Summary

Purpose: There are two goals we have for this prospective single arm study; to see an increase in the amount of gadolinium in 24 hour urine collection following each infusion treatment with Calcium and Zinc DTPA, and to see a reduction or elimination of gadolinium deposition disease (GDD) symptoms.

Participants: Twenty (20) patients who are suffering from gadolinium deposition disease (GDD)

Procedures: Over a series of three (3) treatment time-points patients will be treated with IV Ca-DTPA on day one, and Zn-DTPA on day two.

Conditions

Interventions

DRUG

Calcium DTPA

On Day 1, 2.5 mL of Ca-DTPA (1 g/5 mL) will be administered over a period of 1 minute. A solution of normal saline will then be administered at a rate of 300 mL/hr over 30 minutes. Patients will be seated with hands lowered to their sides to allow the chelator to dwell slightly in the soft tissues of the hands and feet. Patients will then be moved to a supine position and the infusion rate increased to 750 mL/hr over the next 60 minutes. At 90 minutes the remaining 2.5 mL of Ca-DTPA will administered IV over a period of 1 minute, and the normal saline will continue for the remaining 9 minutes. The IV line will then be removed. Patients will be instructed to drink plenty of fluids that evening. The same treatment therapy will consist of 3 time-points, approximately 1 month apart.

DRUG

Zinc DTPA

On Day 2, 2.5 mL of Zn-DTPA (1 g/5 mL) will be administered over a period of 1 minute. A solution of normal saline will then be administered at a rate of 300 mL/hr over 30 minutes. Patients will be seated with hands lowered to their sides to allow the chelator to dwell slightly in the soft tissues of the hands and feet. Patients will then be moved to a supine position and the infusion rate increased to 750 mL/hr over the next 60 minutes. At 90 minutes the remaining 2.5 mL of Zn-DTPA will administered IV over a period of 1 minute, and the normal saline will continue for the remaining 9 minutes. The IV line will then be removed. Patients will be instructed to drink plenty of fluids that evening. The same treatment therapy will consist of 3 time-points, approximately 1 month apart.
