Bismuth containing quadruple therapy versus tailored therapy as first-line treatments for infection in a high clarithromycin resistance area.

Background: Increasing clarithromycin resistance has led to the need for an alternative first-line therapy for the eradication of () in Korea, and bismuth containing quadruple therapy (BQT) and tailored therapy (TT) have been proposed as alternative regimens. The aim of this study was to compare the eradication rates of BQT and TT as first-line eradication therapies.

Methods: infection was diagnosed using the rapid urease test or dual-priming oligonucleotide-based multiplex polymerase chain reaction (DPO-PCR) during endoscopy.
