Eighty two @entity1 with chronic @entity110 and 17 @entity1 with @entity9586 chronica multiformis were referred to our department from October 2004 to February 2007 and were tested for @entity1534 @entity1534 antigen using the polyclonal H.  @entity1534 stool antigen test (enzyme-linked immunosorbent assay method). H.  @entity1534 antigen was detected in 25 (30.5%) of the 82 @entity1 with chronic @entity110 and in 10 (58.8%) of the 17 @entity1 with @entity9586 chronica multiformis. Those findings were not significantly higher than the positive rate for H.  @entity1534 stool antigen in healthy age-matched controls. In @entity1 positive for H.  @entity1534 antigen, seven of the 25 with chronic @entity110 had complications of @entity3621 (six @entity1 ) or @entity2275 (one @entity1 ). Three of the 10 @entity1 with @entity9586 chronica multiformis had complications of @entity3621 (two @entity1 ) or @entity2275 (one @entity1 ). We examined the therapeutic efficacy of antibacterial treatment for the 17 @entity1 with chronic @entity110 and the eight @entity1 with @entity9586 chronica multiformis who were positive for H.  @entity1534 antigen and accepted the treatment based on informed consent. We evaluated the effectiveness of treatment by scoring the skin conditions and by using the Skindex-16, a measure of quality of life. The eradication therapy for @entity1534 was more effective for treating @entity9586 chronica multiformis and the skin symptoms started to improve within 3-14   days after the therapy. However, that therapy was not always effective for treating chronic @entity110 . We suggest that @entity1534 may be an important pathogenetic factor, especially for @entity9586 chronica multiformis, and that eradication therapy should be considered to treat intractable cases.
