Lupus (Systemic Lupus Erythematosus) 

Lupus is an autoimmune disease. This means that the body's natural defense system (immune system) attacks healthy tissues instead of attacking only things like bacteria and viruses. This causes inflammation.
Although some people with lupus have only mild symptoms, the disease is lifelong and can become severe. But most people can control their symptoms and prevent severe damage to their organs. They do this by seeing their doctors often for checkups, getting enough rest and exercise, and taking medicines.
This topic focuses on systemic lupus erythematosus (SLE), the most common and most serious type of lupus. But there are other types of lupus, such as discoid or cutaneous lupus, drug-induced systemic lupus, and neonatal lupus.
The exact cause of lupus is not known. Experts believe that some people are born with certain genes that affect how the immune system works. These people are more likely to get lupus. Then a number of other things can trigger lupus attacks. These include viral infections, including the virus that causes mononucleosis, and sunlight.
Although these things can trigger lupus, they may affect one person but not another person.
Lupus symptoms vary widely, and they come and go. The times when symptoms get worse are called relapses, or flares. The times when symptoms are under control are called remissions.
Common symptoms include feeling very tired and having joint pain or swelling (arthritis), a fever, and a skin rash camera.gif. The rash often happens after you have been in the sun. You may have mouth sores and hair loss. Over time, some people with lupus have problems with the heartlungskidneysblood cells, or nervous system.
There is no single test for lupus. Because lupus affects different people in different ways, it can be hard to diagnose.
Your doctor will check for lupus by examining you, asking you questions about your symptoms and past health, and doing some urine and blood tests.
Treatment for lupus may include:
  • Corticosteroid cream for rashes.
  • Nonsteroidal anti-inflammatory drugs (NSAIDs) for mild joint or muscle pain and fever.
  • Antimalarial medicines to treat fatigue, joint pain, and skin rashes.
  • Corticosteroid pills if other medicines aren't controlling your symptoms.
The doctor may also recommend other medicines that slow down the immune system (immunosuppressants).


What Is Lupus?

Lupus is a lifelong disorder of the immune system. Immune cells attack the body's own healthy tissues, leading to inflammation and tissue damage. Symptoms may be limited to the skin, but more often lupus also causes internal problems such as joint pain. In severe cases, it can damage the heart, kidneys, and other vital organs. Although there's no cure, there are treatments that can minimize the damage.

Lupus Symptom: Joint Pain

Joint and muscle pain is often the first sign of lupus. This pain tends to occur on both sides of the body at the same time, particularly in the joints of the wrists, hands, fingers, and knees. The joints may look inflamed and feel warm to the touch. But unlike rheumatoid arthritis, lupus usually does not cause permanent joint damage.

Lupus Symptom: Butterfly Rash

A tell-tale sign of lupus is a butterfly-shaped rash across the cheeks and bridge of the nose. Other common skin problems include sensitivity to the sun with flaky, red spots or a scaly, purple rash on various parts of the body, including the face, neck, and arms. Some people also develop mouth sores.

Lupus Symptom: Nail Changes

Lupus can cause the nails to crack or fall off. They may be discolored with blue or reddish spots at the base. These spots are actually in the nail bed, the result of inflamed small blood vessels. Swelling may also make the skin around the base of the nail look red and puffy.

Lupus Symptoms: Fever and Fatigue

Most people with lupus experience some degree of fatigue. In many cases, it is severe enough to interfere with exercise and other daily activities. Most patients also run a low-grade fever from time to time. This unexplained fever may be the only warning sign in some people.


Lupus Symptom: Light Sensitivity

Many people with lupus are unusually sensitive to the sun and other forms of ultraviolet light. A day at the beach may trigger a skin rash in areas exposed to sunlight and may worsen other lupus symptoms. Certain medications can make people with lupus even more sensitive to UV light.


Lupus Symptom: Hair Loss

The symptoms of lupus tend to come and go, and this includes hair loss. Patients may go through periods where their hair falls out in patches or becomes thinner all across the scalp. Once the flare-up is over, new hair is likely to grow back.

Lupus Symptom: Raynaud's

Some people with lupus develop a condition called Raynaud's phenomenon. Their fingers and toes become painful, numb, and tingly in response to cold temperatures or emotional stress. This happens when small blood vessels spasm and restrict blood flow to the area. During an attack, the fingers and toes may turn white or blue. People can also have Raynaud's without having lupus or any serious health complications.

Lupus or Something Else?

When lupus begins, it can look a lot like rheumatoid arthritis, which causes joint pain and swelling, or fibromyalgia, which causes fatigue and pain. One aspect that sets lupus apart is the combination of skin rashes with joint pain and fatigue. There are also lab tests that can help distinguish lupus from other diseases.

Diagnosing Lupus

Diagnosing lupus can be tricky. The disease can mimic other conditions, and it often takes a different course in different people. Many people have it for years before developing tell-tale symptoms. Although there is no one test for lupus, certain proteins usually show up in a patient's blood. A blood test for antinuclear antibodies (ANAs) can provide a critical clue. Other lab tests may check cell counts, kidney function, and clotting time. A tissue biopsy of an involved organ such as the skin or kidneys sometimes helps with diagnosis.

Who Gets Lupus?

Anyone can get lupus. But it affects women 10 times more often than men. Aside from being female, your odds of getting the disease are higher if you are:
  • African-American, Latino, or Asian
  • Between the ages of 20 and 40
  • Related to someone with lupus

Types of Lupus

When people say "lupus," they usually mean systemic lupus erythematosus (SLE), the most common and serious type. But there are other types. Cutaneous lupus erythematosus -- also called discoid lupus -- is limited to the skin and doesn't cause the organ damage that sometimes occurs with SLE. The most common symptom is a circular rash. Drug-induced systemic lupus causes temporary lupus symptoms in people who take certain medications.

Medical Treatments for Lupus

There are ways to control the symptoms of lupus. These include corticosteroid creams for rashes and nonsteroidal anti-inflammatory drugs (NSAIDs) for joint pain and fever. Antimalarial medications can help fight joint pain, ulcers, and rashes. Corticosteroids may also be given as pills. In severe cases, they can be given intravenously. People with severe lupus may benefit from drugs that suppress the immune system.


Self-Care for Lupus

Making some changes to your routine can also help reduce lupus flare-ups:
  • Cover up when you're in the sun.
  • Don't smoke.
  • Exercise regularly.
  • Improve your stress management skills.
Also be sure to get plenty of rest. Some people with lupus need up to 12 hours of sleep a night.


Lupus and Kidney Problems

As lupus progresses, it can interfere with the body's organs. Up to three out of four people with lupus can develop kidney problems. These problems may not cause symptoms, though some people notice swelling in their legs or ankles. Most patients only learn about their kidney trouble when a urine test reveals blood or abnormal protein levels.

Lupus and Heart Problems

The most common heart problem linked to lupus is an inflammation of the sac around the heart. This may cause severe pain in the left side of the chest. People with lupus are also more likely to develop plaques that narrow or clog the arteries. This can lead to coronary artery disease. Other complications include heart valve disease and inflammation of the heart muscle. Call 911 immediately for chest pain, rather than trying figure out the cause yourself.

Lupus and Lung Problems

The tissue surrounding the lungs becomes inflamed in about a third of people with lupus. This may lead to painful breathing, or chest pain, or it may not cause any symptoms at all. Sometimes lupus causes chest pain that is not related to the lungs or the heart. Instead, the pain comes from an inflamed chest muscle or rib joint. Any chest pain should be promptly evaluated by a doctor.

Lupus and Digestive Problems

Digestive problems are not common with lupus, but some people may experience belly pain, nausea, vomiting, difficulty swallowing, or inflammation of the liver or pancreas. This can be related to lupus itself or medications used to treat the disease. Some people tend to lose weight during lupus flare-ups.

Lupus and Anemia

Lupus and the medications used to treat it can contribute to anemia in some patients. This means the body has too few red blood cells, because it is not making enough, or red blood cells are being destroyed more quickly than they can be replaced. Symptoms include fatigue and shortness of breath.

Lupus and the Nervous System

Lupus can trigger a wide range of problems with the nervous system, most commonly headaches. Mild memory problems are a less common complaint that may come and go over time. Some people with lupus have a greater risk for a stroke, and in rare cases, the disease can lead to seizures.

Lupus and Mental Health

Depression and anxiety are a risk for people with lupus. This may be the result of the condition's affect on the nervous system combined with the emotional strain of coping with a chronic illness. Be sure to discuss any concerns about your mood with your doctor or other health care provider. There are highly effective treatments for depression and anxiety.


Lupus and Pregnancy

Most women with lupus can get pregnant, though the condition increases the risk of complications during pregnancy. Because lupus symptoms come and go, the best time to get pregnant is when symptoms are at a minimum. Women who conceive when symptoms are in remission are less likely to have complications. Make sure your obstetrician knows you have lupus. Your medications may be modified and you may undergo extra monitoring to ensure a successful pregnancy.


Neonatal Lupus

Most babies born to women with lupus are entirely healthy. But in rare cases, the newborn of a mom with lupus may have neonatal lupus. This condition can cause a skin rash, anemia, or liver problems. The symptoms usually go away after a few months and don't cause permanent damage. However, some babies with neonatal lupus can be born with a serious heart problem.


Living with Lupus

The fatigue and joint pain associated with lupus can make it more difficult to do your job or care for your children. You may have to cut back on activities or ask for help when symptoms flare up. But most people with lupus are able to continue with their usual activities.


Outlook for Lupus

Thanks to improvements in treatments for lupus, people with the condition are living significantly longer. The outlook for any given individual depends on how severe the disease is, and whether any vital organs are affected. But most people with lupus can expect to live a normal or nearly normal life span.
