    Abstract:
    In a prospective study, gastroscopy and biopsies from the gastric antrum and body were undertaken in 100 consecutive patients (67 women, 33 men; mean age 58.6 [11-90] years) with unknown Helicobacter pylori status. None had been on any bacteria-suppressing drugs. Main indications for gastroscopy were upper abdominal pain, dyspepsia, emesis and anaemia of unknown cause. The macroscopic criteria for the diagnosis of H. pylori gastritis were the presence of at least one of the following signs: (1) chronic antral erosions; (2) goose-pimple-like appearance of the antral mucosa; (3) spotty erythema in the antrum; (4) complex changes of the antral mucosa with both bizarre reddening and pale areas; and (5) increased areolar markings and diffuse or fine-spotty erythema in the mucosa of the body of the stomach. Four biopsies each from the antrum and body were examined with the urease quick-test, microscopically as smears, specific culture and histology as reference methods. 60 patients had H. pylori gastritis, recognized macroscopically in 59 (sensitivity 98.3%). A false-positive diagnosis was made in 10 of 40 H. pylori-negative patients (specificity 75%). The positive predictive value of macroscopic diagnosis was 85.5%, the negative predictive value 96.8%.
