Prevalence of Helicobacter pylori in Northern Jordan. Endoscopy based study.
OBJECTIVE
Helicobacter pylori infection is considered the most common infection worldwide and is associated with many other disorders. The aim of this study is to determine the prevalence of this infection among patients undergoing endoscopy in Northern Jordan.


METHODS
Between November 1998 and September 2000, all patients referred from the Gastro-esophageal Clinic to the Endoscopy Unit at Princess Basma Teaching Hospital, Irbid, Northern Jordan were enrolled in this prospective study. For each patient clinical and epidemiological data was collected and endoscopy was performed. At least 3 antral biopsies were obtained from each patient, and these were examined histologically for the presence of gastritis and stained for Helicobacter pylori using modified Giemsa stain.


RESULTS
A total of 197 consecutive patients (113 females) with a mean age of 40.2 years (range 15-91 years) were studied. Abdominal pain was the highest presenting symptom. Gastritis 91% and esophagitis 42% were the most frequent endoscopic findings. Gastritis was documented histologically in 183 (93%) of patients. Helicobacter pylori was found in 161 patients (82%), with all of these having histological gastritis. The 11 patients with gastric ulcer, compared to the 51 out of the 59 (86%) patients with duodenal ulcer, showed Helicobacter pylori in their biopsies.


CONCLUSIONS
The prevalence of Helicobacter pylori infection in patients subjected to an upper gastrointestinal endoscopy in Jordan is high. This study confirms that Helicobacter pylori is significantly associated with gastritis and peptic ulcer. Further studies are needed to determine the types of Helicobacter pylori strains present in Jordan.
