Skin manifestations after immunisation with an adjuvanted recombinant zoster vaccine, Germany, 2020.

BackgroundShortly after the launch of a novel adjuvanted recombinant zoster vaccine (RZV), Shingrix, cases of suspected herpes zoster (HZ) or zoster-like skin reactions following immunisation were reported.AimWe aimed to investigate if these skin manifestations after administration of RZV could be HZ.MethodsBetween April and October 2020, general practitioners (GP) reporting a suspected case of HZ or zoster-like skin manifestation after RZV vaccination to the Paul-Ehrlich-Institut, the German national competent authority, were invited to participate in the study.

Case report: Generalized bullous fixed drug eruption mimicking epidermal necrolysis.

Generalized bullous fixed drug eruption (GBFDE) is the most severe form of fixed drug eruption and can be misdiagnosed as epidermal necrolysis (EN). We report the case of a 42-year-old male patient presenting with more than 50% skin detachment without defined areas of exanthema or erythema and a history of one prior event of EN caused by acetaminophen (paracetamol), allopurinol, or amoxicillin 1.5 years ago.

[Severe cutaneous drug reactions in children].

Severe cutaneous drug reactions also occur in children and range from reactions with blister forming of skin and mucosa to extensive exanthems with altered differential blood count and involvement of internal organs. The first group includes Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), which are considered as one disease entity with different degrees of severity and are also referred to as "epidermal" or "epithelial necrolysis" (EN). The group of drug reactions with primarily systemic alterations is represented by a condition known as drug reaction with eosinophilia and systemic symptoms (DRESS).

Effects of dosage in new users of lamotrigine inducing epidermal necrolysis: Results of the German Registry of Severe Skin Reactions.

Objective: This study was undertaken to determine the impact of dosage in new users of lamotrigine (LTG) and the concomitant intake of valproic acid (VPA) on epidermal necrolysis (EN).

Methods: A total of 102 EN cases with exposure to LTG were identified (1992-2018) in the German Registry of Severe Skin Reactions. All cases are validated by an independent expert committee.

Updates on the immunopathology and genomics of severe cutaneous adverse drug reactions.

Severe cutaneous adverse reactions (SCARs) such as Stevens-Johnson syndrome, toxic epidermal necrolysis (SJS/TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS)/drug-induced hypersensitivity syndrome (DIHS) cause significant morbidity and mortality and impede new drug development. HLA class I associations with SJS/TEN and drug reaction with eosinophilia and systemic symptoms/drug-induced hypersensitivity syndrome have aided preventive efforts and provided insights into immunopathogenesis. In SJS/TEN, HLA class I-restricted oligoclonal CD8 T-cell responses occur at the tissue level.

Transmission characteristics, replication patterns and clinical manifestations of human monkeypox virus-an in-depth analysis of four cases from Germany.

Objective: Since April 2022, increasing numbers of monkeypox (MPX) cases have been reported outside endemic areas as part of an international outbreak. Our study shows aspects of clinical manifestations as well as epidemiological and virological features impacting transmission, for which only scarce data are available so far.

Methods: We present a descriptive study consisting of epidemiological, clinical and virological data of four patients with confirmed MPX diagnosis.

Unmet Educational Needs and Clinical Practice Gaps in the Management of Generalized Pustular Psoriasis: Global Perspectives from the Front Line.

Introduction: Generalized pustular psoriasis (GPP) is a rare, potentially life-threatening, neutrophilic, autoinflammatory skin disease characterised by recurrent flares of generalised sterile pustules and associated systemic features. Inconsistent diagnostic criteria and a lack of approved therapies pose serious challenges to GPP management. Our objectives were to discuss the challenges encountered in the care of patients with GPP and identify healthcare provider (HCP) educational needs and clinical practice gaps in GPP management.

Drug Allergy and Cutaneous Adverse Reactions.

Allergy or hypersensitivity to drugs often affects the skin and sometimes also mucosa. While immediate type reactions show a rather homogeneous pattern, delayed type reactions reveal a high variability. In both cases it may not always be easy to differentiate drug reactions from non-drug-induced skin conditions.

[Ocular involvement in Stevens-Johnson syndrome and toxic epidermal necrolysis].

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare severe and often life-threatening reactions of the skin and mucous membranes. They are considered as a single disease entity with different expressions of severity and are summarized under the term epidermal necrolysis (EN). There is a high risk of ocular involvement, which can lead to long-lasting eye problems and even blindness without immediate ophthalmological treatment.
