Systemic Lupus Erythematosus
Systemic lupus erythematosus (SLE) is an autoimmune disease that can affect multiple organs in changing combinations. No single symptom or positive antibody test confirms active lupus by itself.
Key points
- Joint pain, photosensitive rash, mouth ulcers, blood-count changes and fatigue can occur, while kidney or neurological disease may be less obvious.
- Diagnosis and activity assessment combine symptoms, examination, urine, blood tests and exclusion of infection or other causes.
- Treatment intensity follows organ involvement; immune suppression can control disease but raises infection and monitoring risks.
Catalogue matches do not diagnose SLE or indicate a safe antimalarial or immunosuppressant plan.
What determines whether a flare is serious?
Skin or joint symptoms differ in urgency from kidney inflammation, chest-lining disease, blood-cell destruction or neurological involvement. Infection can resemble a flare, especially during immune-suppressing treatment, so increasing medicine without assessment can be unsafe.
How do medicines fit into long-term care?
Hydroxychloroquine has broad long-term roles for many patients and requires dose and eye-safety review. Azathioprine has selected organ and pregnancy-related uses with blood and liver monitoring. See autoimmune support.
When to seek urgent care
Seek urgent care for chest pain, severe breathlessness, new confusion, seizure, weakness, reduced urine, heavy bleeding or high fever during immune-suppressing treatment.
