27117699 The association between anti-carbamylated protein (anti-CarP) antibodies and radiographic 2017 Jan OBJECTIVE: Anti-carbamylated protein (anti-CarP) antibodies are reported to associate with more radiographic progression within the total rheumatoid arthritis (RA) population and anti-citrullinated peptide antibody (ACPA)-negative subgroup. We explored the association of anti-CarP with radiographic progression in RA and aimed to replicate the association and evaluate the added value of anti-CarP antibodies in relation to ACPA and rheumatoid factor (RF). METHODS: 576 Swedish and 628 Dutch patients with RA (2394 and 3247 sets of radiographs, respectively) were longitudinally studied. Replication was restricted to the Swedish patients. In both cohorts, the association of anti-CarP with radiographic progression was determined in strata of patients with similar ACPA and RF status; results of both cohorts were combined in fixed-effect meta-analyses. The net percentage of patients for whom the radiographic progression in 5 years was additionally correctly classified when adding anti-CarP to a model including ACPA and RF was evaluated. RESULTS: Anti-CarP associated with radiographic progression in the total Swedish RA population (beta=1.11 per year, p=8.75×10(-13)) and in the ACPA-negative subgroup (beta=1.14 per year, p=0.034). Anti-CarP associated with more radiographic progression in the strata of ACPA-positive/RF-negative, ACPA-negative/RF-positive and ACPA-positive/RF-positive patients with RA (respective p values 0.014, 0.019 and 0.0056). A model including ACPA and RF correctly classified 54% and 57% of the patients; adding anti-CarP to this model did not increase these percentages (54% and 56% were correctly classified). CONCLUSIONS: Anti-CarP antibodies associated with more severe radiographic progression in the total and ACPA-negative RA population. Anti-CarP-positivity had a statistically significant additive value to ACPA and RF, but did not improve correct classification of patients.
27166684 The Impact of Conventional and Biological Disease Modifying Antirheumatic Drugs on Bone Bi 2016 Aug The bone and the immune system have a very tight interaction. Systemic immune-mediated inflammatory diseases, such as rheumatoid arthritis (RA), induce bone loss, leading to a twofold increase in osteoporosis and an increase of fragility fracture risk of 1.35-2.13 times. This review focuses on the effects of conventional and biological disease modifying antirheumatic drugs (DMARDs) on bone biology, in the context of systemic inflammation, with a focus on RA. Published evidence supports a decrease in osteoclastic activity induced by DMARDs, which leads to positive effects on bone mineral density (BMD). It is unknown if this effect could be translated into fracture risk reduction. The combination with antiosteoclastic drugs can have an additional benefit.
27146242 A novel method predicting clinical response using only background clinical data in RA pati 2016 Nov OBJECTIVES: The aim of the present study was to generate a novel method for predicting the clinical response to infliximab (IFX), using a machine-learning algorithm with only clinical data obtained before the treatment in rheumatoid arthritis (RA) patients. METHODS: We obtained 32 variables out of the clinical data on the patients from two independent hospitals. Next, we selected both clinical parameters and machine-learning algorithms and decided the candidates of prediction method. These candidates were verified by clinical variables on different patients from two other hospitals. Finally, we decided the prediction method to achieve the highest score. RESULTS: The combination of multilayer perceptron algorithm (neural network) and nine clinical parameters shows the best accuracy performance. This method could predict the good or moderate response to IFX with 92% accuracy. The sensitivity of this method was 96.7%, while the specificity was 75%. CONCLUSIONS: We have developed a novel method for predicting the clinical response using only background clinical data in RA patients before treatment with IFX. Our method for predicting the response to IFX in RA patients may have advantages over the other previous methods in several points including easy usability, cost-effectiveness and accuracy.
27149946 Pixel-by-Pixel Arterial Spin Labeling Blood Flow Pattern Variation Analysis for Discrimina 2017 Jan 10 We examined the capability of a gray-scale arterial spin labeling blood flow pattern variation (BFPV) map with two different post labeling delay (PLD) times to discriminate pannus in patients with rheumatoid arthritis (RA) at 3T. There was a statistically significant difference in the BFPV values between artery, pannus, and surrounding tissue. Furthermore, the color-coded BFPV map was able to accurately distinguish pannus from other tissues. These results suggest this approach may be capable of identifying pannus noninvasively.
25772173 Metalloproteinases: potential therapeutic targets for rheumatoid arthritis. 2015 In different inflammatory diseases, many metalloproteinases are over expressed and thought to promote progression of the disease. Understanding roles of these enzymes in disease progression as well as in normal homeostasis is crucial to identify target enzymes for the disease. Rheumatoid arthritis (RA) is one of the autoimmune inflammatory diseases in which around 1-2 % of the world populations are suffered from. Roles of metalloproteinases are well documented in RA, but so far none of them is proposed to be a target enzyme. However, there are at least three enzymes that can potentially be molecular targets to inhibit progression of RA. Understanding roles of these enzymes in more detail and developing highly selective inhibitors to these enzymes would be essential for novel antimetalloproteinase therapies in future.
26680365 [Clinical remission in rheumatoid arthritis. Data from the early arthritis cohort study CA 2016 Feb OBJECTIVE: To evaluate remission rates and therapeutic strategies in the routine care of early rheumatoid arthritis. METHODS: Between 2010 and 2013, a total of 1,301 patients with early arthritis were followed by 89 rheumatologists for up to 2 years in an early arthritis cohort (CAPEA). Complete 2-year data are available for 669 patients with rheumatoid arthritis. RESULTS: Ninety-three percent of patients were diagnosed with a moderate or high disease activity score (DAS28 > 3.2). Within 6 months, 40 % were in clinical remission (DAS28 < 2.6) and 21 % reached a low disease activity score (DAS28 > 2.6 to < 3.2). This proportion did not substantially increase during the 2-year follow-up. Methotrexate was the standard first-line treatment in 82 % of patients. During follow-up, 10 % were treated with a combination of disease-modifying antirheumatic drugs (DMARDs) and 12 % with biological agents. In 60 % of the patients who did not reach remission within 3 months (and 54 % of patients without remission by 6 months), treatment was not changed. At the beginning, 77 % of patients were treated with glucocorticoids at different starting doses (26 % < 7.5 mg, 29 % 7.5-20 mg, and 45 % ≥ 20 mg of prednisolone per day). After 2 years, 47 % remained on glucocorticoids. CONCLUSION: While 40 % of patients achieved clinical remission through standard care within 6 months, disease activity remained moderate to high in 37 % of patients at 2 years. In these patients a more consistent application of treatment may have increased the response rates.
27126784 Lack of tumor necrosis factor alpha gene polymorphism -857c/t (rs1799724) association in P 2016 Nov BACKGROUND: Rheumatoid arthritis (RA) is a common systemic autoimmune disease, influenced greatly by the pro-inflammatory cytokine tumor necrosis factor- alpha (TNF-α). Single nucleotide polymorphisms (SNPs) in regulatory regions of the TNF-α gene play a significant role in disease development and pathogenesis. The aim of this study was to investigate the association of TNF-α -857C/T (rs1799724) SNP with RA activity or severity in our Pakistani study group. METHODS: The study included 134 (116 women, 18 men) patients with RA and 134 ethnically matched healthy controls (108 women, 26 men). Each patient's disease activity was measured by Disease Activity Score of 28 joints. The genotypes were determined in all included individuals following allele-specific polymerase chain reaction along with the prerequisite internal amplification controls. Statistical analysis including chi-square/Fischer exact test and one-way analysis of variance; nonparametric Kruskal-Wallis test was employed using Graphpad Prism 6 software for association study. RESULTS: The prevalence of TNF-α -857C/T (rs1799724) polymorphism was not differentially distributed between RA patients and controls in either allele frequency, with odds ratio (95% CI) of 0.9661 (0.6714-1.390) and P-value of 0.8527, or genotype frequency with χ(2) of 0.5015 and P-value of 0.7782. Moreover, no correlation was found when genotype frequency distribution was analyzed with disease severity (P = 0.6321 and Kruskal-Wallis statistics of 1.098). CONCLUSION: The study demonstrated -857C/T (rs1799724) polymorphism may not have influenced RA susceptibility in our study group. However, investigations of genetic variability influence on disease outcome in large prospective cohorts are required, so the complicated interconnection of genetic and environmental elements can be emulated for better understanding.
27032396 Hypoxia-Inducible Factor-1α and Autoimmune Lupus, Arthritis. 2016 Jun Hypoxia elicits an orchestrated response in cells, tissues, and entire organisms to survive a hypoxic challenge. On a molecular level, this response can be controlled by oxygen-dependent stabilization of the transcription factor hypoxia-inducible factor (HIF)-1α. Recently, studies have shown that HIF-1α plays an important role in the development and function of T helper (Th) cells, regulatory T (Treg) cells, and dendritic cells (DCs). Because these cells are critical in the pathogenesis of autoimmune diseases, such as systemic lupus erythematosus and rheumatoid arthritis, the roles of HIF-1α in these autoimmune disorders cannot be neglected. In this review, we discuss recent findings on the important roles of HIF-1α in immune cells and the possible pathologic roles of HIF-1α in autoimmune diseases. The obtained information may lead to deeper insights into the roles of HIF-1α in these disorders.
27154592 Clinical profile and outcome of patients with rheumatoid arthritis and abnormally high aor 2016 Nov OBJECTIVES: Ascending aorta has an increased stiffness (AoSI) in rheumatoid arthritis (RA) patients due to their chronic inflammatory status. We assessed prevalence and factors associated with increased AoSI and its prognostic role in a large cohort of RA patients. METHODS: We prospectively analysed 226 RA patients without overt cardiac disease compared with 226 non-RA patients matched for cardiovascular risk factors (non-RA controls). Abnormally high AoSI was diagnosed if AoSI > 6.07% (95th percentile of the AoSI detected in our reference healthy population). AoSI was assessed at the level of the aortic root by two-dimensional guided M-mode evaluation as part of a thorough echocardiography performed in all patients. RESULTS: AoSI was significantly higher in the RA patients than non-RA controls (6.3 ± 4.5% vs. 4.6 ± 3.5%, p < 0.001); it was related to older age, higher systolic blood pressure and RA disease. Predictors of AoSI in RA patients were older age, higher systolic blood pressure and the non-prescription of non-steroidal anti-inflammatory drug and/or immunomodulatory/anti-cytotoxic agents. Abnormally high AoSI was diagnosed in 41% RA patients and 21% non-RA controls (p < 0.001). The RA phenotype with abnormally high AoSI was a > 60 years old subject with systolic blood pressure > 129 mmHg, mitral annular calcification who was not receiving non-steroidal anti-inflammatory drug. By multivariate Cox regression analysis abnormally high AoSI independently predicted death or all-cause hospitalization (hazard ratio 2.85 (95% confidence interval 1.03-7.85)) at 12-month follow-up. CONCLUSIONS: Increased AoSI is common, can be predicted by an ordinary clinical assessment and is a strong predictor of adverse clinical outcome at mid-term follow-up in patients with RA.
27558077 Increased healthcare resource utilization in higher disease activity levels in initiators 2016 Dec OBJECTIVE: Determine healthcare resource utilization (HCRU) in biologic-naïve initiators of TNF inhibitors (TNFis) associated with their disease activity from a national cohort of rheumatoid arthritis (RA) patients. METHODS: RA patients were identified at their first TNFi initiation (index date) in the Corrona registry. Patients with age of RA onset <18, comorbid psoriasis/psoriatic arthritis, fibromyalgia, or osteoarthritis were excluded. Patients were categorized into disease activity (DA) strata by the lowest level of DA (and sustaining low levels for at least two visits) using the Clinical Disease Activity Index (CDAI) across all visits in Corrona while on a TNFi during 1 year after initiation. Rates of all-cause and RA-related hospitalizations, rheumatologist visits, and joint surgeries while on TNFi therapy were reported and compared across DA levels along with the incidence rate ratio (IRR) adjusted for age, gender, and RA duration using Poisson mixed models. RESULTS: Of 1931 RA patients: 15% achieved sustained remission, 22% remission, 14% sustained low DA, 23% low DA and 27% moderate/high DA (M/HDA). Those in M/HDA had statistically higher rates of hospitalizations (37.3 per 100 patient years (py), 95% CI: 31.6-43.7 and joint surgeries (20.8 per 100 py, 95% CI: 16.6-25.8) compared to the sustained remission cohort, resulting in respective IRRs of 2.3 (p < 0.001) and 1.7 (p = 0.046). CONCLUSION: Many biologic naïve RA patients initiating TNFi failed to achieve sustained remission during a 1 year period while remaining on TNFi therapy. Patients in higher DA levels had higher HCRU rates vs. patients in sustained remission, suggesting that achieving treat-to-target goals would reduce health care expenses.
24889289 The development and initial validation of a questionnaire to measure help-seeking behaviou 2015 Dec BACKGROUND: Early treatment for rheumatoid arthritis (RA) is vital. However, people often delay in seeking help at symptom onset. An assessment of the reasons behind patient delay is necessary to develop interventions to promote rapid consultation. OBJECTIVE: Using a mixed methods design, we aimed to develop and test a questionnaire to assess the barriers to help seeking at RA onset. DESIGN: Questionnaire items were extracted from previous qualitative studies. Fifteen people with a lived experience of arthritis participated in focus groups to enhance the questionnaire's face validity. The questionnaire was also reviewed by groups of multidisciplinary health-care professionals. A test-retest survey of 41 patients with newly presenting RA or unclassified arthritis assessed the questionnaire items' intraclass correlations. RESULTS: During focus groups, participants rephrased questions, added questions and deleted items not relevant to the questionnaire's aims. Participants organized items into themes: early symptom experience, initial reactions to symptoms, self-management behaviours, causal beliefs, involvement of significant others, pre-diagnosis knowledge about RA, direct barriers to seeking help and relationship with GP. The test-retest survey identified seven items (out of 79) with low intraclass correlations which were removed from the final questionnaire. CONCLUSION: The involvement of people with a lived experience of arthritis and multidisciplinary health-care professionals in the preliminary validation of the DELAY (delays in evaluating arthritis early) questionnaire has enriched its development. Preliminary assessment established its reliability. The DELAY questionnaire provides a tool for researchers to evaluate individual, cultural and health service barriers to help-seeking behaviour at RA onset.
26724524 Vitamin D receptor GATG haplotype association with atherosclerotic disease in patients wit 2016 Feb INTRODUCTION: An association between the vitamin D receptor (VDR) GAT haplotype and coronary artery disease (CAD) in type-2 diabetes has recently been described. Since cardiovascular mortality in rheumatoid arthritis (RA) is comparable to that observed for patients with type-2 diabetes, we aimed to determine if VDR GAT haplotype is also associated with atherosclerotic disease in RA. MATERIAL AND METHODS: 591 Northern Spanish RA patients were genotyped for 4 VDR polymorphisms (rs731236 A/G; rs7975232 A/C; rs1544410C/T; rs2228570 G/A). Atherosclerotic disease was established by the presence of carotid plaques in carotid ultrasound. RESULTS: VDR rs7975232 AA genotype was increased in RA patients with plaques (p = 0.045, OR = 1.46 [1.01-2.18]). More importantly, the frequency of carotid plaques was significantly increased in RA patients who carried the GATG haplotype (p = 0.009, OR = 1.56 [1.09-2.42]). CONCLUSION: Our results suggest a potential VDR GATG haplotype association with atherosclerotic disease in RA patients.
25823782 FCGR polymorphisms in the treatment of rheumatoid arthritis with Fc-containing TNF inhibit 2015 OBJECTIVES: Reproducible association of a functional polymorphism in FCGR2A with response to a TNF inhibitor (TNFi) in patients with rheumatoid arthritis (RA) led us to explore other FcγR functional polymorphisms. METHODS: Functional polymorphisms FCGR3A F158V, FCGR2B I223T and promoter VNTR in FCGRT were analyzed in up to 429 patients with RA. Response to TNFi was recorded during standard care at 3, 6 and 12 months of follow-up. Fixed effects meta-analysis of studies addressing FCGR3A F158V polymorphism, which is the most studied of these polymorphisms, was conducted with inverse variance weighting. RESULTS: None of the functional polymorphisms were associated with change in DAS28. Meta-analysis of the seven studies (899 patients) with available data addressing association of FCGR3A F158V with response to TNFi in RA showed no association (OR: 1.11, 95% CI: 0.8-1.5; p = 0.5). CONCLUSION: None of the three functional polymorphisms in FcγR genes showed association with response to TNFi in patients with RA. These negative results were obtained in spite of the larger size of this study relative to previous studies addressing the same polymorphisms. In addition, meta-analysis of FCGR3A F158V was also negative against the results provided by previous studies. Original submitted 17 September 2014; Revision submitted 9 December 2014.
25565419 Risk factors for herpes zoster in rheumatoid arthritis patients: the role of tumour necros 2015 Mar AIM: To determine whether exposure to tumour necrosis factor (TNF)-α inhibitors increases the risk of herpes zoster (HZ) among people with rheumatoid arthritis (RA). METHODS: We performed a cohort study of people with RA participating in the Australian Rheumatology Association Database. We identified self-reported cases of HZ and verified using medical records. For the primary analysis, we only included doctor-verified cases. For TNF-α inhibitor exposed groups, we excluded HZ episodes that occurred before TNF-α inhibitor initiation, and for the control group we excluded HZ episodes that occurred prior to 2000 or RA diagnosis. The risk of HZ among participants exposed versus not exposed to TNF-α inhibitors was compared using Cox proportional hazards models including significant covariates affecting the risk. Adjusted hazard ratios (HR) were calculated for TNF inhibitors as a class and for individual agents. RESULTS: Among 2157 active RA participants, there were 442 self-reported cases of HZ. From 346 responses from doctors, 249 cases were verified and four were false positives (false positive rate 1.6%). Crude incidence of verified HZ in the entire RA cohort was 15.9/1000 person-years (95% confidence interval (CI): 13.5-18.8). An increased risk of HZ was found for all TNF-α inhibitors combined (fully adjusted HR 1.71; 95% CI: 1.00-2.92) and adalimumab (fully adjusted HR 2.33; 95% CI: 1.22-4.45), but in the fully adjusted model was not increased with etanercept (fully adjusted HR 1.65; 95% CI: 0.90-3.03). No increased risk was found with infliximab (HR 1.29; 95% CI: 0.37-4.47). CONCLUSIONS: TNF-α inhibitors are associated with an increased risk of HZ in people with RA compared with those who have not been exposed.
26913787 The synovial grade corresponding to clinically involved joints and a feasible ultrasound-a 2016 Nov OBJECTIVES: To determine which grade of ultrasound (US) synovitis corresponds to clinically involved joints in rheumatoid arthritis (RA) and develops a new US-adjusted composite measure. METHODS: Clinical and US examinations were performed on 137 patients with RA (28 joints). Synovial effusion, hypertrophy, and blood flow were semiquantitatively graded from 0 to 3 using gray scale (GS) and power Doppler (PD) modes. We calculated US-adjusted simple disease activity index (SDAI) and assessed feasibility, and external validity by comparing with erythrocyte sedimentation rate (ESR), and modified health assessment questionnaires (MHAQ). RESULTS: GS ≥2 and PD ≥0 corresponds to clinically swollen joints, and GS ≥2 and PD ≥1 corresponds to tender joints. The US-adjusted SDAI showed the highest correlation when US-determined swollen joints were defined as PD ≥2 with ESR, and GS ≥3 and PD ≥2 with MHAQ. A feasible US-adjusted SDAI examining only clinically involved joints still showed a higher correlation with ESR and MHAQ than SDAI. CONCLUSION: Our composite measure complemented by US only for clinically involved joints is feasible and reliable for monitoring disease activity.
27476621 Overlap between systemic sclerosis and rheumatoid arthritis: a distinct clinical entity? 2016 Jul INTRODUCTION: Systemic sclerosis (SSc) is an autoimmune disease of the connective tissue characterized by the triad of vascular injury, autoimmunity (cellular and humoral) and tissue fibrosis. It is estimated that musculoskeletal pain is a common complaint of patients with SSc, ranging from 40 to 80%, and mainly in patients with early diffuse disease. Arthritis, clinically observed, may be a feature seen in the presentation of SSc, often leading to early diagnostic errors with rheumatoid arthritis (RA). In the course of the disease, arthritis is observed in 24-97% of patients with SSc. OBJECTIVES: To correlate the occurrence or nonoccurrence of arthritis in patients with SSc of the Midwest region of Brazil with possible distinct clinical and laboratory manifestations observed in three groups of patients. To report the frequency of true association between systemic sclerosis and rheumatoid arthritis in patients with clinically and radiologically observed synovitis. METHODS: Sixty-one SSc patients were subsequently assessed every 3 months within 1 year, in order to clinically observe the occurrence of synovitis and its patterns of progression. Patients were divided into 3 groups: 41 patients with SSc without arthritis, 16 SSc patients with arthritis and 4 patients with overlap of SSc and RA. All patients underwent a radiological examination of the hands at the end of the study. RESULTS: Among all patients evaluated, we found a female predominance (98.7%), mean age of 50.94 years, white color (49.2%), limited form of the disease (47.6%), time of diagnosis between 5 and 10 years (47.6%) and duration of the disease of 8.30 years. Among all patients, 14 (22.9%) had positive rheumatoid factor (RF), while among those with positive RF, only 10 patients had arthritis during one-year follow-up. The antibody anticitrulline (anti-CCP) test was performed in 24 patients, being positive in 4 of them (16.7%), with positivity being observed only in patients with SSc/RA overlap. Comparing the clinical manifestations among the groups of patients, there was a higher incidence of gastritis and cardiac valvulopathy in patients with SSc and arthritis, but not in the others. In the group of patients with SSc/RA overlap and in patients with SSc and arthritis a significant reduction in quality of life was observed, measured by HAQ index, especially in patients with arthritis present during clinical evaluation. We found radiographic changes in 42.6% of patients with SSc. However, in patients with synovitis, radiological changes consistent with rheumatoid arthritis were found in 50% of patients. CONCLUSIONS: While the frequency of clinical arthritis observed in patients with systemic sclerosis was 32.8%, the true overlap between of SSc and RA was 6.6% in this study. We also observed the frequency of positive anti-CCP in 20% of patients with arthritis versus no patients with SSc without arthritis.
27181129 Evaluation of the effect of acupuncture on hand pain, functional deficits and health-relat 2016 May BACKGROUND: Rheumatoid arthritis (RA) is a systemic inflammatory disease characterized by functional disability and pain. Although acupuncture is widely used, until now Western acupuncture studies on RA have not shown conclusive positive results. Acupuncture is regarded as a reflex therapy that has effects on the human autonomic nervous system. By establishing a traditional Chinese medicine (TCM) diagnosis first, the practitioner is able to choose acupoints according to the state of each individual patient. METHODS/DESIGN: We are interested if acupuncture, using a classical diagnostic procedure to allocate acupoints to the patient according to the Shang Han Lun theory, can be effective in relieving pain, improving hand function and increasing health-related quality of life in RA.The authors intend to harmonize TCM diagnosis according to clinical and genetic profiles. Patients with the TCM diagnosis of a so-called Turning Point syndrome will be followed up in a randomized, prospective, double-blind, placebo-controlled, multicenter and three-armed parallel-group study with a standardized treatment in order to optimize potential therapeutic effects of acupuncture on pain, strength and muscle function of patients with RA as well as the influence on inflammation and quality of life. DISCUSSION: The findings of this study will provide important clinical information about the feasibility and efficacy of acupuncture treatment for RA patients. In addition, it will explore the feasibility of further acupuncture research. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Identifier NCT02553005.
26591677 Efficacy and safety of Xinfeng capsule in patients with rheumatoid arthritis: a multi-cent 2015 Oct OBJECTIVE: To evaluate the efficacy. and safety of Xinfeng capsule in patients suffering rheumatoid arthritis (RA). METHODS: A multi-center parallel-group designed, double-blind, randomized, controlled trial was conducted. Totally 304 RA patients were assigned to two groups: one group was administered Xinfeng capsule (XFC) plus the placebo of leflunomide and the other given leflunomide (LEF) plus the placebo of XFC for twelve weeks. The clinical and laboratory parameters were compared at baseline and fourth, eighth, and twelfth weeks. RESULTS: After twelve-week treatment, patients in two groups all showed some trend of effectiveness when compared in terms of American Rheumatism Association (ACR) recommended 20%, 50%, 70% improvement criteria, but it was insignificant. The validity in ameliorate modified disease activity score (DAS28) and laboratory indexes as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor (RF) were also found no difference. The score of health assessment questionnaire (HAQ), self-rating anxiety scale (SAS), self-rating depression scale (SDS) and quality of life questionnaire with rheumatoid arthritis (RAQOL) both lower than the first week and the changes showed no difference. However, the score of SDS dropped more in XFC group than in the other. A total of 147 adverse reaction cases were reported, which shows no difference between the two groups. The most common adverse reactions were hepatic impairment, anemia, leukocytopenia, epigastric discomfort and phalacrosis. CONCLUSION: XFC demonstrated better improvement in the scores of SDS and compared with those of LEF group.
27538585 Meta-analysis of long-term joint structural deterioration in minimally treated patients wi 2016 Aug 18 BACKGROUND: Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by inflammation and joint structural deterioration. Driven by recent expectations that patients in clinical trials randomized to placebo should be 'rescued' with active therapy within 6 months of starting treatment, the relative benefit of arresting joint damage with biologic agents beyond this period is unclear. With longer-term evidence of the rate of joint deterioration with minimal treatment, the efficacy of biologic agents and novel treatments might be projected beyond the placebo-controlled phase observed in clinical trials. The aim of this study was to estimate radiographic structural deterioration over time in patients with moderate-to-severe RA minimally treated with DMARDs. METHODS: A literature review identified evidence of joint structural deterioration in patients with (DMARD-IR population) and without (non-DMARD-IR population) a history of inadequate response to DMARDs. Patients were minimally treated with one non-biologic DMARD or palliative care (non-DMARD-IR population only). Outcomes of interest were the (modified) Total Sharp Score (TSS) and subscales (Erosion Subscore [ES] and Joint Space Narrowing [JSN] Subscore), and Larsen score. Pooled joint-deterioration curves over time were obtained with meta-analysis models. RESULTS: Mean change from baseline in TSS increased in the DMARD-IR population from 1.14 (95 % credible interval [CrI] 0.66, 1.67) to 9.84 (5.68, 14.46) at Weeks 12 and 104, respectively, and a non-linear increase of 1.56 (0.79, 2.34) and 5.13 (-1.35, 11.67) in the non-DMARD-IR population. At the same time points, mean changes (95 % CrI) were 0.51 (0.27, 0.83) and 4.43 (2.38, 7.21) for ES and 0.36 (0.09, 0.67) and 3.14 (0.80, 5.78) for JSN in the DMARD-IR population, whereas corresponding changes in the non-DMARD-IR population were 0.69 (0.31, 1.12) and 2.93 (0.92, 5.02), and 0.29 (0.17, 0.44) and 2.55 (1.45, 3.80), respectively. Larsen scores were only available for the non-DMARD-IR population, with mean changes (95 % CrI) of 0.08 (0.04, 0.11) and 0.65 (0.36, 0.96) at Weeks 12 and 104, respectively. CONCLUSION: Minimal treatment of RA with one non-biologic DMARD results in deterioration of joint structure in patients with or without a history of inadequate response to non-biologic DMARDs.
25619283 Chronological changes in baseline disease activity of patients with rheumatoid arthritis w 2015 May BACKGROUND/PURPOSE: The use of biologic disease-modifying anti-rheumatic drugs (DMARDs) for rheumatoid arthritis (RA) has been increasing since 2003. In this study, we evaluated changes in the characteristics of patients receiving biologic DMARDs daily, in Japan. METHODS: The characteristics of all RA patients who received any biologic DMARD at the Institute of Rheumatology, Tokyo Women's Medical University, within 1 year after its approval in Japan, were retrospectively evaluated. The periods of patient enrollment for each biologic agent were: infliximab (IFX), 2003-2004; etanercept (ETN), 2005-2006; tocilizumab (TCZ), 2008-2009; adalimumab (ADA), 2008-2009; abatacept (ABT), 2010-2011; and golimumab (GLM), 2011-2012. We retrospectively collected individual patient characteristics, concomitant medication usage, and disease activity assessed by disease activity score 28 (DAS28) at the time of administration, from the medical records. The retention rate for each agent at 6 months after treatment initiation was also assessed. RESULTS: The numbers of patients who received each biologic DMARD at our institute within 1 year after its approval were: IFX, 49; ETN, 50; TCZ, 62; ADA, 52; ABT, 40; and GLM, 77. From 2003 to 2012, the proportion of patients with prior use of any biologic DMARD increased, as did concomitant use and dose of methotrexate (MTX); however, corticosteroid use and doses decreased. DAS28, at the time of treatment initiation, gradually decreased. At the time of IFX administration, 75% and 25% of patients had high and moderate disease activity respectively, compared to 25% and 58% respectively, of patients who received GLM. No significant difference was observed in the retention rate of biologic DMARDs at 6 months (range, 75.0% to 89.6%). CONCLUSION: Baseline disease activity of RA patients who received biologic DMARDs between 2003 and 2012 has changed from high to moderate in daily practice in Japan.
