ABSTRACT
Background and objectives: Proton pump inhibitors are used widely for gastroesophageal reflux disease and ulcer type dyspepsia. Majority of the patients require long term medication. H2 receptor antagonist are also used for relief of symptoms. Though tachyphylaxis has been reported, symptom response is seen with long term use. The aim of the present study was to study the effects of long-term acid suppressants on gastric antral histology.
Methods: Patients who received long-term acid suppressants such as ranitidine and omeprazole for gastroesophageal reflux disease or dyspepsia were included. All of them had an antral biopsy for histology and H. pylori status at baseline, at 6 months and 12 months. Patients on acid suppressants for less than a year or on long-term non-steroidal anti inflammatory drugs were excluded from the study. The grading of gastritis was classified as chronic active gastritis, atrophic gastritis, intestinal metaplasia and dysplasia.
Results: Thirty patients received ranitidine and 28 omeprazole. In H. pylori positive group, the median duration of ranitidine and omeprazole were 3 years (1.5 to 8 years) and 4 years (1 to 10 years) respectively. Two thirds of patients had chronic active gastritis (ranitidine: 35.5% omeprazole:26.6%); 10 had gastric atrophy (ranitidine: 6.6% omeprazole:15.5%) and 7 had intestinal metaplasia (ranitidine4.4% omeprazole11.1%). Four of the 10 patients on omeprazole showed progression of histology as against only one of the 13 patients on ranitidine at one year of follow up. In omeprazole pylori negative patients, the median duration of ranitidine and omeprazole was 2.5 years (range 1 to 6 years) and 3 years (range 2 to 7 years) respectively. Irrespective of the acid suppressants, the baseline histology was either chronic active gastritis (78.5%) or gastric atrophy (21.5%). None had intestinal metaplasia. Also there was no progression in histology staging during the follow up.
Conclusions: Long-term acid suppressants irrespective of the H. pylori status are not associated with significant histological changes in gastric mucosa. Despite a significant drop out of cases, among the cases followed up no significant progression in histological staging was seen during a one year follow-up. (J Dig Endosc 2013;4(1):1–5)
