Risk of esophageal adenocarcinoma in patients with Barrett’s esophagus using proton pump inhibitors: a systematic review with meta-analysis and sequential trial analysis

BACKGROUND: Proton pump inhibitors (PPIs) have been used to treat Barrett’s esophagus (BE), but there seems to be insufficient evidence that PPIs can prevent esophageal adenocarcinoma (EAC) and high grade dysplasia (HGD). This study aimed to evaluate the effects of PPIs in BE patients. METHODS: PubM...

Sumario:BACKGROUND: Proton pump inhibitors (PPIs) have been used to treat Barrett’s esophagus (BE), but there seems to be insufficient evidence that PPIs can prevent esophageal adenocarcinoma (EAC) and high grade dysplasia (HGD). This study aimed to evaluate the effects of PPIs in BE patients. METHODS: PubMed and EMBASE were systematically searched. Stata13 and trial sequential analysis (TSA) software were used to carry out related statistics. Pooled odds ratio (OR) with 95% confidence intervals (CIs) were calculated. RESULTS: Using PPIs to reduce the incidence of EAC and HGD has not been confirmed (OR, 0.61; 95% CI, 0.29–1.26). The pooled results of three cohort studies reported that PPIs use was protective (OR 0.48; 95% CI, 0.33–0.70). But the pooled results of five case-control study indicating PPIs use does not prove this protective effect (OR 0.73; 95% CI, 0.21–2.48). On pooled analysis of 4 US studies 2 Netherlands, protective effect on development of EAC and HGD was noted (OR, 0.59; 95% CI, 0.43–0.80) and (OR, 0.16; 95% CI, 0.03–0.75). CONCLUSIONS: According to the Meta analysis and TSA of existing studies, the protective effect of PPIs on the progression of BE patients to EAC and/or HGD has not been confirmed. TSA shows that more patients are needed before a clear conclusion can be reached.
