May 14, 2021 · With this review, we aim to provide an overview of sepsis immune pathophysiology, to update the choice of therapeutic approaches targeting different immunological mechanisms in the course of sepsis and septic shock, and to call for a paradigm shift from the pathogen to the host response as a potentially more promising angle.

Jan 18, 2024 · Sepsis results when the response to infection becomes generalized and involves normal tissues remote from the site of injury or infection. The pathophysiology of sepsis and mechanisms of multiple organ system dysfunction are reviewed here. The definition and management of sepsis are discussed separately.

What causes septic shock?
Epidemiology. An inability to strictly define and/or screen for sepsis has clearly influenced our understanding of sepsis epidemiology. Separate terminology and ICD-9 codes for bacteremia, “septicemia,” pneumonia, organ dysfunction, etc. have led to widely disparate estimates of the incidence and prevalence of sepsis throughout the world.

Jun 12, 2023 · This is described as cold shock. Understanding the pathophysiology and continuum of septic shock is imperative in initiating appropriate treatment measures. Functionally, septic shock is defined by persistent hypotension despite adequate fluid resuscitation from 60 ml/kg to 80 mL/kg of either crystalloid or colloid fluid.

Pathophysiology of Sepsis and Septic Shock. The pathogenesis of septic shock is not completely understood. An inflammatory stimulus (eg, a bacterial toxin) triggers production of pro-inflammatory mediators, including tumor necrosis factor (TNF) and interleukin (IL)-1.
The pathophysiology of sepsis is complex and results from the effects of circulating bacterial products, mediated by cytokine release, caused by sustained bacteraemia. Cytokines are primarily responsible for the clinically observable effects of the bacteraemia in the host.
Oct 4, 2021 · Septic shock is the most common form of distributive/vasodilatory shock related to release of vasoactive mediators such as prostacyclin and nitric oxide (NO). These mediators suppress autoregulation of blood flow and perfusion in central, regional, and microcirculatory beds and produce vasodilation and eventually hypotension.
