Clinically often identified with lupus erythematosus.
Lupus erythematosus is an autoimmune disease with slow onset, insidious attack, diverse clinical manifestations, and a variety of autoimmune diseases involving many systems and organs. It produces a variety of autoantibodies due to cellular and humoral immune dysfunction. . It can affect the skin, serosa, joints, kidneys and central nervous system, and is characterized by autoimmunity. There are many autoantibodies in patients, which not only affects humoral immunity, but also affects cellular immunity, and the complement system also changes. The pathogenesis is mainly due to the formation of immune complexes. The exact cause is unknown. The condition is an alternating process of recurrent and remission. The disease is more common in young women. The prevalence rate in China is higher than in Western countries and may be related to genetic factors.
