有关n H.pylori感染和相关疾病的防治，国内外已有多部共识发布。2017年以来，我国学者先后制定的《第五次全国幽门螺杆菌感染处理共识报告》《中国慢性胃炎共识意见(2017年，上海)》《全国中西医整合治疗幽门螺杆菌相关“病-证”共识》和《中国幽门螺杆菌根除与胃癌防控的专家共识意见(2019年，上海)》等共识意见，为国内n H.pylori感染和相关疾病的诊治、难治性n H.pylori感染的处理和胃癌的防控发挥了重要作用。随着临床实践和认识的深入，家庭n H.pylori感染的情况逐渐引起关注，其危害不容忽视，有必要制订新的管理策略指导防控。本共识在上述共识意见的基础上，进一步对我国居民家庭n H.pylori感染和相关疾病的防控提供建议，以便于指导临床医师、社区和家庭医生对家庭n H.pylori感染的诊治和管理，从而对我国防控n H.pylori感染、预防胃癌的发生、改善居民健康状况起积极作用。n “,”Infection by n Helicobacter pylori (n H.pylori) emerges as a major health threat for Chinese families and society, due mostly to the high infection rate and healthcare cost that attributed to n H.pylori-related gastrointestinal and extra-gastrointestinal diseases. It is also a heavy economic and health care burden for the country. Since 2017, four major consensus reports for n H.pylori infection control and related disease prevention have been published in China. These consensus suggestions provide general guideline for the management of n H.pylori infection and are critical for n H.pylori related-disease prevention and control. However, no corresponding guidelines and treatment strategies have been designated for management of n H.pylori infection among family members to block its intra-familial transmission and development of related diseases. n H.pylori infection is largely a family-based disease, with the advance of clinical practice and public awareness, the detrimental effects of family-based n H.pylori infection has been increasingly recognized, which requires attention from physicians and public health administrative officials. On the basis of the above, this consensus has brought out the novel notion of “whole family-based n H.pylori infection control and management” to curbn H.pylori intra-familial transmission. The consensus suggestions will be instrumental to prevent n H.pylori spreading among family members, and subsequently reduce gastric cancer incidence and medical expenditures. It will also be helpful to optimize household living style and improve public awareness and health for Chinese residents and society.n
