Myasthenia Gravis Registry in China
Source: ClinicalTrials.gov · Last updated 5 Feb 2024 · Not updated for over 12 months - ask the site whether it is still open
Brief summary (registry, in English)
Myasthenia gravis (MG) is an autoimmune disease caused by dysfunction at the neuromuscular junction, characterized by partial or generalized skeletal muscle weakness and fatigability. The estimated annual incidence rate of MG in China is 0.68/100,000, with a high rate of relapse and poor treatment compliance. This study is a prospective, observational, multi-center patient registry across China. To support standardized management and follow-up of MG patients in China, a Cloud-based MG Patient Management Platform (CN MG Base) was established in September 2023 with the support of the Chinese Rare Diseases Alliance. The platform aims to collect longitudinal clinical data including demographic information, age of onset, medical history, comorbidities, medication usage, treatment responses, and others. It is intended to collect newly registered MG cases each year and follow up with these patients at one-year intervals for ten years

- Patients themselves or their guardians can understand and sign the informed consent form.
- To meet the eligibility criteria, at least one of the following additional criteria must be met:
- a. Positive Tensilon test;
- b. Decrease in compound muscle action potential by more than 10% with low-frequency repetitive nerve stimulation or widening of the "jitter" (the variability in time of the second action potential relative to the first) on single-fiber electromyography, with or without blocking;
- c. Positive antibodies: Serum testing positive for AChR antibodies, MuSK antibodies, or LRP4 antibodies.
