Atopic dermatitis (AD) normally onsets in childhood and mostly resolves before adolescences. Disease persistence is known to be difficult to study properly, and current predictors are insufficient to identify more than a small fraction of patients at risk.
特应性皮炎(AD)通常在儿童期发病,多数在青春期前消退。众所周知,疾病的持续性很难进行适当的研究,目前的预测指标不足以确定一小部分有风险的患者。

Since the Osler's identification of the inherited nature of hereditary angioedema, a huge array of information was collected on pathogenetic mechanisms of the disease. Over the last years, information grew fast, and mutations in different genes, in addition to C1‐inhibitor, were found to be causative. All types are inherited as autosomal‐dominant traits with incomplete penetrance and little or no genotype‐phenotype correlation. As a result, the clinical expression is characterized by a large heterogeneity. The acknowledgement of mechanisms leading to heterogeneity of the clinical phenotype is likely to provide important information not only for a better understanding of the pathogenesis but also for therapy. Regardless of which gene is mutated, similar pathways seem to play a pivotal role, triggering the up‐regulation of contact activation system/kallikrein kinin system and giving rise to an unbalanced increase of bradykinin. However, notwithstanding the increase of bradykinin in bloodstream, the phenomenon is localized and no general vascular leakage and oedema is recognized. Thus, it is conceivable that there exist one or more localized factors that stimulate the production of bradykinin, which does not become a systemically event. Uncovering of these factors may shed lights on the missing part of the pathogenesis of hereditary angioedema. The present review, collecting information on pathogenesis from biochemical and genetics investigations, tries to provide a comprehensive view of the pathogenesis of hereditary angioedema. This can allow for a better understanding of the disease and lead to focused investigations that can further improve our knowledge.
自奥斯勒发现遗传性血管性水肿的遗传特性以来,人们收集了大量关于该病发病机制的信息。在过去的几年里,信息增长迅速,除了C1抑制剂外,不同基因的突变也被发现是致病的。所有类型遗传为常染色体显性性状,具有不完全外显率和很少或没有基因型-表型相关性。因此,临床表现具有较大的异质性。承认导致临床表型异质性的机制可能不仅为更好地理解发病机制而且为治疗提供重要信息。无论哪个基因突变,相似的途径似乎起着关键作用,触发接触激活系统/缓激肽激肽系统的上调,并引起缓激肽的不平衡增加。然而,尽管血液中的缓激肽增加,但这种现象是局部的,没有普遍的血管渗漏和水肿。因此,可以想象,存在一个或多个局部因素刺激缓激肽的产生,而不是成为系统性事件。这些因素的发现可能会揭示遗传性血管性水肿发病机制的缺失部分。本文从生物化学和遗传学两方面综述了遗传性血管性水肿的发病机制,以期对其发病机制有一个全面的认识。这可以让我们更好地了解这种疾病,并导致有针对性的调查,从而进一步提高我们的知识。

Understanding consumer perceptions is crucial if effective food safety policy and risk communication are to be developed and implemented. We sought to understand how those living with food allergy assess risk with precautionary allergen labelling (PAL) and their preference in how risks are communicated within a quantitative risk assessment (QRA) framework.

Research over the past 20 years has demonstrated the significant impact food allergy can have on quality of life and mental health of patients and their families, yet there is a paucity of psychological services to support families in coping with this condition. This paper provides a short overview of the psychological impact of food allergy, followed by a discussion of the use of paediatric psychological services for long‐term conditions. To our knowledge, few paediatric allergy clinics in the UK have funding for dedicated clinical psychology services. Two such services are based at Southampton General Hospital and the Evelina London Children's Hospital. This paper includes descriptions of these services and how they are currently being used by patients and families. This is followed by an allergy clinician's perspective on the use of psychological services. Recommendations are made for allergy services to work with hospital psychology services to develop, integrate and deliver psychological services for all patients with allergy and their families who are in need. Future research also needs to focus on the efficacy of psychological therapies and group interventions in food allergy.
研究在过去的20年里已经展示了重大影响食物过敏对生活质量和心理健康的患者和他们的家庭,然而,有一个缺乏心理服务,以支持家庭应付这种情况。本文简要介绍了食物过敏的心理影响,然后讨论了长期使用儿科心理服务的情况。据我们所知,英国很少有儿科过敏诊所有专门的临床心理学服务资金。南安普敦总医院和伊芙琳娜伦敦儿童医院有两家这样的医院。本文包括这些服务的描述,以及它们目前是如何被患者和家属使用的。这是紧随其后的是一个过敏的临床医生的角度对心理服务的使用。建议过敏服务部门与医院心理服务部门合作,为所有有需要的过敏患者及其家属开发、整合和提供心理服务。未来的研究还需要关注心理疗法和群体干预对食物过敏的疗效。

The uncertainties and anxieties around food allergy 食物过敏的不确定性和焦虑
Pub Date : 2019-11-01 DOI: 10.1111/cea.13520

A report in the European Respiratory Journal now provides an ex‐ planation for how obesity and asthma may be linked.1 Margaglione et al examined the airway wall for adipose tissue in individuals with and without asthma. Adipose tissue was found only in the outer wall of large airways. They found that the amount of adipose tissue was associated with body mass index, wall thickness and the number of inflammatory cells. These latter two phenomena could readily give rise to an adiposity‐related asthma presentation (Figure 1). In this issue of the journal, Knibb et al argue that there is a need for better access to psychological services to support families to cope with food allergy.2 Food allergy has a pervasive impact on patients and their families. With the issues around precautionary labelling,3,4 those affected experience continued uncertainty and therefore anxiety about whether what they about to eating food that is contaminated with their triggering allergen. This can seriously impact on their activities and quality of life. The authors describe psychological approaches that may be helpful to patients who are particularly affected.5 Working in an allergy service multidisciplinary team that includes a psychologist, I can provide first‐hand support for their argument. Continuing on the theme of precautionary labelling, I should mention one of my papers.6 Within the iFAAM project, we surveyed consumers across Europe with food allergy. We aimed to under‐ stand how they assess risk with precautionary allergen labelling and this could be improved. Our focus was on the use of a Quantitative Risk Assessment framework. Within this evidence‐based approach would mean that only products likely to cause a reaction would have a precautionary allergen label.7 This would deliver certainty for con‐ sumers with allergies and help healthcare professionals give better advice.4,8 Finally, Smeekens et al have looked at whether indoor dust pro‐ motes airway sensitization to peanut and peanut allergy develop‐ ment in mice, as they do for aeroallergens.9 In this model, inhalation of low levels of peanut only caused peanut allergy when combined with indoor dust (Figure 1). So environmental adjuvants in indoor dust may be important determinants of the development of peanut allergy in childhood.
《欧洲呼吸杂志》上的一篇报道为肥胖和哮喘之间的联系提供了解释Margaglione等人检查了哮喘患者和非哮喘患者气道壁的脂肪组织。脂肪组织仅存在于大气道的外壁。他们发现脂肪组织的数量与身体质量指数、壁厚和炎症细胞的数量有关。后两种现象很容易导致肥胖相关的哮喘症状(图1)。在本期杂志中,Knibb等人认为,有必要提供更好的心理服务,以支持家庭应对食物过敏食物过敏对病人和他们的家庭有着广泛的影响。由于有关预防性标签的问题,3,4受影响的人经历了持续的不确定性,因此对他们所吃的食物是否被引发过敏原污染感到焦虑。这会严重影响他们的活动和生活质量。作者描述了可能对特别受影响的患者有帮助的心理学方法在包括心理学家在内的过敏服务多学科团队中工作,我可以为他们的论点提供第一手支持。继续关于预防性标签的主题,我要提一下我的一份文件在iFAAM项目中,我们调查了欧洲各地食物过敏的消费者。我们的目的是了解他们如何用预防性过敏原标签评估风险,这是可以改进的。我们的重点是使用定量风险评估框架。在这种基于证据的方法中,意味着只有可能引起反应的产品才会有预防性过敏原标签这将为过敏的消费者提供确定性,并帮助医疗保健专业人员提供更好的建议。最后,Smeekens等人研究了室内粉尘是否会促进小鼠对花生的气道致敏和花生过敏的发展,就像它们对空气过敏原所做的那样在这个模型中,吸入低水平的花生仅在与室内灰尘结合时才会引起花生过敏(图1)。因此,室内灰尘中的环境佐剂可能是儿童时期花生过敏发展的重要决定因素。

Glucocorticoids (GC) are considered first‐line therapy for most patients with hypereosinophilic syndrome (HES). Although response rates are generally high, many patients require moderate to high doses for control of eosinophilia and symptoms, and up to 15% of patients do not respond at all. Despite this, little is known about the mechanisms of GC resistance in patients with HES.
糖皮质激素(GC)被认为是大多数高嗜酸性粒细胞综合征(HES)患者的一线治疗方法。虽然反应率普遍较高,但许多患者需要中至高剂量来控制嗜酸性粒细胞增多和症状,高达15%的患者根本没有反应。尽管如此,对HES患者的GC耐药机制知之甚少。

The skin microbiome, characterized by an overgrowth of Staphylococcus aureus, plays an important role in the pathogenesis of atopic dermatitis (AD). Multidisciplinary treatment in alpine climate is known for its positive effect on disease severity in children with AD and can result in a different immune response compared with moderate maritime climate. However, the effect on the composition of the skin microbiome in AD is unknown.

Food allergy affects a small but significant number of children and adults. Food allergy is responsible for considerable morbidity and is the commonest cause of anaphylaxis in children. One of the aims of the European Union‐funded “Integrated Approaches to Food Allergen and Allergy Risk Management” (iFAAM) project was to improve our understanding of the best way to prevent the development of food allergy. Groups within the project worked on integrating the current prevention evidence base as well as generating new data to move our understanding forward. This paper from the iFAAM project is a unique addition to the literature on this topic as it not only outlines the recently published randomized controlled trials (as have previous reviews) but also summarizes two iFAAM‐associated project workshops. These workshops focused on how we may be able to use dietary strategies in early life to prevent the development of food allergy and summarized the range of opinions amongst experts in this controversial area.
食物过敏对儿童和成人的影响虽小,但数量可观。食物过敏是造成相当高发病率的原因,是儿童过敏反应的最常见原因。欧盟资助的“食物过敏原和过敏风险管理综合方法”(iFAAM)项目的目标之一是提高我们对预防食物过敏发展的最佳方法的理解。该项目的小组致力于整合当前的预防证据基础,并生成新的数据,以推动我们的理解。来自iFAAM项目的这篇论文是对这一主题的文献的独特补充,因为它不仅概述了最近发表的随机对照试验(如先前的综述),而且总结了两个iFAAM相关的项目研讨会。这些研讨会的重点是我们如何能够在生命早期使用饮食策略来预防食物过敏的发展,并总结了专家们在这个有争议的领域的观点。

Upskilling healthcare professionals to manage clinical allergy 提高医疗保健专业人员管理临床过敏的技能
Pub Date : 2019-10-06 DOI: 10.1111/cea.13497

It has long been recognised that given the high prevalence and considerable impact of allergic disease globally, there needs to be a focus on appropriate training for clinical professionals. The health‐economic consequences of allergic disease are significant, with both direct healthcare costs (doctor, nurse and dietitian consultations, hospital admissions and prescribed medications) and indirect costs (lost school and work time, reduced productivity and over‐the‐counter medications). There is also a well‐recognised impairment of quality of life, with less tangible costs including anxiety, distress, discomfort, disability and, occasionally, death. To help to mitigate these effects, there is a need to upskill the professional workforce at all levels, and also to equip those trained with the skills to become future healthare professional trainers. Upskilling the workforce from the grass‐roots of undergraduate study in Medical, Nursing and Allied Health Professionals (AHP) through the entirety of training to senior consultant levels could have a major beneficial impact on the patient and their families, lead to a reduction in emergency use of clinical service, and help increase economic productivity.
人们早就认识到,鉴于过敏性疾病在全球范围内的高患病率和相当大的影响,需要重点关注对临床专业人员的适当培训。过敏性疾病的健康经济后果是显著的,既有直接医疗成本(医生、护士和营养师咨询、住院和处方药物),也有间接成本(上学和工作时间减少、生产力降低和非处方药物)。还有一种公认的生活质量损害,其有形成本较低,包括焦虑、痛苦、不适、残疾,偶尔还有死亡。为了帮助减轻这些影响,需要提高各级专业人员的技能,并使受过培训的人具备成为未来保健专业培训人员的技能。从医学、护理和联合卫生专业人员(AHP)的基层本科学习到高级顾问水平的全面培训,提高劳动力的技能,可能对患者及其家属产生重大有益影响,减少临床服务的紧急使用,并有助于提高经济生产力。
