Emollients for preventing atopic eczema: Cost-effectiveness analysis of the BEEP trial

[Consensus for the treatment of atopic dermatitis in primary care: resolving myths and legends based on evidence]

Atopic dermatitis (AD) is a disease that significantly impacts the quality of life of patients. Although there are multiple evidence-based guidelines, they are usually aimed at providing recommendations to AD specialists rather than primary care physicians (PCPs). The aim of this study was to construct a consensus document for PCPs, with the aim of presenting evidence-based recommendations that allow general practitioners, family physicians, pediatricians, internists and emergency physicians to provide appropriate care to AD patients, facilitating their diagnosis, management, and avoiding delays that can deteriorate patients' f quality of life. As a central source of information, we used the recommendations of different international AD guidelines. Delegates from distinct medical societies identify barriers to care and possible solutions for the application of recommendations in primary care. Subsequently, a second evaluation for physicians from different Latin American countries was carried out. The main doubts and barriers that PCPs face in applying the recommendations proposed by the guidelines were identified across different areas, diagnostic criteria, non-pharmacological therapies, pharmacological therapies, management in special conditions and guidelines for referral to a specialist. Consensus solutions were proposed for each identified issue. In conclusion, this consensus contains recommendations regarding the management and treatment of AD in children and adults, which clarify doubts and provide tools to primary care physicians to offer effective treatment for patients and their families.

Practicality, Validity, and Responsiveness of Using the Proxy Version of the Child Health Utility-9 Dimensions With Children Aged 2 to 5 Years

OBJECTIVES

This study aimed to assess the practicality, validity, and responsiveness of the proxy Child Health Utility-9 Dimensions (CHU9D) in children aged 2 to 5 years.

METHODS

We used data from the Barrier Enhancement for Eczema Prevention trial, a UK randomized controlled trial testing whether daily emollients in infancy could prevent eczema in high-risk infants. The main parent/carer completed the proxy CHU9D using developers' additional guidance for completion in those younger than 5 years and the Patient-Oriented Eczema Measure (POEM) at ages 2, 3, 4, and 5 years. Practicality was assessed by completion rates. Construct validity assessed whether CHU9D could discriminate between those with/without eczema and between eczema severity levels on POEM. Responsiveness was determined by ability to discriminate between 3 groups: (1) those whose POEM score deteriorated ≥3 points, (2) those whose change was not clinically important (-2.9 to 2.9 points), and (3) those whose POEM score improved ≥3 points. Analysis was conducted in Stata 17.

RESULTS

Of 1394 children participating in the Barrier Enhancement for Eczema Prevention trial, study questionnaires were completed by 1212 (87%), 981 (70%), 990 (71%), and 976 (70%) at 2, 3, 4, and 5 years. Of these the CHU9D was completed by 1066 (88.0%), 685 (69.8%), 925 (93.4%), and 923 (94.6%), respectively. Mean utility at all time points was approximately 0.934 (range 0.443-1). For construct validity, very small differences in the CHU9D between known groups were observed (P < .01). A total of 801 participants had responsiveness data: 13% deteriorated, 72% had nonclinically important change, and 15% improved. Mean utility change (standardized response mean) for these groups was -0.0198 (0.21), 0.0041 (0.05), and 0.0175 (0.21) showing small change and small responsiveness.

CONCLUSIONS

Proxy CHU9D in 2- to 5-year-old children shows potential but further research is needed.

Should Emollients Be Recommended for the Prevention of Atopic Dermatitis?-New Evidence and Current State of Knowledge

INTRODUCTION

Atopic dermatitis (AD) is a chronic, pruritic skin disease with complex pathogenesis, which affects about 43 million children aged 1-4 years. One of the most known methods of alleviating symptoms of AD is emollient treatment, which varies depending on formulation and additional active ingredients. There is some evidence that emollients could be used in AD prevention in high-risk children.

MATERIALS AND METHODS

A search of the literature from Cochrane Library, PubMed and Medline was conducted between August and September 2023 with the following keywords: "atopic dermatitis", "emollients", and "prevention". Only randomised clinical trials published in the last 5 years were included into the meta-analysis.

RESULTS

Considering the inclusion criteria only 11 randomized clinical trials were taken into account, and six of them proved lack of effect of emollients in the prevention of atopic dermatitis among neonates from AD risk groups.

CONCLUSIONS

Emollient treatment has a good safety profile and most of the ingredients used in formulations are nonirritant for sensitive newborn and infant skin. There is some evidence of the positive effects of emollient treatment in prevention of AD in predisposed populations. The relatively high cost of emollient treatment (vs regular infant skin-care routine) would support the necessity for further evaluation of their effectiveness in nonpredisposed populations.
