COINCIDENT SERONEGATIVE SPONDARTHRITIS - A CASE-REPORT

A patient is described in whom ankylosing spondylitis (AS) and reactiv e arthritis (ReA) coincided. Follow-up five years later showed no prog ression of his AS. He demonstrates that some individuals do have the c apacity to express seronegative spondarthritides in different ways, po ssibly dependent on the infective trigger. The lack of long term effec t of the second disease is both clinically reassuring and theoreticall y intriguing.
