| 30417444 | The triptolide-induced apoptosis of osteoclast precursor by degradation of cIAP2 and treat | 2019 Feb | This study aims to discuss the effect of triptolide (TPL) on rheumatoid arthritis (RA) and the mechanism related to osteoclast precursor (OCP) and osteoclast (OC). TNF-transgenic RA mice were treated with different doses of TPL by gavage. After the administration was finished, the curative effects were evaluated and compared, and the OCP apoptosis rates, the OC number, and the OC differentiation ability in vitro were detected. Finally, splenocytes of wild-type mice were cultured in vitro and induced to differentiate into OCP, and the cell apoptosis rate, cIAP2, and apoptotic effectors expression level were detected after cIAP2 overexpression and TPL administration. After TPL administration, the RA symptoms in the TPL groups were all better, the apoptosis rate of OCP was higher, and the amount of OC in vitro were lower than that in the control group (all PÂ <Â 0.05), and all of the changes in the high-dose group were more obvious than the low-dose group. In splenocytes cells cultured in vitro, cIAP2 overexpression could decrease the apoptosis rate of OCPs and increase the OC number, and TPL treatment could down-regulate the cIAP2 and promote OCP apoptosis and OC reduction. In conclusion, TPL could induce OCP apoptosis and inhibit OC formation to effectively treat RA by mediating cIAP2 degradation. | |
| 30175668 | Evaluation of factors associated with locomotive syndrome in Japanese elderly and younger | 2019 Sep | Objectives: We aimed to determine the prevalence of locomotive syndrome (LS) using the 25-question geriatric locomotive function scale (GLFS-25) and identify factors associated with LS in elderly and younger patients with rheumatoid arthritis (RA). Methods: Overall, 390 patients with RA who underwent GLFS-25 measurement, bone mineral density determination, and bioelectrical impedance analysis were enrolled. Factors associated with LS were analyzed by comparing patients with and without LS among both elderly and younger patients with RA. Results: The prevalence of LS was 41.5%, 47.7% and 32.3% in all patients, elderly patients, and younger patients with RA, respectively. Pain visual analog scale (VAS) and Health Assessment Questionnaire Disability Index (HAQ-DI) were associated with LS in both elderly and younger patients. Moreover, in younger patients with RA, disease activity score in 28 joints (DAS28), erythrocyte sedimentation rate (ESR), basal metabolic rate, and legs muscle mass were identified as being associated with LS. Conclusion: This study demonstrated that to prevent LS, we should aim to control pain and maintain a low HAQ-DI in elderly and younger patients with RA, and improve disease activity and maintain a higher basal metabolic rate, and legs muscle mass in younger patients with RA. | |
| 29533754 | Trends in the activity of rheumatoid arthritis as the consequence of treat-to-target strat | 2018 Sep | OBJECTIVES: To investigate the trends in the activity of rheumatoid arthritis (RA) over the past 8 years and evaluate the value of treat-to target (T2T) strategy in daily practice. METHODS: All the medical records of RA patients from 2009 to 2016 were retrospectively reviewed. Disease activity scores at obtained visits were measured by DAS28-CRP, DAS28-ESR, SDAI and CDAI. To display trends over years, both mean and time-adjusted methods were applied in calculation of annual disease activity and remission rate. Disease activity and remission rate were also compared before and after the year 2011 when application of T2T strategy was initiated in our centre. Furthermore, a sub-cohort study including T2T and non-T2T period groups was conducted with outcome of cumulative percentage of remission and time to achieve first remission during the first year follow-up. RESULTS: In total, 1,001 patients with 6,944 clinical visits were included. Over an eight-year period, significant improvements were witnessed in disease activity and remission rate, measured by all four indices (p<0.0001). More patients achieved lower disease activity and higher remission rates after T2T adherence in 2011 compared to those in the years 2009 and 2010 (p<0.0001). Moreover, sub-cohort study revealed that more patients (49.3-73.2% vs. 19.1-34.5%, OR=2.4-3.0) achieved remission with a shorter median time compared with the non-T2T period group (p<0.0001), particularly in DAS28-CRP (21 vs. >52 weeks), DAS28-ESR (37 vs. >52 weeks). CONCLUSIONS: Over the past 8 years, the RA activity has substantially decreased and T2T strategy was directly attributable to the favourable changes in clinical practice. | |
| 29481842 | A novel gene and pathway-level subtyping analysis scheme to understand biological mechanis | 2019 May | Complex diseases have heterogeneous underlying molecular mechanisms. In order to improve the diagnosis and treatment of disease, it is vital to stratify patients into homogeneous subgroups that share a similar disease etiology. In this study, we performed gene-level subtyping analysis on two independent Rheumatoid Arthritis gene expression cohorts from different ethnic groups to discover the possible disease mechanisms associated with each subtype. Also, a novel pathway-level analysis is proposed to increase the subtyping robustness and facilitate biological interpretation. This approach could stratify RA patients into two robust and homogeneous groups with differing activation of central signal transduction pathways and pro-inflammatory cytokines in the pathogenesis of RA. Such a methodology can help understand disease mechanisms at play in different patient sub-populations and also potentially explain why some patients don't respond to anti-TNF treatment. | |
| 28322506 | Hand functions in systemic sclerosis and rheumatoid arthritis and influence on clinical va | 2018 Jan | AIM: Hand joints are the main target in rheumatoid arthritis (RA) and hand involvement in terms of thickening of the skin and contractures are also well known in systemic sclerosis (SSc). Assessment of hand function in SSc is generally an overlooked entity with respect to RA. Therefore the aim of this study was to compare hand functions and potential influence of functional loss on patients' overall physical functions, health-related quality of life (HRQoL) and psychological status in RA and SSc. METHODS: Age- and gender-matched adult patients with SSc and RA were consecutively recruited. Patients' hand functions were evaluated by using the Duruöz Hand Index (DHI), and hand span and hand grip strength were measured. Patients were evaluated for disease-specific and generic outcome measures including disease activity parameters and HRQoL measures. RESULTS: Fifty patients (44 female, six male) with SSc and 51 (45 female, six male) with RA were included. Despite similar functioning and HRQoL, patients with RA had higher visual analog scale-pain and body mass index. In both groups DHI revealed similar functional loss and correlated with various measurements related to HRQoL. In SSc, hand span, grip strength and modified Rodnan skin score had major influences on hand functions. CONCLUSION: Assessment of hand function is an important component in the clinical evaluation of patients with RA and SSc. Loss of hand functions is an important feature contributing negatively to the overall physical status and HRQoL in patients with SSc and may be more frequent and important than expected. | |
| 29940971 | Are aortic coarctation and rheumatoid arthritis different models of aortic stiffness? Data | 2018 Jun 26 | BACKGROUND: Patients who underwent a successful repair of the aortic coarctation (CoA) show high risk for cardiovascular (CV) events. Mechanical and structural abnormalities in the ascending aorta (Ao) might have a role in the prognosis of CoA patients. We analyzed the elastic properties of Ao measured as aortic stiffness index (AoSI) in CoA patients in the long-term period and we compared AoSI with a cohort of 38 patients with rheumatoid arthritis (RA) and 38 non-RA matched controls. METHODS: Data from 19 CoA patients were analyzed 28 ± 13 years after surgery. Abnormally high AoSI was diagnosed if AoSI > 6.07% (95th percentile of the AoSI detected in our reference healthy population). AoSI was assessed at the level of the aortic root by two-dimensional guided M-mode evaluation. RESULTS: CoA patients showed more than two-fold higher AoSI compared to RA and controls (9.8 ± 12.6 vs 4.8 ± 2.5% and 3.1 ± 2.0%, respectively; all p < 0.05 and in 5 of 19 patients with CoA (26%) AoSI was exceptionally high. The 5 patients with abnormally high AoSI were older with higher BP, LV mass and prevalence of LV diastolic dysfunction. Multiple linear regression analysis revealed that AoSI was independently related to the presence of LV hypertrophy and higher LV relative wall thickness. CONCLUSIONS: CoA patients have higher AoSI levels than RA patients and non-RA matched controls. AoSI levels are abnormally high in a small sub-group of CoA patients who show a very high-risk clinical profile for adverse CV events. | |
| 30019084 | LRP5 gene polymorphisms and radiographic joint damage in rheumatoid arthritis patients. | 2018 Oct | Rheumatoid arthritis (RA) is characterized by increased bone resorption and impaired bone formation. Osteoblast function is regulated by the canonical LRP5/Wnt/β-catenin pathway. Bone mineral density and RA joint destruction are partially inherited. In line with this, we found significant associations between LRP5 SNPs (p.A1330V, p.N740N, p.V667M) and RA radiographic damage severity. INTRODUCTION: Increased bone resorption and impaired bone formation characterize rheumatoid arthritis (RA). Canonical Wnt/β-catenin pathway, signalled by lipoprotein receptor-related protein-5 (LRP5), regulates osteoblast function. Since bone mineral density (BMD) and RA joint destruction are partially inherited, we studied their association with LRP5 single nucleotide polymorphisms (SNPs). METHODS: Clinical data and peripheral blood for biomarkers assessment and LRP5 genotyping were collected from 208 RA patients. Hands and feet X-rays were scored [modified Sharp/van der Heijde Score (SHS), joint space narrowing (JSN), and erosion scores]. Lumbar spine, total left proximal femur, and left hand BMD were assessed by dual-energy X-ray absorptiometry (DXA). RESULTS: TT genotypes for p.A1330V and p.N740N LRP5 SNPs associated with total SHS, erosion score, and hands erosion score; the same for p.A1330V with feet JSN score and p.N740N with hands total score. AG genotype for p.V667M associated with sclerostin and hands JSN score. Femoral BMD associated with TC genotype for p.N740N. Multiple test correction precluded a few of these associations. Among V667M-N740N-A1330V haplotypes: GTT associated with higher feet JSN score (OR = 3.80; p = 0.016) and ATT with higher JSN score (OR = 4.60; p = 0.032), hands total score (OR = 5.65; p = 0.022), and total SHS (OR = 6.74; p = 0.024). CONCLUSION: Significant associations between LRP5 SNPs (p.A1330V, p.N740N, and p.V667M) and the severity of radiographic damage reinforce the evidence of bone destruction heritability in RA. | |
| 28544615 | Suppressing Inflammation in Rheumatoid Arthritis: Does Patient Global Assessment Blur the | 2018 Mar | OBJECTIVE: In current management paradigms of rheumatoid arthritis (RA), patient global assessment (PGA) is crucial to decide whether a patient has attained remission (target) or needs reinforced therapy. We investigated whether the clinical and psychological determinants of PGA are appropriate to support this important role. METHODS: This was a cross-sectional, single-center study including consecutive ambulatory RA patients. Data collection comprised swollen 28-joint count (SJC28), tender 28-joint count (TJC28), C-reactive protein (CRP) level, PGA, pain, fatigue, function, anxiety, depression, happiness, personality traits, and comorbidities. Remission was categorized using American College of Rheumatology/European League Against Rheumatism Boolean-based criteria: remission, near-remission (only PGA >1), and nonremission. A binary definition without PGA (3v-remission) was also studied. Univariable and multivariable analyses were used to identify explanatory variables of PGA in each remission state. RESULTS: A total of 309 patients were included (remission 9.4%, near-remission 37.2%, and nonremission 53.4%). Patients in near-remission were indistinguishable from remission regarding disease activity, but described a disease impact similar to those in nonremission. In multivariable analyses, PGA in near-remission was explained (R(2)(adjusted) = 0.50) by fatigue, pain, anxiety, and function. Fatigue and pain had no relationship with disease activity measures. CONCLUSION: In RA, a consensually acceptable level of disease activity (SJC28, TJC28, and CRP level ≤1) does not equate to low disease impact: a large proportion of these patients are considered in nonremission solely due to PGA. PGA mainly reflects fatigue, pain, function, and psychological domains, which are inadequate to define the target for immunosuppressive therapy. This consideration suggests that clinical practice should be guided by 2 separate remission targets: inflammation (3v-remission) and disease impact. | |
| 30398030 | IL-17A haplotype confers susceptibility to systemic lupus erythematosus but not to rheumat | 2019 Mar | AIM: Recent studies highlight the importance of the interleukin (IL)-17A cytokine in systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). There are also reports of associations between some single nucleotide polymorphisms (SNPs) in IL-17A and RA but not SLE. Notably, these findings have not been replicated in all studied populations. The aim of this study was to investigate whether the IL-17A -737Â T/C (rs8193036), -444A/G (rs3819024), -197G/A (rs2275913), and -121G/A (rs8193037) SNPs conferred susceptibility to SLE (or lupus nephritis) or to RA in a Mexican population. METHODS: The study included 1367 Mexican subjects, 501 with RA, 367 with SLE, and 499 healthy controls. IL-17A was genotyped using a TaqMan 5' allelic discrimination assay. RESULTS: Our results showed that the IL-17A -737Â T/C, -444A/G, -197G/A, and -121G/A SNPs had similar genotype and allele frequencies in patients with SLE (or lupus nephritis) or RA and in controls. However, an IL-17A haplotype (TAGA) showed an association with SLE susceptibility (odds ratio 2.43, PÂ =Â 0.004) but not with RA susceptibility. CONCLUSIONS: These results confirm that the IL-17A -737T/C, -444A/G, -197G/A, and -121G/A SNPs are not risk factors for RA, but the IL-17A TAGA haplotype is a risk factor for SLE. This is the first report to document an association between IL-17A and SLE susceptibility in adults. | |
| 30168272 | Efficacy of abatacept tapering therapy for sustained remission in patients with rheumatoid | 2019 Jan | AIM: To investigate whether remission can be sustained for rheumatoid arthritis (RA) patients after tapering abatacept (ABT). METHOD: All patients were naïve to biological disease-modifying anti-rheumatic drugs (bDMARDs) and in low or moderate Disease Activity Score of 28 joints with C-reactive protein (DAS)28-CRP). ABT was administrated intravenously (IV) or subcutaneously (SC) for 36 weeks to patients with RA, who had not previously received bDMARDs. As the ABT tapering protocol, ABT was administrated SC at 125 mg every 2 weeks for 12 weeks in patients with remission. RA disease activity was assessed by DAS28-CRP and ultrasonography. Remission was assessed by defining it as DAS28-CRP <2.3. RESULTS: Of the 51 patients, 84.3% were women (mean age 68.7 ± 10.2 years, mean disease duration 7.7 ± 10.2 years). Twenty-nine patients achieved remission and a power Doppler (PD) score ≤1 at each joint at 36 weeks, followed by tapering ABT. Of these patients, 25 sustained DAS28-CRP remission, and DAS28-CRP was not significantly elevated (1.62 ± 0.41 to 1.69 ± 0.49) at 48 weeks, but the total PD score was significantly elevated (1.52 ± 1.21 to 2.59 ± 2.81 P = 0.049). Longer disease duration, higher DAS28-CRP at 24 weeks, and higher total PD score at 24 weeks were predictors of an elevated total PD score after tapering ABT therapy. CONCLUSION: These findings suggest that ABT tapering is a promising short-term strategy to sustain remission in patients with RA, and ultrasonography is a useful tool for monitoring disease activity after tapering ABT. | |
| 30341703 | Remission rate and predictors of remission in patients with rheumatoid arthritis under tre | 2019 Mar | This systematic review and meta-analysis aim to evaluate the remission rate of patients with rheumatoid arthritis (RA) in real-world studies and to summarize potential predictors of remission in RA. Studies reporting remission rate in patients with RA were searched from MEDLINE, EMBASE, and Scopus databases. Two reviewers independently assessed all studies according to eligibility criteria and extracted data. Generally, observational studies reporting remission rate in adult (≥ 18 years) patients with RA were included. Quality assessments were performed using the Newcastle-Ottawa Scale. Pooled analyses of remission rate were conducted using a random-effects model and data were analyzed in subgroups to identify potential source of heterogeneity. Sensitivity analyses were performed by serially excluding each study. Potential predictors of remission were summarized. Thirty-one studies with ~ 82,450 RA patients in total were included. Using the DAS28 remission criteria, the pooled 3-, 6-, 12-, and 24-month remission rates were 17.2%, 16.3%, 21.5%, and 23.5%, respectively. Subgroup analyses showed that 11.7% and 13.8% of TNFi inadequate responders reached remission after 6- and 12-month use of non-TNFi biologics. Predictors of remission included male, higher education level, and lower baseline disease activity, while initial use of corticosteroids was negative predictors of remission. Sustained remission was rare regardless of different criteria used. Remission was a reachable target in real-world studies, while attention should also be paid to achieve sustained remission. | |
| 29884751 | Ability of disease-modifying antirheumatic drugs to prevent or delay rheumatoid arthritis | 2018 Aug | BACKGROUND: Recent advances in knowledge of the pathogenesis of rheumatoid arthritis (RA) has led to promoting very early intervention. OBJECTIVES: To assess the efficacy of therapeutic interventions in preventing or delaying RA onset with a systematic literature review (SLR) and meta-analysis (MA). METHODS: The SLR aimed to include all reports of randomised controlled trials of disease-modifying antirheumatic drugs or glucocorticoids used in patients presenting genetic and/or environmental risk factors for RA and/or systemic autoimmunity associated with RA, and/or symptoms without clinical arthritis and/or unclassified arthritis and in patients with RA. We searched PubMed, EMBASE and Cochrane databases for English articles published from 2006 to 2016 using the keywords 'undifferentiated arthritis' or 'very early rheumatoid arthritis' with 'therapy' or 'treatment'. Main outcome was RA occurrence, defined as fulfilment of the 1987 ACR criteria. The MA was performed with RevMan with the Mantel-Haenszel method. RESULTS: Among 595 abstracts screened, 10 reports of trials were selected. The studies included 1156 patients, with mean symptom duration 16.2±12.6 weeks. The occurrence of RA was available for nine studies, assessing methylprednisolone, methotrexate, a tumour necrosis factor blocker, abatacept or rituximab. In the group arthralgia without arthritis (people at risk of RA), the MA of the two available studies did not show significant reduction in RA occurrence at week 52 or more (pooled OR 0.74, 95% CI 0.37 to 1.49). For people with undifferentiated arthritis, the MA of the seven available studies revealed significant risk reduction with OR 0.73(95% CI 0.56 to 0.97). CONCLUSIONS: This MA demonstrates that early therapeutic intervention may significantly reduce the risk of RA onset in this very first phase of the disease. | |
| 28512992 | Association of CD8(+) T-cells with bone erosion in patients with rheumatoid arthritis. | 2018 Feb | AIM: Bone erosion is a major problem worsening quality of rheumatoid arthritis (RA) patients' lives. However, causal factors responsible for bone erosion in RA have remained unclear. We aimed to examine genetic variants conferring bone erosion in RA using a Korean genome-wide association study (GWAS) and to search for possible biological mechanisms underlying the development of bone erosion. METHOD: We obtained genome-wide single nucleotide polymorphism (SNP) data for 711 Korean RA patients using Illumina HapMap 550v3/660W arrays. Associations between SNPs and bone erosion status based on the Steinbrocker staging system were examined using multivariate logistic regression. Cell-type-specific enrichment of the epigenomic chromatin annotation H3K4me3 at the bone erosion associated variants was further investigated using National Institute of Health Roadmap Epigenomics data. RESULTS: As we tested the associations between 439 289 SNPs and bone erosion in 385 patients with erosive RA and 326 with non-erosive RA, none of the tested SNPs reached the genome-wide significance threshold, although many loci showed modest genetic effect on bone erosion status with suggestive association (e.g., rs2741200 [P = 3.75 × 10(-6) ] in the SLA-TG locus and rs12422918 [P = 4.13 × 10(-6) ] in SRGAP1). However, the top-ranked SNPs and their linked proxies, which were mostly located in non-coding variants, were significantly co-localized with the highly tissue-specific regulatory marker H3K4me3 in CD8(+) memory T-cells (P = 0.014). CONCLUSION: Although, there was no large-effect variants associated with bone erosion in our GWAS, we have shown that CD8(+) memory T-cells may have relevance with bone erosion in patients with RA through the analysis of ChiP-seq data. | |
| 29609204 | Aerobic Exercise and Fatigue in Rheumatoid Arthritis Participants: A Meta-Analysis Using t | 2018 Dec | OBJECTIVE: To use the minimal important difference (MID) versus the standardized mean difference (SMD) approach in order to provide more robust and clinically relevant information regarding the association between land-based aerobic exercise and changes in self-reported fatigue among adults with rheumatoid arthritis (RA). METHODS: Data from a previous meta-analysis of 5 randomized controlled trials that represented up to 298 participants per study were utilized to calculate 9 effect sizes, using the MID approach. Data used to obtain the MID were derived from previously reported anchor-based values specific to each fatigue instrument in adults with RA. Results were pooled using a random-effects model. RESULTS: Aerobic exercise resulted in statistically significant reductions in self-reported fatigue (MID effect size -0.34 [95% confidence interval (95% CI) -0.58, -0.10]; P = 0.006). Results were similar when effect sizes were collapsed so that only 1 effect size represented each study (MID effect size -0.39 [95% CI -0.76, -0.03]; P = 0.04). CONCLUSION: Land-based aerobic exercise is associated with statistically significant reductions in fatigue; however, based on previous cut points, it may be unlikely that a substantial number of participants with RA could obtain clinically relevant reductions in fatigue. Additional studies are needed, especially in those individuals with RA who have elevated levels of fatigue. | |
| 29057700 | Polymorphic lymphoproliferative disorders in patients with rheumatoid arthritis are associ | 2018 Jul | OBJECTIVES: The characteristics of lymphoproliferative disorders (LPD) in patients with rheumatoid arthritis (RA) remain unclear. Therefore, we retrospectively analyzed the clinical characteristics of these patients in our department. METHODS: Twenty RA patients who developed LPD between April 2003 and August 2016 in our department were analyzed. RESULTS: All of the RA patients who developed LPD had been treated with methotrexate (MTX). The median weekly and total dosages of MTX were 6.8 mg/week and 2530 mg, respectively. The median duration of MTX administration was eight years. Nineteen patients (95%) achieved complete remission (CR) and 15 (75%) achieved CR with MTX cessation alone. Based on the pathological findings, we divided MTX-associated LPD patients into two groups (n = 16); polymorphic LPD (31%) and other groups. CR with MTX cessation alone was achieved in 5 (100%) and 6 (54.5%) patients in the polymorphic LPD and other groups, respectively (p = .12). Moreover, the duration from the cessation of MTX to CR was significantly shorter in the polymorphic LPD group than in the other group (5.3 months vs 12.6 months, p = .01, respectively). CONCLUSION: Polymorphic LPD, which was the most frequent pathological diagnosis in this cohort, was associated with a higher incidence of CR and a significantly shorter duration to CR. | |
| 28612349 | Role of hydrotherapy in the amelioration of oxidant-antioxidant status in rheumatoid arthr | 2018 Oct | AIM: Rheumatoid arthritis (RA) is an inflammatory autoimmune disease. Reactive oxygen species (ROS) are involved in the pathophysiology of RA. Moderate intensity exercises have been reported to have anti-oxidant and anti-inflammatory effects. The aim of this study was to evaluate the effect of hydrotherapy on oxidant-antioxidant status in RA patients. METHODS: Forty RA patients and 30 age- and sex-matched healthy controls were included in this study. RA patients were subdivided into two groups: the first group (n = 20) received treatment with conventional RA drugs, while the second group (n = 20) received hydrotherapy along with the conventional drugs for a period of 12 weeks. Disease Activity Score of 28 joints (DAS-28), ROS level, protein oxidation, lipid peroxidation, DNA damage and the activities of antioxidant enzymes were evaluated before and after 12 weeks of treatment. RESULTS: RA patients showed a significant change in the oxidative stress biomarkers (ROS, P < 0.01; ferric reducing antioxidant potential, P < 0.001; malondialdehyde, P < 0.01; protein carbonyl, P < 0.001; tail length, P < 0.05) and decrease in the activities of anti-oxidant enzymes (superoxide dismutase [SOD], P < 0.01; glutathione peroxidase [GPx], P < 0.001). Conventional drug treatment has not produced any significant change in these parameters. However, cotreatment of drugs with hydrotherapy has decreased protein, lipid and DNA oxidation by increasing the activities of antioxidant enzymes (SOD and GPx). CONCLUSION: Our results indicate that hydrotherapy along with drugs has reduced the severity of disease (DAS-28) by ameliorating the oxidant-antioxidant status in RA patients. Thus, in addition to conventional drugs, RA patients should be advised to have hydrotherapy (moderate intensity exercise) in their treatment regimen. | |
| 29330703 | Association Between Atrial, Ventricular and Vascular Morphofunctional Alterations in Rheum | 2018 Mar | INTRODUCTION: Rheumatoid arthritis (RA) represents a risk of non-fatal and cardiovascular events. The aim of the present study was to evaluate simultaneously left and right atrial and ventricular function, as well as arterial stiffness, in RA patients. METHODS: This cross-sectional study included 55 consecutive RA patients and 55 healthy age and gender-matched controls. Blood pressure and arterial stiffness were assessed in all participants, who also underwent a complete echocardiographic examination. RESULTS: RA patients were treated with steroid therapy (52.7%), methotrexate (66.6%) and biological therapy (54.5%). Disease activity score revealed low average RA activity. Augmentation index was significantly higher in RA patients (32.2 ± 8.6 vs. 28.4 ± 8.9%, P = 0.02). Left atrial volume was also higher among RA patients (23.1 ± 8.2 vs. 20.1 ± 7.1 ml/m(2), P = 0.04), whereas mitral and tricuspid E/A ratios were significantly lower in RA individuals (0.90 ± 0.24 vs. 1.03 ± 0.35, P = 0.02; 1.07 ± 0.31 vs. 1.27 ± 0.35, P = 0.003, respectively). Tissue Doppler systolic and diastolic velocities were similar between the observed groups. Arterial stiffness index showed significant correlation with disease duration (r = 0.29; P = 0.03). Tissue Doppler-derived transmitral late diastolic velocity (A') showed significant correlation with index of disease activity in the RA patients. CONCLUSIONS: Our results showed that left and right ventricular diastolic function and arterial stiffness were significantly deteriorated in the RA patients comparing with controls. The assessment of left and right ventricular diastolic function, as well as vascular function, should be an essential part of clinical evaluation in the RA patients. | |
| 28029551 | Recommendations for the use of ultrasound and magnetic resonance in patients with rheumato | 2018 Jan | OBJECTIVE: To develop evidence-based recommendations on the use of ultrasound (US) and magnetic resonance imaging (MRI) in patients with rheumatoid arthritis (RA). METHODS: Recommendations were generated following a nominal group technique. A panel of experts, consisting of 15 rheumatologists and 3 radiologists, was established in the first panel meeting to define the scope and purpose of the consensus document, as well as chapters, potential recommendations and systematic literature reviews (we used and updated those from previous EULAR documents). A first draft of recommendations and text was generated. Then, an electronic Delphi process (2 rounds) was carried out. Recommendations were voted from 1 (total disagreement) to 10 (total agreement). We defined agreement if at least 70% of experts voted ≥7. The level of evidence and grade or recommendation was assessed using the Oxford Centre for Evidence-based Medicine Levels of Evidence. The full text was circulated and reviewed by the panel. The consensus was coordinated by an expert methodologist. RESULTS: A total of 20 recommendations were proposed. They include the validity of US and MRI regarding inflammation and damage detection, diagnosis, prediction (structural damage progression, flare, treatment response, etc.), monitoring and the use of US guided injections/biopsies. CONCLUSIONS: These recommendations will help clinicians use US and MRI in RA patients. | |
| 28486047 | Prevalence of metabolic syndrome in rheumatoid arthritis patients from Northeastern Brazil | 2018 Mar | OBJECTIVES: To determine the prevalence of metabolic syndrome (MetS) in patients with rheumatoid arthritis (RA) and controls from Northeastern Brazil and to verify its association with specific RA parameters and cardiovascular risk factors. METHODS: The prevalence of MetS was assessed cross-sectionally in 338 RA patients from a single center and 84 age and gender-matched controls from the local community. MetS was defined according to NCEP/ATPIII guidelines. Disease activity was assessed with CDAI, SDAI and DAS28 scores. Independent risk factors for MetS in RA patients were identified by multivariate logistic regression. RESULTS: The prevalence of MetS was higher in RA patients than in controls (51.3% vs. 21.8%; p < .001). RA patients had a higher frequency of hypertension and type-2 diabetes mellitus, greater waist circumference (WC), higher blood glucose levels and lower HDL levels. DAS28, CDAI and SDAI scores were higher and high disease activity was more frequent in MetS patients. The multivariate logistic regression identified BMI (OR = 1.12, 95% CI = 1.05-1.20; p < .001) and disease activity (OR = 1.23, 95% CI = 1.04-1.47; p = .016) as independent risk factors for MetS in patients with RA. CONCLUSION: RA in patients from Northeastern Brazil was found to be associated with increased WC, high prevalence of MetS (one of the highest in the world) and disease activity. Patients with MetS displayed a higher frequency of cardiovascular risk factors, indicating the need for better control of disease activity and modifiable risk factors for cardiovascular disease (CVD). | |
| 29700971 | Can a disaster affect rheumatoid arthritis status? A retrospective cohort study after the | 2018 Jun | OBJECTIVE: As status of rheumatoid arthritis (RA) is highly affected by environmental factors, a catastrophic disaster may also affect RA activity. Herein we conducted a retrospective cohort study in the disaster area of the 2011 triple disaster in Fukushima, Japan: an earthquake, tsunamis and a nuclear accident. METHODS: Clinical records of RA patients who attended a hospital near the Fukushima Daiichi Nuclear Power Plant were collected. For those who underwent whole-body counter testing, internal radiation exposure levels were also collected. As clinical parameters may fluctuate in the absence of a disaster, changes in values before and after the disaster were also compared. Logistic regression was conducted to identify factors affecting RA status. RESULTS: Fifty-three patients (average age, 64.2 years; females, 83%; average disease duration, 15.7 years) were included in the study. Five patients lived within the no-entry zone, 37 evacuated immediately after the disaster, and four temporarily stopped RA treatment. The proportions of patients who showed worsened tender joint counts, swollen joint counts and rheumatoid factor values were significantly higher after the disaster compared to those before. Among the 16 patients who underwent whole-body counter testing, only one showed a detectable, but negligible, radioactive cesium level. Use of methotrexate was identified as a possible preventive factor for RA exacerbation in this setting. CONCLUSION: This is the first study to analyze detailed profiles of RA patients after a disaster. As methotrexate may prevent disease exacerbation, continuity of care for this common chronic disease should be considered in disaster settings. |
