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., (Copyright © 2022 Elsevier España, S.L.U. and Sociedad Española de Reumatología y Colegio Mexicano de Reumatología.

Objective: To prevent the deterioration of patients with fibromyalgia due to potentially avoidable harmful actions in clinical practice., Methods: A multidisciplinary panel of experts identified key areas, analysed the scientific evidence and formulated recommendations based on this evidence and qualitative techniques of "formal assessment" or "reasoned judgement"., Results: Thirty-nine recommendations were made on diagnosis, ineffective and unsafe treatments, patient education and practitioner training. This part II shows the 12 recommendations, referring to the latter two areas., Conclusions: Good knowledge of fibromyalgia on the part of patients improves their coping and acceptance of the disease and reduces the severity of some clinical manifestations. Healthcare professionals treating patients with fibromyalgia should be well trained in this disease to improve treatment outcomes and patient relationships., (Copyright © 2021 Elsevier España, S.L.U. and Sociedad Española de Reumatología y Colegio Mexicano de Reumatología.

Objective: To prevent the impairment of fibromyalgia patients due to harmful actions in daily clinical practice that are potentially avoidable., Methods: A multidisciplinary team identified the main areas of interest and carried out an analysis of scientific evidence and established recommendations based on the evidence and "formal evaluation" or "reasoned judgment" qualitative analysis techniques., Results: A total of 39 recommendations address diagnosis, unsafe or ineffective treatment interventions and patient and healthcare workers' education. This part I shows the first 27 recommendations on the first 2 areas., Conclusions: Establishing a diagnosis improves the patient's coping with the disease and reduces healthcare costs. NSAIDs, strong opioids and benzodiazepines should be avoided due to side effects. There is no good evidence to justify the association of several drugs. There is also no good evidence to recommend any complementary medicine. Surgeries show a greater number of complications and a lower degree of patient satisfaction and therefore should be avoided if the surgical indication is not clearly established., (Copyright © 2021 Elsevier España, S.L.U. and Sociedad Española de Reumatología y Colegio Mexicano de Reumatología.

Objectives: To assess the plasma apolipoprotein B/apolipoprotein A1 ratio and its potential association with cardiovascular events (CVE) in patients with rheumatoid arthritis (RA)., Methods: A baseline analysis was made of the CARdiovascular in rheuMAtology Project (CARMA), a 10-year prospective study evaluating the presence of at least one CVE in 775 Spanish patients with RA. Of them, 29 had already experienced CVE prior to the inclusion in the study. We assessed the association between the elevation of the apoB/apoA1 ratio with the presence of CVE according to a logistic regression model for possible confounding factors. We also analysed the main parameters of activity of RA and parameters related to lipid metabolism. RA patients were classified according to treatment: patients treated with disease-modifying anti-rheumatic drugs without biologics and those undergoing biologic therapy (anti-TNF-α, anti-IL-6 receptor, and other biologic agents)., Results: The apoB/apoA1 ratio of patients who had experienced CVE was higher than that of patients without previous CVE (0.65 vs. 0.60). However, the difference between both subgroups did not reach statistical significance (p=0.197). It was also the case after the multivariate analysis [OR: 1.48 (95% CI: 0.15-14.4); p=0.735]. RA patients from the group with CVE were more commonly receiving lipid-lowering treatment with statins than those without CVE history (41.4% vs. 20%, p=0.005). High HAQ and high atherogenic index were significantly associated with the presence of CVE. There was no statistical association between the type of biologic therapy used in RA and the presence of CVE., Conclusions: No association between ApoB/apoA1 ratio and CVE was found at the baseline visit of patients with RA from the CARMA study.

Chronic fatigue syndrome is characterised by intense fatigue, with duration of over six months and associated to other related symptoms. The latter include asthenia and easily induced tiredness that is not recovered after a night's sleep. The fatigue becomes so severe that it forces a 50% reduction in daily activities. Given its unknown aetiology, different hypotheses have been considered to explain the origin of the condition (from immunological disorders to the presence of post-traumatic oxidative stress), although there are no conclusive diagnostic tests. Diagnosis is established through the exclusion of other diseases causing fatigue. This syndrome is rare in childhood and adolescence, although the fatigue symptom per se is quite common in paediatric patients. Currently, no curative treatment exists for patients with chronic fatigue syndrome. The therapeutic approach to this syndrome requires a combination of different therapeutic modalities. The specific characteristics of the symptomatology of patients with chronic fatigue require a rapid adaptation of the educational, healthcare and social systems to prevent the problems derived from current systems. Such patients require multidisciplinary management due to the multiple and different issues affecting them. This document was realized by one of the Interdisciplinary Work Groups from the Institute for Rare Diseases, and its aim is to point out the main social and care needs for people affected with Chronic Fatigue Syndrome. For this, it includes not only the view of representatives for different scientific societies, but also the patient associations view, because they know the true history of their social and sanitary needs. In an interdisciplinary approach, this work also reviews the principal scientific, medical, socio-sanitary and psychological aspects of Chronic Fatigue Syndrome.

Objective: To develop guidelines for the appropriate use of NSAIDs in rheumatology., Methods: We used a methodology modified from the one developed by RAND/UCLA. Two groups of panellists were selected, one by the CMR and another by the SER. Recommendations were proposed from nominal groups and the agreement to them was tested among rheumatologists from both societies by a tworound Delphi survey. The analysis of the second Delphi round supported the generation of the final set of recommendations and the assignment of a level of agreement to each of them. Systematic reviews of five recommendations in which the agreement was low or was divided were also carried out., Results: Here we present recommendations for the safe use of NSAIDs in rheumatic diseases, based on the best available evidence, expert opinion, the agreement among rheumatologists, and literature review. The trend is to reduce the frequency, duration and dose of NSAIDs in favour of non-pharmacological measures, analgesic drugs or disease modifying drugs. In addition, the recommendations help to identify profiles for increased toxicity, with an emphasis on gastrointestinal and cardiovascular risks. The recommendations deal with the course of action and monitoring in different risk groups and in patients using antiplatelet or anticoagulant drugs. The overall level of agreement is high., Conclusions: The NSAIDs are safe and effective drugs for the treatment of rheumatic diseases. However, it is necessary to individualize its use according to their risk profile., (Copyright © 2009 Elsevier España S.L. Barcelona. Published by Elsevier Espana. All rights reserved.)

Objective: To obtain an updated FIQ consensus version for patients in Spain, the Cuestionario de Impacto de la Fibromialgia (CIF)., Material and Methods: The CIF elaboration was carried out with the participation of all the groups of researchers in the 4 previous FIQ Spanish versions, and taking into account the recent updated version of the original FIQ. The CIF was completed by a sample of fibromialgia patients to explore how comprensible its items are and to compare its global score with 2 fibromialgia composite severity indexes, one semi-objective and one subjective. The corresponding Spearman correlation coefficients were determined, Results: The main modifications introduced in the questionnaire are shown. Some patients were confused in their responses to subitem "j" and item 3, but not with regard to the remaining items or subitems. Correlation coeficients between the CIF and the semi-objective and subjective fibromialgia severity indexes were 0.57 and 0.76 respectively (P<001)., Conclusion: The CIF is proposed as an updated Spanish version of the FIQ., (Copyright © 2007 Elsevier España S.L Barcelona.

Reflex sympathetic dystrophy syndrome (RSDS) is a rare entity of unknown etiopathogenesis, associated to different precipitating factors such as malignant tumors of several localizations. A new clinical variety has been recently described which has been denominated palmar fasciitis and polyarthritis syndrome. We present here two patients with RSDS associated to breast cancer: one case presenting fasciitis and polyarthritis and another case also associated to polymyalgia rheumatica. We emphasize the importance of reducing the tumor mass in the treatment of this syndrome, as well as including it in the gammagraphic differential diagnosis of bone metastasis.
