Insights
Infected mothers are the primary source of Helicobacter pylori (H. pylori) transmission to children. This finding highlights the importance of maternal H. pylori status in pediatric infection risk.
Area of Science:
- Microbiology
- Pediatrics
- Epidemiology
Background:
- Investigating intrafamilial transmission of Helicobacter pylori (H. pylori) infection.
- Examining H. pylori occurrence based on parental infection status in a German birth cohort.
Purpose of the Study:
- To determine the primary source of H. pylori infection in children within a family setting.
- To quantify the association between parental H. pylori status and child infection.
Main Methods:
- Longitudinal study of a community-based birth cohort in Germany.
- H. pylori infection assessed using C-urea breath test and monoclonal antigen stool test.
- Parental and child infection status determined at birth and age 3 years, respectively.
Main Results:
- 2.4% of children (20 of 834) were infected with H. pylori by age 3.
- Maternal H. pylori infection significantly increased the odds of child infection (OR=12.9).
- Paternal infection showed a weaker, non-significant association with child infection (OR=1.4).
Conclusions:
- Infected mothers represent the main source of H. pylori transmission to their children.
- Maternal H. pylori status is a critical factor in pediatric H. pylori acquisition.
- Further research into maternal-to-child H. pylori transmission pathways is warranted.
Background:
To further elucidate the intrafamilial transmission of Helicobacter pylori infection, we investigated the occurrence of infection by parental infection status in a large community-based birth cohort of children from Germany.
Methods:
Parental infection (at birth) and children's infection (at age 3 years) were determined by C-urea breath test and by monoclonal antigen stool test.
Results:
Twenty of 834 children (2.4%) were found to be infected. The odds ratio for H. pylori infection of the child was 12.9 (95% confidence interval = 3.2-52.5) if the mother was infected and 1.4 (0.4-4.6) if the father was infected, after adjustment for infection status of the other parent and for nationality. The number of older siblings was not a risk factor for H. pylori infection of the child.
Conclusions:
This longitudinal study suggests that infected mothers are the main source of H. pylori infection of their children.
