Suggest Treatment For Peanut Allergy
Question: Peanut allergy question:
Our 7 year old son had an allergy panel done on his blood recently and we want to confirm whether the test shows he is at high risk for anaphylactic shock or not from peanuts. I will attach a copy of his test results.
Since a scratch test which showed a strong reaction to peanuts, we have been carrying epipens and concerned with anaphylactic shock. Days before the first scrach test our son had eaten peanuts and had a slight rash around his mouth - but they were salty peanuts (on the airplane) and the salt may also have caused it. He had also drank peanut butter smoothies before once or twice and had no reaction. My wife and I ate a lot of peanut butter when he was young (and a little when my wife was nursing), but never directly had him eat it.
His recent blood test showed ARA H2 was high and ARA H1 too. But ARA H3,H8,H9 were low. With H2 I understand this means he has the peanut allergy. And it is a strong one. And with H1 high too the risk of analphylactic shock is high enough to warrant the epipen. But wanted to confirm this understanding AND also when the low ARA H3 and H9 is considered. Could you please share your interpretation?
With this result, is there any treatment we should consider to desensitize him to peanuts - like the new patch or other?
Thank you and best regards, XXXX

Brief Answer:
He is mostly having allergy to peanuts.
Detailed Answer:
Thanks for your question on Health Care Magic.
I can understand your concern.
Peanut allergy is not that common but can be seen frequently.
It is measured by peanut specific IgE levels.
And antigens (allergens) used in this are AHA 1,2,3.
These are most commonly used.
Amongst these three, AHA 2 is more specific.
If this is raised then he is definitely having peanut allergy.
And honestly speaking, there is no 100% cure (proven) for peanut allergy.
Some research says that oral immunotherapy with incremental doses of peanut containing food between the age of 4-11 years is beneficial.
But it is not proven.
No patch or injections are available. Only oral immunotherapy is available.
Hope I have solved your query.
I will be happy to help you further.
Wish you good health. Thanks.

Thank you Doctor. Were you able to see his test results?
With AHA 2 over 9 and AHA 1 over 1, but very low AHA 3, does this still mean that he might run risks as noted above?
Why AHA 2 and 1 are high, but 3 is so low?

Brief Answer:
He is mostly having allergy to peanuts.
Detailed Answer:
Thanks for your follow up question on HCM.
Now I have received the report.
He is having allergy to peanuts.
All these are allergens of peanuts.
So it is not necessary to have all these positive.
In trials, AHA 2 positivity is very common, followed by AHA 1.
He is having both positive, so peanut allergy is likely in his case.
If AHA 3 is negative, it does not rule out peanut allergy.
So in my opinion, he is having peanut allergy despite of negative AHA 3.
Hope I have solved your query.
