FRIDAY, Oct. 21 (HealthDay News) -- Inflammation and enlargement
of adenoids in children does not appear to be caused by bacteria
associated with stomach inflammation and ulcers, researchers
The condition, also known as adenoid hyperplasia, causes upper
airway obstruction and is associated with thinking and behavioral
problems in children. It's been suggested that adenoid hyperplasia
may be caused by gastrointestinal reflux disease (GERD) -- a
condition in which stomach contents back up into the esophagus --
or a similar condition called laryngopharyngeal reflux (LPR).
In this study, Australian researchers investigated whether
ulcer- and stomach-inflammation causing
Helicobacter pylori bacteria and/or related bacteria were
found in tissue samples from 78 hyperplastic and 15 normal adenoids
from children aged 2 to 10.
No evidence of
H. pylori was found in any adenoid tissue sample, which
contained very few bacterial organisms overall.
The findings challenge other studies that claimed to find high
H. pylori in adenoid tissue, the researchers said.
"We believe that our findings show that adenoid tissue does not serve as a reservoir for species of the Helicobacteraceae family," wrote Damian J. Hussey and colleagues at Flinders Medical Centre and Flinders University in Adelaide. "This suggests that colonization of the tissue by these bacteria is not a factor contributing to adenoid hyperplasia."
The study appears in the October issue of the
Archives of Otolaryngology -- Head & Neck Surgery.
