Abstract
BACKGROUND: Hidradenitis suppurativa (HS) is a chronic, debilitating, heterogeneous disease requiring different treatment approaches. Recently, we refined the classic Hurley classification into a seven-stage classification in order to guide these treatment choices. This new classification subdivides Hurley stage I and II into three sub-stages namely mild (A), moderate (B), and severe (C) HS disease. Hurley stage III is not sub-categorised and always severe.
AIM: To investigate the correlation between the given severity grades of Hurley I and Hurley II in the refined Hurley classification, and the patient reported quality of life and physician-assessed objective severity score.
METHODS: In this cross-sectional study, HS patients participating in the observational cohorts of two Dutch tertiary referral centres were included before June 2017. The patient reported Dermatology Life Quality Index (DLQI) and physician-assessed International HS Severity Score System (IHS4) scores were compared between the refined Hurley stages.
RESULTS: In total, 433 patients were analysed. DLQI and IHS4 scores increased within Hurley stage I and II from A through C. There was a significant positive correlation of DLQI and IHS4 with increasing refined Hurley sub-stages (refined Hurley stage I (A, B, and C) to DLQI: rs =0.259, p<0.001 and refined Hurley stage II (A, B, and C) to DLQI rs =0.185, p=0.010; refined Hurley stage I (A, B, and C) to IHS4 rs =0.603, p<0.001 and refined Hurley stage II (A, B, and C) to IHS4 rs =0.532, p<0.001).
CONCLUSION: The refined Hurley classification accurately correlates with HS severity assessed by both patients and clinicians. Therefore, the refined Hurley classification is a useful tool for the quick assessment of severity in HS. This article is protected by copyright. All rights reserved.
