But How Well Does It Work in Theory and Eosinophilic Esophagitis Treatments

C Mayerhofer et al. Clin Gastroenterol Hepatol 2023; 21: 2197-2210. Open Access! Efficacy of Elimination Diets in Eosinophilic Esophagitis: A Systematic Review and Meta-analysis

“That’s all well and good in practice… but how does it work in theory?” I saw this quote many years ago when I was visiting the University of Chicago.

This quote came to mind as I was reading this article which showed relatively little change in the efficacy between more and less stringent elimination diets for eosinophilic esophagitis. This meta-analysis included 915 children and 847 adults and assessed the efficacy rates of 4 major dietary treatment regimens in eosinophilic esophagitis: 6-food (SFED), 4-food (FFED), 1-food (OFED), and a targeted elimination diet (TED).

Key findings:

• The overall rate of histologic remission was 53.8% and in the individual dietary groups was 61.3% for SFED, 49.4% for FFED, 51.4% for OFED, and 45.7% for TED.
• The overall rate of clinical response was 80.8%, with response rates of 92.8% for SFED, 74.1% for FFED, 87.1% for OFED, and 69.0% for TED.

My take: It is clear to me that more restrictive diets can yield better response rates; however, in clinical practice they are difficult to maintain and this study shows that the improvement with more food restrictions may be quite limited.

Another reference on eosinophilic esophagitis: CJ Ketchem et al. Clin Gastroenterol Hepatol. 2023 Aug;21(9):2252-2259. Open Access! Higher Body Mass Index Is Associated With Decreased Treatment Response to Topical Steroids in Eosinophilic Esophagitis. Key finding: Histologic response (n=296) to topic steroids was higher for those who were nonobese compared with obese at fewer than 15 eosinophils per high-power field (61% vs 47%; P = .049); in addition, nonobese patients had significantly greater endoscopic and symptomatic responses.
