Immunologists: If you have an autoimmune disorder, are you more resistent against normal infections?

So my (admittedly trivial) understand of autoimmune disorders is that your immune system, for one reason or another, becomes over-active and starts attacking your own body's cells, having mistaken them for a foreign body.

This got me thinking about a couple major questions:

1. If you were to occupy your immune system with pathogens of another kind, would that relieve the symptoms of the disorder?
2. Would you be more resistent to "standard" pathogens?

tl;dr If you have lupus: does that make you wolverine?
