Serum VEGF Levels in Helicobacter pylori Infection and Correlation with Helicobacter pylori cagA and vacA Genes
BACKGROUND Helicobacter pylori vacA and cagA genes are associated with higher virulence. Vascular Endothelial Growth Factor (VEGF) is one important marker for neo-angiogenesis. AIM The purpose of this study was to investigate the relationship between VEGF serum levels with cagA and vacA genes in H. pylori infection. METHODS A cross-sectional study was done on eighty patients that consecutiv...

متن کاملEPIYA motif patterns among Cuban Helicobacter pylori CagA positive strains.
INTRODUCTION It is known that polymorphisms in C-terminal region of CagA influence gastric disease development on Helicobacter pylori infection. Additionally, the geographic distribution of these polymorphisms has been associated with the appearance of more severe gastroduodenal pathologies. Objective. To determine the CagA phosphorylation motifs pattern (EPIYA pattern) in Cuban H. pylori isola...
متن کاملPrevalence of infection with cagA-positive Helicobacter pylori strains among children and adolescents in southern Brazil.
CONTEXT Helicobacter pylori (H. pylori) has a worldwide distribution, but the prevalence of infection, virulence factors, and clinical presentation vary widely according to the studied population. In Brazil, a continental country composed of several ethnicities and cultural habits, the behavior of infection also appears to vary, as many other studies have shown. OBJECTIVES Describe the preval...
