Value of exchangeable electrolyte measurement in the treatment of myasthenia gravis.
Abstract
We have investigated electrolyte exchange in myasthenia gravis before and after corticotrophin therapy, using a four-isotope dilution technique. Clinical deterioration in patients on corticotrophin is associated with a fall of more than 20% in the intracellular potassium concentration, suggesting that all myasthenics so treated should be given potassium supplementation.
