Systemic Lupus Erythematosus
Updated: Apr 23, 2009
Introduction
Background
Systemic lupus erythematosus (SLE) is an inflammatory connective tissue disease with variable manifestations.1,2,3 SLE may affect many organ systems with immune complexes and a large array of autoantibodies, particularly antinuclear antibodies (ANAs). (See image below and Image 1.)
The classic malar rash, also known as a butterfly rash, of systemic lupus erythematosus, with distribution over the cheeks and nasal bridge. Note that the fixed erythema, sometimes with mild induration as seen here, characteristically spares the nasolabial folds.
Pathophysiology
The damage that results from systemic lupus erythematosus is caused by the excessive deposition of immune complexes and the resultant organ-specific inflammatory response found in the blood vessels, kidneys, connective tissue,4 and skin. It has not been explained why there is a female preponderance.
Frequency
United States
The incidence of systemic lupus erythematosus (SLE) in the United States is 50-100 cases per 100,000 population. A report indicates that 239,000 people in the United States have suspected or definite SLE.
International
Prevalence of systemic lupus erythematosus is about the same worldwide (50-100 cases per 100,000 population); the condition appears to be common in China and Southeast Asia, as well as in the black population of the Caribbean.5
Mortality/Morbidity
- Since the mid-20th century, the 10-year survival rate for systemic lupus erythematosus (SLE) has improved from 10% to 70-90% for individuals with SLE.6
- Female patients with onset of the disease after age 60 years have the most favorable prognosis.
- Children with SLE have a less favorable prognosis.
- Renal failure and intercurrent infections are the most common causes of death associated with SLE.
- Diffuse central nervous system (CNS) disease is another common cause of death.
- The 10-year survival in Dubois group from 1950 to 1971 was 87%, but it was only 65% in those with renal involvement.1
- It is not known why there is a female preponderance.
Race
- The highest incidence of systemic lupus erythematosus (SLE) is in Asians in Hawaii, blacks, and certain groups of Native Americans.
- African American women are 3 times more likely to be affected by SLE than are white American women.
Sex
- Systemic lupus erythematosus (SLE) occurs more frequently in women, with a female-to-male ratio of 8:1-13:1 in adults. SLE is 3 times more common in African-American women than in white women in United States.
- Women are more prone to SLE in their childbearing years.
- During the first 10 years of life, girls develop SLE 3-7 times more often than do boys.
- It is not known why there is a female preponderance.
- SLE poses a risk to pregnant women, although treatment for the disease can harm their fetus.
Age
The onset of systemic lupus erythematosus occurs primarily in patients aged 16-55 years. It is uncommon after the age of 50.
Clinical
History
Potential symptoms of systemic lupus erythematosus (SLE) include the following:
- Constitutional - These symptoms affect most patients at some point during the disease.
- Fatigue
- A general feeling of unwellness
- Fever
- Weakness
- Musculoskeletal - These symptoms most commonly affect patients early in the course of SLE, with 90% of patients having arthralgias and 50% of them experiencing inflammatory arthritis.
- Arthralgia
- Myalgia
- Nonrestorative sleep
- Cardiovascular - Raynaud phenomenon
- Pulmonary - Pleuritic chest pain
- Genitourinary - Menstrual irregularities
- Neuropsychiatric
- Headaches
- Seizures
- Anxiety disorders
- Phobias
- Manias
- Depression
- Gastrointestinal (GI)
- Diffuse abdominal pain
- Nausea/vomiting
- Dysphagia
- Photosensitivity (See image below and Image 2.)
Photosensitive systemic lupus erythematosus rashes typically occur on the face or extremities, which are sun-exposed regions. Photo courtesy of Dr. Erik Stratman, Marshfield Clinic.
Physical
Potential physical findings in systemic lupus erythematosus include the following7 :
- Constitutional
- Weight loss
- Weight gain (in patients treated with prednisone)
- Fever
- Musculocutaneous
- Hair loss
- Discoid lupus
- Acute cutaneous lupus
- Butterfly rash (See image below and Image 1.)

- Elevated
- Pruritic
- Painful

- Asymmetric mononeuritis multiplex
- Cranial nerve neuropathies
- Ophthalmologic

Causes
- The cause of systemic lupus erythematosus (SLE) is unknown.
- SLE is an immunologic disorder that involves the production of autoantibodies.8
- Sunlight can trigger the onset of SLE.
- Certain medicines may trigger SLE by initiating the immune response in susceptible individuals. The 2 most common medications that can lead to SLE are the following:
- Hydralazine
- Procainamide
- Others medications that may trigger SLE include the following:
- Anticonvulsants
- Antiemetics
- Antituberculars
- Antibiotics
