Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Individuals who were tested for COVID-19 using real-time reverse transcriptase PCR assay of nasal and pharyngeal swabs were included. Data were obtained from the Korean national health insurance claims-based database (COVID-19 research dataset). Individuals with a Record of a new prescription of NSAID within 1 month of the test date were excluded because NSAID users for early pneumonia symptoms may initiated for PPIs or H2 blockers.

Who may be able to join

  • Individuals who were tested for COVID-19 using real-time reverse transcriptase PCR assay of nasal and pharyngeal swabs

Who cannot join

  • Record of a new prescription of non-steroidal anti-inflammatory drugs (NSAID) within 1 month of the test date
  • Patients who died within 48 hours after test.

About this study

Official title: Effect of Histamine 2 Receptor Antagonist (H2RA) and Proton Pump Inhibitor (PPI) on the Positivity Rates and Clinical Outcomes of Coronavirus Disease-19 (COVID-19).

This retrospective cohort study aims to evaluate the effect of proton pump inhibitor (PPI) or histamine-2 receptor antagonist (H2RA) on the clinical outcomes and positivity rates of Coronavirus Disease-19 (COVID-19).

Read the detailed description

Previous researches on the association between the use of PPI and H2RA and the treatment and prevention of COVID-19 have reported inconsistent findings. This study aimed to evaluate the effect of H2 receptor antagonists and proton pump inhibitors on the clinical outcomes and positivity rates of COVID-19 using the Korean National Health Insurance (NHI) data. This is a retrospective cohort study using the NHI COVID-19 dataset, which includes health insurance data of individuals who underwent COVID-19 PCR test in South Korea. This study aims to evaluate the effect of the use of PPI and H2RA on the positivity rates and clinical outcomes of COVID-19.

What is being measured

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

  1. COVID-19 test positivity

    Test positivity rates for COVID-19 nasopharyngeal polymerase chain reaction (PCR): number of participants diagnosed with COVID-19 compared to the number participants who were tested for COVID-19

    Measured: Through test completion, an average of 1 day

  2. Mortality

    Mortality of participants who died after diagnosis of COVID-19 (during the hospitalization or after discharge)

    Measured: 60 days

Secondary outcomes (4)
  1. Intensive care unit admission rate

    Intensive care unit admission rate of patients who were diagnosed with COVID-19

    Measured: 60 days

  2. Mechanical ventilator application rate

    Mechanical ventilator application rate of patients who were diagnosed with COVID-19

    Measured: 60 days

  3. Oxygen apply rate (Nasal prong, Facial Mask, High flow nasal cannula)

    Oxygen apply (Nasal prong, Facial Mask, High flow nasal cannula) rates of patients who were diagnosed with COVID-19

    Measured: 60 days

  4. Rates of vasopressor and inotrope use

    Rates of vasopressor and inotrope use of patients who were diagnosed with COVID-19

    Measured: 60 days

Questions about this trial

What is this clinical trial studying?

An observational study of COVID-19, run by Seoul National University Hospital at 1 site in South Korea.

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 2 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 29 Nov 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 South Korea. 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?

COVID-19 test positivity (time frame: Through test completion, an average of 1 day). The study lists 2 primary outcomes in all. 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 29 Nov 2024.
