Symptoms vary from person to person, and may come and go. The condition may affect one organ or body system at first. Others may become involved later. Almost all people with SLE have joint pain and most develop arthritis. Frequently affected joints are the fingers, hands, wrists, and knees.

Inflammation of various parts of the heart may occur as pericarditis, endocarditis, or myocarditis. Chest pain and arrhythmias may result from these conditions.

General symptoms include:

• Fever
• Fatigue
• General discomfort, uneasiness or ill feeling (malaise)
• Skin rash - a "butterfly" rash over the cheeks and bridge of the nose affects about half of those with SLE. The rash gets worse when in sunlight. The rash may also be widespread.
• Sensitivity to sunlight
• Joint pain and swelling
• Arthritis
• Swollen glands
• Muscle aches
• Nausea and vomiting
• Pleurisy (causes chest pain)
• Pleural effusions
• Seizures
• Psychosis

The diagnosis of SLE is based upon the presence of at least four out of eleven typical characteristics of the disease. The doctor will listen to your chest with a stethoscope. A sound called a heart friction rub or pleural friction rub may be heard. A neurological exam will also be performed.

Tests used to diagnose SLE may include:

• Antinuclear antibody (ANA) panel including anti-DNA and anti-Smith antibodies
• Chest x-ray showing pleuritis or pericarditis
• Urinalysis to show blood, casts , or protein in the urine
• CBC
• Kidney biopsy

This disease may also alter the results of the following tests:

• WBC count
• Serum globulin electrophoresis
• Rheumatoid factor
• Urine protein
• Serum protein electrophoresis
• Mononucleosis spot test
• ESR
• Cryoglobulins
• Coombs' test - direct
• Complement component 3 (C3)
