Abstract

Background and objectives: Helicobacter pylori (H. pylori) infection is the most common etiology of chronic gastric. H. pylori gastritis would gradually evolve into gastric atrophy, intestinal metaplasia, dysplasia and malignant lesions. Herein, this study aimed to investigate the potential impact of H. pylori colonization density and depth on the severity of histological parameters of gastritis.

Methods: A prospective monocentric study was conducted from December 2019 to July 2022, enrolling patients with confirmed chronic H. pylori infection via histopathological evaluation. H. pylori colonization status was detected by immunohistochemical staining, pathological changes of gastric specimens were detected by hematoxylin eosin staining. Epidemiological, endoscopic and histopathological data were collected.

Results: A total of 1120 patients with a mean age of 45.8 years were included. Regardless of the previous history of H. pylori eradication treatment, significant correlations were observed between the density and depth of H. pylori colonization and the intensity of gastritis activity (all P < 0.05). Patients with the lowest level of H. pylori colonization density and depth exhibited the highest level of mild activity. In whole participants and anti-H. pylori treatment-naive participants, H. pylori colonization density and depth were markedly correlated with the severity of chronic gastritis and gastric atrophy (all P < 0.05). H. pylori colonization density (P = 0.001) and depth (P = 0.047) were significantly associated with ulcer formation in patients naive to any anti-H. pylori treatment. No significant associations were observed between the density and depth of H. pylori colonization and other histopathological findings including lymphadenia, lymphoid follicle formation and dysplasia.

Conclusions: As the density and depth of H. pylori colonization increased, so did the activity and severity of gastritis, along with an elevated risk of ulcer formation.

幽门螺旋杆菌定植密度和深度对胃炎严重程度的影响

背景和目的：幽门螺杆菌（H. pylori）感染是慢性胃病最常见的病因。幽门螺杆菌胃炎会逐渐演变为胃萎缩、肠化生、发育不良和恶性病变。本研究旨在探讨幽门螺杆菌定植密度和深度对胃炎组织学指标严重程度的潜在影响：2019年12月至2022年7月期间开展了一项前瞻性单中心研究，通过组织病理学评估入组了确诊为慢性幽门螺杆菌感染的患者。通过免疫组化染色检测幽门螺杆菌定植状态，通过苏木精伊红染色检测胃标本的病理变化。收集了流行病学、内镜和组织病理学数据：结果：共纳入 1120 名患者，平均年龄为 45.8 岁。无论之前是否接受过幽门螺杆菌根除治疗，幽门螺杆菌定植的密度和深度与胃炎活动的强度之间均存在显著相关性（均为 P 结论：幽门螺杆菌定植的密度和深度与胃炎活动的强度之间存在显著相关性：随着幽门螺杆菌定植密度和深度的增加，胃炎的活动性和严重程度也随之增加，溃疡形成的风险也随之升高。

期刊介绍： Annals of Clinical Microbiology and Antimicrobials considers good quality, novel and international research of more than regional relevance. Research must include epidemiological and/or clinical information about isolates, and the journal covers the clinical microbiology of bacteria, viruses and fungi, as well as antimicrobial treatment of infectious diseases. Annals of Clinical Microbiology and Antimicrobials is an open access, peer-reviewed journal focusing on information concerning clinical microbiology, infectious diseases and antimicrobials. The management of infectious disease is dependent on correct diagnosis and appropriate antimicrobial treatment, and with this in mind, the journal aims to improve the communication between laboratory and clinical science in the field of clinical microbiology and antimicrobial treatment. Furthermore, the journal has no restrictions on space or access; this ensures that the journal can reach the widest possible audience.
