-
ESR/CRP elevation
-
CBC showing cytopenias
-
Antiphospholipid antibodies

False-positive RPR/VDRL for syphilis (important clinical clue)
SLE Classification Criteria (2019 EULAR/ACR)
A scoring system combining clinical and immunologic domains.
Diagnosis confirmed if:
-
ANA ≥1:80 AND
-
Total score ≥10 with at least one clinical criterion
Treatment of SLE
Management depends on disease severity.
General Measures for All Patients
-
Avoid UV exposure; use SPF ≥50 sunscreen
-
Quit smoking
-
Regular aerobic exercise
-
Routine monitoring for cardiovascular risks
-
Screen for latent TB before immunosuppression
These recommendations echo key points from the uploaded rheumatology lecture.
1. Mainstay Drug: Hydroxychloroquine
Hydroxychloroquine (HCQ) is the cornerstone therapy for nearly all SLE patients.
Benefits:
-
Reduces flares
-
Protects organs
-
Improves survival
-
Helps treat skin and joint symptoms
Long-term HCQ requires regular eye exams due to rare retinal toxicity.
2. Corticosteroids
Used for flare control and during acute organ involvement.
-
Mild: low-dose oral prednisone
-
Moderate: oral steroids + HCQ
-
Severe: IV methylprednisolone 250–1000 mg daily for 3 days
3. Immunosuppressive Agents
Used when major organs are involved or HCQ is insufficient:
-
Mycophenolate mofetil
-
Cyclophosphamide
-
Methotrexate
-
Azathioprine
These suppress immune overactivity and protect tissues.
4. Biologic Therapies
Newer treatments include:
-
Belimumab (anti-BAFF)
-
Rituximab (anti-CD20)
These monoclonal antibodies target specific immune pathways.
5. Treatment of Lupus Nephritis
Combination therapy:
-
IV steroids
-
Mycophenolate or cyclophosphamide
Followed by maintenance therapy with lower doses.
6. Management of Neonatal Lupus
Anti-Ro and anti-La antibodies can cross the placenta, causing congenital heart block.
Infants may require early monitoring or pacemaker placement.
Conclusion (Simple Language)
SLE is a long-term autoimmune disease where the immune system becomes confused and attacks the body. It can affect the skin, joints, kidneys, heart, lungs, blood, and brain. Some people experience occasional flares, while others have constant symptoms.
Although there is no cure yet, modern treatments—especially hydroxychloroquine, steroids, and immunosuppressive drugs—make SLE much more manageable. With the right medical care, lifestyle changes, and early detection, most people with lupus can live long, active, and productive lives.
What You Should Do
✔ Use sunscreen SPF 50+ every day

✔ Avoid smoking
✔ Follow up routinely with a rheumatologist
What You Should Avoid
✘ Avoid excessive sunlight

✘ Do not ignore symptoms like swelling, chest pain, or confusion
✘ Avoid herbal supplements without medical supervision
Summary
Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease that causes inflammation and tissue damage in multiple organs, including the skin, joints, kidneys, heart, lungs, blood cells, and nervous system. Lupus occurs when the immune system produces autoantibodies—such as ANA, anti-dsDNA, and anti-Smith—that attack the body’s own cells. Key symptoms include malar rash, photosensitivity, arthritis, painless oral ulcers, Raynaud’s phenomenon, fatigue, anemia, proteinuria, pleuritis, and neuropsychiatric problems. Lupus nephritis is one of the most serious complications. Diagnosis uses ANA screening, specific antibodies, complement levels, and kidney biopsy. Treatment focuses on reducing immune overactivity and preventing flares. Hydroxychloroquine is the main therapy, while corticosteroids, immunosuppressants (mycophenolate, cyclophosphamide), and biologics (belimumab, rituximab) are used based on severity. Lifestyle measures such as sun protection, exercise, stress control, and quitting smoking are essential. With early diagnosis and consistent treatment, most lupus patients can achieve good disease control and maintain quality of life.
