Systemic Lupus Erythematosus: Symptoms, Causes & Treatment

Systemic lupus erythematosus is a chronic autoimmune disease, meaning the immune system that should protect the body mistakenly attacks its healthy tissues, causing inflammation that can affect the skin, joints, kidneys, heart, lungs, brain, and blood cells. It is called a systemic disease because it can affect more than one organ at once.

Lupus affects women far more than men, especially in childbearing age, and its severity varies greatly between patients. It is marked by a fluctuating course with periods of activity (flares) when symptoms intensify and periods of remission when they ease or disappear. Among its best-known signs are a butterfly-shaped facial rash, joint pain, and severe fatigue.

Although it is a chronic disease with no definitive cure yet, modern treatments have enabled most patients to control the disease and live a near-normal life. Treatment relies on calming the immune system, preventing flares, and protecting organs, with regular follow-up to detect any kidney or other organ involvement early. Early detection and adherence to treatment are the keys to avoiding complications.

• Severe fatigue and low fever.
• Joint pain and swelling.
• A butterfly-shaped facial rash and sun sensitivity.
• Hair loss and mouth ulcers.
• Symptoms by the affected organ (kidneys, heart, lung).

• A dysregulation of the immune system for reasons not fully understood.
• Genetic predisposition.
• Environmental triggers such as sun, some infections or medications, and hormonal changes.

• Female sex and childbearing age.
• A family history of autoimmune diseases.
• Sun exposure and certain medications.

• Clinical assessment of the multiple symptoms.
• Immune tests (antinuclear antibodies ANA and others).
• Blood and urine tests to assess kidney and blood-cell involvement.

Medications

• Anti-inflammatories and antimalarial drugs (hydroxychloroquine), which are a mainstay of treatment.
• Corticosteroids and immunosuppressants during flares or organ involvement.
• Modern biologic therapies in selected cases.

Lifestyle

• Sun protection, rest, stress management, and regular follow-up.
