title: Polymorphisms in the interleukin-10 gene promoter and the risk of alcoholism and alcoholic liver disease in Caucasian Spaniard men.
abstract: Controversy surrounds the possible influence of the single nucleotide polymorphisms (SNPs) of the interleukin-10 (IL-10) gene promoter on the risk for alcoholic liver disease. Our aim was to determine whether the SNP of the IL-10 gene promoter are associated with an increased risk for alcoholism and for alcoholic liver disease in male Spaniards. The -627 C>A SNP of the IL-10 gene promoter was assessed in a cohort of 344 Caucasian Spanish men, 168 alcoholics, and 176 nonalcoholics. The alcoholic group comprised 79 individuals without liver histopathologic abnormalities and 89 patients with chronic alcoholic liver disease. The nonalcoholic group was made of 62 healthy controls and 114 patients with chronic nonalcoholic liver disease. Genotyping was performed using PCR and automatic sequencing analysis methods on white cell DNA. Genotype and allele frequencies were compared by using the chi(2) test. Overall, no differences in either genotype and allele distribution was observed when comparing the four patient categories defined (P=0.62 and P=0.33, respectively). Subset analyses showed no differences in the genotype and allele distributions between all alcoholic and all nonalcoholic subjects (P=0.55 and P=0.29, respectively). This study failed to detect significant associations of the IL-10 -627C>A SNP and alcoholism or alcoholic liver disease in a cohort of Caucasian male Spaniards.
