• Immune System usually defends Immune System usually defends against bacterial or viral invaders against bacterial or viral invaders and plays a key role in controlling and plays a key role in controlling the growth of cancer cells.the growth of cancer cells.

• 2 components of the immune 2 components of the immune response:response:

SLE- LupusSLE- Lupus

• Primarily disease of young women. • Peak incidence occurs between ages 15-40,

during childbearing years• Female-to- male ratio 10:1• Young black women majority group affected• Once considered fatal, now 85% of patients live

longer than 15 years after diagnosis• Most common causes of death: active lupus

nephritis, vascular events and infections

Lupus- Pathophysiology Lupus- Pathophysiology

• Exaggerated production of autoantibodies

• Combination of genetic, hormonal & environmental factors ?

• Drug-induced lupus– Apresoline, procainamide, INH, Thorazine,

some anti-seizure meds• Abnormal suppressor T-cell function• Immune complex deposits cause tissue

damage• Inflammation stimulates antigens, which

in turn stimulates additional antibodies • Sx can flare

• Persons with lupus need to adjust their diet to help with hypertension and renal failure

• Reduce salt and fat intake• Reduce cholesterol intake• Also important to stop smoking to

reduce the risk of hypertension and coronary artery disease
