Kvantifikace jaterních funkcí pomocí dechového testu s 13 C-methacetinem MUDr. Miluše HENDRICHOVÁ SUMMARY Efforts to evaluace and quantify liver functions has accompanied hepatology over the last 50 years at least. Quantification of liver function was hindered by multiple blood samploing, the low specificity of monitored parameters and the risk of allergic reactions when using conventional chromoexcretory tests. The introduction of breath tests using the non-radioactive isotope 13C allows non-invasive and highly accurate measurement of liver function. Especially 13C.methacetin is a very suitable substrate for evaluation demethylační and oxidative capacity of hepatocytes. Using the breath test with 13 C-methacetin is noninvasive, easy for patients and the results are reproducible. The aim of this thesis is to introduce the use of breath test with 13 C-methacetin into clinical practice as one of standard items in the care of patients with chronic liver diseases. In the first study we are evaluating liver function using breath test with 13 C-methacetin in patients with liver cirrhosis. The results show that the breath test reliably distinguishes patients with liver cirrhosis from patients without liver damage. Using ROC curves we demonstrate that the most advantageous time of the breath test that best predicts...
