Lymphoplasma Exchange Can Ease MG Symptoms in Flares, Study Finds

Lymphoplasma exchange — a procedure that involves exchanging a patient’s plasma and also removing certain immune cells from the bloodstream — can ease symptoms of acute exacerbations of myasthenia gravis (MG), a new study reports. The study, “Lymphoplasma Exchange Improves Myasthenia Gravis Exacerbations: A Retrospective Study…

Ultomiris Is Approved in the US for Treating AChR-positive gMG

The long-acting complement inhibitor Ultomiris (ravulizumab-cwvz) has been approved by the U.S. Food and Drug Administration (FDA) to treat most adults with generalized myasthenia gravis (gMG). The approval specifically covers patients who are positive for antibodies against the acetylcholine receptor (AChR) — about 80% of gMG patients. “With the…

Europe Awaits Proposed New Framework for Sharing Health Data

The European Commission is expected to propose a new governing framework for health data next month, called the European Health Data Space (EHDS), with the aim of connecting national health systems to facilitate secure and efficient transfer of data across systems in different European nations. The move is expected to…

Study Details Clinical Course of Anti-MuSK-positive MG

Many people with myasthenia gravis (MG) caused by antibodies against MuSK initially present with eye-related symptoms, which soon affect other parts of the body, according to a new study. “The present study provides a better understanding of MuSK-MG disease and its clinical course,” its researchers wrote. The study, “…

Soliris Outperforms Rituximab at Controlling MG Symptoms: Study

Soliris (eculizumab) is better than rituximab at controlling myasthenia gravis (MG) symptoms over a two-year period, according to a new analysis. Results were detailed in the study, “Eculizumab versus rituximab in generalised myasthenia gravis,” published in the Journal of Neurology, Neurosurgery and Psychiatry. Soliris…

Model of Neuromuscular Junction May Help Evaluate MG Treatments

Scientists described a new cellular model of the neuromuscular junction that could be useful for diagnosing myasthenia gravis (MG) or developing new treatments for the condition. “New approaches for the treatment of neurodegenerative diseases are sorely needed, as decades of research have resulted in limited therapeutic advances. We hope…
