ABSTRACT
Background: Patients with atopic dermatitis (AD) exhibit heterogeneous clinical phenotypes, reflecting different combinations of itch and lesional severity. AD with severe itch but clear-moderate lesions, also known as itch-dominant AD, is a common clinical phenotype. Objectives: To evaluate abrocitinib efficacy in patients with moderate-to-severe AD who have itch-dominant AD. Methods: This post hoc analysis includes pooled data from clinical trials of patients with moderate-to-severe AD receiving abrocitinib (100 or 200 mg) as monotherapy (phase 2b; phase 3 JADE MONO-1 and JADE MONO-2) or in combination with topical therapy (phase 3 JADE COMPARE). Data from the ongoing long-term JADE EXTEND trial (data cutoff April 2020) were also evaluated. Itch-dominant AD was defined as baseline Peak Pruritus Numerical Rating Scale (PP-NRS) score of 7-10 and Investigator's Global Assessment of 0-3 or Eczema Area and Severity Index of 0â21. Assessments included a ≥4-point improvement in PP-NRS (PP-NRS4), PP-NRS score of 0 (no itch) or 1 (little itch) in patients with PP-NRS score ≥2 at baseline, ≥4-point improvement from baseline in Patient-Oriented Eczema Measure (POEM-4), Patient Global Assessment (PtGA) of clear or almost clear, and Dermatology Life Quality Index (DLQI) score of 0 or 1 (no impact or little impact of AD on quality of life [QoL]). Results: In the pooled monotherapy trials, 37% of patients had itch-dominant AD at baseline. As early as Week 2, more patients with itch-dominant AD achieved PP-NRS4 with abrocitinib 100 mg (35%) and abrocitinib 200 mg (57%) versus placebo (7%); 6% and 22% versus 0%, respectively, achieved PP-NRS 0/1. More patients achieved a PtGA of clear/almost clear at Week 12 with abrocitinib 100 mg (28%) and abrocitinib 200 mg (45%) than placebo (9%). Additionally, abrocitinib led to clinically meaningful improvements in POEM and DLQI. Most patients with itch-dominant AD experienced itch improvement over time with abrocitinib monotherapy or with concomitant topical therapy; 86%-87% and 62%-67% of patients had no itch-moderate itch and clear-moderate lesions by weeks 24 and 48, respectively. Conclusions: Abrocitinib is highly efficacious in patients with itch-dominant AD, demonstrating rapid, deep, and sustained improvements in itch and clinically meaningful improvements in patients' QoL. Trial Registration Numbers: NCT02780167; NCT03349060; NCT03575871; NCT03720470; NCT03422822.
ABSTRACT
Allergic contact dermatitis is characterized by its appearance of red, raised and infiltrated, scaling or scabbed skin and intense pruritus, and distinguished from irritant contact dermatitis by its specific immune process and histopathology. Many contact allergens are low molecular weight chemicals including metals such as nickel, cobalt, and chromium, preservatives, and adhesives. When such materials are used internally in biomedical devices, they are similarly capable of causing sensitization and an inflammatory response. Sometimes the reaction remains internal, and presents as swelling, pain, stiffness, decreased range of motion, and internal itching around the implant. Such reactions may, in some cases, also extend to include a localized or, rarely, systemic contact dermatitis indicative of the same process. This review will present an overview of reported skin and local internal reactions to orthopedic implants, which are the largest category of implanted internal metal devices. Immune reactions to smaller categories of medical appliances include cardiac devices and vascular stents, neuromodulation devices, diabetic appliances, Nuss bar surgery for pectus excavatum, and dental and spinal implants. We will review the available diagnostic tools, the consensus on interpretation, and reported strategies for treatment.
ABSTRACT
BACKGROUND: It is unknown whether the pre-biologic treatment journey affects subsequent biologic drug survival. OBJECTIVE: To examine the potential impact of a complex treatment journey on subsequent biologic drug survival in patients with psoriasis. METHODS: The study utilized longitudinal data from Danish national registries and included all patients who, for the first time, initiated a biological treatment for psoriasis. Maximum follow-up was 5 years and patients were included from 1 January 2010 to 30 June 2021. The study used three definitions of exposure to a complex treatment journey and the following conventional systemic treatments: acitretin, cyclosporine, dimethyl fumarate and methotrexate. The first definition was the cumulative number of treatment series. The second definition comprised the number of unique treatments. The third definition was time from the first conventional systemic treatment to biological therapy. Drug survival for the three definitions were illustrated using Kaplan-Meier curves and compared using log-rank test. The sensitivity analysis largely confirmed these findings by grouping patients according to pharmacotherapy. RESULTS: A total of 2496 patients were included in the study, with 1380 (55.3%) receiving adalimumab, 608 (24.4%) receiving ustekinumab, 271 (10.9%) receiving secukinumab, 166 (6.7%) receiving etanercept and 71 (2.8%) receiving infliximab. The mean age at initiation of biologics was 43.6 years (standard deviation (SD) 15.2 years), and most patients were male (62.9%). During the follow-up of 5477 patient years, 1953 patients (78.2%) reached the main endpoint of discontinuation. Using a log-rank test, the probability of remaining on treatment was unaffected by the three definitions of complexity of the treatment journey. CONCLUSION: None of the three exposures used to assess the complexity of the pre-biologic treatment journey appeared to impact drug survival. As long as patients experience adequate disease control, these results suggest that conventional systemic treatment do not negatively impact the drug survival of subsequent biologics.
ABSTRACT
BACKGROUND: Atopic dermatitis (AD) is mainly driven by type 2 inflammation and often treated with topical agents. Studies comparing differences in biomarkers between these treatments are lacking. OBJECTIVES: The aim of this study was to evaluate the effects of topical betamethasone 17-valerate 0.1% and tacrolimus 0.1% ointment on skin barrier function and inflammatory biomarkers in skin and blood in adults with AD. METHODS: In this randomized parallel-group double-blind double-dummy active-comparator study design, 36 adults with AD were treated with either whole-body topical corticosteroid (betamethasone ointment 0.1% plus placebo once daily, n = 18) or calcineurin inhibitor (tacrolimus ointment 0.1% twice daily, n = 18). At baseline, after 2 weeks of daily treatment and after further 4 weeks of twice-weekly maintenance treatment, we evaluated AD severity, levels of natural moisturizing factor (NMF) and cytokines in the skin and blood and characterized circulating T cells. RESULTS: Mean AD severity at baseline corresponded to moderate disease and decreased significantly in both groups. Levels of NMF increased significantly in the tacrolimus group after 2 weeks of treatment (p = 0.002) and tended to increase more than betamethasone at week 6 (p = 0.06). Most skin cytokines decreased with both treatments. However, IL-8, IL-18, IL-22, IP-10, MDC, MMP-9 and TARC were significantly more decreased with betamethasone than tacrolimus after 2 weeks, while after 6 weeks this was only the case for IL-8 and MMP-9. Approximate half of the systemic cytokines decreased significantly with both treatments, but betamethasone decreased MDC significantly more after 2 weeks of treatment. T-cell characterization analyses indicated slight differences in the expression and activation of T cells between groups. CONCLUSION: Topical treatment of AD with betamethasone and tacrolimus ointment effectively reduced disease severity, cutaneous and systemic inflammatory markers. Betamethasone was more effective in decreasing inflammation, but tacrolimus improved skin hydration (NMF levels) more than betamethasone.
ABSTRACT
Skin barrier function (SBF) disorders are a class of pathologies that affect a significant portion of the world population. These disorders cause skin lesions with intense itch, impacting patients' physical and psychological well-being as well as their social functioning. It is in the interest of patients that their disorder be monitored closely while under treatment to evaluate the effectiveness of the ongoing therapy and any potential adverse reactions. Symptom-based assessment techniques are widely used by clinicians; however, they carry some limitations. Techniques to assess skin barrier impairment are critical for understanding the nature of the disease and for helping personalize treatment. This review recalls the anatomy of the skin barrier and describes an atomic-force microscopy approach to quantitatively monitor its disorders and their response to treatment. We review a panel of studies that show that this technique is highly relevant for SBF disorder research, and we aim to motivate its adoption into clinical settings.
ABSTRACT
Atopic diseases such as atopic dermatitis, food allergy, allergic rhinoconjunctivitis, and/or asthma are common. In Denmark, however, there are multiple referral pathways for these diseases in the healthcare system and they are poorly understood. To describe how children with atopic diseases navigate their way through the Danish healthcare system, a questionnaire was distributed to children aged ≤ 17 years, who were being treated for atopic diseases between August 2020 and June 2021, either by a practising specialist or a hospital department, in the Capital Region of Denmark. A total of 279 children completed the questionnaire and most were referred to a specialist or to a hospital by their general practitioner. No "common track" to hospital existed for patients with ≥ 3 atopic diseases. These patients were more often referred to a hospital compared with children with 2 atopic diseases or fewer (odds ratio [OR] 3.79; 95% CI 2.07-7.24). The primary determinants for hospital treatment were food allergy (OR 4.69; 95% CI 2.07-10.61) and asthma (OR 2.58; 95% CI 1.18-5.63). In conclusion, children with multiple atopic diseases were more likely to be referred to hospital departments than to practising specialists, mainly due to food allergies.

BACKGROUND: Understanding the role of calcitonin gene-related peptide (CGRP) in the pathogenesis of rosacea might provide new therapeutic avenues for individuals with this disease. OBJECTIVE: To compare plasma levels of CGRP between individuals with rosacea and healthy controls. METHODS: In this cross-sectional case-control study conducted in Copenhagen, Denmark, we collected blood samples from the antecubital vein from adults with rosacea and from healthy controls. RESULTS: We enrolled 123 individuals with rosacea and 68 healthy controls. After adjusting for age and sex, plasma levels of CGRP were significantly higher in individuals with rosacea (mean, 95% confidence interval: 140.21 pmol/L, 128.50-151.92 pmol/L), compared with controls (110.77 pmol/L, 99.91-120.14 pmol/L, p = 0.002). Plasma levels of CGRP were not affected by age, sex, BMI, concomitant migraine, rosacea sub- or phenotype, concomitant disease or current treatment. LIMITATIONS: Participants were not age-, sex- and BMI-matched. CONCLUSIONS AND RELEVANCE: Elevated plasma levels of CGRP in individuals with rosacea suggest a role of CGRP in the pathogenesis of rosacea. Targeting CGRP signalling might hold therapeutic promise in people affected by this disease. GOV LISTING: NCT03872050.
ABSTRACT
Background: Biomarkers associated with disease severity and comorbid metabolic syndrome (MetS) in patients with hidradenitis suppurativa (HS) are lacking. Objective: To identify biomarkers associated with disease severity and comorbid MetS in patients with HS. Methods: Data on hospital outpatients with HS were obtained through clinical examination and interviews. Indicators of systemic inflammation; C-reactive protein (CRP), erythrocyte sedimentation-rate (ESR), neutrophil/lymphocyte-ratio (NLR), platelet/lymphocyte-ratio (PLR), monocyte/lymphocyte-ratio (MLR), platelet/neutrophil-ratio (PNR), pan-immune-inflammation-value (PIV), and systemic-immune-inflammatory-index (SII), were calculated from blood samples. Results: Seven hundred patients were included; of those 444 (63.4%) and 256 (36.6%) were female and male, respectively, with a median age of 38.3 years (IQR = 27.9-51.0). Increasing CRP, ESR, NLR, PIV, and SII (P < .001) were significantly associated with increasing Hurley-stage and international hidradenitis suppurativa severity score system 4 (IHS4)-score in adjusted analysis. A doubling in CRP (OR 1.59 (1.36-1.85), P < .001), ESR (OR 1.39 (1.17-1.66), P < .001) and PIV (OR 1.41 (1.12-1.77) P = .002) was associated with MetS in adjusted analysis. ESR was the best estimator for severe IHS4-score (AUC = 0.72 (0.66-0.77), P < .001) and Hurley III (AUC = 0.79 (0.73-0.85), P < .001) whereas CRP was best for MetS (AUC = 0.67 (0.62-0.72), P < .001). Limitations: Patients in a hospital setting tend to have more severe disease. Conclusion: Biomarkers like CRP, ESR, and PIV measuring systemic inflammation were associated with disease severity and comorbid MetS in patients with HS.
ABSTRACT
The World Allergy Organization recommends probiotics in the prevention of atopic dermatitis in high-risk populations. Mutations in the filaggrin gene (FLG) result in an increased risk of atopic dermatitis through disruption of the skin keratin layer. This exploratory study investigated whether the preventive effect of maternal probiotics was evident in children with and without FLG mutations. DNA was collected from children (n = 228) from the Probiotic in the Prevention of Allergy among Children in Trondheim (ProPACT) study. Samples were analysed for 3 common FLG mutations (R501X, R2447X, and 2282del4). Overall, 7% of children had heterozygous FLG mutations; each child had only one of the 3 mutations. Mutation status had no association with atopic dermatitis (RR = 1.1; 95% CI 0.5 to 2.3). The risk ratio (RR) for having atopic dermatitis following maternal probiotics was 0.6 (95% CI 0.4 to 0.9) and RR was similar if the child expressed an FLG mutation (RR = 0.6; 95% CI 0.1 to 4.1) or wildtype FLG (RR = 0.6; 95% CI 0.4 to 0.9). The preventive effect of probiotics for atopic dermatitis was also evident in children without FLG mutation. Larger confirmatory studies are needed.

BACKGROUND: Nickel is the leading cause of contact allergy in Europe, with 14.5% of the adult population being sensitized. Despite regulations limiting nickel release from consumer items, the incidence and prevalence of nickel allergy remain high. OBJECTIVE: To investigate the clinical and subclinical immune response to low-dose nickel exposure on nickel pre-exposed skin to assess the adequacy of current regulatory limits. METHOD: Nickel-allergic and healthy controls were patch tested with nickel twice with a 3-4 weeks interval. The first exposure used the diagnostic concentration of 2000 µg/cm2 nickel sulphate, and the same skin areas were then re-exposed to 0.2, 0.5, 12.8 and 370 µg/cm2 nickel sulphate. After 48 h, the patch reactions were examined for clinical signs of eczema, and skin biopsies were collected. The transcriptomic immune profile was analysed with Nanostring nCounter and quantitative polymerase chain reaction. RESULTS: Two nickel-allergic participants (15%) had clinical reactions to the regulatory limiting doses for nickel (0.2/0.5 µg/cm2) following re-exposure. There was immune activation in all skin areas following re-exposure to nickel, predominantly mediated by up-regulation of cytokines and chemokines. In all nickel re-exposed skin areas, 81 genes were up-regulated independent from the clinical response. In skin areas exposed to 0.2 µg/cm2, 101 immune-related genes were differentially expressed, even when no clinical response was observed. Healthy controls showed up-regulation of three genes in response to nickel re-exposures without any clinical reactions. CONCLUSION: Immune activation can be induced in skin with local memory to nickel upon challenge with nickel doses within the regulatory limits. Our findings suggest that the regulatory limits in the European nickel regulation may not provide sufficient protection for consumers against low-dose exposures.

Importance: Treatment of erythema and flushing in rosacea is challenging. Calcitonin gene-related peptide (CGRP) has been associated with the pathogenesis of rosacea, raising the possibility that inhibition of the CGRP pathway might improve certain features of the disease. Objective: To examine the effectiveness, tolerability, and safety of erenumab, an anti-CGRP-receptor monoclonal antibody, for the treatment of rosacea-associated erythema and flushing. Design, Setting, and Participants: This single-center, open-label, single-group, nonrandomized controlled trial was conducted between June 9, 2020, and May 11, 2021. Eligible participants included adults with rosacea with at least 15 days of either moderate to severe erythema and/or moderate to extreme flushing. No concomitant rosacea treatment was allowed throughout the study period. Visits took place at the Danish Headache Center, Copenhagen University Hospital, Rigshospitalet in Copenhagen, Denmark. Participants received 140 mg of erenumab subcutaneously every 4 weeks for 12 weeks. A safety follow-up visit was performed at week 20. Data analysis occurred from January 2023 to January 2024. Intervention: 140 mg of erenumab every 4 weeks for 12 weeks. Main Outcomes and Measures: The primary outcome was mean change in the number of days with moderate to extreme flushing during weeks 9 through 12, compared with the 4-week run-in period (baseline). The mean change in number of days with moderate to severe erythema was a secondary outcome. Adverse events were recorded for participants who received at least 1 dose of erenumab. Differences in means were calculated with a paired t test. Results: A total of 30 participants (mean [SD] age, 38.8 [13.1] years; 23 female [77%]; 7 male [23%]) were included, of whom 27 completed the 12-week study. The mean (SD) number of days with moderate to extreme flushing was reduced by -6.9 days (95% CI, -10.4 to -3.4 days; P < .001) from 23.6 (5.8) days at baseline. The mean (SD) number of days with moderate to severe erythema was reduced by -8.1 days (95% CI, -12.5 to -3.7 days; P < .001) from 15.2 (9.1) days at baseline. Adverse events included transient mild to moderate constipation (10 participants [33%]), transient worsening of flushing (4 participants [13%]), bloating (3 participants [10%]), and upper respiratory tract infections (3 participants [10%]), consistent with previous data. One participant discontinued the study due to a serious adverse event (hospital admission due to gallstones deemed unrelated to the study), and 2 participants withdrew consent due to lack of time. Conclusions and Relevance: These findings suggest that erenumab might be effective in reducing rosacea-associated flushing and chronic erythema (participants generally tolerated the treatment well, which was consistent with previous data), and that CGRP-receptor inhibition holds potential in the treatment of erythema and flushing associated with rosacea. Larger randomized clinical trials are needed to confirm this finding. Trial Registration: ClinicalTrials.gov Identifier: NCT04419259.

Quality of life impairment in dermatology patients and severity of psoriasis are quantified by the Dermatology Life Quality Index (DLQI) and the Psoriasis Area and Severity Index (PASI), respectively. The aim of this study is to compare the correlation between PASI and DLQI in patients from different geographical areas and to identify predictors of high DLQI across geographical regions. Correlations between PASI and DLQI were evaluated using Spearman's rank correlation tests and quantile regression. The study included 1,158 patients with psoriasis, with a median (interquartile range) PASI and DLQI of 6.0 (3.0-12.0) and 8.0 (4.0-15.0), respectively. Correlations were demonstrated between PASI and DLQI, both overall and stratified by geographical region. Quantile (median) regression yielded coefficients of 0.75 (95% confidence interval (95% CI) 0.62, 0.88) for Switzerland, 0.50 (95% CI 0.42, 0.58) for Latin America, 0.34 (95% CI 0.16, 0.51) for Asia, and 0.31 (95% CI 0.08, 0.53) for the USA. Current age, age at diagnosis, sex, body mass index, and psoriasis arthritis affected DLQI in Latin America, while education had an impact among patients treated in Switzerland. Few countries were included within each continent; hence, more data from different countries are necessary for generalizability. The study showed correlations between PASI and DLQI among patients in all included geographical regions. The patients' characteristics affecting DLQI vary worldwide.

BACKGROUND: Skin tape-strips and biopsies are widely used methods for investigating the skin in atopic dermatitis (AD). Biopsies are more commonly used but can cause scarring and pain, whereas tape-strips are noninvasive but sample less tissue. The study evaluated the performance of skin tape-strips and biopsies for studying AD. METHODS: Whole-transcriptome RNA-sequencing was performed on paired tape-strips and biopsies collected from lesional and non-lesional skin from AD patients (n = 7) and non-AD controls (n = 5). RNA yield, mapping efficiency, and differentially expressed genes (DEGs) for the two methods (tape-strip/biopsy) and presence of AD (AD/non-AD) were compared. RESULTS: Tape-strips demonstrated a lower RNA yield (22 vs. 4596 ng) and mapping efficiency to known genes (28% vs. 93%) than biopsies. Gene-expression profiles of paired tape-strips and biopsies demonstrated a medium correlation (R2 = 0.431). Tape-strips and biopsies demonstrated systematic differences in measured expression levels of 6483 genes across both AD and non-AD samples. Tape-strips preferentially detected many itch (CCL3/CCL4/OSM) and immune-response (CXCL8/IL4/IL5/IL22) genes as well as markers of epidermal dendritic cells (CD1a/CD207), while certain cytokines (IL18/IL37), skin-barrier genes (KRT2/FLG2), and dermal fibroblasts markers (COL1A/COL3A) were preferentially detected by biopsies. Tape-strips identified more DEGs between AD and non-AD (3157 DEGs) then biopsies (44 DEGs). Tape-strips also detected higher levels of bacterial mRNA than biopsies. CONCLUSIONS: This study concludes that tape-strips and biopsies each demonstrate respective advantages for measuring gene-expression changes in AD. Thus, the specific skin layers and genes of interest should be considered before selecting either method.

Atopic dermatitis is a chronic, inflammatory skin disease. A variety of systemic treatments are available for patients with moderate-to-severe atopic dermatitis. The efficacy, safety and administration profile of these treatments vary, and determining the optimal treatment strategy may require weighing the benefits and drawbacks of therapies with diverse characteristics. This study used an online discrete choice experiment survey to investigate treatment preferences among adults with atopic dermatitis from Denmark, France, the UK, or Canada. Participants were identified through existing online panels. The survey included questions regarding different treatment attributes, defined based on currently approved treatments for moderate to severe atopic dermatitis. Treatment preferences were measured as the relative importance of different treatment attributes. A total of 713 respondents met the inclusion criteria and completed the survey. The discrete choice experiment identified a significant preference for avoiding the risk of severe adverse events, and for oral pill every day compared with biweekly injections. The time to full effect was not rated as being important. These findings suggest that patients with moderate-to-severe atopic dermatitis prioritize safety as most important, followed by ease of administration in their treatment preferences, while time to full effect and monitoring requirements were the least important attributes.

BACKGROUND: A multitude of factors may influence fatigue in psoriasis and psoriatic arthritis (PsA); however, their individual fatigue components have not been thoroughly examined. OBJECTIVES: To explore characteristics of fatigue and its potential drivers in a cohort of patients with psoriasis with or without PsA. METHODS: Adults with psoriasis and a nonpsoriasis control group completed the Multidimensional Fatigue Inventory-20 questionnaire. Patients with psoriasis also reported joint pain intensity, pruritus, skin pain, and sleep problems using a numerical rating scale. Linear regression models were applied to continuous outcomes, and beta coefficients (ß) for the slopes were estimated with 95% confidence intervals (CIs). RESULTS: Among 2741 adults with psoriasis (of which 593 also had PsA) and 3788 controls, the impact on total fatigue was greatest for PsA (ß = 5.22; 95% CI, 3.55-6.90), followed by psoriasis (ß = 2.10; 95% CI, 0.96-3.25), compared with the general population (Ptrend < .0001). Among patients with psoriasis with or without PsA, increasing joint pain intensity was associated with overall fatigue (ß = 2.23 [95% CI, 2.03-2.44] for each 1-point increase in joint pain numerical rating scale score). LIMITATIONS: We lacked information on the effect of pharmacotherapy. CONCLUSIONS: These findings highlight the importance of a symptom-based approach when treating psoriasis, rather than focusing on objective severity measures alone.
