Objectives: To assess immunogenicity and safety in patients with active rheumatoid arthritis (RA) transitioning from rituximab [US-licensed rituximab: Reference Product (RP); EU-approved rituximab: Reference Medicinal Product (RMP)] to DRL_RI (proposed rituximab biosimilar), in comparison to those continuing on RP/RMP.

Methods: This double-blind, randomized, Phase 3 study included 140 RA patients having prior exposure to RP/RMP; transitioned to DRL_RI (n = 70) or continued with RP/RMP (n = 70) for two 1000 mg infusions on Days 1 and 15. Assessments included Time-matched Rituximab Concentration (TMRC), anti-drug antibodies (ADAs), neutralizing antibodies (NAbs) and ADA titre over 12 weeks, and safety follow-up till 26 weeks.

Background: This study aimed to address research gap concerning the perception of the care pathway for knee osteoarthritis (KOA) patients, focusing on both the patient and health professional perspectives in countries with inefficient health systems, such as Slovenia, by examining patient satisfaction with conservative treatment, assessing the perceptions of both patients and health professionals regarding the latter's involvement, and justifying the chosen KOA treatment approaches.

Methods: A mixed-methods approach was employed, combining quantitative surveys and qualitative interviews with KOA patients (n = 82) and healthcare professionals (n = 68).

Results: The care pathway for conservative KOA treatment in Slovenia begins with general practitioners (GPs), who conduct initial examinations, prescribe analgesics, and refer patients to radiologists and orthopaedic surgeons.

Background: Hemophilic arthropathy (HA) is a joint disease characterized by local iron overload, stemming from erythrocyte rupture and closely linked to synovial lesions. However, the precise molecular characteristics of clinical HA synovial samples remain to be defined.

Objectives: To gain insight into HA synovial tissue lesions, we utilized a metalloprotein strategy to compare the metal and protein spectra of HA with those of osteoarthritis (OA) and rheumatoid arthritis (RA).

Rheumatoid arthritis (RA) is an autoimmune condition that predominantly affects synovial joints, manifesting with joint swelling, pain, and stiffness. In advanced stages, unchecked inflammation can inflict damage on bone and cartilage, resulting in disabilities and deformities of the joints. Additionally, systemic and extra-articular complications may arise due to the consequences of uncontrolled inflammation.

Background: Initiating urate-lowering therapy can trigger gout flares. Gout flares have been associated with a temporally increased risk of cardiovascular events. Therefore, we aimed to estimate the risk of cardiovascular events in patients with gout initiating urate-lowering therapy with flare prophylaxis using colchicine (the drug recommended for gout flare prohphylaxis by many international societies) compared with no prophylaxis.

Background: Diarrhoeal diseases claim more than 1 million lives annually and are a leading cause of death in children younger than 5 years. Comprehensive global estimates of the diarrhoeal disease burden for specific age groups of children younger than 5 years are scarce, and the burden in children older than 5 years and in adults is also understudied. We used results from the Global Burden of Diseases, Injuries, and Risk Factors Study 2021 to assess the burden of, and trends in, diarrhoeal diseases overall and attributable to 13 pathogens, as well as the contributions of associated risk factors, in children and adults in 204 countries and territories from 1990 to 2021.

Inflammation switches the chemoattractant requirements for naive lymphocyte entry into lymph nodes.

Cell

December 2024

Howard Hughes Medical Institute and Department of Microbiology and Immunology, University of California, San Francisco, San Francisco, CA 94143, USA. Electronic address:

Sustained lymphocyte migration from blood into lymph nodes (LNs) is important for immune responses. The CC-chemokine receptor-7 (CCR7) ligand CCL21 is required for LN entry but is downregulated during inflammation, and it has been unclear how recruitment is maintained. Here, we show that the oxysterol biosynthetic enzyme cholesterol-25-hydroxylase (Ch25h) is upregulated in LN high endothelial venules during viral infection.

Risk factors associated with subtalar fusion within 5 years following calcaneal ORIF.

Foot (Edinb)

December 2024

Maimonides Medical Center, Department of Orthopedic Surgery, 4802 Tenth Avenue, Brooklyn, NY 11219, United States.

Background: Although most calcaneal fractures are managed with open reduction internal fixation (ORIF), they can ultimately lead to subtalar arthritis and pain requiring subtalar fusion when conservative treatments prove ineffective. Understanding the risk factors associated with subtalar fusion (STF) after calcaneal ORIF is crucial for optimizing patient outcomes and treatment strategies. This study aimed to comprehensively evaluate these risk factors and their association with the incidence of STF, including patient demographics, medical comorbidities, same day and 90-day reimbursement data.

Introduction: Perioperative steroids administration in total joint arthroplasty gained popularity for pain relief, reduction of postoperative nausea and vomiting (PONV) and enhanced recovery. The purpose of this study is to systematically review and meta-analyze comparative results of prospective randomized trials focused on the effect of systemic steroid administration at different dosages in THA for hip osteoarthritis. The hypothesis is that perioperative systemic steroid administration has a positive impact on postoperative outcomes.

Background: Accumulating evidence suggests that the radiographic phenotypes of patients with knee osteoarthritis (KOA) often do not correlate with their clinical findings, which are the primary reason for seeking medical care. Therefore, at OARSI 2024, we proposed a clinical finding staging system-Chinese medicine staging (CMS)-to guide the treatment of KOA. However, the clinical effectiveness and application characteristics of CMS in guiding non-surgical treatment of KOA remain unclear.

Osteoarthritis (OA) is the most common disease in aging joints and has characteristics of cartilage destruction and inflammation. It is currently considered a metabolic disease, and the CH25H-CYP7B1-RORα axis of cholesterol metabolism in chondrocytes plays a crucial catabolic regulatory role in its pathogenesis. Targeting of this axis in chondrocytes may provide a therapeutic approach for OA treatment.

Background: To investigate the associations of methylation, expression, and protein quantitative trait loci (mQTL, eQTL, and pQTL) with ankylosing spondylitis (AS) and find out genetically supported drug targets for AS.

Methods: The summary-data-based Mendelian randomization (SMR) and Bayesian co-localization analysis were used to assess the potential causality between AS and relevant genes. The GWAS data obtained from the International Genetics of Ankylosing Spondylitis Consortium (IGAS) were set as the discovery stage, and the FinnGen and UK Biobank databases were used to replicate the analysis as an external validation.

Background: The Intensive Diet and Exercise for Arthritis (IDEA) trial was a randomized trial conducted to evaluate the effects of diet and exercise on osteoarthritis (OA), the most prevalent form of arthritis. Various risk factors, including obesity and sex, contribute to OA's debilitating nature. While diet and exercise are known to improve OA symptoms, cellular and molecular mechanisms underlying these interventions, as well as effects of participant sex, remain elusive.
