RESUMO
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.

METHODS: This study reviewed the medical records of patients from the REMICAM cohort, a multicentric longitudinal study carried out in patients with IIM, followed up between 1980 and 2014 in 12 hospitals in Madrid, Spain. Patients with definite or probable JPM, JDM, adult DM, and adult PM according to the modified Bohan and Peter criteria were selected. We compared the characteristics between JDM and JPM, and between JIIM and adult IIM. RESULTS: Eighty-six juvenile patients (75 JDMs and 11 JPMs) and 283 adult patients (133 DMs and 150 PMs) were included. Compared with patients with JDM, patients with JPM were older at diagnosis, had more fever and arthritis, and were less frequently treated with disease-modifying antirheumatic drugs (these differences were not statistically significant). Compared with patients with adult DM, those with JDM presented more frequently with calcinosis (33.8% vs 6.9%, p < 0.0001) and had less severe infections (4.3% vs 23.4%, p < 0.0001), malignancies (1.3% vs 25.6%, p < 0.0001), and mortality (3.5% vs 33%, p < 0.0001). Patients with JDM were treated less frequently with azathioprine (10.8% vs 44.7%, p < 0.0001). CONCLUSIONS: Our findings confirm that JIIMs are a heterogeneous group of diseases with relevant differences compared with adult IIMs.

OBJECTIVES: The aim of this study was to investigate the relationship between serum infliximab (IFX) levels and changes of RF and ACPA levels in patients with rheumatoid arthritis (RA). METHODS: Enzyme-linked immunosorbent assays (ELISA) [Promonitor® IFX R1 (version 2) (Progenika Biopharma, Spain)] were used to measure drug levels and antidrug-antibodies (ADAb) in IFX RA-treated patients (n=19). Disease activity was assessed using DAS28. IgM rheumatoid factor (RF) and IgM, IgA and IgG anti-cyclic citrullinated peptide (ACPA) were determined through ELISA. RESULTS: A significant decrease in RF (p=0.01), ACPA IgG (p=0.007), IgM (p=0.01) and IgA (p=0.03) was observed in patients presenting adequate levels of serum IFX. No significant changes to RF or ACPA were observed in patients with undetectable IFX. CONCLUSIONS: Data from this study support the hypothesis that the anti-TNF antagonist IFX downregulates autoantibody levels in RA patients when IFX levels are detectable. Larger-scale studies need to be performed to establish RF and ACPA presence as therapeutic response predictive factors.

Patients' beliefs about their prescribed medication are an important factor influencing intentional non-adherence. This study describes rheumatoid arthritis (RA) patients' beliefs about their subcutaneous (SC) biological medication through the Beliefs about Medicines Questionnaire (BMQ), and potential associations. As part of the ARCO study (Study on Adherence of Rheumatoid arthritis patients to subCutaneous and Oral drugs), patients completed the BMQ specifically for their SC biological medication, encompassing a necessity and a concerns scale. The medication possession ratio (MPR) was calculated to assess adherence to the SC biological medication. The BMQ was completed by 321 patients. Between 71.0 and 89.7% of patients agreed/strongly agreed with necessity scale statements, and only 7.2% had low necessity scores. Between 20.0 and 49.8% of patients agreed/strongly agreed with four of five concern scale statements, and 72.3% agreed/strongly agreed with the concern statement regarding long-term medication effects. The percentage with high concerns was 58.9%, and was higher in patients not satisfied with, or with less fulfillment of, tolerability expectations. Non-adherence percentages were, respectively, 13.8 and 13.0% (p = 0.919) in those with high or low necessity, and 16.0 and 10.6% (p = 0.171) in those with high or low concerns. Most patients were categorized as 'ambivalent' (58.5%; high necessity/high concerns) or 'accepting' (36.1%; high necessity/low concerns) of their SC biological medication. The BMQ identified patients' concerns with their SC biological medication. Because patients' concerns could influence non-adherence to medication and future outcomes, physicians should address this issue in the clinic by informing patients and setting clear expectations.

RESUMO
To identify features associated with long-term persistent remission in rheumatoid arthritis (RA) patients on tapered biological disease-modifying antirheumatic drugs (bDMARD) (tap-bDMARD) therapy. We carried out a 40-month (m) extension follow-up study of 77 RA patients from a previous 12 m tap-bDMARD study. Disease activity was assessed at baseline and every 3 months. Doppler US investigation of 42 joints for the presence and grade (0-3) of B-mode synovial hypertrophy (SH) and synovial power Doppler signal (i.e., Doppler synovitis) was performed before starting the tap-bDMARD strategy by a rheumatologist blinded to clinical and laboratory data. At the 40 m mark, 44 (57.1%) patients failed the tap-bDMARD strategy, while 33 (42.9%) succeeded. Patients who presented a failed tap-bDMARD had significantly longer disease duration, a longer time from symptom onset to synthetic (s) DMARD start, longer duration of sDMARD treatment, a greater number of sDMARDs, and a higher baseline DAS28 and SDAI than patients with successful tap-bDMARD at 40 months. In logistic regression analysis, the presence of baseline Doppler synovitis, a DAS28 ≥ 2.2, and the presence of rheumatoid factor were identified as predictors of tap-bDMARD failure at 40 m. In those patients who succeed tap-bDMARD at 12 m, a smoking habit was significantly more frequently found in tap-bDMARD failures at 40 m. Our results showed that DAS28 and the presence of Doppler synovitis, RF and a smoking habit predicted long-term tap-bDMARD failure.

OBJECTIVES: To evaluate non-adherence to prescribed subcutaneous biologicals in rheumatoid arthritis (RA) patients in Spain. METHODS: ARCO (Study on Adherence of Rheumatoid Arthritis patients to SubCutaneous and Oral Drugs) was a multicentre, non-interventional retrospective study involving 42 rheumatology clinics from representative hospitals throughout Spain. The primary objective was to assess the percentage of patients (aged ≥18 years with an established RA diagnosis) with non-adherence to prescribed subcutaneous biologicals using clinical records and hospital pharmacy dispensing logs as the primary information sources. Adherence was assessed using the Medication Possession Ratio (MPR). Additionally, patients completed the Morisky-Green Medication Adherence Questionnaire. RESULTS: A total of 364 patients (77.5% females, mean age 54.9 years, median RA duration since diagnosis 7.8 years) were enrolled in ARCO. Non-adherence (MPR ≤80%) was reported in 52/363 evaluable patients (14.3%), and was lower in patients receiving initial monthly drug administration (6.4%) than with weekly (17.4%; p=0.034) or every two weeks (14.4%; p=0.102) administration. By multivariate analysis, non-adherence was positively associated with RA duration above the median and with using induction doses. Monthly administration, compared to weekly administration, was inversely associated with non-adherence. Age, gender, order of administration, and changes in the interval of administration, showed no association with non-adherence. Compared with the MPR, the Morisky-Green questionnaire performed poorly in detecting non-adherence. CONCLUSIONS: Non-adherence to the prescribed subcutaneous biological drug occurred in 14.3% of patients with RA. Patients using the most convenient administration period (i.e. monthly) had better adherence than those using more frequent dosing schedules.

The ARCO study (Study on Adherence of Rheumatoid Arthritis patients to SubCutaneous and Oral Drugs), a multicenter, non-interventional retrospective study, was primarily designed to assess the percentage of patients [aged ≥18 years with an established rheumatoid arthritis (RA) diagnosis] with non-adherence to prescribed subcutaneous biologicals. This paper reports data for the secondary objective from a subset of patients, namely to evaluate non-adherence to prescribed oral antirheumatic drugs in RA patients in Spain using the validated Compliance Questionnaire Rheumatology (CQR). Patients also completed the Morisky-Green Medication Adherence Questionnaire, Beliefs about Medicines Questionnaire, and a questionnaire (developed and validated in Spain) on patient satisfaction with RA treatment and preferences. A total of 271 patients (76.7% females; mean age 55.6 years) were being treated with oral drugs for RA, of which 234 completed the CQR questionnaire. Non-adherence was reported in 49/234 (20.9%) patients. The proportion of non-adherence in younger patients (aged ≤48 years; 37.5%) was double that recorded in patients aged >48 years (p = 0.006). Patients with a perception of lower efficacy also had a higher risk of non-adherence (p = 0.012). Multivariable analysis showed that younger age and male gender were independently associated with risk of non-adherence. There was only slight agreement between the CQR and Morisky-Green assessment tools (kappa coefficient = 0.186), possibly reflecting the fact that both questionnaires measure slightly different aspects of medication adherence. In conclusion, one out of five RA patients was identified as at risk for non-adherence with the CQR, and this was more frequent in younger patients and in males.

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: To investigate the presence of biomechanical abnormalities and ultrasound (US)-detected inflammation and damage in low disease or remission status rheumatoid arthritis (RA) patients with foot complaints. METHODS: We recruited 136 subjects with foot complaints. Sixty-two were biologic disease-modifying antirheumatic drug-treated RA patients presenting Disease Activity Score-determined remission or low disease activity while the remaining 74 were gender matched controls without rheumatic or musculoskeletal disorders. Both groups underwent a comprehensive podiatric, biomechanical and B-mode and Doppler US assessment of the feet. RESULTS: Most RA patients and controls were female (77.4% and 83.8%, respectively). There was no statistical difference in the proportion of obese subjects in either group (p=0.792). Inappropriate shoes were used by 50.0% of RA patients and 33.8% of controls (p=0.080). Talalgia, particularly heel pain, was more frequent in the control group, with associated talalgia and metatarsalgia being more prevalent in the RA group (p<0.05). The RA patient group was also more likely to present greater foot deformity, more limited joint movement and biomechanical abnormalities than the controls (p<0.05). US inflammatory and structural changes were significantly more frequent in RA patients than in controls (p<0.05). US structural involvement was significantly associated with limited joint mobility and pathologic biomechanical tests only in RA patients (p<0.05). CONCLUSIONS: RA foot complaints seemed to be linked to US-detected RA involvement and biomechanical abnormalities. Podiatric and US assessments can be useful to help the clinician to optimise the management of RA patients in remission/low disease activity with foot complaints.

OBJECTIVES: To evaluate biomechanical and ultrasound (US) abnormalities in SLE patients as compared with controls and to assess the relationship between these abnormalities and SLE activity. METHODS: Fifty-four consecutive female patients with SLE with and without foot pain and 60 female controls (30 with foot pain and 30 without foot pain) were recruited. SLE activity was assessed by the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). SLE patients and controls blindly underwent a comprehensive podiatric, biomechanical and US evaluation of the feet. US assessment included detection of B-mode synovitis, tenosynovitis, enthesopathy, bone changes and synovial, tenosynovial and entheseal power Doppler (PD) signal. RESULTS: Thirty-one (57.4%) SLE patients had bilateral foot pain and 5 (9.3%) had unilateral foot pain. Metatarsalgia was the most common location for pain but without significant difference between groups (p=0.284). Toe joint deformities were significantly more common in SLE feet as compared with control feet (p<0.0005). SLE feet showed significantly more biomechanical abnormalities than control feet (p<0.05). B-mode synovitis in the tibiotalar joint was strongly associated with having SLE (p<0.0005) and the presence of synovial PD signal in the MTP joints was found only in painful feet of SLE patients. SLEDAI was significantly higher in patients with foot pain than in those with painless feet (p=0.008). However, SLEDAI did not discriminate between patients with and without biomechanical or US abnormalities. CONCLUSIONS: SLE patients showed more biomechanical and US abnormalities in the feet than controls, which were not captured by standardised assessment of the disease activity.

This cross-sectional observational study aimed to explore the relationship between B cell count and ultrasound (US)-detected synovitis, in patients with rheumatoid arthritis treated with rituximab. Thirty-seven consecutive RA patients treated with RTX were recruited for the study. The patients underwent clinical [i.e., Disease Activity Score 28 joints (DAS28)], laboratory, and US assessment of 12 joints. Each joint was semiquantitatively (0-3) scored on B-mode and power Doppler mode. The scores were summed, and a global index was created for BM (BMS) and PD scores (PDI) synovitis. BM subclinical synovitis was evident in all patients, with PD synovial signal detected in 16 patients (43.2 %). No correlation was found between DAS28 and US scores. B cells were detected in 27 (72.9 %) patients, but there was no association in the mean B cell count and disease activity as measured by DAS28 (DAS28 < 2.6 = 34.53, DAS28 > 2.6 = 49.45, p = 0.52) and PDI score (PDI < 1 = 49.48, PDI > 1 = 35.44, p = 0.54). There was no correlation between the B cell count and DAS28, BMS, and PDI (r = 0.020, p = 0.907; r = -0.151, p = 0.371; r = -0.099, p = 0.558, respectively). In RTX-treated RA patients, no relationship could be established between US-detected synovitis and peripheral blood B cell count.

The aim of the study was to investigate the predictive value of different reduced joint ultrasound (US) assessments of synovitis and tenosynovitis in relation to unstable remission in a cohort of rheumatoid arthritis (RA) patients on methotrexate therapy. Forty-seven RA patients (38 women, 9 men), being treated with methotrexate (MTX), in clinical remission as judged by their consultant rheumatologist were evaluated for disease activity according to the Disease Activity Score (DAS) 28 at baseline and 6 months. Sustained remission and unstable remission were defined according to the baseline and 6-month DAS28 and changes in RA therapy during the follow-up. Each patient underwent at baseline a B-mode and power Doppler (PD) assessment of 44 joints and 20 tendons/tendon compartments by a rheumatologist blinded to the clinical and laboratory data. B-mode synovial hypertrophy (SH), synovial PD signal, B-mode tenosynovitis, and Doppler tenosynovitis were scored 0-3. The presence and index of synovial PD signal in 44 joints [odds ratio (OR) 8.21 (p = 0.016) and OR 2.20 (p = 0.049), respectively] and in 12 joints [OR 5.82 (p = 0.041) and OR 4.19 (p = 0.020), respectively], the presence of SH in wrist and MCP joints [OR 4.79 (p = 0.045)], and the presence of synovial PD signal in wrist-MCP-ankle-MTP joints [OR 4.62 (p = 0.046)] were predictors of unstable remission. The 12-joint or wrist-hand-ankle-MTP US assessments can predict unstable remission in RA patients in apparent clinical remission being treated with MTX.

OBJECTIVE: To investigate the predictive value of synovitis detected by Doppler US in relation to failed tapering of biologic therapy (BT) in RA patients in sustained clinical remission. METHODS: A total of 77 RA patients (52 women, 25 men) in sustained clinical remission, treated with a stable dosage of BT were prospectively recruited. BT was tapered according to an agreed strategy implemented in clinical practice (i.e. increasing the interval between doses for s.c. BT and reducing the dose for i.v. BT). BT tapering failure was assessed at 6 and 12 months. Doppler US investigation of 42 joints for the presence and grade (0-3) of B-mode synovial hypertrophy and synovial power Doppler signal (i.e. Doppler synovitis) was performed at baseline by a rheumatologist blinded to clinical and laboratory data. Hand and foot radiographs were obtained at baseline and at 12-month follow-up. RESULTS: Of the 77 patients, 46 (59.7%) were on s.c. BT and 31 (40.3%) on i.v. BT. At 12 months, 35 patients (45.5%) presented BT tapering failure, 23 of them (29.9% of all patients) in the first 6 months of BT tapering. In logistic regression analysis, the baseline DAS28 and the global score of Doppler synovitis were identified as independent predictors of BT tapering failure at 12 and 6 months. The presence of Doppler synovitis was the strongest predictor for BT tapering failure. No patient showed radiographic progression. CONCLUSION: Our results suggest that the presence of Doppler-detected synovitis may predict BT tapering failure in RA patients in sustained clinical remission.

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.

OBJECTIVES: The complement system plays a fundamental role in mediating the activity of rheumatoid arthritis (RA). Biologic therapy can reduce native complement component levels and its activation. We aimed to study the relation of Doppler ultrasound (US) synovitis versus clinical synovitis with changes in native complement component levels in RA patients on biologic therapy. METHODS: This was a cross-sectional study. Ninety-seven consecutive patients with RA on biologic therapy for at least 3 months were recruited. Clinical, laboratory and Doppler US assessments were performed. The Disease Activity Score in 28 joints (DAS28), Simplified Disease Activity Index (SDAI) and a 12-joint US assessment were carried out. Synovitis was semiquantitatively scored in B-mode and power Doppler (PD) mode. RESULTS: A significant decrease in native complement (i.e. C3 and C4) and C-reactive protein (CRP) levels was observed. This was highly significant for C3 decrease (p<0.0005), and C4 decrease (p<0.0005). Synovitis detected by PD US showed significant negative association with C3 change (p<0.008), where patients with higher C3 change were more likely to have PD US inactive status on assessment. CONCLUSIONS: Our results suggested that disease inactive status determined by PD US but not by clinical assessment can be related with decrease in complement in RA patients treated with biologic therapy.

There are various immunosorbent assays which can be used to determine infliximab (IFX) levels. Results vary between assays complicating reliability in everyday clinical practice. The aim of this study was to determine whether quantitative or qualitative assay data prove more accurate in the assessment of infliximab levels in AS patients. We analyzed 40 serum samples, taken prior to infusion, from AS patients who had been undergoing IFX therapy as a first-line of biological treatment for more than a year. IFX levels and IFX-anti-drug antibodies (ADA) were measured using two different ELISA assays [Promonitor IFX R1 and R2 (version 1), Promonitor IFX and anti-IFX (version 2) (Progenika Biopharma, Spain)] strictly following the manufacturer's guidelines. Cohen's unweighted kappa and the intraclass correlation coefficient determined qualitative and quantitative agreement for serum levels in version 1 and version 2. Bland-Altman plots were drawn to compare both assays. The comparison of data measuring IFX levels for version 1 and version 2 resulted in questionable quantitative agreement (ICC 0.659; 95% CI 0.317-0.830) and moderate qualitative agreement (κ 0.607; 95% CI 0.387-0.879) owing to systematically higher values in version 2 than version 1. Version 2 consistently detected higher levels of infliximab, particularly when analyzed in a quantitative context. Further research is needed to synchronize cutoff levels between essays and diseases so therapeutic drug ranges can be established.

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.

Over the last decade, there has been a growing body of evidence on the validity of Doppler ultrasound for assessing inflammatory changes in target anatomic structures involved in rheumatic diseases such as joints, tendons, entheses and vessels. The enhanced sensitivity for detecting low-velocity flow in synovium vessels achieved by current Doppler techniques has lead to the incorporation of Doppler US in the assessment of joint and inflammatory enthesis lesions. This review offers an overview of the key aspects of current applications and limitations of Doppler ultrasound in inflammatory rheumatic diseases. The basic principles of Doppler modes, Doppler scanning method, and Doppler artefacts and pitfalls in rheumatology ultrasound are also described.

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.
