The future of 13C-breath tests.
13C-breath tests are widely applied as a tool to investigate metabolic processes and infectious diseases, but most of them have not yet entered into clinical practice. In order to promote the introduction of more 13C-breath tests into clinical routine application we evaluated the tests so far known with respect to some reasonable criteria, which are valued by one of three marks. The sum sigma o...
متن کامل13C-breath tests in hepatology (cytosolic liver function).
13C-phenylalanine (PheBT) and 13C-galactose breath tests (GBT) explore non invasively the hepatic functional mass by measuring two enzymatic activities localized into the cytosol of liver cells: the phenylalanine hydroxylase (which converts phenylalanine into tyrosine) and the galactose kinase (which catalyzes the ATP-dependent phosphorylation of galactose to galactose 1-phosphate). Both BTs ar...
متن کامل13C-breath tests in the study of mitochondrial liver function.
Breath tests for "dynamic" liver function evaluation have been proposed several years ago. A variety of carbon-labelled breath tests for the assessment of mitochondrial, microsomal and cytosolic liver function have been described with the aim to increase data on liver disease staging, prognosis, and response to therapy. In the last years a great interest is developed about the use of breath tes...
متن کاملA Preliminary Study of 13C-Phenylalanine and 13C-Dipeptide Breath Tests in Horses
This study aimed to establish a standard dose and sample collection time for (13)C phenylalanine and (13)C-Dipeptide breath test in horses. To evaluate dose-dependent effects, healthy horses received 2.5 mg/kg, 5 mg/kg, and 10 mg/kg (13)C phenylalanine dissolved in 1 ml/kg distilled water and 1.25 mg/kg, 2.5 mg/kg, and 5 mg/kg (13)C dipeptide dissolved in 2 ml/ kg distilled water. Tmax was obse...
متن کاملLow dose capsule based 13c-urea breath test compared with the conventional 13c-urea breath test and invasive tests.
CONTEXT One of the limitations of 13C-urea breath test for Helicobacter pylori infection diagnosis in Brazil is the substrate acquisition in capsule presentation. OBJECTIVES The purpose of this study was to evaluate a capsule-based 13C-urea, manipulated by the Pharmacy Division, for the clinical practice. METHODS Fifty patients underwent the conventional and the capsule breath test. Samples...
