Background: There are conflicting data on a potential association between obesity and atopic dermatitis (AD). The purpose of this study was to investigate the relationship between obesity and AD disease severity. Methods: Patients from the TREATgermany registry cohort were divided into three groups according to their body mass index (BMI). Due to low numbers, underweight patients (BMI <18.5 kg/m2) were excluded from the analysis. Physician‐ and patient‐reported disease severity scores as well as additional phenotypic characteristics were evaluated for association with BMI. Generalized linear mixed models and multinomial logit models, respectively, were applied to investigate the association of BMI, age, sex and current systemic AD treatment with disease severity. Results: This study encompassed 1416 patients, of which 234 (16.5%) were obese (BMI ≥30 kg/m2). Obesity was associated with lower educational background and smoking. Otherwise, obese and non‐obese AD patients had similar baseline characteristics. Increased BMI was associated with higher oSCORAD (adjusted β: 1.24, 95% CI: 1.05–1.46, p = 0.013) and Patient‐oriented eczema measure (POEM) (adjusted β: 1.09, 95% CI: 1.01–1.17, p = 0.038). However, the absolute difference in the overall oSCORAD was small between obese and non‐obese AD patients (Δ oSCORAD = 2.5). Allergic comorbidity was comparable between all three groups, with the exception of asthma which was more pronounced in obese patients (p < 0.001). Discussion: In this large and well‐characterized AD patient cohort, obesity is significantly associated with physician‐ and patient‐assessed measures of AD disease severity. However, the corresponding effect sizes were low and of questionable clinical relevance. The overall prevalence of obesity among the German AD patients was lower than in studies on other AD cohorts from different countries, which confirms previous research on the German population and suggests regional differences in the interdependence of AD and obesity prevalence.

TREATgermany is an investigator-initiated prospective disease registry. It investigates physician- and patient-reported disease severity (Eczema Area and Severity Index (EASI), objective Scoring Atopic Dermatitis (oSCORAD), Investigator Global Assessment, Patient-Oriented Eczema Measure (POEM), Patient Global Assessment (PGA)), patient-reported symptoms (itch, sleep loss, depressive symptoms), therapy courses and dermatological quality of life (DLQI) in moderate-to-severe atopic dermatitis with SCORAD > 20. 1,134 atopic dermatitis patients (mean age 41.0 ± 14.7 years, 42.5% females) were enrolled by 40 German recruiting sites (dermatological clinics and practices) between June 2016 and April 2021. The current analysis focuses on itch scores obtained with a numerical rating scale (NRS)) documented for the previous 3 days prior to baseline visit. The results show that 97.2% (1,090 of 1,121) patients experienced itch. Itch severity correlated moderately with severity of atopic dermatitis oSCORAD (rho = 0.44 (0.39–0.48)) and EASI score (rho = 0.41 (0.36–0.46)). A strong correlation was found with self-reported disease severity as PGA (rho = 0.68 (0.65–0.71)), POEM sum score (rho = 0.66 (0.63–0.69)) and dermatological quality of life impairment DLQI (rho = 0.61 (0.57–0.65)). Itch as a subjective complaint is more closely correlated with patient-reported outcomes than with objective assessments by the physician.

This article examines the real-world use and effectiveness of baricitinib, a small molecule inhibitor, for the treatment of moderate-to-severe atopic dermatitis (AD). The study, conducted in the TREATgermany registry with over 1600 patients, found that a majority of patients had previously tried other systemic therapies before using baricitinib. The results showed that after 3 months of treatment, there was a positive response in terms of disease severity, and the treatment was well-tolerated. The study was supported by various pharmaceutical companies, and the authors acknowledge the contributions of patients, physicians, clinical staff, and the TREATgermany Study Group.

The article discusses a study conducted in Germany that examined the use of dupilumab, a biologic treatment, for pediatric patients with moderate-to-severe atopic dermatitis (AD). The study found that dupilumab significantly improved disease severity and quality of life in these patients. The treatment was generally well-tolerated, with only a few reported adverse events. The study also analyzed biomarkers and found that certain proteins showed differential expression in lesional versus non-lesional skin, but it is unclear if the protein levels reached those of non-AD skin. The authors suggest that larger and longer-term studies are needed to further evaluate the effects of systemic therapies in pediatric AD. [Extracted from the article]

Background: Mainly women work as foot care specialists (FCS). They are at risk to develop occupational dermatitis (OD). Objectives: The objective of this study is to describe the contact sensitisation pattern of female FCS with OD. Methods: In a retrospective study, patch test and clinical data collected by the Network of Departments of Dermatology (IVDK) from 2008 to 2022 were analysed. Data of 116 female FCS with OD were compared with data of 13 930 female patients with OD working in other professions and 78 612 female patients without OD. Results: Hand dermatitis (93.1%) was significantly more common and face dermatitis (0.9%) significantly less common in female FCS with OD compared to other female patients with or without OD. Frequent suspected allergen sources were disinfectants, gloves, leave‐on and nail cosmetics. Occlusion and wetness were important co‐factors. The most common diagnoses were irritant contact dermatitis (26.7%) and allergic contact dermatitis (21.6%). No sensitisation to any of the baseline series allergens was significantly more frequent in female FCS with OD than in the two control groups. However, sensitisations to allergens which FCS are abundantly exposed to, including fragrances, preservatives, rubber ingredients and disinfectants, were most common. Conclusions: FCS should be aware of the OD risk and prevention should be promoted. [ABSTRACT FROM AUTHOR]

Background Concerns regarding contact allergies and intolerance reactions to dental materials are widespread among patients. Development of novel dental materials and less frequent amalgam use may alter sensitization profiles in patients with possible contact allergy. Objectives To analyse current sensitization patterns to dental materials in patients with suspected contact allergy. Methods This retrospective, multicentre analysis from the Information Network of Departments of Dermatology (IVDK) selected participants from 169 834 people tested in 2005–2019 and registered with (i) an affected area of 'mouth' (and 'lips'/'perioral'), (ii) with the dental material in question belonging to one of three groups (dental filling materials, oral implants or dentures or equivalents) and (iii) with patch-testing done in parallel with the German baseline series, (dental) metal series and dental technician series. Results A total of 2730 of 169 834 tested patients met the inclusion criteria. The patients were predominantly women (81.2%) aged ≥ 40 years (92.8%). The sensitization rates with confirmed allergic contact stomatitis in women (n = 444) were highest for metals (nickel 28.6%, palladium 21.4%, amalgam 10.9%), (meth)acrylates [2-hydroxyethyl methacrylate (HEMA) 4.8%] and the substances propolis (6.8%) and 'balsam of Peru' (11.4%). The most relevant acrylates were HEMA, 2-hydroxypropyl methacrylate, methyl methacrylate, ethylene glycol dimethacrylate and pentaerythritol triacrylate. Few men were diagnosed with allergic contact stomatitis (n = 68); sensitization rates in men were highest for propolis (14.9%) and amalgam (13.6%). Conclusions Allergic contact stomatitis to dental materials is rare. Patch testing should not only focus on metals such as nickel, palladium, amalgam and gold, but also (meth)acrylates and the natural substances propolis and 'balsam of Peru'. [ABSTRACT FROM AUTHOR]

Summary: The present S3 guideline was created based on the European English‐language S3 guideline, with special consideration given to the medical conditions in the German‐speaking region, and with additions from the previous German‐language version, in accordance with the criteria of the AWMF. This second part of the guideline addresses the systemic therapy of atopic dermatitis (AD). It covers topics such as the indication for systemic therapy in children, adolescents, and adult patients with AD. Furthermore, it addresses all medications approved for AD, such as the biologics dupilumab and tralokinumab, the Janus kinase inhibitors abrocitinib, baricitinib, and upadacitinib, as well as conventional immunosuppressive therapies with systemic glucocorticosteroids and ciclosporin. Additionally, it discusses systemic off‐label therapies. The first part of the guideline, published separately, includes the definition and diagnostic aspects of AD, describes topical therapy, non‐drug therapy approaches, and addresses aspects related to special patient groups.

Background: The German S2k guideline is the first to include a checklist that captures atopic dermatitis (AD) signs and symptoms as well as the lack of treatment response to identify patients eligible for systemic therapy. Objectives: Identifying candidates for a start/switch of systemic therapy in adult AD patients in Germany by applying the S2k guideline's checklist. Methods: In this German multicentre, cross‐sectional, non‐interventional study (German Clinical Trials Register number: DRKS00023296), adult patients with mild to severe AD were enrolled at dermatological outpatient clinics and offices between April and October 2021. Demographics, clinical characteristics and quality of life were collected using questionnaires during one single visit. Eligibility for a start/switch of systemic AD therapy was evaluated according to the criteria of the German S2k guideline's checklist. Results: Atopic dermatitis patients (575) were included in the analysis. One hundred and sixty‐four patients (28.5%) received systemic (SYS) AD therapy and 411 patients (71.5%) did not (TOP). Of the TOP therapy patients, 38.7% were eligible to start systemic AD therapy, and about half of those (49.1%), were scheduled to start systemic AD therapy. The most frequent reason deciding against a systemic therapy was the patient's wish. Although 29.3% of SYS patients were eligible for a switch according to the criteria of the German S2k guideline's checklist, the majority (81.3%) did not switch AD therapy. Conclusions: This is the first study on the implementation of the German S2k guideline's checklist in everyday care of AD patients in Germany. More than one‐third of the TOP patients were identified as eligible for systemic treatment. By applying the guideline's checklist criteria, another one‐third of SYS patients may have benefited from a change of current systemic therapy. The use of the German S2k guideline's checklist in routine care represents an important tool to ensure effective patient care and identify inadequately treated patients. [ABSTRACT FROM AUTHOR]

Summary: Background: TREATgermany is a multicenter registry including patients with moderate‐to‐severe atopic dermatitis (AD) from currently 74 study centers (university clinics, hospitals and practices) in Germany. As of August 31, 2021, 1,230 adult patients were enrolled. Methods: In TREATgermany, patients and physicians fill in questionnaires pertaining to symptoms, disease severity, quality of life, depressiveness, and fatigue. In particular, limitations in work performance are assessed using the Work Limitations Questionnaire (WLQ). To assess associations between occupational performance/work limitations and symptoms, correlations and regression models were calculated. Results: The examined sample of 228 employed patients reported an average of 6% at‐work productivity loss within the past two weeks prior to enrolment in the registry. The WLQ productivity loss score was moderately associated with itch (r = 0.32) and sleep loss (r = 0.39) and strongly associated with depressive symptoms (r = 0.68) and fatigue (r = 0.60). Conclusions: The analyses of the registry data show that moderate‐to‐severe atopic dermatitis has a negative impact on the work productivity of the patients. The analyses further point out the relevant associations between work productivity, depressive symptoms, and fatigue highlighting the disease burden caused by the psychological components of AD.

Background: Atopic dermatitis (AD) patients display an altered skin microbiome which may not only be an indicator but also a driver of inflammation. We aimed to investigate associations among AD patients' skin microbiome, clinical data, and response to systemic therapy in patients of the TREATgermany registry. Methods: Skin swabs of 157 patients were profiled with 16S rRNA gene amplicon sequencing before and after 3 months of treatment with dupilumab or cyclosporine. For comparison, 16s microbiome data from 258 population‐based healthy controls were used. Disease severity was assessed using established instruments such as the Eczema Area and Severity Index (EASI). Results: We confirmed the previously shown correlation of Staphylococcus aureus abundance and bacterial alpha diversity with AD severity as measured by EASI. Therapy with Dupilumab shifted the bacterial community toward the pattern seen in healthy controls. The relative abundance of Staphylococci and in particular S. aureus significantly decreased on both lesional and non‐lesional skin, whereas the abundance of Staphylococcus hominis increased. These changes were largely independent from the degree of clinical improvement and were not observed for cyclosporine. Conclusions: Systemic treatment with dupilumab but not cyclosporine tends to restore a healthy skin microbiome largely independent of the clinical response indicating potential effects of IL‐4RA blockade on the microbiome.
