Abstract
BackgroundCurrently, assessment of dermal thickness in systemic sclerosis (SSc) is performed by palpation and assessment using the modified Rodnan skin score (mRSS).ObjectiveTo verify whether high frequency ultrasound (US) may be a reliable and a reproducible method to measure digital dermal thickness.MethodsIn 70 patients with SSc, skin thickness was evaluated with US by 2 observers at 2 different sites on the second digit of the dominant limb to determine the interobserver variability. Patients and controls were examined twice by the first observer for intraobserver variability. Patients were divided into three subgroups according to the phase of the disease (oedematous, fibrotic or atrophic).ResultsAt both examined areas, US showed a significant dermal thickening (p<0.001) in the whole group of patients with SSc. A low intraobserver and interobserver variability was found. A highly significant correlation between the global mRSS and the local dermal thickness at the two examined sites (p=0.032, p=0.021) was detected. Skin thickness was significantly higher in the oedematous than in the fibrotic group (p<0.001) and significantly higher in the fibrotic and the oedematous group (p<0.001) than in the atrophic group (p<0.002).ConclusionsUS is a reliable tool giving reproducible results, and is able to detect digital dermal thickening in SSc.

Abstract
OBJECTIVE To study the frequency and features of joint and tendon involvement in the hand of patients with primary Sjögren's syndrome (pSS) by musculoskeletal ultrasound (US) examination. METHODS Forty-eight patients with pSS diagnosed according to the preliminary classification criteria proposed by the American-European Classification Criteria Group were enrolled in the study. Bilateral US examination of the 1st-5th metacarpophalangeal (MCP), 2nd-5th proximal interphalangeal (PIP) joints and of flexor tendons were performed. A semi-quantitative grading method (0 to 3) for scoring joint effusion, synovial proliferation and intra-articular power Doppler (PD) signal was used. RESULTS We observed clear evidence of inflammatory arthritis in 9 (18.7%) patients. Bone erosions at MCP and/or PIP joint were visualized in 6 out of 48 (12.5%) patients. In 10 (20.8%) patients we imaged flexor tenosynovitis which appeared more frequent than in healthy subjects even if no statistically significant difference was detected. CONCLUSION US examination appears to be a useful imaging technique to study joint and soft tissue involvement in connective tissue diseases. The presence of bone erosions in pSS patients is unexpected. Future studies will hopefully concentrate more on defining the erosive capability of connective tissue disorders together with inflammatory involvement of tendons.

Abstract
OBJECTIVES To compare health-related quality of life (HRQL) in fibromyalgia (FM) patients with that of patients with rheumatoid arthritis (RA) and the general population, and investigate if the factors are associated with the greater impact of FM. METHODS This cross-sectional study involved 380 patients with FM, 693 patients with RA and 1579 healthy controls. HRQL was evaluated using the Medical Outcome Study Short-Form 36 (SF-36), and the measures included disease-related characteristics, demographic variables and comorbidities. S-scores were calculated for comparisons with the norm, and multivariate analyses were used to assess the relationships between HRQL and clinical and demographic variables. RESULTS In comparison with the general population, the FM patients showed significant impairment in relation to all of the eight scales of the SF-36 (p<0.0001), as well as the physical and mental component summary scores (PCS and MCS) (p<0.0001). The mean PCS and MCS of the FM patients were 38.5 (SD=6.9) and 32.8 (SD=10.9), whereas those of the RA patients were 33.5 (SD=6.4) (p<0.01) and 40.2 (SD=11.9) (p<0.001). The dimensions typically affected by FM were vitality (s-score -1.61), mental health (s-score -1.46) and general health (s-score-1.47), whereas physical functioning (s-score-1.63) and role limitations due to physical function (s -score -0.94) were more impaired in the RA patients; the bodily pain scores were similar in the two groups. The PCS was lower than the MCS in the RA patients (s-scores -1.80 vs. -0.62), but the two scores were similar in the FM patients (s-scores -1.20 vs. -1.08). Multiple regression models showed that the physical component of the SF-36 was associated with widespread pain (the SAPS score) (p<0.0001), educational level (p=0.0017), and the body mass index (p=0.007), and the mental component was associated with the widespread pain (p=0.0005), sleep abnormalities (p=0.0033), physical function (p=0.015), fatigue (p=0.029), gender (p=0.014) and a low educational level (p=0.0007). CONCLUSION Patients with FM see the disease as having a worse health than RA patients and the general population, especially in terms of mental health.

Development and validation of the self-administered Fibromyalgia Assessment Status: a disease-specific composite measure for evaluating treatment effect. Arthritis Res Ther 2009; 11:R125. [PMID: 19686606 PMCID: PMC2745809 DOI: 10.1186/ar2792] [Citation(s) in RCA: 40] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2009] [Revised: 07/15/2009] [Accepted: 08/18/2009] [Indexed: 12/26/2022] Open
Abstract
INTRODUCTION The Fibromyalgia Impact Questionnaire (FIQ) is a composite disease-specific measure validated for fibromyalgia (FM), but it is rarely used in clinical practice. The objective was to develop and analyse the psychometric properties of a new composite disease-specific index (Fibromyalgia Assessment Status, FAS), a simple self-administered index that combines a patient's assessment of fatigue, sleep disturbances and pain evaluated on the basis of the 16 non-articular sites listed on the Self-Assessment Pain Scale (SAPS) in a single measure (range 0 to 10). METHODS The FAS index was constructed using a traditional development strategy, and its psychometric properties were tested in 226 FM patients (209 women, 17 men); whose disease-related characteristics were assessed by means of an 11-numbered circular numerical rating scale (NRS) for pain, fatigue, sleep disturbances and general health (GH), the tender point score (TPS), the SAPS, the FIQ, and the SF-36. A group of 226 rheumatoid arthritis (RA) patients was used for comparative purposes. Of the 179 FM patients who entered the follow-up study, 152 completed the three-month period and were included in the responsiveness analyses. One hundred and fifty-four patients repeated the FAS questionnaire after an interval of one week, and its test/re-test reliability was calculated. Responsiveness was evaluated on the basis of effect size and the standardised response mean. RESULTS The FAS index fulfilled the established criteria for validity, reliability and responsiveness. Factor analysis showed that SAPS and fatigue contributed most, and respectively explained 47.4% and 31.2% of the variance; sleep explained 21.3%. Testing for internal consistency showed that Cronbach's alpha was 0.781, thus indicating a high level of reliability. As expected, closer significant correlations were found when FAS was compared with total FIQ (rho = 0.347; P < 0.0001) and the FIQ subscales, particularly job ability, tiredness, fatigue and pain (all P < 0.0001), but the correlation between FAS and the mental component summary scale score (MCS) of the SF-36 (rho = -0.531; P < 0.0001) was particularly interesting. Test/re-test reliability was satisfactory. The FAS showed the greatest effect size. The magnitude of the responsiveness measures was statistically different between FAS (0.889) and the FIQ (0.781) (P = 0.038), and between the SF-36 MCS (0.434) and the SF-36 physical component summary scale score (PCS) (0.321) (P < 0.01). CONCLUSIONS The self-administered FAS is a reliable, valid and responsive disease-specific composite measure for assessing treatment effect in patients with FM.

Abstract
OBJECTIVE The Disease Activity Score including 28 joints (DAS28) and the Clinical Disease Activity Index (CDAI) were developed in order to provide a quantifiable measure of rheumatoid arthritis (RA) activity. The aim of this study was to evaluate the validity and internal consistency reliability for DAS28 and CDAI in patients with RA seen by rheumatologists in usual clinical care. We also compared proposed categories of high, moderate, and low activity and remission according to both scores. PATIENTS AND METHODS A sample of 2864 RA patients (2267 female, 597 male; mean age 58.5 yr, range 18-88 yr) were enrolled in this cross-sectional community-based study. Disease activity was assessed in each patient based on DAS28 and CDAI. Patients completed the Health Assessment Questionnaire (HAQ). Statistical evaluation was carried out by applying the Cronbach's values and principal component analysis (internal consistency reliability), the Pearson's coefficients, ANOVA and kappa statistic (convergent validity) and receiver operating characteristic (ROC) curve analysis (discriminant validity). RESULTS Internal consistency testing of both scores indicated a reasonable difference, with Cronbach's alpha slightly higher for the DAS28. Interestingly, factor analysis revealed that the DAS28 constitutes a monocomponent measure in RA. Linear regression analysis showed a significant correlation between DAS28 and CDAI (p<0.0001). In addition, the DAS28 and CDAI were well correlated with HAQ (both at p level of <0.0001). The discriminatory power of both indices was good, without significant difference, but our results showed wide differences in both moderate/high disease activity and remission percentages (k=0.418). CONCLUSIONS DAS28 and CDAI are valid and simple acceptable ways to measure RA activity in the clinical practice, but disease activity categorized by these indices differ considerably. Further research is needed to resolve this issue.

Abstract
Three-dimensional (3D) US is a new sonographic modality which represents a promising tool in the assessment of joint and periarticular tissues abnormalities in rheumatic diseases. The available literature has recently underlined its advantages mainly related to the virtual operator independence due to image acquisition of infinite 3D data sets obtained by transducer automated sweeping. Shortening of the US examination time represents another notable advantage over conventional two-dimensional (2D) US. The aim of the present study was to investigate the validity of 3D US in assessing Achilles tendon enthesitis by comparing it with 2D US. US examinations were performed by using a Logiq 9 (General Electrics Medical Systems, Milwaukee, WI) equipment with a high-frequency (8-15 MHz) volumetric probe. One hundred and eighty-six Achilles tendon enthesis of 93 SpA patients were examined. The analysis of each basic US finding demonstrated from good to excellent agreement rates between 3D and 2D US, both in dichotomous assessment of sonographic lesions and in the use of semi-quantitative grading. Excellent agreement between the two modalities was demonstrated in the assessment of both inflammatory changes and structural lesions. Our study for the first time demonstrated that 3D US is a valid imaging modality for the assessment of Achilles tendon enthesitis.

Abstract
OBJECTIVE We have developed a self-taught course by which rheumatologists in training can learn how to conduct capillaroscopy examinations using a computerized videomicroscopy system. We assessed the effectiveness of this course by following the learning curve of one specialist trainee with no experience in capillaroscopy. METHODS The student's training consisted of 10 practical sessions held on three consecutive days. The perceived difficulty in completing each session was graded from 0 (least difficult) to 10 (most difficult). All the images obtained were stored and the time spent by both the trainee and the tutor during the sessions was recorded. Each image was blindly judged by both the novice and the tutor for quality, assigning a score from 0 (lowest quality) to 10 (highest quality). The minimum acceptable score for standard clinical practice was considered to be >5. RESULTS The student spent a total of approximately 5 non-consecutive hours engaged in 'direct' capillaroscopy and recorded a total of 172 images. The mean time required to produce each image varied from approximately 1.0 to 2.0 minutes. The perceived difficulty in completing a session decreased from the first to the last session. A quality score > 5 was assigned by the novice and tutor, respectively, to 16/49 images for the first group of sessions, 26/45 for the second group of sessions, and 56/78 for the third group of sessions. The overall agreement between the novice and tutor was good (K=0.617, SE=0.021). CONCLUSIONS The monitoring of one rheumatologist in training indicates that novices can quickly learn, through an intensive self-teaching programme under the supervision of an expert, how to use computerized videomicroscopy to conduct capillaroscopy studies.

Abstract
Involvement of the sacroiliac joints is the first predominant finding of all seronegative spondylarthropathies (SpA) subsets, such as ankylosing spondylitis, psoriatic arthritis, and undifferentiated SpA. Although conventional radiography is indicated in the initial evaluation of sacroiliac joints diseases, it is often insensitive for demonstrating the early changes of sacroiliitis, so other imaging techniques typically are often necessary to clarify the pathology and for establishing the early diagnosis of seronegative SpA. Other imaging modalities, including computed tomography (CT), magnetic resonance imaging (MRI), ultrasonography (US), and bone scintigraphy have improved visualization of inflammatory changes at the sacroiliac joints (SIJ). CT scans are indicated for disease processes in which bony destruction or ossification may occur. MRI has been proposed as an imaging method to detect sacroiliitis earlier. MRI can identify both inflammation and structural changes caused by inflammation, while radiographs show only structural changes. MRI may be particularly useful in making a diagnosis of SpA. Musculoskeletal US has an increasing and relevant role in the evaluation of SpA mainly for its ability to assess joint and periarticular soft tissue involvement and in particular for its capacity to detect enthesitis. US assessment in general is safe, noninvasive, and comparably cheap, showing itself as a complimentary tool to clinical evaluation in SpA; nevertheless, it is very user dependent. Bone scintigraphy is at most of limited diagnostic value for the diagnosis of established AS, including the early diagnosis of probable/suspected sacroiliitis. The main aim of this study is to introduce the clinical and radiological aspects of the SIJ involvement in SpA, particularly the contribution of the different imaging techniques.

Abstract
Drug Hypersensitivity Syndrome, also known as Drug Rash with Eosinophilia and Systemic Symptoms is a severe adverse reaction characterized by clinical manifestations including fever, skin eruption, lymphoadenopathy, associated with eosinophilia, leukocytosis and multiple visceral involvement, with 10% of mortality due to development of multiple organ failure. This reaction usually occurs between two and six-eight weeks after the beginning of the treatment and may not resolve with interruption of the suspected drug. Sulfonamides, anticonvulsant, allopurinol are the most frequently involved molecules, but recently cases have been described also with gabapentin and strontium ranelate. In the present report we describe a case of a patient with rheumatoid arthritis who presented severe drug hypersensitivity syndrome, with liver and kidney involvement due to sulphasalazine.

Abstract
OBJECTIVES To determine clinical and ultrasonographic predictors of joint replacement surgery across Europe in primary osteoarthritis (OA) of the knee. METHODS This was a 3-year prospective study of a painful OA knee cohort (from a EULAR-sponsored, multicentre study). All subjects had clinical evaluation, radiographs and ultrasonography (US) at study entry. The rate of knee replacement surgery over the 3-year follow-up period was determined using Kaplan-Meier survival data analyses. Predictive factors for joint replacement were identified by univariate log-rank test then multivariate analysis using a Cox proportional-hazards regression model. Potential baseline predictors included demographic, clinical, radiographic and US features. RESULTS Of the 600 original patients, 531 (88.5%), mean age 67+/-10 years, mean disease duration 6.1+/-6.9 years, had follow-up data and were analysed. During follow-up (median 3 years; range 0-4 years), knee replacement was done or required for 94 patients (estimated event rate of 17.7%). In the multivariate analysis, predictors of joint replacement were as follows: Kellgren and Lawrence radiographic grade (grade > or =III vs <III, hazards ratio (HR) = 4.08 (95% CI 2.34 to 7.12), p<0.0001); ultrasonographic knee effusion (> or =4 mm vs <4 mm) (HR = 2.63 (95% CI 1.70 to 4.06), p<0.0001); knee pain intensity on a 0-100 mm visual analogue scale (> or =60 vs <60) (HR = 1.81 (95% CI 1.15 to 2.83), p=0.01) and disease duration (> or =5 years vs <5 years) (HR=1.63 (95% CI 1.08 to 2.47), p=0.02). Clinically detected effusion and US synovitis were not associated with joint replacement in the univariate analysis. CONCLUSION Longitudinal evaluation of this OA cohort demonstrated significant progression to joint replacement. In addition to severity of radiographic damage and pain, US-detected effusion was a predictor of subsequent joint replacement.

Abstract
OBJECTIVE To retrospectively evaluate the role of the various imaging techniques in the study of the sternocostoclavicular joint, in patients with spondyloarthropathies and other rheumatic conditions and to assess potential pitfalls in the radiological diagnosis. SUBJECTS AND METHODS Thirty patients, 11 male and 19 female, mean age 45 years, with involvement of the sternocostoclavicular joint as part of rheumatologic disorders (psoriatic arthritis, ankylosing spondylitis, Tietze syndrome, SAPHO syndrome, and condensing osteitis of the clavicle) were studied. Conventional radiography, CT, MRI and bone scintigraphy were performed. The following imaging findings were evaluated: soft tissue swelling, bone sclerosis, cortical bone erosions, joint space narrowing, subchondral sclerosis, periosteal new bone formation, synovial reaction and intrarticular effusion. All the images were independently reviewed by two musculoskeletal radiologists. RESULTS Conventional radiography demonstrated only sclerosis of the clavicula in 8 pts (26%) and the sternum in 3 pts (10%), cortical bone erosions in 7 pts (23%), joint space narrowing in 6 pts (23%) and periosteal bone formation in 2 pts (10%). At the CT examination sclerosis of the clavicula and the sternum was observed in 13 pts (44%), cortical bone erosions in 22 pts (76%), joint space narrowing in 10 pts (34%), ligament ossification in 12 pts (41%), subchondral sclerosis in 9 pts (34%) and periosteal bone formation in 10 pts (34%). The MRI was the most sensitive technique in the evaluation of the soft tissue swelling in 9 pts (56%), intrarticular effusion in 13 pts (81%) and synovial reaction in 13 pts (81%). Finally, bone scintigraphy showed an increased uptake at the sterno-costoclavicular joint in all patients who underwent the examination. CONCLUSION The radiological evaluation of the anterior chest wall in patients with different rheumatic disorders represents a problem of difficult diagnostic evaluation both for the anatomic region complexity and for the variability of the radiographic findings. The integrated use of X-ray, CT, MRI and nuclear medicine is suggested to avoid misdiagnosis.

Abstract
Identification of early indicators of diagnosis and prognosis together with tight control of disease activity are the current goals of management of early arthritis. Several studies in the literature to date suggest that musculoskeletal ultrasonography (US) may have a role in this setting. US is a valid and reliable tool for the assessment of inflammatory arthritis - either as an ultra-sensitive measure of inflammation or joint damage. US is also useful in the differential diagnosis of early arthritis, both identifying disease specific findings and integrating clinical findings into structured diagnostic algorithms. Grey scale and power Doppler US are sensitive disease activity and severity markers, identifying subgroups of patients with poorer clinical and radiological outcomes, even once clinical remission has been achieved. The present review provides an update of the available data and discusses research issues of ultrasound imaging in early arthritis.

Abstract
OBJECTIVES To investigate the acceptability, feasibility, reliability and score agreement of collecting rheumatoid arthritis (RA) patient-reported outcome (PRO) data using an interactive touch-screen computer system. METHODS Eighty-seven RA patients completed both the touch-screen and conventional paper-administered set of questionnaires. For this purpose, we have developed a computerized touch-screen system, namely RHEUMATISM (RHEUMA Touch-screen Italian SysteM), to capture PRO data. Variables recorded include the following information: demographic data, VAS scores for pain, patient's and physician's assessment of global activity, and physician's assessment of general health status, 28-joint counts measuring tender and swollen joint, patient self-reported tender joint count, Recent-Onset Arthritis Disability index, and laboratory findings. In a further test-retest study, 35 patients were evaluated. RESULTS Although over half the patients had no prior computer experience, nearly all found the touch-screen easy to use. Moreover, 86% of the patients preferred the computer format to the paper format (2%) and 12% of subjects had no preference. The quality of the data collected with the touch-screen system was good, with no missed responses. Agreement between scores obtained with the two modes of administration was very good, with concordance correlation coefficients (CCCs) from 0.887 to 0.972. CCCs were similar in men and in women, in subjects with or without prior computer experience and in subjects below or above age 65. The electronic questionnaire had good test-retest reliability (CCCs from 0.836 to 0.907). CONCLUSIONS Computer touch-screen questionnaires were well accepted by RA patients, with good data quality, reliability and score agreement.

Abstract
Background The health-related quality of life (HRQL) is an important indicator of the burden of musculoskeletal disease. The Medical Outcome Study Short-Term 36 (SF-36) is the most used tool that evaluates HRQL as a subjective perception about psychological and physical limitations due to an underlying illness. The purpose of this study was to compare the HRQL scores among patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA) and ankylosing spondylitis (AS) and a selected sample of health people and determine their relationship with measures of clinical condition. Methods 799 patients (469 with RA, 164 with AS, 65 with axial PsA and 101 with peripheral PsA) accepted the invitation to participate. 1579 healthy controls were used for the comparison. We calculated scores for the eight SF-36 subscales, the Physical Component Summary (PCS) score, and the Mental Component Summary (MCS) score, according to published algorithms. Disease-related characteristics included disease duration, comorbidity, a measure for disease activity and for radiographic damage. The presence of comorbidity was ascertained through patient's self-reports by the Self-Administered Comorbidity Questionnaire (SCQ). Comparison were performed with respect to sex and age, and s-scores were calculated for comparison with the norm. Multivariate analyses were used to assess the relationship between HRQL and radiographic damage, disease activity, and socio-demographic data. Results The four inflammatory rheumatic diseases (IRD), compared to controls, significantly impaired all eight health concepts of the SF-36 (p < 0.0001) in both component PCS and MCS scores (p < 0.0001). Overall, the dimensions typically affected were physical functioning, limitations due to physical function, and bodily pain. The disease with the worst HRQL for those dimensions was RA. The multivariate analyses revealed that the physical component was influenced by a high disease activity and comorbidity. The severity of psoriatic lesions was associated with poor mental functioning in patients with PsA. Conclusion Chronic IRD have a clearly detrimental effect on the HRQL in both sex and in age groups, and physical domain is more impaired than mental and social ones.

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
OBJECTIVE The main aim of the present study was to determine the sensitivity, specificity and accuracy of ultrasonography (US) in detecting monosodium urate and calcium pyrophosphate dihydrate crystals deposits at knee cartilage level using clinical definite diagnosis as standard reference. DESIGN A total of 32 patients with a diagnosis of gout and 48 patients with pyrophosphate arthropathy were included in the study. Fifty-two patients with rheumatoid arthritis (RA), psoriatic arthritis or osteoarthritis (OA) were recruited as disease controls. All diagnoses were made using an international clinical criterion. US examinations were performed by an experienced sonographer, blind to clinical and laboratory data. Hyaline cartilage was assessed to detect two US findings recently indicated as indicative of crystal deposits: hyperechoic enhancement of the superficial margin of the hyaline cartilage and hyperechoic spots within the cartilage layer not generating a posterior acoustic shadow. RESULTS Hyperechoic enhancement of the chondrosynovial margin was found in at least one knee of 14 out of 32 (43.7%) patients with gout and in a single knee of only one patient affected by pyrophosphate arthropathy (specificity=99%). Intra-cartilaginous hyperechoic spots were detected in at least one knee of 33 out of 48 (68.7%) patients with pyrophosphate arthropathy and in two disease controls one with OA and the second with RA (specificity=97.6%). CONCLUSIONS The results of the present study indicate that US may play a relevant role in distinguishing cartilage involvement in patients with crystal-related arthropathy. The selected US findings were found to be highly specific.

Abstract
Objectives: To assess the efficacy and safety of abatacept in methotrexate-naive patients with early rheumatoid arthritis (RA) and poor prognostic factors. Methods: In this double-blind, phase IIIb study, patients with RA for 2 years or less were randomly assigned 1 : 1 to receive abatacept (∼10 mg/kg) plus methotrexate, or placebo plus methotrexate. Patients were methotrexate-naive and seropositive for rheumatoid factor (RF), anti-cyclic citrullinated protein (CCP) type 2 or both and had radiographic evidence of joint erosions. The co-primary endpoints were the proportion of patients achieving disease activity score in 28 joints (DAS28)-defined remission (C-reactive protein) and joint damage progression (Genant-modified Sharp total score; TS) at year 1. Safety was monitored throughout. Results: At baseline, patients had a mean DAS28 of 6.3, a mean TS of 7.1 and mean disease duration of 6.5 months; 96.5% and 89.0% of patients were RF or anti-CCP2 seropositive, respectively. At year 1, a significantly greater proportion of abatacept plus methotrexate-treated patients achieved remission (41.4% vs 23.3%; p<0.001) and there was significantly less radiographic progression (mean change in TS 0.63 vs 1.06; p = 0.040) versus methotrexate alone. Over 1 year, the frequency of adverse events (84.8% vs 83.4%), serious adverse events (7.8% vs 7.9%), serious infections (2.0% vs 2.0%), autoimmune disorders (2.3% vs 2.0%) and malignancies (0.4% vs 0%) was comparable for abatacept plus methotrexate versus methotrexate alone. Conclusions: In a methotrexate-naive population with early RA and poor prognostic factors, the combination of abatacept and methotrexate provided significantly better clinical and radiographic efficacy compared with methotrexate alone and had a comparable, favourable safety profile.

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
OBJECTIVE To investigate the association between articular chondrocalcinosis and calcification of the atlantoaxial region on a cervical computed tomography (CT) scan and to explore the relation between such calcifications and neck pain. MATERIALS AND METHODS CT slices of the cervico-occipital junction were performed routinely in 49 consecutive patients (male/female ratio 28/21; mean age 70.4 yrs), diagnosed with calcium pyrophosphate dihydrate crystal deposition disease (CPPD). Of these, 35 met criteria for definite CPPD and 14 met the criteria for probable. The cervical CT scans were analyzed for the presence of periodontoid calcifications by 2 independent musculoskeletal radiologists. Both assessors were blinded to the disease status of the patients. Furthermore, conventional radiographs of the upper cervical spine were performed. An ad hoc designed protocol was used to register information at diagnosis, including age, sex, location of pain and stiffness, fever, presence of synovitis and its location. RESULTS CT scan of the cervico-occipital junction showed periodontoid calcified deposits in 25 out of 49 patients (51%) with CPPD. In 10 of the 25 cases (40%) with periodontoid calcified deposits, CT scanning showed osseous abnormalities of the odontoid process, such as subchondral cysts or erosions. Conventional radiographs showed calcification behind the odontoid process in 17 patients (34.7%). Nine of CPPD cases (18.4%) presented with neck symptoms. In three patients, articular chondrocalcinosis was revealed only by an acute attack of neck pain with segmentary stiffness, fever, and an increased erythrocyte sedimentation rate; in one of them initial clinical examination found cervical stiffness with Kernig's and/or Brudzinski's sign. For the other two patients, impairment of general condition, occipito-temporal and mandible pain and weakness with inflammatory pain of the shoulder girdle was suggestive of giant cell arteritis (GCA) and/or polymyalgia rheumatica (PMR). In the six additional patients, questioning elicited a history of previous subacute or chronic neck pain, from one week to one year before their admission to our ambulatory or hospital. CONCLUSIONS These results suggest that CPPD deposition disease frequently involves the cervical spine. Although such calcification often remains asymptomatic, it may be associated with attacks of acute neck pain with segmentary stiffness, fever, and an increased erythrocyte sedimentation rate, sometimes mimicking PMR and/or GCA or neurological symptoms.

Abstract
Over the last few years, a growing number of rheumatologists has taken great interest in ultrasonography for its well known advantages and wide spectrum of validated applications in daily rheumatological practice. Most rheumatologists actively performing ultrasonography have had a training experience mainly based on attendance in sonographic courses and/or in radiological or rheumatological units. At present, in Mexico ultrasonography has a still limited diffusion among rheumatologists even if it may play a key role as a first line imaging technique also because of the restricted availability for rheumatic patients for other imaging modalities. This report describes the Mexican experience in education and training on musculoskeletal ultrasound. In 2003, the Mexican School of Musculoskeletal Ultrasound of the Mexican College of Rheumatology (ECOMER) was founded with the intention of joining efforts to launch musculoskeletal ultrasound in Mexico. Essential requirements shared by all the members of ECOMER include: to own an ultrasound machine, to incorporate ultrasonography into clinical daily practice and to keep up-to-date in musculoskeletal ultrasound. The motto of ECOMER is una clara imagen de la reumatologia which means a clear picture of rheumatology. The statute of ECOMER can be read in its web site: www.ecomer.org.mx. This web site also provides a forum for case discussion, consultation and image review.

Abstract
The use of Doppler ultrasound in rheumatology has grown in recent years. This is partly due to the increasing number of rheumatologists who perform US in their daily clinical practise and also to the technological advances of US systems. Both colour Doppler and power Doppler are used to evaluate the degree of intra- and peri-articular soft tissue inflammation. Moreover, Doppler US has been found to be of help in the assessment of vascular pathologies such as the vasculitides. In this review we provide an update of the data regarding the use of colour Doppler and power Doppler in rheumatology.

Abstract
Sjögren's syndrome (SS) is a chronic inflammatory disease with an autoimmune etiology, that affects exocrine glands, in particular salivary and lacrimal glands. Among the diagnostic criteria of SS, imaging techniques play an important role. The aim of our study is to compare three imaging techniques, such as sonography, scintigraphy and sialography in the evaluation of major salivary glands. The use of the these techniques is of great importance for the diagnosis of SS. Sonography is the most frequently used for its prompt execution, non invasivity, great acceptance by the patient and low cost. In the diagnostic patient management of SS, sonography results are eventually confirmed by the other imaging techniques, sialography and scintigraphy.

Abstract
Ultrasonography (US) has proved to be a useful tool for the clinical evaluation of patients with rheumatic diseases. It is also recognised as a useful imaging technique in interventional radiology. In the last few years, a number of rheumatologists have also described and advocated the use of US guidance in joint and soft tissue aspiration and injection technique in clinical practice. Moreover, US-guided synovial biopsy methods have been proposed as an interesting and reliable method for the histopathological assessment of small and large joint sinovium. The present review provides an update of the available data regarding the use of US in interventional procedures in clinical rheumatology.

Abstract
Over the last few years, a large number of studies have emphasized the fundamental role of ultrasonography (US) in the clinical evaluation of patients affected by rheumatic disorders. However, not all rheumatic diseases have been studied by US. To date, very few reports exist on the use of US in the assessment of articular, periarticular structures and blood vessels in vasculitis. In this review we provide an overview of the current data regarding the role of US in vasculitis. Sonographic evaluation of cardiac or renal involvement in these disorders will not be covered.

Abstract
Ultrasound (US) role is becoming more and more relevant in the assessment of rheumatic diseases but there are still some almost unexplored fields and, surely, one of these is represented by the great family of connective tissue diseases (CTD). In this review we provide an update of the available data regarding some applications of US in CTD. Besides an overview of the role of US in their musculoskeletal involvement, we will report data on the use of US in the evaluation of skin and lung in systemic sclerosis and of salivary glands in Sjögren's syndrome. US assessment of heart, kidney or vascular involvement in CTD will not be the subjects of this paper.

Abstract
OBJECTIVE To evaluate by clinical, laboratory, and sonographic assessment the effects of adalimumab therapy in patients with rheumatoid arthritis (RA) over 24 months of treatment. METHODS Twenty-five patients with RA were commenced on adalimumab therapy. Before the beginning of the therapy (Time 0) and after 3 (T1), 12 (T2), and 24 (T3) months we evaluated erythrocyte sedimentation rate, C-reactive protein, physician and patient visual analog scale for disease activity, number of tender and swollen joints, Health Assessment Questionnaire, and Disease Activity Score in 28 joints. In addition, musculoskeletal ultrasound (US) was performed bilaterally in the 2nd and 5th metacarpophalangeal, 3rd interphalangeal, wrist, and knee joints and in the tendon sheaths and bursae of those areas. A semiquantitative score (0 3) was used to indicate the presence of a localized inflammatory process and/or structural damage. The summed total was used as an indicator of global change in each joint (single joint score). The sum of the single joint scores was used as an indicator of overall polyarticular involvement in each patient (total score). RESULTS Patients who did not submit to the planned examinations strictly on time were excluded from the study. Then 25 patients were examined at T0 and T1, 20 at T2, and 9 at T3. All clinical and laboratory measures as well as the US scores were significantly reduced during the followup. CONCLUSION A positive response to treatment with adalimumab was demonstrated by clinical, laboratory, and US evaluation by both short- and longterm followup.

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
The present review discusses the most frequent sport-related conditions which can present to rheumatologists and the available evidence base for using ultrasonography (US) in such scenarios. From a rheumatological perspective, sports-related pathology is mainly characterised by sub-acute and chronic overuse and stress-related disorders involving tendons, ligaments, muscles, joints and entheses. Major acute injuries are less frequently assessed in a standard rheumatological setting.Longitudinal studies are required to determine the clinical importance of US findings in athletes, particularly those who are asymptomatic. US findings need to be correlated with standard references including surgical and magnetic resonance imaging assessments. Future research should also be directed at determining the usefulness of power Doppler technique in monitoring sport-related abnormalities.

Abstract
OBJECTIVE To develop education guidelines for the conduct of future European League Against Rheumatism (EULAR) musculoskeletal ultrasound (MSUS) courses. METHODS We undertook a consensus-based, iterative process using two consecutive questionnaires sent to 29 senior ultrasonographer rheumatologists who comprised the faculty of the 14th EULAR ultrasound course (June 2007). The first questionnaire encompassed the following issues: type of MSUS educational model; course timing; course curriculum; course duration; number of participants per teacher in practical sessions; time spent on hands-on sessions; and the requirements and/or restrictions for attendance at the courses. The second questionnaire consisted of questions related to areas where consensus had not been achieved in the first questionnaire, and to the topics and pathologies to be assigned to different educational levels. RESULTS The response rate was 82.7% from the first questionnaire and 87.5% from the second questionnaire. The respondents were from 11 European countries. The group consensus on guidelines and curriculum was for a three-level education model (basic, intermediate and advanced) with timing and location related to the annual EULAR Congresses. The topics and pathologies to be included in each course were agreed. The course duration will be 20 h. There will be a maximum of six participants per teacher and 50-60% of total time will be spent on practical sessions. There was also agreement on prerequisite experience before attending the intermediate and advanced courses. CONCLUSION We have developed European agreed guidelines for the content and conduct of EULAR ultrasound courses, which may also be recommended to national and local MSUS training programmes.

Abstract
Joint fluid aspiration, or arthrocentesis, is one of the most useful and commonly performed procedures for the diagnosis and treatment of rheumatic diseases, but to date no definite guidelines have been published. For this reason, a group of experts of the Italian Society of Rheumatology (SIR) produced evidence based recommendations for performing arthrocentesis. Among them, the most relevant are: a) arthrocentesis is necessary when synovial effusion of unknown origin is present, especially if septic or crystal arthritis is suspected; b) the patient should be clearly informed of the benefits and risks of the procedure in order to give an informed consent; c) ultrasonography should be used to facilitate arthrocentesis in difficult joints; d) fluid evacuation often has a therapeutic effect and facilitates the success of the following intraarticular injection; e) careful skin disinfection and the use of sterile, disposable material is mandatory for avoiding septic complications. Disposable, non sterile gloves should always be used by the operator, mainly for his own protection; f) contraindications are the presence of skin lesions or infections in the area of the puncture; g) the patient's anticoagulant treatment is not a contraindication, providing the therapeutic range is not exceeded; h) joint rest after arthrocentesis is not indicated. Several of these recommendations were based on experts' opinion rather than on published evidence which is scanty.

Abstract
Regional pain syndromes (RPS) are common complaints in clinical rheumatological practice. Ultrasound (US) allows a detailed assessment of soft tissue involvement and its use may have considerable impact on the management of RPS. The present review provides an update of the available data about US imaging in RPS together with research issues relating to periarticular soft tissue pathology. The research agenda covers: definition of standard scanning protocols for US examination of the most common RPS assessed by the rheumatologist and the clinical impact of US findings in the management of patients with RPS.

Abstract
OBJECTIVE To assess the prevalence of good clinical response and remission in rheumatoid arthritis (RA) patients with longstanding disease treated with anti-tumor necrosis factor-alpha (TNF-alpha) drugs at outpatient clinics. METHODS Retrospective national study of 14 academic tertiary referral rheumatology medical centers. RA patients with a Disease Activity Score (DAS28) > 3.2 were defined as having active disease and could start TNF-alpha blockers. All patients received one TNF-alpha blocker plus methotrexate (10-20 mg/wk). At the third month the patients were categorized as responders or nonresponders, based on improvement of at least 0.25 of the Health Assessment Questionnaire (HAQ). Those who had improved by at least 0.25 HAQ were analyzed for possible predictors of DAS28 remission at the sixth month. RESULTS A total of 1257 patients started TNF-alpha blockers. Of these, 591 (46.7%) reached the sixth month with an improvement of HAQ of 0.25 at the third month. In the cohort of patients reaching HAQ of 0.25, DAS28 remission was seen in 24% of rheumatoid factor (RF)-positive and 36% of RF-negative patients (p = 0.03). Logistic regression analysis for predictors of remission identified age at baseline, HAQ < 1.63, and RF negativity as positive predictors of remission at 6 months along with sex (male). CONCLUSION We show that only a minority of patients with longstanding RA achieve a good clinical response or remission at the outpatient community level. Predictors of remission identify characteristics commonly observed in subsets with less severe RA.

Abstract
Capillaroscopy is an essential imaging technique used in the study of microcirculation and one of the best diagnostic tools for the early detection of systemic sclerosis and related conditions. However, despite the increasing interest in capillary microscopy, there is still a surprising discrepancy between its potential application and its still limited use in rheumatological practice. This contrast is really surprising because few diagnostic techniques can combine all the positive features typical of capillaroscopy (low cost, uninvasiveness, repeatability, high sensitivity, good specificity, easy interpretation of results). The lack of guidelines and recommendations concerning the right way to carry out a correct capillaroscopic examination and the interpretation of the most relevant capillaroscopic abnormalities may represent one of the major drawbacks for its widespread use. Discussion about controversies on this topic should be encouraged, leading to a progressive development of capillaroscopy as a routine investigation in rheumatology.

Abstract
BACKGROUND Patients with rheumatoid arthritis (RA) have a reduced life expectancy and high cardiovascular morbidity and mortality as compared to the general population. A number of possible factors for the atherogenesis in this disease have been described, such as homocysteine, altered serum levels of selected lipoproteins and treatment. Recent findings indicate that the systemic inflammation may contribute to the development of atherosclerosis and confer an additional risk for cardiovascular death among patients with RA. The aim of our study was to evaluate the ability of high resolution Bmode ultrasound and color Doppler to assess the existence of subclinical atherosclerosis in RA patients, measuring the intima-media thickness (IMT) and resistance index of the common carotid arteries. METHODS Carotid IMT and carotid plaque were measured using high-resolution B-mode ultrasound in 40 patients with RA and 40 age- and sex-matched healthy persons. We used color Doppler ultrasound to assess vascular damage of the common carotid arteries and the resistance index (RI) was determined by analysis of the spectral waveforms. Serum total cholesterol, triglycerides-density lipoprotein cholesterol, low-density lipoprotein cholesterol, rheumatoid factor, body mass index (BMI), visual analogue scale (VAS) were determined in patients and controls. C-reactive protein (CRP) and the DAS28 were used to measure systemic inflammation. RESULTS Common carotid IMT were significantly higher (p=0.0009) in RA patients (0.83 +/- 0.23) compared with controls (0.66 +/- 0.22). In RA patients common carotid IMT was significantly correlated with serum total cholesterol (p=0.0008), low-density lipoprotein cholesterol (p=0.006), triglycerides (p=0.042), age (p=0.031) and disease duration (p=0.019). No significant correlation was found with clinical and laboratory parameters reflecting disease activity. The prevalence of plaques was higher in RA patients compared with controls (25% vs 12.5%). There was no significant difference in color Doppler findings, and in particular in RI, between patients and controls. CONCLUSIONS Our results confirm an accelerated atherosclerosis, as shown by increased common carotid IMT, in patients with RA compared with controls and it is related mainly to lipid levels. High-resolution B-mode ultrasound may be considered a promising, sensitive and non invasive tool for assessing the existence of subclinical atherosclerosis in RA patients.

Abstract
OBJECTIVE Vertebral fractures are a common complication of osteoporosis and may have a negative effect on health-related quality of life (HRQOL). We investigated the effect of prevalent vertebral fractures on HRQOL in patients with osteoporosis. METHODS A cross-sectional multicenter study was carried out among postmenopausal women with primary osteoporosis attending primary care centers and hospital outpatient clinics: 234 women with vertebral fractures and 244 asymptomatic women. Women with secondary osteoporosis or taking medications that affect bone metabolism were excluded. All patients were questioned using the mini-Osteoporosis Quality of Life Questionnaire (mini-OQLQ), Medical Outcomes Study Short Form-36 (SF-36), and the EuroQuol-5D, after assessment of all clinical variables and anthropometric data. To assess comorbidity we used the Self-Administered Comorbidity Questionnaire (SCQ). Diagnosis of osteoporosis was confirmed in all patients by bone mineral density using dual energy x-ray absorptiometry. Radiographic evaluation was performed by a musculoskeletal radiologist. A total of 483 postmenopausal women, randomly matched for age out of 1579 healthy controls, were chosen to compare the SF-36 scores with respect to patients with and without vertebral fractures due to osteoporosis. A multivariable regression analysis was conducted to identify the strongest determinant for low HRQOL, adjusted for potential confounding variables such as comorbid conditions, education level, and psychosocial status. RESULTS The vertebral fracture group had significantly lower scores than patients without fractures and controls in all domains of the generic and specific questionnaires. Women with only 1 prevalent fracture had statistically significantly lower HRQOL scores than those without fractures on SF-36 measures of bodily pain, physical functioning, and role function physical (all p < 0.01). HRQOL scores were lower in women with lumbar fractures compared with women with thoracic fractures only when the physical functioning and bodily pain dimensions approached statistical significance. Based on the multivariate analysis, the strongest determinant for low HRQOL was physical functioning (explained by number of vertebral fractures) followed by comorbidity score and age. Adjusted R2 in the final model was 35.9%. Using the SF-36 summary scales, comorbid conditions predominantly affected either mental or physical health (p < 0.0001). A significant correlation (p <0.0001) was found between total score on the mini-OQLQ and the mean SCQ comorbidity score. CONCLUSION Our results confirm previous findings that HRQOL, assessed by generic and osteoporosis-specific instruments, is decreased in patients with vertebral fractures due to osteoporosis as a function of the number of vertebral fractures, presence of comorbid conditions, and age.

Abstract
This review aims to provide an update of the currently available data regarding ultrasound (US) imaging in crystal-related arthropathies (CA). US imaging allows the assessment of patients with CA showing synovitis, bone erosions, tendon, bursal and cartilage pathology. Moreover, the conformation and anatomical location of crystals may help distinguish the different clinical entities, improving the accuracy of diagnosis and sensitivity of disease activity and therapy monitoring. Future topics for study include: consensus on scanning protocols and scoring systems, evaluation of greyscale and power Doppler US in the therapy monitoring of gout and evaluation of the role of 3D US in CA.
