Abstract:

Zinc has been developed as an effective and nontoxic therapy in Wilson’s disease. Zinc salts are generally well tolerated. Mild gastrointestinal discomfort is the major observed side effect and may be dependent on the zinc salt employed. Here, we report two Wilson’s disease patients who presented with severe gastric ulceration few months after beginning treatment with zinc acetate 50 mg three times a day. Our patients were not taking any ulcerogenic drugs and had no evidence of Helicobacter pylori infection. In both patients, zinc acetate was replaced by penicillamine and proton pump inhibitor therapy was initiated with complete resolution of gastrointestinal symptoms. To our knowledge, this is the first report of zinc acetate-induced gastric ulceration, which should be looked for in Wilson’s disease patients who develop abdominal discomfort while on this drug.
