Objective: To define the role of ultrasound (US) for the assessment of patients with rheumatoid arthritis (RA) in clinical remission, including joint and tendon evaluation., Methods: A multicentre longitudinal study has been promoted by the US Study Group of the Italian Society for Rheumatology. 25 Italian centres participated, enrolling consecutive patients with RA in clinical remission. All patients underwent complete clinical assessment (demographic data, disease characteristics, laboratory exams, clinical assessment of 28 joints and patient/physician-reported outcomes) and Power Doppler (PD) US evaluation of wrist, metacarpalphalangeal joints, proximal interphalangeal joints and synovial tendons of the hands and wrists at enrolment, 6 and 12 months. The association between clinical and US variables with flare, disability and radiographic progression was evaluated by univariable and adjusted logistic regression models., Results: 361 patients were enrolled, the mean age was 56.20 (±13.31) years and 261 were women, with a mean disease duration of 9.75 (±8.07) years. In the 12 months follow-up, 98/326 (30.1%) patients presented a disease flare. The concurrent presence of PD positive tenosynovitis and joint synovitis predicted disease flare, with an OR (95% CI) of 2.75 (1.45 to 5.20) in crude analyses and 2.09 (1.06 to 4.13) in adjusted analyses. US variables did not predict the worsening of function or radiographic progression. US was able to predict flare at 12 months but not at 6 months., Conclusions: PD positivity in tendons and joints is an independent risk factor of flare in patients with RA in clinical remission. Musculoskeletal ultrasound evaluation is a valuable tool to monitor and help decision making in patients with RA in clinical remission., Competing Interests: Competing interests: None required., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Objective: To investigate the prognostic value of US in predicting musculoskeletal flares and Jaccoud׳s arthropathy (JA) in systemic lupus erythematosus (SLE)., Methods: A total of 80 out of 94 patients (76 female; age 45.5 ± 13.2 years) with non-deforming non-erosive (NDNE) arthritis and 48/60 healthy controls (42 female; age 49.6 ± 11.6 years) completed the 5-year follow-up study. Each patient was prospectively assessed for the occurrence of musculoskeletal flares using BILAG2004 and hand deformities according to Jaccoud׳s articular index. Baseline clinical, serological, semi-quantitative (0-3 scale) ultrasound (US) findings, PD-synovitis and PD-tenosynovitis scores were used as covariates to identify predictors of study outcomes. Short Form 36 v2 (SF36v2) health survey questionnaire was administered., Results: Overall, 12 MS flares in 10 (12.5%) patients were recorded and the incidence rate was 3.0 per 100 patient-year. Baseline PD-synovitis score independently predicted MS flare (p < 0.001; RR = 2.0; 95% CI: 1.4-3.0) within 2 years since US examination. In all, 5 (6.2%) patients developed JA whose incidence rate was 1.25 per 100 patient-year. Independent risk factors for development of JA were higher longitudinal BILAG score in the musculoskeletal domain (p = 0.005; RR = 2.4; 95% CI: 1.3-4.6) and longer disease duration (p = 0.013; RR 1.2; 95% CI: 1.1-1.3). JA and active musculoskeletal inflammation (BILAG ≥ C), but not US erosions, were associated with lower results in SF36v2 physical and mental summary components., Conclusions: Performing musculoskeletal US can be useful in order to predict MS flares. Jaccoud׳s deformities may arise in patients with long-standing SLE and prolonged, even subclinical, joint and tendon inflammation., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Objective: To assess the prevalence and the distribution of tendon involvement in the hands and wrists of patients with rheumatoid arthritis (RA) describing in detail the ultrasound (US) morphostructural and vascular tendon abnormalities., Methods: Ninety consecutive RA patients were included in the study. The following tendons were scanned bilaterally: flexor pollicis longus tendon, flexor digitorum superficialis, and profundus tendons of the II to the V fingers (at both finger and carpal tunnel levels), flexor carpi radialis tendon, and extensor tendons of the 6 compartments on the dorsal aspect of the wrist. The presence of US findings indicative of tenosynovitis and tendon damage was investigated., Results: Tenosynovitis was found in at least 1 anatomic site of 44 (48.8%) of 90 patients. Tendon damage was found in at least 1 anatomic site of 39 (43.3%) of 90 patients. The focal tendon echotexture derangement was found in 294 of 5400 (5.4%) tendons, the partial and complete tears in 14 (0.3%), and in 3 (0.06%) tendons, respectively. The most frequently involved tendons were the flexor tendons of the II, III, and IV fingers and the extensor carpi ulnaris tendon., Conclusions: The present study provides evidence in favor of the ability of US to reveal a relatively high frequency of tendon involvement at the hand and wrist level in RA patients. These data can both facilitate US examinations in daily clinical practice and direct further investigations in the US assessment of tendon involvement in RA., (Copyright © 2012 Elsevier Inc.

Objectives. This study aimed to estimate the prevalence of US-detected tenosynovitis in RA patients in clinical remission and to explore its clinical correlates. Methods. A total of 427 RA patients in clinical remission were consecutively enrolled from 25 Italian rheumatology centres. Tenosynovitis and synovitis were scored by US grey scale (GS) and power Doppler (PD) semi-quantitative scoring systems at wrist and hand joints. Complete clinical assessment was performed by rheumatologists blinded to the US results. A flare questionnaire was used to assess unstable remission (primary outcome), HAQ for functional disability and radiographic erosions for damage (secondary outcomes). Cross-sectional relationships between the presence of each US finding and outcome variables are presented as odds ratios (ORs) and 95% CIs, both crude and adjusted for pre-specified confounders. Results. The prevalence of tenosynovitis in clinical remission was 52.5% (95% CI 0.48, 0.57) for GS and 22.7% (95% CI 0.19, 0.27) for PD, while the prevalence of synovitis was 71.6% (95% CI 0.67, 0.76) for GS and 42% (95% CI 0.37, 0.47) for PD. Among clinical correlates, PD tenosynovitis associated with lower remission duration and morning stiffness while PD synovitis did not. Only PD tenosynovitis showed a significant association with the flare questionnaire [OR 1.95 (95% CI 1.17, 3.26)]. No cross-sectional associations were found with the HAQ. The presence of radiographic erosions associated with GS and PD synovitis but not with tenosynovitis. Conclusions. US-detected tenosynovitis is a frequent finding in RA patients in clinical remission and associates with unstable remission. [ABSTRACT FROM AUTHOR]

Objective. To estimate the prevalence of, and identify factors associated with, hand and wrist US alterations in a large cohort of SLE patients.Methods. One hundred and eight consecutive SLE patients were recruited and classified according to arthropathy type and the musculoskeletal item of the British Isles Lupus Assessment Group (BILAG) 2004 score. US examinations were performed on hand and wrist flexor tendons, wrist extensor tendons, second and third MCP and wrist joints bilaterally using a multi-planar scanning technique.Results. US examination showed joint involvement in 42/108 (38.8%) subjects, tendon involvement in 44/108 (40.7%) and both in 22/108 (20.3%). Patients with rhupus syndrome (n = 8) carried a higher incidence of inflammatory changes (87%) and erosions (87%) compared with the six with Jaccoud’s arthropathy (50% and 17%, respectively) and the 94 with non-deforming X-ray non-erosive arthropathy (37% and 21%, respectively). Power Doppler signal was prevalent in patients scoring A (n = 4) or B (n = 9) on the musculoskeletal item of the BILAG 2004, and was significantly more frequent at the joint (92%) and tendon (54%) level than in the 26 patients scoring C (19%, P = 0.0007 and 15%, P = 0.016, respectively) and in the 69 scoring D (3%, P < 0.0001 and 3%, P < 0.0001). US changes in patients who scored C or D were more expressed at the tendon level (50% and 29%, respectively) than at the joint level (35% and 9%, respectively).Conclusion. The picture of musculoskeletal US in SLE depends on arthropathy subtype and disease activity. US examination could be a valid and reliable tool to monitor musculoskeletal features and therapeutic outcomes in SLE patients. [ABSTRACT FROM PUBLISHER]
