RESUMEN
BACKGROUND: Topical corticosteroid phobia is associated with poor treatment adherence and is common among patients with skin disease. Knowledge about corticosteroid phobia and treatment adherence among patients with chronic hand eczema (CHE) is limited. OBJECTIVES: Investigate patient-reported outcomes regarding topical corticosteroids (TCS), and their impact on treatment adherence in CHE patients. METHODS: CHE patients from the Danish Skin Cohort answered a questionnaire including the Topical Corticosteroid Phobia (TOPICOP) scale and Medication Adherence Report Scale (MARS-5). Response rate was 69.2%. RESULTS: Of 927 with CHE, 75.5% totally or almost agreed that TCS damage the skin, 48.9% totally or almost agreed that TCS would affect their future health and 36.3% reported some degree of fear of TCS even though they were unaware of any TCS-associated risks. Most patients (77.9%) always or often stop treatment as soon as possible while 54.8% always or often wait as long as possible before starting treatment. Overall, 38.8% reported that they had taken less medicine than prescribed and 54.0% had stopped treatment throughout a period. Treatment adherence decreased with increasing corticosteroid phobia (p=0.004). LIMITATIONS: TOPICOP has not been validated in CHE patients. CONCLUSIONS: Corticosteroid phobia is common among CHE patients and negatively associated with treatment adherence.
RESUMEN
BACKGROUND: Flare patterns are not routinely considered in the severity classification or in clinical decision-making of atopic dermatitis (AD), but frequent or severe flares may contribute considerably to the disease burden. OBJECTIVES: To characterize patients with AD in relation to their flare pattern and compare flare patterns to disease severity, life quality and treatment satisfaction. METHODS: Patients with AD from the Danish Skin Cohort were included if they had active AD with and available data on number of flare-ups within the last 12 months. Categorical variables were presented as frequencies and percentages, whereas numerical variables were presented as median and interquartile ranges (IQR). Between-group differences were tested with chi-squared tests. RESULTS: A total of 1557 patients were included, with 57 reporting 0 flares, 698 (1-5 flares), 324 (6-10 flares) and 478 reporting >10 flares during the past 12 months. Both the severity measured by PO-SCORAD and the impairment of life quality measured by DLQI were higher among patients with more flares (median [IQR] PO-SCORAD: 13.0 [5.6-22.3], 29.7 [20.8-40.6], 36.3 [26.7-47.6]and 42.9 [30.7-55.6], respectively for the four flares strata, and median [IQR] DLQI: 1.0 [0.0-2.0], 3.0 [1.0-7.0], 4.0 [1.8-9.0] and 7.0 [3.0-11.0]). Satisfaction with the current treatment was generally higher among patients with no flares. However, 36.8%, 24.6% and 23.7% of patients with 1-5, 6-10 and >10 flares reported being extremely or very satisfied with their current treatment. CONCLUSIONS: Patients with many flares often report a higher severity and impairment of life quality compared to patients with fewer flares. Information on flaring could benefit treatment decisions, thereby decreasing undertreatment of patients with mild AD but severe flaring.
RESUMEN
Background: There is currently limited insight into the broader impact of atopic dermatitis (AD) on mental health. Although studies indicate that AD patients may experience fatigue, no study has so far examined fatigue in more granular detail, for example, occurrence of general fatigue, physical fatigue, reduced activity, reduced motivation, and mental fatigue, or correlated fatigue measures with AD severity and symptoms intensity. Objectives: To examine fatigue subtypes and their prevalence in adults with AD, as well as their possible association with AD severity. Methods: A survey was conducted in adults with AD who had been managed in a hospital setting. The Patient-Oriented SCORing Atopic Dermatitis was used to determine AD severity. Patient reported outcomes, including multidimensional fatigue inventory, were included. Results: Data from 2729 adults with AD were analyzed. The total and individual fatigue scores increased consistently with lower socioeconomic scores, higher AD severity, Dermatology Life Quality Index, itch, pain, and sleep scores. Increased fatigue scores were associated with AD severity in adjusted analyses. Conclusions: Among adults with AD, fatigue scores increased with disease severity as well as intensity of AD symptoms. Fatigue is a hitherto underappreciated symptom of AD that clinicians should be cognizant about.

BACKGROUND: Use of Janus kinase 1 inhibitors in moderate-to-severe atopic dermatitis (AD) is associated with incident acne in adolescent and adults that is mostly mild, transient and treatable. There is a need for more knowledge about the risk and severity of acne in patients with AD. OBJECTIVES: To examine the prevalence, incidence and risk of acne in adolescents and adults with AD using nationwide prescription data. METHODS: A matched cohort study of 6600 adults with AD and 66 000 controls was conducted using routinely and prospectively collected nationwide administrative data. Adjusted hazard ratios (HR) are reported with 95% confidence intervals (CIs). RESULTS: The 12-month prevalence of acne was 3.7% in the general population and 3.9% among AD patients. The incidence rate of acne was highest among 12- to 18-year-old AD patients, and overall slightly higher in women with AD compared with males. The overall risk in patients with AD was similar with that of the general population (HR 0.96; 95% CI 0.88-1.06), whereas the risk of being treated for severe acne was reduced in AD patients (HR 0.59; 95% CI 0.47-0.73) and mainly among adolescents and young adults. The HR of acne increased with age reaching 1.41 (95% CI 1.07-1.87) for ages 30-39 years, and 2.07 (95% CI 1.42-3.03) for patients ≥40 years compared with controls. CONCLUSIONS: The risk and severity of acne in AD patients change with age and sex, which may be used for the risk assessment of acne following treatment with Janus kinase 1 inhibitors.

IMPORTANCE: Questionnaire studies are important for estimating the prevalence of psoriasis and atopic dermatitis; however, validity among the adult population remains an important concern. OBJECTIVE: To examine the test-retest accuracy of questionnaires for measuring psoriasis and atopic dermatitis prevalence in an adult population. DESIGN, SETTING, AND PARTICIPANTS: This nationwide population-based cohort study administered questionnaires on psoriasis and atopic dermatitis to the same 2333 and 2312 randomly selected adults (≥18 years) in Denmark, respectively, at 2 different time points from May 15, 2018, to November 20, 2020. Data were analyzed from January 10 to January 28, 2021. To reduce the risk of participation bias, potential respondents were given information on the research project only after agreeing to participate. EXPOSURES: Participants were asked identical questions on psoriasis and atopic dermatitis in 2018 and in 2020. Responses were linked at the individual-level. MAIN OUTCOMES AND MEASURES: The test-retest reliability (expressed by Cohen κ). RESULTS: The psoriasis questionnaire was completed by 2333 (mean [SD] age, 55.1 [16.2] years; 1338 [57.4%] women) participants in 2018 and in 2020. The atopic dermatitis questionnaire was completed by 2312 (mean [SD] age, 55.0 [16.2] years; 1326 [57.4%] women) participants in 2018 and in 2020. Among participants reporting a history of psoriasis, agreement between individual responses was high (κ = 0.7558); however, among those reporting a history of atopic dermatitis, agreement was low (κ = 0.4395). For psoriasis, prevalence changed from 7.8% to 8.0%; for atopic dermatitis, from 8.2% to 7.6%. Of participants who in 2018 reported dermatologist-diagnosed atopic dermatitis, 36.9% claimed in the 2020 questionnaire that they had never had atopic dermatitis. Analyses revealed substantial agreement for psoriasis responses across all age strata; for atopic dermatitis responses, the κ declined with increasing age, to 0.2613 for participants 65 or older. CONCLUSIONS AND RELEVANCE: This cohort study found considerable agreement between responses over time when participants were asked about a history of psoriasis. When asked about a history of atopic dermatitis, responses over time were inconsistent. This inconsistency suggests that questionnaires on a history of atopic dermatitis will confer considerable risk of bias and misclassification.
