Klinisch relevante Atemtests in der gastroenterologischen Diagnostik - Empfehlungen der Deutschen Gesellschaft für Neurogastroenterologie und Motilität sowie der Deutschen Gesellschaft für Verdauungs- und Stoffwechselerkrankungen

Abstract: H (2)- and (13)C-breath tests are valuable non-invasive diagnostic tools for gastroenterological diseases. H (2)-breath tests are clinically established for the diagnosis of carbohydrate intolerance resulting from malabsorption (H (2)-breath tests with lactose, fructose, saccharose, sorbitol), of bacterial overgrowth (glucose H (2)-breath test) and for measurement of orcoceal transit time (lactulose H (2)-breath test). The (13)C-urea breath test is regarded as the "gold standard" procedure for the diagnosis of… Show more

“…Following a minimum of three trials, breath samples (50 ml) were taken after the initial 200-300 ml of exhaled air (from extrapulmonary airways) had been discarded. Breath samples were collected before and every 30 min during the following 3 h after ingestion of the substrate.Breath samples were analyzed for hydrogen concentration in parts per million with an electrochemical analyzer (Stimotron Medical, Wendelstein, Germany).Breath test results were assessed according to the recommendations of the German Society of Digestive and Metabolic Diseases (DGVS) and the German Society of Neurogastroenterology and Motility[23]. Small intestinal bacterial overgrowth was diagnosed if the increase of the breath hydrogen content exceeded 20 ppm compared with baseline values or if the pretest values already topped 20 ppm.Demographic baseline data have been expressed as medians and ranges, if not otherwise specified.…”

“…Die Tests mit 13 C-Stärke oder 13 C-markierten Proteinen zeigen aber eine unzureichende Sensitivität und Spezifität im Vergleich zu etablierten Pankreasfunktionstests ( 13 C-Stärke) oder befinden sich noch im experimentellen Stadium ( 13 C-markierte Proteine; [9]). Triglyzeride können vom menschlichen Dünndarm erst resorbiert werden, nachdem sie durch die Pankreaslipase zu 2-Monoacylglycerol und freien Fettsäuren hydrolysiert wurden.…”

“…Dies erlaubt eine kürzere Testdauer. Zudem wird 13 C-Oktansäure weniger stark in das kör-pereigene Fettgewebe eingebaut, was sich in einer höheren maximalen und kumulativen Abatmungsrate zeigt und die Diskrimination zwischen normalen und pathologischen Ergebnissen erleichtert [9]. Das Testprinzip kann .…”

“…Dies gewährleis-tet die Koordination der glatten Muskelzellen untereinander, mit den sekretorischen und absorptiven Funktionen des Gastrointestinaltrakts sowie den überge-ordneten, allgemeinen Bedürfnissen des Organismus. [4]. Für den Test wird eine Dosis von 10 g in 200 ml Wasser gelöster Laktulose empfohlen; die Gewinnung von Atemproben erfolgt in 15-minütlichen Intervallen über 3 h oder bis zu einem signifikanten H 2 -Anstieg in der Atemluft (>20 ppm).…”
