Concomitant sickle cell disease and systemic lupus erythematosus: A single-center case series.

Sickle cell disease (SCD) and systemic lupus erythematosus (SLE) are two uncommon disorders each characterized by multisystemic manifestations. Individuals with SCD exhibit abnormalities in the complement pathway, which may predispose patients to develop autoimmune disorders such as SLE. As many manifestations of SLE mimic those of SCD, diagnosis and therapeutic management of SLE in a patient with known SCD may be delayed.
