Background: The heterogeneity of development and progression of eczema suggests multiple underlying subclasses for which aetiology and prognosis may vary. A better understanding may provide a comprehensive overview of eczema development and progression in childhood. Thus, we aimed to determine longitudinal eczema subclasses based on assessments and identify their associations with risk factors and allergic outcomes. Methods: A total of 619 participants with a family history of allergic disease were assessed at 24 time‐points from birth to 12 years. At each time, eczema was defined as the report of current rash treated with topical steroid‐based preparations. Longitudinal latent class analysis was used to determine eczema subclasses. Subsequent analyses using regression models assessed the associations between eczema subclasses and potential risk factors and allergic outcomes at 18‐ and 25‐year follow‐ups (eczema, allergic rhinitis, asthma and allergic sensitization). Results: We identified five eczema subclasses 'early‐onset persistent', 'early‐onset resolving', 'mid‐onset persistent', 'mid‐onset resolving' and 'minimal eczema'. Filaggrin null mutations were associated with the early‐onset persistent (OR = 2.58 [1.09–6.08]) and mid‐onset persistent class (OR = 2.58 [1.32–5.06]). Compared with 'minimal eczema', participants from early‐onset persistent class had higher odds of eczema (OR = 11.8 [5.20–26.6]) and allergic rhinitis (OR = 3.13 [1.43–6.85]) at 18 and at 25 years eczema (OR = 9.37 [3.17–27.65]), allergic rhinitis (OR = 3.26 [1.07–9.93]) and asthma (OR = 2.91 [1.14–7.43]). Likewise, mid‐onset persistent class had higher odds of eczema (OR = 2.59 [1.31–5.14]), allergic rhinitis (OR = 1.70 [1.00–2.89]) and asthma (OR = 2.00 [1.10–3.63]) at 18 and at 25 years eczema (OR = 6.75 [3.11–14–65]), allergic rhinitis (OR = 2.74 [1.28–5.88]) and asthma (OR = 2.50 [1.25–5.00]). Allergic and food sensitization in early life was more common in those in the persistent eczema subclasses. Conclusion: We identified five distinct eczema subclasses. These classes were differentially associated with risk factors, suggesting differences in aetiology, and also with the development of allergic outcomes, highlighting their potential to identify high‐risk groups for close monitoring and intervention.

Context It has been hypothesized that a mother's diet during pregnancy may modulate her offspring's immune system development and lead to development of allergic diseases among offspring. However, the evidence for this is unclear and inconclusive. Objective This systematic review was undertaken to examine the weight of evidence for causality from cohort studies on the association between maternal free sugar intake during pregnancy and development of allergies in offspring. Data Sources Using a systematic search strategy, PubMed, SCOPUS, and Web of Science databases were searched from inception to May 2020. Data Extraction For the reporting of this systematic review, the PRISMA guideline was followed. Studies examining maternal sugar consumption during pregnancy (using self-reported data) and the development of allergic diseases among offspring (infancy to 5 years) were included. Data Analysis The Newcastle–Ottawa Scale quality assessment tool was used to assess the study quality. Meta-analysis was conducted using a random-effects model to synthesize the findings. Of 159 publications identified from the search, 5 articles with 4 unique cohort studies were included in this systematic review. The limited meta-analysis showed that a mother's increased free sugar intake during pregnancy was associated with an increased risk of developing asthma in offspring (odds ratio 1.07 [95% CI, 1.00 to 1.14; I2 = 0%]). High free sugar intake by the mother during pregnancy was also associated with increased odds of offspring (to age 7.7 years) developing other common allergies, including allergic rhinitis, atopy and eczema, wheeze, and food allergies. Conclusion From the limited evidence, this review suggests that high free sugar consumption during pregnancy may be associated with the development of allergies in offspring. Clinical guidelines and public health policy recommendations for maternal diet in pregnancy should include advice about reducing free sugar intake due to a possible association with allergies in offspring. However, recommendations should be made with caution considering other maternal and fetal risk factors. [ABSTRACT FROM AUTHOR]
