Novel biomarkers in RA: Implication for diagnosis, prognosis, and personalised treatment.

Over the past decades our understanding of rheumatoid arthritis (RA) pathogenesis has improved remarkably and major breakthroughs in the treatment of RA were made with the advent of numerous targeted therapies and new treatment strategies. Despite these advances, several unmet needs remain, namely in achieving earlier and more accurate diagnosis, monitoring disease activity, predicting disease prognosis and optimizing treatment. To address these gaps, recent research has focused on identifying biomarkers that may enhance diagnostic precision, predict disease prognosis, and optimize treatment strategies.

Impaired Periodontitis-Induced Cytokine Production by Peripheral Blood Monocytes and Myeloid Dendritic Cells in Patients with Rheumatoid Arthritis: A Case-Control Study.

: Immune cells from rheumatoid arthritis (RA) patients display a reduced in vitro response to (), which may have functional immune consequences. The aim of this study was to characterize, by flow cytometry, the frequency/activity of monocytes and naturally occurring myeloid dendritic cells (mDCs) in peripheral blood samples from patients with periodontitis and patients with periodontitis and RA. : The relative frequency of monocytes and mDCs in the whole blood, the frequency of these cells producing TNFα or IL-6 and the protein expression levels for each cytokine, before and after stimulation with lipopolysaccharide (LPS) from plus interferon-γ (IFN-γ), were assessed by flow cytometry, in peripheral blood samples from 10 healthy individuals (HEALTHY), 10 patients with periodontitis (PERIO) and 17 patients with periodontitis and RA (PERIO+RA).

Association Between Visual Acuity and Prospective Fall Risk in Generally Healthy and Active Older Adults: The 3-Year DO-HEALTH Study.

Objective: Although aging has a strong impact on visual acuity (VA) and falls, their interaction is understudied in generally healthy older adults. This study aimed to examine if and to what extent baseline VA is associated with an increased risk of all and injurious falls over 3 years in generally healthy community-dwelling older adults.

Design: Observational analysis of DO-HEALTH, a double-blind, randomized controlled trial.

Happiness, quality of life and their determinants among people with systemic sclerosis: a structural equation modelling approach.

Background: Patients' objectives and experiences must be core to the study and management of chronic diseases, such as SSc. Although patient-reported outcomes are attracting increasing attention, evaluation of the impact of disease on the overall subjective well-being, equivalent to 'happiness', is remarkably lacking.

Objectives: To examine the determinants of happiness and quality of life in patients with SSc, with emphasis on disease features and personality traits.

Immunomodulatory effect of human bone marrow-derived mesenchymal stromal/stem cells on peripheral blood T cells from rheumatoid arthritis patients.

Rheumatoid arthritis (RA) is a Th1/Th17-mediated autoimmune disease whose current treatment, consisting in the blockage of inflammatory cytokines by disease-modifying antirheumatic drugs, is not effective for all patients. The therapeutic potential of mesenchymal stromal/stem cells' (MSCs) immunomodulatory properties is being explored in RA. Here, we investigate the effect of human bone marrow (BM)-MSCs on the expression of cytokines involved in RA physiopathology by the distinct functional compartments of CD4 and CD8 T cells from RA patients.

The many faces of IgG4-related disease: report of a case with inaugural recurrent aortic aneurism ruptures and literature review.

Vascular involvement in IgG4-related disease (IgG4-RD), is a well-recognized feature and large vessel commitment, especially the aorta, can be the only manifestation of the disease. Being a newly recognized disease, its diagnosis and workup still represents a challenge in clinical practice. A 47-year-old-man with two aortic aneurysms ruptures, one at abdominal and the other at thoracic level, was referred to our rheumatology department.

Invalidation in Patients with Rheumatic Diseases: Clinical and Psychological Framework.

Objective: The term "invalidation" refers to the patients' perception that their medical condition is not recognized by the social environment. Invalidation can be a major issue in patients' lives, adding a significant burden to symptoms and limitations while increasing the risk of physical and psychological disability. In this study in patients with rheumatic diseases, we investigated the relationship between invalidation and sociodemographic, clinical, psychological, and personality characteristics.

A preliminary study using virtual touch imaging and quantification for the assessment of skin stiffness in systemic sclerosis.

Objectives: To evaluate ultrasound Virtual Touch Imaging and Quantification (VTIQ) as a method for determining absolute skin stiffness in patients with systemic sclerosis (SSc).

Methods: Skin thickness, assessed by the modified Rodnan Skin Score (mRSS) and absolute skin stiffness, using VTIQ, were measured at all mRSS anatomical sites to quantify the shear wave velocity (in m/s) in 26 SSc patients and in 17 age- and gender-matched controls. Correlations between mRSS and absolute skin stiffness, and comparisons between patients and controls were analysed statistically using Mann-Whitney U tests and correlations between variables using Pearson's.

Topical NSAIDs for chronic musculoskeletal pain in adults.

Background: Use of topical nonsteroidal anti-inflammatory drugs (NSAIDs) to treat chronic musculoskeletal conditions has become widely accepted because they can provide pain relief without associated systemic adverse events. This review is an update of 'Topical NSAIDs for chronic musculoskeletal pain in adults', originally published in Issue 9, 2012.

Objectives: To review the evidence from randomised, double-blind, controlled trials on the efficacy and safety of topically applied NSAIDs for chronic musculoskeletal pain in adults.

Cost-Effectiveness of Intervention Thresholds for the Treatment of Osteoporosis Based on FRAX(®) in Portugal.

Cost-effective intervention thresholds (ITs) based on FRAX(®) were determined for Portugal. Assuming a willingness to pay (WTP) of €32,000 per quality-adjusted life years (QALYs), treatment with generic alendronate is cost effective for men and women aged 50 years or more, with 10-year probabilities for major osteoporotic fractures and hip above 8.8 and 2.

TRAF1/C5 but not PTPRC variants are potential predictors of rheumatoid arthritis response to anti-tumor necrosis factor therapy.

Background: The aim of our work was to replicate, in a Southern European population, the association reported in Northern populations between PTPRC locus and response to anti-tumor necrosis factor (anti-TNF) treatment in rheumatoid arthritis (RA). We also looked at associations between five RA risk alleles and treatment response.

Methods: We evaluated associations between anti-TNF treatment responses assessed by DAS28 change and by EULAR response at six months in 383 Portuguese patients.

Safety of glucocorticoids in rheumatoid arthritis: evidence from recent clinical trials.

Glucocorticoids are one of the most effective treatments for rheumatoid arthritis, with well-established efficacy in controlling the disease symptoms and structural progression. Fears regarding their toxicity are reflected in common recommendations for the use of the lowest possible dose for the shortest possible time. We herein review toxicity data obtained in randomized clinical trials of low-dose glucocorticoid in rheumatoid arthritis, given that observational studies cannot guarantee the avoidance of bias by indication.

Safety of low- to medium-dose glucocorticoid treatment in rheumatoid arthritis: myths and reality over the years.

Low- to medium-dose glucocorticoids have been shown to have not only anti-inflammatory but also disease-modifying properties in rheumatoid arthritis. The evidence for the benefit of its early use in combination with disease-modifying antirheumatic drugs underlines the need for a close evaluation of their risk-benefit ratio. Over time, numerous myths and fears about glucocorticoid toxicity in rheumatoid arthritis have arisen from observational studies, and many concerns have been unduly extrapolated from observations with higher-dose treatment.

Identification of clinical predictors of flare in systemic lupus erythematosus patients: a 24-month prospective cohort study.

Objective: SLE has a relapsing-remitting course with disease activity flares over time. This study aims to identify clinical predictors of SLE flares.

Methods: This prospective cohort study over 24 months included all SLE patients on follow-up at one academic lupus clinic.

Developing a professional approach to work-based assessments in rheumatology.

This chapter discusses how doctors in key European countries develop and maintain professional standards of clinical knowledge in their specialism, rheumatology, with particular reference to how they are assessed in the workplace. The authors discuss key educational theories related to learning and assessment, including experiential learning, reflective practice, how formative and summative assessments drive experiential learning and the essential principles of reliability and validity. This chapter also considers the challenge of ensuring that professional attitudes towards assessment and reflective practice are developed alongside cognitive and practical skills, with reference to current frameworks, including the UK and North America.

Rheumatology education in Europe: results of a survey of young rheumatologists.

Objectives: To evaluate the level of education and participation in an internship abroad and to European league against rheumatism (EULAR) on line course of young rheumatologists. To define new tools for learning.

Methods: Questionnaires were administered to 170 trainees and young specialists in 2008-2009 during official EULAR meetings or using the mailing list of European young rheumatologists in training.

Applying science in practice: the optimization of biological therapy in rheumatoid arthritis.

Most authorities recommend starting biological agents upon failure of at least one disease-modifying agent in patients with rheumatoid arthritis. However, owing to the absence of head-to-head studies, there is little guidance about which biological to select. Still, the practicing clinician has to decide.

Effects of testosterone, 17beta-estradiol, and downstream estrogens on cytokine secretion from human leukocytes in the presence and absence of cortisol.

Estrogens at physiological concentrations are thought to play an immune-stimulating role, whereas androgens have an anti-inflammatory impact. However, their role on cytokine secretion in the presence or absence of cortisol has not been investigated. Furthermore, the role of hydroxylated estrogens downstream of 17beta-estradiol (E2) on secretion of tumor necrosis factor (TNF) is not known.

Soft tissue injections.

Soft tissue rheumatism includes a wide spectrum of common lesions of the tendons, enthesis, tendon sheaths, bursae, ligaments and fasciae as well as nerve compression syndromes. Studies on the pathogenesis of these lesions do not support a major role for inflammation, thus questioning the rationale for glucocorticoid injections. This chapter reviews current indications for local glucocorticoid injections and available evidence on its efficacy, as well as contraindications and potential risks.

Relationships between glucocorticoids and gonadal steroids in rheumatoid arthritis.

Gender and sex hormones are strongly related to the incidence and progression of autoimmune rheumatic diseases. Although sex steroids have been shown to have direct effects on the immune system, their influence in vivo may be mediated via interactions with third party systems including the hypothalamic-pituitary-adrenal axis. Such interactions are well demonstrated in experimental animals.

Differential male and female adrenal cortical steroid hormone and cortisol responses to interleukin-6 in humans.

Evidence from experimental animal studies show that sex hormones influence the glucocorticoid response to a variety of inflammatory and noninflammatory stimuli. In this study we assessed gender differences in the response of ACTH and cortisol in normal young male and female humans following intravenous infusion of human IL-6 in various dosages. Males presented a significantly stronger ACTH production in response to IL-6 than females.
