cascade of host inflammatory response in sepsis

2015. in plasma. Any infection can result in sepsis, and multiple organisms, bacterial, fungal and viral, can initiate a septic response. Sepsis is considered the final common pathway by which the vast majority of patients with severe infection die. [free full text] Chertoff J, Chisum M, Garcia B, Lascano J. Lactate kinetics in sepsis and septic shock: a review of the literature and rationale for further research. Weakened Inflammation Control Mechanisms. The pleiotropic effects of LPS are largely indirect, and are orchestrated via its ability to trigger the release of an array of host-derived mediators of inflammation. Further dissection of the role of host–pathogen interactions, the cytokine response, the coagulation cascade, and their multidirectional interactions in sepsis should lead toward the development of new therapeutic strategies in sepsis. Bosmann M, Ward PA. Sepsis being formally defined as “life-threatening organ dysfunction caused by a dysregulated host response to infection” . Sepsis is a clinical syndrome caused by a deregulated host response to an infection. 2013. Trends in immunology. Localized tissue response to infection becomes systemic and the inflammatory process becomes deleterious in its own right. The specific agents can be divided into those designed to interrupt the initial cytokine cascade ... in the inflammatory host response. The signs and symptoms of sepsis and septic shock are nonspecific but may include fever, tachycardia, hypotension, and an elevated lactate. Sepsis as a dysfunctional inflammatory state It has been known for some time that sepsis in human beings or animals exhibits evidence suggesting that regulation of the inflam-matory response has been lost, resulting in high levels of pro-inflammatory mediators (IL-1 , tumour necrosis factor [TNF]- , IL-6, IL-8, etc.) Pittet D, Rangel-Fausto MS, Li N. Systemic inflammatory response syndrome, sepsis, severe sepsis and septic shock: incidence, morbidities and outcomes in surgical ICU patients. Like any inflammation, it starts with the local mobilization of macrophages and neutrophils and the activation of the complement and coagulation systems. 65. Physiologically, inflammation-dependent activation of the coagulation system is part of the host response to pathogens, aiming to limit their systemic spread in the bloodstream. An array of pro-inflammatory cytokines is produced, and there is local edema. Journal of intensive care. Sepsis begins as the typical inflammatory response to an infection. Sequence of events: Sepsis can be simply defined as a spectrum of clinical conditions caused by the immune response of a patient to infection that is characterized by systemic inflammation and coagulation. [free full text] Int Care Med . Effects are seen across organ and tissue types. Host innate immune responses to sepsis the host, so-called danger-associated molecular patterns. 34(3):129-36. Sepsis occurs when the host’s immune response becomes generalized, causing imbalances in the coagulation cascade, endothelial injury, tissue ischemia, cellular injury, and apoptosis. Coagulation activation in sepsis and potential drug targets for treatment of sepsis. In fact, the host response to infection (or injurious stimuli) may be a more critical determinant of the outcome of sepsis and ARDS than the original inciting stimulus. 3:39.
