  • Title: [Wilson's disease--critical deterioration under high-dose parenteral penicillamine therapy].
    Author: Hilz MJ, Druschky KF, Bauer J, Neundörfer B, Schuierer G.
    Journal: Dtsch Med Wochenschr; 1990 Jan 19; 115(3):93-7. PubMed ID: 2298126.
    Abstract:
    A 31-year-old man with Wilson's disease, not treated for the past 4 1/2 years, was admitted to hospital with brain concussion after a fall. While receiving penicillamine, 1 g i.v. four times daily, the neurological signs worsened and akinesia, mutism, tachy- and bradyarrhythmias, as well as transitory respiratory insufficiency developed. Serum copper concentration on the sixth day of treatment was markedly decreased to 28 micrograms/dl, rising to 60 micrograms/dl on the ninth day. 24-hour urinary copper excretion was at first 4500-5000 micrograms. Only after drastic reduction of the penicillamine dosage to 600 mg three times daily was there any improvement and after 11 weeks the patient was again able to walk and was discharged. Marked, mainly hepatic, copper depletion from the high penicillamine dosage was the likely cause of the patient's initial deterioration. To avoid cerebral complications penicillamine should be administered in gradually increasing doses.
