How long-term heavy drinking changes sepsis outcomes
The Impact of Chronic Alcohol Abuse on the Pathophysiology of Sepsis
This project looks at how chronic heavy drinking alters the gut barrier and immune responses in people with alcohol use disorder who develop sepsis.

What this research studies
From a patient's point of view, researchers use a controlled model of long-term alcohol exposure followed by sepsis to see why outcomes are worse for people with alcohol use disorder. They focus on how the intestine becomes more leaky and how the adaptive immune system is disrupted after chronic alcohol use. The team studies specific gut barrier pathways and immune cells (including CD103-related responses) that may let gut contents trigger worse inflammation. The goal is to find biological mechanisms that could guide more targeted treatments for these patients.
Who could benefit from this research
Good fit: The findings are most relevant to adults with alcohol use disorder who develop or are at high risk for sepsis, especially those hospitalized with severe infection.
Not a fit: People without a history of chronic heavy alcohol use or those with non-sepsis illnesses are unlikely to benefit directly from the specific findings.
Why it matters
Potential benefit: If successful, this work could point to new, more personalized treatments that reduce death and complications from sepsis in people with alcohol use disorder.
How similar studies have performed: Prior animal and clinical studies have suggested links between alcohol, increased gut permeability, and worse infection outcomes, but targeted precision therapies for alcohol-related sepsis remain largely untested.
