It is not known fully. But scientists have found that a Psoriasis immune system & genes play an important role There are many triggering factors –
• A STRESSFUL EVENT
• SORE THROAT
• SOME MEDICINES
• COLD DRY WEATHER
Psoriasis is a skin disorder driven by the immune system, especially involving a type of white blood cell called a T cell. Normally, T cells help protect the body against infection and disease. In the case of psoriasis, T cells are put into action by mistake and become so active that they trigger other immune responses, which lead to inflammation and to rapid turnover of skin cells.
Some people carry genes, which make them more prone to develop psoriasis. Those who already have psoriasis in the family carry these genes on chromosome 6, others on chromosome 8.
The following can also trigger off psoriasis -
- Emotional stress
- Injury to the skin
- Streptococcal throat infection
- Drugs e.g. anti-malarials like chloroquine and mefloquine, blood pressure lowering agents like beta-blockers, calcium channel blockers and captopril, painkillers like aspirin, cholesterol lowering agents like gemfibrozil, psychiatric medicines like lithium, systemic steroids and alcohol intake.
