Lupus nephritis is a kidney disorder that is a complication of systemic lupus erythematosus (SLE), an autoimmune disease. In lupus nephritis, the body's immune system mistakenly attacks the kidneys, causing inflammation and damage to the kidney tissues. This can lead to symptoms such as blood in the urine, proteinuria, high blood pressure, and reduced kidney function. Research in lupus nephritis focuses on understanding the underlying mechanisms of the disease, developing better diagnostic tools, and finding more effective treatments. This includes studying the role of immune cells and inflammatory cytokines in kidney damage, identifying biomarkers for early detection of disease progression, and testing new therapies such as immunosuppressive drugs or biologic agents. Overall, the goal of research in lupus nephritis is to improve outcomes for patients with this debilitating condition.
