No FDA-approved treatments for #EoE Image
Treatment guidelines Image
40-50% of patients with #EoE respond to PPIs

PPIs can treat EoE in various non-acid suppressing mechanisms Image
PPIs should be used in #EoE Image
Fluticasone inhaler or budesonide swallow: the only STRONG recommendation in the guidelines for #EoE

No difference in efficacy between budesonide and fluticasone

About 61% histologic response ImageImageImage
Tips for using topical steroids in #EoE

(No need to wash out- oral candidiasis very rare here) Image
Keep your 👁 out for esophageal-specific steroids! Image
#Diet in #EoE

1. Most effective (>90%): elemental diet ($, hard to comply)

2.6⃣food elimination diet (72%): milk, egg, wheat, soy, nuts, and seafood

3. Target allergic therapy (46%)– not effective as IgE skin tests do not predict esophageal responses well Image
SFED Image
The more restrictive the diet, the better efficacy, but the lower likelihood of adherence

1 food elimination similar to 4 food!

Perhaps start with dairy +/- wheat, and then go from there!

Focus on what CAN be eaten. Partner with patient. Partner with RD. And allergist! ImageImage
SFED protocol. Lots of work...

Eliminate 6-8 weeks ▶️ endoscopy

If response, add food 6-8 weeks. If active disease on endoscopy, that food is trigger. Image
#EoE is a chronic condition, and needs maintenance therapy even when in remission.

Disease typically flares within 3 months Image
Untreated, #EoE transitions from inflammatory to fibrotic

If fibrosis, need to consider dilation Image

Dilation for #EoE

Note: dilation does NOT impact inflammation, so also need anti-inflammatory therapy ImageImage

Most inpatients require a bowel regimen. Our patients typically have most of the risk factors for #constipation!
#Constipation is more about symptoms than frequency! 🚽

It’s also a *symptom* (like chest pain), so need to figure out what’s causing it and treat accordingly.
