SLE and Lupus Nephritis is a chronic autoimmune disease characterized by the immune system mistakenly attacking healthy tissues throughout the body. One common and potentially severe manifestation of SLE is Lupus Nephritis, where the kidneys become inflamed, leading to various renal complications. Lupus Nephritis occurs when the immune system targets the kidneys, causing inflammation that can impair their function.
This condition significantly contributes to the morbidity and mortality associated with SLE, highlighting the importance of timely diagnosis and management to preserve renal function and improve overall outcomes for individuals affected by this complex autoimmune disorder.
Definition of SLE
Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease in which the immune system mistakenly attacks various tissues and organs in the body. This systemic autoimmune disorder can affect multiple systems, including the skin, joints, kidneys, heart, lungs, brain, and blood cells. SLE is characterized by a wide range of symptoms that can vary in severity, such as joint pain, skin rashes, fatigue, and inflammation.
The exact cause of SLE is not fully understood, but it is believed to involve a combination of genetic, environmental, and hormonal factors. Diagnosing SLE can be challenging due to its diverse symptoms, and treatment typically involves managing symptoms and preventing flare-ups through medications and lifestyle adjustments.
Symptoms of SLE
The symptoms of Systemic Lupus Erythematosus (SLE) can vary widely among individuals and may come and go. Here are common symptoms associated with SLE, presented in bullet points:
- Joint pain and swelling
