Overview

The process of infection by bacteria or fungi can result in systemic signs and symptoms that are variously described. In rough order of severity, these are bacteremia or fungemia; septicemia; sepsis, severe sepsis or sepsis syndrome; septic shock; refractory septic shock; multiple organ dysfunction syndrome, and death. The condition develops as a response to certain microbial molecules which trigger the production and release of cellular mediators, such as tumor necrosis factors (TNF); these act to stimulate immune response.

Causes

Common Causes

Sepsis is caused by a bacterial infection that can begin anywhere in the body. Common places where an infection might start include:

• The bowel (usually seen with peritonitis)
• The kidneys (upper urinary tract infection or pyelonephritis)
• The lining of the brain (meningitis)
• The liver or the gall bladder (cholecystitis)
• The lungs (bacterial pneumonia)
• The skin (cellulitis)
• In children, sepsis may accompany infection of the bone (osteomyelitis).
• In hospitalized patients, common sites of infection include intravenous lines, surgical wounds, surgical drains, and sites of skin breakdown known as bedsores (decubitus ulcers).
