Study: Free fatty acid may be able to fight catheter-related bloodstream infections

A free fatty acid, made up of compounds similar to those naturally made in the body, may be as effective at fighting catheter-related bloodstream infections as antibiotics, according to a study published in the Journal of Antimicrobial Chemotherapy.

Researchers studied the use of specific antimicrobial lock solutions for the treatment of catheter-related bloodstream infections. The prototype used in this study — ML9-X10 — is a novel, free fatty acid catheter lock solution that is under development.

The study found that, in laboratory experiments, the treatments were equally, if not more, effective than antibiotics in treating catheter infections.

“More and more bacteria are developing resistance to commonly used antibiotics,” said Leonard Mermel, DO, medical director of the department of epidemiology and infection control at Rhode Island Hospital in Providence and a study author. “This study shows that in some cases, we may have an alternative to antibiotics in preventing and treating infections caused by intravenous catheters.”
