Abstract
SUMMARY
The arm of this work is to evaluate the culture method In
diagnosis of helicobacler pylori in patients with dyspepsia In
comparison to the histological method with modified giemsa staining.
To fulfill this aim ~0 patients with dyspepsia were included.
The patients were subjected to the following:
• Full medical history taking,
• Thorough clinical exanination.
• Routine laboratory investigation.
• Upper gastrointestinal endoscopy and two biopsies were taken for
bacteriological and histological examination.
Helicobacter pylcri was detected by modified giemsa stain in 30
patients out of 50 (60%) and could be isolated by culture in 18 patients
(36%) all of them were positive RP. by modified giemsa. So when
modified giemsa is considered as a reference test senstivity, specificity,
positive predictive valle and negative predictive value of culture
method respictevely were 53.3%, 90%, 88.9% and 56.3%.
As regard age and sex the incidence ofH.P. had no statistically
significant difference in different age groups and in both sexes
H.P. could be de tected in 7 patients out of 8 with peptic ulcer
(87.5%) and in 5 ou: of 6 with duodenal ulcer (83.3%) with a
statistically significant difference between patients with peptic ulcer
and those without.
H.P. could be detected in 11 out of 12 patients of dyspepsia with
endoscopic picture of gastritis (92%).
H.P. could be detected in 13 out of24 dyspeptic patients with
chronic liver disease (5l%) and in 17 out of 26 dyspeptic patients
without chronic liver disease with no statistically significant difference.
Endoscopic gastriis was found in 8 patients out of 35 dyspeptic
patients with histologies I gastritis (22.8%) and in 3 patients out of 15
patients without hsitological gastritis (20%) with no statistically
significicant correlation b etween endoscopic and histologic gastritis.
