RT Journal A1 Chang HJ, Lynm C, Glass RM T1 SEpsis JF JAMA JO JAMA YR 2010 FD February 24 VO 303 IS 8 SP 804 OP 804 DO 10.1001/jama.303.8.804 UL http://dx.doi.org/10.1001/jama.303.8.804 AB Sepsis is a medical condition in which the immune system goes into overdrive, releasing chemicals into the blood to combat infection (microbes in the blood, urine, lungs, skin, or other tissues) that trigger widespread inflammation (cellular injury in body tissues). If the body is not able to regulate this immune response, it then overwhelms normal blood processes. The first mention of the word sepsis in a medical context was more than 2700 years ago in the poems of Homer. The word derives from the Greek word sepein, meaning "to rot." Sepsis occurs in 1% to 2% of all hospitalizations in the United States, affecting at least 750 000 persons and costing $17 billion per year to treat. A term sometimes used for sepsis is "blood poisoning," but there is no poison involved in sepsis. The February 24, 2010, issue of JAMA includes an article about possible treatments for early sepsis.
