Abstract
The 2019 Interactive Derma Academy (IDeA) meeting was held in Lisbon, Portugal, 10-12 May, bringing together leading dermatology experts from across Europe, the Middle East and Asia. Over three days, the latest developments and challenges in relation to the pathophysiology, diagnosis, evaluation and management of dermatological conditions were presented, with a particular focus on acne, atopic dermatitis (AD) and actinic keratosis (AK). Interesting clinical case studies relating to these key topics were discussed with attendees to establish current evidence-based best practices. Presentations reviewed current treatments, potential therapeutic approaches and key considerations in the management of acne, AK and AD, and discussed the importance of the microbiome in these conditions, as well as the provision of patient education/support. It was highlighted that active treatment is not always required for AK, depending on patient preferences and clinical circumstances. In addition to presentations, two interactive workshops on the diagnosis and treatment of sexually transmitted infections/diseases (STIs/STDs) presenting to the dermatology clinic, and current and future dermocosmetics were conducted. The potential for misdiagnosis of STIs/STDs was discussed, with dermoscopy and/or reflectance confocal microscopy suggested as useful diagnostic techniques. In addition, botulinum toxin was introduced as a potential dermocosmetic, and the possibility of microbiome alteration in the treatment of dermatological conditions emphasized. Furthermore, several challenges in dermatology, including the use of lasers, the complexity of atopic dermatitis, wound care, use of biosimilars and application of non-invasive techniques in skin cancer diagnosis were reviewed. In this supplement, we provide an overview of the presentations and discussions from the fourth successful IDeA meeting, summarizing the key insights shared by dermatologists from across the globe.

Abstract
Social and psychosocial factors are thought to have an effect on the course of atopic eczema. The aim of this scoping review was to search for and summarize observational studies that investigated the effects of (psycho-)social factors on symptoms in atopic eczema and to identify research gaps. We searched PubMed and PsycINFO for literature published between 1 January 1989 and 31 December 2019 using a systematic search strategy. We included observational studies that analysed the effect of (psycho-)social factors on symptom severity in atopic eczema patients. Reviews and non-observational studies, articles with research on animals, and articles with languages other than English or German were excluded. We identified 17 observational studies that met the inclusion criteria. Several studies found significant results for an exacerbating effect of stress on atopic eczema severity. Although coping and social support does not seem to moderate the effect of stress, coping strategies might mediate the impact that stress has on symptoms. Depression is associated with atopic eczema severity. The effect of depression as a consequence of atopic eczema severity is stronger than the effect as an exacerbating factor. Illness identity, anger, frustration and psychosomatic states have been found to affect atopic eczema symptoms. For attachment security, anxiety and social status, contradictory results were found. Statistically non-significant results were reported for personality, being in a partnership, satisfaction with the partnership, childhood experiences and body consciousness. Only the association between psychosocial stress and atopic eczema symptom severity seems robust. To date, other (psycho-)social factors, especially protective and health-promoting factors, were analysed only in a few studies, mostly with low sample sizes and cross-sectional design. Biopsychosocial interactions between stress, protective factors and the course of atopic eczema as well as the psycho-neuroimmunological mechanisms underlying those interactions are considered fields for future research contributions.

Abstract
Patients with atopic dermatitis (AD) have an increased risk of bacterial skin infections, which cause significant morbidity and, if untreated, may become systemic. Staphylococcus aureus colonizes the skin of most patients with AD and is the most common organism to cause infections. Overt bacterial infection is easily recognized by the appearance of weeping lesions, honey‐coloured crusts and pustules. However, the wide variability in clinical presentation of bacterial infection in AD and the inherent features of AD – cutaneous erythema and warmth, oozing associated with oedema, and regional lymphadenopathy – overlap with those of infection, making clinical diagnosis challenging. Furthermore, some features may be masked because of anatomical site‐ and skin‐type‐specific features, and the high frequency of S. aureus colonization in AD makes positive skin swab culture of suspected infection unreliable as a diagnostic tool. The host mechanisms and microbial virulence factors that underlie S. aureus colonization and infection in AD are incompletely understood. The aim of this article is to present the latest evidence from animal and human studies, including recent microbiome research, to define the clinical features of bacterial infections in AD, and to summarize our current understanding of the host and bacterial factors that influence microbial colonization and virulence.

Abstract
Betula pollen is frequently found in the atmosphere of central and northern Europe. Betula pollen are health relevant as they cause severe allergic reactions in the population. We developed models of thermal requirements to predict start, peak and end dates of the Betula main pollen season for Bavaria (Germany). Betula pollen data of one season from 19 locations were used to train the models. Estimated dates were compared with observed dates, and the errors were spatially represented. External validation was carried out with time series datasets of 3 different locations (36years in total). RESULTS: The temperature requirements to detonate the main pollen season proved non-linear. For the start date model (error of 8,75days during external validation), daily mean temperatures above a threshold of 10°C from 28th of February onwards were the most relevant. The peak model (error of 3.58days) takes into account mean daily temperatures accumulated since the first date of the main pollen season in which the daily average temperature exceeded 11°C. The end model (error of 3.75days) takes into account all temperatures accumulated since the start of the main pollen season. CONCLUSION: These models perform predictions that enable the allergic population to better manage their disease. With the established relationship between temperatures and pollen season dates, changes in the phenological behaviour of Betula species due to climate change can be also estimated in future studies by taking into account the different climate scenarios proposed by previous climate change studies.

Abstract
Background Conjunctivitis is common in patients with atopic dermatitis (AD) in general and a commonly reported adverse event in AD clinical trials with dupilumab. Objective To survey opinions and experience about conjunctivitis occurring in AD, including those during dupilumab treatment in a group of AD experts from the International Eczema Council (IEC). Methods Electronic survey and in‐person discussion of management strategies. Results Forty‐six (53.5%) IEC members from 19 countries responded to the survey. Consensus was reached for several statements regarding diagnostic workup, referral and treatment. IEC members suggest that patients with AD should (i) routinely be asked about ocular complaints or symptoms, (ii) obtain information about the potential for conjunctivitis before starting dupilumab therapy and (iii) if indicated, be treated with dupilumab despite previous or current conjunctivitis. In cases of new‐onset conjunctivitis, there was consensus that dupilumab treatment should be continued when possible, with appropriate referral to an ophthalmologist. Limitations The study relies on expert opinion from dermatologists. Responses from few dermatologists without dupilumab access were not excluded from the survey. Conclusion The IEC recommends that dermatologists address conjunctivitis in patients with AD, especially during treatment with dupilumab.

Abstract
BACKGROUND Incidence of anal carcinoma is increased in people living with HIV (PLWH). Due to the improved life expectancy in PLWH, identifying appropriate prevention strategies for non-AIDS-defining cancer types such as anal carcinoma has become a priority in managing PLWH today. OBJECTIVE We aimed to evaluate anal cytology assessment as screening tool for anal dysplasia and/or carcinoma in PLWH, regardless of gender or sexual orientation. Additionally, we investigated the correlation between cancer risk factors and abnormal screening results in our patient cohort. METHODS People living with HIV from the Interdisciplinary HIV Centre of the University Hospital rechts der Isar in Munich, Germany (IZAR), were screened for anal carcinoma by single cytobrush examination and anal Papanicolaou (PAP) smear assessment from 2013 to 2015. Patients with abnormal PAP smear result were offered a follow-up examination after 12 months. Differences between two groups were tested for statistical significance using Student's t-test and Mann-Whitney U-test, as appropriate. RESULTS In total, 101 PLWH were included. 26.7% of subjects (n = 27) were PAP IIID, and 9.9% (n = 10) were PAP IVa. Seven female subjects had an abnormal finding at screening. Smoking was significantly associated with abnormal findings at screening (P = 0.005). In addition, our study found an association between sexually transmitted infections (STI) and anal dysplasia. Condylomata acuminata were increased in subjects with PAP IIID/PAP IVa (P = 0.045). Reactive syphilis serology was found to be significantly associated with abnormal screening results (P = 0.016), respectively. CONCLUSION Our results demonstrate that smoking and two common STIs, condylomata acuminata and syphilis, are risk factors associated with advanced anal intraepithelial neoplasia (AIN) stages in our PLWH cohort. While further analysis is needed to determine diagnostic guidelines concerning AIN in PLWH, these results suggest that interdisciplinary lifestyle prevention strategies are required to reduce the risk factors for AIN in PLWH in an outpatient setting.

Abstract
BACKGROUND Besides allergens, pollen release bioactive, low molecular weight compounds that modulate and stimulate allergic reactions. Clinical relevance of these substances has not been investigated to date. OBJECTIVE To elucidate the effect of a non-allergenic, low molecular weight factors from aqueous birch pollen extracts (Bet-APE < 3 kDa) on the human allergic immune response in vivo. METHODS Birch and grass pollen allergic individuals underwent skin prick testing with allergen alone, allergen plus Bet-APE < 3 kDa, or allergen plus pre-identified candidate substances from low molecular pollen fraction. Nasal allergen challenges were performed in non-atopic and pollen allergic individuals using a 3 day repeated threshold challenge battery. Subjects were either exposed to allergen alone or to allergen plus Bet-APE< 3 kDa. Local cytokine levels, nasal secretion weights, nasal congestion and symptom scores were determined. RESULTS Skin prick test reactions to pollen elicited larger weals when allergens were tested together with the low molecular weight compounds from pollen. Similar results were obtained with candidate pollen-associated lipid mediators. In nasal lining fluids of allergic patients challenged with allergen plus Bet-APE < 3 kDa, IL-8 and IgE was significantly increased as compared to allergen-only challenged patients. These patients also produced increased amounts of total nasal secretion and reported more severe rhinorrhea than the allergen-only challenged group. CONCLUSIONS Low molecular compounds from pollen enhance the allergen specific immune response in the skin and nose. They are therefore of potential clinical relevance in allergic patients.

Abstract
BACKGROUND B cells play a central role in IgE-mediated allergies. In damaged airway epithelium, they are exposed directly to aeroallergens. We aimed to assess whether direct exposure of B cells to pollen constituents affects allergic sensitization. METHODS B cells from murine splenocytes and from blood samples of healthy donors were incubated for 8 days under Th2-like conditions with aqueous ragweed pollen extracts (Amb-APE) or its constituents. Secreted total IgM, IgG, and IgE was quantified by ELISA. Additionally, birch, grass, or pine-pollen extracts were tested. The number of viable cells was evaluated by ATP measurements. B-cell proliferation was measured by CFSE staining. IgE class switch was analyzed by quantitation of class switch transcripts. In an OVA/Alum i.p.-sensitization mouse model, Amb-APE was intranasally instilled for 11 consecutive days. RESULTS Upon Th2 priming of murine B cells, ragweed pollen extract caused a dose-dependent increase in IgE production, while IgG and IgM were not affected. The low-molecular-weight fraction and phytoprostane E1 (PPE1) increased IgE production, while Amb a 1 did not. PPE1 enhanced IgE also in human memory B cells. Under Th1 conditions, Amb-APE did not influence immunoglobulin secretion. The IgE elevation was not ragweed specific. It correlated with proliferation of viable B cells, but not with IgE class switch. In vivo, Amb-APE increased total IgE and showed adjuvant activity in allergic airway inflammation. CONCLUSIONS Aqueous pollen extracts, the protein-free fraction of Amb-APE, and the pollen-contained substance PPE1 specifically enhance IgE production in Th2-primed B cells. Thus, pollen-derived nonallergenic substances might be responsible for B-cell-dependent aggravation of IgE-mediated allergies.

Abstract
BACKGROUND Ragweed (Ambrosia artemisiifolia) is a strong elicitor of allergic airway inflammation with worldwide increasing prevalence. Various components of ragweed pollen are thought to play a role in the development of allergic responses. The aim of this study was to identify critical factors for allergenicity of ragweed pollen in a physiological model of allergic airway inflammation. METHODS Aqueous ragweed pollen extract, the low molecular weight fraction or the major allergen Amb a 1 was instilled intranasally on 1-11 consecutive days, and allergic airway inflammation was evaluated by bronchoalveolar lavage, lung histology, serology, gene expression in lung tissue, and measurement of lung function. Pollen-derived adenosine was removed from the extract enzymatically to analyze its role in ragweed-induced allergy. Migration of human neutrophils and eosinophils toward supernatants of ragweed-stimulated bronchial epithelial cells was analyzed. RESULTS Instillation of ragweed pollen extract, but not of the major allergen or the low molecular weight fraction, induced specific IgG1 , pulmonary infiltration with inflammatory cells, a Th2-associated cytokine signature in pulmonary tissue, and impaired lung function. Adenosine aggravated ragweed-induced allergic lung inflammation. In vitro, human neutrophils and eosinophils migrated toward supernatants of bronchial epithelial cells stimulated with ragweed extract only if adenosine was present. CONCLUSIONS Pollen-derived adenosine is a critical factor in ragweed-pollen-induced allergic airway inflammation. Future studies aim at therapeutic strategies to control these allergen-independent pathways.

Abstract
Recurrent fever can be the sole or leading manifestation of a variety of diseases including malignancies, autoimmune diseases and infections. Because the differential diagnoses are manifold, no formal guidelines for the approach of patients with recurrent fever exists. The newly recognized group of autoinflammatory diseases are often accompanied by repetitive fever attacks. As these episodes are frequently associated by a variety of divergent presentations, the differentiation of other causes for febrile illnesses can be difficult. In this article, we first review disease entities, which frequently present with the symptom of recurrent fever. In a next step, we summarize their characteristic pattern of disease presentation. Finally, we analyse key features of autoinflammatory diseases, which are helpful to distinguish this group of diseases from the other causes of recurrent fever. Recognizing these symptom patterns can provide the crucial clues and, thus, lead to the initiation of targeted specific diagnostic tests and therapies.

Abstract
Urticarial skin reactions are one of the most frequent problems seen by allergists and clinical immunologists in daily practice. The most common reason for recurrent wheals is spontaneous urticaria. There are, however, several less common diseases that present with urticarial rash, such as urticarial vasculitis and autoinflammatory disorders. The latter include cryopyrin-associated periodic syndrome and Schnitzler's syndrome, both rare and disabling conditions mediated by increased interleukin-1 secretion. Apart from the urticarial rash, patients are suffering from a variety of systemic symptoms including recurrent fever attacks, arthralgia or arthritis and fatigue. Autoinflammatory diseases are often associated with a diagnostic delay of many years and do not respond to antihistamines and other treatments of urticaria. Also, the chronic inflammation may lead to long-term complications such as amyloidosis. It is therefore important not to miss these diseases when diagnosing and treating patients with chronic recurrent urticarial rash. Here, we present clinical clues and tips that can help to identify autoinflammatory disorders in patients presenting with chronic urticarial rash and discuss their clinical picture and management.

Abstract
Infection with the yeast candida is a quite common disease. Its occurrence might be harmless, however, Candida infections often present with an underlying systemic disease. Thus, candidiasis in some cases can be considered as an indicator for e.g. diabetes mellitus or immune deficiency (i.e. HIV or leukaemia). Of note, we have to distinguish the colonisation and the infection with Candida because only the presence of the yeast together with clinical symptoms is an indication for treatment. The latter has to be adapted according to age, localisation and potentially underlying systemic disease. A special form of Candidiasis constitutes the chronic mucocutaneous candidiasis which can occur in line with hereditary immune deficiencies or also isolated. In the present review we discuss the current status of diagnostic and therapy of mucocutaneous candidiasis as well as the (patho-) immunologic background of yeast infections using the example of a special case of chronic mucocutaneous candidiasis.

Abstract
BACKGROUND Evidence is accumulating that the pollen exsudate contains an array of non-allergenic, pro-inflammatory and immunomodulatory substances acting on the innate and adaptive immune system. In this context, pollen-associated E(1)-phytoprostanes (PPE(1)) were shown to licence human monocyte-derived dendritic cells for T-helper type 2 (Th2) polarization of naïve T cells. OBJECTIVE This study aims at analysing the impact of pollen-associated lipid mediators on cytokine secretion and maturation of 6-sulfo LacNAc(+) dendritic cells (slanDCs), the most abundant native dendritic cell (DC) in human peripheral blood, and further dissecting the biologically active substance(s) within aqueous pollen extracts. RESULTS Aqueous birch pollen extracts dose-dependently inhibited the lipopolysaccharide (LPS)-induced IL-12 p70 production, while the levels of IL-6 remained unaffected. PPE(1) inhibited secretion of both IL-12 p70 and IL-6. Aqueous pollen extracts, but not PPE(1) or F(1)-phytoprostanes significantly reduced the LPS-induced surface expression of the maturation markers CD80, CD83, CD40 and CCR-7, an effect that was independent of proteins and that was still present in a 3 kDa cut-off fraction of the pollen extract. These effects were observed irrespective of the atopy status of the donors. Finally, slanDCs exposed to aqueous pollen extracts were impaired in eliciting an IFN-gamma response in naïve CD4(+) T cells. CONCLUSION Our data show that slanDCs, a subset of human blood DCs with constitutively high potency to induce Th1 responses, are susceptible to the Th2 polarizing effect of low molecular weight, non-protein factors derived from pollen.

Abstract
BACKGROUND Epidemiologic studies reveal a dramatic increase in allergies in the last decades. Air pollution is considered to be one of the factors responsible for this augmentation. The aim of this study was to analyze the impact of urbanization on birch pollen. The birch pollen proteome was investigated in order to identify differences in protein abundance between pollen from rural and urban areas. The allergenicity of birch pollen from both areas was evaluated by assessing its chemotactic potency as well as its protein and allergen contents. METHODS Difference gel electrophoresis (DIGE) was used to analyze the pollen proteome. The chemotactic activity of aqueous pollen extracts was determined by migration assays of human neutrophils. RESULTS DIGE revealed 26 differences in protein spot intensity between pollen from urban and rural areas. One of these proteins was identified by de novo sequencing as the 14-3-3 protein, which resembles a stress-induced factor in other plant species. Furthermore, extracts from pollen collected in urban areas had higher chemotactic activity on human neutrophils compared to pollen from rural sites. CONCLUSIONS The present study points to an impact of air pollution on allergen carrier proteome and release of chemotactic substances. The increment in proinflammatory substances such as pollen-associated lipid mediators might contribute to the described urban-rural gradient of allergy prevalence. Furthermore, our study suggests that allergenicity is determined by more than the sole allergen content.

Abstract
BACKGROUND A pathogenic role of serine protease inhibitor lymphoepithelial Kazal type-related inhibitor (LEKTI) in atopic dermatitis (AD) is currently in intense debate. Analyses of an association between genetic polymorphisms of SPINK5 and atopic diseases revealed contradictory results. Herein, we assessed the role of LEKTI in AD at an expressional and functional level. METHODS The expression of LEKTI and its inhibitory capacity was measured by real-time polymerase chain reaction and hydrolytic activity assay, respectively, in keratinocyte cell cultures of three AD patients in comparison to cultures of healthy individuals (5x) and Netherton (NS) patients (3x). RESULTS Expression of LEKTI was significantly decreased in AD vs. healthy volunteers. Due to reduced protease inhibition, trypsin-like hydrolytic activity in AD was slightly increased, although not significantly. CONCLUSIONS Even though the number of investigated subjects was small and hydrolytic activity was only slightly increased, the results denote that LEKTI might be diminished in AD. The study also disclosed the necessity of functional analyses in addition to genetic investigations to gain further and more detailed insights into the role of LEKTI in AD.

Abstract
BACKGROUND Desloratadine is an H1-histamine antagonist which possesses additional anti-inflammatory properties through inhibition of leukocyte activation and reduction of ICAM-1 expression on mucosal epithelial cells. So far no studies have addressed the potential anti-inflammatory activities of desloratadine and loratadine on skin keratinocytes. OBJECTIVE In this study the capacity of desloratadine and loratadine to counteract human keratinocyte activation by interferon-gamma (IFN-gamma) was analyzed. In particular, the chemokine release of kerationcytes and the crosstalk between keratinocytes and lymphocytes were examined. METHOD Keratinocyte cultures established from normal skin of healthy donors were activated by IFN-gamma in the absence or presence of desloratadine and loratadine, and tested for the release of CCL5/RANTES, CXCL8/IL-8, CCL17/TARC and CXCL10/IP-10. Furthermore the supernatants of differentially stimulated keratinocytes were used for migration studies of human neutrophils, eosinophils and polarized Th1/Th2 clones. RESULTS Desloratadine and loratadine inhibited the constitutive and IFN-gamma-induced release of CCL5, CXCL8 and CXCL10 from keratinocytes, while the low release of CCL17 remained unchanged. Furthermore the crosstalk between lymphocytes and keratinocytes was blocked as shown by a reduced capacity of desloratadine/loratadine-stimulated keratinocytes to attract human neutrophils, eosinophils and T cells. CONCLUSIONS The results indicate that desloratadine has the capacity to block the IFN-gamma-induced activation of keratinocytes, and that it can thus exert important regulatory effects on cell-mediated immune responses in the skin. The rather high doses required for these effects argue for a topical application when trying to use desloratadine in epidermal inflammatory conditions.

Abstract
Since seven years, the 23-year-old woman suffered from severe dysphagia and cutaneous Candida-granulomas on the right side of the head, the nose and both hands. The therapy with different oral antimycotics was ineffective. Intravenously and orally administered high-dose fluconazole has induced healing of the mucocutaneous lesions. The esophageal stenosis, most likely caused by esophageal candidosis, was found as the origin of dysphagia. It was successfully treated by fluconazole and endoscopic dilatations.
