Overview
Systemic lupus erythematosus is a chronic autoimmune disease that can affect joints, skin, kidneys, lungs, heart, blood cells, and the nervous system, often with changing periods of activity and remission.
What current evidence indicates
- No single test diagnoses lupus. Clinicians combine symptoms, examination, blood and urine studies, and sometimes tissue biopsy.
- Treatment is tailored to the organs involved, so monitoring and follow-up depend on which systems are affected and aims to control symptoms and flares, minimize disease activity, and prevent irreversible damage.
- Current research includes genetics, biomarkers that may predict flares or treatment response, immune mechanisms, and therapies designed to reduce organ damage.
What remains uncertain
A positive ANA alone does not establish lupus, and symptoms overlap with many other illnesses. Benefits and risks differ among anti-inflammatory, antimalarial, immunosuppressive, and biologic treatments.
Useful details for a clinical visit
- Past and current symptoms, including those that come and go
- Rashes, joint symptoms, chest pain, neurologic symptoms, and family history
- Medication list and blood pressure, blood, and urine monitoring
