  • No healthy volunteers
  • Adult, Older adult

Study population: Hospitalized adult patients suspected of infective endocarditis

Who may be able to join

  • Patients older than 18 years
  • Suspected endocarditis: Patients with Duke-Li-ESC 2015 classification as a major morphological criterion or at least two minor criteria, other than a microbiological criterion, will be considered suspicious of infectious endocarditis.
  • Not objecting to their inclusion in the study after delivery and explanation of the information form.
  • Absence of microbiological documentation sought or available at the time of inclusion (a patient having already had negative blood cultures or being identified during the screening can be included).

Who cannot join

  • Antibiotherapy adapted to a situation of endocarditis, introduced more than 24 hours or stopped for less than 7 days in case of therapeutic window.
  • Any previous antibiotic therapy in the 7 days preceding the inclusion leading to an improvement in the clinical symptomatology.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Blood CultureProcedure or surgery

    For each patient, one single high volume blood culture (3 aerobic and 3 anaerobic of 8 to 10 mL each, numbered), and then 2 samples of 16 to 20 mL (one aerobic bottle and one anaerobic for each sample).

Study groups in NCT03153384
Study groupRoleWhat they receive
one both experimental and control armEach patient experiences two methods of blood cultures.
Receives: Procedure: Blood Culture

What is being measured

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

  1. Compared performance of a single high volume blood culture vs. multiple blood culture of usual volume for the diagnosis of infective endocarditis

    Sensitivity/Specificity/Accuracy of positive bloodculture sets vs. final diagnosis assessed by the medical team (gold standard)

    Measured: At the end of the hospitalization, or at the time of death if occurred during hospitalization; i.e. an average of 6 weeks after the inclusion

Secondary outcomes (3)
  1. Diagnostic performance of the single high volume blood culture for the diagnosis of infective endocarditis

    according to the level of suspicion of infective endocarditis, the type of microorganism involved, the underlying cardiopathy.

    Measured: At the end of the hospitalization, or at the time of death if occurred during hospitalization; i.e. an average of 6 weeks after the inclusion

  2. Measuring the nursing time required for both sampling methods.

    Time for blood culture setting, processing and sending

    Measured: At T0, i.e. at the inclusion of the patient

  3. Diagnosis of infective endocarditis: confirmed, possible or excluded

    Applying the Classification of Duke-Li according to the modified diagnostic criteria of the European Society of Cardiology Recommendations 2015.

    Measured: At the end of the hospitalization, or at the time of death if occurred during hospitalization; i.e. an average of 6 weeks after the inclusion

Questions about this trial

What is this clinical trial studying?

An observational study of Bacteremia and Infective Endocarditis, run by Central Hospital, Nancy, France at 8 sites in France.

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 3 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 19 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in France. 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?

Compared performance of a single high volume blood culture vs. multiple blood culture of usual volume for the diagnosis of infective endocarditis (time frame: At the end of the hospitalization, or at the time of death if occurred during hospitalization; i.e. an average of 6 weeks after the inclusion). 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 NCT03153384, which also lists 4 linked publications.

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 19 Mar 2024.
