What effect does systemic lupus erythematosus have on the renal system?

• A. It causes congenital kidney defects
• B. It leads to nephritis
• C. It results in kidney stones
• D. It causes chronic urinary tract infections

Answer: (B)

Systemic lupus erythematosus (SLE) can significantly impact the renal system, primarily through a condition known as lupus nephritis. This is an inflammation of the kidneys that occurs when the immune system mistakenly attacks the renal tissues. The inflammation can impair kidney function, leading to symptoms such as proteinuria, hematuria, and even elevated blood pressure. Lupus nephritis is a serious complication of SLE and often requires careful monitoring and management. Early detection and intervention are critical to prevent long-term kidney damage and potential kidney failure, making it a key area of concern in patients with lupus. Other options, while related to kidney health, do not accurately represent the direct effects of systemic lupus erythematosus on the renal system as specific to the disease process. Congenital kidney defects typically arise from genetic or developmental issues rather than autoimmune disorders like SLE. Kidney stones can occur due to a variety of factors, including dietary habits and hydration levels, but are not a direct consequence of lupus. Chronic urinary tract infections may be seen in some patients, yet they are not specifically driven by lupus and are more often related to structural anomalies or other infections rather than the autoimmune pathology of the disease.
