RESUMO
OBJECTIVE: To assess the accuracy of ultrasound (US) versus fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) to identify extracranial involvement in large vessel vasculitis (LVV). METHODS: A retrospective observational study of patients with suspected LVV. All patients underwent US exam within 24 h per protocol. FDG-PET/CT was performed according to clinician criteria. The gold standard for LVV diagnosis was clinical confirmation after 6 months. RESULTS: Of the 113 patients included (74.3% female, mean age 74 years), 37 (32.7%) were diagnosed with LVV after 6 months. The sensitivity and specificity of US were 86.5% and 96.1%, respectively. Only 12 (42.9%) of 28 patients undergoing a FDG-PET/CT per clinician criteria showed positive findings. The sensitivity and specificity of FDG-PET/CT for LVV were 61.1% and 90%, respectively. Taking FDG-PET/CT as the reference, US showed extracranial inflammation in 10/12 (83.3%) and detected 2 (12.5%) additional cases of extracranial involvement with negative FDG-PET/CT. Conversely, FDG-PET/CT was positive in two patients with negative US (one isolated aortitis and one aortoiliac involvement). CONCLUSIONS: US and FDG-PET/CT are both valid tools to detect extracranial involvement. The presence of US extracranial artery inflammation is consistent with FDG-PET/CT examination, although a negative US scan does not rule out extracranial involvement.

METHODS: We conducted a single-center, medical records review study of all patients with RA, PsA, and SpA on GLM treatment attending a large rheumatology department from 2010 to 2017. Times from start to end of GLM treatment were collected, as well as sociodemographic, clinical, and safety variables. Golimumab retention rate was estimated by the Kaplan-Meier method, and comparison across diseases was analyzed with the Mantel-Haenszel statistic (log-rank test). Cox proportional hazards regression models were used to identify factors associated with GLM discontinuation. RESULTS: In the study period, a total of 212 patients (61 RA, 48 PsA, 103 SpA) were prescribed GLM. Retention rates were 72% in the first year, 61% in the second, 56% in the third, and 38% at 5 years. Differences were statistically significant across diseases (median times to GLM discontinuation were 50.2, 46.0, and 38.7 months for RA, SpA, and PsA, respectively) and according to the number of previous biologic therapies (55.2 months in biologic-naive patients vs 14.0 months in patients with ≥2 previous biologics; p < 0.001). The use of concomitant conventional synthetic disease-modifying antirheumatic drugs was associated with a lower probability of discontinuation (hazards ratio [HR], 0.57; 95% confidence interval [CI], 0.33-0.97). Female sex (HR, 1.84; 95% CI, 1.07-3.17) and having used 2 biologics before GLM (HR, 2.99; 95% CI, 1.76-5.06) were associated with increased discontinuation rates. Twenty-three patients (10.9%) had at least 1 serious adverse event. CONCLUSIONS: In a real-life setting, GLM shows appropriate long-term safety-effectiveness ratio.

OBJECTIVE: Sjögren syndrome in children is a poorly understood autoimmune disease. We aimed to describe the clinical and diagnostic features of children diagnosed with Sjögren syndrome and explore how the 2016 ACR/EULAR classification criteria apply to this population. METHODS: An international workgroup retrospectively collected cases of Sjögren syndrome diagnosed under 18 years of age from 23 centres across eight nations. We analysed patterns of symptoms, diagnostic workup, and applied the 2016 ACR/EULAR classification criteria. RESULTS: We identified 300 children with Sjögren syndrome. The majority of patients n = 232 (77%) did not meet 2016 ACR/EULAR classification criteria, but n = 110 (37%) did not have sufficient testing done to even possibly achieve the score necessary to meet criteria. Even among those children with all criteria items tested, only 36% met criteria. The most common non-sicca symptoms were arthralgia [n = 161 (54%)] and parotitis [n = 140 (47%)] with parotitis inversely correlating with age. CONCLUSION: Sjögren syndrome in children can present at any age. Recurrent or persistent parotitis and arthralgias are common symptoms that should prompt clinicians to consider the possibility of Sjögren syndrome. The majority of children diagnosed with Sjögren syndromes did not meet 2016 ACR/EULAR classification criteria. Comprehensive diagnostic testing from the 2016 ACR/EULAR criteria are not universally performed. This may lead to under-recognition and emphasizes a need for further research including creation of paediatric-specific classification criteria.

OBJECTIVES: Subclinical synovitis is often detected by musculoskeletal ultrasound (MSUS) in juvenile idiopathic arthritis (JIA) patients in clinical remission. The main objective of this prospective, observational, longitudinal, multicentre study was to evaluate the predictive value of MSUS-detected subclinical synovitis in relation to flares at 12 months following TNFi tapering in a JIA population in stable clinical remission. METHODS: We included 56 JIA patients in stable remission undergoing TNFi therapy tapered at baseline and in some cases at 6 months. We performed baseline and 6-month MSUS assessment on B-mode (BM) and power Doppler (PD) mode of 22 joints and 8 tendons. RESULTS: Eighteen patients (32.1%) experienced a flare during the 12-month study period. BM synovitis was frequent (83.9%) but PD synovitis was scarcely found (8.9%). There were no significant differences in MSUS findings between patients who experienced a flare and those who remained in remission. Only 5 patients had positive for PD synovitis, in joints with BM synovitis grades 2 or 3, and none experienced a flare. Concomitant methotrexate (MTX) was more frequent in patients who were successfully tapered (71.1% vs. 27.8%; p=0.002) and patients older than 12 experienced a greater number of flares and earlier onset. CONCLUSIONS: Subclinical synovitis, as detected by MSUS, proved not to be a predictor of flares. Those patients on a TNFi-tapered concomitant methotrexate regimen experienced the fewest flares although flare risk increased with age.

OBJECTIVE: To compare structural damage assessed by conventional radiography and tendon damage assessed by musculoskeletal US (MSUS) at wrist and ankle in RA patients. METHODS: We evaluated 72 consecutive patients [56 (77.8%) females] with RA. The MSUS evaluation consisted in a B-mode examination of bilateral extensor carpi ulnaris and tibialis posterior tendons. Tendon damage was defined and scored according to OMERACT. A total score for the tendon damage score (TDS) was calculated by summing the grades for each tendon. For the radiographic evaluations we used the van der Heijde score; a total radiographic score (RTS) was calculated by summing a bone erosion score (ERS) and a joint space narrowing score (JSNS). RESULTS: We evaluated 288 tendons. The mean (s.d.) of TDS was 2.3 (1.8). Fifty-four (75%) patients presented tendon damage of at least one tendon. From all evaluated tendons, 134 (46.5%) had no tendon damage, 146 (50.7%) had grade 1 and 8 (2.8%) had grade 2 tendon damage. The mean (s.d.) for RTS was 91.4 (97), for ERS was 47.3 (61.9) and for JSNS was 44.1 (37.2). We found a significant correlation between disease duration and both TDS and RTS (r = 0.413 and r = 0.560, respectively; P < 0.0001). We found a good significant correlation between TDS and all variables of radiographic structural damage (RTS, r = 0.65; ERS, r = 0.637; JSNS, r = 0.618; P < 0.001). CONCLUSION: The MSUS assessment of only four tendons can be an additional feasible method to assess structural damage in RA patients.

OBJECTIVES: Musculoskeletal ultrasound (MSUS) is an imaging technique increasingly used in paediatric rheumatology. The aim of our study was to evaluate the extent to which MSUS may influence the diagnosis and management decisions in daily clinical practice in paediatric rheumatology. METHODS: All child patients attending our PR unit over a 3-month period were included. A consultant rheumatologist assessed juvenile patients and weighted the need for MSUS assessment under a Likert scale from 0 (not necessary) to 5 (very necessary) with scanning performed when the Likert score was greater than 0. The rheumatologist completed a questionnaire used to report previous and current diagnosis, therapeutic decisions and disease activity. An assistant rheumatologist who was blinded to the questionnaire carried out the MSUS scanning of selected joints. After MSUS examination, a second questionnaire was completed by the consultant rheumatologist reporting changes in diagnosis and systemic and local treatment, if applicable. RESULTS: We included 111 patients [73 (65.8%) female]. Fifteen (13.5%) were new patients and 96 (86.5%) follow-up patients. Fifty-one (45.9%) patients were diagnosed with JIA. 65 (58.6%) patients qualified for MSUS. A total of 108 joints from 65 patients were clinically assessed with 93 (86.1%) joints deemed to require complementary MSUS assessment (mean assessed joints 1.4 per patient). Of the 65 patients undergoing MSUS, 38 (58.5%) patients there was a change in diagnosis, therapeutic decisions or both following the MSUS information. CONCLUSIONS: MSUS may play a significant role in local diagnosis and therapeutic decisions among follow-up JIA patients and could help in the management of rheumatic diseases in children. Further longitudinal studies are needed to confirm the impact of MSUS in paediatric rheumatology.

OBJECTIVE: The aim of this study was to investigate the influence of the pharmacokinetics of s.c. anti-TNF agents on the grade of US-detected synovitis in RA patients. METHODS: Fifty RA patients were prospectively recruited from the Biologic Therapy Unit of our hospital. Inclusion criteria were being in treatment with s.c. anti-TNF agents and having had neither changes in therapy nor local corticosteroid injections in the previous 3 months. Patients underwent clinical, laboratory [28-joint DAS (DAS28) and Simplified Disease Activity Index (SDAI)] and US assessment at two time points, i.e. at peak plasma drug concentration and at trough plasma drug concentration. US assessments were performed blindly to the anti-TNF agent, the administration time and the clinical and laboratory data. Twenty-eight joints were investigated for the presence and grade (0-3) of B-mode synovitis and synovial power Doppler signal. Global indices for B-mode synovitis (BSI) and Doppler synovitis (DSI) were calculated for 12 joints and for wrist-hand-ankle-foot joints. B-mode US remission was defined as a BSI <1 and Doppler US remission as a DSI <1. RESULTS: There were no significant differences between the clinical, laboratory and B-mode and Doppler US parameters at peak time and trough time (P = 0.132-0.986). There were no significant differences between the proportion of patients with active disease and those in remission according to DAS28, SDAI, B-mode US and Doppler US at peak time and trough time assessments (P = 0.070-1). CONCLUSION: Our results suggested that s.c. anti-TNF pharmacokinetics do not significantly influence US-scored synovitis in RA patients.

Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease uncommon in children, clinically characterized by recurrent parotitis at the onset, which is a common disorder in childhood, most of them of infectious origin. Juvenile pSS diagnosis is based on clinical symptoms and presence of autoantibodies, after exclusion of infectious or lymphoproliferative diseases. However, salivary gland ultrasound (SGU) shows typical features of pSS that can add useful information for the diagnosis of this disorder. We describe three patients who presented with recurrent parotitis in which characteristic autoantibodies and typical SGU pattern allow us to make the diagnosis of juvenile pSS. We suggest that in children with recurrent parotitis SGU and autoantibodies should be routinely performed.

OBJECTIVE: Understanding preferences of patients with rheumatoid arthritis (RA) can facilitate tailored patient-centric care. This study elicited trade-offs that patients with RA were willing to make during treatment selection. METHODS: Patients with RA completed an online discrete choice experiment, consisting of a series of choices between hypothetical treatments. Treatment attributes were selected based on literature review and qualitative patient interviews. Eligible patients were ≥18 years old, diagnosed with RA, receiving systemic disease-modifying antirheumatic drug therapy, and residents of Europe or USA. Male patients were oversampled for subgroup analyses. Data were analysed using a correlated mixed logit model. RESULTS: Of 2090 participants, 42% were female; mean age was 45.2 years (range 18-83). Estimated effects were significant for all attributes (p<0.001) but varied between patients. Average relative attribute importance scores revealed different priorities (p<0.001) between males and females. While reducing pain and negative effect on semen parameters was most important to males, females were most concerned by risk of blood clots and serious infections. No single attribute explained treatment preferences by more than 30%. Preferences were also affected by patients' age: patients aged 18-44 years placed less importance on frequency and mode of treatment administration (p<0.05) than older age groups. Patients were willing to accept higher risk of serious infections and blood clots in exchange for improvements in pain, daily activities or administration convenience. However, acceptable trade-offs varied between patients (p<0.05). CONCLUSION: Treatment preferences of patients with RA were individual-specific, but driven by benefits and risks, with no single attribute dominating the decision-making.

OBJECTIVE: To characterize and describe clinical experience with childhood-onset non-infectious uveitis. STUDY DESIGN: A multicenter retrospective multidisciplinary national web-based registry of 507 patients from 21 hospitals was analyzed. Cases were grouped as immune disease-associated (IMDu), idiopathic (IDIu) or ophthalmologically distinct. Characteristics of juvenile idiopathic arthritis-associated (non-HLA-B27-related) uveitis (JIAu), IDIu, and pars planitis (PP) were compared. RESULTS: IMDu (62.3%) and JIAu (51.9%) predominated in young females; and IDIu (22.7%) and PP (13.6%) in older children, without sex imbalance. Ocular complications occurred in 45.3% of cases (posterior synechiae [28%], cataracts [16%], band keratopathy [14%], ocular hypertension [11%] and cystoid macular edema [10%]) and were associated with synthetic (86%) and biologic (65%) disease-modifying antirheumatic drug (DMARD) use. Subgroups were significantly associated (p < 0.05) with different characteristics. JIAu was typically anterior (98%), insidious (75%), in ANA-positive (69%), young females (82%) with fewer complications (31%), better visual outcomes, and later use of uveitis-effective biologics. In contrast, IDIu was characteristically anterior (87%) or panuveitic (12.1%), with acute onset (60%) and more complications at onset (59%: synechiae [31%] and cataracts [9.6%]) and less DMARD use, while PP is intermediate, and was mostly bilateral (72.5%), persistent (86.5%) and chronic (86.8%), with more complications (70%; mainly posterior segment and cataracts at last visit), impaired visual acuity at onset, and greater systemic (81.2%), subtenon (29.1%) and intravitreal (10.1%) steroid use. CONCLUSION: Prognosis of childhood uveitis has improved in the "biologic era," particularly in JIAu. Early referral and DMARD therapy may reduce steroid use and improve outcomes, especially in PP and IDIu.
RESUMO
OBJECTIVE: To evaluate whether early treatment with methotrexate (MTX) prevents the onset of uveitis in children with juvenile idiopathic arthritis. STUDY DESIGN: The clinical charts of all consecutive patients seen between January 2002 and February 2011 who had a disease duration <1 year at first visit and had received a stable management for at least 2 years with or without MTX were reviewed. Patients who were given systemic medications other than MTX (except nonsteroidal anti-inflammatory drugs) were excluded. Patients with systemic arthritis, rheumatoid factor-positive arthritis, or enthesitis-related arthritis were also excluded. In each patient, the 2-year follow-up period after first visit was examined to establish whether uveitis had occurred. RESULTS: A total of 254 patients with a median disease duration of 0.3 year were included. Eighty-six patients (33.9%) were treated with MTX, whereas 168 patients (66.1%) did not receive MTX. During the 2-year follow-up, 211 patients (83.1%) did not develop uveitis, whereas 43 patients (16.9%) had uveitis a median of 1.0 year after the first visit. The frequency of uveitis was lower in MTX-treated than in MTX-untreated patients (10.5% vs 20.2%, respectively, P = .049). Survival analysis confirmed that patients treated with MTX had a lower probability of developing uveitis. CONCLUSION: Early MTX therapy may prevent the onset of uveitis in children with juvenile idiopathic arthritis. Because our study may be affected by confounding by indication, the potential of MTX to reduce the incidence of ocular disease should be investigated in a randomized controlled trial.

Idiopathic recurrent pericarditis (IRP) is defined by 2 or more episodes of acute pericarditis of unknown etiology. Either auto-immune or auto-inflammatory diseases are suspected. Usually, non-steroidal anti-inflammatory drugs, colchicine or low dose steroid treatments are effective, however, side effects and/or non-response patients are frequent. We report on three paediatric patients with IRP from our paediatric rheumatology unit. The patients were non-responders to standard therapy and were treated with tumour necrosis factor alpha blocking agents (anti-TNF-α) and showed significant improvement. In two patients, the treatment was tapered and then stopped following several years of therapy. Symptoms flared in the last patient when therapy was tapered more quickly. We conclude that anti-TNF-α can be useful in selected cases of IRP.

OBJECTIVE: The goal of juvenile idiopathic arthritis (JIA) treatment is to maintain clinical remission. It is also important to reduce drug exposure, whenever possible, in order to avoid or decrease potential side effects. We aimed to analyze remission survival after systemic treatment withdrawal and to determine which factors can influence it. METHODS: We conducted a multicenter, observational, longitudinal study. All patients included had a diagnosis of JIA. We analyzed remission survival using Kaplan-Meier curves according to the systemic treatment received (methotrexate [MTX] alone or in combination with biologic disease-modifying antirheumatic drugs [bDMARDs]) and JIA subgroups (oligoarticular and polyarticular course, juvenile spondyloarthritis, and systemic JIA). In addition, risk factors were examined using multivariate analysis. RESULTS: We included 404 patients with JIA; 370 of them (92%) had received systemic treatment at some point and half of them (185 patients) had withdrawn on at least 1 occasion. There were 110 patients who flared (59%) with a median time of 2.3 years. There were no differences in remission survival between JIA subcategories. Twenty-nine percent of patients with JIA who received MTX and bDMARDs, in which MTX alone was withdrawn, flared; median time to flare of 6.3 years. However, if only the bDMARD was withdrawn, flares occurred 57% of the time; median time to flare of 1.1 years. CONCLUSION: Flares are frequent when systemic treatment is withdrawn, and uveitis or joint injections could be related risk factors. In MTX and biologic-naïve patients, the frequency of flares occurred in more than half of patients, although they were less frequent when clinical remission lasted for > 1 year.

OBJECTIVE: To analyse factors involved in the decision to optimise biologics in juvenile idiopathic arthritis. METHODS: A "discrete-choice" methodology was used. In a nominal group meeting, factors which may influence physicians' decisions to optimise biological dose were identified, together with decision nodes. 1000Minds® was used to create multiple fictitious clinical scenarios based on the factors identified, and to deploy surveys that were sent to a panel of experts. These experts decided for each item which of two clinical scenarios prompted them to optimise the dose of biologic. A conjoint analysis was carried out, and the partial-value functions and the weights of relative importance calculated. RESULTS: In the nominal group, three decision nodes were identified: (1) time to decide; (2) to maintain/reduce or prolong interval; (3) what drug to reduce. The factors elicited were different for each node and included patient and drug attributes. The presence of macrophage activation syndrome (MAS), systemic involvement, or subclinical inflammation made the decision easier (highest weights). The presence of joints of difficult control and year of debut influenced the decision in some but not all, and in different directions. Immunogenicity, adherence, and concomitant treatments were also aspects taken into account. CONCLUSIONS: The decision to optimise the dose of biological therapy in children and youngster can be divided into several nodes, and the factors, both patient and therapy-related, leading to the decision can be detailed. These decisions taken by experts may be transported to practice, study designs, and guidelines.

BACKGROUND: Salivary gland ultrasound (SGU) provides information about structural gland abnormalities that can be graded and used for primary Sjögren's syndrome (pSS) diagnosis. Its potential role as a prognostic marker for detecting patients at high risk of lymphoma and extra-glandular manifestations is still under evaluation. We aim to assess the usefulness of SGU for SS diagnosis in routine clinical practice and its relationship with extra-glandular involvement and lymphoma risk in pSS patients. METHODS: We designed a retrospective observational single-center study. Data was collected using the electronic health records of patients referred to an ultrasound outpatient clinic for evaluation over a 4-year period. Data extraction included demographics, comorbidities, clinical data, laboratory tests, SGU results, salivary gland (SG) biopsy, and scintigraphy results. Comparisons were made between patients with and without pathological SGU. The external criterion for comparison was the fulfillment of the 2016 ACR/EULAR pSS criteria. RESULTS: A total of 179 SGU assessments were included from this 4-year period. Twenty-four cases (13.4%) were pathological. The most frequently diagnosed conditions prior to SGU-detected pathologies were pSS (9.7%), rheumatoid arthritis (RA) (13.1%), and systemic lupus (4.6%). One hundred and two patients (57%) had no previous diagnosis (sicca syndrome work-up); of these, 47 patients (46.1%) were ANA positive and 25 (24.5%) anti-SSA positive. In this study, the sensitivity and specificity of SGU for SS diagnosis were 48% and 98% respectively, with a positive predictive value of 95%. There were statistically significant relationships between a pathological SGU and the presence of recurrent parotitis (p=.0083), positive anti-SSB antibodies (p=.0083), and a positive sialography (p=.0351). CONCLUSIONS: SGU shows high global specificity but low sensitivity for pSS diagnosis in routine care. Pathological SGU findings are associated with positive autoantibodies (ANA and anti-SSB) and recurrent parotitis.

OBJECTIVES: JAK kinase inhibitors (JAKi) are a new therapeutic option in the treatment of rheumatoid arthritis, but they are not without risks, especially the incidence of herpes zoster (HZ). MATERIAL AND METHODS: Systematic literature review that evaluates the incidence of HZ published in the clinical trials of the different JAK is marketed or under study. RESULTS: The HZ rates ranged between 1.51 and 20.22. The results were expressed mainly as a percentage of events. The most recent studies better categorized the incidence of HZ and its severity. CONCLUSION: JAK is are associated with an increased risk of HZ. Although the HZ rates of the selective JAK1 JAK is are lower, more studies are needed to confirm these results.

OBJECTIVE: To evaluate the impact of cardiovascular risk (CVR) on the diagnostic accuracy of the ultrasonographic (US) Halo Score in patients with suspected giant cell arteritis (GCA). METHODS: Retrospective observational study of patients referred to our US fast track clinic with suspected GCA for a 2-year period. The intima-media thickness (IMT) of cranial and extra-cranial arteries and the Halo Score was determined to assess the extent of vascular inflammation. The European Society of Cardiology Guidelines on CV Disease Prevention were used to define different categories of CVR and patients were classified according to the Systemic Coronary Risk Evaluation (SCORE). The gold standard for GCA diagnosis was clinical confirmation after a 6-month follow-up. RESULTS: Of the 157 patients included, 47 (29.9%) had GCA after a 6-month follow-up. Extra-cranial artery IMT was significantly higher in patients with high/very high CVR than in those with low/moderate CVR, but only among patients without GCA. Non-GCA patients with high/very high CVR had also a significantly higher Halo Score in contrast with low/moderate CVR [9.38 (5.93) vs 6.16 (5.22); p = 0.007]. The area under the ROC curve of the Halo Score to identify GCA was 0.835 (95% CI 0.756-0.914), slightly greater in patients with low/moderate CVR (0.965 [95% CI 0.911-1]) versus patients with high/very high CVR (0.798 [95% CI 0.702-0.895]). A statistically weak positive correlation was found between the Halo Score and the SCORE (r 0.245; c = 0.002). CONCLUSIONS: Elevated CVR may influence the diagnostic accuracy of the US Halo Score for GCA. Thus, CVR should be taken into consideration in the US screening for GCA.

Objective: To determine the optimal ultrasound (US) cut-off values for cranial and extracranial arteries intima media thickness (IMT) to discriminate between patients with and without giant cell arteritis (GCA). Methods: Retrospective observational study including patients referred to an US fast-track clinic. All patients underwent bilateral US examination of the cranial and extracranial arteries including the IMT measurement. Clinical confirmation of GCA after 6 months was considered the gold standard for diagnosis. A receiver operating characteristic (ROC) analysis was performed to select the cut-off values on the basis of the best tradeoff values between sensitivity and specificity. Results: A total of 157 patients were included, 47 (29.9%) with clinical confirmation of GCA after 6 months. 41 (87.2%) of patients with GCA had positive US findings (61.7% had cranial and 44.7% extracranial involvement). The best threshold IMT values were 0.44 mm for the common temporal artery; 0.34 mm for the frontal branch; 0.36 mm for the parietal branch; 1.1 mm for the carotid artery and 1 mm for the subclavian and axillary arteries. The areas under the ROC curves were greater for axillary arteries 0.996 (95% CI 0.991-1), for parietal branch 0.991 (95% CI 0.980-1), for subclavian 0.990 (95% CI 0.979-1), for frontal branch 0.989 (95% CI 0.976-1), for common temporal artery 0.984 (95% CI 0.959-1) and for common carotid arteries 0.977 (95% CI 0.961-0.993). Conclusion: IMT cut-off values have been identified for each artery. These proposed IMT cut-off values may help to improve the diagnostic accuracy of US in clinical practice.
RESUMO
OBJECTIVE: To determine the usefulness of power Doppler (PD) ultrasound (US) to predict rheumatoid arthritis (RA) development in patients with clinically suspect arthralgia (CSA). METHODS: Retrospective analysis of a US unit cohort over a 1-year period. Patients with CSA and no previous diagnosis of inflammatory arthritis (IA) were included for analysis. All underwent bilateral US examination of the hands and/or feet according to the EULAR guidelines. Active US inflammation was defined as PD synovitis and/or tenosynovitis ≥1 at any location. RA diagnosis according to clinician criteria 6 months after the US examination was checked. Univariate and multivariate logistic regression models were employed to investigate possible predictive factors of RA development. RESULTS: A total of 110 CSA patients (80 females, mean age 53.6 years) were included for analysis. After 6 months of follow-up, 14 (12.7%) developed RA and 34 (30.9%) IA. US active inflammation was present in 38 (34.5%) patients (28.2% showed PD synovitis and 18.2% PD tenosynovitis). Multivariate analysis showed that ACPA (OR 1.0003; 95% CI 1.002-1.006) and ESR (OR 1.054; 95% CI 1.016-1.094) were significantly associated with the detection of US active inflammation at baseline. Only PD tenosynovitis was found to be an independent predictive factor of an evolution towards RA (OR 6.982; 95% CI 1.106-44.057) and IA (OR 5.360; 95% CI 1.012-28.390). CONCLUSION: US is able to detect features of subclinical inflammation in CSA patients, especially in those with higher ESR and ACPA values. Only PD tenosynovitis at baseline US assessment was found to be an independent predictor of RA and IA development in CSA patients.
