ABSTRACT
The objectives of this study were to evaluate the methods used to diagnose Helicobacter pylon infection in gastric biopsies, and to evaluate the correlation between H. pylori infection and clinical outcomes. Gastric biopsies, obtained from 210 patients, were evaluated for H. pylori by culture, a commercial rapid urease test (RUT, Pronto Dry) and histological examination. A true positive result was either the culture or both the RUT and histological examination were positive. The results showed a H. pylori infection rate of 44.3% (93/210). The sensitivities, specificities, positive predictive values and negative predictive values were 88.2, 100, 100, and 91.4 % by the culture; 95.7, 98.3, 97.8, and 96.6% by RUT; and 96.8, 59.8, 59.8, and 65.7% by histological examination, respectively. The prevalences of H. pylori in non-ulcer dyspepsia (NUD), peptic ulcer dyspepsia (PUD) and gastric cancer (GCA) patients were 41.2, 57.9 and 70.6%, respectively. The chi-squared-test showed that GCA patients were significantly more frequent infected with H. pylori than NUD patients (p<0.05). Our study indicates that the RUT method was highly sensitive, specific and appropriate for routine clinical use.
