Abstract:
A 53-year-old African-American man with relapsed non-Hodgkin's lymphoma developed seizures and respiratory arrest 2 hours after an infusion of high-dose etoposide in preparation for an autologous bone marrow transplant. Laboratory tests revealed both rapid hemolysis and severe metabolic acidosis. The patient died the following day. Based on toxicities observed, we suspect that our patient possessed an ethnic polymorphism of the enzyme alcohol dehydrogenase. Further research is required to determine the relationship between the benzyl alcohol metabolic rate and toxicity and genetic polymorphisms of alcohol dehydrogenase in African-Americans.
