Genetic and Environmental Susceptibility to Alcoholic Hepatitis

Constitutional, environmental, and genetic risk factors influence the development of alcohol-related cirrhosis. The amount of alcohol consumed and whether excessive drinking continues after the identification of pre-cirrhotic liver damage are key risk factors. Female sex, ethnicity, obesity, coffee consumption, cigarette smoking, and exposure to other causes of liver injury also influence the risk of disease development. More recently several genetic loci have been robustly associated with the risk for developing significant alcohol-related liver disease. It remains unclear whether additional risk factors are involved in the development of the clinical syndrome of alcoholic hepatitis, but the genetic evidence is suggestive.
