Abstract
Muscular loss is a characteristic phenomenon induced by a massive inflammation as occurring in sepsis. Indeed, the early phase of sepsis is responsible for the expression of proinflammatory cytokines, namely TNFα and IL-6, known to be effectors of cachexia. Although cachexia is a morbidity factor in human, there is to date no animal model of septic cachexia. The goal of this study is to create and characterize a murine model of septic cachexia and evaluate endogenous ghrelin variations. Among the factors involved in both sepsis and muscular protection, current research highlights a potential role for ghrelin in muscle protection but there are conflicting data regarding its variations during experimental sepsis. In this study we evaluate its two circulating forms (AG, acylated ghrelin and UAG, unacylated ghrelin).
Highlights
During the course of systemic inflammation, most of the immune cell types get activated to a certain degree as part of, or contributing to, the cascade of physiopathological events
After the development of sepsis we detected in all patients significantly increased heart rate, respiratory rate per minute, leukocytosis, anemia, worse glucose metabolism and renal function (Table 1)
Free KDO in the used concentration was inactive in regulation of TLR4, CD11b and CD14 expression and did not induce tumor necrosis factor alpha (TNFa) release but its impact in biological activity was detected when KDO was applied as constituent of Re-LPS
Summary
During the course of systemic inflammation, most of the immune cell types get activated to a certain degree as part of, or contributing to, the cascade of physiopathological events. This study aimed to find out whether mean differences of 6-hour, 12-hour, and 24-hour lactate clearance were observed between nonsurvivors and survivors of acute phase mortality in severe sepsis and septic shock patients. Conclusion: A two-phase retrospective chart review study demonstrated that the SSST utilized at a community hospital in Miami had a sensitivity value of 41.49% and a specificity value of 90.53% when evaluating medical surgical patients These results indicate the tool is accurate in detecting patients that are not septic; it is not reliable in identifying patients who are truly septic. This study was aimed to address the association of achieving either one or two targets of microcirculatory end point resuscitation and early mortality in severe sepsis and septic shock patients. Conclusion: Achieving both lactate clearance and ScvO2 targets in 6 hours after onset of resuscitation associates with lowest early mortality risk in severe sepsis and septic shock patients. Other blood samples were collected in blood culture tubes for culturing to verify septicemia depending on the clinical evidence
