RESUMEN
BACKGROUND: Phototherapy is used to treat atopic dermatitis (AD). Evidence for its efficacy, impact on quality of life, cost-effectiveness and short- and long-term safety with real-life usage is weak. OBJECTIVES: We established a taskforce to examine how phototherapy is currently being used as a treatment for AD across the United Kingdom and Europe to inform our understanding and guide future research into management of patients with AD using UV-based phototherapies. METHODS: An anonymous electronic multiple-response survey exploring phototherapy prescribing practices and experience of phototherapy modalities was developed by the study authors and sent to members of phototherapy networks from the United Kingdom and Europe. Responses were received between February and July 2021. RESULTS: About 144 respondents from 27 European countries completed the survey. NBUVB was the most widely used [n = 138 (96%)]. Home-based NBUVB was available in 8/27 countries (25/144 respondents, 17%). Oral psoralen-UVA (PUVA) was more widely available than bath PUVA (n = 106, 74% vs. n = 60, 42%) and used mainly in adult patients. 49/144 (34%) of respondents had access to UVA1. Phototherapy would be considered instead of systemic treatment in 96% of adults and 82% of children for NBUVB, versus 40% of adults and 3% of children for PUVA. Starting doses, standard dosing increments, length of treatment courses, lifetime limits for treatments and thresholds for performing annual skin assessments varied between responders. CONCLUSIONS: NBUVB was the most widely used phototherapy for AD in adult and paediatric patients, while PUVA and UVA1 were less used. Prescribing practices varied considerably, highlighting the lack of consensus practice in many different aspects of phototherapy for the treatment of AD in children and adults. This indicates that further studies are required to determine optimal phototherapeutic regimens for AD and informs our understanding of parameters that should be included in future high-quality randomized controlled trials (RCT) of phototherapy.

The nipple is the focal point of the human breast and serves important physiological, sexual, and aesthetic purposes. It can be affected by atopic, irritant, and allergic contact eczema, which often reduce the patient's quality of life. The objective of this article is to discuss the different types of nipple eczema and highlight relevant differential diagnoses and treatment options. A systematic search of PubMed was conducted to identify and critically appraise the existing literature on the topic. All articles on nipple eczema were considered eligible, regardless of publication date, language or study design. A final of 33 manuscripts on nipple eczema remained. The scarce literature and the limited number of high-quality manuscripts impedes provision of structured data on nipple eczema. To securely reach the educative value of this manuscript, the systematic review was combined with a manual databank search and selected manual search of textbooks. The differential diagnosis of nipple eczema encompasses among others nipple psoriasis, nipple candidiasis and Paget's disease. In case of diagnostic uncertainty, swabs or biopsies are indicated. Treatment of nipple eczema needs to rapidly control the signs and symptoms of the disease, since it can have a negative effect on quality of life and can lead to premature arrest of breastfeeding. The key treatment step is starting with topical corticosteroids or calcineurin inhibitors, both of which are considered safe during lactation. Avoidance of provoking factors, such as repetitive friction, chemical agents, or allergens, can help. The use of nipple protection devices can be proposed for nursing women and sometimes adjusting of latch/suck positioning during breastfeeding is needed. Furthermore, patients should be advised to moisturize the nipple intensively and to switch to emollient wash products. Warm water compresses, black tea compresses or commercially available tannin containing topicals can provide comfort.

Neural progenitor cells (NPC) represent potential cell transplantation therapies for CNS injuries. To understand how lesion environments influence transplanted NPC fate in vivo, we derived NPC expressing a ribosomal protein-hemagglutinin tag (RiboTag) for transcriptional profiling of transplanted NPC. Here, we show that NPC grafted into uninjured mouse CNS generate cells that are transcriptionally similar to healthy astrocytes and oligodendrocyte lineages. In striking contrast, NPC transplanted into subacute CNS lesions after stroke or spinal cord injury in mice generate cells that share transcriptional, morphological and functional features with newly proliferated host astroglia that restrict inflammation and fibrosis and isolate lesions from adjacent viable neural tissue. Our findings reveal overlapping differentiation potentials of grafted NPC and proliferating host astrocytes; and show that in the absence of other interventions, non-cell autonomous cues in subacute CNS lesions direct the differentiation of grafted NPC towards a naturally occurring wound repair astroglial phenotype.

Atopic dermatitis (AD) is a chronic, heterogenous, inflammatory skin disorder associated with a high skin-related health burden, typically starting in childhood and often persisting into adulthood. AD is characterized by a wide range of clinical phenotypes, reflecting multiple underlying pathophysiological mechanisms and interactions between genetics, immune system dysregulation and environmental factors. In this review, we describe the diverse cellular and molecular mechanisms involved in AD, including the critical role of T-cell-driven inflammation, primarily via T helper (Th) 2- and Th17-derived cytokines, many of which are mediated by the Janus kinase (JAK) signaling pathway. These local inflammatory processes interact with sensory neuronal pathways, contributing to the clinical manifestations of AD, including itch, pain and sleep disturbance. The recent elucidation of the molecular pathways involved in AD has allowed treatment strategies to evolve from broad-acting systemic immunosuppressive therapies to more targeted agents, including JAK inhibitors and cytokine-specific biologic agents. Evidence from the clinical development of these targeted therapies has reinforced and expanded our understanding of the pathophysiological mechanisms underlying AD and holds promise for individualized treatment strategies tailored to specific AD subtypes.

BACKGROUND: Atopic dermatitis (AD) is associated with an increased risk for viral infections including those caused by herpes simplex virus and varicella zoster virus. OBJECTIVES: This study examined treatment-emergent (TE) herpes simplex infection including eczema herpeticum (EH), and herpes zoster (HZ), in adult patients with AD receiving ≥1 dose of baricitinib (BARI), an oral selective inhibitor of Janus kinase 1/2. METHODS: We evaluated data from six double-blinded, randomized, placebo-controlled (PC) trials and two long-term extension studies, within three analysis sets: PC, 2-4-mg BARI extended and All-BARI-AD. Frequency, incidence rate (IR)/100 person-years (PYs) and clinical characteristics of TE-herpes simplex, EH and HZ were reported. RESULTS: In the All-BARI-AD dataset (n = 2531; 2247 PYs), herpes simplex was reported in 8.9% of patients (n = 224; IR = 10.3). Most herpes simplex events were rated as mild or moderate (93.3%), rarely led to permanent discontinuation (2.2%) and presented mostly as oral/perioral herpes simplex (51.3%). TE-EH occurred at a low frequency (All-BARI-AD 1.7% n = 43; IR = 2.0) and were reported in 0.5%, 0.2% and 1.4% of patients receiving placebo, 2-mg or 4-mg BARI respectively. In the All-BARI-AD dataset, most events were investigator-rated as mild/moderate (79.1%), affected ≤2% of the body surface area (74.2%) and occurred as single events (88.4%). Serious TE-EH (n = 11) occurred exclusively in patients with poor disease control (vIGA-AD™ score ≥3) at infection onset. TE-HZ was reported in 2.1% of BARI patients (n = 53; IR = 2.3), without a dose relationship during the PC period (IR = 2.7 and IR = 0.0) or the extended dataset (IR = 3.7 and IR = 1.7) for 2- or 4-mg BARI respectively. CONCLUSIONS: TE-herpes simplex was common, while occurrence of EH was uncommon. Most events of EH were localized with involvement of a small BSA and were linked to poor disease control. Events of HZ were rare in the PC dataset and without a dose dependent increase in frequency.

BACKGROUND AND OBJECTIVES: The economic burden of atopic dermatitis (AD) is of particular interest. The present study aims to analyse the association of disease-related characteristics, annual costs and treatment benefits in AD. METHODS: Between August 2017 and June 2019, a cross-sectional observational study in patients with AD was conducted in Germany. Cost-of-illness data were assessed from the societal perspective. Disease characteristics included severity, time since diagnosis and therapy, as well as atopic comorbidity and the implementation of prevention measures. Subgroup analyses of the total costs were conducted for these characteristics. A linear regression model was applied to analyse the impact of disease characteristics on the costs. Furthermore, associations of biologic treatment with outcome parameters were analysed. RESULTS: A total of 1291 patients from 111 centres were included in the analyses. The total costs amounted on average to 3660 ± 6428 per patient and year. Higher costs were shown in various patient groups, for example, in patients using biologics ( 20 983 vs. 2470). In a regression analysis, gender, education and the number of implemented prevention measures were identified as significant predictors of costs. Patients treated with biologics showed consistently better outcome parameters and were more often satisfied with their treatment. CONCLUSIONS: Gender, education and implemented prevention measures are significant cost determinants in AD. The results confirm that treatment with biologics is the main cost driver in AD. However, incremental patient-relevant benefits of high-priced therapy are reflected by the significantly better clinical outcomes in the group treated with biologics.

Sensitive skin is clinically defined by characteristic sensory perceptions including tightness, abnormal stinging, burning, tingling, pain and pruritus. Facial erythema may occur, and other body areas can be involved. Sensitive skin affects extremely the quality of life. According with the International Forum for the Study of Itch (IFSI), sensitive skin is defined as a syndrome. The unpleasant sensations described are in response to stimuli that normally should not provoke such sensations. Moreover, these unpleasant sensations cannot be explained by any skin disease. Sensitive skin is always considered when any new consumer health, cosmetic or household product is introduced in the market. Once sensitive skin is recognized, it is mandatory to identify specific triggers that commonly induce symptoms and even cutaneous visible signs. Sensitive skin syndrome can be exacerbated by an allergic setting and environmental factors (cold, hot, dryness, pollution, wind, chemicals ...), a source of intolerance and unpleasant sensations. Cosmetics are the main triggering factors of sensitive skin according to patient's reports. The presence of potentially irritant substances in their composition increases the clinical expression of symptoms. As sensitive skin is frequent, and it is increasing based on the current development of cosmetic use worldwide, there is a need to develop better skin care products. The continuous research of active and safe skin care products to prevent and treat sensitive skin is extremely welcome.

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: Tralokinumab, a fully human IgG4 monoclonal antibody that specifically binds with high affinity to interleukin-13, effectively reduces moderate-to-severe atopic dermatitis (AD) when given every 2 weeks. The incidence of conjunctivitis is elevated vs. placebo, but severity and aetiology have not been examined. OBJECTIVE: To analyse conjunctivitis data recorded in five randomized, placebo-controlled trials of tralokinumab in adult patients with moderate-to-severe AD. METHODS: Overall, 2285 adults with AD were studied up to 16 weeks. Cochran-Mantel-Haenszel weights were applied to calculate the adjusted incidence of adverse events. RESULTS: The incidence of conjunctivitis was higher (7·5%) with tralokinumab than with placebo (3·2%). Most events were mild or moderate in severity, and 78·6% and 73·9% of events resolved during the trial in the tralokinumab and placebo groups, respectively. Two (1·4%) events led to the permanent discontinuation of tralokinumab. An increased incidence of conjunctivitis, regardless of treatment group, was associated with more severe baseline AD, and history of allergic conjunctivitis/atopic keratoconjunctivitis, as well as the number of atopic comorbidities. LIMITATIONS: This analysis reports events up to week 16 only, with limited confirmation of conjunctivitis and its aetiology by an ophthalmologist, and insufficient reporting of ophthalmic treatments. CONCLUSIONS: Treatment with tralokinumab was associated with an increased incidence of conjunctivitis vs. placebo, but these cases were mostly mild and transient.

BACKGROUND: Sleep disturbance (SD) is an important part of the burden of atopic dermatitis (AD), but patient-reported outcomes that are easy to understand and interpret in the target population have been lacking. A daily, single-item, self-reported SD 11-point numerical rating scale (NRS) was recently developed to assess SD for patients with moderate-to-severe AD, but its psychometric properties have not yet been described. OBJECTIVES: To assess the psychometric properties of the SD NRS in patients with moderate-to-severe AD. METHODS: The psychometric properties of the SD NRS were assessed using data from a phase IIb clinical trial in 218 adults with moderate-to-severe AD. RESULTS: Test-retest reliability of the SD NRS was substantial to almost perfect (interclass correlation 0·66-1·00) in participants who had stable SD or stable pruritus scores over 1 week. Baseline correlations were moderate to large (r > 0·30) between SD NRS and pruritus or sleep loss scores, but were small (r = -0·11 to 0·17) between SD NRS and EQ-5D-3L index and visual analogue scores, Hospital Anxiety and Depression Scale, Scoring Atopic Dermatitis, and Investigator's Global Assessment. The SD NRS could discriminate groups of participants in the expected direction according to different quality-of-life scores but not according to different clinician-reported disease severity scores. SD NRS scores significantly decreased as sleep loss, itch and quality-of-life scores improved. Analysis of meaningful change suggested a 2-5-point improvement as the initial range of responder definition in the SD NRS score. CONCLUSIONS: The SD NRS is a reliable, valid and responsive measure of SD in adults with moderate-to-severe AD.

BACKGROUND: Dupilumab, a first-in-class therapy targeting the two key cytokines involved in the persistent underlying inflammatory pathway in atopic dermatitis (AD), is approved for treatment of moderate-to-severe AD in Europe, USA, Japan and several other countries. OBJECTIVE: To assess dupilumab effects on SCORing Atopic Dermatitis (SCORAD) and component scores (objective and subjective SCORAD) over time in adults with moderate-to-severe AD. METHODS: This post hoc analysis included 2,444 patients in four placebo-controlled, double-blind, randomized, phase 3 trials. SOLO 1 and 2 (NCT02277743; NCT02277769) evaluated 16 weeks of dupilumab monotherapy against placebo. CAFÉ (NCT02755649) and CHRONOS (NCT02260986) evaluated dupilumab with concomitant topical corticosteroids (TCS) against TCS alone for 16 and 52 weeks, respectively. RESULTS: 2,444 patients randomized to treatment in SOLO 1 and 2 (N = 1,379), CAFÉ (N = 325) and CHRONOS (N = 740) were analyzed. Dupilumab treatment significantly improved overall SCORAD and individual components as early as Week 1 or 2, with significant and clinically meaningful differences vs. control through end of treatment (p < .0001). These results occurred irrespective of dupilumab regimen, 300 mg subcutaneously weekly or every 2 weeks. CONCLUSIONS: In four large phase 3 trials in adults with moderate-to-severe AD, dupilumab treatment with or without concomitant TCS resulted in rapid and sustained improvements in all SCORAD outcomes vs. placebo or TCS alone.

BACKGROUND: Itch, skin pain, and sleep disturbance are burdensome symptoms in atopic dermatitis (AD) that negatively influence a patient's quality of life (QoL). OBJECTIVE: To evaluate the impact of baricitinib on patient-reported outcomes (PROs) in adult patients with moderate-to-severe AD, and explore the association between improvement in key signs and symptoms of AD with improvements in QoL and patient's assessment of disease severity. METHODS: Data were analyzed from two phase III monotherapy trials (BREEZE-AD1/BREEZE-AD2) in which patients were randomized 2:1:1:1 to once-daily placebo, baricitinib 1-mg, 2-mg, or 4-mg for 16 weeks and assessed using PRO measures. RESULTS: At week 16, baricitinib 4-mg and 2-mg significantly reduced itch severity (Itch Numeric Rating Scale (NRS) (BREEZE-AD1: percent change from baseline -36.6% and -29.4% vs. placebo (-12.0%), p≤.001 and p≤.05; BREEZE-AD2: -47.2% and -46.9% vs. placebo (-16.6%), p≤.001). Baricitinib significantly reduced SCORing AD (SCORAD) pruritus (4-mg in BREEZE-AD1 and 2-mg in BREEZE-AD2) and Patient Oriented Eczema Measure (POEM) itch (both doses). Improvements in skin pain severity and sleep disturbance were also observed. Improvements in AD symptoms showed higher correlations with patients' assessment of AD severity and QoL than improvements in skin inflammation. CONCLUSIONS: Baricitinib significantly improved symptoms in patients with moderate-to-severe AD. CLINICALTRIALS.GOV IDENTIFIERS: NCT03334396 (BREEZE-AD1) and NCT03334422 (BREEZE-AD2).
