Dermatologische unerwünschte Arzneimittelwirkungen bei Behandlung mit Biologika – Pathogenese und Management

Biologika sind für verschiedene Entzündungskrankheiten aus Dermatologie, Allergologie, Rheumatologie und Gastroenterologie sowie für zahlreiche maligne Erkrankungen zugelassen. Dermatologische unerwünschte Arzneimittelwirkungen durch Biologika können primären entzündlichen Dermatosen ähneln, unterscheiden sich von ihnen jedoch in ihrer Pathogenese. In diesem Artikel beschreiben wir die fünf verschiedenen Pathomechanismen dermatologischer, unerwünschter Arzneimittelwirkungen durch Biologika. Durch besseres Verständnis dieser Mechanismen erhoffen wir uns wertvolle Einblicke in die Pathogenese primärer Entzündungskrankheiten zu gewinnen. Außerdem geben wir in diesem Artikel Empfehlungen für die Behandlung und das Management der durch Biologika ausgelösten dermatologischen unerwünschten Arzneimittelwirkungen.

Dermatologic adverse events caused by biologic treatments - Pathogenesis and management

Biologics are approved for various dermatologic, allergic, rheumatic, and gastroenterologic inflammatory diseases, as well as for numerous malignancies. The dermatologic adverse events from treatment with biologics may resemble primary inflammatory diseases but differ in pathogenesis. In this article, we describe five different pathogenic mechanisms of dermatologic adverse events. By studying these mechanisms, we hope to gain valuable insights into the pathogenesis of primary inflammatory diseases. In addition, in this article, we provide recommendations for the treatment and management of the dermatological adverse events induced by biologics.

Case Report: sintilimab-induced Stevens-Johnson Syndrome in a patient with advanced lung adenocarcinoma

Immune checkpoint inhibitors (ICIs) have been widely applicated in clinical therapy in recent years. Skin-related adverse reaction is one of the most common adverse events for ICIs. Stevens-Johnson syndrome (SJS) is one of the serious cutaneous reactions threatening the life. Here, we reported a case of 76-year-old male patient with poorly differentiated metastatic lung adenocarcinoma, after 9 weeks exposure of sintilimab (3 doses) combined with paclitaxel liposome after concurrent chemotherapy/radiotherapy, experienced Stevens-Johnson syndrome involving limbs, trunk, lip and the oral mucosa. Biopsy of the skin tissue showed infiltration of CD4 and CD8 positive T lymphocytes. We also found PD-L1 expression in the glands and the basal layer of the skin. This finding is distinct from the previously reported expression of PD-L1 on the surface of epidermal keratinocytes in patients with SJS due to immunotherapy.
