Project description
Microbiome-guided treatment for pneumonia
Hospital-acquired pneumonia is one of the most common and deadly infections worldwide. However, current treatment approaches succeed in fewer than 60 % of cases. A growing body of evidence suggests that the lung microbiome – the community of microorganisms inhabiting the respiratory tract – is directly linked to disease progression. With the support of the Marie Skłodowska-Curie Actions programme, the MATRICS project investigates whether lung microbiome signatures can reveal distinct subtypes of hospital-acquired pneumonia that require tailored therapeutic strategies. Using longitudinal microbiome data from international patient cohorts and an ongoing clinical trial, researchers will develop a microbiome-based classification model. This will provide the opportunity to predict treatment responses and guide personalised pneumonia care.
Objective
Hospital-acquired pneumonia is the second most frequent nosocomial infection in the world, leading to high mortality and morbidity. Their management is standardised and targets the dominant bacteria identified on sample culture. However, this “one-size-fits-all” approach leads to a treatment success rate that rarely goes beyond 60%, suggesting a knowledge gap in the underlying mechanisms. Recent discoveries highlighted that hospital-acquired pneumonia pathophysiology involved several actors, notably a rich and diverse respiratory microbiota with complex dynamics, that yet remains overlooked. Despite recent innovative therapies, treating pneumonia as a homogenous disease without taking into account the microbiota diversity, will lead to negative and unconclusive results. The MATRICS project aims at demonstrating, using lung microbiota signature and dynamics, that hospital-acquired pneumonia is not a homogeneous disease and should thus benefit from a tailored therapeutic strategy. The objectives of this project are: 1) To first describe lung microbiota dynamics during pneumonia, using longitudinal microbiome data from international cohorts; 2) To unveil a microbiota-based heterogeneity of pneumonia that is associated with clinical outcomes. This will lead to the development of a classification model to distinguish pneumonia patients based on their lung microbiome signature; 3) To assess the impact of a steroid-based therapy in hospital-acquired pneumonia, on lung microbiota, using data from an ongoing clinical trial and then validate the findings in vitro. Finally, I will investigate how prior microbiota-based classification of pneumonia patients can predict the clinical response to steroid therapy. The ambition of the MATRICS project is to propose a new insight in pneumonia pathophysiology that will deeply impact the therapeutic strategy towards a precision medicine. Such innovative approach could potentially extend to other respiratory diseases.
