One year treatment of Barrett's oesophagus with proton pump inhibitors (a multi-center study)
Abstract
OBJECTIVES: Aim of the study was to investigate the effects of 1-year therapy by different proton pump inhibitors (PPIs) on epithelial tissue and surrounding inflammatory changes in Barrett's oesophagus, in patients who have abandoned invasive therapy.
METHODS: A group of 120 patients (sampled in 60-month period, from 61201 upper gastrointestinal endoscopies) who were diagnosed both, endoscopically and pathohistologically with Barrett's oesophagus, and who have abandoned invasive therapeutic approach were enrolled in study. Treatment with different PPIs was initiated and continued for a year. At the end of treatment, patients were reassessed by endoscopy with tissue biopsy and pathohistological analysis.
RESULTS: No difference in regenerating squamous epithelium or degree of dysplasia was seen between different treatment groups. Interestingly, most patients receiving pantoprazole (94%) ended up with thinner squamous epithel (P<0.0001). The squamous epithel was consider thinner only if its total thickness, measured on histological specimen, was smaller for more than 50% of the thickness before therapy. Significantly less of difference (P<0.0014) was seen with patients receiving lansoprazole (65%) and (P<0.003) omeprazole (50%).
CONCLUSION: Regeneration of the squamous epithel was the same for all PPIs but not good enough to stop the progression of the disease.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 120 participants or records.
