Many Livers Too Fat for Transplant

Dr. Kenneth Andreoni, a UNOS committee member, said the increasing prevalence of comorbidities in donors is a "double-edged sword" because it reflects the fact that public health messages about safety are getting through to younger people, even though that may mean fewer quality donors.

"We're seeing fewer young people dying in traumas, but we're getting less high-quality, excellent organs," Andreoni told MedPage Today. "The question is, how can we make the best use of more middle-age and older donors?"

When it comes to organs with fatty liver disease, some researchers have been trying to better quantify the type of fat in the liver so that surgeons can have a better idea of what's usable and what's not, said Andreoni, who is from Ohio State University in Columbus.

Improvements on the pathology side may also be needed, he said. For instance, pathologists may need to offer a more specific range in terms of the percentage of fat in the organ, so clinicians can more easily recognize if an organ needs to be discarded or not.

Other work has focused on whether there are better ways to protect a fatty liver so it has a better chance of working after it's transplanted. "Is there something you can put in during reperfusion, like an antioxidant, that will lead to better outcomes?" Andreoni said.
