About this study

Official title: Effect of Histamine-2 Receptor Antagonists on the Microbiome of Full Term Infants

The changes in the organisms making up the gut microbiota in infants who are taking anti-acid reflux medications (histamine 2 receptor antagonists) as compared to infants who are not taking these medications is not well-studied or understood. Whether these medications change the gut microbiota and microbiome, and what that change may imply for children on these medications, is the focus of this study.

Read the detailed description

Gut microbiota dysbiosis is associated with diseases ranging from localized gastrointestinal disorders to neurologic, respiratory, metabolic, hepatic, and cardiovascular illnesses. The microbial colonization of the infant gut is known to play a key role in immunologic and metabolic pathways impacting on human health. Disruptions during the complex process of microbial colonization have been shown to increase disease susceptibility during life. A variety of factors are known to influence the gut microbiota, including mode of delivery of neonate, host genetic factors, hose immune response, diet, xenobiotics and other drugs, infections, and environmental microbial exposures.

The diagnosis of gastroesophageal reflux disease in the infant population has increased during the past two decades. Acid suppression medications are used commonly in infants for gastroesophageal reflux disease and other acid-related conditions despite little evidence of their efficacy. Multiple studies have shown adverse effects in pediatric patients using either proton pump inhibitors or H2 receptor antagonists, the two classes of acid suppression medications that are most frequently used in children. Some of these adverse effects may result from alterations in the microbiome caused by these medications. Prior studies have demonstrated significant changes in microbial composition of both gastric and intestinal microbiota with proton pump inhibitor use (5), but to the investigators' knowledge, no prior studies have looked at the effect of H2 receptor antagonists on the microbiome in healthy, full term infants.

Questions about this trial

What is this clinical trial studying?

An observational study of GERD and Dysbiosis, run by Nemours Children's Clinic at 1 site in United States.

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 3 inclusion and 6 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 12 Jun 2024. 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 United States. 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?

Microbiome taxa (time frame: At time of sampling - once at enrollment). 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 12 Jun 2024.
