BACKGROUND Hypoparathyroidism remains the only hormone deficiency-related disorder with a standard treatment that is not based on replacing a missing hormone. Growing evidence supports the use of recombinant human parathyroid hormone (PTH), mostly with subcutaneous injections. More recently, some clinicians have administered teriparatide, a pharmaceutical form of PTH, through continuous delivery systems. CASE REPORT A 31-year-old woman was referred to our department for further evaluation of chronic severe hypocalcemia due to iatrogenic postsurgical hypoparathyroidism. Despite being chronically medicated with high doses of calcium, vitamin D, and subcutaneous teriparatide injections, she still reported symptoms of hypocalcemia on a daily basis and frequently needed treatment with intravenous calcium perfusions. During hospitalization, we ruled out treatment noncompliance and documented 6 episodes of severe hypocalcemia. Our team then decided to implement a continuous subcutaneous perfusion of teriparatide through an insulin pump. After optimizing the infusion rate, no more severe hypocalcemia episodes occurred. Four months after hospital discharge, it was possible to fully suspend oral supplementation therapy, and the patient's serum calcium level consistently remained within normal range. No other episodes of hypocalcemia occurred. CONCLUSIONS The only way to effectively restore long-term calcium homeostasis in our patient was to start a continuous subcutaneous infusion of teriparatide. There was no need to maintain calcium or vitamin D supplementation and we were able to halve the required daily dose of teriparatide. To our knowledge, this case represents one of the very few reports of successful treatment of hypoparathyroidism with a continuous perfusion of PTH.
