ABSTRACT

Variations in the epidemiology, clinical presentation, and disease course in atopic dermatitis (AD) patients with Skin of Color (SOC) compared with white counterparts have been reported. In this study, we evaluated the capability of a new imaging device (SkinCam) in quantifying skin texture changes in diverse patients, presenting with AD or xerosis, after using a prebiotic skincare routine over 10 weeks.  A total of 39 subjects from diverse racial/ethnic backgrounds, aged 3 to 76 years old, with Fitzpatrick skin phototypes I to VI, presenting with mild AD and moderate to severe xerosis, were enrolled in the study. All subjects used a prebiotic cleanser on its own for 2 weeks, followed by a prebiotic moisturizer in conjunction for an additional 8 weeks. Standardized images of the subjects' legs were taken with SkinCam at several time points (baseline, week 2, and week 10), and analyzed for skin texture parameters. Our results demonstrate that both skin texture irregularity and skin color patterns significantly improve over time with a prebiotic skincare regimen in AD (n=12) and xerosis (n=24) subjects. Interestingly, image analyses showed more improvement over time in xerosis and AD SOC patients (n=18, Fitzpatrick IV-VI). Lastly, skin texture analyses from SkinCam imaging correlated with clinical assessments, showing significant improvement by prebiotic skincare regimen in all subjects by week 10. In summary, our results demonstrate that the SkinCam imaging device has the capability to effectively monitor skin texture parameters over time in both AD and xerosis patients with lightly and darkly pigmented skin. J Drugs Dermatol. 2024;23(7):557-563.  doi:10.36849/JDD.8371.

ABSTRACT

Dermatologists routinely see patients with inflammatory skin conditions and aesthetic concerns that involve substantial psychological comorbidity. However, most dermatologists do not receive formal training in this area, and many are unsure how to best help treat certain patients holistically. Body dysmorphic disorder (BDD) is a common and distressing psychiatric condition that disproportionately impacts dermatology patients, including patients living with chronic inflammatory skin conditions such as acne and atopic dermatitis. BDD is characterized by preoccupation with nonexistent or minimally noticeable flaws in physical appearance that cause clinically significant distress or impairment in functioning. Adolescent populations may be particularly vulnerable to clinically significant body image dissatisfaction, including BDD, due to the high prevalence of acne and the pervasive role of social media platforms. The rise of social media may exacerbate body image issues through repetitive exposure to idealized and often unrealistic beauty standards. Though screening questionnaires can assist dermatologists in recognizing BDD, dermatologists must collaborate with mental health providers to provide comprehensive care to vulnerable patients, including adolescents.J Drugs Dermatol. 2024;23(7):545-550.  doi:10.36849/JDD.8156.

ABSTRACT

Atopic dermatitis (AD) is a chronic skin condition that can manifest in childhood and persist into adulthood or can present de novo in adults. The clinical presentation of adults with AD may differ among those with pediatric-onset versus adult-onset disease and potential differences between both groups remain to be better characterized. These atypical features might not be encompassed as part of current diagnostic criteria for AD, such as the Hanifin-Rajka (H-R) and the U.K. Working Party (UKWP) criteria. We conducted a retrospective chart review of the electronic medical records of a large, single, academic center to compare the clinical characteristics between adult-onset and pediatric onset AD and examine the proportion of patients who meet the H-R and/or UKWP criteria. Our single-center retrospective chart review included adults (≥ 18 years of age) with any AD-related ICD-10 codes, ≥ 2 AD-related visits, and a recorded physician-confirmed AD diagnosis. Descriptive statistics were used to compare adults with pediatric-onset (< 18 years of age) and adult-onset (≥ 18 years of age) AD. Logistic regression and x2 test were used to compare groups. We found that, compared to pediatric-onset AD, adults with adult-onset AD had less flexural involvement, flexural lichenification and a personal and family history of other atopic diseases. Compared to adults with pediatric-onset AD, adults with adult-onset AD had greater involvement of the extensor surfaces and more nummular eczema compared to pediatric-onset AD. In our cohort, adults with adult-onset AD were less likely to meet H-R and UKWP criteria compared to pediatric-onset AD. Adults with adult-onset AD may present with a clinical presentation that is different from those with pediatric-onset AD, which may not be completely captured by current AD criteria such as the H-R and UWKP criteria. This can lead to possibly mis- or underdiagnosing AD in adults. Thus, understanding the differences and working towards modifying criteria for adult-onset AD has the potential to improve accurate diagnosis of adults with AD.

ABSTRACT

Atopic dermatitis (AD) is a chronic, recurring, inflammatory skin condition. Xerosis, pruritus, and rash make the clinical diagnosis. Adequate skin care and regular emollient use are key in management. Topical corticosteroids are the first-line treatment for AD flare-ups. Wet wrap therapy can improve AD severity and extent. Topical calcineurin inhibitors are second-line treatments. Emollient use, topical corticosteroids and calcineurin inhibitors, and bleach baths can help prevent flare-ups. Patients with refractory AD that might require immunomodulatory treatments, such as dupilumab (Dupixent), Janus kinase inhibitors, or phototherapy, should be referred to a dermatologist. Seborrheic dermatitis (SD) is a common, chronic, relapsing, inflammatory condition that involves sebaceous skin areas. Infection with Malassezia species and the inflammatory response to it are the probable etiologies. The clinical diagnosis is made by the presence of hallmark greasy, yellow scales on the scalp or face. Infantile SD most commonly involves the scalp and forehead and typically is self-limited. In infants, application of emollients followed by hair brushing and shampooing may be effective. In infants and children, if the condition does not improve with this treatment, topical ketoconazole shampoo, gel, or lotion is safe and effective. Refractory cases of SD can be managed with topical corticosteroids and calcineurin inhibitors.

ABSTRACT

OBJETIVES: Obtain a version to validate it in a population of adults with AD. MATERIALS AND METHODS: 1) Translation into Spanish and cross-cultural adaptation of the questionnaire from the original version in English, through a seven-step process. 2) Evaluation of the unidimensionality of the resulting scale by means of an exploratory factor analysis (EFA), of its reliability by means of Cronbach's alpha coefficient, and of its validity by evaluating the correlation of its score with those of the POEM and DLQI questionnaires. (external reference criteria). RESULTS: The version resulting from the translation and cross-cultural adaptation process was well understood by the target population. The AFE of the 66 questionnaires documented the unidimensionality of the scale based on compliance with all the criteria used for its verification. Its reliability was excellent (Cronbach's Alpha: 0.917) and its score had a very high correlation with the external reference criteria (POEM: Spearman's Rho 0.85; p < 0.0001; DLQI Spearman's Rho = 0.81; p < 0 .0001). CONCLUSIONS: The version translated into Spanish and adapted for transculturation of the ADCT questionnaire has appropriate psychometric characteristics, which will contribute to optimizing the care processes of Spanish-speaking patients.

ABSTRACT

A Swedish translation of the patient-reported outcome measure for assessing long-term control of atopic dermatitis, Recap of atopic eczema (RECAP), has not been validated. Cross-cultural translation and multi-centre validation of the translated RECAP questionnaire were therefore performed. Disease severity was assessed using the validated Investigator Global Assessment Scale for atopic dermatitis (vIGA-ADTM). The Swedish RECAP was completed by 208 individuals aged 16 years or older with a median age of 36 years (interquartile range [IQR] 27-48). The participants considered the questionnaire suitable for assessing eczema control. The median RECAP score (range 0-28) was 12 (IQR 5-19). The mean and median vIGA-ADTM scores (range 0-4) were 2 (standard deviation [SD] 2) and 3 (IQR 2-4), respectively. A correlation between RECAP and the vIGA-ADTM was observed (p < 0.001). There was no significant change in scores for participants who answered the questionnaire twice within 14 days. Over time, improved or worsened eczema, as evaluat-ed by vIGA-ADTM, affected RECAP scores significantly (p < 0.001). The study suggests that RECAP can assess AD control in a Swedish clinical setting and shows -acceptable reliability.

ABSTRACT

GENERAL PURPOSE: To review issues related to atopic dermatitis, including its classification, clinical presentation, potential triggers, and treatment options. TARGET AUDIENCE: This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and registered nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES: After participating in this educational activity, the participant will:1. Synthesize a differential diagnosis for atopic dermatitis (AD).2. Explain the classification of AD cases.3. Select triggers or exacerbating factors for AD.4. Explain pharmacologic and nonpharmacologic treatment options for patients with AD.


Atopic dermatitis is the most common eczematous inflammatory skin condition, presenting with lesions that typically appear as poorly demarcated erythematous and scaly papules and plaques. The lesions most commonly occur on flexural surfaces of the knees, elbows, and wrists and are associated with moderate to severe itching. This article focuses on the clinical presentation of atopic dermatitis and treatment options. Other related topics include epidemiology, pathogenesis, risk factors, triggers, and differential diagnoses.

ABSTRACT

The objective was to study a large, international, ethnically diverse population of patients with atopic dermatitis (AD) to support the creation of patient-centric recommendations for AD management. Qualitative data were generated from 45-min, 1:1 telephone interviews conducted across 15 countries in each patient's native language. Interviews explored the impact of AD on patients' lives, patients' most important symptoms, treatment expectations, and treatment decision-making. Participants were also questioned on their current knowledge of AD scoring systems and what was most important to include in these tools. In total, 88 adult patients (≥ 18 years old) receiving treatment for AD were recruited through a market research database, clinician referrals, and local advertising. All patients were screened to ensure a balanced and diverse sample in terms of age, gender, educational level, employment status, geographic location, and AD severity. Patients involved in market research or activities supporting advocacy groups within the previous 6 months or affiliated with or employed by pharmaceutical companies were excluded. AD had a substantial impact on patients' lives. Itch, skin redness, and dry/flaky skin were the most frequently reported symptoms, with > 75% of patients experiencing these symptoms every 1-3 days. Mental health issues were common and resulted in the greatest negative impact on patients' daily lives. Patients perceived clinicians to underestimate the burden of their AD. Patients had little awareness of AD scoring systems and indicated a preference for these to be more clearly incorporated in clinical practice. For an ideal scoring system, patients favored using a combination of patient-reported and clinician-reported outcomes to reflect disease burden and ensure consistency across all settings. This global study generated diverse patient perspectives on the disease burden of AD, their expectations of treatment, and their views on AD scoring methods. These data provide evidence to support the development of patient-centric recommendations for AD management.

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.

ABSTRACT

BACKGROUND: Asthma is one of the most well-recognized comorbidities of atopic dermatitis (AD). However, the relationship of AD severity and morphology with asthma characteristics in adults is not well defined. OBJECTIVES: To understand associations of AD severity and morphology with comorbid asthma age-of-onset and control in adults with AD. METHODS: A cross-sectional, dermatology practice-based study was performed in adults (≥ 18 years) with AD and history of asthma (N = 252). Self-administered electronic questionnaires were completed by patients, including demographics, patient-reported outcomes measures of AD severity, history of asthma, age-of-onset, and Asthma Control Test (ACT). Multivariable logistic regression models were constructed to examine relationships between AD severity and morphology with asthma age-of-onset and control. RESULTS: The mean ± standard deviation ACT score was 21.7 ± 4.3 (range 5-25), with 55 (21.8%) having ACT scores ≤ 19 indicating poorly controlled asthma. AD severity and morphology were not associated with adult-onset asthma or poor asthma control. CONCLUSIONS: AD severity and morphology were not consistently associated with comorbid asthma age-of-onset or control in adults with AD.

ABSTRACT

Studies examining the real-world treatment satisfaction in adults with atopic dermatitis (AD) and the physicians who treat adults with AD are scarce. We sought to characterize treatment satisfaction of adults with AD and physicians' perceived patient satisfaction with AD treatment. We performed a cross-sectional study of adults > = 18 years of age (modified AD UK Working Party Criteria, age onset < = 18 [N = 767]) with AD and a parallel-physician survey among allergists/immunologists [N = 148], dermatologists [N = 149] and primary care medicine [N = 104]. Logistic regression models were used to examine factors associated with patient treatment satisfaction (PTS) or physician-perceived patient treatment satisfaction (pPTS). Factors associated with increased PTS included female, older age, and receiving a written eczema action plan (EAP). Severe AD, itch, pain, and insomnia, greater impact on partner relationships, feeling not adequately informed about AD causes, and being separated, never married, or living with a partner was associated with less PTS. From the physician's perspective, mild AD and development of EAP was associated with increase pPTS, whereas being in practice longer was associated with less pPTS. Limitations include the potential for misclassification of AD and the inability to match AD patients to individual physicians. Recognizing which factors are associated with treatment satisfaction can help inform counseling and decision-making strategies, including the use of an eczema action plan, and support patient-physician outcomes alignment.

ABSTRACT

Atopic dermatitis (AD) is one of the most common inflammatory diseases, and has a higher prevalence among females in adulthood. The aim of this observational, cross-sectional, survey-based study was to evaluate the impact of AD on the daily lives of adult women patients. A scientific committee composed exclusively of women constructed a specific questionnaire in partnership with the French Eczema Association. Severity of AD was evaluated with the Patient-Oriented Eczema Measure (POEM). A sample of 1,009 adult women (mean age ± standard deviation: 41.8 ± 14.2 years) with AD was identified from a representative sample of the French population (82% response rate 1,230 women surveyed). According to the POEM, 50.64% (n = 511) of subjects were identified as having mild AD, 39.35% (n = 397) moderate AD, and 10.01% (n = 101) severe AD. Overall, 67.7% (n = 682) reported that their eczema involved a visible area (face, neck or hands), and 19.6% (n = 198) a sensual area (breasts/chest, genital area or buttocks). Of the 720 women with menstrual cycles, exacerbations of AD were reported to occur mostly before (50.6%) and during (48.3%) menstruation. A small proportion of women, 7.3% (n = 74), reported being afraid of  becoming pregnant because of their eczema. If AD involvement was in a visible area it had a greater impact on romantic relationships, sexual relationships and occupation. If AD involvement was in a sensual area it had a greater influence on romantic relationships and sexuality. Particular attention should be given to patients with localization of AD on the face, neck or hands, as they have a higher risk of social exclusion. Moreover, these results should encourage health professionals to ask patients with AD about the possible involvement of sensual areas.

ABSTRACT

BACKGROUND: Canine atopic dermatitis (CAD) is a common genetically predisposed, inflammatory, and pruritic skin disorder that affects dogs globally. To date, there are no specific biomarkers available to diagnose CAD, and the current diagnosis is based on a combination of criteria including patient history, clinical signs, and exclusion of other relevant differential diagnoses. METHODS AND RESULTS: We examined the gene expression of phosphodiesterase 4D (PDE4D) in peripheral blood mononuclear cells (PBMCs), as well as miR-203 and miR-483 in plasma, in three groups: healthy dogs, CAD dogs, and other inflammatory pruritic skin diseases (OIPSD) such as pemphigus foliaceus, scabies, cutaneous lymphoma, and dermatophytosis. Our results showed that PDE4D gene expression in the CAD group is statistically higher compared to those in the healthy and OIPSD groups, suggesting PDE4D may be a specific marker for CAD. Nevertheless, no correlation was found between PDE4D gene expression levels and the lesion severity gauged by CAD severity index-4 (CADESI-4). We also showed that miR-203 is a generic marker for clinical dermatitis and differentiates both CAD and OIPSD inflammatory conditions from healthy controls. CONCLUSIONS: We show that PDE4D is a potential marker to differentiate CAD from non-atopic healthy and OIPSD while miR-203 may be a potential marker for general dermatologic inflammation. Future study of PDE4D and miR-203 on a larger scale is warranted.

ABSTRACT

BACKGROUND: Atopic dermatitis (AD), a highly pruritic, inflammatory skin disease, affects approximately 7% of adolescents globally. A topical formulation of ruxolitinib, a Janus kinase (JAK) 1/JAK2 inhibitor, demonstrated safety and efficacy among adolescents/adults in two phase 3 studies (TRuE-AD1/TRuE-AD2). OBJECTIVE: To describe safety and efficacy of 1.5% ruxolitinib cream versus vehicle and long-term disease control of ruxolitinib cream among adolescents aged 12-17 years from pooled phase 3 study data. METHODS: Patients [≥ 12 years old with AD for ≥ 2 years, Investigator's Global Assessment score (IGA) 2/3, and 3-20% affected body surface area (BSA) at baseline] were randomized 2:2:1 to ruxolitinib cream (0.75%/1.5%) or vehicle for 8 weeks of continuous use followed by a long-term safety (LTS) period up to 52 weeks with as-needed use. Patients originally applying vehicle were rerandomized 1:1 to 0.75%/1.5% ruxolitinib cream. Efficacy measures at week 8 included IGA treatment success (IGA-TS; i.e., score of 0/1 with ≥ 2 grade improvement from baseline), ≥ 75% improvement in Eczema Area and Severity Index (EASI-75), and ≥ 4-point improvement in itch numerical rating scale (NRS4). Measures of disease control during the LTS period included IGA score of 0 (clear) or 1 (almost clear) and percentage affected BSA. Safety was assessed throughout the study. RESULTS: Of 1249 randomized patients, 245 (19.6%) were aged 12-17 years. Of these, 45 patients were randomized to vehicle and 92 patients to 1.5% ruxolitinib cream. A total of 104/137 (75.9%) patients continued on 1.5% ruxolitinib cream in the LTS period [82/92 (89.1%) continued on 1.5% ruxolitinib cream; 22/45 (48.9%) patients on vehicle were reassigned to 1.5% ruxolitinib cream], and 83/104 (79.8%) of these patients completed the LTS period. At week 8, substantially more patients who applied 1.5% ruxolitinib cream versus vehicle achieved IGA-TS (50.6% versus 14.0%), EASI-75 (60.9% versus 34.9%), and NRS4 (52.1% versus 17.4%; P = 0.009). The mean (SD) reduction in itch NRS scores was significantly greater in patients applying 1.5% ruxolitinib cream versus vehicle from day 2 [- 0.9 (1.9) versus -0.2 (1.4); P = 0.03]. During the LTS period, mean (SD) trough steady-state ruxolitinib plasma concentrations at weeks 12/52 were 27.2 (55.7)/15.5 (31.5) nM. The percentage of patients achieving IGA score of 0 or 1 was sustained or further increased with 1.5% ruxolitinib cream; mean affected BSA was generally low (< 3%; i.e., mild disease). Through 52 weeks, application site reactions occurred in 1.8% of adolescent patients applying 1.5% ruxolitinib cream at any time; no patients had serious adverse events. There were no serious infections, malignancies, major adverse cardiovascular events, or thromboembolic events. CONCLUSIONS: Meaningful anti-inflammatory and antipruritic effects were demonstrated with 1.5% ruxolitinib cream in the subset of adolescent patients with AD, comparable with those observed in the overall study population; long-term, as-needed use maintained disease control and was well tolerated.

ABSTRACT

For dupilumab, real-world long-term follow-up data remain scarce, and studies on optimized treatment modes as well as drug survival rate and its predictors are lacking. To explore the effectiveness of different treatment modes of dupilumab and to understand the drug survival rates of dupilumab in China and its predictive factors. This retrospective study included patients with moderate-to-severe AD who received dupilumab treatment. Their clinical data were collected and analyzed. Compared with baseline, the SCORing Atopic Dermatitis (SCORAD), Eczema Area and Severity Index (EASI), numerical rating scale (NRS), and Atopic Dermatitis Control Tool (ADCT) scores significantly decreased at 12, 24, and 52 weeks (p < 0.0001), and the continuous medication group had more significant improvements in SCORAD, EASI, NRS, and ADCT scores at 52 weeks than the noncontinuous medication group (p < 0.05). The 6-month and 1-year drug survival rates of dupilumab were 59.7% and 51.9%, respectively. The most common reason for treatment discontinuation was the satisfactory control of AD. Patients with adult-onset AD (adjusted odds ratio [OR]: 0.15, 95% confidence interval [CI]: 0.03-0.73) , not complicated by other systemic diseases (adjusted OR: 0.17, 95% CI: 0.04-0.84) and eosinophilia at baseline (adjusted OR: 3.71, 95% CI: 1.12-12.26) had a higher probability of drug discontinuation. In real-world practice in China, dupilumab has exhibited good long-term effectiveness and safety for the treatment of moderate-to-severe AD, and continuous administration can benefit patients in the long term.
