Sepsis, septic shock and multiple organ dysfunction syndrome: selected cellular immune mechanisms and methodological aspects
Karvunidis, Thomas ; Matějovič, Martin (advisor) ; Firment, Jozef (referee) ; Průcha, Miroslav (referee)
SEPSIS, SEPTIC SHOCK AND MULTIPLE ORGAN DYSFUNCTION SYNDROME: SELECTED CELLULAR IMMUNE MECHANISMS AND METHODOLOGICAL ASPECTS MUDr. Thomas Karvunidis ABSTRACT Sepsis and septic shock with multiple organ dysfunction syndrome are frequent life-threatening conditions. Despite long-time scientific effort, their exact pathophysiology, causal treatment, and prevention remain obscure. The numbers of mediators and elements (e.g. leukocytes, thrombocytes, endothelium/microcirculation etc.) have been suggested as key mediators in the process of initiation and modulation of this dreadful disease. The aim of the thesis is to better describe and document the cellular mechanisms in the pathophysiology of sepsis, septic shock and multiple organ dysfunction syndrome using different analytic methods including microcirculation assessment, flowcytometry, and proteomics. The first original manuscript studied the role of neutrophils in the process of microcirculation impairment in septic shock patients, as a central pathophysiological mechanism of systemic inflammation. The real-time intravital videomicroscopy technique was used. This is the first clinical study reporting microvascular changes in septic shock patients with chemotherapy-induced cytopenia. The microcirculation injury was identical in cytopenic compared to...
