Spondyloarthritis Risk Significantly Higher in HS Patients

Hidradenitis suppurativa (HS) is significantly associated with an increased risk of spondyloarthritis, according to the results of a recent study.

The researchers performed a single-center, cross-sectional study of 39 patients with HS and 39 healthy participants without dermatological disease, matched by age and gender. HLS-B27 testing and sacro-iliac MRI were performed in each participant to diagnose spondyloarthritis according to the Assessment of SpondyloArthritis international Society (ASAS) criteria.

Overall, 11 (28.2%) patients in the HS group and 1 in the control group were diagnosed with spondyloarthritis. Axial spondyloarthritis was most common, observed in 9 of the 11 patients in the HS group.

“Our results indicate that HS is significantly associated with an increased risk of spondyloarthritis, independently of age and sex. Patients with HS presenting osteoarticular symptoms, specially low back pain or dactylitis, should be monitored for spondyloarthritis,” the researchers concluded.
