Introduction: Involvement of the scalp is common in psoriasis and severely affects the quality of life of those affected. It is difficult to treat and places special demands on the galenics of a drug formulation. Tacrolimus is a calcineurin inhibitor and is approved as an ointment formulation for the treatment of atopic dermatitis. The efficacy and safety of topically applied tacrolimus have also been studied and proven for psoriasis. However, no proprietary pharmaceutical product is currently approved for this indication. Methods: A multicenter, double-blind, vehicle-controlled phase 3 study was conducted to evaluate the efficacy and safety of 0.1% tacrolimus microemulsion when applied topically twice daily in 128 patients independently of sex with scalp psoriasis. Results: The primary efficacy analysis showed a scalp Investigator Global Assessment (s-IGA) of 0 (absence of disease) or 1 (very mild disease) at 8 weeks in 28.6% of subjects in the tacrolimus group, indicating a significantly better response (p = 0.0476, chi-square test) versus 12.7% of subjects in the placebo group (difference of 15.9%-points). The Dermatology Life Quality Index (DLQI) improved over time and was more pronounced in the group treated with tacrolimus-containing microemulsion than in the placebo group, but showed no statistically significant difference after 8 weeks of use (p = 0.193, ANCOVA). The safety analysis revealed no evidence of cutaneous side effects other than those known. Toxicologically relevant serum levels of tacrolimus could be excluded. Conclusion: The study data show that 0.1% tacrolimus microemulsion has good efficacy and safety in the treatment of scalp psoriasis. [ABSTRACT FROM AUTHOR]

Summary: Background: Eczema herpeticum (EH) is a disseminated skin infection caused by herpes simplex virus in atopic dermatitis (AD) patients. The frequency of EH and the clinical features of EH patients have not yet been investigated in a larger cohort. Methods: We sought to investigate the TREATgermany cohort, a multicenter, non‐interventional clinical registry of moderately to severely affected AD patients in Germany. Baseline characteristics of patients included between December 2017 and April 2021 were compared between patients without, single, and multiple EH. Results: Of the 893 patients, 195 (21.8%) had at least one EH. Of the 195 patients with EH, 107 had multiple EH (54.9%), representing 12.0% of the total study population. While there were no differences in demographic characteristics, previous treatment, and disease scores at enrollment (itch, IGA, oSCORAD, EASI), patients with EH had more frequent atopic comorbidities and sensitizations to house dust mite, food, and mold. Discussion: TREATgermany registry data suggest a high prevalence and recurrence rate of EH, while there appears to be no specific clinical phenotype, besides an increase in allergies, to identify EH patients in the daily routine.

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.

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. [ABSTRACT FROM AUTHOR]

Few studies have analyzed the blood transcriptome in atopic dermatitis (AD). We explored blood transcriptomic features of moderate to severe AD. Blood messenger RNA sequencing on 60 adults from the TREATgermany registry including 49 patients before and after dupilumab treatment, as well as from an independent cohort of 31 patients and 43 controls was performed. Patient clustering, differential expression, correlation and coexpression network analysis, and unsupervised learning were conducted. AD patients showed pronounced inflammatory expression signatures with increased myeloid and IL-5–related patterns, and clearly segregated into 2 distinct clusters, with striking differences in particular for transcripts involved in eosinophil signaling. The eosinophil-high endotype showed a more pronounced global dysregulation, a positive correlation between disease activity and signatures related to IL-5 signaling, and strong correlations with several target proteins of antibodies or small molecules under development for AD. In contrast, the eosinophil-low endotype showed little transcriptomic dysregulation and no association between disease activity and gene expression. Clinical improvement with receipt of dupilumab was accompanied by a decrease of innate immune responses and an increase of lymphocyte signatures including B-cell activation and natural killer cell composition and/or function. The proportion of super responders was higher in the eosinophil-low endotype (32% vs 11%). Continued downregulation of IL18RAP , IFN G, and granzyme A in the eosinophil-high endotype suggests a residual disturbance of natural killer cell function despite clinical improvement. AD can be stratified into eosinophilic and noneosinophilic endotypes; such stratification may be useful when assessing stratified trial designs and treatment strategies. [ABSTRACT FROM AUTHOR]

Introduction/Background Tralokinumab is a high-affinity, fully human IgG4 monoclonal antibody that specifically targets interleukin-13, a key driver of atopic dermatitis (AD) disease progression. Clinical trials have shown that tralokinumab is efficacious in patients with moderate-to-severe AD and has a favorable safety profile, including a low frequency of adverse events such as conjunctivitis. Management of patients in routine clinical practice differs from those enrolled in clinical trials due to strict protocol criteria, and there is a lack of clinical data on tralokinumab use in the real-world setting. Objectives: TRACE is a real-world study in patients with AD, aiming to better understand the effectiveness, safety, and clinical use of tralokinumab in daily practice. Here, we describe baseline characteristics from the first patients enrolled into TRACE in Germany. Methods: TRACE is an observational, prospective, single-cohort study of adult patients with moderate-to-severe AD who are treated with tralokinumab, according to national approved labels. Eleven countries are participating in the study across Europe, North America and the Middle East. The primary objective is to assess changes in clinical signs and symptoms of AD in tralokinumab-treated patients. Secondary objectives are to investigate safety, quality of life, patient-reported outcomes and treatment adherence, among others. Results: Of the first 100 patients initiated on tralokinumab, the mean age (standard deviation [SD]) was 44.7 years (17.9) and 58% were male. Most patients had moderate-to-severe AD with a mean Investigator's Global Assessment (IGA) score of 3.5 (SD 0.7) and mean Eczema Area and Severity Index (EASI) of 22.5 (SD 12.9). Patients reported heavy symptomatic burden of disease; the mean eczema-related sleep numerical rating scale (NRS) was 5.6 (SD 2.9) and mean worst daily pruritus NRS was 6.2 (SD 2.7). Patients also reported a substantial impact on quality of life, demonstrated by a mean Dermatology Life Quality Index of 15.6 (SD 6.9). Overall, 79 patients were biologic-naïve and 19 were biologic-experienced (data missing; n=2). All biologic-experienced patients were previously treated with dupilumab, of whom most experienced one or more treatment failures. Reasons for switching from dupilumab included lack or loss of effectiveness, and adverse events, which most commonly included conjunctivitis. Conclusions: Initial findings showed that most adult patients with moderate-to-severe AD who were treated with tralokinumab were biologic-naïve, indicating tralokinumab is prescribed as firstline systemic treatment in real-world clinical practice, in line with European Dermatology Forum guidelines. The main reasons for switching from dupilumab were lack or loss of effectiveness, and adverse events, such as conjunctivitis, indicating the need for alternative biologic treatments such as tralokinumab.

Baseline characteristics, disease severity and treatment history of patients with atopic dermatitis included in the German AD registry TREATgermany. Https://doi.org/10.1093/bjd/ljac070 Dear Editor, TREATgermany (www.treatgermany.org) is an investigator-initiated prospective disease registry of daily routine care in patients with atopic dermatitis (AD), aged 18 years and older, who consult a dermatology department or a dermatology practice in Germany. Only patients who reported data on itch severity were included; three patients who received tacrolimus and eight patients who received pimecrolimus had to be excluded owing to missing values.

Skin transcriptome studies in atopic dermatitis (AD) showed broad dysregulation as well as "improvement" under therapy. These observations were mainly made in trials and based on microarray data. Our aim was to explore the skin transcriptome and the impact of systemic treatment in patients of the TREATgermany registry. Biopsy specimens from 59 patients with moderate-to-severe AD before and 30 patients 12 weeks after start of systemic treatment (dupilumab [n = 22] or cyclosporine [n = 8]) and from 31 healthy controls were subjected to mRNA sequencing. Differential expression, pathway enrichment, correlation, and coexpression network analysis were conducted. Both lesional and nonlesional skin showed a stable "core" signature characterized by disturbed epidermal differentiation and activation of IL-31/IL-1 signaling. A second dynamic signature showed progressive enrichment for type 2 inflammation, T H 17 signaling, and natural killer cell function. Markers correlated with disease activity have functions in epidermal barrier properties and immune modulation. IL4RA was among the top 3 central dysregulated genes. Cyclosporine led to a more pronounced global transcriptome reversion and normalized T H 17 cell/IL23 signaling, whereas dupilumab led to a stronger increase in level of epidermal differentiation markers. Both treatments strongly decreased levels of type 2 markers, but overall the residual profile was still profoundly different from that of healthy skin. Lower levels of IL4RA and IL13 and high IL36A expression were related to a stronger clinical response to dupilumab. The AD core signature is characterized by dysregulation of genes related to keratinocyte differentiation and itch signaling. A dynamic signature reflects progressive immune responses dominated by type 2 cytokines with an additional role of T H 17 and natural killer cell signaling. [ABSTRACT FROM AUTHOR]

Tralokinumab is a high-affinity, fully human IgG4 monoclonal antibody that specifically inhibits interleukin-13 (IL-13), a key driver of atopic dermatitis (AD) disease progression. Clinical trials have shown that tralokinumab is efficacious in patients with moderate-to-severe AD and has a favorable safety profile, including a low frequency of adverse events (AEs) such as conjunctivitis. However, management of patients in routine clinical practice differ from those enrolled in clinical trials due to strict inclusion/exclusion criteria, and there is currently a lack of clinical data on tralokinumab use in the real-world setting. TRACE is an observational cohort study of patients with AD, which aims to better understand the effectiveness, safety and clinical use of tralokinumab in the real-world setting. This study aims to describe baseline characteristics and initial insights from the first 100 patients enrolled into TRACE in Germany. TRACE is a longitudinal, prospective, new user, noncomparative, observational, single-cohort study, with primary data collection of adult patients with AD who are treated with tralokinumab, according to national approved labels. The study is taking place across countries in Europe, North America and the Middle East. The primary objective is to assess changes in clinical signs and symptoms of AD in tralokinumab-treated patients. Secondary objectives are to investigate safety, quality of life, patient-reported outcomes and adherence, among others. This analysis includes the first 100 patients enrolled from 39 sites across Germany. Of the first 100 patients in TRACE initiated on tralokinumab in Germany, the majority were males. Most patients had moderate-to-severe disease as indicated by their mean Investigator's Global Assessment score and mean Eczema Area and Severity Index. Patients reported heavy symptomatic burden of disease, as demonstrated by their mean eczema-related sleep numerical rating scale (NRS) and mean worst daily pruritus NRS. Patients also reported a substantial impact on quality of life, as demonstrated by mean Dermatology Life Quality Index. Overall, approximately 4/5 of the patients were biologic-naïve. All biologic-experienced patients were previously treated with dupilumab, of whom most experienced one or more treatment failures. Reasons for switching from dupilumab included lack or loss of efficacy, and AEs, which included mainly conjunctivitis. Initial findings from the first 100 patients from TRACE in Germany showed that the majority of adult patients with moderate-to-severe AD treated with tralokinumab were biologic-naïve, indicating that tralokinumab is prescribed as first-line systemic treatment in the real world, in line with European Dermatology Forum guidelines. Of patients who switched from dupilumab, the main reasons for switching were lack or loss of efficacy, and conjunctivitis, indicating the need for an alternative biologic treatment such as tralokinumab.

Background The goal of clinical registries is to document the use and effectiveness of therapeutic interventions under real-life conditions. They are an indispensable prerequisite of evidence-based health care. Methods Initiated in 2011, the German Atopic Dermatitis Registry TREATgermany is the first registry of patients with severe atopic dermatitis worldwide. Adults with severe atopic dermatitis (current/prior systemic antiinflammatory treatment and/or objective SCORAD ≥ 40) are prospectively followed over the course of 24 months. Employed treatment modalities are documented, and validated measuring tools are used to assess clinical disease severity (EASI, objective SCORAD), quality of life (DLQI), symptoms (POEM), global disease severity, as well as patient satisfaction. Herein, we describe the characteristics, therapeutic selection, and effectiveness of systemic antiinflammatory treatments of patients enrolled in the registry until October 2014. Results Overall, 78 individuals (mean age 39 years, 61 % men) were enrolled at five recruitment centers. Patients frequently made use of inpatient and outpatient services. Not only was cyclosporine the most frequently administered systemic treatment, but also the most effective (EASI 50 response rate 51 %; EASI 75 response rate 34 % at 12 weeks). Azathioprine, methotrexate, oral prednisolone, mycophenolate, alitretinoin, and leflunomide were also used in some patients. Conclusions The present analysis of the German Atopic Dermatitis Registry provides important data with respect to current medical care of adults with severe atopic dermatitis in Germany. It shows the high disease burden, the benefits of current treatment options, and the need for additional effective and safe long-term treatment options. [ABSTRACT FROM AUTHOR]

Altered quantities, activity, and composition of natural killer (NK) cells in blood as well as expression changes of genes involved in NK-cell function in skin lesions of patients with atopic dermatitis (AD) were recently reported. We sought to comprehensively analyze cutaneous NK-cell transcriptomic signatures in AD, and to examine changes under treatment. We analyzed NK-cell signatures in skin transcriptome data from 57 patients with moderate to severe AD and 31 healthy controls. In addition, changes after 12 weeks of systemic treatment (dupilumab n = 21, cyclosporine n = 8) were analyzed. Deconvolution of leucocyte fractions was conducted. Immunofluorescence staining of NK cells was performed on paraffin-embedded skin sections. Immunofluorescence staining revealed a relatively high abundance of both NK cells and CD3+CD56+ cells in lesional as compared with nonlesional and healthy skin. Lesional and to a lesser extent nonlesional skin showed a strong upregulation of NK-cell markers together with a dysbalanced expression of inhibitory and activating receptors, which was not reverted under treatment. Digital cytometry showed a decrease in activated and an increase in resting NK cells in both lesional and nonlesional skin, which was reverted by both treatment with dupilumab and cyclosporine. The NK-cell transcriptomic signature remained upregulated after treatment, but there was a shift on the qualitative level, indicating a compositional change in NK-cell subsets toward CD56bright NK cells. Lesional AD skin shows a NK-cell dysregulation, which despite clinical improvement under systemic therapy was only partially reverted, and which may represent a yet underappreciated disease mechanism.
