Can environmental allergies (food, pollen, dust mites, contrast dye, penicillin) cause a high positive ANA?

I have seen this: While the +ANA is suggestive of SLE there can be other causes - other connective tissue disease, autoimmune thyroid disease, auto immune hepatitis to name some. I have seen a lot of people with + ANAs who only have as another problem a history of allergic reactions and I am convinced that thee allergic reactions can cause a + ANA. Everyone can have very low titters (amount) of ANA.
