Filter by:Background: The pathogenesis of NMOSD has been linked to the cytokines interleukins (IL) -6, NOD-, LRR-and pyrin domain-containing 3 (NLRP3) and IL-18 that contribute to development of inflammatory reactionsmay. Although azathioprine (AZA) is efficacious in preventing NMOSD recurrence, it may have adverse effects (AEs) maybe related to the plasma concentrations. Objective: We would monitor the blood concentrations of AZA in NMOSD, and their relationship with cytokines, severity, efficacy, and safety range of the drug. Methods: A total of 53 NMOSD patients were included in the study, which included 20 patients who had received AZA treatment within 1 month, and 16 patients who had received AZA treatment within 6 months, as well as 17 patients who had received AZA treatment at least 12 months. The patient's immunotherapy regimen was low-dose hormone combined with AZA. AZA was started at small doses and added every two weeks after no AEs, namely 50 mg qd for two weeks, 50mg bid for two weeks, and maintained at 50mg tid. The following clinical data were collected: gender, age, clinical symptoms, EDSS score, number of recurrences and AEs, etc. Healthy controls (HC) comprised 10 individuals. AZA metabolite concentrations 6-thioguaninenucleotides (6-TGN) and 6-methylmercaptopurine nucleotides (6-MMPN) were measured by High-performance liquid chromatography (HPLC). Levels of IL-6, NLRP3 and IL-18 were measured by Enzyme-linked immunosorbent assay (ELISA).
This is a Phase I study designed to assess the safety, tolerability and pharmacokinetics of LP-168 in healthy human volunteers.
The purpose of this study is to collect French medical data for patients with Multiple Sclerosis (MS) or NeuroMyelitis Optica (NMO) spectrum disorder who are diagnosed or strongly suspected of being infected with Covid19. The objective of this study is to provide scientific information regarding the possible risk factors in these patients, as a large part of them receive immunomodulatory or immunosuppressive treatments. The main objective of this study is thus to determine the epidemiological (eg, age, form of disease, disability) and pharmacological (related to immunomodulatory or immunosuppressive treatments) factors favoring the occurrence of a severe form of Covid-19 in MS and NMO patients.
Primary Objectives:To investigate the safety and tolerability of HBM 9161 in patients with attack of NMOSD in China
This study is being done to develop a database of pediatric patients in order to study the cause, early detection and best treatment for neuromyelitis optica spectrum disorder (NMOSD) in pediatric patients.
