My Mom was diagnosed with MG last year and keeps on having flares and hospital admissions. She just got out of hospital two weeks ago and is now back in. My mom tested positive for MuSK antibodies which I heard is hard to maintain.

MuSK antibody-positive MG requires a different treatment approach since traditional anticholinesterase medications like pyridostigmine (Mestinon) are often less effective. In fact, only about 16% of MuSK-positive patients respond well to these medications, and some may experience worsening symptoms.

For MuSK-positive Show Full Answer

MuSK antibody-positive MG requires a different treatment approach since traditional anticholinesterase medications like pyridostigmine (Mestinon) are often less effective. In fact, only about 16% of MuSK-positive patients respond well to these medications, and some may experience worsening symptoms.

For MuSK-positive patients, doctors typically recommend immunosuppressant treatments as the primary approach. Treatment options that may help manage your mom's condition include:

• Immunosuppressive medications like prednisone
• Plasma exchange (plasmapheresis)
• Intravenous immunoglobulin (IVIg) therapy
• Complement inhibitors like eculizumab
• Newer targeted therapies like rozanolixizumab-noli

Since your mom is experiencing frequent flares, her neurologist may need to adjust her treatment plan. Each person's response to treatment is different, so it may take time to find the most effective combination of therapies.
