Salivary gland ultrasound in clinical practice: What is its real usefulness?

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.

Clinical Characteristics of Juvenile Idiopathic Inflammatory Myopathy and Comparison With Adult Patients: Analysis From a Multicentric Cohort in Spain.

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.

Long-Term Retention Rate of Golimumab in Patients With Rheumatoid Arthritis, Psoriatic Arthritis, and Spondyloarthritis in a Real-Life Setting.

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.

Estado actual del tratamiento con infiltraciones intraarticulares en la artritis idiopática juvenil / Intra-articular joint injections in juvenile idiopathic arthritis: state of the art

Objetivo: Las infiltraciones intraarticulares con corticoides (IAC) son parte fundamental en el tratamiento de la artritis idiopática juvenil. Se realiza una revisión sobre la situación actual de las IAC en población infantil. Métodos: Revisión narrativa de la literatura de las IAC en población infantil, relacionada con la técnica de infiltración, el uso de anestesia local y general, la guía ecográfica, las indicaciones, las articulaciones especiales y el tipo de corticoide. Resultados: Las IAC están indicadas en cualquier subcategoría de artritis idiopática juvenil y especialmente en la forma oligoarticular. El uso de anestésico local es recomendable, y en pacientes menores de 6 años o que requieran infiltración múltiple, también la sedación consciente. La infiltración guiada por ecografía es recomendable en manos expertas, pero no de forma generalizada. El hexacetónido de triamcinolona es el corticoide de elección en articulaciones grandes, mientras corticoides más solubles (betametasona o metilprednisolona) serían la alternativa ideal en articulaciones pequeñas o superficiales para evitar la atrofia subcutánea o la hipopigmentación, los efectos adversos más frecuentes. Conclusiones: Las IAC se realizan de forma heterogénea y la evidencia científica es limitada

Objective: Intra-articular corticosteroid injections (IACI) are a fundamental part in the treatment of juvenile idiopathic arthritis. The current situation of IACI is reviewed in a population of children. Methods: We conducted a narrative review of the literature related to IACI in children, with respect to the injection technique, use of local and general anesthesia, ultrasound guidance of the procedure, indications, special joints and type of optimal corticosteroid. Results: IACI are indicated in any subcategory of juvenile idiopathic arthritis, especially in oligoarticular juvenile idiopathic arthritis. The use of local anesthetic is highly recommended, and in patients younger than 6 years or requiring multiple joint injections, conscious sedation can also be an option. Ultrasound guidance of injections is recommended in expert hands, but not in a generalized way. Triamcinolone hexacetonide is the corticosteroid of choice in large joints, whereas a more soluble corticosteroid is a better alternative in small or superficial joints (betamethasone or methylprednisolone) to avoid subcutaneous atrophy or hypopigmentation, the most frequent adverse effect of IACI. Conclusions: IACI are performed heterogeneously and scientific evidence is limited in many cases

The beliefs of rheumatoid arthritis patients in their subcutaneous biological drug: strengths and areas of concern.

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.

Identifying markers of sustained remission in rheumatoid arthritis patients on long-term tapered biological disease-modifying antirheumatic drugs.

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.

An exploratory study to determine whether infliximab modifies levels of rheumatoid factor and antibodies to cyclic citrullinated peptides in rheumatoid arthritis patients.

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.

A total of 479 patients were recruited in the REMICAM registry of inflammatory myopathies. Including sociodemographic, clinical and prognostic information, it represents the largest Spanish multicenter registry to date in rheumatology, and constitutes an important source for conducting further substudies (AU)

Identification of patients at risk of non-adherence to oral antirheumatic drugs in rheumatoid arthritis using the Compliance Questionnaire in Rheumatology: an ARCO sub-study.

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.

Non-adherence to subcutaneous biological medication in patients with rheumatoid arthritis: a multicentre, non-interventional study.

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.
