Popis: BACKGROUND: In patients with hereditary bleeding disorders, upper gastrointestinal bleeding presents a life-threatening complication, while the role of Helicobacter pylori (H. pylori) infection in this group of patients has not been fully clarified in the literature. The aim of the present study was to evaluate the role of H. pylori infection and of dental status in upper gastrointestinal bleeding in patients with hereditary hemorrhagic disorders (HHD). METHODS: Thirty-seven patients with HHD (18 patients with and 19 without a history of upper gastrointestinal bleeding) and 26 control patients without HHD, who were admitted to our hospital for elective gastroscopy due to dyspeptic symptoms, were included in the study. Endoscopy was performed on all patients with gastrointestinal bleeding and on controls. ELISA was used to detect IgG, anti-CagA, and IgA antibodies to H. pylori in the serum and saliva of patients and controls. Moreover, dental status was examined using the decayed/missing/filled teeth index (DMFT) in all subjects. The chi(2)-test was used for statistical analysis. RESULTS: Some 64.8% of the patients and 65.4% of the controls had H. pylori IgG antibodies in serum (P>0.1, NS) while 54.05% of the patients and 34.6% of controls were anti-CagA-positive in serum (P=NS). However, 83 and 26.3% of the HHD patients with and without gastrointestinal bleeding, respectively, were serum anti-CagA-positive (P
