Repeatability and effect of blinding of fructose breath tests in patients with functional gastrointestinal disorders.
Wilder-Smith CH, et al. Neurogastroenterol Motil 2019 - Clinical Trial. PMID 30393978
METHODS: Gastrointestinal symptoms and breath concentrations of hydrogen and methane were documented during breath tests with fructose (given open twice and blinded once), water (blind neutral nocebo) and a cyclamate/saccharine sweetener (blind sweet nocebo) on 5 days in patients with FGID. ...CONCLUSIONS & INFERENCES: Fructose breath tests showed moderate repeatability for intolerance status and for AUCs of symptoms and gas concentrations, lying within the range of accepted gastrointestinal sensory and transit tests. ...

Methods and functions: Breath tests.
Braden B. Best Pract Res Clin Gastroenterol 2009 - Review. PMID 19505663
Breath tests provide a valuable non-invasive diagnostic strategy to in vivo assess a variety of enzyme activities, organ functions or transport processes. Both the hydrogen breath tests and the (13)C-breath tests using the stable isotope (13)C as tracer are non-radioactive and safe, also in children and pregnancy. ...

Breath Hydrogen Testing in East and Southeast Asia.
Yao CK, et al. J Clin Gastroenterol 2018 - Review. PMID 29035975
Breath hydrogen tests are popular, noninvasive tests for the assessment of carbohydrate fermentation in patients with irritable bowel syndrome (IBS) and functional dyspepsia (FD). There is limited information regarding the utility of breath hydrogen and methane tests in IBS and FD patients in East and Southeast Asia. ...

Diagnostic accuracy of breath tests for pneumoconiosis using an electronic nose.
Yang HY, et al. J Breath Res 2017. PMID 28795953
Breath analyses have attracted substantial attention as screens for occupational environmental lung disease. The objective of this study was to develop breath tests for pneumoconiosis by analysing volatile organic compounds using an electronic nose. ...Breath tests may have potential as a screen for pneumoconiosis. A multi-centre study is warranted, and the procedures must be standardized before clinical application....

Stable isotope biomarker breath tests for human metabolic and infectious diseases: a review of recent patent literature.
Timmins GS. Expert Opin Ther Pat 2016 - Review. PMID 27467014 Free PMC article.
Stable isotope breath tests can rapidly and quantitatively report metabolic phenotypes and disease in both humans and microbes in situ. ...Areas covered: This review details the unique advantages (and disadvantages) of phenotypic stable isotope based breath tests. ...

Quality control for multiple breath washout tests in multicentre bronchiectasis studies: Experiences from the BRONCH-UK clinimetrics study.
O'Neill K, et al. Respir Med 2018. PMID 30509710
INTRODUCTION: Multiple Breath Washout (MBW) to measure Lung Clearance Index (LCI) is increasingly being used as a secondary endpoint in multicentre bronchiectasis studies. ...METHODS: Data were analysed from 250 MBW tests (from 98 adult bronchiectasis patients) collected as part of the Bronch-UK Clinimetrics study in 5 UK centres. ...

Targeted breath analysis: exogenous volatile organic compounds (EVOC) as metabolic pathway-specific probes.
Gaude E, et al. J Breath Res 2019. PMID 30965287
After five decades, a very limited number of breath tests measuring endogenous VOCs is applied to the clinic. In this perspective article, we explore some of the factors that may have contributed to the current lack of clinical applications of breath endogenous VOCs. ...EVOC strategies could herald a new wave of substrate-based breath tests, potentially bridging the gap between research tools and clinical applications....

Non-contact breath sampling for sensor-based breath analysis.
Mochalski P, et al. J Breath Res 2019. PMID 30818286
However, miniaturized breath analyzers require adequate breath sampling methods. In this context, we propose non-contact sampling; namely the collection of breath samples by exhalation from a distance into a miniaturized collector without bringing the mouth into direct contact with the analyzing device. ...In conclusion, non-contact breath sampling can be considered as a promising alternative to the existing breath sampling methods, being relatively close to natural spontaneous breathing....

13C breath tests: visions and realities.
Klein PD. J Nutr 2001 - Review. PMID 11340131
Breath tests have been used in research laboratories for over 25 y. Originally, the tests were based on the use of (14)C, rather than on the nonradioactive isotope, (13)C. ...Thus far, the only test to be approved by the Food and Drug Administration is the (13)C-urea breath test. This manuscript describes the process by which approval is gained, and indicates the steps necessary for other tests to receive Food and Drug Administration approval....

[Modern breath analysis].
Wirtz LM, et al. Med Klin Intensivmed Notfmed 2019 - Review. PMID 30725273 German.
Modern breath analysis can detect very low concentrations of volatile components. Current research focuses on drug monitoring and diagnosis of various diseases. OBJECTIVES: Presentation and discussion of current breath research relevant to intensive care medicine. MATERIALS AND METHODS: The literature in PubMed was searched using the following terms: "breath analysis", "volatile organic compounds", "critically ill" combined with "drug monitoring", "propofol", "heart failure", "pneumonia", "ARDS", "renal failure", "liver failure", "sepsis" or "hemorrhage". ...
