Trial summary

Helicobacter Pylori (HP) is one of the most common pathogens in humans. This infection can present in children with abdominal pain, vomiting and iron deficiency. The treatment is usually empiric and includes antibiotic treatment usually Amoxycillin and Clarithromycin or Metronidazole. Read more about this study

About this study

Helicobacter Pylori (HP) is one of the most common pathogens in humans. This infection can present in children with abdominal pain, vomiting and iron deficiency. The treatment is usually empiric and includes antibiotic treatment usually Amoxycillin and Clarithromycin or Metronidazole. Between 40 to 70 % of the pathogens are resistant to those drugs, and it is important to characterize the specific sensitivity of the pathogens in any specific area and in pediatric population. The aims of this study is to assess the sensitivity of HP in pediatric population in Northern Israel.

Read the detailed description

The aim of our prospective study is to investigate the rate of H pylori resistant strains to antibiotic treatment including Amoxicillin, Clarithromycin, Metronidazole, Tetracycline and Quinolones in pediatric population in Ha-Emek medical center, Afula. The second aim was to determine if in vitro resistance is being reflected in vivo too.

Should the investigators find high rates of H pylori resistance to Clarithromycin, the investigators will have to reconsider the recommendation to use Clarithromycin as the first line treatment for H pylori.

Our research group will conclude 100 children in the ages of 1-18 years, evaluated for recurrent abdominal pain, iron deficiency anemia, failure to thrive by an upper endoscopy, biopsy specimens taken for a rapid urease test, for histology, for culture and for antibiotic susceptibility testing.

Biopsy specimens for histology will be fixed in formalin, embedded in paraffin and sectioned and stained with hematoxylin and eosin.

The microbiological workup will include an imprint of the biopsy on a slide followed by a gram stain for the purpose of demonstrating H. pylori in situ. Further the biopsies will be streaked out on chocolate agar, Sheep blood agar and H. pylori selective agar supplemented with Polymixin to suppress possible contaminants.

4 days of incubation in a micro aerophilic atmosphere will follow . Susceptibility testing of H pylori will be performed with E test on Mueller Hinton agar supplemented with defibrinated sheep blood using a MacFalrland 3.0 density of a bacterial suspension. Reading the susceptibility will take place following 72 hours of incubation in a micro aerophilic atmosphere.

Questions about this trial

What is this clinical trial studying?

An observational study of Abdominal Pain and Children, run by HaEmek Medical Center, Israel at 1 site in Israel.

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 4 inclusion and 0 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: finished, as of the sponsor's last update on 1 Sep 2015. 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 Israel. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Resistance of specific organism to antibiotics (time frame: Two weeks from the culture). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Sep 2015; AzTrials last refreshed its copy on 8 Nov 2026.
