    Helicobacter pylori (Hp) infection is officially recognized as an infectious disease and is now included in the 11th revision of the International Classification of
    Diseases.

    The 6th edition of the Maastricht/Florence 2021 Consensus Report covers progress in the management of Hp infection, with guidance on the management of Hp infection
    .
    The
    main points of the treatment part of the consensus are summarized below
    .

    Statement 1In
    antibiotic stewardship, routine susceptibility testing (molecular or cultured) is recommended, even before initial treatment
    .
    However, the popularization of this antibiotic-sensitivity-guided strategy in routine clinical practice remains to be determined
    .

    (Consensus level: 91%; Evidence level: D2) Statement 2If
    individual susceptibility testing is not possible, the recommended first-line treatment is bismuth quadruple therapy (BQT)

    in settings with high clarithromycin resistance (> 15%) or unknown resistance rates.
    If not available, non-bismuth tetraplex therapy may be considered
    .

    (Consensus level: 92%; Certainty of evidence: B1)
    states that the duration of bismuth quadruple therapy should be 14 days, unless 10 days of equivalently effective therapy
    is available
    .

    (Consensus level: 85%; Certainty of evidence: D2) Statement 4
    concomitant therapy (simultaneous administration of PPIs, amoxicillin, clarithromycin, and nitroimidazoles)
    should be the preferred regimen for non-bismuth quadruple therapy because of its reproducible efficacy and low
    complexity compared with sequential and mixed therapies.
    PPI, proton pump inhibitor
    (consensus level: 94%; Evidence level: B1)
    stated that the recommended course of non-bismuth
    quadruple therapy was 14 days
    .

    (Consensus level: 100%; Evidence level: D2)
    Statement 6In
    areas with low rates of clarithromycin resistance, bismuth quadruple therapy or clarithromycin-containing triple therapy may be recommended as first-line empiric therapy
    if local studies prove effective.

    (Consensus level: 94%; Evidence level: B1) Statement 7
    :
    The recommended course of PPI-clarithromycin-based triple therapy is 14 days
    .

    (Consensus level: 100%; Certainty of evidence: B1)
    stated that 8
    high-dose PPIs twice daily improve the efficacy
    of triple therapy.
    It is unclear whether twice-daily high-dose PPIs improve the efficacy
    of quadruple therapy.

    (Consensus level: 97%; Evidence level: C2) stating that 9-potassium-competitive
    acid blocker (P-CAB)
    -antibiotic dual therapy is superior or inferior to traditional PPI-based triple therapy in first- and second-line therapy, Superior
    in patients with evidence of antibiotic-resistant infection.

    (Consensus level: 100%; Level of evidence: B2)
    Statement 10
    Empiric second-line and salvage treatment should be guided by local antibiotic resistance models assessed by susceptibility testing and eradication rates to optimise treatment success
    .

    (Consensus level: 94%; Evidence level: D2) After stating that 11
    bismuth quadruple therapy has failed, either a fluoroquinolone-containing quadruple (or triple)
    or a high-dose PPI-amoxicillin dual therapy
    is recommended.
    In the setting of high fluoroquinolone resistance, bismuth may be used
    in combination with other antibiotics or rifabutin.

    (Consensus level: 83%; Evidence level: C2) states that after
    failure of PPI-clarithromycin-amoxicillin, bismuth quadruple therapy, fluoroquinolone quadruple (or triple)
    therapy, or high doses are recommended PPI-amoxicillin dual therapy is used as a second-line treatment
    .

    (Consensus level: 84%; Evidence level: C2) After statement 13
    of non-bismuth quadruple therapy, bismuth quadruple therapy or fluoroquinolone-containing quadruple (or triple)
    therapy is recommended
    .
    High-dose PPI-amoxicillin dual therapy
    may also be considered.

    (Consensus level: 87%; Evidence level: C2)
    stated that fluoroquinolones-containing regimens are recommended after failure of first-line triplex therapy containing clarithromycin or non-bismuth
    quadruple therapy or second-line bismuth quadruple therapy
    。 In areas of high fluoroquinolone resistance, dual bismuth therapy with other antibiotics, remedial therapy containing rifabutin, or high-dose PPI-amoxicillin dual therapy
    should be considered.

    (Consensus level: 86%; Evidence level: B2)
    states that 15
    remedial treatment with bismuth quadruple therapy is recommended after failure of first-line triple therapy containing clarithromycin or non-bismuth quadruple therapy, and second-line fluoroquinolone-containing therapy
    .
    If bismuth is not available, a high-dose PPI-amoxicillin dual or rifabutine-containing regimen
    may be considered.

    (Consensus level: 84%; Evidence level: B2)
    states that after failure
    of first-line bismuth-quadruple therapy and second-line fluoroquinolone-containing therapy, only hyporesistance to clarithromycin (<15%) is recommended ) is treated with triad or quadruple regimens containing clarithromycin<b20>.
    Otherwise, a high-dose PPI-amoxicillin duo should be usedor regimens containing rifabutin or bismuth in combination with other antibiotics
    .

    (Consensus level: 90%; Evidence level: C2) Statement 17
    For penicillin-allergic patients, bismuth quadruple therapy (PPI-bismuth-tetracycline-metronidazole)
    is recommended first-line
    .
    Empiric salvage therapy with bismuth quadruple therapy (if not previously used) and fluoroquinolone-containing therapy is recommended in the second line
    .

    (Consensus level: 85%; Evidence level: C2).
