Hyperhidrose bei Acne inversa

Authors: Roth, Nadine;

Hyperhidrose bei Acne inversa

Abstract

The role of sweat glands in hidradenitis suppurativa has been largely neglected, despite the fact that its original designation, as “hidrosadénite phlegmoneuse”, implied an inflammatory malfunction of the apocrine sweat glands as the underlying pathogenic driver. The aim of this study was to evaluate the role of apocrine sweat glands with respect to the proinflammatory environment of hidradenitis suppurativa. Therefore, gravimetric assessment and multiplex cytokine assays from sweat obtained from patients with hidradenitis suppurativa along with immunofluorescence cytokine/chemokine analysis of lesional apocrine glands-bearing hidradenitis suppurativa skin were performed. Gravimetric assessment of 17 patients with hidradenitis suppurativa revealed that the condition is not associated with hyperhidrosis. However, patients seem to be more affected by subjective sweating. The current data identified a complex proinflammatory signature in hidradenitis suppurativa sweat characterized by a significant upregulation of monocyte chemoattractant protein-1, interleukin-8 (CXCL8), and interferon-γ. In agreement with this, a strong in situ expression of these mediators could be observed in apocrine glands of lesional hidradenitis suppurativa skin. These data shed new light on the proinflammatory capacity of apocrine sweat glands in hidradenitis suppurativa, which may lead to reconsideration of the role of sweat glands in hidradenitis suppurativa pathology.

Trotz der ursprünglichen Bezeichnung der Acne inversa als "hidrosadénite phlegmoneuse", die eine inflammatorische Fehlfunktion der apokrinen Schweißdrüsen impliziert, geriet die Rolle der Schweißdrüsen hinsichtlich der Pathogenese der AI in Vergessenheit. Ziel dieser Studie war die Evaluierung der Rolle der Schweißdrüsen im Hinblick auf die für die AI charakteristischen proinflammatorischen Mediatoren. Zu diesem Zweck wurden gravimetrische Schweißmessungen, Multiplex-Zytokin-Assays von Schweißproben, sowie immunfluoreszenzoptische Zytokin-/Chemokin-Untersuchungen von läsionaler AI-Haut durchgeführt. Die gravimetrische Untersuchung von 17 AI-Patienten zeigte, dass AI nicht mit Hyperhidrose assoziiert ist. Allerdings scheinen sich AI-Patienten durch ihr Schwitzen im Vergleich zu einer gesunden Kontrollgruppe subjektiv stärker beeinträchtigt zu fühlen. Unsere Daten zeigen eine komplexe proinflammatorische Signatur im AI-Schweiß, die durch eine signifikant erhöhte Konzentration von Monozyten-Chemoattraktant-Protein-1 (MCP-1), Interleukin-8 (CXCL8) und Interferon-γ gekennzeichnet ist. Passend dazu konnten wir eine erhöhte Expression dieser Mediatoren in apokrinen Schweißdrüsen läsionaler AI-Haut nachweisen. Diese Ergebnisse werfen ein neues Licht auf die proinflammatorische Kapazität apokriner Schweißdrüsen bei AI, was zu einem Überdenken der Rolle der Schweißdrüsen im Hinblick auf die Pathogenese der AI führen kann.
