Response to different therapeutic approaches in Wilson disease. A long-term follow up study
Journal Title: Annals of Hepatology - Year 2012, Vol 11, Issue 6
Abstract
Background and aims. There are certain areas of uncertainty regarding the best therapeutic approach in patients diagnosed with Wilson Disease (WD). Our aim was to assess treatment response to different therapies in a cohort of WD patients followed in a single center. Material and methods. This is an observational, descriptive study in which clinical, laboratory and imaging data are reviewed in a series of 20 WD patients with a median follow-up of 14 years. Type of presentation, treatment used, biochemical and copper homeostasis parameters were elicited. Results. Median age at diagnosis was 22 years. The most frequent form of presentation was hepatic (n = 10, 50%; mean age: 21.5 years), followed by neurological (25%; mean age: 34.5 years) and mixed (15%). The initial treatment in both symptomatic and asymptomatic patients at diagnosis was d-penicillamine in 90% and Zinc (Zn) in 10%, respectively. Patients who were maintained on d-penicillamine for the whole period had complete biochemical normalization (baseline ALT: 220 IU/l; last follow up 38 IU/l). In contrast, patients in whom d-penicillamine was switched to Zn, irrespective of the cause, did not show a complete biochemical remission (baseline ALT: 100 IU/l vs. 66 IU/l at last follow-up). Conclusions. Treatment was found to be effective in most cases regardless of the drug used. However, side effects were common in those treated with d-penicillamine agents, and required switching to zinc. Therapy with zinc was well tolerated and appeared to have a good efficacy. However, in 33%, a complete normalization of liver enzymes was never reached.
