Abstract
OBJECTIVE To investigate real-world retention and remission rates in PsA patients initiating a 2nd or 3rd TNFi and the association with reason for discontinuation from the previous TNFi-treatment. METHODS Prospectively collected routine care data from 12 European registries were pooled. Retention rates (Kaplan-Meier estimation) and crude/LUNDEX-adjusted rates of Disease Activity Score 28 and Disease Activity index for PSoriatic Arthritis (DAS28 and DAPSA28) remission were calculated and compared with adjusted Cox regression analyses and Chi-squared test, respectively). RESULTS We included 5233 (2nd TNFi) and 1906 (3rd TNFi) patients. Twelve-month retention rates for the 2nd and 3rd TNFi were 68% (95%CI: 67-70%) and 66% (64-68%), respectively. Patients who stopped the previous TNFi due to AE/LOE had 12-month retention rates of 66%/65% (2nd TNFi), and 65%/63% (3rd TNFi), respectively. Patients who stopped the previous TNFi due to LOE after less vs more than 24 weeks had 12-month retention rates of 54%/69% (2nd TNFi), and 58%/65% (3rd TNFi). Six-month crude/LUNDEX-adjusted DAS28 remission rates were 48%/35% and 38%/27%, and DAPSA28 remission rates were 19%/14% and 14%/10%, for the 2nd and 3rd TNFi. CONCLUSION Two-thirds of patients remained on TNFi at 12months for both the 2nd and 3rd TNFi, while one-third and one-quarter of patients were in DAS28 remission after 6months on the 2nd and 3rd TNFi. While drug effectiveness was similar in patients who stopped the previous TNFi due to AE compared to overall LOE, drug effectiveness was better in patients who had stopped the previous TNF due to secondary LOE compared to primary LOE.

Abstract
OBJECTIVE To study the long-term effect of 16 weeks of etanercept treatment on disease activity and radiographic changes in patients with suspected non-radiographic axial spondyloarthritis (nr-axSpA). METHOD Eighty patients with inflammatory back pain and suspected nr-axSpA, with a Bath Ankylosing Disease Activity Index (BASDAI) ≥ 4, received etanercept (n = 40) 25 mg twice weekly or placebo (n = 40) for 16 weeks. They were followed without treatment restrictions after 24 weeks, for up to 3 years. Comparisons were made between patients who received etanercept or placebo in the first period, and changes in BASDAI, Ankylosing Spondylitis Disease Activity Score (ASDAS), Bath Ankylosing Spondylitis Metrology Index (BASMI), function, and radiographic changes in the spine [according to the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS)] and sacroiliac joints (Bath Ankylosing Spondylitis Radiology Index (BASRI). RESULTS After 3 years of follow-up, 84% of the patients were diagnosed with SpA, predominantly axSpA. Biological treatment was started after 24 weeks in 30% of patients. Disease activity scores after 3 years did not reveal significant differences between the initial randomization groups in mean BASDAI scores (mean difference 0.9, 95% CI -1.1;0.7, p = 0.6) and ASDAS (mean ASDAS 0.3, 95% CI 0.6;3.1, p = 0.5). BASMI and function scores remained stable over 3 years. No differences in radiographic changes of the sacroiliac joints or spine were observed over 3 years between the two groups. CONCLUSION A short course of etanercept in patients with suspected nr-axSpA did not affect disease activity, the chance of biological treatment, or radiographic progression after 3 years of follow-up.

Abstract
BACKGROUND Biologicals, such as anti-tumor necrosis factor (anti-TNF), reduce cardiovascular disease (CVD) in patients with inflammatory rheumatic diseases. Impaired renal function is a known predictor of CVD and elevated in ankylosing spondylitis (AS). OBJECTIVE To assess the effect of anti-TNF on renal function in patients with AS and whether anti-TNF use is safe in AS patients with pre-existing risk factors for renal decline. METHOD Biological-naïve consecutive AS patients treated with etanercept or adalimumab were prospectively followed from 2005 to 2014. Renal function was determined by calculation of the estimated glomerular filtration rate (eGFR), estimated with the abbreviated modification of diet in renal disease (MDRD) formula. The effect of anti-TNF on eGFR was analyzed using mixed model analysis. RESULTS 211 AS patients were followed for a median of 156 (36-286) weeks. Overall mixed model analyses showed a significant decrease of eGFR over time (β = - 0.040, p = 0.000), although this association did not remain significant after adjustment for responding to anti-TNF, alcohol use, disease duration, body mass index (BMI), C-reactive protein (CRP), and disease activity (β = - 0.018, p = 0.094). However, patients with pre-existing risk factors for renal decline did have a significant change in eGFR over time (β = - 0.029, p = 0.006). CONCLUSIONS We found a significant change in eGFR over time, although this small decrease was not clinically relevant. This study further demonstrates that anti-TNF does not affect renal function in AS patients with and without existing risk factors for renal decline, which means that use of anti-TNF is safe concerning renal function in patients with AS. Key Points • Previous studies showed that biologicals, such as anti-tumor necrosis factor (anti-TNF), reduce cardiovascular disease (CVD) in patients with inflammatory rheumatic diseases, such as ankylosing spondylitis (AS). • Impaired renal function is a known predictor of CVD, and also a known concern for many AS patients. • Use of anti-TNF is safe with regard to renal function in patients with AS. • The effect of anti-TNF on CVD in AS patients does not seem to be mediated by changes in renal function.

Abstract
OBJECTIVE To assess sex differences in response, level of disease activity, and drug survival in tumour necrosis factor inhibitor (TNFi)-naïve ankylosing spondylitis (AS) patients. METHOD Consecutive AS patients, fulfilling the modified New York criteria, were included in a prospective cohort study at initiation of the first TNFi and followed until this medication was stopped (drug survival). Disease activity scores [AS Disease Activity Score using C-reactive protein (ASDAS-CRP), Bath AS Disease Activity Index (BASDAI), and CRP] were measured at 3, 6, and 12 months, and every subsequent year, up to 5 years. The response was defined by the ASDAS-CRP response criteria (clinically important improvement: ASDAS-CRP decrease ≥ 1.1). Analyses included regression methods for repeated measurements and survival analyses. RESULTS Overall, 356 patients were included (34% women, mean ± sd age 46 ± 12 years), with a median disease duration of 12 (interquartile range 6;20) years. Women were less likely than men to achieve a clinically important response after 6 months of TNFi treatment (47% vs 64%; relative risk 1.4, 95% confidence interval (CI) 1.1;1.9, p = 0.02], despite a lack of sex differences in mean ASDAS-CRP levels over 5 year follow-up. Adjusted models for BASDAI over 5 years showed that women had a 0.6 point higher BASDAI score than men (β = 0.6 0.1;1.1 <0.02). Numerically, more women than men discontinued treatment over a period of 5 years (hazard ratio = 1.5, 95% CI 0.9;2.5, p = 0.15). CONCLUSION Female AS patients show a lower response to TNFi and a higher disease activity compared to men.

Abstract
OBJECTIVES To assess the impact of 'patient's minus evaluator's global assessment of disease activity' (ΔPEG) at treatment initiation on retention and remission rates of TNF inhibitors (TNFi) in psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA) patients across Europe. METHODS Real-life data from PsA and axSpA patients starting their first TNFi from 11 countries in the European Spondyloarthritis Research Collaboration Network were pooled. Retention rates were compared by Kaplan-Meier analyses with log-rank test and by Cox regression, and remission rates by χ2 test and by logistic regression across quartiles of baseline ΔPEG, separately in female and male PsA and axSpA patients. RESULTS We included 14 868 spondyloarthritis (5855 PsA, 9013 axSpA) patients. Baseline ΔPEG was negatively associated with 6/12/24-months' TNFi retention rates in female and male PsA and axSpA patients (P <0.001), with 6/12/24-months' BASDAI < 2 (P ≤0.002) and ASDAS < 1.3 (P ≤0.005) in axSpA patients, and with DAS28CRP(4)<2.6 (P ≤0.04) and DAPSA28 ≤ 4 (P ≤0.01), but not DAS28CRP(3)<2.6 (P ≥0.13) in PsA patients, with few exceptions on remission rates. Retention and remission rates were overall lower in female than male patients. CONCLUSION High baseline patient's compared with evaluator's global assessment was associated with lower 6/12/24-months' remission as well as retention rates of first TNFi in both PsA and axSpA patients. These results highlight the importance of discordance between patient's and evaluator's perspective on disease outcomes.

Abstract
Given the link between systemic inflammation, body composition and insulin resistance (IR), anti-inflammatory therapy may improve IR and body composition in inflammatory joint diseases. This study assesses the IR and beta cell function in rheumatoid arthritis (RA) patients with active disease compared to osteoarthritis (OA) patients and investigates the effect of anti-TNF treatment on IR, beta cell function and body composition in RA. 28 Consecutive RA patients starting anti-TNF treatment (adalimumab), and 28 age, and sex-matched patients with OA were followed for 6 months. Exclusion criteria were use of statins, corticosteroids, and cardiovascular or endocrine co-morbidity. Pancreatic beta cell function and IR, using the homeostasis model assessment (HOMA2), and body composition, using dual-energy X-ray absorptiometry (DXA) were measured at baseline and 6 months. At baseline, IR [1.5 (1.1–1.8) vs. 0.7 (0.6–0.9), 100/%S] and beta cell function (133% vs. 102%) were significantly (p < 0.05) higher in RA patients with active disease as compared to OA patients. After 6 months of anti-TNF treatment, IR [1.5 (1.1–1.8) to 1.4 (1.1–1.7), p = 0.17] slightly improved and beta cell function [133% (115–151) to 118% (109–130), p <0.05] significantly improved. Improvement in IR and beta cell function was most pronounced in RA patients with highest decrease in CRP and ESR. Our observations indicate that IR and increased beta cell function are more common in RA patients with active disease. Anti-TNF reduced IR and beta cell function especially in RA patients with highest decrease in systemic inflammation and this effect was not explained by changes in body composition.

Abstract
Abstract
Objective
To investigate TNF inhibitor (TNFi) retention and response rates in European biologic-naïve patients with PsA.
Methods
Prospectively collected data on PsA patients in routine care from 12 European registries were pooled. Heterogeneity in baseline characteristics between registries were explored (analysis of variance and pairwise comparison). Retention rates (Kaplan–Meier), clinical remission [28-joint count DAS (DAS28) <2.6; 28 joint Disease Activity index for Psoriatic Arthritis ⩽4] and ACR criteria for 20% improvement (ACR20)/ACR50/ACR70 were calculated, including LUNDEX adjustment.
Results
Overall, 14 261 patients with PsA initiated a first TNFi. Considerable heterogeneity of baseline characteristics between registries was observed. The median 12-month retention rate (95% CI) was 77% (76, 78%), ranging from 68 to 90% across registries. Overall, DAS28/28 joint Disease Activity index for Psoriatic Arthritis remission rates at 6 months were 56%/27% (LUNDEX: 45%/22%). Six-month ACR20/50/70 responses were 53%/38%/22%, respectively. In patients initiating a first TNFi after 2009 with registered fulfilment of ClASsification for Psoriatic ARthritis (CASPAR) criteria (n = 1980) or registered one or more swollen joint at baseline (n = 5803), the retention rates and response rates were similar to those found overall.
Conclusion
Approximately half of >14 000 patients with PsA who initiated first TNFi treatment in routine care were in DAS28 remission after 6 months, and three-quarters were still on the drug after 1 year. Considerable heterogeneity in baseline characteristics and outcomes across registries was observed. The feasibility of creating a large European database of PsA patients treated in routine care was demonstrated, offering unique opportunities for research with real-world data.

Abstract
Background Diastolic left ventricular (LV) dysfunction appears more prevalent in ankylosing spondylitis (AS). The effects of tumor necrosis factor alpha (TNF-α) blocking therapy, a strong and effective anti-inflammatory drug, on diastolic LV function in AS are unknown. The objective of the study was to find the effects of 1-year treatment with golimumab 50 mg subcutaneously once per month on systolic and diastolic LV dysfunction in AS patients. Methods Forty consecutive AS patients were treated with TNF-α blocking therapy for 1 year. Transthoracic echocardiography was performed in all patients at baseline and after 1 year of treatment. Results Diastolic LV function improved after treatment in four out of six (67%) AS patients who completed follow-up (P=0.125), and did not develop or worsen in any of the other patients. Treatment with TNF-α blocking therapy had no effect on systolic LV function. Conclusion These findings give support to the hypothesis that diastolic LV dysfunction improves during treatment with TNF-α blocking therapy.

Abstract
PURPOSE OF REVIEW Ankylosing spondylitis (AS) was historically seen as a predominantly male disease. However, more recent data showed a more homogenous sex prevalence. Unfortunately, in many studies in axial spondyloarthritis (axSpA), the number of women included is low and the analyses are often not stratified for gender distribution. The purpose of this review is to aggregate the existing data on gender differences in axSpA in order to increase the awareness that female axSpA patients are still under-recognized. RECENT FINDINGS Several studies considering gender differences revealed that female axSpA patients had different disease manifestations due to different immunological, hormonal, and genetic responses. For instance, allelic frequencies of the AHNK-gene and tissue non-specific alkaline phosphatase (TNAP) haplotypes differed between men and women with ankylosing spondylitis (AS). In addition, different levels of tumor necrosis factor (TNF), interleukins IL-6, IL-17, and IL-18, were found between the two sexes. Furthermore, female patients show a higher diagnostic delay compared to males. Several studies indicate a higher frequency of extra-articular manifestations (EAM) in female axSpA patients, such as enthesitis, psoriasis, and inflammatory bowel disease (IBD), whereas acute anterior uveitis is more prevalent in male patients. Male AS patients more frequently show a higher Bath Ankylosing Spondylitis Radiology Index (BASRI) scores and modified Stoke Ankylosing Spondylitis Spine Scores (mSASSS) than females, which indicates that males have higher radiological damage and radiographic progression. However, disease activity (BASDAI) and quality of life (AsQol) scores are significantly higher in women, and more importantly, they have significantly lower response rates to treatment with TNF inhibitors (TNFi) and a significantly lower drug adherence. Despite the fact that men with axial SpA have a worse radiologic prognosis, women have a high disease burden, in part because they have a longer delay in diagnosis, higher disease activity, and significantly less responsiveness to treatment with TNFi.

Abstract
OBJECTIVE To compare rates of drug survival and clinical response during 2 years of follow-up in ankylosing spondylitis (AS) patients treated with etanercept or adalimumab in routine care. METHOD Biological-naïve consecutive AS patients treated with etanercept (n = 163) or adalimumab (n = 82) were followed. Treatment discontinuation was due to inefficacy, adverse events, loss to follow-up, planning a pregnancy, or uveitis. Disease activity was assessed by the Ankylosing Spondylitis Disease Activity Score using C-reactive protein (ASDAS-CRP). Moderate disease activity was defined as an ASDAS-CRP < 2.1. RESULTS Twenty-seven patients (32.9%) treated with adalimumab and 30 (18.4%) with etanercept discontinued treatment. Cox regression analysis demonstrated a significant difference in survival rate between discontinuation of the drug in adalimumab patients compared with etanercept patients [hazard ratio (HR) 2.1, 95% confidence interval (CI) 1.3-4.5, p = 0.005; corrected for confounding factors: HR 2.5, 95% CI 1.3-4.5, p = 0.006]. There was no significant difference at 2 years of follow-up between the adalimumab- and the etanercept-treated patients in mean ± sd ASDAS-CRP (1.9 ± 1.1 and 2.0 ± 0.9, respectively, p = 0.624), and 23 out of 34 (67.6%) compared to 71 out of 117 (60.7%) reached ASDAS-CRP moderate disease activity (odds ratio 0.738, 95% CI 0.329-1.657, p = 0.530). CONCLUSION No significant difference was found between AS patients treated with etanercept and those treated with adalimumab in mean ASDAS-CRP and reaching ASDAS-CRP minimal disease activity at 2 year follow-up. Drug survival rate was higher in etanercept- compared to adalimumab-treated patients. However, this should be interpreted cautiously as the risk of allocation bias cannot be excluded.

Abstract
Objective To analyse the treatment outcome of patients with ankylosing spondylitis (AS) in the European AS infliximab cohort (EASIC) study after a total period of 8 years with specific focus on dosage and the duration of intervals between infliximab infusions. Methods EASIC included patients with AS who had received infliximab for 2 years as part of the ASSERT trial. After that period, rheumatologists were free to change the dose or the intervals of infliximab. Clinical data were status at baseline, end of ASSERT and for a total of 8 years of follow-up. Results Of the initially 71 patients with AS from EASIC, 55 patients (77.5%) had completed the 8th year of anti-tumour necrosis factor (TNF) treatment. Of those, 48 patients (87.3%) still continued on infliximab. The mean infusion interval increased slightly from 6 to 7.1±1.5 weeks, while 45.8% patients had increased the intervals up to a maximum of 12 weeks. The mean infliximab dose remained stable over time, with a minimum of 3.1 mg/kg and a maximum of 6.4 mg/kg. In patients receiving <5 mg/kg infliximab, the mean infusion interval increased to 7.0±1.2 weeks. In total, the mean cumulative dose per patient and per year decreased from 3566.30 to 2973.60 mg. Conclusions We could observe that over a follow-up of 8 years of treatment with infliximab, >85% patients still remained on the same treatment, without any major safety events. Furthermore, both the infusion intervals and also the mean infliximab dose were modestly reduced in ≥70% of the patients without the loss of clinical efficiency.

Abstract
BACKGROUND Previous data have shown that etanercept levels are associated with clinical response in rheumatoid arthritis. However, for ankylosing spondylitis (AS), data regarding this topic are inconclusive. OBJECTIVES To investigate the relationship between etanercept levels and clinical response in patients with AS. METHODS Observational prospective cohort study of 162 patients with AS =treated with etanercept, monitored during 24 weeks of treatment. Etanercept trough levels were determined, retrospectively, using an ELISA. Disease activity was measured using AS Disease Activity Score (ASDAS), including C-reactive protein (CRP) and Bath AS Disease Activity index (BASDAI). Active disease was defined as ASDAS≥2.1. Since etanercept is a drug administered at home there might have been some variation in trough level sampling. RESULTS At 24 weeks etanercept levels were significantly higher in patients with ASDAS<2.1, (3.8 mg/L; IQR 2.5-5.2) compared with patients with ASDAS≥2.1 (2.3 mg/L; IQR 1.2-3.4; p≤0.001). Generalised estimating equation analysis demonstrated a statistically significant association between etanercept levels and ASDAS, BASDAI, CRP and erythrocyte sedimentation rate (all p<0.001). When patients were categorised into quartiles according to etanercept levels, the lowest quartile (etanercept<1.80 mg/L) comprised 35% of all patients with ASDAS≥2.1 while the highest quartile comprised only 14%. CONCLUSIONS Disease activity and inflammation are associated with etanercept levels in patients with AS at 24 weeks of treatment. Measuring etanercept levels might help in identifying overtreatment and undertreatment and optimise etanercept therapy in AS.

Abstract
TNF-alpha blocking agents are very effective in patients with ankylosing spondylitis (AS), but several cases of liver problems have been published. We systematically studied the frequency of this potential side effect in our AS patients treated with etanercept. Consecutive AS patients treated with etanercept for at least 3 months were included. Liver disease was defined as elevated liver enzymes more than 1.5 times the upper normal limit (UNL) and was categorised as probably, possibly, probably not or not related to etanercept treatment. Patients with and without raised liver enzymes were compared for prognostic factors. A total of 105 patients were included. Fifteen patients had elevated liver enzymes more than once. In nine cases, the liver disease was probably (five) or possibly (four) related to etanercept treatment. The liver enzyme elevations were serious (>3× UNL) in six cases and resulted in permanent cessation of etanercept in two cases. The nine patients with liver disease were compared with patients without elevated liver enzymes. No differences were found in age or use of alcohol; however, in patients with liver disease, a higher body mass index and a trend for a higher atherogenic index were observed. Hepatic steatosis was observed in five of six patients with elevated liver enzymes. Elevated serum aminotransferases, probably or possibly related to etanercept treatment, were observed in 9 % of the AS patients. An increased risk for the elevation of liver enzymes was found in patients with a higher body mass index. We recommend regular testing of liver enzymes in patients treated with etanercept.

Abstract
UNLABELLED We demonstrated that vertebral fractures (VF) are commonly found in early SpA. Patients with VF had lower lumbar BMD than patients without VF. VF remained frequently 'unrecognized' and untreated. VF have been associated with more back pain, reduced Qol, and increased risk of future fractures which stresses the importance of recognition also in early stage SpA. INTRODUCTION VF are a common complication of long-standing ankylosing spondylitis (AS). However, data of VF in early AS patients and in other spondylarthropathies (SpA) are scarce. Therefore we examined the prevalence of VF in early SpA patients and investigated the associations between VF and demographic and disease-related variables. METHODS SpA patients were included consecutively and radiographs of the spine were made. VF were assessed according to the method of Genant et al.: fractures were defined as reduction of ≥20% of the vertebrae. Descriptive statistics, t-tests and logistic regression analyses were used to study the relationship between VF and demographic and disease-related variables, radiographic damage and BMD. RESULTS A total of 113 early SpA patients were included with a disease duration of 7 months, a mean age of 37 years. Seventeen patients (15%) had at least one VF. Fourteen patients had one VF, three patients had two VF. Most VF were located at Th6-Th8. In patients with VF, bone mineral density (BMD) of lumbar spine was lower than BMD of patients without VF (t-test: p = 0.043). Axial Psoriatic Arthritis (PsA) was significantly associated with a higher risk for VF (odds ratio [OR]: 4.62, 95% confidence interval [CI] 1.15-18.58, p = 0.031). No significant associations were found with disease activity variables nor with radiographic severity. CONCLUSION In a group of 113 early, young SpA patients, 15% already had at least one VF. Most VF were asymptomatic, undetected by routine diagnostic procedures and located at the mid-thoracic spine. The VF were associated with low BMD of the lumbar spine and with axial PsA.

Abstract
OBJECTIVES To study the long-term efficacy and safety of treatment with infliximab in patients with ankylosing spondylitis (AS) in a real life setting. METHODS AS patients from 6 European countries who had finished the 2-year trial ASSERT were invited to participate in the open- label investigator-driven study EASIC. At baseline, 2 groups were formed: patients of group 1 had not been treated with infliximab after ASSERT, while those of group 2 had continuously received it. Patients of group 1 were further subdivided in group 1a: patients with a relapse and 1b: in remission. All patients of group 1a and 2 continuously received infliximab for 96 weeks, mean dose 5 mg/kg, intervals 6-8 weeks. Patients of group 1b were also treated in case of relapse. RESULTS A total of 103/149 patients (69%) were included in EASIC, 1.3 ± 0.9 years after the end of ASSERT: 9 in group 1a, 5 in group 1b and 89 in group 2. Most patients were male (83%), mean age 44 years. Most patients of group 2 completed the trial (86%) vs. only 5 of group 1 (33%) - mostly due to allergic reactions after readministration of infliximab. In total, there were 22 drop-outs due to 6 adverse events, 4 lack of efficacy, 3 planned pregnancy. All standard assessments indicated beneficial values over time, at week 96 significantly better than at baseline of ASSERT. CONCLUSIONS The majority of patients were continuously and successfully treated with infliximab for 5 years, whereas discontinuation and reintroduction of therapy was less satisfactory due to the frequent occurrence of hypersensitivity reactions. Anti-TNF therapy with infliximab proved to be effective and safe on a long-term basis.

Abstract
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
ObjectiveTo ascertain the prevalence of myocardial infarction (MI) in ankylosing spondylitis (AS) relative to that in the general population.MethodsA questionnaire was sent to 593 patients with AS, aged between 50 and 75 years and registered at the Jan van Breemen Institute or VU University Medical Centre. A total of 383 (65%) patients with AS returned their questionnaire that covered the primary outcome, (non-fatal) MI. The prevalence of MI was calculated with data from the general population provided by Netherlands Information Network of General Practice databases as reference.ResultsThe overall prevalence for MI was 4.4% in patients with AS versus 1.2% in the general population, resulting in an age- and gender-adjusted odds ratio of 3.1 (95% CI 1.9 to 5.1) for patients with AS. When non-responders (35%) were considered as non-MI the odds ratio decreased to 1.9 (95% CI 1.2 to 3.2).ConclusionsThese observations indicate that the prevalence of MI is increased in patients with AS.

Abstract
BACKGROUND Anti-citrullinated protein antibodies (ACPA) are associated with increased risk for rheumatoid arthritis. OBJECTIVE To investigate the effect of the presence and levels of ACPA on arthritis development in patients with arthralgia. METHODS Patients with arthralgia positive for ACPA or IgM rheumatoid factor (IgM-RF) were tested for the shared epitope (SE) and were prospectively followed up for at least 12 months. Absence of clinical arthritis at inclusion and arthritis development during follow-up were independently confirmed by two investigators. Cox regression hazard analyses were used to calculate hazard ratios (HRs) for arthritis development. RESULTS 147 patients with arthralgia were included (50 ACPA positive, 52 IgM-RF positive and 45 positive for both antibodies). After a median follow-up of 28 months (interquartile range (IQR) 19-39), 29 patients developed arthritis in a median of 4 (IQR 3-6) joints and 26 (90%) of these were ACPA positive. The presence of ACPA (HR = 6.0; 95% confidence interval (95% CI) 1.8 to 19.8; p = 0.004), but not of IgM-RF (HR = 1.4, 95% CI 0.6 to 3.1) nor the SE (HR = 1.5, 95% CI 0.7 to 3.0), was associated with arthritis development. Within the group of ACPA-positive patients, the risk for arthritis was enhanced by the presence of IgM-RF (HR = 3.0; 95% CI 1.4 to 6.9; p = 0.01) and high ACPA levels (HR = 1.7; 95% CI 1.1 to 2.5; p = 0.008), but not the SE (HR = 1.0; 95% CI 0.5 to 2.1; p = 1.0). CONCLUSION In patients with arthralgia the presence of ACPA (but not of IgM-RF or SE) predicts arthritis development. The risk in ACPA-positive patients may be further increased by the concomitant presence of IgM-RF or high levels of ACPA.

Abstract
OBJECTIVE Non-radiographic axial spondyloarthritis (SpA) is characterised by a lack of definitive radiographic sacroiliitis and is considered an early stage of ankylosing spondylitis. The objective of this study was to develop candidate classification criteria for axial SpA that include patients with but also without radiographic sacroiliitis. METHODS Seventy-one patients with possible axial SpA, most of whom were lacking definite radiographic sacroiliitis, were reviewed as "paper patients" by 20 experts from the Assessment of SpondyloArthritis international Society (ASAS). Unequivocally classifiable patients were identified based on the aggregate expert opinion in conjunction with the expert-reported level of certainty of their judgement. Draft criteria for axial SpA were formulated and tested using classifiable patients. RESULTS Active sacroiliitis on magnetic resonance imaging (MRI) (odds ratio 45, 95% CI 5.3 to 383; p<0.001) was strongly associated with the classification of axial SpA. The knowledge of MRI findings led to a change in the classification of 21.1% of patients. According to the first set of candidate criteria (sensitivity 97.1%; specificity 94.7%) a patient with chronic back pain is classified as axial SpA in the presence of sacroiliitis by MRI or x rays in conjunction with one SpA feature or, if sacroilitiis is absent, in the presence of at least three SpA features. In a second set of candidate criteria, inflammatory back pain is obligatory in the clinical arm (sensitivity 86.1%; specificity 94.7%). CONCLUSION The ASAS group has developed candidate criteria for the classification of axial SpA that include patients without radiographic sacroiliitis. The candidate criteria need to be validated in an independent international study.

Abstract
Objectives:Ankylosing spondylitis (AS) is associated with increased cardiovascular morbidity and mortality. Microvascular function has been linked to several risk factors for cardiovascular disease. Inflammation in AS may cause microvascular dysfunction. To test this, we assessed microvascular function in (a) patients with AS compared to healthy controls and (b) patients with AS before and after 1 month of anti-tumour necrosis factor (TNF)α treatment with etanercept.Methods:A total of 15 consecutive patients with AS, who were scheduled for etanercept treatment according to the Assessment in Ankylosing Spondylitis (ASAS) group guidelines, and 12 healthy controls matched for age and sex, were recruited. Endothelium-dependent and independent vasodilatation in skin were evaluated with laser Doppler fluxmetry after iontophoresis of acetylcholine and sodium nitroprusside, respectively. Videomicroscopy was used to measure recruitment of skin capillaries after arterial occlusion.Results:Compared to healthy controls, patients with AS had impaired endothelium-dependent vasodilatation and capillary recruitment. Following anti-TNFα treatment, microvascular function improved significantly for endothelium-dependent vasodilatation (p = 0.03) and capillary recruitment (p = 0.006). A significant correlation was observed between changes in endothelium-dependent vasodilatation and changes in erythrocyte sedimentation rate (ESR) (r = −0.56; p = 0.03).Conclusion:Microvascular dysfunction is present in patients with AS with active disease, but improves as inflammation regresses after TNFα blockade.

Abstract
OBJECTIVES Patients presenting with both arthralgia and antibodies to cyclic citrullinated peptide (anti-CCP) have an increased risk of developing rheumatoid arthritis (RA). To further characterise this patient group and shed more light on its relationship with clinically manifest early arthritis and established RA, an immunogenetic and serological analysis was performed. METHODS In a group of 111 patients with anti-CCP-positive arthralgia, anti-CCP levels and shared epitope (SE) status were determined. Data were compared with 125 and 128 patients with anti-CCP-positive early arthritis and established RA respectively. RESULTS In patients with anti-CCP-positive arthralgia, the frequency of SE allele positivity is significantly lower when compared with anti-CCP-positive early arthritis and established RA (58% vs 80%, and 58% vs 92%, respectively, both p<0.001). Median anti-CCP levels were higher in the group of patients with SE-positive arthralgia compared with the group of patients with SE-negative arthralgia (p = 0.02). Median anti-CCP levels were similar in the groups of patients with SE-positive arthralgia and arthritis. CONCLUSIONS The lower frequency of SE positivity in patients with arthralgia compared with patients with RA indicates that, compared with patients who were SE positive, patients who were SE negative as a group go through a longer arthralgia phase, or alternatively have a lower risk for transition from anti-CCP positive arthralgia to RA. Furthermore, the present results suggest that in this early stage the effect of the SE on disease risk may be mediated through higher anti-CCP levels.

Abstract
BACKGROUND Immunogenicity, specifically the onset of antibodies against tumour necrosis factor (TNF) blocking agents, seems to play an important role in non-response to treatment with these drugs. OBJECTIVES To assess the relation of clinical response of ankylosing spondylitis (AS) to etanercept with etanercept levels, and the presence of antibodies to etanercept. METHODS Patients with AS were treated with etanercept 25 mg twice weekly, according to the international Assessment in Ankylosing Spondylitis (ASAS) working group consensus statement. Sera were collected at baseline and after 3 and 6 months of treatment. Clinical response was defined as a 50% improvement or as an absolute improvement of 2 points on a (0-10 scale) Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score. Functional etanercept levels were measured by a newly developed ELISA, measuring the binding of etanercept to TNF. Antibodies against etanercept were measured with a two-site assay and antigen binding test. Clinical data were used to correlate disease activity with serum etanercept levels. RESULTS In all, 53 consecutive patients were included. After 3 months of treatment 40 patients (76%) fulfilled the response criteria. Mean etanercept levels were 2.7 mg/litre and 3.0 mg/litre after 3 and 6 months respectively. Characteristics and etanercept levels of responders and non-responders were similar. No antibodies to etanercept were detected with any of the assays. CONCLUSION Etanercept levels of responders and non-responders were similar and no antibodies to etanercept were detected with any of the assays. This study indicates that etanercept is much less immunogenic compared with the other TNF-blocking agents.

Abstract
Cardiovascular disease is the leading cause of death in patients with rheumatoid arthritis (RA), ankylosing spondylitis (AS) and systemic lupus erythematosus (SLE). In addition to mortality, cardiovascular morbidity is also markedly increased in these patients, compared with the general population. The increased cardiovascular risk can be explained only partially by an increased prevalence of classical risk factors for cardiovascular disease; it also appears to be related to inflammation. Prospective intervention trials aimed at the modification of cardiovascular risk factors are needed to determine the impact of cardiovascular risk reduction in patients with rheumatic disease. In addition to SLE, RA and AS should be acknowledged as new risk factors for cardiovascular disease.

Abstract
BACKGROUND Rheumatoid arthritis is characterised by inflammation and an increased cardiovascular risk. It was recently shown that active early rheumatoid arthritis is associated with dyslipidaemia, which may partially explain the enhanced cardiovascular risk. However, it is unknown when this dyslipidaemia starts. OBJECTIVE To investigate the progression of the lipid profile over time and the influence of inflammatory parameters on this lipid profile, in people who later developed rheumatoid arthritis. METHODS Levels of total cholesterol, high-density lipoprotein cholesterol (HDLc), triglycerides, apolipoprotein AI (apo AI), apolipoprotein B (apo B) and lipoprotein(a) (Lp(a)) were determined in 1078 stored, deep-frozen, serial blood bank samples, collected between 1984 and 1999, of 79 blood donors who later developed rheumatoid arthritis. These samples were compared with 1071 control samples of unselected blood donors, matched for age, sex and storage time. RESULTS Samples of patients who later developed rheumatoid arthritis showed, on average, 4% higher total cholesterol, 9% lower HDLc, 17% higher triglyceride and 6% higher apo B levels than matched controls (p< or =0.05). The magnitude of the differences in lipid levels between groups, explained by C reactive protein (CRP), was limited. For example, only 3.6% of the difference in HDLc levels between the groups was explained by the CRP concentrations. CONCLUSION Patients who later develop rheumatoid arthritis have a considerably more atherogenic lipid profile than matched blood donors at least 10 years before onset of symptoms. As inflammation only marginally explains the differences between the two groups, a modulating effect of lipids on inflammatory processes is hypothesised.

Abstract
BACKGROUND Cardiovascular mortality is increased in patients with ankylosing spondylitis. A possible explanation might be a more prevalent atherogenic lipid profile in patients with ankylosing spondylitis than in the general population. It has been postulated that inflammation deteriorates the lipid profile, thereby increasing cardiovascular risk. OBJECTIVE To explore the association between disease activity and lipid profile in patients with ankylosing spondylitis. METHODS Disease activity parameters for ankylosing spondylitis and lipid levels (total cholesterol, high-density lipoprotein cholesterol (HDLc) and triglycerides) were measured in 45 patients with ankylosing spondylitis for 6 months after starting treatment with leflunomide or placebo. Findings in this treatment group were compared with those in 10 patients with ankylosing spondylitis treated with etanercept. A specialised regression model, adjusting for repeated measurements, age and sex, was used to assess the influence of the disease activity variables on the lipid levels. RESULTS Multilevel regression analyses showed significant associations between disease activity parameters and lipid levels-for instance, an increase of 30 mm at the end of the first hour in erythrocyte sedimentation rate was associated with a decrease of about 6% in total cholesterol level and a decrease of about 11% in HDLc levels. Similar significant associations were found between other disease activity parameters and lipid levels. CONCLUSION Increase in disease activity was associated with decreases in lipid levels. The decrease in HDLc levels tended to be almost twice as large as the decrease in total cholesterol levels, resulting in a more atherogenic lipid profile. Hence, effective treatment of disease activity in patients with ankylosing spondylitis may lower the cardiovascular risk by improving the lipid profile.

Abstract
OBJECTIVE To investigate the temporal relationship between onset of inflammation (as measured by secretory phospholipase A2 (sPLA2) and C reactive protein (CRP)) and the presence of autoantibodies (IgM rheumatoid factor (IgM RF) and antibodies against citrullinated peptides (anti-CCP)) in the preclinical phase of rheumatoid arthritis (RA). METHODS For 79 patients with RA who had been blood donors before the onset of disease, a median of 13 serum samples per patient was available. sPLA2 was measured in patient and matched control samples and related to previous CRP, IgM RF, and anti-CCP measurements. The temporal relationship between the increased markers of inflammation and autoantibodies was analysed with time lag analysis. RESULTS IgM RF and anti-CCP concentrations were significantly associated (p<0.001) with concentrations of sPLA2, CRP, and the combination of sPLA2 and CRP at the same time point. However, we found no stronger association between the two autoantibody tests and the three inflammation measures 1, 2, and 3 years before or after a time point than for measurements at the same time, in the whole group or in subgroups of IgM RF and anti-CCP positive patients. CONCLUSION Both the acute phase response and autoantibody formation often develop years before the first symptoms of RA occur, and these phenomena are probably closely connected in time.

Abstract
OBJECTIVE To assess the efficacy and safety of leflunomide in active ankylosing spondylitis (AS) compared with placebo in a 24 week pilot study. METHODS In a single centre randomised, double blind, placebo controlled study, 45 patients with active AS were randomised to either leflunomide 20 mg daily (n=30) or placebo (n=15). Active disease was defined as a score of >or=4 on the Bath ankylosing spondylitis disease activity index (0-10), and pain of >or=4 on a visual analogue scale (0-10). The primary efficacy variable at week 24 was the 20% response rate, as recommended by the Assessments in Ankylosing Spondylitis (ASAS) working group. Secondary outcome variables included general wellbeing, metrology index, swollen joint count, erythrocyte sedimentation rate, and C reactive protein. RESULTS In all, 13 women and 32 men were studied. Demographic and disease indices were comparable between the two treatment groups at baseline. The rate of ASAS 20% responders was not significantly different: 27% in the leflunomide treated patients and 20% in the placebo group (95% confidence interval, -32% to 19%). No significant differences were found between the treatment groups in mean changes of the secondary outcome variables. Eleven patients were withdrawn prematurely from the study because of adverse events (7), lack of efficacy (3), and non-compliance (1). Most frequently adverse events were gastrointestinal side effects and skin disorders. CONCLUSIONS In this placebo controlled study, leflunomide treatment did not result in a significant improvement of the ASAS 20% response in active ankylosing spondylitis. No unexpected or severe adverse events occurred.

Abstract
BACKGROUND Genetic factors are thought to be crucial in the pathogenesis of ankylosing spondylitis. Transforming growth factor beta 1 (TGF beta 1) is a multifunctional cytokine that plays a key role in inflammation. Two functional single nucleotide polymorphisms (SNPs) in the TGFB1 gene have been described: TGFB1 T869C and TGFB1 G915C. OBJECTIVE To determine whether these SNPs contribute to ankylosing spondylitis susceptibility or its disease characteristics. METHODS Genomic DNA was isolated from the peripheral blood of 134 patients with ankylosing spondylitis and 194 healthy blood donors. All subjects were unrelated and of white Dutch ethnicity. The diagnosis of ankylosing spondylitis was made according to the modified New York criteria. The TGFB1 T869C and TGFB1 G915C SNPs were genotyped by a polymerase chain reaction-single strand conformation polymorphism haplotyping method. RESULTS No significant differences were found between patients and controls in genotype, allele, and haplotype frequencies or in the carrier rate of the rare alleles of the TGFB1 T869C and TGFB1 G915C SNPs. CONCLUSIONS TGFB1 T869C and TGFB1 G915C SNPs are not major factors in the susceptibility to ankylosing spondylitis or its disease characteristics.

Abstract
In some conditions e.g. osteoporosis, hypertension and hypercholesterolaemia, certain phenomena precede manifestation of the disease and preventive measures can be taken long before the disease presents itself. In the same way systemic lupus erythematosus (SLE) and rheumatoid arthritis can be explored. Recently, studies have been published on healthy blood donors, who later developed SLE or rheumatoid arthritis, and in whom specific autoantibodies could be demonstrated. In SLE the autoantibodies are not specific enough to develop preventive strategies, but in rheumatoid arthritis in particular there are specific antibodies against cyclic citrullinated peptides (anti-CCP-antibodies) which are very specific. A clinical trial has been initiated in which HLA-DR4-positive people with raised autoantibody concentrations are given 1-2 intramuscular injections of dexamethasone with the aim of halving the antibody concentration and in the long term lowering the incidence of rheumatoid arthritis.

Abstract
OBJECTIVES Ankylosing spondylitis (AS) is a multifactorial and polygenic disease. Apart from HLA, other genes very probably play a role in disease susceptibility. Indigenous bacteria of the gastrointestinal flora appear to play a role in the pathogenesis of the disease; therefore, genes controling the innate and acquired immune response are good candidates to study disease susceptibility. CD14 and Toll-like receptor 4 (TLR4) are key receptors for the sensing of bacteria. The CD14 C-260T and TLR4 A896G single nucleotide polymorphims are associated with aberrant signal transduction for bacterial agonists. METHODS The distribution of the CD14 C-260T and TLR4 A896G polymorphisms was studied in genomic DNA from 113 unrelated white Dutch AS patients and 170 ethnically matched healthy controls. The diagnosis of AS was made according to the modified New York criteria. The CD14 C-260T and TLR4 A896G polymorphisms were genotyped by PCR-RFLP methods. RESULTS No significant differences were found between patients and controls in the frequencies of the carriership of the less frequent CD14-260T allele (odds ratio 0.65; 95% confidence interval 0.37 to 1.15) or the TLR4 896G allele (1.68; 0.67 to 4.19). CONCLUSIONS There is no evidence for involvement of the CD14 C-260T or TLR4 A896G polymorphisms in susceptibility to AS. An important role of bacteria and genetic predisposition of the innate immune system in cases of AS cannot be excluded by these findings. Therefore, studies of the surprisingly highly polymorphic candidate genes in this field should be continued.

Abstract
BACKGROUND The anti-cyclic citrullinated peptide (CCP) test has a high sensitivity and specificity for rheumatoid arthritis, although CCP is not the physiological target of the autoantibodies. Citrullinated fibrin is abundant in inflamed synovium OBJECTIVE To assess the diagnostic and prognostic value of antibodies against citrullinated fibrinogen (ACF), a soluble precursor of fibrin, in comparison with IgM-rheumatoid factor (IgM-RF) and the second generation anti-CCP test. METHODS In 379 patients with early arthritis (258 rheumatoid and 121 undifferentiated), the sensitivity, specificity, and positive predictive value of ACF, anti-CCP, and IgM-RF for diagnosing rheumatoid arthritis were calculated. Multivariate logistic regression analysis was used to assess the diagnostic and prognostic value (radiographic progression after two years) of the tests. RESULTS The sensitivities of the ACF, anti-CCP, and IgM-RF tests were 55.8%, 57.8%, and 44.6%, with specificities of 92.6%, 94.2%, and 96.7%, respectively. Approximately 30% of the IgM-RF negative patients were positive for ACF or anti-CCP or both. The ACF and anti-CCP test had a high agreement in early arthritis (kappa = 0.84). Of all baseline characteristics, the ACF test and the anti-CCP test were the best predictors for diagnosing rheumatoid arthritis at one year (odds ratio (OR) = 10.3 and 10.6, respectively) and for radiographic progression after two years (OR = 12.1 and 14.8). CONCLUSIONS ACF is as sensitive as anti-CCP and more sensitive than IgM-RF in diagnosing rheumatoid arthritis in early arthritis. The ACF test is also a good predictor of radiographic progression, with a performance similar to the anti-CCP test. The ACF test and the anti-CCP test are especially valuable in IgM-RF negative arthritis.

Abstract
OBJECTIVE Many early arthritis clinics (EACs) have been started in the last decade in order to detect and treat rheumatoid arthritis early. The present study evaluates whether the disease activity at admission of patients with early oligo- and polyarthritis changed during the period 1993--1998 in two EACs in the Netherlands. METHODS Patients were selected who were diagnosed after one year as having rheumatoid arthritis (RA) or oligo- or polyarthritis (UPA), had a symptom duration of less than 2 years, and were referred from two Dutch EACs between 1993 and 1998. The data from the two clinics were combined and stratified by referral year. Differences in baseline disease characteristics as well as changes in radiological and functional scores after two years of follow-up between referral years were analysed by ANOVA using Bonferroni corrected p levels. RESULTS A total of 405 patients (66% females; median age 57 yrs (18-93): 80% diagnosed as RA, the remainder as UPA) were included in the study. The year-groups did not differ significantly in demographic characteristics or in the duration of complaints (median 6 months). The number of patients with a diagnosis of RA declined over the years, as did the mean baseline erythrocyte sedimentation rate (ESR), in RA and UPA patients. The functional status (Health Assessment Questionnaire: HAQ) was enhanced in 1998 compared with the previous years (p < 0.001). Radiographic progression (Sharp/van der Heijde score) after the 2-year follow-up decreased (p < 0.001) in the later referral years compared to the referral group of 1994. Disease modifying anti-rheumnatic drugs (DMARDs) were started in an earlier stage and the prescription rate of sulfasalazine and methotrexate increased over the years, whereas the number of patients not treated with DMARDs declined. CONCLUSION The pattern of patient referral changed over 6 years towards fewer patients who fulfilled the RA diagnosis and a lower ESR (among UPA as well as RA patients), whereas the number of swollen joints and the duration of complaints remained the same. The radiological progression declined over time, probably due to less inflammation at the first visit and the increased use of DMARDs.

Abstract
OBJECTIVE Establish the use of thromboprophylaxis in orthopaedic surgery both during and after the hospital admission. DESIGN Cross-sectional study. METHOD In April 2002, a letter was sent to all orthopaedic surgeons in the Netherlands announcing that at every hospital with a Department of Orthopaedic Surgery, an orthopaedic surgeon would be approached for a telephone survey. They were phoned in the months April-June 2002. This study included hospitals where major orthopaedic surgery (e.g. the insertion of hip or knee prostheses and hip fracture surgery) took place (n = 124) as well as clinics that only performed day treatments (n = 5). RESULTS For major orthopaedic operations, 91% of the hospitals used low molecular weight heparin (LMWH) during the admission period: 36% as monotherapy and 55% in combination with coumarin derivates. In 85% of cases the use of LMWH was started preoperatively. Coumarin derivates were used as a monotherapy in 9% of the hospitals. In 37% of the hospitals the use of NSAIDs was continued, particularly in patients with rheumatoid arthritis. In 94% of the hospitals, the use of acetylsalicylic acid was always stopped. In 97% of the hospitals prophylaxis was given after discharge in the form of LMWH (37% of the cases) or coumarin derivates (63% of the cases). The use of thromboprophylaxis with respect to arthroscopies and plaster immobilisation was variable.

Abstract
An insertion mutation at nucleotide 3020 (3020insC) and a missense mutation G2722C in the CARD15 gene on chromosome 16p have been reported to be associated with Crohn's disease (CD). The protein encoded by the CARD15 gene is expressed in peripheral monocytes and regulates apoptosis and NF-kappaB activation, factors which play an important role in inflammation. Since CD and ankylosing spondylitis (AS) are interrelated disorders, we have investigated whether these mutations in the CARD15 gene are also associated with AS. We studied 113 unrelated AS patients and 152 unrelated healthy controls. No significant differences were found between patients and controls in the prevalence of the insertion 3020insC mutation and the G2722C missense mutation, OR = 1.36, 95% CI: 0.27-6.84, P = 0.70 and OR = 0.58; 95% CI: 0.18-1.94; P = 0.38, respectively. We conclude that the insertion 3020insC mutation and the G2722C missense mutation in the CARD15 gene are not involved in the susceptibility to AS.

Abstract
OBJECTIVE Since ulcerative colitis and Crohn's disease, which are associated with ankylosing spondylitis (AS), have been found to be variably associated with the IL-1B and the IL-1RN genes encoding interleukin-1beta (IL-1beta) and the interleukin-1 receptor antagonist (IL-1ra), we have investigated whether these polymorphisms in IL-1B and IL-1RN are also involved in AS. METHODS DNA was isolated from peripheral blood of 106 patients with AS and 104 healthy controls. All patients and controls were Dutch Caucasians. Bi-allelic polymorphisms at positions +3,953 and -511 in the IL-1B gene, and a penta-allelic polymorphism in intron 2 of the IL-1RN gene were studied by polymerase chain reaction-based methods. RESULTS Allele IL-1RN*2 was significantly increased in AS (odds ratio=1.60; 95% confidence interval=1.20-2.80; P=0.031) compared with healthy controls, and independent from the polymorphism in loci IL-1B-511 and IL-1B+3,953. No significant associations were found between AS and the IL-1B-511 or IL-1B+3,953 polymorphisms. CONCLUSION Similar to other chronic inflammatory diseases, AS is associated with the IL-1RN*2 allele. Further studies are necessary to determine the biological significance of these findings in relation to susceptibility or severity of the disease.

Abstract
Ankylosing spondylitis (AS) is a common (prevalence 0.2-0.9%) chronic inflammatory disease that mainly affects young males and is characterised by inflammatory back pain with sacroiliitis and often arthritis of the peripheral joints. The disease can lead to deformities of the vertebral column, joints and extra-spinal structures, e.g. the eye (uveitis). Non-steroidal anti-inflammatory drugs (NSAIDs) and physical therapy seem to improve the long-term outcome of AS. However, the effect of disease modifying antirheumatic drugs (DMARDs) is less impressive compared with other rheumatic diseases, such as rheumatoid arthritis (RA). In placebo controlled trials, sulfasalazine showed some improvement of disease activity, especially in spondyloarthropathy patients with peripheral arthritis. Altogether the number of therapeutic options for AS is limited and other drugs, such as leflunomide or thalidomide, should be explored further in placebo-controlled trials.

Abstract
OBJECTIVE To identify variables that can predict a progressive outcome after one year of follow up in patients presenting with undifferentiated polyarthritis (UPA) at an early arthritis clinic. METHODS New patients with arthritis in two or more joints of less than three years' duration were categorised at entry as UPA or as rheumatoid arthritis (RA) based on the clinical diagnosis of the rheumatologist. Outcome variables after one year were radiographic damage (Sharp/van der Heijde score) and functional status (Health Assessment Questionnaire: HAQ score). A progressive disease at one year was defined as radiographic progression > or =4, or one year radiographic damage > or =10, or HAQ score > or =1. The baseline variables of patients with UPA with a progressive or mild outcome were compared. RESULTS 280 patients (70% women; median age 56 years (range 18-90), median duration of symptoms 3.5 months) were included. 203 (72%) patients were clinically diagnosed as having RA and 77 (27%) as having UPA. The group of patients with progressive UPA (n=32 (42%)) had a significantly higher mean age, prevalence of arthritis of the hands, and disease activity (DAS28) at the first visit compared with the patients of the mild UPA group (n=45 (58%)). The RA group had significantly more frequent serum IgM-RF positivity, higher mean disease activity (DAS28) and mean C reactive protein concentration, more frequent symmetric arthritis, and arthritis in more than three joint groups than the progressive UPA group. Six (19%) of the progressive UPA group versus eight (4%) of the RA group did not receive disease modifying antirheumatic drugs during the first year. CONCLUSIONS After one year of follow up, 32 (42%) of the patients with UPA had a progressive disease. A progressive outcome was associated with older age, higher disease activity, and arthritis of the hands at baseline. To avoid undertreatment of patients with UPA, treatment should be based on severity rather than on diagnosis.

Abstract
BACKGROUND Several studies have reported an association between the presence of the shared epitope (SE) and susceptibility to rheumatoid arthritis (RA). Recent studies have shown that certain HLA-DRB1 alleles in combination with predisposing DQB1 and DQA1 alleles may protect against the development of RA. This model is known as the rheumatoid arthritis protection (RAP) hypothesis. OBJECTIVE To determine the distribution of HLA-DRB1 and DQB1/DQA1 alleles in a cohort of patients with RA in remission and to determine the association between these HLA alleles and the persistence of remission. PATIENTS AND METHODS HLA-DRB1 and DQB1 typings were performed in 167 patients with RA in remission, defined according to the American College of Rheumatology criteria. The disease course, as defined by the persistence of remission during a follow up of two years, was compared between subgroups. According to the RAP hypothesis patients were divided into three subgroups: patients carrying predisposing DQ alleles, patients carrying predisposing alleles in combination with protective alleles (DQ(RA+)/DERAA phenotype), and patients lacking the predisposing alleles. According to the SE hypothesis, patients were divided into three subgroups based on whether they were carrying two, one, or no predisposing alleles (SE alleles). RESULTS Predisposing DQ alleles along with a DERAA-bearing allele were present in 14 (8%) of the 167 patients. At least one SE allele was present in 116 (69%) patients; 34 of them (20%) were carrying two copies. The disease course was not significantly different between the subgroups according to the SE and RAP hypothesis, respectively. CONCLUSION The frequency of DQ(RA+)/DERAA combinations and of SE alleles in patients with RA clinically in remission was similar to that found in other RA populations. Persistent remission of RA was not associated with any particular HLA subtypes, indicating that HLA typing is not useful for predicting persistent clinical remission.

Abstract
OBJECTIVE To determine factors at diagnosis, associated with radiographic damage at diagnosis and after one year, in patients with early rheumatoid arthritis (RA). METHODS New patients with early RA were followed up for one year. Possible prognostic factors were duration of complaints, morning stiffness, disease activity score (DAS28), functional status (Health Assessment Questionnaire (HAQ) score), rheumatoid factor (IgM RF), and C reactive protein (CRP). Outcome was defined as radiographic damage of the hands and feet (Sharp/van der Heijde score). For the statistical analysis, one way analysis of variance and a forward stepwise logistic regression model was used. RESULTS 130 patients with RA (68% female; median age 64 years, range 21-86) were included. Despite the fact that the median duration of complaints was short (15 weeks, range 2-106) the radiographic damage at diagnosis was significantly correlated with the duration of complaints (p<0.05). Patients with a duration of complaints of >34 weeks had significantly more radiographic joint damage at diagnosis than patients with a shorter duration of complaints. Radiographic progression at one year was correlated with high radiographic joint damage, high CRP level, and a positive IgM RF at entry. CONCLUSIONS In early RA, the number of radiographic lesions was correlated with a longer duration of complaints at the first visit. Progression of these lesions was predicted by a high baseline joint damage, high CRP level, and a positive IgM RF. Further reduction of the delay in referral and early treatment may further decrease joint damage in patients with recent onset polyarthritis.

Abstract
OBJECTIVE To analyse the distribution of predisposing DQ3 (DQB1*03(*04)/DQA1*03) and DQ5 (DQB1*0501/DQA1*01), shared epitope encoding and protective DRB1 alleles in patients with early rheumatoid arthritis (RA) and undifferentiated arthritis (UA). METHODS Consecutive patients enrolled in an early arthritis clinic were DNA-typed for HLA-DQ and DR. RA patients (n=195), UA patients (n=160) and controls from the same region (n=306) were sorted according to their DQ-DR phenotypes: DQ3 vs DQ5 and the presence or absence of a protective DERAA-positive DRB1 molecule. The three groups were also sorted according to the shared epitope (SE) hypothesis. RESULTS We observed the association of both DQ3 and DQ5 with RA. DQ3/3 homozygous individuals had the highest risk of developing disease [odds ratio (OR)=20.00]. Conversely DQ5, but not DQ3, was associated with undifferentiated arthritis (OR=2.15 vs 1.25). Consistent with these differences, DQ3-positive individuals had significantly more active disease at the first visit at the outpatient clinic than DQ5-positive patients. DRB1 alleles encoding a DERAA motif in their third hypervariable region provided a strong dominant protection against RA among DQ5-positive individuals and decreased arthritis activity among DQ3-positive patients. Individuals with SE-positive DR1, DR4 and DR10 alleles were also predisposed to RA, DR4/4 homozygous individuals having the highest risk of developing RA (OR=11.00). CONCLUSION The DQ3-DR4/9 haplotypes are associated with RA. The DQ5-DR1/10 haplotypes are associated with less active disease, i.e. UA, and DERAA encoding DRB1 alleles modulate either predisposition to or the severity of RA. We propose that HLA polymorphism influences not only the initiation or perpetuation of RA but also protection against the disease.

Abstract
OBJECTIVE Studies in mice have demonstrated an increased risk of ankylosing enthesopathy in earlier litters compared with later-born offspring. In humans, birth order and maternal age as risk factors for ankylosing spondylitis (AS) have not been investigated previously. This study was undertaken to investigate whether first-born children have a higher risk of AS than later-born children and whether maternal age at delivery is another risk factor. METHODS The birth order of 162 AS patients was compared with that of their healthy siblings, both for the total group and with stratification for maternal age at first delivery. Maternal age at the time of delivery of AS patients who were first-born children was compared with the mean maternal age at first delivery in the Dutch population. RESULTS The number of first-born children with AS was significantly higher than would be expected in case of an equal risk between first-born and later-born children (26 versus 20 for families with 2 children [P = 0.029] and 63 versus 47.6 for all families [P = 0.004]). Also, the mean maternal age at first delivery was lower in mothers of AS patients (24.8 years) compared with mothers of healthy controls (26.1 years). CONCLUSION Low birth order is a risk factor for AS in humans.
