A few studies reported that the eradication rate was influenced by the functional polymorphism of CYP2C19 whose product metabolizes proton pomp inhibitors including lansoprazole. Methods This study examined the eradication rate among 67 participants in the polymorphism study who visited Daiko Medical Center Nagoya University from July 2004 to October 2005. The participants aged 20 to 69 years were classified into three group according to CYP2C19 genotype rapid metabolizers rM with 1 1 genotype intermediate metabolizers IM with 1 2 or 1 3 genotype and poor metabolizers pm with 2 2 2 3 or 3 3 genotype. For the genotype classification G681A 681G for 1 and 681A for 2 and G636A 636G for 1 and 636A for 3 were genotyped by PCR with confronting two-pair primers PCR-CTPP . They were also genotyped for IL-1B T-31C and1 TNF-A T-1031C by a duplex pCR-CtPp. Results The eradication rate was for RM for IM and for PM. The difference in the rate between RM and IM
