Abstract
BACKGROUND
Barrett's esophagus (BE) is an important risk factor for high-grade dysplasia (HGD) and/or esophageal adenocarcinoma (EAC). The effect of proton pump inhibitors (PPIs) on the chemoprevention of HGD and/or EAC arising from BE remains controversial.
RESEARCH DESIGN AND METHODS
PubMed, EMBASE, and Cochrane Library databases were systematically searched. Risk ratios (RRs) or odds ratios (ORs) with 95% confidence intervals (CIs) were pooled by a random-effect model. Heterogeneity and its potential source were assessed.
RESULTS
Fifteen studies with 26,291 BE patients were included. Meta-analysis of eight cohort studies showed that PPIs can significantly reduce the risk of HGD and/or EAC in BE patients (RR = 0.46; P < 0.001), but meta-analysis of six case-control studies showed no significant benefit of PPIs (OR = 0.64; P = 0.334). Heterogeneity was significant among both cohort and case-control studies, which might be attributed to the information sources of PPIs. There was no significant protective effect of high-dose PPIs on HGD and/or EAC in one RCT (RR = 0.84; P = 0.21), meta-analysis of two cohort studies (RR = 0.61; P = 0.28), or meta-analysis of two case-control studies (OR = 0.32; P = 0.08).
CONCLUSIONS
Chemoprevention of HGD and/or EAC by PPIs may be considered in BE patients. However, there might not be further preventive effect of high-dose PPIs.
