Abstract

Background: Bariatric surgery (BS) represents the most effective treatment for morbid obesity and its related complications, potentially ameliorating chronic comorbid inflammatory skin conditions, such as psoriasis and hidradenitis suppurativa (HS). Weight-loss interventions are strongly encouraged in patients with HS, but the resulting effect on the course of the disease has been poorly reported. Aim: To describe the effect of BS-associated weight-loss on the course of HS. Methods: This was a retrospective, descriptive study of a hospital-based patient cohort with HS in order to investigate the relationship between exposure to a BS procedure and the HS disease course. Clinical characteristics and BS-related outcomes were retrospectively analysed by chart review for identified cases. Laboratory parameters for selected micronutrients (levels of vitamin A, D and B12, plus zinc and iron) were re-evaluated at a follow-up visit in each post-BS case. Typical patients with HS from the general cohort served as controls for the comparison of vitamin D and zinc serum levels. Results: Of 178 patients with HS, 12 patients with incident HS who had undergone a BS procedure were identified. A subset of patients (n = 10) developed initial signs and symptoms of cutaneous suppuration after experiencing weight loss related to malabsorptive bariatric procedures. Post-BS patients with HS presented multiple micronutritional deficiencies and insufficient responses to standard, first-line antibiotic treatments. Of the micronutrients we selected for analysis, zinc was found to be at significantly lower serum levels in post-BS patients with HS compared with typical patients with HS. Conclusions: Post-BS HS may represent a new patient subset, requiring customized clinical management.
