Hypothesis: the hyponatremia of multiple myeloma (m.m.)is true and not pseudohyponatremia by using the stewart approach to acid - base interpretation, would like to show that the positive charged m- proteins produced in m.m.result in true hyponatremia.

Condition Intervention Phase
Hyponatremia of Multiple Myeloma Other: blood test Phase 4

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: a Study to Evaluate the Electrolyte Changes in Particular Sodium,in Multiple Myeloma and the Effect of the m- Proteins on the Strong Ion Difference
