They’ve changed the description of Angioedema causes as:
Mast-cell induced
Bradykinin induced
#AAISO
Was previously called histamine-induced but many other mediators are released from mast cells.
Another interesting concept: subcutaneous immunotherapy produces a better blood responses c/w with tolerance and sublingual produces better mucosal responses #AAISO Could they be combined in refractory cases? Never tried it myself…
I’m at #AAISO Ontario Allergy Update. An interesting point about patients with CSU (chronic spontaneous urticaria) is that they are more likely to have allergic diseases such as: allergic rhinitis and asthma than the general population.
Allergies don’t cause the urticaria but auto-IgE does so they have elevated serum IgE levels for both reasons. It’s mistaken by health professionals that the urticaria is therefore caused by allergy #AAISO

Food insecurity in the last 3-4 years is 3 X more likely to occur in families with food allergies in Canada #CSACI22
Food allergy labels that are quite expansive (ie everything seems to have a warning now) can drive families to have to purchase more expensive options #CSACI22
Families where children have food allergies during the pandemic were spending an increase of between $100-200 per month on food in Canada #csaci22 This is on top of their other previous costs
The POISED OIT study showed a much higher dropout in Adults vs Children
> 30% of adults vs 9% of children #csaci22
