Diagnosis of latent tuberculosis infection in patients with immune-mediated inflammatory chronic diseases (IMIDs) can be challenged as diagnostic test reliability could be impaired by immunosuppression. We retrospectively analyzed the Quantiferon Gold-Test in-Tube (QFT-G-IT) results of all patients with IMIDs seen at the Department of Internal Medicine of Son Llàtzer Hospital, Palma de Mallorca (Spain), looking for the factors related to QFT-G-IT indeterminate results. During the study period (2008-2015), 520 patients met the inclusion criteria. Factors associated with indeterminate QFT-G-IT results in a univariate analysis were inflammatory bowel disease, disease activity, lymphopenia, and medium-to-high doses of corticosteroids. In a subsequent multivariate analysis, only lymphopenia (defined as < 1500 cells) was associated with indeterminate QFT-G-IT results. Lymphocyte count was the only factor independently associated with an increased number of indeterminate QFT-G-IT results in patients with different autoimmune diseases. Others factors such as the use of medium-to-high doses of corticosteroids should be considered before testing with QFT-G-IT. [ABSTRACT FROM AUTHOR]

Complete heart block (CHB) is a rare complication of systemic lupus erythematosus (SLE), mainly seen during an acute flare-up of the disease or after high-dose long-term treatment with antimalarial drugs, although anti-Ro and anti-RNP antibodies have also been implied by some authors. A 40-y-old woman developed CHB in the context of an acute flare-up of SLE, first diagnosed three years ago, having recently commenced hydroxychloroquine (HCQ) treatment. Anti-Ro and anti-RNP antibodies were also positive. No features of myocarditis were found. A temporary pacemaker was required and complete resolution was achieved on steroid therapy with withdrawal of antimalarial therapy. The characteristics of previous cases are well publicised and discussion focuses on the possible aetiology and pathogenesis of the present case. [ABSTRACT FROM AUTHOR]

Objective: To determine the prevalence and predictive factors of cerebrovascular accidents (CVA) in giant cell arteritis (GCA)., Methods: ARTESER is a large Spanish multicentre registry including patients with GCA from across the entire country diagnosed between June 2013 and March 2019 and sponsored by the Spanish Society of Rheumatology. The variables collected at diagnosis were demographics, clinical manifestations (including the occurrence and location of CVA), laboratory, histology and imaging findings. Patients with and without CVA were compared in a bivariate analysis. Multivariate logistic regression was performed to determine potential predictive factors of CVA., Results: A total of 1540 patients with GCA were included for analysis (mean age 77.1 years, 70% females). CVA occurred in 61 (3.96%), of whom 38 (62.3%) involved the vertebrobasilar territory and 21 (34.4%) the carotid territory. The factors associated with CVA were the occurrence of transient ischaemic attack (TIA) (OR 8.63; 95% CI 2.877-25.86), large vessel (LV) involvement (OR 2.79; 95% CI 1.421- 5.465) and the presence of concomitant visual manifestations (OR 2.73; 95% CI 1.427-5.235). The risk of death during follow-up was significantly higher in patients with CVA (18% vs 8.8%; p= 0.014). Patients with CVA received significantly higher mean prednisone (mg) dose at diagnosis (433.9 vs 216; p< 0.001) and cumulative prednisone dose during follow-up (11 203.9 vs 8,194.1; p< 0.001)., Conclusion: The prevalence of CVA in patients with GCA is low, but increases the risk of mortality. The presence of TIA, LV involvement and visual manifestations are factors associated with increased risk of CVA., (© The Author(s) 2025.

Objective: To assess the incidence of serious infection (SI) and associated factors in a large juvenile-onset systemic lupus erythematosus (jSLE) retrospective cohort., Methods: All patients in the Spanish Rheumatology Society Lupus Registry (RELESSER) who meet ≥4 ACR-97 SLE criteria and disease onset <18 years old (jSLE), were retrospectively investigated for SI (defined as either the need for hospitalization with antibacterial therapy for a potentially fatal infection or death caused by the infection). Standardized SI rate was calculated per 100 patient years. Patients with and without SI were compared. Bivariate and multivariate logistic and Cox regression models were built to calculate associated factors to SI and relative risks., Results: A total of 353 jSLE patients were included: 88.7% female, 14.3 years (± 2.9) of age at diagnosis, 16.0 years (± 9.3) of disease duration and 31.5 years (±10.5) at end of follow-up. A total of 104 (29.5%) patients suffered 205 SI (1, 55.8%; 2-5, 38.4%; and ≥6, 5.8%). Incidence rate was 3.7 (95%CI: 3.2-4.2) SI per 100 patient years. Respiratory location and bacterial infections were the most frequent. Higher number of SLE classification criteria, SLICC/ACR DI score and immunosuppressants use were associated to the presence of SI. Associated factors to shorter time to first infection were higher number of SLE criteria, splenectomy and immunosuppressants use., Conclusions: The risk of SI in jSLE patients is significant and higher than aSLE. It is associated to higher number of SLE criteria, damage accrual, some immunosuppressants and splenectomy., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Background: Treatment compliance with disease-modifying antirheumatic drugs (DMARD) is essential to achieve the therapeutic goals in rheumatoid arthritis (RA). However, despite the need for good compliance, there is evidence that patients with RA frequently fail to use DMARD for the control of RA. Thus, the main objective of the OBSERVAR study is to evaluate the reasons for the lack of therapeutic adherence to synthetic DMARD in these patients., Patients and Methods: A Delphi process involving 18 randomly selected Spanish rheumatologists determined the level of agreement with 66 causes of noncompliance selected from the literature in relation to synthetic DMARD in RA., Results: The reasons for noncompliance were consistent in 75.7%, although 3 reasons (4.5%) were highly consistent: 1) not knowing what to do in the case of an adverse event with DMARD; 2) not having undergone adherence screening by health personnel for early detection of "noncompliant patients"; and 3) not having undergone interventions or strategies that improve adherence., Conclusion: In order to improve adherence to RA treatment with synthetic DMARD, the patient should be adequately informed of each new treatment introduced, the patient's compliance profile should be incorporated into the clinical routine and the patient's motivation for therapeutic compliance be reinforced through the methods available to us., (Copyright © 2017 Elsevier España, S.L.U. and Sociedad Española de Reumatología y Colegio Mexicano de Reumatología.

Objectives: To determine the incidence and risk factors of first cardiovascular event (CVE) in patients with chronic inflammatory rheumatic diseases (CIRD)., Methods: Analysis of data after 2.5 years of follow-up from the prospective study CARMA project, that includes patients with CIRD [rheumatoid arthritis (RA), ankylosing spondylitis (AS), and psoriatic arthritis (PsA)] and matched individuals without CIRD from 67 hospitals in Spain. CVE cumulative incidence per 1000 patients was calculated after 2.5 years from the start of the project. Weibull proportional hazard model was used to calculate hazard ratio (HR) and 95% confidence interval (95% CI) of the risk factors., Results: 2595 (89.1%) patients completed the 2.5 years of follow-up visit. Cumulative incidence of CVE in patients with CIRD was 15.30 cases per 1000 patients (95% CI: 12.93-17.67), being higher in the subgroup with AS; 22.03 (95% CI: 11.01-33.04). Patients with AS (HR: 4.11; 95% CI: 1.07-15.79), those with older age (HR: 1.09; 95% CI: 1.05-1.13), systolic hypertension (HR: 1.02; 95% CI: 1.00-1.04) and long duration of the disease (HR: 1.07; 95% CI: 1.03-1.12) were at higher risk of first CVE during the 2.5 years of follow-up. In contrast, female gender was a protective factor (HR: 0.43; 95% CI: 0.18-1.00)., Conclusions: Among CIRD patients prospectively followed-up at rheumatology outpatient clinics, those with AS show higher risk of first CVE. Besides cardiovascular risk factors, such as hypertension, being a man and older as well as having a long disease duration increase the risk of CVE in patients with CIRD.

Objective: To investigate the prevalence, clinical characteristics and prognosis of pulmonary arterial hypertension (PAH) in adult onset Still's disease (AOSD)., Methods: We retrospectively reviewed all patients with AOSD diagnosed during a 33-year period in 2 referral tertiary care hospitals, selecting for analysis those who presented PAH confirmed as by right heart catheterization. A systematic review of the literature (PubMed 1990 to July 2018) was also performed, in order to determine the prognosis and the most appropriate treatment strategy for this complication., Results: The overall prevalence of PAH in our AOSD population was 4.8% (2/41). Including our 2 cases, 20 well-documented patients have been reported. PAH may complicate AOSD at any time during its course, and usually occurs in patients who have persistent and severe disease, with a considerable frequency (35%) of previous or concomitant severe clinical complications. In all cases, the etiology of pulmonary hypertension was a group 1 PAH based on the 2015 ESC/ERS guidelines. Most patients in this series had advanced WHO functional classes III-IV at the time of PAH diagnosis, reflecting an important diagnostic delay. Thirty-three percent of patients had a poor outcome despite the therapy, with a mortality rate that reached 22%. The therapeutic strategy that achieved the best results was the use of glucocorticoids, immunosuppression and PAH-specific vasodilator therapy., Conclusion: HAP is an under-recognized complication of AOSD that should be kept in mind in the differential diagnosis of those patients who experience dyspnea on exertion or a decrease in exercise tolerance., (Copyright © 2018 Elsevier Inc.

Aims: To describe the methodology of the EPISER 2016 (study of the prevalence of rheumatic diseases in adult population in Spain), as well its strengths and limitations. The aim of this study is to estimate the prevalence of rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), systemic lupus erythematosus (SLE), Sjögren's syndrome (SS), osteoarthritis (knee, hip, hands, and cervical and lumbar spine), fibromyalgia, gout and clinical osteoporotic fracture., Material and Method: Population-based, multicenter, cross-sectional study, with the participation of 45 municipalities in the 17 Spanish autonomous communities. The reference population will consist of adults aged 20 years and over residing in Spain. A computer-assisted telephone interview (CATI) system will be used for data collection. Diagnostic suspicions and diagnoses received by the participants will be studied by rheumatologists in the referral hospitals in the selected municipalities., Statistical Analysis: the prevalence of the rheumatic diseases will be calculated using estimators and their 95% confidence intervals. Weights will be calculated in each of the sampling stages in accordance with the probability of selection. The distribution of the population in Spain will be obtained from the Spanish Statistics Institute., Conclusions: Sociodemographic and lifestyle changes over the last 16 years justify EPISER 2016. This study will provide current data about the prevalences of RA, AS, PsA, SLE, SS, osteoarthritis, fibromyalgia, gout and clinical osteoporotic fracture. The results will allow comparisons with studies from other countries and EPISER 2000., (Copyright © 2017 Elsevier España, S.L.U. and Sociedad Española de Reumatología y Colegio Mexicano de Reumatología.

CD8-positive γδ T lymphocytes (GDCD8(+)) are specifically increased in peripheral blood of Behçet's disease (BD) patients. GDCD8(+) have shown a T regulatory (Treg) function in autoimmune experimental models, human tumor infiltrates and intestinal intraepithelial lymphocytes from celiac patients. The aim of this study was to evaluate the Treg function of GDCD8(+) and GDCD8(-), freshly isolated from peripheral blood, in comparison to CD4(+)CD25(high) naturally occurring Treg cells (nTreg) in BD and healthy controls (HC). We tested their suppressive activity on CD4(+)CD25(-) T effector cells (Teff) proliferation by a CFSE dilution protocol, after suboptimal activation with anti-CD3, in the absence or presence of IL-2. Furthermore, secreted cytokines and suppressive latency associated peptide (LAP)-TGFβ surface upregulation were determined after GD activation. We found that Vδ1 chains contribution to GDCD8(+) was higher in BD than in HC, but neither GDCD8(+) nor GDCD8(-); (i) suppressed Teff proliferation, (ii) expressed LAP-TGFβ (iii) nor secreted IL-10, in either group. Moreover, GD presented a proinflammatory cytokine profile, mainly producing IFNγ and TNFα, in contrast to nTregs. In conclusion, peripheral GD could contribute more to the dysregulation of TH1 type of cytokines than to exerting a Treg function in BD., (Copyright © 2015 American Society for Histocompatibility and Immunogenetics.

Lipoma arborescens is a rare intraarticular lesion characterized by diffuse replacement of the subsynovial tissue by mature fat cells, producing villous transformation of the synovium. The etiology of this benign condition is unknown. The most typical site of involvement is the knee, most notably at the suprapatellar pouch, although other joints can be affected. Symptoms consist of gradual joint swelling, variable pain, motion range restriction, and intermittent joint effusions or bleeding. We report a case of lipoma arborescens and discuss the clinical features, diagnosis, and treatment of this disorder based on a literature review. Although it is rare, lipoma arborescens should be included in the differential diagnosis of patients with chronic joint swelling or hemarthrosis.
