Low 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...
متن کاملThe 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 کاملGender affects 13C-ketoisocaproic acid breath test.
BACKGROUND AND AIMS 13C-Ketoisocaproic Acid Breath Test (13C-Kica-BT) has been proposed to assess mitochondrial function. Aim of this study is to evaluate whether gender affects mithocondrial oxidation by means of 13C-Kica-BT in healthy subjects in basal conditions and after an acute oxidative stress induced by ethanol. METHODOLOGY 50 healthy volunteers were given 1 mg/kg of 13C-Kica together...
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 کاملGastric secretion does not affect the reliability of the 13C-acetate breath test: A validation of the 13C-acetate breath test by magnetic resonance imaging.
BACKGROUND (13)C-Acetate labeled meals are widely used to determine meal emptying by means of analyzing resulting (13)CO(2) exhalation dynamics. In contrast to the underlying metabolic processes, only few (13)C breath test meal emptying studies have focused on intragastric processes that may alter (13)CO(2) exhalation. This work assessed the effect of enhanced gastric secretion on the reliabili...
