Abstract

Background and Study Aims: We attempted to determine whether the serological titer of anti-Helicobacter pylori (HP) immunoglobulin (IgG) would be capable of predicting the presence of ulcer, or would correlate with the histological grading of gastritis in patients with dyspepsia. Patients and Methods: One hundred eighty-three dyspeptic patients were prospectively included in the study after panendoscopy. Each patient underwent blood sampling for anti-HP IgG titer, and antral biopsy for both a rapid urease test (CLO) and histology. The severity of antral gastritis was semi-quantitated for acute and chronic inflammation scores (range 0-3). Results: The HP findings were positive in 157 patients (85.5%), and their histological inflammation scores and serological titer were higher than those of HP-negative patients (P < 0.05). Based on the endoscopic findings, these 157 patients were classified into ulcer (n = 109) and non-ulcer dyspepsia (n = 48) subgroups. The mean chronic inflammation score in the ulcer subgroup was higher than that in the non-ulcer dyspepsia subgroup (1.77 vs, 1.28, P < 0.001). However, on the basis of only the titer itself, there was no cut-off value for serological titer to predict the presence or absence of ulcer in HP-infected patients. As the scores for either acute or chronic inflammation increased, the mean serological titer rose (acute inflammation score 0-3: 0.63, 0.78, 0.93, 1.39; chronic inflammation score 0-3: 0.18, 0.56, 0.88, 0.91). Conclusions: The titer of HP serology does not provide a method for predicting the presence of ulcer in patients with HP infection, but may indirectly offer evidence of the severity of histological changes.
