Procalcitonin as an early marker of bacterial infection
Mikulová, Lenka ; Beránek, Martin (advisor) ; Drastíková, Monika (referee)
Introduction: Procalcitonin (PCT) is a 13 kD protein with a chain of 116 amino acids. It consists of parafollicularcells of the thyroid gland. Inflammatory procalcitonin is made up of 114 amino acids. Procalcitonin from plasma in the course of inflammatory process, does not consistof C-cells of the thyroid gland but it is generatedin the liver, and, to a lesser extent, in the lungs, kidneys, testes, prostate and small intestine. Objectives: 1. To compare the levels and the dynamics of C-reactive protein (CRP) and procalcitonin in the inflammatory process. in three patients with different diagnoses. To compare the number of examined PCT according to indicated VFN (General University Hospital) departments in the years 2009, 2012 and 2015. 3. To study the dynamics of the number of examined PCT in the years 2001- 2016. Methods: The levels of CRP and PCT were measured in the ÚLBLD laboratory of the General University Hospital in Prague in the period from May 20to June 17, 2016. The CRP was measured by immunoturbidimetricanalyzerUnicelDxC 880i. The PCT was measured by theCobas analyser using the electrochemiluminescence technology. In order to evaluate the data, graphs were processed with levels of bothanalytesfor 3 patients. Further, data needed for the evaluation of the above mentioned objectives no. 2...

Significance of determination SAA of comparison with CRP and procalcitonin
Daňková, Michaela ; Zadina, Jiří (advisor) ; Průša, Richard (referee)
The purpose of the bachelor thesis is to evaluate serum amyloid (SAA) as a diagnostic marker in selected patient groups and to compare the results of SAA with those of C-reactive protein (CRP) and procalcitonin (PCT). SAA, CRP and PCT are acute-phase proteins, whose blood concentration significantly increases within a few hours after an inflammatory stimulus. The synthesis, caused by proinflammatory cytokines, takes place in the liver. CRP is the most and longest used acute-phase reactant in routine practice. As indicators of inflammation, SAA and especially procalcitonin have been used more lately. Although SAA is an acute-phase reactant as sensitive as CRP, it is not employed so often in the diagnosis since a method suitable for routine diagnosis was not developed until recently. Briefly describing the acute-phase proteins, the theoretical part elaborates on the characterization and comparison of SAA, CRP and PCT. It further outlines methods for the determination of individual analytes. The experimental part focuses on defining selected patient groups and the immunonephelometric method for measuring SAA by the Immage 800 biochemical analyzer. The data obtained in three selected patient groups have been statistically evaluated. The aim of the thesis has been to evaluate the correlation of inflammatory...

Procalcitonin in critically ill patients
Bureš, Martin ; Průcha, Miroslav (advisor) ; Zazula, Roman (referee)
The aim of this thesis was to determinate the levels of procalcitonin and Creactive protein in the serum of patients who met the criteria of sepsis diagnosis and the comparison with positive blood cultures that is the exact confirmation of infectious etiology of SIRS (Systemic Inflammatory Response Syndrome).

Laboratory markers of sepsis
OCHOZKOVÁ, Šárka
Sepsis and its complications are currently the most frequent cause of death owing to multi organ failure at intensive care units. The aim of this thesis was to evaluate the most suitable usable marker with sufficient diagnostic sensitivity and specificity for early catch of sepsis development. For my thesis a chosen data collection patients of intensive care units and patients of neonatology department in Nemocnice a.s. (Hospital Inc.) in České Budějovice was used. In patients, determinations of following concentration parameters were carried out: PCT, CRP, IL-6. For diagnosis and evaluation of clinical state change in relation to sepsis PCT is convenient. For monitoring of steady course and clinical state it is useful and sufficient to watch dynamics of CRP. In newborns the sensitivity PCT decreases in sepsis probably due to immaturity of liver and immunity system. That is why according to experience gained in Nemocnice a.s. (Hospital Inc.) České Budějovice it is more convenient to determine IL-6 instead of PCT.

Use of Procalcitonin Levels Measurement in Diagnosis and Prognosis of Septic States.
PAVLÍKOVÁ, Lenka
The Master thesis gives an overview of sepsis, its causes, manifestation and diagnostics. The role of procalcitonin as a sepsis marker is dicussed. In the experimental part, case records of 106 were examined and the determination of procalcitonin as a sepsis marker was evaluated. Based on the evaluation, a recommendation about timing of the procalcitonin level analyses with septic patients were made.
