A recent study published online (here’s a link: EoE 4-food Group Diet) shows that a four food elimination diet was effective in 54% of the adults in this study. Here’s the abstract:
Eosinophilic esophagitis (EoE) is an esophageal disorder predominantly triggered by food antigens. A six-food group elimination diet (SFGED) achieves remission in more than 70% of adult patients with EoE. After individual food reintroduction, just 1 or 2 food triggers for EoE can be identified in 65% to 85% of the patients, so some dietary restrictions and endoscopies after food challenge may be unnecessary.
To evaluate the efficacy of a four-food group elimination diet (FFGED) (dairy products, wheat, egg, and legumes) for adult patients with EoE.
Prospective multicenter study. All patients were reevaluated after 6 weeks on an FFGED. Response to the FFGED was defined by clinical and histologic (<15 eos/hpf) remission. Responders underwent reintroduction of each individual food over 6 weeks followed by endoscopy and esophageal biopsies. Nonresponders were offered a rescue SFGED.
A total of 52 adult patients were included, of whom 12 patients (23%) had previous failure to topical steroid therapy. Twenty-eight of the 52 patients (54%) achieved clinicopathologic remission on the FFGED and 6 of the 19 (31%) nonresponders to the FFGED were successfully rescued with the SFGED. Twenty-two of 28 responders to the FFGED (78%) finished the individual food reintroduction challenge. Milk was identified as an EoE trigger in 11 patients (50%), egg in 8 (36%), wheat in 7 (31%), and legumes in 4 (18%). All patients had just 1 or 2 food triggers, with milk being the only causative food in 27% of the patients.
An FFGED achieved clinicopathologic remission in 54% of adult patients with EoE. An SFGED was effective in almost a third of FFGED nonresponders, resulting in a combined efficacy of 72% of both strategies.
