Early Pathophysiology of Hidradenitis Suppurativa and Prediction of the Risk of Progression: a Prospective Cohort (Early-HS)
Physiopathologie précoce de l'hidradénite suppurée et prédiction du Risque de Progression : Cohorte Prospective
Hidradenitis suppurativa (HS) is a chronic inflammatory disease affecting approximately 1% of the population. Most pathophysiological studies have focused on advanced forms (Hurley II-III), which obscures the initial mechanisms. The mean diagnostic delay of 7 to 10 years and the lack of prognostic biomarkers limit early management. Identifying molecular and microbiological alterations as early as Hurley stage I could allow stratification of the risk of progression and support early intervention strategies.

Patient-reported score - Dermatology Life Quality Index
時間枠:Up to 96 months
|
The Dermatology Life Quality Index (DLQI) total score ranges from 0 to 30, with higher scores indicating a greater negative impact of the skin disease on quality of life (0-1: no effect; 2-5: small effect; 6-10: moderate effect; 11-20: very large effect; 21-30: extremely large effect). The Children's Dermatology Life Quality Index (CDLQI) total score ranges from 0 to 30, with higher scores indicating a greater negative impact of the skin disease on the child's quality of life. |
