25746669 A retrospective study of clinical characteristics of interstitial lung disease associated 2015 Mar 7 BACKGROUND: Interstitial lung disease (ILD) in rheumatoid arthritis (RA) is associated with a poor prognosis. The purpose of this study was to assess the characteristics of ILD that are associated with RA. MATERIAL AND METHODS: This was a retrospective study of 544 Chinese patients with RA (427 women and 117 men). RA-ILD was diagnosed by high-resolution computed tomography (HRCT). Patients with RA-ILD or with RA alone were compared in terms of age, sex distribution, duration of disease, clinical and laboratory parameters, history of smoking, and medication. RESULTS: Based on HRCT imaging, 83 (15.26%) patients with RA were diagnosed with ILD. ILD was more frequent in older patients (59.60±9.66 vs. 50.54±13.76 years, P<0.001), in those with a longer duration of disease (7.46±7.40 vs. 5.27±6.32 years, P=0.013) and in male patients (34.9% vs. 19.1%, P=0.001). RA-ILD was found to be associated with hepatitis B surface antigen (HBsAg) positivity (odds ratio [OR]=2.56, 95% confidence interval [95% CI] 1.02-6.43) and smoking (OR=3.38, 95% CI 1.65-6.95). Higher levels of C-reactive protein (OR=3.59, 95% CI 1.58-8.15), anti-cyclic citrullinated peptide (CCP) (OR=2.24, 95% CI 2.09-4.13), and rheumatoid factor (OR=3.72, 95% CI 1.56-8.86) were detected in association with RA-ILD. RA-ILD was more frequently observed in patients treated with steroids (OR=1.91, 95% CI 1.18-3.09) or Tripterygium wilfordii (OR=2.56, 95% CI 1.21-5.40). Age (OR=2.20, 95% CI 1.04-4.65), age at RA onset (OR=2.55, 95% CI 1.11-5.90), anti-CCP (OR=2.47, 95% CI 1.19-5.17), and steroid use (OR=1.83, 95% CI 1.04-3.20) were independently associated with RA-ILD in multivariate analysis. CONCLUSIONS: RA-ILD was associated with age, age at RA onset, anti-CCP, and steroid use. Anti-CCP antibodies might be important biomarkers of RA-ILD.
27269294 Intravenous administration of expanded allogeneic adipose-derived mesenchymal stem cells i 2017 Jan OBJECTIVES: To evaluate the safety and tolerability of the intravenous administration of Cx611, a preparation of allogeneic expanded adipose-derived stem cells (eASCs), in patients with refractory rheumatoid arthritis (RA), as well as to obtain preliminary clinical efficacy data in this population. METHODS: It is a multicentre, dose escalation, randomised, single-blind (double-blind for efficacy), placebo-controlled, phase Ib/IIa clinical trial. Patients with active refractory RA (failure to at least two biologicals) were randomised to receive three intravenous infusions of Cx611: 1 million/kg (cohort A), 2 million/kg (cohort B), 4 million/kg (cohort C) or placebo, on days 1, 8 and 15, and they were followed for therapy assessment for 24 weeks. RESULTS: Fifty-three patients were treated (20 in cohort A, 20 in cohort B, 6 in cohort C and 7 in placebo group). A total of 141 adverse events (AEs) were reported. Seventeen patients from the group A (85%), 15 from the group B (75%), 6 from the group C (100%) and 4 from the placebo group (57%) experienced at least one AE.Eight AEs from 6 patients were grade 3 in intensity (severe), 5 in cohort A (lacunar infarction, diarrhoea, tendon rupture, rheumatoid nodule and arthritis), 2 in cohort B (sciatica and RA) and 1 in the placebo group (asthenia). Only one of the grade 3 AEs was serious (the lacunar infarction). American College of Rheumatology 20 responses for cohorts A, B, C and placebo were 45%, 20%, 33% and 29%, respectively, at month 1, and 25%, 15%, 17% and 0%, respectively, at month 3. CONCLUSIONS: The intravenous infusion of Cx611 was in general well tolerated, without evidence of dose-related toxicity at the dose range and time period studied. In addition, a trend for clinical efficacy was observed. These data, in our opinion, justify further investigation of this innovative therapy in patients with RA. TRIAL REGISTRATION NUMBERS: EudraCT: 2010-021602-37; NCT01663116; Results.
27698105 The Role of High-resolution Peripheral Quantitative Computed Tomography as a Biomarker for 2016 Oct Since 2011, members of the SPECTRA Collaboration (Study grouP for xtrEme-Computed Tomography in Rheumatoid Arthritis) have investigated the validity, reliability, and responsiveness of high-resolution peripheral quantitative computed tomography (HR-pQCT) as a biomarker for joint damage in inflammatory arthritis. Presented in this series of articles are a systematic review of HR-pQCT-related findings to date, a review of selected images of cortical and subchondral trabecular bone of metacarpophalangeal (MCP) joints, results of a consensus process to standardize the definition of erosions and their quantification, as well as an examination of the effect of joint flexion on width and volume assessment of the joint space.
27311198 [Pregnancy and lactation in rheumatoid arthritis]. 2016 Jun Previously, female RA patients wishing to become pregnant were treated with only glucocorticoid, NSAIDs and sulfasalazine. However, these limited therapy sometimes fail to sustain RA remission, though pregnancy in most cases is associated with improving RA activity. High RA activity and relative high dose of glucocorticoid also involved poor fertility. Recently, a variety of medications are available to treat patients with RA. This article reviewed the safety or not safety of these medications during prior to conception, pregnancy and post-partum period. Accumulating experience with TNF blockade provide the useful insights for the treatment of RA patients during pre-conception, pregnancy or lactation.
25948343 The rate of decrease in the disease activity of rheumatoid arthritis during treatment with 2015 OBJECTIVE: The aim of this study was to analyze the efficacy of adalimumab (ADA) in patients with rheumatoid arthritis treated with or without methotrexate (MTX) and determine impact of the MTX dose. METHODS: Pearson's product-moment correlation coefficient was used to assess the correlations between the improvement in the Disease Activity Score (DAS) 28- erythrocyte sedimentation rate (ESR) score and the MTX dose in patients receiving treatment with MTX at a dose of <8 mg/week, 8 mg/week and >8 mg/week. PATIENTS: ADA therapy was initiated in 68 rheumatoid arthritis patients between July 2008 and June 2013. The mean MTX dose was 9.6 ± 2.6 mg/week, and the patients were followed for 24 weeks. RESULTS: The mean DAS28-ESR scores at baseline and week 24 were 4.6 ± 1.3 and 2.7 ± 1.2 in the 60 patients treated with MTX and 4.5 ± 1.0 and 4.2 ± 1.5 in the eight patients treated without MTX, respectively. Clinical remission was achieved in 48% and 25% of the patients, respectively, by week 24. Moreover, 90.0% of the patients taking MTX continued to receive ADA until week 24, while 50.0% of the patients not taking MTX continued to receive ADA until week 24. Among the 35 patients receiving MTX at a dose of >8 mg/week, the DAS28-ESR scores decreased rapidly from 4.4 ± 1.2 at baseline to 3.2 ± 1.1 at week 4 and further decreased to 2.4 ± 1.0 at week 24. Meanwhile, clinical remission was achieved in 57% of the patients receiving MTX at a dose of >8 mg/week and 36% of those receiving MTX at a dose of ≤8 mg/week. A significant correlation was noted between the improvement in the DAS-ESR score and the MTX dose. CONCLUSION: In this study population, enhanced clinical efficacy of ADA was achieved in combination with the administration of a sufficient dose of MTX, determined to be >8 mg/week.
25857501 Efficacy & safety evaluation of Ayurvedic treatment (Ashwagandha powder & Sidh Makardhwaj) 2015 Jan BACKGROUND & OBJECTIVES: In the traditional system of medicine in India Ashwagandha powder and Sidh Makardhwaj have been used for the treatment of rheumatoid arthritis. However, safety and efficacy of this treatment have not been evaluated. Therefore, the present study was carried out to evaluate the efficacy and safety of Ayurvedic treatment (Ashwagandha powder and Sidh Makardhwaj) in patients with rheumatoid arthritis. METHODS: One hundred and twenty five patients with joint pain were screened at an Ayurvedic hospital in New Delhi, India. Eighty six patients satisfied inclusion criteria and were included in the study. Detailed medical history and physical examination were recorded. Patients took 5g of Ashwagandha powder twice a day for three weeks with lukewarm water or milk. Sidh Makardhwaj (100 mg) with honey was administered daily for the next four weeks. The follow up of patients was carried out every two weeks. The primary efficacy end point was based on American College of Rheumatology (ACR) 20 response. Secondary end points were ACR50, ACR70 responses, change from baseline in disease activity score (DAS) 28 score and ACR parameters. Safety assessments were hepatic function [alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), bilirubin and ß2 microglobulin], renal function (urea and creatinine and NGAL) tests and urine mercury level. RESULTS: The study was completed by 90.7 per cent (78/86) patients. Patients with moderate and high disease activity were 57.7 per cent (45/78) and 42.3 per cent (33/78), respectively. All patients were tested positive for rheumatoid factor and increased ESR level. Ashwagandha and Sidh Makardhwaj treatment decreased RA factor. A significant change in post-treatment scores of tender joint counts, swollen joint counts, physician global assessment score, patient global assessment score, pain assessment score, patient self assessed disability index score and ESR level were observed as compared to baseline scores. ACR20 response was observed in 56.4 per cent (44/78) patients (American College of Rheumatology criteria) and moderate response in 39.74 per cent (31/78) patients [European League Against Rheumatism (EULAR) criteria]. Ayurvedic treatment for seven weeks in rheumatoid arthritis patients showed normal kidney and liver function tests. However, increased urinary mercury levels were was observed after treatment. INTERPRETATION & CONCLUSIONS: The findings of the present study suggest that this Ayurvedic treatment (Ashwagandha powder and Sidh Makardhwaj) has a potential to be used for the treatment of rheumatoid arthritis. However, due to small sample size, short duration, non randomization and lack of a control group as study limitations, further studies need to be done to confirm these findings.
26938156 Non-autoimmune combined factor XIII A and B subunit deficiencies in rheumatoid arthritis p 2016 Apr INTRODUCTION: Coagulation factor XIII (FXIII) is a plasma fibrin-stabilizing factor comprising A and B subunits (FXIII-A and FXIII-B, respectively) in the form of a heterotetramer (FXIII-A2B2). A humanized monoclonal antibody to the interleukin-6 receptor (tocilizumab, TCZ) has emerged as an effective treatment for rheumatoid arthritis (RA), because it drastically reduces the inflammation of RA. We previously reported that two TCZ-treated RA patients with acquired FXIII deficiency developed pelvic hemorrhage. METHODS: Because TCZ treatment had been shown to be related to low FXIII ammonia release activity and FXIII antigen in the two RA cases, we further examined FXIII-related parameters in 36 TCZ-treated RA patients and compared to 29 healthy controls by employing functional and immunologic assays for FXIII. RESULTS: FXIII-A antigen and FXIII amine incorporation and ammonia release activities were significantly lower in the TCZ-treated group than the control group. The TCZ-treated group also showed mildly low FXIII-A2B2 and FXIII-B levels, and their fibrinogen levels were the lower limit of normal. A significant correlation between FXIII-B and fibrinogen was observed in the control and the TCZ groups, suggesting a common metabolic mechanism(s) for these two hepatic proteins. Because the specific activities of FXIII were normal and neither anti-FXIII-A nor anti-FXIII-B antibody was detected, the overall low FXIII level may have resulted from its impaired synthesis under an unbalanced cytokine milieu caused by TCZ treatment. CONCLUSION: Concomitant deficiencies in multiple hemostatic factors, including FXIII, may lead to an increased risk for hemorrhage in TCZ-treated RA patients.
24980067 Vitamin D levels and bone mass in rheumatoid arthritis. 2015 Mar Rheumatoid arthritis (RA) is a chronic systemic inflammatory autoimmune disease with high prevalence of osteoporosis. Previous evidence indicates an association between vitamin D deficiency and autoimmune diseases. The aim of this study was to evaluate serum 25 hydroxyvitamin D [25(OH)D] levels, bone mineral density (BMD) and disease activity in RA patients living in Argentina. We studied 34 RA women and 41 healthy women as a control group. RA patients had lower 25(OH)D levels (20.4 ± 0.9 ng/ml) than controls (26.3 ± 1.9 ng/ml; p < 0.05). No significant differences were found in lumbar spine BMD between premenopausal (preM) or postmenopausal (postM) patients, but femoral neck BMD was significantly lower in postM RA patients (T score -2.5 ± 0.4) than in postM control subjects (T score -0.9 ± 0.3, p = 0.014). Although no linear correlation between 25(OH)D levels and disease activity (DAS-28) was found, patients with moderate-high disease activity had lower 25(OH)D levels than those with low disease activity: DAS-28 >3.2: 19.5 ± 0.88 ng/ml; DAS-28 ≤3.2: 23.7 ± 2.8 ng/ml (p = 0.047). After 1 year of vitamin D treatment 25(OH)D levels were increased while DAS-28 were decreased (n = 25; p < 0.05). We conclude that patients with RA had lower 25(OH)D levels than the control group. Low levels of 25(OH)D were associated with moderate-high disease activity suggesting the importance of optimal 25(OH)D levels in RA patients. Femoral neck BMD was lower in postM RA patients. No differences in lumbar BMD were found between preM and postM RA patients, suggesting that bone mass evaluation in RA patients should include femoral neck BMD regardless of age.
26302971 Interleukin-18, interleukin-12B and interferon-γ gene polymorphisms in Brazilian patients 2015 Oct Polymorphisms in interleukin (IL)-18, IL-12 and interferon (IFN)-γ genes are associated with different levels of cytokines expression and have been associated with rheumatoid arthritis (RA). IL-18 +105 A/C, IL-12B +1188 A/C and IFN-γ +874 T/A polymorphisms were analyzed by restriction fragment length polymorphism-polymerase chain reaction (PCR) and amplification refractory mutation system PCR from 90 RA patients and 186 healthy individuals. There were significant differences to IL-18 +105 A/C polymorphism between the RA and control groups (odds ratio = 3.77; P < 0.0001). Individual carriers of the variant allele C had a 3.77-fold increased risk of for RA (P = 0.0032). No association was observed for IL-12B and IFN-γ polymorphisms. Our finds suggest a possible role for IL-18 polymorphism in the RA susceptibility in studied population.
25927832 Heterogeneity of synovial molecular patterns in patients with arthritis. 2015 OBJECTIVES: Early diagnosis of rheumatoid arthritis (RA) is an unmet medical need in the field of rheumatology. Previously, we performed high-density transcriptomic studies on synovial biopsies from patients with arthritis, and found that synovial gene expression profiles were significantly different according to the underlying disorder. Here, we wanted to further explore the consistency of the gene expression signals in synovial biopsies of patients with arthritis, using low-density platforms. METHODS: Low-density assays (cDNA microarray and microfluidics qPCR) were designed, based on the results of the high-density microarray data. Knee synovial biopsies were obtained from patients with RA, spondyloarthropathies (SA) or osteoarthritis (OA) (n = 39), and also from patients with initial undifferentiated arthritis (UA) (n = 49). RESULTS: According to high-density microarray data, several molecular pathways are differentially expressed in patients with RA, SA and OA: T and B cell activation, chromatin remodelling, RAS GTPase activation and extracellular matrix regulation. Strikingly, disease activity (DAS28-CRP) has a significant influence on gene expression patterns in RA samples. Using the low-density assays, samples from patients with OA are easily discriminated from RA and SA samples. However, overlapping molecular patterns are found, in particular between RA and SA biopsies. Therefore, prediction of the clinical diagnosis based on gene expression data results in a diagnostic accuracy of 56.8%, which is increased up to 98.6% by the addition of specific clinical symptoms in the prediction algorithm. Similar observations are made in initial UA samples, in which overlapping molecular patterns also impact the accuracy of the diagnostic algorithm. When clinical symptoms are added, the diagnostic accuracy is strongly improved. CONCLUSIONS: Gene expression signatures are overall different in patients with OA, RA and SA, but overlapping molecular signatures are found in patients with these conditions. Therefore, an accurate diagnosis in patients with UA requires a combination of gene expression and clinical data.
26467057 Tinospora cordifolia inhibits autoimmune arthritis by regulating key immune mediators of i 2015 Dec Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation of the joints leading to tissue damage. Despite the availability of potent drugs including the biologics, many patients fail to respond to them, whereas others suffer adverse effects following long-term use of these drugs. Accordingly, the use of natural herbal products by RA patients has been increasing over the years. However, limited information about the mechanism of action of these natural products is a major shortcoming that prevents the widespread acceptance of herbal therapy by professionals and patients alike. In this study, we demonstrated the anti-arthritic activity of Tinospora cordifolia extract (TCE) using the rat adjuvant-induced arthritis model of human RA and elaborated the immune mechanisms underlying this effect. TCE treatment suppressed arthritic inflammation and bone and cartilage damage. The anti-inflammatory effect of TCE was mediated via reduction of the pro-inflammatory cytokines such as: IL-1β, TNF-α, IL-6, and IL-17; the frequency of IL-17-producing T cells; and the production of chemokines such as RANTES. Furthermore, TCE treatment limited bone damage by shifting the balance of mediators of bone remodeling (e.g., receptor activator of nuclear factor-kB ligand [RANKL] and MMP-9) in favor of anti-osteoclastic activity. Our results suggest that TCE and its bioactive components should be evaluated for their utility as therapeutic adjuncts to conventional drugs against RA.
26464634 Correlation between miR-126 expression and DNA hypomethylation of CD4+ T cells in rheumato 2015 It has been known that the occurrence of rheumatoid arthritis (RA) was closely correlated with DNA hypomethylation in CD4+ T cells, in which DNA methyltransferase plays a certain role. This study therefore investigated the effect of miR-126 on CD4+ T cell subgroup in RA patients and the alternation of DNA hypomethylation, in an attempt to provide new sights into the pathogenesis and treatment of RA. CD4+ T cells separated from RA patients were transfected with miRNA (miR)-126 expression vector or miR-126 inhibitor expression vector. The expression levels of CD11a, CD70 and DNMT1 mRNA were examined by real-time PCR. Protein levels of CD11a and CD70 were tested by flow cytometry while DNMT1 protein level was quantified by Western blotting. DNA was modified by sodium bisulfite and was sequenced for the methylation status of promoters of CD11a and CD70 genes. Both mRNA and protein expressions of CD11a and CD70 genes in CD4+ T cells were elevated by miR-126 transfection, along with decreased DNMT1 protein level but not mRNA level. The methylation degree of promoters of both CD11a and CD70 genes were significantly depressed after miR-126 transfection. The transfection by miR-126 inhibitor effectively reversed such effects. In RA patients, elevated miR-126 may promote the expression of CD11a and CD70 via the induction of hypomethylation of gene promoters by depressing DNMTI1 protein levels.
25962747 The Effects of Aerobic and Resistance Exercise on Markers of Large Joint Health in Stable 2015 Dec OBJECTIVE: Exercise is beneficial for people with rheumatoid arthritis (RA). However, patients and health professionals have expressed concern about the possible detrimental effects of exercise on joint health. The present study investigated the acute and chronic effects of high-intensity, low-impact aerobic and resistance exercise on markers of large joint health in RA. METHODS: Eight RA patients and eight healthy, matched control (CTL) participants performed 30 minutes' high-intensity, low-impact aerobic and lower-body resistance exercise, one week apart. Primary outcome measures assessing joint health were serum cartilage oligomeric matrix protein (sCOMP) and knee joint synovial inflammation (Doppler ultrasound colour fraction; CF). These measures were taken at baseline, immediately after and 0.5, one, two, six and 24 hours post-exercise. In a separate study, nine RA patients completed eight weeks of progressive exercise training. The same outcome measures were reassessed at baseline, and at one hour post-exercise of training weeks 0, 1, 4 and 8. RESULTS: RA patients showed higher overall sCOMP [RA: 1,347 ± 421, CTL: 1,189 ± 562 ng/mL; p < 0.05; effect size (ES) = 0.32] and CF when scanned longitudinally (RA: 0.489 ± 0.30 × 10(-3) , CTL: 0.101 ± 0.13 × 10(-3) ; p < 0.01; ES = 1.73) and transversely (RA: 0.938 ± 0.69 × 10(-3) , CTL: 0.199 ± 0.36 × 10(-3) ; p < 0.01; ES = 1.33) than CTL. However, no acute effects on joint health were observed post-exercise. Similarly, no chronic effects were observed over eight weeks of combined aerobic and resistance training in RA, with positive effects on physical fitness and function. CONCLUSIONS: RA patients on stable treatment with low disease activity were able to perform an individually prescribed high-intensity, low-impact aerobic and resistance exercise without changes in markers of large joint health.

26025136 Variations in patient-reported physical health between cardiac and musculoskeletal disease 2015 May 30 Population-based assessments of physical health are important to evaluate healthcare resource allocation. Normative data on the level of physical impairments attributable to specific diseases and severity levels within these diseases is critical to interpreting such data. Our objective, by means of a systematic review and meta-analysis, was to test the hypothesis that specific diseases which form cardiovascular and musculoskeletal disease spectra are associated with gradients of physical impairments. We examined a cardiovascular disease spectrum which consisted of hypertension, ischaemic heart disease and heart failure, and a musculoskeletal disease spectrum of lower back pain, osteoarthritis and rheumatoid arthritis. Using Medline, EMBASE and CINAHL databases, articles which had examined these morbidities and used either the SF-12 or SF-36 in general or primary care populations were selected; data was extracted independently by three reviewers. Study characteristics were described and the mean physical component summary scores of the SF-12 or SF-36 was analysed by disease, using random-effects meta-analysis. The association between disease and physical health (mean physical component summary scores) was assessed using multilevel meta-regression analysis, adjusting for age, health setting, country, disease definition and SF-12 or 36 format. From this search, 26 articles were identified, yielding 70 separate estimates of mean physical component summary scores across the morbidities from 14 different countries. For the selected conditions, pooled unadjusted mean physical component summary scores were: 44.4 for hypertension, 38.9 for ischaemic heart disease, 35.9 for heart failure, 39.5 for lower back pain, 36.0 for osteoarthritis and 36.5 for rheumatoid arthritis. The adjusted meta-regression showed mean physical component summary score difference for ischaemic heart disease of -4.6 (95 % confidence interval -6.0 to -3.2) and heart failure -7.5 (-9.1 to -5.9) compared to the hypertension category. For osteoarthritis -4.2 (-5.3 to -3.0) and rheumatoid arthritis -3.9 (-9.5 to 1.6) compared to the lower back pain category. Our findings provide the benchmark norms for the differences in physical health within and between disease spectra. Improved characterisation of the relative impact of individual conditions on physical health will facilitate public health assessments of chronic diseases as well as assessments of interventions using functional patient-reported outcomes.
26591556 [Pleiotropic effects of atorvastatin in rheumatoid arthritis patients with no history of c 2015 AIM: To evaluate the effect of atorvastatin (liprimar) on the laboratory values of inflammation and blood lipid composition in rheumatoid arthritis (RA) patients with no history of cardiovascular diseases (CVD). Subjects and methods. Fifty women with grade II RA activity according to DAS28 and radiologic (erosive) Stages I-III were examined; the patients were not former or current smokers; all were seropositive; their mean age was 50.2±9.9 years. All the patients with RA were divided into 2 groups: Group 1 took no atorvastatin and continued to receive standard previously prescribed therapy; Group 2 used atorvastatin in a dose of 20 mg. Lipidogram readings and the levels of Apo-A and Apo-B, neopterin, tumor necrosis factor-α, C-reactive protein, sP-selectin, sE-selectin, interleukin (IL)-6, IL-10, IL-12, and matrix metalloproteinases 3 and 9 were assessed. RESULTS: The patients with RA show obvious blood lipid composition impairments. Incorporation of atorvastatin (liprimar) into combination therapy for RA not only causes a considerable reduction in total cholesterol, low-density lipoprotein cholesterol, triglycerides, and apo-B levels, but also positively affects the inflammatory activity of the disease, by lowering the level of proinflammatory cytokines and increasing that of the anti-inflammatory cytokine IL-10. CONCLUSION: The above changes may underlie the prevention of CVD complications in patients with RA.
27989589 Efficacy of triple association methotrexate, sulfasalazine and hydroxychloroquine in early 2017 Oct OBJECTIVES: To evaluate the efficacy of the triple synthetic Disease Modifying Anti-Rheumatic Drugs (sDMARD) combination methotrexate, sulfasalazine and hydroxychloroquine versus a biologic DMARD (bDMARD) in the treatment of early rheumatoid arthritis. METHODS: A systematic literature search was performed using the PubMed and Cochrane databases, and abstracts presented at rheumatology scientific meetings until December 2013. Randomized controlled trials comparing the efficacy and the safety of biologic DMARD with the triple combination were included. Outcome measures were Van der Heijde modified Sharp score (SHS), remission rate, ACR criteria response, adverse events. RESULTS: A total of 1225 abstracts were screened. We extracted data from 5 trials including patients (515 in the triple combination group and 710 in the bDMARD group). We showed higher ACR70 response (OR=1.79, 95% CI [1.17, 2.72]) in patients treated with bDMARDs, whereas radiological progression was not different from patient with triple combination (OR=1.10, 95% CI [-0.04, 0.28]). At year 2, ACR70 response and remission rate, the results were similar in both groups with respectively OR=1.44 (95% CI [0.86, 2.43]) and SMD=0.45 (95% CI [0.17, 0.72]). The proportion of serious adverse events was similar in both groups OR=1.02 (95% CI [0.68, 1.52], P=0.92, I(2)=0%). Gastro-intestinal adverse events were higher in the triple combination group (OR=1.75, 95% CI [0.73, 4.21], P=0.21, I(2)=75%). Infectious adverse events were more frequent in the bDMARD group (OR=0.50, 95% CI [0.35, 0.70], P<0.0001, I(2)=36%). CONCLUSION: Biological treatment seems to be more efficient than triple combination in terms of radiological progression in RA with inadequate response to methotrexate.
26697765 Treating to target in established rheumatoid arthritis: Challenges and opportunities in an 2015 Aug There is increasing consensus that periodic monitoring of disease activity status in rheumatoid arthritis (RA) patients to achieve and maintain remission, or at least low disease activity (LDA), the so-called treat to target (T2T) improves outcomes regardless of the duration of disease. Based on systematic literature reviews (SLRs) of clinical trials and registries, International Recommendations published in 2015 represent expert opinion describing efficacy and safety of conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and biologic DMARDs (bDMARDs). A total of 10 recommendations are detailed from four "Overarching Principles": (1) treatment decisions are shared between patient and rheumatologist; (2) the primary goalv is to maximize long-term quality of life by controlling the symptoms, preventing joint damage, and by normalizing the function and social and work participation; (3) abrogation (not just control) of inflammation is the most effective method to achieve this goal; (4) T2T by measuring disease activity regularly and adjusting therapy to achieve remission/LDA optimizes outcomes in RA. The SLRs provide solid evidence that methotrexate is the "anchor" of csDMARD and that step-up therapy by adding/substituting other csDMARDs, such as sulfasalazine (SSZ), hydroxychloroquine (HCQ), or/and leflunomide (LEF) is as effective as combination therapy to initiate. Tofacitinib, a recently marketed csDMARD, may be more effective in comparison to MTX, and can be used in combination. Rapid disease control can be achieved by "bridging" with various regimens of glucocorticoids (GCs), but tapering to doses ≤7.5 mg/day is critical to limit side effects. In practice settings, use of bDMARDs is influenced by reimbursement. Tumor necrosis factor inhibitors (TNFi) are highly used, but as more data emerge, there appear to be no major differences to more recently available targeted bDMARD monoclonal antibodies such as abatacept (co-stimulation blockade), rituximab (B cell depleting), tocilizumab (TCZ) (interleukin (IL)-6 receptor blockade). Rituximab appears to be most effective for seropositive patients, and tocilizumab may be more effective as a monotherapy in patients intolerant to csDMARDs. Besides T2T, attention to managing treatment and optimizing outcomes should take into account potential adverse effects, such as risk of serious infection, as well as potential morbidity/mortality related to cardiovascular events, pulmonary disease, osteoporosis, diabetes, and fibromyalgia which often influence some measures, such as the Health Assessment Questionnaire (HAQ).
26521731 Arthritic and non-arthritic synovial fluids modulate IL10 and IL1RA gene expression in dif 2015 Nov OBJECTIVE: Synovitis with an increased presence of macrophages is observed in osteoarthritis (OA) and rheumatoid arthritis (RA). Given the important role of macrophages in arthritis, we investigated the influence of OA and RA synovial fluid (SF) on primary human monocytes (Mo), their lineage precursors. METHOD: Adherent monocytes without any stimulation (Mo(-)) or stimulated with IFN-γ and TNF-α (Mo(IFN-γ/TNF-α)) or IL-4 (Mo(IL-4)) were exposed to SF from 6 donors without any known joint disease (SF-Ctrl), 10 OA donors (SF-OA), and 10 RA donors (SF-RA). The transcriptional expression of IL6, IL1B, TNFA, IL10, CCL18, CD206, and IL1RA was analyzed. RESULTS: Mo(-) exposed to SF-RA had a lower expression of IL10 and a higher expression of IL1RA than when exposed to SF-Ctrl. Mo(IL-4) exposed to SF-RA had a lower expression of IL10 and CCL18 than when exposed to SF-Ctrl and Mo(IFN-γ/TNF-α) were not affected by SF-RA. Mo exposed to SF-OA also expressed less IL10, but only upon stimulation with IL-4, and expressed more IL1RA than when exposed to SF-Ctrl in any condition. CONCLUSION: A lower expression of IL10 may be regarded as a response to less inflammatory conditions since IL10 expression is higher in response to IFN-γ/TNF-α stimulation, probably as a feedback mechanism. Therefore, the lower expression of IL10 and the higher expression of IL1RA in Mo exposed to arthritic than to non-arthritic SF suggest that arthritic SF is mainly reducing the inflammatory responses in Mo. This may mimic the response of monocytes/macrophages recruited to the joint, where feedback mechanisms counteract pro-inflammatory processes.
27181231 [Autoimmune disease and epigenome regulation]. 2016 Epigenetic modifications play a central role in the cellular programming of gene expression. Two of the most characterized epigenetic modifications are DNA methylation and histone modification. Recent observation that a number of GWAS SNP for immunological diseases localize to immune enhancers suggests the importance of epigenetic modifications that control enhancer activity. Epigenome-wide analysis of DNA-methylation in systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) revealed differential DNA methylation in a number of disease-related gene pathways. With regard to histone mark, the requirement of millions of cells for established protocol prevents application to clinical samples. However, recent technical advances enable us to capture open chromatin in small amount of patient samples. As epigenetic modifications function as an integrator of environmental stimulation and the underlying genetic variant, detailed epigenetic analysis combined with genetic and environmental factors may facilitate the understanding of the progression of human immunological diseases.
26283657 Plasma n-3 fatty acids and clinical outcomes in recent-onset rheumatoid arthritis. 2015 Sep 28 A randomised controlled trial (RCT) of high-dose v. low-dose fish oil in recent-onset rheumatoid arthritis (RA) demonstrated that the group allocated to high-dose fish oil had increased remission and decreased failure of disease-modifying anti-rheumatic drug (DMARD) therapy. This study examines the relationships between plasma phospholipid levels of the n-3 fatty acids in fish oil, EPA and DHA, and remission and DMARD use in recent-onset RA. EPA and DHA were measured in blood samples from both groups of the RCT. The data were analysed as a single cohort, and Cox proportional hazards models were used to examine relationships between plasma phospholipid (PL) EPA and DHA and various outcome measures. When analysed as a single cohort, plasma PL EPA was related to time to remission, with a one unit increase in EPA (1% total fatty acids) associated with a 12% increase in the probability of remission at any time during the study period (hazard ratio (HR)=1.12; 95% CI 1.02, 1.23; P=0.02). Adjustment for smoking, anti-cyclic citrullinated peptide antibodies and 'shared epitope' HLA-DR allele status did not change the HR. Plasma PL EPA, adjusted for the same variables, was negatively related to time to DMARD failure (HR=0.85; 95% CI 0.72, 0.99; P=0.047). The HR for DHA and time to remission or DMARD failure were similar in magnitude to those for EPA, but not statistically significant. Biomarkers of n-3 status, such as plasma PL EPA, have the potential to predict clinical outcomes relevant to standard drug treatment of RA patients.
