Correlation Between Serum Uric Acid, Serum Homocysteine Level and Interleukin- 17 in Lupus Nephritis Patients
Systemic lupus erythematosus (SLE) is a chronic inflammatory multisystem autoimmune disease characterized by pathogenic autoantibodies production against nuclear structures . SLE affecting mainly women of childbearing age and is characterized by unpredictable flares and remissions. Disease severity varied from a mild episodic disorder to a rapidly progressive life-threatening illness. The kidney is the most commonly involved visceral organ in SLE. Therefore, identifying new noninvasive biomarkers of LN severity and outcome is mandatory. IL-17 is a potent pro-infammatory cytokine that amplifes T-cell activation and stimulates fibroblast cells, endothelial, and epithelial cells to produce several pro-infammatory mediators, including IL-1β, IL-6, and TNF-α. IL-17 receptor signaling enhances the expression of multiple pro-infammatory mediators. Hence, IL-17 enhances the production of neutrophil-attracting chemokines
