Insights
Helicobacter pylori infection is more common in children with constitutional delay of growth and puberty (CDGP). This suggests H. pylori may contribute to growth and pubertal delays in pediatric patients.
Area of Science:
- Pediatrics
- Infectious Diseases
- Gastroenterology
Background:
- Helicobacter pylori is a common gastroduodenal pathogen linked to gastritis and ulcers.
- H. pylori infection is hypothesized to be a potential cause of growth retardation in children.
- Constitutional delay of growth and puberty (CDGP) affects children's physical development.
Purpose of the Study:
- To investigate the seroprevalence of H. pylori in children diagnosed with CDGP.
- To compare H. pylori infection rates between children with CDGP and healthy controls.
Main Methods:
- Serological testing for H. pylori IgG antibodies was performed.
- The study included 24 children with CDGP and 32 age-matched healthy controls.
- Statistical analysis was used to compare infection rates between groups.
Main Results:
- H. pylori IgG positivity was found in 66.6% of children with CDGP.
- In the control group, 37.5% tested positive for H. pylori IgG.
- A significantly higher prevalence of H. pylori was observed in children with CDGP (p <0.05).
Conclusions:
- The study supports the hypothesis that H. pylori infection may be an environmental factor contributing to CDGP.
- Findings suggest a potential link between H. pylori and delayed growth and puberty in children.
- Further research is warranted to elucidate the role of H. pylori in pediatric growth disorders.
Abstract:
Helicobacter pylori is a gastroduodenal pathogen strongly associated with chronic gastritis and duodenal ulceration. It is thought that H. pylori infection might be one of the causes of growth retardation in children. The aim of this study was to evaluate the seroprevalence of H. pylori in children with constitutional delay of growth and puberty (CDGP). H. pylori seropositivity was studied in 24 children with CDGP (22 M, 2 F) and 32 healthy age-matched children with normal pubertal development. Mean age of the children with CDGP was 14.53 +/- 1.12 yr and all of them had been diagnosed as CDGP after physical and laboratory assessment. H. pylori IgG positivity was detected in 16 of the 24 children with CDGP (66.6%) and 12 of 32 controls (37.5%) (p <0.05). This finding is consistent with the hypothesis that H. pylori infection could be one of the environmental factors causing CDGP.

Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
