Abstract

Background: Eosinophilic oesophagitis (EoE) is a growing cause of dysphagia. Current therapies include dietary manipulation, steroids and biological drugs. Aim: To perform a systematic review and summarise the effect of different medical interventions on EoE. Methods: Two reviewers searched Pubmed and Embase for studies on treatment for EoE. We included randomised controlled trials (RCT) limited to pharmacological interventions. Two reviewers selected studies. Meta-analysis was done using random effects model to estimate odds ratio (OR). Heterogeneity was determined by Cochran's Q statistic and I2. Results: Seventeen references met our inclusion criteria. Eleven RCTs involving 455 participants were included in the meta-analysis. 325 participants were evaluated for symptomatic improvement and 330 were evaluated for histological remission. Symptomatic improvement with topical steroids (7 studies, 250 participants) compared to the control group (placebo or PPI) was noted (OR: 3.03, 95% confidence interval, CI: 1.57-5.87). Histological remission was also noted in nine studies involving 330 participants (OR: 13.66, 95% CI: 2.65-70.34) comparing topical steroids to a control (placebo or PPI). There was no difference between anti-IL-5 drugs and placebo in terms of symptomatic improvement (OR: 0.69, 95% CI: 0.34-1.42). Conclusions: Topical steroids induce significant symptomatic and histological remission, and should be considered as a first line treatment. Anti-IL-5 therapy has a minor effect on eosinophilic oesophagitis. Future research in eosinophilic oesophagitis should standardise methodology according to published guidelines to improve quality and allow direct comparison between therapies.
