29508003 | [Pharmacological treatment of rheumatoid arthritis and its comorbidities]. | 2018 Apr | Due to therapeutic advances, rheumatoid arthritis (RA) today has developed into a satisfactorily treatable disease in most cases, with remission being the target of treatment. Early diagnosis with immediate treatment initiation following treat-to-target strategy is the key to a favorable long-term outcome. A guideline-directed treatment algorithm determines the use of conventional synthetic disease-modifying anti-rheumatic drugs (DMARD; e.g., methotrexate), biological DMARD, and targeted oral DMARD (Janus kinase inhibitors). Comorbidities-in particular cardiovascular and interstitial lung disease-affect 80% of RA patients and represent the leading causes for mortality. The choice of drug treatment is influenced by the presence of comorbidities. | |
30005856 | Inflammation and dementia: Using rheumatoid arthritis as a model to develop treatments? | 2018 Sep | Dementia is a major international public health problem which looks set to grow as the ageing population increases. Despite large amounts of investment there has been relatively little progress in developing new therapies to combat this. There is a growing body of evidence that both local and systemic inflammation are important in dementia; with cerebral inflammation occurring secondarily to beta-amyloid plaques, raised levels of serum inflammatory molecules and cytokines being present in Alzheimer's disease patients and systemic inflammation being associated with cerebral microvasculature disease in vascular dementia. Observational studies had suggested that non-steroidal anti-inflammatory drugs may reduce the risk of dementia, but subsequent interventional studies have been disappointing. More recently some observational studies have suggested a protective effect from conventional synthetic disease modifying anti-rheumatic drugs (csDMARDS) and tumour necrosis factor inhibiting (TNFi) biological therapies. Treatments for inflammatory rheumatic diseases have previously been repurposed and used successfully in other diseases, such as TNFi for inflammatory bowel disease. There are also studies looking at the use of csDMARDs such as methotrexate to improve outcomes after cardiovascular events. Ongoing interventional trials are currently looking at whether therapies designed to treat inflammatory and autoimmune diseases have the potential to be used to treat dementia. | |
30002215 | Neutropaenia and splenomegaly without arthritis: think rheumatoid arthritis. | 2018 Jul 11 | Felty syndrome(FS) is an uncommon, but severe, extra-articular manifestation of rheumatoid arthritis (RA). It occurs in patients with longstanding RA. It is extremely rare for RA to present as FS or develop after initially presenting as neutropaenia and splenomegaly. We describe a case of 47-year-old woman who was diagnosed simultaneously with FS and possible RA after testing positive for anticyclic citrullinated peptide antibody, but a negative rheumatoid factor. She had an excellent response to methotrexate. We review the existing literature of such cases and emphasise the importance of serological testing for RA in patients presenting with neutropaenia and splenomegaly, even in the absence of joint symptoms or prior diagnosis of RA. | |
30375970 | [Diagnosing and treating rheumatoid arthritis]. | 2018 Oct 29 | Rheumatoid arthritis (RA) is a chronic, autoimmune joint disease associated with increased risk of multiorgan involvement and comorbidities such as osteoporosis, cardiovascular disease, and infections. Therefore, doctors in other specialities should have knowledge of RA. No diagnostic criteria are available, but the classification criteria are often used as a diagnostic tool. Early initiation of effective immunosuppressive treatment is essential to improve outcome. The cornerstone of treatment is intra-articular administration of glucocorticoids in combination with methotrexate. | |
30047807 | New strategies for patenting biological medicines used in rheumatoid arthritis treatment. | 2018 Aug | INTRODUCTION: Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by an inflammatory process, with a global prevalence ranging from 0.3% to 1%. The overall cost of RA drugs is estimated in $20 billion worldwide and projected to grow to $36 billion by 2021. The current RA treatment strategy consists of the aggressive therapy directed to specific targets, after diagnostic confirmation and the stepped therapy directed by the stage of the disease, aiming at the clinical remission. Conventional (methotrexate, sulfasalazine, leflunomide) and biological (infliximab, adalimumab, tocilizumab) disease-modifying antirheumatic drugs may fail, produce only partial responses, or unwanted side effects, and consequently new antirheumatic drugs are being developed to overcome these limitations. AREAS COVERED: In this review, the authors described the technological trends and the main players involved in the R&D process related to biological compounds employed in the treatment of RA, using patent documents as a source of technological information. EXPERT OPINION: Current treatments for RA still mainly target the immune system, different inflammatory targets, and mediators. Other types of therapies have also been developed, such as vaccines and gene therapies. Despite these new techniques, the main compounds of interest remain the antibodies anti-TNF-α and anti-CD20, with novelties regarding preparation methods and combination targets. | |
28758827 | Lymphoproliferative disorders in patients with rheumatoid arthritis in the era of widespre | 2018 Jan | Lymphoproliferative disorders (LPD) in patients receiving methotrexate (MTX) have gained strong attention. In this article, I reviewed the basic and clinical findings of this issue. Patients with RA possess a high risk of lymphoma, but epidemiological evidence showing an association between the use of MTX and lymphoma is still limited. Rapid regression of LPD after stopping MTX in patients with RA strongly suggests that there is a causative relationship. Genetic predisposition, accumulated inflammation, impaired generation of Epstein-Barr virus (EBV)-specific cytotoxic T lymphocytes, effects of MTX on the regulation of EBV genes, and low hypermethylation of apoptosis-related genes are relevant to the development of LPD and rapid regression after cessation of MTX. The clinical and histological characteristics of LPD in RA patients who are treated with MTX have been established, and recent data indicate that initial cessation of MTX and watchful waiting to observe an increase in peripheral lymphocyte counts have a therapeutic value. In advanced cases, various chemotherapy regimens are used, and consultation with hematologists is recommended to select the optimal treatment. There is no consensus on the treatment of RA after development of LPD, and long-term observation is necessary to investigate the safety of disease-modifying antirheumatic drugs in these patients. | |
30062629 | Influence of disease-modifying antirheumatic drugs on oxidative and nitrosative stress in | 2018 Oct | BACKGROUND: Nitro-oxidative stress plays a central role in the pathogenesis of rheumatoid arthritis (RA) and several articles show correlation with disease activity. However, the influence and mechanisms by which disease-modifying antirheumatic drugs (DMARDs) may interfere with nitro-oxidative stress are poorly understood. OBJECTIVE: To show the available data on the effect of the DMARDs on the nitro-oxidative stress in RA patients. METHODS: A bibliographic search was carried out in the electronic databases PUBMED, Lilacs, Scientific Electronic Library Online (SCIELO), and Science Direct and the research was limited to human studies, independently of the publication date. RESULTS: Most studies were performed with infliximab (IFX, 4 articles), tocilizumab (TCZ, 3 articles) and methotrexate (MTX, 2 articles). MTX and leflunomide showed similar results with reduction of nitric oxide. The studies with TCZ verified a marked decrease of reactive oxygen and nitrogen species. Most studies with IFX found a reduction of protein oxidation, evaluated by protein carbonyl measurement. In the present review, the most remarkable results were observed with the increase of the antioxidant defenses through several markers and antioxidant systems. The only study with etanercept showed very similar results to those obtained with MTX, with decreased pentosidine and oxidative DNA damage. CONCLUSIONS: The majority of the studies reported in this work showed an improvement in the redox state, which could be related to success of the therapy. Thus, oxidative and nitrosative stress markers may be useful to early evaluate the response of DMARDs in patients with RA. | |
29600931 | Effects of biologic disease-modifying anti-rheumatic drugs on the radiographic progression | 2018 Jul | OBJECTIVES: To evaluate the effect of biologic disease-modifying anti-rheumatic drugs (bDMARDs) on radiographic progression in patients with rheumatoid arthritis (RA). METHODS: A systematic review of electronic databases and conference proceedings was conducted through January 2015, to identify randomised controlled trials (RCTs) and observational studies that assessed the impact of bDMARDs [± conventional synthetic DMARDs (csDMARDs), mainly methotrexate (MTX)], versus csDMARDs alone, on radiographic progression in patients with RA. RESULTS: Following screening of >5000 records, 104 publications covering 63 studies were included. Of 34 RCTs in patients with early, active (n=13) or established RA (n=21) [abatacept (1, 2); adalimumab (4, 2); certolizumab pegol (1, 4); etanercept (3, 3); golimumab (1, 4); infliximab (1, 1); rituximab (1, 1); tocilizumab (1, 5)], combination therapy with a bDMARD and MTX had a significantly greater effect than placebo or MTX alone, in inhibiting radiographic progression. This included patients previously unresponsive, or who responded incompletely, to MTX treatment alone, and was supported by data from observational studies. Findings from a smaller subset of these and other RCTs supported superiority of combination therapy over bDMARD monotherapy, and bDMARD monotherapy over MTX, in slowing radiographic progression. CONCLUSIONS: There is evidence from RCTs with a range of bDMARDs that improvement in radiographic outcomes for patients with early or established RA, when used in combination with MTX and to a lesser extent as monotherapy, are significantly greater than MTX alone. There was no evidence of a difference between bDMARDs on inhibition of radiographic progression. | |
29667454 | Prediction of response to methotrexate in rheumatoid arthritis. | 2018 May | Methotrexate (MTX) is the first-line disease-modifying drug of choice in controlling active inflammation of the synovium that characterises rheumatoid arthritis, a chronic autoimmune inflammatory condition. However, many patients do not respond to treatment with MTX or cannot tolerate the medication. Pre-treatment characteristics that predict response to MTX are, therefore, of particular interest and potential clinical utility. Areas covered: This narrative review seeks to cover various genotypic and phenotypic characteristics that have been investigated as predictors of treatment response to MTX in RA. Ovid Medline searches (1946 to January 2018) were carried out for 'methotrexate' and 'rheumatoid arthritis', in combination with relevant terms. All papers identified were English language, with abstracts. Relevant references were also reviewed. Expert commentary: Despite the introduction of biologic medication and targeted therapies, MTX is likely to remain the mainstay of RA treatment, largely due to its much cheaper cost. Development of a multifactorial predictive algorithm for response to MTX may be of clinical utility, as well as routine MTX drug level testing to improve medication adherence and persistence. | |
29334721 | Efficacy and safety of tocilizumab in Korean patients with active rheumatoid arthritis. | 2019 Jul | BACKGROUND/AIMS: To investigate the efficacy and safety of tocilizumab (TCZ) humanized anti-interleukin-6 receptor monoclonal antibody, in Korean patients with active rheumatoid arthritis (RA) refractory to conventional disease modifying anti-rheumatic drugs (DMARDs) including methotrexate (MTX). METHODS: The main study was a 24-week, randomized, double-blind, controlled trial that was followed by a 48-week, open-labeled, extension phase. TCZ (8 mg/kg) or placebo was intravenously administered every 4 weeks. RESULTS: Those treated with TCZ showed more favorable outcomes in terms of 20% according to the American College of Rheumatology response criteria (ACR20) and ACR50 responses, individual parameters of ACR core set, disease activity score in 28 joints (DAS28) remission, and European League Against Rheumatism (EULAR) response at week 24. These improvements were maintained or increased during the extension period. DAS28 remission at week 72 was associated with EULAR good response at week 12. The patients who experienced any adverse event (AE) were more frequent in the TCZ group compared to the placebo group. Most AEs were mild or moderate in intensity, although TCZ therapy had possible AEs including serious infection, abnormal liver function, and atherogenic lipid profile. CONCLUSION: TCZ infusion add-on is highly efficacious and well-tolerated in Korean patients with active RA refractory to conventional DMARDs including MTX. EULAR good response at week 12 could predict DAS28 remission at week 72. | |
30337216 | Serum free amino acid levels in rheumatoid arthritis according to therapy and physical dis | 2019 Jan | BACKGROUND: In presented study the amino acid analysis was performed in serum derived from rheumatoid arthritis patients (RA) according to undertaken therapy and classification of physical disability. The results were compared with previously published data. METHODS: The levels of 31 free amino acids were determined in 50 serum samples derived from RA subjects and 51 controls. The RA patients were divided into two groups according to the therapy (methotrexate/leflunomide, infliximab/adalimumab/etanercept/tocilizumab, prednisolone/NSAID) and classification of physical disability of the patients. Levels of amino acids were measured by LC-MS/MS. The obtained results were subjected to multivariate statistical tests. RESULTS: According to the therapy that was being used, threonine differentiated RA patients treated with methotrexate/leflunomide - infliximab/adalimumab/etanercept/tocilizumab (p = 0.00954) and infliximab/adalimumab/etanercept/tocilizumab - prednisolone/NSAID (p = 0.03109), while tryptophan differentiated RA patients treated with methotrexate/leflunomide - infliximab/adalimumab/etanercept/tocilizumab (p = 0.01723). In the functional classification, arginine differentiated RA samples between class III and IV (p = 0.02332), while glycine differentiated them between class I+II and III of the Steinbrocker functional classification (p = 0.03366). CONCLUSIONS: An analysis of the metabolome profile requires the use of validated bioanalytical methods that are strictly dedicated for this purpose. The obtained results are not accidental (p value less than 0.05), and all of the selected amino acids play an important role in inflammation and immune response. It is suggested that studied amino acids can be considered as a markers for diagnosis of RA and monitoring pharmacotherapy of the disease. | |
29722740 | Rheumatoid Meningitis: A Case Review. | 2018 May | INTRODUCTION: Rheumatoid meningitis (RM) is a rare complication of rheumatoid arthritis (RA) and has a high mortality rate. It can present as a first diagnosis of RA, in long-standing disease, or in active or well-controlled disease. Neurological manifestations vary widely. CASE REPORT: A patient with a 30-year history of RA, well controlled with methotrexate therapy, presented with new-onset seizures. Magnetic resonance imaging showed leptomeningeal and pachymeningeal enhancement. A de novo workup resulted in diagnosis of RM. CONCLUSIONS: Cerebrospinal fluid findings for RM are nonspecific, typically lymphocytic pleocytosis; however, they can be neutrophilic, as in this case. Magnetic resonance imaging findings consist of leptomeningeal and pachymeningeal enhancement but can also involve the parenchyma. The diagnosis is typically confirmed with meningeal biopsy. Treatment involves high-dose corticosteroids or immunomodulatory therapy, or both. Long-term follow-up with radiologic surveillance typically ranges from improvement to resolution. | |
30558013 | Recognition of gout in rheumatoid arthritis: A case report. | 2018 Dec | RATIONALE: Rheumatoid arthritis (RA) and gout are common rheumatic diseases. However, their coexistance has been rarely reported. Here in, we describe a case of a middle aged Chinese woman having RA complicated with atypical gout on both the knee joints. PATIENT CONCERNS: A 44-year-old Chinese woman complained of swelling and tenderness of multiple joints since 10 months. She had a positive rheumatoid factor and high titers of anti-CCP antibody. She was diagnosed with RA, and commenced on methotrexate, leflunomide, and methylprednisolone. Her symptoms of pain and swelling over interphalangeal and wrists joints subsided except the knee joints. She was started with treat to target treatment (TTT) for RA and rest of her medications was adjusted accordingly. Surprisingly, her symptoms did not improve ever after the addition of a biologic agent, tumor necrosis factor (TNF)-α receptor antagonist. DIAGNOSIS: Presence of urate crystals in the synovium was viewed under polarization microscope which was extracted from one of the knee joint. Hence, we established the diagnosis of RA complicated with gout. INTERVENTIONS: We commenced her on TNF-α receptor antagonist, colchicines, and febuxostat. OUTCOMES: Her symptoms of pain and swelling improved significantly on both the knees and no longer recurred. LESSONS: Coexistence of RA and gout has been rarely reported as it is not frequently seen in clinical practice. Hence, when patients with RA with oligoarthritis repeatedly do not respond to TTT, a standard antirheumatism treatment, the possibility of RA complicating with gout should be rule out. | |
27126059 | Effect of early treatment on physical function in daily management of rheumatoid arthritis | 2018 Apr | AIM: The purpose of this study was to assess 5-year changes in physical function and factors associated with improvement among patients with rheumatoid arthritis (RA) in daily clinical practice, focusing on the effect of treatments, including biologic agents, in the early stage of disease course. METHODS: The National Database of Rheumatic Diseases by iR-net in Japan (NinJa) was searched for patients with disease duration ≤ 2 years and modified health assessment questionnaire (mHAQ) > 0 between 2004 and 2007, so that 510 patients were included in the final analysis. Multivariate-logistic regression analyses were used to identify predictors of 5-year mHAQ disability score improvement. RESULTS: Median mHAQ score was 0.40 at baseline and decreased to a median 0.17 after 5 years. Seventy-four percent of the patients were treated with methotrexate (MTX) and 25% with biologic agents, with early use of biologic agents (within 2 years of RA onset) increasing over time. Multivariate analyses identified higher baseline Disease Activity Score of 28 joints - C-reactive protein and early use of MTX (within 1 year of RA onset) and of biologic agents (within 2 years) as significantly associated with improved mHAQ; odds ratios of the early treatment were 1.83 (P = 0.01) for MTX and 2.23 (P = 0.04) for biologic agents, respectively. CONCLUSION: Five-year mHAQ improved in early RA patients in the NinJa database. In daily clinical management of RA, likewise in clinical trials, early administration of MTX or biologic agents is able to improve physical function outcome. | |
30511295 | MicroRNA-132, miR-146a, and miR-155 as potential biomarkers of methotrexate response in pa | 2019 Mar | INTRODUCTION: Rheumatoid arthritis (RA) patients have high expression levels of hsa-miR-132-3p, hsa-miR-146a-5p, and hsa-miR-155-5p in peripheral blood. We studied if baseline blood levels of these microRNAs (miRNAs) could predict response to methotrexate (MTX). METHODS: RA patients (the American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) criteria) with active disease (disease-modifying anti-rheumatic drug (DMARD)-naïve and Disease Activity Score 28 (DAS28) > 3.2) were enrolled. They were treated with MTX by gradually increasing dose up to 25 mg/week. After 4 months, the DAS28 score was calculated and EULAR response was assessed. The hsa-miR-132-3p, hsa-miR-146a-5p, and hsa-miR-155-5p levels were measured by real-time qPCR in whole-blood RNA at baseline and 4 months after therapy, using hsa-let-7a-5p as housekeeping gene. Results are expressed as median (interquartile range). RESULTS: The 94 enrolled patients (81 females) had a median age of 40 (17) years, disease duration of (24) months, and DAS28 4.61 (1.11). After 4 months of therapy, 73 were classified as responders and 21 as non-responders. Baseline levels of all three miRNAs were lower in responders than non-responders, hsa-miR-132-3p (- 8.03 (0.70) versus - 7.47 (0.85), P < 0.05), hsa-miR-146a-5p (- 5.11 (0.88) versus - 4.62 (0.90), P < 0.05), and hsa-miR-155-5p (- 7.59 (1.07) versus - 7 (0.72), P = 0.002). Receiver operating characteristic curve analysis showed that all three miRNAs were also good predictors of MTX response, showing the following values: hsa-miR-132-3p (area under curve (AUC) 0.756, P < 0.05), hsa-miR-146a-5p (AUC 0.760, P < 0.05), and hsa-miR-155-5p (AUC 0.728, P = 0.002). CONCLUSION: hsa-miR-132-3p, hsa-miR-146a-5p, and hsa-miR-155-5p are potential biomarkers of responsiveness to MTX therapy. | |
30408585 | Arthritis in primary Sjögren's syndrome: Characteristics, outcome and treatment from Fren | 2019 Jan | OBJECTIVE: To describe the characteristics and the outcome of primary Sjögren Syndrome (pSS) associated arthritis and to compare the efficacy of different therapeutic regimen. METHODS: We conducted a retrospective study using Club Rhumatisme and Inflammation (CRI) and French Internal Medicine Society (SNFMI) networks. All patients with a diagnosis of pSS and at least one episode of clinical and/or echographic synovitis were included. Patients with synovitis (cases) were compared to pSS patients without synovitis (controls). RESULTS: 57 patients (93% women) were included with a median age of 54 years [45-63]. Patients with synovitis had more frequently lymph node enlargement (12.3% vs. 1.8%, p = .007) and a higher ESSDAI score (8 [6-12] vs. 2 [1-4], p < .0001). There was no difference concerning CRP levels, rheumatoid factor and cyclic citrullinated peptide (CCP)-antibodies positivity. Among 57 patients with synovitis, 101 various treatment courses have been used during the follow-up of 40 [22.5-77] months. First treatment course consisted in steroids alone (3.5%), steroids in association (79%) with hydroxychloroquine (HCQ) (49%), methotrexate (MTX) (35%), rituximab (RTX) (5.3%) or other immunosuppressive drugs (7%). HCQ, MTX, and RTX were associated with a significant reduction of tender and swollen joint count, and a significant steroids-sparing effect. No difference could be shown for the joint response between these treatment regimens. CONCLUSION: pSS articular manifestations may include synovitis which could mimic rheumatoid arthritis but differ by the absence of structural damage. Even if the use of HCQ, MTX, and RTX seem to be effective for joint involvement, the best regimen remains to be determined. | |
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. | |
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. | |
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. | |
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. |
