Abstract
Hintergrund: Zur vorbeugenden Behandlung von COVID-19 (Coronaviruserkrankung 2019) wurden in einer beispiellosen weltweiten Forschungsanstrengung Sicherheit und Wirksamkeit neuer Impfstoffplattformen studiert, die noch nie zuvor am Menschen eingesetzt wurden. Weniger als ein Jahr nach der Entdeckung der SARS-CoV-2-Virussequenz (SARS-CoV-2, "severe acute respiratory syndrome coronavirus type 2") wurden diese in zahlreichen Ländern für den Einsatz zugelassen und es wurde mit Massenimpfungen begonnen. Die bislang in der Europäischen Union (EU) zugelassenen mRNA-Impfstoffe (mRNA, "messenger"-RNA) gegen SARS-CoV-2 BNT162b2 und mRNA-1273 basieren auf einer ähnlichen lipidbasierten Nanopartikelträgertechnologie; die Lipidkomponenten unterscheiden sich jedoch. Schwere allergische Reaktionen und Anaphylaxien nach COVID-19-Impfungen sind sehr seltene unerwünschte Nebenwirkungen, die aber aufgrund potenziell letaler Ausgänge viel Aufmerksamkeit erhalten und ein hohes Maß an Verunsicherung ausgelöst haben. Methoden: Das aktuelle Wissen zu anaphylaktischen Reaktionen auf Impfstoffe und speziell zu den derzeit neuen mRNA-COVID-19-Impfstoffen wurde zusammengestellt mittels einer Literaturanalyse durch Recherchen in Medline, Pubmed sowie den nationalen und internationalen Studien- und Leitlinienregistern, der Cochrane Library und dem Internet unter besonderer Berücksichtigung offizieller Webseiten der World Health Oranization (WHO), der Centers for Disease Control and Prevention (CDC), der European Medicines Agency (EMA), des Robert-Koch-Instituts (RKI) und des Paul-Ehrlich-Instituts (PEI). Ergebnisse: Basierend auf der internationalen Literatur und bisheriger Erfahrungen zu schweren allergischen Reaktionen im Kontext der COVID-19-Impfungen werden von einem Expertengremium Empfehlungen für Prophylaxe, Diagnostik und Therapie dieser allergischen Reaktionen gegeben. Schlussfolgerung: Vor einer COVID-19-Impfung mit den derzeit zugelassenen Impfstoffen sind Allergietests für die allermeisten Allergiker nicht notwendig. Bei allergischer/anaphylaktischer Reaktion auf den verabreichten COVID-19-Impfstoff wird eine allergologische Abklärung empfohlen, wie auch für eine kleine potenzielle Risikopopulation vor der ersten Impfung. Die Evaluierung und Zulassung von Testverfahren sollten hierfür erfolgen.

Abstract
Eczematous drug eruptions are a heterogenous group of skin reactions that resemble eczema both clinically and histologically. We reviewed the literature and cataloged the systemically administered medications that cause these eruptions, along with their characteristic clinical presentations. We identified three primary pathophysiologic etiologies: (1) cutaneous immunomodulation, (2) skin dehydration, and (3) delayed hypersensitivity. Notably, eczematous eruptions caused by altered immunity in the skin may be increasing in incidence as some responsible drugs, in particular biologic therapies (such as tumor necrosis factor-α and interleukin-17 inhibitors) and targeted cancer treatments (including immune checkpoint inhibitors and epidermal growth factor receptor inhibitors), become more commonly employed in clinical practice. Other notable causes of eczematous eruptions include antiviral agents for hepatitis C virus and cardiovascular medications in elderly individuals, and notable subtypes of eczematous reactions include systemic contact dermatitis and photoallergic reactions, which are also discussed. The diagnostic gold standard is drug rechallenge and most reactions may be treated effectively with emollients, topical corticosteroids, and oral antihistamines.

Abstract
BACKGROUND For the preventive treatment of the 2019 coronavirus disease (COVID-19) an unprecedented global research effort studied the safety and efficacy of new vaccine platforms that have not been previously used in humans. Less than one year after the discovery of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral sequence, these vaccines were approved for use in the European Union (EU) as well as in numerous other countries and mass vaccination efforts began. The so far in the EU approved mRNA vaccines BNT162b2 and mRNA-1273 are based on similar lipid-based nanoparticle carrier technologies; however, the lipid components differ. Severe allergic reactions and anaphylaxis after COVID-19 vaccination are very rare adverse events but have drawn attention due to potentially lethal outcomes and have triggered a high degree of uncertainty. METHODS Current knowledge on anaphylactic reactions to vaccines and specifically the new mRNA COVID-19 vaccines was compiled using a literature search in Medline, PubMed, as well as the national and international study and guideline registries, the Cochrane Library, and the Internet, with special reference to official websites of the World Health Organization (WHO), US Centers for Disease Control and Prevention (CDC), Robert Koch Institute (RKI), and Paul Ehrlich Institute (PEI). RESULTS Based on the international literature and previous experience, recommendations for prophylaxis, diagnosis and therapy of these allergic reactions are given by a panel of experts. CONCLUSION Allergy testing is not necessary for the vast majority of allergic patients prior to COVID-19 vaccination with currently licensed vaccines. In case of allergic/anaphylactic reactions after vaccination, allergy workup is recommended, as it is for a small potential risk population prior to the first vaccination. Evaluation and approval of diagnostic tests should be done for this purpose.

Abstract
Coronavirus disease 2019 (COVID-19), a respiratory tract infection caused by a novel human coronavirus, the severe acute respiratory syndrome coronavirus 2, leads to a wide spectrum of clinical manifestations ranging from asymptomatic cases to patients with mild and severe symptoms, with or without pneumonia. Given the huge influence caused by the overwhelming COVID-19 pandemic affecting over three million people worldwide, a wide spectrum of drugs is considered for the treatment in the concept of repurposing and off-label use. There is no knowledge about the diagnosis and clinical management of the drug hypersensitivity reactions that can potentially occur during the disease. This review brings together all the published information about the diagnosis and management of drug hypersensitivity reactions due to current and candidate off-label drugs and highlights relevant recommendations. Furthermore, it gathers all the dermatologic manifestations reported during the disease for guiding the clinicians to establish a better differential diagnosis of drug hypersensitivity reactions in the course of the disease.

Abstract
Chronic granulomatous disease (CGD) is a primary immunodeficiency that confers a markedly increased risk of bacterial and fungal infections caused by certain opportunistic pathogens. Current evidence supports the use of prophylactic antibacterial, antifungal, and immunomodulatory therapies designed to prevent serious or life-threatening infections in patients with CGD. In this review, we discuss current strategies for the prevention of infections in children and adults with CGD and the evidence that supports those strategies. In addition, we address current challenges and opportunities for future research in this important area.

Abstract
Polyethylene glycols (PEGs) or macrogols are polyether compounds widely used in medical and household products. Although generally considered biologically inert, cases of mild to life-threatening immediate-type PEG hypersensitivity are reported with increasing frequency. Nevertheless, awareness of PEG's allergenic potential remains low, due to a general lack of suspicion towards excipients and insufficient product labelling. Information on immediate-type reactions to PEG is limited to anecdotal reports, and the potential for PEG sensitization and cross-sensitization to PEGylated drugs and structurally related derivatives is likely underestimated. Most healthcare professionals have no knowledge of PEG and thus do not suspect PEG's as culprit agents in hypersensitivity reactions. In consequence, patients are at risk of misdiagnosis and commonly present with a history of repeated, severe reactions to a range of unrelated products in hospital and at home. Increased awareness of PEG prevalence, PEG hypersensitivity, and improved access to PEG allergy testing, should facilitate earlier diagnosis and reduce the risk of inadvertent re-exposure. This first comprehensive review provides practical information for allergists and other healthcare professionals by describing the clinical picture of 37 reported cases of PEG hypersensitivity since 1977, summarizing instances where PEG hypersensitivity should be considered and proposing an algorithm for diagnostic management.

Abstract
Cytokines, currently known to be more than 130 in number, are small MW (<30 kDa) key signaling proteins that modulate cellular activities in immunity, infection, inflammation, and malignancy. Key to understanding their function is recognition of their pleiotropism and often overlapping and functional redundancies. Classified here into 9 main families, most of the 23 approved cytokine preparations (19 different cytokines and 4 pegylated), all in recombinant human (rh) form, are grouped in the hematopoietic growth factor, interferon (IFN), platelet-derived growth factor (PDGF), and transforming growth factor β (TGFβ) families. In the hematopoietin family, approved cytokines are aldesleukin (rhIL-2), oprelvekin (rhIL-11), filgrastim and tbo-filgrastim (rhG-CSF), sargramostim (rhGM-CSF), metreleptin (rh-leptin), ancestim (rh-SCF), and the rh-erythropoietins, epoetin and darbepoetin alfa. Anakinra, a recombinant receptor antagonist for IL-1, is in the IL-1 family; recombinant interferons alfa-1, alfa-2, beta-1, and gamma-1 make up the interferon family; palifermin (rhKGF) and becaplermin (rhPDGF) are in the PDGF family; and rhBMP-2 and rhBMP-7 represent the TGFβ family. The main physicochemical features, FDA-approved indications, modes of action and side effects of these approved cytokines are presented. Underlying each adverse events profile is their pleiotropism, potency and capacity to release other cytokines producing cytokine “cocktails.” Side effects, some serious, occur despite cytokines being endogenous proteins, and this therefore demands caution in attempts to introduce individual members into the clinic. This caution is reflected in the relatively small number of cytokines currently approved by regulatory agencies and by the fact that 15 of the FDA-approved preparations carry warnings, with 10 being black box warnings.

Abstract
Dermatoses have been better characterized as hypochromic vitiligo in subjects with dark skin or the acquired racquet nails associated with hyperparathyroidism. The innate immunity has a central role in the new classification of auto inflammatory diseases, neutrophilic dermatoses, neutrophilic urticaria or pseudo-neutrophilic urticaria. Comorbidities have been studied e.g. cardiovascular co morbidities for psoriasis, IBD associated with hidradenitis suppurativa or neurological disorders associated with pemphigoid. Bullous pemphigoid could be renamed as cutaneous pemphigoid, it can be induced by drugs especially gliptins. Genetic predispositions are analyzed in auto inflammatory diseases, psoriasis (HLA), drug eruptions (HLA or cytokines). Telaprevir often induces rashes, which can be severe but other treatments against hepatitis C as interferon can also induce debilitating rashes, some eligible for drug tolerance induction. European guidelines for the definition, classification, diagnosis of chronic spontaneous urticaria have been published. Severe cutaneous adverse drug reactions may be associated with severe systemic symptoms such as organ involvement in AGEP or the occurrence of a shock in DRESS. Allover Europe, there is now an epidemic of contact allergies to methylisothiazolinone (MIT), contained in cosmetics, wet wipes but also in paints. MIT should be tested at 2.000 ppm in water, included in the standard series for patch tests. Its role has to be evoked in any case localized on the face or hand, airborne or generalized eczema. Among infectious diseases, skin manifestations due to Parvovirus have been specified, a febrile rash can be related to dengue infection or to Zika virus.

Abstract
Drug skin tests can reproduce delayed hypersensitivity to drugs and entail a moderate reexposure of patients to offending drugs. Drug patch tests (DPTs) and prick tests can be done with any commercialized form of a drug. In non-severe delayed non-IgE-mediated reactions to drugs, intradermal tests (IDT) with delayed readings have a greater value, but their techniques lack standardization. A negative drug skin test does not exclude the responsibility of a drug, and the drug must be rechallenged in non-severe cases. DPTs are useful in maculopapular rashes, flexural exanthemas, and if done in situ, also in fixed drug eruption. Their best indication is in acute generalized exanthematous pustulosis or drug reaction with eosinophilia and systemic symptoms (DRESS). They should be carried out cautiously, following strict guidelines. Prick tests have a low value but they can sometimes be positive on delayed readings. In non-severe delayed reactions to drugs, intradermal tests with delayed readings are the most sensitive skin tests especially for beta-lactam antibiotics, radiocontrast media, heparins but also some biological agents. The value of patch testing varies according to the implicated drug and the non-immediate adverse drug reaction. In DRESS, DPTs have a good value in testing carbamazepine or proton pump inhibitors but remain negative in testing with allopurinol or salazopyrin. In toxic epidermal necrolysis, DPTs are safe but positive in only 9 to 23 % of the reported cases.
