Cytokines and systemic lupus erythematosus
SLE is an autoimmune rheumatic disease that principally affects women in the childbearing years.1 The prevalence of SLE varies between ethnic groups, being approximately 1:250 among black women, 1:1000 in Chinese women and 1:4300 in white women. SLE affects the joints, skin and blood in over 80% of patients and the kidneys, central nervous system and cardiopulmonary system in 30%–50% of patients. Between 10% and 30% of patients have anticardiolipin antibodies that are associated with arterial and venous thrombosis. The majority of patients demonstrate systemic manifestations, which may include fatigue, malaise, fever, anorexia, nausea and weight loss.
Many cytokines have been implicated in regulating disease activity and in the involvement of different organs in patients with SLE. This article reviews both the role of individual cytokines and discusses possible mechanisms of cytokine action in individual organs.
