Prognosis of Klebsiella ESBL Sepsis: Role of 2-HYDRoxy-myristate in Endotoxin Structure
An observational study of Klebsiella Infections, run by Fondation Hôpital Saint-Joseph at 1 site in France.
Trial summary
Infections constitute a multiple and heterogeneous set of pathologies, and the first cause of mortality worldwide. Among them, sepsis is a more recent nosological entity, including the most severe forms of acute infectious pathologies, its frequency increasing considerably over time. Read more about this study

About this study
Infections constitute a multiple and heterogeneous set of pathologies, and the first cause of mortality worldwide. Among them, sepsis is a more recent nosological entity, including the most severe forms of acute infectious pathologies, its frequency increasing considerably over time. It is considered to be the cause of more than 27 million deaths per year, more than 4,000 deaths per day in the United States and about 200 deaths per day in intensive care units in France.
The occurrence of hemodynamic failure within visceral damage is a poor prognostic factor, the lethality in this situation can reach 60% of affected patients. The amount of organ dysfunction is also prognostic. More worryingly, the initial mortality is aggravated by the persistence of the negative evolution after hospital treatment, the 5-year prognosis being significantly more severe in the population of patients treated for sepsis than in the general population, particularly in the case of respiratory or cardiovascular damage during the stay in intensive care. The most frequent causes of these severe infections in the ICU are lower respiratory infections, particularly pneumonia acquired under mechanical ventilation, urinary tract infections and digestive tract infections.

Sepsis corresponds to an infection of particular severity, which results in the association of organ failures, the type and severity of which vary according to the patient, the origin of the infection and the pathogen responsible. The severity of the picture will require specific management and may necessitate the introduction of organ supplements or even lead to death in the most serious forms.
Infections by enterobacteria and in particular Klebsiella spp. are frequent in the intensive care unit. The association with antibiotic resistance and especially with ESBL production is a daily clinical situation. During these infections, the prognosis is variable, sometimes very poor, without it being possible to determine whether this evolution is due to antibiotic resistance or to the virulence of the pathogen. The objective of this work is to study the structure of lipid A of ESBL-producing Klebsiella strains responsible for nosocomial infections. This study is part of the "EVENT" protocols of which it is an ancillary analysis.
The objective of this study is to evaluate the role of the presence of 2-hydroxymyristate within lipid A of the lipopolysaccharide in the prognosis of ESBL-producing Klebsiella infections in the ICU. The secondary objectives correspond to the evaluation of the vital prognosis according to the infected organ (lung, kidney, digestive system), and the presence of 2-hydroxymyristate and the risk of bacteremia.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Among them, sepsis is a more recent nosological entity, including the most severe forms of acute infectious pathologies, its frequency increasing considerably over time. It is considered to be the cause of more than 27 million deaths per year, more than 4,000 deaths per day in the United States and about 200 deaths per day in intensive care units in France.

Questions about this trial
What is this clinical trial studying?
An observational study of Klebsiella Infections, run by Fondation Hôpital Saint-Joseph 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 5 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 7 Mar 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?
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?
Role of 2-hydroxymyristate within lipid A of lipopolysaccharide in the prognosis of ESBL-producing Klebsiella infections in the ICU (time frame: Day 128). 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 NCT05193045, which also lists 7 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 7 Mar 2023.
