What causes psoriatic arthritis?
Doctors don't know the exact cause of psoriatic arthritis. But it's linked to problems with the body’s infection-fighting system (immune system). Other factors include:

Family history. People who have psoriatic arthritis often have relatives with either psoriasis or arthritis, or both. 
- 
Certain infections. These include strep infections and HIV. 
- 
Environment. Stress, injury to skin, and certain medicines may trigger psoriasis to become active.
