27683140 Serological markers associated with disease activity in patients with rheumatoid arthritis 2016 Sep OBJECTIVE: To evaluate prospectively serological markers at baseline and during treatment in patients with rheumatoid arthritis (RA) initiating rituximab treatment, following failure of antitumour necrosis factor (TNF)-α therapy. METHODS: Patients with RA and healthy control subjects were recruited. Plasma complement (C)3, C4, rheumatoid factor (RF), anticitrullinated protein antibody (ACPA), immunoglobulin (Ig)M, A and G, disease activity scores (DAS) and therapeutic response were recorded at baseline and at 6, 12 and 18 months. RESULTS: Patients (n = 35) had significantly higher C3 and C4 levels than controls (n = 30). At 12 months after initiation of rituximab, C3 and C4 levels were significantly lower in patients who responded to treatment, compared with nonresponders. There were direct correlations between C3 levels and DAS at 12 months in the study population as a whole, and between IgM levels and DAS in responding patients after 6, 12 and 18 months' treatment. CONCLUSIONS: C3 and IgM levels may represent potentially useful serological markers of disease activity during rituximab treatment in patients with RA.
27964793 Lung involvement in inflammatory rheumatic diseases. 2016 Oct This chapter describes the involvement of the lung in systemic inflammatory joint disease (IJD) with a particular focus on rheumatoid arthritis, although the topics of pulmonary involvement in ankylosing spondylitis and psoriatic arthritis are also addressed. Interstitial lung disease is the most lethal pulmonary complication of IJD and the chapter describes recent advances in both our understanding of this complication and the therapeutic options that offer real hope for improved outcomes. Although less well recognised, airways disease is just as common and its association with IJD is described in some detail, with a section devoted to the recent surge in interest in bronchiectasis. Acute pulmonary infection is common in IJD and its management is reviewed in some detail. Although pleural disease is less common than it once was, its treatment is explored. We conclude by reviewing the relationship between the drug therapies employed in IJD and their effects on the lung.
26366085 Efficacy of biological agents administered as monotherapy in rheumatoid arthritis: a Bayes 2015 BACKGROUND: Biological agents provide an important therapeutic alternative for rheumatoid arthritis patients refractory to conventional disease-modifying antirheumatic drugs. Few head-to-head comparative trials are available. PURPOSE: The aim of this meta-analysis was to compare the relative efficacy of different biologic agents indicated for use as monotherapy in rheumatoid arthritis. METHODS: A systemic literature search was performed on electronic databases to identify articles reporting double-blind randomized controlled trials investigating the efficacy of biologic agents indicated for monotherapy. Efficacy was assessed using American College of Rheumatology (ACR) 20, 50, and 70 criteria at 16-24 weeks. Relative efficacy was estimated using Bayesian mixed-treatment comparison models. Outcome measures were expressed as odds ratio and 95% credible intervals. RESULTS: Ten randomized controlled trials were selected for data extraction and analysis. Mixed-treatment comparison analysis revealed that tocilizumab offered 100% probability of being the best treatment for inducing an ACR20 response versus placebo, methotrexate, adalimumab, or etanercept. Likewise, for ACR50 and ACR70 outcome responses, tocilizumab had a 99.8% or 98.7% probability of being the best treatment, respectively, compared to other treatments or placebo. Tocilizumab increased the relative probability of being the best treatment (vs methotrexate) by 3.2-fold (odds ratio: 2.1-3.89) for all ACR outcomes. CONCLUSION: Tocilizumab offered the greatest possibility of obtaining an ACR20, ACR50, and ACR70 outcome vs other monotherapies or placebo.
26236339 An Insight into Methods and Practices in Hip Arthroplasty in Patients with Rheumatoid Arth 2015 Total hip arthroplasty (THA) has improved the quality of life of patients with hip arthritis. Orthopedic community is striving for excellence to improve surgical techniques and postoperative care. Despite these efforts, patients continue facing postoperative complications. In particular, patients with rheumatoid arthritis display a higher risk of certain complications such as dislocation, periprosthetic infection, and shorter prosthesis durability. In this review we present the current knowledge of hip arthroplasty in patients with rheumatoid arthritis with more insight into common practices and interventions directed at enhancing recovery of these patients and current shortfalls.
26251689 A Rare Case of Cardiac Tamponade Induced by Chronic Rheumatoid Arthritis. 2015 Sep Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease primarily involving the joint synovium. RA is a systemic disease which has many known extra-articular manifestations. We present a unique case of a patient with long standing RA who presented with a primary complaint of chest and back pain. Echocardiography revealed borderline normal left ventricular function and a large pericardial effusion with the finding of elevated intrapericardial pressure suspicious for cardiac tamponade. Infectious workup was all found to be negative. The presence and elevation of anti-cyclic citrullinated peptide antibody, rheumatoid factor and C-reactive protein (CRP) confirmed the patient was having an active flare-up of RA. It was determined that this flare-up was the cause of the cardiac tamponade. A pericardiocentesis was performed and 850 mL of bloody fluid was drained. The patient remained stable following the pericardiocentesis. At his follow-up visit, repeat echocardiogram showed no signs for pericardial effusion. Although there has been extensive study of RA, there are only a few documented cases noting the occurrence of cardiac tamponade in these patients. Therefore, it is important for the clinician to be aware of and recognize this potentially serious cardiac outcome associated with a common rheumatologic condition.
27891268 A Case Report Describing a Rare Presentation of Simultaneous Occurrence of MPO-ANCA-Associ 2016 Background. Renal-limited myeloperoxidase vasculitis with simultaneous rheumatoid arthritis is reported as a rare occurrence. Review of literature suggests that most patients had a diagnosis of rheumatoid arthritis for several years prior to presenting with renal failure from myeloperoxidase vasculitis. Case Presentation. A 58-year-old Caucasian male presented to the hospital experiencing malaise, fevers, decreased oral intake, nausea, and vomiting for one week duration. His past medical history consisted of newly diagnosed but untreated rheumatoid arthritis, hypertension, and non-insulin-dependent diabetes mellitus. He was found to have acute renal failure, proteinuria, and hypoglycemia. Standard therapy, including intravenous fluids, did not improve his acute renal failure. A vasculitis workup resulted in a positive myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA). Renal biopsy revealed crescentic glomerulonephritis (GN) pauci-immune type, suggestive of MPO-ANCA-associated vasculitis (MPO-AAV). Treatment consisted of prednisone, cyclophosphamide, and seven cycles of plasmapheresis, in addition to hemodialysis for uremia. Upon discharge, he received hemodialysis for another week and continued treatment with cyclophosphamide and prednisone. Conclusion. Patients with longstanding rheumatoid arthritis may develop renal failure due to nonsteroidal anti-inflammatory medication use and AA type amyloidosis; however, necrotizing glomerulonephritis with crescent formation has been rarely reported. This stresses the importance of early recognition and swift initiation of treatment.
27078243 [Sjögren's syndrome]. 2016 Apr Sjögren's syndrome is a frequent autoimmune disease and is associated with a lymphocytic infiltration of the lachrymal and salivary glands and with sicca symptoms. Its diagnostic procedures consist of the quantification of tear and saliva production, identification of extraglandular manifestations, measurement of antibodies against SS-A and SS-B and of salivary gland biopsies. Dry eyes and dry mouth are treated only symptomatically, whereas extraglandular manifestations are treated similar to systemic lupus erythematosus.
26064129 A Case of Diverticular Perforation in a Young Patient with Rheumatoid Arthritis on Methotr 2015 Background. Disease-modifying antirheumatic drugs (DMARDs), such as methotrexate (MTX), are associated with gastrointestinal toxicity. MTX inhibits dihydrofolate reductase, but it is unclear if polymorphisms of the methylenetetrahydrofolate reductase (MTHFR) gene predict toxicity. Case. We describe a 33-year-old male with polyarticular rheumatoid arthritis who developed sigmoid diverticular perforation while receiving methotrexate, folic acid, prednisone, and naproxen. He tested heterozygous for the C677T allele MTHFR gene. Discussion. Rheumatoid arthritis and its treatments are associated with increased risk of gastrointestinal disease. In one study, perforation was highest among individuals with concomitant exposure to NSAIDs, nonbiologic DMARDs, and glucocorticoids. Multiple mutations of the MTHFR gene have been identified, but their association with MTX toxicity is unclear. This case adds to a growing body of literature that could help inform the treatment of others in the future.
27095672 One year in review 2016: Sjögren's syndrome. 2016 Mar Sjögren's syndrome (SS) is a complex heterogeneous disease charactered by a broad spectrum of clinical and serological manifestations, including non-Hodgkin's lymphoma (NHL). Last year, 2015, was an exciting year for research into SS with novel insights into disease pathogenesis, clinical aspects and long-term outcomes. In addition, the use of biologic therapy in SS is rapidly expanding, with new evidence emerging regarding potential therapeutic targets. In this article, we will provide an overview of the recent literature on the pathogenesis, clinical features and novel treatments of SS.
27847572 Risk Factors for the Development and Progression of Atlantoaxial Subluxation in Surgically 2016 Nov OBJECTIVE: Rheumatoid arthritis (RA) is a systemic disease that can affect the cervical spine, especially the atlantoaxial region. The present study evaluated the risk factors for atlantoaxial subluxation (AAS) development and progression in patients who have undergone surgical treatment. METHODS: We retrospectively analyzed the data of 62 patients with RA and surgically treated AAS between 2002 and 2015. Additionally, we identified 62 patients as controls using propensity score matching of sex and age among 12667 RA patients from a rheumatology registry between 2007 and 2015. We extracted patient data, including sex, age at diagnosis, age at surgery, disease duration, radiographic hand joint changes, and history of methotrexate use, and laboratory data, including presence of rheumatoid factor and the C-reactive protein (CRP) level. RESULTS: The mean patient age at diagnosis was 38.0 years. The mean time interval between RA diagnosis and AAS surgery was 13.6±7.0 years. The risk factors for surgically treated AAS development were the serum CRP level (p=0.005) and radiographic hand joint erosion (p=0.009). The risk factors for AAS progression were a short time interval between RA diagnosis and radiographic hand joint erosion (p<0.001) and young age at RA diagnosis (p=0.04). CONCLUSION: The CRP level at RA diagnosis and a short time interval between RA diagnosis and radiographic hand joint erosion might be risk factors for surgically treated AAS development in RA patients. Additionally, a short time interval between RA diagnosis and radiographic hand joint erosion and young age at RA diagnosis might be risk factors for AAS progression.
27103846 Analysis of Mitogen-Activated Protein Kinases in Bone and Cartilage of Patients with Rheum 2016 The aim of this study was to analyze the histological changes related to mitogen-activated protein (MAP) kinases in bone and cartilage treated with abatacept for rheumatoid arthritis (RA). A total of 20 patients of bone and cartilage were assessed: 10 abatacept with methotrexate (MTX)-treated RA patients were compared with 10 MTX-treated RA patients (control). The histology of bone and cartilage was observed by staining with hematoxylin and eosin and analyzed immunohistochemically for the expression of tumor necrosis factor-α, interleukin-6, CD4 (T cell), CD68 (macrophage), receptor activator of nuclear kappa-B ligand, osteoprotegerin, osteopontin, CD29 (β-1 integrin), phospho-p38 MAPK (Tyr180/Tyr182), phospho-p44/42 MAPK (extracellular signal-regulated kinase, ERK1/ERK2), and phosphor-c-Jun N-terminal kinase. The expressions of CD29 known as mechanoreceptor and ERK known as mechanotransduction signal protein in MAP kinases in the bone and cartilage of patients treated with abatacept were significantly different from those of control. These findings suggest that increases in CD29 and ERK in MAP kinases may change the metabolism of bone and cartilage in RA patients treated with abatacept.
28250722 Acute resistance exercise reduces increased gene expression in muscle atrophy of ovariecto 2016 Dec OBJECTIVE: We studied the effect of resistance exercise (RE) on mRNA levels of atrogin-1, MuRF-1, and myostatin in the gastrocnemius muscle of arthritic rats after loss of ovarian function (LOF). MATERIAL AND METHODS: Thirty female Wistar rats (nine weeks old, 195.3 ±17.4 grams) were randomly allocated into five groups: control group (CT-Sham; n = 6); group with rheumatoid arthritis (RA; n = 6); group with rheumatoid arthritis subjected to RE (RAEX; n = 6); ovariectomy group with rheumatoid arthritis (RAOV; n = 6); and an ovariectomy group with rheumatoid arthritis subjected to RE (RAOVEX; n = 6). After 15 days of intra-articular injections with Met-BSA the animals were subjected to RE and six hours after workout were euthanised. RESULTS: The rheumatoid arthritis provoked reduction in the cross-sectional area (CSA) of muscle fibres, but the CSA was lower in the RAOV when compared to the RA groups. Skeletal muscle atrogin-1 mRNA level was increased in arthritic rats (RA and RAOV), but the atrogin-1 level was higher in RAOV group when compared to other arthritic groups. The Muscle MuRF-1 mRNA level was also increased in the RAOV group. The increased atrogin-1 and MuRF-1 mRNA levels were lower in the RAOVEX group than in the RAOV group. The myostatin mRNA level was similar in all groups, except for the RAOVEX group, in which it was lower than the other groups. CONCLUSIONS: LOF results in increased loss of skeletal muscle-related ubiquitin ligases (atrogin-1 and MuRF-1). However, the RE reduces the atrogin-1, MuRF-1, and myostatin mRNA levels in muscle of arthritic rats affected by LOF.
27010839 In arthritis the Doppler based degree of hypervascularisation shows a positive correlation 2016 Oct OBJECTIVES: Power Doppler ultrasound is used to assess joint vascularity in acute arthritis. PDUS signals have been correlated with synovial histology and bone deterioration. Little is known about the correlation between power Doppler signals and synovial white blood count. In our study, we analyzed power Doppler signals in inflammatory joint diseases including gout, calcium pyrophosphate deposition disease, rheumatoid arthritis, spondyloarthritis and others and correlated power Doppler signals with synovial white blood count and with serologic markers of inflammation. METHODS: We retrospectively evaluated 194 patients with arthritis. All patients underwent joint sonography, power Doppler ultrasound, synovial fluid analysis and blood examination of C-reactive protein and erythrocyte sedimentation rate. Correlation analyses (Spearman and Pearson), Chi(2) test, t-tests, a unifactorial ANOVA and regression analyses were applied. RESULTS AND CONCLUSIONS: Hypervascularisation in power Doppler was most prominent in gout and calcium pyrophosphate deposition disease. Spondyloarthritis and non-inflammatory joint diseases presented with low degrees of hypervascularisation. Mean synovial white blood count did not differ significantly between crystal-related arthritides, rheumatoid arthritis, spondyloarthritis or other inflammatory joint diseases. There was a positive but weak correlation between power Doppler signals and synovial white blood count (P<0.001, rs=0.283), erythrocyte sedimentation rate (P<0.001, rs=0.387) and C-reactive protein (P<0.001, rs=0.373) over all diagnoses. This was especially relevant in rheumatoid arthritis (P<0.01, rs=0.479). Power Doppler degrees 0 and 1 were able to predict synovial leukocytes<5/nL, degrees 2 and 3 predict leukocytes≥5/nL (P<0.001).
26022574 Oral involvement in patients with primary Sjögren's syndrome. Multidisciplinary care by d 2015 Nov Primary Sjögren's syndrome is a chronic systemic autoimmune disease that causes destruction of lacrimal and salivary glands. The most common and earliest symptoms are oral and ocular dryness. Dry mouth makes talking difficult, tasting and chewing properly, impairing quality of life of these patients. The most common oral signs and symptoms are hyposialia with or without xerostomia, tooth decay, fungal infections, traumatic oral lesions, dysphagia, dysgeusia, and inflammation of salivary glands. There are different therapeutic strategies, depending on the severity of each case, and the increase in the amount of saliva, to reduce the number of cavities and oral infections. It is particularly important to establish a close relationship between the dentist and the rheumatologist in order to make an early and correct diagnosis, promoting appropriate dietary and hygiene measures, as well as to treat and prevent potential oral complications.
26684993 Sjögren's Syndrome: Oral Manifestations and Treatment, a Dental Perspective. 2015 Dec PURPOSE: Sjögren's syndrome is a systemic autoimmune disease affecting approximately 3 million Americans, primarily perimenopausal women. The syndrome is characterized by dysfunction and destruction of exocrine glands leading to oral and ocular manifestations, xerostomia and keratitis sicca. Sjögren's syndrome commonly remains either undiagnosed or is diagnosed years after the onset of symptoms. Diagnosis is based on the concurrent presence of various signs and symptoms of the disease as established by 6 diagnostic standards set by the American European Consensus Group standards: oral symptoms, ocular symptoms, evidence of oral signs, evidence of ocular dryness, evidence of salivary gland involvement with positive Anti-Ro/La autoantibodies and a positive gland biopsy. Currently no definitive test or cure exists; treatment is predominately palliative and supportive. CONCLUSION: With an aging population and heavier reliance on medications and treatments which cause xerostomia, oral health professionals are likely to encounter a higher incidence of xerostomia and Sjögren's syndrome more than ever before. The dental professional must recognize the signs and symptoms of xerostomia, include Sjögren's syndrome in their differential diagnosis, and communicate those findings and concerns to other health care providers, including the primary care physician, rheumatologist and ophthalmologist for evaluation in a timely fashion. This article discusses the dental professional's role in formulating a preventive oral health plan: meticulous oral hygiene instructions, dietary counseling, a complement of chemotherapeutic agents and more frequent recall care to avoid oral complications and improve quality of life. Dental hygienists can help patients understand the wide range of products available to substitute or stimulate salivary flow, prevent or remineralize early carious lesions and relieve candidal and bacterial infections. Ultimately this collaboration of care by the dental and medical professionals will benefit the Sjögren's syndrome patient and lead to better patient outcomes.
27822121 The Danish nationwide clinical register for patients with rheumatoid arthritis: DANBIO. 2016 INTRODUCTION: DANBIO is a research register and a data source for rheumatologic diseases (rheumatoid arthritis [RA], axial spondyloarthritis, and psoriatic arthritis) for monitoring clinical quality at the national, regional, and hospital levels. STUDY POPULATION: The register includes patients with rheumatologic diseases who are treated at a hospital or a private rheumatologic clinic. Registration is mandatory for all patients with RA regardless of treatment and also for patients with other diagnoses if treated with biological disease-modifying antirheumatic drugs. Since 2006, the registration has been done electronically, including patient-reported outcome measures registered electronically by the patients with the use of touch screens. MAIN VARIABLES: Core variables such as diagnosis, year of diagnosis, age, and sex are registered at the beginning. Data entered at later visits included the following: patient-reported outcomes for disease activity, pain, fatigue, functional status, and physician-reported objective measures of disease activity, treatment, C-reactive protein, and, when indicated, imaging. For subgroups of patients, the variables such as quality of life, sociodemographic factors, lifestyle, and comorbidity are also registered. DESCRIPTIVE DATA: The DANBIO cohort comprised ∼26,000 patients with RA, 3,200 patients with axial spondyloarthritis, and 6,200 patients with psoriatic arthritis in 2015. DANBIO has high nationwide coverage and completeness on key data variables. More than 60 original papers as well as annual reports of clinical quality (since 2005) have been published. CONCLUSION: DANBIO is a powerful register for research in rheumatologic diseases and furthermore serves as a Clinical Quality Register with the aim of monitoring treatment quality in patients with RA in Denmark.
27616030 Inhibitory effects of Saussurea involucrata (Kar. et Kir.) Sch. -Bip. on adjuvant arthriti 2016 Dec 24 ETHNOPHARMACOLOGICAL RELEVANCE: Saussurea involucrate (Kar. et Kir.) Sch. -Bip is an endangered species of the Compositae family, and this species has long been used for the treatment of rheumatoid arthritis, dysmenorrhea, stomachache, and altitude sickness in Uighur folk and Chinese medicine. AIM OF THE STUDY: This study aimed to investigate the different therapeutic efficacy of alcohol infusion (SEI) and water decoction (SWD) of S. involucrata in treating rheumatoid arthritis using complete Freund's adjuvant (CFA)-induced arthritis (AA) in a rat model. MATERIALS AND METHODS: Male Wistar rats (160-180g) were immunized by intradermal injection of 0.1mL of CFA into the left hind metatarsal footpad. Aspirin was chosen as the positive drug. Alcohol infusion (SEI, 400 and 800mg/kg) and water decoction (SWD, 443 and 886mg/kg) of S. involucrata aerial parts were orally administered from day 1 and continued for 21 days. Arthritis severity was evaluated by arthritic score, body weight loss, and paw swelling. The levels of TNF-α, IL-β, and IL-6 in the serum of AA rats were detected by enzyme linked immunosorbent assay (ELISA). Histological changes in the ankle joint were also analyzed in the AA rats. RESULTS: Both SEI and SWD significantly ameliorated AA severity, as suggested by the modulatory effects on body weight loss, paw swelling, and arthritic score. Histopathological improvement in the joint architecture was also observed in the SEI- and SWD-treated AA rats. The overproduction of TNF-α, IL-1β, and IL-6 was remarkably attenuated in the serum of all treated rats. Furthermore, the therapeutic effect of SWD was more potent than that of SEI in treating rheumatoid arthritis using AA in a rat model, which was reported for the first time. CONCLUSIONS: These results suggested that the extract of S. involucrata significantly attenuated adjuvant arthritis in rats by decreasing the levels of TNF-α, IL-1β, and IL-6 in the serum. S. involucrata has the potential to be regarded as a candidate for the treatment of human arthritis. Moreover, the therapeutic effect of SWD was much better than alcohol infusion, indicting that active constituents are mainly in the water extract, which is helpful for the clinical treatments to choose the appropriate process.
26629181 Isorhamnetin attenuates collagen-induced arthritis via modulating cytokines and oxidative 2015 Inflammation and oxidative stress were involved in the development and progression of rheumatoid arthritis (RA). Isorhamnetin has anti-inflammatory and anti-oxidative activities, but its effects on RA have not been investigated. In order to observe the possible therapeutic effects of isorhamnetin on RA, we established a collagen-induced arthritis mouse model and treated the animal with isorhamnetin for 3 weeks. Besides, fibroblast-like synoviocytes (FLS) were treated with lipopolysaccharide (LPS) and isorhamnetin. The severity of arthritis was assessed by arthritis score, joint destruction score and inflammation score. Levels of cytokines TNF-α, IL-1β, IL-6, IL-17A, IL-17F, IL-10 and IL-35 in the joint tissue homogenate and cell culture medium as well as anti-type II collagen antibody in serum were measured using ELISA. Contents of H2O2 and malondialdehyde (MDA) in joint tissue homogenate were measured using assay kits. We found collagen immunization induced significant arthritis in mice and isorhamnetin at the dose of 10 and 20 mg/kg/day could significantly attenuate the collagen-induced arthritis. Isorhamnetin also modulated the production of cytokines and suppressed the oxidative stress in the mice with collagen-induced arthritis at the dose of 10 and 20 mg/kg/day. These data suggested that isorhamnetin might be a potential agent for the management of RA.
27629582 Infections as a cause of autoimmune rheumatic diseases. 2016 Dec Exogenous and endogenous environmental exposures and particularly infections may participate in the breakage of tolerance and the induction of autoimmunity in rheumatic diseases. Response to infections apparently occurs years before clinical manifestations and features of autoimmunity, such as autoantibodies, are detected years before clinical manifestations in autoimmune rheumatic diseases. In this review, we summarize the current evidence for a potential causal link between infectious agents and rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, Sjogren's syndrome and ANCA-associated vasculitis.
27964792 Cardiovascular disease in inflammatory rheumatic diseases. 2016 Oct Chronic inflammatory rheumatic diseases (IRD), including rheumatoid arthritis, ankylosing spondylitis, and psoriatic arthritis, are prevalent conditions worldwide, with a considerable burden on healthcare systems. They are associated with increased cardiovascular (CV) morbidity and mortality. In this review, we focused on the epidemiology, traditional CV risk factors, genetics, and the link between chronic inflammation, atherosclerosis, and CV disease. Remarkably, patients with IRD have higher vulnerability to atheromatous plaques. The risk of unstable plaques is higher in patients with rheumatoid arthritis than in controls. Active disease is a characteristic ascribed to vulnerability and rupture of plaques and a cause of thrombosis in IRD. Management of CV risk in patients with IRD includes optimal control of disease activity. CV risk stratification by applying risk charts is also essential. Imaging techniques might be useful to determine the actual CV risk of patients with IRD who are included in the category of intermediate or moderate CV risk.
