INTRODUCTION: Giant cell arteritis (GCA) is complicated in 10 to 20% of cases by permanent visual ischemia (PVI). International guidelines advocate the use of intravenous pulse of methylprednisolone from 250 to 1000 mg per day, for three days, followed by oral prednisone at 1 mg/kg per day. The aim of this study is to assess whether this strategy significantly reduces the risk of early PVI of the second eye, compared with direct prednisone at 1 mg/kg per day. METHODS: We conducted a multicentre retrospective observational study over the past 15 years in 13 French hospital centres...

Obesity is one of the main modifiable risk factors for osteoarthritis (OA). Moreover, obesity is associated with greater pain intensity and functional limitation but also with a significantly lower responder rate to intra-articular treatments. Consequently, an arthroplasty is indicated earlier and more frequently in patients with obesity. However, pain and functional symptoms improves slightly less after arthroplasty in patients with obesity, who display higher incidence of early and late complications following prosthetic surgery...

INTRODUCTION: Poor prognostic factors (PPFs) have been used in assisting therapeutic decision-making in rheumatoid arthritis (RA). There are no standard lists of PPFs for RA, and whether PPFs can guide RA treatment remains controversial. OBJECTIVES: To analyze the profile of PPF based on EULAR recommendations in RA patients and explore the necessity of considering these PPFs in adjusting therapy. METHODS: Prognostic factors including erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), rheumatoid factor (RF), anti-citrullinated protein antibody (ACPA), swollen joint count (SJC), early erosions, and response to first conventional synthetic disease-modifying anti-rheumatic drugs (csDMARD) therapy in 1164 RA patients were collected...

Osteoarthritis (OA), the leading cause of disability in the elderly, still lacks effective treatment due to the unelucidated mechanisms of pathogenesis and progression. In cartilage, although the solo cell type of chondrocytes is resident, cartilage progenitor cells (CPCs) are identified. Chondrocytes in cartilage mainly utilize glycolysis because of the low oxygen tension. Until now, whether the metabolic pathway changes are associated with OA initiation or progression, as well as the biology of CPCs, remains fully clarified...

The improved understanding of the molecular basis of innate immunity have led to the identification of type I interferons (IFNs), particularly IFN-α, as central mediators in the pathogenesis of several Immune-mediated inflammatory diseases (IMIDs) such as systemic lupus erythematosus (SLE), systemic sclerosis, inflammatory myositis and Sjögren's syndrome. Here, we review the main data regarding the opportunity to target type I IFNs for the treatment of IMIDS.Type I IFNs and their downstream pathways can be targeted pharmacologically in several manners...

OBJECTIVE: The main objective of the study was to see the concordance between the diagnosis of gout recorded in primary care electronic medical records and the ACR/EULAR 2015 classification criteria. METHODS: A cross-sectional study was conducted using electronic medicals records in 7 primary care centres of Barcelona. Patients data to study clinical diagnose and management was gathered from the primary care electronic medical records of the Catalonian health institute (Institut Català de la Salut, ICS) and phone interview...

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by immune dysregulation and organ injury with a premature mortality due to cardiovascular diseases. Platelets, that are primarily known for their role in hemostasis, have been shown to play an active role in the pathogenesis and in the progression of immune-mediated inflammatory diseases. Here we summarize the evidence of their roles in SLE pathogenesis which supports the development of targeted treatments. Platelets and their precursors, the megakaryocytes, are intrinsically different in SLE patients compared with healthy controls...

INTRODUCTION: Chronic pain is a common symptom of rheumatic diseases that impacts patients' quality of life. While non-pharmacological approaches are often recommended as first-line treatments, pharmacological interventions are important for pain management. However, the effectiveness and safety of different pharmacological treatments for chronic pain in rheumatic diseases are unclear. METHODS: This review critically synthesizes the current evidence base to guide clinicians in selecting appropriate pharmacological treatments for their patients, considering the expected benefits and potential risks and side effects...

Axial psoriatic arthritis (axPsA) has considerable overlap with axial spondyloarthritis (axSpA) but has some unique features that sometimes preclude classification into axSpA. It has some clinical and radiographic differences compared to axSpA. Imaging typically shows asymmetric syndesmophytes, mainly in the cervical spine, with less frequent sacroiliitis. It more commonly presents later in life and is associated with less severe inflammatory back pain than axSpA. The interleukin (IL) IL-23/IL-17 axis is central to the pathogenesis of both diseases...

Long COVID syndrome is characterized by new, returning, or persistent symptoms after the initial SARS-CoV-2 infection. Among the potential long-term effects of COVID-19, several different musculoskeletal symptoms have been reported in many patients with an important impact on quality of life. The rehabilitation needs of Long COVID patients could be dynamic. However, to date there are no studies that have evaluated how the rehabilitation needs of patients with Long COVID syndrome have changed over time. We conducted a literature review to summarize the most recurrent manifestations of the Long COVID syndrome during the three years of the pandemic, as well as the evolution of musculoskeletal symptoms, through lexical analysis...

Axial spondyloarthritis (axSpA) is the prototype of the spondyloarthritis spectrum. The involvement of T cells in its pathogenesis has long been suspected on the basis of the association with the major histocompatibility complex I molecule HLA-B27 and the pivotal role of interleukin 17 in the inflammatory mechanisms associated with the disease. Moreover, the presence of unconventional or "innate-like‿ T cells within the axial enthesis suggests an important role for these cells in the pathophysiology of the disease...
