Abstract
Microvascular structure and hemodynamics are important indicators for the diagnosis and assessment of many diseases and pathologies. The structural and functional imaging of tissue microvasculature in vivo is a clinically significant objective for the development of many imaging modalities. Contrast-enhanced ultrasound (CEUS) is a popular clinical tool for characterizing tissue microvasculature, due to the moderate cost, wide accessibility, and absence of ionizing radiation of ultrasound. However, in practice, it remains challenging to demonstrate microvasculature using CEUS, due to the resolution limit of conventional ultrasound imaging. In addition, the quantification of tissue perfusion by CEUS remains hindered by high operator-dependency and poor reproducibility. Inspired by super-resolution optical microscopy, super-resolution ultrasound localization microscopy (ULM) was recently developed. ULM uses the same ultrasound contrast agent (i.e. microbubbles) in CEUS. However, different from CEUS, ULM uses the location of the microbubbles to construct images, instead of using the backscattering intensity of microbubbles. Hence, ULM overcomes the classic compromise between imaging resolution and penetration, allowing for the visualization of capillary-scale microvasculature deep within tissues. To date, many in vivo ULM results have been reported, including both animal (kidney, brain, spinal cord, xenografted tumor, and ear) and human studies (prostate, tibialis anterior muscle, and breast cancer tumors). Furthermore, a variety of useful biomarkers have been derived from using ULM for different preclinical and clinical applications. Due to the high spatial resolution and accurate blood flow speed estimation (approximately 1 mm/s to several cm/s), ULM presents as an enticing alternative to CEUS for characterizing tissue microvasculature in vivo. This review summarizes the principles and present applications of CEUS and ULM, and discusses areas where ULM can potentially provide a better alternative to CEUS in clinical practice and areas where ULM may not be a better alternative. The objective of the study is to provide clinicians with an up-to-date review of ULM technology, and a practical guide for implementing ULM in clinical research and practice.

Abstract
BACKGROUND To evaluate the effect of treatment on serum bone biomarkers and explore whether serum bone biomarkers are associated with therapeutic response in rheumatoid arthritis (RA) patients treated with abatacept. METHODS We enrolled 59 RA patients treated with abatacept from a multicenter, exploratory, short-term, prospective and observational ultrasound cohort study of patients who received biologic or targeted synthetic disease-modifying antirheumatic drug (DMARD) therapy. We evaluated the patients' clinical disease activity and musculoskeletal ultrasound (MSUS) scores. The serum concentrations of five bone biomarkers were evaluated (dickkopf-1 [Dkk-1], sclerostin [SOST], osteocalcin [OC], osteopontin [OPN], and osteoprotegerin [OPG]) by multiplex bead assays at baseline, 3, and 6 months: the change over 6 months was defined as the Δ value. 'Power Doppler (PD) responder' was defined as a patient whose Δtotal PD score over 6 months was greater than the median change. RESULTS Abatacept significantly improved the clinical disease activity and MSUS score over 6 months. Serum OPG was significantly elevated at 6 months after the abatacept introduction (p = 0.016). The ΔSOST and ΔOPG were significantly greater in the PD responders versus the non-PD responders (p = 0.0041 and 0.0073, respectively). The serum Dkk-1 at baseline was significantly lower in the PD responders (n = 30) vs. the non-PD responders (n = 29) (p = 0.026). A multivariate logistic regression analysis showed that the serum Dkk-1 at baseline (odds ratio 0.50, 95% confidence interval [CI] 0.23-0.91, p = 0.043) was an independent predictor of PD responder status. CONCLUSION Serum levels of bone biomarkers may be useful for predicting RA patients' therapeutic responses to abatacept.

Abstract
Background Autoimmune diseases (ADs) are characterized by immune-mediated tissue damage, in which angiogenesis is a prominent pathogenic mechanism. Vascular endothelial growth factor (VEGF), an angiogenesis modulator, is significantly elevated in several ADs including rheumatoid arthritis (RA), systemic sclerosis (SSc), and systemic lupus erythematosus (SLE). We determined whether circulating VEGF levels were associated with ADs based on pooled evidence. Methods The analyses included 165 studies from the PubMed, EMBASE, Cochrane Library, and Web of Science databases and fulfilled the study criteria. Comparisons of circulating VEGF levels between patients with ADs and healthy controls were performed by determining pooled standard mean differences (SMDs) with 95% confidence intervals (CIs) in a random-effect model using STATA 16.0. Subgroup, sensitivity, and meta-regression analyses were performed to determine heterogeneity and to test robustness. Results Compared with healthy subjects, circulating VEGF levels were significantly higher in patients with SLE (SMD 0.84, 95% CI 0.25-1.44, P = 0.0056), RA (SMD 1.48, 95% CI 0.82-2.15, P <0.0001), SSc (SMD 0.56, 95% CI 0.36-0.75, P <0.0001), Behcet's disease (SMD 1.65, 95% CI 0.88-2.41, P <0.0001), Kawasaki disease (SMD 2.41, 95% CI 0.10-4.72, P = 0.0406), ankylosing spondylitis (SMD 0.78, 95% CI 0.23-1.33, P = 0.0052), inflammatory bowel disease (SMD 0.57, 95% CI 0.43-0.71, P <0.0001), psoriasis (SMD 0.98, 95% CI 0.62-1.34, P <0.0001), and Graves' disease (SMD 0.69, 95% CI 0.20-1.19, P = 0.0056). Circulating VEGF levels correlated with disease activity and hematological parameters in ADs. Conclusion Circulating VEGF levels were associated with ADs and could predict disease manifestations, severity and activity in patients with ADs.

Abstract
The Wnt signaling pathway plays a key role in several biological processes, such as cellular proliferation and tissue regeneration, and its dysregulation is involved in the pathogenesis of many autoimmune diseases. Several evidences support its role especially in bone complications of rheumatic diseases. In Rheumatoid Arthritis (RA), the Wnt signaling is implicated in systemic and localized bone loss, while available data of its role in Spondyloarthritis (SpA) are conflicting. In the last few decades, the quality of life of rheumatic patients has been dramatically improved by biological therapy, targeting cytokines involved in the pathogenesis of these diseases like tumor necrosis factor (TNF)α, interleukin (IL)-1, IL-6, IL-17. In this review, we reviewed the role of Wnt signaling in RA and SpA, focusing on the effect of biological therapy on this pathway and its possible clinical implications.

Abstract
OBJECTIVES To study the correlation between high-frequency ultrasonography of patients with early rheumatoid arthritis (RA) and anti-cyclic citrullinated peptide (CCP) antibody. METHODS Two wrists, 1st to 5th metacarpal phalangeal (MCP) and 1st to 5th proximal interphalangeal (PIP) joints of 53 early RA patients treated from October 2015 to October 2017 and 30 healthy subjects were examined by high-frequency ultrasonography. The thicknesses of synovial membrane, sheaths of 1st to 5th extensor tendons, flexor tendons and ulnar wrist extensor tendons were measured. Related pathological changes were observed. RESULTS RA and control groups had significantly different thicknesses of synovium, extensor and flexor tendon sheaths (P <.001). In RA group, 14.15% of joints had cavity fluid, 5.23% had cartilage destruction, and 2.32% of bone cortices had tendon sheath effusion. The detection rates of tendon sheath effusion and tendon adhesion were 19.81% and 16.30% respectively. Anti-CCP antibody positive group had significantly different DAS28, Health Assessment Questionnaire score and rheumatoid factor positive rate from those of negative group (P <.05). Synovitis, cartilage destruction, bone erosion, tendon sheath effusion, and joint effusion were significantly positively correlated with these values (P <.05). Besides, 8.92% of joints had blood flow signals of thickening synovium, of which joints with signals in the active phase accounted for 4.37%. The resistance index (RI) of synovial artery was (0.58 ± 0.07). However, 0.94% of joints had synovial blood flow signals in the inactive phase, and RI of synovial artery was (0.67 ± 0.03). Anti-CCP antibody positive group was significantly more prone to bone erosion than negative group (P <.05). CONCLUSIONS For patients with early RA, high-frequency ultrasonography was more likely to detect articular cartilage destruction and bone erosion changes when anti-CCP antibody was positive. Combining anti-CCP antibody with ultrasonography can provide valuable evidence for the development of clinical treatment regimens.

Abstract
Angiogenesis is the complex process of creating new capillaries from preexisting blood vessels due to hypoxemia, injury or inflammation of the tissues. Numerous cytokines and cell mediators have been identified to induce and stimulate angiogenesis, but vascular endothelial growth factor (VEGF) is a key regulator. The role of proangiogenic factors in the pathogenesis of chronic arthritis is currently a subject of intensive investigations in adult patients with rheumatoid arthritis (RA) and, to a limited extent, in children with juvenile idiopathic arthritis (JIA). Recent studies has shown a significant correlation between proangiogenic marker concentrations and the severity of inflammation in either RA or JIA patients. The serum neovascularization markers correlate with the power Doppler ultrasound image of the inflamed joint and hypertrophic synovium, which may be connected with the disease activity. The aim of this paper is to describe the state of the art on the important role of angiogenesis in adult and childhood rheumatoid arthritis.

Abstract
BACKGROUND AND PURPOSE In response to hypoxic succinate accumulates in arthritis synovium, however, the implication is little known. This study aims to investigate whether succinate could act as a metabolic signal linking metabolic alternation with angiogenesis in arthritis synovium. EXPERIMENTAL APPROACH The interaction between elevated succinate and VEGF production was examined in endothelial cells. Succinate production, HIF-1α induction and angiogenesis in the hypoxic synovium of collagen-induced arthritis rats were also investigated. KEY RESULTS Intracellular succinate promoted VEGF production and induced angiogenic response dependent on HIF-1α induction in endothelial cells. Luciferase reporter assay showed that succinate increased VEGF expression through gene promoter activation dependent on HIF-1α induction. Intracellular succinate released into intercellular space, where extracellular succinate activated succinate receptor G-protein-coupled receptor 91 (GPR91) and induced VEGF production, further exacerbating angiogenesis. In addition, TGF-β1 treatment increased succinate production due to the reversal of succinate dehydrogenase (SDH) activation, and consistently, SDH inhibitor dimethyl malonate reduced angiogenesis in the arthritis synovium. CONCLUSION AND IMPLICATIONS More than an intermediate, succinate functioned as a signaling molecule to link metabolic reprograming with angiogenesis. Intracellular succinate induced angiogenesis through HIF-1α induction, while extracellular succinate acted on GPR91 activation, working together to disturb energy metabolism and exacerbate inflammation and angiogenesis in arthritis synovium. Our work suggested that suppression of SDH could prevent succinate accumulation and inhibit angiogenesis via blocking HIF-1α/VEGF axis. This finding not only provides a novel insight into angiogenesis, but also reveals a potential therapeutical strategy to attenuate revascularization in arthritis.

Abstract
Background Neoangiogenesis is a crucial event to promote the development of the hyperplasic proliferative pathologic synovium in Rheumatoid arthritis (RA). Ultrasound (US) is sensitive for detection of power Doppler (PD) vascularization. Objective To explore the associations between a set of complementary circulating angiogenic markers and a comprehensive US assessment in patients with RA. Patients and methods Serum levels of eight angiogenic markers were measured by quantitative ELISAs in a total of 125 patients with RA, who were all systematically assessed in parallel by PDUS, performed on 32 joints. Results Serum levels of soluble Vascular Cell Adhesion Molecule-1 (sVCAM-1) and Tie-2 were more likely to be increased in patients with synovial hyperemia detected on at least one joint (Power Doppler grade ≥1). sVCAM-1, Tie-2 and Angiostatin concentrations gradually increased together with the grade of the semiquantitative PDUS scale and concentrations of these three markers were markedly increased in patients with moderate to marked hyperemia (Power Doppler grade 2 and 3). Levels of sVCAM-1, Tie-2, and Angiostatin correlated with a global arthritis sum score, defined by the sum of the semiquantitative PDUS scores for all joints examined. Levels of Tie-2 and Placenta Growth Factor (PlGF) were associated with PDUS features indicating residual disease activity. Conclusion Our results support the relevance of measuring serum levels of vascular markers to evaluate the intensity and extent of synovial vascularization. Angiogenic markers, and particularly Tie-2, could be a valuable surrogate of active synovitis and their place in relation to PDUS in clinical practice deserve further investigation.

Abstract
High-resolution musculoskeletal ultrasound (MSUS) has been increasingly employed in daily rheumatological practice and in clinical research. In rheumatoid arthritis (RA), MSUS can be now considered a complement to physical examination. This method evaluates synovitis through gray-scale and power Doppler and it is also able to identify bone erosions. The utilization of MSUS as a marker of RA activity has received attention in recent literature. Current data account for good correlation of MSUS with classical measures of clinical activity; in some instances, MSUS appears to perform even better. Diagnosis of subclinical synovitis by MSUS might help the physician in RA management. With some variation, interobserver MSUS agreement seems excellent for erosion and good for synovitis. However, lack of MSUS score standardization is still an unmet need. In this review, we describe several MSUS scores, as well as their correlation with clinical RA activity and response to therapy. Finally, we look at the relationship of MSUS with synovial tissue inflammation and discuss future perspectives for a better interpretation and integration of this imaging method into clinical practice.

Abstract
The advent of hydroxyurea and advanced medical care, including immunizations has led to improved survival among patients with Sickle Cell Disease (SCD). This prolonged survival however, introduces a chronic inflammatory disorder, Rheumatoid Arthritis (RA), which presents at a relatively older age and is rarely reported among SCD patients. In this review, we highlight the epidemiological association of SCD-RA and discuss the underlying common pathogenetic mechanisms, such as endothelial dysfunction, the role of inflammatory cytokines and oxidative stress. We also point to the difficulties in ascertaining the clinical diagnosis of RA in SCD patients. Finally, we provide rationale for therapeutic options available for RA and the challenges in the management of these patients with agents that are known to increase the risk of infection and immunosuppression such as steroids, disease modifying anti-rheumatic drugs and biologics.

Calprotectin (S100A8/A9) has the strongest association with ultrasound-detected synovitis and predicts response to biologic treatment: results from a longitudinal study of patients with established rheumatoid arthritis. Arthritis Res Ther 2017; 19:3. [PMID: 28081709 PMCID: PMC5234113 DOI: 10.1186/s13075-016-1201-0] [Citation(s) in RCA: 42] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2016] [Accepted: 12/01/2016] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Calprotectin (S100A8/A9 or MRP8/14) and S100A12 (leukocyte-derived proteins), interleukin 6 (IL-6) and vascular endothelial growth factor (VEGF) are markers of inflammation and angiogenesis. Ultrasound (US) is sensitive for detection of greyscale synovitis and power Doppler (PD) vascularization. The objective of the present study was to explore the associations between calprotectin, S100A12, IL-6, VEGF, erythrocyte sedimentation rate, C-reactive protein and a comprehensive US assessment in patients with rheumatoid arthritis (RA) starting biologic disease-modifying anti-rheumatic drug (bDMARD) treatment. METHODS A total of 141 patients with RA were assessed by US, clinical examination and biomarker levels at baseline and at 1, 2, 3, 6 and 12 months after initiation of bDMARDs. US assessment of 36 joints and 4 tendon sheaths were scored semi-quantitatively (0-3 scale). European League Against Rheumatism (EULAR) response was calculated. Statistical assessments performed to explore the associations between biomarkers and US sum scores included Spearman's rank correlation analysis as well as linear and linear mixed model regression analyses. RESULTS Calprotectin showed the overall strongest correlations with both US sum scores (r s = 0.25-0.62) and swollen joint counts (of 32) (r s = 0.24-0.47) (p < 0.05 at all examinations). An association with US sum scores remained after we adjusted for age, sex, disease duration and all the other markers in a regression analysis at baseline. Decreased calprotectin at the first month was predictive of both EULAR response (p ≤ 0.001) and decreased sum PD scores at 3, 6 and 12 months (p ≤ 0.05). CONCLUSIONS Calprotectin had the highest association with US synovitis and predicted treatment response. It may thus be considered as a marker for evaluating inflammation and responsiveness in patients with RA on bDMARD treatment.

Abstract
OBJECTIVES Binding immunoglobulin protein (BiP) is a human endoplasmic reticulum-resident stress protein. In pre-clinical studies it has anti-inflammatory properties due to the induction of regulatory cells. This randomized placebo-controlled, dose ascending double blind phase I/IIA trial of BiP in patients with active RA, who had failed accepted therapies, had the primary objective of safety. Potential efficacy was measured by DAS28-ESR and changes in biomarkers. METHODS Twenty-four patients with active RA who had failed one or more DMARDs were sequentially assigned to three groups each of eight patients randomly allocated to receive placebo (two patients) or BiP (six patients), 1, 5 or 15 mg. Patients received a single i.v. infusion over 1 h and were observed as inpatients overnight. A 12-week follow-up for clinical, rheumatological and laboratory assessments for safety, efficacy (DAS28-ESR) and biomarker analysis was performed. RESULTS No infusion reactions or serious adverse drug reactions were noted. Adverse events were evenly distributed between placebo and BiP groups with no BiP-related toxicities. Haematological, renal and metabolic parameters showed no drug-related toxicities. Remission was only achieved by patients in the 5 and 15 mg groups, and not patients who received placebo or 1 mg BiP. Good DAS28-ESR responses were achieved in all treatment groups. The BiP responding patients showed significantly lower serum concentrations of CRP, 2 weeks post-infusion compared with pre-infusion levels, and of VEGF and IL-8 from the placebo group. CONCLUSION BiP (⩽15 mg) is safe in patients with active RA. Some patients had clinical and biological improvements in RA activity. BiP merits further study.

Abstract
Synovial angiogenesis is considered to be an important early step in the pathogenesis of juvenile idiopathic arthritis (JIA). In this study we assessed levels of angiogenic markers in serum or synovial fluid and their possible relevance to disease activity or degree of ultrasound signs of synovial inflammation and angiogenesis in early JIA. The concentration of vascular endothelial growth factor (VEGF), its soluble receptors 1 and 2 (sVEGF-R1, sVEGF-R2), and angiopoietins 1 and 2 (ANG-1, ANG-2) were evaluated in 43 JIA patients and 23 healthy controls. Synovial angiogenesis was assessed by means of Power-Doppler Ultrasonography (PDUS), according to the fourth-grade vascularity scale. VEGF and its receptors' (sVEGF-R1, sVEGF-R2) serum levels were significantly higher in JIA patients (p = 0.002). We found large variation in serum ANG-1 and ANG-2 levels. The PDUS imaging identified increased synovial microvascular blood flow in 15 (35.7%) examined JIA children. Intensity of joint vascularization correlated with higher serum VEGF and its levels was lowest in grade 0 and highest in grade 3 (p < 0.007 and p < 0.001, resp.). In conclusion, the high correlation between synovial microvascular blood flow, serum angiogenic proteins, and symptoms of synovitis may indicate its important role in pathogenesis of JIA.

Abstract
OBJECTIVE To evaluate an association between synovial Doppler flow and serum levels of vascular endothelial growth factor (VEGF), angiogenin and TIMP-2 in patients with rheumatoid arthritis during anti-inflammatory treatment with glucocorticoids and TNF-α inhibitors. METHODS Inflamed wrists of 15 patients with rheumatoid arthritis (RA) were examined by two independent ultrasound investigators prior to and at days 3, 7, 14 and 42 after the initiation of treatment with glucocorticoids in therapy-naïve patients or after the beginning of a therapy with a TNF-α inhibitor in patients with DMARD failure. Quantitative three-dimensional power Doppler ultrasonographic assessment of synovial vascularization was compared at each visit with serum levels of VEGF, angiogenin and TIMP-2. RESULTS In the glucocorticoid group, synovial Doppler signals decreased significantly at day 3 (-44%; P=0.003) in comparison to a delayed decrease in the TNF-α inhibitor group after 6 weeks (-46%; P=0.001). A significant reduction of serum VEGF levels could be determined with a delay of 1 week after the decrease of Doppler activity but no correlation was found between both parameters (rho: P=0.7; r=-0.03). Angiogenin concentrations decreased in the TNF group and increased in the GC group. Levels of TIMP-2 did not change significantly in both groups. CONCLUSION The decrease of serum VEGF levels under treatment with glucocorticoids or TNF-α inhibitors followed the reduction of the intra-articular synovial Doppler flow. This result supports the idea that the reduction of synovial perfusion due to anti-inflammatory treatment is not regulated by systemic VEGF, but that the inflamed joints are the source for circulating VEGF.

Abstract
Objective.To investigate the stability over 2 weeks of ultrasonographic assessments of synovial thickness and vascularity in all 10 metacarpophalangeal joints of subjects with rheumatoid arthritis (RA) with a range of disease activities as measured by the validated Disease Activity Score-28 joint score (DAS28-ESR). And in subjects with severe disease activity, to compare the sensitivity of these measurements, acute-phase markers, and vascular endothelial growth factor to change in response to 2 weeks of oral prednisolone (7.5 mg daily).Methods.A group of 38 subjects with RA were enrolled, 13 (mean DAS28 2.1), 14 (mean DAS28 5.2), and 11 (mean DAS28 5.7) meriting oral corticosteroid treatment. Synovial thickness and vascularity were assessed by ultrasonography at 3 timepoints. Images were ranked by semiquantitative scale. Vascularity was also measured by quantitative determination of the power Doppler area (PDA).Results.In the whole RA cohort, baseline indices of synovial thickness and vascularity correlated with DAS28, as did PDA (r = 0.42, p < 0.05). In the RA groups on stable therapy, synovial thickness and vascularity showed little variation over 2 weeks. In the corticosteroid group, PDA had fold changes of −1.9-fold (p < 0.05) after 1 week and −2.2-fold (p < 0.05) after 2 weeks. These were the largest fold changes of all measured variables.Conclusion.Ultrasonographic measures can differentiate disease severity in RA correlating closely with DAS28. Quantitative power Doppler signal was significantly reduced within 1 week of oral prednisolone, a rapid kinetic suggesting that PDA may have value as a sensitive early marker of therapeutic response.

Abstract
OBJECTIVE To perform a systematic review on the reliability of ultrasonographic (US) synovitis detection in rheumatoid arthritis (RA) by B-mode and power Doppler (PD) in image acquisition and still-image interpretation. US is a sensitive method for synovitis detection. However, reliability is still a key concern. METHODS Articles reporting any US reliability results for synovitis in RA in PubMed, EMBase, the Cochrane Library, and meeting abstracts were selected. Data were extracted from the collection of data on US synovitis detection (either qualitatively [binary] or semiquantitatively [0-3 scale], for intraobserver and interobserver reliability in B-mode and PD, and for image acquisition and still-image interpretation). The type of joints tested, the experience of the ultrasonographer, and the quality of the studies were assessed. Data analysis involved descriptive and graphic interpretation of reliability and its potential determinants. RESULTS Thirty-five studies (12 for B-mode, 11 for PD, or 12 for both) with a total of 1,415 patients were analyzed. Intraobserver and interobserver reliability for still images in B-mode and PD was high (kappa = 0.5-1.0 [14,991 joints] for intraobserver reliability for B-mode, kappa = 0.59-1.0 [14,934 joints] for PD, kappa = 0.49-1.0 [3,138 joints] for interobserver for B-mode, and kappa = 0.66-1.0 [3,325 joints] for PD). Interobserver reliability for image acquisition in both US modes was lower than still-image interpretation (kappa = 0.22-0.95). Few studies reported intraobserver image acquisition reliability. CONCLUSION Intraobserver and interobserver reliability of still-image interpretation was high, especially for PD, in published studies involving highly trained observers. However, reliability of acquisition of US should be further assessed.

Abstract
Objective.To evaluate the clinical significance of serum levels of vascular endothelial growth factor (VEGF), angiopoietin-1 (Ang-1), and angiopoietin-2 (Ang-2) in patients with rheumatoid arthritis (RA).Methods.The subjects were 70 patients with RA. Serum VEGF, Ang-1, and Ang-2 levels were determined by ELISA. As indices of disease activity, serum levels of C-reactive protein (CRP) and matrix metalloprotease (MMP)-3 were examined, and the 28-joint count Disease Activity Score (DAS28)-CRP was calculated. Power Doppler ultrasonography was performed in the bilateral wrists, elbows, shoulders, knees and ankles. The synovial blood flow signals were scored using a 3-grade scale (0–2), and the total of the scores in the 10 joints was regarded as the total signal score (TSS).Results.Serum VEGF level showed significant correlations with serum CRP and MMP-3 levels, DAS28-CRP, and TSS. Serum Ang-1 level showed significant correlations with serum MMP-3 level and DAS28-CRP. Serum Ang-2 level showed significant correlations with serum CRP level and TSS.Conclusion.The serum VEGF level is important as an index of the activity of RA based on angiogenesis and a prognostic factor regarding joint destruction. Serum Ang-1 level may be useful as an index of sustained arthritis based on the maintenance of newly formed vessels. Serum Ang-2 level may reflect a state of marked angiogenesis.

Abstract
The objective of the study is to examine the relationship between synovial blood flow signals and vascular endothelial growth factor (VEGF) involved in angiogenesis by Doppler ultrasound. Twenty-one patients meeting the diagnostic criteria of the American College of Rheumatology (ACR) were enrolled in this study. Doppler ultrasound signals of blood flow in the wrist synovial membrane were measured and classified into three grades: grade 1 = no flow; grade 2 = mild flow; grade 3 = intense flow. A significant correlation was observed between blood flow signals in the wrist synovial membrane and serum VEGF levels (r = 0.5681, P = 0.0072). These results suggest that the measurement of Doppler ultrasound signals of blood flow in the wrist synovial membrane is useful in the evaluation of angiogenesis.

Abstract
OBJECTIVE The purpose of this study was to evaluate 3-dimensional (3D) ultrasonography for the visualization of intra-articular synovial hypertrophy in patients with osteoarthritis. METHODS Knee joints of 22 patients with osteoarthritis were examined by 3D ultrasonography, and their synovial fluids were analyzed. Ultrasonographic image patterns, vascular endothelial growth factor and transforming growth factor beta concentrations in synovial fluid, and serum inflammatory markers were analyzed. RESULTS It was possible to visualize the intra-articular structure by 3D ultrasonography. Three-dimensional ultrasonography revealed various interesting stereoscopic views of the synovial structures, and the patterns of synovial proliferation ranged from simple proliferations to complex shrubby structures. Patients with a more complex and proliferative pattern in the synovium tended to have higher C-reactive protein concentrations, but this difference was not significant (P = .09). The concentrations of vascular endothelial growth factor and transforming growth factor beta in synovial fluid were significantly higher in patients with complex hypertrophy (P < .05). CONCLUSIONS Three-dimensional technology was useful in delineating the shape of the synovium. It may have a possible impact on future imaging in rheumatology.

Abstract
PURPOSE To evaluate whether ultrasmall superparamagnetic iron particles (USPIO)-enhanced MRI is capable of assessing both synovial perfusion characteristics and the presence of synovial macrophages in a model of antigen-induced arthritis. MATERIALS AND METHODS Unilateral arthritis was induced in six knees of six rabbits. The contralateral knees of the rabbits served as control knees. After onset of arthritis, all 12 knees were scanned prior to and immediately following intravenous administration of USPIO using a multiphase T1-weighted (T1w) fast gradient-echo (FGRE) sequence, and T1w spin-echo (SE), T2-weighted (T2w) FSE, T2*w GRE, and short-tau inversion recovery (STIR) sequences prior to and 24 hours following USPIO administration. SI-vs.-time curves (STCs) and the early enhancement rate during the first 56 seconds (REE(56)) were calculated from SI measurements within the synovial tissue of all knees on dynamic T1w images. MR findings were correlated to histopathology. RESULTS REE(56) was significantly higher in the synovial tissue of arthritic knees than in the control knees (P < 0.01). Significant T1-, T2-, and T2* effects (P = 0.03-0.04) and multiple synovial vessels were visually detectable within the arthritic synovial tissue 24 hours after administration of USPIO, whereas no signal changes or synovial vessels were seen in the control knees. Histopathology revealed widened synovial blood vessels in the arthritic knees, and confirmed iron uptake by macrophages in the arthritic knees. CONCLUSION USPIO-enhanced MRI is capable of both assessing synovial hyperperfusion and detecting macrophages in antigen-induced arthritis in rabbits.

Abstract
OBJECTIVE To evaluate the sensitivity to change of power Doppler ultrasound (PDUS) assessment of joint inflammation and the predictive value of PDUS parameters in disease activity and radiologic outcome in patients with early rheumatoid arthritis (RA). METHODS Forty-two patients with early RA who started therapy with disease-modifying antirheumatic drugs underwent blinded sequential clinical, laboratory, and ultrasound assessment at baseline, 3 months, 6 months, and 1 year and radiographic assessment at baseline and 1 year. For each patient, 28-joint Disease Activity Score (DAS28) was recorded at each visit. The presence of synovitis was investigated in 28 joints using gray-scale ultrasonography and intraarticular power Doppler signal. Active synovitis was defined as intraarticular synovitis detected with power Doppler signal. The ultrasound joint count for active synovitis and an overall joint index for power Doppler signal were calculated. Sensitivity to change of PDUS variables was assessed by estimating the smallest detectable difference (SDD) from the intraobserver variability. RESULTS The SDD for ultrasound joint count for active synovitis and ultrasound joint index for power Doppler signal was lower than mean changes from baseline to 3 months, 6 months, and 1 year. Time-integrated values of PDUS parameters demonstrated a highly significant correlation with DAS28 after 1 year (r = 0.63, P < 0.001) and a stronger correlation with radiographic progression (r = 0.59-0.66, P < 0.001) than clinical and laboratory parameters (r < 0.5). CONCLUSION PDUS is a sensitive and reliable method for longitudinal assessment of inflammatory activity in early RA. PDUS findings may have a predictive value in disease activity and radiographic outcome.

Abstract
OBJECTIVE To compare three-dimensional (3D) power Doppler ultrasonography (PDUS) with contrast enhanced magnetic resonance imaging (MRI) in their capability to visualize synovial vascularity in inflamed wrists of patients with rheumatoid arthritis (RA). METHODS Nine patients with RA showing clinically active arthritis of the wrist as determined by tenderness and swelling were examined by contrast enhanced MRI and 3D PDUS. Vascularity close to and inside the joint capsule was visualized by conventional power Doppler mode. In a region with high Doppler signal intensity (=region of interest/ROI) a 3D blood vessel tree was obtained by a free-hand sweep. 3D images were evaluated with regard to the number of blood vessels in the intra- and peri-articular region. MRI examinations were performed using a 1.5 T Scanner. In MRI, time resolved coronal contrast enhanced T1-weighted sequences with fat suppression were acquired during an 8 min period to assess tissue enhancement. Relative enhancement was calculated and compared to 3D PDUS findings. RESULTS A 3D vascular tree consisting of peri- and intra-articular blood vessels could be demonstrated in the same anatomical ROI in which an increased gadolinium enhancement was measured by MRI in all examined RA patients. The number of penetrating vessels into the joint capsule, the number of intra-articular vessels and a semiquantitative estimation of the strength of blood flow were used to generate a 3D score for the intensity of synovial vascularity. CONCLUSION When compared with clinical symptoms and the gold standard dynamic MRI, 3D PDUS is a reliable imaging technique for assessing synovial vascularity in inflamed wrists of RA patients.

Abstract
OBJECTIVE To evaluate the performance characteristics of power Doppler ultrasound as a diagnostic and monitoring tool in the assessment of musculoskeletal disease through a systematic review of the literature. METHODS SEARCH STRATEGY We performed a literature search of PUBMED (1966 to June 2005). SELECTION CRITERIA Only original research reports written in English involving musculoskeletal disease and power Doppler ultrasound were included. Reviews were noted but not included. Data Extraction/Reporting: The design, subjects, methods, imaging protocols, and performance characteristics studied in the research papers were reported. RESULTS Of 3568 identified reports, 139 involved power Doppler ultrasound of the musculoskeletal system. Fifty-three of these reports met the inclusion criteria. Ultrasound machine settings were specified in 63% of reports. Rheumatoid arthritis was the most commonly studied musculoskeletal disease (64% of papers). Validity was the most studied performance characteristic (94% of reports), while reliability and responsiveness were studied in 17 and 34%, respectively. CONCLUSIONS Although the majority of research reports of power Doppler ultrasound assessment of the musculoskeletal system evaluated validity, less than half reported reliability and responsiveness. Further work is needed to evaluate power Doppler ultrasound assessment of the musculoskeletal system before it can be used to guide clinical decisions or be used as an endpoint in clinical trials.

Abstract
Rheumatoid arthritis (RA) is a chronic and progressive inflammatory disorder primarily affecting the synovium and is characterized by destruction of bone and cartilage. Early diagnosis and treatment of RA can improve disease outcomes substantially. Magnetic resonance imaging and musculoskeletal ultrasonography may facilitate early diagnosis and aid the targeting of intensive therapy. Magnetic resonance imaging and musculoskeletal ultrasonography also are able to monitor temporal changes in disease activity (ie, synovitis) and damage (ie, erosions). These imaging modalities are likely to be increasingly used in the management of early rheumatoid arthritis to ensure the best patient outcomes, although more work is required to determine their optimal roles.

Abstract
UNLABELLED To compare the effect of oral glucocorticoid (GC) therapy with the effect of intravenous anti-TNF-alpha-therapy on serum VEGF levels of patients with rheumatoid arthritis (RA). Five RA patients (5/8) who had no prior treatment with DMARDs (Disease modifying antirheumatic drugs) or GCs were administered 20 mg prednisolone daily. Three patients who failed more than one DMARD therapy received infusion with Infliximab (200 mg). VEGF-serum levels were measured by enzyme-linked immunosorbent assay before treatment,and at day 10 or 13 during prednisolone therapy, or 14 days after the first Infliximab infusion. Serum VEGF levels in therapy naive RA patients (GC group) were higher than those in pretreated patients who received Infliximab (median serum VEGF level: 1106 vs 320 pg/ml; P=0.1). Treatment with Infliximab as well as GCs significantly decreased serum VEGF levels after 10-14 days in RA patients (median serum VEGF level after treatment: GC group 559 pg/ml, Infliximab group 92 pg/ml; P=0.01 vs without treatment or preinfusion). CONCLUSIONS Anti-TNF-alpha antibody Infliximab as well as GC are able to decrease serum VEGF levels in patients with active RA. Whether therapeutic reduction of serum VEGF levels is associated with inhibition of angiogenesis should be evaluated in future by imaging of synovial vasculature.

Abstract
Vascular pathology, in the form of angiogenesis, is important in the perpetuation of rheumatoid arthritis (RA) and, in the form of endothelial dysfunction, contributes to associated cardiovascular co-morbidity. Emerging evidence suggests that TNFalpha blockade may modify vascular pathology in RA. Serum concentrations of vascular endothelial growth factor (VEGF), a potent endothelial cell-specific growth factor that is up-regulated by pro-inflammatory cytokines and by hypoxia, are elevated in RA and correlate with disease activity. Serum levels of VEGF at first presentation in RA predict radiographic progression of the disease over the subsequent year. Power Doppler ultrasonography is a sensitive method for demonstrating the presence of blood flow in small vessels and the vascular signal correlates with histopathological quantification of the vascular density of synovial tissue. Recent data indicate that high-frequency ultrasound and power Doppler are sensitive tools for evaluation of disease activity and assessment of response to therapy. Power Doppler imaging may also have the potential to predict those patients most at risk of accelerated joint destruction. However, much work has yet to be done to standardize the use of these imaging technologies.
