Vaccine Response in Patient With Sepsis (Vaccis)
Evaluation of Prevenar 13's Vaccine Response in Patients Hospitalized in Infectious Disease Department for Sepsis
Vaccination is established as an effective means of individual and collective protection. Hospitalization is an opportunity not to be missed to catch up on vaccinations in certain fragile patients. Patients hospitalized in infectious diseases are generally treated for an acute or chronic infection that can modulate their immunity and therefore their vaccine response. Current vaccine immunogenicity data in immunocompromised patients support a lower percentage of responders than observed in immunocompetent patients.
There is little data to assess the vaccine response (VR) in patients treated for an infection (bacteremia, pneumonia, urinary tract infection, etc.). In order to respond to this problem, the investigators have chosen to evaluate the vaccine response to Prevenar 13 (PCV13), a conjugate vaccine recommended as a prime-boost since 2013, which must be followed by a vaccination at 2 months with Pneumovax, an unconjugated vaccine of 23 valences.
Anti-pneumococcal vaccine coverage in frail people (immunocompromised, heart failure, respiratory failure, kidney failure, diabetics) remains low and is estimated at less than 10% in 2011, while the bacteria is responsible for severe invasive infections.
In total, the investigators would like to study the vaccine response at 1 month of vaccination with Prevenar 13 in patients hospitalized in infectious disease for sepsis, in order to demonstrate the benefit of vaccination per hospitalization.

Other: Vaccination in patient with sepsis
|
For patients with sepsis who require vaccination during hospitalization, we will analyze the immunogenicity of pneumococcal conjugate vaccine (PCV13) by taking blood samples

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Assess vaccine response rate at 1 month in patients with sepsis, negative to Covid-19, with an indication for pneumococcal vaccination
Time Frame: at 1 month
|
PCV13 vaccine response rate will be measured by an ELISA method certified by WHO.
Immunoglobulin G level measurements will be performed on 13 pneumococcal vaccine serotypes to analyze the vaccine response rate of patients.
|
at 1 month
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Evaluate cellular immunity in patients with sepsis, negative to Covid-19, with an indication for pneumococcal vaccination, at inclusion
Time Frame: At inclusion
|
Cellular immunity will be assessed by a gamma interferon level, after non-specific stimulation of T and NK lymphocytes in the PMBC surnageant of patients cultured before vaccination (at inclusion).
This level will be determined with the QFM (QuantiFERON Monitor®) test.
|
At inclusion
|
Identifiy the threshold of cellular immunity by the rate of gamma interferon (IFN) before vaccination (at inclusion) in patients with sepsis, negative to Covid-19, with an indication for pneumococcal vaccination
Time Frame: At inclusion
|
Cellular immunity will be assessed by a gamma interferon level, after non-specific stimulation of T and NK lymphocytes in the PMBC surnageant of patients cultured before vaccination (at inclusion).
This level will be determined with the QFM (QuantiFERON Monitor®) test.
|
At inclusion
|
Identify vaccine non-response risk factors at 1 month after vaccination, in patients with sepsis, negative to Covid-19, with an indication for pneumococcal vaccination
Time Frame: at 1 month
|
Anamnestic and clinical factors of vaccine non-response will be studied
|
at 1 month
|
Assess the diagnostic performance (validity and reliability) of the vaccine response of PV13 at 1 month, in patients with sepsis, negative to Covid-19, with an indication for pneumococcal vaccination, assessed by an IgG VaccZymeTM anti-PCP ELISA method.
Time Frame: at 1 month
|
Diagnostic performance (validity and reliability) of the vaccine response of PV13 will be assessed by an IgG VaccZymeTM anti-PCP ELISA method from The Binding site and the WHO validated ELISA method.
Vaccinal response level from both methods will be compared.
