About this study

Official title: A Comparison of Four Different Treatment Regimens as the First-line Treatment of Helicobacter Pylori in Chinese Children and Investigation of Resistance and Impact factors-a Multicenter Study

With the resistance of Helicobacter pylori increasing, low and unsatisfactory eradication rate (64%) have been observed with standard triple therapy in European children. Which regimen is appropriate for Chinese children? There is no large scale, multi center studies in China about treatment, CYP2C19 gene polymorphism, resistance rate and resistance genotype. Investigators want to perform a research to compare four different treatment regimens(triple therapy, sequential therapy, bismuth quadruple therapy and concomitant therapy)as the first-line treatment of Helicobacter pylori in Chinese children and investigation of resistance, impact factors and changes of microbiota after the therapy. The results of the study will provide theoretical basis to make the new guideline of diagnosis and therapy of Helicobacter pylori in Chinese children. It advance instruct and norm the clinical practice for Chinese pediatrician to increase the cure rate of Helicobacter pylori and decrease the resistance.

Read the detailed description

Eligible children were randomly divided into four groups: standard triple therapy, sequential therapy, bismuth quadruple therapy and concomitant therapy. The course of treatment is 14 days. The primary outcome measure was the Hp eradication rate at 4-6 weeks after completion of treatment which was confirmed by a negative of 13 UBT. Secondary outcome measures included side effects, impact factor and changes of microbiome after the therapy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 13C-UBT

    13C-UBT was used to determine whether Hp treatments was successful

    Measured: 13C-UBT was assessed at 4-6 weeks after completion of therapy

Secondary outcomes (8)
  1. side effects

    such as diarrea,rash,dark stool

    Measured: assess at 2,4-6weeks after completion of the therapy

  2. changes of Shannon diversity indices for gut microbiome

    changes of the Shannon diversity indices

    Measured: assess at 0,2,4-6weeks after completion of the therapy

  3. changes of OTU for gut microbiome

    changes of OTU

    Measured: assess at 0,2,4-6weeks after completion of the therapy

  4. changes of abundances for gut microbiome

    changes of abundances of the bacteria

    Measured: assess at ,2,4-6weeks after completion of the therapy

  5. CYP2C19 gene that impact the metabolism of PPI

    CYP2C19 gene polymorphism

    Measured: detect the gene before the therapy

  6. virulence gene-cagA

    cagA

    Measured: detect the gene before the therapy

  7. virulence gene-vacA

    vacA

    Measured: detect the gene before the therapy

  8. patient compliance

    good compliance is defined as taking more than 80% drugs

    Measured: assess compliance 2 weeks after the therapy

Questions about this trial

What is this clinical trial studying?

A study testing triple therapy, sequential therapy and bismuth quadruple therapy in people with Helicobacter Infections, run by Ying HUANG at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 28 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Ying Zhou, master (13917394900, nnyyhhs@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

13C-UBT (time frame: 13C-UBT was assessed at 4-6 weeks after completion of therapy). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03365609, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
