Bacterial sepsis

Bacterial sepsis is a life-threatening clinical syndrome defined by acute, life-threatening organ dysfunction caused by a dysregulated systemic host immune response to a bacterial infection

Although it can develop in any individual, it most frequently arises from bacterial primary sources in the respiratory tract, urinary system, abdomen, or bloodstream, disproportionately affecting vulnerable populations such as older adults, infants, and immunocompromised patients

Pathophysiologically, the condition is driven by widespread pro- and anti-inflammatory signaling cascades, microvascular leak, and coagulation abnormalities, culminating in impaired tissue perfusion, cellular hypoxia, and potential progression to multiple organ failure or septic shock
