Is It Systemic Lupus Erythematosus (SLE) or Another Type of Lupus?

Systemic Lupus Erythematosus (SLE)
SLE can affect the whole body, but not always, and not in every individual. “No two patients are the same,” says Stuart D. Kaplan, MD, a rheumatologist who practices in Hewlett, New York. Some people may have mild lupus, while others may have a more severe form of the disease.
Common SLE Symptoms
Common SLE symptoms include a rash, arthritis, fever, and fatigue, says Roberto Caricchio, MD, the chair of rheumatology and the chief of the division at the UMass Chan Medical School in Worcester, Massachusetts.
More serious complications can include:
- Kidney inflammation, or lupus nephritis, which can lead to kidney failure
- Heart disease, including pericarditis and myocarditis
- Coronary artery disease
- Stroke
- Confusion, seizures, and psychosis
- Depression
- Problems with short-term memory
- A higher risk of miscarriage and preterm labor in pregnant women
How Doctors Test for It
Rheumatologists use a combination approach, the symptoms you are experiencing plus the use various laboratory tests and criteria to diagnose systemic lupus erythematosus and prescribe a personalized medication regimen based on the patient’s symptoms, says Dr. Caricchio.
SLE Treatment
“What I tell patients is that my job is to help them get to the place where they can participate in the activities they like,” says Stacy Ardoin, MD, a rheumatologist at the Ohio State University Wexner Medical Center in Columbus.
In addition to recommending that patients regularly visit their rheumatologist to manage the disease, she encourages them to get enough sleep and exercise regularly — at least 150 minutes of moderate aerobic exercise per week — to boost heart health as well as mental health.
Cutaneous Lupus Erythematosus (CLE)
If you do have CLE, it is important to see your doctor regularly and adhere to any treatment instructions, Caricchio notes, so that treatment can be altered as necessary (and as early as possible) to identify and manage symptoms that do progress.
Discoid Lupus
A common type of cutaneous lupus is discoid lupus, which refers to the appearance of a round, raised, red, and scaly rash that does not itch. The rash typically appears on the face and scalp and can cause scarring and hair loss.
Subacute Cutaneous Lupus Erythematosus
Subacute cutaneous lupus erythematosus is another form of cutaneous erythematosus. The skin rash is red and scaly or can appear with ringed edges. Patients can have organ involvement such as fluid around the heart and lungs, but this is generally milder than with SLE, says Caricchio.
Because both forms of cutaneous lupus can be aggravated by sunlight, patients also need to avoid sun exposure.
Drug-Induced Lupus Erythematosus
The most common medications that cause the condition are isoniazid (an antibiotic used to treat tuberculosis), hydralazine (Apresoline, used for high blood pressure and heart failure), and procainamide (Pronestyl, a drug prescribed for heart rhythm problems). Other drugs that may lead to drug-induced lupus include the acne medication minocycline (Minocin) and some antiseizure medications, Dr. Ardoin adds.
If symptoms persist, doctors may prescribe NSAIDs for arthritis, steroid creams to treat skin rashes, and antimalarial drugs for both the skin and arthritis.
More rarely, doctors will prescribe high doses of corticosteroids and immunosuppressants if drug-induced lupus erythematosus is causing nephritis or inflammation around the heart or lungs. Physicians may also recommend avoiding sun exposure, which can exacerbate symptoms.
Neonatal Lupus
Neonatal lupus is a condition resulting from autoantibodies passing from a pregnant woman who has lupus or a related condition through the placenta to the baby developing in the womb, explains Virginia Pascual, MD, the director of the Drukier Institute for Children’s Health at Weill Cornell Medicine in New York City. Not all pregnancies in women with lupus or a related condition, though, will necessarily result in a baby being born with neonatal lupus.
The symptoms newborns with neonatal lupus experience, such as decreased platelets and rash, are temporary. But a rare condition called heart block, or abnormal heart rhythm, can result in heart problems or even death, Dr. Pascual says.
Doctors don’t know how to prevent neonatal lupus, but if you do have lupus and get pregnant, Kaplan suggests seeing a high-risk maternal-fetal medicine specialist to monitor your risk through your pregnancy. Your doctor should order a fetal echocardiogram 18 to 24 weeks into your pregnancy to detect heart block (which they can treat with a pacemaker implanted in utero or at birth), Kaplan explains.
The Takeaway
- Several types of lupus exist, but SLE is the most common and the one people most often refer to when they talk about lupus.
- While SLE affects various parts of the body, including many essential organs and systems, CLE is limited to the skin.
- When you understand the different types of lupus, you or your loved one can better manage the disease and get the treatment you need.
