Abstract: OBJECTIVE: To make recommendations on how to report disease activity in clinical trials of rheumatoid arthritis (RA) endorsed by the European League Against Rheumatism (EULAR) and the American College of Rheumatology (ACR). METHODS: The project followed the EULAR standardized operating procedures, which use a three-step approach: 1) expert-based definition of relevant research questions (November 2006); 2) systematic literature search (November 2006 to May 2007); and 3) expert consensus on recommendations based on the literature search results (May 2007). In addition, since this is the first joint EULAR/ACR publication on recommendations, an extra step included a meeting with an ACR panel to approve the recommendations elaborated by the expert group (August 2007). RESULTS: Eleven relevant questions were identified for the literature search. Based on the evidence from the literature, the expert panel recommended that each trial should report the following items: 1) disease activity response and disease activity states; 2) appropriate descriptive statistics of the baseline, the endpoints and change of the single variables included in the core set; 3) baseline disease activity levels (in general); 4) the percentage of patients achieving a low disease activity state and remission; 5) time to onset of the primary outcome; 6) sustainability of the primary outcome; 7) fatigue. CONCLUSION: These recommendations endorsed by EULAR and ACR will help harmonize the presentations of results from clinical trials. Adherence to these recommendations will provide the readership of clinical trials with more details of important outcomes, while the higher level of homogeneity may facilitate the comparison of outcomes across different trials and pooling of trial results, such as in meta-analyses.

Abstract: The field of inflammatory arthritis owes much to the advances in imaging technology which have enlightened not only clinical specialists but also researchers worldwide. The most exciting developments in recent decades have centred upon rheumatoid arthritis (RA) and more specifically the ultrasound (US) and magnetic resonance imaging (MRI) findings at various stages of the natural history of this condition. Investigation of RA using the standard techniques of plain radiography (x-ray) and more sophisticated computerised tomography (CT) have now been superseded by the exponential growth of use of US and MRI and this has been born out by the profusion of scientific papers published on these subjects.This paper aims to review the array of imaging modalities available as investigative tools to the rheumatologist when presented with various clinical scenarios by patients with RA.

Abstract: One of the largest challenges to the field of musculoskeletal ultrasonography is attempting to accurately quantify the changes seen in chronic arthritis. With advances in ultrasound technology, researchers have been increasingly exploring ways of more accurately assessing these changes and attempting to reach consensus with agreed scoring systems. This review presents the main scoring systems developed for quantifying sonographic findings indicative of synovitis and joint damage in patients with rheumatoid arthritis. Further investigation is required to attain international consensus on such scoring systems and to evaluate their impact on therapeutic decision-making.

Abstract: Despite its indubitable potential, ultrasonography still has limited diffusion in rheumatology related principally to the image acquisition process due to at least five main factors: the steep learning curve, lack of standardisation of the technique, intra- and inter-observer variability, time consumption and the high initial cost of top quality sonographic equipment. Of all these barriers, the first four are undoubtedly the most difficult to overcome. This review discusses the available evidence supporting the potential of three-dimensional ultrasound with high-frequency volumetric probe to overcome the first four barriers. The challenge to three-dimensional ultrasound is to prove itself to be a method that requires no particular skills that can be mastered in just a few minutes and is not operator-dependant [corrected]

Abstract: Musculoskeletal sonography (MSUS) has played a growing role in the diagnosis and management of rheumatic diseases, enabling the imaging of synovitis, bone erosion, and cartilage damage in the early phase of arthritis. "Dynamic" evaluation of tendons and help in guiding needle positioning in interventional manoeuvres are some of the other reasons for its success. MSUS, particularly when coupled with power Doppler (PD) examination, has recently been shown to be an efficient tool for monitoring disease activity and progression in rheumatoid arthritis, spondyloarthritis, crystal-related arthropathy, and osteoarthritis, with general consensus on its interesting results. More specifically, the PD signal has proved to be a simple and promising tool for short-term monitoring of synovial vascularity changes induced by steroids or biological agents in RA patients. MSUS has some limits, because of the physical properties of US and the quality of the equipment; it is, moreover, an operator-related imaging technique, with few standardized protocols. Future goals should be standardization of the examining approach in grey scale and Doppler ultrasound (US), including use of new equipment (3D US), extensive use in other fields (i.e. connective tissue diseases and vasculitis), and possible new applications (e.g. thoracic US).

Abstract: The clinical entity of secondary Sjögren's syndrome (SS) is controversial and the relationship with primary SS and other systemic autoimmune diseases is still far from being completely understood. In the last few years, proteomic approaches have been applied with a growing interest in the search for diagnostic biomarkers for many rheumatic diseases and it is possible that, in the near future, proteomic analysis of human saliva could help in distinguishing also primary from secondary SS. This review summarizes the state of the art of proteomic analysis of human saliva in the diagnosis of connective diseases focusing its advantages, limits and future perspectives.

Abstract: In the last few years, a growing interest has arisen in the application of proteomic analysis to rheumatic disease. Sjögren's syndrome is a systemic disease that affects exocrine glands directly, and is therefore expected to influence the composition of the whole human saliva and lachrymal fluid. Therefore, a rising number of studies have been performed in an attempt to characterize the salivary and lachrymal protein profiles of patients with Sjögren's syndrome by using a proteomic approach. This review summarizes the state of the art and the potential application of proteomics in the systematic search for diagnostic biomarkers in Sjögren's syndrome.

Abstract: The assessment of quality of care is becoming increasingly important, but as yet no standard set of measures to assess quality has been developed. The ACR Quality Measures Committee has selected the following areas of study to develop quality indicators: diagnostic/classification criteria, outcome measures/response criteria, treatment guidelines/management recommendations, definition of quality indicators, and definition of data collection systems. The aim of the present review is to evaluate existing guidelines and outcome measures concerning disease/activity monitoring, autoantibody and laboratory assessment, outcomes, and therapy in systemic lupus erythematosus (SLE) that could be used to define disease-specific quality indicators.Much data is available in the literature that could serve to define a starter set of quality indicators for SLE. Monitoring issues are discussed in the ACR and EULAR recommendations. As far as therapy is concerned, the ACR has provided indicators for rheumatoid arthritis that could also be applied to SLE, as well as indications for anti-malarial monitoring. The outcomes measures most frequently used in SLE are damage and death, but organ-specific definitions of outcome and response are being evaluated.The development of quality measures for SLE is just beginning; existing information could serve to construct a starter set of indicators such as the one proposed here. Certainly much progress will be made in the near future. A practical, user-friendly tool for physicians that will help them deliver high quality care to populations is also needed.

Abstract: The present review provides an update of the available data and discusses research issues of ultrasound (US) imaging in rheumatoid arthritis (RA).Currently the principal indications for using US in the assessment of patients with RA include: detection of sub-clinical synovitis, demonstration of bone erosion undetected by conventional radiography, detailed assessment of tendon pathology and guided injection and aspiration of joints and soft tissues. Future potential applications are likely to include short and long term therapy monitoring and early detection of cartilaginous changes in RA.The main priorities requiring the attention of investigators include: addressing validity issues, especially those related to criterion and discriminator validity, development of international consensus on scoring systems, evaluation of the role of power Doppler in the assessment of disease activity, development of a specific training programme for rheumatologists performing US and investigation of the potential of 3D US using a volumetric probe.

Abstract: The term undifferentiated connective tissue diseases is used to define conditions characterized by the presence of signs and symptoms suggestive of a systemic autoimmune disease that do not satisfy the classificative criteria for defined connective tissue diseases (CTD) such as systemic lupus erythematosus (SLE), Sjögren's syndrome (SS), rheumatoid arthritis (RA) and others. A small percentage of patients presenting with an undifferentiated profile will develop during the first year follow up of a full blown CTD, however an average of 75% will maintain an undifferentiated clinical course. These patients may be defined as having a stable undifferentiated connective tissue diseases (UCTD). The most characteristic symptoms of UCTD are represented by arthritis and arthralgias, Raynaud's phenomenon, leukopenia, while neurological and kidney involvement are virtually absent. Eighty percent of these patients have a single autoantibody specificity, more frequently anti-Ro and anti-RNP antibodies. Stable UCTD are considered as distinct clinical entities and therefore it has been proposed to define those conditions as UCTD. Classificative criteria have also been proposed and a work to better define them is still under way.

Abstract: This paper focuses on skin manifestations that can be observed in autoimmune diseases such as rheumatoid arthritis (RA), Sjögren syndrome (SS), dermatomyositis (DM) and Behçet syndrome (BS). In RA the most widely recognized skin lesion is the rheumatoid nodule. Other cutaneous manifestations can be observed either non-specific or related to the disease itself and/or to the commonly used drugs. Cutaneous manifestations are considered one of the most typical extraglandular features of primary SS, generally they are distinguished in vasculitic and non vasculitic lesions. Among non-vasculitc lesions, skin dryness (xerosis) has been shown to be very common in pSS while vasculitis lesions include typically flat and palpable purpura and urticarial vasculits. In DM the skin manifestations are also frequent and include a heliotrope rash (blue-purple discoloration) on the upper eyelids with edema, a flat red rash on the face and upper trunk, and erythema of the knuckles with a raised violaceous scaly eruption (Gottron rash). The most frequent mucocutaneous finding in BS is aphthous stomatitis which can not usually be differentiated from idiopatic reccurrent aphthous stomatitis on clinical grounds. The most typical skin manifestations are nodular lesions, which are commonly seen in BS and may be due to panniculitis [erythema nodosum (EN)-like lesions] or superficial thrombophlebitis.

Abstract: In the last few years management of rheumatoid arthritis (RA) has changed substantially due to the availability of new drugs and newer therapeutical strategies. Controlled randomised clinical trials (RCT) have allowed us to analyse the efficacy and safety of all these innovative approaches. Unfortunately, these RCTs are not free from criticisms and their rigid inclusion and exclusion criteria may increase the differences between the ideal patients enrolled and the majority of patients seen in standard clinical care. This review focuses on actual clinical practice, with particular attention on patient comorbidities and all the conditions which have been designated as exclusion criteria in the most important registration RCTs. We will attempt to provide an overview of the most widely used strategies in RA therapy.

Abstract: Classification criteria for Sjögren's syndrome (SS) were developed and validated between 1989 and 1996 by the European Study Group on Classification Criteria for SS, and broadly accepted. These have been re-examined by consensus group members, who have introduced some modifications, more clearly defined the rules for classifying patients with primary or secondary SS, and provided more precise exclusion criteria.

Abstract: OBJECTIVE: To evaluate the effectiveness and safety of adalimumab in patients with rheumatoid arthritis (RA) who previously discontinued tumour necrosis factor (TNF) antagonists for any reason in clinical practice. METHODS: ReAct (Research in Active Rheumatoid Arthritis) was a large, open-label trial that enrolled adults with active RA who had previously been treated with traditional disease-modifying anti-rheumatic drugs or biological response modifiers. Patients self-administered adalimumab 40 mg subcutaneously every other week for 12 weeks and were allowed to enter an optional long-term extension phase. Measures of adalimumab effectiveness included American College of Rheumatology (ACR) and European League Against Rheumatism (EULAR) response criteria, Disease Activity Score 28 (DAS28) and the Health Assessment Questionnaire Disability Index (HAQ DI). RESULTS: Of 6610 patients, 899 had a history of etanercept and/or infliximab therapy; these patients experienced substantial clinical benefit from adalimumab treatment. At week 12, 60% of patients had an ACR20 and 33% had an ACR50 response; 76% had a moderate and 23% had a good EULAR response. In addition, 12% achieved a DAS28 < 2.6, indicating clinical remission, and 13% achieved a HAQ DI score <0.5. The allergic adverse event rate, regardless of relationship to adalimumab, was 6.5/100-patient-years (PYs) in previously TNF-antagonist-exposed patients and 4.3/100-PYs in TNF-antagonist-naive patients. A multiple regression analysis indicated no statistically significantly increased risk of serious infections in patients who received prior TNF antagonists compared with TNF-antagonist-naive patients. CONCLUSION: In typical clinical practice, adalimumab was effective and well-tolerated in patients with RA previously treated with etanercept and/or infliximab.

Abstract: In the rheumatology literature, most of the available evidence on three-dimensional ultrasound (3D US) is related to the acquisition process and highlights the virtual operator independence and shortening of the US examination time. The main aim of this study was to compare 3D US using a high-frequency volumetric probe and conventional 2D US at the wrist and hand in patients with rheumatoid arthritis (RA). The 3D US examinations were performed using a Logiq 9 (General Electrics Medical Systems, Milwaukee, WI) with a high-frequency (8-15 MHz) volumetric probe. Overall, there is good-to-excellent agreement between the two modalities relating to both joint inflammation and bone erosion. This study is an initial step towards establishing a methodology necessary for developing multi-centre US studies which are aimed at assessing hand involvement in patients with RA.

Abstract: INTRODUCTION: A candidate gene approach, in a large case-control association study in the Dutch population, has shown that a 480 kb block on chromosome 4q27 encompassing KIAA1109/Tenr/IL2/IL21 genes is associated with rheumatoid arthritis. Compared with case-control association studies, family-based studies have the added advantage of controlling potential differences in population structure. Therefore, our aim was to test this association in populations of European origin by using a family-based approach. METHODS: A total of 1,302 West European white individuals from 434 trio families were genotyped for the rs4505848, rs11732095, rs6822844, rs4492018 and rs1398553 polymorphisms using the TaqMan Allelic discrimination assay (Applied Biosystems). The genetic association analyses for each SNP and haplotype were performed using the Transmission Disequilibrium Test and the genotype relative risk. RESULTS: We observed evidence for association of the heterozygous rs4505848-AG genotype with rheumatoid arthritis (P = 0.04); however, no significance was found after Bonferroni correction. In concordance with previous findings in the Dutch population, we observed a trend of undertransmission for the rs6822844-T allele and rs6822844-GT genotype to rheumatoid arthritis patients. We further investigated the five SNP haplotypes of the KIAA1109/Tenr/IL2/IL21 gene region. We observed, as described in the Dutch population, a nonsignificant undertransmission of the AATGG haplotype to rheumatoid arthritis patients. CONCLUSIONS: Using a family-based study, we have provided a trend for the association of the KIAA1109/Tenr/IL2/IL21 gene region with rheumatoid arthritis in populations of European descent. Nevertheless, we failed to replicate a significant association of this region in our rheumatoid arthritis family sample. Further investigation of this region, including detection and testing of all variants, is required to confirm rheumatoid arthritis association.

Abstract: OBJECTIVE: To use an evidence-based and consensus-based approach to elaborate recommendations on how to report disease activity in clinical trials of patients with rheumatoid arthritis (RA) endorsed by the European League Against Rheumatism (EULAR) and the American College of Rheumatology (ACR). METHODS: After an initial expert meeting, during which relevant research questions were identified, a systematic literature search was performed using Medline, Embase and the Cochrane Library as sources. To ensure literature retrieved was comprehensive, we emphasised search algorithms that were sensitive rather than specific. The results of the literature search were discussed by the expert panel, modified and expanded, and were used as the basis for the elaboration of the recommendation in the consensus process. Finally, an independent ACR panel approved these items with some minor modifications. RESULTS: The following pieces of evidence were obtained from the literature search: (1) timing and the sustaining of a response is relevant to achieve better outcomes; (2) composite disease activity indices have been used to define low disease activity and remission and these definitions have been validated as has the American Rheumatism Association (ARA) remission criteria. The "patient-reported symptom state" (PASS) is not yet well validated; (3) evidence was obtained to identify those measures, scales and patient-reported instruments, for which there is a documented association with relevant outcomes; (4) baseline disease activity is associated with disease activity levels at the end of follow-up; and (5) there was not sufficient evidence relating the added benefit of MRI or ultrasound over clinical assessments. Most data stemmed from observational studies rather than clinical trials and literature review was supplemented by input from experts. The results served as the basis for the elaboration of the seven recommendations by the experts. CONCLUSIONS: The approach based on scientific evidence from the literature as well as on expert input provided sufficient information to derive recommendations on reporting disease activity in RA clinical trials. The methodology, results and conclusions of this project were endorsed by EULAR and the ACR.

Abstract: OBJECTIVE: We recently showed, using a candidate gene approach in a case-control association study, that a 65-kb block encompassing tumor necrosis factor receptor-associated factor 1 (TRAF1) and C5 is strongly associated with rheumatoid arthritis (RA). Compared with case-control association studies, family-based studies have the added advantage of controlling potential differences in population structure and are not likely to be hampered by variation in population allele frequencies, as is seen for many genetic polymorphisms, including the TRAF1/C5 locus. The aim of this study was to confirm this association in populations of European origin by using a family-based approach. METHODS: A total of 1,356 western European white individuals from 452 "trio" families were genotyped for the rs10818488 polymorphism, using the TaqMan allelic discrimination assay. RESULTS: We observed evidence for association, demonstrating departure from Mendel's law, with an overtransmission of the rs10818488 A allele (A = 55%; P = 0.036). By taking into consideration parental phenotypes, we also observed an increased A allele frequency in affected versus unaffected parents (A = 64%; combined P = 0.015). Individuals carrying the A allele had a 1.2-fold increased risk of developing RA (allelic odds ratio 1.24, 95% confidence interval 1.04-1.50). CONCLUSION: Using a family-based study that is robust against population stratification, we provide evidence for the association of the TRAF1/C5 rs10818488 A allele and RA in populations of European descent, further substantiating our previous findings. Future functional studies should yield insight into the biologic relevance of this locus to the pathways involved in RA.

Abstract: Studies have demonstrated a familial aggregation of systemic and organ-specific autoimmune diseases. The aim of the present survey was to obtain, by patient interviews, a preliminary estimate of the prevalence of systemic and organ-specific autoimmune diseases among the first- and second-degree relatives of Caucasian patients with connective tissue diseases (CTD) or inflammatory arthritis followed at our unit. Between June 2007 and January 2008, 626 patients and 85 controls (patients with osteoarthritis, osteoporosis, or fibromyalgia) were interviewed. Three hundred ten patients (50%) versus 21 controls (25%) were found to have at least one relative affected with an autoimmune condition (p < 0.0001). The most common conditions were organ-specific autoimmune diseases: 160 (34%) autoimmune thyroid (AT) disease, 112 (24%) psoriasis, 21 vitiligo, and 19 insulin-dependent diabetes mellitus. Systemic autoimmune diseases were reported in 126 relatives: rheumatoid arthritis (66 cases, 14%), 16 sacroileitis, and CTD (43 cases). A significant difference was observed in the prevalence of AT disease between the relatives of the patients and controls (3% versus 0.5%). In conclusion, these data confirm the high prevalence of autoimmune conditions, particularly of AT disease, among the relatives of patients.

Abstract: The term undifferentiated connective tissue diseases (UCTD) is used to identify systemic autoimmune diseases not fulfilling classificative criteria for defined connective tissue diseases (CTD). Aim of the present study was to evaluate the evolution to defined CTD of an historical cohort of 91 UCTD patients followed at our Unit and to describe clinical and serological characteristics of stable UCTD patients with a disease duration of more than 5 years. Patients, previously described, were selected for having an undifferentiated profile after 1 year of follow up. These patients have been regularly followed at our Unit and their diagnosis has been reassessed annually based on the existing classificative criteria. Seven UCTD patients with a follow up of less than 5 years have been excluded from the study, therefore 84 patients (F: 81, M: 3) have been analysed. During the follow up 28 patients (33%) developed a defined CTD. In particular 22 patients developed systemic lupus erythematosus (SLE), while the remaining 6 patients developed other CTDs (2 primary Sjögren's syndrome, 2 overlap syndromes, 1 Systemic Sclerosis, 1 rheumatoid arthritis). The evolution to a defined CTD occurred after a mean disease duration of 80.6+/- 66.8 months (min 14, max 336, median 72); the evolution to SLE occurred after a mean disease duration of 66.8+/-43.3 months (min 17, max 216, median 57). Anti-cardiolipin antibodies were the only variable correlated with the evolution to SLE (p<0.05). Stable UCTD were characterized by a simplified clinical picture with no major organ involvement and by a simplified autoantibody profile (anti-Ro/SSA antibodies and anti-RNP antibodies were the single antibody specificities observed in 22% and 13% of patients respectively). These results confirm previous data showing that about 30% of UCTD patients will develop a defined CTD, the predictive role of anti-cardiolipin antibodies for the evolution to SLE, and the existence of stable UCTD, distinct clinical entities with a simplified clinico-serological profile. The early identification of stable UCTD is very important both from a clinical and a research point of view. Future research is needed to define a new set of classification criteria.

Abstract: OBJECTIVES: Anti-citrullinated protein/peptide antibodies (ACPA), a family of antibodies with overlapping specificities, represent a specific marker of rheumatoid arthritis (RA). The aim of the present study is to investigate the prevalence and clinical significance of IgG, IgA and IgM ACPA by a newly described assay employing a viral citrullinated peptide (VCP). METHODS: IgG, IgA and IgM anti-VCP antibodies have been measured in sera from 146 patients affected by RA and 404 controls, including 204 chronic arthritides, 111 connective tissue disorders and 89 healthy subjects. The affinity of the different isotypes for VCP was analysed by liquid phase inhibition assays. RESULTS: Among RA patients, 40 were single positive for IgG anti-VCP, five for IgA and 11 for IgM. Ten patients were double positive for IgG and IgA, four for IgG and IgM, six for IgA and IgM. In 15 RA patients IgG, IgA and IgM anti-VCP antibodies were detected. No correlation could be found between the isotype and the clinical manifestations or duration of the disease. IgA anti-VCP were strongly associated with RA, whereas IgM anti-VCP were detected also in a low percentage of systemic lupus erythematosus, psoriatic arthritis and mixed cryoglobulinaemia (MC) patients. IgG anti-VCP displayed a higher affinity for the antigen than IgA or IgM. CONCLUSIONS: These data show that anti-VCP of IgG and IgA isotype discriminate RA from other chronic arthritides and disease controls and suggest an independent production of each isotype.

Abstract: We report on a female case of rheumatoid arthritis (RA) with hepatitis C virus comorbidity. The patient was treated once weekly over ten consecutive weeks with Adacolumn device. Clinical assessment and HCV-RNA concentration were monitored at weeks-1, 4, 9, 14 and during follow-up over 6 months. At the end of the treatment: the number of tender and swollen joints, patient's global assessment of disease activity (VAS), physician's VAS, C-reactive protein (CRP) decreased, respectively; ACR response was >20. This improvement was maintained for over 2 months. At week 38, the patient was re-treated achieving again an ACR response >20.

Abstract: The integrin alpha(v)beta3, whose alpha(v) subunit is encoded by the ITGAV gene, plays a key role in angiogenesis. Hyperangiogenesis is involved in rheumatoid arthritis (RA) and the ITGAV gene is located in 2q31, one of the suggested RA susceptibility loci. Our aim was to test the ITGAV gene for association and linkage to RA in a family-based study from the European Caucasian population. Two single nucleotide polymorphisms were genotyped by PCR-restriction fragment length polymorphism in 100 French Caucasian RA trio families (one RA patient and both parents), 100 other French families and 265 European families available for replication. The genetic analyses for association and linkage were performed using the comparison of allelic frequencies (affected family-based controls), the transmission disequilibrium test, and the genotype relative risk.We observed a significant RA association for the C allele of rs3738919 in the first sample (affected family-based controls, RA index cases 66.5% versus controls 56.7%; P = 0.04). The second sample showed the same trend, and the third sample again showed a significant RA association. When all sets were combined, the association was confirmed (affected family-based controls, RA index cases 64.6% versus controls 58.1%; P = 0.005). The rs3738919-C allele was also linked to RA (transmission disequilibrium test, 56.5% versus 50% of transmission; P = 0.009) and the C-allele-containing genotype was more frequent in RA index cases than in controls (RA index cases 372 versus controls 339; P = 0.002, odds ratio = 1.94, 95% confidence interval = 1.3-2.9). The rs3738919-C allele of the ITGAV gene is associated with RA in the European Caucasian population, suggesting ITGAV as a new minor RA susceptibility gene.
