Diagnosis of Allergic Dermatoses in Skin of Color.

PURPOSE OF REVIEW: This review aims to deliver a comprehensive report of the most recent knowledge on diagnosing allergic dermatoses in skin of color (SOC) patients. RECENT FINDINGS: Allergic dermatoses can affect populations of all backgrounds. However, racial/ethnic variations in epidemiology, clinical features, and associated allergens have been reported. Nuances in the approach to diagnosis, including the assessment of erythema and interpretation of patch tests, are important considerations when treating patients with SOC. In this review, we outline various manifestations of allergic dermatoses in SOC with a focus on important clinical presentations and diagnostic tools, aiming to support clinicians in accurate recognition of diseases, thereby opening avenues to improve outcomes across diverse skin types.

A Practical Algorithm for Integrating Skincare to Improve Patient Outcomes and Satisfaction With Energy-Based Dermatologic Procedures.

BACKGROUND: Medical aesthetic procedures for facial antiaging with laser and energy-based devices (EBDs) are rapidly increasing, but standards integrating skincare before, during, and after these treatments are lacking. The algorithm for integrated skin care for facial antiaging treatment with EBDs aims to stimulate healing, reduce downtime, and improve comfort and treatment outcomes. METHODS: A panel of 8 global physicians employed a modified Delphi method and reached a consensus on the algorithm integrating skincare based on the best available evidence, the panel's clinical experience, and opinions. RESULTS: The algorithm has a pretreatment (starts 2 - 4 weeks before the procedure) and treatment (day of treatment) section, followed by care after the procedure (0 - 7 days) and follow-up care (1 - 4 weeks after the procedure or ongoing). Applying a broad-spectrum sunscreen with an SPF 50 or higher, combined with protective measures such as wearing a wide-brimmed hat and sunglasses, is recommended to protect the face from sun exposure. Dyschromia is a significant concern for those with skin of color (SOC). Clinicians may recommend skincare using a gentle cleanser and moisturizer containing vitamins C and E, retinoid, or other ingredients such as niacinamide, kojic acid, licorice root extract, azelaic acid, and tranexamic acid, depending on the patient's facial skin condition. CONCLUSION: Medical aesthetic procedures for facial antiaging with EBDs integrating skincare or topical treatments may improve outcomes and patient satisfaction. Topical antioxidants and free radical quenchers can combat photodamage and may offer a safe alternative to topical hydroquinone.  J Drugs Dermatol. 2024;23(5):353-359.     doi:10.36849/JDD.8092.

Importance of treating acne sequelae in skin of color: 6-month phase IV study of trifarotene with an appropriate skincare routine including UV protection in acne-induced post-inflammatory hyperpigmentation.

BACKGROUND: Acne-induced hyperpigmentation (AIH) may accompany acne vulgaris (AV) inflammation in all skin phototypes. Trifarotene has shown depigmenting properties in vivo. This study evaluated trifarotene plus skincare because it is increasingly recognized that holistic AV management should include skincare and treatments. METHODS: This is a phase IV double-blind, parallel-group study of patients (13-35 years) with moderate AV and AIH treated with trifarotene (N = 60) or vehicle (N = 63) plus skincare regimen (moisturizer, cleanser, and sunscreen) for 24 weeks. Assessments included the AIH overall disease severity (ODS) score, post-AV hyperpigmentation index (PAHPI), exit interviews, photography, and acne assessments. Standard safety assessments were included. RESULTS: Trifarotene 50 µg/g cream improved significantly from baseline in ODS score versus vehicle (-1.6 vs. -1.1, P = 0.03) at Week 12, but scores were comparable between groups at Week 24 (primary endpoint). Trifarotene had a better reduction in PAHPI score at Week 24 (-18.9% vs. -11.3% vehicle, P < 0.01). Lesion count reductions were higher with trifarotene at Week 12 versus vehicle (P < 0.001) and at Week 24 (P < 0.05), as were IGA success rates versus vehicle at Weeks 12 (P < 0.05) and 24 (P < 0.05). Patients agreed that the skincare regimen contributed to less irritation, making treatment adherence easier. Photography showed improvements in pigmentation and erythema across all skin types. AEs were more common in the vehicle group versus trifarotene (30.2 vs. 16.7%, respectively). CONCLUSIONS: In all skin phototypes, there was more rapid improvement in the ODS and PAHPI scores with trifarotene by Weeks 12 and 24, respectively. The combination of trifarotene and skincare correlated with high patient satisfaction and adherence to the treatment protocol.

Deucravacitinib in moderate-to-severe plaque psoriasis: Pooled safety and tolerability over 52 weeks from two phase 3 trials (POETYK PSO-1 and PSO-2).

BACKGROUND: Two phase 3 trials, POETYK PSO-1 and PSO-2, previously established the efficacy and overall safety of deucravacitinib, an oral, selective, allosteric tyrosine kinase 2 (TYK2) inhibitor, in plaque psoriasis. OBJECTIVES: To further assess the safety of deucravacitinib over 52 weeks in the pooled population from these two trials. METHODS: Pooled safety data were evaluated from PSO-1 and PSO-2 in which patients with moderate-to-severe plaque psoriasis were randomized 1:2:1 to receive oral placebo, deucravacitinib or apremilast. RESULTS: A total of 1683 patients were included in the pooled analysis. Adverse event (AE) incidence rates were similar in each treatment group, serious AEs were low and balanced across groups, and discontinuation rates were lower with deucravacitinib versus placebo or apremilast. No new safety signals emerged with longer deucravacitinib treatment. Exposure-adjusted incidence rates of AEs of interest with placebo, deucravacitinib and apremilast, respectively, were as follows: serious infections (0.8/100 person-years [PY], 1.7/100 PY, and 1.8/100 PY), major adverse cardiovascular events (1.2/100 PY, 0.3/100 PY, and 0.9/100 PY), venous thromboembolic events (0, 0.2/100 PY, and 0), malignancies (0, 1.0/100 PY and 0.9/100 PY), herpes zoster (0.4/100 PY, 0.8/100 PY, and 0), acne (0.4/100 PY, 2.9/100 PY, and 0) and folliculitis (0, 2.8/100 PY, and 0.9/100 PY). No clinically meaningful changes from baseline in mean levels, or shifts from baseline to CTCAE grade ≥3 abnormalities, were reported in laboratory parameters with deucravacitinib. CONCLUSIONS: Deucravacitinib was well-tolerated with acceptable safety over 52 weeks in patients with psoriasis.

Is it too early to recommend local treatment in oligometastatic non-small cell lung cancer: a plea for equipoise.

Oligometastatic non-small cell lung cancer (OMD NSCLC) has been proposed to bridge the spectrum between non-metastatic and widely metastatic states and is perceived as an opportunity for potential cure if removed. Twelve clinical trials on local treatment have been reported, yet none are conclusive. These trials informed the development of a joint clinical practice guideline by the American & European Societies for Radiation Oncology, which endorses local treatment for OMD NSCLC. However, the heterogeneity between prognostic factors within these trials likely influenced outcomes and can only support guidance at this time. Caution against an uncritical acceptance of the guideline is discussed, as strong recommendations are offered based on expert opinion and inconclusive evidence. The guideline is also examined by a patient's caregiver, who emphasizes that uncertain evidence impedes shared decision making.

Integrating skin color assessments into clinical practice and research: A review of current approaches.

Skin color classification can have importance in skin health, pigmentary disorders, and oncologic condition assessments. It is also critical for evaluating disease course and response to a variety of therapeutic interventions and aids in accurate classification of participants in clinical research studies. A panel of dermatologists conducted a literature review to assess the strengths and limitations of existing classification scales, as well as to compare their preferences and utilities. We identified 17 skin classification systems utilized in dermatologic settings. These systems include a range of parameters such as UV light reactivity, race, ethnicity, and degree of pigmentation. The Fitzpatrick skin type classification is most widely used and validated. However it has numerous limitations including its conflation with race, ethnicity, and skin color. There is a lack of validation data available for the remaining scales. There are significant deficiencies in current skin classification instruments. Consensus-based initiatives to drive the development of validated and reliable tools are critically needed.

Outcomes for Psoriasis by Self-Identified Racial Groups in Ixekizumab Clinical Trials: A Pooled Analysis.

BACKGROUND: Biologics have shown promising outcomes in psoriasis clinical trials. However, there is a paucity of data exploring the potential differences in outcomes between self-identified racial groups. OBJECTIVE: To evaluate treatment response to ixekizumab in patients with psoriasis across different self-identified racial subgroups. METHODS: This study analyzed pooled data from 5 clinical studies (UNCOVER-1, UNCOVER-2, UNCOVER-3, IXORA-R, and IXORA-S) with patients of different self-identified racial subgroups, who were treated with an on-label dose of ixekizumab for psoriasis through 12 weeks. Treatment response to ixekizumab was assessed using the Psoriasis Area and Severity Index (PASI) and static Physician’s Global Assessment response rates. Patient Global Assessment of Disease Severity, Itch Numeric Rating Scale, Skin Pain Visual Analog Scale, and Dermatology Life Quality Index were used to evaluate the patient-reported outcomes (PROs) and impact on quality of life (QoL). RESULTS: A total of 1825 ixekizumab-treated patients from 5 pooled studies were included. Consistent with the clinical outcomes from the overall population, all self-identified racial groups showed rapid improvement in PASI through Week 12, although the response was somewhat slower in American Indian/Alaska Native patients. Differences in PROs and QoL assessments were observed among racial groups, especially in patients who identified as Black/African American and American Indian/Alaska Native. CONCLUSION: Ixekizumab is effective through 12 weeks of treatment for psoriasis across different self-identified racial groups. Sample sizes for some racial groups were small (N≤12), therefore, further research is required to understand potential differences in psoriasis treatment with ixekizumab between various racial groups.J Drugs Dermatol. 2024;23(2):17-22.  doi:10.36849/JDD.7672.

INDIVIDUAL ARTICLE: Impact of Acne Vulgaris and Sarecycline on Social/Emotional Functioning and Daily Activities: PROSES Study.

BACKGROUND: Concise patient-reported outcome (PRO) instruments addressing the consequences of facial acne vulgaris (AV) on patients’ functioning and activities of daily living (ADL) are needed. METHODS: A 12-week, single-arm, prospective cohort study was conducted in patients ≥9 years old with moderate/severe non-nodular facial AV prescribed sarecycline as part of usual care. The primary endpoint included AV-specific patient- and caregiver-reported outcomes assessed with the expert panel questionnaire (EPQ, developed by 10 experts using a Delphi method) in patients (>12 years) and caregivers (for patients 9-11 years). Additional assessments included parental/caregiver perspectives on children’s AV. RESULTS: A total of 253 patients completed the study. Following 12-weeks of treatment, there were significant (P ≤.0001) changes from baseline in the proportion of patients responding that they never or rarely: felt angry (31.6%), worried about AV worsening (28.9%), had thoughts about AV (20.9%), had a certain level of worries about AV (38.7%), altered their social media/selfie activity (23.7%), had an impact on real-life plans due to AV (22.9%), made efforts to hide AV (21.3%), felt picked-on/judged due to AV (15.0%), were concerned about their ability to reach future goals due to AV (13.8%), or had sleep impacted due to AV (18.2%). No significant change from baseline was observed for parent/caregiver’s understanding of the child’s AV concerns, from both patient and parent/caregiver perspectives. CONCLUSIONS: Over 12 weeks of AV management with oral sarecycline, patients reported significant reductions in AV-related effects on emotional/social functioning and ADL as measured by the EPQ, a simple PRO with potential for use in clinical practice.

INDIVIDUAL ARTICLE: Sarecycline Improves Acne Severity, Symptoms, and Psychosocial Burden in Non-nodular Acne Vulgaris: PROSES Study.

BACKGROUND: Patient-reported outcomes (PROs) are emerging as a fundamental component of disease impact assessment in acne vulgaris (AV), complementing clinician-reported outcomes. No data is available on PROs for patients with AV using sarecycline in real-world settings. METHODS: A single-arm, prospective cohort study that included patients ≥9 years old diagnosed with moderate or severe non-nodular AV was implemented as part of routine care in clinical practices (N=30). Patients received oral sarecycline (60 mg, 100 mg, or 150 mg) for 12 weeks, as part of usual care. The primary endpoint was Acne Symptom and Impact Scale (ASIS) responses from patients (≥12 years) and caregivers (for patients 9-11 years) at week 12 and change from baseline (CFB). Investigator’s Global Assessment (IGA) of AV severity and adverse events (AEs) were also recorded. RESULTS: A total of 253 patients with AV completed the study (adults: 60.1%, females: 77.6%). ASIS mean scores significantly decreased (P <.0001) at week 12 for: signs (mean CFB ± standard deviation [SD]: –0.8 ± 0.7), impact (–1.0 ± 1.0), emotional impact (–1.2 ± 1.1), and social impact (0.6 ± 1.1). Significant reductions in AV severity (P <.0001) were reported by patients and caregivers. The IGA success rate was 58.9% and physician satisfaction with treatment outcomes was 88.1%. A total of 31 (10.3%) patients reported ≥1 AE during the study. CONCLUSIONS: Patients with moderate-to-severe AV receiving acne management with an oral antibiotic for 12 weeks experienced a significant improvement in AV-related symptoms and psychosocial burden.

Best practices in the treatment of melasma with a focus on patients with skin of color.

BACKGROUND: Melasma is a chronic hypermelanosis of the skin that affects approximately 1% of the global population, predominantly affects women, and is more prevalent in skin of color. Melasma is a common driver for patients with skin of color to seek out a dermatologist for treatment, and ensuring the right approach for these patients is important because some treatments may be associated with adverse side effects. Because of the chronicity of the disease and established psychosocial and emotional impacts, there is a large need to ensure care follows the best available evidence on the treatment of patients with melasma. OBJECTIVE: Here, we summarized current available topical treatments for melasma with considerations dermatologists should have for their patients with skin of color. METHODS: Steering committee consensus on clinical best practices. RESULTS: We describe a flexible and focused treatment algorithm that reflects both treatment and maintenance periods that is a consensus of our extensive clinical experience. LIMITATIONS: Use of real-world evidence and potential for individual practice bias. CONCLUSION: Melasma can be challenging to treat, particularly in patients with skin of color, and our recommendations for best practices for patients in the United States are an important step toward standardizing care.

Abrocitinib efficacy and safety in moderate-to-severe atopic dermatitis by race, ethnicity, and Fitzpatrick skin type.

BACKGROUND: Response to abrocitinib treatment for moderate-to-severe atopic dermatitis (AD) has not been evaluated across racial and ethnic subpopulations. OBJECTIVE: To assess the efficacy and safety of abrocitinib on the basis of patient race, ethnicity, and Fitzpatrick skin type (FST). METHODS: Data were pooled post hoc from patients treated with abrocitinib 200 mg, 100 mg, or placebo in 3 monotherapy trials (NCT02780167, NCT03349060, and NCT03575871). Race and ethnicity were self-reported; FST was determined by study investigators. Evaluations through Week 12 include the following: (1) Investigator's Global Assessment of clear or almost-clear skin; (2) greater than or equal to 75% improvement in Eczema Area and Severity Index or SCORing AD; (3) a greater-than-or-equal-to 4-point improvement in Peak Pruritus Numerical Rating Scale score; (4) least squares mean changes in Dermatology Life Quality Index and Patient-Oriented Eczema Measure scores; and (5) treatment-emergent adverse events. RESULTS: The sample comprised 628 White, 204 Asian, and 83 Black patients; 37 were Hispanic or Latino; 624 had FST I to III and 320 had FST IV to VI. Treatment with either abrocitinib dose was associated with greater proportions of patients achieving Investigator's Global Assessment of clear or almost-clear skin, ≥ 75% improvement in Eczema Area and Severity Index, ≥ 75% improvement in SCORing AD, and a ≥ 4-point improvement in Peak Pruritus Numerical Rating Scale, or greater score changes from baseline in Dermatology Life Quality Index and Patient-Oriented Eczema Measure vs placebo regardless of race, ethnicity, or FST. Dose-response was most prominent in White patients. In Black patients, the effects of the 2 doses were similar. Treatment-emergent adverse events were more common in White and Black than in Asian patients. CONCLUSION: Abrocitinib was more efficacious than placebo across the racial and ethnic groups and ranges of phototypes analyzed. Studies with increased representation of populations of color are warranted to elucidate potential variations in response across diverse populations. TRIAL REGISTRATION: Clinicaltrials.gov Identifier: NCT02780167 (phase 2b), NCT03349060 (phase 3 MONO-1), and NCT03575871 (phase 3 MONO-2).

Development of an Eczema Area and Severity Index Atlas for Diverse Skin Types.

Background: Current guidance for using Eczema Area and Severity Index (EASI) implementation is limited to lighter skin phototypes. We developed an EASI lesion severity atlas and refined guidance for investigators and clinicians to use across diverse patient populations. Methods: A review was performed of clinical images from internal atopic dermatitis (AD) photorepositories. Representative images of the 4 AD signs included in EASI were selected for different physician-assessed skin phototypes. Images were excluded if they had low resolution, poor focus, or lighting. Discrepancies regarding skin pigmentation and AD severity were resolved by consensus between authors. Results: Over 3000 clinical photographs were reviewed. Final images were selected using an iterative review process and consensus. Two different versions of the atlas were created across 6 physician-assessed phototypes (I-VI) and 3 skin complexions (light, medium, and dark). We propose guidance language for erythema to reflect the range of colors encountered across different skin complexions (shades of red, purple, and brown). Conclusion: We created a photographic atlas and updated guidance language for implementing EASI in diverse populations, including those with higher skin phototypes.

Influence of Season on Efficacy and Tolerability of Tazarotene 0.045% Lotion for the Treatment of Acne.

Objective: The condition of the skin can vary due to weather fluctuations. Therefore, this post-hoc analysis evaluated efficacy and safety of tazarotene 0.045% lotion in warmer versus colder months. Methods: In two Phase III, double-blind, 12-week studies, participants aged nine years or older with moderate-to-severe acne were randomized 1:1 to once-daily tazarotene or vehicle lotion. The pooled population (N=1,614) was stratified by randomization date (warmer=May to September; colder=October to April). Evaluations included inflammatory/noninflammatory lesion counts, treatment success, adverse events, and safety/tolerability. Results: Tazarotene 0.045% lotion was similarly efficacious over colder and warmer months. Compared with vehicle, tazarotene demonstrated significantly greater least-squares mean absolute reductions from baseline to Week 12 in inflammatory (colder/warmer tazarotene vs. vehicle: -16.6/-15.8 vs. -13.2/-12.9) and noninflammatory lesions (-23.2/-22.6 vs. -17.5/-15.1); treatment success rates were also significantly higher (30.1/30.8% vs. 18.2/17.6%) (P<0.001, all). No strong seasonal trends in safety were observed, though tazarotene led to slightly more discontinuations (3.4% vs. 1.9%) and related adverse events (12.0% vs. 10.3%) in colder versus warmer months. Transient increases in scaling, erythema, and itching at Weeks 2 to 8 of tazarotene treatment were slightly higher in colder versus warmer months but returned to baseline/improved by Week 12. Limitations: Geographical variation across study sites can lead to varying temperatures and humidity within the same months. Conclusion: Tazarotene 0.045% lotion was efficacious and well tolerated for acne treatment, regardless of season. Year-round tolerability of tazarotene 0.045% lotion may be due to its lower tazarotene concentration and polymeric emulsion technology, which simultaneously delivers moisturizers/humectants/emollients to skin.

Insights into acne and the skin barrier: Optimizing treatment regimens with ceramide-containing skincare.

INTRODUCTION: Acne is a common, complex, multifactorial inflammatory skin disease associated with epidermal barrier dysfunction. Beginning in childhood, acne affects many adolescents and adults. Acne is associated with lower self-esteem, anxiety, and depression and may cause scars and pigmentary sequelae. The review explores the relationships between acne and the skin barrier function and discusses nuances in the prevention, treatment, and maintenance of acne and its impact on the skin barrier. METHODS: The advisors' previous publications addressed prescription and nonprescription pediatric acne treatment and skincare using cleansers, moisturizers, and a practical algorithm for treatment and maintenance, including skincare recommendations for pediatric acne patients and an algorithm for skin of color patients with acne. Before the meeting, literature was culled on the relationship between the skin barrier and acne and current best practices in acne, addressing prescription and nonprescription acne products and skincare as monotherapy, adjunctive, and maintenance treatment. RESULTS: After discussing 13 draft statements, the advisors applied the selected literature and drew from their clinical knowledge and experience, and agreed on five statements. The follicular epithelial barrier is directly involved with changes that occur during both comedogenesis and in stages of inflammation, especially with follicular rupture compromising the barrier's integrity. In acne-affected skin, sebaceous glands are larger, sebum excretion and filaggrin expression higher, and stratum corneum lipids are reduced. Educating patients and clinicians about inflammation's central role in acne and measures to reduce inflammation is essential. Skin irritation and xerosis from acne and treatments lead to poor treatment adherence. A skincare regimen should be included in the acne prevention, treatment, and maintenance care regimen and should be ongoing. Maintenance treatment with topical agents and skincare using gentle ceramide-containing cleansers and moisturizers is a recommended strategy after successfully controlling the disease. CONCLUSIONS: Epidermal barrier dysfunction contributes to acne exacerbation. Using the appropriate treatment and skincare helps to minimize irritation and inflammation, enhance treatment adherence, and improve patient outcomes.

Psoriasis and Skin Barrier Dysfunction: The Role of Gentle Cleansers and Moisturizers in Treating Psoriasis.

BACKGROUND: Psoriasis is a chronic immune-mediated dermatologic disorder with multisystemic comorbidities, which is effectively treated with a range of prescription therapies. Studies have reported epidermal barrier abnormalities in the lesional skin of psoriasis patients; however, there is currently insufficient information about skin barrier function in psoriasis patients. This review discusses the potential role of gentle cleansers and moisturizers in the management of psoriasis and in promoting a healthy skin barrier. METHODS: A literature review was followed by the authors' discussions and agreement on 5 statements to provide expert guidance for gentle cleansers and moisturizer use in psoriasis patients. RESULTS: In a workshop, the authors provided feedback on 15 draft statements created prior to the meeting, and agreed upon 5 statements. The authors agreed that guidelines rarely mention skincare for psoriasis patients, demonstrating a potential knowledge gap. Skincare may play a role in managing psoriasis as an adjuvant treatment of acute psoriasis and for maintenance treatment of healing skin during asymptomatic periods. Studies of patients with psoriasis applying topical moisturizers (such as those containing salicylic acid or ceramides) showed softened plaques, enhancing the absorption of topical treatments such as corticosteroids. Studies applying ceramide-containing skincare showed an overall improvement in the appearance of the skin and provided relief for psoriasis. CONCLUSION: The authors agreed that skincare and barrier restoration in treating psoriasis is a relatively new concept for most dermatologists. There is a need to develop a more robust body of evidence on skincare for psoriasis to influence clinical practice in a meaningful way. Kircik L, Alexis AF, Andriessen A, et al.

INDIVIDUAL ARTICLE: An Algorithm for the Management of Atopic Dermatitis in People With Skin of Color.

BACKGROUND: Variations in the epidemiology, clinical presentation, and disease course in skin of color (SOC) atopic dermatitis (AD) patients have been reported that may impact treatment approach and skincare recommendations. METHODS: The project used a modified Delphi hybrid process comprising face-to-face discussions and an online review process. A panel of physicians (advisors) who treat SOC patients with AD used information from literature searches, expert opinions, and their experience to develop a practical algorithm to improve outcomes for SOC patients with AD. RESULTS: The algorithm for SOC patients with AD aims to inform dermatologists and other healthcare professionals caring for these patients. The first section of the algorithm addresses education and behavioral measures. Treatment adherence is a considerable challenge in chronic inflammatory conditions such as AD, making education essential. The second section discusses the assessment of the skin condition. The third section informs on treatment and maintenance measures for AD. Treatment and maintenance of AD in patients with SOC should be proactive, effectively control inflammation longitudinally, include effective skin barrier protective strategies, and consider cultural practices. CONCLUSION: Robust comparative studies are needed to better understand racial/ethnic variations in AD. The algorithm supports educating healthcare professionals and patients to foster individualized treatment, prevention, and adjunctive skincare approaches across diverse patient populations.

Racial and Ethnic Differences in Sociodemographic, Clinical, and Treatment Characteristics Among Patients with Atopic Dermatitis in the United States and Canada: Real-World Data from the CorEvitas Atopic Dermatitis Registry.

INTRODUCTION: This real-world, cross-sectional study compared sociodemographic, clinical and treatment characteristics, and patient-reported outcomes (PROs) among racial/ethnic groups in patients with atopic dermatitis (AD) who are candidates for systemic therapy. METHODS: This study included adults with dermatologist- or dermatology practitioner-diagnosed AD enrolled in the CorEvitas AD Registry (July 2020-July 2021). All patients initiated systemic therapy within 12 months prior to or at enrollment or had moderate-to-severe AD (vIGA-AD® ≥ 3 and Eczema Area and Severity Index [EASI] ≥ 12) at enrollment. Patients were categorized into five mutually exclusive racial/ethnic groups: non-Hispanic White, Black, Asian, Other/Multiracial, and Hispanic (any race). Patient, clinical, and treatment characteristics were captured at enrollment. Differences in means or proportions of characteristics among racial/ethnic groups were descriptively summarized using effect sizes. Adjusted prevalence ratios and mean differences were estimated (White race/ethnicity group as the reference category) with 95% confidence intervals (CI). RESULTS: Among 1288 patients, 64% (n = 822) were White, 13% (n = 167) Black, 10% (n = 129) Asian, 8% (n = 97) Hispanic, and 6% (n = 73) Other/Multiracial. In adjusted analyses, statistically more severe EASI lichenification was noted among Black compared with White patients at the head and neck (mean difference, 0.21, [95% CI 0.06, 0.36]; p = 0.01), trunk (0.32, [0.17, 0.47]; p < 0.001), upper extremities (0.27, [0.09, 0.44]; p = 0.008), and lower extremities (0.39, [0.21, 0.57]; p < 0.001). Statistically more severe EASI lichenification was observed among Asian vs White patients in certain areas (mean difference, head and neck, 0.22 [0.04, 0.39], p = 0.01; trunk, 0.25 [0.07, 0.43], p < 0.001; lower extremities, 0.22 [0.01, 0.43], p < 0.001) and SCORing for AD lichenification (mean difference: 0.34 [0.15, 0.52]; p < 0.001). Significantly higher mean pruritus over the past 7 days for Black (mean difference: 0.63 [0.01, 1.26] and Hispanic patients (0.60 [0.11, 1.09]; p = 0.03) vs White patients was observed. Among AD clinical features, the prevalence of facial erythema was significantly lower among Black compared with White patients (prevalence ratio = 0.38, [0.22, 0.67]; p = 0.007). CONCLUSION: Racial/ethnic differences exist in sociodemographic, clinical and treatment characteristics, disease severity, and PROs among real-world AD patients who are candidates for systemic therapy. Recognizing these variations may be of critical importance for dermatologists for the design and delivery of targeted/personalized medicine approaches.

The Personalized Acne Treatment Tool - Recommendations to facilitate a patient-centered approach to acne management from the Personalizing Acne: Consensus of Experts.

Background: Acne, a commonly treated skin disease, requires patient-centered management due to its varying presentations, chronicity, and impact on health-related quality of life. Despite this, evidence-based clinical guidelines focus primarily on clinical severity of facial acne, omitting important patient- and disease-related factors, including ongoing management. Objectives: To generate recommendations to support patient-centered acne management, which incorporate priority and prognostic factors beyond conventional clinical severity, traditionally defined by grading the appearance and extent of visible lesions. Methods: The Personalizing Acne: Consensus of Experts consisted of 17 dermatologists who used a modified Delphi approach to reach consensus on statements regarding patient- and treatment-related factors pertaining to patient-centered acne management. Consensus was defined as ≥75% voting "agree" or "strongly agree." Results: Recommendations based on factors such as acne sequelae, location of acne, high burden of disease, and individual patient features were generated and incorporated into the Personalized Acne Treatment Tool. Limitations: Recommendations are based on expert opinion, which may differ from patients' perspectives. Regional variations in healthcare systems may not be represented. Conclusions: The Personalizing Acne: Consensus of Experts panel provided practical recommendations to facilitate individualized management of acne, based on patient features, which can be implemented to improve treatment outcomes, adherence, and patient satisfaction.
