Chong YY, Kwan JYM, Yau PT, Cheng HY, Chien WT. Roles of Parental Psychological Flexibility, Self-Compassion, and Self-Efficacy in Affecting Mental Health and Quality of Life in Parents of Children with Eczema. Healthcare (Basel) 2023; 11:2708. [PMID: 37893783 PMCID: PMC10606052 DOI: 10.3390/healthcare11202708] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Revised: 10/02/2023] [Accepted: 10/07/2023] [Indexed: 10/29/2023] Open
Abstract
Parents of young children with eczema often experience adverse mental health consequences, including depression, anxiety, stress, and a reduced health-related quality of life (HRQoL), due to the unpredictable nature of flare-ups and exacerbations. This study investigated the roles of psychological flexibility, self-compassion, and self-efficacy in fostering parental mental health outcomes and HRQoL while caring for children diagnosed with eczema. Baseline data from an ongoing clinical trial examining the effects of a family acceptance-and-commitment-therapy-based eczema management program (FACT-EMP) on parent-child dyads affected by eczema (N = 110 dyads, 75.5% mothers; 66.4% boys) were analyzed using adjusted hierarchical regression analyses. The findings indicate that psychological inflexibility was significantly associated with symptoms of anxiety, depression, stress, and HRQoL. Self-compassion was significantly linked to all assessed mental health outcomes, whereas self-efficacy showed a significant association only with symptoms of depression. These results underscore the significance of promoting parental psychological flexibility and self-compassion through acceptance and commitment therapy and compassion-based approaches to enhance mental health and quality of life while managing children's eczema.

Abstract
Background Emollients are recommended for children with eczema (atopic eczema/dermatitis). A lack of head-to-head comparisons of the effectiveness and acceptability of the different types of emollients has resulted in a 'trial and error' approach to prescribing. Objective To compare the effectiveness and acceptability of four commonly used types of emollients for the treatment of childhood eczema. Design Four group, parallel, individually randomised, superiority randomised clinical trials with a nested qualitative study, completed in 2021. A purposeful sample of parents/children was interviewed at ≈ 4 and ≈ 16 weeks. Setting Primary care (78 general practitioner surgeries) in England. Participants Children aged between 6 months and 12 years with eczema, of at least mild severity, and with no known sensitivity to the study emollients or their constituents. Interventions Study emollients sharing the same characteristics in the four types of lotion, cream, gel or ointment, alongside usual care, and allocated using a web-based randomisation system. Participants were unmasked and the researcher assessing the Eczema Area Severity Index scores was masked. Main outcome measures The primary outcome was Patient-Oriented Eczema Measure scores over 16 weeks. The secondary outcomes were Patient-Oriented Eczema Measure scores over 52 weeks, Eczema Area Severity Index score at 16 weeks, quality of life (Atopic Dermatitis Quality of Life, Child Health Utility-9 Dimensions and EuroQol-5 Dimensions, five-level version, scores), Dermatitis Family Impact and satisfaction levels at 16 weeks. Results A total of 550 children were randomised to receive lotion (analysed for primary outcome 131/allocated 137), cream (137/140), gel (130/135) or ointment (126/138). At baseline, 86.0% of participants were white and 46.4% were female. The median (interquartile range) age was 4 (2-8) years and the median Patient-Oriented Eczema Measure score was 9.3 (SD 5.5). There was no evidence of a difference in mean Patient-Oriented Eczema Measure scores over the first 16 weeks between emollient types (global p = 0.765): adjusted Patient-Oriented Eczema Measure pairwise differences - cream-lotion 0.42 (95% confidence interval -0.48 to 1.32), gel-lotion 0.17 (95% confidence interval -0.75 to 1.09), ointment-lotion -0.01 (95% confidence interval -0.93 to 0.91), gel-cream -0.25 (95% confidence interval -1.15 to 0.65), ointment-cream -0.43 (95% confidence interval -1.34 to 0.48) and ointment-gel -0.18 (95% confidence interval -1.11 to 0.75). There was no effect modification by parent expectation, age, disease severity or the application of UK diagnostic criteria, and no differences between groups in any of the secondary outcomes. Median weekly use of allocated emollient, non-allocated emollient and topical corticosteroids was similar across groups. Overall satisfaction was highest for lotions and gels. There was no difference in the number of adverse reactions and there were no significant adverse events. In the nested qualitative study (n = 44 parents, n = 25 children), opinions about the acceptability of creams and ointments varied most, yet problems with all types were reported. Effectiveness may be favoured over acceptability. Parents preferred pumps and bottles over tubs and reported improved knowledge about, and use of, emollients as a result of taking part in the trial. Limitations Parents and clinicians were unmasked to allocation. The findings may not apply to non-study emollients of the same type or to children from more ethnically diverse backgrounds. Conclusions The four emollient types were equally effective. Satisfaction with the same emollient types varies, with different parents/children favouring different ones. Users need to be able to choose from a range of emollient types to find one that suits them. Future work Future work could focus on how best to support shared decision-making of different emollient types and evaluations of other paraffin-based, non-paraffin and 'novel' emollients.

Abstract
BACKGROUND It is unclear if ambient temperature changes affect eczema. It is also unclear if people with worse disease are more susceptible to weather-related flares, or specific types of emollient offer protection. OBJECTIVES To investigate the effect of short-term temperature variations on eczema symptoms in children. METHODS Data from a UK cohort of 519 children with eczema were combined with data from the Hadley Centre's Integrated Surface Database. Hot and cold weeks were defined by average regional temperature > 75th or < 25th percentile, January 2018 to February 2020. Eczema flares were defined as ≥ 3-point change in Patient-Oriented Eczema Measure (POEM). Random-effects logistic regression models were used to estimate the odds ratios of flares in hot and cold weeks (reference group: temperate weeks). RESULTS The baseline mean age was 4.9 years (SD 3.2) and the POEM score was 9.2 (SD 5.5). From the 519 participants, there were 6796 consecutively paired POEMs and 1082 flares. Seasonal variation in POEM scores was observed, suggesting symptoms worsening in winter and improving in summer. Odds ratios of flares were: 1.15 [95% confidence interval (CI) 0.96-1.39, P = 0.14] in cold weeks and 0.85 (95% CI 0.72-1.00, P = 0.05) in hot weeks. The likelihood ratio test showed no evidence of this differing by disease severity (P = 0.53) or emollient type used (P = 0.55). CONCLUSIONS Our findings are consistent with previous studies demonstrating either improvements in eczema symptoms or reduced flares in hot weather. Worse disease and different emollient types did not increase susceptibility or provide protection against temperature changes. Further work should investigate the role of sunlight, humidity, pollution and other environmental factors.

Abstract
This is the English version of the Clinical Practice Guidelines for the Management of Atopic Dermatitis 2021. Atopic dermatitis (AD) is a disease characterized by relapsing eczema with pruritus as a primary lesion. In Japan, from the perspective of evidence-based medicine, the current strategies for the treatment of AD consist of three primary measures: (i) use of topical corticosteroids, tacrolimus ointment, and delgocitinib ointment as the main treatment of the inflammation; (ii) topical application of emollients to treat the cutaneous barrier dysfunction; and (iii) avoidance of apparent exacerbating factors, psychological counseling, and advice about daily life. In the present revised guidelines, descriptions of three new drugs, namely, dupilumab, delgocitinib, and baricitinib, have been added. The guidelines present recommendations to review clinical research articles, evaluate the balance between the advantages and disadvantages of medical activities, and optimize medical activity-related patient outcomes with respect to several important points requiring decision-making in clinical practice.

Abstract
BACKGROUND To our knowledge, there are no trials comparing emollients commonly used for childhood eczema. We aimed to compare the clinical effectiveness and safety of the four main emollient types: lotions, creams, gels, and ointments. METHODS We did a pragmatic, individually randomised, parallel group, phase 4 superiority trial in 77 general practice surgeries in England. Children aged between 6 months and 12 years with eczema (Patient Orientated Eczema Measure [POEM] score >2) were randomly assigned (1:1:1:1; stratified by centre and minimised by baseline POEM score and age, using a web-based system) to lotions, creams, gels, or ointments. Clinicians and parents were unmasked. The initial emollient prescription was for 500 g or 500 mL, to be applied twice daily and as required. Subsequent prescriptions were determined by the family. The primary outcome was parent-reported eczema severity over 16 weeks (weekly POEM), with analysis as randomly assigned regardless of adherence, adjusting for baseline and stratification variables. Safety was assessed in all randomly assigned participants. This trial was registered with the ISRCTN registry, ISRCTN84540529. FINDINGS Between Jan 19, 2018, and Oct 31, 2019, 12 417 children were assessed for eligibility, 550 of whom were randomly assigned to a treatment group (137 to lotion, 140 to cream, 135 to gel, and 138 to ointment). The numbers of participants who contributed at least two POEM scores and were included in the primary analysis were 131 in the lotion group, 137 in the cream group, 130 in the gel group, and 126 in the ointment group. Baseline median age was 4 years (IQR 2-8); 255 (46%) participants were girls, 295 (54%) were boys; 473 (86%) participants were White; and the mean POEM score was 9·3 (SD 5·5). There was no difference in eczema severity between emollient types over 16 weeks (global p value=0·77), with adjusted POEM pairwise differences of: cream versus lotion 0·42 (95% CI -0·48 to 1·32), gel versus lotion 0·17 (-0·75 to 1·09), ointment versus lotion -0·01 (-0·93 to 0·91), gel versus cream -0·25 (-1·15 to 0·65), ointment versus cream -0·43 (-1·34 to 0·48), and ointment versus gel -0·18 (-1·11 to 0·75). This result remained unchanged following multiple imputation, sensitivity, and subgroup analyses. The total number of adverse events did not significantly differ between the treatment groups (lotions 49 [36%], creams 54 [39%], gels 54 [40%], and ointments 48 [35%]; p=0·79), although stinging was less common with ointments (12 [9%] of 138 participants) than lotions (28 [20%] of 137), creams (24 [17%] of 140), or gels (25 [19%] of 135). INTERPRETATION We found no difference in effectiveness between the four main types of emollients for childhood eczema. Users need to be able to choose from a range of emollients to find one that they are more likely to use effectively. FUNDING National Institute for Health and Care Research.

Interpretation of a Quantitative Diagnosis Model of Traditional Chinese Medicine Syndromes Based on Computer Adaptive Testing. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:3203158. [PMID: 35815272 PMCID: PMC9262526 DOI: 10.1155/2022/3203158] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Revised: 03/06/2022] [Accepted: 06/09/2022] [Indexed: 11/24/2022]
Abstract
Objectives The aim of this study is to interpret a quantitative diagnosis model of traditional Chinese medicine (TCM) syndromes based on computer adaptive testing (CAT), from the perspective of both patients and clinicians. Methods In this cross-sectional study, patients with postprandial distress syndrome completed the CAT model of TCM syndromes and the Chinese version of the Quality of Life Questionnaire for Functional Digestive Disorders (Chin-FDDQL); the clinicians' diagnosis was concurrently recorded. The patients completed this questionnaire again after 14 ± 2 days. The kappa test and paired chi-square test were used to evaluate the consistency between the CAT model and clinical diagnosis. Minimal clinically important differences (MCID) of the Chin-FDDQL scores were used to assess clinical efficacy from the patients' perspective. Logistic regression was used to examine the association between changes in the CAT model syndrome domain scores and changes in clinical outcomes. Results Changes in the CAT model syndrome domain scores may affect the clinical outcomes of patients with the total scores of Chin-FDDQL (all P < 0.05). There was a correlation between changes in the CAT model syndrome domain scores and the patients' clinical outcomes. Different syndrome elements had different effects on various Chin-FDDQL domains, which was consistent with the theory of TCM. Conclusions This study proposes a method for the clinical interpretation of the CAT model of TCM syndromes, including evidence derived from the application. It may provide a reference for future interpretation of other CAT models.

Abstract
BACKGROUND Atopic dermatitis (AD) is the most common chronic inflammatory skin condition in childhood. Most (50-60%) children with AD report sleep disturbance, which is secondary to itch, dry skin, inflammation, and abnormal circadian rhythm. Sleep is essential for brain development, learning, and growth. Sleep disruption in early life is associated with cognitive and psychological dysfunction in later life. The aim of this study is to describe in detail the sleep architecture of infants with early-onset atopic dermatitis (AD), compared to controls, by using EEG polysomnography, sleep actigraphy, and parental reporting. METHODS This observational study will recruit six- to eight-month old infants with moderate to severe AD and age-matched control infants who do not have AD. At six-eight months diurnal sleep electroencephalography and polysomnography will be performed in our research center. Nocturnal sleep actigraphy will be performed at home for five consecutive nights at six-eight months and 12 months. Between six and 12 months, monthly questionnaires will capture data on quantitative sleep and parental sleep. Skin barrier and immune profiles will be captured at six-eight and 12 months. AD will be assessed using standardized severity assessment tools and treated according to protocol. A neurodevelopmental assessment will be performed at 18 months to assess cognition and behaviour. An estimated sample size of 50 participants in each group is required to power the primary outcome of disturbed macrostructure of sleep and secondary outcomes of disturbed microstructure of sleep, and disturbed parental sleep, assuming an attrition rate of 60%. Potential confounding factors which will be controlled for in the data analysis will include parental educational level, parental depression, feeding practice, and number of siblings. DISCUSSION This study will provide a rich analysis of sleep in infants with AD in the first year of life using detailed electroencephalography, novel actigraphy techniques, and longitudinal parent-reported data. It may provide guidance on the optimal treatment of AD to prevent or reduce sleep disruption. TRIAL REGISTRATION clinicaltrials.gov NCT05031754 , retrospectively registered on September 2nd, 2021.

Differences in Psychometric Properties of Clinician- and Patient-Reported Outcome Measures for Atopic Dermatitis by Race and Skin Tone: A Systematic Review. J Invest Dermatol 2022; 142:364-381. [PMID: 34352262 PMCID: PMC8792149 DOI: 10.1016/j.jid.2021.06.033] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Revised: 06/22/2021] [Accepted: 06/28/2021] [Indexed: 02/03/2023]
Abstract
The psychometric validity and reliability of widely used atopic dermatitis (AD) outcome measures across different races and ethnicities are unclear. We describe the rates of reporting race, ethnicity, and skin tone in studies testing the psychometric properties of AD outcome measures and compare the psychometric analyses across race, ethnicity, and skin tone. We systematically reviewed MEDLINE and EMBASE for studies reporting psychometric properties of clinician-reported or patient-reported outcome measures in AD (International Prospective Register of Systematic Reviews: CRD42021239614). Overall, 16,100 nonduplicate articles were screened; 165 met inclusion criteria. Race and/or ethnicity were reported in 55 (33.3%) studies; of those, race was assessed by self-report in 10 studies (6.1%) or was unspecified in 45 (27.3%). A total of 16 studies (9.7%) evaluated psychometric property differences by race, and only five (4.4%) of those did not recognize it as a limitation. Properties assessed across race, ethnicity, or skin tone were differential item functioning, convergent validity feasibility, inter-rater reliability, intrarater reliability, test‒retest reliability, and known-groups validity. Multiple instruments demonstrated performance differences across ethnoracial groups. This review highlights the paucity of race/ethnicity consideration for psychometric property testing in AD outcome measurement instruments. More AD outcomes instruments should be validated in diverse populations.

Abstract
Background Interleukin (IL)‐31 affects the inflammatory response, is involved in epidermal barrier disruption in atopic dermatitis (AD) and plays a key role in pruritus. Nemolizumab, a humanized monoclonal antibody against IL‐31 receptor A, reduced pruritus in patients with AD after a 16‐week administration period. Objectives To examine the long‐term effectiveness and safety of nemolizumab in patients aged ≥ 13 years with AD and inadequately controlled moderate‐to‐severe pruritus. Methods In two long‐term phase III studies, nemolizumab 60 mg every 4 weeks (Q4W) was administered subcutaneously, concomitantly with topical treatments. Study‐JP01 patients received double‐blind nemolizumab or placebo for 16 weeks, and then entered a 52‐week extension period in which all patients received nemolizumab (nemolizumab/nemolizumab and placebo/nemolizumab groups). Study‐JP02 patients received nemolizumab for 52 weeks. Both studies included an 8‐week follow‐up period. Results Study‐JP01 nemolizumab/nemolizumab and placebo/nemolizumab, and Study‐JP02 nemolizumab groups comprised 143, 72 and 88 patients, respectively. In the nemolizumab/nemolizumab group, there were clinically meaningful improvements from the start of treatment to week 68 in the pruritus visual analogue scale (66% decrease) and Eczema Area and Severity Index (78% decrease). Quality of life (QoL) indicators improved after the first nemolizumab dose; improvements were maintained during the follow‐up period. The long‐term safety profile was consistent with previous studies, with no unexpected late‐onset adverse events. Conclusions Nemolizumab 60 mg Q4W with concomitant topical treatments in patients with AD and inadequately controlled moderate‐to‐severe pruritus produced a continuous improvement in pruritus, signs of AD, and QoL for up to 68 weeks, with a favourable safety profile.

Abstract
Background The Patient‐Oriented Eczema Measure (POEM) is the core outcome instrument recommended for measuring patient‐reported atopic eczema symptoms in clinical trials. To ensure that the statistical significance of clinical trial results is meaningful, trials are often designed by specifying the target difference in the primary outcome as part of the sample size calculation. One method used to specify the target difference is a score that corresponds to a standardized effect size. Objectives to assess how the standardized effect size of POEM scores vary across age, gender, ethnicity and disease severity. Methods This study combined data from five UK‐based randomized clinical trials of eczema treatments in order to assess differences in self‐reported eczema symptoms (POEM) corresponding to a standardized effect size (0.5 SD of baseline POEM scores) across age, gender, ethnicity and disease severity. Results POEM scores corresponding to 0.5 SD(baseline) were remarkably consistent across participants of varying ages, gender, ethnicity and disease severity from datasets of five UK trials in children (range 2.99–3.45). Conclusions This study provides information that can support those designing clinical trials to determine their sample size and can aid individuals interpreting trial results. Further exploration of differences in populations beyond the United Kingdom is needed.

Abstract
INTRODUCTION The Patient-Oriented Eczema Measure (POEM) assesses patient-reported severity of atopic dermatitis (AD) symptoms, whereas the Children's Dermatology Life Quality Index (CDLQI) measures how AD affects health-related quality of life (HRQoL) in children. Although the POEM and CDLQI have established thresholds for clinically meaningful within-patient change in adolescents (aged 12-17 years), there are no defined within-patient responder thresholds for clinically meaningful change in children aged 6-11 years. METHODS Data from the LIBERTY AD PEDS phase 3 randomized, double-blind, placebo-controlled trial of dupilumab in children aged 6-11 years with severe AD were used to define the threshold for within-patient meaningful change in POEM and CDLQI scores. Anchor-based methods were applied to estimate mean change in POEM and CDLQI scores from baseline to week 16, with anchors of a 1-point improvement in the Patient Global Impression of Disease (PGID) scale and an improvement in score of ''A little better'' on the Patient Global Impression of Change (PGIC) scale. The distribution-based methods, a one-half standard deviation (SD) at baseline and a standard error mean (SEM) were also used. RESULTS The mean POEM change scores associated with the anchors were a change of - 8.40 with the PGID anchor and - 6.30 with the PGIC anchor. Distribution-based estimates for POEM were one-half SD at baseline of 2.76, with a SEM of 3.32. Mean CDLQI change scores corresponding to the PGID and PGIC anchors were - 7.30 and - 6.80, respectively, while distribution-based estimates for CDLQI were a one-half SD at baseline of 3.69, with a SEM of 3.52. CONCLUSIONS In children with severe AD, an appropriate minimum threshold of clinically meaningful within-patient change was estimated as 6 points for both the POEM and CDLQI scores.

Abstract
INTRODUCTION As new topical and systemic treatments become available for atopic dermatitis (AD), there is a need to understand how treatments are being used in routine clinical practice, their comparative effectiveness and their long-term safety in diverse clinical settings. METHODS AND ANALYSIS The TARGET-DERM AD cohort is a longitudinal, observational study of patients with AD of all ages, designed to provide practical information on long-term effectiveness and safety unobtainable in traditional registration trials. Patients with physician-diagnosed AD receiving prescription treatment (topical or systemic) will be enrolled at academic and community clinical centres. Up to 3 years of retrospective medical records, 5 years of prospective medical records, and optional biological samples and patient-reported outcomes will be collected. The primary aims include characterisation of AD treatment regimens, evaluation of response to therapy, and description of adverse events. ETHICS AND DISSEMINATION TARGET-DERM has been approved by a central IRB (Copernicus Group IRB, 5000 Centregreen Way Suite 200, Cary, North Carolina 27513) as well as local and institutional IRBs. No additional Ethics Committee reviews. Results will be reviewed by a publications committee and submitted to peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT03661866, pre-results.

Abstract
BACKGROUND Atopic eczema (AE) is a common relapsing inflammatory skin disease in children which is often associated with chronicity and poor quality of life. Unlike atopic asthma, control of AE is seldom assessed in therapeutics. AIM To investigate the utility of a Traffic Light Control (TLC) system as a measurement/assessment of self-perceived eczema control. METHODS This is a prospectively study of all Chinese children (aged 6 to 18 years old) with eczema attending the paediatric dermatology clinic of a tertiary hospital from Jan to June 2020. Eczema control, eczema severity, quality of life and biophysical skin condition of consecutive patients at the paediatric dermatology clinic of a teaching hospital were evaluated with the validated Chinese versions of Depressive, Anxiety, Stress Scales (DASS-21), Patient Oriented Eczema Measure (POEM), transepidermal water loss (TEWL), and stratum corneum skin hydration (SH), respectively. With a visual TLC analogy, patients were asked if their eczema is under control (green light), worsening (yellow) or in flare-up (red light). RESULTS Among AE patients (n = 36), self-perceived TLC as green (under control), amber (worsening) and red (flare up) reflected acute and chronic severity (SCORAD, NESS, POEM) and quality of life (CDLQI) (p< 0.0001), but not SH, TEWL or Depression, anxiety and stress. CONCLUSIONS Eczema control can be semi-quantified with a child-friendly TLC self-assessment system. AE patients reporting worse eczema control have worse acute and chronic eczema severity, more impairment of quality of life; but not the psychologic symptoms of depression, anxiety and stress or skin hydration or transepidermal water loss. TLC can be linked to an eczema action plan to guide patient management.

Abstract
STUDY QUESTION Is the Sexual Activity Questionnaire (SAQ) a valid tool for patients treated for symptomatic endometriosis? SUMMARY ANSWER For women having surgical treatment for endometriosis, we determined that the SAQ is a valid and responsive tool. WHAT IS KNOWN ALREADY Endometriosis adversely affects sexual quality of life. Suitable validated sexual quality of life instruments for endometriosis are lacking both in clinical practice and for research. STUDY, DESIGN, SIZE, DURATION A total of 367 women with proven endometriosis undergoing medical or surgical treatment were included in an observational study conducted between 1 January 2012 and 31 December 2014 in two French tertiary care centers. Both hospitals are reference centers for endometriosis treatment. Of these 367 women, 267 were sexually active and constituted the baseline population. PARTICPANTS/MATERIALS, SETTINGS, METHODS Women >18 years old with histological or radiological proven endometriosis, consulting for painful symptoms of at least 3 months duration, infertility, or other symptoms (bleeding, cysts) were invited to complete self-administered questionnaires before (T0) and 12 months after treatment (T1). Tests of data quality included descriptive statistics of the data, missing data levels, floor and ceiling effects, structural validity and internal consistency.The construct validity was obtained by testing presupposed relationships between previously established SAQ scores and prespecified characteristics of the patients by comparing different subgroups of patients at T0. Sensitivity to change was subsequently calculated by comparing the SAQ score between T1 and T0 overall and for different subgroups of treatment. Effect sizes (to T1) were calculated according to Cohen's method. The minimally important difference was estimated by a step-wise triangulation approach (including anchor-based method). MAIN RESULTS AND THE ROLE OF CHANCE In total, 267 sexually active patients (204 surgical and 63 medical treatment) completed the SAQ at T0 and 136 (50.9%) at T1. The SAQ score ranged from 2.0 to 28.0 (mean ± SD: 16.8 ± 5.7).The SAQ score was one-dimensional according to the scree plot with good internal consistency (Cronbach alpha = 0.78, 95% CI 0.74-0.81) and had good discriminative ability according to pain descriptors and quality of life in endometriosis. The SAQ was responsive in patients treated by surgery but the effect size was low (0.3, 95% CI (0.0-0.6), P = 0.01). The minimally important difference was determined at 2.2. LIMITATIONS, REASONS FOR CAUTION The effect size for medical treatment was non-significant. Other effect sizes were low but statistically significant. This could be explained by lower libido due to progestin intake, which was used for both surgically and medically treated patients. WIDER IMPLICATIONS OF THE FINDINGS The SAQ is easy to use, valid and effective in assessing sexual quality of life in patients with endometriosis. This patient-reported score could be used as a primary outcome for future clinical studies. The minimally important difference estimation will be useful for future research. We recommend using 2.2 for the minimally important difference of the SAQ.

Abstract
Atopic dermatitis (AD) is a disease characterized by relapsing eczema with pruritus as a primary lesion, which is frequently encountered in clinical practice. Skin barrier dysfunction leads to enhanced skin irritability to non-specific stimuli and epicutaneous sensitization. In the lesion site, a further inflammation-related reduction in skin barrier function, enhanced irritability and scratching-related stimuli deteriorate eczema, leading to vicious cycle of inflammation. The current strategies to treat AD in Japan from the perspective of evidence-based medicine consist of three primary measures: (i) the use of topical corticosteroids and tacrolimus ointment as the main treatment for the inflammation; (ii) topical application of emollients to treat the cutaneous barrier dysfunction; and (iii) avoidance of apparent exacerbating factors, psychological counseling and advice about daily life. The guidelines present recommendations to review clinical research articles, evaluate the balance between the advantages and disadvantages of medical activities, and optimize medical activity-related patient outcomes with respect to several important points requiring decision-making in clinical practice.

Abstract
Background: Atopic dermatitis (AD) is a chronic inflammatory disease associated with pruritus and sleep loss. Pine-tar has long been used for various chronic skin conditions in which its polycyclic aromatic hydrocarbon (PAH) component is anti-inflammatory and its resin acids antiseptic. The null hypothesis of this trial is that there is no difference in clinical efficacy between a pine-tar product and its vehicle for AD.Methods: A 3-month, investigator-blinded, crossover, randomized control trial (RCT) was conducted in which each patient was assigned to bathing with pine-tar bath oil for one month and vehicle bath oil for another, with a washout period of 1-month in-between. Acceptability and efficacy of the bath products were measured. Disease severity scores (scoring atopic dermatitis (SCORAD) and patient-oriented eczema measure (POEM), quality of life questionnaires, noninvasive skin biophysiological measurements, blood IgE levels, and Staphylococcus aureus (SA) colonization status were assessed before and following bathing.Results: Significant improvements were found in total SCORAD (p = .030), POEM (p = .004), SA colonization status (p = .002), and log-transformed IgE level (p = .009) among patients who bathed with pine-tar in the overall RCT study using intention-to-treat analysis. For per protocol analysis, significant improvements were found in total SCORAD (p = .024), objective SCORAD (p = .011), extent (p = .014), intensity (p = .032), pruritus (p = .047), POEM (p = .044), SA colonization status (p = .035), and log-transformed IgE level (p = .028). Acceptability to both bath-oils was good, and no product-related serious adverse events were recorded.Conclusions: Bathing with pine-tar is an efficacious and recommendable adjuvant practice for AD patients. Disease improvement is associated with reduction of SA and IgE.

Background Crisaborole ointment, 2%, is a nonsteroidal phosphodiesterase 4 inhibitor for the treatment of mild-to-moderate atopic dermatitis (AD). Objectives The aim of this study was to evaluate the safety, effectiveness, and pharmacokinetics (PK) of crisaborole in infants aged 3 to < 24 months with mild-to-moderate AD in an open-label study. Methods Infants (3 to < 24 months) with Investigator’s Static Global Assessment (ISGA) of mild (2) or moderate (3) and percentage of treatable body surface area (%BSA) ≥ 5 received crisaborole twice daily for 28 days; a cohort with moderate AD per ISGA and %BSA ≥ 35 were included in a PK analysis. Endpoints included safety (primary), efficacy, and PK (exploratory). Results Included were 137 infants total (mean age [SD], 13.6 months [6.42]), with 21 in the PK cohort (12.7 months [6.58]). Treatment-emergent adverse events (TEAEs) were reported for 88 (64.2%) patients (98.9% rated as mild/moderate). TEAEs were considered treatment-related for 22 patients (16.1%); most frequently reported were application site pain (3.6%), application site discomfort (2.9%), and erythema (2.9%). ISGA clear/almost clear with ≥ 2-grade improvement at day 29 was achieved by 30.2% of patients. From baseline to day 29, mean percentage change in Eczema Area and Severity Index score was − 57.5%, and mean change in Patient-Oriented Eczema Measure total score was − 8.5. Crisaborole systemic exposures in infants were characterized and, based on nonlinear regression analysis, were comparable with that in patients aged ≥ 2 years. Conclusions In this open-label study, crisaborole was well tolerated and effective in infants (3 to < 24 months) with mild-to-moderate AD with systemic exposures similar to patients aged ≥ 2 years. Clinical Trial Registration NCT03356977. Electronic supplementary material The online version of this article (10.1007/s40257-020-00510-6) contains supplementary material, which is available to authorized users. Plain Language Summary Atopic dermatitis (AD) is a skin disease that causes inflamed and itchy skin. Crisaborole is an ointment that is approved to treat patients aged 2 years and older with mild-to-moderate AD. This clinical trial studied crisaborole in infants with mild-to-moderate AD who were 3 to under 24 months old. These infants were treated with crisaborole twice a day for 28 days. The trial studied crisaborole’s safety, effectiveness, and absorption into the bloodstream. In total, 137 infants were treated. Although side effects of some sort occurred in about two-thirds of patients, only 1 in 6 patients experienced side effects that were attributed to crisaborole. When these side effects did occur, these were mainly pain, discomfort, or redness where crisaborole was applied. Fewer than 1 in 25 patients experienced each side effect where crisaborole was applied. The doctors saw improvement in the AD symptoms of some patients at day 29 of the study compared to the beginning of the study. Crisaborole blood-level measurements in this age group were consistent with those seen in patients aged 2 years and older. Overall, crisaborole was considered well tolerated and effective in infants (3 to under 24 months old) with mild-to-moderate AD.

Abstract
Background Eczema control has been identified as an important outcome by key stakeholders in eczema research (including patients, carers, healthcare professionals and researchers) but no validated instruments for the domain have been identified. Objectives To develop a measurement instrument to capture a patient's perspective of eczema control that is suitable for use in eczema clinical trials. Methods Best practice for the development of a patient‐reported outcome was followed. A mixed‐methods approach was used to develop and refine a conceptual framework, generate, refine and select items and to test the distribution and construct validity of the final scale. The mixed‐methods approach involved expert panel meetings (including patient representatives, healthcare professionals and methodologists), and data collection using a focus group, cognitive interviews and an online survey with people with eczema and caregivers. Multivariable linear regression was used in the item selection process. Results Fourteen expert panel members co‐produced the instrument, with input from people with eczema and caregivers via a focus group (n = 6), cognitive interviews (n = 13) and an online survey (n = 330). The resulting instrument, Recap of atopic eczema (RECAP), is a seven‐item questionnaire that captures eczema control via self or caregiver report. The development process aimed to ensure good content validity and feasibility. Initial testing suggested no floor or ceiling effects and good construct validity. Hypothesized correlation with the Patient‐Oriented Eczema Measure was confirmed [r(258) = 0·83, P < 0·001]. Conclusions RECAP has the potential to improve reporting of eczema control in research and clinical practice. Further exploration of measurement properties is required. Linked Comment: Pattinson and Bundy. Br J Dermatol 2020; 183:418–419. What's already known about this topic? Eczema control has been identified as an important outcome by key stakeholders in eczema research (including patients, carers, healthcare professionals and researchers). Qualitative studies suggest eczema control is a multifaceted and individual experience and no instrument has been identified that captures eczema control in this way.
What does this study add? We have developed Recap of atopic eczema (RECAP), a seven‐item questionnaire to capture the experience of eczema control in all ages and eczema severities; there are two versions: a self‐reported version for adults and older children with eczema, and a caregiver‐reported version for younger children with eczema. Designed with input from people with eczema, caregivers and healthcare professionals to ensure good content validity. Initial testing of score distributions and construct validity suggests good measurement properties.
What are the clinical implications of the work? The RECAP instrument is appropriate and feasible for measuring eczema control in clinical trials and may also be useful in routine practice.

Abstract
BACKGROUND Patient-Oriented Eczema Measure (POEM) measures patient-reported symptoms in atopic dermatitis (AD). It is the recommended core outcome instrument to capture the symptoms domain in AD clinical trials. Understanding the minimal important change (MIC) in the POEM score is therefore important in both trial and clinical care settings. Previous studies have mainly evaluated MIC estimates among children in trial settings. The MIC estimate for POEM in a clinical setting is often lacking. OBJECTIVES We aim to estimate the MIC of the POEM using both distribution-based and anchor-based methods in a clinical cohort of adult eczema patients. METHODS Both distribution-based and anchor-based methods were used to calculate the MIC of the POEM in a clinical cohort of Asian adult patients attending the eczema clinic at a tertiary dermatology centre in Singapore. Scoring AD (SCORAD) was used as the disease severity anchor for the anchor-based methods. The smallest detectable change (SDC) for POEM was also calculated as the threshold for any measurement error. RESULTS There were a total of 85 adult AD patients in the cohort that contributed a total of 114 paired measurements of both POEM and SCORAD. The SDC in our study was 1.68. The MIC estimates were 3.64 and 1.46 based on 0.5 standard deviation (SD) and 0.2 SD distribution-based methods. Anchor-based methods such as the receiver operating curve and predictive modelling methods yielded MIC values of 0.50 and 1.05, respectively. CONCLUSIONS Minimal important change for POEM varied according to the methods and approaches used. Only a change of two points or more in POEM could be considered beyond any measurement errors and clinically important. This finding is consistent even in a clinical setting of Asian adults with eczema.

Abstract
INTRODUCTION The Patient-Oriented Eczema Measure (POEM) assesses patient-reported frequency of atopic dermatitis (AD) symptoms, while the Children's Dermatology Life Quality Index (CDLQI) measures the impact of skin disease on health-related quality of life (HRQoL) in children. There is currently no threshold for clinically meaningful within-person change in POEM or CDLQI scores in adolescents. Here we empirically derive within-person thresholds of meaningful within-person change in POEM and CDLQI scores in adolescents with moderate-to-severe AD. METHODS Data were used from a phase 3, randomized, double-blind, placebo-controlled trial of dupilumab in adolescents (aged ≥ 12 to < 18 years) with moderate-to-severe AD. Anchor-based methods were employed using the mean change in POEM and CDLQI scores from baseline to week 16 linked with a 1-point improvement in Patient Global Assessment of Disease (PGAD), a score of "a little better" on the Patient Global Assessment of Treatment effect (PGAT), a 50-74% improvement from baseline in the Eczema Area and Severity Index (EASI-50-74), and a 1-point improvement in Investigator's Global Assessment (IGA) score. RESULTS A mean change of - 7.8 and - 5.6 in the POEM score was associated with PGAD and PGAT anchors, respectively. EASI-50-74 was associated with a mean change in POEM score of - 8.2, while the IGA anchor was associated with a mean change of - 7.9 in POEM score. The mean changes in CDLQI score associated with PGAD and PGAT anchors were - 6.4 and - 6.6, respectively, while CDLQI mean scores changed by - 8.3 and - 8.0 for the EASI and IGA anchors, respectively. CONCLUSION In adolescents (aged ≥ 12 to < 18 years) with moderate-to-severe AD, a within-person change of 6-8 points in POEM and CDLQI scores, independently, can be considered a reasonable responder threshold for clinically meaningful change in each of the two scales, respectively.

Abstract
Atopic dermatitis (AD) is a disease characterized by relapsing eczema with pruritus as a primary lesion. The current strategies to treat AD in Japan from the perspective of evidence-based medicine consist of three primary measures: (i) the use of topical corticosteroids and tacrolimus ointment as the main treatment for the inflammation; (ii) topical application of emollients to treat the cutaneous barrier dysfunction; and (iii) avoidance of apparent exacerbating factors, psychological counseling and advice about daily life. The guidelines present recommendations to review clinical research articles, evaluate the balance between the advantages and disadvantages of medical activities, and optimize medical activity-related patient outcomes with respect to several important points requiring decision-making in clinical practice.

Abstract
INTRODUCTION Atopic dermatitis/eczema affects around 20% of children and is characterised by inflamed, dry, itchy skin. Guidelines recommend 'leave-on' emollients that are applied directly to the skin to add or trap moisture and used regularly, they can soothe, enhance the skin barrier and may prevent disease 'flares'. However, the suitability of the many different emollients varies between people and there is little evidence to help prescribers and parents and carers decide which type to try first. METHODS AND ANALYSIS Design: pragmatic, multicentre, individually randomised, parallel group superiority trial of four types of emollient (lotions, creams, gel or ointments). SETTING general practitioner surgeries in England. PARTICIPANTS children aged over 6 months and less than 12 years with mild-to-severe eczema and no known sensitivity to study emollients. INTERVENTIONS study-approved lotion, cream, gel or ointment as the only leave-on emollient for 16 weeks, with directions to apply twice daily and as required. Other treatments, such as topical corticosteroids, used as standard care. FOLLOW-UP 52 weeks. PRIMARY OUTCOME validated patient-orientated eczema measure measured weekly for 16 weeks. SECONDARY OUTCOMES eczema signs (Eczema Area Severity Index) by masked researcher, treatment use, parent satisfaction, adverse events, child and family quality of life (Atopic Dermatitis Quality of Life, Child Health Utility 9D and Dermatitis Family Impact). SAMPLE SIZE 520 participants (130 per group). ANALYSIS intention-to-treat using linear mixed models for repeated measures.Nested qualitative study: audio-recording of sample of baseline appointments and up to 60 interviews with participants at 4 and 16 weeks, interviews to be transcribed and analysed thematically. ETHICS AND DISSEMINATION Ethics approval granted by the NHS REC (South West - Central Bristol Research Ethics Committee 17/SW/0089). Findings will be presented at conferences, published in open-access peer-reviewed journals and the study website; and summaries shared with key stakeholders. TRIAL REGISTRATION NUMBER ISRCTN84540529.

Abstract
INTRODUCTION Topical corticosteroids (TCS) of different potencies are the main treatment to control atopic dermatitis (AD). The Dutch guideline on AD for general practitioners (GPs) recommends a stepwise approach in which treatment steps are tailored to the severity of the disease, starting with the lowest possible potency of TCS. However, it remains unclear whether the recommended stepwise approach is most efficient. This randomised open-label controlled trial aims to determine whether a potent TCS is more effective than a low-potency TCS in the initial treatment of children with a moderate flare-up of AD in primary care. In the observational cohort, the overall aim is to determine the frequency, burden and determinants of flare-ups of AD during follow-up. METHODS AND ANALYSIS The study is an observational cohort study with an embedded pragmatic randomised controlled, open-label trial. Eligible are patients diagnosed with AD (aged 12 weeks to 18 years) who visited the GP for AD or received repeated prescriptions for AD in the previous 12 months; follow-up of the cohort is 1 year. Children are enrolled in the trial if they have a flare-up of AD during follow-up in the cohort. Eligible children are randomised to the intervention group (with a potent TCS once daily) or to the GP guideline group (with a low potency TCS once daily). Primary outcome is the difference in average subjective disease severity over 24 weeks follow-up in the trial, measured with the patient-oriented eczema measure. As secondary outcome, the Eczema Area and Severity Index is measured. ETHICS AND DISSEMINATION This study tests the hypothesis that immediate treatment with a potent TCS during a flare-up of AD leads to faster and more efficacious results as compared with starting with a TCS with low potency with less overall use of TCS. The study protocol is approved by the Medical Ethics Committee (MEC) of the Erasmus Medical Center Rotterdam, the Netherlands (MEC-2017-328). The results of the study will be published in international peer-reviewed journals and presented at national and international conferences. TRIAL REGISTRATION NUMBER NTR: 6679; Pre-results.

Abstract
BACKGROUND Early onset eczema is associated with food allergy, and allergic reactions to foods can cause acute exacerbations of eczema. Parents often pursue dietary restrictions as a way of managing eczema and seek allergy testing for their children to guide dietary management. However, it is unclear whether test-guided dietary management improves eczema symptoms, and whether the practice causes harm through reduced use of conventional eczema treatment or unnecessary dietary restrictions. The aim of the Trial of Eczema allergy Screening Tests Study is to determine the feasibility of conducting a trial comparing food allergy testing and dietary advice versus usual care, for the management of eczema in children. METHODS AND ANALYSIS Design: A single centre, two-group, individually randomised, feasibility randomised controlled trial (RCT) with economic scoping and a nested qualitative study. SETTING General Practioner (GP) surgeries in the west of England. PARTICIPANTS children aged over 3 months and less than 5 years with mild to severe eczema. INTERVENTIONS allergy testing (structured allergy history and skin prick tests) or usual care. Sample size and outcome measures: we aim to recruit 80 participants and follow them up using 4-weekly questionnaires for 24 weeks. Nested qualitative study: We will conduct ~20 interviews with parents of participating children, 5-8 interviews with parents who decline or withdraw from the trial and ~10 interviews with participating GPs. Economic scoping: We will gather data on key costs and outcomes to assess the feasibility of carrying out a cost-effectiveness analysis in a future definitive trial. ETHICS AND DISSEMINATION The study has been reviewed by the Health Research Authority and given a favourable opinion by the NHS REC (West Midlands - South Birmingham Research Ethics Committee, Reference Number 18/WM/0124). Findings will be submitted for presentation at conferences and written up for publication in peer-reviewed journals, which may include mixed-method triangulation and integration of the quantitative and qualitative findings.

BACKGROUND Childhood eczema is very common. Treatment often includes emollient bath additives, despite there being little evidence of their effectiveness. OBJECTIVES To determine the clinical effectiveness and cost-effectiveness of emollient bath additives in the management of childhood eczema. DESIGN Pragmatic, randomised, open-label, multicentre superiority trial with two parallel groups. SETTING Ninety-six general practices in Wales, the west of England and southern England. Invitation by personal letter or opportunistically. PARTICIPANTS Children aged between 12 months and 12 years fulfilling the UK Diagnostic Criteria for Atopic Eczema. Children with inactive or very mild eczema (a score of ≤ 5 on the Nottingham Eczema Severity Scale) were excluded, as were children who bathed less than once per week or whose parents/carers were not prepared to accept randomisation. INTERVENTIONS The intervention group were prescribed bath additives by their usual clinical team and were asked to use them regularly for 12 months. The control group were asked to use no bath additives for 12 months. Both groups continued standard eczema management, including regular leave-on emollients and topical corticosteroids (TCSs) when required. MAIN OUTCOME MEASURES The primary outcome was eczema control measured by Patient Oriented Eczema Measure [POEM, 0 (clear) to 28 (severe)] weekly for 16 weeks. The secondary outcomes were eczema severity over 1 year (4-weekly POEM), number of eczema exacerbations, disease-specific quality of life (QoL) (Dermatitis Family Impact Questionnaire), generic QoL (Child Health Utility-9 Dimensions) and type and quantity of topical steroid/calcineurin inhibitors prescribed. Children were randomised (1 : 1) using online software to either bath additives plus standard eczema care or standard eczema care alone, stratified by recruiting centre, and there was open-label blinding. RESULTS From December 2014 to May 2016, 482 children were randomised: 51% were female, 84% were white and the mean age was 5 years (n = 264 in the intervention group, n = 218 in the control group). Reported adherence to randomised treatment allocation was > 92% in both groups, with 76.7% of participants completing at least 12 (80%) of the first 16 weekly questionnaires for the primary outcome. Baseline POEM score was 9.5 [standard deviation (SD) 5.7] in the bath additives group and 10.1 (SD 5.8) in the no bath additives group. Average POEM score over the first 16 weeks was 7.5 (SD 6.0) in the bath additives group and 8.4 (SD 6.0) in the no bath additives group, with no statistically significant difference between the groups. After controlling for baseline severity and confounders (ethnicity, TCS use, soap substitute use) and allowing for clustering of participants within centres and responses within participants over time, POEM scores in the no bath additive group were 0.41 points higher than in the bath additive group (95% confidence interval -0.27 to 1.10), which is well below the published minimal clinically important difference of 3 points. There was no difference between groups in secondary outcomes or in adverse effects such as redness, stinging or slipping. LIMITATIONS Simple randomisation resulted in an imbalance in baseline group size, although baseline characteristics were well balanced between groups. CONCLUSION This trial found no evidence of clinical benefit of including emollient bath additives in the standard management of childhood eczema. FUTURE WORK Further research is required on optimal regimens of leave-on emollients and the use of emollients as soap substitutes. TRIAL REGISTRATION Current Controlled Trials ISRCTN84102309.

A Randomized Controlled Trial of an Eczema Care Plan. Acad Pediatr 2018; 18:789-796. [PMID: 29505898 DOI: 10.1016/j.acap.2018.02.015] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2017] [Revised: 02/19/2018] [Accepted: 02/24/2018] [Indexed: 01/17/2023]
Abstract
OBJECTIVE To test whether an eczema care plan (ECP) would improve provider documentation and management, decrease eczema severity, and increase patient quality of life (QOL) in the pediatric primary care setting. METHODS We conducted a randomized controlled trial from June 2015 to September 2016 at a large hospital-based pediatric primary care clinic. Participants included children from 1 month to 16 years of age with a diagnosis of eczema. The intervention group received the ECP and the control group received usual care. Both groups completed a validated eczema severity scale (Patient-Oriented Eczema Measure [POEM]) and a QOL scale (Infant's Dermatitis Quality of Life Index [IDQOL]) or Children's Dermatology Life Quality Index [CDLQI]) before the visit and again ~1 month later. RESULTS A total of 211 caregivers completed both the pre- and postintervention surveys (100 control group and 111 intervention group [94% completion]). Intervention group providers were more likely to recommend a comprehensive "step-up" plan (88%) vs 28%; P < .001, bleach baths (45%) vs 9%; P < .001, and wet wraps (50%) vs 7%; P < .001. They were also more likely to document providing a written plan to families (80%) vs 2%; P < .001. In the intervention and control groups, eczema severity and QOL improved between the pre- and postintervention periods. However, there was not a significant difference between the groups on either measure: POEM difference -0.8, 95% confidence interval (CI) -3.2 to 1.7; IDQOL difference -0.1, 95% CI -1.8 to 1.6; CDLQI difference 0.8, 95% CI -0.9 to 2.6. CONCLUSIONS Intervention group providers documented more comprehensive eczema care than control group providers. Although patients improved on all measures in the postintervention period, the ECP did not augment that improvement.

Abstract
BACKGROUND Eczema affects around 20% of children, but multiple different outcome measures have hampered research into the effectiveness of different treatments. OBJECTIVES To compare the change in scores and correlations within and between five measures of eczema severity: Patient-Orientated Eczema Measure (POEM), Eczema Area and Severity Index (EASI), Six Area, Six Sign Atopic Dermatitis (SASSAD), Three Item Severity (TIS) and skin hydration (corneometry). METHODS Data from a feasibility trial that randomized young children with eczema to one of four emollients were used. Participants were followed for 3 months (84 days). Descriptive statistics (by emollient over time) and Spearman's correlation coefficients comparing scores at each time point and absolute change (between adjacent time points) for each outcome measure were calculated. RESULTS In total, 197 children, mean ± SD age 21·7 ± 12·8 months, were randomized. POEM and TIS appeared to capture a range of eczema severity at baseline, but only POEM had close approximation to normal distribution. Mean POEM, EASI, SASSAD and TIS scores improved month by month, with POEM showing the greatest sensitivity (effect size 0·42). Correlations within POEM, EASI, SASSAD and TIS were moderate to good, decreasing over time. Correlations between measures were strongest for EASI, SASSAD and TIS. By contrast, corneometry scores were more variable, correlated less well over time and were poorly correlated with the other measures. CONCLUSIONS Except for corneometry, all measures appear to change in relation to emollient use over time and correlate well with themselves. POEM demonstrated the greatest range of scores at baseline and change in eczema severity over the first 28 days.

Abstract
OBJECTIVES To determine the clinical effectiveness and cost effectiveness of including emollient bath additives in the management of eczema in children. DESIGN Pragmatic randomised open label superiority trial with two parallel groups. SETTING 96 general practices in Wales and western and southern England. PARTICIPANTS 483 children aged 1 to 11 years, fulfilling UK diagnostic criteria for atopic dermatitis. Children with very mild eczema and children who bathed less than once weekly were excluded. INTERVENTIONS Participants in the intervention group were prescribed emollient bath additives by their usual clinical team to be used regularly for 12 months. The control group were asked to use no bath additives for 12 months. Both groups continued with standard eczema management, including leave-on emollients, and caregivers were given standardised advice on how to wash participants. MAIN OUTCOME MEASURES The primary outcome was eczema control measured by the patient oriented eczema measure (POEM, scores 0-7 mild, 8-16 moderate, 17-28 severe) weekly for 16 weeks. Secondary outcomes were eczema severity over one year (monthly POEM score from baseline to 52 weeks), number of eczema exacerbations resulting in primary healthcare consultation, disease specific quality of life (dermatitis family impact), generic quality of life (child health utility-9D), utilisation of resources, and type and quantity of topical corticosteroid or topical calcineurin inhibitors prescribed. RESULTS 483 children were randomised and one child was withdrawn, leaving 482 children in the trial: 51% were girls (244/482), 84% were of white ethnicity (447/470), and the mean age was 5 years. 96% (461/482) of participants completed at least one post-baseline POEM, so were included in the analysis, and 77% (370/482) completed questionnaires for more than 80% of the time points for the primary outcome (12/16 weekly questionnaires to 16 weeks). The mean baseline POEM score was 9.5 (SD 5.7) in the bath additives group and 10.1 (SD 5.8) in the no bath additives group. The mean POEM score over the 16 week period was 7.5 (SD. 6.0) in the bath additives group and 8.4 (SD 6.0) in the no bath additives group. No statistically significant difference was found in weekly POEM scores between groups over 16 weeks. After controlling for baseline severity and confounders (ethnicity, topical corticosteroid use, soap substitute use) and allowing for clustering of participants within centres and responses within participants over time, POEM scores in the no bath additives group were 0.41 points higher than in the bath additives group (95% confidence interval -0.27 to 1.10), below the published minimal clinically important difference for POEM of 3 points. The groups did not differ in secondary outcomes, economic outcomes, or adverse effects. CONCLUSIONS This trial found no evidence of clinical benefit from including emollient bath additives in the standard management of eczema in children. Further research is needed into optimal regimens for leave-on emollient and soap substitutes. TRIAL REGISTRATION Current Controlled Trials ISRCTN84102309.

Br J Dermatol 2018; 178:1135-1142. [PMID: 29355894 PMCID: PMC6001667 DOI: 10.1111/bjd.16367] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/11/2018] [Indexed: 11/28/2022]
Abstract
Background The Patient‐Oriented Eczema Measure (POEM), scored 0–28, is the core outcome instrument recommended for measuring patient‐reported atopic eczema symptoms in clinical trials. To date, two published studies have broadly concurred that the minimally important change (MIC) of the POEM is three points. Further assessment of the MIC of POEM in different populations, and using a variety of methods, will improve interpretability of the POEM in research and clinical practice. Objectives To calculate the smallest detectable change in the POEM and estimate the MIC of the POEM using a variety of methods in a trial dataset of children with moderate‐to‐severe atopic eczema. Methods This study used distribution‐based and anchor‐based methods to calculate the MIC of the POEM in children with moderate‐to‐severe eczema. Results Data were collected from 300 children. The smallest detectable change was 2·13. The MIC estimates were 1·07 (using 0·2 SD of baseline POEM scores) and 2·68 (using 0·5 SD of baseline POEM scores) based on distribution‐based methods; were 3·09–6·13 based on patient‐/parent‐reported anchor‐based methods; and were 3·23–5·38 based on investigator‐reported anchor‐based methods. Conclusions We recommend the following thresholds be used to interpret changes in POEM scores: ≤ 2, unlikely to be a change beyond measurement error; 2·1–2·9, a small change detected that is likely to be beyond measurement error but may not be clinically important; 3–3·9, probably a clinically important change; ≥ 4, very likely to be a clinically important change. What's already known about this topic? The Patient‐Oriented Eczema Measure (POEM) is recommended as the core outcome instrument for measuring patient‐reported symptoms in eczema clinical trials. Two previous studies have examined the minimally important change (MIC) of the POEM; one in children with mild eczema and another in adults with very severe eczema. These previous studies both concluded that the MIC in POEM is around three points.
What does this study add? This study explored the impact of different methodologies for calculating the MIC of the POEM in children with moderate‐to‐severe eczema. A change in POEM of less than two points is likely to be below the smallest detectable change (i.e. below measurement error) for the scale. The MIC varied considerably depending on the method used, but a change in POEM score below three points is unlikely to be a clinically important change.
What are the clinical implications of this work? This study aids sample size calculations for clinical trials and helps researchers, clinicians and patients to interpret changes in POEM scores in clinical trials and routine monitoring of eczema in clinical practice.

Abstract
Eczema is a common long‐term condition, but inadequate support and information can lead to poor adherence and treatment failure. We have reviewed the international literature of interventions designed to promote self‐management in adults and children with eczema. MEDLINE, MEDLINE in process, Embase, CINAHL and the Global Resource for EczemA Trials database were searched from their inception to August 2016, for randomized controlled trials. Two authors independently applied eligibility criteria, assessed risk of bias for all included studies and extracted data. Twenty studies (3028 participants) conducted in 11 different countries were included. The majority (n = 18) were based in secondary care and most (n = 16) targeted children with eczema. Reporting of studies, including descriptions of the interventions and the outcomes themselves, was generally poor. Thirteen studies were face‐to‐face educational interventions, five were delivered online and two were studies of written action plans. Follow‐up in most studies (n = 12) was short term (up to 12 weeks). Only six trials specified a single primary outcome. There was limited evidence of effectiveness. Only three studies collected and reported outcomes related to cost and just one study undertook any formal cost‐effectiveness analysis. In summary, we have identified a general absence of well‐conducted and well‐reported randomized controlled trials with a strong theoretical basis. Therefore, there is still uncertainty about how best to support self‐management of eczema in a clinically effective and cost‐effective way. Recommendations on design and conduct of future trials are presented. What's already known about this topic? Eczema requires a high degree of self‐management by patients. Adherence to eczema treatments, and hence control of symptoms, can be poor. There is uncertainty about how best to support self‐management in a clinically effective and cost‐effective way.
What does this study add?A wide range of interventions designed to promote self‐management have been evaluated in 20 studies across 11 different countries. Reporting of the design and conduct of these studies is generally poor, and explicit theory describing how interventions are expected to improve care is uncommon. What works best for people with eczema and whether it is cost‐effective is unknown. Recommendations for future trials are made.

Oral and Topical Antibiotics for Clinically Infected Eczema in Children: A Pragmatic Randomized Controlled Trial in Ambulatory Care. Ann Fam Med 2017; 15:124-130. [PMID: 28289111 PMCID: PMC5348229 DOI: 10.1370/afm.2038] [Citation(s) in RCA: 30] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2016] [Revised: 10/26/2016] [Accepted: 11/20/2016] [Indexed: 12/25/2022] Open
Abstract
PURPOSE Eczema may flare because of bacterial infection, but evidence supporting antibiotic treatment is of low quality. We aimed to determine the effect of oral and topical antibiotics in addition to topical emollient and corticosteroids in children with clinically infected eczema. METHODS We employed a 3-arm, blinded, randomized controlled trial in UK ambulatory care. Children with clinical, non-severely infected eczema were randomized to receive oral and topical placebos (control), oral antibiotic (flucloxacillin) and topical placebo, or topical antibiotic (fusidic acid) and oral placebo, for 1 week. We compared Patient Oriented Eczema Measure (POEM) scores at 2 weeks using analysis of covariance (ANCOVA). RESULTS We randomized 113 children (40 to control, 36 to oral antibiotic, and 37 to topical antibiotic). Mean (SD) baseline Patient Oriented Eczema Measure scores were 13.4 (5.1) for the control group, 14.6 (5.3) for the oral antibiotic group, and 16.9 (5.5) for the topical antibiotic group. At baseline, 104 children (93%) had 1 or more of the following findings: weeping, crusting, pustules, or painful skin. Mean (SD) POEM scores at 2 weeks were 6.2 (6.0) for control, 8.3 (7.3) for the oral antibiotic group, and 9.3 (6.2) for the topical antibiotic group. Controlling for baseline POEM score, neither oral nor topical antibiotics produced a significant difference in mean (95% CI) POEM scores (1.5 [-1.4 to 4.4] and 1.5 [-1.6 to 4.5] respectively). There were no significant differences in adverse effects and no serious adverse events. CONCLUSIONS We found rapid resolution in response to topical steroid and emollient treatment and ruled out a clinically meaningful benefit from the addition of either oral or topical antibiotics. Children seen in ambulatory care with mild clinically infected eczema do not need treatment with antibiotics.

Abstract
BACKGROUND Eczema is a chronic skin disease characterised by dry skin, intense itching, inflammatory skin lesions, and a considerable impact on quality of life. Moisturisation is an integral part of treatment, but it is unclear if moisturisers are effective. OBJECTIVES To assess the effects of moisturisers for eczema. SEARCH METHODS We searched the following databases to December 2015: Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase, LILACS, the GREAT database. We searched five trials registers and checked references of included and excluded studies for further relevant trials. SELECTION CRITERIA Randomised controlled trials in people with eczema. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodological procedures. MAIN RESULTS We included 77 studies (6603 participants, mean age: 18.6 years, mean duration: 6.7 weeks). We assessed 36 studies as at a high risk of bias, 34 at unclear risk, and seven at low risk. Twenty-four studies assessed our primary outcome 'participant-assessed disease severity', 13 assessed 'satisfaction', and 41 assessed 'adverse events'. Secondary outcomes included investigator-assessed disease severity (addressed in 65 studies), skin barrier function (29), flare prevention (16), quality of life (10), and corticosteroid use (eight). Adverse events reporting was limited (smarting, stinging, pruritus, erythema, folliculitis).Six studies evaluated moisturiser versus no moisturiser. 'Participant-assessed disease severity' and 'satisfaction' were not assessed. Moisturiser use yielded lower SCORAD than no moisturiser (three studies, 276 participants, mean difference (MD) -2.42, 95% confidence interval (CI) -4.55 to -0.28), but the minimal important difference (MID) (8.7) was unmet. There were fewer flares with moisturisers (two studies, 87 participants, RR 0.40, 95% CI 0.23 to 0.70), time to flare was prolonged (median: 180 versus 30 days), and less topical corticosteroids were needed (two studies, 222 participants, MD -9.30 g, 95% CI -15.3 to -3.27). There was no statistically significant difference in adverse events (one study, 173 participants, risk ratio (RR) 15.34, 95% CI 0.90 to 261.64). Evidence for these outcomes was low quality.With Atopiclair (three studies), 174/232 participants experienced improvement in participant-assessed disease severity versus 27/158 allocated to vehicle (RR 4.51, 95% CI 2.19 to 9.29). Atopiclair decreased itching (four studies, 396 participants, MD -2.65, 95% CI -4.21 to -1.09) and achieved more frequent satisfaction (two studies, 248 participants, RR 2.14, 95% CI 1.58 to 2.89), fewer flares (three studies, 397 participants, RR 0.18, 95% CI 0.11 to 0.31), and lower EASI (four studies, 426 participants, MD -4.0, 95% CI -5.42 to -2.57), but MID (6.6) was unmet. The number of participants reporting adverse events was not statistically different (four studies, 430 participants, RR 1.03, 95% CI 0.79 to 1.33). Evidence for these outcomes was moderate quality.Participants reported skin improvement more frequently with urea-containing cream than placebo (one study, 129 participants, RR 1.28, 95% CI 1.06 to 1.53; low-quality evidence), with equal satisfaction between the two groups (one study, 38 participants, low-quality evidence). Urea-containing cream improved dryness (investigator-assessed) more frequently (one study, 128 participants, RR 1.40, 95% CI 1.14 to 1.71; moderate-quality evidence) with fewer flares (one study, 44 participants, RR 0.47, 95% CI 0.24 to 0.92; low-quality evidence), but more participants in this group reported adverse events (one study, 129 participants, RR 1.65, 95% CI 1.16 to 2.34; moderate-quality evidence).Three studies assessed glycerol-containing moisturiser versus vehicle or placebo. More participants in the glycerol group noticed skin improvement (one study, 134 participants, RR 1.22, 95% CI 1.01 to 1.48; moderate-quality evidence), and this group saw improved investigator-assessed SCORAD (one study, 249 participants, MD -2.20, 95% CI -3.44 to -0.96; high-quality evidence), but MID was unmet. Participant satisfaction was not addressed. The number of participants reporting adverse events was not statistically significant (two studies, 385 participants, RR 0.90, 95% CI 0.68 to 1.19; moderate-quality evidence).Four studies investigated oat-containing moisturisers versus no treatment or vehicle. No significant differences between groups were reported for participant-assessed disease severity (one study, 50 participants, RR 1.11, 95% CI 0.84 to 1.46; low-quality evidence), satisfaction (one study, 50 participants, RR 1.06, 95% CI 0.74 to 1.52; very low-quality evidence), and investigator-assessed disease severity (three studies, 272 participants, standardised mean difference (SMD) -0.23, 95% CI -0.66 to 0.21; low-quality evidence). In the oat group, there were fewer flares (one study, 43 participants, RR 0.31, 95% CI 0.12 to 0.7; low-quality evidence) and less topical corticosteroids needed (two studies, 222 participants, MD -9.30g, 95% CI 15.3 to -3.27; low-quality evidence), but more adverse events were reported (one study, 173 participants; Peto odds ratio (OR) 7.26, 95% CI 1.76 to 29.92; low-quality evidence).All moisturisers above were compared to placebo, vehicle, or no moisturiser. Participants considered moisturisers more effective in reducing eczema (five studies, 572 participants, RR 2.46, 95% CI 1.16 to 5.23; low-quality evidence) and itch (seven studies, 749 participants, SMD -1.10, 95% CI -1.83 to -0.38) than control. Participants in both treatment arms reported comparable satisfaction (three studies, 296 participants, RR 1.35, 95% CI 0.77 to 2.26; low-quality evidence). Moisturisers led to lower investigator-assessed disease severity (12 studies, 1281 participants, SMD -1.04, 95% CI -1.57 to -0.51; high-quality evidence) and fewer flares (six studies, 607 participants, RR 0.33, 95% CI 0.17 to 0.62; moderate-quality evidence), but there was no difference in adverse events (10 studies, 1275 participants, RR 1.03, 95% CI 0.82 to 1.30; moderate-quality evidence).Topical active treatment combined with moisturiser was more effective than active treatment alone in reducing investigator-assessed disease severity (three studies, 192 participants, SMD -0.87, 95% CI -1.17 to -0.57; moderate-quality evidence) and flares (one study, 105 participants, RR 0.43, 95% CI 0.20 to 0.93), and was preferred by participants (both low-quality evidence). There was no statistically significant difference in number of adverse events (one study, 125 participants, RR 0.39, 95% CI 0.13 to 1.19; very low-quality evidence). Participant-assessed disease severity was not addressed. AUTHORS' CONCLUSIONS Most moisturisers showed some beneficial effects, producing better results when used with active treatment, prolonging time to flare, and reducing the number of flares and amount of topical corticosteroids needed to achieve similar reductions in eczema severity. We did not find reliable evidence that one moisturiser is better than another.

Abstract
Background The Patient‐Oriented Eczema Measure (POEM) has been recommended as the core patient‐reported outcome measure for trials of eczema treatments. Using data from the Choice of Moisturiser for Eczema Treatment randomized feasibility study, we assess the responsiveness to change and determine the minimal clinically important difference (MCID) of the POEM in young children with eczema. Methods Responsiveness to change by repeated administrations of the POEM was investigated in relation to change recalled using the Parent Global Assessment (PGA) measure. Five methods of determining the MCID of the POEM were employed; three anchor‐based methods using PGA as the anchor: the within‐patient score change, between‐patient score change and sensitivity and specificity method, and two distribution‐based methods: effect size estimate and the one half standard deviation of the baseline distribution of POEM scores. Results Successive POEM scores were found to be responsive to change in eczema severity. The MCID of the POEM change score, in relation to a slight improvement in eczema severity as recalled by parents on the PGA, estimated by the within‐patient score change (4.27), the between‐patient score change (2.89) and the sensitivity and specificity method (3.00) was similar to the one half standard deviation of the POEM baseline scores (2.94) and the effect size estimate (2.50). Conclusions The Patient‐Oriented Eczema Measure as applied to young children is responsive to change, and the MCID is around 3. This study will encourage the use of POEM and aid in determining sample size for future randomized controlled trials of treatments for eczema in young children.
