Effect of helicobacter pylori infection on hyperdynamic circulatory state and portal hypertensive gastrropathy in liver cirrhotic patients / 中国免疫学杂志

ABSTRACT

Objective:To evaluate the effect of Helicobacter pylori infection on hyperdynamic circulatory state and portal hypertensive gastrropathy in liver cirrhotic patients.Methods:Helicobacter pylori infection,IL-1,IL-8,TNF-?,Endotoxin,NO,ET,anti-VacA and anti-CagA levels were determined in cirrhotic patients by using rapid urease test,()~(14)C-urea expiratory test,immunoimpression test,nitrite colorimetric test and ELISA.The parameters of portal venous system flow were determined by doppler ultrasonography.Results:HP prevalence in patients with liver cirrhosis was 77.1%,anti-VacA and antiCagA positive rate was 60.4% in common.IL-1,IL-8,TNF-?,Endotoxin,NO and ET levels in anti-VacA and anti-CagA positive group were significantly higher than in anti-VacA and anti-CagA negtive group.The amount of splenic venous flow(SVF) and superior mesenteric venous flow(SMVF)in anti-VacA and anti-CagA positive group was greater and the amount of portal venous flow(PVF) was smaller than those in negtive group.Conclusion:There was the effect of Helicobacter pylori infection on hyperdynamic circulatory state and portal hypertensive gastrropathy in liver cirrhotic patients.
