The effect of continuous subcutaneous recombinant PTH (1-34) infusion during pregnancy on calcium homeostasis - a case report.

OBJECTIVE

We describe calcium homeostasis during pregestation and gestation in a woman with iatrogenic hypoparathyroidism, treated with continuous subcutaneous recombinant parathyroid hormone (PTH) (1-34) infusion.

RESULTS

The requirement for PTH did not fluctuate much during pregnancy and was essential for maintaining normal calcium and phosphorus serum levels.

CONCLUSIONS

This study documents the insufficiency of PTH-related protein (PTHrP) or other gestation-related hormones to compensate for PTH deficiency in hypoparathyroid women, and the successful utilization of continuous subcutaneous recombinant PTH (1-34) infusion to achieve normal calcium homeostasis during gestation. Clinical trials with PTH replacement in such circumstances are warranted.
