RESUMEN
PURPOSE: Atopic dermatitis (AD) is a chronic skin disease affecting 10% of children in Europe. The treatment of AD is well codified; however, a gap sometimes exists between recommendations and medical practice. The objective of this study was to assess the practice of French pediatricians regarding the management of AD. METHODS: We conducted a national practice survey from September 2021 to October 2021, using an online questionnaire emailed to pediatric physicians. RESULTS: A total of 83 pediatricians from 33 different departments responded to the survey. The clinical features of AD were known by the majority of pediatricians, but 15 (18%) found the diagnosis difficult to establish. All pediatricians prescribed daily applications of emollients and 78 (94%) prescribed topical corticosteroids (TCS) during AD flares, but misuses remained: only 29 (35%) pediatricians prescribed TCS when eczema (even if minimal) appeared and 43 (52%) did so at the onset of pruritus, while 45 (54%) prescribed them for extensive or disabling eczema, and 53 (64%) when eczema persisted after an initial treatment with emollients. Regarding diet, 12 (14%) pediatricians recommended a diet low on or free of cow milk, 10 (12%) systematically referred children with AD to an allergist, and 20 (24%) delayed food diversification. CONCLUSION: Despite improvements in AD management by French pediatricians in the past 15 years, barriers to its appropriate management still persist, including the misuse of TCS and inappropriate diets.

Introduction: The health context with COVID-19 pandemic has led to fast development of many vaccines against the SarS-Cov-2 virus. Four of them are currently available in France and contain polyethylene glycol (PEG) or polysorbate 80 as excipients, already described as causing anaphylaxis. French recommendations have been suggested by allergology authorities and proposed a course of action in the event of a suspected allergy to these vaccines. Thus, allergies to excipients were the only contraindication to COVID-19 vaccination. Our main objective was to determine the impact of these allergology vaccine recommendations on the management of these patients. Our secondary objective was to determine prevalence of true allergies to these vaccines. Materials and methods: We conducted a unicentric descriptive retrospective study with all patients over 18 years of age referred for an allergological opinion before or after an injection of one of the anti-COVID-19 vaccines. Nineteen patients were classified into different interest groups, based on french recommendations. Results: The vast majority of patients did not require a pre-vaccination allergological assessment. Indeed, only 25 patients received skin tests prior to vaccination. The rest of patients were able to be vaccinated without allergological assessment. Patients not vaccinated due to allergy to excipients represent less than 1% of the population (n = 3/320). Conclusion: French recommendations made it possible to vaccinate the vast majority of patients included in our study. Allergy to PEG, polysorbate or their derivatives, the only contraindication to anti-COVID vaccination, according to the recommendations of February 2021, remains rare. Today, several authors propose tolerance inductions allowing the vaccination of patients allergic to PEGs or their derivatives with good tolerance.
RESUMEN
BACKGROUND: Dupilumab is the first biotherapy available for the treatment of moderate-to-severe childhood atopic dermatitis (AD). OBJECTIVE: The aim of this study was to evaluate the effectiveness and safety of dupilumab in daily practice. METHODS: Patients aged 6-11, who had received a first dose of dupilumab, were included in this multicentre retrospective cohort study. The primary endpoint was change in SCORAD after 3 months of treatment. Secondary endpoints were change in IGA score at 3 months, proportion of patients with SCORAD50 and SCORAD75, description of adverse events and proportion of children in our cohort who would be excluded from pivotal phase 3 clinical trial. RESULTS: Eighty patients were included. After 3 months of treatment, there was a significant decrease in SCORAD (mean: 21.8 ± 13.8 vs 53.9 ± 18.5; P < 0.0001) and IGA (1.3 ± 0.8 vs 3.5 ± 0.7; P < 0.0001). Conjunctivitis was observed in 11.3% (n = 9/80); three patients experienced dupilumab facial redness (DFR); 17.5% (n = 14/80) reported injection site reactions; 6.3% (n = 5/80) discontinued treatment. 61.2% (n = 49/80) children were ineligible in the phase 3 trial. LIMITATIONS: There is no control group. Because it was a real life study based on information from patient medical records in a French multicentre cohort, we cannot rule out the presence of reporting bias generated by the use of patient reported characteristics and missing information. CONCLUSION: These real-life data confirm the efficacy and safety of dupilumab in children with moderate to severe AD extended to dyshidrosis and atopic prurigo, but it also revealed a lower frequency of DFR and conjunctivitis. However, administration in injectable form may be a barrier in this age group.

BACKGROUND: Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by unrelenting pruritus and recurrent eczematous lesions. It affects up to 15% of children and adolescents and up to 5% of adults, and confers a high and multifactorial burden to patients, families and society. With increasing awareness of this substantial burden, AD has become a priority for healthcare systems. AIM: The Atopic Dermatitis Quality of Care (ADQoC) initiative set out to describe good practices for addressing the challenges that impede the management of AD. METHODS: The initiative carried out a literature review and surveyed 32 expert care centres, catalogued findings, and analysed and elucidated global challenges to AD care along with good practice implementations that can address them. RESULTS: The four challenges to quality care for AD are: (i) misconceptions about AD; (ii) delayed referral and access to AD specialists; (iii) poor patient access to AD treatments and poor adherence to medications; and (iv) managing the complexity of AD and its comorbidities. The initiative highlighted 5 of 10 good practice implementations as high priority for any AD care centre to focus on: (i) clinical assessment and diagnosis; (ii) a structured multidisciplinary care team; (iii) monitoring and evaluating care quality; (iv) patient education and communication; and (v) collaboration and exchange with patient groups. CONCLUSION: These implementations can provide benefits for patients, healthcare providers and the healthcare system. They directly contribute to the efficacy of treatment, improved healthcare provider efficiency, improved education for patients and healthcare providers, and improved costs to healthcare systems. The initiative was launched on https://atopicdermatitiscare.kpmg.co.uk/ to provide an easy-to-use educational platform.

Atopy is defined by the propensity to develop an exaggerated type-2 inflammatory response to environmental molecules. Clinically, atopy is diagnosed when atopic disease occurs: atopic dermatitis, food allergy, atopic asthma and allergic rhinitis and conjunctivitis. Whereas the classical "atopic march" is increasingly challenged through epidemiological studies, type-2 cellular inflammation is a characteristic shared by the atopic diseases. This inflammation can be innate (non-specific: eosinophils, mast cells, dendritic cells, innate lymphoid cells [ILC]), or adaptive (antigen-specific, involving T cells). Interleukins (IL-)4, 5 and 13 are major actors of type-2 inflammation and are mainly produced by ILC and T cells. The efficacy of treatments targeting these type-2 cytokines highlight the importance of type-2 inflammation in atopic diseases. However, several patients do not respond to type-2 targeting treatments, highlighting the presence of other actors in pathophysiology of atopic diseases: alteration of epithelial barrier, IgE-mediated allergic responses, type-17 inflammation. Thus, the term "endotype" can illustrate this diversity in pathophysiology. Finally, a global approach of atopic diseases, as type-2 inflammatory diseases, is fundamental, but not sufficient. An approach by endotype is advisable, in a personalized medicine perspective. © 2020 Elsevier Masson SAS. All rights reserved.

BACKGROUND: The therapeutic options in atopic dermatitis rely on consensus-based guidelines, also established for psoriasis and chronic urticaria. However, the therapeutic approach in atopic dermatitis, especially in the moderate-to-severe forms of the disease, seems less aggressive than in psoriasis and in chronic urticaria with a less frequent use of systemic agents. OBJECTIVES: To compare in real-life conditions the therapeutic management of adults with atopic dermatitis with those with psoriasis and chronic urticaria. METHODS: A transversal analysis was performed in May 2017, using retrospective data from a monocentric database. Data on epidemiology, severity, therapeutic educational intervention and systemic treatments were analysed from 401 patients with atopic dermatitis, compared with data from 230 patients with chronic urticaria and 535 patients with psoriasis. RESULTS: A high proportion (73%) of atopic dermatitis patients presented with a moderate-to-severe form of the disease compared to only 39% of chronic urticaria and 17% of psoriasis patients. Most of atopic dermatitis patients (78%) had completed a therapeutic educational programme, while the adherence was lower in chronic urticaria (35%) and in psoriasis (3%) patients. A systemic treatment, including biologicals, was recorded in 8% of atopic dermatitis patients, while it concerned 26% and 47% of chronic urticaria and psoriasis patients, respectively. CONCLUSIONS: We confirmed that atopic dermatitis treatment mostly relies on topical treatments. Only a minority of moderate-to-severe atopic dermatitis patients who are eligible for a systemic treatment receive such therapy. This may suggest promoting a more frequent use of systemic agents in moderate-to-severe atopic dermatitis.

BACKGROUND: One of the major reasons to stop antibiotic prophylaxis (AP) to prevent infective endocarditis (IE) in the United Kingdom but not in the rest of the world was that it would result in more deaths from fatal adverse drug reactions (ADRs) than the number of IE deaths. The main aim of this study was to quantify and describe the ADRs with amoxicillin or clindamycin for IE AP. The second aim was to infer a crude incidence of anaphylaxis associated with amoxicillin for IE AP. STUDY DESIGN: The Medical Dictionary for Regulatory Activities (MedDRA) was used to group ADRs for IE AP using the broad Standardized MedDRA Queries "Anaphylactic reaction, Amoxicillin, Clindamycin, Clostridium Difficile infection" to the French Pharmacovigilance Database System. From this first-line collection, we selected all cases occurring for IE AP and ultimately, the cases for IE AP for a dental procedure. Then, each case was analyzed. RESULTS: Of 11639 first-line recorded ADRs, 100 were for IE AP but no fatal anaphylaxis to amoxicillin or clindamycin and no C. difficile infection associated with clindamycin were identified. Only 17 cases of anaphylaxis to amoxicillin related to dental procedures were highlighted. The estimation of the crude incidence rate of anaphylaxis associated with amoxicillin for IE AP for invasive dental procedure was 1/57 000 (95% CI 0.2-0.6). CONCLUSIONS: Fatal or severe ADRs with amoxicillin or clindamycin is not a rational argument to stop IE AP before invasive dental procedures.

Non-steroidal anti-inflammatory drugs (NSAIDs) are the most common providers of immediate hypersensitivity reactions. Among these reactions, isolated acute urticaria is the most common clinical feature with a non-allergic origin. It is a pharmacological side effect resulting from the alteration of arachidonic acid metabolism induced by NSAIDs. Diagnosis of this acute urticaria is clinical, requiring no allergy testing. Currently, the recommended therapeutic management of NSAID urticaria is the avoidance of all NSAID with COX-1 inhibitor activity (even if when reintroduced, they are most often well tolerated) and the use of selective COX-2 inhibitors. This review focuses on urticaria reactions to NSAIDs, which are simple to manage.

Atopic dermatitis (AD) is a common frequent chronic inflammatory skin disease which begins frequently in infancy. The clinical expression of AD is a recurrent eczema on a dry skin. AD is a multifactorial disease characterized by two linked abnormalities: a skin barrier defect and a cellular inflammation, with type-2 main components. However, the pathophysiology of AD is not as simple as this description looks like. In this review, we will present a synthesis of current knowledge on natural history of AD and the involved factors, in order to clarify AD care. The evolution of AD is associated with many atopic comorbidities, following the "atopic march" scheme: IgE-mediated food allergy, allergic asthma and rhinitis occurring classically after AD. In fact, this is rarely the case, but the atopic march seems to be associated with AD severity. AD has also many neuropsychological complications which are essential to be detected. Other factors could influence the natural history of AD: genetic mutations on different genes (proteins of skin barrier, innate and adaptive immunity pathways), skin dysbiosis with colonization by Staphylococcus aureus, sensitization against environmental proteins. AD treatment is based on the restauration of the skin barrier using emollients and on anti-inflammatory drugs (notably topical corticosteroids) during the inflammatory flares. It is not recommended to treat the skin colonization by S. aureus, excepted in case of skin infection. The probiotics have no efficiency as curative treatment of AD, but could have an interest for the primary prevention, especially in at-risk populations. © 2019 Elsevier Masson SAS.
