27770044 Methotrexate impact on radiographic progression in biologic-treated rheumatoid arthritis u 2016 Dec We describe Caucasian monozygotic twin brothers with rheumatoid arthritis (RA) and discuss influence of predictors to methotrexate (MTX) outcome treatment. Single nucleotide polymorphisms (SNPs) of the MTX metabolic pathways were genotyped. Twins have multiple mutations: a CC mutation of SNP 1298A>C in methylenetetrahydrofolate reductase (MTHFR) gene, CC mutations of three SNPs in the adenosine receptor gene ADORA2A (rs3761422_4217241T>C, rs2267076_4221164T>C, rs2236624_4226593T>C), and a heterozygous genotype in SNPs ATIC_rs2372536_347C>G, MTHFD1_rs2236225_1958G>A. These mutations are known to predict a worse outcome of MTX treatment. The twins had different lifestyles (alcohol drinking and smoking in Twin 1, regular coffee consumption in Twin 2), but a very similar clinical presentation of the outset of RA, radiographic scoring according to the Sharp/van der Heijde method with an almost identical antibodies presentation. The period of the patients before anti-TNFα treatment was characterized by unsuccessful per oral MTX pharmacotherapy in both cases (a low effect of MTX in Twin 1; an early discontinuation of MTX due to an adverse event in Twin 2). In both twins, the outcome of well-controlled anti-TNFα treatment (co-medication with MTX in Twin 1) for 10 years was expressed as low disease activity measured using composite index DAS28. It is interesting that Twin 2 had an unfavorable radiographic scoring after a 10-year follow-up than Twin 1 in spite of the comparable DAS28 in Twin 2 and smoking in Twin 1. In conclusion, co-medication of MTX with biologics may impact on RA radiographic progression despite predicted bad MTX outcome based on pharmacogenetic analysis.
24386983 CD8-positive T-cell lymphoproliferative disorder associated with Epstein-Barr virus-infect 2016 We report a 48-year-old female who developed lymphoproliferative disorder (LPD) during treatment of rheumatoid arthritis (RA) with methotrexate (MTX). She presented with multiple tumors in the cervical lymph nodes (LNs), multiple lung shadows and round shadows in both kidneys with pancytopenia and a high CRP level. The LN showed CD8-positive T-cell LPD associated with Epstein-Barr (EB) virus-infected B-cells. Clonality assays for immunoglobulin (Ig) heavy chain and T-cell receptor gamma (TCRγ) were negative. The cessation of MTX without chemotherapy resulted in the complete disappearance of the tumors and abnormal clinical features. We compared this case with previously published ones and discuss the pathological findings, presuming that the proliferation of CD8 T-cells was a reactive manifestation to reactivated EB virus-infected B-cells.
27312168 Immunomodulation of rheumatologic disorders with non-biologic disease modifying antirheumt 2016 Apr Although biological agents have revolutionized the immunomodulation of many rheumatic disorders, conventional disease modifying antirheumatic drugs (DMARDs) remain important glucocorticosteroid sparing agents and combination partners. In rheumatoid arthritis, low-dose glucocorticosteroids can be regarded as a DMARD due to preventive effects on joint erosions. Therapy with methothrexate and possibly also other DMARDs may alter the natural evolution of rheumatoid arthritis severity over time and therapy should be instituted as early as possible. Leflunomide is an equipotent alternative to methotrexate in rheumatoid arthritis, if methotrexate cannot be tolerated. Hydroxychloroquine inhibits toll-like receptor signaling and exerts antithrombotic and antihyperlipidemic effects, all thought to be beneficial in systemic lupus erythematosus. Hydroxychloroquine improves organ involvement in lupus, prevents lupus flares, and reduces mortality. It should be given to every lupus patient without contraindications.
26457478 Progression of palindromic rheumatism to juvenile idiopathic arthritis in a Japanese girl 2018 Mar Palindromic rheumatism (PR), a rare disease in children, is characterized by recurrent arthritis or periarthritis and asymptomatic interval. We report evolution of PR to juvenile idiopathic arthritis in a Japanese girl with heterozygous complex L110P-E148Q allele of MEFV gene. Poor response to colchicine alone suggests that the MEFV substitution could increase the susceptibility to arthritis rather than caused arthritis associated with atypical Familial Mediterranean Fever. Weekly methotrexate is a choice for such cases.
26715450 MDR-1 and MRP-1 activity in peripheral blood leukocytes of rheumatoid arthritis patients. 2015 Dec 30 BACKGROUND: Rheumatoid Arthritis is a chronic disease leading to decreased quality of life with a rather variable response rate to Disease Modifying Anti Rheumatic Drugs. Methotrexate (MTX) is the gold standard therapy in Rheumatoid Arthritis. The Multidrug resistance Related Protein and Multi Drug Resistance protein 1, also called P-glycoprotein-170 transporters can alter the intracellular concentration of different drugs. Methotrexate is an MRP1 substrate and thus the functional activity of MRP1 might have a clinical impact on the efficiency of the Methotrexate-therapy in Rheumatoid Arthritis. METHODS: We have compared the functional Multidrug Activity Factors (MAF) of the MDR1 and MRP1 transporters of Peripheral Blood Leukocytes of 59 Rheumatoid Arthritis patients with various response rate to MTX-therapy (MTX-responder, MTX-resistant and MTX-intolerant RA-groups) and 47 non-RA controls in six different leukocyte subpopulations (neutrophil leukocytes, monocytes, lymphocytes, CD4+, CD8+ and CD19+ cells). There was a decreased MAF of RA patients compared to non- Rheumatoid Arthritis patients and healthy controls in the leukocyte subpopulations. There was a significant difference between the MAF values of the MTX-responder and MTX intolerant groups. But we have not found significant differences between the MAF values of the MTX-responder and MTX-resistant Rheumatoid Arthritis -groups. RESULTS: Our results suggest that MDR1 and MRP1 functional activity does not seem to affect the response rate to MTX-therapy of Rheumatoid Arthritis-patients, but it might be useful in predicting MTX-side effects. We have demonstrated the decreased functional MDR-activity on almost 60 Rheumatoid Arthritis patients, which can be interpreted as a sign of the immune-suppressive effect of the MTX-treatment.
27149868 Update on Therapeutic Approaches for Rheumatoid Arthritis. 2016 Rheumatoid arthritis is a common chronic inflammatory and destructive arthropathy that consumes considerable personal, social and economic costs. It consists of a syndrome of pain, stiffness and symmetrical inflammation of the synovial membrane (synovitis) of freely moveable joints such as the knee (diarthrodial joints). Although the etiology of rheumatoid arthritis is unclear, the disease is characterized by inflammation of the synovial lining of diarthrodial joints, high synovial proliferation and an influx of inflammatory cells, macrophages and lymphocytes through angiogenic blood vessels. Diseasemodifying antirheumatic drugs slow disease progression and can induce disease remission in some patients. Methotrexate is the first line therapy, but if patients become intolerant to this drug, biologic agents should be used. The development of biological substances for the treatment of rheumatic conditions has been accompanied by ongoing health economic discussions regarding the implementation of these highly effective, but accordingly, highly priced drugs are the standard treatment guidelines of rheumatic diseases. In this way, more efficient strategies have to be identified. Despite numerous reviews in rheumatoid arthritis in the last years, this area is in constant development and updates are an urgent need to incorporate new advances in rheumatoid arthritis research. This review highlights the immunopathogenesis rationale for the current therapeutic strategies in rheumatoid arthritis.
26841182 [Methotrexate - anchor drug in the treament of rheumatoid arthritis]. 2016 Feb Methotrexate is in the centre of the treatment of rheumatoid arthritis. There are new insights in the understanding of its mechanism: intracellular polyglutamation activates the methotrexate molecule. The magnitude of this step is associated with response to the treatment. Further on, it was found that even low doses of methotrexate are sufficient to guarantee its effect as comedication of TNF-inhibitors. Finally, from the follow-up of long term cohorts it seems that methotrexate reduces mortality in rheumatoid arthritis independently from its effect on disease activity.
26847108 A prospective, single-centre, randomised study evaluating the clinical, imaging and immuno 2016 Feb 5 BACKGROUND: Rheumatoid arthritis (RA) is a chronic inflammatory arthritis, with significant impact on quality of life and functional status. Whilst biologic disease modifying anti-rheumatic drugs (bDMARD) such as tumour necrosis factor-inhibitor (TNFi) agents have revolutionised outcomes in RA, early diagnosis with immediate conventional therapy, titrated in a treat to target approach is also associated with high remission rates. The main aim of the VEDERA study (Very Early versus Delayed Etanercept in Rheumatoid Arthritis) is to assess the depth of remission, sustainability of remission and immunological normalisation induced by very early TNFi with etanercept (ETN) or standard of care +/- delayed ETN. METHODS/DESIGN: VEDERA is a pragmatic, phase IV single-centre open-label randomised superiority trial of 120 patients with early, treatment-naive RA. Patients will be randomised 1:1 to first-line ETN and methotrexate (MTX) or MTX with additional synthetic disease modifying anti-rheumatic drugs (sDMARDs) according to a treat to target (TT) protocol with further step up to ETN and MTX after 24 weeks if remission is not achieved. Participants will have regular disease activity assessments and imaging evaluation including musculoskeletal ultrasound and MRI. The main objective of this study is to assess the proportion of patients with early RA that achieve clinical remission at 48 weeks, following either treatment strategy. In addition, the participants are invited to take part in a cardio-vascular sub-study (Coronary Artery Disease in RA, CADERA), which aims to identify the incidence of cardiovascular abnormalities in early RA. DISCUSSION: The hypothesis underlining this study is that very early treatment with first-line ETN increases the proportion of patients with rheumatoid arthritis achieving clinical remission, in comparison to conventional therapy. TRIAL REGISTRATION: NCT02433184 , 23/04/2015.
27631530 [Management of rheumatoid arthritis]. 2016 Nov Rheumatoid arthritis is the most common inflammatory rheumatic disease. Due to the destruction of joints in the course of the disease it leads to significant morbidity in affected patients. The quality of life and even life expectancy can be severely impaired. Early diagnosis and early initiation of treatment is a decisive step towards a more benign course of the disease. New classification criteria have been published in order to help in early diagnosis. Methods of imaging, such as ultrasound and magnetic resonance imaging help in the detection of synovitis, which is the major pathomorphological manifestation of arthritis and should be identified without any doubt. Treatment follows the rule of treat to target with the aim of achieving remission or if this is not realistic, at least the lowest possible level of disease activity. The first and perhaps most important step in therapy is the initiation of methotrexate or if contraindications are present, another disease-modifying antirheumatic drug (DMARD) as soon as the diagnosis is made. Initial addition of glucocorticoids is recommended, which should be reduced in dose and terminated as soon as possible. Furthermore, either the combination of different DMARDs or the start of biologic DMARDs, such as tumor necrosis factor alpha (TNF-alpha) inhibitors or second generation biologic DMARDs is possible as a treatment option. The treatment follows the rule of shared decision-making and is the standard to treat comorbidities, the use an interdisciplinary approach and to treat functional deficits by rehabilitation measures, such as physiotherapy.
26932398 Current concepts in the management of rheumatoid arthritis. 2016 Mar Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by inflammation and joint destruction that causes significant morbidity and mortality. However, the combined use of methotrexate, a synthetic disease-modifying antirheumatic drug (DMARD), and biologic DMARD has revolutionized treatment of RA. Clinical remission is now realistic targets, achieved by a large proportion of RA patients, and rapid and appropriate induction of remission by intensive treatment with biological DMARD and methotrexate is prerequisite to halt joint damage and functional disabilities. However, biological DMARD is limited to intravenous or subcutaneous uses and orally available small but strong molecules have been developed. Oral administration of tofacitinib targeting the Janus kinase (JAK) is significantly effective than placebo in active patients with methotrexatenaïve, inadequately responsive to methotrexate or tumor necrosis factor (TNF)-inhibitors. The efficacy was rapid and as strong as adalimumab, a TNF-inhibitor. Meanwhile, association of tofacitinib on carcinogenicity and malignancy is under debate and further investigation on post-marketing survey would be warranted. On the other hand, discontinuation of a biological DMARD without disease flare is our next goal and desirable from the standpoint of risk reduction and cost effectiveness, especially for patients with clinical remission. Recent reports indicate that more than half of early RA patients could discontinue TNF-targeted biological DMARD without clinical flare and functional impairment after obtaining clinical remission. Contrarily, for established RA, fewer patients sustained remission after the discontinuation of biological DMARD and "deep remission" at the discontinuation was a key factor to keep the treatment holiday of biological DMARD.
25757837 [Rheumatoid neutrophilic dermatitis]. 2015 Apr The rheumatoid neutrophilic dermatitis (RND) is a rare disease associated with severe cases of seropositive rheumatoid arthritis (RA) seen in middle-aged individuals. Mostly this disease presents with erythematous papules, plaques and nodules. In general, RND responds either to corticosteroids or systemic treatment of the RA. We present the case of a 70-year-old man with RND and severe RA that responded to systemic corticosteroids and methotrexate.
26247590 Subclinical Atherosclerosis in Patients with Rheumatoid Arthritis and Low Cardiovascular R 2015 BACKGROUND: To evaluate association between von Willebrand factor (vWF) activity, inflammation markers, disease activity, and subclinical atherosclerosis in patients with rheumatoid arthritis (RA) and low cardiovascular risk. METHODS: Above mentioned parameters were determined in blood samples of 74 non-diabetic, normotensive, female subjects, with no dyslipidemia(42 patients, 32 matched healthy controls, age 45.3±10.0 vs. 45.2±9.8 years). Intima-media thickness (IMT) was measured bilaterally, at common carotid, bifurcation, and internal carotid arteries. Subclinical atherosclerosis was defined as IMT>IMTmean+2SD in controlsat each carotid level and atherosclerotic plaque as IMT>1.5 mm. Majority of RA patients were on methotrexate (83.3%), none on steroids >10 mg/day or biologic drugs. All findings were analysed in the entire study population and in RA group separately. RESULTS: RA patients with subclinical atherosclerosis had higher vWF activity than those without (133.5±69.3% vs. 95.3±36.8%, p<0.05). Predictive value of vWF activity for subclinical atherosclerosis was confirmed by logistic regression. vWF activity correlated significantly with erythrocyte sedimentation rate, fibrinogen, modified disease activity scores (mDAS28-ESR, mDAS28-CRP), modified Health Assessment Questionnaire (p<0.01 for all), duration of smoking, number of cigarettes/day, rheumatoid factor concentration (p<0.05 for all), and anti-CCP antibodies (p<0.01). In the entire study population, vWF activity was higher in participants with subclinical atherosclerosis (130±68% vs. 97±38%, p<0.05) or atherosclerotic plaques (123±57% vs. 99±45%, p<0.05) than in those without. Duration of smoking was significantly associated with vWF activity (β 0.026, p = 0.039). CONCLUSIONS: We demonstrated association of vWF activity and subclinical atherosclerosis in low-risk RA patients as well as its correlation with inflammation markers, all parameters of disease activity, and seropositivity. Therefore, vWF might be a valuable marker of early atherosclerosis in RA patients.
24285493 Time trends in disease activity, response and remission rates in rheumatoid arthritis duri 2015 Feb OBJECTIVES: To investigate whether baseline disease activity levels and responses in patients with rheumatoid arthritis (RA) changed during the period 2000-2010. METHODS: Data were provided by the Norwegian disease-modifying antirheumatic drug (NOR-DMARD) study. Patients with inflammatory joint diseases starting new treatment with disease-modifying antirheumatic drugs (DMARDs) were consecutively included and followed longitudinally. Time trend analyses were performed in methotrexate (MTX)-naïve RA patients starting MTX monotherapy (MTX mono) and biologic DMARD (bDMARD)-naïve RA patients starting tumour necrosis factor inhibitors+MTX (TNFi+MTX). RESULTS: A total of 2573 patients were included in the analyses: MTX mono n=1866 (69.9% female, 62.0% RF+, mean (SD) age 56.0 (13.7) years, median (25-75 percentile) time from diagnosis 0.2 (0.01-2.8) years); TNFi+MTX n=707 (70.3% female, 75.0% RF+, mean (SD) age 52.1 (13.2) years, median (25-75 percentile) time from diagnosis 5.7 (2.0-13.7) years). Significant time trends towards lower baseline disease activity score 28 (DAS28) as well as other disease activity measures were found in both groups (DAS28 from 5.17 to 4.75 in MTX mono and from 5.88 to 4.64 in TNFi+MTX), and disease duration became shorter. Six-month DAS28 remission rates increased significantly over the years (from 17.8 to 37.6 in MTX mono and from 16.9 to 46.3 in TNFi+MTX). CONCLUSIONS: During the last decade, baseline RA disease activity level at the time of starting MTX as well as TNFi+MTX decreased from high to moderate. A more than twofold increase in 6-month remission rates was observed in both groups. Our findings indicate that clinicians have implemented modern, more aggressive treatment strategies, which hopefully will lead to better long-term disease outcomes.
26995880 [Optimal Treatment for Rheumatoid Arthritis with Companion Diagnostics]. 2015 Nov The medical strategy for rheumatoid arthritis (RA) has markedly advanced in recent years. The introduction of biologics in addition to methotrexate, an anchor drug, has made it possible to not only suppress pain and inflammation (clinical remission), but also inhibit joint destruction (structural remission), leading to cure from the disease. Since the condition and pathology are heterogeneous among individual patients, optimal treatment for each patient based on the use of companion diagnostics is desired (precision medicine). ACPA is important to diagnose RA, but also to assess the prognosis. ACPA is also a part of companion diagnostics for preclinical RA because it has been found to be positive before the onset. Treatment should be performed under consideration of the disease state such as activity, prognosis regarding joint destruction, and complications. It is also important to clarify the patient characteristics, such as responsiveness to the drugs and risk of adverse effects. Biomarkers, such as proteomics and pharmacogenomics, have been reported as companion diagnostics for optimal treatment of RA. RA is a multifactorial disorder with clinically heterogeneous features. Gene-environment interaction is closely involved in the production of ACPA, and then secondary stimuli to joints may lead to symptoms of RA. Joint injury, emotional stress, and infections often trigger the onset of RA. It is possible to cure RA, achieving complete remission, by early aggressive treatment and returning to the pre-clinical state with environmental improvement. [Review]
25487291 Trend of patient characteristics and its impact on the response to adalimumab in patients 2015 Jul OBJECTIVES: To investigate the relationship between changes in patient characteristics over time and the effectiveness and safety of adalimumab in the treatment of rheumatoid arthritis (RA) in clinical practice. METHODS: Patients enrolled in the post-marketing registry study in Japan were divided into 5 subgroups based on the time adalimumab treatment was initiated. Demographic and baseline characteristics and responses to adalimumab were compared among the 5 subgroups to detect any time-course trend. Multiple logistic regression analysis was performed to identify characteristics that were significantly associated with the effectiveness or safety of adalimumab and to estimate response rates and the incidence of adverse drug reactions in individual subgroups. RESULTS: During the study period, patient characteristics changed significantly over time, in particular with regard to prior biologic use and concomitant methotrexate therapy. There was a significant trend toward higher response rates and lower incidence of infections and injection-site reactions in patients initiating adalimumab later in the study. Patient characteristics, such as concomitant methotrexate therapy and early stage RA, were significant predictors of the effectiveness and safety of adalimumab. CONCLUSIONS: Patient characteristics have changed since adalimumab became available for the treatment of RA; several of these characteristics were significant predictors of adalimumab effectiveness and safety.
27126059 Effect of early treatment on physical function in daily management of rheumatoid arthritis 2018 Apr AIM: The purpose of this study was to assess 5-year changes in physical function and factors associated with improvement among patients with rheumatoid arthritis (RA) in daily clinical practice, focusing on the effect of treatments, including biologic agents, in the early stage of disease course. METHODS: The National Database of Rheumatic Diseases by iR-net in Japan (NinJa) was searched for patients with disease duration ≤ 2 years and modified health assessment questionnaire (mHAQ) > 0 between 2004 and 2007, so that 510 patients were included in the final analysis. Multivariate-logistic regression analyses were used to identify predictors of 5-year mHAQ disability score improvement. RESULTS: Median mHAQ score was 0.40 at baseline and decreased to a median 0.17 after 5 years. Seventy-four percent of the patients were treated with methotrexate (MTX) and 25% with biologic agents, with early use of biologic agents (within 2 years of RA onset) increasing over time. Multivariate analyses identified higher baseline Disease Activity Score of 28 joints - C-reactive protein and early use of MTX (within 1 year of RA onset) and of biologic agents (within 2 years) as significantly associated with improved mHAQ; odds ratios of the early treatment were 1.83 (P = 0.01) for MTX and 2.23 (P = 0.04) for biologic agents, respectively. CONCLUSION: Five-year mHAQ improved in early RA patients in the NinJa database. In daily clinical management of RA, likewise in clinical trials, early administration of MTX or biologic agents is able to improve physical function outcome.
26833350 Targeting Low Disease Activity in Elderly-Onset Rheumatoid Arthritis: Current and Future R 2016 Feb Elderly rheumatoid arthritis (RA) is classified into two clinical subsets, elderly-onset RA (EORA) and younger-onset elderly RA. With the improvement of life expectancy in the general population and advent of the super-aging society, the number of patients with EORA is anticipated to increase. Both large and small joints are affected initially at onset, and individuals with early EORA have higher scores of disease activity and levels of acute-phase reactants than those with early younger-onset RA. EORA is a progressive disease similar to younger-onset RA. Tumor necrosis factor (TNF) inhibitors are equally or slightly less effective in elderly patients than in younger patients with RA, and disease duration may have a greater impact on disease outcomes than age. Evidence of non-TNF biological disease-modifying antirheumatic drug use in EORA is limited. TNF inhibitors may not increase the risk for infection in elderly patients any more than methotrexate; however, increasing age is an independent and strong risk factor for serious infections in patients with RA. Treatment choice in patients with EORA is strongly influenced by comorbidities, especially cardiovascular disease, chronic lung disease, and frailty. To prevent progression to irreversible geriatric syndromes, non-frail patients with EORA, who are aging successfully should undergo intensive treatment using the treat-to-target strategy, and pre-frail and frail patients with EORA should be treated with the aim of returning to a non-frail or pre-frail stage, respectively. An appropriate treatment strategy for EORA and younger-onset elderly RA should be developed in the next decade using a multi-disciplinary approach.
27432355 Relationship of patient-reported outcomes with MRI measures in rheumatoid arthritis. 2017 Mar PURPOSE: We assessed whether MRI measures of synovitis, osteitis and bone erosion were associated with patient-reported outcomes (PROs) in a longitudinal clinical trial setting among patients with rheumatoid arthritis (RA). METHODS: This longitudinal cohort of 291 patients with RA was derived from the MRI substudy of the GO-BEFORE randomised controlled trial of golimumab among methotrexate-naïve patients. Correlations between RAMRIS scores (synovitis, osteitis, bone erosion) and physical function (Health Assessment Questionnaire (HAQ)), pain and global patient scores were determined at 0, 12, 24 and 52 weeks. Correlations between interval changes were also assessed. Multivariable regression models using robust generalised estimating equations evaluated associations over all time-points and their relationship to other clinical disease activity measures. RESULTS: Greater synovitis, osteitis and bone erosion scores were positively associated with HAQ at all time-points (all p<0.05) and with pain and patient global scores at 24 and 52 weeks. Over all visits, synovitis was associated with HAQ, pain and patient global scores (p≤0.03) independent of clinical disease activity measures. Improvements in synovitis and bone erosion were also associated with improvements in PROs. Less improvement in synovitis and progression in MRI erosion at 52 weeks were both independently associated with worsening in all PROs at 52 weeks while progression on X-ray was not associated. Similar associations were observed across treatment groups. CONCLUSIONS: MRI measures of inflammation and structural damage correlate independently with physical function, pain and patient global assessments. These observations support the validity of MRI biomarkers. TRIAL REGISTRATION NUMBER: NCT00264537; Post-results.
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.
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.
