Trial summary

About this study

Official title: Contribution of the Sonication of Implants to the Diagnosis of Joint Prosthesis Infection: Retrospective Cohort Study From 2019 to 2022 at the University Hospitals of Strasbourg

Studies on sonication suffer from a heterogeneity which makes their analysis complex, due to the absence of a gold standard allowing positive cases to be defined unequivocally. Thus, the sensitivity of the technique has been assessed on cases defined in different ways, which makes the studies difficult to compare (number of samples taken, number of positive samples, variable duration of culture, etc.). It should nevertheless be noted that the majority of the series conclude with a higher sensitivity than that of standard samples, in particular in the event of a strain with difficult growth (Cutibacterium acnes, deficient Streptococci) or in the event of prior antibiotic therapy.

In the absence of a comparative reference allowing to conclude on the intrinsic performances of sonication as a diagnostic test, it seems interesting to evaluate its contribution in current practice, in particular in the difficult cases where the standard culture does not make it possible to fulfill the criterion. major (zero or only one positive sample). To the knowledge of the investigators, there is no study of this kind, which could make it possible to specify the place of this technique in the diagnostic procedure and to improve the care of patients.

What is being measured

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

  1. Proportion of subjects with only a peri-prosthetic sample whose culture is positive, and for whom the culture of the sonication fluid is positive and consistent with this first sample, with an objective of >5%.

    Measured: 4 years after implant

Questions about this trial

What is this clinical trial studying?

An observational study of Prosthesis Related Infection, run by University Hospital, Strasbourg, France at 1 site 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 5 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 22 Sep 2023. 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 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?

Results are not available in the source record.

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

Contact Cécile RONDE-OUSTAU, MD (33 3 68 76 50 62, cecile.ronde-oustau@chru-strasbourg.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of subjects with only a peri-prosthetic sample whose culture is positive, and for whom the culture of the sonication fluid is positive and consistent with this first sample, with an objective of >5%. (time frame: 4 years after implant). 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 22 Sep 2023.
