Abstract

OBJECTIVE

H. pylori infection in children has a high prevalence worldwide. The disease can cause progressive gastric mucosal inflammation, as verified in animal models. However, data from large-scale clinical studies are limited.

METHODS

We examined 1,634 Chinese children with upper gastrointestinal discomfort using endoscopy. The clinical and pathological data of the patients were analyzed.

RESULTS

A total of 524 (32.1%) patients were infected with H. pylori, and the prevalence of H. pylori infection increased with age. The H. pylori-infected patients exhibited a significantly higher prevalence of active inflammation (26.9% vs. 4.1%), lymphoid follicle formation (18.5% vs. 4.6%) and marked lymphocyte infiltration (19.7% vs. 5.6%). The H. pylori-infected patients also exhibited a significantly higher prevalence of moderate to marked chronic superficial gastritis (41.9% vs. 9.2%) and moderate chronic atrophic gastritis (21.7% vs. 2.6%) than the uninfected patients (p<0.01).

CONCLUSION

H. pylori infection is associated with the degree of gastric mucosal inflammation and the severity of different types of chronic gastritis.

摘要

目的

幽门螺杆菌感染在全球儿童中具有较高的患病率。在动物模型中已证实，该疾病可导致进行性胃黏膜炎症。然而，大规模临床研究的数据有限。

方法

我们对1634名有上消化道不适症状的中国儿童进行了内镜检查。对患者的临床和病理数据进行了分析。

结果

共有524名（32.1%）患者感染了幽门螺杆菌，幽门螺杆菌感染率随年龄增长而升高。幽门螺杆菌感染患者的活动性炎症（26.9%对4.1%）、淋巴滤泡形成（18.5%对4.6%）和明显的淋巴细胞浸润（19.7%对5.6%）患病率显著更高。幽门螺杆菌感染患者的中度至重度慢性浅表性胃炎（41.9%对9.2%）和中度慢性萎缩性胃炎（21.7%对2.6%）患病率也显著高于未感染患者（p<0.01）。
