An autoimmune disease where the immune system attacks its own tissues, causing inflammation, pain, and damage to multiple organs.
Overview
Systemic Lupus Erythematosus (SLE, or simply lupus) is a chronic autoimmune disease in which the immune system mistakenly attacks healthy tissue throughout the body. It can affect the skin, joints, kidneys, heart, lungs, brain, and blood cells. Lupus is more common in women, particularly women of color, and typically develops between ages 15 and 44. The disease is characterized by flares (periods of increased disease activity) and remissions. Lupus is complex and variable — no two patients have exactly the same symptoms or disease course. While there is no cure, modern treatments have dramatically improved outcomes for most patients.
Common Symptoms
Symptoms vary widely and may include: • Joint pain and swelling • Extreme fatigue • Butterfly-shaped rash across the cheeks and nose • Skin rashes that worsen with sun exposure • Fever without infection • Chest pain • Hair loss • Mouth or nose sores • Kidney problems • Sensitivity to sunlight Symptoms can come and go, with flares triggered by stress, sun exposure, infections, or certain medications.
Diagnosis
Diagnosis involves: • Medical history and physical exam • Blood tests (ANA, anti-dsDNA, anti-Smith antibodies) • Urine tests (to check for kidney involvement) • Skin or kidney biopsy in some cases Lupus can be difficult to diagnose because symptoms mimic many other conditions and can change over time.
Current Treatments
Treatment is individualized and may include: • Anti-inflammatory medications (NSAIDs) • Antimalarial medications (hydroxychloroquine) — a cornerstone of lupus treatment • Corticosteroids for flares • Immunosuppressants (methotrexate, mycophenolate, azathioprine) • Biologic medications (belimumab) • Sun protection and trigger avoidance • Regular monitoring for organ involvement Treatment aims to control symptoms, prevent organ damage, and minimize flares.
Research Summary
Lupus research has advanced with the development of biologic therapies and better understanding of the immune mechanisms involved. Studies continue to explore genetic factors, environmental triggers, and more targeted treatments with fewer side effects. More research is needed, particularly on lupus in diverse populations and on treatments with fewer long-term side effects.
Community Resources
The lupus community is strong and supportive. Advocacy organizations provide education, connection, and research updates. Connecting with others who understand the unpredictable nature of lupus can be empowering. Explore our Stories page and community resources.
