In septic patients, there is a combination of apoptotic and necrotic cell death. The term sepsis is frequently used to refer to septicemia (blood poisoning). %PDF-1.5 In its most severe form, sepsis causes multiple organ dysfunction that can produce a state of chronic critical illness characterized by severe immune dysfunction and catabolism. In septic shock, there is critical reduction in tissue perfusion; acute failure of multiple organs, including the lungs, kidneys, and liver, can occur.Common causes in immunocompetent patients include many different species of gram-positive and gram-negative bacteria. doi: 10.3205/id000053.
