Hidradenitis suppurativa and polycystic ovarian syndrome: Systematic review and meta-analysis
Abstract
BACKGROUND/OBJECTIVES: Hidradenitis suppurativa has been associated with a number of pathologies, including various endocrine and autoimmune disorders. Although signs of hyperandrogenism are common in hidradenitis suppurativa, few formal studies have assessed the relationship between hidradenitis suppurativa and polycystic ovarian syndrome. Therefore, we performed a systematic review and meta-analysis to assess the association between hidradenitis suppurativa and polycystic ovarian syndrome.
METHODS: We performed a systematic review and meta-analysis according to PRISMA guidelines. Odds ratio was used as the effect size, with random-effects meta-analysis.
RESULTS: We identified five case-control studies for inclusion. From pooled data, we found a significantly higher proportion of polycystic ovarian syndrome in hidradenitis suppurativa cases compared with controls (OR 2.64; 95% CI 1.69-4.11; P < 0.00001). There was significant heterogeneity noted (I2 = 88%, P < 0.00001). Limitations included that studies reviewed were observational by design which are susceptible to bias, and lack of randomisation.
CONCLUSIONS: In summary, pooled analysis of existing case-control studies supports a significant association between hidradenitis suppurativa and polycystic ovarian syndrome. Our results imply that hidradenitis suppurativa patients with signs of hyperandrogenism may benefit from screening for polycystic ovarian syndrome, and may potentially benefit from anti-androgen therapy.
