This booklet is for people who have systemic lupus erythematosus, commonly called SLE or lupus, as well as for their family and friends and others who want to better understand the disease. The booklet describes the disease and its symptoms and contains information about diagnosis and treatment as well as current research efforts supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) and other components of the Department of Health and Human Services' National Institutes of Health (NIH). It also discusses issues such as health care, pregnancy, and quality of life for people with lupus. If you have further questions after reading this booklet, you may wish to discuss them with your doctor.
Lupus is one of many disorders of the immune system known as autoimmune diseases. In autoimmune diseases, the immune system turns against parts of the body it is designed to protect. This leads to inflammation and damage to various body tissues. Lupus can affect many parts of the body, including the joints, skin, kidneys, heart, lungs, blood vessels, and brain. Although people with the disease may have many different symptoms, some of the most common ones include extreme fatigue, painful or swollen joints (arthritis), unexplained fever, skin rashes, and kidney problems.
At present, there is no cure for lupus. However, lupus can be effectively treated with drugs, and most people with the disease can lead active, healthy lives. Lupus is characterized by periods of illness, called flares, and periods of wellness, or remission. Understanding how to prevent flares and how to treat them when they do occur helps people with lupus maintain better health. Intense research is underway, and scientists funded by the NIH are continuing to make great strides in understanding the disease, which may ultimately lead to a cure.
Two of the major questions researchers are studying are who gets lupus and why. We know that many more women than men have lupus. Lupus is three times more common in African American women than in Caucasian women and is also more common in women of Hispanic, Asian, and Native American descent. In addition, lupus can run in families, but the risk that a child or a brother or sister of a patient will also have lupus is still quite low. It is difficult to estimate how many people in the United States have the disease because its symptoms vary widely and its onset is often hard to pinpoint.
Lupus can be effectively treated with drugs, and most people with the disease can lead active, healthy lives.
There are several kinds of lupus:
- Systemic lupus erythematosus (SLE)
is the form of the disease that most people are referring to
when they say "lupus." The word "systemic" means the disease can
affect many parts of the body. The symptoms of SLE may be mild
or serious. Although SLE usually first affects people between
the ages of 15 and 45 years, it can occur in childhood or later
in life as well. This booklet focuses on SLE.
- Discoid lupus erythematosus is a
chronic skin disorder in which a red, raised rash appears on the
face, scalp, or elsewhere. The raised areas may become thick and
scaly and may cause scarring. The rash may last for days or
years and may recur. A small percentage of people with discoid
lupus have or develop SLE later.
- Subacute cutaneous lupus
erythematosus refers to skin lesions that appear on parts of the
body exposed to sun. The lesions do not cause scarring.
- Drug-induced lupus is a form of
lupus caused by medications. Many different drugs can cause
drug-induced lupus. Symptoms are similar to those of SLE
(arthritis, rash, fever, and chest pain) and they typically go
away completely when the drug is stopped. The kidneys and brain
are rarely involved.
- Neonatal lupus is a rare disease
that can occur in newborn babies of women with SLE, Sjögren's
syndrome, or no disease at all. Scientists suspect that neonatal
lupus is caused by autoantibodies in the mother's blood called
anti-Ro (SSA) and anti-La (SSB). Autoantibodies ("auto" means
self) are blood proteins that act against the body's own parts.
At birth, the babies have a skin rash, liver problems, and low
blood counts. These symptoms gradually go away over several
months. In rare instances, babies with neonatal lupus may have a
serious heart problem that slows down the natural rhythm of the
heart. Neonatal lupus is rare, and most infants of mothers with
SLE are entirely healthy. All women who are pregnant and known
to have anti-Ro (SSA) or anti-La (SSB) antibodies should be
monitored by echocardiograms (a test that monitors the heart and
surrounding blood vessels) during the 16th and 30th weeks of
It is important for women with SLE or other related autoimmune disorders to be under a doctor's care during pregnancy. Physicians can now identify mothers at highest risk for complications, allowing for prompt treatment of the infant at or before birth. SLE can also flare during pregnancy, and prompt treatment can keep the mother healthier longer.
Lupus is a complex disease, and its cause is unknown. It is likely that a combination of genetic, environmental, and possibly hormonal factors work together to cause the disease. Scientists are making progress in understanding lupus, as described here and in the "Current Research" section of this booklet. The fact that lupus can run in families indicates that its development has a genetic basis. Recent research suggests that genetics plays an important role; however, no specific "lupus gene" has been identified yet. Studies suggest that several different genes may be involved in determining a person's likelihood of developing the disease, which tissues and organs are affected, and the severity of disease. However, scientists believe that genes alone do not determine who gets lupus and that other factors also play a role. Some of the factors scientists are studying include sunlight, stress, certain drugs, and infectious agents such as viruses.
It is likely that a combination of...factors work together to cause the disease.
In lupus, the body's immune system does not work as it should. A healthy immune system produces proteins called antibodies and specific cells called lymphocytes that help fight and destroy viruses, bacteria, and other foreign substances that invade the body. In lupus, the immune system produces antibodies against the body's healthy cells and tissues. These antibodies, called autoantibodies, contribute to the inflammation of various parts of the body and can cause damage to organs and tissues. The most common type of autoantibody that develops in people with lupus is called an antinuclear antibody (ANA) because it reacts with parts of the cell's nucleus (command center). Doctors and scientists do not yet understand all of the factors that cause inflammation and tissue damage in lupus, and researchers are actively exploring them.
Each person with lupus has slightly different symptoms that can range from mild to severe and may come and go over time. However, some of the most common symptoms of lupus include painful or swollen joints (arthritis), unexplained fever, and extreme fatigue. A characteristic red skin rash-the so-called butterfly or malar rash-may appear across the nose and cheeks. Rashes may also occur on the face and ears, upper arms, shoulders, chest, and hands. Because many people with lupus are sensitive to sunlight (called photosensitivity), skin rashes often first develop or worsen after sun exposure.
Symptoms can range from mild to severe and may come and go over time.
Other symptoms of lupus include chest pain, hair loss, anemia (a decrease in red blood cells), mouth ulcers, and pale or purple fingers and toes from cold and stress. Some people also experience headaches, dizziness, depression, confusion, or seizures. New symptoms may continue to appear years after the initial diagnosis, and different symptoms can occur at different times. In some people with lupus, only one system of the body, such as the skin or joints, is affected. Other people experience symptoms in many parts of their body. Just how seriously a body system is affected varies from person to person. The following systems in the body also can be affected by lupus.
- Kidneys: Inflammation of the kidneys (nephritis) can impair their ability to get rid of waste products and other toxins from the body effectively. There is usually no pain associated with kidney involvement, although some patients may notice swelling in their ankles. Most often, the only indication of kidney disease is an abnormal urine or blood test. Because the kidneys are so important to overall health, lupus affecting the kidneys generally requires intensive drug treatment to prevent permanent damage.
- Lungs: Some people with lupus develop pleuritis, an inflammation of the lining of the chest cavity that causes chest pain, particularly with breathing. Patients with lupus also may get pneumonia.
- Central nervous system: In some patients, lupus affects the brain or central nervous system. This can cause headaches, dizziness, memory disturbances, vision problems, seizures, stroke, or changes in behavior.
- Blood vessels: Blood vessels may become inflamed (vasculitis), affecting the way blood circulates through the body. The inflammation may be mild and may not require treatment or may be severe and require immediate attention.
- Blood: People with lupus may develop anemia, leukopenia (a decreased number of white blood cells), or thrombocytopenia (a decrease in the number of platelets in the blood, which assist in clotting). Some people with lupus may have an increased risk for blood clots.
- Heart: In some people with lupus, inflammation can occur in the heart itself (myocarditis and endocarditis) or the membrane that surrounds it (pericarditis), causing chest pains or other symptoms. Lupus can also increase the risk of atherosclerosis (hardening of the arteries).
Diagnosing lupus can be difficult. It may take months or even years for doctors to piece together the symptoms to diagnose this complex disease accurately. Making a correct diagnosis of lupus requires knowledge and awareness on the part of the doctor and good communication on the part of the patient. Giving the doctor a complete, accurate medical history (for example, what health problems you have had and for how long) is critical to the process of diagnosis. This information, along with a physical examination and the results of laboratory tests, helps the doctor consider other diseases that may mimic lupus, or determine if the patient truly has the disease. Reaching a diagnosis may take time as new symptoms appear.
No single test can determine whether a person has lupus, but several laboratory tests may help the doctor to make a diagnosis. The most useful tests identify certain autoantibodies often present in the blood of people with lupus. For example, the antinuclear antibody (ANA) test is commonly used to look for autoantibodies that react against components of the nucleus, or "command center," of the body's cells. Most people with lupus test positive for ANA; however, there are a number of other causes of a positive ANA besides lupus, including infections, other autoimmune diseases, and occasionally as a finding in healthy people. The ANA test simply provides another clue for the doctor to consider in making a diagnosis. In addition, there are blood tests for individual types of autoantibodies that are more specific to people with lupus, although not all people with lupus test positive for these and not all people with these antibodies have lupus. These antibodies include anti-DNA, anti-Sm, anti-RNP, anti-Ro (SSA), and anti-La (SSB). The doctor may use these antibody tests to help make a diagnosis of lupus.
It may take months or even years for doctors to piece together the symptoms to accurately diagnose this complex disease.
Some tests are used less frequently but may be helpful if the cause of a person's symptoms remains unclear. The doctor may order a biopsy of the skin or kidneys if those body systems are affected. Some doctors may order a test for anticardiolipin (or antiphospholipid) antibody. The presence of this antibody may indicate increased risk for blood clotting and increased risk for miscarriage in pregnant women with lupus. Again, all these tests merely serve as tools to give the doctor clues and information in making a diagnosis. The doctor will look at the entire picture-medical history, symptoms, and test results-to determine if a person has lupus.
Other laboratory tests are used to monitor the progress of the disease once it has been diagnosed. A complete blood count, urinalysis, blood chemistries, and the erythrocyte sedimentation rate (ESR) test can provide valuable information. Another common test measures the blood level of a group of substances called complement. People with lupus often have increased ESRs and low complement levels, especially during flares of the disease. X rays and other imaging tests can help doctors see the organs affected by SLE.
Diagnosing and treating lupus are often a team effort between the patient and several types of health care professionals. A person with lupus can go to his or her family doctor or internist, or can visit a rheumatologist. A rheumatologist is a doctor who specializes in rheumatic diseases (arthritis and other inflammatory disorders, often involving the immune system). Clinical immunologists (doctors specializing in immune system disorders) may also treat people with lupus. As treatment progresses, other professionals often help. These may include nurses, psychologists, social workers, nephrologists (doctors who treat kidney disease), hematologists (doctors specializing in blood disorders), dermatologists (doctors who treat skin disease), and neurologists (doctors specializing in disorders of the nervous system).
Treatment plans are tailored to the individual's needs and may change over time.
The range and effectiveness of treatments for lupus have increased dramatically, giving doctors more choices in how to manage the disease. It is important for the patient to work closely with the doctor and take an active role in managing the disease. Once lupus has been diagnosed, the doctor will develop a treatment plan based on the patient's age, sex, health, symptoms, and lifestyle. Treatment plans are tailored to the individual's needs and may change over time. In developing a treatment plan, the doctor has several goals: to prevent flares, to treat them when they do occur, and to minimize organ damage and complications. The doctor and patient should reevaluate the plan regularly to ensure it is as effective as possible.
For people with joint or chest pain or fever, drugs that decrease
inflammation, called nonsteroidal anti-inflammatory drugs (NSAIDs),
are often used. While some NSAIDs, such as ibuprofen and naproxen,
are available over the counter, a doctor's prescription is
necessary for others. NSAIDs may be used alone or in combination
with other types of drugs to control pain, swelling, and fever.
Even though some NSAIDs may be purchased without a prescription,
it is important that they be taken under a doctor's direction.
Common side effects of NSAIDs can include stomach upset,
heartburn, diarrhea, and fluid retention. Some people with lupus
also develop liver, kidney, or even neurological complications,
making it especially important to stay in close contact with the
doctor while taking these medications.
Antimalarials: Antimalarials are another type of drug commonly used to treat lupus. These drugs were originally used to treat malaria, but doctors have found that they also are useful for lupus. A common antimalarial used to treat lupus is hydroxychloroquine (Plaquenil)*. It may be used alone or in combination with other drugs and generally is used to treat fatigue, joint pain, skin rashes, and inflammation of the lungs. Clinical studies have found that continuous treatment with antimalarials may prevent flares from recurring. Side effects of anti-malarials can include stomach upset and, extremely rarely, damage to the retina of the eye.

Also, if a particular brand name is not mentioned, this does not mean or imply that the product is unsatisfactory.
Corticosteroids: The mainstay of lupus treatment involves the use of corticosteroid hormones, such as prednisone (Deltasone), hydrocortisone, methylprednisolone (Medrol), and dexamethasone (Decadron, Hexadrol). Corticosteroids are related to cortisol, which is a natural anti-inflammatory hormone. They work by rapidly suppressing inflammation. Corticosteroids can be given by mouth, in creams applied to the skin, or by injection. Because they are potent drugs, the doctor will seek the lowest dose with the greatest benefit. Short-term side effects of corticosteroids include swelling, increased appetite, and weight gain. These side effects generally stop when the drug is stopped. It is dangerous to stop taking corticosteroids suddenly, so it is very important that the doctor and patient work together in changing the corticosteroid dose. Sometimes doctors give very large amounts of corticosteroid by vein over a brief period of time (days) ("bolus" or "pulse" therapy). With this treatment, the typical side effects are less likely and slow withdrawal is unnecessary.
Long-term side effects of corticosteroids can include stretch marks on the skin, weakened or damaged bones (osteoporosis and osteonecrosis), high blood pressure, damage to the arteries, high blood sugar (diabetes), infections, and cataracts. Typically, the higher the dose and the longer they are taken, the greater the risk and severity of side effects. Researchers are working to develop ways to limit or offset the use of corticosteroids. For example, corticosteroids may be used in combination with other, less potent drugs, or the doctor may try to slowly decrease the dose once the disease is under control. People with lupus who are using corticosteroids should talk to their doctors about taking supplemental calcium and vitamin D or other drugs to reduce the risk of osteoporosis (weakened, fragile bones).
It is dangerous to stop taking corticosteroids suddenly, so it is very important that the doctor and patient work together in changing the dose.
Immunosuppressives: For some patients whose kidneys or central nervous systems are affected by lupus, a type of drug called an immunosuppressive may be used. Immunosuppressives, such as cyclophosphamide (Cytoxan) and mycophenolate mofetil (CellCept), restrain the overactive immune system by blocking the production of immune cells. These drugs may be given by mouth or by infusion (dripping the drug into the vein through a small tube). Side effects may include nausea, vomiting, hair loss, bladder problems, decreased fertility, and increased risk of cancer and infection. The risk for side effects increases with the length of treatment. As with other treatments for lupus, there is a risk of relapse after the immunosuppressives have been stopped.
Other Therapies: In some patients, methotrexate (Folex, Mexate, Rheumatrex), a disease-modifying antirheumatic drug, may be used to help control the disease. Working closely with the doctor helps ensure that treatments for lupus are as successful as possible. Because some treatments may cause harmful side effects, it is important to report any new symptoms to the doctor promptly. It is also important not to stop or change treatments without talking to the doctor first.
Alternative and Complementary Therapies: Because of the nature and cost of the medications used to treat lupus and the potential for serious side effects, many patients seek other ways of treating the disease. Some alternative approaches people have tried include special diets, nutritional supplements, fish oils, ointments and creams, chiropractic treatment, and homeopathy. Although these methods may not be harmful in and of themselves, and may be associated with symptomatic or psychosocial benefit, no research to date shows that they affect the disease process or prevent organ damage. Some alternative or complementary approaches may help the patient cope or reduce some of the stress associated with living with a chronic illness. If the doctor feels the approach has value and will not be harmful, it can be incorporated into the patient's treatment plan. However, it is important not to neglect regular health care or treatment of serious symptoms. An open dialogue between the patient and physician about the relative values of complementary and alternative therapies allows the patient to make an informed choice about treatment options.
Because some treatments may cause harmful side effects...report any new symptoms to the doctor promptly.
Despite the symptoms of lupus and the potential side-effects of treatment, people with lupus can maintain a high quality of life overall. One key to managing lupus is to understand the disease and its impact. Learning to recognize the warning signs of a flare can help the patient take steps to ward it off or reduce its intensity. Many people with lupus experience increased fatigue, pain, a rash, fever, abdominal discomfort, headache, or dizziness just before a flare. Developing strategies to prevent flares can also be helpful, such as learning to recognize your warning signals and maintaining good communication with your doctor.
It is also important for people with lupus to receive regular health care, instead of seeking help only when symptoms worsen. Results from a medical exam and laboratory work on a regular basis allows the doctor to note any changes and to identify and treat flares early. The treatment plan, which is tailored to the individual's specific needs and circumstances, can be adjusted accordingly. If new symptoms are identified early, treatments may be more effective. Other concerns also can be addressed at regular checkups. The doctor can provide guidance about such issues as the use of sunscreens, stress reduction, and the importance of structured exercise and rest, as well as birth control and family planning. Because people with lupus can be more susceptible to infections, the doctor may recommend yearly influenza vaccinations or pneumococcal vaccinations for some patients.
Women with lupus should receive regular preventive health care, such as gynecological and breast examinations. Men with lupus should have the prostate-specific antigen (PSA) test. Both men and women need to have their blood pressure and cholesterol checked on a regular basis. If a person is taking corticosteroids or antimalarial medications, an eye exam should be done at least yearly to screen for and treat eye problems.
Learning to recognize the warning signs of a flare can help the patient take steps to ward it off or reduce its intensity.
Staying healthy requires extra effort and care for people with lupus, so it becomes especially important to develop strategies for maintaining wellness. Wellness involves close attention to the body, mind, and spirit. One of the primary goals of wellness for people with lupus is coping with the stress of having a chronic disorder. Effective stress management varies from person to person. Some approaches that may help include exercise, relaxation techniques such as meditation, and setting priorities for spending time and energy.
Developing and maintaining a good support system is also important. A support system may include family, friends, medical professionals, community organizations, and support groups. Participating in a support group can provide emotional help, boost self-esteem and morale, and help develop or improve coping skills. (For more information on support groups, see the "Additional Resources" section at the end of this booklet.)
Learning more about lupus may also help. Studies have shown that patients who are well-informed and participate actively in their own care experience less pain, make fewer visits to the doctor, build self-confidence, and remain more active.
Although a lupus pregnancy is considered high risk, most women with lupus carry their babies safely to the end of their pregnancy. Women with lupus have a higher rate of miscarriage and premature births compared with the general population. In addition, women who have antiphospholipid antibodies are at a greater risk of miscarriage in the second trimester because of their increased risk of blood clotting in the placenta. Lupus patients with a history of kidney disease have a higher risk of preeclampsia (hypertension with a buildup of excess watery fluid in cells or tissues of the body). Pregnancy counseling and planning before pregnancy are important. Ideally, a woman should have no signs or symptoms of lupus and be taking no medications for at least 6 months before she becomes pregnant.
Pregnancy counseling and planning before pregnancy are important.
Some women may experience a mild to moderate flare during or after their pregnancy; others do not. Pregnant women with lupus, especially those taking corticosteroids, also are more likely to develop high blood pressure, diabetes, hyperglycemia (high blood sugar), and kidney complications, so regular care and good nutrition during pregnancy are essential. It is also advisable to have access to a neonatal (newborn) intensive care unit at the time of delivery in case the baby requires special medical attention.
Lupus is the focus of intense research as scientists try to determine what causes the disease and how it can best be treated. Some of the questions they are working to answer include: Why are women more likely than men to have the disease? Why are there more cases of lupus in some racial and ethnic groups? What goes wrong in the immune system, and why? How can we correct the way the immune system functions once something goes wrong? What treatment approaches will work best to lessen lupus symptoms? How do we cure lupus?
To help answer these questions, scientists are developing new and better ways to study the disease. They are doing laboratory studies that compare various aspects of the immune systems of people with lupus with those of other people both with and without lupus. They also use mice with disorders resembling lupus to better understand the abnormalities of the immune system that occur in lupus and to identify possible new therapies.
The National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), a component of the Department of Health and Human Services' National Institutes of Health (NIH), has a major focus on lupus research in its on campus program in Bethesda, Maryland. By evaluating patients with lupus and their relatives, researchers oncampus are learning more about how lupus develops and changes over time. The NIAMS also funds many lupus researchers across the United States. Some of these researchers are studying the genetic factors that increase a person's risk for developing lupus. To help scientists gain new knowledge, the NIAMS also has established Specialized Centers of Research devoted specifically to lupus research. In addition, the NIAMS is funding lupus registries that gather medical information as well as blood and tissue samples from patients and their relatives. This gives researchers across the country access to information and materials they can use to help identify genes that determine susceptibility to the disease.
Scientists are developing new and better ways to study the disease.
Identifying genes that play a role in the development of lupus is an active area of research. For example, researchers suspect that a genetic defect in a cellular process called apoptosis, or "programmed cell death," exists in people with lupus. Apoptosis is similar to the process that causes leaves to turn color in autumn and fall from trees; it allows the body to eliminate cells that have fulfilled their function and typically need to be replaced. If there is a problem in the apoptosis process, harmful cells may stay around and do damage to the body's own tissues. For example, in a mutant mouse strain that develops a lupus-like illness, one of the genes that controls apoptosis is defective. When it is replaced by a normal gene, the mice no longer develop signs of the disease. Scientists are studying what role genes involved in apoptosis may play in human disease development.
Studying genes for complement, a series of proteins in the blood that play an important part in the immune system, is another active area of lupus research. Complement acts as a backup for antibodies, helping them destroy foreign substances that invade the body. If there is a decrease in complement, the body is less able to fight or destroy foreign substances. If these substances are not removed from the body, the immune system may become overactive and begin to make autoantibodies.
Identifying genes that play a role in the development of lupus is an active area of research.
Recent large studies of families with lupus have identified a number of genetic regions that appear to be associated with risk of SLE. Although the specific genes and their function remain unknown, intensive work in mapping the entire human genome offers promise that these genes will be identified in the near future. This should provide knowledge of the complex factors that contribute to lupus susceptibility.
NIAMS-funded researchers are uncovering the impact of genetic, socioeconomic, and cultural factors on the course and outcome of lupus in Hispanics, African Americans, and Caucasians. Preliminary data show that African American and Hispanic lupus patients typically have more kidney damage compared with Caucasians. In addition, NIAMS-funded researchers found that African American lupus patients have more skin damage compared with Hispanics and Caucasians, and that the death rate from lupus is higher in African Americans and Hispanics compared with Caucasians.
It is thought that autoimmune diseases, such as lupus, occur when a genetically susceptible individual encounters an unknown environmental agent or trigger. In this circumstance, an abnormal immune response can be initiated that leads to the signs and symptoms of lupus. Research has focused on both the genetic susceptibility and the environmental trigger. Although the environmental trigger remains unknown, microbial agents such as Epstein-Barr virus and others have been considered. Researchers also are studying other factors that may affect a person's susceptibility to lupus. For example, because lupus is more common in women than in men, some researchers are investigating the role of hormones and other male-female differences in the development and course of the disease. A current study funded by the NIH is focusing on the safety and effectiveness of oral contraceptives (birth-control pills) and hormone replacement therapy in women with lupus. Doctors have worried about the wisdom of prescribing oral contraceptives or estrogen replacement therapy for women with lupus because of a widely held view that estrogens can make the disease worse. Oral contraceptives and estrogen replacement therapy do not, as once feared, appear to intensify lupus symptoms. Scientists do not know the effects of oral contraceptives on women with antiphospholipid antibody syndrome.
Patients with lupus are at risk of developing atherosclerotic vascular disease (hardening of the blood vessels that can cause heart attack, angina, or stroke). The increased risk is due partly to having lupus and partly to steroid therapy. Preventing atherosclerotic vascular disease in lupus patients is a new area of study. NIAMS-funded researchers are studying the most effective ways to manage cardiovascular risk factors and prevent cardiovascular disease in adult lupus patients.
In childhood lupus, researchers are evaluating the safety and effectiveness of drugs called statins that lower LDL (or bad) cholesterol levels as a method of preventing fat buildup in the blood vessels.
Research has focused on both the genetic susceptibility and the environmental trigger.
One out of five lupus patients experiences symptoms such as headaches, dizziness, memory disturbances, stroke, or changes in behavior that result from changes in the brain or other parts of the central nervous system. Such lupus patients have what is called "neuropsychiatric" lupus. NIAMS-funded scientists are applying new tools such as brain imaging techniques to discover cellular activity and specific genes that may cause neuropsychiatric lupus. By uncovering the mechanisms responsible for central nervous system damage in lupus patients, researchers hope to move closer to improved diagnosis and treatment for patients with neuropsychiatric lupus.
Researchers are focusing on finding better treatments for lupus. A primary goal of this research is to develop treatments that can effectively minimize the use of corticosteroids. Scientists are trying to identify combination therapies that may be more effective than single treatment approaches. Another goal is to improve the treatment and management of lupus in the kidneys and central nervous system. For example, a 20- year study supported by the NIAMS and the NIH found that combining cyclophosphamide with prednisone helped delay or prevent kidney failure, a serious complication of lupus.
Scientists are using novel "biologic agents" to selectively block parts of the immune system.
On the basis of new information about the disease process, scientists are using novel "biologic agents" to selectively block parts of the immune system. Development and testing of these new drugs, which are based on compounds that occur naturally in the body, comprise an exciting and promising new area of lupus research. The hope is that these treatments not only will be effective, but also will have fewer side effects. Preliminary research suggests that white blood cells known as B cells may play a key role in the development of lupus. Biologics that interfere with B cell function or block the interactions of immune cells are active areas of research. These targeted treatments hold promise because they have the advantage of reduced side effects and adverse reactions compared with conventional therapies. Clinical trials are testing the safety and effectiveness of rituximab (also called anti-CD20) in treating people with lupus. Rituximab is a genetically engineered antibody that blocks the production of B cells. Other treatment options currently being explored include reconstructing the immune system by bone marrow transplantation. In the future, gene therapy also may play an important role in lupus treatment.
With research advances and a better understanding of lupus, the prognosis for people with lupus today is far brighter than it was even 20 years ago. It is possible to have lupus and remain active and involved with life, family, and work. As current research efforts unfold, there is continued hope for new treatments, improvements in quality of life, and, ultimately, a way to prevent or cure the disease. The research efforts of today may yield the answers of tomorrow, as scientists continue to unravel the mysteries of lupus.
