ABSTRACT

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.

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

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

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.

ABSTRACT

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.

ABSTRACT

BACKGROUND: Atopic dermatitis (AD) is a common inflammatory disease of the skin that begins early in life and can be lifelong. The purpose of our study was to evaluate whether fetal exposure and/or early life exposure of a child to antibiotics increases the risk of early onset AD. OBJECTIVE: We hypothesize that antibiotic exposure in utero or early in life (e.g., first 90 days) increases the likelihood that children develop AD. METHODS: Utilizing a large prospectively collected electronic medical records database, we studied the association of antibiotic exposure received in utero or very early in life and the relative risk of onset of AD in a population-based cohort study. Associations were estimated using proportional hazards models as hazard ratios (HR) with 95% confidence intervals (CI). RESULTS: The risk of AD in childhood was increased after in utero or early life antibiotic exposure. For any in utero AB exposure the HR was 1.38 (1.36,1.39). However, penicillin demonstrated the strongest association with AD for both in utero exposure, 1.43 (1.41,1.44), and for childhood exposure, 1.81(1.79,1.82). HRs were higher in children born to mothers without AD than those with AD pointing to effect modification by maternal AD status. CONCLUSION: Children born to mothers exposed to antibiotics while in utero had, depending on the mother's history of AD, approximately a 20 to 40% increased risk of developing AD. Depending on the antibiotic, children who received antibiotics early-in-life had a 40 to 80% increased risk of developing AD. Our study, supports and refines the association between incident AD and antibiotic administration. It also adds population-based support to therapeutic attempts to treat AD by modifying skin microbiome.

ABSTRACT

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 1 809 029 pediatric controls were matched to 409 431 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 (936 750 [51.8%] controls, 196 996 [51.6%] with mild AD, 11 379 [50.7%] with moderate AD, and 2985 [56.1%] with severe AD), and with similar socioeconomic status. A total of 2 678 888 adult controls were matched to 625 083 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 (1 445 589 [54.0%] controls, 256 071 [62.3%] with mild AD, 109 404 [55.8%] with moderate AD, and 10 736 [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.

ABSTRACT

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.

ABSTRACT

BACKGROUND: The relationship between atopic dermatitis (AD) severity, sleep disturbance (SD), and health-related outcomes is not fully elucidated. OBJECTIVE: The aim of the study was to determine the prevalence of SD in adult AD and its relationship with AD severity and health outcomes among the US population. METHODS: A cross-sectional, US population-based survey study of 2893 adults was performed. RESULTS: Among adults meeting the UK Diagnostic Criteria for AD, 255 (40.7%) reported 1 or more, 67 (11.1%) reported 3 to 4, and 57 (9.5%) reported 5 to 7 nights of SD in the past week; 475 (79.7%) reported at least some trouble sleeping in the past 3 days. Moderate and severe Patient-Oriented Scoring AD, Patient-Oriented Eczema Measure, and Numeric Rating Scale-itch and Numeric Rating Scale-skin pain scores were associated with more severe SD compared with those without AD. More frequent and severe SDs were associated with higher Dermatology Life Quality Index, lower 12-item Short-Form Health Survey, and higher Hospital Anxiety and Depression Scale (HADS) scores. Significant mediation by SD severity was observed between Patient-Oriented Eczema Measure and Numeric Rating Scale-itch with Dermatology Life Quality Index, 12-item Short-Form Health Survey physical and mental component scores, HADS-anxiety and HADS-depression scores, diagnosed anxiety, and heart disease. CONCLUSIONS: Atopic dermatitis and AD severity are associated with SDs. Sleep disturbances considerably impact quality of life and other health outcomes in adults with AD.

ABSTRACT

Atopic Dermatitis (AD) is a chronic, inflammatory skin condition that imposes an enormous personal and economic burden in the United States. Due to the ubiquity of the use of electronic medical records (EMR) in the United States, utilizing such data is critically important to studying common dermatologic diseases, such as AD. Our goal was to create a simple-to-use algorithm applied to EMR data to accurately identify AD patients thereby making it possible to efficiently use EMR data to ascertain and then study individuals with AD. Our results suggest that the algorithm that is most likely to accurately identify AD patients from the EMR based on PPV utilizes ICD-10 code for L20.89, L20.9, or L20.84 in conjunction with a diagnosis code for asthma or allergic rhinitis, treatment code, and dermatology consult code. This approach yields a PPV of 95.00% in our training cohort and 100.00% in our validation cohort. Therefore, future studies can use this algorithm to better assure that a subject has AD for studies of the pathogenesis and/or potential treatment targets of AD.

ABSTRACT

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.

ABSTRACT

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.
