The occurrence of electrolyte disorders as hypocalcemia and/or hyponatremia is an uncommon event in preeclampsia, which can be the sign of serious situation, with potentially unfavourable consequences for the mother and her fœtus. Hyponatremia in the setting of preeclampsia is an indicator of severity, and requires the understanding of the etiologic mechanisms to initiate an appropriate treatment. Indeed the often-considered fluid restriction is rarely a treatment option for pregnant women. Hypocalcemia is a complication that must be monitored when a treatment with high doses of intravenous magnesium sulphate is introduced. In this context, hypocalcemia must be sought, with the exclusion of other etiologies as vitamin D deficiency, hypoparathyroidism or renal and extrarenal loss of calcium. A replacement therapy, intravenous or oral according to circumstances, should be considered in case of severe or symptomatic hypocalcemia.

Humori-positive neurosecretory cells of the supraoptic nucleus of the hypothalamus have been investigated during various time of parathyroprival hypocalcemia after extirpation of the parathyroid glands. Contents of total and ionized calcium, phosphorus in blood serum have been estimated. Volume of nuclei and nucleoli has been measured. In 5 days functional activity of the supraoptic nucleus increases (lightly stained cells predominate, volume of the nuclei and nucleoli increases). In subsequent 15-30 days its activity decreases (increase in amount of dark-stained cells, nucleolar volume decreases). In 60 days there is a tendency to restoration of neurosecretion.
