Aspergillus fumigatus produces 2-pentylfuran (2-PF) when cultured on blood agar, nutrient agar and other media. As 2-PF is not known to be produced by mammalian metabolism we hypothesized that it is detectable in breath of patients colonized or infected with A. fumigatus. Breath was tested for 2-PF from normal subjects, those undergoing chemotherapy, and adults at risk of colonization or infect...
Objective: The present study was conducted to evaluate invasive and noninvasive diagnostic methods for detection of Helicobacter pylori (H. pylori) in patients admitted with dyspeptic complaints and to compare sensitivities and specificities. Method: Sets of four gastric biopsy specimens were obtained from a total of 126 patients included in the study. The presence of H. pylori was determined b...
Background—Current breath tests for measurement of gastric emptying of solids are expensive, possibly inaccurate, and require cumbersome calculations. Aims—We wished to validate a simplified solid gastric emptying test using a [C]Spirulina platensis breath test for accurate results relative to scintigraphy. Subjects—Thirty healthy volunteers. Methods—We measured gastric emptying of egg containi...
BACKGROUND Helicobacter pylori (H. pylori) is one of the most common bacterial infections in humans. There is a risk factor for gastric or duodenal ulcers, gastric cancer and MALT (Mucosa Associated Lymphoid Tissue)-Lymphomas. There are several invasive and non-invasive methods available for the diagnosis of H. pylori. The (13)C-urea breath test is a non-invasive method recommended for monitori...
