Title: Nicotinamide Phosphoribosyltransferase in Sepsis
Abstract: The word sepsis was derived from the Greek word: sepsis, which means the state of putrefaction or decay. Sepsis is a potentially deadly medical condition that is characterized by a whole-body inflammatory state, called a systemic inflammatory response syndrome, and the presence of a known or suspected infection. The more critical subsets of sepsis are severe sepsis with acute organ dysfunction, hypoperfusion, or hypotension and septic shock with refractory arterial hypotension despite adequate fluid resuscitation [1, 2]. Because the molecular pathogenesis of sepsis is incompletely understood and its specific and effective therapies are lacking, sepsis is still a major cause of death in intensive-care units worldwide, with mortality rates that range from 20% for sepsis, through 40% for severe sepsis, to over 60% for septic shock [3, 4]. More knowledge of the pathophysiology of sepsis is needed if we are to develop better, more effective interventions to sepsis. It has been increasingly recognized that genetic factors influence individual susceptibility, severity and outcome in sepsis [5, 6]. Identification of new genetic factors in sepsis may hold promise for new mechanistic insights and new therapeutic modalities.
