Is Sculptra an option if you have a mild autoimmune disease?

I'd like to have 1-2 vials of Sculptra injected, but have a mild autoimmune disease (alopecia areata). It usually only causes 1 small coin-sized patch of hair loss when it flares up. I am otherwise healthy, but am concerned because Sculptra is contraindicated in patients with autoimmune disease. Is Sculptra contraindicated in ALL cases of autoimmune disease, or generally just the most severe? Would it likely cause disease flare-ups, or otherwise be harmful in my case?
