Proteins in the blood that react with the nuclei of cells. The ANA test measures the pattern and amount of autoantibodies, which can attack the body’s tissues as if they were foreign material. Positive ANA tests are seen in 96 percent of systemic lupus erythematosus patients and in 5 percent of healthy patients.
Antinuclear Antibodies (ANA)
Antibodies often directed against cardiolipin and found in several diseases including syphilis, antiphospholipid syndrome and systemic lupus erythematosus.
Anti-Cardiolipin Antibodies (ACA)
A means of detecting antiphospholipid antibodies from prolonged clotting times.
Drugs originally designed to prevent or cure malaria, but they’re also used in the treatment of lupus, including Plaquenil (Hydroxychloroquine).
These antibodies are present in one-third of those with SLE. They can alter clotting and lead to strokes, blood clots, miscarriages and low platelet counts.
Present in SLE and mixed connective tissue disease.
Antibodies that are found almost exclusively in lupus patients.
These antibodies are associated with Sjogren’s syndrome, sun sensitivity, neonatal lupus and congenital heart block.
Anti-SSA (aka Ro antibodies)
Swollen or tender joints, arthritis is usually found in two or more joints in lupus patients.
The failure of an organism to recognize its own constituent parts as self, which allows an immune response against its own cells and tissues. Any disease that results from such an abnormal immune response is termed an autoimmune disease.
A long-lasting (typically more than three months) or recurrent disease. The term chronic describes the course of the disease, or its rate of onset and development. As an adjective, chronic can refer to a persistent and lasting medical condition.
Medical specialists who study resistance to infections and diseases. Immune reactions are studied to determine ways to boost the immune system to fight against harmful micro-organisms.
These drugs, including prednisone, act on the immune system by blocking the production of substances that trigger allergic and inflammatory actions.
A blood protein. Raised levels reflect inflammation, which might have many different causes including infections or autoimmune disease, among others.
CRP (C-Reactive Protein)
A medical doctor who specializes in the diagnoses and treatments of conditions associated with skin, hair and nails.
A drug that works to produce more urine.
A milder form of lupus because it only affects the skin. Discoid lupus is characterized by red, scaly, inflamed, coin-shaped (discoid) lesions, which are dark on the outside and light on the inside. They show up mainly on the face, but can appear on any part of the body. Discoid lupus can progress to the more serious systemic lupus erythematosus (SLE) in about 10 percent of patients.
Discoid (Cutaneous) Lupus
Red, raised, scaly, disk shaped patches usually found on areas that have been exposed to the sun. They show up mainly on the face, but can appear on any part of the body.
An autoimmune disorder caused by chronic use of certain drugs. These drugs cause an autoimmune response (the body attacks its own cells) producing symptoms similar to those of SLE. There are at least 46 medications known to cause DIL, but there are three that report the highest number of cases: hydralazine, procainamide and isoniazid. While the criteria for diagnosing DIL has not been thoroughly established, symptoms of DIL typically present as myalgia and arthralgia. Generally, the symptoms recede after discontinuing use of the drugs.
Drug-Induced Lupus (DIL)
A pain amplification syndrome characterized by fatigue and tender joints in the soft tissues.
When lupus symptoms appear, it’s called a “flare.” These signs may come and go. Even if a person takes medicine for lupus, he or she may find there are times when the symptoms become worse. Learning to recognize that a flare is coming can help you take steps to cope with it. Just before a flare, many people with lupus feel very tired, have pain, a rash, fever, stomach discomfort, headaches and/or feel dizzy.
Inflammation of the glomerulus of the kidney. It affects about one-third of lupus patients.
Hemolytic anemia (low red blood cell count), leucopenia (low white blood cell count) or thrombocytopenia (low platelet count).
A medical doctor who specializes in the diagnoses and treatments of conditions associated with the blood system.
A major antibody of plasma and an important part of the antibody response. Most autoimmune diseases are characterized by IgG antibodies.
IgG (Immunoglobulin G)
One of many diagnostic criteria for lupus, identified by blood tests that show anti-double stranded DNA, anti-SM, antiphospholipid antibody, anti-RNA, anti-Ro, anti-LA or false positive syphilis test.
A class of medications used to treat lupus by suppressing the immune system, including Azathioprine and Cyclophosphamide.
Swelling, heat and redness that results from the infiltration of white blood cells in the tissues.
A change in tissue due to injury or disease.
Low white blood cell count.
Inflammation of subcutaneous fat.
Lupus Erythematosus Profundus
Rash shaped like a butterfly over the cheeks and nose. This rash commonly extends from one cheek over the nose to the other cheek. The rash was named lupus because early physicians believed the rash looked a lot like the bite of a wolf (lupus is the Latin word for wolf).
An uncommon autoimmune disorder that is characterized by overlapping features of primarily three connective tissue diseases — lupus, scleroderma and polymyositis.
Mixed Connective Tissue Disease
Inflammation of the heart.
In rare cases, the newborn of a mom with lupus or another autoimmune disorder may have neonatal lupus. This condition can cause skin rashes, anemia or liver problems. Symptoms usually go away after a few months and don’t cause permanent damage. Some babies with neonatal lupus are born with a serious heart defect.
Inflammation of the kidney.
A medical doctor who specializes in the diagnoses and treatments of kidney diseases.
Nonsteriodal anti-inflammatory drugs that fight inflammation, treat pain and address fever.
Seizures (convulsions) and/or psychosis with no other explanation.
A medical doctor who specializes in the diagnoses and treatments of diseases associated with the brain, spinal cord, spinal column, peripheral nerves and nervous system.
Non-Steroidal Anti-Inflammatory Drugs (NSAIDs or NAIDs)
NSAIDs reduce inflammation and relieve fever and pain by blocking enzymes and proteins made by the body. The term “nonsteroidal” distinguishes these drugs from those which contain steroids. Examples of NSAIDs include Aspirin, Ibuprofen, Naproxen, Daypro and Lodine.
Sores in the nose or mouth.
Excess fluid around the heart sac.
Inflammation of the pericardium (the sac lining the heart).
Inflammation of a vein.
Reaction to sunlight, which causes skin rashes.
Excess fluid in the sac lining of the lung.
Irritation or inflammation of the lining of the lung.
A general practitioner who provides continuous medical care. They’re trained to treat a wide array of health related problems and are responsible for referral to specialists as needed.
Excess protein levels in the urine.
Elevated blood pressure in the lungs.
One of many diagnostic criteria for lupus, identified by excessive protein and cell casts (abnormal sediment) found in urine.
Discoloration of the hands or feet (turn blue, white or red) with cold temperatures can occur in some patients with autoimmune disease.
Chronic disease of the joints marked by inflammatory changes in the joint-lining membranes, which may give positive results on rheumatoid factors and ANA tests.
Rheumatoid Arthritis (RA)
A medical doctor who specializes in the diagnoses and treatments of autoimmune and joint diseases.
Inflammation of the linings (serosa) of organs, usually pleurisy (lung), pericarditis (heart) or peritonitis (abdominal).
An autoimmune disorder with dry eyes and dry mouth as the most common symptoms. Can occur in patients with other autoimmune disorders.
A rash, often circular and distributed on the chest, neck and upper arms. It’s sometimes seen in patients whose blood tests are negative. Patients are very sensitive to UV light.
Sub-Acute Cutaneous Lupus Erythematosus (SCLE)
Inflammation of the tissues lining the joints.
SLE is typically the most common form of lupus and is generally considered more serious than the other three forms. SLE can affect many parts of a person’s body, including kidneys, heart, lungs, brain, blood and skin. Symptoms tend to vary among patients and can change often and suddenly. Lupus can follow an unpredictable pattern of remissions (symptoms disappear) and flares (active symptoms).
Systemic Lupus Erythematosus (SLE)
Kidney deficiency, which frequently requires dialysis.
Inflammation of blood vessels.
