An antidepressant drug used to treat obsessive-compulsive disorder could save people from deadly sepsis, new research from the University of Virginia School of Medicine suggests.

Sepsis is a significant cause of death around the world. The federal Centers for Disease Control and Infection calls it "the body's extreme response to an infection." Essentially, the body's immune response spirals out of control, and the normally beneficial inflammation becomes harmful. The result can be tissue damage, organ failure or even death.

Gaultier and his team have identified a drug that could offer that treatment - and previous safety testing of the drug could fast-track it into use in hospitals around the country.

The UVA researchers were looking at a little-studied biological process inside our cells when they determined it has an important role in regulating inflammation. They began studying it partly because there are already drugs that can affect players in the process.

"Inflammation, most of the time, is good. It's when it gets out of control that we need to modulate it," Gaultier said. "Inflammation is a very precisely controlled reaction. When we need it and have too much, it's a problem, but when we don't have enough, it's also a problem."

To evaluate the potential of one drug, the antidepressant fluvoxamine, to stop sepsis, Gaultier's team tested it in a mouse model of the disease. The drug worked very effectively, they found.

While the drug will need to be tested in people to determine its effectiveness at battling human sepsis, previous testing to determine its safety should accelerate that process.
