Not a stupid question at all. It can get very confusing. SLE stands for Systemic Lupus Erythmatosus (not sure of the spelling on the last word). It's usually easier just to refer to it as "lupus" than saying that mouthful. BUT there are different kinds of lupus, like discoid, systemic, nephritis. Saysusie can probably give you more info on the different types but in answer to your question, yes it's the same.
