Chinese Consensus Report on Family-BasedHelicobacter pyloriInfection Control and Management (2021 Edition)

Abstract

Objective Helicobacter pyloriinfection is mostly a family-based infectious disease. To facilitate its prevention and management, a national consensus meeting was held to review current evidence and propose strategies for population-wide and family-basedH. pyloriinfection control and management to reduce the related disease burden. Methods Fifty-seven experts from 41 major universities and institutions in 20 provinces/regions of mainland China were invited to review evidence and modify statements using Delphi process and grading of recommendations assessment, development and evaluation system. The consensus level was defined as ≥80% for agreement on the proposed statements. Results Experts discussed and modified the original 23 statements on family-basedH. pyloriinfection transmission, control and management, and reached consensus on 16 statements. The final report consists of three parts: (1)H. pyloriinfection and transmission among family members, (2) prevention and management ofH. pyloriinfection in children and elderly people within households, and (3) strategies for prevention and management ofH. pyloriinfection for family members. In addition to the ‘test-and-treat’ and ‘screen-and-treat’ strategies, this consensus also introduced a novel third ‘family-basedH. pyloriinfection control and management’ strategy to prevent its intrafamilial transmission and development of related diseases. Conclusion H. pyloriis transmissible from person to person, and among family members. A family-basedH. pyloriprevention and eradication strategy would be a suitable approach to prevent its intra-familial transmission and related diseases. The notion and practice would be beneficial not only for Chinese residents but also valuable as a reference for other highly infected areas.
