This guideline was developed through a collaboration between AGA and the Joint Task Force for Allergy-Immunology Practice Parameters, which comprises the American Academy of Allergy, Asthma & Immunology and the American College of Allergy, Asthma & Immunology. This guideline is jointly published in Gastroenterology and Annals of Allergy, Asthma and Immunology.

Predicting Response to Topical Steroids in Eosinophilic Esophagitis

A recent study (Wolf WA, et al. Clin Gastroenterol Hepatol 2015; 13: 45-58) examined 221 patients in a retrospective cohort study to determine how effective topical steroids were in the treatment of eosinophilic esophagitis (EoE).  The authors studied these patients from 2006-2013; the majority received budesonide (63%) and the remainder received fluticasone; the typical dosing was 0.5 mg-1 mg twice daily and 440-880 mcg twice daily, respectively. 129 (58%) of the participants were >18 years.

Key findings:

  • 57% had histologic response with <15 eos/hpf
  • Refractory patients “were difficult to treat with dietary and second-line pharmacologic therapies, with less than half responding even after multiple second-line therapies.” The most successful second-line approach was diet: 6 of 16 (38%) had improved histology (<15 eos/hpf).  Higher doses of topical agents were effective in 2 of 14 (14%) and alternative topical agent was effective in 2 of 7 patients (29%).
  • Dilatation at the time of disease presentation (25% of the study cohort) correlated with poor clinical outcome.  Only 40% (20 of 50) had a histologic response.
  • High tissue levels of tryptase and eotaxin-3 increased the likelihood of a steroid response.

As this was a retrospective study, there were several weaknesses.

Take-home message: The findings from this large cohort show that more than 40% of patients did not have a favorable histologic response.  Some recent studies indicate that higher doses of steroids may be effective, but this may be influenced by the proportion of individuals with advanced fibrostenotic disease.
