Helicobacter pylori prevalence in northeastern Thailand.
Helicobacter pylori is distributed worldwide and has been demonstrated in Thailand. However, no study has been conducted so far in northeastern Thailand. The objective of this study was to find the prevalence of H. pylori in patients undergoing upper gastrointestinal endoscopy in northeastern part of Thailand. One hundred and twenty-six patients undergoing surgery between November 1992 and January 1993 were studied. Biopsies were done at antrum, corpus, and other positive lesions. Diagnostic tests of H. pylori by using CLO test, microbiological tests (Gram stain and culture), and histological examination (hematoxylin and eosin) were carried out. The prevalence of H. pylori by CLO test, Gram stain, culture, and histology were 49.2%, 61.9%, 22.2%, and 45.2% respectively. The overall prevalence of H. pylori by all diagnostic tests was 73.8% (95% confidence interval = 66.1-81.5%). This study revealed a high prevalence rate of H. pylori in patients which should alert clinicians who practice in this geographical area.
