<b><i>Background:</i></b> Several studies report a high prevalence of inflammatory arthritis among hidradenitis suppurativa (HS) patients. <b><i>Objectives:</i></b> To study the association between HS and inflammatory arthritis. <b><i>Methods:</i></b> The systematic review and meta-analysis were performed according to the PRISMA guidelines to identify the association between HS and inflammatory arthritis, spondyloarthritis, ankylosing spondylitis (AS), and rheumatoid arthritis (RA). <b><i>Results:</i></b> Seven studies were entered in the analysis, with 200,361 HS patients and 385,599 controls. Pooled analysis illustrated a significantly increased risk of inflammatory arthritis in HS patients compared to controls (odds ratio [OR] 3.44; 95% confidence interval [CI] 1.92–6.17). There was also a statistically significant association between HS and spondyloarthritis (OR 2.10; 95% CI 1.40–3.15), and between HS and AS (OR 1.89; 95% CI 1.14–3.12). Moreover, pooled analysis showed a statistically significant association between HS and RA (OR 1.96; 95% CI 1.28–2.98). <b><i>Conclusions:</i></b> Our findings show that HS patients have a 3-fold increased risk of developing inflammatory arthritis. HS patients are specifically at a higher risk for spondyloarthritis, its subtype AS, and RA.

Abstract Background There is a significant variation in the reported prevalence of hidradenitis suppurativa (HS), ranging from 0.03–4%. We hypothesized that this significant variation may be due to different prevalence rates of HS according to geographical location as well as sex. Objective We aimed to perform a meta-analysis to determine pooled overall prevalence of HS, prevalence stratified according to geographical region and sex. Materials and methods A systematic review was performed by searching Ovid Medline, PubMed, Cochrane Library, DARE, and Embase, from inception to August 2018. A systematic review and meta-analysis was performed according to PRISMA guidelines. A meta-analysis of proportions was performed to determined pooled prevalence rates, with meta-regression based on geographic region. Prevalence in males versus females was also performed according to region. Results The overall pooled prevalence rate was 0.3% (0.2–0.6%) based on 118,760,093 HS cases available. Subgroup analysis demonstrated prevalence differences, with the highest being in Europe 0.8% (0.5–1.3%), compared to the USA 0.2% (0.1–0.4%), Asia-Pacific 0.2% (0.01–2.2%), and South America 0.2% (0.01–0.9%). Prevalence in males was lower compared to females in the USA (OR 0.403, 95% CI 0.37–0.439, P < 0.001) as well as in Europe (OR 0.635, 95% CI 0.397–1.015, P = 0.08) but not in the Asia-Pacific region (OR 0.936, 95% CI 0.319–2.751, P = 0.78). Conclusion Prevalence of HS varies significantly according to the geographical population. This variation is likely attributed to different ethnicity distributions amongst different continents.

Abstract Background Hidradenitis suppurativa (HS) is a chronic inflammatory skin disorder which involves painful nodules and draining abscesses in flexural areas. Acne vulgaris and its more severe variants including acne conglobata and acne fulminans are also disorders involving the follicular unit. Given that follicular obstruction, dilatation and inflammation feature in both HS and acne vulgaris/conglobata, it has been suggested that HS is associated with acne vulgaris/conglobata. Methods The present systematic review and meta-analysis was performed according to recommended PRISMA guidelines. All eligible case-control studies comparing patients with HS vs non-HS were included in the present review. All studies must have included either the proportion of patients with acne vulgaris/conglobata in each group, or the summary effect size for association between HS and acne vulgaris/conglobata. The odds ratio (OR) was used as a summary statistic. Results From pooled unadjusted meta-analysis, we found a significantly higher proportion of patients with acne vulgaris/conglobata in HS cases compared to controls (OR 3.44, 95% CI 1.95–6.07, P < 0.0001, I2 = 100%). Pooled meta-analysis was also performed with adjusted effect sizes. This demonstrated that HS was significantly associated with acne vulgaris/conglobata after adjustment for potential confounders (OR 3.44, 95% CI 2.43–4.87, P < 0.00001, I2 = 99%). Conclusions In summary, a significant association was found between HS and acne vulgaris/conglobata. This has implications in terms of understanding the burden of disease on patient quality of life as well as consideration of optimal management strategies to target both disorders. Physicians taking care of patients with HS should be aware of this association.
