We investigated the associations between the host HLA-DQ variation and the prevalence of H ruli in
the Indonesian population with an H. pylori-infected level of 11.2% in people living in the Bukhara
region. It was noted that individuals carrying the DQB1 * 0401 genotypes are at significantly greater
risk of developing H infection. .lori compared to individuals with the DQB1 0301 genotypes. The DQA1
or DQB1 haplotypes were not associated with H. pulori infection.
