Prenatal antibiotic exposure, asthma and the atopic march: A systematic review and meta-analysis

BackgroundAntibiotic use during pregnancy may increase the risk for asthma in children. We performed a meta-analysis assessing prenatal antibiotic exposure and the risk for childhood wheeze or asthma, as well as for diseases associated with the atopic march. MethodsA systematic literature search protocol (PROSPERO-ID: CRD42020191940) was registered and searches were completed using Medline, Proquest, Embase, …

Association of Diet and Antimicrobial Resistance in Healthy U.S. Adults

Antimicrobial resistance (AMR) represents a significant source of morbidity and mortality worldwide, with expectations that AMR-associated consequences will continue to worsen throughout the coming decades. Since resistance to antibiotics is encoded in the microbiome, interventions aimed at altering the taxonomic composition of the gut might allow us to prophylactically engineer microbiomes that harbor fewer antibiotic …

Evolution of the murine gut resistome following broad-spectrum antibiotic treatment

The emergence and spread of antimicrobial resistance (AMR) represent an ever-growing healthcare challenge worldwide. Nevertheless, the mechanisms and timescales shaping this resistome remain elusive. Using an antibiotic cocktail administered to a murine model along with a longitudinal sampling strategy, we identify the mechanisms by which gut commensals acquire antimicrobial resistance genes (ARGs) after a single …

(844.3) Gut commensal Coprococcus comes diminishes the blood pressure-lowering effect of ester angiotensin-converting enzyme inhibitors

Drug resistant HTN (rHTN) affects around 15% to 20% of hypertensive (HTN) patients. The underlying mechanisms of resistance to treatment remain poorly understood. The majority of angiotensin-converting enzyme inhibitors (ACEi) are esters, whereby we hypothesized that select gut microbiota hydrolyze ACEi rendering lower efficacy (Figure 1A). To test this hypothesis, we investigated if and which …

Association of midlife antibiotic use with subsequent cognitive function in women

The gut microbiome is increasingly recognized to play a role in cognition and dementia. Antibiotic use impacts the gut microbiome and has been linked with chronic disease. Despite these data, there is no evidence supporting an association between long-term antibiotic use in adults and cognitive function. We conducted a prospective population-based cohort study among 14,542 …
