RESUMO
Seborrheic dermatitis (SD) is a highly prevalent dermatological condition globally. The condition demonstrates bimodal presentation with what is commonly thought to be two subtypes: adult/adolescent seborrheic dermatitis (ASD) and infantile seborrheic dermatitis (ISD). Despite the common prevalence of ASD and ISD, there remains uncertainty around the underlying pathogenetic mechanisms, risk factors, and appropriate classification of the disease(s). This narrative review summarizes the current understanding of the epidemiology, presentation, and pathogenetic factors like epidermal barrier dysfunction, lipid abnormalities, and cutaneous microbiome for ASD and ISD. Elements such as immune responsiveness, neuroendocrine factors, and genetics in these disease states are also investigated. Throughout our review, we highlight shared features and discrepancies between ASD and ISD that are present in the literature and discuss potential avenues for future research that explore these disease states. We aim to contribute to the medical discourse on ASD and ISD and increase awareness of the need for additional research around these conditions, ultimately informing better targeting of therapeutics moving forward.
RESUMO
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.

Purpose: Ruxolitinib (selective Janus kinase [JAK] 1 and JAK2 inhibitor) cream demonstrated efficacy and safety in patients with atopic dermatitis (AD) in the phase 3 TRuE-AD studies. In TRuE-AD1/TRuE-AD2 (NCT03745638/NCT03745651), adults and adolescents with mild to moderate AD were randomized to apply twice-daily ruxolitinib cream or vehicle for eight weeks. Here, we evaluated the efficacy and tolerability of ruxolitinib cream by anatomic region, focusing on head/neck (HN) lesions that are typically difficult to manage and disproportionately affect quality of life (QoL).Materials and methods: Eczema Area and Severity Index (EASI) responses in anatomic regions were evaluated in the pooled population (N = 1208) and among patients with baseline HN involvement (n = 663). Itch, Investigator's Global Assessment (IGA), QoL, and application site tolerability were also assessed.Results: By Week 2 (earliest assessment), ruxolitinib cream application resulted in significant improvements across all EASI anatomic region subscores and AD signs versus vehicle, with further improvements through Week 8. Significantly more patients with HN involvement who applied ruxolitinib cream versus vehicle achieved clinically meaningful improvements in itch, IGA, and QoL. Application site reactions with ruxolitinib cream were infrequent (<3%), including in patients with HN involvement.Conclusions: These results support the use of ruxolitinib cream for AD treatment across all anatomic regions, including HN.

BACKGROUND: Atopic dermatitis (AD) is thought to precede the onset of other allergic illness (OAI) in a temporal progression (ie, atopic march), yet the timing and progression has been questioned. It is also unclear how parental allergic illness impacts the development of these illnesses in offspring. OBJECTIVE: (1) Explore risk of incident AD and (2) timing of allergic disease onset in children of mothers with AD compared with mothers without AD from the United Kingdom. METHODS: We created a birth cohort of mother-child pairs using IQVIA Medical Research Data database and developed Cox proportional models to examine the above associations (hazard ratio, HR [95% confidence interval, CI]). RESULTS: Among 1,224,243 child-mother pairs, mean child (standard deviation) follow-up time was 10.8 (8.3) years and 50.1% were males (N = 600,905). Children were 59% (HR = 1.59 [1.57, 1.60]) more likely to have AD if their mothers had AD compared with no AD with mean age of first AD diagnosis at 3.3 (4.8) years. Most children with any diagnosis of AD present with AD first (91.0%); however, in those with asthma, only 67.8% developed AD first. CONCLUSION: Children born to mothers with AD are more prone to develop AD and some develop OAI first, suggesting that not all follow the same sequential pathway.

Importance: Data on the association between atopic dermatitis (AD) and inflammatory bowel disease (IBD) are inconsistent. Few studies have examined the association of AD or AD severity with risk of ulcerative colitis (UC) and Crohn disease (CD) separately. Objectives: To examine the risk of new-onset IBD, UC, and CD in children and adults with AD. Design, Setting, and Participants: This population-based cohort study assessed patients with AD matched with up to 5 controls on age, practice, and index date. Treatment exposure was used as a proxy for AD severity. Data were retrieved from The Health Improvement Network, a UK electronic medical record database, for January 1, 1994, to February 28, 2015. Data analysis was performed from January 8, 2020, to June 30, 2023. Main Outcomes and Measures: Outcomes of interest were incident IBD, UC, and CD. Logistic regression was used to examine the risk for each outcome in children and adults with AD compared with controls. Results: A total of 1â¯809â¯029 pediatric controls were matched to 409â¯431 children with AD (93.2% mild, 5.5% moderate, and 1.3% severe). The pediatric cohort ranged in median age from 4 to 5 years (overall range, 1-10 years), was predominantly male (936â¯750 [51.8%] controls, 196â¯996 [51.6%] with mild AD, 11â¯379 [50.7%] with moderate AD, and 2985 [56.1%] with severe AD), and with similar socioeconomic status. A total of 2â¯678â¯888 adult controls were matched to 625â¯083 adults with AD (65.7% mild, 31.4% moderate, and 2.9% severe). The adult cohort ranged in median age from 45 to 50 years (overall range, 30-68 years) and was predominantly female (1â¯445â¯589 [54.0%] controls, 256â¯071 [62.3%] with mild AD, 109â¯404 [55.8%] with moderate AD, and 10â¯736 [59.3%] with severe AD). In fully adjusted models, children with AD had a 44% increased risk of IBD (hazard ratio [HR], 1.44; 95% CI, 1.31-1.58) and a 74% increased risk of CD (HR, 1.74; 95% CI, 1.54-1.97), which increased with worsening AD; however, they did not have increased risk of UC (HR, 1.09; 95% CI, 0.94-1.27) except for those with severe AD (HR, 1.65; 95% CI, 1.02-2.67). Adults with AD had a 34% (HR, 1.34; 95% CI, 1.27-1.40) increased risk of IBD, a 36% (HR, 1.36; 95% CI, 1.26-1.47) increased risk of CB, and a 32% (HR, 1.32; 95% CI, 1.24-1.41) increased risk of UC, with risk increasing with worsening AD. Conclusion and Relevance: In this cohort study, children and adults with AD had an increased risk of IBD, with risk varying by age, AD severity, and IBD subtype. These findings provide new insights into the association between AD and IBD. Clinicians should be aware of these risks, particularly when selecting systemic treatments for AD in patients who may have coincident gastrointestinal symptoms.

To address the need for long-term efficacy and patient-reported outcomes (PROs) data for patients with atopic dermatitis (AD) treated with baricitinib 2 mg, a study was conducted to evaluate the efficacy of baricitinib 2 mg in adult patients with moderate-to-severe AD. Data presented here provided efficacy and outcomes data for patients treated for 52 weeks. Patients who participated in the originating study, BREEZE-AD5 (NCT03435081), and met additional eligibility criteria could enroll in the multicenter, open-label, Phase 3, long-term extension study BREEZE-AD6 (NCT03559270). Patients received baricitinib 2 mg for the duration of BREEZE-AD6. In BREEZE-AD6, the proportion of patients who achieved a 75% improvement in the Eczema Area and Severity Index (EASI75) and validated Investigator Global Assessment for AD (vIGA-AD™) of 0 (clear) or 1 (almost clear) were assessed through 52 weeks, in addition to several PROs. At week 52, the proportion of patients treated with baricitinib 2 mg daily achieving EASI75 was 48.6% (70/144), and 31.3% (45/144) of patients achieved a vIGA-AD score of 0 or 1 (clear or almost clear). Improvements in PROs such as SCORing Atopic Dermatitis (SCORAD, itch and sleep) scores, Dermatology Life Quality Index (DLQI) total score, and DLQI ≤5 response were observed, and these responses were sustained through 52 weeks. Long-term efficacy of baricitinib in patients with AD was demonstrated by both clinician and patient-reported outcome measures.

Terrestrial sunlight is the portion of electromagnetic radiation that is emitted by the sun and reaches Earth's surface. It encompasses 3 major components: UV radiation (290-400 nm), visible light (400-700 nm), and infrared radiation. The deleterious effects of UV radiation have been appreciated for decades, particularly among those with light skin tones (Fitzpatrick skin types I-II) who primarily manifest with burns of varying degrees of severity with sun exposure. In recent years, studies have increasingly shown the negative impact of visible light on skin health, particularly in individuals with skin of color (Fitzpatrick skin types IV-VI), including the exacerbation of hyperpigmentation disorders such as melasma and post-inflammatory hyperpigmentation, as well as induction of the former. Recommendations from medical societies and the US Food and Drug Administration for photoprotection have been evolving along with the knowledge base. Yet, misconceptions about skin damage related to sunlight and the benefits of photoprotection (particularly among those with Fitzpatrick skin types V-VI) are still prevalent among both clinicians and patients. Among patients with skin of color, disorders of hyperpigmentation and other consequences from sun exposure have been associated with impaired skin health and negative burden on quality of life. This review summarizes currently available evidence of the impact of both UV and visible wavelengths and the low utilization of photoprotection measures among people with skin of color, with the goal of providing recommendations to help educate patients.

The negative effects of sun exposure have become better accepted among health care professionals and the lay public over recent decades. Most attention has been focused on the effects of UV light, particularly UVB wavelengths (290-320 nm). Accordingly, products to protect skin from sunlight-associated harm (sunscreens) have been developed to minimize UVB exposure. The effects of longer wavelengths, including UVA (320-400 nm) and visible light (VL, 400-700 nm), are increasingly appreciated. VL accounts for approximately half of the solar radiation that reaches the earth's surface and understanding of its effects on the skin is improving. Studies have shown that VL can induce hyperpigmentation in individuals with dark skin types (Fitzpatrick skin types IV-VI). In addition, VL can contribute to the exacerbation of pigmentary disorders, including melasma. Because these findings are relatively new, there are gaps in understanding the needs for photoprotection and guidance for clinicians. A panel of dermatologists and photobiologists was convened to develop consensus recommendations and clinical guidance about sunscreen use relevant to the current understanding of risks associated with sun exposure using a modified Delphi method.

PURPOSE: "Not relevant" responses (NRRs) on the Dermatology Life Quality Index (DLQI) are common among adults with psoriasis and may be associated with underestimation of disease burden. Little is known about "not relevant" responses among adults with atopic dermatitis. We aimed to examine the frequency of NRRs on the DLQI and to determine whether NRRs are associated with underestimation of disease burden among adults with atopic dermatitis. METHODS: Adults with atopic dermatitis were identified and evaluated via online survey. We evaluated the frequency of NRRs on the DLQI, stratified by sociodemographic characteristics. To examine the association between NRRs and other measures of disease burden, Patient-Oriented Eczema Measure (POEM), Patient-Oriented SCORAD (PO-SCORAD), and Short-Form (SF)-12 scores were compared between those who responded "not relevant" versus "not at all". RESULTS: Among 764 adults with atopic dermatitis, most had mild disease. The median (interquartile range [IQR]) POEM, PO-SCORAD, and DLQI scores were 5 (2-10), 24 (14-34), and 2 (1-6), respectively. Most (55.2%) also had at least one NRR, and 17.9% had 4 or more "not relevant" responses, with differences across several sociodemographic characteristics. There were no substantial differences in SF-12, POEM, and PO-SCORAD scores between those who responded "not relevant" versus "not at all". CONCLUSION: NRRs on the DLQI are common among adults with atopic dermatitis and differ across sociodemographic characteristics, suggesting issues with content validity. There is not a clear association between NRRs and other measures of disease severity among adults with mostly mild atopic dermatitis.

BACKGROUND: Perceived stigma among patients with psoriasis (PWP) is associated with poorer quality of life. OBJECTIVE: To determine the prevalence and predictors of stigmatizing attitudes that PWP expect and experience from others. METHODS: We conducted a survey using validated outcome measures to assess the extent to which PWP anticipate and perceive stigma from others. Demographic and clinical characteristics were obtained from electronic medical records. RESULTS: Patients (n = 106) were 48.11% female, 70.75% white, and had a mean age ± SD of 47.90 ± 16.19 years old. Of all, 25.47% self-reported their psoriasis as severe. Mean physician global assessment score ± SD was 2.98 ± 1.81. Two-thirds (66.98%) of patients reported that, in response to seeing their psoriasis-affected skin, they anticipated others to stereotype them as "contagious." Linear regression analyses demonstrated that patient-reported severe psoriasis, compared to mild psoriasis, was associated with greater anticipation of negative stereotypes, social avoidance, and perceived stigma from others (P values < .05). Physician-measured body surface area and global assessment scores were not significantly associated with any outcome. CONCLUSION: Prevalence of anticipated and perceived stigma among PWP is high. Our results suggest that objective measures of severity may not identify patients at risk of stigma-related distress. Additional methods, such as directly inquiring about stigmatizing experiences, may be needed.
RESUMO
BACKGROUND: Atopic dermatitis (AD) is associated with skin pain. However, little is known about the prevalence and associations of pain in AD. OBJECTIVE: To characterize the frequency, intensity, characteristics, and associations of pain from AD. METHODS: A cross-sectional, US population internet survey-based study of 602 adults with AD from the AD in America Study was performed (modified UK Working Party Criteria). RESULTS: Overall, 365 (61%) reported pain from AD, with 199 (33%) experiencing pain at least once per week and 30 (5%) with pain daily. Among those with AD pain, 22% reported worst pain intensity ≥7. The frequency and intensity of AD pain were associated with Patient-Oriented Scoring Atopic Dermatitis (PO-SCORAD), PO-SCORAD itch and sleep, and Patient-Oriented Eczema Measure (P ≤ .004 for all). Among those experiencing AD pain, 179 (48%) reported pain occurring only after frequent scratching, 156 (42%) reported intermittent pain, and 27 (11%) reported constant pain throughout the day. AD pain was most commonly associated with open areas caused by scratching (27%) and fissures in the skin (27%), followed by inflamed red skin (25%), with only a minority reporting pain mostly caused by burning from creams or ointments (10%). Mild AD was associated with more pain from scratching, whereas severe AD was associated with more constant pain and pain from inflamed skin. CONCLUSIONS: Pain is a distinct symptom in AD, with heterogeneous frequency, characteristics, intensity, and quality of life impact. Pain was related to scratching, fissures, and/or inflamed red skin, and least from burning from topical medications. Skin pain should be assessed in patients with AD and monitoring treatment response.

BACKGROUND: There are limited data about the impact of narrowband ultraviolet B phototherapy on patient-reported measures of health-related quality of life. OBJECTIVE: To evaluate the impact of adalimumab and phototherapy on health-related quality of life. METHODS: We examined patient-reported outcomes from a multicenter, randomized, placebo-controlled trial (ClinicalTrials.gov no. NCT01553058). The Dermatology Life Quality Index and EQ-5D-3L were evaluated every 4 weeks. RESULTS: We enrolled 97 patients: 30.9% were female, mean age was 43.5 years (standard deviation, 14.0), and median Psoriasis Area and Severity Index score was 16.7 (interquartile range, 13.9-21.6). At week 12, patients being treated with adalimumab (odds ratio [OR], 2.88; 95% confidence interval [CI], 1.02-8.17) and phototherapy (OR, 8.83; 95% CI, 2.47-31.57) were more likely to achieve the minimal clinically important difference in the Dermatology Life Quality Index compared with those receiving placebo. There were higher odds of achieving the minimal clinically important difference for the EQ-5D-3L Index score when comparing phototherapy versus placebo (OR, 9.78; 95% CI, 2.99-31.95) and phototherapy versus adalimumab (OR, 4.07; 95% CI, 1.42-11.70). LIMITATIONS: Small sample size, secondary analysis, generalizability. CONCLUSION: Phototherapy and adalimumab both improve skin-related quality of life and overall health-related quality of life compared with placebo in patients with psoriasis; however, patients treated with phototherapy achieved more improvement in overall health-related quality of life compared with patients treated with adalimumab.

Quality-of-life assessments are not standardized in atopic dermatitis (AD). We sought to determine the validity of the Short Form (SF)-12, a generic quality-of-life assessment, in AD and compare its measurement properties with the Dermatology Life Quality Index (DLQI). A cross-sectional, population-based study of 3,495 adults was performed, including 602 adults who met the modified United Kingdom Working Party Criteria for AD. The SF-12 mental component score and the SF-Six Dimension (SF-6D) had a strong correlation with each other and moderate inverse correlations with the Patient-Oriented Eczema Measure, the Patient-Oriented Scoring Atopic Dermatitis, the Patient-Oriented Scoring Atopic Dermatitis-itch, the Patient-Oriented Scoring Atopic Dermatitis-sleep, and the Numerical Rating Scale of pain (Pearson correlations, P < 0.0001 for all). The SF-12 mental component score and the SF-6D showed good discriminant validity as judged by the analysis of variance and receiver operating curves. The SF-12 physical component score had weak correlations with AD severity assessments and poor discriminant validity. The DLQI had better convergent and discriminant validity than the SF-12. The SF-12 and the DLQI showed good internal consistency (Cronbach alpha, 0.89 and 0.94, respectively). Differential item functioning was found for items in the SF-12 and the DLQI. Floor effects were observed for the DLQI but not for the SF-12 mental component score, the SF-12 physical component score, and the SF-6D. Severity thresholds were selected. In conclusion, the SF-12 mental component score and the SF-6D showed good validity in AD but inferior construct validity compared with the DLQI.
