Abstract
OBJECTIVE Rheumatoid arthritis (RA) is associated with an increased risk of cardiovascular disease (CVD), but longitudinal observations are limited and the precise magnitude is unknown. We prospectively assessed the incidence of CVD in patients with RA compared with patients with type 2 diabetes mellitus (DM) and the general population. METHODS The 3-year incidence rate of CVD was determined in a prospective cohort (the Cardiovascular Research and Rheumatoid Arthritis Study) of 353 outpatients with RA, and was compared with that in 1,852 population-based cohort study participants (155 had type 2 DM). We investigated fatal and nonfatal CVD (according to International Classification of Diseases, Ninth Revision criteria) and used Cox proportional hazards models to assess the incidence of CVD in RA, type 2 DM, and the general population. RESULTS The 3-year incidence of CVD was 9.0% in patients with RA and 4.3% in the general population, corresponding with an incidence rate of 3.30 per 100 patient-years (95% confidence interval [95% CI] 2.08-4.25) and 1.51 per 100 person-years (95% CI 1.18-1.84), respectively. Compared with the general population, the age- and sex-adjusted hazard ratio (HR) for RA was 1.94 (95% CI 1.24-3.05, P = 0.004). Neither exclusion of patients with prior CVD at baseline nor adjustment for cardiovascular risk factors significantly influenced this. Compared with the nondiabetic population, nondiabetic patients with RA and those with type 2 DM had comparable HRs, 2.16 (95% CI 1.28-3.63, P = 0.004) and 2.04 (95% CI 1.12-3.67, P = 0.019), respectively. CONCLUSION The risk of CVD in RA was significantly elevated compared with the general population, and comparable with the magnitude of risk in type 2 DM.

Abstract
OBJECTIVES Clinical trials of tumour necrosis factor antagonists have raised questions about the potential risk of certain serious adverse events (SAE). To assess the safety of adalimumab in rheumatoid arthritis (RA) over time and across five other immune-mediated inflammatory diseases and to compare adalimumab malignancy and mortality rates with data on the general population. METHODS This analysis included 19,041 patients exposed to adalimumab in 36 global clinical trials in RA, psoriatic arthritis (PsA), ankylosing spondylitis (AS), Crohn's disease (CD), psoriasis and juvenile idiopathic arthritis (JIA) to 15 April 2007. Events per 100 patient-years were calculated using SAE reported after the first dose to 70 days after the last dose. Standardised incidence rates were calculated for malignancies using national and state-specific databases. Standardised mortality rates (SMR) were calculated for each disease using data from the World Health Organization. RESULTS Cumulative rates of SAE of interest in RA have remained stable over time. Rates of SAE of interest for PsA, AS, CD, psoriasis and JIA were similar to or lower than rates for RA. Overall malignancy rates for adalimumab-treated patients were as expected for the general population. SMR across all six diseases indicated that no more deaths occurred with adalimumab than expected in the general population. CONCLUSIONS Based on 10 years of clinical trial experience across six diseases, this safety report and the established efficacy of adalimumab in these diseases provide the foundation for a better understanding of its benefit-risk profile.

Abstract
OBJECTIVE Preliminary evidence suggests that ankylosing spondylitis (AS) is associated with an increased cardiovascular (CV) risk. We investigated subclinical atherosclerosis and arterial stiffness in patients with AS compared with controls, and identified CV and AS related risk factors for atherosclerotic disease. METHODS A total of 59 patients with AS who were scheduled for etanercept treatment according to the ASsessments in Ankylosing Spondylitis guidelines and 30 healthy controls were recruited. Subclinical atherosclerosis was assessed as the average intima-media thickness (IMT) of the common carotid artery. Arterial stiffness was determined by distensibility, compliance, and Young's elastic modulus of the carotid artery. RESULTS AS patients had a greater IMT (0.62 +/- 0.09 mm vs 0.57 +/- 0.09 mm in controls; p = 0.02), a difference that remained after adjustment for traditional CV risk factors. AS was associated with higher carotid pulse pressure (47 +/- 7 mm Hg vs 44 +/- 8 mm Hg in controls; p = 0.04), but this was not due to local vessel wall properties. Among AS patients, age and body mass index (BMI) were determinants of IMT. Age, BMI, total cholesterol, triglycerides, and disease duration were identified as determinants of stiffness indices. No relationship was found between large-vessel properties and higher Bath AS disease indices or C-reactive protein values. CONCLUSION AS was associated with subclinical atherosclerosis and arterial stiffness, supporting epidemiological evidence of an increased CV risk in these patients. Whether these differences are due to AS or to a higher prevalence of CV risk factors in patients with AS remains to be determined.

Abstract
Several advances have been made in the understanding of the pathogenesis, as well as in the clinical evaluation and treatment, of early inflammatory arthritis. The presence of anti-citrullinated protein antibodies (ACPAs) has emerged as a major new biomarker for use in clinical practice. The presence of ACPAs can be used to divide patients with early arthritis into subsets that are phenotypically similar but have varying pathogenetic and prognostic features. Although the detection of ACPAs is a major development in the diagnosis and prognosis of rheumatoid arthritis (RA), prediction of the outcome of arthritis at the individual level can still be much improved. For patients diagnosed with RA, and who have active polyarthritis, treatment is not dependent on the assessment of prognostic factors, as these patients are best treated with combination therapy; over 40% of these patients achieve remission with such treatment. In patients who present with oligoarthritis, however, management should be based on the assessment of prognostic factors. The success of early treatment of inflammatory arthritis and the recognition of a measurable preclinical phase of RA offer hope that treating the disease before it becomes clinically active might be possible.

Abstract
Objectives:To develop evidence-based EULAR recommendations for cardiovascular (CV) risk management in patients with rheumatoid arthritis (RA), ankylosing spondylitis (AS) and psoriatic arthritis (PsA).Methods:A multidisciplinary expert committee was convened as a task force of the EULAR Standing Committee for Clinical Affairs (ESCCA), comprising 18 members including rheumatologists, cardiologists, internists and epidemiologists, representing nine European countries. Problem areas and related keywords for systematic literature research were identified. A systematic literature research was performed using MedLine, Embase and the Cochrane library through to May 2008. Based on this literature review and in accordance with the EULAR’s “standardised operating procedures”, the multidisciplinary steering committee formulated evidence-based and expert opinion-based recommendations for CV risk screening and management in patients with inflammatory arthritis.Results:Annual CV risk assessment using national guidelines is recommended for all patients with RA and should be considered for all patients with AS and PsA. Any CV risk factors identified should be managed according to local guidelines. If no local guidelines are available, CV risk management should be carried out according to the SCORE function. In addition to appropriate CV risk management, aggressive suppression of the inflammatory process is recommended to further lower the CV risk.Conclusions:Ten recommendations were made for CV risk management in patients with RA, AS and PsA. The strength of the recommendations differed between RA on the one hand, and AS and PsA, on the other, as evidence for an increased CV risk is most compelling for RA.

Abstract
OBJECTIVES Patients with rheumatoid arthritis (RA) have an increased cardiovascular risk, but the magnitude of this risk is not known precisely. A study was undertaken to investigate the associations between RA and type 2 diabetes (DM2), a well-established cardiovascular risk factor, on the one hand, and cardiovascular disease (CVD) on the other. METHODS The prevalence of CVD (coronary, cerebral and peripheral arterial disease) was determined in 353 randomly selected outpatients with RA (diagnosed between 1989 and 2001, aged 50-75 years; the CARRE study) and in participants of a population-based cohort study on diabetes and CVD (the Hoorn study). Patients with RA with normal fasting glucose levels from the CARRE study (RA, n = 294) were compared with individuals from the Hoorn study with normal glucose metabolism (non-diabetic, n = 258) and individuals with DM2 (DM2, n = 194). RESULTS The prevalence of CVD was 5.0% (95% CI 2.3% to 7.7%) in the non-diabetic group, 12.4% (95% CI 7.5% to 17.3%) in the DM2 group and 12.9% (95% CI 8.8% to 17.0%) in those with RA. With non-diabetic individuals as the reference category, the age- and gender-adjusted prevalence odds ratio (OR) for CVD was 2.3 (95% CI 1.1 to 4.7) for individuals with DM2 and 3.1 (95% CI 1.6 to 6.1) for those with RA. There was an attenuation of the prevalences after adjustment for conventional cardiovascular risk factors (OR 2.0 (95% CI 0.9 to 4.5) and 2.7 (95% CI 1.2 to 5.9), respectively). CONCLUSIONS The prevalence of CVD in RA is increased to an extent that is at least comparable to that of DM2. This should have implications for primary cardiovascular prevention strategies in RA.

Abstract
BACKGROUND Adiponectin is an anti-inflammatory and potentially antiatherogenic molecule. Some recent reports suggest that tumour necrosis factor alpha (TNFalpha) blockade therapy increases circulating adiponectin levels, but data are sparse and inconsistent. METHODS Data from a double-blind placebo controlled study of onercept in 126 patients with psoriatic arthritis (PsA) and from pre- and post-adalimumab treatment in 171 patients with rheumatoid arthritis (RA) were used to examine the effect of TNFalpha blockade therapy on adiponectin. RESULTS Despite expected associations of adiponectin with gender and baseline high-density lipoprotein cholesterol and triglyceride, adiponectin levels did not change over time with TNFalpha blockade therapy in either group. The mean+/-SD absolute change in adiponectin levels was -0.23+/-4.6 microg/ml in patients with PsA treated with combined onercept 50 mg and onercept 100 mg (vs placebo, p=0.60) and 0.28+/-3.23 microg/ml in patients with RA treated with adalimumab (vs baseline, p=0.66). CONCLUSION These results do not support a significant effect of TNFalpha blockade therapy on circulating adiponectin levels in patients with autoimmune disease.

Abstract
BACKGROUND In case of contraindications or intolerance during treatment with oral bisphosphonates (OB), administration of pamidronate intravenously is a widely used alternative. In this study we compared the effect on change in bone mineral density (BMD) of the spine and hip during long term treatment with pamidronate iv in comparison to OB. METHODS We studied 61 patients receiving treatment for at least two years. In case of contraindications or intolerance (within 3 months) of an OB, pamidronate iv was started. BMD was measured on a Hologic 4500 and a Lunar DPX-IQ at the spine (L1-L4) and total hip. RESULTS Thirty-one patients were enrolled in the OB group and 30 in the intravenous pamidronate group. Mean follow-up duration (SD) was 4.3 (1.3) years. We observed a significant increase (p < 0.001) in spinal BMD, both in the OB group (8.3%) as well as in the pamidronate iv group (6.1%), but no significant difference in BMD change between the OB and pamidronate iv groups. At the hips, we observed a tendency to increased BMD in both groups, 1.1% in the OB and 1.4% in the pamidronate iv group. CONCLUSION We conclude that intravenous pamidronate is a good alternative for oral bisphosphonates in the treatment of osteoporosis in patients with contraindications or intolerance during treatment with oral bisphosphonates.

Abstract
OBJECTIVES To (i) examine the association between fatigue, psychosocial work characteristics (job control, support, participation in decision making, psychological job demands), and physical work requirements on the one hand and work ability of employees with rheumatoid arthritis (RA) on the other, and (ii) determine the advice that health care professionals give to employees with RA on how to maintain their work ability. METHODS Data were gathered from 78 employees with early RA (response = 99%) by telephone interviews and self-report questionnaires. RESULTS Fatigue, lack of autonomy, low coworker/supervisor support, low participation in decision making, and high physical work requirements (i.e. using manual force) predicted low work ability. High psychological job demands, however, did not predict low work ability. The rheumatologist, occupational physician, occupational therapist, physiotherapist, and psychologist gave advice on how to cope with RA at work to 36, 30, 27, 26, and 17% of the employees, respectively. Advice was directed mainly at factors intrinsic to the employee. Employees expressed a positive attitude towards this advice. CONCLUSIONS Fatigue, lack of support, lack of autonomy, lack of participation in decision making, and using manual force at work (e.g. pushing and pulling) threaten the work ability of employees with RA. According to the employees with RA, involvement of health care professionals from different disciplines and the implementation of organizational and technical interventions would help them to tackle these threats.

Abstract
OBJECTIVE A bioassay is developed for the measurement of methotrexate (MTX) in serum. METHODS The assay is based on MTX inhibition of the proliferation of hypoxanthine-guanosine phosphoribosyl transferase (HGPRT) negative mouse B-cells (B9.H). HGPRT negative cells cannot use the salvage pathway of nucleotide synthesis to overcome inhibition by MTX. RESULTS When B9.H cells are cultured with serial dilutions of serum, inhibition of proliferation is a measure of the amount of MTX in the serum. Circulating folates do not interfere with the assay. CONCLUSION This simple assay can detect low concentrations of MTX in serum: it is therefore useful for following the pharmacodynamics of functional MTX after low-dose MTX treatment.

Abstract
OBJECTIVE To investigate how antibodies against anti-tumour necrosis factor (anti-TNF) agents influence response after switching from infliximab to adalimumab in rheumatoid arthritis (RA). METHODS This cohort study consisted of 235 patients with RA, all treated with adalimumab. At baseline 52 patients (22%) had been previously treated with infliximab ('switchers'), and 183 (78%) were anti-TNF naive. Disease activity (using the 28-joint count Disease Activity Score (DAS28)) and presence of antibodies against infliximab and adalimumab were assessed. Clinical response to adalimumab was compared between switchers and anti-TNF naive patients and their anti-infliximab and anti-adalimumab antibody status. RESULTS After 28 weeks of adalimumab treatment the decrease in DAS28 (Delta DAS28) for the 235 patients was 1.6+/-1.5 (mean+/-SD). Anti-adalimumab antibodies were detected in 46 patients (20%). Delta DAS28 was 1.8+/-1.4 in patients without anti-adalimumab and 0.6+/-1.3 in patients with anti-adalimumab (p<0.0001). Thirty-three of the 52 switchers (63%) had anti-infliximab antibodies. Patients with anti-infliximab more often developed anti-adalimumab than anti-TNF naive patients (11 (33%) vs 32 (18%); p=0.039). Delta DAS28 was greater for anti-TNF naive patients (1.7+/-1.5) than for switchers without anti-infliximab antibodies (Delta DAS28=0.9+/-1.4) (p=0.009). Delta DAS28 for switchers with anti-infliximab was 1.2+/-1.3 and did not differ significantly from anti-TNF naive patients (p=0.262). CONCLUSION Switchers with anti-infliximab antibodies more often develop antibodies against adalimumab than anti-TNF naive patients. Response to adalimumab was limited in switchers without anti-infliximab antibodies, which raises the question whether a second anti-TNF treatment should be offered to patients with RA for whom an initial treatment with an anti-TNF blocker fails, in the absence of anti-biological antibodies.

The clinical manifestations of rheumatoid arthritis (RA) and ankylosing spondylitis (AS) differ in many ways. The age of onset in AS is much younger, with an average onset of 28 years compared with 40-50 years in RA, and with a male predominance (3:1) compared with the female predominance in RA. The genetic association with HLA alleles is stronger in AS, with an HLA-B27 antigen in 95% of the patients compared with RA, with 60% HLA DR4 or DR 1 positives. The type and localisation of arthritis is peripheral polyarthritis in RA, especially with involvement of hands and feet, whereas in AS the arthritis is mainly localized in the spine and sacroiliac joints with an oligoarthritis of the larger joints (hips, knees, shoulders). The radiographic signs in RA show bone resorption with erosive changes in contrast with AS where bone formation with vertebral sydesmophytes is present. Extra-articular manifestations can occur in both diseases but again these manifestations differ in the eye (keratoconjuctivitis sicca and scleritis in RA, versus anterior uveitis in AS), heart (pericarditis in RA, conduction disturbances in AS), lungs (pleural lesions or nodules in RA and fibrosis in AS) and gastrointestinal tract (peptic ulcers in RA and colitis in AS).Both diseases respond well to treatment with NSAIDs but DMARDs, which are very important in RA, have limited value in AS. TNF alfa blocking drugs, however, show a high efficacy in both diseases.

Abstract
OBJECTIVE Cardiovascular mortality is increased in ankylosing spondylitis (AS), and inflammation plays an important role. Inflammation deteriorates the lipid profile and alters high-density lipoprotein cholesterol (HDL-c) composition, reflected by increased concentrations of serum amyloid A (SAA) within the particle. Anti-tumor necrosis factor (anti-TNF) treatment may improve these parameters. We therefore undertook the present study to investigate the effects of etanercept on lipid profile and HDL composition in AS. METHODS In 92 AS patients, lipid levels and their association with the inflammation markers C-reactive protein (CRP), erythrocyte sedimentation rate, and SAA were evaluated serially during 3 months of etanercept treatment. HDL composition and its relationship to inflammation markers was determined in a subgroup of patients, using surface-enhanced laser desorption/ionization time-of-flight analysis. RESULTS With anti-TNF treatment, levels of all parameters of inflammation decreased significantly, whereas total cholesterol, HDL-c, and apolipoprotein A-I (Apo A-I) levels increased significantly. This resulted in a better total cholesterol:HDL-c ratio (from 3.9 to 3.7) (although the difference was not statistically significant), and an improved Apo B:Apo A-I ratio, which decreased by 7.5% over time (P=0.008). In general, increases in levels of all lipid parameters were associated with reductions in inflammatory activity. In addition, SAA was present at high levels within HDL particles from AS patients with increased CRP levels and disappeared during treatment, in parallel with declining plasma levels of SAA. CONCLUSION Our results show for the first time that during anti-TNF therapy for AS, along with favorable changes in the lipid profile, HDL composition is actually altered whereby SAA disappears from the HDL particle, increasing its atheroprotective ability. These findings demonstrate the importance of understanding the role of functional characteristics of HDL-c in cardiovascular diseases related to chronic inflammatory conditions.

Abstract
ObjectiveIncreased expression of insulin-like growth factor 2 (IGF2) by fibroblast-like synoviocytes (FLS) was associated with low inflammatory synovium of patients with rheumatoid arthritis (RA). The aim of this study was to analyse whether the differential expression of IGF2, whose expression is normally restricted to one allele, is due to activation of the normally suppressed allele.MethodsIGF2 gene expression of RA FLS was quantified by quantitative real-time PCR. FLS heterozygous for a 3′-untranslated region IGF2 polymorphism were selected to measure the relative contribution of the allelic transcripts by allele-specific transcript quantification assay. Proliferation was determined by [3H]thymidine incorporation.ResultsIGF2 was shown to contribute to RA FLS proliferation. FLS could be classified in IGF2 high and IGF2 low-expressing cell lines. Allelic IGF2 transcript quantification analysis revealed that in part of the RA FLS the normally suppressed allele was activated, resulting in biallelic expression of the IGF2 gene. Biallelic expression was associated with increased levels of IGF2 mRNA production.ConclusionThe findings indicate that the imprinting status of IGF2 might underlie the increased expression of IGF2, which may contribute to autonomous growth of RA FLS of low inflammatory synovial tissues.

Abstract
Introduction The aim of this study was to examine seroconversion and the relationship with age and inflammation of autoantibodies in a large group of patients attending an outpatient rheumatology clinic. Methods Levels of antibodies to citrullinated proteins/peptides (ACPAs) and IgM rheumatoid factor (IgM-RF) were determined in 22,427 samples collected from 18,658 patients. The diagnosis was derived from a diagnosis registration system. The degree of seroconversion in repeated samples and the correlation of levels with age and inflammatory markers were determined for ACPA and IgM-RF in rheumatoid arthritis (RA) and non-RA patients. Results Seventy-one percent of RA patients (n = 1,524) were ACPA-positive and 53% were IgM-RF-positive; in non-RA patients (n = 2,245), the corresponding values were 2% and 4%, respectively. In patients with at least two samples (n = 3,769), ACPA status was more stable than IgM-RF status in RA patients. ACPA- or IgM-RF-negative non-RA patients seldom became positive. ACPA positivity was unrelated to age in both RA and non-RA patients. IgM-RF positivity was unrelated to age in RA patients; however, it increased with age in non-RA patients. The correlation between autoantibody levels and inflammatory markers was low in general and was somewhat higher for IgM-RF than for ACPA. Conclusions ACPA status is more stable in time and with increasing age than IgM-RF status, further establishing its role as a disease-specific marker. ACPA and IgM-RF levels are only moderately correlated with markers of inflammation.
