433. Impact of Antibiotics on the Gut Microbiota: Comparisons Using Model-Based Analyses

Carlos Olivares, Jean de Gunzburg, Étienne Ruppé, Antoine Andremont et autres

Abstract Background Antibiotic (AB) treatments shift the gut microbiota composition according to their spectrum of activity, posology and intestinal excretion rate. We compared the impact of various ABs on gut microbiota bacterial diversity. Methods We used data from 2 RCTs, DAV-132-CL1004 and …

A modelling framework to characterize the impact of antibiotics on the gut microbiota diversity

Carlos Olivares, Étienne Ruppé, Stéphanie Ferreira, Tanguy Corbel et autres

Metagenomic sequencing deepened our knowledge about the role of the intestinal microbiota in human health, and several studies with various methodologies explored its dynamics during antibiotic treatments. We compared the impact of four widely used antibiotics on the gut bacterial diversity. We …

Shotgun metagenomics and systemic targeted metabolomics highlight indole-3-propionic acid as a protective gut microbial metabolite against influenza infection

Séverine Heumel, Vinícius de Rezende Rodovalho, Charlotte Urien, Florian Specque et autres

The gut-to-lung axis is critical during respiratory infections, including influenza A virus (IAV) infection. In the present study, we used high-resolution shotgun metagenomics and targeted metabolomic analysis to characterize influenza-associated changes in the composition and metabolism of the mouse gut microbiota. We …

Abstract 5882: Prevention of antibiotic-induced dysbiosis in human volunteers by DAV132 and preservation of responsiveness to anti-PD-1 demonstrated by transplantation of human feces into tumor-bearing mice

Meriem Messaoudene, Nathalie Saint-Lu, Frédérique Sablier-Gallis, Stéphanie Ferreira et autres

Abstract Background: Over the last decade, studies unraveled the cancer-immune dialogue in the setting of immune checkpoint inhibitors (ICI) and influenced by the gut microbiota. The first evidence of the key role of the microbiota in ICI modulation was observed during antibiotics …

Characterisation of gut microbiota composition in patients with axial spondyloarthritis and its modulation by TNF inhibitor treatment

Marie Vallier, Béatrice Segurens, Élise Larsonneur, Vincent Meyer et autres

Objective To assess whether gut microbiota composition is associated with patient characteristics and may have predictive value on the response to TNF inhibitor (TNFi) treatment in axial spondyloarthritis (AxSpA). Methods The study involved 61 patients fulfilling the Assessment of SpondyloArthritis International Society …

Meriem Messaoudene, Nathalie Saint-Lu, Frédérique Sablier-Gallis, Stéphanie Ferreira et autres

Background Antibiotics (ATB) induce intestinal dysbiosis and decrease the efficacy of immune checkpoint inhibitors (ICI).1,2 DAV132 is an orally administered colon-targeted ATB adsorbent designed to prevent ATB-induced dysbiosis.3 We investigated whether DAV132 co-administered with ATB could protect gut microbiota diversity and composition. …
