Riis PT, et al. - A comparative scrutiny was performed of the Hidradenitis suppurativa (HS) patients with a high body mass index (BMI) with HS patients with a low BMI. The intent was to gauge the variations in disease characteristics. The data unveiled that patients with a low and high body mass index could represent two clinically different subtypes. A non-linear association between BMI and the effect of HS was brought to light. As patients shift from a low BMI patient to a high BMI patient (or from high to low), eruption patterns and risk factors could change.
