Insights

The urea breath test (UBT) does not correlate with the severity of gastric inflammation in children. This study found no concordance between UBT values and histological findings in pediatric patients.

Area of Science:

  • Pediatric Gastroenterology
  • Diagnostic Accuracy
  • Helicobacter pylori Detection

Background:

  • The urea breath test (UBT) is a non-invasive method for detecting Helicobacter pylori infection.
  • Histological examination of gastric biopsies is the gold standard for assessing the severity of gastritis.

Purpose of the Study:

  • To evaluate the correlation between urea breath test values and the histological severity of gastric mucosal lesions in pediatric patients.
  • To determine if UBT results can reliably indicate the degree of gastritis in children.

Main Methods:

  • Endoscopic examination and biopsy were performed on 40 children (ages 3-17) presenting with abdominal pain and positive UBT results.
  • Histological assessment categorized gastric mucosa into four groups: normal, mild, moderate, and severe antrum gastritis.
  • UBT values were compared against these histological classifications.

Main Results:

  • No clear trend was observed between UBT values and the severity of gastritis.
  • Mean UBT values were 44.07 for normal mucosa, 36.15 for mild gastritis, 48.50 for moderate gastritis, and 52.31 for severe gastritis.
  • These findings indicate a lack of concordance.

Conclusions:

  • The urea breath test does not accurately reflect the histological severity of gastric mucosal lesions in children.
  • UBT results should be interpreted with caution in pediatric populations when assessing gastritis severity.
