Abstract
OBJECTIVES
H. pylori infection and NSAID are very
important risk factors for peptic ulcer. This study was
conducted to investigate the H. pylori positivity rate and
the rate of NSAID ingestion in the patients with benign
gastric ulcer(BGU), to investigate which test and which
site are the most adequate to reduce the false positivity
rate of H. pylori, and finally to investigate the role of H.
pylori and NSAID in BGU bleeding.
METHODS
This study was conducted for the 180
patients with BGU, and H. pylori was diagnosed by any
of CLO test, Gram stain of touch print and H&E stain in
the antrum and body. In addition, age, sex, ingestion
history of NSAID within 4 weeks before gastroscopy,
past BGU history, smoking, alcohol and BGU bleeding
were investigated.
RESULTS
1) The H. pylori infection rate of patients with BGU in
Korea was 82.8%, and the rate of NSAID history was
26.1%. The patients with BGU who have only NSAID
history were 8.3%, and the 91.1% of the patients had
either H. pylori infection or NSAID history.
2) The most sensitive test for H. pylori infection
among CLO test, Gram stain of touch print and H&E
stain in the antrum or body was CLO test in the body.
3) Depending on H. pylori positivity, the rate of
NSAID history in the H. pylori negative group was
48.4%, which was higher than that of H. pylori positive,
21.5%(p=0.002). In addition, the rate of past BGU history
in the H. pylori positive group was 47.0%, which was
higher than that of H. pylori negative, 12.9%(p<0.001).
4) Depending on the history of NSAID, the H. pylori
positivity rate in NSAID positive group was 68.1%, which
was lower than that of NSAID negative, 88.0%(p=0.002).
The female percentage of NSAID positive was 40.4%,
which was higher than that of NSAID negative, 16.5%
(p<0.001). The rate of BGU bleeding in the NSAID
positive was 27.7%, which was higher than that of
NSAID negative, 14.3%(p=0.039).
5) The rate of NSAID history of bleeding group was
40.6%, which was higher than that of non-bleeding
group, 23.0%(p=0.039). However, there was no signifi
cance in the correlation of H. pylori positivity rate to the
bleeding.
6) The H. pylori positivity and NSAID history showed
no correlation with bleeding in the group below age sixty.
While in the age over or equal to sixty the H. pylori
positivity had no correlation with bleeding, but the rate of
NSAID history was 72.7% for the patients with bleeding,
which is in contrast with the 25.5% for the patients
without bleeding(p=0.003).
CONCLUSION
From these results, the H. pylori
infection rate of the patients with BGU in Korea was
82.8%, and the best method for H. pylori detection was
CLO test in the body. H. pylori infection had no corre
lation with the bleeding, but NSAID ingestion increased
bleeding tendency, particularly in the group of the age
over or equal to sixty.
