24359405 | Rheumatoid arthritis and outcomes in first and subsequent births based on data from a nati | 2014 Mar | OBJECTIVE: To examine associations between rheumatoid arthritis (RA) and pregnancy outcomes in first and subsequent births. DESIGN: Cohort study. SETTING: Study based on data registered in the Medical Birth Registry of Norway from the period 1 December 1998 to 31 December 2009. POPULATION: Singleton births in women recorded with RA (n = 1496) and reference deliveries from the general population (n = 625,642). METHODS: Outcomes of first and subsequent births were analyzed separately. First birth was defined as the first delivery of nulliparous women. Associations between RA and maternal and perinatal outcomes were assessed in logistic regression analyses and adjusted for maternal age at delivery, gestational age, smoking habits and for previous cesarean section when relevant. MAIN OUTCOME MEASURES: Maternal and perinatal outcomes. RESULTS: Vaginal bleeding was observed more often among women with RA both in first pregnancy [adjusted odds ratio (aOR) 1.8, 95% CI 1.3-2.4] and in subsequent pregnancies (aOR 1.4, 95% CI 1.1-1.9). Elective cesarean section was more common among women with RA both in the first birth (aOR 2.0, 95% CI 1.4-2.8) and in subsequent births (aOR 1.5, 95% CI 1.2-2.0). Preterm delivery was more frequent among women with RA than the reference population in first pregnancy (aOR 1.5, 95% CI 1.1-2.0) and in subsequent pregnancies (aOR 1.5, 95% CI 1.1-1.9). CONCLUSION: Complications and poor pregnancy outcomes were more often observed in women with RA and the greatest differences were observed in the first pregnancy. | |
23619158 | Peripheral joint inflammation in early onset spondyloarthritis is not specifically related | 2014 Apr | OBJECTIVES: A pivotal MRI study of knee arthritis indicated that enthesitis was more frequently observed in established spondyloartritis (SpA) than rheumatoid arthritis (RA). Subsequent MRI and ultrasound studies, however, failed to consistently demonstrate primary synovitis in RA versus primary enthesitis in SpA. Therefore, the current study aimed to reassess enthesitis versus synovitis in peripheral arthritis by a combined imaging and histopathological study in early untreated disease. METHODS: MRI and mini-arthroscopic synovial biopsy sampling were performed in 41 patients with early untreated knee or ankle arthritis, who were diagnosed with SpA (n=13), RA (n=20) or crystal arthropathy (n=8) at follow-up. MRI evaluation of enthesitis and synovitis, and immunohistochemical characterisation of synovitis were performed by two observers blinded to diagnosis. RESULTS: MRI showed similar prevalence of perientheseal fluid/oedema (67% vs 75%), perientheseal bone marrow oedema (0% vs 10%) and entheseal enhancement (46% vs 47%) in SpA versus RA, respectively. The number and distribution of affected entheseal sites were not different between both diseases. The MRI synovitis score was significantly higher in SpA (median 1.4; IQR 1.1-1.5) compared with RA (median 0.5; IQR 0.0-1.3) (p=0.028). Synovial histopathology showed a numerical increase in infiltrating cells in SpA versus RA synovitis which reached significance for CD163 macrophages in the synovial sublining (p=0.030). There were no differences compared with the crystal arthropathy control group. CONCLUSIONS: Enthesitis on MRI is not a specific feature of peripheral arthritis in recent onset SpA versus RA. Synovitis is prominent in both diseases as evaluated by MRI and immunohistochemistry. | |
24780657 | Septic arthritis in the era of immunosuppressive treatments. | 2014 Mar | Immunosuppressants have been the mainstay of treatment for certain inflammatory joint conditions for many years. Developments in this field, namely biological treatments, have led to a change in the classical presentation of acute bone, joint and soft tissue infections. The normal findings of severe pain and tenderness on examination may be absent or simply mimic a typical exacerbation of the chronic joint condition. A minimally raised white cell count and elevated C-reactive protein in the absence of systemic signs of infection may be interpreted as further evidence for the diagnosis of an exacerbation of inflammatory arthritis. We present a unique case of recurrent polyarticular septic arthritis in a patient treated with immunosuppression for refractory rheumatoid arthritis. We hope this article will enable doctors to appreciate and recognise the changing face of septic arthritis in the modern era of immunosuppressant treatments. | |
24833758 | Determinants associated with work participation in patients with established rheumatoid ar | 2014 Jul | OBJECTIVE: Reduced work participation (WP) is a common problem for patients with rheumatoid arthritis (RA) and generates high costs for society. Therefore, it is important to explore determinants of WP at the start of tumor necrosis factor inhibitor (TNFi) treatment, and for changes in WP after 2 years of TNFi treatment. METHODS: Within the Dutch Rheumatoid Arthritis Monitoring (DREAM) biologic register, WP data were available from 508 patients with RA younger than 65 years and without an (early) retirement pension. WP was registered at start of TNFi treatment and after 2 years of followup and was measured by single patient-reported binary questions whether they had work, paid or voluntary, or had a disability allowance or a retirement pension. Determinants measured at baseline were age, sex, disease duration, functional status [through Health Assessment Questionnaire-Disability Index (HAQ-DI)], 28-joint Disease Activity Score (DAS28), rheumatoid factor, presence of erosions, number of previous disease-modifying antirheumatic drugs, and number of comorbidities. During the 2 years of followup, HAQ-DI response and European League Against Rheumatism response were measured. Univariate analyses (excluded if p value was > 0.2) and multivariate (excluded if p value was > 0.1) logistic regression analyses were used. RESULTS: Determinants associated with WP at baseline were having a better HAQ-DI (OR 0.32, p = 0.000) and male sex (OR 0.65, p = 0.065). After 2 years of TNFi therapy, 11.8% (n = 60) started to work and 13.6% (n = 69) stopped working. Determinants associated with starting to work were better baseline HAQ-DI (OR 0.58), positive RF (OR 2.73), and young age (OR 0.96); and for stopping work, worse baseline HAQ-DI (OR 2.74), low HAQ-DI response (OR 0.31), and comorbidity (OR 2.67), all with p < 0.1. CONCLUSION: Young patients with RA and a high functional status without any comorbidity will have a better chance of working. This supports the main goal in the management of RA: to suppress disease activity as soon and as completely as possible to prevent irreversible destruction of the joints, and thus maintain a good functional status of the patient. Because of the low proportion of variance explained by the models in this study, other factors besides the ones studied are associated with WP. | |
23934385 | The impact of conventional DMARD and biological therapies on CD4+ cell subsets in rheumato | 2014 Feb | Rheumatoid arthritis (RA) is an autoimmune disease characterized by abnormal prevalence of Th1, Th2, Th17, and regulatory (Treg) subsets. Some data suggest that these subsets are influenced by anti-RA agents. Follow-up studies monitoring T cell phenotype in response to therapy are limited. We investigated the alteration of CD4+ T cell subset distribution after the initiation of disease-modifying antirheumatic drug (DMARD) (with glucocorticosteroid (GCS) and methotrexate (MTX)) and anti-TNFα therapy. We enrolled 19 treatment naive (early) RA patients and initiated GCS (in a dose of 16 mg/day for 4 weeks; then 8 mg/day). MTX, 10 mg/week, was started at week 4. We also enrolled 32 RA patients unresponsive to DMARD and initiated anti-TNFα therapy: adalimumab (ADA), 40 mg/2 weeks, n = 12; etanercept (ETA), 50 mg/weeks, n = 12; or infliximab (IFX) on week 0, 2, and 6, 3 mg/kg bw, n = 8. Blood was taken before and 4 and 8 weeks after the initiation of therapy. Ten volunteers served as controls. The T cell phenotype was assessed with flow cytometry. In early RA, Th1, Th2, and Th17 prevalence was higher, while Treg prevalence was lower than normal. GCS alone decreased Th2 prevalence. GCS + MTX decreased Th17 prevalence. Immune phenotype in unresponsive RA before anti-TNF therapy was as in early RA. Four and 8 weeks after initiating anti-TNF therapy, Th1 prevalence was higher than baseline in ETA or IFX, while it was stable in ADA groups. Th2 prevalence was higher than normal in ADA or IFX, while normalized in ETA group. In each group, Treg prevalence increased, while Th17 prevalence was at the baseline. The proinflammatory immune phenotype is normalized only under GCS + MTX combination in early RA. Anti-TNFα therapy exhibit marked effects on all the cell populations investigated (except Th17); some slight differences in this action exist between ADA, ETA, and IFX therapy. | |
22524332 | Periodontal condition of patients with autoimmune diseases and the effect of anti-tumor ne | 2013 Feb | BACKGROUND: The aim of this study is to evaluate the effect of autoimmune diseases (AIs), as well as anti-tumor necrosis factor-α (TNF-α) therapy on the clinical and immunologic parameters of the periodontium. METHODS: Thirty-six AI patients (12 rheumatoid arthritis [RA], 12 psoriatic arthritis, and 12 systemic sclerosis) were recruited together with 12 healthy (H) and 10 RA patients receiving anti-TNF-α therapy (RA+). Periodontal indices including plaque index, gingival index (GI), probing depth (PD), and bleeding on probing (BOP) were measured, and gingival crevicular fluid (GCF) was collected from five deepest pockets using papers strips. The TNF-α level was analyzed using enzyme-linked immunosorbent assay. Analysis of variance test was used for statistical comparison between groups, whereas Pearson linear correlation coefficient test was used to examine the association between TNF-α and periodontal status indices. RESULTS: The three AI subgroups were very similar in clinical and immunologic parameters. GI was greater in the AI patients compared to the H and RA+ groups (1.91 ± 0.54, 1.21 ± 0.67, and 1.45 ± 0.30, respectively, P = 0.0005). AI patients exhibited significantly more BOP than H and RA+ (46.45% ± 17.08%, 30.08% ± 16.86%, and 21.13% ± 9.51%, respectively, P = 0.0002). PD in H and RA+ groups were lower than in the AI (3.47 ± 0.33, 3.22 ± 0.41, and 3.91 ± 0.49 mm, P = 0.0001). Number of sites with PD >4 mm was higher in AI patients compared to H and RA+ (42.44 ± 17.5 versus 24.33 ± 15.62 versus 33.3 ± 6.6, P = 0.0002). GCF TNF-α was higher among the AI patients (1.67 ± 0.58 ng/site) compared to 1.07 ± 0.33 ng/site for the H group and 0.97 ± 0.52 ng/site for the RA+ group (P = 0.0002). A significant positive correlation was found between PD and TNF-α levels in the GCF (r = 0.4672, P = 0.0002), BOP (r = 0.7491, P = 0.0001), and GI (r = 0.5420, P = 0.0001). CONCLUSIONS: Patients with AI diseases have higher periodontal indices and higher TNF-α levels in GCF than H controls. Anti-TNF-α treatment appears to reverse this phenomenon. | |
24817699 | CD70-expressing CD4 T cells produce IFN-γ and IL-17 in rheumatoid arthritis. | 2014 Oct | OBJECTIVE: CD70-expressing CD4 T cells are enriched in RA and promote autoimmunity via co-stimulatory CD70-CD27 interaction. This study aimed to explore the phenotype and cytokine production of CD70(+) CD4 T cells in RA. METHODS: Peripheral blood mononuclear cells from 32 RA patients were isolated and frequencies of CD70(+) cells within different CD4 T subsets were analysed using flow cytometry. IFN-γ and IL-17 production were compared between the CD70(+) and CD70(-) cells. Expression of master transcription factors T-bet, GATA3 and retinoic acid-related orphan receptor gamma t (RORγt) were examined by real-time PCR. Results are presented as mean (s.e.m.). RESULTS: CD4 T cells of healthy controls rarely expressed CD70 as compared with CD4 T cells of RA patients [mean 0.9% (s.e.m. 0.3%) vs 7.6 (0.6), P < 0.001]. In RA, CD70(+) cells were present within all CD4 T cell subsets, i.e. CD45RA(+)CCR7(+) naive, CD45RA(-)CCR7(+) central memory, CD45RA(-)CCR7(-) effector memory and CD45RA(+)CCR7(-) terminally differentiated effector memory T cells with a mean frequency of 3.9% (s.e.m. 1.1%), 4.0 (0.5), 4.2 (0.7) and 9.4 (4.3), respectively. As compared to CD70(-) CD4 T cells, CD70(+) CD4 T cells produced significantly more IFN-γ and IL-17 after short activation. CD70(+) CD4 T cells preferentially expressed transcription factor RORγt. CONCLUSION: CD70(+) CD4 T cells are enriched in RA and may directly contribute to RA pathogenesis by producing IFN-γ and IL-17. Targeting CD70(+) CD4 T cells might offer new therapeutic opportunities in RA. | |
25365778 | Mindfulness and cognitive-behavioral interventions for chronic pain: differential effects | 2015 Feb | OBJECTIVE: This study compared the impact of cognitive-behavioral therapy for pain (CBT-P), mindful awareness and acceptance treatment (M), and arthritis education (E) on day-to-day pain- and stress-related changes in cognitions, symptoms, and affect among adults with rheumatoid arthritis (RA). METHOD: One hundred forty-three RA patients were randomized to 1 of the 3 treatment conditions. CBT-P targeted pain-coping skills; M targeted awareness and acceptance of current experience to enhance coping with a range of aversive experiences; E provided information regarding RA pain and its management. At pre- and posttreatment, participants completed 30 consecutive evening diaries assessing that day's pain, fatigue, pain-related catastrophizing and perceived control, morning disability, and serene and anxious affects. RESULTS: Multilevel models compared groups in the magnitude of within-person change in daily pain and stress reactivity from pre- to posttreatment. M yielded greater reductions than did CBT-P and E in daily pain-related catastrophizing, morning disability, and fatigue and greater reductions in daily stress-related anxious affect. CBT-P yielded less pronounced declines in daily pain-related perceived control than did M and E. CONCLUSIONS: For individuals with RA, M produces the broadest improvements in daily pain and stress reactivity relative to CBT-P and E. These findings also highlight the utility of a diary-based approach to evaluating the treatment-related changes in responses to daily life. | |
23320107 | Association of increased frequencies of HLA-DPB1*05:01 with the presence of anti-Ro/SS-A a | 2013 | INTRODUCTION: Autoantibodies to ribonucleoprotein are associated with a variety of autoimmune diseases, including rheumatoid arthritis (RA). Many studies on associations between human leukocyte antigen (HLA) alleles and RA have been reported, but few have been validated in RA subpopulations with anti-La/SS-B or anti-Ro/SS-A antibodies. Here, we investigated associations of HLA class II alleles with the presence of anti-Ro/SS-A or anti-La/SS-B antibodies in RA. METHODS: An association study was conducted for HLA-DRB1, DQB1, and DPB1 in Japanese RA and systemic lupus erythematosus (SLE) patients that were positive or negative for anti-Ro/SS-A and/or anti-La/SS-B antibodies. RESULTS: An increased prevalence of certain class II alleles was associated with the presence of anti-Ro/SS-A antibodies as follows: DRB1*08:03 (Pc = 3.79×10(-5), odds ratio [OR] 3.06, 95% confidence interval [CI] 1.98-4.73), DQB1*06:01 (Pc = 0.0106, OR 1.70, 95%CI 1.26-2.31), and DPB1*05:01 (Pc = 0.0040, OR 1.55, 95%CI 1.23-1.96). On the other hand, DRB1*15:01 (Pc = 0.0470, OR 3.14, 95%CI 1.63-6.05), DQB1*06:02 (Pc = 0.0252, OR 3.14, 95%CI 1.63-6.05), and DPB1*05:01 (Pc = 0.0069, OR 2.27, 95% CI 1.44-3.57) were associated with anti-La/SS-B antibodies. The DPB1*05:01 allele was associated with anti-Ro/SS-A (Pc = 0.0408, OR 1.69, 95% CI 1.19-2.41) and anti-La/SS-B antibodies (Pc = 2.48×10(-5), OR 3.31, 95%CI 2.02-5.43) in SLE patients. CONCLUSION: HLA-DPB1*05:01 was the only allele associated with the presence of both anti-Ro/SS-A and anti-La/SS-B antibodies in Japanese RA and SLE patients. | |
24189759 | Intramuscular neridronate in patients with rheumatoid arthritis using corticosteroids: eva | 2013 Jun 1 | BACKGROUND AND AIMS: Oral bisphosphonates have been used successfully in patients with rheumatoid arthritis (RA), but their use for the treatment of corticosteroid induced osteoporosis may be limited by poor compliance. Neridronate, an intramuscular and intravenous aminobisphosphonate approved for the treatment of osteogenesis imperfecta and Paget's disease, is also effective in postmenopausal osteoporosis. The aim of this study was to compare the adherence of intramuscular neridronate versus oral alendronate or risedronate in patients with RA with corticosteroid-induced osteopenia. METHODS: This randomised, open label, parallel-group, single centre study enrolled post-menopausal women (50-70 years), with RA and osteopenia (T-score >-2.5) who were receiving stable dose of methylprednisolone 5 mg or equivalent within the previous 3 months, and expected to continue therapy for at least 12 months. Patients were treated with intramuscular neridronate 25 mg administered once a month, or oral alendronate 70 mg or oral risedronate 35 mg both administered once-weekly, for 12 months. The main outcome measure was adherence to treatment over 1 year, assessed using the Morisky Medication Adherence Scale 4-item (MMAS-4; adherence defined as patients with MMAS-4 score ≥3). RESULTS: Of 87 women (mean age 61.5 ± 9.2 years) enrolled, 30 were randomized to neridronate, 27 to alendronate and 30 to risedronate therapy. Adherence rates after 12 months were significantly higher with neridronate than with alendronate or risedronate (76.7% vs 47.8% and 48.0%; p<0.05 for both versus neridronate). After 12 months, lumbar and femoral neck BMD and DAS28 were significantly improved in all groups compared with baseline (p<0.05) with no significant difference between the three treatment groups. CONCLUSION: Neridronate is associated with significantly improved adherence to therapy compared with alendronate and risedronate, and improves BMD and disease activity in postmenopausal women with RA and osteopenia. Intramuscular monthly neridronate represents a convenient treatment option for patients with RA using corticosteroids. | |
24293579 | Update on the OMERACT magnetic resonance imaging task force: research and future direction | 2014 Feb | Magnetic resonance imaging (MRI) provides an important biomarker across a range of rheumatological diseases. At the Outcome Measures in Rheumatology (OMERACT) 11 meeting, the MRI task force continued its work of developing and improving the use of MRI outcomes for use in clinical trials. The breadth of pathology in the Rheumatoid Arthritis MRI Score has been strengthened with further work on the development of a joint space narrowing score, and a series of exercises presented at OMERACT 11 demonstrated good reliability and construct validity for this assessment. Understanding the importance of residual inflammation after RA treatment remains a major focus of the group's work. Analyses were presented on defining the level of synovitis (using MRI scores of a single hand) that would predict absence of erosion progression. The development of the OMERACT Hand Osteoarthritis MRI score has continued with substantial work presented on its iterative development, including pathology definition, scaling, and subsequent reliability of the score. Optimizing the role of MRI as a robust biomarker and surrogate outcome remains a priority for this group. | |
25269140 | [TNF inhibitors and myelitis: think about it, even lately]. | 2014 Sep | Anti-TNF medications have been widely used for the treatment of auto-immune disease and new drugs are regularly approved. We report here a case of late myelitis after more than 6 years of adalimumab in a 74-year-old woman treated for rheumatoid polyarthritis. | |
23506671 | Treatment of rheumatoid arthritis in the Medicare Current Beneficiary Survey. | 2013 Mar 18 | INTRODUCTION: Numerous studies across different health systems have documented that many patients with rheumatoid arthritis (RA) do not receive disease-modifying anti-rheumatic drugs (DMARDs). Relatively little is known about correlates of DMARD use and whether there are socioeconomic and demographic disparities. We examined DMARD use during 2001 to 2006 in the Medicare Current Beneficiary Survey (MCBS), a longitudinal US survey of randomly selected Medicare beneficiaries. METHODS: Participants in MCBS with RA were included in the analyses, and DMARD use was based on an in-home assessment of all medications. Variables included as potential correlates of DMARD use in weighted regression models included race/ethnicity, insurance, income, education, rheumatology visit, region, age, gender, comorbidity index, and calendar year. RESULTS: The cohort consisted of 509 MCBS participants with a diagnosis code for RA. Their median age was 70 years, 72% were female, and 24% saw a rheumatologist. Rates of DMARD use ranged from 37% among those <75 years of age to 25% of those age 75 to 84 and 4% of those age 85 and older. The multivariable adjusted predictors of DMARD use include: visit with a rheumatologist in the prior year (odds ratio, OR, 7.74, 95% CI, 5.37, 11.1) and older patient age (compared with <75 years, ages 75 to 84, OR 0.58, 95% CI 0.37, 0.92, and 85 and over, OR 0.09, 95% CI 0.02, 0.31). In those without a rheumatology visit, lower income and older age were associated with a significantly reduced probability of DMARD use; no association of DMARD use with income or age was observed for subjects seen by rheumatologists. Race and ethnicity were not significantly associated with receipt of DMARDs. CONCLUSIONS: Among individuals not seeing rheumatologists, lower income and older age were associated with a reduced probability of DMARD use. | |
23961669 | [Etanercept]. | 2013 Jul | Etanercept (ETN) is a fusion protein of the receptor (CD120b) for tumor necrosis factor (TNF) and the Fc portion of IgG1. A phase III trail and the JESMR study, both performed in Japan, implicated the importance of concomitant methotrexate (MTX) use in the treatment of rheumatoid arthritis (RA). Further evidences, including the TEAR study and the PRESERVE study, supported the recent treatment strategy for RA, being divided into at least two phases: remission induction phase(step-up or initial combination) and its maintenance phase (step-down). Thus, optimization of RA treatment chiefly based on MTX and anti-TNF biological agents is in progress. | |
24524085 | Interleukin 6 and rheumatoid arthritis. | 2014 | Interleukin-6 (IL-6) is a representative cytokine featuring pleiotropic activity and redundancy. A transient synthesis of IL-6 contributes to host defense against infectious agents and tissue injuries by inducing acute phase reactions and immunological and hematopoietic responses. However, uncontrolled persistent production of IL-6 may lead to the development of several immune-mediated diseases. Rheumatoid arthritis (RA) is a chronic disease with joint and systemic inflammation resulting from immunological abnormalities and it has been found that IL-6 plays a key role in the development of this disease. Clinical trials in various parts of the world of tocilizumab, a humanized anti-IL-6 receptor antibody, have proved its efficacy and tolerable safety either as monotherapy or in combination with disease-modifying antirheumatic drugs. As a result, it is currently used as a first-line biologic for the treatment of moderate-to-severe RA in more than 100 countries. Clarification of the mechanism(s) through which tocilizumab exerts its effect on RA and of the reason(s) why IL-6 is continuously produced in RA can be expected to lead to the best use of this agent for RA patients and aid in investigations into the pathogenesis of RA. | |
23408767 | Association of high body mass index with decreased treatment response to combination thera | 2013 Aug | OBJECTIVE: To assess the association between high body mass index (BMI) and treatment response in recent-onset rheumatoid arthritis. METHODS: In the Behandelstrategieën voor Reumatoide Artritis (Treatment Strategies for Rheumatoid Arthritis) study, 508 patients were randomized to initial monotherapy or combination therapy with prednisone or infliximab (IFX). The response to Disease Activity Score (DAS) ≤2.4-steered treatment (first dose and after 1 year) was compared between patients with a BMI <25 kg/m(2) and ≥25 kg/m(2) , using relative risk (RR) regression analyses. DAS, components of DAS, and functional ability during the first year were compared using linear mixed models. RESULTS: High BMI was independently associated with failure to achieve a DAS ≤2.4 on initial therapy (RR 1.20 [95% confidence interval (95% CI) 1.05, 1.37]). The effect for combination therapy with prednisone was RR 1.55 (95% CI 1.06, 2.28) and for combination therapy with IFX 1.42 (95% CI 0.98, 2.06). The RRs for failure after 1 year were 1.46 (95% CI 0.75, 2.83) and 2.20 (95% CI 0.99, 4.92), respectively. High BMI was also associated with failure on delayed combination therapy with IFX, after adjustment for selection bias related to previous failure on disease-modifying antirheumatic drugs. No significant association was observed in the initial monotherapy groups. In the first year, patients with a high BMI had higher DAS and worse functional ability, with more tender joints and a higher visual analog scale global health, but not more swollen joints and similar systemic inflammation. CONCLUSION: High BMI was independently associated with failure to achieve low DAS on initial combination therapy with prednisone and on initial and delayed treatment with IFX. Patients with a high BMI experienced more pain, but not more swelling or systemic inflammation. | |
22461187 | Low prevalence of work disability in early inflammatory arthritis (EIA) and early rheumato | 2013 Feb | We determined the prevalence of work disability in early rheumatoid arthritis (ERA) and undifferentiated early inflammatory arthritis (EIA) patients at first enrollment into the Canadian Early Arthritis Cohort (CATCH) who met the 2010 ACR criteria versus those not meeting criteria, to determine the impact of meeting new criteria on work disability status. Data at first visit into the cohort were analyzed. Descriptive statistics and logistic regression analyses were performed to investigate the association of other variables in our database with work disability. 1,487 patients were enrolled in the CATCH study, a multi-site observational, prospective cohort of patients with EIA. 934 patients were excluded (505 based on missing criteria for ACR 2010 classification, as anti-CCP was absent, and 429 were not working for other reasons). Of the 553 patients included, 71 % were female with mean disease duration of 6.4 months. 524 (94.8 %) were employed while 29 (5.2 %) reported work disability at first visit. There were no differences between those meeting 2010 ACR criteria versus those who did not. Baseline characteristics associated with work disability were male gender, age, education, income, HAQ, and positive RF status. The mean HAQ score in work disabled patients was 1.4 versus 0.9 in those who were working (p < 0.001). Disease activity score (DAS28) was not associated with work disability (p = 0.069), nor was tender joint count, swollen joint count, anti-CCP, patient global assessment, or SF-12v2. In the regression model, work disability was associated with lower income levels (p = 0.01) and worse HAQ scores (OR 2.33; p = 0.001), but not significantly associated with male gender (p = 0.08), older age (>50 years; p = 0.3), lower education (p = 0.3) or RF positivity (p = 0.6). We found rates of work disability to be low at entry into this EIA cohort compared to previous studies. There may be potential for intervention in ERA to prevent the development of work disability. | |
23667170 | Patients' needs and expectations with regard to rheumatology nursing care: results of mult | 2013 Jun | OBJECTIVE: The contribution of rheumatology nurses to improved patient outcomes is increasingly recognised but more research is needed about the effects of interventions. The patient's role in deciding about healthcare quality is considered pivotal and therefore patients' opinions and expectations should be directional in defining priorities for a research agenda. The objective of this study was to explore needs and expectations with regard to rheumatology nursing care in patients with chronic inflammatory arthritis (CIA). METHODS: Patients aged 18-90 years from three medical clinics in different regions in The Netherlands were invited to participate in focus group interviews. The interviews were transcribed verbatim and independently analysed by the authors. In a consensus meeting the emerging subjects were categorised into themes which were verified in a fourth interview. RESULTS: In total, 20 patients, mean age 57 years old, participated in the focus group interviews. The majority had rheumatoid arthritis and mean disease duration was 15 years. The focus group interviews revealed 12 subthemes that were organised into four main themes: education, self-management support, emotional support and well organised care. Additionally, patients considered opinions about 'the personality of the nurse' (eg, easy to talk to) to be important. CONCLUSIONS: Patients with CIA mentioned that many problems have to be addressed when one is faced with having a rheumatic disease. The focus group interviews yielded valuable information about the care these patients need and expect. This information will direct future research with regard to rheumatology nursing care. | |
24336334 | Anti-carbamylated protein (anti-CarP) antibodies precede the onset of rheumatoid arthritis | 2014 Apr | OBJECTIVE: The presence of anti-citrullinated protein antibodies (ACPA) and IgM-rheumatoid factor (IgM-RF) years before the clinical diagnosis of rheumatoid arthritis (RA) suggests they are possibly involved in the pathogenic process underlying RA. In this study, we analysed whether anti-carbamylated protein (anti-CarP) antibodies, a novel autoantibody system against carbamylated proteins, can also be detected in healthy individuals before they developed RA. METHODS: Multiple sera from asymptomatic blood donors prior to the onset of their RA symptoms and sera from age-matched and sex-matched controls were tested for the presence of antibodies directed against carbamylated-fetal calf serum (Ca-FCS), carbamylated-fibrinogen (Ca-Fib), cyclic citrullinated-peptide 2 and IgM-RF. RESULTS: Anti-Ca-FCS and anti-Ca-Fib antibodies were each present in 27% and 38% of the last serum samples of blood donors prior to the diagnosis of RA. Both anti-Ca-FCS and anti-Ca-Fib antibodies could be detected many years before the onset of RA. Anti-CarP antibodies as well as ACPA are, on average, detected earlier than IgM-RF. CONCLUSIONS: In addition to ACPA and IgM-RF, also the newly identified anti-CarP antibodies appear many years before the diagnosis of RA. | |
25674272 | TNFAIP3 rs2230926 polymorphisms in rheumatoid arthritis of southern Chinese Han population | 2014 | Polymorphism of tumor necrosis factor alpha-induced protein 3 (TNFAIP3) has been be related to various auto-immune diseases. Based on previous studies that the single nucleotide polymorphism (SNP) of rs2230926 was association with rheumatoid arthritis (RA) of Japanese, Caucasian population and the northern Chinese Han population, we tested the alleles and geno-type frequencies of rs2230926 in TNFAIP3 to investigate whether rs2230926 is susceptible to RA of southern Chinese Han population. In our case-control association study, 207 RA patients fulfilling the American College of Rheumatology (ACR) 1987 criteria were compared with 199 unrelated healthy subjects. After testing the alleles and genotype frequencies of rs2230926, the airwise linkage disequilibrium (LD) was computed and odd ration (OR) and 95% confidence intervals (95% CI) were used for evaluating the susceptibility to RA. The SNP of rs2230926 of the cases and control subjects were conformed to the Hardy-Weinberg equilibrium (P = 0.02257). The significantly statistical differences in alleles of T, G were founded in the cases and controls (P = 0.0027, OR 0.417, 95% CI 0.232-0.749); the genetic types of rs2230926 were associated with a susceptibility to RA, with OR 0.375 (95% CI 0.198-0.707, P = 0.0018). In the present study, our results indicated that the genetic polymorphism of rs2230926 in TNFAIP3 may be a susceptible factor conferring risk for RA in southern Chinese Han population. |
