BACKGROUND: Experience with zinc in treating symptomatic hepatic Wilson's disease (WD) is limited.
AIM: To study the efficacy of Penicillamine followed by zinc in treating symptomatic hepatic Wilson's disease.
METHODS: We retrospectively analyzed case records of 31 symptomatic hepatic WD patients for whom disease severity scores (Child's, model for end-stage liver disease (MELD), Nazer's, and New Wilson Index (NWI) score) and 24-h urinary copper were compared at 3-time points-baseline at presentation, at transition from penicillamine to zinc and at end of follow up.
RESULTS: Thirty-one patients (median age 11 [5-24] years) with symptomatic hepatic WD were studied; ten had associated neuropsychiatric manifestations of WD. Penicillamine was changed to zinc sulfate either due to financial constraints (28 patients) or due to adverse effects of penicillamine (3 patients). At presentation (baseline), six patients belonged to Child's class A, five to Child's B, and 17 to Child's C. Duration of initial penicillamine chelation therapy was 134 (2-320) weeks, and of subsequent zinc therapy was 363 (35-728) weeks. There was a significant improvement in liver function tests and disease severity scores (Child's, MELD, Nazer's, and NWI score) at the transition from penicillamine to zinc compared to baseline. This improvement was maintained until the end of study period with 90% survival at 10 (2-20) years. Fifteen of the 17 Child's C cirrhotic patients showed significant improvement in disease severity scores from baseline until end of follow up.
CONCLUSIONS: Penicillamine followed by zinc may be a safe and effective treatment in resource-constrained setting for symptomatic hepatic WD patients in all grades of baseline disease severity. Some patients with decompensated cirrhosis due to WD may be managed with medical treatment, avoiding liver transplantation.
