Systemic Lupus Erythematosus (SLE)

What is SLE?

Systemic Lupus Erythematosus (SLE), often just called lupus, is a chronic autoimmune disease.

  • In SLE, the body’s immune system, which normally protects against infections, mistakenly attacks healthy tissues.
  • This immune attack can affect many organs, including: joints, skin, kidneys, lungs, heart, blood cells, and the nervous system.
What Are the Symptoms of SLE?
  • Joint pain and swelling (especially hands and wrists)
  • Fatigue and low energy
  • Low-grade fever
  • Butterfly-shaped rash over cheeks and nose (malar rash)
  • Mouth ulcers
  • Hair thinning or hair loss
  • Rashes after sun exposure
  • Raynaud’s phenomenon (fingers turning white or blue in cold)
  • Swelling of feet or puffiness around the eyes (suggests kidney involvement)
What Organs Can SLE Affect?
  • Joints – inflammation like in RA, but usually no erosion
  • Skin – rashes, ulcers, photosensitivity
  • Kidneys – lupus nephritis (can cause protein loss or kidney failure)
  • Blood – low WBC, anemia, increased clotting risk
  • Heart and Lungs – pleuritis or pericarditis
  • Brain – seizures, headaches, confusion (rare)
How Is SLE Diagnosed?

Diagnosis is based on symptoms, examination, and specific tests.

  • ANA – usually positive
  • ENA , Anti-dsDNA, Anti-Sm – more specific to lupus
  • ESR/CRP/– inflammation markers and Complements C3/C4
  • Full Blood Count – check for anemia, low WBC/platelets
  • Urine test – check for kidney damage

🩺 A rheumatologist is the best doctor to diagnose and manage lupus.

Goals of Treatment
  • Control the immune system
  • Prevent organ damage
  • Reduce flares and relieve symptoms
  • Improve long-term quality of life
Treatment Options
  • NSAIDs – for mild joint/muscle pain (short-term)
  • Steroids – for flares or severe organ involvement (oral or IV)
  • Antimalarials – Hydroxychloroquine (HCQ) is a cornerstone of treatment for most lupus patients
  • Immunosuppressants – Used in moderate/severe disease or organ involvement (Azathioprine, Mycophenolate, Methotrexate, Cyclophosphamide)
  • Biologics – for difficult or resistant disease (e.g., Belimumab, Rituximab in selected cases)
  • Monitoring – regular blood and urine tests, and eye check-ups (if on hydroxychloroquine)
Multidisciplinary Care

Because SLE can affect many organs, patients may need to see different specialists:

  • A general physician – especially if there is internal organ involvement
  • A nephrologist – if kidneys are involved
  • A dermatologist – for skin and hair symptoms
  • Other specialists (e.g. cardiologist, neurologist) depending on symptoms

Most SLE cases are mild and manageable. But serious complications (e.g., kidney, heart, vasculitis, or clotting disorders) require close follow-up and more aggressive treatment.

Self-Care & Lifestyle Tips
  • Avoid sun exposure – wear protective clothing, use sunscreen
  • Engage in regular, gentle exercise
  • Get adequate rest
  • Don’t smoke – it worsens disease and complications
  • Eat a balanced diet – low salt if kidneys are involved
  • Learn to manage stress and get psychological support if needed
When to Contact Your Doctor
  • Fever, fatigue, or new joint pain
  • Sudden swelling of legs or puffiness of face
  • Rashes, mouth ulcers, or hair loss
  • Vision changes, chest pain, or shortness of breath
  • Side effects from medication
Medication Caution
  • Never stop your medications suddenly without advice
  • Immunosuppressants reduce infection-fighting capacity – report any fevers, persistent cough, or infections
  • Keep all follow-up appointments to monitor drug safety and disease activity
Final Message

SLE is a serious but manageable condition. Most patients lead full and active lives with early diagnosis, proper treatment, and regular follow-up.

Work closely with your rheumatologist and involve other specialists when necessary.

Stay informed, keep your appointments, and don’t hesitate to ask questions.
