Abstract
Rheumatoid arthritis (RA) is polygenic autoimmune disease with unclear etiology. MicroRNAs (miRNAs) play a critical role in the pathogenesis of RA. The objective of this study was to evaluate the role of miR-146a in patients with RA receiving Tripterygium wilfordii Hook F (TwHF) treatment.In total, 69 patients with RA and 69 healthy controls (HC) were included in the study, and patients with RA received TwHF treatment for 24 weeks. Blood samples were collected from RA patients and HC, and peripheral blood mononuclear cells (PBMCs) were isolated. Expression of miR-146a was analyzed in RA patients (baseline, 12 weeks and 24 weeks) and HC.Circulating miR-146a expression was markedly increased in patients with RA compared with healthy controls (P < .001), ROC analysis of miR-146a for diagnosis for RA showed that the AUC was 0.908 (95% CI: 0.862-0.955) with a sensitivity of 87.0% and a specificity of 82.6% at best cutoff. And miR-146a expression was positively associated with the DAS28 score and CRP level (P = .002 and P = .019). Moreover, miR-146a expression was markedly reduced after TwHF therapy (P < .001), and baseline miR-146a level was observed to present an increased tendency in responders compared with non-responders at 24 weeks (P = .066).Our study presented that circulating miR-146a level was correlated with risk and disease activity of RA patients by TwHF treatment, which could strikingly decrease expression of miR-146a in RA patients, and miR-146a may have a value in predicting clinical response of TwHF treatment. It indicates that circulating miR-146a plays a prominent role in RA patients treated by TwHF.

Abstract
BACKGROUND Rheumatoid Arthritis (RA) is associated with an increased risk of cardiovascular disease (CVD). The physical dysfunction symptomatic of RA means people living with this disease spend large periods of the day sedentary, which may further elevate their risk of CVD. The primary aim of this study was to investigate relationships between objectively assessed sedentary behaviour patterns and light physical activity (LPA) with 10-year risk of CVD. Secondary aims were to explore the role of sedentary behaviour patterns and LPA for individual CVD risk factors and functional disability in RA. The extent to which associations were independent of moderate-to-vigorous physical activity (MVPA) engagement was also examined. METHODS Baseline data from a subsample of participants recruited to the Physical Activity in Rheumatoid Arthritis (PARA) study were used to answer current research questions. Sixty-one patients with RA (mean age (± SD) = 54.92 ± 12.39 years) provided a fasted blood sample and underwent physical assessments to evaluate factors associated with their cardiovascular health. Sedentary behaviour patterns (sedentary time, sedentary bouts, sedentary breaks), LPA and MVPA were measured via 7-days of accelerometry. Ten-year CVD risk was computed (Q-risk-score2), and functional disability determined via questionnaire. RESULTS Regressions revealed significant positive associations between sedentary time and the number of sedentary bouts per day ≥20 min with 10-year CVD risk, with the reverse true for LPA participation. Associations were independent of MVPA engagement. CONCLUSIONS Promoting LPA participation and restricting sedentary bouts to <20 min may attenuate long-term CVD risk in RA, independent of MVPA engagement.

Abstract
Purpose To evaluate the effectiveness of a workplace integrated care intervention on at-work productivity loss in workers with rheumatoid arthritis (RA) compared to usual care. Methods In this randomized controlled trial, 150 workers with RA were randomized into either the intervention or control group. The intervention group received an integrated care and participatory workplace intervention. Outcome measures were the Work Limitations Questionnaire, Work Instability Scale for RA, pain, fatigue and quality of life (RAND 36). Participants filled out a questionnaire at baseline, and after 6 and 12 months. We performed linear mixed models to analyse the outcomes. Results Participants were on average 50 years of age, and mostly female. After 12 months, no significant intervention effect was found on at-work productivity loss. We also found no significant intervention effects on any of the secondary outcomes. Conclusions We did not find evidence for the effectiveness of our workplace integrated care intervention after 12 months of follow up. Future studies should focus on investigating the intervention in groups of workers with severe limitations in work functioning, and an unstable work situation.

Clin Rheumatol 2017; 36:499-506. [PMID: 27832385 PMCID: PMC5323479 DOI: 10.1007/s10067-016-3470-z] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2016] [Revised: 10/28/2016] [Accepted: 10/30/2016] [Indexed: 01/14/2023]
Abstract
The aim of the present study was to calculate non-medical costs during year 1 after diagnosis in two cohorts of patients with early rheumatoid arthritis enrolled 1996-1998 and 2006-2009. Clinical data were collected regularly in both cohorts. Besides information about healthcare utilization and days lost from work, patients reported non-medical costs for aids/devices, transportation, formal and informal care. Formal care was valued as full labour cost for official home help (€42.80/h) and informal care from relatives and friends as opportunity cost of leisure time, corresponding to 35% of labour cost (€15/h). In both cohorts, only 2% used formal care, while more than 50% used informal care. Prescription of aids/devices was more frequent in cohort 2 and more women than men needed aids/devices. Help with transportation was also more common in cohort 2. Women in both cohorts needed more informal care than men, especially with personal care and household issues. Adjusting for covariates in regression models, female sex remained associated with higher costs in both cohorts. Non-medical costs in cohort 2 were €1892, €1575 constituting informal care, corresponding to 83% of non-medical costs. Total non-medical costs constituted 25% of total direct costs and 11% of total direct and indirect costs. Informal care accounted for the largest part of non-medical costs and women had higher costs than men. Despite established social welfare system, it is obvious that family and friends, to a large extent, are involved in informal care of patients with early RA, and this may underestimate the total burden of the disease.

Abstract
BACKGROUND Use of biologic drugs is approved for treatment in rheumatoid arthritis (RA), both in established disease and at the early stage of RA (ERA). Identification of ERA and an early therapeutic strategy would lead to greater clinical improvement. Only a few indirect comparisons of the efficacy of different biologic agents in established RA have been performed and, to date, no studies reporting direct comparisons have been performed in ERA. OBJECTIVE The aim of this study was to compare, by use of a mixed treatment comparison (MTC), the efficacy profiles of biologic agents in ERA. METHODS An extensive literature search was performed to identify results of randomized, controlled trials (RCTs) evaluating biologic agents at licensed doses to treat patients affected by ERA. The primary end points for the analysis were the American College of Rheumatology 20% improvement (ACR20), ACR50, and ACR70 responses from baseline to various times of follow-up. WinBUGS 1.4 software (MRC Biostatistics Unit, Cambridge, UK) was used to perform the analyses. The MTC results are reported as the relative risk of a response for every single treatment coadministered with methotrexate, versus methotrexate plus placebo, which was used as a comparator in all RCTs. RESULTS Ten scientific papers met the study inclusion criteria and were included in the analysis. Data on the use of infliximab, adalimumab, etanercept, abatacept, golimumab, and rituximab were included. No studies reported on the use of certolizumab pegol or tocilizumab in ERA. All biologic agents coadministered with methotrexate proved to be more efficacious than methotrexate plus placebo in inducing ACR20, ACR50, and ACR70 responses. The biologic agent characterized by the highest probability of inducing an ACR70 response was adalimumab (33.28%). Etanercept was the biologic agent with the highest probability of inducing ACR20 and ACR50 responses, in comparison with all other biologic agents, with probability rates of 62.95 and 37.1%, respectively. CONCLUSION In our analysis, adalimumab proved to be the biologic agent with the highest probability of inducing an ACR70 response in patients affected by ERA, while etanercept was the biologic agent with the highest probability of inducing ACR50 and ACR20 responses.

Abstract
To examine the effect of koumine, a Gelsemium alkaloid, on two experimental models of rheumatoid arthritis (RA), rats with adjuvant-induced arthritis (AIA) and collagen-induced arthritis (CIA) were administered koumine (0.6, 3, or 15 mg/kg/day) or vehicle through gastric gavage (i.g.). Clinical evaluation was performed via measurements of hind paw volume, arthritis index (AI) score, mechanical withdrawal threshold, organ weight, and by radiographic and histological examinations. Levels of interleukin (IL)-1β, tumor necrosis factor (TNF)-α, and antitype II collagen (CII) antibody were also examined. In rats with AIA, koumine reduced the AI score and mechanical allodynia of the injected hind paw in a dose-dependent manner and significantly inhibited increase in thymus and liver weights. In rats with CIA, koumine inhibited increase in hind paw volume, AI score, and mechanical allodynia in a dose-dependent manner and reduced joint space narrowing. Furthermore, koumine also attenuated the increase in the expression of IL-1β and TNF-α, as well as the robust increase of serum anti-CII antibodies in response to immunization. These results suggested that koumine effectively attenuated arthritis progression in two rat models of RA and that this therapeutic effect may be associated with its immunoregulatory action.

Abstract
The present study aimed to investigate the effect of co‑culture of fibroblast‑like synoviocytes (FLS) with human umbilical cord‑mesenchymal stem cells (UC‑MSCs) on rheumatoid arthritis (RA) and to understand the mechanisms that mediate the induced changes. FLS and UC‑MSCs were isolated and cultured individually, FLS were then cultured with or without UC‑MSCs. The phenotype of UC‑MSCs was analyzed prior to co‑culture. The UC‑MSCs were successfully isolated and expanded, and exhibited a fibroblast‑like morphology. Enzyme‑linked immunosorbent assay (ELISA) and reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) were performed to determine the expression levels of interleukin (IL)‑1β, IL‑6, and chemokine (C‑C motif) ligand (CCL)‑2. The cell apoptosis rate was determined by flow cytometry. Furthermore, the RNAs of aggrecan and collagen type II were isolated and assessed in a chondrogenesis assay following co‑culture for 7, 14, 21 and 28 days. Protein expression levels of apoptosis‑related proteins, including B‑cell lymphoma (Bcl‑2), Bcl‑2‑associated X protein, p53 and phospho (p)‑AKT, and growth differentiation factor‑5 were analyzed by western blotting. ELISA and qRT‑PCR demonstrated that compared with FLS cultured alone, co‑culture with UC‑MSCs significantly downregulates the expression levels of IL‑1β, IL‑6 and CCL‑2. Additionally, the percentage of apoptotic cells was significantly increased in the co‑cultured cells (P<0.05), and the relative RNAs levels of aggrecan and collagen type II were increased compared with FLS alone. Furthermore, the expression levels of Bcl‑2 (P<0.05) and p‑AKT (P<0.05) were significantly decreased, whereas, p53 (P=0.001), Bax (P<0.01) and GDF‑5 (P<0.01) were increased by co‑culture of FLS with UC‑MSCs compared with FLS alone. In conclusion, co‑culture of FLS with UC‑MSCs may be important and clinically useful for the treatment of RA by inhibiting the expression of pro‑inflammatory mediators, inducing apoptosis and promoting chondrogenesis.

Abstract
Osteoarthritis (OA) and rheumatoid arthritis (RA) are chronic disorders associated with inflammation of joints characterized by damage to the underlying cartilage and bone. Bone marrow mesenchymal stem cells (BMSCs) are candidates for regeneration of bone and cartilage, which is inhibited by inflammatory cytokines in OA and RA, in particular tumor necrosis factor-α (TNF-α). This study aimed to investigate if the c-Jun N-terminal kinases (JNK)-specific inhibitor SP600125 could enhance the anti-apoptosis and migration of BMSCs treated with TNF-α. The level of apoptosis was evaluated via terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL)/4',6-diamidino-2-phenylindole (DAPI) staining, annexin V/propidium iodide (PI) staining and western blotting. Migration of BMSCs was assessed using transwell migration chambers. We showed that the survival capacity and migration of BMSCs was significantly inhibited by TNF-α, which was blocked by pretreatment with SP600125. In the presence of SP600125, expression of cleaved caspase-9/-3 and p53 as well as the ratio of Bax to Bcl-2 was significantly decreased compared to treatment with TNF-α alone. Our results therefore indicate that SP600125 improves the migration capacity of TNF-α-treated BMSCs and exerts a significant effect on the viability of TNF-α-treated BMSCs through reducing the up-regulation of p53, caspase-9/-3 and the Bcl-2 family induced by TNF-α. These findings suggest that SP600125 is of potential use in promoting the regeneration of bone and cartilage in OA and RA.

Abstract
Methotrexate (MTX), the most commonly used anti-rheumatic drug against RA, enters the cell via the action of the reduced folate carrier 1(RFC1). A major polymorphism of the RFC1 gene, 80G/A, has been reported to influence the activity of RFC1, resulting in variable intracellular MTX-polyglutamate (MTX-PG) levels. However, the association studies addressing the RFC1 80G/A polymorphism and MTX efficacy or toxicity in Rheumatoid arthritis (RA) has yielded conflicting results. In the present meta-analysis, we aimed to evaluate the association between the RFC1 80G/A polymorphism and MTX efficacy or toxicity in RA patients. A total 17 studies met our inclusion criteria. Among them, 12 studies with 2049 subjects reported the association between the RFC1 80G/A and MTX response, and 12 studies involving 2627 subjects were on MTX-related toxicity. Meta-analysis revealed significant association between RFC1 80G/A polymorphism and MTX efficacy (odds ratio (OR) for the A allele=1.29, 95% confidence interval (CI) 1.05-1.67, P=0.02; for AA genotype: OR=1.49, 95%CI 1.17-1.907, P=0.001). However, no association could be detected in the analysis of MTX-related toxicity. Stratification by ethnic population also indicated an association between this polymorphism and MTX efficacy in Asian group (P=0.002 for A allele; P=0.003 for AA genotype), but not in the Caucasian group (P=0.15 for A allele; P=0.05 for AA genotype). In both Asian and Caucasian sub-groups, no influence of the RFC1 80G/A polymorphism on MTX toxicity can be detected. In conclusion, the RFC1 G80A polymorphism is associated with responsiveness to MTX therapy, but may not be associated with MTX toxicity in RA patients.

Abstract
Introduction Rheumatoid arthritis (RA) is a chronic, inflammatory, and systemic disease with symptoms that limit activities and affect quality of life. RA is associated with an increased risk of developing comorbidities, some of which are also known to be associated with lifestyle habits such as physical activity, diet, smoking, and alcohol. There has been an augmented focus on the implementation and maintenance of healthy lifestyle habits even for patients with RA in the past decade, but little is known about the link between patients’ experiences of lifestyle habits and quality of life. The aim of the study was thus to describe and explore how patients with established RA experience the influence of lifestyle habits on quality of life. Methods The study had a descriptive and explorative design, based on qualitative content analysis. Strategic sampling was used in order to achieve variations in experiences. Twenty-two patients with RA (14 women and 8 men) from 30 to 84 years old, with a disease duration ranging from 8 to 23 years, were interviewed. Results The analysis of the influence of lifestyle habits on quality of life resulted in the theme balancing between ideality and reality. Three categories emerged about how lifestyle habits influenced quality of life by limitations (including insufficiency and adaptation), self-regulation (including guilt and motivation), and companionship (including belonging and pleasure). Conclusions Quality of life for patients with established RA was influenced by the balance between ideality and reality in the lifestyle habits: physical activity, diet, smoking, and alcohol. This is important new knowledge for health professionals when discussing lifestyle habits with RA patients.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by inflammation and destruction of the joints. OBJECTIVES This research aims to estimate the economic burden of RA in Taiwan. METHODS The National Health Insurance Research Database (NHIRD), a claims-based dataset encompassing 99 % of Taiwan's population, was applied. We used a micro-costing approach for direct healthcare costs and indirect social costs by estimating the quantities and prices of cost categories. Direct costs included surgeries, hospitalizations, medical devices and materials, laboratory tests, and drugs. The costs and quantities of the direct economic burden were calculated based on 2011 data of NHIRD. We identified RA patients and a control cohort matched 1:4 on demographic and clinical covariates to calculate the incremental cost related to RA. Indirect costs were evaluated by missed work (absenteeism) and worker productivity (presenteeism). For the indirect burden, we estimated the rate of absenteeism and presenteeism from a patient survey. Costs were presented in US dollars (US$1 = 30 TWD). RESULTS A total of 41,269 RA patients were included in the database with incremental total direct cost of US$86,413,971 and indirect cost of US$138,492,987. This resulted in an average incremental direct cost of US$2050 per RA patient. Within direct costs, the largest burdens were associated with drugs (US$73,028,944), laboratory tests (US$6,132,395), and hospitalizations (US$3,208,559). For indirect costs, absenteeism costs and presenteeism costs were US$16,059,681 and US$114,291,687, respectively. CONCLUSIONS The economic burden of RA in Taiwan is driven by indirect healthcare costs, most notably presenteeism.

Abstract
OBJECTIVE To evaluate the efficacy and safety of secukinumab, a fully human antiinterleukin-17A monoclonal antibody, administered with an intravenous (IV) or subcutaneous (SC) loading regimen versus placebo, in patients with active rheumatoid arthritis (RA). METHODS In this phase II, double-blind, double-dummy, 52-week study (ClinicalTrials.gov NCT01359943), 221 patients with inadequate response to methotrexate were randomized (2:2:1) to secukinumab, IV loading 10 mg/kg at baseline, Weeks 2 and 4, then SC 150 mg every 4 weeks (n = 88); secukinumab SC loading 150 mg once weekly for 5 weeks, then every 4 weeks (n = 89); or a matching placebo (followed by secukinumab 150 mg every 4 weeks starting Week 16; n = 44). The primary endpoint was superior efficacy of pooled secukinumab versus placebo using American College of Rheumatology 20% response (ACR20) at Week 12. RESULTS The primary efficacy endpoint was not met: ACR20 response at Week 12 was 49.2% for pooled secukinumab versus 40.9% for placebo (p = 0.3559). These variables improved significantly with pooled secukinumab versus placebo at Week 12 (all p < 0.05): the 28-joint Disease Activity Score (DAS28), patient's and physician's global assessment of disease activity, patient's assessment of RA pain, and high-sensitivity C-reactive protein levels. Results of continuous efficacy outcomes were similar between the IV and SC loading regimens. The most frequent adverse events were infections, with similar rates across secukinumab and placebo. CONCLUSION Although the primary endpoint (ACR20) was not met, secukinumab demonstrated improved efficacy in reducing disease activity over placebo as measured by DAS28 and other secondary endpoints.

Comparison of the Belgian Rheumatoid Arthritis Disability Assessment and Health Assessment Questionnaires as Tools to Predict the Need for Support Measures in Patients with Rheumatoid Arthritis. PLoS One 2016; 11:e0146688.

Abstract
OBJECTIVE Scores on the Health Assessment Questionnaire (HAQ) predict the need for support measures in patients with rheumatoid arthritis (RA). In this study we compare the performance of the HAQ in this context with that of the more disease-specific Belgian Rheumatoid Arthritis Disability Assessment (BRADA) questionnaire. METHODS In this multicenter observational study, patients with RA and disease duration of at least one year who consulted their rheumatologist for a routine follow-up visit filled out the HAQ, and BRADA questionnaires. The performance of HAQ and BRADA to predict the need for support measures available to patients with RA was evaluated using Receiver Operator Characteristic (ROC) curves, with the expert opinion of the rheumatologist as a reference. RESULTS The study analyzed data of 301 patients with RA (70.8% females) with mean age 59.8 ± 12.8, disease duration 11.4 ± 9.3 years, and DAS28 values of 2.84 ± 1.18. HAQ scores averaged 0.97 ± 0.73 and BRADA scores were 3.92 ± 3.49 over the last week and 3.89 ± 3.50 over the last 3 months. The area under the ROC curves for the BRADA scores for the support measures investigated ranged from 0.702 to 0.862 and did not differ significantly from those of the HAQ (range 0.725-0.860). CONCLUSION The disease-specific BRADA questionnaire is equivalent to the HAQ in predicting the need for support measures in patients with stable RA.

Abstract
Adjuvant arthritis in rats, as rheumatoid arthritis in humans, may be of greater or lesser severity, namely polyarthritis and monoarthritis, respectively. The present study was planned to evaluate the oxidative changes in the blood and specifically in the serum albumin of rats with adjuvant-induced mono- and poly-arthritis. Total antioxidant capacity, thiols, carbonyl groups, albumin, uric acid and ascorbic acid were measured in the total serum. The specific oxidative status of albumin was also measured after separation by affinity chromatography. All serum oxidative parameters were close to normal in monoarthritic rats with the exception of the ascorbic acid concentration, which was 23 % lower, and albumin carbonyl groups, which were 64 % higher. Many modifications were found in polyarthritic rats, specially the ascorbic acid concentration (35 % lower) and albumin carbonyl groups (102 % higher). The results revealed that the levels of ascorbic acid in the serum and carbonyl groups in the albumin molecule can be regarded as indicators of the severity of arthritis since they were modified by both monoarthritis and polyarthritis, but to different degrees.

Abstract
OBJECTIVE To assess trends and predictors of mechanical devices/aids use by rheumatoid arthritis (RA) patients since the introduction of biologic disease-modifying antirheumatic drugs (DMARDs). METHODS Sociodemographic characteristics, disease characteristics, and mechanical aid use (assessed using the Health Assessment Questionnaire) were compared among RA patients ages >17 years at diagnosis, enrolled in the Consortium of Rheumatology Researchers of North America (CORRONA) registry during January 2001 to December 2003 and January 2010 to December 2012. Univariate and multivariate logistic regression analyses were used to identify predictors of mechanical aid use among patients in both cohorts. RESULTS Sociodemographic characteristics were similar between 1,096 patients in the 2001-2003 cohort and 11,140 patients in the 2010-2012 cohort. Disease activity was significantly lower among patients in the 2010-2012 cohort (mean ± SD Clinical Disease Activity Index score 10.1 ± 11.1 versus 17.0 ± 13.8; P < 0.001). A greater proportion of patients in the 2010-2012 cohort received biologic DMARDs (50.7% versus 32.5%; P < 0.001) and fewer were biologic-naive (39.1% versus 61.6%; P < 0.001). Fewer patients in the 2010-2012 cohort used any mechanical devices/aids (31.1% versus 40.8%; P < 0.001). In multivariate analysis, patients in the 2010-2012 cohort and those with a history of biologic agent use were less likely to use devices/aids (odds ratio [OR] 0.77 [95% confidence interval (95% CI) 0.66-0.90] and OR 0.68 [95% CI 0.62-0.75], respectively). Predictors of greater devices/aids usage included older age, female sex, higher disease activity, and less employment. Effect sizes were greatest for disease activity and employment. CONCLUSION Mechanical devices/aids use among patients with RA was significantly lower during 2010-2012 versus 2001-2003 and among biologic-experienced patients, suggesting reduced disability.

Abstract
Many publications with conflicting results have evaluated serum levels of copper (Cu) and zinc (Zn) in patients with rheumatoid arthritis (RA). To derive a more precise estimation of the relationship, a meta-analysis was conducted. Relevant published data were retrieved through PubMed, Chinese National Knowledge Infrastructure (CNKI), and Chinese Biomedical Database (CBM) before September 20, 2014. Weighted mean difference (WMD) with a 95 % confidence interval (95 % CI) was calculated using STATA 11.0. A total of 26 studies, including 1444 RA cases and 1241 healthy controls, were collected in this meta-analysis. Pooled analysis found that patients with RA had a higher serum level of Cu and a lower serum Zn level than the healthy controls (Cu (μg/dl), WMD = 31.824, 95 % CI = 20.334, 43.314; Zn (μg/dl), WMD = -12.683, 95 % CI = -19.783, -5.584). Subgroup analysis showed that ethnicity had influence on the serum level of Cu (μg/dl) (Caucasian, WMD = 43.907, 95 % CI = 35.090, 52.723, P < 0.001; Asian, WMD = 14.545, 95 % CI = -12.365, 41.455, P = 0.289) and Zn (μg/dl) (Caucasian, WMD = -11.038, 95 % CI = -23.420, 1.344, P = 0.081; Asian, WMD = -14.179, 95 % CI = -18.963, -9.394, P < 0.001) in RA and healthy controls. No evidence of publication bias was observed. This meta-analysis suggests that increased serum level of Cu and decreased serum level of Zn are generally present in RA patients.
