Dairy Allergy - 21 months

Hi Dr
My son aged 21 nonths went into anaphylactic shock at 11wk and then at 13 months due to dairy allergy (proven). At 11wk he was given the incorrect formula (lactose free) and at 13 months it was during a milk challenge.

Over the weekend we ran a milk challenge for him. They syringed 2.5ml into his mouth and he spat it out, causing it to run down his chin. Within minutes of that running down his chin, he can out in a red blotch/raised area where the milk has touched his skin. He is a tube fed baby and l messed 3 drops of the milk on his arm which also reacted.

However, he tolerated the milk well and by the end of the day we had given him a feed of 150ml FCM with no adverse reaction.

Yest he sucked on a bun with marg on it, which obviously contained milk solids as he came out in the red blotch almost immediately again.

My paed says i can go ahead and use milk products on him (he is currently on Similac Alimentum) and that l should try Pediasure as he is currently peg fed and needs the nutrients.

My question is this - is he then still allergic if he gets such a reaction to milk? Will the reaction get less in time as he is exposed to more dairy?

Do i need to give him something when this happens? He was touching his face after the bun, so i dont know if he was sore or it was burning?

Should I keep him on the Similac or should I use the pediasure?
Should I try Nan HA rather and how does it compare kj wise to normal nan or pediasure?

Is there any change of getting another anaphylatic reaction if he has done so well this weekend?

Thank you

In my opinion your baby is still highly allergic to cow's milk as reflected by the urticarial rash he developed on his chin and his reaction to the margarine with milk solids. He should definitely remain on the Similac Alimentum. Use a margarine which does not contain milk solids such as Cardin or Ole.Your son should have a skin prick test done to cow's milk and also a RAST test for cows milk. This will enable you to find out what is present allergy status is and whether he is above or below the cut off point values for safety and the likelihood of another anaphylactic episode. If you let me know what these values are I will be able to advise you further ie the size in millimetres of his skin test reaction and the actual result of his RAST test.Your son should be seen and followed up by a paediatric allergist.

Hi Doc,
My now 3 year old has been diagnosed with Asthma, allergies and Eczema, His eczema has not flared up for over a year now, he is on Singulair and seretide, asthavent(reliever).
I have a question when he was a baby he was allergic to alot of things namely shellfish, ground and tree nuts, eggs, cows milk, wheat and a whole more. His allergis reaction used to consist of the following: hives, skin redness and tiny pimples on the face, wheezing and blocking of the airways, severe coughing and vommiting, over the last year he has outgrown everything except tree nuts, eggs and cows milk or anything dairy. His reaction of at all nowadays seems to be very delayed(after about an hour) he will cough a bit complain of stomach pain and then just vomit. No need to Allergex, pumps, wiping down with cool water, no eczema or wheezing. Is this a sign that he will outgrow this as sometimes i am so confused as he will eat yogurt or cheese and nothing will happen to him and sometimes he will throw up.The wierd thing also is he can eat biscuits and cakes that contain eggs but if he eats like scrammbled eggs he has an allergy towards it. I have also no noticed that his teeth is getting rotten, i think this is due to hm not gettig enough calcium in his diet, i have put him on Soya products shoudl i give him him a supplement for the lack of calcium please advise.
