ACCP 2023 Clinical Practice Webinar - Leveraging Novel Microbiome-related Therapies | ON DEMAND

On Demand webinar recording:  May 24, 2023 to May 24, 2026

Why is this article important to your practice? 

This clinical webinar will introduce the gut-brain axis including an overall perspective with relevant publications. The presentation will also discuss the link between the gut-brain, alcohol and other addiction (eating) disorders including examples of gut-brain-related neuroendocrine pathways (e.g., ghrelin, GLP-1) that may be relevant in the development of neuro-behavioral conditions such as addiction. Preliminary rat results will be presented from observations of binge-like alcohol drinking leading to changes in the gut microbiome in a manner independent from the presence or not (knock-out) of the ghrelin receptor. Additionally, results from a recently-published manuscript investigating the gut microbiome and metabolome of binge-drinking primates will be reviewed. Speakers will introduce an unpublished clinical protocol and will present preliminary gut microbiome data investigating the gut microbiome of abstinent and currently drinking individuals with alcohol use disorder (AUD) and controls.

Target Audience: 

Physicians, Pharmacists, PhDs and healthcare professionals interested in clinical pharmacology.

Learning Objectives: 

After completing this activity, the learner will be able to:

1. Identify the broad characterization of pathology associated with microbiome changes in several neurological conditions;

2. Estimate the correlations of microbial changes in neuro-behavioral statuses like eating disorders and AUD;

3. Assess why periodontitis is more common in AUD and compare the abundances of health- and periodontitis-associated previously identified genera to those in individuals with AUD;

4. Explore the influence of alcohol consumption and type of drinking and observe longitudinal-temporal changes in the oral microbiome in newly abstinent individuals undergoing inpatient treatment for AUD.

He is also an Adjunct Professor of Addiction Medicine at Johns Hopkins University and of Neuroscience at Georgetown University. Dr. Leggio, together with his team, colleagues and collaborators have pioneered and conducted work on medication development, on the role of the microbiome-gut-liver-brain axis and on the role of neuroendocrine pathways in addictive behaviors via human laboratory studies and clinical trials as well as via translational and reverse translational experimental medicine approaches.
