Prevalence of Helicobacter pylori infection among new outpatients with dyspepsia in Kuwait

<p>Abstract</p> <p>Background</p> <p>Testing and treatment for <it>Helicobacter pylori </it>has become widely accepted as the approach of choice for patients with chronic dyspepsia but no alarming features. We evaluated <it>H. pylori </it>status among outpatients with uninvestigated dyspepsia in Kuwait.</p> <p>Methods</p> <p>A prospectively collected database for 1035 patients who had undergone ¹³C-urea breath tests (UBT) for various indications was reviewed for the period from October 2007 to July 2009. The status of <it>H. pylori </it>in dyspeptic patients was determined by UBT.</p> <p>Results</p> <p>Among the 362 patients who had undergone UBT for uninvestigated dyspepsia, 49.7% were positive for <it>H. pylori </it>(95% CI = 44%-55%) and the percentage increased with age (35.8% at 20-29 years, 95% CI = 25.4% - 47.2%; 59.3% at 30-39 years, 95% CI = 48.5% - 69.5%) (P = 0.013). The prevalence of <it>H. pylori </it>was 42.6% among Kuwaitis (95% CI = 35%-50%) and 57.6% (95% CI = 49.8%-65%) among expatriates (p = 0.004). The prevalence among males was 51.3%, while in females it was 48.6%.</p> <p>Conclusions</p> <p>Almost half of the patients with dyspeptic symptoms in Kuwait were positive for <it>H. pylori</it>, though the prevalence varied with age and was higher among expatriates. The American Gastroenterology Association guidelines recommending testing and treatment for <it>H. pylori </it>for patients with uninvestigated dyspepsia should be endorsed in Kuwait.</p
