Why obesity may protect people during sepsis

Obesity-mediated protection in sepsis

NIH-funded research University of Kentucky · NIH-11332827

Researchers are comparing immune responses and cell metabolism in obese and non-obese patients with sepsis to understand why obesity appears linked to better survival.

What this research studies

If you have sepsis, the team wants to see how having obesity changes your immune system and how your cells use energy. They will compare blood and tissue samples from people with and without obesity and also use a validated mouse model to study underlying biology. The researchers will focus on immune cell function and metabolic shifts that might explain the protective effect. That information could point to new treatments that mimic the protective factors for all patients with sepsis.

Who could benefit from this research

Good fit: Adults hospitalized with sepsis, both with and without obesity, who can provide blood or tissue samples would be appropriate candidates.

Not a fit: People who do not have sepsis, pediatric patients if the work is limited to adults, or those unable or unwilling to provide samples may not be eligible or directly benefit.

Why it matters

Potential benefit: If successful, this work could lead to new treatments that lower deaths and complications from sepsis by copying protective mechanisms seen in obesity.

How similar studies have performed: Clinical observations have repeatedly noted an 'obesity paradox' with better sepsis survival, but mechanistic studies are limited and this combined human-and-mouse approach is relatively novel.
