LUPUS Facts symptoms, Rash and Effects

  • Brain and Spinal Cord. Brain involvement is, fortunately, a rare problem in people with lupus. When present, it may cause confusion, depression, seizures, and, rarely, strokes. Involvement of the spinal cord (transverse myelitis) can cause numbness and weakness.
  • Heart and Lungs. Heart and lung involvement often is caused by inflammation of the covering of the heart (pericardium) and lungs (pleura). When these structures become inflamed, patients may develop chest pain, irregular heartbeat, and accumulation of fluid around the lungs (pleuritis or pleurisy) and heart (pericarditis). The heart valves and the lung itself can also be affected by lupus, resulting in shortness of breath.

What Causes Lupus?

The cause of lupus is unknown. However, there appears to be something that triggers the immune system to attack various areas of the body. That’s why suppressing the immune system is one of the main forms of treatment. Finding the cause is the object of major research efforts.

Factors that may contribute to the development of lupus include viruses, environmental chemicals and a person’s genetic makeup.

Female hormones are believed to play a role in the development of lupus because women are affected by lupus much more often than men. This is especially true of women during their reproductive years, a time when hormone levels are highest.

The observation that lupus may affect more than one member of the same family has raised the possibility that the tendency to develop lupus may be inherited. Having such a tendency, however, does not predict that a relative will develop lupus. Only about 10% of people with lupus have a close relative with the disease.

Drug-induced lupus can occur after the use of some prescription medications (such as hydralazine and procainamide). These symptoms generally improve after the drug is discontinued.
