21305296 Evaluation of disease activity indices in Korean patients with rheumatoid arthritis. 2012 Feb The aim of this study is to examine the validity of the rheumatoid arthritis (RA), disease activity score (DAS), 28-C-reactive protein (CRP), the simplified disease activity index (SDAI), and the clinical disease activity index (CDAI) against the DAS28-erythrocyte sedimentation rate (ESR) and determine cut-off values for each tool in Korean patients with RA. A total of 223 RA patients were consecutively recruited from the Hanyang University Hospital for Rheumatic Diseases in Seoul, Korea. DAS28-CRP, SDAI, and CDAI were measured and compared with DAS28-ESR. The correlation coefficients of DAS28-ESR with DAS28-CRP, SDAI, and CDAI were 0.93, 0.85, and 0.84, demonstrating strong linear relationships. The cut-off values of DAS28-CRP classifying RA patients into four categories of disease activity were defined as 2.19, 2.60, and 4.07. SDAI cut-off values were defined as 3.75, 7.50, and 16.88. CDAI cut-off values were defined as 3.62, 7.38, and 16.50. DAS28-CRP, SDAI, and CDAI are valid and sensitive assessment indices of disease activity that are comparable to DAS28-ESR. The cut-off values of each tool derived in this study might be useful for routine monitoring and therapeutic decision-making in Korean RA patients.
23271425 Major trends in the manifestations and treatment of rheumatoid arthritis in a multiethnic 2013 Jul We analyzed the epidemiological changes of rheumatoid arthritis (RA) over three decades using patients from a single center in Singapore. All patients who fulfill the 1987 American College of Rheumatology criteria for RA were invited to enroll in a prospective disease registry. We analyzed the patient demographics, disease manifestation, management and patient-reported outcomes, including quality of life (QoL), in the three categories according to the year of disease onset: before 1989 (group I), 1990-1999 (group II) and after 2000 (group III). There were 1,153 patients with 231, 532 and 390 in groups I, II and III, respectively. The mean disease durations were 25, 12 and 4.8 years, respectively. The majority was female (84.1 %) and Chinese (76.6 %) with no socio-demographic differences across the three periods. The age of onset rises and the prevalence of rheumatoid factor falls with the proximity of disease onset. Patients with most recent disease onset had the earliest access to the rheumatologist. They also had the highest tender and swollen joint counts, lowest deformed joint count and highest remission rate. Patients in group I report better mental and emotional QoL though many developed marked disability. We have documented changes of the manifestations of RA that are dependent and independent of improved treatment. Significant differences in accessibility to the rheumatologist, RA activity, functional capacity, quality of life and comorbidities were seen in subsequent cohorts due to treatment evolution and more efficient healthcare delivery.

21340502 Hemophagocytic syndrome in a patient with rheumatoid arthritis. 2011 Oct A 76-year-old man with rheumatoid arthritis, who had been treated with oral prednisolone and methotrexate, presented with high fever and generalized fatigability. Laboratory data demonstrated marked pancytopenia, which we first regarded as a side effect of methotrexate, and leucovorin was administered with granulocyte-colony stimulating factor and transfusions. Because no recovery was recognized, however, bone marrow aspiration was performed, by which hemophagocytic syndrome was diagnosed. After corticosteroid pulse therapy was initiated, the patient's symptoms were rapidly attenuated and laboratory data rapidly normalized.
23136037 Synovitis--an inflammation of joints destroying the bone. 2012 This article is to share some of the key scientific insights made by Dr Barry Bresnihan in rheumatoid arthritis. Dr Bresnihan elaborated new and visionary concepts in arthritis research, which still influence current thinking. He had been particularly dedicated to investigate the inflammatory tissue (synovitis) in RA, which he considered as a clue to understand the pathogenesis of this disease. He thereby pioneered the concept of synovial biopsy as a technique, which allows to directly analyse synovitis and has stimulated many other rheumatologists in joining his efforts. He was also dedicated to understand why synovitis triggers bone destruction in joints and started to work on defining the molecular interactions between inflammation and the bone. This article picks up some of the major insights achieved by Dr Bresnihan's work and how these findings influenced today's understanding of arthritis.
22546069 The cost of care of rheumatoid arthritis and ankylosing spondylitis patients in tertiary c 2012 Mar OBJECTIVES: To determine the direct and indirect costs due to rheumatoid arthritis (RA) and ankylosing spondylitis (AS) patients in Turkey. METHODS: An expert panel was convened to estimate the direct and indirect costs of care of patients with RA and AS in Turkey. The panel was composed of 22 experts chosen from all national tertiary care rheumatology units (n=53). To calculate direct costs, the medical management of RA and AS patients was estimated using 'cost-of-illness' methodology. To measure indirect costs, the number of days of sick leave, the extent of disability, and the levels of early retirement and early death were also evaluated. Lost productivity costs were calculated using the 'human capital approach', based on the minimum wage. RESULTS: The total annual direct costs were 2,917.03 Euros per RA patient and 3,565.9 Euros for each AS patient. The direct costs were thus substantial, but the indirect costs were much higher because of extensive morbidity and mortality rates. The total annual indirect costs were 7,058.99 Euros per RA patient and 6,989.81 for each AS patient. Thus, the total cost for each RA patient was 9,976.01 Euros and that for an AS patient 10,555.72 Euros, in Turkey. CONCLUSIONS: From the societal perspective, both RA and AS have become burden in Turkey. The cost of lost productivity is higher than the medical cost. Another important conclusion is that indirect costs constitute 70% and 66% of total costs in patients with RA and AS, respectively.
21351367 Patient-reported events preceding the onset of rheumatoid arthritis: possible clues to aet 2011 Mar AIMS: Patients with rheumatoid arthritis (RA) often report events that they believe may have caused their disease. We attempted to characterize such causal events and the possible relationship between these and outcomes. METHODS: Between 1996 and 2004, 1,787 adult patients were included in the Better Anti-Rheumatic FarmacOTherapy (BARFOT) early RA study in Sweden. Six possible causal events at baseline were predefined. Disease Activity Score 28-joint count (DAS28) and treatment were registered at inclusion and at three, six and 12 months. The European League against Rheumatism (EULAR) response criteria were used. RESULTS: A total of 1,652 patients (92%) answered the question about possible causal events. Thirty per cent (490) of the patients believed that some event in particular had caused their RA. Sixteen per cent of the patients thought that infection, 4.4% psychological trauma, 4.1% physical trauma, 2.8% surgery, 1.5% pregnancy and 1.2% vaccination had been the cause. Younger patients attributed previous infection to their RA more often than older patients. There were no differences in EULAR response up to one year between patients who reported some event or infection and patients who did not. RA thought to be caused by infection showed a seasonal trend in the month of onset. Women reported that trauma had been a cause of their RA more often than men. CONCLUSION: Thirty per cent of the patients reported some causal event and 16% reported infection to be the cause of their RA. There were differences in gender and age in what patients reported as the cause of their RA.
23022221 Influence of the structure of mood in the assessment of rheumatoid arthritis through the v 2012 Nov OBJECTIVE: To analyze the effect of the structure of mood over the following assessment tools for rheumatoid arthritis: visual analog scale (VAS) for pain, HAQ and DAS28. PATIENTS AND METHODS: We studied 86 patients with recent onset rheumatoid arthritis, of which 75.7% were female, with a mean age at disease onset of 55 years. All patients were administered the Spanish version of the PANAS questionnaire that evaluates the components of positive (PA) and negative mood (AN). Patients belonged to the registry of new-onset arthritis in our center so clinical information was available for 282 patients visits. To determine the effect of PA and AN on each of the dependent variables we performed three multivariate linear regression models using generalized linear models through the Stata glm command 10.1. RESULTS: The mean score for PA and AN in our patients was similar to that described for the healthy Spanish population. The high scores on the subscale of AN were associated with worse scores in both the VAS for pain and the HAQ. By contrast, high scores on PA were associated with better outcomes of disease activity measured by DAS28. CONCLUSION: The structure of mood may influence the tools we use for evaluating patients with rheumatoid arthritis, so it might be advisable to include the PANAS questionnaire as part of that assessment.
22002015 Mannose-binding lectin gene polymorphisms in Brazilian patients with rheumatoid arthritis. 2012 Jan OBJECTIVE: Rheumatoid arthritis (RA) is a disease with unknown etiology but it is probably multifactorial. RA susceptibility is related to genetic, hormonal, immunologic, and environmental factors. Mannose-binding lectin (MBL) is an important protein of the human innate immune system, encoded by the MBL2 gene. Polymorphisms in MBL2 were associated with several diseases, and may be an important factor in RA susceptibility. We analyzed 3 MBL2 gene polymorphisms in 322 Brazilian patients with RA and 345 ethnically matched healthy controls. METHODS: MBL2 gene variants were analyzed through polymerase chain reaction sequencing. RESULTS: Considering MBL2 B, C, and D alleles separately, a significant difference in both genotypic and allelic frequencies, particularly concerning frequency of the C allele, was observed comparing European-derived and African-derived individuals (European-derived patients 0.022 vs African-derived patients 0.205; European-derived controls 0.029 vs African-derived controls 0.144; both p < 0.001). We also analyzed MBL2 genotype in relation to extraarticular manifestations. Considering MBL2 variants together, we found an increased frequency of the OO genotype among patients with rheumatoid nodules (p = 0.031), although this association lost significance after Bonferroni correction. CONCLUSION: Our findings suggest an association of MBL2 genotypes with some clinical manifestations of RA, but more studies are needed to clarify the actual role of MBL in RA.
22467921 Effect of rheumatoid arthritis on volumetric bone mineral density and bone geometry, asses 2012 Jun OBJECTIVE: To investigate the effect of rheumatoid arthritis (RA) on volumetric bone mineral density (vBMD) and bone geometry in postmenopausal women treated with bisphosphonates. METHODS: Fifty-three postmenopausal women with RA and 87 control subjects, comparable in terms of age, body mass index, and years since menopause, underwent peripheral quantitative computed tomography (pQCT) of the nondominant tibia. RESULTS: At 4% (trabecular site), trabecular bone mineral content (BMC) and vBMD (p < 0.001) were lower in the RA group, while trabecular area was comparable. At 38% (cortical site), cortical BMC (p < 0.01), area (p < 0.05), and thickness (p < 0.001) were lower in the RA group, whereas vBMD was comparable. Endosteal circumference was higher (p < 0.05), whereas periosteal circumference was comparable, indicating cancellization of cortical bone. In the RA group, muscle area was lower (p < 0.001), while at 14% polar stress strength index was significantly lower (p < 0.01) in patients with RA, indicating impairment of bone mechanical properties. CONCLUSION: RA is associated with negative effects on both cortical and cancellous bone in postmenopausal women treated with bisphosphonates. Cortical geometric properties are also adversely affected mainly by increased endosteal circumference, whereas trabecular geometric properties are generally preserved.
21901351 Magnetic resonance imaging of rheumatoid meningitis: a case report and literature review. 2012 Nov Rheumatoid meningitis is a rare and serious complication of rheumatoid arthritis (RA) with high mortality rate. Clinical importance of the disease is high because diagnosis is difficult, and the disease is treatable if diagnosed successfully. We present the clinical and cranial magnetic resonance imaging findings of 62-year-old female patient with RA who has been followed up for 4 years.
21593366 Five to ten-year outcomes of the Universal total wrist arthroplasty in patients with rheum 2011 May 18 BACKGROUND: Implant arthroplasty of the wrist offers pain relief with preservation of motion to patients with rheumatoid arthritis, although few studies have investigated the long-term results of this procedure. The purpose of the present study is to report the prospective results of total wrist arthroplasty with use of the Universal wrist prosthesis in a consecutive series of patients with rheumatoid arthritis who were managed by a single surgeon. METHODS: Twenty-four wrist arthroplasties in twenty patients with rheumatoid arthritis were followed prospectively. Nineteen wrists in fifteen patients were followed clinically and radiographically for a mean of 7.3 years (range, 5.0 to 10.8 years) after the index procedure. Outcome measures included the Disabilities of the Arm, Shoulder and Hand (DASH) score, wrist range of motion, and standard radiographic findings. RESULTS: The average DASH score improved from 62 points preoperatively to 40 points at the time of the latest follow-up. The mean wrist flexion and extension at the time of the latest follow-up were 42° and 20°, respectively, for a mean improvement in the total flexion-extension arc of 14°. A total of nine wrists (45%) in eight patients underwent revision surgery because of a loose carpal component at the time of the latest follow-up. One patient underwent wrist arthrodesis because of recurrent wrist instability. Two additional wrists in two patients had radiographic evidence of carpal component subsidence at the time of the latest follow-up. The implant survival rates at five and seven years for the original prosthetic components were 75% and 60%, respectively. CONCLUSIONS: The results for the Universal wrist prosthesis at a minimum of five years of follow-up include a high rate of failure, most often because of carpal component loosening, resulting in revision of ten (50%) of twenty wrists at the time of the latest follow-up (with the inclusion of one revision in a patient who died before five years). Patients with a stable prosthesis maintained a functional range of motion and had improvement in patient-reported outcome measures.
21175732 Being an outpatient with rheumatoid arthritis--a focus group study on patients' self-effic 2011 Jun BACKGROUND: A Danish study compared three different outpatient settings for persons with rheumatoid arthritis (RA). All participants completed a short course before random allocation to one of three groups. A third of the patients continued with planned medical consultations. A third was allocated to a shared care setting with no planned consultations. The final third was allocated for planned nursing consultations every 3 months. Little knowledge exists of patients' experiences at different outpatient settings. AIMS: (1) To explore the patients' experiences of participation in the course and one of the three different outpatient settings and (2) to explore whether some of these experiences can explain possible changes in self-efficacy beliefs. METHOD: In total six focus group interviews were carried out with 33 participants from the three settings. The interviews and the analysis were inspired by phenomenological philosophy. RESULTS: On the short course the participants felt understood, gained new insights and some changed behaviours after attendance. Important themes in experiences from the three outpatient settings were: (1) continuity and relationships with health professionals, (2) a need for others to take control, and (3) contact with health professionals. SPECIFIC FINDINGS: The nursing consultations were experienced as less factual and less authoritarian than the medical consultations. The participants in the shared care setting had a lack of confidence in the GP's competence to manage their RA. However, they felt responsible for taking action in case of a flare up. The study provided opportunities to enhance the participants' self-efficacy beliefs. CONCLUSION: When planning follow-up care, the focus needs to be on continuity, the interpersonal relationship and easy access to health professionals with thorough knowledge of RA. A short course and consultations with nurses and hospital doctors can enhance patients' self-efficacy and thereby strengthen their confidence to assess and manage their own disease.
22337478 Identifying patient-reported outcomes in rheumatoid arthritis: the impact of foot symptoms 2012 Jun BACKGROUND: The importance of patient-reported outcome measures in healthcare is increasingly recognized but these need to be patient generated. Given that foot symptoms are very common in rheumatoid arthritis (RA), we chose a patient-centred model with which to investigate the patients' perspective on how their foot symptoms affected them as individuals and impacted on their self-perceived quality of life, rather than using the traditional approaches of clinical examination (e.g. prevalence of deformities) or radiological assessments. METHODS: A 33-item self-administered postal questionnaire was sent to all people with RA attending outpatient clinics in three hospitals over the course of one month (n=390). The questionnaire used both quantitative and qualitative approaches to enquire about the nature and extent of foot complaints and how respondents believed this affected their quality of life. RESULTS: In total, 190 usable replies were received (49%). Nearly all respondents (n=177; 93.2%) reported that their quality of life was adversely affected by their foot complaint(s), with over half describing their quality of life as being badly or very badly affected. When asked to rate how severely foot complaints affected their quality of life using a 10 cm visual analogue scale, the mean score was 5.36 (range 0-10 ± SD 3), indicating that foot complaints have a moderate-to-severe effect on quality of life. Those aspects of daily living most significantly affected were: the ability to walk and the ability to wear a variety of shoes. CONCLUSION: This study demonstrated that people with RA focus on different aspects of the impact of their disease to doctors. Rather than foot deformity or ulceration, disease activity score or health assessment questionnaire score, patients were easily able to pinpoint the key negativities of living with RA in their feet and indicated choice of footwear and ability to walk as crucial. This study and similar ones are key to identifying appropriate patient-reported outcome measures.
21455121 Access to biologic treatment for rheumatoid arthritis in Central and Eastern European (CEE 2011 Apr BACKGROUND: The aim of this study was to assess and compare patients' access to biologic anti-RA drugs in selected Central and Eastern European (CEE) countries and to analyze the determinants of differences between countries. MATERIAL/METHODS: This is a multi-country survey study, based on a combination of desk research and direct contact with national RA stakeholders. Data was collected using a pre-defined questionnaire. Affordability was measured using an affordability index, calculated comparing the index of health care expenditures to the price index, using Poland as an index of 1. RESULTS: The percentage of patients on biologic treatment in 2009 was highest in Hungary (5% RA patients on biologic treatment), followed by Slovenia (4.5%), Slovakia (3.5%), Czech Republic (2.92%), Romania (2.2%), Estonia (1.8%), and Croatia, Serbia, Poland (below 1.5%). Infliximab, etanercept, adalimumab and rituximab were included in the reimbursement system in all countries, but abatacept and tocilizumab were included only in Slovakia. In Slovenia, public payer covered 75% of the price, and 25% is covered by supplementary health insurance; in Bulgaria public payer covered 50% of etanercept and adalimumab costs, and 75% of rituximab cost. In other countries, biologic drugs are reimbursed at 100%. Affordability index for biologic drugs was the lowest in Slovenia (0.4). In each country national guidelines define which patients are eligible for biologic treatment. Disease Activity Score (DAS28) of over 5.1 and failure of 2 or more disease-modifying anti-RA drugs, including methotrexate, are commonly used criteria. CONCLUSIONS: The most important factors limiting access to biologic anti-RA treatment in the CEE region are macroeconomic conditions and restrictive treatment guidelines.
21343899 Epigenetic alterations in autoimmune rheumatic diseases. 2011 May The potential roles of epigenetic alterations in the pathogenesis of autoimmune rheumatic diseases are raising great expectations among clinicians and researchers. Epigenetic mechanisms regulate gene expression and are sensitive to external stimuli, bridging the gap between environmental and genetic factors. Considerable evidence of epigenetic changes, particularly altered patterns of DNA methylation, exists in diseases such as systemic lupus erythematosus (SLE) and rheumatoid arthritis. The importance of such changes in the pathology of rheumatic diseases has been demonstrated by examining the relationship between gene-specific methylation and SLE in monozygotic twins discordant for the disease, in whom genetic variability is excluded as a cause for discordance. Several studies have highlighted the importance of the tissue-specificity of DNA methylation changes, an aspect which-in contrast with genetic analysis-must be considered when designing epigenetic studies. Here I discuss the proposed mechanisms and implications of DNA methylation changes in the pathogenesis of autoimmune rheumatic diseases, the prospects for future epigenetic studies in rheumatology, the relevance of specific DNA methylation markers and the potential use of drugs with an epigenetic effect in the clinical management of these diseases.
21622765 Repair of bone erosions in rheumatoid arthritis treated with tumour necrosis factor inhibi 2011 Sep OBJECTIVES: To investigate whether bone erosions in patients with rheumatoid arthritis (RA) show evidence of repair. METHODS: 127 erosions were identified in metacarpophalangeal joints 2-4 of the right hands of 30 RA patients treated with tumour necrosis factor inhibitors (TNFi) and 21 sex, age and disease activity-matched patients treated with methotrexate. All erosions were assessed for their exact maximal width and depth by high-resolution µCT imaging at baseline and after 1 year. RESULTS: All erosions detected at baseline could be visualised at follow-up after 1 year. At baseline, the mean width of bone erosions in the TNFi group was 2.0 mm; their mean depth was 2.3 mm, which was not significantly different from the methotrexate-treated group (width 2.4 mm; depth 2.4 mm). Mean depth of erosions significantly decreased after 1 year of treatment with TNFi (-0.1 mm; p=0.016), whereas their width remained unchanged. In contrast, mean depth and width of erosive lesions increased in the methotrexate-treated group. The reduction in the depth of lesions was confined to erosions showing evidence of sclerosis at the base of the lesion. Moreover, deeper lesions in the TNFi group were particularly prone to repair (-0.4 mm; p=0.02) compared with more shallow lesions. CONCLUSIONS: Bone erosions in RA patients treated with TNFi show evidence of limited repair in contrast to bone erosions in patients treated with methotrexate. Repair is associated with a decrease in the depth of lesions and sclerosis at the bases of the lesions. Repair thus emerges from the endosteal rather than periosteal bone compartment and probably involves the bone marrow.
23257762 [Cognitive impairment and anxiety-depressive disorders in patients with rheumatoid arthrit 2012 Data on the prevalence and features of cognitive impairment in patients with rheumatoid arthritis (RA) are presented. Cognitive impairment was noted in 66% of patients, it did not reach the threshold of dementia and met the diagnostic criteria for moderate cognitive impairment. Anxiety-depressive spectrum disorders were found in 94% patients. Cognitive impairment was associated with apathic affect and anxiety-depressive spectrum disorders (depressive episodes, dysthymia, and elevated anxiety). The impairment of thinking was correlated with the high to moderate inflammatory activity including non-joint RA symptoms, higher levels of proinflammatory cytokines and low doses of glucocorticoids. Cognitive impairment was not associated with the duration and character of standard treatment of RA and concomitant cardiovascular diseases.
22147110 Cardiovascular risk in patients with rheumatoid arthritis: assessment of several tradition 2012 Dec The present cross-sectional data demonstrate cardiovascular (CV) risk in patients with rheumatoid arthritis (RA). The cross-sectional data were part of an interventional trial that included 100 patients with defined RA. Traditional CV risk parameters and risk score calculation for the German population were used to assess the CV risk profile in the collective given. Proatherogenic lipid profile characterised by increased total cholesterol (≥ 5.2 mmol/l) and LDL cholesterol (≥ 3.5 mmol/l) levels was measured in 85 and 66%, respectively, of the study population. Elevated concentrations of homocysteine (≥ 10 μmol/l) were reached by 67%. The prevalence of patients at high CV risk was 12% and increased up to 42% after using a multiplication factor of 1.5. No association was seen between the CV risk SCORE and DAS 28 or disease duration. RA patients in this study showed a proatherogenic risk profile with regard to the CV risk factors evaluated. The calculation of a 10-year risk using German risk charts might have led to an overall underestimation of the mean CV risk. Cardiovascular co-morbidity in RA patients must be seen as a major prevention and treatment target and should be monitored adequately.
20810395 MRI in early rheumatoid arthritis: synovitis and bone marrow oedema are independent predic 2011 Mar OBJECTIVES: To determine whether MRI and conventional (clinical and laboratory) measures of inflammation can predict 3-year radiographic changes measured by the van der Heijde Sharp score in patients with early rheumatoid arthritis (RA). METHODS: 55 patients with RA with disease duration <1 year participated in this 3-year follow-up study. Patients were evaluated at baseline, 3, 6, 12 and 36 months by swollen and tender joint count, disease activity score based on 28-joint count, erythrocyte sedimentation rate (ESR), C reactive protein, MRI measures of synovitis, bone marrow oedema and tenosynovitis of the dominant wrist, as well as conventional x-rays of the hands and wrists. RESULTS: All measures of inflammation decreased during the follow-up period. ESR, MRI synovitis and MRI bone marrow oedema were independent predictors of 3-year radiographic progression adjusted for age, sex and anti-citrullinated protein antibodies. The 1-year cumulative measures of MRI synovitis and bone marrow oedema provided an improved explanation of variation (adjusted R(2)) in radiographic change compared with the baseline MRI values (adjusted R(2)=0.32 and 0.20 vs 0.11 and 0.04, respectively). CONCLUSIONS: Both baseline and 1-year cumulative measures of MRI synovitis and bone marrow oedema independently predicted 3-year radiographic progression. These results confirm that MRI synovitis and MRI bone marrow oedema precede radiographic progression in patients with early RA.
