Wernicke encephalopathy complicating lymphoma therapy: case report and literature review.

摘要

Thiamine deficiency can occur in any disease that results in inadequate intake or excessive loss of vitamin B1. In addition to increased thiamine consumption secondary to high cell turnover, cancer patients frequently have reduced oral intake as a direct result of their cancer or from cancer treatments. However, Wernicke encephalopathy (cerebral Beriberi), a clinical manifestation of thiamine deficiency, has rarely been associated with cancer patients. We report a case of Wernicke encephalopathy in a nonalcoholic patient with lymphoma. Although thiamine deficiency rarely potentiates clinical sequelae in cancer patients, it is important to recognize the risk and the clinical signs and manifestations so that prompt therapy can be initiated to reverse morbidity.
