Maintenance of Investigator's Static Global Assessment Response with Once-Daily Crisaborole in Participants with Mild to Moderate Atopic Dermatitis.

INTRODUCTION: Treatments for atopic dermatitis (AD) often fail to achieve lasting disease control. In the CrisADe CONTROL phase III study (ClinicalTrials.gov: NCT04040192), participants aged ≥ 3 months with mild to moderate AD treated with once-daily (QD) crisaborole, following initial treatment success with crisaborole twice daily (BID), had longer periods of flare-free maintenance, a higher number of flare-free days, and a lower number of flares compared with those who received vehicle. The study was an exploratory analysis of data on the maintenance of response per Investigator's Static Global Assessment (ISGA; ISGA score of 0 [clear] or 1 [almost clear]) during the CrisADe CONTROL study through week 52. METHODS: Exploratory endpoints were the time to ISGA response during the open-label run-in period, and the maintenance of ISGA response and the severity and duration of flares during the double-blind maintenance period. Outcomes were stratified by age (participants aged 3 months to < 12 years and ≥ 12 years) and duration of crisaborole BID treatment (< 4 weeks or ≥ 4 weeks) during the open-label run-in period. RESULTS: During the open-label run-in period, the median time to ISGA response was 41.5 days. From week 4 to week 52 of the double-blind maintenance period, the proportion of participants who maintained ISGA response was greater with crisaborole versus vehicle, and this difference was statistically significant up to week 36 (P < 0.05). Duration of flare periods during the maintenance period were 54.1 and 54.0 days for the vehicle and crisaborole-treated groups, respectively. Numerically fewer crisaborole-treated participants experienced a flare with an ISGA score of ≥ 2 compared with vehicle-treated participants (64.8% vs. 74.4%, respectively). Findings were comparable across most subgroups. CONCLUSIONS: Adult and pediatric participants with mild to moderate AD at baseline who had achieved responder criteria (treatment success) with crisaborole BID during the run-in period maintained response per ISGA with crisaborole QD during the double-blind maintenance period through week 52. TRIAL REGISTRATION: ClinicalTrials.gov: NCT04040192.

Atopic dermatitis is a skin disease that causes itchy, red, and dry patches of skin that can affect a person for a long time. Current treatments for atopic dermatitis often fail to keep the symptoms under control. Some creams and ointments applied to the skin (known as topical treatments) can ease the discomfort of atopic dermatitis. Crisaborole is a steroid-free ointment that has been shown to improve symptoms of atopic dermatitis in clinical studies. In a study called the CrisADe CONTROL trial, crisaborole was tested to see if it can keep atopic dermatitis symptoms under control. People who participated in the study were aged 3 months and older and they had mild-to-moderate atopic dermatitis. Participants were asked to use crisaborole on their itchy, red, and dry skin twice daily for 8 weeks. Patients were called "responders" if their symptoms became nearly clear or completely clear based on a doctor's assessment called the Investigator's Static Global Assessment, which rates atopic dermatitis between clear to severe. Some responders were asked to use crisaborole once daily for 52 weeks and another group of responders was asked to use a control (an ointment with no medicine) once daily for 52 weeks. Investigators looked at how long the skin remained nearly clear or completely clear during the 52 weeks. Results of this study showed that after initial treatment success with crisaborole twice daily, adult and pediatric participants who had mild-to-moderate atopic dermatitis were able to keep their skin nearly clear or completely clear with crisaborole once daily.

Patients' and caregivers' perspectives of the atopic dermatitis journey.

BACKGROUND: Understanding the patient journey is important to optimize care for patients with atopic dermatitis (AD) and overcome challenges in diagnosis and management. OBJECTIVE: To explore patient and caregiver perspectives regarding their experience with AD. METHODS: Patients and caregivers of patients with AD completed a pre-meeting survey and were invited to join an advisory board meeting in their country (China, Hong Kong, Ireland, Japan and Lebanon) to discuss the survey results. Data were analyzed descriptively. RESULTS: The survey included 31 participants (patients and caregivers) from Hong Kong (n = 7), China (n = 7), Ireland (n = 6), Japan (n = 6) and Lebanon (n = 5). The most challenging factors in the AD journey were management of symptoms before a confirmed diagnosis (68%), sudden recurrence of flares or worsening of symptoms (68%) and lifestyle changes (52%). In terms of overall AD management, 35% of participants indicated that AD was managed well, 23% had a clear treatment plan and 19% were generally satisfied with disease management. A collaborative relationship with healthcare professionals was favored. CONCLUSION: A holistic assessment of AD includes understanding patient and caregiver preferences, needs, experiences and disease perceptions. Addressing the identified gaps may improve the management of AD.

Impact of Crisaborole in Treatment-Experienced Patients With Mild-to-Moderate Atopic Dermatitis.

Background: Crisaborole ointment, 2%, is a nonsteroidal phosphodiesterase 4 inhibitor for the treatment of patients with mild-to-moderate atopic dermatitis (AD). Objective: To assess the efficacy and safety of crisaborole in patients with AD who had received prior treatment with (a) corticosteroids (systemic or topical) or topical calcineurin inhibitors (TCIs) or (b) topical corticosteroids (TCSs) or TCIs or (c) who were treatment-naive (TN). Methods: This post hoc analysis comprised patients aged ≥2 years with mild-to-moderate AD. Patients were assigned (2:1) to receive crisaborole or vehicle twice daily for 28 days. Patient response was assessed with the Investigator's Static Global Assessment (ISGA), Dermatology Life Quality Index (DLQI), Children's Dermatology Life Quality Index (CDLQI), and Dermatitis Family Impact (DFI) tools. Safety was also assessed. Results: A significantly higher percentage of patients treated with crisaborole versus vehicle achieved ISGA success regardless of treatment history. Patients treated with crisaborole had significant reductions in DLQI, CDLQI, and DFI scores versus those who received vehicle regardless of treatment history, with the exception of DLQI and DFI scores in the TN group. Crisaborole was well tolerated in all subgroups. Conclusion: Crisaborole demonstrated a favorable efficacy and safety profile in both treatment-experienced and TN patients.

Cutaneous Components Leading to Pruritus, Pain, and Neurosensitivity in Atopic Dermatitis: A Narrative Review.

Atopic dermatitis (AD) is a chronic, relapsing immunoinflammatory skin condition characterized by sensations such as pruritis, pain, and neuronal hypersensitivity. The mechanisms underlying these sensations are multifactorial and involve complex crosstalk among several cutaneous components. This review explores the role these components play in the pathophysiology of atopic dermatitis. In the skin intercellular spaces, sensory nerves interact with keratinocytes and immune cells via myriad mediators and receptors. These interactions generate action potentials that transmit pruritis and pain signals from the peripheral nervous system to the brain. Keratinocytes, the most abundant cell type in the epidermis, are key effector cells, triggering crosstalk with immune cells and sensory neurons to elicit pruritis, pain, and inflammation. Filaggrin expression by keratinocytes is reduced in atopic dermatitis, causing a weakened skin barrier and elevated skin pH. Fibroblasts are the main cell type in the dermis and, in atopic dermatitis, appear to reduce keratinocyte differentiation, further weakening the skin barrier. Fibroblasts and mast cells promote inflammation while dermal dendritic cells appear to attenuate inflammation. Inflammatory cytokines and chemokines play a major role in AD pathogenesis. Type 2 immune responses typically generate pruritis, and the type 1 and type 3 responses generate pain. Type 2 responses and increased skin pH contribute to barrier dysfunction and promote dysbiosis of the skin microbiome, causing the proliferation of Staphyloccocus aureus. In conclusion, understanding the dynamic interactions between cutaneous components in AD could drive the development of therapies to improve the quality of life for patients with AD.

Adult, adolescent, and caregiver preferences for attributes of topical treatments for mild-to-moderate atopic dermatitis: a discrete-choice experiment.

Purpose: Topical treatments for mild-to-moderate (MM) atopic dermatitis (AD) include emollients, corticosteroids, calcineurin inhibitors, a Janus kinase inhibitor, and a phosphodiesterase 4 inhibitor, which differ in multiple ways. This study aimed to quantify the conditional relative importance (CRI) of attributes of topical treatments for MM AD among adult and adolescent patients and caregivers of children with MM AD.Materials and methods: A discrete-choice experiment (DCE) survey was administered to US adults and adolescents with MM AD and caregivers of children with MM AD. Each choice task comprised 2 hypothetical topical treatments characterized by efficacy, adverse events, vehicle, and application frequency. Data were analyzed using a random-parameters logit model to calculate the CRI of each attribute.Results and conclusions: 300 adults, 331 adolescents, and 330 caregivers completed the DCE. Avoiding changes in skin color (CRI 29.0) and time until itch improves (26.6) were most important to adults, followed by time until clear/almost clear skin (17.8). Application frequency (3.0) did not have a statistically significant impact on adults' choices. Adolescents were less concerned about changes in skin color than adults or caregivers; caregivers were less concerned about time until clear/almost clear skin than patients. Physicians should consider age-relevant aspects of preferences in treatment discussions with patients and caregivers.

Comorbidities in childhood atopic dermatitis: A population-based study.

BACKGROUND: Atopic dermatitis (AD) is a chronic inflammatory skin disease that is associated with allergic comorbidities. However, studies examining comorbidities in childhood AD are incomplete, which may contribute to suboptimal care. OBJECTIVE: The objective was to compare the risk of developing different allergic and non-allergic comorbidities among children with AD to that of a matched non-AD reference cohort in Sweden. METHODS: This was a nationwide population-based cohort study using longitudinal data from primary and specialist care registers. Patients with AD were identified by confirmed diagnosis in primary or specialist care. The non-AD reference cohort was randomly drawn from the general population and matched 1:1 with the AD patients. The risk of developing the following conditions was evaluated: hypersensitivity and allergic disorders, neurological disorders, psychiatric disorders, infections, immunological and inflammatory disorders, Type 1 diabetes (T1D), endocrine and metabolic disorders, skeletal disorders, ocular disorders and malignancies. RESULTS: This study included 165,145 patients with AD (mild-to-moderate [n = 126,681] and severe [n = 38,464]) and an equally sized reference cohort. Patients with AD displayed a higher risk of developing comorbid conditions for all investigated categories, except for T1D and skeletal disorders, compared with the reference cohort. The highest risk compared with the reference cohort was observed for hypersensitivity and allergic disorders (hazard ratio [HR]: 3.87), followed by malignancies (HR: 2.53) and immunological and inflammatory disorders (HR: 2.36). Patients with AD also had higher risk of developing multiple comorbidities (≥2). The risk of comorbidity onset increased alongside AD severity and patients with active AD were associated with increased risk of comorbidity onset compared with patients in remission. CONCLUSIONS: The clinical burden of AD is substantial for children with AD and patients are at an increased risk of developing several comorbid conditions extending beyond the atopic march. Our results also showed a positive association between worsening severity of AD and an increased risk of comorbidity onset.

Similarities and differences in peripheral itch and pain pathways in atopic dermatitis.

Atopic dermatitis (AD) is predominantly characterized by intense itching, but concomitant skin pain is experienced by more than 40% of patients. Patients with AD display considerable somatosensory aberrations, including increased nerve sensitivity to itch stimuli (hyperknesis), perception of itch from innocuous stimuli (alloknesis), or perception of pain from innocuous stimuli (allodynia). This review summarizes the current understanding of the similarities and differences in the peripheral mechanisms underlying itch and pain in AD. These distinct yet reciprocal sensations share many similarities in the peripheral nervous system, including common mediators (such as serotonin, endothelin-1, IL-33, and thymic stromal lymphopoietin), receptors (such as members of the G protein-coupled receptor family and Toll-like receptors), and ion channels for signal transduction (such as certain members of the transient receptor potential [TRP] cation channels). Itch-responding neurons are also sensitive to pain stimuli. However, there are distinct differences between itch and pain signaling. For example, specific immune responses are associated with pain (type 1 and/or type 3 cytokines and certain chemokine C-C [CCL2, CCL5] and C-X-C [CXCL] motif ligands) and itch (type 2 cytokines, including IL-31, and periostin). The TRP melastatin channels TRPM2 and TRPM3 have a role in pain but no known role in itch. Activation of µ-opioid receptors is known to alleviate pain but exacerbate itch. Understanding the connection between itch and pain mechanisms may offer new insights into the treatment of chronic pain and itch in AD.

Stasis Dermatitis: The Burden of Disease, Diagnosis, and Treatment.

Stasis dermatitis (SD), an inflammatory dermatosis occurring on the lower extremities, is a cutaneous manifestation of chronic venous insufficiency (CVI). SD is associated with a significant burden of disease. Symptoms such as pain, swelling, and itching can be debilitating for patients, leading to poor sleep, loss of mobility, and the inability to perform daily activities, and can interfere with work and leisure activities. Moreover, SD is a progressive disease with serious secondary complications such as ulcerations, which increase the patients' morbidity, reduce their quality of life, and increase health care burden. Challenges in diagnosing patients may have both short- and long-term sequalae for the patients due to unnecessary treatment and management. In addition, misdiagnosis may result in hospitalizations, placing additional burden on health care professionals in terms of time and financial burden on the health care system. Compression therapy and leg elevation represent the mainstay of treatment for CVI; however, it is also difficult to self-manage, which places a substantial burden on patients and caregivers. Moreover, compression therapy may cause discomfort and exacerbate itching. Subsequent nonadherence may result in disease progression that places additional burden on the physicians who manage these patients and the health care system in terms of resources required and costs incurred. A large proportion of patients with SD develop allergic contact dermatitis because of innate immune signals and altered skin barrier predisposing to sensitization to topical prescriptions, over-the-counter medications, and compression devices used to treat SD. Other than topical corticosteroids, there are no approved pharmacological options to treat inflammation in SD.

Potential application of PS-OCT in the safety assessment of non-steroidal topical creams for atopic dermatitis treatment.

Crisaborole 2% ointment is a non-steroidal treatment for mild-moderate atopic dermatitis (AD) and may produce fewer adverse effects than topical corticosteroids (TCS). We used PS-OCT to quantify dermal collagen at baseline and after 29 days of treatment with crisaborole and betamethasone valerate (BMV), in 32 subjects. PS-OCT detected a mean increase 1 × 10-6, 95% CI (6.3, 1.37) × 10-6 in dermal birefringence following TCS use (p < 0.0001, ad-hoc, not powered), whereas a change of -4 × 10-6, 95% CI (-32, 24) × 10-6 was detected for crisaborole (p = 0.77, ad-hoc, not powered). These results could suggest a differential effect on dermal collagen between the two compounds. PS-OCT may thus find an important role in safety assessment of novel AD treatment' and larger trials are warranted.

Activity-limiting Injury in Adults: United States, 2020-2021.

Injuries can have physical (1), psychological (2,3), and economic (4) consequences, including problems with wound repair and persistent pain. Additionally, the consequences of injury may interfere with normal activities and return to work (1). This report describes the percentage of adults who had an injury that limited their usual activities in the past 3 months (an activitylimiting injury) by selected sociodemographic characteristics from the 2020 and 2021 National Health Interview Survey (NHIS).

Crisaborole reverses dysregulation of the mild to moderate atopic dermatitis proteome toward nonlesional and normal skin.

BACKGROUND: Safe and effective long-term topical treatments for atopic dermatitis (AD) remain limited. OBJECTIVE: In this phase 2a, single-center, intrapatient, and vehicle-controlled study, we examine the mechanism of action of crisaborole 2% ointment, a topical nonsteroidal PDE4 (phosphodiesterase-4) inhibitor, in a proteomic analysis of 40 adults with mild to moderate AD and 20 healthy subjects. METHODS: Within the AD cohort, 2 target lesions were randomized in an intrapatient (1:1) manner to double-blind crisaborole/vehicle applied twice daily for 14 days. Punch biopsy specimens were collected for biomarker analysis at baseline from all participants, then from AD patients only at day 8 (optional) and day 15. RESULTS: Compared to the vehicle, crisaborole significantly reversed dysregulation of the overall lesional proteome and of key markers and pathways (eg, Th2, Th17/Th22, and T-cell activation) associated with AD pathogenesis toward both nonlesional and normal skin. Significant clinical correlations were observed with markers associated with nociception and Th2, Th17, and neutrophilic activation. LIMITATIONS: Study limitations include predominance of white patients in the cohort, relatively short treatment time, and regimented administration of crisaborole. CONCLUSION: Our results demonstrate crisaborole-induced normalization of the AD proteome toward a nonlesional molecular phenotype and further support topical PDE4 inhibition in the treatment of mild to moderate AD.

Stasis Dermatitis: An Overview of Its Clinical Presentation, Pathogenesis, and Management.

Stasis dermatitis is a chronic inflammatory skin disease of the lower extremities. It typically occurs in older individuals and is the cutaneous manifestation of venous hypertension caused by venous reflux. Such retrograde venous blood flow is the result of incompetent venous valves, valve destruction, or venous obstruction. Stasis dermatitis is eczematous. The associated impairment of venous valves may cause swelling of the legs, leading to serious conditions including venous ulcerations. Diagnosis can be challenging because of its clinical resemblance to other skin conditions and poor clinical recognition by physicians. The cornerstones of stasis dermatitis treatment are compression therapy to ameliorate pain and swelling, topical treatments to alleviate secondary skin changes, and interventional treatment options to correct the underlying causes of venous reflux. Given the central role of inflammation of the lower extremities in driving the cutaneous changes characteristic of stasis dermatitis, new therapeutic approaches that target the inflammation are under clinical evaluation in patients with stasis dermatitis.

Stasis dermatitis is a skin disease that can affect a person for a long time. It affects the legs of older people who have a disease called chronic venous insufficiency. This is when a person's veins have difficulty sending blood from their limbs back to their heart. Stasis dermatitis is caused by increased pressure inside a person's veins. Its signs and symptoms are skin discoloration, itch, dryness, and scaling and can be similar to the signs and symptoms of cellulitis and allergic contact dermatitis. Cellulitis is a common skin infection caused by bacteria. Cellulitis causes redness, swelling, and pain. Allergic contact dermatitis is an itchy skin rash caused by contact with something that irritates the skin. Stasis dermatitis is usually diagnosed after a healthcare provider has looked at person's skin and their medical history. Treatment for stasis dermatitis should treat the chronic venous insufficiency that causes the disease. It should also treat the skin lesions caused by stasis dermatitis. One way to treat stasis dermatitis is to reduce pain and swelling. This is done by applying pressure with compression stockings or bandages. Minor surgery can treat the venous insufficiency that causes stasis dermatitis. No treatments have been approved for the skin symptoms associated with stasis dermatitis. New ways to treat such symptoms need to be developed.

Healthcare Resource Utilization and Direct Cost of Patients with Atopic Dermatitis in Dubai, United Arab Emirates: A Retrospective Cohort Study.

Introduction: Atopic dermatitis (AD) data are scarce in Dubai [United Arab Emirates (UAE)]. Therefore, this study aimed at understanding real-world healthcare resource utilization (HCRU) and related costs, specialties, treatment landscape, consultation-based prevalence and incidence, and patient characteristics. Methods: This retrospective, longitudinal, insurance e-claims (Dubai Private Insurance-insured expatriates) database studied AD in Dubai between 1 January 2014 and 31 March 2020. Two cohorts of patients based on treatment status as the eligibility criteria were selected from 442,956 patients with at least two AD diagnosis claims: treated AD [mild to moderate (10,134 patients) and moderate to severe (3515 patients)] and untreated or on drugs not included in the treated AD cohort (10,806 patients). Results: Across treated AD (mild to moderate and moderate to severe) and untreated AD cohorts, mean age was ~ 29 years; the majority were from dermatology (65-44%) and pediatrics (29-32%) specialty. Key HCRU cost contributors were hospitalizations and outpatient visits in both the treated AD groups. Mean annual disease-specific HCRU cost per patient was highest for the moderate-to-severe treated (531.5 USD) cohort, followed by the mild-to-moderate treated (378.4 USD) cohort, and lowest for the untreated (144.0 USD) cohort; patients with AD with any infection, asthma, or allergic rhinitis showed a similar trend. However, AD-diagnosed patients with Staphylococcus infection had the highest mean HCRU cost among the mild-to-moderate treated AD cohort, followed by the moderate-to-severe treated AD cohort. Conclusion: This study indicated AD to be a common skin disease with a prevalence rate of 4-5% in Dubai (UAE), with the majority of patients (about 90%) being treated by specialists. However, there is a significant underuse of newer innovative therapies (including biologics). Also, disease severity (moderate-to-severe AD) was associated with high direct medical cost, which could be controlled by early intervention. Furthermore, AD treatment choice could focus on major direct HCRU cost contributors such as hospitalizations, comorbid conditions, and infections.

Recent Developments and Advances in Atopic Dermatitis: A Focus on Epidemiology, Pathophysiology, and Treatment in the Pediatric Setting.

Atopic dermatitis (AD) is a chronic inflammatory skin disorder that affects a substantial number of children and has a significant negative impact on affected patients and their caregivers/families. Recent studies have led to significant evolutions in the understanding of AD pathogenesis, epidemiology, and treatment. The first point of contact for many patients with new-onset AD is usually with their primary care provider or pediatrician. This underscores the importance for pediatricians to understand the basic pathophysiology and current standards of care for AD. This article provides up-to-date information and reviews the basic principles of AD pathophysiology, diagnosis, and management. In addition, the article highlights recent advances in scientific research regarding the mechanisms involved in the pathogenesis of atopic dermatitis that have resulted in the discovery of novel therapeutic targets and the development of targeted biologic therapies with the potential to revolutionize AD therapy.

Dental Care Utilization Among Adults Aged 18-64: United States, 2019 and 2020.

Oral health is an essential component of overall health and well-being (1,2). Along with good oral hygiene, an important factor of oral health is regular dental care (3). However, about 35% of adults aged 18 and over did not have a dental visit in 2019 (4), and predictors such as age, race, sex, and socioeconomic status were associated with delayed dental care among adults in the United States (5). In 2020, many dental practices limited their hours and services in response to the COVID-19 pandemic (6,7). This report uses data from the 2019 and 2020 National Health Interview Survey (NHIS) to describe recent changes in the prevalence of dental visits among adults aged 18-64.

Clinical and Humanistic Burden of Atopic Dermatitis in Europe: Analyses of the National Health and Wellness Survey.

INTRODUCTION: Atopic dermatitis (AD) is a chronic and relapsing inflammatory skin disease that negatively impacts overall health, quality of life (QoL), and work productivity. Prior studies on AD burden by severity have focused on moderate-to-severe disease. Here, we describe the clinical and humanistic burden of AD in Europe across all severity levels, including milder disease. METHODS: Data were analyzed from the 2017 National Health and Wellness Survey from adult respondents with AD in the EU-5 (France, Germany, Italy, Spain, and the UK). AD disease severity was defined based on self-reported assessments as "mild," "moderate," or "severe" and by Dermatology Life Quality Index (DLQI) severity bands. Self-reported outcomes for AD respondents by severity were assessed using propensity score matching. These outcomes included a wide range of selected medical/psychological comorbidities, overall QoL and functional status (EuroQol 5-Dimensions 5-Level and Short Form-36 version 2 questionnaires), and work productivity and activity impairment (Work Productivity and Activity Impairment questionnaire). RESULTS: In total, 4208 respondents with AD (mild AD, 2862; moderate AD, 1177; severe AD, 169) and 4208 respondents without AD were included in this analysis. Results showed greater burden across severity levels compared with matched non-AD controls. A higher proportion of respondents with mild-to-moderate AD, defined by DLQI severity bands, reported atopic comorbidities (P < 0.05) and a wide range of cardiac, vascular, and metabolic comorbidities, including hypertension, high cholesterol, angina, and peripheral vascular disease (P < 0.005), compared with non-AD controls. Relative to potential impacts of various medical and psychological burdens, respondents with mild-to-moderate AD reported higher activity impairment than controls (P < 0.0001). CONCLUSION: Clinical and humanistic burden was observed in European respondents with AD compared with matched non-AD controls across severity levels, with burden evident even in milder disease, highlighting the importance of improving disease management in early stages of AD.
