Back Pain and Axial Spondyloarthropathy association with Hidradenitis Suppurativa

Hidradenitis suppurativa (HS), sometimes known as acne inversa, is a painful, long-term skin disease that causes abscesses and scarring on the skin usually around the groin, buttocks, breasts and armpits.

Many other chronic inflammatory diseases are frequently linked with spondyloarthropathies (SpA). A study has been done to quantify the prevalence of back pain and SpA in hidradenitis suppurativa patients. Questionnaire survey was done in around 100 HS patients and a retrospective evaluation of pelvic magnetic resonance imaging (MRI) scans in 46 HS patients.

Results showed that about 71% of subjects had back pain. It was observed that there was no difference between age at onset of HS, disease duration, body mass index (BMI), or disease severity between HS patients with and without back pain. Pelvic MRI scans were evaluated and found signs of chronic SpA in 32.6% in HS patients and signs of active SpA 39.1% in HS patients.

No significant differences were found between the patients with/without SpA regarding age at time of MRI, age at onset of HS, disease duration, smoking habits, and BMI. Furthermore, there was no correlation between these parameters and degree of SpA. But, one limitation in this study was that patients with moderate/severe HS in genitofemoral/perianal sites were analysed via MRI scans.

The researchers noted that back pain and SpA are very common seen in patients with moderate/severe HS. Therefore, neither medical history nor clinical parameters indicates the presence of SpA.
