AIDS Patient Care and STDs:"Initial treatment with plasma exchange resulted in resolution of these abnormalities. However, the discontinuation of plasma exchange resulted in the prompt recurrence of laboratory abnormalities diagnostic for TTP.

Patients were subsequently treated with 2–4 doses of weekly rituximab resulting in durable remission. These patients are now 21 and 9 months beyond rituximab treatment. Rituximab appears to be safe and effective in this setting."
