Demographic characteristics are known to influence the efficacy and drug survival of hidradenitis suppurativa therapeutics including biologic therapies. What remains unknown is the impact of ethnicity upon the efficacy of therapeutics once demographic and disease characteristics have been taken into account. This is an important question given the expansion of biologic therapies for HS into the global patient community.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We assessed 170 patients from a single HS specialist centre in Australia stratified by patient\u2010identified ethnicity including those identifying as either Caucasian or Asian.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Asian patients demonstrated lower BMI, higher rates of smoking and greater odds of Hurley stage 3 disease with tunnels than Caucasian patients in line with the reported literature.

Significant differences were seen in median time to secondary loss of response, and Kaplan\u2013Meier curve analysis showed a significant difference between curves when stratified by patient\u2010reported ethnicity.
