What is Lupus?

Autoimmune Disease Overview

Lupus is a type of autoimmune disease. It happens when the immune system wrongly attacks the body’s own healthy parts.1 This causes inflammation all over the body. It can harm the joints, skin, kidneys, blood, brain, heart, and lungs.1

Unpredictable and Misunderstood

Lupus is hard to understand and predict. It shows up with many different symptoms that might change over time.1 This makes it tough to diagnose and manage.1

Range of Symptoms

People with lupus could feel extremely tired, have a fever, and their joints might hurt and swell. They might also get skin rashes and have problems with their organs.1 The way lupus acts can make daily life tough and affect how people feel and function.1

Lupus Symptoms

The most common signs of lupus are ongoing fatigue and fever. These can hugely impact life early on. They are more seen in women. It usually starts showing between 15 and 45.134

Joint Pain and Swelling

Joint pain and swelling in the hands, wrists, and knees are typical.1

Skin Rashes and Lesions

The “butterfly-shaped rash” on the cheeks and nose is a key sign of lupus. Not everyone with lupus gets this rash.1 Other skin rashes and lesions can also occur.3

Organ Involvement

Lupus may affect organs like the kidneys, brain, heart, and lungs. This can lead to other health issues.1 Kidney failure is a major cause of death in people with lupus.1 It also raises the risk of heart disease, heart attacks, and infections due to a weak immune system.1

Lupus symptoms may come and go, including bad and good periods. Genetics, environment, sunlight, infections, and some drugs can play a part.1

Lupus can also cause brain and nerve problems. These can include headaches, vision issues, and even strokes.3

Causes of Lupus

The cause of lupus isn’t completely clear. But, we know it happens when certain genes meet certain environmental factors.12 People with certain genes might get lupus if they come across sunlight, infections, or some drugs. These factors can start the disease in those with the right genes.2 Understanding these genetic and environmental causes helps with prevention and early treatment.

Genetics and Environment

Genes are key in lupus development.2 If someone in your family has lupus or an autoimmune condition, you might get it too.2 Certain things in the environment, like viruses, sunlight, drugs, and smoking, can also bring on lupus in those already at risk.2 Problems with the immune system, like trouble clearing damaged cells, are linked to lupus.2

Potential Triggers

We don’t fully know what causes lupus, but several things can lead to its activation.2 These include sunlight, specific infections, and some drugs.2 Stress and other environmental elements might also affect how the disease starts and progresses.2

Risk Factors for Lupus

Lupus is an autoimmune disease that touches people of all types. But some things can make you more likely to get this condition. Knowing these risk factors helps doctors spot people who might get lupus. They can then offer tests and advice to help prevent it.

Gender

One big thing that makes lupus more likely is being a woman. Women face a higher risk, nine times more than men.15 This hints that hormones and biology might be part of why more women get lupus.

Age

Lupus often shows up between ages 15 and 45. It’s more common when people are in their prime baby-making years.15 But, it can really start at any age. So, healthcare workers need to watch for signs in all people, no matter their age.

Race and Ethnicity

Some groups have a higher chance of getting lupus than others. African Americans, Hispanics, and Asian Americans get it more. Meanwhile, those of European descent tend to get it less.15 This mix of who gets lupus might be because of genes, where you live, and social ways.

Knowing these risk factors helps doctors focus on people who might get lupus. They can offer special care and advice. Quick care and looking out for each person’s needs are really key for those facing lupus.

Diagnosing Lupus

Understanding whether someone has lupus can be hard. This is because its signs can look like those of many other illnesses. Doctors check your health history, do a physical exam, run lab tests, and might look at images to decide.6 The signs of Lupus are different for each person.6

6 To find out if you have lupus, blood and urine tests are key. A full blood check looks for anemia, which is common in lupus.6 The erythrocyte sedimentation rate is tested to spot diseases like lupus.6 Checking the kidneys and liver is important too.6 While an Antinuclear Antibody (ANA) test is often done, a positive result doesn’t always mean you have lupus.6 Tests like chest X-rays and echocardiograms can check lung and heart health.6 Sometimes, doctors need to do kidney biopsies to plan treatment.

7 Because lupus shows up like other diseases and there is no one test, it can be tricky to diagnose.7 Most people with lupus test positive for ANA.8 If lupus is active, you’re likely to have antinuclear antibodies.8

Getting a reliable diagnosis for lupus is critical. It helps tailor the right treatment and care plan.

Treatment Options for Lupus

Managing lupus means using both medicines and lifestyle changes. There’s no cure for lupus yet, but many treatments can help. They can improve symptoms, lessen inflammation, and lower the risk of complications.

Medications

Medicine is a key part of treating lupus. Drugs like hydroxychloroquine cut the chance of severe episodes by half and prevent blood clots. Belimumab, approved by the FDA, helps too.9 For harder cases, doctors might use prednisone and azathioprine. Seizures get treated with anticonvulsants. Infections may need antibiotics.9 High blood pressure, high cholesterol, and osteoporosis can be worries. Meds for these, like antihypertensives, statins, and osteoporosis meds, may be part of treatment.9

Lifestyle Changes

Lifestyle changes are also important for lupus management. Eating well, exercising often, and adding vitamin D can help your kidneys.9 Sun protection is vital since it can spark flare-ups. This means staying out of the sun, wearing protective clothing, and using high-SPF sunscreen.9 Quitting smoking is a must for lupus patients’ overall health.9

Healthcare teams and patients together create a treatment plan. This plan is personalized to suit each person’s needs. For lupus patients, a mix of meds and lifestyle changes can make a big difference. It helps control symptoms, lowers complication risks, and boosts life quality.

Complications of Lupus

Lupus is a complex autoimmune disease with many complications if not managed. Knowing these risks helps manage the disease better and improves outcomes.

Kidney Damage

Lupus nephritis, or kidney damage, is a big problem for lupus patients.1 About half of them will get it, and it can lead to kidney failure.1 It’s important to spot and treat it early to protect the kidneys.

Neurological Complications

Lupus can inflame the nervous system, causing many issues. This includes headaches, vision problems, seizures, and strokes.10 Early treatment is key to prevent severe disabilities and improve life quality.

Cardiovascular Risks

Lupus also increases heart disease and heart attack risks.1 People with lupus have higher risks of heart attacks and strokes. This is because of inflammation and some medication side effects. Monitoring heart health is crucial for lupus patients.

Early diagnosis and management are vital in reducing complications and improving outcomes.111 Learning about how lupus affects the body helps in making personalized plans with doctors. Together, they can work to lessen long-term risks.

Lupus and Pregnancy

Lupus brings extra challenges for pregnant women or those planning a baby.12 It increases the chance of pregnancy problems, especially for those with certain health issues. These may include high blood pressure or kidney problems.12

12 With lupus, the chance of several pregnancy complications rises. For example, issues like blood clots, high blood pressure, and premature birth are more common.13 Flares happen to about 30% of expecting mothers with lupus, and up to 20% face hypertensive complications.13

13 About 1 in 5 pregnancies with lupus end in miscarriage. Additionally, 1 in 3 women with lupus give birth prematurely.13 Preeclampsia can affect about 1 in every 5 lupus pregnancies.12 Lupus does increase the risk of certain pregnancy issues, but not of having a baby with birth defects.13

12 Taking low-dose aspirin could reduce preeclampsia risk.12 Some babies of lupus mothers get neonatal lupus, showing a rash. Rarely, they might have heart block.12 Most babies, though, are healthy. It’s important to check for certain antibodies in pregnancy to watch for heart problems in the baby.

12 Breastfeeding is usually healthy for both mom and baby. But it’s important to be aware of safe lupus medications during breastfeeding.

Living with Lupus

Living with lupus is a big challenge. This health issue is hard to predict and can really change how you live.14 It’s a condition that doesn’t go away. So, people with lupus will have it for their entire lives.14 Dealing with flare-ups, when symptoms get worse, is very important.

Managing Flare-ups

To handle lupus flare-ups, you might need to change your medications. It’s also important to rest well and stay away from things that might make your symptoms worse, like too much sun.15 Things like overworking, not getting enough sleep, and stress can be bad for people with lupus. So can things like bright lights, getting sick or hurt, and even stopping your lupus medicines.15

It’s good to have a clear plan for your day that includes plenty of breaks. You might also need to get help with chores around the house.14 If your job is too much, you might need to find another job that’s not as stressful, or maybe work fewer hours.14

Support Groups

Support groups are really helpful for people with lupus. They offer a chance to meet others who are dealing with the same issues.15 Being part of a support group not only helps you connect with people who understand but can also help you learn new ways of tackling problems.15

For those with lupus, having friends and family around can make a big difference. Doing things with others, like joining clubs or group therapy, can also help a lot.14

16 Stress triggers Sydney Evans’ lupus. Because of this, she’s had to give up some activities she loves. This includes hiking and making special cakes.16 But by managing her condition and getting support, Sydney’s life has improved. People with lupus can do the same to feel better and take better care of themselves.

Lupus Research and Advancements

Our understanding of lupus and how to treat it has grown a lot. This is due to lupus research and new science. Scientists look at both genes and the environment causing lupus. They also seek better, individualized treatments.17

They want to find it earlier, treat it better, and reduce its lasting effects. Yet, getting diagnosed with lupus in the U.S. takes over six years after symptoms begin.18

Recent studies show some hope. People with lupus might think clearer over time with a certain drug. It’s possible that a new treatment could help people with kidney issues more than others.18

There’s a kind of therapy that might make certain lupus symptoms disappear. It still lets the body respond well to vaccines. Some lupus cases that only affect the skin can make life hard. They affect the mind and how we interact with others a lot.18

We still have a lot to find out about lupus. But, there are signs that things can get better. These efforts in research provide hope for people with lupus. They also give us more insights into this complex disease.17

Lupus Research and AdvancementsKey Findings
Delay in Lupus DiagnosisIn the U.S., there is an average delay of more than six years between the onset of lupus symptoms and the formal diagnosis of systemic lupus erythematosus.18
Cognitive Improvement with AzathioprineA study showed that people with lupus can think better over time with a medicine called azathioprine.18
Voclosporin for Lupus NephritisAfrican Americans with kidney issues from lupus may respond better to a certain treatment. It seems more helpful than other treatments over a long time.18
CD19 CAR-T Cell TherapyA treatment called CD19 CAR-T can make some lupus symptoms go away. It doesn’t stop the body from handling vaccines. This makes it a safe option.18
Cutaneous Lupus and Quality of LifeFor some people, lupus only affects their skin. Yet, it can still have a big impact on life. It affects mental health and how we are with others.18

Though we’re making progress, not all groups get equal chances in lupus studies. Black and American Indian/Alaska Native folks are less often part of these trials. This is not fair. Fixing this would make sure that progress in lupus research helps everyone the same.18

The Lupus Butterfly Rash

The [Lupus butterfly rash] is a red rash shaped like a butterfly’s wings, found on the cheeks and nose bridge.19 Inflammation and sunlight can cause this. They are common triggers for those with lupus.19 Not everyone with lupus gets this rash. But knowing about it helps doctors and patients identify lupus early and start the right treatment.

The [Lupus butterfly rash] is called the malar rash too. About half of people with lupus show this sign early.19 It’s key for doctors to spot lupus. This rash can appear if you are in the sun a lot or feeling stressed. Other signs might be feeling tired, joint pains, and having a fever.19

Besides the butterfly rash, there are other skin issues in lupus, like DLE and SCLE.19 They cause different symptoms. Some show as scaly patches, others as wider rashes on areas exposed to the sun.19 Knowing these signs helps with pinpointing lupus for proper treatment.

Though not everyone gets the [Lupus butterfly rash], it’s still a key sign of lupus.19 Together with other health checks, it aids in diagnosing and managing lupus.19 Patients can then work closely with their doctors to handle skin issues. This can really improve their life and health.

Lupus: A Cruel Mystery

Lupus earns the nickname “cruel mystery” due to its unpredictability. It boasts a wide array of symptoms and causes, making it challenging to diagnose. An estimated 1.5 million Americans live with its effects, finding their lives deeply altered. Even with ongoing research, much about lupus remains unknown.

Over 60% of adults claim to be largely unfamiliar with lupus. Sad stories like Jessica’s, who died at 27 from a lupus-induced heart attack, paint a grim picture. Curtis’ experience, showing symptoms such as confusion and kidney issues, further highlights the disease’s severe impacts.

For the medical world, unlocking lupus’ mysteries remains a top goal. Advancements could lead to better management strategies and support for patients. By understanding lupus’ causes and triggers, health professionals hope to offer more comprehensive care.
