Abstract
Helicobacter pylori infection can be diagnosed by
invasive methods using the gastric biopsied specimens or
non invasively by examining serum, urine, breath, or stool.
Histological examination by Giemsa staining is usually
recommended for the diagnosis, but it is difficult to
visualize the bacterium when there is alow density of
H.Pylori on the gastric mucosa with atrophic and
metaplastic changes (Kokkola, 2000).
Limitations of histological examination include
increased false negative test findings due to various density
of H. pylori at a different sites, high cost, long turn around
time, and inter observer variability. Therefore, in endemic
countries like Egypt with s higher risk of chronic atrophic
gastritis (CAG), intestinal metaplasia, and gastric cancer,
noninvasive tests need to be added for a more reliable
diagnosis of H.Pylori infection (Talebkhan, 2009).
We aimed in this study to compare between the
prevalence of chronic atrophic gastritis (CAG) and gastric
corpus atrophy in Helicobacter pylori-seropositive subjects
according to the stool antigen test, serum pepsinogen(PG)
level and upper endoscopic findings.
The current study represents Cross- sectional study -
Descriptive -Diagnostic study. This study had been carried
at Ain Shams University and Abbasia fever hospital on 80 seropositive- patients attending to endoscopy ward for a
regular check-up.
All patients subjected to full history, clinical
examination and investigation in the form of; complete
blood count, serum anti-H.Pylori immunoglobulin G (IgG),
stool antigen test and serum pepsinogen.
The current study showed that there was a significant
difference between positive and negative H. pylori
regarding pepsinogen I & II and endoscopic finding
regarding CAG and CSG.
