@Ty:

What do you think of this cover?

www.bedbugsupply.com/Bed-Bug-Mattress-Covers.html

I don't really like it (too hot). But I could try your suggestion of sleeping on it for 3-5 days.....

Hi buttercupbetty,

I had forgotten about that. Do you think it's important to know whether or not I have a (serologically) diagnosable Type 1 latex allergy? As opposed to going on my symptoms?


Based on your symptoms and description it appears to me (a layman) that it's more likely that you would be type IV but of course type 1 can be much more serious so it certainly can't hurt. If you have any doubts I would personally get tested on the assumption that it's better safe than sorry. They often do both tests together with the blood test first just in case it's a type 1 allergy which could lead to a reaction with the skin test series.

I don't really like it (too hot). But I could try your suggestion of sleeping on it for 3-5 days.....


I'm not Ty of course but this cover is a "membrane" type which has a pore size of 0 microns so no particles would get through it. There is a little more about allergy encasements and pore sizes in post #2 here .

The membranes wouldn't protect against any offgassing (they are vapor permeable) and to protect against this you would need a clear polyethylene plastic cover in the range of 5 mil or thicker (clear polyethylene is non toxic) but in your case it's the particles that are probably most important and as Ty mentioned the polyethylene would not be breathable at all and would likely cause temperature regulation issues as well as trapping any moisture in the mattress.

@Phoenix:

I left a message for my doctor. I will request the blood test. Since I have reacted to latex products (like gloves, bandaids, etc.) for 25 years, does it seem necessary to perform a skin test also?

Just trying to be conservative here ;) I'll do some more reading. Can a Type IV allergy lead to a more serious Type I? I certainly wouldn't want to sensitize myself toward a more severe allergic response.

Thank you!

Hi buttercupbetty - I don't know enough to answer your questions, but I do know enough to think it's a good idea to consult your doc about the possible problem. Doc will probably have own ideas about what tests should be run.

I agree. My doctor stays very current on the medical literature and I'm sure he'll have a recommendation for me.

Hi buttercupbetty,

I was actually thinking of a completely impermeable plastic encasement. I would prefer that to a bedbug or dust mite encasement for allergy testing purposes. The reason is that as Phoenix pointed out, it could be chemicals that are causing the problem and chemicals can pass through dustmite encasements. With a completely impermeable plastic encasement no air is getting through. They are also cheaper than dust mite encasements.

The easiest way I know of to find this is to get a mattress bag. They are easily found online using the term “mattress bag”. They are used for moving and you can also get them at places like U-Haul and home depot. As Phoenix mentioned, make sure you get one that is thick enough so it won’t tear. I looked briefly and found ones that were 3mil thick

www.containerstore.com/shop/?productId=10031718

However, I could only find the 5 mils in bulk orders. Perhaps Phoenix knows where to get 5 mils.
Phoenix brings up an important point about trapping moisture inside the mattress. You might want to air out the mattress before you encase it. After you get the bag around the mattress make sure there are no loose areas with air in them. Then seal the open end with moving tape or duct tape. Be forewarned that sleeping on one will have drawbacks. They do not breathe at all (like sleeping on a waterbed – the old fashion bag of water without all the covering foam). I am not certain but it might make noise when you move which could be annoying. But for 3-5 days of testing it should be bearable.

Good luck,
Ty

Hmmm....are you saying that I need to get a 5mm bag? :dry:

I'm kinda confused. I like the price on this one:

If you want to eliminate all the possibilities then clear polyethylene would be the only thing I know of that would stop anything from escaping. The membrane type encasements would stop all particulates.

If you decided to go with the polyethylene ... if it was for the long term (such as someone that needed to sleep with the plastic to prevent offgassing or chemical leaching over a long period of time) then 5+ mil would probably be best and you can get a 6 mil wrap from here or from a building supply store such as home depot in sheets of 10' x 25' for about $25 and you would need to seal the edges. If it was only for a short term such as you are considering then a mattress bag that was 3 mil or so (which is about the thickest that is commonly available that I've seen) would probably be fine.

@Phoenix:

Doesn't it make sense to eliminate one variable at a time? As you said, if my mattress IS the issue, then it could be the latex particles OR the chemical additives. If I use the cover I currently own:

www.bedbugsupply.com/Bed-Bug-Mattress-Covers.html

it would block latex particles, right? It would NOT block VOCs, though. If this "test" doesn't work (and I still have symptoms), then we could buy a thicker, impermeable mattress bag.

However, if serology tests show a Type 1 latex allergy, then I'm guessing it's "game over" and we sell the bed. Do you agree? I don't think you're recommending that we sleep on impermeable vinyl for the long term, right?

**Personal update: I slept in our guest bed last night and was able to breathe through my nose. Which is great :cheer: Except that it is pointing my suspicion to my wonderfully comfortable latex mattress :angry:

Thanks again for all your help deciphering this, Phoenix & Ty. I realize that neither of you are doctors (as far as I know) and I certainly will follow medical advice as to how I proceed.

Hi buttercupbetty,

There is a good brief overview here about the three types of reactions that can be connected to latex.

As far as I'm aware ... irritant contact dermatitis (which comes from rubbing skin irritation and from moisture not to the actual chemicals in the latex or the latex itself) can sometimes lead to a type IV allergy (to the chemicals in the latex) particularly in atopic individuals (people who tend to develop allergies). Since neither irritant contact dermatitis or type IV allergies are to the latex itself neither one leads to a type I allergy. Many people with type I allergies however experienced Type IV symptoms as a precursor to the more typical symptoms because the dermatitis can compromise the skin and result in the latex proteins entering the body. This is why it's a good idea to rule out an actual latex allergy with type IV symptoms.

If the allergy is to the actual latex proteins (type I) ... then the symptoms can be progressive and any natural latex should be avoided in all forms (not just in mattresses). Synthetic latex doesn't contain the same proteins as natural rubber. In some very severe cases of type I allergy (as an example) people who eat in restaurants would be at risk if the food was prepared by staff who were wearing rubber gloves. This would be very rare.

The thing that would make me cautious in your case is that the symptoms are nasal. If you are inhaling particles and they are irritating the mucous membranes then it could be either the chemicals in the latex or the latex itself.

For now since it's most likely that particles are the issue (rather than any offgassing) and since you already own an encasement that won't permit particles to go through it that's where I would start to see if it makes a difference with your symptoms.

I would also think that the mattress cover would make a difference as well.

Overall though ... I would go with your doctor's advice and if I was experiencing nasal symptoms I would want to rule out an early stage type I allergy.
