The aetiology of rheumatoid arthritis is multifactorial. It is thought to be caused by an interaction among genetic susceptibility and environmental triggers (1).
- 60% of a population's predisposition to RA is genetically determined
- environmental contribution is not clear although various infective agents have been proposed
- hormonal influences may also exist.
