Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Chronic obstructive pulmonary disease (COPD) will become the third leading cause of death worldwide in 2020 (3.5 million patients, 16500 deaths in France). Its socio-economic cost is related to the handicap induced by the decline of the respiratory function, as well as to the occurrence of exacerbations, main causes of hospitalization and mortality. Since exacerbations are mostly infectious, a preventive strategy involves routine influenza vaccination. Although it is highly recommended in this population, there is no formal evidence of its effectiveness during COPD. While correlates of influenza vaccine efficacy exist, cellular and humoral responses to this vaccine have been poorly evaluated in these patients. This alteration of the vaccine response could also be integrated into an overall deficit of the response to a vaccine in these patients.

As influenza virus infection is one of the most important causes of death in patients with COPD, and vaccination is the best way to prevent it, it is essential to better understand the immune response in the context of vaccination in this population. The investigator's hypothesis is that there would be a global alteration of the immunological immune response in the COPD patient involving abnormalities of lymphocyte B differentiation and the effector capacity of T lymphocytes, notably through the activation of the PD1 / PDL1 axis.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

The study will be offered to patients for whom there is a prescription for influenza vaccination and DTp, COPD or non-COPD

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Patient
patient with COPD
Other: Anti-influenza and DTp pertussis vaccinations
Anti-influenza and DTp pertussis vaccinations will be performed during the visit by the clinical research nurse. The vaccine has been prescribed as part of the care either by the patient's physician (pulmonologist or general practitioner).
control group
patient without COPD
Other: Anti-influenza and DTp pertussis vaccinations
Anti-influenza and DTp pertussis vaccinations will be performed during the visit by the clinical research nurse. The vaccine has been prescribed as part of the care either by the patient's physician (pulmonologist or general practitioner).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Rate and evolution of specific antibodies and Cellular B vaccine response
Time Frame: 30 days
Rate and evolution of J30-specific antibodies according to WHO criteria Tetanus: before vaccination a rate> 0.1 IU / ml is considered protective, that is usually at a rate> 1 IU / ml after booster vaccination Influenza: antibody concentrations exceeding 0.15 μg / ml are considered protective Pertussis: anti-pertussis toxin IgG (PT) Cellular B vaccine response (plasmablast on D7)
30 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Type of Cellular T cell response
Time Frame: 15 days
Cellular T cell response (Tfh, Treg, TCD4 / TCD8 specific)
15 days
Transcriptomic analysis
Time Frame: 30 days
Transcriptomic analysis in the pre- and post-vaccination period (vaccine signature) and comparison with matched subjects
30 days
Number of Lymphocyte populations
Time Frame: 7 days
Analysis of lymphocyte populations B and T
7 days
Number of exacerbations
Time Frame: 6 months
Number of minimal, moderate and severe exacerbations within 6 months of vaccination
6 months

Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
