Association between vitiligo and spondyloarthritis.
OBJECTIVE
To establish if spondyloarthritis (SpA) and vitiligo occur together more frequently than by chance.


METHODS
All consecutive patients with SpA seen in a 6 month period were evaluated for vitiligo by an experienced dermatologist. The control group included the 2 consecutive patients without SpA seen after each patient with SpA.


RESULTS
Two hundred thirty-four patients with SpA (131 men, 103 women; mean age 59 +/- 18.3 yrs) were seen in the study period. Of these, 43 had ankylosing spondylitis (AS), 112 psoriatic arthritis (PsA), 14 SpA associated with inflammatory bowel disease, 64 undifferentiated SpA, and one reactive arthritis. The 468 control patients (360 women, 108 men; mean age 68.5 +/- 2 yrs) had various degenerative and inflammatory rheumatic diseases. Eight (3.4%) patients out of 234 with SpA had type A vitiligo. In the control group, 5 (1.06%) out of 468 had type A vitiligo. The difference was statistically significant (p < 0.05). Of the 8 patients with coexisting vitiligo and SpA, 4 had PsA, 2 primary AS, one AS associated with Crohn's disease, and one undifferentiated SpA. Of the 5 patients with vitiligo in the control group, one had rheumatoid arthritis, one S ogren's syndrome, one palindromic rheumatism, one crystal arthropathy, and one osteoarthritis.


CONCLUSIONS
Our results suggest that vitiligo and SpA do not coexist by chance and that vitiligo should be included in the list of diseases associated with SpA.
