28395581 A case-control study of rheumatoid arthritis revealed abdominal obesity and environmental 2018 Mar BACKGROUND: The aim of this study was to evaluate new and previously hypothesized environmental risk factors and their interaction with rheumatoid arthritis (RA). METHODS: Four hundred patients recently diagnosed with RA and 400 controls frequency-matched by gender and birth year using Propensity Score Matching (PSM) were selected from northern China. Investigation was performed using self-reported data from interviewer-administered surveys. Associations between exposure variables and risk of RA were evaluated using multifactor non-conditional logistic regression. RESULTS: It showed that damp localities, draft indoor, abdominal obesity (AO), and family history of RA among first-degree relatives were independent risk factors and drinking of milk was independent protective factors for RA. Besides these risk factors, in women, infrequent delivery times, early age at menopause, and late age at menarche were also independent risk factors for RA. Both the additive model and the multiplication model suggested that there was an interaction relationship between AO and damp localities (p < .001), and only the additive model suggested that there was interaction relationship between AO and no milk drinking (p < .001) in our study population. In women, there was interaction relationship between AO and damp localities (p < .001) and between AO and age at menopause (p < .001). CONCLUSIONS: In northern China, damp localities, draft indoor, AO, family history of RA among first-degree relatives, and no milk drinking may be important risk factors of RA patients.
28572463 Cardiovascular Risk Factors and Disease Characteristics Are Consistently Associated with A 2017 Aug OBJECTIVE: Arterial properties influence cardiovascular disease (CVD) risk. We identified potential determinants of arterial function in patients with rheumatoid arthritis (RA). METHODS: Relationships of traditional cardiovascular risk factors and RA characteristics with arterial stiffness (pulse wave velocity), wave reflection (augmentation index, reflected wave pressure, and reflection magnitude), and pressure pulsatility (central systolic and pulse pressure, peripheral pulse pressure, pulse pressure amplification, and forward wave pressure) were identified in multivariable backward regression models among 177 patients without established CVD (118 white, 32 Asian, 22 black, 5 mixed ancestry). RESULTS: Recorded characteristics explained 37% (pulse wave velocity) to 71% (reflected wave pressure) of the variability in arterial function. These factors were particularly associated with wave reflection and pressure pulsatility: RA duration (p = 0.04), rheumatoid factor status (p = 0.01 to 0.03), leukocyte counts (p = 0.02 to 0.05), and total cholesterol (p < 0.01 to 0.03). Body mass index (p < 0.01 to 0.02) and insulin resistance (p < 0.01 to 0.01) were related to reduced wave reflection and peripheral pulse pressure. Exercise (p = 0.02) and alcohol consumption (p < 0.01) were associated with increased pulse pressure amplification and decreased peripheral pulse pressure, respectively. Tumor necrosis factor-α inhibition (p < 0.01) was related to reduced pulse wave velocity, and tetracycline use (p = 0.02) to decreased peripheral pulse pressure. CONCLUSION: Traditional cardiovascular risk factors and disease characteristics are consistently associated with vascular hemodynamic alterations in RA. The relative effect of arterial stiffness, wave reflection, and pressure pulsatility on CVD risk in RA needs further study.
29077694 Practical Approach to the Evaluation and Management of Rheumatoid Arthritis-Interstitial L 2017 Sep The prevalence of interstitial lung disease in patients with rheumatoid arthritis varies from 10 to 42%. Rheumatoid arthritis patients with interstitial lung disease have three times the risk of death compared with those without the disease. Prognosis seems to be related to the high-resolution computed tomography pattern. Usual interstitial pneumonia pattern, resembling idiopathic pulmonary fibrosis, carries a worse prognosis. Validated strategies to identify different phenotypes and assess the disease activity in rheumatoid arthritis interstitial lung disease are lacking. However, the utilization of high-resolution computed tomography, composed disease activity scores, and anti-citrullinated peptide antibodies titers can help to guide decisions in clinical practice. Mechanisms involved in lung disease may be different from those implicated in joint involvement. This could explain why in a significant proportion of cases, interstitial lung disease does not improve or even worsens with standard therapies used successfully to treat the joint component (e.g. anti- umor necrosis factor agents). In this scenario, a group of drugs that targets the adaptive immune response (e.g. rituximab or abatacept) seems to target more specifically the process that takes place in the lungs. Moreover, the recent emergence of anti-fibrotic drugs, which have already proven effective in idiopathic pulmonary fibrosis, may provide an alternative treatment strategy in rheumatoid arthritis-usual interstitial pneumonia. In this review, we propose a practical approach to the evaluation and therapy of rheumatoid arthritis interstitial lung disease. Validation of strategies directed to assess the activity of lung disease and identify the underlying mechanisms are needed. Clinical trials evaluating a therapeutic approach with specific targets based on the disease phenotype are warranted.
29157669 The combination of IL-6 and its soluble receptor is associated with the response of rheuma 2018 Jun BACKGROUND: IL-6 contributes significantly to the chronic inflammatory process of rheumatoid arthritis (RA). Tocilizumab, a humanized anti-human IL-6 receptor antibody that blocks the signaling originated by the IL-6/IL-6R complex, is an effective treatment. However, predictors of the response to tocilizumab are still required. We aimed to combine IL-6 and soluble IL-6R (sIL-6R) levels to identify groups of responses. METHODS: Heparinized blood and clinical data from 63 RA patients were collected before treatment and after 3 and 6 months. Two-step clustering (SPSS v.18) was used to establish the relationship between IL-6 and sIL-6R. Then, we compared European League Against Rheumatism (EULAR) response criteria with remission achievement in the groups of patients. RESULTS: Three statistical significant clusters of RA patients (i.e., g1, g2, and g3) were defined by serum concentrations of IL-6 and sIL-6R at baseline. All groups of RA patients had higher IL-6 and sIL-6R levels than healthy donors. The levels of IL-6 expressed as median (IQR) in g1 patients were 124(90-183)pg/ml, in g2 12.3(4.4-24)pg/ml, and in g3 60.1(30-146)pg/ml (p < 0.001). The levels of sIL-6R expressed as mean ± sd in g1 patients were 250.5 ± 72ng/ml, in g2 269.1 ± 125ng/ml, and in g3 732.7 ± 243ng/ml (p < 0.001). Disease activity score (DAS)28, C-reactive protein, and erythrocyte sedimentation rate were comparable in the three groups at baseline. Disease duration in g3 was the longest (median(IQR) years: g1 = 11(5-15), g2 = 12(8-20), and g3 23(16-26); p = 0.006), with years of disease evolution being correlated with sIL-6R levels (R = 0.417, p < 0.001). Simple and Clinical Disease Activity Index (SDAI and CDAI) decreased significantly in the three groups. However, EULAR response criteria and remission achievement at 6m was different in the three groups (p = 0.03 and 0.04, respectively). In all. 17 out of the 18 patients in g1 had a good or moderate response to tocilizumab. Conversely, the percentage of patients with no response to tocilizumab was higher in g3 than in g1 and g2. We also observed different changing patterns of IL-6 and sIL-6R levels among the three groups. CONCLUSIONS: RA patients could be easily stratified prior to therapeutic intervention with two molecules related to the pathway blocked by tocilizumab. G1 patients, who had the best response to tocilizumab, had the highest level of IL-6 and the lowest level of sIL-6R.
28649878 Safety and effectiveness of tacrolimus add-on therapy for rheumatoid arthritis patients wi 2018 Jan OBJECTIVES: Post-marketing surveillance (PMS) was conducted to assess the safety and effectiveness of tacrolimus (TAC) add-on therapy for patients with rheumatoid arthritis (RA) and an inadequate response to biological disease-modifying anti-rheumatic drugs (DMARDs). METHODS: Patients with RA from 180 medical sites across Japan were registered centrally with an electronic investigation system. The observational period was 24 weeks from the first day of TAC administration concomitantly with biological DMARDs. RESULTS: Safety and effectiveness populations included 624 and 566 patients, respectively. Patients were predominantly female (81.1%), with a mean age of 61.9 years. Overall, 125 adverse drug reactions (ADRs) occurred in 94 patients (15.1%), and 15 serious ADRs occurred in 11 patients (1.8%). These incidences were lower compared with previously reported incidences after TAC treatment in PMS, and all of the observed ADRs were already known. A statistically significant improvement was observed in the primary effectiveness variable of Simplified Disease Activity Index after TAC treatment; 62.7% of patients achieved remission or low disease activity at week 24. CONCLUSIONS: TAC is well tolerated and effective when used as an add-on to biological DMARDs in Japanese patients with RA who do not achieve an adequate response to biological DMARDs in a real-world clinical setting.
28610614 Drug safety analyses in a rheumatoid arthritis registry: application of different approach 2017 Jun 13 BACKGROUND: Patient registry data serves an increasing role in drug safety and comparative effectiveness research, but registry databases often do not contain confounder information measured at the same time that treatments begin. This study evaluated a set of approaches for estimating confounder values at treatment initiation using actual data from a rheumatoid arthritis (RA) registry to examine the risk of infection associated with different biologic DMARDs (bDMARDs). METHODS: We examined the risk of infection associated with starting a TNF inhibitor (TNFi) versus any of the other non-TNFi bDMARDs. Different confounder assessment approaches were tested. All approaches were tested in Cox proportional hazard regression models that used a propensity score (PS). The confounder of interest was the disease activity score (DAS28-CRP). The confounder assessment approaches utilized different temporal relationships between the DAS28-CRP measurement and the start of the treatments of interest. RESULTS: We included 219 subjects with RA with 269 initiations of either a TNFi or a different bDMARD or both. Among this group, 305 infections were reported and confirmed through chart review. The hazard ratio (HR) for the risk of infection associated with use of a non-TNFi bDMARD ranged from 1.17 to 3.03 using 13 different approaches; only the approach with the highest HR produced results significantly different than one, but this approach included the fewest subjects and infections. CONCLUSIONS: The relative risk of infection for TNFi and other non-TNFi bDMARDs was similar using various approaches regarding which DAS28-CRP score should be used as the baseline measure in adjusted analyses.
28471034 Ultrasonography-detected subclinical inflammation in patients with hand osteoarthritis and 2018 Mar OBJECTIVES: A recent review of ultrasound (US) studies in osteoarthritis (OA) showed very limited data about hand OA. Previous US studies in patients with OA described a degree of overlap between the US appearance of rheumatoid arthritis (RA) and OA joints. The present study aimed to assess the US features of subclinical inflammation in RA and hand OA, using the same US examination protocol. METHODS: A retrospective, cohort study compared patients with established RA (n = 224) and hand OA (n = 73), with respect to several demographic, clinical, laboratory and US parameters. We used a 22-hand joint US examination protocol (wrists, metacarpophalangeal and proximal interphalangeal joints bilaterally - Outcome Measures in Rheumatology Clinical Trials [OMERACT] scoring system) for all patients. RESULTS: Subclinical joint inflammation in the context of equivocal clinical examination was found in 9.6% of OA patients compared with 46.4% of RA patients (p = 0.0001), despite the fact that there was no significant difference between the degree of chronic joint swelling (synovial hypertrophy grades 2 and 3; p = 0.75 and p = 0.11, respectively). The presence of osteophytes was more common in patients with hand OA, as expected (p = 0.0001). CONCLUSIONS: Our study findings reflected differences between the incidence and characteristics of subclinical inflammation in patients with RA and OA, which could be helpful in patients with an equivocal clinical examination or history of both diseases. Almost one in 10 patients with hand OA had active synovitis, while almost one in two patients with RA had uncontrolled inflammation in at least one joint.
28976635 The role of nurse practitioners in delivering rheumatology care and services: Results of a 2017 Nov BACKGROUND AND PURPOSE: Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by inflammation, pain, joint stiffness, and progressive joint destruction. An increased demand for rheumatology healthcare professionals is anticipated in coming years; utilizing more nurse practitioners (NPs) in rheumatology may help meet this demand, and improve early detection and diagnosis of RA. METHODS: The American Association of Nurse Practitioners surveyed, via e-mail, members who were working in primary care settings to understand their educational and professional needs to help manage their patients with RA. Respondents were surveyed about their NP certifications, patient panel, information received from rheumatologists on shared patients, RA tools or resources that would be helpful, confidence in diagnosing and managing patients with RA, interest in learning about particular topics regarding RA medications, and preferences for exchanging educational information with their professional colleagues. CONCLUSIONS: The results from this survey indicate that the role of NPs in managing RA could be optimized by improved communication with treating rheumatologists, access to educational tools and resources, and further education and training in the management of RA. IMPLICATIONS FOR PRACTICE: NPs in primary care can fill a resource gap and provide access to health care for patients with RA.
28081614 Stress coping strategies, spirituality, social support and posttraumatic growth in a Polis 2017 Oct The aim of this study was to explore the level of posttraumatic growth (PTG) and its relationship to the level of stress coping strategies, spirituality and social support among rheumatoid arthritis (RA) patients (n = 250). The level of PTG was measured by the Polish adaptation of the Posttraumatic Growth Inventory. Stress coping strategies were evaluated by the Polish adaptation of the Mini-COPE Inventory. Spirituality was measured by the Self-Description Questionnaire. Social support was assessed with the Berlin Social Support Scales. Stress coping strategies (return to religion, acceptance), spirituality and social support (need for support) were significantly related to the level of PTG among participants. Despite evidence of a beneficial relationship between PTG and the course of RA, little empirical attention has been paid to the factors associated with PTG among this patient group. Given the substantial health-related benefits associated with PTG among RA patients, it is important to further explore the phenomena of PTG among RA patients.
28183330 Th17 and CD24(hi)CD27(+) regulatory B lymphocytes are biomarkers of response to biologics 2017 Feb 10 BACKGROUND: The aim was to describe the regulatory B and T cells (Breg and Treg) and T helper 17 (Th17) lymphocytes before and under treatment with biologic drugs, and to assess their potential predictive value as biomarkers of response in rheumatoid arthritis (RA). METHODS: This was a non-randomised, single-centre, prospective study. Patients with active RA (American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) 2010) who required the initiation or switch to any biologic drug except rituximab were included. The main judgement criterion was the frequency and absolute number of CD24(hi)CD27(+) Breg and CD24(hi)CD38(hi) T2/Breg cells, CD25(hi)CD127(low) Treg and CD45RA(-)CD161(+)CCR6(+) Th17 cells measured at inclusion in both patients and controls, and after 1, 3 and 6 months of treatment (M1, M3 and M6) in patients with RA, and compared with the M6 response to treatment (EULAR response and Disease Activity Score in 28 joints (DAS28) remission). RESULTS: Thirty-one patients with RA and 17 controls were included. There was a reduction in T2/Breg frequency at M0 in patients (p < 0.001) and absolute numbers (p = 0.014) and in immunopositive vs. immunonegative RA (p = 0.016). DAS28 remission at M6 was associated with increased frequency of Treg (p = 0.01). A higher level of CD24(hi)CD27(+) Breg at baseline was associated with DAS28 remission at M6 (p = 0.04) and a good EULAR response at M6 for abatacept-treated patients (p = 0.01). A lower M0 level of Th17 was associated with a good EULAR response at M6 (p = 0.007), notably under anti-cytokine drugs (p = 0.048). CONCLUSIONS: Altogether, these data, although preliminary, suggest that phenotyping of T and B cells has potential value for the stratification of biologic drugs, notably with respect to choosing between abatacept and anti-cytokine blockade.
28626096 [Analgesic effect of buccal acupuncture on acute arthritis in rabbits and underlying mecha 2017 May 28 To observe the analgesic effect of acupuncture and to explore its central analgesic mechanism in rheumatoid arthritis rabbits.
 Methods: A total of 60 flap-eared white rabbits were randomly assigned into a normal control group (n=6), a model group (n=6), a body-acupuncture group (n=24), and a buccal acupuncture group (n=24). The later 2 groups were further randomly assigned into 0, 0.5, 1, and 2 h subgroups, with 6 cases in each group. The rheumatoid arthritis model was established by induction of egg-albumin. In the body acupuncture group, bilateral "Xiyan" and "Zusanli" were punctured for 15 s while in the buccal acupuncture group, acupuncture was applied to "Xi" for 15 s, with the needle retaining for 30 min. The pain threshold was detected with PL-200, taking struggle movements of rabbits as a measurement index, response latency from irradiation to struggling movements as the rabbit's pain threshold. The contents of β-endorplhin (β-EP) and cholecystokinin-8 (CCK-8) in cerebrospinal fluid were examined by radioimmunoassay.
 Results: Compared with the control group, pain threshold and CCK-8 levels decreased significantly (P<0.01) and the concentration of β-EP significantly increased (P<0.05) in the model group. The pain threshold in the body-acupuncture group and the buccal acupuncture group at 0 and 
1 h (P<0.05 or P<0.01) increased significantly, while the β-EP and CCK-8 contents in the body-acupuncture group and the buccal acupuncture group were significantly higher than those in the model group (P<0.01 or P<0.05). Both β-EP and CCK-8 contents in the buccal acupuncture group at 0 h were significantly higher than those in the body-acupuncture group (P<0.05).
 Conclusion: The analgesic effect of buccal acupuncture is superior to that of body-acupuncture. Both buccal acupuncture and body-acupuncture can effectively raise the pain threshold in acute arthritis rabbits, which is closely associated with their effects in the up-regulation of β-EP and CCK-8 contents in cerebrospinal fluid.
28893220 The added value of musculoskeletal ultrasound to clinical evaluation in the treatment deci 2017 Sep 11 BACKGROUND: Musculoskeletal ultrasound improves the accuracy of detecting the level of disease activity (DA) in RA patients, although its impact on the final treatment decision in a real clinical setting is uncertain. The objectives were to define the percentage of clinical scenarios from an ongoing cohort of RA outpatients in which the German Ultrasound Score on 7 joints (GUS-7) impacted the treatment and to explore if the impact differed between a senior rheumatologist (SR) vs. a trainee (TR). METHODS: Eighty-five consecutive and randomly selected RA outpatients underwent 170 assessments, 85 each by the SR and the TR. Initially, both physicians (blinded to each other) performed a rheumatic assessment and recommended a preliminary treatment. Then, the patients underwent the GUS-7 evaluation by an experienced rheumatologist blinded to clinical evaluations; selected joints of the clinically dominant hand were assessed by gray-scale and power Doppler (PD). In the final step, the TR and the SR integrated the GUS-7 findings with their previous evaluation and reviewed their recommendations. The patients received the final recommendation from the SR to avoid patient confusion. The study was approved by the Internal Review Board and all the patients signed informed consent. GUS-7 usefulness was separately evaluated by the SR and the TR according to a visual analogue scale (0 = not useful at all, 10 = very useful). Descriptive statistics were used. RESULTS: The patients were primarily middle-aged females (91.4%) with (mean ± SD) disease duration of 7.5 ± 3.9 years. The majority of them (69.2% according to TR and 71.8% to SR) were in DAS28-ESR-remission. In 34 of 170 clinical scenarios (20%), the GUS-7 findings modified the final treatment proposal; 24 of these scenarios were determined by the TR vs. 10 by the SR: 70.5% vs. 29.5%, p = 0.01. Treatment changes (increase, decrease and joint injection) were similar between both specialists. As expected, the TR rated the GUS-7 usefulness higher than the SR, particularly in the clinical scenarios where the GUS-7 findings impacted treatment. CONCLUSIONS: Musculoskeletal ultrasound added to standard rheumatic assessments impacted the treatment proposal in a limited number of patients; the impact was greater in the TR.
28286938 N-acetyl-l-cysteine controls osteoclastogenesis through regulating Th17 differentiation an 2019 Jan BACKGROUND/AIMS: This study aimed to determine the regulatory role of N-acetyl-l-cysteine (NAC), an antioxidant, in interleukin 17 (IL-17)-induced osteoclast differentiation in rheumatoid arthritis (RA). METHODS: After RA synovial fibroblasts were stimulated by IL-17, the expression and production of receptor activator of nuclear factor κ-B ligand (RANKL) was determined by real-time polymerase chain reaction and enzyme-linked immunosorbent assay (ELISA). Osteoclastogenesis was also determined after co-cultures of IL-17-stimulated RA synovial fibroblasts, Th17 cells and various concentrations of NAC with monocytes. After human peripheral CD4+ T cells were cultured with NAC under Th17 condition, IL-17, interferon γ, IL-4, Foxp3, RANKL, and IL-2 expression and production was determined by flow cytometry or ELISA. RESULTS: When RA synovial fibroblasts were stimulated by IL-17, IL-17 stimulated the production of RANKL, and NAC reduced the IL-17-induced RANKL production in a dose-dependent manner. NAC decreased IL-17-activated phosphorylation of mammalian target of rapamycin, c-Jun N-terminal kinase, and inhibitor of κB. When human peripheral blood CD14+ monocytes were cultured with macrophage colony-stimulating factor and IL-17 or RANKL, osteoclasts were differentiated, and NAC reduced the osteoclastogenesis. After human peripheral CD4+ T cells were co-cultured with IL-17-pretreated RA synovial fibroblasts or Th17 cells, NAC reduced their osteoclastogenesis. Under Th17 polarizing condition, NAC decreased Th17 cell differentiation and IL-17 and RANKL production. CONCLUSION: NAC inhibits the IL-17-induced RANKL production in RA synovial fibroblasts and IL-17-induced osteoclast differentiation. NAC also reduced Th17 polarization. NAC could be a supplementary therapeutic option for inflammatory and bony destructive processes in RA.
28366477 Biologic Therapies for Autoimmune and Connective Tissue Diseases. 2017 May Biologic therapy continues to revolutionize the treatment of autoimmune disease, especially in rheumatology as the pathophysiology of both inflammation and autoimmune disease becomes better understood. These therapies are designed to dampen the response of the inflammatory cascades. Although the first biologic therapies were approved many years ago, expanding indications and new agents continue to challenge the traditional treatment strategies for rheumatic diseases. This article reviews the data supporting the current use of biologic therapies, including off-label indications, in a subset of rheumatic diseases including rheumatoid arthritis, lupus, inflammatory myositis, ankylosing spondylitis, psoriatic arthritis, vasculitis, and gout.
27807003 Decreased flow-mediated dilatation in patients with rheumatoid arthritis: a meta-analysis. 2017 May OBJECTIVES: To derive a more precise comparison of flow-mediated dilatation (FMD%) of the brachial artery between patients with rheumatoid arthritis (RA) and normal controls by performing a meta-analysis of appropriate studies. METHODS: PubMed and EMBASE databases were searched for all relevant articles. STATA (V.12.0) software was used to perform the meta-analysis. Quality estimation of all appropriate studies was evaluated according to the Newcastle-Ottawa Scale (NOS). Standardised mean difference (SMD) with 95% CIs were calculated with a random-effects model. The Cochrane Q test and I(2) statistic were used to evaluate the heterogeneity. Funnel plot and Egger's test were conducted to assess the publication bias. RESULTS: In total, 464 articles were obtained after searching the two databases. Ten studies were included in the meta-analysis on the basis of the inclusion and exclusion criteria. Significant heterogeneity was observed among these 10 studies (Q=102.89, p<0.001, I(2)=91.3%) with random-effects modelling. The results showed that the RA group had significantly lower FMD% (SMD: -1.405; 95% CI -1.992 to -0.817; p<0.001) than the control group. Egger's test (p=0.004) indicated that the funnel plot showed a skewed or asymmetrical shape and publication bias existed. Sensitivity analyses suggested the robustness and credibility of our results. CONCLUSIONS: FMD% in patients with RA is significantly decreased compared with healthy controls. FMD% is an important early marker of atherosclerosis. It may be used as a parameter to forecast cardiovascular disease in patients with RA.
29065903 Changes in clinical disease activity are weakly linked to changes in MRI inflammation on t 2017 Oct 24 BACKGROUND: Rheumatoid arthritis (RA) treat-to-target (T2T) regimens often use the disease activity score (28 joints) incorporating C-reactive protein (DAS28(CRP)) as an outcome measure. We compared changes in the DAS28(CRP) with changes in magnetic resonance imaging (MRI) inflammation on treatment escalation. METHODS: Eighty seropositive RA patients with active disease were enrolled. Group A (N = 57) escalated to another conventional disease-modifying therapy (cDMARD) combination, and Group B (N = 23) to anti-TNF therapy/cDMARDs. Contrast-enhanced 3T-MRI wrist scans were obtained before and 4 months after regimen change. Scan pairs were scored for inflammation (MRI(i)) and damage. Disease activity was assessed using the DAS28(CRP). RESULTS: Eighty patients were enrolled and 66 MRI scan pairs were available for analysis. Intra-reader reliability was high: intraclass correlation coefficient (average) 0.89 (0.56-0.97). ΔDAS28(CRP) did not differ between groups: Group A, -0.94 (-3.30, 1.61); Group B, -1.53 (-3.59, 0.56) (p = 0.45). ΔMRI(i) also did not differ: Group A, 0 (-25, 10); Group B, -1 (-15, 28) (p = 0.12). Combining groups, ΔMRI(i) correlated weakly with ΔDAS28(CRP) (Spearman's 0.36, p = 0.003). Using multiple linear regression analysis adjusting for confounders, ΔDAS28(CRP) was associated with ΔMRI(i) (p = 0.056). Of the individual MRI measures, only Δtenosynovitis correlated with ΔDAS28(CRP) (Spearman's 0.33, p = 0.007). ΔMRI(i) was negatively associated with the MRI erosion score at entry (p = 0.0052). CONCLUSIONS: We report the first study investigating the link between changes in clinical and imaging inflammation in a real-world RA cohort escalating to conventional and biologic DMARDs. The association was significant but relatively weak, suggesting that MRI targets cannot yet be advocated as outcomes for T2T escalation. TRIAL REGISTRATION: ANZCTR 12614000895684 .

28706194 Anti-TNF-alpha agents and endothelial function in rheumatoid arthritis: a systematic revie 2017 Jul 13 Rheumatoid arthritis (RA) has been associated with endothelial dysfunction, a pathophysiological feature of atherosclerosis. Our aim was to determine whether TNF-α blockade has a beneficial effect on endothelial function in RA. We performed a systematic review with meta-analysis to evaluate the effect of anti-TNF-α agents on endothelial function in RA patients. MedLine, Cochrane CENTRAL and SCOPUS were searched up to March 2016. Inclusion criteria were: 1) randomised controlled trial (RCT), quasi-RCT, before-after cohort study; 2) including RA patients; 3) treatment with anti-TNF-α medications; 4) evaluating the change from baseline in endothelial function. The search strategy retrieved 180 records, of which 20 studies were included in the systematic review. Pooled analysis using a random-effects model demonstrated a significant improvement in endothelial function following anti-TNF-α treatment (SDM 0.987, 95%CI [0.64-1.33], p < 0.0001). Generalisation of the results of the meta-analysis may be limited due to the presence of heterogeneity (I2 = 82.65%, p < 0.001) and evidence of possible publication bias. Meta-regression showed that endothelial function measurement technique was a significant contributor to heterogeneity. In conclusion, although limited by the methodological quality of the included studies, our meta-analysis suggests that anti-TNF-α treatment may improve endothelial function in RA patients.
28441949 "It's so hard taking pills when you don't know what they're for": a qualitative study of p 2017 Apr 26 BACKGROUND: Patients with chronic illnesses are often required to take lifelong medication to alleviate symptoms and prevent disease progression. Many patients find it difficult to adhere to prescribed medication for various reasons, some of which may link to the way they conceptualise medicines and understand their illness and treatment. This study explores the medicine taking behaviours of patients presenting with Rheumatoid Arthritis (RA), a chronic inflammatory autoimmune disease. We focused particularly on patients' conceptualisation and understanding of medicines within this disease context, against a backdrop of scarce healthcare resources. METHODS: We conducted semi-structured interviews with 18 female patients at a rheumatology clinic in South Africa, as well as a review of participants' medical records. We conducted a secondary analysis of the data using thematic analysis and framework analysis principles. RESULTS: Participants reported a range of medicine taking behaviours including self-medicating, adding complementary and alternative medicines (CAM) or traditional remedies, and sometimes acquiring prescribed medicines illegally. Participants provided insights into their understanding of what constitutes a medicine and what substances can be added to a prescribed regimen, which impacted on adherence. Importantly, the majority of participants demonstrated poor understanding of their illness, medications, regimens and dosage instructions. CONCLUSIONS: Medicine taking in the context of RA, within the studied demographic, is complex and appears strongly mediated by individual and contextual factors. Poor patient understanding, individual conceptualisation of medicines and medicine taking, and the availability of a range of additional medicines and remedies impact on adherence. Based on these findings, we make some suggestions for how healthcare providers can play a greater role in educating patients living with RA about medicines, CAM and traditional remedies, as well as medicine taking behaviours.
27269650 Comparison of the Big Five personality traits in fibromyalgia and other rheumatic diseases 2017 Mar INTRODUCTION: The personality of patients with fibromyalgia is still under debate. Some studies found high neuroticism associated with low extraversion, while others found that these traits do not differ from the normal population. Personality factors intervene in the emotional regulation and modulation of pain. The aim of the study was to determine the personality traits of patients with fibromyalgia compared to other rheumatic diseases. METHODS: In a multicentric study, women with fibromyalgia, rheumatoid arthritis, spondyloarthritis or Sjögren's syndrome were asked to complete the Big Five Inventory, which encompasses five main personality dimensions, namely (1) extraversion vs. introversion, (2) agreeableness vs. antagonism, (3) conscientiousness vs. impulsivity, (4) neuroticism vs. emotional stability, and (5) openness vs. closed-mindedness. Variance analysis (Student's t-test and ANOVA with post-hoc comparisons or Bonferroni correction) was performed. We also conducted hierarchical and non-hierarchical cluster analyses. RESULTS AND DISCUSSION: Participants were 163 women with fibromyalgia (n=48), rheumatoid arthritis (n=46), spondyloarthritis (n=46) and Sjögren's syndrome (n=23). The mean age was 47.18years (±10.81years, range 21 to 65). Patients with fibromyalgia had higher scores on agreeableness (F(3, 159)=3.39, P<0.05), neuroticism (F(3, 159)=3.79, P<0.05) and openness (F(3, 159)=4.32, P<0.01) than those with other rheumatic diseases. This study highlights the specificity of personality in fibromyalgia. It also underlines the protective role of personality traits: in the fibromyalgia group, high neuroticism and low conscientiousness (high impulsivity) were associated with a high level of chronic pain.
28986633 [The rheumatic cervical spine]. 2017 Dec BACKGROUND: The cervical spine is one of the main sites of manifestation in rheumatoid arthritis outside of the extremities. It can have a decisive influence on disease course via the occurrence of mechanical instabilities as well as neurologic symptoms. Both adequate diagnosis and the corresponding surgical treatment represent a challenge for the involved physicians. MATERIALS AND METHODS: This review presents relevant diagnostic strategies and possibilities for surgical intervention which aim to avoid potentially fatal neurologic symptoms. Basic literature and expert opinions are also discussed. RESULTS AND CONCLUSION: Through target-oriented surgical management, as well as tight clinical and radiologic monitoring during conservative and surgical therapy, potentially fatal disease courses can be avoided.
