Defining and Measuring the Scope of Atopic Dermatitis.

Atopic dermatitis (AD) has no definitive diagnostic test and has a large range of phenotypes, making it a difficult disease to assess and define. However, an agreed-upon definition of AD is important for clinical trials, population-based studies, and clinical practice. Several diagnostic criteria systems have been proposed to fill these needs, with none considered the gold standard. To further aid in standardized assessment of AD patients, numerous disease severity and quality-of-life measurement tools have been proposed. There is similarly no gold standard and efforts are ongoing to develop a single consensus scale. Finally, assessment of AD-associated comorbidities, including allergic/immunologic conditions, psychiatric disorders, and metabolic/cardiac conditions, is important when evaluating this patient population.

Allergen immunotherapy for atopic dermatitis: Systematic review and meta-analysis of benefits and harms.

BACKGROUND: Atopic dermatitis (AD, eczema) is driven by a combination of skin barrier defects, immune dysregulation, and extrinsic stimuli such as allergens, irritants, and microbes. The role of environmental allergens (aeroallergens) in triggering AD remains unclear. OBJECTIVE: We systematically synthesized evidence regarding the benefits and harms of allergen immunotherapy (AIT) for AD. METHODS: As part of the 2022 American Academy of Allergy, Asthma & Immunology/American College of Allergy, Asthma and Immunology Joint Task Force on Practice Parameters AD Guideline update, we searched the MEDLINE, EMBASE, CENTRAL, CINAHL, LILACS, Global Resource for Eczema Trials, and Web of Science databases from inception to December 2021 for randomized controlled trials comparing subcutaneous immunotherapy (SCIT), sublingual immunotherapy (SLIT), and/or no AIT (placebo or standard care) for guideline panel-defined patient-important outcomes: AD severity, itch, AD-related quality of life (QoL), flares, and adverse events. Raters independently screened, extracted data, and assessed risk of bias in duplicate. We synthesized intervention effects using frequentist and Bayesian random-effects models. The GRADE approach determined the quality of evidence. RESULTS: Twenty-three randomized controlled trials including 1957 adult and pediatric patients sensitized primarily to house dust mite showed that add-on SCIT and SLIT have similar relative and absolute effects and likely result in important improvements in AD severity, defined as a 50% reduction in SCORing Atopic Dermatitis (risk ratio [95% confidence interval] 1.53 [1.31-1.78]; 26% vs 40%, absolute difference 14%) and QoL, defined as an improvement in Dermatology Life Quality Index by 4 points or more (risk ratio [95% confidence interval] 1.44 [1.03-2.01]; 39% vs 56%, absolute difference 17%; both outcomes moderate certainty). Both routes of AIT increased adverse events (risk ratio [95% confidence interval] 1.61 [1.44-1.79]; 66% with SCIT vs 41% with placebo; 13% with SLIT vs 8% with placebo; high certainty). AIT's effect on sleep disturbance and eczema flares was very uncertain. Subgroup and sensitivity analyses were consistent with the main findings. CONCLUSIONS: SCIT and SLIT to aeroallergens, particularly house dust mite, can similarly and importantly improve AD severity and QoL. SCIT increases adverse effects more than SLIT. These findings support a multidisciplinary and shared decision-making approach to optimally managing AD.

Recent Advances in Phytochemical-Based Topical Applications for the Management of Eczema: A Review.

Eczema (atopic dermatitis, AD) is a skin disease characterized by skin barrier dysfunction due to various factors, including genetics, immune system abnormalities, and environmental triggers. Application of emollients and topical drugs such as corticosteroids and calcineurin inhibitors form the mainstay of treatments for this challenging condition. This review aims to summarize the recent advances made in phytochemical-based topical applications to treat AD and the different carriers that are being used. In this review, the clinical efficacy of several plant extracts and bioactive phytochemical compounds in treating AD are discussed. The anti-atopic effects of the herbs are evident through improvements in the Scoring Atopic Dermatitis (SCORAD) index, reduced epidermal thickness, decreased transepidermal water loss, and alleviated itching and dryness in individuals affected by AD as well as in AD mouse models. Histopathological studies and serum analyses conducted in AD mouse models demonstrated a reduction in key inflammatory factors, including thymic stromal lymphopoietin (TSLP), serum immunoglobulin E (IgE), and interleukins (IL). Additionally, there was an observed upregulation of the filaggrin (FLG) gene, which regulates the proteins constituting the stratum corneum, the outermost layer of the epidermis. Carriers play a crucial role in topical drug applications, influencing dose delivery, retention, and bioavailability. This discussion delves into the efficacy of various nanocarriers, including liposomes, ethosomes, nanoemulsions, micelles, nanocrystals, solid-lipid nanoparticles, and polymeric nanoparticles. Consequently, the potential long-term side effects such as atrophy, eruptions, lymphoma, pain, and allergic reactions that are associated with current topical treatments, including emollients, topical corticosteroids, topical calcineurin inhibitors, and crisaborole, can potentially be mitigated through the use of phytochemical-based natural topical treatments.

Serum Concentration of IL-5 Receptor (IL-5R) and Associations with Disease Severity in Patients with Chronic Spontaneous Urticaria (CSU) and Atopic Dermatitis (AD).

The immunological pathogenesis of atopic dermatitis (AD) and chronic spontaneous urticaria (CSU) has not been fully elucidated yet. The aim of our research was to assess the serum concentration of interleukin-5 receptor (IL-5R) in relation to the disease activity and pruritus intensity in adult patients with AD and CSU. This pilot study included 45 participants (15 patients with AD, 15 patients with CSU, and 15 healthy controls). Blood samples were taken to examine the serum levels of IL-5R using the enzyme-linked immunosorbent assay (ELISA) test. The Scoring Atopic Dermatitis (SCORAD) index, the Urticaria Activity Score (UAS7), and the Visual Analogue Scale (VAS) were used to assess the disease activity and the pruritus intensity, respectively. Obtained results revealed that the IL-5R concentration was significantly higher in patients with CSU than in patients with AD and in the controls (p = 0.038). There was a positive correlation between the IL-5R level and the SCORAD index in patients with AD (r = -0.9, p = 0.047), which was not found for the CSU activity by UAS7 and with the pruritus severity by VAS in both examined groups of patients. Our findings underscore higher serum levels of IL-5R among CSU and AD patients, which may highlight its functional role in the pathogenesis of these diseases. In contrast, IL-5R might not be fully useful in reflecting the severity of symptoms. Although our results are promising, this study should be conducted on a larger cohort of patients.

Guidelines for the Management of Atopic Dermatitis in Children: A Systematic Review.

INTRODUCTION: Numerous guidelines have been published for atopic dermatitis management in children in recent years. To date, the quality of the newest guidelines has not been appraised. This study aimed to identify and evaluate guidelines for the management of atopic dermatitis in children. METHODS: We reviewed the literature retrieved from PubMed, Web of Science, Ovid, ScienceDirect, Embase, China National Knowledge Infrastructure, WanFang Data, and guidelines websites. Search period from January 1, 2016, to December 31, 2021. The following keywords were used for searching: "atopic dermatitis," "atopic eczema," "eczema," "guideline," and "consensus." The quality of the guidelines was assessed by two assessors using the Appraisal of Guidelines for Research & Evaluation II (AGREE II) instrument independently, and domain scores >60% were considered to have sufficient quality. The guideline recommendations were reviewed. RESULTS: Nineteen guidelines were included in the study. Three guidelines had a graded A level, which was recommended for use in practice. Eleven guidelines had a graded B level, which was recommended for use in revision. The remaining five guidelines were rated with C level, which was not recommended. The average score of six domains of AGREE II was 64.76%, 48.53%, 42.35%, 73.83%, 32.23%, and 70.17%, respectively. A consistency test showed an intraclass correlation coefficient range of 0.497 (95% CI: 0.105, 0.705) to 0.970 (95% CI: 0.93, 0.987) based on the two assessors' test results for the guidelines. CONCLUSIONS: Most guidelines were recommended for use with revision. No significant changes were observed in the primary management of atopic dermatitis in children compared to previous evidence. New biological agents and complementary alternative medicine are increasingly available, but the evidence for the treatment of atopic dermatitis in children is still limited.

Prevalence and burden of atopic dermatitis involving the head, neck, face, and hand: A cross sectional study from the TARGET-DERM AD cohort.

BACKGROUND: Atopic dermatitis (AD) is severely burdensome, and there has been poor characterization of any differences in impact based on the area affected. OBJECTIVE: To estimate the prevalence and HRQoL impact of head/face/neck/hand (HFNH) involvement among patients with moderate-to-severe atopic dermatitis. METHODS: All TARGET-DERM AD registry patients with moderate/severe Investigator Global Assessment (vIGA-AD) were assessed using the Patient Oriented SCORing Atopic Dermatitis, Patient Oriented Eczema Measure (POEM) and the (Children's) Dermatology Life Quality Index ((C)DLQI). RESULTS: 541 participants met the criteria (75.0% adults) and 84% (N = 453) reported HFNH involvement. HFNH and non-HFNH involved participants had similar characteristics; 55.2% female and 46.9% White. Compared to the non-HFNH involved, the involved had severe vIGA-AD (28.5% vs 16.3%, P = .02) and higher median body surface area affected (15% vs 10%, P ≤ .01) and were twice as likely to have higher (C)DLQI and POEM scores. LIMITATIONS: This was an analysis of real-world and patient reported outcome data. CONCLUSION: Real-world HFNH involved AD patients were associated with significantly worse quality of life, POEM/(C)DLQI, and more severe disease. Detailed assessments of specific areas affected by AD are needed to personalize treatment.

The prevalence of sensitization to food allergens in children with atopic dermatitis.

INTRODUCTION: Atopic dermatitis (AD) has a complex pathophysiology. The course of the disease is affected by both environmental factors and allergen hypersensitivities. Food and aeroallergens have a significant role in the pathogenesis and disease control. OBJECTIVE: In this study, it was aimed to determine the prevalence of food and aeroallergen sensitivity of children with AD. METHODS: Children under 18 years with AD who applied to pediatric allergy and immunology outpatient clinics were evaluated. All patients had a skin prick test (SPT) within most common food and aeroallergens. RESULTS: One hundred seventy three patients were studied. Most of the moderate and severe AD patients were boys (boys 64% vs. girls 47%). Symptoms started earlier and positive results in SPTs with food allergens were more common in patients with SCORAD (SCORing Atopic Dermatitis) >25 (p < 0.0001). Egg white (39%), egg yolk (31%), cow's milk (13%) and wheat flour (5%), were the most common allergens, respectively. The SCORAD scores were higher in multiple food sensitized patients' groups (p < 0.001). Although, food sensitizations were prevalent in patients who had higher SCORAD scores (p = 0.001), there was no significant difference in sensitization with aeroallergens. (p = 0.392). CONCLUSION: Sensitizations to both food and aeroallergens are common in patients with AD. In addition, sensitization to these allergens and SCORAD severity in patients with AD have positive correlation.

Therapeutic effects elicited by the probiotic Lacticaseibacillus rhamnosus GG in children with atopic dermatitis. The results of the ProPAD trial.

BACKGROUND: Atopic dermatitis (AD) is a chronic inflammatory skin disease affecting up to 20% of the pediatric population associated with alteration of skin and gut microbiome. Probiotics have been proposed for AD treatment. The ProPAD study aimed to investigate the therapeutic effects of the probiotic Lacticaseibacillus rhamnosus GG (LGG) in children with AD. METHODS: In total, 100 AD patients aged 6-36 months were enrolled in a randomized, double-blind, controlled trial to receive placebo (Group A) or LGG (1 x 1010 CFU/daily) (Group B) for 12 weeks. The primary outcome was the evaluation of the efficacy of LGG supplementation on AD severity comparing the Scoring Atopic Dermatitis (SCORAD) index at baseline (T0) and at 12-week (T12). A reduction of ≥8.7 points on the SCORAD index was considered as minimum clinically important difference (MCID). The secondary outcomes were the SCORAD index evaluation at 4-week (T16) after the end of LGG treatment, number of days without rescue medications, changes in Infant Dermatitis Quality Of Life questionnaire (IDQOL), gut microbiome structure and function, and skin microbiome structure. RESULTS: The rate of subjects achieving MCID at T12 and at T16 was higher in Group B (p < .05), and remained higher at T16 (p < .05)The number of days without rescue medications was higher in Group B. IDQOL improved at T12 in the Group B (p < .05). A beneficial modulation of gut and skin microbiome was observed only in Group B patients. CONCLUSIONS: The probiotic LGG could be useful as adjunctive therapy in pediatric AD. The beneficial effects on disease severity and quality of life paralleled with a beneficial modulation of gut and skin microbiome.

Mild to moderate atopic dermatitis severity can be reliably assessed using smartphone-photographs taken by the patient at home: A validation study.

BACKGROUND: The use of photographs to diagnose and monitor skin diseases is gaining ground. OBJECTIVES: To investigate the validity and reliability of photographic assessments of atopic dermatitis (AD) severity. METHODS: AD severity was evaluated in the clinic by two assessors using the Eczema Area and Severity Index (EASI), SCOring Atopic Dermatitis (SCORAD), and Investigator's Global Assessment (IGA). Participants photographed the lesions with their own smartphone and completed a questionnaire about the extent of eczema the same day from home. The photographs were assessed twice with an 8 weeks interval by five dermatologists experienced in photographic evaluations. Intraclass correlation coefficients (ICC) with 95% confidence interval (CI) were applied. RESULTS: Seventy-nine participants were enrolled. The ICC between clinical EASI and photographic EASI was 0.88 (95% CI 0.81-0.93), and 0.86 (0.70-0.93) between clinical SCORAD and photographic SCORAD. Perfect agreement between clinical IGA and photograph IGA was observed for 62%, with the difference between the two never deviating with more than 1 score. The inter-rater ICC for photographic EASI and photographic SCORAD, respectively, was 0.90 (0.85-0.94), and 0.96 (0.91-0.98). The intra-rater agreements between the first and second assessments varied from 0.95 to 0.98 for photographic EASI, and from 0.86 to 0.94 for photographic SCORAD. CONCLUSION: There was high agreement between mild to moderate AD severity assessed clinically and based on smartphone photographs. Further, the photographic assessments can be reproduced with high reliability.

Vitamin D, cytokine profiles, and disease severity in infants with atopic dermatitis: a single centre, cross-sectional study.

Introduction: Atopic dermatitis (AD) is an immune-mediated inflammatory skin disease and generally develops in infancy. Studies evaluating the role of vitamin D in immune mechanims in AD showed varying results. Aim: To assess the association between serum vitamin D, cytokine profiles, and disease severity in infants with AD. Material and methods: A cross-sectional study was conducted on infants aged 0-12 months with AD in the Paediatric Allergy and Immunology Department, Saiful Anwar Hospital, Indonesia. The disease severity was assessed by the Scoring of Atopic Dermatitis (SCORAD) index. Blood was drawn to evaluate the total eosinophil count (TEC), total immunoglobulin E (tIgE), 25-hydroxyvitamin D (25(OH)D), interleukin-4 (IL-4), IL-17A, and IL-22 levels. Results: This study enrolled 36 infants including 19 with mild AD and 17 with moderate AD. Vitamin D deficiency and insufficiency were found in 18 (50%) and 9 (25%) subjects, respectively. The mean 25(OH)D level was lower and the mean IL-4, IL-17A, and IL-22 levels were higher in the moderate AD group than in the mild AD group (p < 0.05). A lower level of 25(OH)D was associated with a higher level of IL-17A (r = -0.315, p = 0.041). The SCORAD index was negatively correlated with 25(OH)D (r = -0.714, p < 0.001) and positively correlated with IL-17A (r = 0.522, p = 0.001) and IL-22 (r = 0.612, p < 0.001) but not IL-4 (r = 0.325, p = 0.053). Conclusions: There was a high prevalence of vitamin D deficiency and insufficiency in infants with AD, and a low vitamin D level was correlated with the severity of AD, dependently on IL-17A.

Predictive biomarker modeling of pediatric atopic dermatitis severity based on longitudinal serum collection.

The pathogenesis of atopic dermatitis (AD) results from complex interactions between environmental factors, barrier defects, and immune dysregulation resulting in systemic inflammation. Therefore, we sought to characterize circulating inflammatory profiles in pediatric AD patients and identify potential signaling nodes which drive disease heterogeneity and progression. We analyzed a sample set of 87 infants that were at high risk for atopic disease based on atopic dermatitis diagnoses. Clinical parameters, serum, and peripheral blood mononuclear cells (PBMCs) were collected upon entry, and at one and four years later. Within patient serum, 126 unique analytes were measured using a combination of multiplex platforms and ultrasensitive immunoassays. We assessed the correlation of inflammatory analytes with AD severity (SCORAD). Key biomarkers, such as IL-13 (rmcorr=0.47) and TARC/CCL17 (rmcorr=0.37), among other inflammatory signals, significantly correlated with SCORAD across all timepoints in the study. Flow cytometry and pathway analysis of these analytes implies that CD4 T cell involvement in type 2 immune responses were enhanced at the earliest time point (year 1) relative to the end of study collection (year 5). Importantly, forward selection modeling identified 18 analytes in infant serum at study entry which could be used to predict change in SCORAD four years later. We have identified a pediatric AD biomarker signature linked to disease severity which will have predictive value in determining AD persistence in youth and provide utility in defining core systemic inflammatory signals linked to pathogenesis of atopic disease.

Efficacy and safety of dupilumab for moderate-to-severe atopic dermatitis: A systematic review for the EAACI biologicals guidelines.

This systematic review evaluates the efficacy, safety and economic impact of dupilumab compared to standard of care for uncontrolled moderate-to-severe atopic dermatitis (AD). Pubmed, EMBASE and Cochrane Library were searched for RCTs and health economic evaluations. Critical and important AD-related outcomes were considered. The risk of bias and the certainty of the evidence were assessed using GRADE. Seven RCTs including 1845 subjects >12 years treated with dupilumab 16 to 52 weeks were evaluated. For adults, there is high certainty that dupilumab decreases SCORAD (MD -30,72; 95% CI -34,65% to -26,79%) and EASI-75 (RR 3.09; 95% CI 2.45 to 3.89), pruritus (RR 2.96; 95% CI 2.37 to 3.70), rescue medication (RR 3.46; 95% CI 2.79 to 4.30), sleep disturbance (MD -7.29; 95% CI -8.23 to -6.35) and anxiety/depression (MD -3.08; 95% CI -4.41 to -1.75) and improves quality of life (MD -4.80; 95% CI -5.55 to -4.06). The efficacy for adolescents is similar. Dupilumab-related adverse events (AEs) slightly increase (low certainty). The evidence for dupilumab-related serious AE is uncertain. The incremental cost-effectiveness ratio ranged from 28 500 £ (low certainty) to 124 541 US$ (moderate certainty). More data on long-term safety are needed both for children and for adults, together with more efficacy data in the paediatric population. Registration: PROSPERO (CRD42020153645).

Rice flour fermented with Lactobacillus paracasei CBA L74 in the treatment of atopic dermatitis in infants: A randomized, double- blind, placebo- controlled trial.

To assess the effect of a fermented rice-flour obtained from Lactobacillus paracasei CBA L74 in managing infants with moderate to severe atopic dermatitis. Infants with moderate to severe atopic dermatitis, aged 6-36 months, were randomly assigned to receive once-daily consumption of rice flour containing heat-killed probiotic Lactobacillus paracasei CBA L74 or placebo for 12 weeks as supplementary approach to topical treatment. Primary outcome was SCORAD index change from baseline to 12 weeks; secondary outcomes were gut microbiota composition, as evaluated by the analysis of fecal samples, and serum cytokines at baseline and at the end of the intervention period in both groups, and steroid usage over the treatment period and one month after stopping it. V3-V4 region of the 16S ribosomal RNA gene was sequenced to evaluate changes in the gut microbiota. SCORAD index decreased over the treatment period in both groups. The difference in the SCORAD change was -2.1 (-5.5 to 1.3; p = 0.223) for the experimental vs. the placebo group, not reaching the minimal clinical difference of 8.7 units. The use of topical steroids, measured as finger tips units, decreased from 4 to 16 weeks, in both groups; the reduction was significantly higher in experimental than in placebo group (p value from Wilcoxon rank sum test = 0.031). No significant differences were observed for cytokines levels between groups. The composition of gut microbiota at the phylum and class taxonomic levels resulted very similar, at baseline and after intervention, in both groups. Similarly, no significant differences were observed in the relative abundance of bacterial genera between groups. In conclusion, though the heat-killed Lactobacillus paracaseiwas not proved to be effective in reducing the severity of atopic dermatitis, it showed a steroid sparing effect the value of which needs to be further investigated.

Infantile atopic dermatitis: Serum vitamin D, zinc and TARC levels and their relationship with disease phenotype and severity.

BACKGROUND: Several markers that influence the clinical course of atopic dermatitis (AD) have been investigated so far. Thymus and activation regulated chemokine (TARC) - a Th2-related cytokine - increase in various atopic diseases. It has been shown that vitamin D affects Treg cells and immune responses. Zinc as an essential trace element for cell-cell interactions, cellular differentiation, and proliferation. However, the effect of these markers on infantile AD and disease severity are mostly unknown. OBJECTIVE: The aim of this study was to investigate the relationship between TARC, vitamin D, zinc levels, and the disease severity in infants with AD. METHOD: AD patients (n = 160) with age and sex that matched healthy controls (n = 79) were included in the study. The diagnosis of AD was made based on the Hanifin-Rajka criteria. The objective SCORAD index was used for the assessment of disease severity. RESULTS: A total of 160 patients (male 71.9%) with AD were included in the study. The median age of onset of symptoms was 2 (1.0-3.5) months. The lesions initially started on face 76.9%, neck 6.9%, extremities 7.5%, and body 8.8%. Nearly 40% of the patients were found to be atopic. Food allergy was found in 39.4%. The median of objective SCORAD index was 27.5 (17.5-40) in the study group. The TARC levels of AD patients were higher than control group [1803 pg/ml (1006- 3123) vs 709 pg/ml (504-1147), p < 0.001] There was a significant correlation between objective SCORAD scores and TARC values in subjects with AD (r = 0.363, p < 0.001). As the severity of AD increased, vitamin D levels decreased (p for trend 0.015) and TARC values increased (p for trend < 0.001). Serum zinc levels did not change with the severity of the disease. The presence of atopy did not have an influence on serum TARC, zinc, and vitamin D levels. CONCLUSION: In infants with AD, disease severity is positively related with TARC levels; and inversely proportional to vitamin D levels. TARC levels differ between patients and healthy controls. The presence of atopy has not been shown to affect these markers. © 2021 Codon Publications. Published by Codon Publications.

Effect of topical marshmallow (Althaea officinalis) on atopic dermatitis in children: A pilot double-blind active-controlled clinical trial of an in-silico-analyzed phytomedicine.

Atopic dermatitis (AD) is a chronic relapsing eczematous skin disease, which primarily affects infants and young children. Due to the side effects of commonly used drugs for its treatment, the development of safer therapeutic strategies is needed. There are many reports on the topical use of marshmallow (Althaea officinalis) for a range of skin diseases in Persian medicine. The main aim of the present investigation was evaluating the efficacy of marshmallow in children with mild-to-moderate atopic dermatitis. Another aim of the study was screening the anti-allergic and anti-inflammatory potential of phytocomponents against target proteins, including TNF-alpha, IL6, and PDEs A, B, and D enzymes with PDB IDs: 2AZ5, 1P9M, 3I8V, 4KP6, and 1Y2K, respectively, along with their respective standard ligands using computational docking analysis. A pilot clinical trial was designed to investigate the safety and efficacy of Althaea officinalis in children with AD. The diagnosis of AD was made according to the criteria of Hanifin and Rajka. Children between 3 months and 12 years old were participated in this trial and randomly allocated into two parallel intervention and control groups. The intervention group used Althaea officinalis 1% ointment while the positive control group used Hydrocortisone 1% ointment twice a day for a week and after that, three times per week for a period of 3 weeks. The severity of AD was measured using the SCORAD score at the end of each assessment visits. A total number of 22 patients completed the study. A significant decrease of the SCORAD score was observed in both groups. At the end of the study, this score change, which indicates the improvement of the patients was significantly higher in the intervention group in comparison to the baseline (p-value = .015) and week 1 (p-value = .018). In the docking analysis of the study, 33 phytochemical compounds were identified, which were docked into the active site of IL6, TNF-alpha, and human PDE4 isoenzymes. Affinity toward the selected enzymes was significantly higher in glycosylated compounds. The results of this pilot study showed that the efficacy of Althaea officinalis 1% ointment in a decrease of disease severity is more than Hydrocortisone 1% in children with AD. However, further studies are needed to confirm this finding. Moreover, the docking analysis revealed that the inhibitory activity of compounds with free hydroxyl groups such as glycosylated compounds was better than others, probably due to the hydrogen bond interaction of hydroxyl groups of the ligands with the enzymes.

Common Atopic Dermatitis Rating Scales: A Practical Approach and Brief Review [Formula: see text].

Atopic dermatitis (AD) severity measurement scales are important in clinical trials as objective outcome measures and are often required for government and private insurance plans. These scales are sometimes underused by clinicians due to a variety of factors including time constraints and lack familiarity. We conducted a literature review on the most commonly used AD measurement scales and provide succinct user guides and scoring explanations, advantages and disadvantages, and interscale comparisons.

Efficacy and safety of the histamine H4 receptor antagonist ZPL-3893787 in patients with atopic dermatitis.

BACKGROUND: H4 receptor antagonists are potential novel treatments for inflammatory skin diseases, including atopic dermatitis (AD). OBJECTIVE: We sought to study the efficacy and safety of ZPL-3893787 (a selective H4 receptor antagonist) in patients with moderate-to-severe AD. METHODS: A randomized, double-blind, placebo-controlled, parallel-group study was conducted to evaluate ZPL-3893787 (30 mg) once-daily oral therapy in adults with moderate-to-severe AD. Patients were randomized (2:1) to ZPL-3893787 (n = 65) or placebo (n = 33) for 8 weeks. Patients had a history of AD for more than 12 months, Eczema Area and Severity Index (EASI) scores of 12 or greater and 48 or less, Investigator's Global Assessment (IGA) scores of 3 or greater, pruritus scores of 5 or greater (0- to 10-point scale), and AD on 10% or greater of body surface area. Efficacy parameters included EASI, IGA, SCORAD, and pruritus assessment. RESULTS: Treatment with oral ZPL-3893787 showed a 50% reduction in EASI score compared with 27% for placebo. The placebo-adjusted reduction in EASI score at week 8 was 5.1 (1-sided P = .01). Clear or almost-clear IGA scores were 18.5% with ZPL-3893787 versus 9.1% with placebo. SCORAD scores exhibited 41% reduction with ZPL-3893787 versus 26% with placebo (placebo-adjusted reduction of 10.0, P = .004). There was a 3-point reduction (scale, 1-10) in pruritus with ZPL-3893787, but there was a similar reduction with placebo, resulting in a nonsignificant difference (P = .249). Patient-reported pruritus subscores obtained from SCORAD were reduced with ZPL-3893787 compared with placebo at week 8 (nonsignificant). ZPL-3893787 was well tolerated. CONCLUSION: For the first time, these results showed that ZPL-3893787 improved inflammatory skin lesions in patients with AD, confirming H4 receptor antagonism as a novel therapeutic option.

Les scores d'évaluation de la dermatite atopique: Outcome measures for atopic dermatitis.

Scores evaluating the severity of atopic dermatitis are less well known and less used in daily practice of dermatologists than those for psoriasis, but things are changing. Indeed, the numerous trials and therapeutic advances in the field of eczema have also imposed the use of scales to objectively assess the severity of the disease and its improvement with treatment. The scores were initially numerous and poorly validated, but there is currently a trends towards simplification and standardization, with the work in particular of the Harmonizing Outcome Measures for Eczema (HOME) group. Scores for objective clinical signs, patient-reported symptoms, quality of life, and long-term disease control are now considered to be the core outcome set. The most used scores are detailed in this article. © 2020 Elsevier Masson SAS. All rights reserved.

Is the presence of a fur animal an exacerbating factor of atopic dermatitis in adults?

Atopic dermatitis is one of the most common inflammatory dermatoses in children and adults. To date, no clear relationship between the severity of AD and the exposure to dog and guinea pig-derived allergens has been established. AIM: The aim of the study was to assess the association between the specific serum immunoglobulin E levels (against dog and guinea pig) and the grade of skin symptoms measured with the SCORAD and VAS scales in the population of adult patients suffering from atopic dermatitis. MATERIALS AND METHODS: The study was performed in the group of 47 patients suffering from atopic dermatitis since infancy (30 women and 17 men). Concentration of IgE was measured by the fluoroenzymatic immunoassay. The Mann-Whitney's test was used to compare the distribution of specific IgE concentration and the distribution of atopic dermatitis grade. RESULTS: The statistically significant correlation between SCORAD and VAS scales, and the measured specific IgE concentrations for investigated fur animals was found. CONCLUSIONS: The study demonstrated that in the patients with atopic dermatitis the concentration of specific IgE was correlated with severity of the disease symptoms, including itch. This enables forecasting the course of the disease and selecting a group of patients who should immediately reduce their contact with allergen.
