27407259 | Multiple pulmonary rheumatoid nodules. | 2015 | We present a case of 45-year-old female patient with the diagnosis of seropositive rheumatoid arthritis, who was admitted to our rheumatology department with exacerbation of the disease. The patient's disease activity score (DAS 28) was 6.9. Physical examination revealed changes in the lung auscultation as a rough breathing sound at the middle and lower lobe of the right lung. Chest X-ray revealed multiple nodular densities in both lungs. Lung biopsy was performed for the diagnosis and revealed necrotizing granulomas with central fibrinoid necrosis surrounded by epithelioid cells. Such a histopathological picture is typical for rheumatoid nodules. Finally the patient was treated with rituximab, with significant improvement. | |
25985813 | Brodalumab -an IL-17RA monoclonal antibody for psoriasis and psoriatic arthritis. | 2015 Jun | INTRODUCTION: IL-17 is a growing target for autoimmune and inflammatory diseases. Brodalumab is a fully human anti-IL-17RA monoclonal antibody that has been investigated in a range of disease including psoriasis, psoriatic arthritis, rheumatoid arthritis, inflammatory bowel disease and asthma. AREAS COVERED: This review aims to summarize up-to-date pharmacological properties of brodalumab and the clinical efficacy and safety data presented in clinical trials. The focus of this review will be on psoriasis, psoriatic arthritis and rheumatoid arthritis although we will briefly touch on the other indications in which the drug has been studied as we feel it adds to our understanding of the IL-17 pathway and highlights areas where research is still needed. EXPERT OPINION: Brodalumab has shown good efficacy in psoriasis in small but extended studies with a moderate effect on psoriatic arthritis. Brodalumab studies are clearly negative in rheumatoid arthritis and inflammatory bowel disease. The data are equivocal in asthma; however, further studies in this disease are justifiable. The safety profile of this drug thus far is not worrisome although longer studies in more patients are needed. | |
26464840 | Relationship between Sleep Disorders, Pain and Quality of Life in Patients with Rheumatoid | 2015 | INTRODUCTION: Rheumatoid arthritis as one of the most common autoimmune diseases is known to be one of the leading causes of disability. Sleep disorders have direct influence on patient's life. According to studies, sleep problems are known to have negative impact on well-being and functioning, but the exact nature of relationship between sleep disorders and Rheumatoid arthritis is not completely understood. This study aimed to investigate the relationship between sleep disorders, pain and quality of life in patients with rheumatoid arthritis patients. METHODS: In a descriptive -correlative study, 210 patients with rheumatoid arthritis referred to Tabriz medical university clinics selected by convenience sampling and were assessed by Sleep Disorders Questionnaire (SDQ), Epworth Sleepiness Scale (ESS), SF-36 Quality of Life Questionnaire and Visual Analog Scale (VAS). Data were analyzed using SPSS-13 by descriptive statistics such as frequency, mean (SD) and inferential statistics including Spearman correlation analysis, linear regression, χ(2),t-test and ANOVA. RESULTS: The mean age of participants was 48.41(12.92) years in which most of them (74%) were female. The mean (SD) quality of life was 40.51(22.94), sleepiness 13.14 (5.6) and pain 6.09 (2.14). There was significant negative relationship between some sleep disorders such as (naps, apnea, asphyxia,…) and pain with quality of life but pain severity had more effect on QOL compared to sleep problems. Furthermore, participants had low quality of life with more restriction in physical (mean=34.71) and general health (mean=34.42). CONCLUSION: Sleep problems and pain were associated with poor quality of life in Rheumatoid Arthritis patients. | |
27559285 | Upper cervical instability associated with rheumatoid arthritis: a case report. | 2016 Jul | Rheumatoid arthritis (RA) affects between 1 and 2 million individuals in the United States. Atlantoaxial instability (AAI) has been shown to have 40-85% prevalence among individuals with RA. Despite the high incidence of craniovertebral involvement, overt symptoms of instability are rare. The high risk of AAI and limited symptomology should increase therapist suspicion of potential contraindications and precautions to initiation of therapy for the cervical spine without prior diagnostic imaging. The purpose of this case study is to describe the historical, clinical, and diagnostic imaging complexity of AAI associated with RA, and to illustrate the use of these factors in the clinical reasoning within a patient case. | |
26557382 | Bone and TNF in rheumatoid arthritis: clinical implications. | 2015 | Experimental data have demonstrated that tumour necrosis factor (TNF) plays a significant role in systemic and local bone loss related to rheumatoid arthritis (RA). In clinical studies on patients with RA, treatment with TNF inhibitors was able to arrest systemic bone loss assessed by bone mineral density and bone turnover markers, but there is scarce evidence of a clinically meaningful effect of TNF inhibition in preventing fractures. TNF inhibitors showed a higher efficacy in reducing radiographic progression related to the disease compared to methotrexate in randomised clinical trials. Data from observational studies seem to confirm the effectiveness of anti-TNF therapy in reducing joint damage evolution. | |
27965259 | Standardisation of labial salivary gland histopathology in clinical trials in primary Sjö | 2017 Jul | Labial salivary gland (LSG) biopsy is used in the classification of primary Sjögren's syndrome (PSS) and in patient stratification in clinical trials. It may also function as a biomarker. The acquisition of tissue and histological interpretation is variable and needs to be standardised for use in clinical trials. A modified European League Against Rheumatism consensus guideline development strategy was used. The steering committee of the ad hoc working group identified key outstanding points of variability in LSG acquisition and analysis. A 2-day workshop was held to develop consensus where possible and identify points where further discussion/data was needed. These points were reviewed by a subgroup of experts on PSS histopathology and then circulated via an online survey to 50 stakeholder experts consisting of rheumatologists, histopathologists and oral medicine specialists, to assess level of agreement (0-10 scale) and comments. Criteria for agreement were a mean score ≥6/10 and 75% of respondents scoring ≥6/10. Thirty-nine (78%) experts responded and 16 points met criteria for agreement. These points are focused on tissue requirements, identification of the characteristic focal lymphocytic sialadenitis, calculation of the focus score, identification of germinal centres, assessment of the area of leucocyte infiltration, reporting standards and use of prestudy samples for clinical trials. We provide standardised consensus guidance for the use of labial salivary gland histopathology in the classification of PSS and in clinical trials and identify areas where further research is required to achieve evidence-based consensus. | |
28936386 | Co-stimulation Therapy in Rheumatoid Arthritis: Today and Tomorrow. | 2015 | Abatacept is the only T cell co-stimulation modulator approved thus far for the treatment of moderate-to-severe rheumatoid arthritis (RA) and is licensed for use in patients with an inadequate response to methotrexate (MTX) and/or anti-tumor necrosis factor (anti-TNF) therapy. The upstream mechanism of action of abatacept leads to downstream effects in a variety of cell types associated with the production of autoantibodies and pro-inflammatory cytokines implicated in RA. Accumulating data also suggest effects on other cells involved in the pathogenesis of RA, including regulatory T cells and osteoclasts. Clinical trials have demonstrated that abatacept is an effective and well-tolerated treatment in RA. More recently, evidence from the Assessing Very Early Rheumatoid arthritis Treatment (AVERT) trial showed that complete drug-free remission following treatment with abatacept may be a possibility in some patients with early RA, indicating that the disease course could be altered by early intervention. Equivalent efficacy and onset of action of abatacept and anti-TNF therapy have also been demonstrated in patients with an inadequate response to MTX in the Abatacept versus adaliMumab comParison in bioLogic-naïvE rheumatoid arthritis subjects with background methotrexate (AMPLE) trial. Together, these findings support the use of abatacept in early and established RA. | |
27683145 | Asymmetric dimethylarginine and arterial stiffness in patients with rheumatoid arthritis: | 2016 Sep | OBJECTIVE: To investigate whether levels of asymmetric dimethylarginine (ADMA), as a measure of endothelial dysfunction, are higher in patients with rheumatoid arthritis compared with healthy control subjects. The relationships between ADMA and surrogate measures of arterial stiffness were evaluated. METHODS: Patients with rheumatoid arthritis and healthy control subjects were recruited. ADMA was quantified via enzyme-linked immunosorbent assay. Arterial stiffness was evaluated using pulse wave analysis. RESULTS: There was no significant difference in plasma ADMA concentration between patients with rheumatoid arthritis (n = 30) and healthy controls (n = 30). Aortic augmentation pressure was significantly higher in patients than in controls. C-reactive protein and Health Assessment Questionnaire score were independent predictors of arterial stiffness in patients. There was no relationship between ADMA concentration and aortic augmentation pressure in the study population as a whole. CONCLUSIONS: Arterial stiffness appears to be increased in rheumatoid arthritis and independently associated with systemic inflammation and physical disability. ADMA concentration was not increased in this small group of patients with rheumatoid arthritis compared with healthy controls; nor was it associated with arterial stiffness. | |
24906639 | Impact of the leucocyte immunoglobulin-like receptor A3 (LILRA3) on susceptibility and sub | 2015 Nov | BACKGROUND: Recently, our research group identified the non-deleted (functional) leucocyte immunoglobulin-like receptor A3 (LILRA3) as a new genetic risk for rheumatoid arthritis. OBJECTIVES: To further investigate whether the functional LILRA3 is a new susceptibility factor for other autoimmune diseases-for example, systemic lupus erythematosus (SLE) and primary Sjögren's syndrome (pSS). METHODS: The LILRA3 deletion polymorphism and its tagging single nucleotide polymorphism rs103294 were genotyped for 1099 patients with SLE, 403 patients with pSS and 2169 healthy controls. Association analyses were performed in whole dataset or clinical/serological subsets. The impact of LILRA3 on SLE activity and LILRA3 expression was evaluated. RESULTS: The functional LILRA3 conferred high susceptibility to both SLE (p=3.51×10(-7), OR=2.03) and pSS (p=1.40×10(-3), OR=2.32). It was associated with almost all the clinical/serological features in SLE, especially with leucopenia (p=4.09×10(-7), OR=2.19) and thrombocytopenia (p=1.68×10(-5), OR=1.70). In pSS, functional LILRA3 was specifically associated with leucopenia (p=4.39×10(-4), OR=3.25), anti-Ro/SSA-positive subphenotypes (p=4.54×10(-3), OR=2.34) and anti-La/SSB-positive subphenotypes (p=0.012, OR=2.49). Functional LILRA3 conferred higher disease activity in patients with SLE (p=0.044) and higher LILRA3 expression in both SLE (p=5.57×10(-8)) and pSS (p=1.49×10(-7)) than in controls. CONCLUSIONS: Functional LILRA3 is a new susceptibility factor for SLE and pSS. It highly predisposes to certain phenotypes such as leucopenia and thrombocytopenia in SLE, and may confer increased disease activity in SLE and a higher risk of leucopenia and autoantibody-positive subphenotypes in pSS. | |
27407258 | Indirect costs of rheumatoid arthritis. | 2015 | It is estimated that in Poland about 400,000 persons in general suffer from inflammatory joint diseases, including rheumatoid arthritis (RA). Epidemiological surveys documenting the frequency and disturbance of musculoskeletal disorders in the Polish population are few in number. Most of the estimations are based on epidemiological data from other countries (prevalence of 0.5-1%). According to the data of the National Health Fund in Poland 135,000-157,000 persons in total are treated because of rheumatoid arthritis per year [ICD10 (International Statistical Classification of Diseases and Related Health Problems): M05, M06]. In the case of this group of diseases indirect costs significantly outweigh the direct costs. Indirect costs increase together with activity level of the disease. The cost analysis of productivity loss of RA patients indicates that sickness absenteeism and informal care are the most burdensome. At the national level it amounts in total from 1.2 billion to 2.8 billion PLN per year, depending on the method of analysis. These costs could be significantly reduced through early diagnosis and introduction of effective treatment. | |
25802129 | [Overlap between systemic sclerosis and rheumatoid arthritis: a distinct clinical entity?] | 2015 Mar 4 | INTRODUCTION: Systemic sclerosis (SSc) is an autoimmune disease of the connective tissue characterized by the triad of vascular injury, autoimmunity (cellular and humoral) and tissue fibrosis. It is estimated that musculoskeletal pain is a common complaint of patients with SSc, ranging from 40 to 80%, and mainly in patients with early diffuse disease. Arthritis, clinically observed, may be a feature seen in the presentation of SSc, often leading to early diagnostic errors with rheumatoid arthritis (RA). In the course of the disease, arthritis is observed in 24 to 97% of patients with SSc. OBJECTIVES: To correlate the occurrence or nonoccurrence of arthritis in patients with SSc of the Midwest region of Brazil with possible distinct clinical and laboratory manifestations observed in three groups of patients. To report the frequency of true association between systemic sclerosis and rheumatoid arthritis in patients with clinically and radiologically observed synovitis. METHODS: Sixty-one SSc patients were subsequently assessed every 3 months within 1 year, in order to clinically observe the occurrence of synovitis and its patterns of progression. Patients were divided into 3 groups: 41 patients with SSc without arthritis, 16 SSc patients with arthritis and 4 patients with overlap of SSc and RA. All patients underwent a radiological examination of the hands at the end of the study. RESULTS: Among all patients evaluated, we found a female predominance (98.7%), mean age of 50.94 years, white color (49.2%), limited form of the disease (47.6%), time of diagnosis between 5 to 10 years (47.6%) and duration of the disease of 8.30 years. Among all patients, 14 (22.9%) had positive rheumatoid factor (RF), while among those with positive RF, only 10 patients had arthritis during one-year follow-up. The antibody anticitrulline (anti-CCP) test was performed in 24 patients, being positive in 4 of them (16.7%), with positivity being observed only in patients with SSc/RA overlap. Comparing the clinical manifestations among the groups of patients, there was a higher incidence of gastritis and cardiac valvulopathy in patients with SSc and arthritis, but not in the others. In the group of patients with SSc/RA overlap and in patients with SSc and arthritis a significant reduction in quality of life was observed, measured by HAQ index, especially in patients with arthritis present during clinical evaluation. We found radiographic changes in 42.6% of patients with SSc. However, in patients with synovitis, radiological changes consistent with rheumatoid arthritis were found in 50% of patients. CONCLUSIONS: While the frequency of clinical arthritis observed in patients with systemic sclerosis was 32.8%, the true overlap between of SSc and RA was 6.6% in this study. We also observed the frequency of positive anti-CCP in 20% of patients with arthritis versus no patients with SSc without arthritis. | |
26509055 | What makes psoriatic and rheumatoid arthritis so different? | 2015 | In many ways, it may be easier to highlight what rheumatoid arthritis (RA) and psoriatic arthritis (PsA) have in common. They are both common conditions characterised by a spectrum of features or clinical manifestations in different organ systems that have led many to conclude that they are actually 'disease syndromes'. Furthermore, many of the organ systems that are affected in both conditions are the same: skin, joints, eyes, vasculature and even the immune system. Indeed, some clinicians fail to recognise these two common arthritides as distinct. And yet, while the manifestations may have a superficial similarity, there are significant differences at a number of levels including clinical, anatomical, microscopic and molecular levels. However, these differences may explain certain clinical manifestations of the two diseases, and more importantly, they may explain different responses to specific therapies and potentially different disease outcomes and prognoses. This may be especially relevant as new therapeutic targets are examined that may be specific for RA or PsA. | |
26002450 | Complications Encountered with Total Hip Arthroplasty in Rheumatoid Patients. | 2015 | Rheumatoid arthritis affects around 1% of the global population with a predilection for Western societies. The treatment of the rheumatoid hip has gone through significant changes in recent years. Although osteotomies and synovectomies were previously commonplace, advances in arthroplasty technique and technology has seen these former procedures being performed less commonly. This article tackles some of the key issues with regard to the rheumatoid hip, namely the increased risk and methods of dealing with protrusio acetabuli, the risk of dislocation, infection and rates of aseptic loosening. | |
27042334 | Patient-initiated appointments compared with standard outpatient care for rheumatoid arthr | 2016 | OBJECTIVES: To test the hypothesis that implementing a patient-initiated system of care could improve clinical outcome in rheumatoid arthritis (RA) using disease activity guided management. METHODS: An 18-month controlled blinded end point two-centre study with 131 patients with RA randomised to intervention (n=64) or control (n=67). The intervention group participants were guaranteed appointments to a rheumatologist within 10 working days if they subjectively experienced a flare in disease activity. The control group participants were booked in advance according to guidelines. Independent assessments were performed in the two groups at 0, 3, 6, 12 and 18 months. Outcome measures included: Disease Activity Score 28 (DAS28), a Visual Analogue Scale (satisfaction with care, confidence in care), number of appointments with a rheumatologist. RESULTS: DAS28 decreased. Median satisfaction and confidence in care were >90 mm on Visual Analog Scale. Median number of appointments was 3. There were no significant differences between the groups among these outcomes. Visits in the intervention group more often resulted in change of treatment than in the control group (p<0.001). CONCLUSIONS: Patient-initiated care was neither better nor inferior to traditional care in terms of outcomes analysed. Patient-initiated appointments can safely be used in everyday outpatient care of RA to empower the patient, if disease activity guided management is applied. Further research should investigate if this intervention can target a subgroup of patients and hence also result in released resources. | |
27056576 | Elbow rheumatoid elbow: surgical treatment options. | 2016 Jun | Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by peripheral polyarthritis. The elbow joint is estimated to be involved in 20 to 65Â % of the patients with RA. The development of new pharmacologic agents and the adoption of early therapeutic interventions have translated into milder forms of polyarticular destruction. As a result, the traditional crippled rheumatoid patient has been replaced by rheumatoid patients with higher activity levels, higher expectations, and more demands on any reconstructive procedures performed. When nonoperative treatment is insufficient, surgery may be considered. Arthroscopic synovectomy has become the procedure of choice for rheumatoid patients with uncontrolled symptoms. Patients with more advanced joint destruction can be considered for elbow arthroplasty. Interposition arthroplasty may be considered for patients interested in avoiding the potential complications of elbow arthroplasty. | |
26136606 | Use of spinal manipulation in a rheumatoid patient presenting with acute thoracic pain: a | 2015 Jun | BACKGROUND: There is limited research related to spinal manipulation of uncomplicated thoracic spine pain and even less when pain is associated with comorbid conditions such as rheumatoid arthritis. In the absence of trial evidence, clinical experience and appropriate selection of the type of intervention is important to informing the appropriate management of these cases. CASE PRESENTATION: We present a case of a patient with long standing rheumatoid arthritis who presented with acute thoracic pain. The patient was diagnosed with costovertebral joint dysfunction and a myofascial strain of the surrounding musculature. The patient was unresponsive to treatment involving a generalized manipulative technique; however, improved following the administration of a specific applied manipulation with modified forces. The patient was deemed recovered and discharged with ergonomic and home care recommendations. DISCUSSION: This case demonstrates a clinical situation where there is a paucity of research to guide management, thus clinicians must rely on experience and patient preferences in the selection of an appropriate and safe therapeutic intervention. The case highlights the need to contextualize the apparent contraindication of manipulation in patients with rheumatoid arthritis and calls for further research. Finally the paper advances evidence based decision making that balances the available research, clinical experience, as well as patient preferences. | |
27352977 | BAFF overexpression increases lymphocytic infiltration in Sjögren's target tissue, but on | 2016 Aug | B-cell activating factor (BAFF) levels are increased in rheumatoid arthritis, lupus and primary Sjögren's syndrome (pSS). However, BAFF contribution to pathogenesis is not completely understood. In pSS, immune infiltration of the salivary and lacrimal glands leads to xerostomia and xerophtalmia. Glandular B cell hyperactivation, differentiation into germinal center (GC)-like structures and plasma cell accumulation are histopathological hallmarks that were attributed to increased BAFF. Here, we experimentally tested this hypothesis by overexpressing BAFF in a mouse model of pSS. BAFF overexpression enhanced lymphocytic infiltration and MHCII expression on B cells. Increased BAFF also induced B cell differentiation into GC B cells within the autoimmune target tissue. However, even in these conditions, GC B cells only accounted for <1% of glandular B cells, demonstrating that BAFF is not efficiently promoting ectopic GC formation in pSS and warranting further investigation of therapeutics targeting both BAFF and the related TNF-family member APRIL. | |
25969663 | Adrenal suppression following herbal remedy for rheumatoid arthritis. | 2015 Apr | A patient suffering from rheumatoid arthritis who had extreme adrenal suppression as a result of chronic use of herbal medicines presented with complications of adrenal suppression such as muscle weakness. He also had psychiatric disturbances such as confusion and suicidal tendency. Steroids in the herbal medication were found and hence there exists a need for investigation into their safety and efficacy. | |
26834501 | Impact of tofacitinib on patient outcomes in rheumatoid arthritis - review of clinical stu | 2016 | Rheumatoid arthritis is a chronic, progressive autoimmune disease associated with inflammation and destruction of joints and systemic effects, which result in significant impact on patient's quality of life and function. Tofacitinib was approved for the treatment of rheumatoid arthritis in the USA in 2012 and subsequently in other countries, but not by the European Medicines Agency. The goal of this review was to evaluate the impact of tofacitinib on patient-reported and patient-specific outcomes from prior clinical studies, focusing on quality of life, functionality, pain, global disease assessment, major adverse consequences, and withdrawals. A total of 13 reports representing 11 clinical studies on tofacitinib in rheumatoid arthritis were identified through PubMed and reference lists in meta-analyses and other reviews. Data on improvements in patient-driven composite tools to measure disease activity in rheumatoid arthritis, such as the Health Assessment Questionnaire, served as a major outcome evaluated in this review and were extracted from each study. Additional data extracted from those clinical studies included patient assessment of pain (using a 0-100 mm visual analog scale), patient global assessment of disease (using a 0-100 mm visual analog scale), patient withdrawals, withdrawals due to adverse effects or lack of effect, and risk of serious adverse effects, serious infections, and deaths. Tofacitinib 5 mg bid appears to have a favorable impact on patient outcomes related to efficacy and safety when compared with baseline values and with comparator disease-modifying antirheumatic drugs and placebo. Improvements were seen in the composite and individual measures of disease activity. Serious adverse effects, other adverse consequences, overall withdrawals, and withdrawals due to adverse effects and lack of efficacy are similar or more favorable for tofacitinib versus comparator disease-modifying antirheumatic drugs and placebo. At this point, tofacitinib appears to have an important role in the treatment of rheumatoid arthritis through improvement in these patient outcomes. However, it may require years of additional clinical studies and postmarketing surveillance to fully characterize the benefit-to-risk ratio of tofacitinib in a larger and diverse patient population. | |
