May is Lupus Awareness Month.
Lupus is an autoimmune disease that happens when the body’s immune system attacks its own tissues and causes harmful inflammation.
About 1.5 million Americans are living with some form of lupus.
9 out 10 people with lupus are women.
Common types of lupus
Systemic lupus erythematosus (SLE)
SLE is the most common type of lupus. When people mention lupus, they usually mean SLE.
In the U.S., SLE is:
3x more common in Black and Native American people
2x times more common in Hispanic people
SLE can affect many parts of the body, including:
Heart
Lungs
Skin
Kidneys
Joints
Brain
Some symptoms of SLE are:
Fatigue
Fever
Joint pain, swelling, or stiffness
Scaly rash
Hair loss
Mouth or nose sores
Swelling around eyes or in legs
Foamy urine
Painful breathing
Fingers turning colors in the cold
Kidney inflammation caused by SLE can damage the kidneys, leading to a condition called lupus nephritis.
Cutaneous lupus (CLE)
Happens when the immune system attacks the skin, causing rashes that may be red or scaly.
About 65% of people with SLE will develop CLE.
Symptoms of CLE include:
Red, scaly patches that are sometimes round and outlined by a darker red ring
Butterfly rash (rash across the cheeks and over the bridge of the nose)
Drug-induced lupus
Happens when certain medications trigger an autoimmune disorder similar to SLE.
Medications most often linked to drug-induced lupus:
Hydralazine (for high blood pressure)
Procainamide (for irregular heart rhythm)
Quinidine (for irregular heart rhythm)
Symptoms of drug-induced lupus are similar to those of SLE.
It often takes months or years of using the medication for these symptoms to develop.
Symptoms typically go away within 6 months of stopping the medication.
Neonatal lupus
Happens when a pregnant person passes certain antibodies to the fetus.
These antibodies attack healthy tissue in the fetus, causing lupus-like symptoms in the newborn.
The most common symptom:
Skin rash that looks like reddish rings with a normal-colored center
Symptoms usually clear up within a year, but in rare cases, neonatal lupus can affect the baby’s heart, preventing it from beating properly.
This is called autoimmune congenital heart block. It is a serious condition but is treatable with a pacemaker.
Shedding light on a complex condition
Lupus is complicated, but it can be managed.
