  • SLE

What is Lupus?

Lupus is a chronic autoimmune disease where the immune system mistakenly attacks healthy tissue instead of fighting off germs. This "friendly fire" causes inflammation and can damage the skin, joints, kidneys, brain, heart, and lungs.

Types of Lupus

  • Systemic Lupus Erythematosus (SLE): The most common and serious form, affecting various organ systems throughout the entire body.

  • Cutaneous Lupus: Limited specifically to the skin, often causing rashes or lesions.

  • Drug-induced Lupus: Triggered by certain prescription medications; symptoms typically resolve once the medicine is stopped.

What are Common Symptoms of Lupus?

Symptoms vary significantly between individuals and often "flare" (worsen) and then subside.

  • Extreme fatigue

  • Joint pain and swelling

  • "Butterfly rash" (malar rash) across the cheeks and nose

  • Sensitivity to sunlight (photosensitivity)

  • Chest pain when breathing deeply

  • Hair loss and finger/toe color changes (Raynaud's phenomenon)

  • Headaches, confusion, or memory loss

  • Anemia or blood clotting issues

What Causes Lupus?

While the exact cause is unknown, it is believed to result from a combination of genetics, hormones (as it primarily affects women of childbearing age), and environmental triggers such as:

  • Excessive sunlight exposure

  • Viral or bacterial infections

  • Significant emotional or physical stress

How is Lupus Diagnosed?

Because lupus mimics many other illnesses, there is no single definitive test. Diagnosis involves a "puzzle-piece" approach:

  • Physical Exam: Checking for rashes, joint swelling, and reviewing family history.

  • Blood Tests: Looking for inflammation markers and the Antinuclear Antibody (ANA) test, which is positive in most people with lupus.

  • Urine Analysis: Screening for protein or blood that might indicate kidney involvement.

  • Biopsy: Taking a tiny sample of skin or kidney tissue to look for specific patterns of damage.

How is Lupus Treated?

Treatment focuses on suppressing the overactive immune system and managing symptoms:

  • NSAIDs: Over-the-counter pain relievers for joint swelling and fever.

  • Antimalarials: Drugs like hydroxychloroquine to manage fatigue and skin/joint issues.

  • Corticosteroids: Powerful anti-inflammatories like prednisone to quickly calm flares.

  • Immunosuppressants: Medicines that "quiet" the immune system to protect organs.

  • Biologics: Targeted therapies that block specific proteins involved in the autoimmune response.

Trend

  • In the United States: Approximately 1.5 million people are living with lupus.

  • Demographics: About 90% of those diagnosed are women, with higher prevalence rates among African American, Hispanic, and Asian populations.

  • Projections: Numbers are expected to rise over the next five years, largely due to improved diagnostic tools and increased clinical awareness.

History

Lupus has been documented since the Middle Ages. The name "lupus" (Latin for "wolf") was coined in the 13th century because the facial lesions were thought to resemble a wolf's bite. The 1948 discovery of the "LE cell" was the first major laboratory breakthrough for diagnosis. The 1950s and 60s introduced steroids and immunosuppressants, fundamentally changing the prognosis from a frequently fatal condition to a manageable chronic illness.
