Effects of IV-Administered Ca-DTPA and Zn-DTPA To Treat Patients With Gadolinium Deposition Disease

"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."

"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.
