21091275 | Ultrasonography shows significant improvement in wrist and ankle tenosynovitis in rheumato | 2011 May | OBJECTIVE: Tenosynovitis is common in rheumatoid arthritis (RA) but knowledge is limited regarding its response to anti-inflammatory treatment. This study used ultrasonography (US) to examine the distribution and responsiveness of tenosynovitis to anti-tumour necrosis factor (anti-TNF) treatment in RA patients. METHODS: Twenty patients with RA were examined at baseline and 1, 3, 6, and 12 months after starting adalimumab treatment, and grey-scale (GS) and power Doppler (PD) US scoring (semi-quantitative range 0-3) of wrist and ankle tendons was performed in addition to assessment of the 28-joint Disease Activity Score (DAS28), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR). RESULTS: The extensor carpi ulnaris (ECU) tendon in the wrists and the closely related tendons tibialis posterior (TB) and flexor digitorum longus (FDL) in the ankles were most often inflamed. Median sum scores for this reduced number of tendons at baseline/12-month follow-up were 5/0.5 for GS (p < 0.001) and 4/0 for PD (p < 0.05), with reductions in the US scores during follow-up as large as those found for sum scores of all tendons. The standardized response means (SRMs) for sum GS or PD scores of the reduced number of tendons were higher (range -0.53 to -0.93) than for the sum scores of all tendons (-0.23 to -0.74), and showed larger responsiveness than CRP (-0.10 to -0.43) and ESR (-0.03 to -0.71). CONCLUSION: Bilateral assessments of ECU, TB, and FDL tendons were as sensitive to change as the sum scores of all tendons, and scoring of this reduced number of tendons is suggested to be included in US scorings for follow-up of RA patients. | |
19906007 | Association of mean platelet volume with hypertension in rheumatoid arthritis. | 2010 Mar | Rheumatoid arthritis (RA) is one of the most common chronic inflammatory disorders associated with enhanced cardiovascular morbidity and mortality. Established high prevalence of classical cardiovascular risk factors may only partly explain cardiovascular phenomenon in this disease. Emerging risk factors, markers of inflammation and prothrombotic state such as platelet size are believed to reflect activity of RA. We aimed to study mean platelet volume (MPV) in a cohort of patients with RA and to clarify possible effects of classical cardiovascular and RA-associated risk factors on MPV. Demographic, clinical and a wide range of laboratory parameters, including MPV and platelet count, were obtained for 400 RA patients. Platelet size and count were also assessed in 360 non-RA controls from the local population. We found significantly increased MPV in RA patients compared with controls (P=0.001). The difference retained significant after adjustment for age and sex. High values of MPV (>or=10.7 femtoliter [fL]) were more frequent in RA patients than in controls (21% vs. 9.2%; P<0.0001). In RA patients, blood pressure greater than 140/90 mmHg was associated with high levels of MPV (Odds Ratio [OR] 2.2, 95% Confidence Interval [CI] 1.3-3.7; P=0.003). It is possible that MPV as a surrogate marker of platelet function reflects enhanced vascular risk. To further explore the role of MPV as a marker for cardiovascular risk in RA, prospective studies are warranted. | |
19894782 | Certolizumab pegol: in rheumatoid arthritis. | 2009 | Certolizumab pegol is a PEGylated humanized Fab' monoclonal antibody that targets and neutralizes both membrane-bound and soluble tumor necrosis factor (TNF)-alpha, preventing inflammation and consequently the destruction of cartilage and bone. Certolizumab pegol has a relatively long elimination half-life of approximately 2 weeks, allowing subcutaneous administration once every 2 or 4 weeks. In two randomized, phase III trials in patients with active rheumatoid arthritis despite previous methotrexate therapy (RAPID 1 and 2), the combination of subcutaneous certolizumab pegol 400 mg at weeks 0, 2, and 4, followed by a 200 or 400 mg dose every 2 weeks and a stable dosage of methotrexate, was more effective than placebo plus methotrexate for improving the signs and symptoms of arthritis at weeks 24 (RAPID 1 and 2) and 52 (RAPID 1), according to American College of Rheumatology (ACR) criteria. Improvements in ACR response rates were seen as early as 1 week and at all timepoints measured up to 52 weeks. In RAPID 1 and RAPID 2, radiographic progression was also significantly inhibited with certolizumab pegol plus methotrexate treatment compared with placebo and methotrexate according to van der Heijde modified Total Sharp Scores at 24 and 52 weeks after treatment initiation. In patients with active rheumatoid arthritis who had previously failed to respond to treatment with > or = 1 disease-modifying anti-rheumatic drug, certolizumab pegol 400 mg every 4 weeks as monotherapy effectively improved ACR responses at all measured timepoints up to 24 weeks, according to data from the randomized, phase III FAST4WARD trial. Certolizumab pegol was generally well tolerated in combination with methotrexate or as monotherapy in phase III trials in patients with rheumatoid arthritis, with most adverse events being of mild to moderate intensity. Infections were the most frequently reported adverse events. | |
20635549 | Medication information leaflets for patients: the further validation of an analytic lingui | 2009 | While clinicians may routinely use patient information leaflets about drug therapy, a poorly conceived leaflet has the potential to do harm. We previously developed a novel approach to analysing leaflets about a rheumatoid arthritis drug, using an analytic approach based on systemic functional linguistics. The aim of the present study was to verify the validity of the linguistic framework by applying it to two further arthritis drug leaflets. The findings confirmed the applicability of the framework and were used to refine it. A new stage or 'move' in the genre was identified. While the function of many of the moves appeared to be 'to instruct' the patient, the instruction was often unclear. The role relationships expressed in the text were critical to the meaning. As with our previous study, judged on their lexical density, the leaflets resembled academic text. The framework can provide specific tools to assess and produce medication information leaflets to support readers in taking medication. Future work could utilize the framework to evaluate information on other treatments and procedures or on healthcare information more widely. | |
20062998 | Effect of etanercept and entecavil in a patient with rheumatoid arthritis who is a hepatit | 2012 Apr | In this report, we describe a case of a 48-year-old Japanese woman who is a hepatitis B (HB) carrier with rheumatoid arthritis (RA). She had the following antibody profile: HBs Ag(+), HBs Ab(-), HBe Ag(-), HBe Ab (+), HBc Ab(-) and undetectable HBV-DNA level. She was treated with auranofin, salazosulfapyridine, and bucillamine. Finally, she was treated with D: -penicillamine, but her disease activity remained elevated. Prophylactic treatment of entecavir 0.5 mg daily was started in March 2008 and all disease-modifying anti-rheumatic drugs were stopped. After 2 weeks, etanercept monotherapy was started at 25 mg subcutaneously once a week. Significant improvement in clinical parameters of disease activity and well being was observed. Serum alanine aminotransferase (ALT), serum aspartate aminotransferase (AST), and HB virus viral load did not change significantly. Serum ALT, AST, and HB virus viral load were followed-up at every 3-month intervals, from initiation of therapy up to 24 months after the start of treatment with etanercept. We have also summarized the course of nine RA patients who received etanercept and were HB carriers or had chronic HB according to our literature search. Based on the results of our study, treatment of these patients with etanercept co-administered with lamivudine or entecavir appears to be safe. | |
20663972 | Rheumatoid arthritis of the hand: monitoring with a simplified MR imaging scoring method-- | 2010 Sep | PURPOSE: To assess a simplified scoring method (Simplified Rheumatoid Arthritis Magnetic Resonance Imaging Score [SAMIS]) developed to shorten interpretation time, while retaining both correlation with Rheumatoid Arthritis Magnetic Resonance Imaging Score (RAMRIS) and same or better intra- and interreader reliability. MATERIALS AND METHODS: Ethics board approval and written patient consent were obtained. The study was HIPAA compliant. Thirty-eight patients with rheumatoid arthritis and 20 patients with no or early unclassified arthritis underwent magnetic resonance imaging of both wrists and hands. RAMRIS was used to evaluate erosions (scale, 0-10), edema (scale, 0-3), and synovitis (scale, 0-3). SAMIS assessed only one hand and was based on the radiographic Simple Erosion Narrowing Score, thus reducing the number of study areas from 116 to 36. Erosions were scored with a scale from 1 to 10. Edema and synovitis were, respectively, scored with scales from 0 to 1 and 0 to 2. SAMIS correlation with RAMRIS was tested by using the Spearman test. Last, the intra- and interobserver reproducibility of both scores were calculated. RESULTS: SAMIS was closely correlated with RAMRIS for the entire series (r = 0.91, 0.79, and 0.94, respectively, for erosion, edema, and synovitis), as well as in patients with rheumatoid arthritis (r = 0.93, 0.81, and 0.92) and those with no or unclassified arthritis (r = 0.83, 0.73, and 0.94). The time needed to assess examination results with RAMRIS ranged from 5 to 20 minutes (13 minutes +/- 3.90 [standard deviation]), whereas it ranged from 2 to 7 minutes (5 minutes +/- 1.45) with SAMIS. For each of the three features (erosion, edema, and synovitis), intraobserver agreement (RAMRIS: kappa = 0.67, 0.94, 0.81, respectively; SAMIS: kappa = 0.66, 1.0, 0.91) and interobserver agreement (RAMRIS: kappa = 0.61, 0.58, 0.74, respectively; SAMIS: kappa = 0.59, 0.81, 0.81) were good to excellent. CONCLUSION: This simplified reproducible scoring scheme could be used to monitor joint damage in rheumatoid arthritis. (c) RSNA, 2010. | |
20046013 | [Role of T-cell leukemia translocation-associated gene (TCTA) protein in human osteoclasto | 2009 Dec | Synovial tissues of patients with rheumatoid arthritis (RA) include factors regulating bone resorption, such as receptor activator NF-kappaB ligand (RANKL), TNF-alpha, IL-6, IL-17, and IFN-gamma. However, in addition to these cytokines, other factors expressed in synovial tissues may play a role in regulating bone resorption. In 2009, we demonstrated that novel peptides from T-cell leukemia translocation-associated gene (TCTA) protein expressed in synovial tissues from patients with RA inhibit human osteoclastogenesis, preventing cellular fusion via the interaction between TCTA protein and a putative counterpart molecule. Only a few studies on the role of TCTA protein have been reported, including our report published in 2009. In the current review paper, we summarized papers on TCTA protein before 2009 and our recent findings. | |
20439288 | Synovial tissue hypoxia and inflammation in vivo. | 2010 Jul | INTRODUCTION: Hypoxia is a microenvironmental feature in the inflamed joint, which promotes survival advantage for cells. The aim of this study was to examine the relationship of partial oxygen pressure in the synovial tissue (tPO(2)) in patients with inflammatory arthritis with macroscopic/microscopic inflammation and local levels of proinflammatory mediators. METHODS: Patients with inflammatory arthritis underwent full clinical assessment and video arthroscopy to quantify macroscopic synovitis and measure synovial tPO(2) under direct visualisation. Cell specific markers (CD3 (T cells), CD68 (macrophages), Ki67 (cell proliferation) and terminal deoxynucleotidyl transferase dUTP nick end labelling (cell apoptosis)) were quantified by immunohistology. In vitro migration was assessed in primary and normal synoviocytes (synovial fibroblast cells (SFCs)) using a wound repair scratch assay. Levels of tumour necrosis factor alpha (TNFalpha), interleukin 1beta (IL1beta), interferon gamma (IFNgamma), IL6, macrophage inflammatory protein 3alpha (MIP3alpha) and IL8 were quantified, in matched serum and synovial fluid, by multiplex cytokine assay and ELISA. RESULTS: The tPO(2) was 22.5 (range 3.2-54.1) mm Hg and correlated inversely with macroscopic synovitis (r=-0.421, p=0.02), sublining CD3 cells (-0.611, p<0.01) and sublining CD68 cells (r=-0.615, p<0.001). No relationship with cell proliferation or apoptosis was found. Primary and normal SFCs exposed to 1% and 3% oxygen (reflecting the median tPO(2) in vivo) induced cell migration. This was coupled with significantly higher levels of synovial fluid tumour necrosis factor alpha (TNFalpha), IL1beta, IFNgamma and MIP3alpha in patients with tPO(2) <20 mm Hg (all p values <0.05). CONCLUSIONS: This is the first study to show a direct in vivo correlation between synovial tPO(2), inflammation and cell migration, thus it is proposed that hypoxia is a possible primary driver of inflammatory processes in the arthritic joint. | |
20127397 | Optimal care for rheumatoid arthritis: a focus group study. | 2010 Jun | Our study sought to identify barriers to optimal care for individuals with rheumatoid arthritis (RA). Our study was set in a population with universal access to comprehensive health care in the context of a university hospital health network. Using purposive sampling, we invited RA patients, health professionals, and decision makers from urban and rural regions to participate in structured focus group interviews. Content analysis was performed to determine themes emerging from the data. We identified four general themes. First, initial barriers to optimal care for people begin before primary care contact, at the level of the general population and/or related to primary care access. Second, many factors (at the patient, physician, and system level) influenced how quickly a patient is referred from primary to specialty care. Third, after referral, multiple comanagement issues influence patient outcomes. Fourth, optimizing RA care requires adequate resources. Participants emphasized the need for more education (of patients, of health care providers, and within the general community), better communication between and among patients and health care providers, and more efficient use of existing resources. Our work provides insights regarding barriers to and facilitators of optimal care in RA. Further work with these stakeholder groups in our health care region will examine potential solutions and the feasibility of their implementation. Our work provides an example of how research can assist stakeholder leaders in creating structured and incremental plans to improve health care delivery for persons with chronic diseases like RA. | |
20638217 | Translating patient education theory into practice: developing material to address the car | 2011 Jul | OBJECTIVE: This paper describes the rationale and design of a theory-informed patient education programme addressing cardiovascular disease for people with rheumatoid arthritis (RA) to illustrate how theory can explicitly be translated into practice. METHODS: A steering group of rheumatologists and psychologists was convened to design the programme. The Common Sense Model, the Theory of Planned Behaviour and the Stages of Change Model were used to underpin the topics and activities in the programme. User involvement was sought. The programme was formatted into a manual and the reading age of the materials was calculated. RESULTS: A small group 8-week programme was designed. The structure of the patient education programme, including topics, underlying psychological theory as well as behaviour change techniques, is described. CONCLUSION: This patient education programme addresses a currently unmet educational need for patients with RA and uses theory to design, not just evaluate, the programme. This will allow both enhanced interpretation of the results when the programme is implemented and replication by other units if successful. PRACTICE IMPLICATIONS: The actual design and detail of education programmes merit wider dissemination to facilitate progress in the process of development and application. | |
19517491 | 'Extra information a bit further down the line': rheumatoid arthritis patients' perception | 2009 Dec | OBJECTIVE: There are no patient education programmes addressing the increased risk of cardiovascular disease (CVD) associated with rheumatoid arthritis (RA). This is the second in a pair of studies exploring stakeholder perceptions of developing such educational material. Healthcare professionals' perceptions were explored in the first study; here, we explore the perceptions of people with RA. METHODS: Semi-structured interviews were held individually with 18 people with RA, purposively sampled to include participants with no co-morbid history of CVD, those with CVD risk factors and those who had experienced a CVD event. The interview transcripts were analysed using interpretative phenomenological analysis. RESULTS: Four superordinate themes were identified: experiences of living with RA; reactions to learning about co-morbid CVD; implementing lifestyle changes; and expectations of education. Participants found being diagnosed with RA a devastating experience and were mostly unaware of their increased risk of CVD co-morbidity. They explained how information about CVD would be overwhelming and irrelevant at diagnosis, but they would have coped with 'extra information a bit further down the line'. CONCLUSION: There is a need to develop educational material or programmes. Their design must consider factors which facilitate lifestyle change, such as motivation or receiving personalized advice, and factors that inhibit change, such as depression or fatalism. Emphasizing the positive effects that some CVD lifestyle changes may have on RA symptom control may be particularly persuasive. Group education would be a popular format. These findings can be directly translated into clinical practice. | |
19951395 | Utility of synovial biopsy. | 2009 | Synovial biopsies, gained either by blind needle biopsy or minimally invasive arthroscopy, offer additional information in certain clinical situations where routine assessment has not permitted a certain diagnosis. In research settings, synovial histology and modern applications of molecular biology increase our insight into pathogenesis and enable responses to treatment with new therapeutic agents to be assessed directly at the pathophysiological level. This review focuses on the diagnostic usefulness of synovial biopsies in the light of actual developments. | |
20396720 | Effect of combination of anticytokine preparations anaferon and artrofoon on immune inflam | 2009 Sep | Treatment with a combination of artrofoon and anaferon significantly reduced clinical and laboratory parameters of rheumatoid inflammation and significantly decreased the content of antiinflammatory cytokines in the blood. These findings attest to antiinflammatory and immunomodulating effects of these preparations. | |
19796372 | Anticitrullinated protein/peptide antibodies and rheumatoid factors: two distinct autoanti | 2009 | In a previous issue of Arthritis Research and Therapy, Ursum and colleagues report the relative stabilities of anticitrullinated protein/peptide antibodies (ACPAs) and IgM rheumatoid factors during the course of rheumatoid arthritis and their differential correlation with markers of the acute-phase response. These findings add to a growing body of evidence highlighting the distinct nature of these two autoantibody systems and the role of ACPAs as a disease-specific marker of rheumatoid arthritis. | |
19933783 | Type I interferons have no major influence on humoral autoimmunity in rheumatoid arthritis | 2010 Jan | OBJECTIVE: Type I IFNs have recently been implicated in autoantibody-mediated diseases such as SLE. As half the RA patients display a type I IFN(high) signature, we investigated in a pilot study if type I IFN determines the autoantibody response in RA. METHODS: Serum and peripheral blood cells were obtained from 52 RA patients, with paired samples before and after infliximab treatment in 21 patients. Additional samples were collected from 8 anti-citrullinated protein antibody (ACPA)-positive individuals without arthritis and from 10 ACPA-negative healthy controls. The type I IFN signature was determined by peripheral blood cell gene expression analysis and quantitative RT-PCR. ACPA IgG and IgM, RF IgM, anti-nucleosome IgM and anti-dsDNA were measured by ELISA. RESULTS: The type I IFN signature was not related to the presence and titers of ACPA and RF during active disease. TNF blockade induced a similar rise of ANAs, and a similar decrease in RF titers in both groups. ACPA IgG and IgM levels appeared to be down-modulated only in the type I IFN(low) group. These changes were independent of the changes in type I IFN response gene activity after TNF blockade. Furthermore, the ACPA response in individuals without arthritis and inflammation was not related to an increase of type I IFN. CONCLUSIONS: In this explorative study, type I IFN signature does not appear to have a major impact on the humoral autoimmune response in RA. Replication of these data remains warranted. | |
20309863 | Does pregnancy provide vaccine-like protection against rheumatoid arthritis? | 2010 Jul | OBJECTIVE: Previous studies have evaluated the correlation between rheumatoid arthritis (RA) risk and pregnancy history, with conflicting results. Fetal cells acquired during pregnancy provide a potential explanation for modulation of RA risk by pregnancy. The present study was undertaken to examine the effect of parity on RA risk. METHODS: We examined parity and RA risk using results from a population-based prospective study in Seattle, Washington and the surrounding area and compared women who were recently diagnosed as having RA (n = 310) with controls (n = 1,418). We also evaluated the distribution of parity in cases according to HLA genotype. RESULTS: We found a significant reduction of RA risk associated with parity (relative risk [RR] 0.61 [95% confidence interval 0.43-0.86], P = 0.005). RA risk reduction in parous women was strongest among those who were younger. Most striking was that RA risk reduction correlated with the time that had elapsed since the last time a woman had given birth. RA risk was lowest among women whose last birth occurred 1-5 years previously (RR 0.29), with risk reduction lessening progressively as the time since the last birth increased (for those 5-15 years since last birth, RR 0.51; for those >15 years, RR 0.76), compared with nulliparous women (P for trend = 0.007). No correlation was observed between RA risk and either age at the time a woman first gave birth or a woman's total number of births. Among cases with the highest genetic risk of RA (i.e., those with 2 copies of RA-associated HLA alleles), a significant underrepresentation of parous women versus nulliparous women was observed (P = 0.02). CONCLUSION: In the present study, there was a significantly lower risk of RA in parous women that was strongly correlated with the time elapsed since a woman had last given birth. While the explanation for our findings is not known, HLA-disparate fetal microchimerism can persist many years after a birth and could confer temporary protection against RA. | |
19579213 | Aerobic capacity in patients with rheumatoid arthritis: a comparison of two submaximal tes | 2009 Dec | BACKGROUND: In a clinical setting it is important to evaluate aerobic capacity in individuals with rheumatoid arthritis (RA) and to have a choice between tests, owing to disability of varying severity. Two submaximal tests, a bicycle ergometer test and a treadmill walking test, are commonly used. Despite expected differences in the results, these tests have been used interchangeably. The aim of the current study was to compare the results of the two tests, the size of the difference and factors expected to influence the results. METHODS: Fifty-two outpatients with RA performed the two tests. Agreement and correlations between the results of the tests were calculated. Multivariate analysis was used to study the relationships between gender, weight, health assessment questionnaire, global health assessment and the difference between the tests. RESULTS: Sixty per cent of the subjects exhibited a higher estimated value of maximum oxygen uptake (VO(2max)) in the treadmill test. The limits of agreement for the estimated VO(2max) values between the two methods ranged from -13.4 to +18.4 ml x min(-1) x kg(-1), and the intraclass correlation coefficient (ICC(Two-way mixed)) was 0.34 (95% confidence interval [CI] 0.07, 0.56). Body weight was independently associated with the difference between the two tests (regression coefficient 0.3; 95% CI 0.14, 0.42). A higher body weight had a greater impact on the results of the bicycle test (R(2) = 0.28; regression coefficient -0.3; 95% CI -0.47, -0.17) than on the treadmill walking test (R(2) = 0.02; regression coefficient -0.06; 95% CI -0.14, 0.03). CONCLUSIONS: It is not advisable to use the two submaximal methods interchangeably. Weight influenced the difference between the two tests, and to a higher degree in the bicycle test than the treadmill walking test. | |
18991190 | Sustained improvement of vascular endothelial function during anti-TNFalpha treatment in r | 2009 Jan | OBJECTIVES: Vascular endothelial function and common carotid artery intima-medial thickness (CCA-IMT) are well-established surrogate markers for early atherosclerotic disease, which accounts for 30-40% of excess mortality in rheumatoid arthritis (RA) patients. Our aim was to investigate whether long-term treatment with anti-tumour necrosis factor (TNF)alpha agents can modulate endothelial function and CCA-IMT. METHODS: Twelve patients with RA (mean age 54.8+/-15 years) on anti-TNFalpha treatment (seven adalimumab, five infliximab) due to uncontrolled disease activity, with mean Disease Activity Score (DAS28) 5.7 (range 4.6-6.9) despite disease-modifying anti-rheumatic drugs (DMARDs), were studied prospectively. Patients were assessed at baseline and after 3 and 18 months for endothelial-dependent vasodilatation, assessed by flow-mediated vasodilatation (FMD), endothelial-independent vasodilatation and CCA-IMT. RA disease activity and response to therapy were assessed by the DAS28 index. RESULTS: After 18 months of treatment, 67% of the patients were responders according to European League Against Rheumatism (EULAR) response criteria. Anti-TNFalpha treatment improved FMD (from 7+/-4.3% to 11.1+/-3.8%, p = 0.026) whereas CCA-IMT did not change significantly [from 0.67 (0.4-1) to 0.68 (0.39-1.2) mm; mean change 0.01 (-0.06 to 0.08) mm]. Endothelial-independent vasodilatation remained stable (20.4+/-7.3% to 22.9+/-6.5%, p = 0.4). CONCLUSIONS: In this small cohort of patients with RA and no clinically overt cardiovascular disease (CVD), after 18 months of treatment with anti-TNFalpha agents, endothelial function improved significantly while CCA-IMT remained stable. Longitudinal studies using more patients are needed to determine the clinical significance of these findings in relation to the risk of atherosclerosis. | |
20535511 | Pathology associated to the Baker's cysts: a musculoskeletal ultrasound study. | 2010 Sep | The purpose of this study was to know the pathology associated with Baker's cyst (BC) in a rheumatology clinic and to evaluate the incidence, characteristics, and complications of BC. We reviewed the rheumatology ultrasound laboratory charts of patients with BC from Oct 2006 through Dec 2008. Demographic and disease data were also collected. Of the 1,120 patients who underwent ultrasound studies, 145 (12.9%) were found to have 180 BCs. The associated diseases were as follows: 91 (50.6%) osteoarthritis (OA) of the knee, 37 (20.6%) rheumatoid arthritis (RA), 25 (13.9%) gout, 14 (7.8%) seronegative spondyloarthropathy (SpA), and 13 (7.2%) pyrophosphate arthropathy. We found ruptured BCs in 12 patients, whose associated pathologies were in the following: four RA, four OA of the knee, two gout, one SpA, and one pyrophosphate arthropathy. The most frequent associated arthropathy of BCs was OA (50.6%), followed by RA (20.6%). However, in the cases of ruptured BC, the inflammatory pathology (66.7%) is more frequent than the degenerative one (33.3%). | |
19227955 | [Effectiveness of TNF antagonists in routine clinical practice and costs]. | 2009 Jan | A comparison of effectiveness of TNF antagonists adalimumab, infliximab and etanercept in the treatment of rheumatoid arthritis (RA) was made, which was derived from studies provided abroad based on routine clinical practice. The calculation of cost-effectiveness of each TNF antagonist for Czech Republic was made on the basis of Dutch DREAM registry of patients with RA (Kiewit et al, 2008). The prices of therapy of all three TNF antagonists are similar in the first year of treatment of patients with average weight, in the second year the price of infliximab is lower, but only in the case of patients where the doses do not reach 4 amp. of infliximab. Clinical effectiveness was evaluated in DAS28 and HAQ units. Cost-effectiveness of all TNF antagonists was similar, when 2 amp. of infliximab per dose phycician considered sufficient, but when patients were given higher doses of infliximab the trend to lower cost-effectiveness of infliximab compared to adalimumab and etanercept was observed. |
