Systemic lupus erythematosus
Disseminated lupus erythematosus; SLE; Lupus; Lupus erythematosus; Butterfly rash - SLE; Discoid lupusSystemic lupus erythematosus (SLE) is an autoimmune disease. In this disease, the immune system of the body mistakenly attacks healthy tissue. It can affect the skin, joints, kidneys, brain, and other organs.

The cause of SLE is not clearly known. It may be linked to the following factors:
- Genetic
- Environmental
- Hormonal
- Certain medicines
SLE is more common in women than men by nearly 10 to 1. It may occur at any age. However, it appears most often in young women between the ages of 15 and 44. In the US, the disease is more common in African Americans, Asian Americans, African Caribbeans, and Hispanic Americans.
Symptoms
Symptoms vary from person to person, and may come and go. Everyone with SLE has joint pain and swelling at some time. Some develop arthritis. SLE often affects the joints of the fingers, hands, wrists, and knees.

Systemic lupus erythematosus
Systemic lupus erythematosus is a chronic inflammatory autoimmune disorder which may affect many organ systems including the skin, joints and internal organs. The disease may be mild or severe and life-threatening. African-Americans and Asians are disproportionately affected.
Exams and Tests
The American and European Rheumatology societies have published classification criteria to assist the diagnosis of SLE. These include specific symptoms, physical finding and laboratory tests. Nearly all people with SLE have a positive test for antinuclear antibody (ANA). However, having a positive ANA alone does not mean you have SLE.
The health care provider will do a complete physical exam. You may have a rash, arthritis, or swelling in the ankles. There may be an abnormal sound called a heart friction rub or pleural friction rub. Your provider will also do a nervous system exam.
Tests used to diagnose SLE may include:
- Antinuclear antibody (ANA)
-

Treatment
There is no cure for SLE. The goal of treatment is to control symptoms. Severe symptoms that involve the heart, lungs, kidneys, and other organs often need treatment by specialists. Each person with SLE needs evaluation regarding:
- How active the disease is
- What part of the body is affected
- What form of treatment is needed
Mild forms of the disease may be treated with:
- Nonsteroidal anti-inflammatory drugs (NSAIDs) for joint symptoms and pleurisy. Talk to your provider before taking these medicines.
- Low doses of corticosteroids, such as prednisone, for skin and arthritis symptoms.
- Corticosteroid creams for skin rashes.
- Hydroxychloroquine, a medicine also used to treat malaria.
- Methotrexate may be used to reduce the dose of corticosteroids.
- Belimumab and anifrolumab are biologic medicines that may be helpful in some people.
Treatments for more severe SLE may include:
- High-dose corticosteroids.
- Immunosuppressive medicines (these medicines suppress the immune system). These medicines are used if you have severe SLE that is affecting your nervous system, kidney, or other organs. They may also be used if you do not get better with corticosteroids, or if your symptoms get worse when you stop taking corticosteroids.
- Medicines most commonly used include mycophenolate, azathioprine, cyclophosphamide, and valcosporin. Because of its toxicity, cyclophosphamide is limited to a short course of 3 to 6 months. Rituximab (Rituxan) is used in some cases as well.
- Blood thinners, such as warfarin (Coumadin), for clotting disorders such as antiphospholipid syndrome.
If you have SLE, it is also important to:
- Wear protective clothing, sunglasses, and sunscreen when in the sun.
- Get preventive heart care.
- Stay up-to-date with immunizations.
- Have tests to screen for thinning of the bones (osteoporosis).

Read Article Now Book Mark ArticleOutlook (Prognosis)
The outcome for people with SLE has improved in recent years. Many people with SLE have mild symptoms. How well you do depends on how severe the disease is. Most people with SLE will require medicines for a long time. Nearly all will require hydroxychloroquine indefinitely. However, in the United States, SLE is one of the top 20 leading causes of death in females between the ages of 5 and 64. Many new medicines are being studied to improve the outcome of women with SLE.
The disease tends to be more active:
- During the first years after diagnosis
- In people younger than 40 years
Many women with SLE can get pregnant and deliver a healthy baby. A good outcome is more likely for women who receive proper treatment and do not have serious heart or kidney problems. However, the presence of certain SLE antibodies or antiphospholipid antibodies raises the risk of miscarriage.
Possible Complications
LUPUS NEPHRITIS
Some people with SLE have abnormal immune deposits in the kidney cells. This leads to a condition called lupus nephritis. People with this problem may develop kidney failure. They may need dialysis or a kidney transplant.

SLE AND PREGNANCY
Both SLE and some of the medicines used for SLE can harm an unborn child. Talk to your provider before you become pregnant. If you become pregnant, find a provider who is experienced with SLE and pregnancy.
When to Contact a Medical Professional
Contact your provider if you have symptoms of SLE. Also contact your provider if you have this disease and your symptoms get worse or a new symptom occurs.

The round or disk shaped (discoid) rash of lupus produces red, raised patches with scales. The pores (hair follicles) may be plugged. Scarring often occurs in older lesions. The majority (approximately 90%) of individuals with discoid lupus have only skin involvement as compared to more generalized involvement in systemic lupus erythematosis (SLE).
