Trial summary

Many patients with Sickle Cell Disease (SCD) may develop Acute Chest Syndrome (ACS). ACS is usually caused by a Lower respiratory tract infection (LRTI) which may be caused by either a bacterium or a virus. Antibiotics are usually used for 7 to 10 days with no microbiological workup.

About this study

Official title: Combined Use of a Respiratory Broad Panel Multiplex PCR and Procalcitonin to Reduce Antibiotics Exposure in Adult Patients With Sickle-cell Disease Hospitalized for Acute Chest Syndrome. A Bi-centric, Open, Parallel-group, Randomized Controlled Study

Many patients with Sickle Cell Disease (SCD) may develop Acute Chest Syndrome (ACS). ACS is usually caused by a Lower respiratory tract infection (LRTI) which may be caused by either a bacterium or a virus. Antibiotics are usually used for 7 to 10 days with no microbiological workup.

The hypothesis of the study is that the identification of the microorganisms might lead to a reduction of antibiotics exposure and a better care of the patients.

We speculate that an early pathogen-directed strategy (respiratory broad panel multiplex PCR and early antibiotics interruption based on the PCT values decrease) might reduce the antibiotics exposure in SCD patients with ACS who are hospitalized and for whom an antibiotic treatment is indicated, as compared with usual care

Read the detailed description

Acute Chest Syndrome (ACS) is a frequent and severe acute complication of sickle-cell disease. It may affect 10 to 20% of hospitalized patients and is the leading cause of death. The symptoms combine a new pulmonary infiltrate and symptom(s) among fever, cough, dyspnea, expectoration, chest pain and crackles. The pathophysiology of ACS is complex and there are many interlinked aetiologies.

Lower respiratory tract infection (LRTI) is one of the most frequent aetiologies of ACS. Intracellular bacteria (Chlamydia, Mycoplasma), respiratory virus (especially respiratory syncytial virus) and pyogenes (Streptococcus pneumoniae and Staphylococcus aureus) are the most frequently identified microorganisms. Nevertheless, the clinical presentation of ACS is not helpful for the diagnosis of LRTI; the respiratory tract samples are not always collected, either because the patients do not expectorate or because the benefit-risk ratio of a fiberoptic bronchoscopy may be not advantageous. Moreover, usual diagnostic test are not enough performant.

The current practices rely on the systematic administration of antibiotics for 7 to 10 days. The efficacy and safety of alternative diagnostic and therapeutic strategies have never been evaluated in controlled clinical trial to cure ACS.

In this context, the optimisation of the microbiological documentation of ACS might enhance the use of antimicrobial drugs, reduce their duration, and limit the emergence of multidrug resistant bacteria.

Therefore, we speculate that an early pathogen-directed strategy (respiratory broad panel multiplex PCR and early antibiotics interruption based on the PCT values decrease) might reduce the antibiotics exposure in SCD patients with ACS who are hospitalized and for whom an antibiotic treatment is indicated, as compared with usual care.

Questions about this trial

What is this clinical trial studying?

A study testing Intervention: Combined use of a respiratory broad panel multiplex PCR and procalcitonin in people with Acute Chest Syndrome and Sickle Cell Disease, run by Assistance Publique - Hôpitaux de Paris 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 4 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 24 Mar 2025. 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?

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?

to compare the antibiotics exposure at 28 days (D28) after the diagnosis of ACS between the two strategies (time frame: Day 28). 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 NCT03919266, 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 24 Mar 2025.
