ABSTRACT
BACKGROUND: Dermatological research has traditionally concentrated on evaluating mental comorbidities, neglecting positive concepts like happiness. Initial studies indicate that psoriasis and atopic dermatitis (AD) impair the happiness of those affected. Considering global happiness variations, this study aimed to explore the disease- and country-specific differences in disease-related quality of life and happiness, and potential influential factors on heuristic happiness among psoriasis and AD patients in Europe. METHODS: A cross-sectional multicentre study was conducted in dermatology departments of university-affiliated hospitals in eight European countries (Austria, Germany, Italy, Malta, Poland, Portugal, Romania and Ukraine) between October 2021 and February 2023. Adult psoriasis and AD patients completed a standardized questionnaire in their native languages, providing data on demographics, disease-related characteristics, disease-related quality of life (Dermatology Life Quality Index, DLQI), heuristic happiness, positive affect (PA), negative affect (NA) and satisfaction with life (SWL). Descriptive analysis and quantile regression were performed. RESULTS: Between psoriasis (n = 723) and AD (n = 316) patients almost no differences were observed in happiness, SWL and NA, except for DLQI and small differences in PA, with AD patients reporting greater impact than psoriasis patients. Country-wise variation emerged in DLQI, heuristic happiness, PA, NA and SWL with Austrian patients displaying the highest levels of happiness, satisfaction and positivity, coupled with higher treatment care and lower disease severity. Quantile regression revealed varying coefficients for predictor variables across quantiles, indicating, for example positive effects on heuristic happiness associated with current or previous receipt of systemic therapies at different quantiles. CONCLUSION: This study shows notable happiness differences across European countries and significant disease-related variations, particularly with AD patients being more impaired than psoriasis patients. The findings highlight the need for equality in treatment access and support the development of targeted positive psychological interventions to enhance happiness considering country-specific distinctions in future research and health policies for psoriasis and AD patients.
ABSTRACT
BACKGROUND: Atopic dermatitis (AD), which can significantly impact quality of life, is a complex, heterogeneous skin disease affecting all ages and therefore can lead to very different patient journeys. Understanding the patient journey within the healthcare system is essential for improving care outcomes. OBJECTIVES: To explore the patient journey of individuals with AD in Germany, with a specific focus on the utilization of Internet resources throughout this process. METHODS: A cross-sectional study using a self-administered questionnaire was conducted from June 2021 to February 2022. Participants were recruited from dermatology private practices, a university hospital and online platforms. RESULTS: The study included 276 participants (62.3% female; mean age: 46.3 ± 18.4 years; mean disease duration: 26.9 ± 17.5 years; mean DLQ Index: 10.0 ± 5.6). Around 191 participants were currently receiving medical treatment, with 9.1% receiving biologic therapy. Most of the people initially contacted a GP (42.4%) and were diagnosed by a dermatologist first (57.6%). Around 47.1% were currently in treatment by a dermatologist, seeking dermatological care on average 4.5 times a year. Almost all individuals (86.2%) have already consulted more than one physician during their patient journey. Overall, participants consulted a median of five physicians, while those with severe AD consulted a median of six physicians. Initial symptoms to diagnosis and between consulting two different physicians both had a median duration of 6 months. Dissatisfaction with treatment outcomes emerged as a common reason for changing physicians. Approximately 76.4% of participants used the Internet for disease-related information, primarily relying on Google. Overall, 63% found the information quality unsatisfactory. CONCLUSION: The study underlines the widespread utilization of medical treatment and the proactive healthcare-seeking behaviour during a long patient journey. Dissatisfaction with treatment outcomes, alternative medicine and the quality of the Internet sources emphasize the potential for improving the comprehensive disease management to improve care outcomes.
ABSTRACT
Gender- and sex-specific differences in medicine were long-time disregarded. Despite numerous indications of gender- and sex-specific influences on the treatment of dermatological conditions, these have not yet been systematically investigated. To meet this unmet need, we conducted the present systematic review on the topic of gender and sex differences in the treatement outcome of skin diseases. Embase (via Ovid), PubMed Medline and Web of Science were searched, in between January 2001 and December 2022. English and german randomized controlled trials, prospective and retrospective cohorts and case-control studies that examined differences between men and women in treatment outcomes of skin diseases were included. Two authors independently screened the reports for eligibility, one extracted all data (the second double-checked) and critically appraised the quality and risk of bias of the studies. Eighty-three reports were included. The largest share of the identified publications focused on gender differences in psoriasis and psoriatic arthritis (n = 49), followed by melanoma (n = 8) and sporadic studies (n < 5) of inflammatory, infectious and autoimmune skin diseases. The main topics in which gender differences could be identified were choice of treatment, time to initiation of treatment, therapy response, adverse events, adherence and treatment satisfaction. For psoriasis, gender differences could be found in all aspects, while for the other skin diseases specific publications on gender differences are still missing. This systematic review shows numerous gender differences but also reveals major gaps in gender-specific care in dermatology which should be narrowed in the upcoming years to optimize a patient-centred, individualized, gender-equal healthcare.

ABSTRACT
BACKGROUND: Hailey-Hailey disease (HHD) remains a difficult-to-treat dermatosis and little is known about the patient's perception of the disease activity, the treatment success and its impact on quality-of-life (QoL). OBJECTIVE: To obtain better understanding of HHD patients' needs regarding their medical condition, financial burden, QoL, subjective well-being and treatment thereof as well as satisfaction to evaluate common treatments' 'real-life' relevance. METHODS: With initiation of the national registry for Darier's disease (DD; Morbus Darier, MD) and Hailey-Hailey disease (HH) MDHHgermany, patients with HHD diagnosis were included starting June 2020. To assess subjective symptoms, patients filled out questionnaires such as the DLQI (dermatological life quality index), numeric rating scale (NRS) for itch, pain and burning sensation, as well as the SWLS (satisfaction with life scale) questionnaire to quantify overall satisfaction in life. Additionally, data on therapies were collected along with the patients' satisfaction of those and their medical care. Furthermore, patients assessed financial aspects and work ability. RESULTS: One hundred and two patients were recruited from dermatology clinics, office-based dermatologists and self-help platforms across Germany between June 2020 and February 2023, 90 were eligible and analysed (mean: 49.91 years, 73.33% females, 26.67% males). 39.77% stated according to the DLQI their life is severely/very severely affected. Satisfaction with life was mediocre. Burning sensation was most pronounced among subjective symptoms (NRS 5.85 ± 2.80). Systemic treatments were rated as ineffective according to 56.92%, 25.56% had never received one. Most prescribed systemic treatments were corticosteroids (73.8%), followed by low-dose naltrexone (LDN) (26.2%), retinoids (15.4%) and antibiotics (13.8%). Satisfaction with medical care was generally low. CONCLUSION: Our 'real-life' data state a major disease burden and impact on the QoL for affected individuals, as well as limited disease control due to inadequate therapies. MDHHgermany can provide insights into improvement of healthcare support with this debilitating disease and improve QoL. In the long term, it aims to provide basis for further clinical trials, epidemiological studies and immunological investigations.

Atopic dermatitis (AD) is the most common chronic inflammatory skin disease worldwide. Its severity is assessed using scores that rely on visual observation of the affected body surface area, the morphology of the lesions and subjective symptoms, like pruritus or insomnia. Ideally, such scores should be complemented by objective and accurate measurements of disease severity to standardize disease scoring in routine care and clinical trials. Recently, it was shown that raster-scanning optoacoustic mesoscopy (RSOM) can provide detailed three-dimensional images of skin inflammation processes that capture the most relevant features of their pathology. Moreover, precise RSOM biomarkers of inflammation have been identified for psoriasis. However, the objectivity and validity of such biomarkers in repeated measurements have not yet been assessed for AD. Here, we report the results of a study on the repeatability of RSOM inflammation biomarkers in AD to estimate their precision. Optoacoustic imaging analysis revealed morphological inflammation biomarkers with precision well beyond standard clinical severity metrics. Our findings suggest that optoacoustic mesoscopy may be a good choice for quantitative evaluations of AD that are inaccessible by other methods. This could potentially enable the optimization of disease scoring and drug development.
ABSTRACT
BACKGROUND: Vaccination of the population is required to combat the COVID-19 pandemic. Allergy testing could reduce anxiety towards COVID-19 vaccination and thereby may increase vaccination rate, however, its effectiveness remains unclear. METHODS: One hundred and thirty prospective real-life patients in need of but not daring to get vaccinated asked for allergy workup for COVID-19 vaccine hypersensitivity in 2021/2022. Characterization of patients, identification of anxieties, decrease of patient's anxiety levels, overall vaccination rate and adverse reactions after vaccination were assessed. RESULTS: Tested patients were characterized by being female (91.5%) and having a high rate of previous allergies (e.g. to food 55.4%, drugs 54.6%, or previous vaccinations 50%) and dermatological disease (29.2%) but not always had medical contraindications for COVID-19 vaccination. Sixty one patients (49.6%) were highly concerned (4-6, Likert scale 0-6) about vaccination and 47 (37.6%) expressed resolving thoughts about vaccinaion anaphylaxis (3-6, Likert scale 0-6). However only 35 patients (28.5%) were scared of getting COVID-19 within 2 months (4-6, Likert scale 0-6) and only 11 (9%) patients had high expectations of getting COVID-19 (4-6, Likert scale 0-6). Allergy testing significantly (p < 0.01 to p < 0.05 respectively) reduced the median anxiety of allergic symptoms following vaccination: dyspnoea (4.2-3.1), to faint (3.7-2.7), long-term consequences (3.6-2.2), pruritus (3.4-2.6), skin rash (3.3-2.6) and death (3.2-2.6). After allergy testing, most patients (108/122, 88.5%) let themselves be vaccinated within 60 days. Revaccinated patients with previous symptoms experienced a reduction of symptoms (p < 0.05) upon revaccination. CONCLUSIONS: Patients not daring to get vaccinated have more anxiety towards vaccination than to acquire COVID-19. For those, allergy testing excludes vaccine allergy, and is a tool to increase vaccination willingness and thereby helps to combat vaccination hesitancy.

Abundant heterogeneous immune cells infiltrate lesions in chronic inflammatory diseases and characterization of these cells is needed to distinguish disease-promoting from bystander immune cells. Here, we investigate the landscape of non-communicable inflammatory skin diseases (ncISD) by spatial transcriptomics resulting in a large repository of 62,000 spatially defined human cutaneous transcriptomes from 31 patients. Despite the expected immune cell infiltration, we observe rather low numbers of pathogenic disease promoting cytokine transcripts (IFNG, IL13 and IL17A), i.e. >125 times less compared to the mean expression of all other genes over lesional skin sections. Nevertheless, cytokine expression is limited to lesional skin and presented in a disease-specific pattern. Leveraging a density-based spatial clustering method, we identify specific responder gene signatures in direct proximity of cytokines, and confirm that detected cytokine transcripts initiate amplification cascades of up to thousands of specific responder transcripts forming localized epidermal clusters. Thus, within the abundant and heterogeneous infiltrates of ncISD, only a low number of cytokine transcripts and their translated proteins promote disease by initiating an inflammatory amplification cascade in their local microenvironment.

BACKGROUND: Cutaneous lesions of mastocytosis (CLM) are often subtle and may require biopsy. However, dermatohistopathological criteria for CLM remain undefined. OBJECTIVES: To establish criteria for CLM by validating histological and molecular parameters. METHODS: In skin samples from Caucasian patients with CLM and controls (atopic dermatitis, chronic urticaria, pruritus, tissue from tumor safety margin excisions), mast cell (MC) numbers, size, shape, distribution, immunostainability with a large panel of markers, pigmentation and presence of KIT D816V mutation were analysed. RESULTS: Forty-seven CLM patients (32 maculopapular cutaneous mastocytosis (MPCM), 15 mastocytomas) and 36 controls were included. Mastocytomas were easily identified by densely packed cuboidal MCs. In MPCM, skin MC density in CD117 stains was higher in CLM patients than in controls (P < 0.0001) and values correlated closely (r = 0.65, P < 0.0001) to results in tryptase stains. The optimized upper dermis cut-off number of 62 MC/mm2 had a sensitivity and specificity of 92% in both stainings, corresponding to approximately 12 MC/high power field (HPF). MC size was larger in MPCM than in controls (P = 0.01). Interstitial (= not perivascular or periadnexal) MCs and stronger basal pigmentation of the epidermis were indicative of MPCM (P < 0.0001 each) and clusters of >3 nucleated MC/HPF exclusively found in MCPM. Surface markers CD2, CD25 and CD30 stained T-lymphocytes, but only negligibly CLM MC. The KIT D816V mutation in formalin fixed paraffin embedded (FFPE) skin was evaluable in 87.5% of MCPM patients and had both 100% sensitivity and specificity. CONCLUSIONS: MPCM can be predicted by major and minor criteria combined in a scoring model. Presence of D816V mutation in FFPE skin and MC density > 27/HPF are >95%-specific major criteria for MPCM. MC densities 12/HPF, interstitial MC, clusters and basal pigmentation are minor criteria.

BACKGROUND: Cutaneous bacterial dysbiosis is a characteristic hallmark of atopic dermatitis (AD), and it decisively influences the severity of the disease. Despite this, frequently used murine models of AD have not been characterized regarding the changes in skin microbiome communities. OBJECTIVE: To analyse the skin microbiome of two frequently used murine models for AD for assessing their applicability in translational research. METHODS: AD was induced in mice by topical application of calcipotriol or oxazolone. Following comparable elicitation of AD-like dermatitis, including IgE induction, the skin microbial communities were analysed and compared with human AD. RESULTS: We detected critical differences in the microbiota composition of diseased skin. In contrast to calcipotriol treatment, application of oxazolone induced significant changes in the cutaneous microbiota and a drastic drop of bacterial richness. Furthermore, an expansion of Staphylococci, particularly S. xylosus, was observed in the oxazolone group, also displaying positive correlations with AD key markers including pH, TEWL, IL-4, TSLP and IL-33. CONCLUSIONS: In this article, we show that (a) the model of choice to investigate AD needs to be characterized for the cutaneous microbiota if applicable and (b) the oxazolone-mediated mixed Th1-Th2 immune response triggers microbiota-induced alterations which share similarities to dysbiosis in human AD and represents therefore a suitable model for translational research on AD if alterations of the microbiome are in the focus of the investigation.

BACKGROUND: Atopic dermatitis (AD) is a chronic inflammatory skin disease with a multifactorial genesis including genetic predispositions and environmental risk and trigger factors. One of the latter possibly is smoking, indicated by an increased prevalence of AD in adults and children that are actively or passively exposed to cigarette smoke. OBJECTIVES: In this study, AD characteristics and its atopic comorbidities are compared in smoking and non-smoking AD patients. METHODS: TREATgermany is a non-interventional clinical registry which includes patients with moderate to severe AD in Germany. Baseline data of patients included in TREATgermany from inception in June 2016 to April 2020 in 39 sites across Germany was analysed comparing AD disease characteristics and comorbidities in smokers vs. non-smokers. RESULTS: Of 921 patients, 908 (male: 58.7%) with a mean age of 41.9 ± 14.4 reported their smoking status. The objective Scoring of Atopic Dermatitis (oSCORAD) did not differ between smokers (n = 352; 38.8%) and non-smokers, however, lesions' intensity of oozing/crusts and excoriations as well as patient global assessment scores (PGA) of AD severity were higher in smoking as opposed to non-smoking patients. Smokers reported a lower number of weeks with well-controlled AD and more severe pruritus than non-smokers. Total IgE levels were more elevated in smokers and they displayed a younger age at the initial diagnosis of bronchial asthma. After adjustment for potential confounders, the increased intensity of oozing/crusts, the reduced number of weeks with well-controlled AD and the greater pruritus remained different in smokers compared to non-smokers. In addition, smoking patients with adult-onset AD showed a 2.5 times higher chance of involvement of the feet. CONCLUSIONS: German registry data indicate that AD patients who smoke have a higher disease burden with a different distribution pattern of lesions in adult-onset AD.

BACKGROUND: Atopic dermatitis (AD) is the most common chronic inflammatory skin disease worldwide and displays many atopic, but also non-atopic comorbidities. Among the latter, mental health disorders such as depression have been extensively studied. However, data on addictions are still rare. OBJECTIVES: The aim of this study was to assess the prevalence of different kinds of addictions in adult AD patients using a single-centre approach. METHODS: This non-interventional cross-sectional study was performed from 03/2020 to 05/2020 at the Department of Dermatology of a large German university hospital. Participants with a diagnosis of AD confirmed by a dermatologist answered questions about disease severity (patient-oriented eczema measure, POEM), quality of life (Dermatology Life Quality Index, DLQI) and smoking habits. They were screened for problematic alcohol consumption, drug abuse, internet addiction and pathological gambling using internationally established and validated questionnaires. RESULTS: 157 patients (56.1% female; mean age of 49.9 ± 20.4) with an average POEM of 13.7 ± 7.5 and DLQI of 6.1 ± 5.4 were evaluated. 14.1% were identified as regular smokers, 12.1% screened positive for alcohol dependency, 6.4% for drug use disorders, 4.5% for Internet addiction and 3.2% for pathological gambling. Co-occurrences of different addictions were observed, and a positive correlation was noted between DLQI scores and smoking. CONCLUSIONS: In summary, this study hints at elevated positive screening rates for problematic alcohol consumption, drug use disorders, Internet addiction and problem gambling compared with the general population. Screening routinely for addictions may improve patient-centred health care of AD patients.

Optoacoustic imaging (OAB) has developed steadily in recent years. By means of partly pulsed light, in a wide variety of wavelengths, different colour carriers (chromophores) are excited to form sound waves. These in turn are detected by the newly developed systems and converted into three-dimensional images by means of various algorithms. The technique is characterised by a good ratio between contrast and penetration depth and can create macro-, meso- and microscopic images due to its scalability. Optoacoustic macroscopy broadly irradiates the area to be examined with laser light. This can produce images with a high penetration depth, but only with a moderate resolution. Clinically interesting fields of application are for example the results of sentinel lymph nodes (SLNs) examined ex vivo using macroscopic optoacoustics. Due to the ability of OAB to visualise melanin, the detection rate of metastases was superior to previous methods, but not to histology. The ability to visualise dermal and epidermal structures, especially vessels, with good resolution makes optoacoustic mesoscopy useful in the examination of inflammatory skin diseases and could contribute to the verification of the success of therapy, e.g., with biologics for psoriasis vulgaris or atopic eczema (AE), in the future. Optoacoustic microscopy, which has so far been limited mainly to preclinical in vivo research, could be used in the future to detect even finer vascular structures and their changes. The clinical possibilities of OAB seem to be of great benefit and continue to be the subject of intensive research.
