetic factors predisposing to disease susceptibility. The aim of the present study was to investigate the impact of CD226 rs727088 and rs763361 polymorphisms and susceptibility to RA in a sample of the Iranian population. METHODS This case-control study was carried out on 100 patients with RA and 104 healthy subjects. The polymorphisms were determined using tetra amplification refractory mutation system-polymerase chain reaction assay. RESULTS The rs763361 (Gly307Ser) polymorphism increased the risk of RA in codominant, dominant and recessive-tested inheritance models (odds ratio [OR] = 3.18, 95% confidence intervals [95% CI] = 1.44-7.02, P = 0.004, CC vs. TT, and OR = 1.98, 95% CI = 1.10-3.57, P = 0.023, CC vs. CT-TT, and OR = 2.61, 95% CI = 1.26-5.37, P = 0.010, CC + CT vs. TT, respectively). In addition, the rs763361 T allele increased the risk of RA (OR = 2.06, 95% CI = 1.38-3.08, P<0.001). However, no significant difference was observed among the groups regarding CD226 rs727088 polymorphism (χ2 = 3.20, P = 0.202). CONCLUSIONS Our finding showed that CD226 rs763361, but not rs727088, gene polymorphism increased the risk of RA in a sample of the Iranian population.

Abstract
An association between human leukocyte antigen-DRβ1*04 and rheumatoid arthritis (RA) has been known for more than 25 years. It has been observed in many different populations, and it accounts for approximately one-third of the genetic component of RA susceptibility. Our aim was to study the distribution of HLA-DRβ1 alleles in well-characterized RA patients from Western India. Polymerase chain reaction-based sequence-specific oligonucleotide probing (PCR-SSOP) technique was used to identify HLA-DRβ1 alleles among 80 clinically well-defined patients and 90 normal controls from same ethnicity. A significant increase in the frequency of DRβ1*04 was observed among RA patients (PF% 30 vs. 7.7, OR 4.959, p value 0.00018), whereas DRβ1*03 and *14 were significantly decreased among patients when compared with controls (DRβ1*03, PF% 8.75 vs. 26.6, OR 0.2637, p value 0.00253; DRβ1*14, PF% 17.5 vs. 30.0, OR 0.4949, p value 0.05722). Our results suggest that DRβ1*04 was strongly associated with well-characterized RA patients from Western India, whereas DRβ1*03 and *14 may be protective alleles for RA. The identification of susceptible allele in patients with RA may help physician to make early decisions regarding initiation of early intensive therapy with disease modifying anti-rheumatic drugs and biological agents to decrease disability in RA patients.

Abstract
OBJECTIVES The objective of this study was to investigate the lipid profile and high sensitive C-reactive protein (hs-CRP) levels in rheumatoid arthritis (RA) patients, and compare them with healthy controls, and also compare the different patterns of these parameters during active RA between male and female patients. DESIGN AND METHODS We studied 60 RA patients and 65 controls matched by age and sex. All cases were selected from the Rheumatology Department of a tertiary care hospital, Delhi, India and fulfilled the 1987 American College of Rheumatology revised criteria for RA. RESULTS We found that male RA patients had significantly higher levels of hs-CRP (p<0.001), low density lipoprotein cholesterol (LDL-C)/high density lipoprotein cholesterol (HDL-C) (p<0.001), total cholesterol (TC)/HDL-C (p<0.05), and lower level of HDL-C (p<0.01), than male controls. The mean levels of HDL-C and TC were high (p<0.05), and LDL-C, LDL-C/HDL-C (p<0.01), and hs-CRP (p<0.001) were low in healthy females as compared to female RA patients. Between RA patients, females had significantly high level of HDL-C (p<0.001), and low levels of TC/HDL-C and LDL-C/HDL-C (p<0.001) as compared to RA males. Mean levels of TC and HDL-C were higher in healthy females (p<0.05) and triglyceride (TG) was lower (p<0.05) than in healthy males. CONCLUSIONS Results demonstrate that the RA patients have high levels of inflammatory marker hs-CRP and altered lipid profile, and these are affected by the gender of the RA patients. Lipid levels should be monitored and managed in patients with RA to minimize the long-term risk of cardiovascular disease.

Abstract
OBJECTIVE Suggested predictors of rheumatoid arthritis (RA) include environmental exposure, such as smoking. Our purpose was to investigate potential predictors of RA in a nested case-control study based on a prospective cohort. METHOD Between 1991 and 1996, 30,447 persons were included in the Malmö Diet and Cancer Study (MDCS). Individuals who developed RA after inclusion up to 31 December 2004 were identified by linking the database to different registers. Four controls were selected for every case. Data on lifestyle factors were collected in the MDCS. RESULTS We identified 172 incident cases of RA [36 men/136 women, mean age at diagnosis 63 years, 69% rheumatoid factor (RF) positive, median time from inclusion to diagnosis 5 (range 1-13) years]. In bivariate analyses, baseline smoking [odds ratio (OR) 2.02, 95% confidence interval (CI) 1.31-3.12] and a low level of formal education (i.e. ≤ 8 years; OR 2.42, 95% CI 1.18-4.93 vs. University degree) predicted subsequent development of RA. Infrequent baseline alcohol consumption was a predictor of RA (OR 3.47, 95% CI 1.91-6.30) compared to recent use (within the past month), and individuals with moderate baseline alcohol consumption (3.5-15.2 g/day vs. < 3.5 g/day) tended to have a reduced risk of RA (OR 0.48, 95% CI 0.22-1.05) in multivariate analyses, adjusted for smoking and level of education. CONCLUSIONS Smoking and a low level of formal education were found to be independent predictors of RA. Moderate alcohol consumption may also be associated with a reduced risk.

Abstract
Background Inconsistent results across association studies including Genome-wide association, have posed a major challenge in complex disease genetics. Of the several factors which contribute to this, phenotypic heterogeneity is a serious limitation encountered in modern medicine. On the other hand, Ayurveda, a holistic Indian traditional system of medicine, enables subgrouping of individuals into three major categories namely Vata, Pitta and Kapha, based on their physical and mental constitution, referred to as Prakriti. We hypothesised that conditioning association studies on prior risk, predictable in Ayurveda, will uncover much more variance and potentially open up more predictive health. Objectives and Methods Identification of genetic susceptibility markers by combining the prakriti based subgrouping of individuals with genetic analysis tools was attempted in a Rheumatoid arthritis (RA) cohort. Association of 21 markers from commonly implicated inflammatory and oxidative stress pathways was tested using a case-control approach in a total cohort comprising 325 cases and 356 controls and in the three subgroups separately. We also tested few postulates of Ayurveda on the disease characteristics in different prakriti groups using clinico-genetic data. Results Inflammatory genes like IL1β (C-C-C haplotype, p = 0.0005, OR = 3.09) and CD40 (rs4810485 allelic, p = 0.04, OR = 2.27) seem to be the determinants in Vata subgroup whereas oxidative stress pathway genes are observed in Pitta (SOD3 rs699473, p = 0.004, OR = 1.83; rs2536512 p = 0.005; OR = 1.88 and PON1 rs662, p = 0.04, OR = 1.53) and Kapha (SOD3 rs2536512, genotypic, p = 0.02, OR = 2.39) subgroups. Fixed effect analysis of the associated markers from CD40, SOD3 and TNFα with genotype X prakriti interaction terms suggests heterogeneity of effects within the subgroups. Further, disease characteristics such as severity was most pronounced in Vata group. Conclusions This exploratory study suggests discrete causal pathways for RA etiology in prakriti based subgroups, thereby, validating concepts of prakriti and personalized medicine in Ayurveda. Ayurgenomics approach holds promise for biomarker discovery in complex diseases.

Abstract
Methotrexate (MTX) is the most commonly used disease-modifying antirheumatic drug (DMARD) for the treatment of rheumatoid arthritis (RA). However, despite its efficacy and affordability, additional DMARDs or biologic agents are often required in order to achieve the recommended goals of low disease activity or remission. Although well tolerated by most, some patients develop important side effects such as cytopenias, gastrointestinal adverse events (stomatitis, nausea), or abnormal liver function tests, which may limit its use and may result in additional health care costs. Given the clinical implications of widespread use of MTX in RA, various studies have evaluated the role of potential biomarkers in predicting treatment effectiveness of MTX. These biomarkers include RBC MTX polyglutamate (PG) levels; genetic variation in genes from relevant biological and metabolic pathways; gene expression profiles; serum proteins. This paper provides an update on the current data regarding biomarkers of treatment response to MTX.

Abstract
A strong association between rheumatoid arthritis (RA) and human leukocyte antigen (HLA) has been observed in many different populations and that accounts for approximately one-third of the genetic component of RA susceptibility. The greatest effect comes from DRβ1 gene where the strongest association has been found with DRβ1*04 (DR4) allele. As serology has some disadvantages over polymerase chain reaction (PCR)-based techniques and commercially available PCR-based kits are expensive, this study was aimed to standardize simple in-house PCR-SSP technique. Accuracy of this test was further checked with standard PCR-SSOP (RLS) results. The frequency HLA-DRβ1*04 was significantly increased among RA patients when compared with normal controls. In this study, a very simple, convenient and more cost-effective in-house PCR-SSP technique was standardized for HLA-DRβ1*04 typing that is helpful to RA diagnosis in developing countries like India, which can be used as a good screening test.

Abstract
Dihydrofolate reductase (DHFR) catalyzes the reduction of dihydrofolate to tetrahydrofolate (THF). THF is needed for the action of folate-dependent enzymes and is thus essential for DNA synthesis and methylation. The importance of this reaction is demonstrated by the effectiveness of antifolate medications used to treat cancer by inhibiting DHFR, thereby depleting THF and slowing DNA synthesis and cell proliferation. Due to the pivotal role that DHFR plays in folate metabolism and cancer treatment, changes in the level of DHFR expression can affect susceptibility to a variety of diseases dependent on folate status such as spina bifida and cancer. Likewise, variability in DHFR expression can affect sensitivity to anti-cancer drugs such as the folate antagonist methotrexate. Alterations in DHFR expression can be due to polymorphisms in the DHFR gene. Several variations have recently been described in DHFR, including promoter polymorphisms, the 19-bp deletion allele and variations in 3’UTR. These polymorphisms seem to be functional, affecting mRNA levels through various interesting mechanisms, including regulation through RNA interference. Several groups have assessed the association of these polymorphisms with folate levels, risk of cancer and spina bifida as well as the outcome of diseases treated with MTX. The latter may lead to different treatment schedules, improving treatment efficacy and/or allowing for a reduction in drug side effects. This review will summarize present knowledge regarding the predictive potential of DHFR polymorphisms in disease and treatment.

Abstract
BACKGROUND AND OBJECTIVES Analysis of the role of different alleles of human leukocyte antigen (HLA) in rheumatoid arthritis (RA) patients is necessary in many populations and geographical areas. The aim of the present study was to investigate the frequency of HLA-DRB1 alleles in RA patients, comparing with that in control group in southeast Iran. DESIGN AND SETTING Case-control study of rheumatoid arthritis patients referred to rheumatology clinic at university hospital. PATIENTS AND METHODS The frequency of HLA-DRB1 alleles was determined in 79 RA patients and 93 healthy subjects in Zahedan, southeast Iran. HLA-DRB1 allele types were identified by polymerase chain reaction with sequence-specific primer (PCR-SSP). RESULTS The HLA-DRB1FNx0110 allele showed a significantly higher frequency in patients with RA (OR=2.698, 95% CI=1.087-6.699, P=.045), while the frequency of DRB1FNx0103 allele in these subjects was significantly lower than that in the control group (OR=0.447, 95% CI=0.2285-0.8729, P=.021). The frequencies of DRB1FNx0101, DRB1FNx0104, DRB1FNx0107, DRB1FNx0109, DRB1FNx0111, DRB1FNx0113, DRB1FNx0114, DRB1FNx0115, DRB1FNx0116 were not significantly different between RA subjects and the control group. CONCLUSION The data suggest that the DRB1FNx0110 allele is a risk factor and DRB1FNx0103 is protective for RA in this population.

Abstract
High myeloperoxidase (MPO) serum levels have been shown in several inflammatory diseases, including rheumatoid arthritis (RA). However, the correlation between MPO levels and disease activity in RA patients is still controversial. The aim of the study was to determine MPO plasma levels in RA patients and to investigate potential correlations between MPO levels and disease activity and treatment. MPO plasma levels were measured by ELISA according the manufacturer's instructions. Disease activity was measured by DAS28 ESR and DAS28 CRP scores, and patients were classified into 4 groups: group 1 DAS28 < 2.6; group 2: 2.6 ≤ DAS28 ≤ 3.2; group 3: 3.2 < DAS28 ≤ 5.1 and group 4: DAS28 > 5.1. Rheumatoid factor (RF) was measured by latex agglutination test, and anti-cyclic citrullinated peptide (anti-CCP) antibodies were detected by ELISA with a commercial kit. Fifty-seven female RA patients (mean age: 46.02 ± 13.47 years, mean disease duration: 115.77 ± 99.44 months) and sixty gender- and age-paired healthy controls were included. Mean MPO plasma levels were significantly higher in patients than in controls (72.27 pM vs. 40.78 pM, P = 0.007). RF was found in 59.6% and anti-CCP in 80.7% of the RA patients. No significant difference in MPO levels was seen among the four RA disease activity groups. We did not find significant correlation between MPO levels and disease activity as measured by DAS28 score. In conclusion, we observed significantly higher MPO plasma levels in RA patients when compared to healthy controls. However, we did not find correlation between MPO plasma level and disease activity.

Abstract
The influence of genetic factors in rheumatoid arthritis (RA) has been described, including several cytokine genes such as transforming growth factor β (TGF-β) with regulatory effects on lymphocytes, dendritic cells, macrophages, chondrocytes, and osteoblasts, which are important in the RA pathogenesis. The G915C TGF-β1 polymorphism has been associated with soluble TGF-β1 (sTGF-β) serum levels. Thus, we studied the association of G915C (Arg25Pro) TGF-β1 polymorphism with sTGF-β1 serum levels in RA. We enrolled 120 RA patients and 120 control subjects (CS). The G915C TGF-β1 polymorphism was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method, and sTGF-β1 serum levels were quantified using an ELISA kit. The genotype frequency of G915C TGF-β1 polymorphism in RA and CS was G/G (91.7%), G/C (8.3%), C/C (0%) and G/G (85.8%), G/C (14.2%), C/C (0%), respectively, without significant differences. Moreover, the G/G TGF-β1 genotype carriers presented the highest disability index evaluated for the Spanish HAQ-DI score (P < 0.001). In addition, the sTGF-β1 serum levels were higher in RA (182.2 ng/mL) than CS (160.2 ng/mL), there was not significant difference. However, we found a positive correlation between the sTGF-β1 serum levels and the functional class (r = 0.472, P = 0.023). In conclusion, the G915C (Arg25Pro) TGF-β1 polymorphism is not associated with RA, but the sTGF-β1 serum levels are related with the functional class in RA.

Abstract
Background MicroRNAs (miRNAs) are small RNAs that recognize and regulate mRNA target genes. Multiple lines of evidence indicate that they are key regulators of numerous critical functions in development and disease, including cancer. However, defining the place and function of miRNAs in complex regulatory networks is not straightforward. Systems approaches, like the inference of a module network from expression data, can help to achieve this goal. Methodology/Principal Findings During the last decade, much progress has been made in the development of robust and powerful module network inference algorithms. In this study, we analyze and assess experimentally a module network inferred from both miRNA and mRNA expression data, using our recently developed module network inference algorithm based on probabilistic optimization techniques. We show that several miRNAs are predicted as statistically significant regulators for various modules of tightly co-expressed genes. A detailed analysis of three of those modules demonstrates that the specific assignment of miRNAs is functionally coherent and supported by literature. We further designed a set of experiments to test the assignment of miR-200a as the top regulator of a small module of nine genes. The results strongly suggest that miR-200a is regulating the module genes via the transcription factor ZEB1. Interestingly, this module is most likely involved in epithelial homeostasis and its dysregulation might contribute to the malignant process in cancer cells. Conclusions/Significance Our results show that a robust module network analysis of expression data can provide novel insights of miRNA function in important cellular processes. Such a computational approach, starting from expression data alone, can be helpful in the process of identifying the function of miRNAs by suggesting modules of co-expressed genes in which they play a regulatory role. As shown in this study, those modules can then be tested experimentally to further investigate and refine the function of the miRNA in the regulatory network.

Abstract
Methotrexate (MTX) has been widely used for the treatment of inflammatory diseases and rheumatoid arthritis (RA), as well as a variety of tumors. However, MTX-induced toxicity is a serious and unpredictable side effect of this therapy and an important clinical problem. We used microarray analysis to examine MTX-induced gene expression in a human lung epithelial cell line (BEAS-2B) and identified 10 differentially expressed genes related to the p38 mitogen-activated protein kinase (MAPK) pathway, including IL-1beta, MKK6, and MAPKAPK2. Differential gene expression was confirmed via real-time RT-PCR. To determine the functional significance of MTX-induced p38 MAPK activation, we used a p38 MAPK inhibitor (SB203580) to block the p38 MAPK cascade. We also used protein array technology to investigate the modulated expression of pro- and anti-inflammatory cytokines in BEAS-2B cells. MTX activated IL-1beta expression and induced the phosphorylation of various proteins in the p38 MAPK cascade, including TAK1, MKK3/MKK6, p38 MAPK, MAPKAPK2, and HSP27. Finally, HSP27 activation may increase IL-8 secretion, resulting in a pulmonary inflammatory response such as pneumonitis. Although IL-1beta and IL-8 expression increased, the expression of IL-4, IL-6, IL-12, TNF-alpha, MIP-1alpha, and MIP-1beta decreased in a dose-dependent manner. These results suggest that the modulation of cytokine expression may play an important role in MTX-induced pulmonary toxicity.

Abstract
PURPOSE The pharmacology, pharmacokinetics, clinical efficacy, safety, and role of tocilizumab in rheumatoid arthritis (RA) are reviewed. SUMMARY Tocilizumab is a novel monoclonal antibody that competitively inhibits the binding of interleukin-6 (IL-6) to its receptor (IL-6R). Inhibiting the entire receptor complex prevents IL-6 signal transduction to inflammatory mediators that summon B and T cells. Tocilizumab has a nonlinear pharmacokinetic profile. The hypothesis that targeting and inhibiting IL-6R with tocilizumab can result in significant improvement of the signs and symptoms of RA appears to have been substantiated in one Phase III and two Phase II clinical trials, which have demonstrated a marked reduction in disease activity and the acute-phase response. The results of these studies indicate that tocilizumab treatment, both as a combination with methotrexate and as monotherapy, has a safety profile consistent with that of other biological and immunosuppressive therapies. In general, tocilizumab as monotherapy and in combination with methotrexate appears to be well tolerated. Adverse events were not dose dependent and were of similar frequency in all groups. Tocilizumab appears to provide an additional option for those patients who do not respond sufficiently to methotrexate. Since IL-6R inhibition has a distinct mechanism of action, some patients who do not respond to antitumor necrosis factor agents or who have a partial response may respond to tocilizumab. CONCLUSION Tocilizumab, a novel IL-6R inhibitor, may be beneficial for the treatment of RA in patients who do not respond to methotrexate or disease-modifying antirheumatic drugs. A large clinical trial is needed to confirm tocilizumab's clinical efficacy and safety.

Abstract
One of the hallmarks of arthritis is swollen joints containing unusually high quantities of hyaluronan. Intact hyaluronan molecules facilitate cell migration by acting as ligands for CD44. Hyaluronan degradation products, readily formed at sites of inflammation, also fuel inflammatory processes. Irrespective of whether viruses could be a cause of rheumatoid arthritis, there is clear evidence that links viral infections to this debilitating disease. For this study, live Epstein-Barr virus and a number of double- and single-stranded synthetic viral analogs were tested for their effectiveness as activators of hyaluronan (HA) synthesis. As shown herein, Epstein-Barr virus-treated fibroblast-like synoviocytes significantly increase HA production and release. Real time reverse transcription-PCR data show that HAS1 mRNA levels are significantly elevated in virus-treated cells, whereas mRNA levels for the genes HAS2 and HAS3 remain unchanged. As to the mechanism of virus-induced HAS1 transcription, data are presented that imply that among the double- and single-stranded polynucleotides tested, homopolymeric polycytidylic structures are the most potent inducers of HAS1 transcription and HA release, whereas homopolymeric polyinosinic acid is without effect. Analyses of virus-induced signal cascades, utilizing chemical inhibitors of MAPK and overexpressing mutated IKK and IkappaB, revealed that the MAPK p38 as well as the transcription factor NF-kappaB are essential for virus-induced activation of HAS1. The presented data implicate HAS1 as the culprit in unfettered HA release and point out targets in virus-induced signaling pathways that might allow for specific interventions in cases of unwanted and uncontrolled HA synthesis.

Abstract
BACKGROUND Adult rheumatoid arthritis (RA) patients are frequently clinically depressed. Peripheral inflammation in RA may influence neurotransmitter metabolism, neuroendocrine function, synaptic plasticity, as well as growth factor production, which can modify neural circuitry and contribute to depression. OBJECTIVE A convergence between pro-inflammatory cytokine-induced synovial joint inflammation in RA and the effects of pro-inflammatory cytokines on the brain may occur through activation of the stress-activated/mitogen-activated protein kinases (SAPK/MAPK) and/or Janus kinase/signal transducers and activators of transcription (JAK/STAT) pathways. METHODS The PubMed and Medlines databases were critically evaluated for evidence of SAPK/MAPK and/or JAK/STAT pathway activation in RA and depression. RESULTS/CONCLUSION Some novel anti-depression drugs that were employed in animal models of 'sickness behavior' and in human depression clinical trials suppressed clinical markers of inflammation, as well as SAPK/MAPK and/or JAK/STAT signaling in vitro. Modifying pro-inflammatory cytokine signaling pathways in the brain with antidepressants may also be useful in ameliorating peripheral inflammation in RA.

Abstract
The aims of this study were to summarize results on the association of HLA-DRB1 with rheumatoid arthritis (RA) in Asians and to determine if the shared epitope (SE) hypothesis could explain the meta-analysis results. Among the papers published between January 1987 and July 2006 on RA susceptibility in Asian-Mongoloid populations (Korean, Japanese, Chinese, and Thai), 12 were selected for the metaanalysis. Mongoloid-Asian patients with RA had significantly higher frequencies of HLA-DRB1*0101, *0401, *0410, and *1001 than controls (OR 1.5-2.1, p<0.05 for association). When analyses were restricted to more ethnically homogeneous populations, HLA-DRB1*0405 showed a significant susceptibility to RA in Koreans (OR 5.65, 95% CI 4.32-7.39), whereas the HLA-DRB1*0301, *0403, *0406, *0701, *1301, and *1405 alleles showed protective association with RA (OR 0.32-0.70, p<0.05 for association). In conclusion, it was found that HLA-DRB1 *0101, *0401, *0405, *0410, and *1001 are susceptible, while HLA-DRB1* 0301, *0403, *0406, *0701, *1301, and *1405 are protective in Asian-Mongoloids. All the RA-associated alleles except DRB1*0301 could be explained by the structural model supporting the SE hypothesis that RA susceptibility is determined by the combination of amino acid residues at HLA-DR beta71 and beta74, not by beta71 alone.

Abstract
We investigated the relationship between CAG and GGC repeat polymorphism of the androgen receptor (AR) gene and rheumatoid arthritis (RA) in female patients with different disease subtypes. This case-control study enrolled 215 women in three groups: RA patients refractory to standardized therapy (n = 51); RA patients at complete remission phase (n = 60); and healthy controls (n = 104). CAG and GGC repeat lengths were determined by automated fluorescence-based DNA fragment-sizing method. Demographic data, allele lengths, allele distribution, and zygosity status of CAG/GGC repeats were assessed for the three groups. Refractory RA patients tend to have a significantly younger onset age of RA and more elevated erythrocyte sedimentation rates than do remission RA patients. Mean and median values of CAG and GGC repeat lengths are similar in both RA and control patients. However, RA patients harboring any long CAG alleles with more than 23 repeats had an increased risk of a refractory course, whereas differences in risk were not observed between these patients and RA subtypes harboring any long GGC alleles with more than 16 repeats. In addition, the homozygous frequency of CAG but not GGC alleles was lower in refractory RA than in remission RA patients or in controls (p = 0.042). Neither CAG nor GGC repeat lengths had a significant relationship with rheumatoid factor reactivity. Our observations indicate that short CAG repeats of the AR gene with higher transactivation activity may have protective effects against refractory course of RA development and that homozygous frequency of CAG alleles may be involved in the disease remission subtype. In contrast, lack of association of GGC polymorphism and RA was also observed. Together, these data imply that CAG but not GGC alleles in the AR polymorphism may play an important role in modulating the disease pattern of RA among Taiwanese women.

Abstract
We investigated the distribution of HLA-DRB1 alleles in a sample of the Chinese Shantou population, and explored the relationship between HLA-DRB1 alleles and the susceptibility and clinical features of rheumatoid arthritis (RA). We studied 117 consecutive patients with RA and control groups, including 38 cases of systemic lupus erythematosus and 100 healthy individuals. HLA-DRB1 genotyping was performed using PCR with sequence-specific primers. HLA-DRB1*04 subtypes were detected using spot hybridization of PCR products with sequence-specific oligonucleotide probes. We compared the frequency of HLA-DRB1 alleles in healthy control patients with that in patients with RA. Patients with RA were evaluated for sex, age at disease onset, disease duration, extra-articular involvement, presence of autoantibodies, global functional status, and radiographic damage. The frequency of HLA-DRB1*04 was found to be significantly higher in RA patients than in healthy individuals (49.6% vs 18.0%, odds ratio = 4.478, P < 0.001). HLA-DRB1*0405 was the most prominently associated subtype in RA patients (62.1% vs 27.8%, odds ratio = 4.255, P = 0.011). Compared with the HLA-DRB1*04-negative RA group, the mean duration of RA in the HLA-DRB1*04-positive RA group was longer, and the mean age at disease onset was lower. A 2-9 year follow-up study was performed, and the risk factors associated with the radiographic progression of RA were determined. Logistic regression analysis revealed that only HLA-DRB1*04 alleles were significantly associated with the radiographic progression of RA (B = 2.652, P = 0.018, Exp(B) = 14.182). Our observations indicated that the HLA-DRB1*04 alleles, especially the subtype HLA-DRB1*0405, were significantly associated with RA susceptibility in the Chinese Shantou population. The HLA-DRB1*04 alleles may be associated with the severity of RA.

Abstract
Although broad agreement exists that genetic factors are important contributors to individual differences in pain sensitivity and risk for developing painful clinical conditions, the field of pain genetics is still in its infancy. This article reviews recent human studies of the genetics of acute and chronic pain, which implicate polymorphisms in genes coding for catechol-O-methyltransferase activity and micro-opioid receptors, among a number of others, as influential in explaining variability among the pain responses of individuals. Growing interest in pain genetics and accelerating methodologic advances in the field will almost certainly alter our understanding of which genes contribute to nociception and how dynamic interactions between multiple genes and environmental events shape the human experience of pain.

Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory arthritic and potentially disabling condition, mainly affecting women of middle age and having characteristic clinical features. Various microbial agents were implicated in the causation of RA. Extensive literature based on the results of various genetic, microbiological, molecular, and immunological studies carried out by independent research groups supports the role of Proteus mirabilis bacteria in the etiopathogenesis of RA. New diagnostic markers and criteria and the use of a novel therapeutic protocol in the form of antibiotic and dietary measures are suggested to be used together with current treatments in the management of RA. Prospective longitudinal studies with the use of antimicrobial measures in patients with RA are required to establish the therapeutic benefit of this microbe-disease association.
