ABSTRACT
Helicobacter pylori infection was investigated by two different methods, microscopically and biochemically in 200 dyespeptic patients [149 male and 51 female] aged from 40-70 years. All patients divided into two groups, the first one as control group [100] and without liver cell failure, the second studied group [100] as diseased group with liver cell failure. Helicobacter pylori infection was diagnosed in 54% in the first group and 78% in the second group. The Helicobacter pylori prevalence in the second group of liver cell failure was significantly higher than in the first control group and was not correlate to the sex difference, etiology of the liver cell failure, child classification or any endoscopic finding of gastroduodenal mucosal lesion. In both groups Helicobacter pylori infection was significantly higher in patients over 40
