About this study

Official title: Epidemiologic Surveillance to Assess Trends in Acute Hepatitis A Among Children in Panama

The purpose of this study is to collect epidemiological and clinical data to assess the vaccine impact and occurrence of confirmed acute hepatitis A cases in sentinel hospitals after the introduction of Havrix™ into the Expanded Program of Immunization.

Read the detailed description

This is an observational, prospective, multi-centre, sentinel based study in 3 hospitals in Panama. Hospitals are selected based on population density or hepatitis A disease burden.

The Pan American Health Organization (PAHO) definition for a possible case of acute hepatitis A are used for subjects aged between >1 month and <15 years.

Data regarding clinical and epidemiologic information are collected and serum samples are collected to test hepatitis A markers and determine if infection with hepatitis A virus has recently occurred.

Surveillance will be for a period of approximately 2.5 years from the date of study initiation.

What is being measured

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

  1. Occurrence of confirmed acute hepatitis A cases identified in the selected sentinel hospitals during the study period by age group, area of residence and year of surveillance

    Measured: average time-frame: 2.5 years

Secondary outcomes (3)
  1. Occurrence of possible and probable cases of acute hepatitis A virus by age group, area of residence and year of surveillance

    Measured: average time-frame: 2.5 years

  2. Risk factors for confirmed cases of acute hepatitis A

    Measured: average time-frame: 2.5 years

  3. Frequency of different clinical signs and symptoms of hepatitis A

    Measured: average time-frame: 2.5 years

Questions about this trial

What is this clinical trial studying?

An observational study of Acute Hepatitis A and Hepatitis, run by GlaxoSmithKline at 1 site in Panama.

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

The record says: finished, as of the sponsor's last update on 22 Nov 2012. 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 Panama. 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?

Occurrence of confirmed acute hepatitis A cases identified in the selected sentinel hospitals during the study period by age group, area of residence and year of surveillance (time frame: average time-frame: 2.5 years). 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 NCT01159925, 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Nov 2012; AzTrials last refreshed its copy on 6 Nov 2026.
