What is lupus?
Systemic lupus erythematosus (SLE), usually called lupus, is an autoimmune illness in which inflammation can affect tissues such as the joints, skin, kidneys and blood cells. The symptoms and severity vary widely among individuals.
Lupus is one of several autoimmune disorders that senior rheumatologists evaluate. No single symptom or blood result is a complete diagnosis.
Possible symptoms and findings
- Painful or swollen joints and fatigue.
- Rashes or increased skin sensitivity to sunlight.
- Mouth ulcers, unexplained fever or hair changes.
- Symptoms involving kidneys, chest or other organs in some cases.
These symptoms are not specific to lupus and can occur for many other reasons.
Understanding ANA and further tests
An antinuclear antibody (ANA) test may be considered when lupus is suspected. ANA positivity by itself does not prove lupus; positive results occur in some people without the disease.
Doctors combine symptoms, examination and selected tests, which may include blood counts, kidney function, urine tests and more specific antibodies when appropriate.
Medical care and monitoring
Treatment is tailored to the affected organs, severity and overall health. A senior rheumatologist may prescribe medicines that manage inflammation or influence immune activity, and monitor for disease activity and side effects.
Additional specialists may be involved when organs such as kidneys or lungs are affected. Never start or stop a prescription treatment solely on the basis of online information.
Severe chest pain, trouble breathing, seizures, confusion or sudden significant swelling require immediate medical attention.
Frequently asked questions
Does a positive ANA always mean lupus?
No. A positive ANA alone is not a diagnosis.
Can lupus involve organs besides the joints?
Yes. Lupus may affect the skin, kidneys, blood and other organs.
Is regular follow-up important?
Monitoring can be important, depending on the disease and treatment.
