Long-term Alterations of Host-microbiome Interactions and Cardiovascular and Respiratory Diseases Progression After Pneumonia

Long-term Alterations of Host-microbiome Interactions and Cardiovascular and Respiratory Diseases Progression After Pneumonia - the HOMI-LUNG Project - Hospital-Acquired-Pneumonia


Sponsor

Nantes University Hospital

Enrollment

300 participants

Start Date

Jan 2, 2025

Study Type

INTERVENTIONAL

Conditions

Summary

The HOMI-LUNG - HAP study is part of the HOMI-LUNG project, funded by the Horizon Europe program. The "HOMI-LUNG" project is an international, interdisciplinary project that aims to better understand the causal links between respiratory tract infections (i.e. pneumonia) and the progression of cardiovascular disease. More specifically, the project aims to quantify the burden of cardiovascular disease after pneumonia and assess patients\' acceptability of long-term health alterations, as well as to define pneumonia endotypes with distinct pathobiological mechanisms associated with exacerbation of cardiovascular disease.

Interventions

OTHERBlood samples

Four blood samples will be taken outside standard care for groups A, B, C and D: at inclusion, M6, M18 and M30 (only at inclusion for group C).

OTHEROropharyngeal swabs

An oropharyngeal swab will be taken to analyze patients\' upper airway microbiome at inclusion, M6, M18 and M30.

OTHERCalcium score (CT scan)

A calcium score will be taken at 30 months, to assess individual cardiovascular risk.

OTHERECG

Performed at inclusion, M6, M18 and M30

OTHERCardiopulmonary exercise test, spirometry, plethysmography, pulmonary absorption of carbon monoxide in a single inspiration, and 6-minute walk test

Cardiopulmonary exercise test, spirometry, plethysmography, pulmonary absorption of carbon monoxide in a single inspiration, and 6-minute walk test: These tests will be performed consecutively for 2 hours at inclusion (6-minute walk test only), at M6 and at M30. These tests will be performed to assess respiratory and cardiac function.
