Filter by:This study is designed to evaluate the effectiveness and safety of low-dose rituximab in patients with refractory myasthenia gravis. The traditional treatment of MG is immunosuppressive therapy, usually beginning with corticosteroids. However, up to 70% of treated patients show an incomplete response, including 10 - 30% who are unresponsive. Corticosteroids and other immunosuppressive therapies presented also many side effects. The investigators propose to evaluate in a pilot, open, prospective, single central study, the interest of rituximab (RTX) in the treatment of patients with refractory MG. Fifty patients with refractory MG will be included in the study and divided into two stages: 14 patients in the first stage were followed up after using RTX according to the study protocol. The study will move into the second stage on if the number of effective cases is greater than 3, otherwise, the study will be discontinued (based on Simon's Optimal Two-stage Design). The remaining 36 patients were enrolled in the second stage. In the first and second stages, the treatment plan and follow-up plan were consistent. The therapeutical schema is rituximab 100-200 mg/week for a total of 2-4 times, followed by adequate organ function, laboratory parameters and assessment of MG after each injection and end of follow up for 24 weeks.
The primary study objective is to evaluate medium- and long-term safety of HBM9161 in combination with background treatment for gMG patients through the observation on adverse events and laboratory abnormalities during study period.
participants will be allocated into three groups, acute neuropathy (Guillain Barre Syndrome) group, neuromuscular junction disorder(myasthenia gravis ) group, and control group(people with neurological disorders not affecting the respiratory system.Ultrasonography is done on the diaphragm. The index test (ultrasound imaging of the diaphragm) is used. A high-resolution portable ultrasound machine is used, with a 7- to 13-MHz linear array transducer. Patients will be examined in the supine position. diaphragmatic thickness will is measured on both sides during a deep breath in inspiration and during expiration. objectives: primary outcome: to compare diaphragm thickness between the three examined groups. Secondary outcome: correlation between clinical scores and reference US values of diaphragm
Myasthenia gravis is a B-cell-mediated autoimmune disorders causing muscle weakness due to defective synaptic transmission at the neuromuscular junction caused by autoantibodies to acetylcholine receptors in (∼85%), muscle specific kinase in 6% and low-density lipoprotein receptor-related protein 4.The detection of these autoantibodies is very important not only in the diagnosis, but also for the stratification of Myasthenia Gravis patients into respective subgroups. These groups can differ in clinical manifestations, prognosis and response to therapies which become relevant for the development of antigen-specific therapies, targeting only the specific autoantibodies involved in the autoimmune response.
The purpose of this study is to determine the effect of nipocalimab on total serum immunoglobulin G (IgG) in pediatric participants 2 to less than (<) 18 years of age (globally) and 8 to <18 years of age (for Unites Stated (US) sites only), the safety and tolerability of treatment with nipocalimab in children and adolescents and to evaluate the pharmacokinetics (PK) of nipocalimab in children and adolescents with generalized myasthenia gravis (gMG) who have an insufficient clinical response to ongoing, stable standard-of-care therapy.
Recently, robotic-assisted thoracic surgery (RATS) has become into as an alternative approach to either, open surgery or video-assisted thoracoscopic surgery. The superiorities of RATS have been reported in series studies, such as intuitive movements, tremor filtration, more degrees of manipulative freedom, motion scaling, and high-definition stereoscopic vision. However, the currently reported robotic thymectomy used 3 ports. Theoretically, less incisions may bring faster postoperative recovery, lighter postoperative pain and higher postoperative quality of life. The investigators have successfully performed robotic thymectomy through 2 ports and even 1 port. However, the potential benefit of less ports robotic thymectomy has not been verified through well-designed cohort study, so this clinical trial has been designed.
The purpose of the study is to determine the effect acupuncture treatment on individuals with a diagnosis of Myasthenia Gravis (MG). A total of 20 people with MG will be enrolled in this study to receive acupuncture treatment 2 times a week for 12 weeks. Participants will be randomized into two groups: 1) Immediate start and 2) Delayed start (12 weeks). The delayed start group will act as a control group for the first 12 weeks, but then receive acupuncture treatment for 12 weeks. It is hypothesized that patients with MG who receive acupuncture treatment will have improved quality of life and activities of daily living compared to no treatment.
Myasthenia gravis (MG) is a neuromuscular junction (NMJ) disorder mediated by autoantibodies against AChR, MuSK or other autoantigens located at the post synaptic membrane of the neuromuscular junction. Presence of autoantibodies specific for AChR or MuSK can establish diagnosis in conjunction with clinical presentations. In most established guidelines for the diagnosis and treatment of myasthenia gravis, determination of AChR and MuSK antibodies has been recommended. Radioimmunoprecipitation assay (RIPA), enzyme-linked immunosorbent assay (ELISA), and cell-based assay (CBA) are all commercially available and have been adopted for autoantibody detection by most referring neurologists. At present, specificity and sensitivity of these methods have not been compared in large cohorts within a context of stringent quality control. As a consequence, there are no national or international consensus regarding selection of methods and interpretation of results, resulting in challenges to neurologists managing these patients. To this end, the investigators proposed to conduct a multicenter, double-blind, prospective study to compare the sensitivity and specificity of CBA, RIPA and ELISA assays to detect AChR and MuSK antibodies.
This study will evaluate the efficacy and safety of ALXN2050 (120 milligrams [mg], 180 mg) in participants with generalized myasthenia gravis (gMG). Safety will be monitored throughout the study.
This study aims to characterize the clinical features, frequency of different subgroups of MG, and identify predictors of treatment responsiveness among different subgroups of MG. The predictors are including primary outcome (percentage of changes in MG scales at baseline at time of enrollment and after 3 months) and secondary outcome (treatment-related adverse events). Also it aims to determine the frequency of patients with refractory MG. This information will be used to understand the trends and mechanisms of disease relapse, and optimal management strategies.
