NCT04462133

Brief Summary

The efficacy of the current standard triple therapy is at an unacceptably low level. Resistance to antibiotics is suspected to be the major cause of the low efficacy of standard triple therapy. Point mutations in the 23S rRNA gene are known to be the primary mechanism of clarithromycin resistance against H pylori. Recently, a point mutation detection kit using a dual-priming oligonucleotide (DPO)-based multiplex polymerase chain reaction (PCR) assay was introduced and made commercially available. The primary goal of our study was to compare the eradication rates of empirical therapy and tailored therapy. Specifically we examined the eradication rates of 7-d, 14-d empirical therapy with 7-d, 14-d tailored therapy. Our secondary goal was to examine the adverse events of each treatment, cost effectiveness of each treatment methods, and accuracy of DPO-PCR for detecting H. pylori resistance.

Outcome Measures

Primary Outcomes (1)

  • Eradication success

    H. pylori eradication success based on urea breath test

    8-12 weeks after eradication

Study Arms (2)

Empirical therapy for H. pylori infection

ACTIVE COMPARATOR

The empirical group receives triple therapy of 7 or 14 days for H. pylori eradication

Diagnostic Test: Dual-priming oligonucleotide-based multiplex polymerase chain reaction (DPO-PCR)

Tailored therapy for H. pylori infection

EXPERIMENTAL

The tailored therapy group receives eradication regimens based on their DPO-PCR results. Triple therapy of 7 or 14 days for clarithromycin sensitive patients based on DPO-PCR and bismuth quadruple therapy of 7 or 14 days for clarithromycin resistant patients based on DPO-PCR.

Diagnostic Test: Dual-priming oligonucleotide-based multiplex polymerase chain reaction (DPO-PCR)
