Long-term follow up of patients with gastritis associated with Helicobacter pylori infection.

Abstract

The aim of this study was to evaluate the long-term prognosis for patients suffering from gastritis associated with Helicobacter pylori infection, and in particular the proportion of cases progressing to peptic ulcer. The study was carried out in one urban general practice. One hundred and three patients who had presented with dyspepsia over the 1973-80 period and who were found to have a macroscopically normal endoscopy were reassessed between seven and 14 years later. Gastric antral biopsies had been taken routinely at endoscopy and were subsequently re-examined for the presence of H pylori. The patients' medical records were examined to establish their consulting rates over the follow-up period and whether they suffered from any other medical conditions. Patients were interviewed to assess the course of their dyspeptic symptoms. Comparison of patients who were unequivocally H pylori positive with those who were negative revealed no significant differences in the consultation rate for gastroenterological symptoms, in the proportion of patients referred to a hospital consultant or for further gastroenterological investigations or in the proportion reporting that their symptoms had improved. However, a statistically highly significant relationship was found between H pylori infection and hypertension. The results of this study have shown that there is a good prognosis for non-ulcer dyspepsia whether or not H pylori infection is present. The association between H pylori gastritis and hypertension clearly merits further investigation.
