RESUMEN
BACKGROUND: Increasing epidemiological evidence suggests associations between psoriasis, psoriatic arthritis (PsA) and metabolic disease. Elucidating the complex relationship between these comorbidities may have important management implications. OBJECTIVE: The aim of this study was to examine the difference in prevalence of metabolic disease burden between patients with psoriasis who lack arthritic manifestations (PsO) and PsA patients. METHODS: We performed a cross-sectional study in 123 patients with PsO and PsA. Metabolic syndrome was defined using the new criteria developed by the International Diabetes Foundation (IDF) in 2004. Therefore, clinical examination and standard survey were performed and fasting blood samples were collected. RESULTS: One hundred and four patients were analysed, of which 49 were PsO and 55 were PsA patients. We found that prevalence of the metabolic syndrome according to the IDF criteria was significantly higher in the PsO (44.9%) compared with the PsA group (25.5%) (P = 0.037). Looking closer at the individual components of the metabolic syndrome, this difference can mainly be attributed to the significantly higher prevalence of abdominal obesity in PsO (83.7%) vs. PsA (65.5%) (P = 0.034). For other individual components of the metabolic syndrome such as triglycerides, high-density lipoproteins, hypertension and plasma glucose, we could not show statistically significant differences between the groups. CONCLUSION: Metabolic syndrome is more prevalent in patients with PsO than in PsA patients, mainly determined by the higher prevalence of abdominal obesity in PsO compared with PsA group.

OBJECTIVE AND IMPORTANCE: We report on a rare case of septic arthritis of the sacroiliac joint in a young patient without apparent predisposing factors. CLINICAL PRESENTATION: A 22-year-old female presented with severe right pelvic and gluteal pain and systemic illness. She had a recent diagnosis of bilateral sacroiliitis. INTERVENTION: Systemic illness quickly subsided after initiation of intravenous antibiotic treatment. Subsequently, gluteal pain gradually diminished. CONCLUSION: Pyogenic sacroiliitis should be taken into account in patients with sacroiliitis and fever onset. Magnetic resonance imaging shows signal anomalies well beyond disappearance of symptoms, which may or may not require prolonged antibiotic therapy.

Currently, there is a 5 to 7 years gap between the first symptoms and the diagnosis of ankylosing spondylitis. A better patient referral might reduce this gap and accelerate the adequate treatment implementation. The study objective was to compare 2 referral strategies used in first line. In Belgium, 208 referral physicians assigned to 16 rheumatology centres were randomized to refer chronic back pain patients (with onset <45 years) using 1 of the 2 referral strategies: Strategy 1 :1 of 3 criteria (inflammatory back pain, HLA-B27, sacroiliitis on imaging); or Strategy 2: 2 of6 criteria (IBP inflammatory back pain, HLA-B27, sacroiliitis, family history, good response to NSAIDs, extra-articular manifestations). Among the 141 referred patients with strategy 1 and 2, 26.0 and 36.9% respectively were diagnosed with Axial Spondylarthritis (SpA). Inflammatory back pain, sacroiliitis and good respond to NSAIDs were the most frequently used criteria (92.9 %, 36.2 % and 33.3% respectively). This study emphasizes the high prevalence of undiagnosed axial SpA in patients with chronic back pain and stressed the necessity to increase awareness of the disease.

BACKGROUND: Vascular endothelial growth factor (VEGF-A) and placental growth factor (PlGF) are major regulators of pathological angiogenesis, which is a prominent feature of both Crohn's disease (CD) and peripheral synovitis in spondyloarthritis. OBJECTIVE: To investigate the presence of VEGF-A and PlGF in the gut of spondyloarthritis patients and to link this finding with subclinical gut inflammation in these patients. METHODS: Intestinal biopsies from healthy controls, CD patients, spondyloarthritis patients with or without subclinical gut inflammation and rheumatoid arthritis (RA) patients were stained for VEGF-A, PlGF, CD31 and vascular cell adhesion molecule 1 (VCAM-1) and digitally analysed. RESULTS: Spondyloarthritis patients with subclinical gut inflammation had markedly increased intestinal VEGF-A expression (p<0.001), mucosal vascularisation (p<0.001) and VCAM-1 expression (p<0.01) compared with healthy controls and RA patients, which, unlike in CD patients, was also seen when the gut inflammation was in a quiescent state. PlGF expression was highly increased in the subclinically inflamed gut of spondyloarthritis (p<0.01 compared with healthy controls), but not at all in CD. CONCLUSION: A pro-angiogenic intestinal phenotype is observed in spondyloarthritis patients with quiescent chronic gut inflammation. This favours an environment for enhanced trafficking of immune cells in this subpopulation.

A 61-year-old woman with a history of systemic lupus erythematosus presented with a facial rash followed by fever. The diagnosis of lupus flare was made by the general practioner who prescribed corticosteroids. The evolution was unfavorable and the patient was hospitalized. On admission, she presented with high fever and a sharply demarcated papular erythema overlying her cheeks. Biology was inflammatory with elevated C-reactive protein, sedimentation rate and leucocyte count. The diagnosis of erysipelas of the face was made on the basis of the malar and non pruritic papular erythema, fever, the high C-reactive protein levels and the absence of response to corticosteroids. The evolution was favorable under intravenous antibiotics and rapid tapering of the corticosteroids. To our knowledge, this is the first report of facial erysipelas in a patient with a history of systemic lupus erythematosus. This coincidence is a rare condition which may lead to erroneous diagnosis and inappropriate therapy.

OBJECTIVE: To evaluate the sensitivity and specificity of criteria designed for spondyloarthritis in a university hospital treated population of children with late onset pauciarticular juvenile chronic arthritis and a control population. METHODS: Four sets of criteria especially designed for juvenile patients: Garmisch-Partenkirchen juvenile spondylitis criteria (= Garmisch), SEA (=seronegative enthesopathy and arthritis) syndrome, Enthesitis Related Arthritis (ERA), Atypical spondyloarthritis for children and two sets of criteria for patients without age specification (European spondyloarthropathy Study Group - ESSG and Amor) were evaluated in a cross-sectional way in a group of 43 consecutive patients with late onset pauciarticular juvenile chronic arthritis (LOPA) seen over a six-month period in the outpatient clinic. These criteria were analysed in 69 patients with other forms of juvenile chronic arthritis as well. The sensitivity and specificity were calculated for each set, as well as positive predictive value and likelihood ratio. The characteristics described in the different sets of criteria were separately evaluated in the LOPA patients and the other patients. RESULTS: For sensitivity, the Garmisch criteria scored the highest value (97.7%). However, sensitivity was significantly lower in two of the juvenile sets (SEA syndrome and Atypical spondyloarthritis), respectively 44.2% and 51.2%, as opposed to the other criteria (>85%; p<0.01 by Mc Nemar test). Specificity and positive predictive value (PPV) was the highest for the SEA syndrome criteria (98.5%, vs. 95.0%) followed by the ERA (95.6 % vs. 92.1 %) and the Garmisch criteria (94.2% vs. 91.3%). The positive likelihood ratio (LR+) was >10 in SEA (30.5), ERA (18.7) and Garmisch (16.8). The negative likelihood ratio (LR-) was <0.1 only in the Garmisch criteria (0.02). CONCLUSION: Sensitivity, specificity, PPV, LR+ and LR- for the Garmisch-Partenkirchen criteria suggest that they classify almost the same population as defined by LOPA. The SEA syndrome criteria, which were not designed to be classification criteria, being very specific, cannot be used in this patient population to classify a sufficient number of patients. The sensitivity and specificity for the ESSG criteria being similar in these children as in adults suggest they have similar characteristics. The Garmisch-Partenkirchen criteria and/or LOPA definition are major candidates for future research in identifying spondyloarthritis in juvenile patients.

Rheumatoid arthritis and spondyloarthritis, a concept which includes diseases like ankylosing spondylitis, psoriatic arthritis, and arthritis/spondylitis associated with inflammatory bowel disease, are both chronic inflammatory rheumatologic conditions. This article focuses on extra-articular manifestations, defined as diseases and symptoms not directly related to the locomotor system. The different manifestations are addressed per body system. Diagnostic and prognostic implications of these manifestations in daily practice are discussed.

OBJECTIVES: The risk for disease or a bad prognosis can be calculated by means of prediction or classification models that take into account multiple variables. Different methods exist to construct such models. Some of those methods, including the likelihood ratio (LR) product method neglect dependency between variables. We aimed to evaluate the effect of neglecting dependency between variables in prediction or classification models. PATIENTS AND METHODS: Population I consisted of 1003 consecutive patients with a new diagnostic problem for which RA was included in the differential diagnosis and final diagnoses (RA or non-RA) were established after 1 year. The baseline variables included in the model are rheumatoid factor, anti-citrullinated protein/peptide antibodies and the HLA-shared epitope. Population II consisted of 847 patients with definite ankylosing spondylitis (AS). Six variables (psoriasis, inflammatory bowel disease, uveitis, HLA-B27 status and latest available CRP) were evaluated. Here, specificities of the features were derived from literature and different scenarios of association between variables in controls and diseased are estimated. RESULTS: When two features are similarly associated in cases and controls, risks for disease will be overestimated by neglecting dependency between variables. In the presented datasets, this resulted in a up to 12% overestimation of the risk. CONCLUSIONS: We showed how the height of over- or underestimation of risks can be evaluated when dependencies between two variables are neglected. This is important to evaluate the predictive value of combinations of features in cases where no data are available on associations in controls.

OBJECTIVE: To validate and refine two sets of candidate criteria for the classification/diagnosis of axial spondyloarthritis (SpA). METHODS: All Assessment of SpondyloArthritis international Society (ASAS) members were invited to include consecutively new patients with chronic (> or =3 months) back pain of unknown origin that began before 45 years of age. The candidate criteria were first tested in the entire cohort of 649 patients from 25 centres, and then refined in a random selection of 40% of cases and thereafter validated in the remaining 60%. RESULTS: Upon diagnostic work-up, axial SpA was diagnosed in 60.2% of the cohort. Of these, 70% did not fulfil modified New York criteria and, therefore, were classified as having "non-radiographic" axial SpA. Refinement of the candidate criteria resulted in new ASAS classification criteria that are defined as: the presence of sacroiliitis by radiography or by magnetic resonance imaging (MRI) plus at least one SpA feature ("imaging arm") or the presence of HLA-B27 plus at least two SpA features ("clinical arm"). The sensitivity and specificity of the entire set of the new criteria were 82.9% and 84.4%, and for the imaging arm alone 66.2% and 97.3%, respectively. The specificity of the new criteria was much better than that of the European Spondylarthropathy Study Group criteria modified for MRI (sensitivity 85.1%, specificity 65.1%) and slightly better than that of the modified Amor criteria (sensitivity 82.9, specificity 77.5%). CONCLUSION: The new ASAS classification criteria for axial SpA can reliably classify patients for clinical studies and may help rheumatologists in clinical practice in diagnosing axial SpA in those with chronic back pain. TRIAL REGISTRATION NUMBER: NCT00328068.

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.

OBJECTIVE: Inflammatory back pain (IBP) is an important clinical symptom in patients with axial spondyloarthritis (SpA), and relevant for classification and diagnosis. In the present report, a new approach for the development of IBP classification criteria is discussed. METHODS: Rheumatologists (n = 13) who are experts in SpA took part in a 2-day international workshop to investigate 20 patients with back pain and possible SpA. Each expert documented the presence/absence of clinical parameters typical for IBP, and judged whether IBP was considered present or absent based on the received information. This expert judgement was used as the dependent variable in a logistic regression analysis in order to identify those individual IBP parameters that contributed best to a diagnosis of IBP. The new set of IBP criteria was validated in a separate cohort of patients (n = 648). RESULTS: Five parameters best explained IBP according to the experts. These were: (1) improvement with exercise (odds ratio (OR) 23.1); (2) pain at night (OR 20.4); (3) insidious onset (OR 12.7); (4) age at onset <40 years (OR 9.9); and (5) no improvement with rest (OR 7.7). If at least four out of these five parameters were fulfilled, the criteria had a sensitivity of 77.0% and specificity of 91.7% in the patients participating in the workshop, and 79.6% and 72.4%, respectively, in the validation cohort. CONCLUSION: This new approach with real patients defines a set of IBP definition criteria using overall expert judgement on IBP as the gold standard. The IBP experts' criteria are robust, easy to apply and have good face validity.

BACKGROUND: The ASAS/EULAR (Assessment of SpondyloArthritis International Society/European League Against Rheumatism) recommendations for the management of ankylosing spondylitis (AS) have been developed by rheumatologists for a target population of health professionals. OBJECTIVE: To extend the cooperation between ASAS and EULAR by translating the recommendations into a language that can be easily understood by patients in order to further disseminate and evaluate the recommendations. METHODS: In cooperation with patient organisations 18 patients with AS (17 European, one Canadian) were invited to attend a meeting in February 2008. As a starting point the original publication and a version created by Canadian patients with AS were used. To improve the understanding of potential problems, data on the evaluation of a recent German translation were presented. After intensive discussions the wording was adjusted and a vote was held on the new wording of the recommendations aiming for >80% agreement on each sentence. Finally, patients were asked to indicate their level of agreement with the content of the recommendations. RESULTS: Ten recommendations were successfully translated into a patient-understandable version. The original text was changed in most cases. In all but one case (recommendation No 4) there was broad agreement with the proposed translation. The overall agreement with the content of the recommendations was high: 8.7 (0.6). CONCLUSION: For the first time, EULAR recommendations were successfully converted into a patient-understandable language version by a large international group of patients in collaboration with rheumatologists. The evaluation showed broad agreement. Translations into different languages and further dissemination in individual countries will be performed.

AIM: To study the relationship between disease activity, radiographic damage and physical function in patients with ankylosing spondylitis (AS) PATIENTS AND METHODS: Baseline and 2-year data of the Outcome in Ankylosing Spondylitis International Study (OASIS)(217 patients) were used. Physical function was expressed by the Bath Ankylosing Spondylitis Functional Index (BASFI) and the Dougados Functional Index (DFI); disease activity by the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and by erythrocyte sedimentation rate and C-reactive protein; and structural damage by the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS). Syndesmophyte- and non-syndesmophyte sum cores, and numbers of affected (bridged) vertebral units were derived from the mSASSS. Univariate correlations were calculated on baseline values using the Spearman rank correlation. Multivariate associations were investigated by generalised estimating equations (GEE) on baseline and 2-year data. RESULTS: mSASSS correlated moderately well with BASFI (Spearman's r = 0.45) and DFI (r = 0.38). BASDAI correlated well with BASFI (r = 0.66) and DFI (r = 0.59). Correlation coefficients for mSASSS versus BASFI and DFI decreased by increasing levels of BASDAI, being zero at the highest quintile of BASDAI. GEE showed that both BASDAI and mSASSS independently and significantly helped to explain either BASFI or DFI. Results were similar for syndesmophyte sum score, non-syndesmophyte sum score, number of affected VUs or number of VUs with bridging. The lumbar part of the mSASSS contributed similarly to the cervical part in explaining BASFI/DFI. CONCLUSION: Physical function impairment in AS is independently caused by patient-reported disease activity and the level of structural damage of the lumbar and cervical spine. Syndesmophytes and other radiographic abnormalities contribute to physical function impairment.

OBJECTIVES: To develop evidence-based recommendations for the use of methotrexate in daily clinical practice in rheumatic disorders. METHODS: 751 rheumatologists from 17 countries participated in the 3E (Evidence, Expertise, Exchange) Initiative of 2007-8 consisting of three separate rounds of discussions and Delphi votes. Ten clinical questions concerning the use of methotrexate in rheumatic disorders were formulated. A systematic literature search in Medline, Embase, Cochrane Library and 2005-7 American College of Rheumatology/European League Against Rheumatism meeting abstracts was conducted. Selected articles were systematically reviewed and the evidence was appraised according to the Oxford levels of evidence. Each country elaborated a set of national recommendations. Finally, multinational recommendations were formulated and agreement among the participants and the potential impact on their clinical practice was assessed. RESULTS: A total of 16 979 references was identified, of which 304 articles were included in the systematic reviews. Ten multinational key recommendations on the use of methotrexate were formulated. Nine recommendations were specific for rheumatoid arthritis (RA), including the work-up before initiating methotrexate, optimal dosage and route, use of folic acid, monitoring, management of hepatotoxicity, long-term safety, mono versus combination therapy and management in the perioperative period and before/during pregnancy. One recommendation concerned methotrexate as a steroid-sparing agent in other rheumatic diseases. CONCLUSIONS: Ten recommendations for the use of methotrexate in daily clinical practice focussed on RA were developed, which are evidence based and supported by a large panel of rheumatologists, enhancing their validity and practical use.

OBJECTIVE: Recommendations and/or guidelines represent a popular way of integrating evidence-based medicine into clinical practice. The 3E Initiatives is a multi-national effort to develop recommendations for the management of rheumatic diseases, which involves a large number of experts combined with practising rheumatologists addressing specific questions relevant to clinical practice. METHODS: Ten countries participated in three rounds of discussions and votes concerning the management of AS. A set of nine questions was formulated in the domains of diagnosis, monitoring and treatment, after a Delphi procedure. A literature search in MedLine was conducted. Predefined outcome parameters for the domains of diagnosis, monitoring and treatment were assessed. The evidence to support each proposition was evaluated and scored. After discussion and votes, the final recommendations were presented using brief statements by each national group, following which the final international recommendations were formulated. RESULTS: A total of 2699 papers were found and 467 were selected for analysis. Twelve key recommendations were developed: three in the domain of diagnosis addressing general diagnostic considerations, early AS diagnosis and general practitioners' referral recommendations; three concerning monitoring of AS disease activity, severity and prognosis; six concerning pharmacological treatment (except biologics): non-steroidal anti-inflammatory drugs/COX-II inhibitors, bisphosphonates and treatment of enthesitis. The compiled agreement among experts ranged from 72% to 93%. CONCLUSION: Recommendations for the management of AS were developed using an evidence-based approach followed by expert/physician consensus with high level of agreement. Involvement of a larger and more representative group of rheumatologists may improve their dissemination and implementation in daily clinical practice.

Brucellosis is a common zoonosis which still remains a major health problem in certain parts of the world. Osteoarticular involvement is the most frequent complication of brucellosis, in which the diagnosis of brucellar spondylodiscitis is often difficult since the clinical presentation may be obscured by many other conditions. Herein, we report an uncommon case of spondylodiscitis due to Brucella in a male who presented with abdominal pain. The diagnosis was established by positron emission tomography combined with computed tomography (PET/CT scan) and magnetic resonance followed by a confirmation on Brucella-agglutination test and positive culture of computed tomography (CT) guided punction fluid. This case report illustrates an atypical presentation of spondylitis and points out the difficulties in diagnosing the aetiological agens Brucella and differentiating its specific features from tuberculosis.

OBJECTIVES: To determine the type and proportion of patients with ankylosing spondylitis who rheumatologists consider to be candidates for treatment with tumour necrosis factor (TNF)-blocking agents, and to what extent this is in agreement with the ASsessment in Ankylosing Spondylitis (ASAS) international working group recommendations on initiation of treatment with anti-TNF agents. METHODS: Participants were rheumatologists from 10 different countries, who were considered to be experts in treating patients with ankylosing spondylitis and in the use of anti-TNF treatment, but were unaware of the ASAS recommendations (unpublished at the time of study in 2003). The first 10 consecutive patients with ankylosing spondylitis seen by the rheumatologist were evaluated as to whether the patient was a candidate for anti-TNF treatment. Thereafter, a metrologist assessed the patient for disease activity and severity, and collected data on demographics and treatment. RESULTS: Complete data were available for 1207 of the 1284 patients and were used for analysis. Overall, the rheumatologists indicated that they would initiate TNF-blocking agents in 49.3% of patients, ranging from 37.2% patients in Canada to 78.3% in Australia. These candidates had higher disease activity, higher levels of acute-phase reactants, worse spinal mobility, worse function, more often hip involvement and a higher prevalence of sick leave. Of all patients considered to be candidates, 40% did not fulfil ASAS recommendations with respect to previous use of non-steroidal anti-inflammatory drugs (NSAIDs; at least two NSAIDs) or Bath Ankylosing Spondylitis Disease Activity Index (>or=4). Conversely, 36% of patients who did not fulfil the NSAID or BASDAI recommendations were still considered to be candidates for TNF-blocking treatment. OBJECTIVE: variables, such as C reactive protein, erythrocyte sedimentation rate or magnetic resonance activity, were considered less important than disease activity in the decision on starting TNF-blocking drugs. The only important objective criterion was rapid radiographic progression. CONCLUSION: Rheumatologists wanted to initiate TNF-blocking drugs in roughly half of the patients with ankylosing spondylitis. However, there was a wide variation across countries and doctors. Rheumatologists considered both disease activity and severity to be determinants of starting TNF blockers, but their decision was often in disagreement with ASAS recommendations.
