I AM NOT A DOCTOR OR OTHER HEALTHCARE PROFESSIONAL
I looked into oral immunotherapy for tree nut allergies. There's a paper from 2022: https://onlinelibrary.wiley.com/doi/10.1111/all.15212 https://onlinelibrary.wiley.com/doi/10.1111/all.15212
They did it in a few stages:
1. First three days: test the child with increasing amounts of cashew protein, until the child has a reaction. Use the amount ingested for that reaction, to determine the single highest tolerated dose (SHTD = the maximal amount of cashew protein each patient could tolerate).
2. Next 24 days: the child ingests the SHTD daily.
3. After that: every month, the dose was increased (I think at an in-person visit), and taken at home for the next 30 days.
For #1, I looked at the amounts of protein they gave the child. Table S2 (in one of the supporting documents) shows how much they gave on days 1, 2 and 3. Of course they stopped increasing once the child had a reaction. If you convert the amounts of protein into equivalent numbers of whole cashews, then you get:
- day 1: start with 1/1800th of a small cashew, increasing up to a fifth of a small cashew.
- day 2: 1/5th small cashew, up to 2 small cashews
- day 3: 2 small cashews, up to 22 small cashews
22 small cashews is about equivalent to what they want to achieve by the end of the therapy, i.e. if you don't have a reaction after eating that many, you won't have a reaction to a greater quantity.
It seems a bit hard to DIY it, because:
- The first three days requires very small amounts of cashew protein. At home we don't have either (i) isolated cashew protein, or (ii) tools to measure such small amounts (starting with 0.1mg cashew protein, or 0.5mg cashew).
- For the first three days, we'd need to be very vigilant to watch out for a reaction. I don't know whether, in a supervised setting, they'd observe or measure other factors than just an apparent reaction, to make sure the procedure is safe.

- spike021 2y agoFor curiosity sake, curious if the tree nut allergy here was typical reactions (hives, nose, etc.)? I have a tree nut "allergy" but doctors always call it more of a "hypersensitivity" because my reactions are usually involving terrible stomach cramps and pain accompanied occasionally by swollen throat (more so for almonds than cashews). I've wondered if it's worth trying to do this myself.
- sbelskie 2y agoSounds like Oral Allergy Syndrome. I also have it with almonds and stone fruits.
- 2muchcoffeeman 2y agoWhy wouldn’t you see the doctor? Cost? Not covered by insurance?
- spike021 2y agoI have in the past but they weren't much of a help. Allergy scratch test results didn't correlate at all. They referred me to a throat doctor to make sure it wasn't anything in my digestive system. So ended up doing an endoscopy. No notable findings there either. So never been given any kind of ideas of things to try other than keeping a food journal, which has been useless to me.
- ekianjo 2y agofor allergies most doctors are utterly useless. they either dont know the topic or the tests are unreliable and in the end you come out with no more info than you came in.
- rahimnathwani 2y agoSudden loss of appetite, followed soon by nausea, and then vomiting.
- fsckboy 2y ago>day 1: start with 1/1800th of a small cashew, increasing up to a fifth of a small cashew do you mean, if there is no reaction to 1/1800th within minutes(?) then try 1/900th, lather rinse repeat?
- rahimnathwani 2y agoCorrect. The specifics are in the second page of this doc: https://onlinelibrary.wiley.com/action/downloadSupplement?doi=10.1111%2Fall.15212&file=all15212-sup-0002-TableS1-S4.docx https://onlinelibrary.wiley.com/action/downloadSupplement?do... The intervals start at 10 minutes (start of day 1) and go to 90 minutes (start of day 3). The dosage increments (in mg of cashew protein) start at 5x, but are mostly 1.5x or 2x.
- WhitneyLand 2y agoOk I’ll bite - Wouldn’t have guessed it necessary to bookend a comment with all caps disclaimers, yet it’s happening, so I’m going to guess you have an interesting or cautionary anecdote around it we can possibly learn from?
- rahimnathwani 2y agoNope. Just being cautious!
- gotoeleven 2y agoSince you seem to be either a doctor or some other kind of healthcare professional can I ask what would you prescribe for aching butt?
- newaccount74 2y agoCortisone
