18171484 Does gamma-aminobutyric acid (GABA) influence the development of chronic inflammation in r 2008 Jan 3 BACKGROUND: Recent studies have demonstrated a role for spinal p38 MAP kinase (MAPK) in the development of chronic inflammation and peripheral arthritis and a role for GABA in the inhibition of p38 MAPK mediated effects. Integrating these data suggests that GABA may play a role in downregulating mechanisms that lead to the production of proinflammatory agents such as interleukin-1, interleukin-6, and matrix metalloproteinase 3 - agents implicated in the pathogenesis of rheumatoid arthritis (RA). Genetic studies have also associated RA with members of the p38 MAPK pathway. HYPOTHESIS: We propose a hypothesis for an inefficient GABA signaling system that results in unchecked proinflammatory cytokine production via the p38 MAPK pathway. This model also supports the need for increasing research in the integration of immunology and neuroscience.
17020493 T cell costimulation: a rational target in the therapeutic armamentarium for autoimmune di 2007 T cells are central mediators of adaptive immunity. As such, they are involved in both normal immune responses (e.g., rejection of a transplanted organ) and abnormal ones (e.g., rheumatoid arthritis). T cells require both antigen-specific and costimulatory signals for their full activation. Advances in protein engineering and an increased understanding of the immune response have culminated in the evolution and creation of protein therapeutics that target specific costimulatory molecules. The selective costimulation modulator abatacept (CTLA-4Ig) binds to CD80 and CD86, blocking interaction with CD28, and is approved for the treatment of moderate to severe rheumatoid arthritis. Belatacept, currently enrolling phase III trials in renal transplantation, was rationally designed from abatacept to bind with more avidity to CD86, providing the more potent immunosuppressive properties required for immunosuppression in transplantation. This review describes the relevant immunology and summarizes recent clinical findings on these two molecules. Although both inhibit the CD28 costimulatory pathway, they are tailored for specific disease states--abatacept for autoimmune diseases and belatacept for transplantation.
16981976 Paraneoplastic syndrome, infection or arthritis: Difficulties in diagnosis. 2006 Oct Many different diseases have overlapping clinical symptoms. A major challenge in daily clinical practice is to differentiate between diseases associated with systemic inflammation, such as neoplasia, infection and autoimmune disease. We report on a 46-year-old Caucasian male with a 3-month history of rheumatoid arthritis presenting with dramatic weight loss and dysphagia. Computer tomography revealed multiple lesions in the liver and the spleen, strongly suggesting malignant disease of unknown origin. Surprisingly, on biopsy, the liver lesions drained pus. Workup revealed that the abscesses resulted from gastric perforation, which was the consequence of NSAR therapy for rheumatoid arthritis. Antibiotic therapy was initiated, abscesses diminished and dysfunctional deglutition improved. This unique case demonstrates in a dramatic way the difficulties in daily clinical practice to differentiate between paraneoplasia, infection and autoimmune disease and the potentially life-threatening consequences of their therapy.
19029133 Lactoferrin is a survival factor for neutrophils in rheumatoid synovial fluid. 2009 Jan OBJECTIVES: Lactoferrin is an iron-binding protein that is released from activated neutrophils at sites of inflammation and has anti-microbial as well as anti-inflammatory properties. This study set out to determine whether lactoferrin can delay neutrophil apoptosis and could act as a survival factor for neutrophils in SF. METHODS: Human peripheral blood and SF neutrophils were incubated with iron-free lactoferrin and apoptosis determined after 9 h. SF from patients with RA was added to isolated neutrophils, with or without immunodepletion of lactoferrin, and effects on neutrophil apoptosis determined. Levels of lactoferrin in SF were assessed and related to disease duration and markers of disease activity. RESULTS: Iron-free lactoferrin significantly delayed apoptosis of peripheral blood neutrophils, in a concentration-dependent manner after 9 h in culture (P < 0.04). Lactoferrin could also delay apoptosis of neutrophils isolated from SF of patients with RA. SF from patients with established RA delayed apoptosis of peripheral blood neutrophils and this effect was significantly reduced by depletion of lactoferrin (P < 0.03). Lactoferrin levels in SF from patients with established RA did not correlate with disease severity, but did correlate with markers of inflammation (CRP) and with the presence of RF. SF from patients with arthritis of <12 weeks duration did not contain significant levels of lactoferrin. CONCLUSION: Lactoferrin contributes to extended neutrophil survival in the rheumatoid joint in the established phase of RA but not in very early arthritis.
16620398 Survival of TNF antagonists in spondylarthritis is better than in rheumatoid arthritis. Da 2006 The aim of the present work is to compare drug survival and safety of infliximab, etanercept, and adalimumab (tumor necrosis factor [TNF] antagonists) in spondylarthritis (SpA) with those of rheumatoid arthritis (RA). To this purpose, we analysed the data in BIOBADASER (2000-2005), a drug registry launched in 2000 for long-term follow-up of the safety of these biologics in rheumatic diseases. The rates of drug discontinuation and adverse events (AEs) in SpA (n = 1,524) were estimated and compared with those of RA (n = 4,006). Cox regression analyses were used to adjust for independent factors. Total exposure to TNF antagonists for SpA was 2,430 patient-years and 7,865 for RA. Drug survival in SpA was significantly greater than in RA at 1, 2, and 3 years. The hazard ratio (HR) for discontinuation in SpA compared with RA was 0.66 (95% confidence interval [CI], 0.57-0.76) after adjustment for age, gender, and use of infliximab. The difference remained after controlling for the individual medication and its place in the sequence of treatment. There were fewer SpA patients with AEs (17%) than RA patients (26%; p < 0.001). The HR for AEs in SpA was 0.80 (95% CI, 0.70-0.91) compared with RA after adjustment for age, disease duration, and use of infliximab. In conclusion, due in part to a better safety profile, survival of TNF antagonists in SpA is better than in RA. TNF antagonists are at present a safe and effective therapeutic option for long-term treatment of patients with SpA failing to respond to traditional drugs. Because chronic therapy is necessary, continual review of this issue is necessary.
17404479 [Molecular mechanisms of bone destruction in rheumatoid arthritis]. 2007 Apr Osteoclast in the synovium of rheumatoid arthritis (RA) plays an important role for bone destruction of the affected joints. The osteoclast is differentiated from macrophage-like synoviocyte, which is migrated from peripheral blood monocytes. In the RA synovium, receptor activator of NF-kappaB ligand (RANKL) which is expressed by T cells and fibroblast-like synoviocytes (FLS) and macrophage colony-stimulating factor (M-CSF) which is expressed by FLS induce the differentiation into osteoclast from macrophage-like synoviocyte. TNF-alpha, interleukin (IL) -1, IL-6, and IL-17 which are expressed by macrophages, FLS, and/or T cells in the synovium enhance the differentiation and activation of the osteoclast. Thus, such synovial cells contribute osteoclastgenesis and bone destruction.
18609733 B cell-targeted therapy in autoimmune disease: rationale, mechanisms, and clinical applica 2008 Jul B cells play a critical role in the pathogenesis of rheumatoid arthritis (RA) and other autoimmune diseases. Recently, a number of biologic agents that target B cells have been tested as therapies for these conditions. These agents either deplete B cells, by targeting cell-surface antigens such as CD20, or block B cell function, for example by inhibiting the activity of B cell survival factors such as BLyS. Of this group of agents, the first in clinical use has been rituximab, a chimeric monoclonal antibody that depletes B cells by binding to the CD20 cell-surface antigen. Initially introduced as a treatment for non-Hodgkin's lymphoma, rituximab is now approved for the treatment of RA. In this review we explore the rationale behind B cell-targeted therapy, highlight the results of clinical trials with rituximab in RA and other autoimmune diseases, and describe other emerging therapies directed at B cells.
17299449 Functional staging and surgical intervention of the elbow and shoulder joints in a patient 2007 Feb BACKGROUND: A 46-year-old, nonsmoking, nulliparous woman with a 23-year history of rheumatoid arthritis presented with severely destructed right shoulder, right elbow, and right wrist joints, which resulted in a complete loss of working ability. INVESTIGATIONS: Physical examination, X-ray, MRI, ultrasound, functional staging using the Shoulder Pain and Disability Index, the Patient Rated Elbow Evaluation, the Disabilities of the Arm, Shoulder and Hand, and the health-related quality-of-life Short Form 36 questionnaire, determination of the c-reactive protein level, erythrocyte sedimentation rate, Disease Activity Score 28 and the metalloproteinase profile, and histology of removed synovial tissue. DIAGNOSIS: Severe destruction of the right shoulder and elbow (Larsen grade IV) resulting from late-stage seropositive rheumatoid arthritis. MANAGEMENT: Reconstruction of the elbow and ipsilateral shoulder in a two-step procedure: replacement of the elbow joint with a semiconstrained Gschwend-Scheier-Bahler III (GSB III) elbow prosthesis (Zimmer, Inc., Warsaw, IN) followed by replacement of the shoulder with the Promos Modular Shoulder System (Plus Orthopedics AG, Rotkreuz, Switzerland) 1 month later. The patient received 4 weeks of inpatient rehabilitation.
18253972 WITHDRAWN: Dynamic exercise therapy for treating rheumatoid arthritis. 2008 Jan 23 BACKGROUND: Rheumatoid arthritis (RA) is a chronic inflammatory disease affecting the musculoskeletal system. Inflammation of the joints and tendons results in pain, swelling and restricted movement, eventually leading to radiological changes and deformities. Exercise therapy is considered to be an important cornerstone of the treatment of RA in all stages of the disease. OBJECTIVES: To assess the effects of dynamic exercise therapy in improving joint mobility, muscle strength, aerobic capacity and daily functioning in patients with rheumatoid arthritis (RA). In addition, possible unwanted effects such as an increase in pain, disease activity and radiological progression were studied. SEARCH STRATEGY: We searched the Cochrane Musculoskeletal trials register, the Cochrane Controlled trials Register, MEDLINE, EMBASE and SCISEARCH databases up to May 1997 in order to controlled trials on the effect of exercise therapy. SELECTION CRITERIA: Randomized trials on the effect of dynamic exercise therapy in RA patients with an exercise program fulfilling the following criteria: a) intensity level such that heart rates exceeded 60% of maximal heart rate during at least 20 minutes, b) exercise frequency of two sessions per week, and c) duration of intervention of greater than six weeks DATA COLLECTION AND ANALYSIS: Two blinded reviewers independently selected eligible studies, rated the methodological quality and extracted data. MAIN RESULTS: Six out of 30 identified controlled trials met the inclusion criteria. Four of the six included studies fulfilled at least seven out of 10 methodological criteria. Due to heterogeneity in outcome measures, data could not be pooled. The results suggest that dynamic exercise therapy is effective at increasing aerobic capacity and muscle strength. No detrimental effects on disease activity and pain were observed. The effects of dynamic exercise therapy on functional ability and radiological progression are unclear. AUTHORS' CONCLUSIONS: The results suggest that dynamic exercise therapy is effective at increasing aerobic capacity and muscle strength. No detrimental effects on disease activity and pain were observed. The effects of dynamic exercise therapy on functional ability and radiological progression are unclear. Dynamic exercise therapy has a positive effect on physical capacity. Research on the long-term effect of dynamic exercise therapy on radiological progression and functional ability is needed.
17348244 Sicca symptoms in Thai patients with rheumatoid arthritis, systemic lupus erythematosus an 2006 Dec This study was performed to determine the prevalence of ocular and oral sicca symptoms in Thai patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and scleroderma (Scl). The ocular symptoms and sign (the Schirmer's 1 test) and the oral sicca symptoms and sign (the Saxon's test) in each of 50 RA, SLE and Scl patients were compared with their age-matched controls. The correlation between the presence of sicca symptoms and signs with their clinical activity was also determined. Ocular sicca symptoms were found more common in patients with RA (38% vs 18%, p < 0.05), SLE (36% vs 14%, p < 0.05) and Scl (54% vs 16%, p < 0.01), and oral sicca symptoms were found more common in SLE (22% vs 0%, p < 0.01), and Scl (16% vs 4%, p < 0.05) than their controls. However, only RA patients had a significantly higher proportion of positive Schimer-1 test compared with their controls (p < 0.01). There was no strong correlation between sicca symptoms or signs and other clinical or laboratory variables (age, disease duration, disease activity, disease severity, and antibody to Ro and La antigens) in these three groups. In conclusion, sicca symptoms were seen significantly more common in Thai patients with connective tissue diseases, but the symptoms did not show a good correlation with the clinical and laboratory variables.
17444342 Cardiovascular events in systemic lupus erythematosus and rheumatoid arthritis : emerging 2007 Jan The incidence of cardiovascular disease is significantly increased in the two common autoimmune disorders Systemic Lupus Erythematous (SLE) and Rheumatoid Arthritis (RA). Cardiovascular mortality is a major cause of death in these patients. This has been linked to acceleration of the atherosclerotic process in these disorders. Traditional cardiovascular risk factors alone cannot fully explain the accelerated atherogenesis in these disorders. In addition to the systemic inflammation, additional mechanisms have been put forward that are more specific for the pathophysiology of these autoimmune chronic inflammatory disorders. Further, longitudinal studies are required to define optimal preventive strategies for cardiovascular comorbidity in SLE and RA.
18393882 Histone deacetylase inhibitors: new hope for rheumatoid arthritis? 2008 Histone deacetylase (HDAC) inhibitors are a new family of anti-cancer agents currently undergoing clinical investigations for various oncology indications. Their anti-inflammatory activities had been well documented and they appear to be potential therapeutic strategies for various inflammatory diseases. In this review, the anti-inflammatory activities of HDAC inhibitors with emphasis on their potential applications in rheumatoid arthritis (RA) will be summarized. The possible anti-rheumatic mechanisms, including growth arrest in rheumatoid arthritis synovial fibroblasts (RASFs), suppression of pro-inflammatory cytokines or chemokines, anti-angiogenesis as well as protective effects on bone and cartilage destruction will also be discussed. Current literatures strongly imply HDAC inhibitors as innovative anti-rheumatic drug candidates. However, long-term safety is a major concern. Future investigations should focus on identification of molecular anti-rheumatic mechanisms, development of new classes of HDAC inhibitors with better safety and selectivity profiles, combination of HDAC inhibitors with disease modifying anti-rheumatic drugs (DMARDs) and establishment of topical or intra-articular formulations.
16684371 Validation of the International Classification of Functioning, Disability and Health (ICF) 2006 Functioning is recognized as an important study outcome in rheumatoid arthritis (RA). The Comprehensive ICF Core Set for RA is an application of the International Classification of Functioning, Disability and Health (ICF) of the World Health Organisation with the purpose of representing the typical spectrum of functioning of patients with RA. To strengthen the patient perspective, persons with RA were explicitly involved in the validation of the Comprehensive ICF Core Set for RA using qualitative methodology. The objective of the study was twofold: to come forward with a proposal for the most appropriate methodology to validate Comprehensive ICF Core Sets from the patient perspective; and to add evidence to the validation of the Comprehensive ICF Core Set for RA from the perspective of patients. The specific aims were to explore the aspects of functioning and health important to patients with RA using two different focus group approaches (open approach and ICF-based approach) and to examine to what extent these aspects are represented by the current version of the Comprehensive ICF Core Set for RA. The sampling of patients followed the maximum variation strategy. Sample size was determined by saturation. The focus groups were digitally recorded and transcribed verbatim. The meaning condensation procedure was used for the data analysis. After qualitative data analysis, the resulting concepts were linked to ICF categories according to established linking rules. Forty-nine patients participated in ten focus groups (five in each approach). Of the 76 ICF categories contained in the Comprehensive ICF Core Set for RA, 65 were reported by the patients based on the open approach and 71 based on the ICF-based approach. Sixty-six additional categories (open approach, 41; ICF-based approach, 57) that are not covered in the Comprehensive ICF Core Set for RA were raised. The existing version of the Comprehensive ICF Core Set for RA could be confirmed almost entirely by the two different focus group approaches applied. Focus groups are a highly useful qualitative method to validate the Comprehensive ICF Core Set for RA from the patient perspective. The ICF-based approach seems to be the most appropriate technique.
17214584 Role of PGE2 and EP receptors in the pathogenesis of rheumatoid arthritis and as a novel t 2006 Dec Recent progress in understanding the pathogenesis of rheumatoid arthritis (RA) in parallel with elucidation of the functional role of the prostaglandin receptor subfamily has revealed an important regulatory role of PGE2, in addition to its well-known proinflammatory role in the progression of RA. Characteristic features of RA are synovial proliferation and pannus formation, which result in the destruction of cartilage and bone. Pannus tissue is mainly composed of macrophages and fibroblast-like synoviocytes. Both T cell-derived IL-17 and macrophage-derived TNF-alpha seem to play a central role in the progression of proinflammatory cascades in RA. PGE2 is also produced in response to proinflammatory cytokines, which in turn negatively regulates both IL-17 and TNF-alpha expression and TNF/IL-1-induced activation of fibroblast-like synoviocytes through EP2/EP4 receptors, resulting in the modulation of proinflammatory cascades. IL-17- and TNF-activated macrophages differentiate into osteoclasts in the presence of M-CSF and RANKL expressed by fibroblast-like synoviocytes. PGE2 binding to EP4 stimulates osteoclastogenesis through enhancing RANKL expression. At the same time, PGE2 suppresses osteoclastogenesis by inhibiting M-CSF expression of fibroblast-like synoviocytes as well as both IL-17 and IL-17-induced TNF-alpha expression of macrophages. PGE2-EP4 also activates osteoblastogenesis through increasing cbfa1 and osterix, two essential transcription factors required for bone formation. The net effect of PGE2 may direct toward repair of eroding bone through the suppression of inflammation and enhancement of bone remodeling. Here, we discuss a diverse action of PGE2/EP receptors and their important regulatory roles in the pathogenesis of RA, which may lead to a novel therapeutic strategy.
17180729 In SCID mice with transplanted joint tissues from rheumatism patients, a model mice of hum 2007 Feb PURPOSE: We investigated the tissue distribution of a humanized anti-human Fas monoclonal antibody, R-125224, in SCID mice transplanted with synovial tissues from patients with rheumatoid arthritis (SCID-HuRAg mice). The binding kinetics of R-125224 was also determined, using isolated human synovial cells. MATERIALS AND METHODS: Tissue distribution was assessed at 1, 24 and 168 h after intravenous administration of (125)I-R-125224 to SCID-HuRAg mice (0.4 mg/kg). The in vitro binding of (125)I-R-125224 to isolated human synovial cells was investigated. RESULTS: After intravenous administration of (125)I-R-125224 to SCID-HuRAg mice, the radioactivity distributed to various tissues at 1 h. Thereafter, the radioactivity in the tissues gradually decreased except for the transplanted synovial tissues, in which the radioactivity increased in a time-dependent manner, and at 168 h, the tissue/plasma concentration ratio was about 1. The in vitro binding affinity of (125)I-R-125224 to human synovial cells was high with a dissociation constant of 1.32 +/- 0.62 nM and the binding was inhibited by non-labeled R-125224 in a concentration-dependent manner. CONCLUSION: R-125224, a candidate compound for treating rheumatoid arthritis, specifically distributed to the pharmacological target site, human synovium transplanted in SCID mice, with high affinity.
17364080 The use of biological agents in the treatment of rheumatoid arthritis. 2007 Feb Rheumatoid arthritis is a common and potentially devastating condition which did not have good treatment options until recently. Pharmacological treatment should not just comprise antiinflammatory agents and corticosteroids. The current therapeutic approach is to start a disease modifying agent early in the illness to prevent eventual joint damage. Older disease modifying anti-rheumatic drugs (DMARDs) include methotrexate, sulphasalazine and hydroxychloroquine. Newer ones such as leflunomide and cyclosporine are also used. A recent advance in the management of rheumatoid arthritis is the use of biological agents which block certain key molecules involved in the pathogenesis of the illness. They include tumour necrosis factor (TNF)- blocking agents such as infliximab, etanercept and adalimumab, the anti-CD 20 agent rituximab and CTLA-4 Ig abatacept. Other agents which are in development include anti-IL6 tocilizumab, anti-CD22 and anti-lymphostat B. In this review, the efficacy and side effects of these agents, their impact on current clinical practice and future trends are discussed.
16911172 A nurse-led rheumatology clinic's impact on empowering patients with rheumatoid arthritis: 2006 Sep The aim of this study was to describe a nurse-led rheumatology clinic's impact on empowering patients with rheumatoid arthritis (RA). Rheumatoid arthritis is a chronic, inflammatory disease that attacks many joints, causing considerable functional restrictions for patients. Consequently, these patients are dependent on a wide variety of health-care services. A descriptive, qualitative design inspired by phenomenography was chosen. The conceptions were collected through interviews with 16 strategically selected patients with RA. Three descriptive categories comprising eight conceptions emerged: teaching (gaining insight and receiving information), regular review (receiving security, realizing regularity, and achieving accessibility), and attention (getting a holistic assessment, receiving coordinated care, and getting sufficient time). A nurse-led rheumatology clinic can be a source for empowering patients with RA to adopt new stances to alternative actions and achieve a higher level of faith in their own abilities.
17340047 Obesity is independently associated with impaired quality of life in patients with rheumat 2007 Nov Obesity is a modifiable major cause of morbidity and mortality in the general population, but little is known about the association of obesity and quality of life in patients with rheumatoid arthritis (RA). Thus, we set out a study to test the hypothesis that obesity is independently associated with lower quality of life in patients with RA. Three hundred and fifty nine patients with RA underwent an interview, physical exam, and all clinical charts were reviewed. Based on body mass index (BMI), patients were classified as normal (BMI < 25 kg/m(2)), overweight (BMI = 25-29.9 kg/m(2)), and obese (BMI > or = 30 kg/m(2)). Quality of life was quantified with the Medical Outcomes Study Short Form 36 (SF-36). Data obtained included demographic variables, extra-articular disease, comorbidities, presence of X-ray erosions, rheumatoid factor, and depression. The association between obesity and quality of life was examined with the use of multiple lineal regression models. One hundred and seventy-two patients (47.9%) had normal BMI, 126 (35.1%) were overweight, and 61 patients (17%) were obese. Obese patients had lower quality of life (30.8 +/- 18.1) than overweight patients (43.3 +/- 20.1) and patients with normal weight (43.8 +/- 22.2), P < 0.001. The association between obesity and impaired quality of life was confirmed with a linear regression model (Coef = -12.9, P < 0.001) and remained significant after adjustment for age, sex, disease activity, extra-articular disease, comorbidities, X-ray erosions, presence of rheumatoid factor, depression, education, and disease duration (Coef = -5.3, P = 0.039). In conclusion, obesity is independently associated with the impaired quality of life in patients with rheumatoid arthritis.
18799102 Sexual dysfunction in fibromyalgia patients. 2008 Jul OBJECTIVE: To investigate the prevalence of sexual dysfunction in female patients with fibromyalgia (FM), the impact of FM on sexual activity and the factors associated with sexual dysfunction in these patients. METHODS: Thirty-one consecutive women with FM were enrolled; two groups of 20 aged-matched healthy women and 26 patients with rheumatoid arthritis (RA) were used as controls. Demographic features were recorded in all patients. A cross-sectional analysis of pain (100-mm VAS scale), anxiety and depression (as determined by the STAI and Beck Depression Inventory scales, respectively) was performed. Sexual function was assessed by the Changes in Sexual Functioning Questionnaire (CSFQ). RESULTS: FM and RA patients showed a significantly higher rate of sexual dysfunction compared to healthy controls. Sexual dysfunction was more frequent among FM patients (97%) than in RA patients (84%) but without statistical differences. A univariate analysis showed that age (p=0.0002), marital (p=0.036) and work status (p=0.048), pain intensity (p=0.007), level of anxiety (p=0.002), level of depression (p=0.0005), were significantly associated with sexual dysfunction in FM. However, only the intensity of depression was associated with the sexual dysfunction in patients with FM in the multivariate analysis (p=0.012). CONCLUSIONS: Sexual function was very frequently and severely affected in patients with FM and this impairment appeared to be particularly associated with the degree of depression. The recognition of this dysfunction and its inclusion for the multidisciplinary management of FM may contribute to improve quality of life of these patients.
17014013 sE-Selectin expression and A561C polymorphism in relation to rheumatoid arthritis clinical 2006 Oct OBJECTIVE: To investigate the relationship of A561C polymorphism and sE-selectin levels with rheumatoid arthritis (RA) clinical activity. METHODS: In a case-control study, we compared 60 patients with RA and 60 healthy subjects. Patients fulfilled the 1987 American College of Rheumatology criteria. Soluble E-selectin levels were measured from serum samples using the ELISA kit. We investigated E-selectin A561C polymorphism by the restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR) technique. The disease activity was recorded with Spanish Health Assessment Questionnaire Disability Index (HAQ-DI), Spanish Arthritis Impact Measurement Scales (AIMS), and Disease Activity Score (DAS28) scores. A p value < 0.05 was considered significant. RESULTS: Patients with RA showed higher sE-selectin levels than controls (mean 91.7 vs 39 ng/ml; p = 0.002). A positive correlation between sE-selectin and rheumatoid factor (RF), erythrocyte sedimentation rate (ESR), Spanish HAQ-DI, and DAS28 scores was found. The E-selectin polymorphism analysis showed diminished frequency in RA of heterozygous A/C genotype and increased frequency of homozygous wild-type A/A genotype (p = 0.043, OR 1.45; 95% CI 1.125-16.167) versus A/C and A/A genotype in healthy subjects. No significant association between A561C polymorphism and clinical activity was present. CONCLUSION: The sE-selectin, RF, and ESR, in addition to clinical indices, were associated with clinical activity in RA. We highlighted the presence of A/A genotype A561C polymorphism in our patients with RA.
