Long-Term Treatment With Ocrelizumab in Patients With Early-Stage Relapsing MS: Nine-Year Data From the OPERA Studies Open-Label Extension.
Neurology
February 2025
Department of Neurology and Center of Clinical Neuroscience, First Medical Faculty, General University Hospital and Charles University, Prague, Czech Republic.
Background And Objectives: Patients with multiple sclerosis (MS) may demonstrate better disease control when treatment is initiated on high-efficacy disease-modifying therapies (DMTs) from onset. This subgroup analysis assessed the long-term efficacy and safety profile of the high-efficacy DMT ocrelizumab (OCR) as first-line therapy for early-stage relapsing MS (RMS).
Methods: Post hoc exploratory analyses of efficacy and safety were performed in a subgroup of treatment-naive patients with RMS who received ≥1 dose of OCR in the multicenter OPERA I/II (NCT01247324/NCT01412333) studies.
SIV monoclonal antibody administration spanning treatment interruption in macaques delays viral rebound and selects escape variants.

HIV-1 envelope broadly neutralizing antibodies represent a promising component of HIV-1 cure strategies. To evaluate the therapeutic efficacy of combination monoclonal antibodies (mAbs) in a rigorous nonhuman primate model, we tested different combinations of simian immunodeficiency virus (SIV) neutralizing mAbs in SIVmac251-infected rhesus macaques. Antiretroviral therapy-suppressed animals received anti-SIV mAbs targeting multiple Env epitopes spanning analytical treatment interruption (ATI) in 3 groups (n = 7 each): i) no mAb; ii) 4-mAb combination; and iii) 2-mAb combination.

J Clin Endocrinol Metab
January 2025
Gastroenterology, Hepatology and Nutrition, Cincinnati Childrens Hospital Medical Center, Department of Pediatrics, University of Cincinnati College of Medicine, Cincinnati, OH.
Context: Our study explores the impact of human PTH 1-34 injections (PTH therapy) on growth, areal bone mineral density (BMD), and bone quality (measured by trabecular bone score, TBS) in hypoparathyroidism due to autoimmune polyendocrine syndrome type 1 (APS-1) or an activating variant of the calcium sensing receptor (CaR).
Objective: To assess associations of 1) age and PTH therapy duration with age-standardized Z-scores for height (HAZ), BMD (BMD-Z), and TBS (TBS-Z) in CaR or APS-1, and 2) APS-1 disease severity with BMD-Z and TBS-Z.
Methods: This secondary analysis pooled linear growth and lumbar spine (LS) DXA data from studies of hypoparathyroidism with mean baseline age of 13.
An Update on Multi-System Inflammatory Syndrome in Children.
Curr Rheumatol Rep
January 2025
Division of Rheumatology, Department of Pediatrics, The Warren Alpert Medical School of Brown University, 593 Eddy Street, Providence, RI, 02903, USA.
Purpose: To summarize the latest research on the epidemiology, pathogenesis, diagnosis, and treatment of multisystem inflammatory syndrome in children (MIS-C).
Recent Findings: The epidemiology of MIS-C has been dynamic since its initial description. The pathogenesis remains poorly understood.
Investigating the role of IL-6 in the pathogenesis of systemic lupus erythematosus: Insights from bone marrow mesenchymal stem cells.
Lupus
January 2025
Department of Dermatology, Nanfang Hospital, Southern Medical University, Guangzhou, People's Republic of China.
Background: Systemic lupus erythematosus is a common autoimmune disease. Studies have suggested that defective stem cells could be involved in the pathogenesis of systemic lupus erythematosus, which leads to changes in the function of immune cells. By observing the cell morphology, autophagy, and senescence of bone marrow mesenchymal stem cells (BMSCs) from lupus mice and normal controls, this study investigated the role of IL-6 in autophagy and senescence of BMSCs and explored relevant mechanisms.
