25074866 Association of MDR1 C3435T and RFC1 G80A polymorphisms with methotrexate toxicity and resp 2014 Sep OBJECTIVES: Methotrexate (MTX) is the most commonly used disease-modifying antirheumatic drug for the treatment of rheumatoid arthritis (RA). Genetic polymorphisms of reduced folate carrier (RFC1 G80A) and multi-drug resistance-1 (MDR1 C3435T) might affect MTX response and/or toxicity. The aim of this study was to find out if there is an association between those polymorphisms and MTX toxicity and/or response in Jordanian RA patients. METHOD: A genotyping approach was used to determine the studied polymorphisms in 159 RA patients. RESULTS: There was an association between RFC1 G80A and MDR1 C3435T polymorphisms with MTX toxicity. Patients with RFC1 80GG genotype were at higher risk for gastrointestinal toxicity (p = 0.036). Patients carrying at least one MDR1 3435T variant allele were at higher risk for MTX overall toxicity (p = 0.04), especially hepatotoxicity (p = 0.028). Furthermore, the distribution of RFC1 G80A polymorphism between males and females was significantly different. The variant genotype 80AA was found to be more in males than in females (60% vs. 31%) (p = 0.011). CONCLUSIONS: Our results suggest that genetic polymorphisms in methotrexate transporters affect the toxicity but not the response of MTX treatment. Further studies should be performed to have more conclusive results.
24389296 Smoking as a risk factor for the radiological severity of rheumatoid arthritis: a study on 2014 Jul BACKGROUND: Smoking is a risk factor for the development of anti -citrullinated protein antibodies (ACPA) positive rheumatoid arthritis (RA). Whether smoking predisposes to severe joint damage progression is not known, since deleterious, protective and neutral observations have been made. OBJECTIVE: To determine the effect of smoking on joint damage progression. METHODS: Smoking status was assessed in 3158 RA patients included in six cohorts (Leiden Early Arthritis Clinic (Leiden-EAC), BARFOT, Lund, Iceland, NDB and Wichita). In total 9412 radiographs were assessed. Multivariate normal regression and linear regression analyses were performed. Data were summarised in a random effects inverse variance meta-analysis. RESULTS: When comparing radiological progression for RA patients that were never, past and current smokers, smoking was significantly associated with more severe joint damage in Leiden-EAC (p=0.042) and BARFOT (p=0.015) RA patients. No significant associations were found in the other cohorts, though a meta-analysis on the six cohorts showed significantly more severe joint damage progression in smokers (p=0.01). Since smoking predisposes to ACPA, analyses were repeated with ACPA as additional adjustment factor. Then the association was lost (meta-analysis p=0.29). CONCLUSIONS: This multi-cohort study indicated that the effect of smoking on joint damage is mediated via ACPA and that smoking is not an independent risk factor for radiological progression in RA.
24945905 Severe low back pain in patients with rheumatoid arthritis is associated with Disease Acti 2015 Jan OBJECTIVE: To investigate the prevalence and associated factors of severe low back pain (LBP) among patients with rheumatoid arthritis (RA). METHODS: This cross-sectional study included 201 patients with RA without prior spinal surgery. Severe LBP was defined as that with a visual analog scale (VAS) score of ≥ 50 mm within the previous 4 weeks. Lumbar lesions, sagittal alignment, and disc degeneration were evaluated by plain standing X-rays and magnetic resonance imaging. Associated factors of severe LBP were evaluated using multiple logistic regression analysis. RESULTS: Forty-eight patients (23.8%) had LBP with a VAS score of ≥ 50 mm. Multivariate analysis indicated that the associated factors for severe LBP were female, smoking, and moderate and high disease activity on the Disease Activity Score in 28 joints-erythrocyte sedimentation rate (DAS28-ESR). There was no relationship between severe LBP and any radiological findings. Among DAS28-ESR subscores, patients with severe LBP had significantly higher tender joint counts and VAS scores for general health. CONCLUSIONS: The prevalence of severe LBP was relatively high in patients with RA. The factor most closely associated with severe LBP was Disease Activity Score, but not radiological findings. Severe LBP was related to the tender joint count or subjective complaints of RA.
25347362 Species cross-reactivity of rheumatoid factors and implications for immunoassays. 2015 Jan Rheumatoid factors (RFs) are antibodies recognizing other antibodies usually by binding to the Fc part, while heterophilic antibodies (HAbs) are antibodies reacting with immunoglobulins (Igs) from other species. In particular, RFs have been found to cause false positive results in sandwich immunoassays. In this work, we analyzed RF-positive and RF-negative sera for content of cytokines and for heterophilic reactions by enzyme-linked immunosorbent assay and bead-based sandwich immunoassays. All sera, including those with RFs, contained insignificant amounts of cytokines and chemokines, but RF-positive sera showed large false positive values for several cytokines when analyzed by fluorescent bead-based multiplex immunoassays. This non-specific binding could be minimized by reagents designed to block HAbs, i.e. by selected animal IgGs. Furthermore, sera positive for RFs reacted with several animal IgGs, when these were immobilized on beads or coated on the polystyrene surface in enzyme-linked immunosorbent assays. This reaction could be inhibited by human IgG and by agents designed to inhibit heterophilic reactions (i.e. mixtures of IgGs from different species). In conclusion, RFs and HAbs represent an identical/overlapping set of antibodies, causing false positive reactions in sandwich and other immunoassays. Such assays must be conducted in the presence of appropriate blocking agents, e.g. HBR+, and must be carefully controlled.
23385306 Shared care or nursing consultations as an alternative to rheumatologist follow-up for rhe 2014 Feb OBJECTIVES: To compare patient outcomes of three regimes of follow-up care for rheumatoid arthritis (RA) outpatients with low disease activity. METHODS: RA outpatients (n=287) with Disease Activity Score (DAS28-CRP)<3.2 and Health Assessment Questionnaire<2.5 from two Danish rheumatology clinics were randomised to 2-year follow-up by either: (1) planned rheumatologist consultations, (2) shared care without planned consultations or (3) planned nursing consultations. The primary outcome was change in disease activity. DAS28-CRP, Health Assessment Questionnaire, visual analogue scale (VAS)-pain, fatigue, global health, confidence and satisfaction, quality-of-life by the Short Form 12 and self-efficacy measured by the RA Self-Efficacy questionnaire and the Arthritis Self-Efficacy Scale, were recorded annually and safety measures were recorded. x-Rays of hands and feet were taken at baseline and at 2-year follow-up. Mixed effect models were used to explore differences between the three groups over time. RESULTS: At 2-year follow-up, the group allocated to nursing consultations had lower disease activity than the group that underwent rheumatologist consultations (DAS28-CRP -0.3, p=0.049). The nursing group increased their self-efficacy (Arthritis Self-Efficacy Scale 18.8, p=0.001), confidence (10.7, p=0.001) and satisfaction (10.8, p<0.001) compared with the rheumatologist group. The shared care group reported a transient lower satisfaction compared with the rheumatologist group after 1 year (-8.8, p=0.004). No statistically significant differences were seen in other outcome variables. CONCLUSIONS: It is safe to implement shared care and nursing consultations as alternatives to rheumatologist consultations for RA outpatients with low disease activity without deterioration in disease control. Nursing consultations can enhance patients' self-efficacy, confidence and satisfaction.
24824913 Evaluation of a new erosion score by musculoskeletal ultrasound in patients with rheumatoi 2014 Sep The objectives of this study are to evaluate a new semi-quantitative (0-5) musculoskeletal ultrasound (US) erosion score in patients with rheumatoid arthritis (RA) and to prove its usefulness in the detection of disease activity and success of therapy. Thirty-eight patients with RA (mean disease duration 10.1 ± 11.9 years) were enrolled. Start or change of therapy (DMARD/biologics) was an inclusion criterion. DAS28, laboratory (ESR and CRP) and US data were evaluated before new therapy initiation and after 1, 3, 6 and 12 months. Thirteen joints of the clinically more affected hand and forefoot (wrist and MCP, PIP, MTP joints 2-5) were analyzed for synovitis in grayscale (GS) and power Doppler (PD) US, tenosynovitis/paratenonitis in GS/PDUS (wrist, MCP level) and for erosions. Erosions were analyzed by a new semi-quantitative score (grade 0, no erosion; grade 1, <1 mm, grade 2, 1 to <2 mm; grade 3, 2 to ≤3 mm; grade 4, >3 mm; grade 5, multiple bone erosions). After 12 months, DAS28 decreased from 4.5 to 3.4 (p < 0.001), the synovitis score in GSUS from 26.3 to 12.8 (p = 0.001) and the synovitis score in PDUS from 10.6 to 4.1 (p < 0.001). The erosion score decreased from 21.5 to 18.1 (p = 0.046). There were longitudinal significant correlations between the new erosion score and both the DAS28 (r = 0.368; p = 0.025) and the synovitis score in PDUS (r = 0.365; p = 0.026) over a 1-year follow-up period. The new erosion score might be a useful tool for the evaluation of erosive changes by US in RA patients. In the course of DMARD and biologic therapy, it was responsive under 1-year follow-up examination.
23877489 Interleukin-27 as a potential therapeutic target for rheumatoid arthritis: has the time co 2013 Oct Interleukin (IL)-27 is a novel member of the IL-6/IL-12 family of cytokines with a broad range of pro- and anti-inflammatory properties. Recently, accumulating evidence has shown that IL-27 can play either a pathogenic or a protective role in animal models of inflammatory arthritis, depending upon the model and underlying pathogenic mechanisms. As to human system, elevated expression of IL-27 has clearly been detected in the synovial membranes and fluid from patients with rheumatoid arthritis (RA). Moreover, stimulation of IL-27 receptor with IL-27 of fibroblast-like synoviocytes from RA had a suppressive effect on the production of proinflammatory cytokines in vitro. All these findings suggest that IL-27 may have promise as a potential therapeutic target for RA. In this review, we will discuss the biological features of IL-27 and summarize recent advances on both pathogenic and protective roles of IL-27 in RA.
24481092 Evaluation of Tp-e interval and Tp-e/QT ratio in patients with rheumatoid arthritis. 2014 Jan OBJECTIVES: Several studies have suggested that the interval from the peak to the end of the electrocardiographic T wave (Tp-e) may correspond to the transmural dispersion of repolarization and that increased Tp-e interval and Tp-e/QT ratio are associated with malignant ventricular arrhythmias. The aim of this study was to evaluate ventricular repolarization by using the Tp-e interval and Tp-e/QT ratio in patients with rheumatoid arthritis (RA), and to assess the relation with inflammation. STUDY DESIGN: Ninety-six patients (72 females, 24 males; mean age 43.8±11.8 years) with RA and 50 controls (35 females, 15 males; mean age 44.2±11.1 years) were included. From the 12-lead electrocardiogram, Tp-e interval and Tp-e/QT ratio were measured. Blood samples were taken for erythrocyte sedimentation rate (ESR) and plasma levels of C-reactive protein (CRP). These parameters were compared between groups. The relationship between ventricular repolarization and inflammation was assessed by Pearson correlation coefficients. RESULTS: Tp-e interval and Tp-e/QT ratio were increased in RA patients compared to the controls (72.6±8.2 vs 66.4±8.5 ms, 0.20±0.02 vs 0.18±0.02; p<0.001 and p<0.001, respectively). The Tp-e interval was significantly correlated with CRP, ESR, and disease activity score (DAS-28) (r=0.56, p<0.001, r=0.57, p<0.001, and r=0.29, p=0.02, respectively). The Tp-e/QT ratio was also correlated with CRP, ESR, and DAS-28 score (r=0.43, p<0.001, r=0.53, p<0.001, and r=0.25, p=0.03, respectively). CONCLUSION: In RA patients, the increased frequency of ventricular arrhythmias may be explained by increased indexes of ventricular repolarization and their relationship with inflammation.
23660425 Apolipoprotein m (APOM) levels and APOM rs805297 G/T polymorphism are associated with incr 2014 Jan OBJECTIVE: To examine whether the apolipoprotein M (APOM) rs805297 G/T polymorphism is associated with risk of rheumatoid arthritis (RA) in a Chinese population. METHODS: We studied APOM rs805297 G/T gene polymorphism in 520 RA patients, and 520 controls in a Chinese population. Genotyping was done by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. The blood plasma concentration of APOM was measured by an enzyme-linked immunosorbent assay in 84 RA patients and 84 controls. RESULTS: When the APOM rs805297 G/T GG homozygote genotype was used as the reference group, the TT or GT/TT genotype was associated with an increased risk for RA (TT vs. GG, adjusted odds ratio 1.76, 95% CI 1.11-2.77, P=0.016; GT + TT vs. GG, adjusted odds ratio 1.30, 95% CI 1.02-1.67, P=0.037). The average concentration of APOM in plasma was significantly higher in RA patients compared to controls. Stratification analysis found a significantly increased risk for RA associated with the APOM rs805297 TT genotype among male patients, C-reactive protein (CRP)-positive patients, anticitrullinated protein/peptide antibodies (ACPA) - positive patients, rheumatoid factor (RF) - positive patients, patients with higher levels of the erythrocyte sedimentation rate (ESR), patients with higher DAS28 score and patients with higher functional class compared to the APOM rs805297 GG genotype. CONCLUSION: These findings suggest that the functional single-nucleotide polymorphism APOM rs805297 G/T variant allele was associated with RA risk.
25365110 Remote collection of questionnaires. 2014 Sep Rheumatoid arthritis (RA) is an autoimmune inflammatory disease associated with rapid loss of function and radiographic damage. Treatment is targeted to achieve low disease activity/remission, as measured by various pooled indices comprised of laboratory measures, patient-derived, and physician-derived measures. Outside clinical trials, it can be difficult to obtain all these components at the time of the visit to provide immediate guidance. Subsequently, several pooled indices of patient reported outcomes (PROs) have been developed and shown to be equally and sometimes more effective as traditional assessor- and laboratory-derived measures in detecting treatment group and predicting long-term outcomes. With growing use of electronic medical record (EMR) and technology, many of these PROs can now be obtained remotely and directly incorporated into EMR to facilitate target to treat approach. Remotely collecting PROs through the internet allows better data capture, easier incorporation into EMR, and more frequent monitoring of patient's disease activity in between clinic visits for quicker assessment of adverse events and therapeutic efficacy. Adapting remotely collected PROs into clinical trials, clinical care, and long-term database has the potential for restructuring medical care while reducing costs and improving quality of care to achieve disease remission.
23553738 Brief report: rheumatoid arthritis is associated with left ventricular concentric remodeli 2013 Jul OBJECTIVE: To study left ventricular (LV) geometry in patients with rheumatoid arthritis (RA) and no history of heart failure compared with that in subjects with neither RA nor a history of heart failure, and to determine the impact of RA on LV remodeling. METHODS: A cross-sectional, community-based study was conducted among adult (age ≥50 years) patients with RA and age- and sex-matched subjects with neither RA nor a history of heart failure. All participants underwent standard 2-dimensional Doppler echocardiography. LV geometry was classified into the following 4 categories based on relative wall thickness and sex-specific cutoffs for the LV mass index: concentric remodeling, concentric hypertrophy, eccentric hypertrophy, or normal geometry. RESULTS: Among 200 patients with RA and 600 age- and sex-matched subjects without RA, the mean age was 65 years, and 74% of the individuals in both cohorts were female. Compared with subjects without RA, patients with RA were significantly more likely to have abnormal LV geometry (odds ratio [OR] 1.44, 95% confidence interval [95% CI] 1.03-2.00), even after adjusting for cardiovascular risk factors and comorbidities. Among subjects with abnormal LV geometry, the odds of concentric LV remodeling were significantly increased in patients with RA (OR 4.73, 95% CI 2.85-7.83). In linear regression analyses, the LV mass index appeared to be lower in patients with RA who were currently receiving corticosteroids (β ± SE -0.082 ± 0.027, P = 0.002), even after adjusting for cardiovascular risk factors and comorbidities. CONCLUSION: RA was strongly associated with abnormal LV remodeling (particularly concentric LV remodeling) among RA patients without heart failure. This association remained significant after adjustment for cardiovascular risk factors and comorbidities. RA disease-related factors may promote changes in LV geometry. The biologic mechanisms underlying LV remodeling warrant further investigation.
24315052 What is the best treatment strategy for early RA? 2013 Aug Treatment of early rheumatoid arthritis has to be started very early, when the diagnosis is made, preferentially before 6 months of symptoms. Combination therapy with conventional disease-modifying anti-rheumatic drugs (DMARDs) with low-dose, oral glucocorticoids in the induction phase from the start gives the best results. The patient should be monitored systematically, at start between 1 and 3 months, and the patient should have access to additional visits if a flare or arthritis or adverse event occurs. The treatment should aim to remission (no tender and swollen joints, no signs of inflammatory activity), which can be reached by 60-80% of the patients. Intra-articular glucocorticoid injections as part of the treatment strategy increase the suppression of arthritis and retard joint destruction. Biological drugs are reserved for patients who have consistent active disease and who do not respond to conventional combinations.
24125429 Cardiovascular risk in rheumatoid arthritis: how to lower the risk? 2013 Nov Patients with rheumatoid arthritis (RA) carry an excess risk for cardiovascular disease, which is comparable to the risk in patients with type 2 diabetes mellitus. The mechanisms involved are partly related to traditional cardiovascular risk factors, disease-associated inflammation and undertreatment of traditional cardiovascular disease (CVD) risk factors. Since atherosclerosis is an inflammatory disease, the auto-immune mediated inflammation observed in RA patients contributes to increased endothelial dysfunction, oxidative stress and activation and vascular migration of leukocytes. This concept is underscored by the CVD risk reduction that is seen by anti-inflammatory disease modifying anti-rheumatic drugs such as methotrexate and TNFα inhibitors. The evidence for underdiagnosis and undertreatment of traditional CVD risk factors in RA strengthens the potential benefit of structured CVD risk management in these patients. Current cardiovascular guidelines recommend screening and treatment of CVD risk factors in RA patients, without well defined treatment targets. At present, there is a lack of scientific evidence to establish treatment targets for CVD risk factors in RA. Therefore, expanding research regarding screening and treatment of traditional CVD risk factors in RA patients is needed.
24535368 [Coexisting rheumatoid arthritis and ankylosing spondylitis: 3 cases report]. 2014 Feb 18 OBJECTIVE: To understand the clinical profiles of coexisting rheumatoid arthritis (RA) and ankylosing spondylitis (AS). METHODS: Coexisting RA and AS was discussed with 3 cases, 108 similar cases were found in the literature and reviewed here. RESULTS: Coexisting RA and AS was rarely reported. The patients might have family histories of its related diseases, and initially present with diverse symptoms mainly in their youth. All the patients displayed severe symmetrical axial and peripheral arthritis. Joint destruction observed by imaging and the loss of functions were obvious. The prevalence of autoantibodies and HLA alleles was low. Most of the patients hardly demonstrated a good response to ordinary therapies. CONCLUSION: Patients with coexisting RA and AS present with various symptoms initially and have considerable joint dysfunction as well as unfavorable outcomes. They should receive aggressive therapeutic strategies.
23090655 The DAS28-ESR cutoff value necessary to achieve remission under the new Boolean-based remi 2013 Jan To seek the cutoff value of the 28-joint disease activity score using erythrocyte sedimentation rate (DAS28-ESR) that is necessary to achieve remission under the new Boolean-based criteria, we analyzed the data for 285 patients with rheumatoid arthritis registered between May 2008 and November 2009 by the Michinoku Tocilizumab Study Group and observed for 1 year after receiving tocilizumab (TCZ) in real clinical practice. Remission rates under the DAS28-ESR criteria and the Boolean criteria were assessed every 6 months after the first TCZ dose. The DAS28-ESR cutoff value necessary to achieve remission under the new criteria was analyzed by receiver operating characteristic (ROC) analysis. Data were analyzed using last observation carried forward. After 12 months of TCZ use, remission was achieved in 164 patients (57.5 %) by DAS28-ESR and 71 patients (24.9 %) under the new criteria for clinical trials. CRP levels scarcely affected remission rates, and the difference between remission rates defined by DAS28-ESR and by the new criteria was mainly due to patient global assessment (PGA). Improvement of PGA was inversely related to disease duration. ROC analysis revealed that the DAS28-ESR cutoff value necessary to predict remission under the new criteria for clinical trials was 1.54, with a sensitivity of 88.7 %, specificity of 85.5 %, positive predictive value of 67.0 %, and negative predictive value of 95.8 %. A DAS28-ESR cutoff value of 1.54 may be reasonable to predict achievement of remission under the new Boolean-based criteria for clinical trials in patients receiving TCZ.
25551928 Clinical and demographic findings of patients with rheumatoid arthritis and ankylosing spo 2014 BACKGROUND/AIM: Rheumatoid arthritis (RA) and ankylosing spondylitis (AS) are 2 common rheumatic diseases that are frequent causes of disability. In this descriptive study, demographic, clinical, and laboratory findings of patients with RA and AS being followed in a tertiary care center in Turkey were reported. MATERIALS AND METHODS: The patient data of 45 RA and 45 AS cases were collected retrospectively from electronic medical records. Demographic findings, clinical and laboratory assessments of disease activity, drugs used for the treatment, and effect on quality of life of patients with RA and AS were analyzed. RESULTS: In RA patients, 27% had mild, 44% had moderate, and 29% had severe disease and 25% of the patients had satisfactory functional state. In AS patients, the mean Bath Ankylosing Spondylitis Disease Activity Index score was 4.6 ± 2.3 and 64% had active disease. Sixteen percent of the patients with AS reported satisfactory functional state. In RA cases, the highest percentage of patients were treated with biological agents. In AS cases, 24% of patients were treated with NSAIDs and 22% received biological agents. CONCLUSION: In our tertiary care center, the majority of patients with RA and AS had active disease with unsatisfactory functional states.
23772583 Copper levels in patients with rheumatoid arthritis. 2013 INTRODUCTION: Rheumatoid arthritis (RA) is a chronic, autoimmune-based disease of the connective tissue with still unknown etiology. Numerous studies have indicated the association between Copper (Cu) and ceruloplasmin (Cp) concentrations and pathogenesis of RA. OBJECTIVE: To compare the concentrations of Cu and Cp in different biological samples and their correlation with the inflammatory process, between a group of patients with RA and a control group of healthy individuals. MATERIALS AND METHODS: The study enrolled 74 Caucasian patients (20 men and 54 women), aged 29-50 (mean age 39.8±6.1 years) diagnosed with RA. The control group consisted of 30 healthy Caucasian individuals. Copper levels were assessed by atomic absorption spectroscopy. RESULTS: Among RA patients the mean Cu level was significantly higher in serum and hair compartments and significantly lower in erythrocytes, compared with the control group (p<0.01). The Cp concentration was also higher in serum of RA patients (p<0.001). A statistically significant, positive correlation between the Cp serum concentration and the ESR values (r(s)=0.38; p<0.007) was found. No significant influence of pharmaceutical treatment (methotrexate, non-steroidal anti-inflammatory drugs, glucocorticoids, calcium, vitamin D3 and sulphasalazine) on serum Cu was found. CONCLUSIONS: It seems that the 'copper status' in patients with RA, based on the measurement of Cu and Cp levels in blood serum is correlated with presence of the inflammatory process. The hair could serve as a useful, additional diagnostic material. Some other factors, different from the applied treatment, can probably influence the Cu levels in patients with RA.
22972604 Tibialis posterior tenosynovitis and associated pes plano valgus in rheumatoid arthritis: 2013 Apr OBJECTIVE: To compare electromyographic (EMG), kinematic, kinetic, and ultrasound (US) features of pes plano valgus associated with US-confirmed tibialis posterior (TP) tenosynovitis in rheumatoid arthritis (RA) and healthy control subjects. METHODS: In this cross-sectional study, patients with RA and US-confirmed tenosynovitis of TP underwent gait analysis, including 3-dimensional kinematics, kinetics, and intramuscular EMG of TP, and findings were compared with a group of healthy individuals. The RA group also underwent B mode and power Doppler US scanning of the TP tendon to assess and score levels of pathology. RESULTS: Ten patients with RA, median (range) disease duration of 3 years (1-18 years), and 5 control subjects were recruited. Compared to control subjects, the RA patients walked slower and presented with moderate levels of foot-related disability. The mean ± SD Disease Activity Score in 28 joints was 4.6 ± 1.6. Increased magnitude of TP activity was recorded in the RA group compared to controls in the contact period of stance (P = 0.007), in conjunction with reduced ankle joint power (P = 0.005), reduced navicular height in the medial arch (P = 0.023), and increased forefoot dorsiflexion (P = 0.027). TP tendon thickening, fluid, and power Doppler signal were observed in the majority of patients. CONCLUSION: This study has demonstrated, for the first time, increased TP EMG activity in the presence of US-confirmed TP tenosynovitis in RA. Altered muscle function occurred in conjunction with suboptimal mechanics, moderate levels of tendon pathology, and active disease. Targeted therapy may be warranted to reduce inflammation and mechanically off-load diseased tendon states.
23881438 The relationship between disease activity and depressive symptoms severity and optimism--r 2013 Dec To assess depressive symptoms severity and dispositional optimism in patients with recent onset arthritis both before and after 4 months treatment. Two hundred twenty-two patients with recent onset RA and undifferentiated arthritis in the IMPROVED study filled out the Beck Depression Inventory (BDI-II) to assess depressive symptoms severity and the Life Orientation Test Revised (LOT-R) to measure optimism before and after 4 months of treatment. All patients were treated with methotrexate 25 mg/week and prednisone 60 mg/day (tapered to 7.5 mg/day in 7 weeks). Linear regression analysis was used to assess the association between the disease activity score (DAS) and its components (tender joint count, general well-being measured with a visual analogue scale (VAS), swollen joint count, and erythrocyte sedimentation rate) with the BDI-II an LOT-R scores. In general, depressive symptoms were mild. The DAS was an independent predictor of depressive symptoms scores both at baseline and after 4 months follow-up, in particular tender joint count and VAS global health. Disease activity was not associated with the level of optimism. Nevertheless, patients who achieved clinical remission improved significantly more in both depression score and optimism score than patients who did not. Patients with early arthritis report improvement in depressive symptoms and optimism with improvement in disease activity and achieving clinical remission. Depression scores are associated with pain and unwell being but not with swollen joint counts and inflammatory parameters.
23497830 Gender-specific association between childhood trauma and rheumatoid arthritis: a case-cont 2013 Apr OBJECTIVE: Rheumatoid arthritis (RA) has been associated with a variety of emotional stressors, but findings remain inconclusive if RA is related to childhood trauma, which is known to have long-lasting negative consequences for physical health decades into adulthood. We investigated the association between childhood trauma and RA by comparing histories of child abuse and neglect between RA patients and adults from the general population in a cross-sectional case-control study. METHODS: 331 patients with definite RA and 662 gender- and age-matched adults from the general population were administered the self-report Childhood Trauma Questionnaire (CTQ) for the assessment of emotional, physical and sexual abuse as well as emotional and physical neglect. RESULTS: Adjusting for gender and current depression, RA patients scored significantly higher in all CTQ subscales apart from sexual abuse and physical neglect than the controls. Adjusted odds ratios for these types of childhood trauma were higher in the RA group than in controls ranging from 2.0 for emotional neglect (95% confidence interval [CI]: 1.4-3.0) to 2.6 for emotional abuse (95% CI: 1.4-4.7). Gender-specific analyses revealed basically the same pattern for women, but not for men. CONCLUSION: Our findings suggest an association between childhood trauma and development of RA, particularly in women. This relationship may be mediated by dysregulations of neuro-endocrine-immune networks, but larger prospective studies are needed to clarify the association between early life stress and the risk for RA in genetically susceptible individuals.
