Are systemic lupus erythematosus patients carrying MEFV gene less prone to renal involvement? Report of three cases and review of the literature.

Familial Mediterranean fever (FMF) is an autosomal recessive auto inflammatory disease, characterized by acute attacks of serositis, arthritis or skin rash. Systemic lupus erythematosus (SLE) is a chronic, autoimmune disease characterized by multisystem inflammatory lesions affecting any organ systems in the body. Coexistence of FMF and SLE is rare in literature. In this report, we present three patients with FMF associated with SLE.
