Summary

"This trial aims to study a new treatment for severe hypoparathyroidism that can occur after thyroid surgery. The treatment involves transplanting parathyroid tissue from a deceased donor to the patient,

Who is the study for?
This trial is for individuals with severe hypoparathyroidism that persists after thyroid surgery and doesn't respond well to standard treatments. Participants must be struggling with symptoms despite conventional therapy.
What is being tested?
The study is testing the safety and effectiveness of transplanting parathyroid tissue from a deceased donor into patients who have not responded to other treatments for severe post-surgical hypoparathyroidism.
What are the potential side effects?
Potential side effects may include complications related to surgery, reactions to the new parathyroid tissue, and issues arising from immunosuppressive drugs needed to prevent rejection.

Trial Design

1Treatment groups
Experimental Treatment
Group I: Parathyroid TransplantExperimental Treatment1 Intervention
Patients with permanent refractory hypoparathyroidism after total thyroidectomy will be entered in this study to undergo parathyroid transplantation from a neurologically deceased donor. Inclusion criteria are patients who have had a prior total thyroidectomy with both biochemical hypoparathyroidism and symptomatic hypocalcemia (numbness, tingling, or other neurologic symptoms) requiring daily high dose calcium (greater than 2000 mg per day), vitamin D (greater than 2 mcg of calcitriol per day) supplementation and/or intermittent IV calcium infusion. Patients for inclusion must have failed this medical management after at least 1 year of treatment and meet standard criteria for receiving organ transplant.
