Impaired muscle strength is associated with ultrastructure damage in myositis.

The muscle fiber ultrastructure in Idiopathic Inflammatory Myopathies (IIM) has been scarcely explored, especially in Inclusion Body Myositis. The aim of this study was to implement the Scanning Electron Microscopy (SEM) in a small cohort of IIM patients, together with the characterization of immunological profile for a better understanding of the pathophysiology. For immunological profile characterization, we identified the presence of autoantibodies (Ro-52, OJ, EJ, PL7, PL12, SRP, Jo-1, PMScl75, PMScl100, Ku, SAE1, NXP2, MDA5, TIF1γ, Mi-2α, Mi-2β) and quantified cytokines (IL-1β, IFN-α2, IFN-γ, TNF-α, IL-6, IL-10, IL-12p70, IL-17A, IL-18, IL-23, IL-33) and chemokines (CCL2, CXCL8).

Addressing health disparities as a function of ethnicity in systemic lupus erythematosus patients.

Systemic lupus erythematosus (SLE) is an autoimmune disorder with significant health disparities, as it disproportionately and more severely affects vulnerable and disadvantaged population groups in the United States and around the world, that is, women, ethnic minorities, individuals living in poverty, less educated, and lacking medical insurance. Both, genetic and non-genetic factors, contribute to these disparities. To overcome these health disparities and reduce poor outcomes among disadvantaged SLE populations, interventions on non-genetic amendable factors, especially on social health determinants, are necessary.

Going Further: Comprehensive Disease Control of Rheumatoid Arthritis, Targeting Cytokines and Chemokines.

Material And Methods: A group of 15 experts in SpA translated, analyzed and modified the recommendations of the Mexican College of Rheumatology (CMR) and the International Society for the Assessment of Spondyloarthritis (ASAS)/European League Against Rheumatism (EULAR) 2016 group through a systematic review of the literature by two external reviewers during the period from 2015 to 2018 using the grade of recommendation, Oxford levels of evidence, percentage of concordance (Delphi).

Results: Compared to previous recommendations, there were no significant changes from the year 2015.

IgG Anti-ghrelin Immune Complexes Are Increased in Rheumatoid Arthritis Patients Under Biologic Therapy and Are Related to Clinical and Metabolic Markers.

Rheumatoid arthritis (RA) is a systemic autoimmune disease associated with increased risk of cardiovascular disease and metabolic alterations. The mechanisms underlying these alterations remain unclear. Ghrelin is a gastrointestinal hormone with potent effects on food intake, body weight, metabolism, and immune response.

Subclinical parameters of arterial stiffness and arteriosclerosis correlate with QRISK3 in systemic lupus erythematosus.

Unlabelled: It is well known that cardiovascular diseases (CVD) are a major contributor of death in systemic lupus erythematosus (SLE) as well in other rheumatic illness. In the last decades, there has been a growing development of different methodologies with the purpose of early detection of CVD.

Objective: The aim of this study is to correlate the usefulness of subclinical parameters of vascular aging and QRISK 3-2017 score for early detection of CVD in SLE.

Disease Activity Score on 28 Joints and Polypharmacy Are Independent Predictors for Health-Related Quality of Life Evaluated by INCAVISA in Patients With Rheumatoid Arthritis.

Low levels of CD36 in peripheral blood monocytes in subclinical atherosclerosis in rheumatoid arthritis: a cross-sectional study in a Mexican population.

Unlabelled: Patients with rheumatoid arthritis (RA) have a higher risk for atherosclerosis. There is no clinical information about scavenger receptor CD36 and the development of subclinical atherosclerosis in patients with RA. The aim of this study was to evaluate the association between membrane expression of CD36 in peripheral blood mononuclear cells (PBMC) and carotid intima-media thickness (cIMT) in patients with RA.

Beyond the joints: neurological involvement in rheumatoid arthritis.

Although arthritis is the most notable component, rheumatoid arthritis (RA) is a systemic inflammatory disorder where extra-articular manifestations are common; among them, central and peripheral nervous system involvement is frequent and associated with significant morbidity and, in some cases, reduced life span. It may produce a myriad of symptoms and signs ranging from subtle numbness in a hand, to quadriparesis and sudden death. Central and peripheral neurologic manifestations may arise from structural damage produced by RA in diarthroidal joints, by the systemic inflammatory process of the disease itself or by the drugs used to treat it.

[Anti-transglutaminase, antigladin and ultra purified anti-gladin antibodies in patients with a diagnosis of rheumatoid arthritis].

Unlabelled: Celiac disease (CD) is an enteric disease caused by dietary gluten in individuals with genetic predisposition. One of the clinical manifestations of CD is the peripheral arthritis that may simulate RA.

Objective: To determine the frequency of anti-gliadin (aGL), anti-tissue transglutaminase (aTGT) and ultra purified anti-gliadin (AGLU) antibodies in patients with RA.

Fifteen-year trends of long-term disability and sick leaves in ankylosing spondylitis.

The aim of this study is to assess the trends in work disability and sick leave in ankylosing spondylitis (AS). In 1993 and 2007, patients diagnosed with AS that attended to a secondary- or a tertiary-care outpatient rheumatology clinics were evaluated for demographics, disease characteristics, axial mobility, working status, and work days missed due to sick leave or permanent disability. Factors that impacted labor status were identified by multiple regression analysis.

Tendinous and ligamentous derangements in systemic lupus erythematosus.

Objective: We assessed the prevalence of selected clinical and radiological features of tendinous and ligamentous derangements in a consecutive sample of patients with systemic lupus erythematosus (SLE).

Methods: Consecutive patients with SLE with no comorbidities attending a tertiary care center were prospectively assessed and underwent plain radiographic evaluation of the pelvis. Radiographs were analyzed by 2 blinded observers; radiographic sacroiliitis was graded 0 to IV.

The heart-joints connection: atherosclerosis and inflammation.

Advances in basic and clinical sciences have established the role of inflammation in the pathogenesis of atherosclerosis. Endothelial dysfunction is the initial event, which is followed by lipid oxidation, atheroma formation and rupture, as well as the formation of a thrombus, leading to a clinical event. A decreased survival due to accelerated atherosclerosis in patients with rheumatic diseases has been demonstrated; this cannot be fully explained by traditional cardiovascular risk factors, suggesting that disease-related factors are also operative.
