  • gc ms analysis of breath odor compounds in liver patients
    Journal of Chromatography B, 2008
    Co-Authors: Sandra Van Den Velde, Frederik Nevens, Paul Van Hee, Daniel Van Steenberghe, Marc Quirynen
    Abstract:

    Abstract Background Liver diseases can cause a sweet, musty aroma of the breath, called Fetor Hepaticus. Even in a stage of cirrhosis, the disease can be asymptomatic for many years. Breath analysis might be helpful to detect occult liver pathology. Study objective This study examined whether specific breath odor compounds can be found in liver patients, suffering from cirrhosis, which might be useful for diagnosis. Materials and methods Fifty-two liver patients and 50 healthy volunteers were enrolled. Alveolar air was analyzed by gas chromatography–mass spectrometry. Using discriminant analysis a model for liver disease was built. Results Dimethyl sulfide, acetone, 2-butanone and 2-pentanone were increased in breath of liver patients, while indole and dimethyl selenide were decreased. Sensitivity and specificity of the model were respectively 100% and 70%. Conclusions Fetor Hepaticus is caused by dimethyl sulfide and to a lower extent by ketones in alveolar air. Breath analysis by GC–MS makes it possible to discriminate patients with breath malodor related to hepatic pathologies.
