[Influence of exogenous factors on the behavior of aminophenazone breath test in chronic liver diseases].

230 patients with different chronic liver diseases of various severity were researched because of the influence of nicotine and alcohol on the results of the aminopyrine breath test in the modification of Haustein and Schenker (1985). Smoker with chronic liver diseases had higher 14CO2-results than nonsmoker. The difference was only significant in fatty liver disease in the first stadium (p less than 0,001) and chronic active hepatitis (p less than 0.05). Patients with chronic liver diseases of fewer severity had higher mean values of aminopyrine breath test, if they had chronic alcohol consumption. The difference between these and abstinent patients could secure only in fatty liver disease in the first stadium (p less than 0.001). Patients with severe chronic liver diseases had lower results of aminopyrine breath test, if they drink alcohol regular. These difference was significant in patients with cirrhotic liver disease (p less than 0.05).
