Evaluation of the Condition of Patients Receiving EARLY Ravulizumab and Admitted in ICU for gMG Crisis

Myasthenia Gravis (MG) is a rare autoimmune disease that causes muscle weakness and fatigue. It occurs when the immune system produces antibodies that block communication between nerves and muscles. In some patients, the disease can suddenly worsen and cause severe breathing problems. This life-threatening situation is called a myasthenic crisis and requires immediate treatment in an intensive care unit (ICU). During such crises, patients may need to receive respiratory assistance through a ventilator. These episodes are often long and can lead to complications such as infections or heart problems. To manage a myasthenic crisis, doctors usually use treatments that remove or neutralize the harmful antibodies: plasma exchange (PLEX) or intravenous immunoglobulin (IVIg). Although both are effective, recovery can be slow, and many patients remain in the ICU for several weeks. Ravulizumab (Ultomiris®) is a new medicine that targets a specific part of the immune system called the complement system, which contributes to muscle damage in MG. It is already approved for adults with generalized MG who have anti-acetylcholine receptor (AChR) antibodies. Ravulizumab is given by intravenous infusion every eight weeks. Clinical studies have shown that it can improve symptoms within one week of starting treatment. Some doctors have started using ravulizumab early, after PLEX or IVIg, for patients hospitalized in the ICU for a myasthenic crisis. Early use of this treatment could help reduc…
