Successful treatment by plasmapheresis of respiratory insufficiency in myasthenia gravis.
A 27-year-old man with myasthenia gravis developed a severe myasthenic crisis with respiratory insufficiency. In spite of high iv doses of pyridostigminebromide and corticosteroids, mechanical ventilation remained necessary. Treatment with plasma exchange grossly decreased the serum level of antibodies against acetylcholine receptor protein and caused an immediate clinical improvement. The respiratory assistance could be terminated and muscle strength increased substantially. Plasmapheresis seemed to be of definite benefit in the treatment of this acute crisis of myasthenia gravis.
