title: Extreme hyponatremia in patients with myelomatosis: an effect of cationic paraproteins.
abstract: Three patients with IgG myelomatosis and extreme hyponatremia are described. By isoelectric focusing of the M-component it is demonstrated that the subnormal sodium value is most likely explained by a cationic effect of the myeloma globulin.
