Background: Approximately 10% of European children are classified as allergic to drugs. In the majority of these children, no allergy to β-lactam antibiotics (BLA) can be found. In most cases, the exanthema is caused by the infection. Materials and methods: The objective of this paper is to describe the causes and consequences of a misdiagnosis of drug allergy. We propose a method for establishing a correct diagnosis in the case of a history of a delayed reaction during treatment with a BLA. For this purpose, a proposal was discussed via e-mail communication, and consensus was reached among the members of the drug allergy working groups of the participating medical societies. Results: The suspicion of a BLA allergy based on the medical history alone can have a negative impact on future antibiotic treatment. Exanthema associated with febrile infections not related to drug administration is a frequent finding in children. This makes it all the more important to be able to recommend a standardized procedure for clarification in children and adolescents with suspected hypersensitivity reactions. The medical history should be the basis on which to diagnose either a drug allergy or another possible differential diagnosis. A mild maculopapular exanthema (MPE) can be an expression of a drug allergy or a nonspecific viral exanthema. Uncomplicated MPE is not associated with significant systemic involvement, and there is no involvement of the mucous membranes or cutaneous blistering. Only a small number of children with uncomplicated MPE show positive skin tests and only ~ 7 – 16% of suspected BLA diagnoses can be confirmed by provocation tests. Thus, in children with uncomplicated MPE, drug provocation can be performed in an outpatient setting even without prior skin testing. This paper presents a 3-day outpatient direct provocation scheme for BLA delabeling in children with uncomplicated MPE. Conclusion: Many children and adolescents are unnecessarily denied treatment with BLA after an uncomplicated MPE while being treated with a BLA.Correspondence to:

This guideline is a partial update of the S3 guideline on atopic dermatitis (AWMF register no. 013-027) published in 2023. The chapters on systemic therapy with biologics and Janus kinase inhibitors as well as the chapter on pregnancy, breastfeeding and family planning in the context of systemic therapies for atopic dermatitis have been updated. This was prompted by new approvals (lebrikizumab, nemolizumab), approval extensions (abrocitinib from 12 years of age, baricitinib from 2 years of age) and new evidence on the use of biologics before and during pregnancy. In addition, a new chapter on treatment goals, treatment expectations and criteria for treatment adjustment (“treat-to-target”) in systemic therapies has been added to the guideline. This article only presents the updated and newly added chapters. The complete guideline is available on the AWMF website.Correspondence to:
