PHILADELPHIA – While traditional elimination diets for eosinophilic esophagitis are highly restrictive and endoscopically intensive, a new “step-up” approach may offer a superior empiric scheme for identifying food triggers, according to Stuart J. Spechler, MD.
The recently described step-up approach may be preferable to the standard empiric six-food elimination diet, which has a 72% success rate but is challenging to implement, according to Dr. Spechler, chief of the division of gastroenterology, Baylor University Medical Center at Dallas.
In the standard elimination diet, the most common food allergens (milk, wheat, eggs, soy, nuts, seafood) are removed, and then reintroduced one at a time over 6 weeks, with symptom response assessment and repeat endoscopy after each introduction.
“That’s an extremely demanding, time-consuming, inconvenient, and expensive thing to do. It requires at least seven endoscopies, probably more, performed over a period of 42 weeks,” Dr. Spechler said here at Digestive Diseases: New Advances, jointly provided by Rutgers and Global Academy for Medical Education.
In contrast, the step-up approach recently described by Molina-Infante et al. in the Journal of Allergy and Clinical Immunology (2018 Mar 6. doi: 10.1016/j.jaci.2018.02.028) consists of a two-food elimination diet escalated to a four- and six-food elimination diet as needed.
This diet, which the researchers described as a “2-4-6” approach, starts with elimination of milk and wheat, the two most common food triggers for eosinophilic esophagitis. If patients do not respond, eggs and soy/legumes are eliminated, and if that fails, nuts and seafood are eliminated.
Once patients do respond, foods are reintroduced one at a time over 6 weeks with repeat endoscopy and biopsy, according to the report.
Molina-Infante and coauthors further described results of the diet in 220 patients with eosinophilic esophagitis. Of that group, investigators said 90 patients refused dietary therapy.
However, for the remaining 130 patients, 74 responded to the diet, the investigators reported.
Of 74 responders, 56 (43%) achieved remission at the first step in which milk and wheat were eliminated, results show, while an additional 10 had remission after the step up to four-food elimination, and another 8 had remission after the final step up to six-food elimination.
Dr. Spechler said his current take on diet therapy for eosinophilic esophagitis would be to start with the two-food elimination diet.
That first step alone identified about three-quarters of the patients who eventually would respond to the step-up approach in the Molina-Infante study, he observed.
For patients who do not respond and are motivated to continue, Dr. Spechler said he would move up to the four-food elimination diet, which identified about 90% of patients who eventually responded.
However, Dr. Spechler said he would consider the final step-up only in “exceptionally highly motivated” patients, since that step seems to identify very few additional responders.
“They got very little benefit here from going all the way up to a six-food elimination diet,” Dr. Spechler said.
Patient acceptance may be one major barrier to any dietary approach to treatment of eosinophilic esophagitis, regardless of how intensive the approach is.
“Ninety patients just flat-out refused to try the diet, so this is not a popular form of therapy,” Dr. Spechler noted.
However, diet is one of three valid treatment options for patients who do have an established diagnosis of eosinophilic esophagitis, the other two being proton pump inhibitors (PPIs) or 6-8 weeks of topical steroids, according to Dr. Spechler.
“If you’re going to use diet, I think you begin with that two-food elimination diet,“ he said. “Fortunately, most of the patients who don’t respond to diet will respond to PPIs or steroids.”
Dr. Spechler reported disclosures related to Ironwood Pharmaceuticals and Takeda Pharmaceuticals.
