26615612 Relationship between disease activity and hearing impairment in patients with rheumatoid a 2016 Feb The characteristics of hearing impairment (HI) in rheumatoid arthritis (RA) are still poorly understood, and their association with disease activity is based on conflicting information. This study compared HI between RA patients and controls and between active and remission RA groups using multi-frequency audiometry. This study enrolled 88 RA patients and 50 controls. The pure-tone hearing thresholds at 500 to 4000 Hz for air (AC) and bone (BC) conduction were compared between RA and controls as well as between active and remission RA patients using DAS28-CRP scores. The pure-tone hearing thresholds for AC and BC were significantly higher at high frequencies (2000 and 4000 Hz) in the RA group for both ears compared with controls. In addition, the BC threshold at 1000 Hz for the right ear was higher in the RA group than controls. When active and remission RA patients were compared, the thresholds were higher only at 4000 Hz for both ears for AC and BC in patients with active RA. The air-bone gap differed significantly at 2000 and 4000 Hz in both ears. This study demonstrated that patients with RA have a heightened risk of HI, and disease activity increases this risk, particularly at high frequencies. Clinicians who manage RA should be aware of HI and consider performing audiological evaluations in RA patients with active disease in particular.
27227821 Animal Models of Rheumatoid Arthritis (I): Pristane-Induced Arthritis in the Rat. 2016 BACKGROUND: To facilitate the development of therapies for rheumatoid arthritis (RA), the Innovative Medicines Initiative BTCure has combined the experience from several laboratories worldwide to establish a series of protocols for different animal models of arthritis that reflect the pathogenesis of RA. Here, we describe chronic pristane-induced arthritis (PIA) model in DA rats, and provide detailed instructions to set up and evaluate the model and for reporting data. METHODS: We optimized dose of pristane and immunization procedures and determined the effect of age, gender, and housing conditions. We further assessed cage-effects, reproducibility, and frequency of chronic arthritis, disease markers, and efficacy of standard and novel therapies. RESULTS: Out of 271 rats, 99.6% developed arthritis after pristane-administration. Mean values for day of onset, day of maximum arthritis severity and maximum clinical scores were 11.8±2.0 days, 20.3±5.1 days and 34.2±11 points on a 60-point scale, respectively. The mean frequency of chronic arthritis was 86% but approached 100% in long-term experiments over 110 days. Pristane was arthritogenic even at 5 microliters dose but needed to be administrated intradermally to induce robust disease with minimal variation. The development of arthritis was age-dependent but independent of gender and whether the rats were housed in conventional or barrier facilities. PIA correlated well with weight loss and acute phase reactants, and was ameliorated by etanercept, dexamethasone, cyclosporine A and fingolimod treatment. CONCLUSIONS: PIA has high incidence and excellent reproducibility. The chronic relapsing-remitting disease and limited systemic manifestations make it more suitable than adjuvant arthritis for long-term studies of joint-inflammation and screening and validation of new therapeutics.
24950169 Obstacles to the implementation of the treat-to-target strategy for rheumatoid arthritis i 2015 Jan OBJECTIVE: To clarify the obstacles preventing the implementation of the treat-to-target (T2T) strategy for rheumatoid arthritis (RA) in clinical practice. METHODS: A total of 301 rheumatologists in Japan completed a questionnaire. In the first section, participants were indirectly questioned on the implementation of basic components of T2T, and in the second section, participants were directly questioned on their level of agreement and application. RESULTS: Although nearly all participants set treatment targets for the majority of RA patients with moderate to high disease activity, the proportion who set clinical remission as their target was 59%, with only 45% of these using composite measures. The proportion of participants who monitored X-rays and Health Assessment Questionnaires for all their patients was 44% and 14%, respectively. The proportion of participants who did not discuss treatment strategies was 44%, with approximately half of these reasoning that this was due to a proportion of patients having a lack of understanding of the treatment strategy or inability to make decisions. When participants were directly questioned, there was a high level of agreement with the T2T recommendations. CONCLUSION: Although there was a high level of agreement with the T2T recommendations, major obstacles preventing its full implementation still remain.
26607275 Balneotherapy in rheumatoid arthritis-a systematic review. 2016 Aug Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease characterized by persistent inflammation of synovial joints with pain, often leading to joint destruction and disability, and despite intensive research, the cause of RA remains unknown. Balneotherapy-also called mineral baths or spa therapy-uses different types of mineral water compositions like sulphur, radon, carbon dioxin, etc. The role of balneotherapy is on debate; Sukenik wrote that the sulphur mineral water has special proprieties to rheumatologic diseases, including in the course of active inflammatory phases in RA. The aim of this review is to summarize the available evidence on the effects of balneotherapy on patients with rheumatoid arthritis. We have made a systematic search of the articles published from 1980 to 2014 on this topic in PubMed, Scopus, CRD, PEDro, Web of Science and Embase databases. We have followed the method set by the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA). These that have compared balneotherapy with other therapeutic modalities or with no intervention were considered. The inclusion criteria of these papers were randomized control trial (RCT); languages: English, French, Spanish, Italian and Portuguese; evaluation of efficacy (analysis of outcomes); use of natural mineral water baths; and participants with RA. A total of eight articles documenting RCTs were found and included for full review and critical appraisal involving a total of 496 patients. The studies selected highlighted an important improvement and statistically significant in several clinical parameters, in spite of their heterogeneity between the various studies. One study emphasized an important improvement on functional capacity up to 6 months of follow-up (FU). Some of the studies (std.) reveal an improvement on morning stiffness (5 std.), number of active joints (3 std.), Ritchie index (2 std.) and activities of daily living (2 std.) up to 3 months of FU. Three studies reveal the improvement on handgrip strength up to 1 month of FU. About pain (VAS), the three studies which evaluated this parameter were inconclusive about real significant improvement. Our tables summarize the published papers about this topic. Different authors emphasize the same problems: methodologies differing from study to study, treatment modalities, outcomes and their analysis. On the one hand, it is particularly difficult to have homogeneity on this population in all the parameters (patient's clinical heterogeneity, diverse clinical course of the disease, variety of the drugs), and on the other hand, natural mineral water composition is always unique with potential specific biological effects. This comprehensive review has revealed that there are very few published studies about the use of natural mineral water in RA. International multicentre studies, using the same methodologies, could be achieved by carrying the scientific arguments to support our clinical practice.
27830341 Serum progranulin levels in Hispanic rheumatoid arthritis patients treated with TNF antago 2017 Mar Since progranulin (PGRN) is a natural ligand of TNF receptors, we assessed whether serum PGRN levels predict and/or reflect responsiveness of RA patients to TNF-antagonist therapy. TNF-antagonist-naïve RA patients (N = 35) were started on TNF-antagonist therapy. At baseline and at follow-up visits, DAS28-ESR, DAS28-CRP, and CDAI were calculated, and venous blood was collected for serum PGRN determination. Disease activity and clinical response were based on EULAR criteria. Baseline serum PGRN levels varied considerably and correlated with ESR and CRP. DAS28-ESR, DAS28-CRP, and CDAI were greater in "PGRN-high" than in "PGRN-low". Baseline serum PGRN levels did not predict clinical responsiveness to TNF-antagonist therapy. Nevertheless, changes in serum PGRN levels at 274+ days following initiation of TNF-antagonist therapy correlated with changes in ESR, CRP, DAS28-ESR, DAS28-CRP, and CDAI. At this time, DAS28-ESR, DAS28-CRP, and CDAI in PGRN-high and PGRN-low equalized, but serum PGRN levels remained greater in PGRN-high than in PGRN-low. To our knowledge, the present report is the first prospective study to longitudinally assess changes in serum PGRN levels following initiation of TNF-antagonist therapy. Although pre-treatment serum PGRN levels may not predict clinical responsiveness to TNF-antagonist therapy, changes in serum PGRN levels correlate with changes in disease metrics over time. By inference, administration of PGRN may represent an effective therapeutic option for development in RA patients.
25731770 Immunoregulatory role of IL-35 in T cells of patients with rheumatoid arthritis. 2015 Aug OBJECTIVE: IL-35 is the most recently identified member of the IL-12 family. It consists of EBV-induced gene 3 (EBI3) and IL-12α chain p35. We investigated whether IL-35 enhances the in vitro immunosuppressive function of peripheral blood isolated from patients with RA. METHODS: Peripheral blood was harvested from 17 active and 10 inactive RA patients and IL-35 concentrations were quantified using an ELISA. An expression vector containing IL-35 with a FLAG tag at the carboxyl-terminus was constructed by covalently linking EBI3 and IL-12α (p35). The function of IL-35 was then evaluated in a suppression assay using T cells isolated from human RA patients with CD2, CD3 and CD28 antibodies. RESULTS: Serum IL-35 levels and the number of Treg were decreased significantly in patients with active RA. There was a significant correlation between serum IL-35 and the 28-joint DAS with ESR (DAS28-ESR) in patients with active RA. IL-35 treatment enhanced the regulatory function, suppressing the levels of inflammatory cytokines such as IL-17 and IFN-γ and the cellular growth of effector T cells stimulated by conjugation with CD2, CD3 and CD28. CONCLUSION: These data revealed that IL-35 might suppress T cell activation during the peripheral immune responses of RA. Therefore our data suggest that IL-35 might have multiple therapeutic targets.
25112484 The association between vibration and vascular injury in rheumatic diseases: a review of t 2015 Feb Vascular manifestations can be seen early in the pathogenesis of inflammatory rheumatic diseases. Animal experiments, laboratory and clinical findings indicated that acute or long-term vibration exposure can induce vascular abnormalities. Recent years, in addition to Raynaud's phenomenon (RP), vibration as a risk factor for other rheumatic diseases has also received corresponding considered. This review is concentrated upon the role of vibration in the disease of systemic sclerosis (SSc). In this review, we are going to discuss the main mechanisms which are thought to be important in pathophysiology of vascular injury under the three broad headings of "vascular", "neural" and "intravascular". Aspects on the vibration and vascular inflammation are briefly discussed. And the epidemiological studies related to vibration studies in SSc and other rheumatic diseases are taken into account.
26216186 Proficiency testing for the detection of anti-citrullinated protein antibody in China. 2015 Oct 23 BACKGROUND: Anti-citrullinated protein antibodies (ACPAs) are important for the detection of rheumatoid arthritis (RA). There are many laboratories to detect it in their routine work, but their performance is not displayed in China. To examine the performance of ACPA assays from all laboratories, it is necessary to organize a laboratory proficiency test (PT). METHODS: A panel of 5 samples, including 4 positive and 1 negative, was produced by the National Center for Clinical Laboratories, using serum derived from patients, then distributed to 271 clinical laboratories. Quantitative and qualitative results reported by the participating laboratories were compared. RESULTS: Overall, 80.97% (200/247) of the laboratories had eligible PT scores. Of the kits used, most ELISA and chemiluminescence kits had a high sensitivity and specificity. Regarding intra-assay discrepancy, the Roche and Abbott kit had a better variable coefficient. The ratios of the quantitative results to the kit-specific cut-off values were similar. CONCLUSION: Performance varied between laboratories. Reagents and methods are the most important factors. Other factors may affect the intra-assay discrepancy. The similar mean of ratios of the quantitative results to the kit-assigned cut-offs suggests that a national criterion is requisite. It is necessary to organize a PT to identify performances of different laboratories.
25187185 Disease characteristics and treatment patterns in veterans with rheumatoid arthritis and c 2015 Apr OBJECTIVE: To assess disease characteristics, disease activity, and treatment patterns in rheumatoid arthritis (RA) patients with comorbid hepatitis C virus (HCV) infection. METHODS: RA patients with concomitant HCV were identified within the Veterans Affairs Rheumatoid Arthritis Registry. HCV was defined as at least 1 diagnostic code present in medical record databases. Generalized estimating equations in linear regression models compared component and composite measures of disease activity between HCV-positive and HCV-negative patients over the study period, accounting for within-subject correlations. Similar analysis of pharmacy databases evaluated medication use within each group. RESULTS: Ninety-two of 1,706 registry participants (5.1%) were identified with concomitant HCV. At enrollment, HCV-positive patients were younger (mean ± SD 61.7 ± 7.1 years versus 67.5 ± 11.2 years; P < 0.001), more often African American (35% versus 15%; P < 0.001), and smokers (48% versus 26%; P < 0.001). In unadjusted and adjusted analyses incorporating all study visits, patient-reported outcomes (pain, tender joints, and patient global scores) were higher in HCV-positive patients, contributing to higher disease activity scores. There was no difference in physician-reported outcomes (swollen joints or physician global scores). HCV-positive patients had lower C-reactive protein levels (β -0.30 [95% confidence interval (95% CI) -0.53, -0.07], P = 0.01). Over all visits, HCV-positive patients were less likely to receive methotrexate (odds ratio [OR] 0.27 [95% CI 0.17, 0.40], P < 0.001), and more likely to receive prednisone (OR 1.41 [95% CI 1.02, 1.97], P = 0.04) and anti-tumor necrosis factor α (anti-TNFα) therapies (OR 1.51 [95% CI 1.04, 2.19], P = 0.03). CONCLUSION: RA patients with concomitant HCV have higher disease activity scores, driven primarily by higher patient-reported measures. HCV-positive patients were more likely to be treated with prednisone and anti-TNFα therapies and less likely to receive methotrexate compared to HCV-negative patients.
27373893 Components of treatment delay in rheumatoid arthritis differ according to autoantibody sta 2016 Oct OBJECTIVE: To determine whether time to treatment following symptom onset differs between RA patients according to autoantibody status. METHODS: A single-centre retrospective analysis of a UK early RA inception cohort was first undertaken to identify those components of the patient journey that differed by serological subtype. Data from a UK national audit of early inflammatory arthritis patients was accessed to replicate the key finding. RESULTS: A total of 173 RA patients were diagnosed over a 31-month period, of whom 80 (46%) were ACPA/RF double-seropositive (ACPA(+)/RF(+)), 53 (31%) ACPA(-)/RF(-), 17 (10%) ACPA(+)/RF(-) and 23 (13%) RF(+)/ACPA(-) Overall, ACPA(+)/RF(+) patients experienced significantly longer symptom duration before DMARD initiation. This was accounted for by delays in their presentation to primary care following symptom onset-a finding that was robustly confirmed in an independent dataset of 2192 UK early RA patients. In contrast, ACPA(-)/RF(-) patients were significantly more likely to experience delays in DMARD initiation after presenting to secondary care. CONCLUSION: Causes of treatment delays in early RA differ according to patients' autoantibody status. More insidious symptom onset and/or distinct health-seeking behaviours among ACPA(+)/RF(+) patients may contribute to late presentations in primary care, whereas ACPA(-)/RF(-) patients experience delayed diagnosis and treatment in secondary care. These observations inform the research agenda, potentially influencing the design of service delivery for early arthritis patients.
27692967 Review of head-to-head study designs in rheumatoid arthritis. 2016 Dec OBJECTIVE: Treatment options available to patients with rheumatoid arthritis (RA) are ever-changing, and understanding the similarities and differences of efficacy and safety between different RA therapies is of key importance in order to facilitate treatment decisions by both the patient and physician. Very few head-to-head, peer-reviewed trials exist; instead, evidence for efficacy of treatments is often ascertained from placebo-controlled trials, registries and meta-analyses, which often do not sufficiently address the relative effectiveness of two medications. METHODS: A targeted review of indirect comparison methods, and ongoing and published clinical studies assessing the efficacy and safety, and the comparative efficacy and safety of biologic disease modifying antirheumatic drugs in RA. RESULTS: Critical elements that should be considered when designing head-to head trials are described using examples of true head-to-head and placebo-controlled randomized controlled trials (RCTs). The appropriate use of head-to-head trial designs is demonstrated by reviewing different examples of well-designed clinical trials, and an overview is presented of the challenges associated with indirect comparisons. This review also examines the use of studies comparing therapies to placebo, highlighting the difficulties associated with the interpretation of these studies. CONCLUSIONS: For comparative trials to contribute to evidence-based decision making in the treatment of RA, patient populations and treatment regimens as similar as possible to those used in routine clinical practice should be employed and the trial should be appropriately designed to answer the specific question asked.
25249238 Systematic review and meta-analysis of effects of foot orthoses on pain and disability in 2015 PURPOSE: This meta-analysis examined the effects of foot orthoses (FO) on pain and disability in rheumatoid arthritis (RA) patients. METHODS: MEDLINE, Cochrane Controlled Trials Register, EMBASE, SPORT Scielo, and CINAHL were searched through July 2014 for randomized controlled trials (RCTs) examining the effects of orthoses on pain and disability in RA patients. Two reviewers selected studies independently. Weighted mean differences (WMDs) and 95% confidence intervals (CIs) were calculated, and heterogeneity was assessed using the I(2) test. RESULTS: Three studies, involving 110 patients who received FO and 108 control patients, met the study criteria. Relative to controls, FO had a positive impact on pain (WMD 0.40; 95% CI 0.04-0.57). Between group differences in disability were not statistically significant. CONCLUSIONS: FO may improve pain in RA patients, but their impact on disability remains undetermined. Additional large RCTs are needed to investigate the effects of these devices in RA patients. Implications for Rehabilitation The use of foot orthoses (FO) often part of the conservative treatment of patients with rheumatoid arthritis (RA). However, the indication of these devices is usually empiric. Thus, the results of this meta-analysis can provide guidance to rehabilitation professionals to undertake these devices to therapeutic programs. There is no consensus among rehabilitation professionals regarding the efficacy of FO improved pain and disability in patients with RA. The results of this meta-analysis suggest that the use of the FO improves pain but has no impact on disability. Thus, rehabilitation professionals, from reading this article will make clear to their patients that benefit of the FO is exclusively in pain improvement. Healthcare professionals and organizations should take into account the costs of production of FO during the definition of the therapeutic program. In case of low cost, the effect on improvement of pain in the feet can justify the indication of these devices to a patient with RA.
26209213 Development of a multimorbidity index: Impact on quality of life using a rheumatoid arthri 2015 Oct OBJECTIVE: To develop a multimorbidity index (MMI) based on health-related quality of life (HRQol). METHODS: The index was developed in an observational RA cohort. In all, 40 morbidities recommended as core were identified using ICD-9 codes. MMIs of two types were calculated: one by enumerating morbidities (MMI.count) and the other by weighting morbidities based on their association with HRQol as assessed by EQ-5D in multiple linear regression analysis (using β-coefficients; MMI.weight). MMIs were compared to the Charlson comorbidity index (CCI) and externally validated in an international RA cohort (COMORA Study). RESULTS: In all, 544 out of 876 patients were multimorbid. MMI.count was in the range 1-16 (median = 2) and MMI.weight in the range 0-38 (median = 1). Both indices were more strongly associated with EQ-5D than CCI (Spearman: MMI.count = -0.20, MMI.weight = -0.26, and CCI = -0.10; p < 0.01). R(2) obtained by linear regression using EQ-5D as a dependent variable and various indices as independent variables, adjusted for age and gender, was the highest for MMI (R(2): MMI.count = 0.05, MMI.weight = 0.11, and CCI = 0.02). When accounting for clinical disease activity index (CDAI) R(2) increased: MMI.count = 0.18, MMI.weight = 0.22, and CCI = 0.17, still showing higher values of MMI compared with CCI. External validation in different RA cohorts (COMORA, n = 3864) showed good performance of both indices (linear regression including age, gender, and disease activity R(2) = 0.30 for both MMIs). CONCLUSION: In our cohort, MMI based on EQ-5D performed better than did CCI. Findings were reproducible in another large RA cohort. Not much improvement was gained by weighting; therefore a simple counted index could be useful to control for the effect of multimorbidity on patient's overall well-being.
27841031 Improving B-cell depletion in systemic lupus erythematosus and rheumatoid arthritis. 2017 Jul Rituximab-based B-cell depletion (BCD) therapy is effective in refractory rheumatoid arthritis (RA) and although used to treat patients with refractory systemic lupus erythematosus (SLE) in routine clinical practice, rituximab failed to meet the primary endpoints in two large randomised controlled trials (RCTs) of non-renal (EXPLORER) and renal (LUNAR) SLE. Areas covered: We review how BCD could be improved to achieve better clinical responses in RA and SLE. Insights into the variability in clinical response to BCD in RA and SLE may help develop new therapeutic strategies. To this end, a literature search was performed using the following terms: rheumatoid arthritis, systemic erythematosus lupus, rituximab and B-cell depletion. Expert commentary: Poor trial design may have, at least partly, contributed to the apparent lack of response to BCD in the two RCTs of patients with SLE. Enhanced B-cell depletion and/or sequential therapy with belimumab may improve clinical response at least in some patients with SLE.
26508519 Anti-rheumatoid arthritic effects of Saussurea involucrata on type II collagen-induced art 2016 Feb Saussurea involucrata (SI) has long been used under the herbal name "snow lotus" for treatment of inflammation and pain-related diseases in traditional Chinese medicine. The present study aimed to evaluate the pharmacological effects of SI on collagen II (CII)-induced arthritis in rats. Rats with collagen II (CII)-induced arthritis were orally administered SI (420 mg kg(-1)) for 40 consecutive days. Histopathological examination indicated that SI alleviates infiltration of inflammatory cells and synovial hyperplasia and slows joint destruction. SI intervention reduced the serum levels of RF, COMP, CRP and anti-CII IgG. Results also showed that SI is a potential therapeutic agent for alleviating the severity of the disease based on the reduced arthritic index. It was concluded that SI can ameliorate inflammation and joint destruction in CIA rats.
26197989 Disseminated histoplasmosis partially mimicking a dermatomyositis in a patient with rheuma 2015 Sep Histoplasma capsulatum var. capsulatum is a dimorphic fungus endemic to America and subtropical regions. Several cases of this opportunist mycosis have been reported in immunocompromised patients. We report the case of a patient treated with methotrexate and corticosteroid therapy for rheumatoid arthritis and who presented with disseminated histoplasmosis that partially mimicked a dermatomyositis.
27769224 Barriers and facilitators to disease-modifying antirheumatic drug use in patients with inf 2016 Oct 21 BACKGROUND: Although disease-modifying anti-rheumatic drugs (DMARDs) are the cornerstone of treatment for inflammatory rheumatic diseases, medication adherence to DMARDs is often suboptimal. Effective interventions to improve adherence to DMARDs are lacking, and new targets are needed to improve adherence. The aim of the present study was to explore patients' barriers and facilitators of optimal DMARD use. These factors might be used as targets for adherence interventions. METHODS: In a mixed method study design, patients (n = 120) with inflammatory arthritis (IA) completed a questionnaire based on an existing adapted Theoretical Domains Framework (TDF) to identify facilitators and barriers of DMARD use. A subgroup of these patients (n = 21) participated in focus groups to provide insights into their facilitators and barriers. The answers to the questionnaires and responses of the focus groups were thematically coded by three researchers independently and subsequently categorized. RESULTS: The barriers and facilitators that were reported by IA patients presented large inter-individual variations. The identified barriers and facilitators could be captured in the following domains based on an adapted TDF: (i) knowledge, (ii) emotions, (iii) attention, memory, and decision processes, (iv) social influences, (v) beliefs about capability, (vi) beliefs about consequences, (vii) motivation and goals, (viii) goal conflict, (ix) environmental context and resources, and (x) skills. CONCLUSIONS: Patients with IA have a variety of barriers and facilitators with regard to their DMARD use. All of these barriers and facilitators could be categorized into adapted domains of the TDF. Interventions that address individual facilitators and barriers, based on capability, opportunity, and motivation, are needed to develop strategies for medication adherence that are tailored to individual patient needs.
26054200 [Effect of electroacupunctu-e intervention on serum IL-17 and IL-23 contents in rheumatoid 2015 Apr OBJECTIVE: To observe the influence of electroacupuncture (EA) stimulation of "Zusanli" (ST 36) and "Kunlun" (BL 60) on serum and knee-joint IL-17 and IL-23 contents in rheumatoid arthritis (RA) rats so as to study its underlying mechanism in improving RA. METHODS: Male Wistar rats were randomly allocated to normal control, RA model, EA and Prednisolone groups (n = 8 in each group). The RA model was established by intra-planta injection of incomplete Freund's adjuvant and type II collagen. EA (2 Hz/100 Hz,1-2 mA)was applied to bilateral "Zusanli"(ST 36) and "Kunlun"(BL 60) for 30 min, once daily for 10 days. The rats' ankle diameter was measured, and IL-17 and IL-23 contents in the serum and the knee-joint cavity were assayed by ELISA and Western blot, respectively. RESULTS: In comparison with the normal control group, the rats' ankle diameter, serum IL-17 and IL-23 contents and knee-joint IL-17 and IL-23 protein expression levels were significantly increased in the model group (P < 0.05). After EA and Prednisolone treatment, compared with the model group, all the rats' ankle diameter, serum IL-17 and IL-23 contents and knee-joint IL-17 and IL-23 protein expression levels were decreased remarkably (P < 0.05). No obvious differences were found between the EA and Prednisolone groups in the aforementioned indexes (P > 0.05), except IL-17 protein expression level (being markedly lower in the Prednisolone group than in the EA group). CONCLUSION: EA intervention can reduce inflammatory reaction of the ankle-joint in RA rats, which may be related to its effects in down-regulating serum and knee-joint IL-17 and IL-23 levels.
26786168 [Disease-modifying antirheumatic drugs in rheumatoid arthritis patients with a history of 2016 Feb BACKGROUND: Cells of the adaptive immune system are relevant for the anti-tumor immune response; therefore, the basal therapy with disease-modifying antirheumatic drugs (DMARD) in rheumatoid arthritis patients with a history of gastrointestinal cancer must be carefully considered. OBJECTIVE: This article presents the evidence regarding colorectal cancer (CRC) and rheumatoid arthritis. METHOD AND RESULTS: The article is based on a PubMed search as well as a search in congress abstracts of the European League Against Rheumatism (EULAR) and the American College of Rheumatology (ACR). Current recommendations regarding screening and follow-up of CRC are summarized for clinically active rheumatologists. The current status of therapy and future therapeutic options are presented. The lower incidence of CRC in rheumatoid arthritis (RA) patients and the incidence under treatment with various DMARDs are described. The treatment options for RA patients in different tumor situations, e.g. during cytostatic therapy, palliative and curative situations are discussed, as well as the available evidence. In spite of the unsatisfactory level of evidence, conclusions and practical considerations for use by rheumatologists in clinical practice are discussed.
27682325 Differences between serum polar lipid profiles of male and female rheumatoid arthritis pat 2016 Dec OBJECTIVE: As there are pharmacological differences between males and females, and glucocorticoid (GC) treatment is associated with increased cardiovascular mortality rate in rheumatoid arthritis (RA) patients, it is important to study serum polar lipid profiles of male and female patients in response to GC therapy. Gender differences may require an adjustment to the treatment strategy for a selection of patients. METHODS: Serum samples from 281 RA patients were analysed using a targeted lipidomics platform. The differences in GC use and gender on polar lipid profiles were cross sectionally examined by multiple linear regressions, while correcting for confounding factors. RESULTS: Differences in polar lipids between GC users and non-GC users in females and males were merely restricted to lysophospholipids (lysophosphatidylcholines and lysophosphatidylethanolamines). Lysophospholipids in female patients treated with GCs were significantly higher than female patients not treated with GCs (p = 6.0 E-6), whereas no significant difference was observed in male GC users versus non-users (p = 0.397). CONCLUSION: The lysophospholipid profiles in response to GCs were significantly different between male and female RA patients, which may have implications for the cardiovascular risk of GC treatment.
