What is Systemic Lupus Erythematosus?

Systemic lupus erythematosus (SLE) is an autoimmune disease that occurs when your body’s immune system attacks your own tissues and organs. The inflammation can affect numerous body systems, from your joints to your lungs. It can be a challenging disease to diagnose as its signs and symptoms mimic those of other ailments.

It’s believed that lupus is caused by your genetics and your environment. Some people are born with a tendency towards developing lupus. It may be triggered by certain drugs, sunlight or infections.

  • Fatigue
  • Mouth ulcers
  • Swollen lymph nodes
  • Hair loss
  • Muscle pain
  • Swelling of the legs or eyes

Causes of Lupus

Lupus is an autoimmune disease that occurs when the body’s immune system starts to attack itself, leading to inflammation.

The word “inflammation” comes from the Latin word “inflammare” which means to light on fire.

Nerve Tests

If your rheumatologist thinks it could be beneficial, he or she may recommend electromyography or nerve conduction studies to look for nerve involvement.

Blood Tests to Diagnose Lupus

There are a number of blood tests that can help diagnose lupus:

Anti-nuclear antibody (ANA) test: This important test looks for antibodies that attack the body. If this test comes back negative, then it’s generally believed that they don’t have lupus. If it comes back positive, your rheumatologist may prescribe more tests to confirm lupus.

Anti-Double Stranded DNA (anti-dsDNA) test: Your rheumatologist can measure antibodies that attack DNA with this very specific test for lupus.

Extractable Nuclear Antigen (ENA) panel: The antibodies in this panel may include anti-Ro (also called anti-SSA), anti-La (also called anti-SSB), anti-Sm, anti-RNP, anti-Jo-1, anti-Scl70, and anti-centromere. This test looks for antibodies that attack certain proteins.

Complete Blood Count (CBC): Because lupus can cause inflammation, this blood test can detect abnormal results.

Creatinine: If you have abnormally high levels of creatinine, this can indicate a problem with how your kidneys are functioning.

Diagnosis of Lupus

To properly diagnose systemic lupus erythematosus,  you should see a rheumatologist, a type of physician who specializes in arthritis and autoimmune disease.

To diagnose lupus, your physician will take your complete medical history, perform a complete physical examination and order blood tests.

Urine Tests

In addition to blood tests, your physician may recommend urinalysis testing to detect protein or blood in the urine that may indicate your kidneys are involved.

Scans

In addition to other types of testing, your rheumatologist may prescribe a chest x-ray and/or CT scans can help confirm if the lungs are involved in lupus.
