Abstract |
Purpose : The aim of the present study was to assess the clinical, endoscopic and
histologic findings of the Helicobacter pylori(Hp)-associated gastritis in children.
Methods : We have assessed 91 patient(age range 3-15 years) referred for upper
intestinal endoscopy during 17 months. At least two antral biopsies were taken during
endoscopy. The histological analysis and CLO test were done. The histologic changes
were scored and semiquantitative assessment of the degree of Hp colonization was
performed using Giemsa' stain.
Results : 1) Helicobacter pylori(Hp) was detected by CLO test and/or histologic analysis in 35 patients(38.5%). The CLO test was positive in 25 cases and H.pylori was colonized histologically in 10 patients.
2) The clinical symptoms were not significantly different between Hp positive and Hp
negative patients(p>0.01).
3) Nodular antritis(37.1%) was a frequent endoscopic finding in Hp-infected patients,
particularly in the subgroup with active chronic gastritis(93.8%). All patient with nodular antritis had Hp infection.
4) Helicobacter pylori has been associated both with active chronic gastritis(42.9%)
and with nonactive chronic gastritis(40.0%). The common abnormal histologic finding
was active chronic gastritis(42.9%) in Hp positive patients and nonactive chronic
gastritis(66%) in HP negativepatients. A significant correlation was found between Hp colonization score and the histologic categories(p<0.01).
5) ThefrequencyofHpinfection(positiveness)asrelatedtohistologiccategorieswas:
active chronic gastritis 93.8 %;duodenalulcer66.7%;gastric ulcer33.3 %;nonactive
chronicgastritis27.5%;normal16.7%.
6) The histolgical colonization by Hp was assessed semiquantitatively, and a
significantly greater Hp colonization score was observed in patients with signs of
histological activity(p<0.01).
Conclusion : This study suggests that Hp infection was significantly associated
with endoscopic nodular antritis and the presence of gastroduodenalpathology. |
