Background: Nowadays, rheumatologists face challenges in finding an effective method to classify and treat patients with undifferentiated arthritis (UA). There is a need for new tools that could ensure accurate characterization of inflammatory processes in these patients., Objective: The aim of this study was to investigate if a characterization of UA patients using ultrasound (US) may help to fulfill the 2010 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) rheumatoid arthritis (RA) classification criteria in a real-life cohort., Methods: We conducted a cross-sectional study in 2 rheumatology care clinics. Patients not fulfilling the 2010 ACR/EULAR RA criteria were included. On the examination day, all patients underwent a physical examination, radiography, and US. The 7-joint US score was adopted to scan all patients. The US was performed according to EULAR criteria and interpreted by Outcome Measures in Rheumatology definitions. Gray-scale and power Doppler synovitis and tenosynovitis were scored. Bone erosions were also evaluated during the US examination., Results: A total of 204 patients were included. The diagnosis was modified from UA to RA in 86 patients (42.1%). Also, the final score of the 2010 ACR/EULAR RA classification criteria changed from a mean of 4.6 to 6.5 after the US examination. In addition to synovitis, a wide range of tenosynovitis and bone erosions were detected by US. Synovitis was more frequently detected in second metacarpophalangeal joint followed by second metatarsophalangeal joint (MTPj) and fifth MTPj. The tendons of the wrist and second and third fingers were the most affected. In relation to bone erosions, second metacarpophalangeal joint and fifth MTPj were the joints with more proportion of anatomical damage., Conclusions: The US demonstrated to be useful to help accurately classify as RA patients previously diagnosed with UA.

Objective: There are different imaging techniques to assess the parotid glands (i.e., sialography, salivary gland scintigraphy) in patients with Sjögren syndrome (SS). However, their use is limited by the invasive character or high cost. Ultrasound (US) is gaining interest by rheumatologists as a complementary diagnostic tool for SS. To date, there is an increasing body of evidence supporting its sensitivity in the assessment of salivary glands in SS. The aim of our study was to analyze the potential role of US as a diagnostic and prognostic tool in SS and to discuss existing evidence to support its application use., Methods: A systematic search was performed in the electronic database PubMed, using the following search terms: (salivary glands OR parotid glands OR submandibular glands) AND Sjögren's syndrome AND (ultrasonography OR ultrasound OR sonography). Titles, abstracts, and full reports were systematically screened., Results: The results of the studies analyzed in this review show encouraging results in terms of accuracy, validity, and diagnostic value, which leads us to believe that in the future US could become the reference imaging tool to assess SS. The studies include a small cohort of patients, and there is no standardized approach in terms of US techniques for the assessment of salivary glands., Conclusions: Ultrasound of major salivary glands is a useful tool for diagnosis, prognostic evaluation, and response to treatment in SS. The use of this imaging technology is still under development, and more multicentric studies are needed to validate this tool.

Background: Adherence to biologic therapy is relatively poorly studied in rheumatoid arthritis (RA) because many of the studies have investigated the drug persistence, which represents only a surrogate of adherence., Objectives: The aims of this study were to determine the extent of adherence in RA patients with subcutaneously administered anti-tumor necrosis factor methotrexate agents and to identify the risk factors for nonadherence., Methods: A cohort of RA patients who started a subcutaneous anti-tumor necrosis factor treatment were enrolled. After 12 months of treatment, all patients completed the 4-item Morisky Medication Adherence Scale questionnaire. Associations between beliefs and nonadherence and the influence of demographic, clinical, and radiographic features were assessed using logistic regression model., Results: A total of 209 (80.4%) of the 260 patients were included in the analyses. Forty-three of 209 patients were considered nonadherent to their medication (20.6%) according to the 4-item Morisky Medication Adherence Scale. More than half (53.1%) of patients showed at least 1 form of nonadherent behavior.The logistic model showed that low disease activity (P = 0.003), higher patient-physician discordance ratings (P = 0.012), older age (P = 0.041), and a high number of comorbid conditions (P = 0.011) were significantly associated with increased likelihood of nonadherence., Conclusions: The overall nonadherence with subcutaneous biologic therapy is relatively high among RA patients and should be taken into account when a patient's response to treatment is unsatisfactory.

Over the years, ultrasound (US) has accumulated important evidence supporting its relevant role for the assessment of inflammatory processes of different rheumatologic diseases, as well as in the follow-up in assessing the response to different therapeutic approaches. This has been possible because of the increase in training, competency, and knowledge, as well as the rapid progress in the US technologies.Currently, some US machines can be equipped by sophisticated software modalities (i.e., 3-dimensional US, elastosonography, automated cardiovascular software, and fusion imaging) that can augment US traditional role as a safe, fast, and easy-to-perform modality and giving it new life and increased relevance in rheumatology. In this article, we evaluated the US developments, from conventional B-mode to more sophisticated technologies, and their potential clinical impact in the field of rheumatology.Three-dimensional US can improve the accuracy of the assessment of bone erosions and the quantification of power Doppler because of its multiplanar view including coronal, axial and sagital view. Elastosonography is still looking for its role in rheumatology. Preliminary works induce us to consider it as a promise tool for the assessment of tendon pathology and skin of patients with connective tissue disorders. The automated method for the measurement of carotid intima-media thickness permits a rapid and accurate assessment. The preliminary published data showed that it is reliable, and valid compared to the traditional method; they also support the future of rheumatologists as the direct operators in evaluating the cardiovascular risk in daily practice. Fusion imaging increases the diagnostic power of US, displaying simultaneously in the monitor, the US image, and the corresponding computed tomography/magnetic resonance imaging image. However, there are no sufficient data supporting its application in daily rheumatologic practice.

Ultrasound (US) is a cost-effective, noninvasive, and accessible imaging modality that clinicians use at the point of care to assess disease activity and therapeutic efficacy in different rheumatic conditions. It can play a relevant role in invasive procedures performed by the rheumatologist, potentially ensuring a higher degree of accuracy. However, US-guided injections are still underused, and the conventional blind injection the most commonly adopted approach. In this article, we analyze the current evidence supporting the use of US-guided procedures, emphasizing comparative studies between conventional and US-guided procedures and their benefits in the daily rheumatological practice.

Ultrasound (US) is a noninvasive imaging technique that continues to gain interest among rheumatologists because of its undoubted utility for the assessment of a wide range of abnormalities in rheumatic diseases. It also has a great potential to be used at the time of consultation as an extension of the clinical examination.Current data demonstrate that the standard clinical approach could result in an insensitive assessment of some the different aspects of the various rheumatic diseases for which US has become a feasible and effective imaging modality that allows early detection of anatomical changes, careful guidance for the aspiration and/or local treatment, and short- and long-term therapy monitoring at the joint, tendon, enthesis, nail, and skin levels. The spectrum of pathological conditions for which US plays a crucial role continues to increase over time and includes rheumatoid arthritis, spondyloarthropathies, osteoarthritis, crystal-related arthropathies, connective tissue disorders, and vasculitis.It is expected that the inclusion of more longitudinal studies with a larger number of patients and more rigorous methodological approach will undoubtedly provide a better understanding of the significance of the abnormal US findings detected in order to provide the proper diagnostic and/or therapeutic approaches. In this article, we analyze the current potential applications of US in rheumatology and discuss the evidence supporting its use in the daily rheumatologic practice.

Background: Ultrasound has demonstrated to be a highly sensitive tool in the evaluation of entheses in spondyloarthropathy (SpA) patients and improves the ability of clinical examination to detect enthesopathy., Objectives: The objectives of the study were to determine the prevalence of subclinical enthesopathy in SpA patients and to evaluate the reliability of ultrasound in the detection of abnormal findings indicative of enthesopathy., Methods: Six hundred lower-limb entheses were assessed in 60 SpA patients without known history of entheseal involvement. Sixty rheumatoid arthritis patients and 30 control subjects were included as control groups. Clinical examination and ultrasound were consecutively performed at each of the entheses to detect signs indicative of enthesopathy. Images from 20 SpA patients were stored and afterward evaluated to determine the reliability of abnormal ultrasound findings., Results: Ultrasound detected a high prevalence of enthesopathy in SpA patients with respect to both rheumatoid arthritis patients and control subjects (P < 0.001 for both comparisons). In SpA patients, clinical examination detected enthesopathy in 56 (9.3%) of 600 entheses. In the remainder 544 clinically asymptomatic entheses (90.7%) (not painful and not swollen), ultrasound detected in 331 (60.8%) at least 1 ultrasound sign of enthesopathy. The intrareader and interreader agreement for all ultrasound abnormal findings was good to excellent., Conclusion: The present study demonstrates a higher sensitivity of ultrasound with respect to physical examination in the detection of signs indicative of enthesopathy in SpA patients with an adequate interreader and intrareader reliability. Further study is needed about the prognostic value of the ultrasound findings for predicting clinical onset of entheseal involvement.
