What is lupus and who gets it?

SLE is a chronic autoimmune disease where the immune system produces autoantibodies that attack the body's own tissues. It predominantly affects women (9:1 female-to-male ratio), most commonly Black, Asian, and Hispanic women, with onset typically between ages 15–45.

How is lupus diagnosed?

Lupus diagnosis uses the 2019 EULAR/ACR classification criteria based on clinical features (butterfly rash, oral ulcers, arthritis, nephritis) and laboratory abnormalities (positive ANA, anti-dsDNA, anti-Sm antibodies, low complement C3/C4). A positive ANA alone is not diagnostic — up to 20% of healthy people are ANA-positive.

What is lupus nephritis?

Lupus nephritis is kidney inflammation caused by lupus — it occurs in 40–60% of SLE patients and is the leading cause of morbidity in lupus. Treatment involves high-dose steroids plus mycophenolate mofetil (MMF), now often with Benlysta or Lupkynis added. Without treatment, it can progress to end-stage kidney disease.

Systemic Lupus Erythematosus (Lupus)

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease where the immune system attacks multiple organs including the skin, joints, kidneys, brain, and heart. Lupus is notoriously difficult to diagnose and manage — but three new targeted therapies approved since 2021 have expanded treatment options significantly.

📊 SLE affects ~1.5 million Americans — 90% are women. Diagnosis typically occurs between ages 15–45. The 'butterfly rash' across the nose and cheeks is the signature feature, but lupus can affect virtually every organ system.

📋 Newly Diagnosed Guide

Diagnosed with lupus? What the first year should look like.

🏥

1. See a rheumatologist — find one with lupus experience

Lupus is managed by rheumatologists. The Lupus Foundation of America (lupus.org) has a provider search tool. Academic lupus centers offer multidisciplinary care.

💊

2. Start hydroxychloroquine (Plaquenil) — essentially everyone with lupus should be on it

HCQ is the backbone of lupus management. It reduces flare frequency, prevents organ damage, reduces cardiovascular risk, and improves survival. Safe long-term and inexpensive as a generic.

☀️

3. Sun protection is non-negotiable

UV light triggers lupus flares. Daily SPF 50+ sunscreen, UV-protective clothing, and avoiding peak sun hours significantly reduce flare risk. This is active disease management, not lifestyle advice.
