The study examines efgartigimod and intravenous immunoglobulin (IVIg) in elderly patients with generalized myasthenia gravis (GMG), focusing on changes in Myasthenia Gravis Activities of Daily Living (MG-ADL) scores, pyridostigmine dosage, and minimal symptom expression (MSE) over an 8-week period. Among 74 enrolled patients, efgartigimod showed greater reduction in MG-ADL scores compared to IVIg at weeks 4 and 8, with no serious adverse events, suggesting its superior efficacy and safety in elderly Chinese patients with acetylcholine receptor antibody-positive (AChR-Ab(+)) GMG.

Robotic gastrectomy is a safe and minimally invasive approach that may reduce the risk of complications in patients with severely impaired pulmonary function. Here, we report the successful treatment of an 80-year-old patient with gastric cancer and myasthenia gravis(MG)using perioperative respiratory rehabilitation and robotic gastrectomy with D2 lymphadenectomy. Patients with gastric cancer and severe pulmonary dysfunction are at a risk of postoperative respiratory disorders, including severe pneumonia.

BACKGROUND Cardiomyopathy associated with thymoma is thought to be a cardiac manifestations of myasthenia gravis (MG). However, there are case reports of newly diagnosed thymoma presenting with cardiomyopathy without MG, and the mechanism remains unclear. The purpose of this report is to explore tachycardia-induced cardiomyopathy (TIC) as a potential mechanism for cardiomyopathy in thymoma without features of MG.

Several new treatment concepts have emerged in recent years, but access to these treatments varies due to differing national reimbursement regulations, leading to disparities across Europe. This highlights the need for high-quality data collection by stakeholders to establish MG registries.

Background: The long-term treatment of myasthenia gravis (MG) and impaired productivity related to physical decline incur significant economic burdens on affected populations and society. This study aims to evaluate the costs of MG in China from a societal perspective and to identify the cost-driving factors.

Methods: A web-based survey was conducted on 1020 MG patients recruited through a national registry system in China.
