Lupus: Causes, Symptoms, and Treatment Options

What Is Lupus?

Lupus is a chronic autoimmune disease where the immune system mistakenly attacks healthy tissues, causing inflammation, pain, and damage to various parts of the body. The most common type is systemic lupus erythematosus (SLE), which can affect the skin, joints, kidneys, brain, and other organs.

Common Lupus Symptoms
Symptoms vary widely but often include:

• Joint pain and swelling (arthritis)

• Fatigue

• Fever over 100°F

• Butterfly-shaped facial rash (malar rash)

• Sensitivity to sunlight

• Hair loss

• Chest pain during deep breaths (pleurisy)

• Mouth or nose sores

• Raynaud's phenomenon (pale or purple fingers/toes in cold)

Early Signs: Fatigue, joint pain, and skin rashes may appear early on, often worsening after sun exposure.

What Causes Lupus?
While the exact cause is unknown, lupus likely results from a combination of:

• Genetic factors: Certain genes increase susceptibility.

• Hormonal factors: Estrogen may influence lupus development, explaining its prevalence in women.

• Environmental triggers: UV light, infections (like Epstein-Barr virus), stress, smoking, and exposure to chemicals can trigger lupus.

• Medications: Some drugs can induce lupus-like symptoms, which usually subside after discontinuation.

Types of Lupus

1. Systemic Lupus Erythematosus (SLE): Affects multiple organs.

2. Cutaneous Lupus: Affects the skin, causing rashes.

3. Drug-Induced Lupus: Triggered by certain medications.

4. Neonatal Lupus: A rare condition affecting infants born to mothers with lupus antibodies.

How Is Lupus Diagnosed?

• Physical Exam: Checking for rashes, joint swelling, and other symptoms.

• Blood Tests: ANA (antinuclear antibody), anti-dsDNA, and others.

• Urinalysis: Detects kidney involvement.

• Biopsy: Skin or kidney biopsies may be performed for confirmation.

Lupus Treatment Options While there's no cure, treatments focus on managing symptoms and preventing flare-ups:

• Anti-inflammatory drugs (NSAIDs): For joint pain and inflammation.

• Antimalarials (e.g., hydroxychloroquine): For skin and joint symptoms.

• Corticosteroids: Reduce inflammation.

• Immunosuppressants: Control the overactive immune response.

• Biologics (e.g., belimumab): Target specific immune pathways.

Managing Lupus

• Sun Protection: Use sunscreen and wear protective clothing.

• Healthy Lifestyle: Regular exercise, balanced diet, and stress management.

• Regular Medical Checkups: Monitor for complications and adjust treatments as needed.

Potential Lupus Complications

• Kidney damage (lupus nephritis)

• Heart and lung issues

• Blood disorders (anemia, clotting issues)

• Neurological problems (seizures, memory issues)

When to See a Doctor Seek medical advice if you experience new or worsening symptoms, such as chest pain, breathing difficulties, or severe fatigue. Immediate medical attention is needed for signs of organ involvement.
