Objective: The objective was to survey the results of RUT (rapid urease test) in children tonsillar tissues.
Methods: In a prospective clinical study 285 children (4–14 years) tonsillar tissue tested with RUT (rapid urease test) and histopathologic biopsy and simultaneously serum IgG Helicobacter pylori level was measured for all patients.
Results: One hundred and thirteen patients (39.6%) were positive to H. pylori in histopathologic
examination. Forty patients (14%) had positive RUT and 15 patients had positive serum IgG anti-H. pylori level. In 40 patients the results in both histopathology and RUT were positive (P = 0.000) although in 172 patients the results in both histopatologhic and RUT were negative (P = 0.000).
Conclusions: This study showed that H. pylori was present in tonsillar tissue and RUT is not sensitive enough for diagnosis of H. pylori in tonsillar tissue. Indicating that H. pylori has a possible role in reservoir of H. pylori in children.
