Hepatotoxicity is not increased in alcoholics with positive urinary cocaine metabolites.
Cocaine hepatotoxicity in mice has been reported by numerous investigators. Such hepatotoxicity in other animal models has been more difficult to produce. We prospectively assessed 1212 alcoholics admitted for detoxification for historical, clinical and laboratory evidence of concomitant cocaine/crack use and evidence of liver disease. The 470 cocaine positive subjects had both longer durations and higher average daily costs of cocaine/crack use than the 742 cocaine negative subjects, but had a shorter duration of alcohol use. Serum transaminases were higher in the cocaine negative group. There were no clinically severe cases of liver disease or rhabdomyolysis in either group. Serum hepatitis B surface antibody and hepatitis A antibody were more frequent in the cocaine positive subjects. In conclusion, in this large sample of alcoholics abusing cocaine, severe hepatotoxicity was not at all evident. The previous reports of hepatotoxicity may represent co-morbidity. Some possibilities include infection with a hepatitis or other virus, the presence of an adulterant, an idiosyncratic reaction or an enzymatic abnormality.
