Fucking Kiwi Fruit

Apparently, I have a severe allergy to Kiwi Fruit. A year ago I noticed that I reacted after eating one by getting sick, so I generally avoided it. Yesterday however, I had forgotten, and made Sasha a smoothie with kiwi in it. She had me take a  taste, and I thought nothing of it.

Bad Mistake.

As my throat began to close, my first thought was to where I put my allergy medicine, which helped control things, but it ended up feeling like the worst hay fever attack ever after that. Dizzy, sore throat, eyes watering, the works. Fortunately, I didn’t eat much, as apparently it could get a lot worse.

From the medical site:

Adverse Reactions:

IGE AND IMMUNE:
Diarrhoea, vomiting, and abdominal pain. Burning of lips and mouth. Pruritis of the eyes, ears, tongue, pharynx, mouth. Angioedema. Dermatitis and atopic dermatitis. Respiratory complaints. Pharyngeal swelling. Colic.
A 26 year-old patient with a localized pruritic reaction a few minutes after eating kiwi fruit, repeated a few months later, accompanied by dysphagia, vomiting and urticaria. (Garcia1989 ref. 536 34)
In 22 patients allergic to kiwi fruit, 10 with severe systemic reactions and 12 with localized symptoms confined to oral and pharyngeal mucosa (oral allergy syndrome), prick tests showed positive reactions to kiwi fruit in all patients, whereas specific IgE to kiwi fruit could be demonstrated only in patients with generalized severe symptoms. Surprisingly, all 22 patients with clinical kiwi allergy showed positive prick test results and elevated IgE to birch pollen. Clinically, all complained of rhinitis during birch pollen season. Many patients showed sensitization to grass and mugwort pollen. Also, food allergy was found to be associated with kiwi allergy: we found strong reactions to apple and hazelnut; moderate reactions to carrot, potato, and avocado; and weak reactions to wheat and rye flour, pineapple and papaya, and their enzymes bromelain and papain. RAST inhibition studies revealed cross-reacting antigens between birch pollen and kiwi fruit. Interestingly, patients with birch pollen allergy without clinical signs of kiwi allergy had positive prick test reactions to kiwi. Patients with kiwi allergy showed higher concentrations to birch pollen IgE compared with patients with isolated birch pollen allergy. (Gall 1994 ref.535 34

  1. I googled "birch tree distribution graph" and hit this page USGR Page. It seems to be more focused on the current distribution on the east coast but there was a graphic that showed "Current Distribution of Forests in the United States".  Looking at that graph I\’d say you want to be careful about what time of year you go to Disneyland but you probably wouldn\’t visit the other states where the purple aspen-birch are.  Besides if I understand this part I clipped from the page given the impacts of continued CO2 and other emmisions you won\’t have to worry about birch for long.
    "The effects of climate change on the rate and magnitude of disturbance (forest damage and destruction associated with fires, storms, droughts and pest outbreaks) will be an important factor in determining whether transitions from one forest type to another will be gradual or abrupt. If disturbances in New England, for example, do not increase, there is a possibility of a smooth transition from the present maple, beech, and birch tree species to oak and hickory. Where disturbances increase, transitions are very likely to be abrupt."

  2. I should have waited to post.  I did the next obvious queries; "birch pollen disneyland" and hit this Photo Blog" who\’s author I can\’t identify but he seems to be under the impression that high wind on April 1st last year created a high concentration of birch pollen. I guess I\’d feel better if the tag date wasn\’t April 1st and I knew who "omTom Go510" was.  AmyJ has a blog entry for Mar 9, 2008 that descibes her son\’s reaction to high birch pollen conentration and has gone to Disneyland. But she and her son were living in Switzerland when he had the interaction.  Bummer I guess spring in Switzerland is off the bucket list.  There are a lot of results to these queries these days.
     
    Looks to me like you want to be careful about where you travel between the last part of March and the first part of May.  Oh, for convenience lets say from easter to labor day here in the US.  Or from the spring equinox till the first full moon after in Aires if you like to track your calendar that way.  And probably by 2028 won\’t have to worry about birch trees at all.
     
    I guess I\’ll have to give up on the idea of making a hazelnut apple crisp now too, even though it sounds pretty good on ice cream with a carmel drizzle when you think about it.
