OIT and EoE: What’s the Real Story? 🤔💭
It’s one of the most common questions in allergy care — “Can patients with EoE (eosinophilic esophagitis) safely do Oral Immunotherapy?”

Dr. Chacko, Dr. Farah Khan, and Dr. Doug Jones sat down to break it down 👇

💡 It’s not a hard “no.” For many years, EoE was considered an absolute contraindication for OIT — but real-world experience tells a different story. With careful monitoring and individualized plans, many patients with mild or controlled EoE can safely undergo OIT.

⏳ It might just take longer. OIT for EoE patients often means slower dose increases and close observation, but the benefits can still be life-changing.

👩‍⚕️ Meet families where they are. There’s no single “right” answer — every patient’s journey looks different, and treatment should evolve with their needs.

And fun fact — these collaborations aren’t just happening in clinics.
As Dr. Chacko says:
“Sometimes, allergists aren’t learning this in training — they’re learning it here, from each other.” 💬

A parent messaged me about their 18-month-old daughter who recently did a walnut challenge. Her numbers weren’t that high, but she reacted on the fourth dose. Their allergist suggested OIT, and they wanted to know what options exist for cases like this, and whether “modified OIT” is real. 🌰👶

This is actually a great case. Yes—modified OIT is absolutely an option. We use it all the time. Many kids tolerate low doses and react only when the dose gets higher. Instead of stopping completely, we simply drop the dose, keep a small amount in the body, and slowly build up from there.

A failed challenge doesn’t mean failure—it just tells us where to start. Modified, fast, or accelerated OIT all help us keep the food in the system safely, move forward without losing momentum, and still build tolerance over time.

So their allergist is doing a great job, and this is a very reasonable plan for walnut.
These are the cases where modified OIT shines. 💛

Second Opinions Save Futures 🥜💛
This baby was told to avoid peanut completely after a questionable allergy result. Thankfully, Mom had a friend in the allergy field who said, “Get a second opinion.”

She found us — and we introduced Bamba puffs and a peanut challenge.
Now? No allergy. 🙌

Sometimes the difference between lifelong avoidance and freedom is simply asking again.

If something feels off, always get a second opinion — it can truly change your child’s path.

Taking you back to the first Friday of December 🎄🥜
Because the progress these little ones are making deserves the spotlight.

✨ Landon is almost 1 year old and already tolerating 300 mg of peanut flour with low labs. At this pace, by the time he’s 2 or 3, I fully expect him to be eating peanut butter without worry. That’s the power of starting early.

✨ Brady has a mild cashew allergy — numbers around 1.5 — and we’ve already begun tiny cashew doses. By ages 4–5, he’ll likely be eating cashew regularly. Slow, steady, safe wins every time.

✨ And this sweet 16-month-old who traveled six hours from North Carolina — allergic to cashew and sesame, seen previously but never offered treatment. Her cashew IgE dropped from ~7 down to ~2–3 when we repeated it today. She’s still allergic, but that lower number lets us move a little faster on cashew OIT and once we get her to a safe cashew dose, we’ll tackle sesame next.

Across all three cases, the theme is the same: starting young, personalizing the plan, and building real protection for everyday life.

If this sounds like your child — or a family you know — we’re here to help.
And if you’re not local, I’ll still guide you to someone who can get you on the right path.
Happy Friday 💙

Sharing Penelope’s journey today — a reminder that even the trickiest egg allergy cases can turn around with time, patience, and the right plan 💛👨🏾‍⚕️

• Penelope used to vomit with even the tiniest bit of egg 😢
• When I saw her in 2023, she reacted to baked egg — not even visible egg 😳
• Her IgE was 22, and now it’s 2 📉🙌
• She takes 10 mL of egg white every night at home — calmly and easily 🥄✨
• After a slow journey and a few setbacks, she’s now cleared to eat scrambled egg 🍳💪
• No Xolair, no extra meds — just gradual, guided OIT at her pace 🌱

Penelope’s officially lost a huge amount of sensitivity — and now her favorite egg treat?
🍩 “Little donuts” — I approve!

Egg OIT is one of the trickier ones, which is why only a few clinics in the Southeast offer it. But with the right guidance, kids can absolutely succeed.
If your child has egg or milk allergies, we’re happy to help — and if it’s not us, we’ll point you to someone who can 👨🏾‍⚕️🤝

Back From the Orlando College Meeting ☀️🧪
A brilliant scientist asked me this week:
“Tom, if food OIT is so effective, why isn’t every allergist doing it?”

Truth is — we all agree OIT should be happening.
The issue is training.
Most programs don’t teach how to:
• dose milk/egg safely
• up-dose correctly
• manage high numbers
• choose free-eat vs low-dose maintenance

It’s not reluctance — it’s lack of guidance. And families shouldn’t have to wait 10 years for the system to catch up.

If you’re an allergist or fellow wanting hands-on OIT experience, drop your city in the comments. I’m gauging interest for possible training opportunities.

Allergies, Love & Peanut Butter Kisses 💋🥜
During a clinic visit, Dr. Doug Jones shared a story that every allergist — and every family managing food allergies — can relate to.

An adult OIT patient asked:
“When can my partner have peanut butter in the house again?”

While discussing safe timing and exposure, Dr. Jones added something many forget to think about 👇
💋 Kissing counts too. Even small traces of peanut butter can transfer through saliva, so brushing, rinsing, and waiting a few hours helps keep things safe.
💡 It’s not just the patient—it’s their environment. OIT helps reduce anxiety, but awareness around social and relational exposure still matters.
❤️ The goal: normal life, safely lived. Because food allergies shouldn’t get in the way of connection—or love.

💭 Why aren’t more allergists treating babies early — when prevention can change everything?

In this conversation, Dr. Chacko and Meenal Lele, founder of Lil Mixins, get real about why early allergen introduction and food-based prevention still aren’t the norm:
⚕️ Many allergists stick to the same models they’ve practiced for decades — change in medicine takes time.
💰 There’s little financial incentive for natural, food-based care. You don’t make money on peanuts.
🏛️ Pharma-backed systems naturally prioritize FDA-approved drugs and studies, even when food works.

It’s not about bad intentions — it’s about bias. And that bias can keep parents from hearing about options that actually help prevent food allergies before they start.

✨ Knowledge is power. Start learning. Start asking questions. Start early.

Jace’s Military Journey 🇺🇸✨

➡️ The Patient Story
Jace has been with us since he was a young boy — 5th and 7th grade — managing a peanut allergy that once limited his future.

➡️ The Progress
Today, he safely eats 2 tablespoons of peanut butter, the same dose he takes each day at home.
We filmed his dose so his recruiter can see proof for his military application.

➡️ The Treatment Impact
Peanut OIT transformed his daily routine.
His “medicine” now? A peanut butter & jelly sandwich — safely, confidently, every day.

➡️ Why This One Is Special
Watching patients grow up, beat allergies, and step into adulthood dreams is one of the most rewarding parts of this work.

Takeaway:
➡️ Peanut treatment can open doors — even to the military.

From 83 ➡️ Hope for the Future 🥜✨
This 9-month-old came in with a peanut IgE of 83 — and most people think that’s “too high” to treat. But doing nothing means there’s an 80% chance it’ll rise even higher as they grow older.

That’s why the early window (6 months – 3 years) is so powerful. With careful OIT, even infants with high numbers can build tolerance over time. 💪

Avoidance isn’t the only answer — awareness and early action make all the difference.

Tom Chacko here — and this is a powerful reminder of how serious cashew allergies can be, but also how much progress is possible.

We’re keeping Harrison offline today, but his mom shared his story:
• One day he took a small bite of a Larabar — and had a severe, unexpected cashew reaction
• He became anaphylactic: unconscious, vomiting, rushed to the ER 🚑
• Mom literally carried him in, unconscious — terrifying for any parent 💔

Fast-forward to today:
• Harrison is finishing cashew OIT with me
• He just ate 1 gram of cashew powder — basically one whole cashew 🌰👏
• They trusted me because they’d already completed peanut successfully
• With careful microdosing, we protected him and rebuilt tolerance over time
• By age 5–6, he’ll likely be eating cashews completely normally 🙌

Cashew reactions can be very scary — but early, guided treatment changes everything.

If your child has had a reaction to cashew or any nut:
✔️ There are options
✔️ We can protect from accidents
✔️ And in many cases, reverse the allergy over time

You don’t have to navigate this alone. ❤️‍🩹

The Skin vs. Mouth Debate — And Why It Matters 🥜👶
In this clip, Dr. Gideon Lack breaks down one of the biggest insights in allergy science: how babies become allergic — and how to prevent it.

⛔️ Always consult your Allergist for individualized treatments - this is not medical advice, for education only.

Here’s the key idea behind the Dual Allergen Exposure Hypothesis:

✨ Eczema skin + environmental peanut = higher allergy risk.
If a baby has eczema or a weakened skin barrier, peanut proteins in the home can enter through the skin and trigger an IgE allergic response — especially if the baby isn’t eating peanut yet.

✨ Oral introduction early = tolerance.
Feeding allergens early (3–4 months onward in baby-safe forms) teaches the immune system, “This is safe.”
This process is called oral tolerance induction — the foundation of allergy prevention.

✨ For eczema babies, don’t wait.
If a household eats peanut regularly, but the baby isn’t eating it orally, risk goes up.
Introduce early → risk goes down.

This science is one of the major reasons early allergen introduction is now standard guidance — and why prevention is possible.

👉 Stay tuned for more groundbreaking insights from Dr. Chacko & Dr. Gideon Lack as they reshape the future of allergy care.
