Sepsis is not a single syndrome but multiple distinct conditions much like cancer, suggest researchers.
Sepsis is a life-threatening condition when the body's response to an infection damages its own tissues and organs. The disease accounts for over 6 million global deaths annually.
A new study, by a team of researchers from University of Pittsburgh in the US, stresses the need of testing more therapies for the treatment of different types of sepsis.
"But these protocols ignore that all sepsis patients are not the same. For a condition that kills over 6 million people annually, that's unacceptable. Hopefully, by seeing sepsis as several distinct conditions with varying clinical characteristics, we can discover and test therapies precisely tailored to the type of sepsis each patient has," Seymour remarked.
For the study, published in Journal of the American Medical Association, researchers used computer algorithms to analyse 29 clinical variables found in the electronic health records of over 20,000 patients.
They noted that the algorithm clustered the patients into four different sepsis types, described as -
"Intuitively, this makes sense - you wouldn't give all breast cancer patients the same treatment. Some breast cancers are more invasive and must be treated aggressively," said senior author Derek Angus, Professor at the University.
"The next step is to do the same for sepsis that we have for cancer - find therapies that apply to the specific types of sepsis and then design new clinical trials to test them," Angus said.
