Sepsis (in Greek Σήψις, putrefaction) is a serious medical condition caused by a severe Infection leading to a systemic inflammatory response. The more critical subsets of sepsis include severe sepsis (sepsis with acute organ dysfunction) and Septic shock (sepsis with refractory arterial Hypotension).

Septicemia is sepsis of the bloodstream caused by Bacteremia, which is the presence of bacteria in the bloodstream. The term septicemia is also used to refer to sepsis in general.

Symptoms

The systemic inflammatory response syndrome leads to widespread activation of Inflammation and Coagulation pathways. This may progress to dysfunction of the Circulatory system and, even under optimal treatment, Multiple organ dysfunction syndrome and eventually Death.

Sepsis is more common and also more dangerous in elderly, immunocompromised, and critically ill patients. It occurs in 2% of all hospitalizations and accounts for as much as 25% of intensive care unit (ICU) bed utilization. It is a major cause of death in intensive care units worldwide, with mortality rates that range from 20% for sepsis to 40% for severe sepsis to >60% for Septic shock. In the United States, sepsis is the leading cause of death in non-coronary ICU patients, and the tenth most common cause of death overall according to 2000 data from the Centers for Disease Control and Prevention (Martin, et al., 2003).

A problem in the adequate management of septic patients has been the delay in administering the right treatment after sepsis has been recognized. A large international collaboration was established to educate people about sepsis and to improve patient outcomes with sepsis, entitled the "Surviving Sepsis Campaign." The Campaign has published an evidence-based review of management strategies for severe sepsis (Dellinger, et al., 2004), with the aim to publish a complete set of guidelines within 3 years.

Treatment

The therapy of sepsis rests on antibiotics, surgical drainage of infected fluid collections, fluid replacement and appropriate support for organ dysfunction. This may include hemodialysis in Kidney failure, Mechanical ventilation in pulmonary dysfunction, transfusion of Blood plasma, platelets and coagulation factors to stabilize blood Coagulation, and drug and fluid therapy for circulatory failure. Ensuring adequate nutrition, if necessary by parenteral nutrition, is important during prolonged illness.

Most therapies aimed at the inflammatory process itself have failed to improve outcome. However, drotrecogin (activated Protein C, one of the coagulation factors) has been shown to decrease mortality from about 31% to about 25% in severe sepsis (Bernard, et al., 2001). Low dose Cortisol treatment has shown promise for Septic shock patients with relative Adrenal insufficiency.
