Lupus (systemic lupus erythematosus, or SLE) is a complex autoimmune disease in which the immune system attacks healthy tissue throughout the body — including the skin, joints, kidneys, heart, lungs, and brain. If you’ve been told you may have lupus, or if you’re experiencing unexplained symptoms and are looking for answers, Dr. Adam Elisha, DO — a board-certified rheumatologist in Duluth, MN — specializes in diagnosing and managing lupus and other autoimmune conditions.
What Is Lupus?
Lupus, formally known as systemic lupus erythematosus (SLE), is a chronic autoimmune disease in which the immune system loses the ability to distinguish between healthy tissue and foreign invaders. As a result, it produces antibodies that attack the body’s own cells, causing inflammation in multiple organ systems, including the skin, joints, kidneys, heart, lungs, brain, and blood vessels. Lupus most commonly develops in women of childbearing age and follows a relapsing-remitting pattern of flares interspersed with periods of low disease activity.
There are several distinct forms of lupus. Systemic lupus erythematosus (SLE) is the most common and the form people usually mean when they say “lupus.” Other forms include cutaneous lupus (limited to the skin), drug-induced lupus (caused by certain medications and typically resolving when the drug is stopped), and neonatal lupus (a rare condition in newborns of mothers with specific autoantibodies). Because lupus can mimic many other illnesses, accurate diagnosis often requires evaluation by a rheumatologist.
Symptoms of Lupus
Lupus is called “the great imitator” because its symptoms overlap with many other conditions, making diagnosis challenging. Common symptoms include:
- A butterfly-shaped rash across the cheeks and nose (malar rash)
- Photosensitivity — skin rashes or worsening symptoms triggered by sun exposure
- Joint pain, swelling, and stiffness (typically non-erosive)
- Persistent fatigue that doesn’t improve with rest
- Fever without an obvious cause
- Hair loss (alopecia)
- Raynaud’s phenomenon — fingers and toes turning white or blue in the cold
- Chest pain with deep breathing (pleuritis or pericarditis)
- Kidney involvement (detected through urine tests showing protein or blood)
- Neurological symptoms including headaches, confusion, or memory problems
How Is Lupus Diagnosed?
Lupus diagnosis is based on a combination of symptoms, physical examination, and laboratory findings. Key tests include ANA (antinuclear antibody), anti-dsDNA, anti-Smith antibodies, complement levels (C3/C4), complete blood count, and a comprehensive metabolic panel to assess kidney function. The American College of Rheumatology has established classification criteria that help guide the diagnostic process.
Lupus Treatment Options
Lupus treatment is tailored to the organs affected and the severity of disease. Options include:
- Hydroxychloroquine (Plaquenil): A cornerstone of lupus management that reduces flare frequency and protects against organ damage.
- NSAIDs and corticosteroids: For managing acute flares and joint pain.
- Immunosuppressants: Such as mycophenolate mofetil, azathioprine, or cyclophosphamide for significant organ involvement.
- Belimumab (Benlysta): A biologic specifically approved for lupus that targets a protein that supports survival of B cells.
- Sun protection: Daily broad-spectrum SPF 50+ sunscreen and sun-protective clothing are essential, as UV exposure triggers flares.
Living with Lupus
With appropriate medical management, most people with lupus can lead full, active lives. The key is close monitoring with a rheumatologist who can adjust treatment as the disease evolves. Regular follow-up appointments, lab monitoring, and prompt attention to new symptoms are all essential components of good lupus care.
