29950288 | An Online Hand Exercise Intervention for Adults With Rheumatoid Arthritis (mySARAH): Desig | 2018 Jun 27 | BACKGROUND: The Strengthening and Stretching for Rheumatoid Arthritis of the Hand (SARAH) program is a tailored, progressive 12-week exercise program for people with hand problems due to rheumatoid arthritis. The program was shown to be clinically and cost-effective in a large clinical trial and is recommended by the UK National Institute for Health and Care Excellence (NICE) guidelines for rheumatoid arthritis in adults. OBJECTIVE: We have developed an online version of the SARAH program (mySARAH) to make the SARAH program widely accessible to people with rheumatoid arthritis. The purposes of this study were to develop mySARAH and to evaluate and address its usability issues. METHODS: We developed mySARAH using a three-step process and gaining feedback from patient contributors. After initial development, mySARAH was tested in two iterative usability cycles in nine participants using a simplified think-aloud protocol and self-reported questionnaires. We also evaluated if participants executed the SARAH exercises correctly after watching the exercise videos included on the website. RESULTS: A preliminary version of mySARAH consisting of six sessions over a 12-week period and delivered via text, exercise videos, images, exercise plan form, exercise calendar, and links to additional information on rheumatoid arthritis was developed. Five participants (1 male; 4 females; median age 64 years) and four participants (four females; median age 64.5 years) took part in the first and second usability testing cycles respectively. Usability issues identified from Cycle 1 such as having a navigation tutorial video and individualised feedback on pain levels were addressed prior to Cycle 2. The need for more instructions to complete the mySARAH patient forms was identified in Cycle 2 and was rectified. Self-reports from both cycles indicated that participants found the program useful and easy to use and were confident in performing the SARAH exercises themselves. Eight of the nine participants correctly demonstrated all the exercises. CONCLUSIONS: mySARAH is the first online hand exercise intervention for people with rheumatoid arthritis. We actively involved target users in the development and usability evaluation and ensured mySARAH met their needs and preferences. | |
29600939 | Chinese registry of rheumatoid arthritis (CREDIT): I. Introduction and prevalence of remis | 2018 Sep | OBJECTIVES: To introduce the Chinese Registry of rhEumatoiD arthrITis (CREDIT), which is the first nationwide, multicentre, online rheumatoid arthritis (RA) registry in China, and to depict major cross-sectional data and treatment strategies of Chinese RA patients. METHODS: RA patients who fulfilled the 2010 ACR/EULAR classification criteria for rheumatoid arthritis were recruited into the registry by their rheumatologists from 144 clinical centres in China. Data, including demographics, disease characteristics, co-morbidities, treatment, and adverse reactions, were collected and documented through the predefined protocol. RESULTS: 8071 registered patients (F:M = 4.03:1) were registered up to May 2017. Mean age at symptom onset and at diagnosis was 46.15±14.72y and 48.68±14.54y, respectively. Point prevalence of remission (95% CIs) was 14.88% (14.10-15.66%), 4.23% (3.79-4.66%), 4.25% (3.81-4.69%), and 4.27% (3.83-4.72%) according to DAS28-CRP, CDAI, SDAI, and the 2011 ACR/EULAR remission criteria, respectively. 38.84% and 38.11% of treatment-naïve patients (n=3262) were in moderate (3.2 |

30241878 | Health care utilization and expenditures among adults with rheumatoid arthritis using spec | 2019 Jun | BACKGROUND: Despite the rising popularity of using specialty medications for patients with rheumatoid arthritis (RA), little is known about the use or spending on medical services among these patients. OBJECTIVE: The objective of this study was to investigate health care utilization and expenditures among patients with RA using specialty medications compared with those using non-specialty (i.e., traditional) medications. METHODS: This was a retrospective cohort study using Medical Expenditure Panel Survey data from 2009 through 2015. Health care use and expenditures were examined using a (zero-truncated or zero-inflated) negative binomial model and a generalized linear model with a log link function and gamma distribution (or a two-part model). RESULTS: Compared to patients with RA who were traditional medication users (TMUs), those categorized as specialty medication users (SMUs) were prescribed about 24% fewer medications (incidence rate ratio [IRR] = 0.76, 95% CI = 0.66-0.89) and received fewer office-based visits (IRR = 0.84, 95% CI = 0.70-0.99). Although SMUs' spending on emergency department visits was lower, their spending on total health care was $14,570 higher than that of TMUs. Compared with TMUs, users of both specialty and traditional medications (BMUs) had fewer emergency department visits (IRR = 0.57, 95% CI = 0.39-0.81) with less spending on emergency service use. Overall, BMUs' total health care spending was $5720 higher than TMUs' total spending. CONCLUSIONS: There were some differences in health care use and expenditures for treating RA between patients using specialty medications and those using traditional medications. Total health care spending was higher for SMUs/BMUs despite their less frequent use of some types of medical services and lower spending on emergency department visits, because of the high cost of specialty medications for RA. The high costs of specialty medications implies the importance of the efficient use of these medications. | |
30047436 | Inflammatory arthritis and crystal arthropathy: Current concepts of skin and systemic mani | 2018 Jul | Systemic inflammatory disorders frequently involve the skin, and when cutaneous disease develops, such dermatologic manifestations may represent the initial sign of disease and may also provide valuable prognostic information about the underlying disorder. Familiarity with the various skin manifestations of systemic disease is therefore paramount and increases the likelihood of accurate diagnosis, which may facilitate the implementation of an appropriate treatment strategy. An improvement in quality of life and a reduction in the degree of morbidity may also be a realized benefit of accurate recognition of these skin signs. With this context in mind, this review highlights the salient clinical features and unique dermatologic manifestations of rheumatoid arthritis, adult-onset Still's disease, and the crystal arthropathy, gout. | |
30558013 | Recognition of gout in rheumatoid arthritis: A case report. | 2018 Dec | RATIONALE: Rheumatoid arthritis (RA) and gout are common rheumatic diseases. However, their coexistance has been rarely reported. Here in, we describe a case of a middle aged Chinese woman having RA complicated with atypical gout on both the knee joints. PATIENT CONCERNS: A 44-year-old Chinese woman complained of swelling and tenderness of multiple joints since 10 months. She had a positive rheumatoid factor and high titers of anti-CCP antibody. She was diagnosed with RA, and commenced on methotrexate, leflunomide, and methylprednisolone. Her symptoms of pain and swelling over interphalangeal and wrists joints subsided except the knee joints. She was started with treat to target treatment (TTT) for RA and rest of her medications was adjusted accordingly. Surprisingly, her symptoms did not improve ever after the addition of a biologic agent, tumor necrosis factor (TNF)-α receptor antagonist. DIAGNOSIS: Presence of urate crystals in the synovium was viewed under polarization microscope which was extracted from one of the knee joint. Hence, we established the diagnosis of RA complicated with gout. INTERVENTIONS: We commenced her on TNF-α receptor antagonist, colchicines, and febuxostat. OUTCOMES: Her symptoms of pain and swelling improved significantly on both the knees and no longer recurred. LESSONS: Coexistence of RA and gout has been rarely reported as it is not frequently seen in clinical practice. Hence, when patients with RA with oligoarthritis repeatedly do not respond to TTT, a standard antirheumatism treatment, the possibility of RA complicating with gout should be rule out. | |
30271781 | Unmet Needs in the Treatment of RA in the Era of Jak-i: IDRA (Italian Delphi Rheumatoid Ar | 2018 | Rheumatoid arthritis is the most common autoimmune arthritis in adult population. This disease is characterized by joint damage and systemic involvement that lead to general physical and mental impairment with consequent worsening of quality of life. Rheumatoid arthritis is also associated with a large economic burden to healthcare systems. The evidence from the literature indicates that, despite available treatments, several unmet needs still interfere with rheumatoid arthritis management. Based on this evidence, some of the unmet medical needs currently present in the management of the rheumatoid arthritis were identified and a Delphi questionnaire was submitted to 60 Italian Rheumatologists. The aim of this Delphi was to achieve a broad consensus on the most relevant unmet needs identified, in order to present the Italian reality in view of the availability of new molecules that could provide an effective therapeutic option in the treatment of patients with rheumatoid arthritis. | |
30586666 | Study of the adoptive immunotherapy on rheumatoid arthritis with Thymus-derived invariant | 2019 Feb | BACKGROUND: The therapeutic effect of adoptive infusion of specific thymus-derived invariant natural killer T (iNKT) cells in a mouse model of rheumatoid arthritis (RA) was observed, and the mechanism of cellular immunotherapy was preliminarily explored. METHODS: Thymus-derived iNKT cells were infused to RA model mice, with α-GalCer as a positive control. Then, ankle swelling was examined, as well as inflammatory cell infiltration to the joint tissue (hematoxylin-eosin [H&E] staining). Flow cytometry (FCM) was used to assess iNKT cell and helper T lymphocyte (Th) subsets. Serum cytokine levels were determined with cytometric bead array (CBA), with protein expression levels of related transcription factors assessed by Western blot. RESULTS: The joint swelling in RA model animals were significantly improved in the cell therapy and α-GalCer positive control groups (P < 0.05). In addition, iNKT frequencies in peripheral blood, the thymus and spleen were increased significantly (P < 0.05). Meanwhile, iNKT1 subset frequencies in the thymus and spleen were decreased, as well as splenic Th1 and Th17 cell subset rates, and serum TNF-α, IFN-γ and IL-6 levels. The rates of iNKT2 and Th2 subsets as well as IL-4 and IL-10 levels were increased (P < 0.05). Thymus GATA-3 and splenic PLZF protein levels were increased (P < 0.05). CONCLUSIONS: Adoptive infusion of thymus-derived iNKT cells exerts therapeutic effects in RA mice by increasing iNKT frequency, altering the proportions of iNKT cell subsets, correcting Th cell subset imbalance and reducing the amounts of inflammatory cytokines. | |
29614581 | [2018 Chinese guideline for the diagnosis and treatment of rheumatoid arthritis]. | 2018 Apr 1 | To develop a new evidence-based diagnosis, treatment guideline for rheumatoid arthritis (RA) in China.A multidisciplinary guideline development group was established. The grading of recommendations assessment, development and evaluation (GRADE) system was used to rate the quality of evidence and the strength of recommendations. Recommendations were derived from evidence body, the balance of benefits and harmsand patient's values and preferences.The guideline development group developed 10 recommendations for the diagnosis and treatment of RA. The guideline covered the classification criteria, disease activity monitoring and assessing, antirheumatic drugs (DMARDs) and glucocorticoids with treat-to-target approach of RA.This rheumatoid arthritis guideline was intended to serve as a tool for clinicians and patients for best decisions-making in China. | |
30100905 | Glycogen Metabolism and Rheumatoid Arthritis: The Role of Glycogen Synthase 1 in Regulatio | 2018 | OBJECTIVE: To investigate the role of glycogen metabolism in regulating rheumatoid fibroblast-like synoviocyte (FLS)-mediated synovial inflammation and its underlying mechanism. METHODS: FLSs were separated from synovial tissues (STs) obtained from rheumatoid arthritis (RA) patients. Glycogen content was determined by periodic acid Schiff staining. Protein expression was analyzed by Western blot or immunohistochemistry. Gene expression of cytokines and matrix metalloproteinases (MMPs) was evaluated by quantitative real-time PCR. FLS proliferation was detected by EdU incorporation. Migration and invasion were measured by Boyden chamber assay. RESULTS: Glycogen levels and glycogen synthase 1 (GYS1) expression were significantly increased in the ST and FLSs of RA patients. TNF-α or hypoxia induced GYS1 expression and glycogen synthesis in RA FLSs. GYS1 knockdown by shRNA decreased the expression of IL-1β, IL-6, CCL-2, MMP-1, and MMP-9 and proliferation and migration by increasing AMP-activated protein kinase (AMPK) activity in RA FLS. AMPK inhibitor or knockdown AMPK could reverse the inhibitory effect of GYS1 knockdown on the inflammatory response in RA FLSs; however, an AMPK agonist blocked RA FLS activity. We further determined that hypoxia-inducible factor-1α mediates TNF-α- or hypoxia-induced GYS1 expression and glycogen levels. Local joint depletion of GYS1 or intraperitoneal administration with an AMPK agonist ameliorated the severity of arthritis in rats with collagen-induced arthritis. CONCLUSION: Our data demonstrate that GYS1-mediated glycogen accumulation contributes to FLS-mediated synovial inflammation in RA by blocking AMPK activation. In our knowledge, this is a first study linking glycogen metabolism to chronic inflammation. Inhibition of GYS1 might be a novel therapeutic strategy for chronic inflammatory arthritis, including RA. | |
28211251 | Burden of rheumatoid arthritis from a societal perspective: A prevalence-based study on co | 2018 Aug | AIM: To provide a comprehensive estimation of the economic burden of rheumatoid arthritis (RA) in China, especially for patients from less developed areas, and to explore the cost transferability between regions to assist healthcare decision-making. METHODS: The study was conducted in south and north China from May 2013 to December 2013. The burden of RA was investigated by interviewing participants with a questionnaire battery containing socio-demographic, cost of illness (COI) and medical treatments. The COI questionnaire captured direct, indirect and intangible costs. Direct costs included hospitalizations, outpatient visits and medications. Indirect costs were estimated using the human capital approach, and intangible costs valued through the willingness-to-pay approach. All cost data were converted to 2013 US dollars by purchasing power parity, and then summarized descriptively and analyzed with mixed models. RESULTS: Questionnaires were administered to 133 RA patients. The average direct costs were $1917.21 ± $2559.06 per patient year, with medications at $1283.89 ± $1898.15 comprising more than 50% of the total. The average indirect costs were $492.88 ± $1739.74 per patient year, while intangible costs were $20396.30 ± $31145.10. There was no significant difference detected between regions. Recent hospitalization was tested as a significant predictor of the direct costs. Age and income were significantly associated with indirect and intangible costs. CONCLUSIONS: Besides the substantial burden in terms of direct medical costs and productivity lost, there were notable intangible costs, especially among older patients. This conclusion could be potentially expanded to other provinces in China or even other countries through the adjustments for transferability. | |
29928272 | Comparison of Serological Biomarkers in Rheumatoid Arthritis and Their Combination to Impr | 2018 | INTRODUCTION: The diagnosis of rheumatoid arthritis (RA) is based on a combined approach that includes serological markers such as rheumatoid factor (RF) and anti-citrullinated peptide/protein antibodies (ACPA). The goal of this study was to evaluate the clinical performance of several RF and ACPA immunoassays for the diagnosis of RA, as well as the diagnostic value of a combinatory approach with these markers. METHODS: The study cohort included 1,655 patients from the Swiss Clinical Quality Management registry with sera from 968 patients with RA and 687 disease controls, including patients with axial spondyloarthritis (n = 450) and psoriatic arthritis (n = 237). ACPA were determined by anti-CCP2 IgG enzyme-linked immunosorbent assay (ELISA), QUANTA Flash(®) CCP3 IgG [chemiluminescent immunoassay (CIA)], and QUANTA Lite(®) CCP3 IgG ELISA. RF was determined by ELISA (QUANTA Lite(®) RF IgM, RF IgA, and RF IgG) and with two research use only CIAs (QUANTA Flash(®) RF IgM and RF IgA). RESULTS: All three ACPA assays showed good discrimination between RA patients and controls and good clinical performance. Overall, CCP3 performed better than CCP2. More pronounced differences were observed between the RF assays. We observed that CIA platforms for both RF IgM and RF IgA showed better performance than the ELISA platforms. Excellent and good total agreements were found between ELISA and CIA for CCP3 (total agreement 95.3%, kappa = 0.90), and between CCP2 and CCP3 ELISA (total agreement 86.6%, kappa = 0.73), respectively. RF IgM CIA and ELISA had a good qualitative agreement (86.5%, kappa = 0.73); RF IgA CIA and ELISA showed a moderate total agreement (78.5%, kappa = 0.53). When combinatory analyses were performed, the likelihood of RA increased with dual positivity and triple positivity and combining different markers resulted in higher odds ratio than the individual markers in all cases. CONCLUSION: ACPA and RF showed good clinical performance in this large Swiss cohort of RA patients and controls. Overall, the performance of CCP3 was superior to CCP2. The combination of these biomarkers in an interval model represents a potential tool for the diagnosis of RA patients. | |
30020745 | Cost of biologic treatment persistence or switching in rheumatoid arthritis. | 2018 Jul | OBJECTIVES: To estimate total costs among patients with rheumatoid arthritis (RA) who persisted on or switched from newly initiated biologic therapy. STUDY DESIGN: A retrospective claims database analysis. METHODS: This analysis included adults in the HealthCore Integrated Research Database with RA who initiated treatment with a biologic for RA (abatacept, adalimumab, certolizumab pegol, etanercept, golimumab, infliximab, rituximab, or tocilizumab) between January 2009 and November 2014. Total healthcare costs (plan- and patient-paid) were estimated for 1 year post index. Treatment persistence was defined as no discontinuation (ie, no refill gap >45 days) and no biologic switch. RESULTS: Of 7468 patients, 45.2% persisted on the index biologic for at least 1 year without a refill gap and 16.7% switched to another biologic in the first year; other patients discontinued the index biologic (23.2%) or restarted after a refill gap (15.0%). Mean 1-year total healthcare costs per patient were $41,901 (95% CI, $40,855-$42,947) among persistent patients and $44,244 (95% CI, $40,820-$47,668) among switchers. In a multivariable analysis of all patients, switchers had 5% higher postindex costs on average than persistent patients (exp(β) = 1.05; 95% CI, 1.01-1.08), and etanercept had the lowest postindex costs (exp(β) ranged from 1.03 to 1.51 for other biologics relative to etanercept). CONCLUSIONS: Patients with RA who switched biologic therapy incurred higher 1-year total postswitch healthcare costs compared with patients who were persistent on the index biologic. Healthcare costs were lowest for patients who started on etanercept, particularly those who persisted on etanercept. | |
28282737 | Choroidal Thickness Changes in Rheumatoid Arthritis and the Effects of Short-term Hydroxyc | 2018 | PURPOSE: The objective of this study is to evaluate choroidal thickness (CT) in patients with rheumatoid artritis (RA) and the effects of short-term hydroxychloroquine (HCQ) treatment. METHODS: Thirty RA patients (group 1) and 30 normal subjects (group 2) were enrolled in the study. Group 1 was further divided into two subgroups as follows: group 1A (Before HCQ treatment) and group 1B (1 year after HCQ treatment). The CTs were measured using optical coherence tomography (EDI-OCT). RESULTS: The mean subfoveal choroidal thickness (SFCT) (µm) was 335.70 ± 64.58 in group 1A, 341.85 ± 63.95 in group 1B, and 358.51 ± 63.83 in group 2. SFCT was significantly lower in groups 1A and 1B than in group 2 (p = 0.020 and p = 0.028, respectively). Group 1B presented statistically significant thicker SFCT than group 1A (p = 0.033). CONCLUSIONS: CT was significantly lower in RA patients than in normal subjects. HCQ treatment may, however, cause a statistically significant increase in SFCT. This increase is clinically negligible. | |
30124222 | Association of Periodontitis with Rheumatoid Arthritis and the Effect of Non-Surgical Peri | 2018 Aug 20 | BACKGROUND The association of periodontitis (PD) with the prevalence of rheumatoid arthritis (RA) remains controversial. Therefore, the aim of this study was to evaluate their correlation and investigate the effects of non-surgical periodontal treatment on RA. MATERIAL AND METHODS A total of 64 patients were enrolled in this study and divided into 4 groups: 18 PD patients (PD+RA-), 18 RA patients (PD-RA+), 18 RA with PD patients (PD+RA+), and 10 healthy controls (PD-RA-). Periodontal and rheumatologic parameters were examined at baseline and 1 month following non-surgical periodontal treatment. RESULTS Our results showed that RA patients had similar periodontal status. However, patients in the PD+RA+ group had significantly higher levels of rheumatologic parameters such as C-reactive protein (CRP), anti-cyclic citrulline peptide antibody (ACPA), erythrocyte sedimentation rate (ESR), and Disease Activity Score 28 (DAS28) than those in the PD-RA+ group. In addition, non-surgical periodontal treatment was efficacious in improving rheumatologic parameters of patients in the PD+RA+ group. CONCLUSIONS The presence of PD might contribute to the progression of RA, while RA might have little effect on accelerating the development of PD. In addition, RA patients with PD receiving non-surgical periodontal treatment resulted in noteworthy improvement in the clinical outcome for RA. | |
29287304 | The Tumor-Like Phenotype of Rheumatoid Synovium: Molecular Profiling and Prospects for Pre | 2018 May | Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by destructive hyperplasia of the synovium. Fibroblast-like synoviocytes (FLS) are a major component of synovial pannus and actively participate in the pathologic progression of RA. How rheumatoid FLS acquire and sustain such a uniquely aggressive phenotype remains poorly understood. We describe the current state of knowledge of the molecular alterations in rheumatoid FLS at the genomic, epigenomic, transcriptomic, proteomic, and metabolomic levels, which offers a means to reconstruct the pathways leading to rheumatoid pannus. Such data provide new pathologic insight and suggest means to more sensitively assess disease activity and response to therapy, as well as support new avenues for therapeutic development. | |
29731462 | [Diagnosis and treatment of rheumatoid arthritis:toward the best practice. Best practice o | 2018 | Complicated cytokine network is involved in the pathogenesis of rheumatoid arthritis(RA). Among various cytokines, interleukin(IL)-6 is particularly important. Efficacy and safety of IL-6 inhibitors have been proved for the past decade. Many researches have studied optimal usage of and predictive markers for IL-6 inhibitors. IL-6 inhibitors are expected to play a pivotal role in the management of RA in future. | |
29624625 | Clinical management of seronegative and seropositive rheumatoid arthritis: A comparative s | 2018 | Both rheumatoid factor (RF) and anti-cyclic citrullinated peptide antibody (ACPA) are associated with poor radiologic outcomes in patients with rheumatoid arthritis (RA). In general, RA patients positive for RF or ACPA (SPRA) are considered to manifest an aggressive disease course compared with seronegative RA patients (SNRA). However, the relationship between seropositivity and measures of disease severity other than radiologic outcome is disputed. In this study, we sought to compare the clinical presentations and treatment outcomes of SNRA and SPRA patients. A total of 241 patients diagnosed with DMARD-naïve RA under either 1987 American College of Rheumatology (ACR) criteria or 2010 ACR/European League Against Rheumatism (EULAR) criteria were identified (40 with SNRA and 201 with SPRA). We investigated the disease activity measures including ESR, CRP, patient VAS, 28 tender/swollen joint count (28 TJC, 28 SJC) and DAS28 as well as radiologic outcomes at baseline, 1 and 2 years after conventional treatment with DMARD. Age, sex and disease duration were similar between SNRA and SPRA. However, the baseline 28 TJC (4.7±2.9 vs. 3.3±2.7, p = 0.004), 28 SJC (4.3±3.0 vs. 2.9±2.3, p = 0.001) and DAS28 (5.1±1.0 vs. 4.7±1.0, p = 0.043) components were significantly higher in SNRA than in SPRA. Over 2 years of similar treatment with DMARDs, all disease activity measures significantly improved in both groups. Comparison among populations matched for baseline disease activity showed that ΔDAS28 at 1 year was greater in SNRA than in SPRA (-2.84±1.32 vs. -3.70±1.29, p = 0.037) in high disease activity population (DAS28-ESR>5.1). Radiologic outcomes at baseline and at 1- or 2-year follow-up were similar between the 2 groups. In conclusion, SNRA patients manifested more active disease at baseline, but showed a better response to treatment compared with SPRA. SNRA does not appear to be a benign subtype of RA. | |
30020744 | Two-year adherence and costs for biologic therapy for rheumatoid arthritis. | 2018 Jul | OBJECTIVES: To evaluate adherence to newly initiated biologic disease-modifying antirheumatic drugs (bDMARDs) in effectively treated patients with rheumatoid arthritis (RA). STUDY DESIGN: Retrospective cohort study of administrative claims data (IMS PharMetrics Plus) for services incurred from July 1, 2008, to December 31, 2014. METHODS: Data from patients with RA aged 18 to 64 years with continuous enrollment for at least 30 months and initiating abatacept, adalimumab, certolizumab pegol, etanercept, golimumab, or infliximab were analyzed. Treatment effectiveness was determined using a validated algorithm. Outcomes included adherence rates (proportion of days covered ≥80%) for 1 year and 2 years, year 2 adherence among patients effectively and noneffectively treated in year 1, year 2 adherence predictors, and year 2 costs and cost predictors. RESULTS: Across 10,374 patients, adherence rates were 46% for year 1 and 34% for 2 years; rates were lowest for golimumab and highest for infliximab. In year 1, 3076 (29.7%) patients were considered effectively treated. Year 2 adherence was 59% in effectively treated patients, 32% in patients who failed any effectiveness criteria, and 12% in patients who failed only the adherence criterion. Intravenous bDMARDs, older age, male sex, Northeast region, commercial payer, prior DMARD use, index year 2010 or later, and lower preindex all-cause costs each predicted better adherence. Adjusted year 2 all-cause and RA-related costs were $39,425 and $22,123, respectively, for effectively treated patients and $25,313 and $9250 for noneffectively treated patients. Cost predictors included effective treatment, region, payer, and index year. CONCLUSIONS: Adherence to the first bDMARD was suboptimal even in effectively treated patients, suggesting opportunities to improve adherence in patients with RA initiating biologics. | |
30497868 | FRAX 10-yr Fracture Risk in Rheumatoid Arthritis-Assessments With and Without Bone Mineral | 2019 Jan | OBJECTIVES: FRAX is a computer-based algorithm developed by the World Health Organisation for estimation of the 10-yr risk of a hip or major osteoporotic fracture. Inclusion of femoral neck bone mineral density (BMD) in the estimation is optional. The study aimed to investigate the intra-individual agreement between FRAX fracture risk calculated with and without BMD in patients with rheumatoid arthritis (RA). METHODS: Clinical data and BMD results from 50 RA patients registered in the Danish rheumatology registry (DANBIO) were used for analysis. Using the Bland-Altman method, lower and upper 95% limits of agreement [LLoA;ULoA] between intraindividual assessments of fracture risk with and without BMD and the bias (mean of individual differences) were calculated. Categorization of patients according to the National Osteoporosis foundation (NOF) treatment thresholds were also assessed with and without BMD. RESULTS: Mean age was 63.6 ± 11.7 yr, mean disease activity score (DAS28-CRP) 3.3 ± 3.5 and mean femoral neck T-score -1.43 ± 1.15. The mean 10-yr risk of a major fracture and a hip fracture calculated with BMD was 22.9 ± 15.8% and 8.5 ± 10.8%, respectively. The LLoA and ULoA [bias] calculated without vs with BMD were -14.5 and 20.4 percent point (pp) [2.9 pp] for major fracture risk and -14.0 and 23.2 pp [4.6 pp] for hip fracture. NOF treatment categorization was only dependent on BMD in 4% of the patients. CONCLUSION: The FRAX fracture risk estimated with and without BMD may disagree substantially in individual patients with RA but this seems to have only little impact on treatment categorization based on the NOF guidelines. | |

Best practice i | 2018 | CTLA4 abolishes interaction between CD28 on T cells and B7 molecules on antigen presenting cells. CTLA4-Ig, abatacept(ABT)was developed as a drug with multipotent inhibitor against activated T/B cells, monocytes, dendritic cells, macrophages and osteoclast progenitors expressing B7 molecules. In phase â…¢ RCTs, clinical effects of ABT have been established in MTX-naive, MTX-IR and TNF inhibitor-IR patients with RA. Moreover, in head-to head comparison with representative TNF inhibitors, ABT exerted compatible clinical effect. In clinical practice, ABT is recognized as a biological DMARD with good safety profile. Reduction or withdrawal of ABT is also proposed in patients who achieved remission under treatment with ABT+MTX. In conclusion, ABT can be included in the treatment strategy of RA with wide clinical variance. |
