Pathogenesis of polymyalgia rheumatica

2018

Polymyalgia rheumatica (PMR) is a chronic, inflammatory disorder of unknown cause, almost exclusively occurring in people aged over 50 and often associated with giant cell arteritis. The evidence that PMR occurs almost exclusively in individuals aged over 50 may indicate that age-related immune alterations in genetically predisposed subjects contribute to development of the disease. Several infectious agents have been investigated as possible triggers of PMR even though the results are inconclusive. Activation of the innate and adaptive immune systems has been proved in PMR patients as demonstrated by the activation of dendritic cells and monocytes/macrophages and the altered balance betwee…

Association of low 25-hydroxyvitamin D concentrations with elevated parathyroid hormone concentrations and low cortical bone density in early puberta…

2003

Background: Very few studies have evaluated both parathyroid hormone (PTH) and 25-hydroxyvitamin D [25(OH)D] and their effects on bone mass in children. Objective: We studied the associations of serum 25(OH)D and intact PTH (iPTH) with bone mineral content (BMC) and bone mineral density (BMD) at different bone sites and the relation between serum 25(OH)D and iPTH in early pubertal and prepubertal Finnish girls. Design: The subjects were 10‐12-y-old girls (n = 193) at Tanner stage 1 or 2, who reported a mean (± SD) dietary calcium intake of 733 ± 288 mg/d. 25(OH)D, iPTH, tartrate-resistant acid phosphatase 5b (TRAP 5b), urinary calcium excretion, BMC, areal BMD, and volumetric BMD were asses…

Dissecting the clinical heterogeneity of adult-onset Still's disease, results from a multi-dimensional characterisation and stratification

2021

Abstract Objectives To stratify adult-onset Still’s disease (AOSD) patients in distinct clinical subsets to be differently managed, by using a multi-dimensional characterization. Methods AOSD patients were evaluated by using a hierarchical unsupervised cluster analysis comprising age, laboratory markers systemic score and outcomes. The squared Euclidean distances between each pair of patients were calculated and put into a distance matrix, which served as the input clustering algorithm. Derived clusters were descriptively analysed for any possible difference. Results Four AOSD patients clusters were identified. Disease onset in cluster 1 was characterized by fever (100%), skin rash (92%) an…

Inhibition of xanthine oxidase to prevent statin-induced myalgia and rhabdomiolysis

2015

Although statins remain the cornerstone of lipid-lowering therapy for reducing the burden of atherosclerotic vascular disease, their administration has been associated with muscle-related adverse effects, including myalgia and rhabdomyolysis. Such adverse events are probably due to reduced antioxidant defenses associated with fewer intermediate metabolites in the cholesterol synthesis pathway. We hypothesize that the concomitant inhibition of xanthine oxidase via coadministration of allopurinol with statins could diminish reactive oxygen species (ROS)-related muscle damage, which would have in turn have positive effects on both the incidence of muscle-related adverse events and cardiovascul…

Analysis of vitamin D levels in patients with and without statin-associated myalgia — A systematic review and meta-analysis of 7 studies with 2420 pa…

2014

article i nfo Introduction: VitaminD (vitD)deficiencymay beassociatedwith anincreased riskof statin-related symptomatic myalgia in statin-treated patients. The aim of this meta-analysis was to substantiate the role of serum vitamin D levels in statin-associated myalgia. Methods: The search included PUBMED, Cochrane Library, Scopus, and EMBASE from January 1, 1987 to April 1, 2014 to identify studies that investigated the impact of vit D levels in statin-treated subjects with and without myalgia. Two independent reviewers extracted data on study characteristics, methods and outcomes. Quantita- tive data synthesis was performed using a fixed-effect model. Results: The electronic search yielde…

The impact of Nordic walking on bone properties in postmenopausal women with pre-diabetes and non-alcohol fatty liver disease

2021

This study investigated the impact of Nordic walking on bone properties in postmenopausal women with pre-diabetes and non-alcohol fatty liver disease (NAFLD). A total of 63 eligible women randomly participated in the Nordic walking training (AEx, n = 33), or maintained their daily lifestyle (Con, n = 30) during intervention. Bone mineral content (BMC) and density (BMD) of whole body (WB), total femur (TF), femoral neck (FN), and lumbar spine (L2-4) were assessed by dual-energy X-ray absorptiometry. Serum osteocalcin, pentosidine, receptor activator of nuclear factor kappa-B ligand (RANKL) levels were analyzed by ELISA assay. After an 8.6-month intervention, the AEx group maintained their BM…

Electroencephalography as a Non-Invasive Biomarker of Alzheimer’s Disease: A Forgotten Candidate to Substitute CSF Molecules?

2021

Biomarkers for disease diagnosis and prognosis are crucial in clinical practice. They should be objective and quantifiable and respond to specific therapeutic interventions. Optimal biomarkers should reflect the underlying process (pathological or not), be reproducible, widely available, and allow measurements repeatedly over time. Ideally, biomarkers should also be non-invasive and cost-effective. This review aims to focus on the usefulness and limitations of electroencephalography (EEG) in the search for Alzheimer’s disease (AD) biomarkers. The main aim of this article is to review the evolution of the most used biomarkers in AD and the need for new peripheral and, ideally, non-invasive b…

Impact of intermittent energy restriction on anthropometric outcomes and intermediate disease markers in patients with overweight and obesity: system…

2020

This systematic review aims to investigate the effects of intermittent energy restriction (IER) on anthropometric outcomes and intermediate disease markers. A systematic literature search was conducted in three electronic databases. Randomized controlled trials (RCTs) were included if the intervention lasted ≥12 weeks and IER was compared with either continuous energy restriction (CER) or a usual diet. Random-effects meta-analysis was performed for eight outcomes. Certainty of evidence was assessed using GRADE. Seventeen RCTs with 1328 participants were included. IER in comparison to a usual diet may reduce body weight (mean difference [MD]: −4.83 kg, 95%-CI: −5.46, −4.21; n = 6 RCTs), wais…

Impacto del tratamiento periodontal en el ratio rnakl/opg

2015

La reabsorción ósea es uno de los procesos con mayor transcendencia en la periodontitis. El descubrimiento del eje RANKL/RANL/0PG (receptor activador de la osteoclastogénesis) supuso un avance en la comprensión del remodelado óseos fisiológico y patológico. Los recientes estudios realizados tanto a nivel histológico como a nivel del fluido crevicular, han comprobado el aumento del ratio RANKL/OPG en los pacientes con periodontitis.Nuevos conocimientos en ésta línea aportarán información sobre la patogenia y por tanto podrían ser utilizados en el diagnóstico y tratamiento periodontal. Objetivo: Determinar el efecto del tratamiento periodontal básico (raspado y alisado radicular, junto con in…
