22132737 | Subthreshold mood symptoms in patients with fibromyalgia and rheumatoid arthritis. | 2011 Nov | OBJECTIVES: Although several findings have highlighted the prevalence of Axis I psychiatric disorders in fibromyalgia (FM) and rheumatoid arthritis (RA), very little information is available on the prevalence of subthreshold mood symptoms in these conditions. Therefore, we aimed at comparing the prevalence of subthreshold mood symptoms in rheumatic patients suffering from FM and RA. The hypothesis is that subthreshold mood symptoms are more represented in FM, given the evidence of higher rates of Axis I psychopathology in FM than in RA. METHODS: Sixty patients suffering from FM and 50 from RA, assessed according to the American College of Rheumatology (ACR) criteria, selected in a Rheumatology Department, were included in the study. The subthreshold affective symptoms were assessed by means of the Mood Spectrum-Self Report (MOODS-SR). RESULTS: The results showed that FM patients presented significantly higher scores than RA patients in 'mood depressive', 'cognition depressive' domains and in total depressive component. CONCLUSIONS: The present study demonstrates that subthreshold depressive symptoms are more represented in FM than in RA patients. This fact could play a role in the worse quality of life and in the major perception of pain which characterises FM. | |
21497535 | Association of interleukin-4 receptor gene polymorphisms with rheumatoid arthritis in Egyp | 2012 Jan | OBJECTIVES: The imbalance between proinflammatory and anti-inflammatory cytokines is a feature of rheumatoid arthritis (RA). The role of interleukin-4 (IL-4) and its receptor in the pathogenesis of RA is conflicting. We aim to investigate the role of polymorphisms in the IL-4Rα gene in susceptibility and severity of RA. METHODS: One hundred and seventy-two RA patients and 172 controls were enrolled in the study. Genotyping of IL-4Rα I50V (rs1805010) and IL-4Rα Q576R (rs1801275) was determined by restriction fragment length polymorphism-polymerase chain reaction (PCR-RFLP). RESULTS: IL-4Rα I50V genotype was significantly more frequent in patients with RA than in controls (OR: 1.97, 95% CI: 1-3.7, P: 0.035). Subjects with IL-4Rα V50V genotype were significantly more likely to have erosive arthropathy (OR: 2.6, 95% CI: 1.1-6.1, P: 0.02). The frequencies of IL-4Rα Q576R genotype were significantly decreased in patients with erosive RA compared to patients with nonerosive RA (31.6% versus 48.2%, OR: 2.7, 95% CI: 1-7.7, P: 0.04). CONCLUSION: IL-4Rα polymorphisms were associated with susceptibility to RA and may be helpful in early detection of erosive RA. | |
22072015 | A tool to identify recent or present rheumatoid arthritis flare from both patient and phys | 2012 Jul | INTRODUCTION: There is a lack of consensus about the definition of flare of rheumatoid arthritis (RA) and a measurement tool. OBJECTIVES: To develop a self-administered tool integrating the perspectives of the patient and the rheumatologist, enabling the detection of present or recent-past RA flare. METHODS: The patient perspective was explored by semistructured individual interviews of patients with RA. Two health psychologists conducted a content analysis to extract items best describing flare from the interviews. The physician's perspective was explored through a Delphi exercise conducted among a panel of 13 rheumatologists. A comprehensive list of items produced in the first round was reduced in a four-round Delphi process to select items cited by at least 75% of the respondents. The identified elements were assembled in domains-each converted into a statement-to constitute the final self-administered Flare Assessment in Rheumatoid Arthritis (FLARE) questionnaire. RESULTS: The content of 99 patient interviews was analysed, and 10 domains were identified: joint swelling or pain, night pain, fatigue and different emotional consequences, as well as analgesic intake. The Delphi process for physicians identified eight domains related to objective RA symptoms and drug intake, of which only four were common to domains for patients. Finally, 13 domains were retained in the FLARE questionnaire, formulated as 13 statements with a Likert-scale response modality of six answers ranging from 'absolutely true' to 'completely untrue'. CONCLUSION: Two different methods, for patient and physician perspectives, were used to develop the FLARE self-administered questionnaire, which can identify past or present RA flare. | |
21477956 | Radiographic outcome in Hispanic early rheumatoid arthritis patients treated with conventi | 2011 Aug | OBJECTIVES: To determine rates of incident erosive disease in early rheumatoid arthritis patients, to identify baseline predictors and to evaluate erosion's impact on patient-reported outcomes. METHODS: 82 patients with ≤ 12 months of disease duration, ≥ 3 years of follow-up and conventional treatment were included. Consecutive evaluations assessed swollen and tender joint counts, treatment and comorbidity, acute reactant-phase determinations and patient-reported outcomes. Digitized radiographs of the hands and feet were obtained at baseline and yearly thereafter. RA was defined as erosive when at least one unequivocal cortical bone defect was detected. Descriptive statistics and Cox regression analysis were performed. RESULTS: At baseline, 71 of the patients were ♀, population median (range) age was of 38.7 (16-78.2) years, 58 patients had antibodies and all the patients had active disease and substantial disability. Follow-up cohort was of 299.3 person-years. At last follow-up (49 ± 13.8 months), 28 patients developed erosions. Erosion's location was the feet, in 12 patients. Incident rates of erosive disease at one, two, three and four years were of 8.1, 12.8, 13.8 and 5.6 per 100 person-years, respectively. Higher C-reactive protein (HR: 1.20, 95%CI: 1.04-1.4, p=0.01) and positive antibodies (HR: 5.09, 95%CI: 1.08-23.86, p=0.04) were baseline predictors of incident erosive disease. Erosions had minor impact on patient-reported outcomes. CONCLUSION: Rheumatoid arthritis patients with antibodies and higher C reactive protein at baseline are at risk for incident erosions which appear most frequently at the feet. Up to 1/3 patients conventionally treated develop incident erosions, which minimally impact function. | |
21642910 | Patients with inflammatory arthritis: an opportunity for community nurses. | 2011 Jun | People with Inflammatory joint disease, e.g. rheumatoid arthritis (RA), have traditionally been treated and managed within secondary care on an outpatient basis. This group of patients has varied and complex needs. With increasing emphasis on offering care closer to home, there is an opportunity for nurses based in the community to become more involved in the management and support of these patients. The level of involvement will depend on the resources available locally and will require education and support for the role. Based on recommendations in recent publications and the author's personal experience working in three different rheumatology departments, this article explores the ways in which community nurses can support people with RA in the community and identify sources for further professional development to support and maintain this. | |
21532380 | Rheumatoid meningitis mimicking progressive supranuclear palsy. | 2011 May | INTRODUCTION: Rheumatoid meningitis is an uncommon manifestation of longstanding rheumatoid arthritis and few cases have been described. The clinical presentation is extremely variable as reported in medical literature. CASE REPORT: We report a 71-year-old woman with 15 years of seropositive rheumatoid arthritis who developed neurological complications: cognitive deterioration; hypomimia; limitation on vertical gaze; and axial stiffness, resembling progressive supranuclear palsy and seizures. Brain magnetic resonance imaging showed a diffuse dural plaque on both frontal and temporal lobes exhibiting homogeneous gadolinium enhancement. There was diffuse leptomeningeal enhancement and hyperintense white matter lesions. The final diagnosis made by image-guided biopsy showed rheumatoid pachymeningitis. After the definitive diagnosis, high doses of corticosteroids and immunosuppressive treatment were started. CONCLUSIONS: We emphasize the diagnostic importance of the biopsy in cases of chronic pachymeningitis and stress that diverse entities can cause progressive supranuclear palsy-like phenotypes. | |
22822176 | Development of a quality of patient-health care provider communication scale from the pers | 2013 Jun | OBJECTIVES: To devise a patient-perspective driven measure of the quality of patient-health care provider communication and to evaluate the psychometric properties of this scale in a sample of 150 patients with rheumatoid arthritis. METHODS: Items were developed from interviews with 15 patients with rheumatoid arthritis. Two rheumatologists, a behavioral scientist, and a nurse researcher provided item feedback. Exploratory factor analysis with Oblimin rotation was used to examine the dimensionality of the newly developed Patient-Health Care Provider Communication Scale (PHCPCS). Cronbach's alpha was computed to assess internal consistency. Test-retest reliability was determined using the intraclass correlation coefficient. Construct validity was tested by comparing the PHCPCS with the Perceived Involvement in Care Scale (PICS) using correlation analysis. RESULTS: The PHCPCS measured two dimensions of the quality of patient-health care provider communication [Quality Communication (α = 0.94) and Negative Patient-Health Care Provider Communication (α = 0.73)]. The total PHCPCS score and its Quality Communication Subscale were positively correlated with the total score on the PICS and with the doctor facilitation subscale of the PICS. DISCUSSION: This new measure of the quality of patient-health care provider communication has the potential for use in clinical practice, provider education, and further studies to improve health care to patients with rheumatoid arthritis. | |
20952475 | Prevalence of vitamin D insufficiency/deficiency in rheumatoid arthritis and associations | 2011 Jan | OBJECTIVE: 25-hydroxy-vitamin D (25-OH-D) insufficiency/deficiency is increasingly prevalent and has been associated with many chronic diseases, including rheumatoid arthritis (RA). Our purpose was to define the prevalence and associations of 25-OH-D insufficiency/deficiency in a cohort of US veterans with RA. METHODS: vitamin D status (25-OH-D) was assessed in patients with RA using radioimmunoassay on banked plasma collected at enrollment. Insufficiency was defined as concentrations < 30 ng/ml and deficiency as < 20 ng/ml. Associations of 25-OH-D insufficiency/deficiency with patient characteristics obtained at enrollment were examined using multivariate logistic regression, adjusting for age, sex, season of enrollment, and race. RESULTS: patients (850 men, 76% Caucasian) had a mean (SD) age of 64 (SD 11.3) years. The prevalences of 25-OH-D insufficiency and deficiency were 84% and 43%, respectively. After multivariate adjustment, both insufficiency and deficiency were more common with anti-cyclic citrullinated peptide antibody positivity and non-Caucasian race, and in the absence of vitamin D supplementation. 25-OH-D deficiency, but not insufficiency, was independently associated with higher tender joint counts and highly sensitive C-reactive protein levels. CONCLUSION: in a predominantly elderly, male RA population, 25-OH-D insufficiency was highly prevalent. With the increasing adverse health outcomes associated with hypovitaminosis D, screening and supplementation, particularly among minority, seropositive patients with RA, should be performed routinely. | |
22854346 | Intermediate- to long-term results after hybrid total hip arthroplasty in patients with rh | 2013 Feb | There have been few reports describing intermediate- to long-term results after hybrid total hip arthroplasty in patients with rheumatoid arthritis. We followed up 52 hips in 44 patients aged 5 men and 39 women, with a mean of 11.5 years (range, 5-23.5 years). Revisions had been performed in 6 hips in 6 patients: 1 both acetabular and femoral components for infection, 1 acetabular component for aseptic loosening, 3 acetabular components for recurrent dislocation, and 1 acetabular component for dislodgement of the polyethylene liner from the metal shell. None of other acetabular or femoral components were revised or found to be loose at the final follow-up. Although postoperative dislocation remains a concern, hybrid total hip arthroplasty had an acceptable result in patients with rheumatoid arthritis. | |
22546955 | Reexamination of the assessment criteria for rheumatoid arthritis disease activity based o | 2013 Mar | OBJECTIVE: To explore simpler and possibly more appropriate tools than the conventional Disease Activity Score 28 (DAS28) for assessing rheumatoid arthritis (RA) and to derive more reliable DAS28-based criteria. METHODS: The capabilities of assessing disease activities in 250 RA patients were compared between DAS28 and other methods, including the Simplified DA Index (SDAI), Clinical DA Index (CDAI), and Routine Assessment of Patient Index Data-3 (RAPID-3). RESULTS: SDAI and CDAI showed a good correlation and consistency with DAS28, whereas RAPID-3 yielded inferior results. In terms of remission criteria, DAS28 was less stringent than SDAI or CDAI; when RA remission was reexamined based on more stringent SDAI or CDAI criteria, cut-off values for DAS28-C-reactive protein of <1.72 were considered to be appropriate. The conventional DAS28 was considered to be appropriate for assessing low, middle and high disease activities because it provides criteria similar to or more stringent than those of other methods, while SDAI and CDAI were considered to be simpler and more appropriate criteria for assessing remission. CONCLUSION: For assessing remission, DAS28-CRP provides the most appropriate criterion of the methods compared when the currently used cut-off value of 2.3 is lowered to a new value of 1.72. | |
22219137 | Genetic predisposition of the severity of joint destruction in rheumatoid arthritis: a pop | 2012 May | BACKGROUND: The susceptibility to rheumatoid arthritis (RA) is partly heritable, but whether the severity of RA is also influenced by genetics has not been determined. The evaluation of the heritability of the severity of RA is basic to further studies on genetic factors. A study was undertaken to determine whether joint destruction is heritable. METHODS: Iceland has an unique comprehensive genealogy database covering today's population and stretching back to ≥1000 years ago, as well as genome-wide single nucleotide polymorphism data for a large part of the population. Hand and feet x-rays of 325 Icelandic patients with RA were scored according to the Sharp-van der Heijde method. The degree of relatedness between patients was estimated in two ways: (1) kinship coefficients (KC) on the genealogical data were expressed; and (2) the identical-by-descent (IBD) was estimated applying long-range phasing of the genetic profile of the patients. The degree of relatedness was tested against the similarity in joint destruction rates by linear regression analysis and the heritability of joint destruction was calculated. RESULTS: Significant associations between degree of relatedness and similarity in joint destruction rates were observed for both methods of determining relatedness (p(KC)=0.018, p(IBD)=0.003). The estimated heritability was 45% using KC and 58% using the estimated IBD data. CONCLUSIONS: The severity of joint destruction in RA is influenced by genetic factors. | |
22771133 | Disease activity in rheumatoid arthritis patients at initiation of biologic agents and 1 y | 2013 Mar | OBJECTIVE: In Switzerland, the prescription of biologic antirheumatic agents in rheumatoid arthritis (RA) patients is not limited by stringent requirements from health authorities. The goals of this study were to: determine the characteristics of the Swiss patients at the initiation of biologics, compare them with other countries and evaluate whether different disease activity levels at initiation of therapy, resulting from distinct access to these treatment, influence their effectiveness. METHODS: This is a retrospective cohort study of RA patients followed in the Swiss register (SCQM-RA). Two thousand and sixty patients treated with biologics were retrieved. We present the disease characteristics and the patients' demographic data, at initiation and some effectiveness data after 1 year of treatment. RESULTS: Two thousand and sixty patients treated with biologics were retrieved. At initiation of treatment, the mean disease activity DAS (SD): 4.4 (1.4), number of previous antirheumatic treatments: 1.1, functional status HAQ: 1.1 (0.7) and median duration of illness: 5.5 years were significantly lower than in other published registries. The mean DAS: 3.3 (1.4) 1 year after initiation of therapy also appears lower than in other countries. Additionally, patients treated more recently (after 2005) had a significantly higher improvement in mean DAS. CONCLUSIONS: Data from the Swiss RA registry demonstrate that biologics are prescribed at a lower level of disease activity and after fewer prior DMARD failures than in most other countries, a practice that seems to correlate with overall lower absolute levels of disease activity and better patient outcomes after 1 year of treatment. | |
22045838 | Effects of smoking on disease activity and radiographic progression in early rheumatoid ar | 2011 Dec | OBJECTIVE: To analyze the effects of cigarette smoking on disease activity and radiographic damage in patients with early rheumatoid arthritis (RA). METHODS: Study subjects were 156 patients with early RA (< 2 yrs). Disease activity, therapeutic response, and radiographic progression were compared in smokers and nonsmokers at 24 months. RESULTS: At baseline, ever-smokers had earlier disease onset and a closer association with the shared epitope (SE), but not more seropositive disease. No significant differences were observed in disease activity and European League Against Rheumatism therapeutic responses between smokers and nonsmokers. Multivariate analysis showed that baseline Larsen score, the HLA-DRB*04 genotype, being female, and current smoking were associated with radiographic progression. CONCLUSION: In patients with early RA, smoking was associated with earlier disease onset and the SE. Smoking was an independent factor of radiographic progression. | |
22270231 | Problems and accommodation strategies reported by computer users with rheumatoid arthritis | 2012 Sep | INTRODUCTION: Little is known about the problems experienced by and the accommodation strategies used by computer users with rheumatoid arthritis (RA) or fibromyalgia (FM). This study (1) describes specific problems and accommodation strategies used by people with RA and FM during computer use; and (2) examines if there were significant differences in the problems and accommodation strategies between the different equipment items for each diagnosis. METHODS: Subjects were recruited from the Arthritis Network Disease Registry. Respondents completed a self-report survey, the Computer Problems Survey. Data were analyzed descriptively (percentages; 95% confidence intervals). Differences in the number of problems and accommodation strategies were calculated using nonparametric tests (Friedman's test and Wilcoxon Signed Rank Test). RESULTS: Eighty-four percent of respondents reported at least one problem with at least one equipment item (RA = 81.5%; FM = 88.9%), with most respondents reporting problems with their chair. Respondents most commonly used timing accommodation strategies to cope with mouse and keyboard problems, personal accommodation strategies to cope with chair problems and environmental accommodation strategies to cope with monitor problems. CONCLUSIONS: The number of problems during computer use was substantial in our sample, and our respondents with RA and FM may not implement the most effective strategies to deal with their chair, keyboard, or mouse problems. This study suggests that workers with RA and FM might potentially benefit from education and interventions to assist with the development of accommodation strategies to reduce problems related to computer use. | |
23866466 | Rituximab therapy for flare-up of rheumatoid arthritis after total knee replacement surger | 2012 Oct | A variety of drug types are used alone or in combination to manage Rheumatoid Arthritis along with physiotherapy. We report herein the case of a 51 year old female patient with a history of Rheumatoid Arthritis whose disease remained active despite being on routinely used multiple disease modifying antirheumatic drugs. The patient underwent bilateral total knee arthroplasty with subtotal synovectomy due to the severe pain caused by her concomitant age related osteoarthritis which was only aggravated by her active rheumatoid arthritis disease. Three months following surgery, the patient's knee pain with typical rheumatoid flare and swelling reappeared for which a B cell monoclonal antibody, rituximab, was given. Her number of tender and swollen joints reduced to less than three and her C-reactive protein levels and erythrocyte sedimentation rate reduced significantly along with considerable improvement in her Global Assessment score. Her severity of pain also decreased to 3 from an initial score of 8 on the Visual Analog Scale. Thus, Rituximab helped improve our patient's symptoms from recurrence of synovitis after total knee replacement. | |
21279992 | Body mass index and clinical response to infliximab in rheumatoid arthritis. | 2011 Feb | OBJECTIVE: Adipose tissue has immunomodulating effects in rheumatoid arthritis (RA), although the exact role is, at present, unclear. The purpose of this study was to determine whether body mass index (BMI) affects response to infliximab in RA patients investigated prospectively. METHODS: In 89 patients with active RA, the BMI was calculated before initiation of infliximab treatment (3 mg/kg intravenously). After 16 weeks of treatment, changes in disease activity were assessed with the Disease Activity Score in 28 joints (DAS28). RESULTS: The mean ± SD BMI was 26 ± 5 kg/m(2) (range 17-42). The BMI correlated positively with the DAS28 at baseline (r = 0.34, P = 0.001). Since selection of study patients according to DAS28 values could influence the clinical response to tumor necrosis factor (TNF) blockade due to regression to the mean because the clinical response is itself based on the change in the DAS28 values, analysis of covariance was used to correct for the baseline DAS28. A highly significant, negative association between the BMI and the absolute decrease in the DAS28 after 16 weeks (P = 0.001) was found also when adjusted for anti-citrullinated protein antibodies. CONCLUSION: Although the infliximab dosage is based on body weight, RA patients with a high BMI responded less well to infliximab, a finding that held true when adjusted for the baseline DAS28 or anti-citrullinated protein antibody status. These results support the notion that adipose tissue may be involved in the pathophysiology of RA and could have implications for other immune-mediated inflammatory conditions treated with TNF antagonists. | |
21789609 | Proposing a method of regional assessment and a novel outcome measure in rheumatoid arthri | 2012 Aug | We proposed a method of regional assessment in patients with rheumatoid arthritis. The utility of this method was demonstrated by assessing drug efficacy in patients who received infliximab (n = 31) or tocilizumab (n = 6). Joints were divided into four regions: upper/large, upper/small, lower/large, and lower/small. The total joint index was calculated as follows: the sum of tender and swollen joint counts divided by the number of evaluable joints in each region. At the baseline, the total joint index of the upper/small region was the lowest and that of the lower/large region was the highest compared with other regions. The change in the total joint index from the baseline to the 30-week point (Δ) did not differ among the four regions. There were significant close relations of Δ between the upper/small and the upper/large region and between the lower/small and the lower/large region. This method allows us to focus on a specific region and to compare and contrast among them. | |
23060009 | In patients with early rheumatoid arthritis, the new ACR/EULAR definition of remission ide | 2013 Feb | OBJECTIVES: To test the American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) and disease activity score in 44 and 28 joints (DAS, DAS28) definitions of remission in early rheumatoid arthritis (RA), against disability and ultrasound-detectable synovitis. METHODS: In an observational study of early RA patients, remission rates were determined and compared in 166 patients. The remission definitions included the simplified disease activity index (SDAI≤3.3), ACR/EULAR (categorical), DAS28 (<2.6) and DAS (<1.6). The health assessment questionnaire (HAQ) was completed at baseline and 12 months, power Doppler-positive synovitis (PDPS) was assessed at baseline, 6 and 12 months. Cross-sectionally, the outcomes were low functional disability (HAQ≤0.5) or absent PDPS in all joints, while longitudinally the outcomes were stable low functional disability and persistent absent PDPS in all joints. RESULTS: At baseline, 33.7% of patients achieved DAS28 remission, 43.37% DAS remission, 16.8% SDAI remission, 13.8% ACR/EULAR remission. DAS28, SDAI and ACR/EULAR remission was cross-sectionally associated with low functional disability and absent PDPS. All definitions were longitudinally associated with low functional disability: positive likelihood ratios (LR+) of 3.24 for DAS28, 2.14 for DAS, 4.86 for SDAI, 5.67 for ACR/EULAR criteria, and with absent PDPS for DAS28 (LR+ 1.66), SDAI (LR+ 6.46), ACR/EULAR (LR+ 5.07). CONCLUSIONS: The new remission definitions confirmed their validity in an observational setting and identify patients with better disease control. | |
21847543 | Synovial tissue heterogeneity and peripheral blood biomarkers. | 2011 Oct | Rheumatoid arthritis is characterized by multiple pathobiological processes and heterogeneous clinical phenotypes. Not surprisingly, the inflamed synovium harbors an equally complex pathology. This includes variability in infiltrating and resident cell populations, spatial arrangements, and cell-cell interactions, as well as gene expression profiles. Remarkable progress in our understanding of the many facets of tissue heterogeneity has been facilitated by the increasing availability of patients' material and the development of advanced research technologies. The next challenge is to capitalize on the large amount of data generated to elucidate the specific pathogenic pathways disparately activated in different patients and/or different phases of the disease. When tissue pathology can be reliably explored through noninvasive circulating biomarkers, then the circle will be closed. We attempt to highlight key advances in the understanding of synovial tissue heterogeneity in rheumatoid arthritis and summarize novel perspectives in synovial biomarker discovery in relation to peripheral blood. | |
23052558 | [Presurgical and postsurgical orthotic management of the rheumatoid foot]. | 2012 Oct | Foot complaints remain frequent in patients with rheumatoid arthritis (RA) even in the era of biological anti-rheumatic drugs. Orthotic management of rheumatoid foot disorders is able to improve mobility and thus the quality of life in RA patients. This article highlights the preoperative and postoperative orthotic management of the rheumatoid arthritic foot. |
