Chelation of gadolinium with deferoxamine in a patient with nephrogenic systemic fibrosis.

Abstract

A 65-year-old female with biopsy-confirmed nephrogenic systemic fibrosis (NSF) received a kidney transplantation. Despite good kidney function, her symptoms continued to progress. Deferoxamine was administered intramuscularly at 500 mg/day and later 1000 mg/day after 1 week with no adverse effects. Urine excretion of gadolinium increased from 6.0 μg/day to 11.6 μg/day and subsequently to 13.0 μg/day with 500 mg/day and 1000 mg/day of deferoxamine, respectively. Serum levels, however, remain unchanged from 1.7 ng/ml to 1.4 ng/ml. Although chelation therapy may have a role in the treatment of NSF, deferoxamine is too weak and a stronger chelator is needed.
