Aim: To find the ADH3 genotypes in the Polish population likely to be responsible for higher susceptibility to alcohol disease of the liver and chronic alcohol pancreatitis. Method: The ADH3 genotype and ADH3*1 and ADH3*2 alleles frequencies were examined in 198 patients. Genotyping of the ADH3 was performed using PCR–restriction fragment length polymorphism methods on a white cell DNA. Results: The genotype ADH3*1/ADH3*1 was found to be significantly more frequent in alcohol abusers compared with non-drinkers. The examinations of the group of alcohol abusers showed that the genotype ADH3*2/ADH3*2 occurred statistically significantly less frequently in patients with chronic pancreatitis than in those without alimentary lesions (healthy drinkers). The alleles ADH3*1 and genotype ADH3*1/ADH3*1 were significantly more frequent in men than in women, whereas alleles ADH3*2 and genotype ADH3*2/ADH3*2 were more common in women. Conclusions: The genotype ADH3*2/ADH3*2 is likely to be a protective factor for chronic pancreatitis. Variations in ADH3 genotypes may account for some of the differences in prevalence of alcohol dependence between genders in the Polish population.
