RESUMO
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.

Multiple risk factors have been associated with the development of atopic dermatitis (AD). Recent advances in understanding the role of genetics in this disease have been made, with discovery of the filaggrin (FLG) gene as the most notable so far. In addition to FLG gene mutations as a risk factor for AD, a positive family history of atopic or allergic disease in either parent has been shown to confer a greater risk of developing AD. Atopic dermatitis usually presents early in life and is thought to represent the initial step in the "atopic march," which is characterized by the development of other atopic diseases later in life such as asthma, allergic rhinitis, and/or rhinoconjunctivitis, food allergies, and hay fever. Other comorbid diseases that have been associated with AD include increase risk of viral and bacterial skin infections, neuropsychiatric diseases such as attention-deficit hyperactivity disorders (ADHD), and autistic spectrum disorder (ASD). Patients with AD have also been found to have worse sleep quality overall compared to patients without AD. In this chapter, we will discuss the risk factors associated with development of atopic dermatitis as well as the most commonly reported comorbidities in patients with this disease.

BACKGROUND: Atopic dermatitis (AD) is an inflammatory disorder characterized by dominant type 2 inflammation leading to chronic pruritic skin lesions, allergic comorbidities, and Staphylococcus aureus skin colonization and infections. S aureus is thought to play a role in AD severity. OBJECTIVES: This study characterized the changes in the host-microbial interface in subjects with AD following type 2 blockade with dupilumab. METHODS: Participants (n = 71) with moderate-severe AD were enrolled in a randomized (dupilumab vs placebo; 2:1), double-blind study at Atopic Dermatitis Research Network centers. Bioassays were performed at multiple time points: S aureus and virulence factor quantification, 16s ribosomal RNA microbiome, serum biomarkers, skin transcriptomic analyses, and peripheral blood T-cell phenotyping. RESULTS: At baseline, 100% of participants were S aureus colonized on the skin surface. Dupilumab treatment resulted in significant reductions in S aureus after only 3 days (compared to placebo), which was 11 days before clinical improvement. Participants with the greatest S aureus reductions had the best clinical outcomes, and these reductions correlated with reductions in serum CCL17 and disease severity. Reductions (10-fold) in S aureus cytotoxins (day 7), perturbations in TH17-cell subsets (day 14), and increased expression of genes relevant for IL-17, neutrophil, and complement pathways (day 7) were also observed. CONCLUSIONS: Blockade of IL-4 and IL-13 signaling, very rapidly (day 3) reduces S aureus abundance in subjects with AD, and this reduction correlates with reductions in the type 2 biomarker, CCL17, and measures of AD severity (excluding itch). Immunoprofiling and/or transcriptomics suggest a role for TH17 cells, neutrophils, and complement activation as potential mechanisms to explain these findings.

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 90â 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.
RESUMO
BACKGROUND: Atopic dermatitis (AD) is associated with immunological dysfunction, which may influence cancer development. Previous studies of AD and cancer demonstrate inconsistent results and few of these studies examined children or AD severity and treatment. OBJECTIVES: To determine malignancy risk among children and adults with AD. METHODS: We conducted a cohort study using electronic health records data from UK general practices in The Health Improvement Network between 1994 and 2015. Children (< 18â years old) and adults (≥ 18â years old) with AD were matched on age, practice and index date to patients without AD. AD was categorized as mild, moderate or severe using treatments and dermatology referrals as proxies. The primary outcome was any incident malignancy, including in situ malignancy, identified using diagnosis codes and categorized into haematological, skin and solid organ malignancies. Secondary outcomes included specific malignancies: leukaemia, lymphoma, melanoma, nonmelanoma skin cancer (NMSC) and common solid-organ cancers. RESULTS: Among 409 431 children with AD (93.2% mild, 5.5% moderate, 1.3% severe) and 1 809 029 children without AD who had median follow-up of 5-7â years, the incidence rates of malignancy were 1.9-3.4 and 2.0 per 10 000 person-years (PY), respectively. The adjusted risk of malignancy overall did not differ with respect to AD [hazard ratio (HR) 1.02 (95% confidence interval 0.92-1.12)]. Severe AD was associated with increased lymphoma risk [HR 3.18 (1.41-7.16), excluding cutaneous T-cell lymphoma (CTCL)], and mild AD was associated with increased NMSC risk [1.55 (1.06-2.27)]. Among 625 083 adults with AD (65.7% mild, 31.4% moderate, 2.9% severe) and 2 678 888 adults without AD who had median follow-up of 5â years, incidence rates of malignancy were 97.4-125.3 per 10 000 PY and 103.7 per 10 000 PY, respectively. The adjusted risk of any malignancy did not differ with respect to AD [HR 1.00 (0.99-1.02)]. However, adults with severe AD had a twofold higher risk of non-CTCL lymphoma. AD was also associated with slightly higher skin cancer risk [HR 1.06 (1.04-1.08)] and slightly lower solid cancer risk [0.97 (0.96-0.98)] but results varied by specific cancers and AD severity. CONCLUSIONS: Epidemiological evidence does not support a strong overall malignancy risk in AD but lymphoma risk may be increased with severe AD.

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.

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.

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: Atopic dermatitis (AD) is a common chronic relapsing skin disease. Genetic variants have been associated with skin barrier function and immune regulation. Thymic stromal lymphopoietin (TSLP), an immune regulator, has been previously associated with AD. OBJECTIVE: To fine map TSLP and evaluate associations with the onset and persistence of AD. METHODS: TSLP variation was determined using targeted massively parallel sequencing in a longitudinal cohort of children with AD. Evaluations included linkage disequilibrium and the persistence of AD for as many as 10 years of follow-up. The association between the presence of AD and rs1898671 variation was evaluated in a second independent cohort. RESULTS: The minor variant frequency for rs1898671 was 23.5% (95% CI, 21.4%-25.8%). This variant was not in linkage disequilibrium with other TSLP variants in the longitudinal cohort (n = 741). White children with AD were less likely to have rs1898671 variant (odds ratio [OR], 1.41; 95% CI, 1.20-1.66) than Genome Aggregation Database controls. Children with AD and the rs1898671 variant during follow-up were more likely to have remission than children who were wild type for rs1898671 (OR, 1.56; 95% CI, 1.26-1.91). In the second cohort (n = 585), the rs1898671 variant was less prevalent in those with AD than those without. The protective effect was greater in rs1898671 heterozygotes (OR, 1.91; 95% CI, 1.34-2.75) than homozygotes (OR, 1.28; 95% CI, 0.61-2.70). CONCLUSION: TSLP and specifically rs1898671 are important in the pathogenesis of AD and could represent a potential clinical target for the development of therapies to treat individuals with AD.

BACKGROUND: There has been an increase in the number of psoriasis treatments being investigated in clinical trials. Patients may have undiagnosed issues at the start of a study which may become identified during follow-up as incident medicinal conditions. The prevalence of incidental findings in patients with moderate-to-severe psoriasis presenting for clinical trials is unknown. OBJECTIVE: Determine the prevalence of incidentalomas and rate of malignancy identified by fludeoxyglucose F 18 (FDG) positron emission tomography/computed tomography (PET/CT) imaging in clinical trial patients with moderate-to-severe psoriasis. METHODS: A cross-sectional secondary analysis of patients with moderate-to-severe psoriasis who underwent FDG PET/CT scans at the baseline visit, before randomization, for 3 phase 4 clinical trials on vascular inflammation in psoriasis. Only patients without active infection, malignancy, or uncontrolled comorbidities were eligible for the clinical trials. RESULTS: A total of 259 healthy patients with moderate-to-severe psoriasis underwent an FDG PET/CT scan as part of the study procedures. In all, 31 patients (11.97%) (95% confidence interval [CI], 8.28-16.56) had clinically significant incidentalomas on the baseline FDG PET/CT scan. Univariate logistic regression demonstrated that with every increase of 10 years of age, there was an approximate 30% increased risk of discovery of an incidentaloma (odds ratio, 1.30; 95% CI, 1.01-1.68). Of those patients with findings suggestive of malignancy (n = 28), 6 were confirmed to have cancer, resulting in a 2.31% (95% CI, 0.9-5.0) prevalence of malignancy. The positive predictive value of a true cancer was 31.58% (range, 21%-54%). LIMITATIONS: Generalizability and lost to follow-up. CONCLUSION: Incidentalomas on FDG PET/CT imaging are common in otherwise healthy, asymptomatic patients with moderate-to-severe psoriasis in clinical trials. Our results can help inform interpretation of clinical trial safety data and emphasize the importance of compliance with cancer screening recommendations.

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.

Aims: To determine the risk of venous thromboembolism (VTE) defined as the combined endpoint of deep venous thrombosis (DVT) and pulmonary embolism (PE) among patients with psoriatic arthritis (PsA), psoriasis and rheumatoid arthritis (RA) compared with population controls. Methods and results: A cohort study was conducted in a primary care medical record database in the UK with data from 1994-2014 among patients with PsA, RA, or psoriasis. Cox proportional hazards models were used to calculate the relative hazards for DVT, PE, and VTE. An interaction with disease modifying anti-rheumatic drugs (DMARD) was hypothesized a priori and was significant. Patients with PsA (n = 12 084), RA (n = 51 762), psoriasis (n = 194 288) and controls (n = 1 225 571) matched on general practice and start date were identified. Patients with RA (with and without a DMARD prescription) and patients with mild psoriasis had significantly elevated risks of VTE (HR 1.35, 1.29, and 1.07, respectively) after adjusting for traditional risk factors. Severe psoriasis and PsA prescribed a DMARD had an elevated but not statistically significant risk for VTE. Findings were similar for DVT. The age-and-sex-adjusted risk of PE was elevated in RA, severe psoriasis and PsA patients prescribed a DMARD. Conclusion: While systemic inflammation is a risk factor for VTE, the risk of VTE compared with controls is different among patients with three different inflammatory disorders: RA, PsA, and psoriasis.

BACKGROUND: Patient-Oriented Eczema Measure (POEM) is the preferred patient-reported outcome (PRO) for assessing symptoms of atopic dermatitis (AD). Dermatology Life Quality Index (DLQI) is commonly used to assess the burden of skin disease. Previous severity strata were developed for POEM and DLQI in clinical cohorts, which may be biased toward more severe disease. Severity strata were not previously examined in population-based cohorts. Patient-Oriented Scoring AD (PO-SCORAD) is another commonly used PRO for assessing AD symptoms; however, severity strata are not established. OBJECTIVE: We sought to confirm previously developed strata for POEM and DLQI, and to develop strata for the PO-SCORAD in a population-based cohort of adults with AD. METHODS: A cross-sectional, population-based study of 8,217 adults was performed using a structured questionnaire. A diagnosis of AD was determined using modified UK Diagnostic Criteria for AD (nâ¯=â¯602). AD severity was assessed using self-reported global AD severity (anchoring question), POEM, PO-SCORAD, and DLQI. Strata were selected using an anchoring approach based on patient-reported disease severity. RESULTS: We confirmed the existing strata for DLQI (mildâ¯=â¯0-5, moderateâ¯=â¯6-10, severeâ¯=â¯11-30) (kappaâ¯=â¯0.446). However, the preferred strata for POEM was mildâ¯=â¯0-7, moderateâ¯=â¯8-19, and severeâ¯=â¯20-28 (kappaâ¯=â¯0.409) and PO-SCORAD was mildâ¯=â¯1-27, moderateâ¯=â¯28-56, severeâ¯=â¯57-104 (kappaâ¯=â¯0.444). CONCLUSION: Existing strata for DLQI performed well in a population-based cohort of adult AD. The optimal severity strata for the POEM in our AD population varies slightly from those previously published for AD. This may suggest that different strata may be optimal in different study settings and cohorts. Finally, we proposed new strata for PO-SCORAD in adult AD.

BACKGROUND: Atopic dermatitis (AD) has been associated with multiple comorbid extracutaneous and systemic disorders. The relation between AD severity and disease comorbidities is complex and not fully understood. OBJECTIVE: To determine the complex relation between AD severity and comorbidities. METHODS: A cross-sectional US population-based study of 8,217 adults who were participants in a nationally representative internet health panel was performed using a structured questionnaire. A diagnosis of AD was determined using modified United Kingdom Working Party Criteria for AD (nâ¯=â¯602). AD severity was assessed using Patient-Oriented Scoring AD, Patient-Oriented Eczema Measure, Dermatology Life Quality Index, and self-reported global AD severity. Logistic regression and structural equation models were used to explore associations of AD with self-reported allergic, cardiometabolic, anxiety and depression, and autoimmune disease. RESULTS: In multivariable regression models controlling for sociodemographics, AD was associated with higher odds of asthma (adjusted odds ratio [OR] 2.09, 95% confidence interval [CI] 1.71-2.55), hay fever (OR 4.31, 95% CI 3.27-5.69), food allergy (OR 2.07, 95% CI 1.54-2.77), anxiety and depression (OR 2.34, 95% CI 1.91-2.87), autoimmune disease (OR 3.05, 95% CI 2.31-4.03), obesity (OR 1.37, 95% CI 1.13-1.67), diabetes (OR 1.52, 95% CI 1.16-1.99), high blood pressure (OR 1.46, 95% CI 1.18-1.80), and heart disease (OR 1.94, 95% CI 1.40-2.70) compared with controls (P < .01 for all). All these associations were significant in mild and/or moderate disease, with even stronger effects in severe AD. Results of structural equation models showed direct effects of moderate to severe AD on food allergy, anxiety and depression, and diabetes, direct and indirect effects on obesity, and indirect effects on high blood pressure and heart disease. CONCLUSION: There is a strong relation of AD severity to allergic, autoimmune, and cardiovascular comorbidities.

BACKGROUND: Atopic dermatitis (AD) is associated with skin lesions, multiple symptoms, and effect of quality of life, all of which factor into disease severity. Self-reported global AD severity may be a valid severity assessment for epidemiologic research. OBJECTIVE: To validate self-reported global AD severity in a representative cohort of adults with AD. METHODS: Preliminary probing-cognitive interviews were performed (nâ¯=â¯8). Next, a cross-sectional US population-based survey study of adults with AD was performed. AD was diagnosed using an adap/tation of the UK Working Party criteria (nâ¯=â¯602). AD severity was assessed using self-reported global AD severity (mild, moderate, severe), Patient-Oriented Scoring AD (PO-SCORAD), Patient-Oriented Eczema Measure (POEM), Numeric Rating Scale (NRS)-itch, NRS-sleep, NRS-pain, and Hospital Anxiety and Depression Scale (HADS). RESULTS: Self-reported global AD severity had good content validity. Self-reported global AD severity had strong correlations with PO-SCORAD (Spearman correlation ρâ¯=â¯0.61) and objective PO-SCORAD (ρâ¯=â¯0.61); moderate correlations with POEM (ρâ¯=â¯0.54), NRS-itch (ρâ¯=â¯0.44), NRS-pain (ρâ¯=â¯0.46), and HADS (ρâ¯=â¯0.41); and weak correlation with NRS-sleep (ρâ¯=â¯.32) (P < .001 for all). Consistent and significant correlations were observed in stratified analyses by age, sex, race/ethnicity, and level of education. There were stepwise increases of PO-SCORAD, NRS-itch, NRS-sleep, NRS-pain, POEM, and HADS with increasing self-reported global AD severity (Kruskal-Wallis test, P < .01). There was weak-moderate concordance between self-reported AD severity and established severity strata for PO-SCORAD (ρâ¯=â¯0.44), NRS-itch (ρâ¯=â¯0.30), and POEM (ρâ¯=â¯0.43). Rather, self-reported global AD severity was best predicted by a combination of PO-SCORAD, POEM, NRS-itch, NRS-pain, and HADS. No differential item reporting was found by age, sex, or race/ethnicity. CONCLUSION: Self-reported AD severity simultaneously assesses multiple AD constructs and appears to be sufficiently valid for assessing AD severity in clinical and epidemiologic studies.

BACKGROUND: The patient burden and quality of life (QOL) impact of atopic dermatitis (AD) in the United States population is not well established. OBJECTIVE: To elucidate the patient burden of AD in the US population. METHODS: A cross-sectional, population-based study of 602 adults was performed. Atopic dermatitis was determined using modified UK Diagnostic Criteria for AD. Its severity was assessed using self-reported global AD severity, Patient-Oriented Eczema Measure (POEM), Patient-Oriented Scoring AD (PO-SCORAD), PO-SCORAD-itch, and sleep. Quality of life was assessed using short-form (SF-)12 mental and physical health scores and Dermatology Life Quality Index (DLQI). RESULTS: Adults with AD reported higher proportions of having only fair/poor overall health (25.8% vs. 15.8%), being somewhat/very dissatisfied with life (16.7% vs 11.4%), lower weighted mean (standard deviation [SD]) SF-12 mental (45.9 [9.9] vs 50.9 [9.2]) and physical health subscores (53.0 [2.5] vs 53.5 [2.3]) and higher DLQI (4.9 [6.5] vs 1.1 [2.8]). In multivariable regression models adjusting for sociodemographics and multiple comorbid health disorders, significant stepwise decreases by AD severity (self-reported, POEM, PO-SCORAD) of overall health, life satisfaction, SF-12 mental health, and increases of DLQI scores were seen. The SF-12 physical health scores were only associated with moderate AD. Concurrently, severe PO-SCORAD, POEM, or PO-SCORAD-itch was associated with very low mean SF-12 mental health (34.7) and high DLQI scores (24.7). Atopic dermatitis commonly limited lifestyle (51.3%), led to avoidance of social interaction (39.1%), and impacted activities (43.3%). The most burdensome AD symptoms were itch (54.4%), excessive dryness/scaling (19.6%), and red/inflamed skin (7.2%). CONCLUSION: These data support the heavy burden that AD places on patients, particularly those with moderate and severe AD.
