Background: Helicobacter pylori is now recognized as a causative factor of chronic gastritis, gastroduodenal ulcers, gastric cancer and mucosa-associated lymphatic tissue lymphoma. Toll-like receptors are important bacterial receptors in gastric epithelial cell signaling transduction and play critical roles in gastric carcinogenesis. Materials and Methods: A total of 400 patients undergoing esophagogastroduodenoscopy for investigation of chronic abdominal pain were genotyped for single-nucleotide polymorphisms (SNPs) in TLR1 (rs4833095) using TagMan SNPs genotyping assay by real-time PCR hybridization. Relationships with susceptibility to H. pylori infection and pre-malignant gastric mucosa morphological patterns, classified by magnifying NBI endoscopy, were investigated. Results: The percentages of TLR1 rs4833095, CC homozygous, CT heterozygous and TT homozygous cases were 34, 46.5 and 19%, respectively. CC showed statistical differences between H. pylori positive and negative cases (P<0.001). CT and TT correlated with type 1 and type 2 gastric mucosal morphological patterns (P <0.01) whereas CC correlated with types 3 and 4 (P<0.01). Conclusions: This study demonstrated good correlation of TLR1 rs4833095 genotype with severity of inflammation in H. pylori infected gastric mucosa according to gastric mucosal morphologic patterns with magnifying NBI endoscopy.
