“…Filaggrin deficiency contributes to inherent barrier defects in atopic skin that, in combination with the effects of inflammatory cytokines and environmental factors, results in the development of AD . Studies in Europeans and Asians have consistently demonstrated that loss‐of‐function mutations in the FLG gene, present in up to 50% of European and 27% of Asian AD cases, are a major predisposing factor for the development of AD . Patients with FLG mutations exhibit earlier onset of AD, more severe disease, a higher rate of eczema herpeticum, and a greater incidence of other atopic diseases as compared to those with wild‐type FLG .…”

Atopic dermatitis (AD) is a chronic inflammatory skin condition that affects diverse ethnic groups with varying prevalence. Despite a predominance of studies in individuals of European ancestry, AD has been found to occur more frequently in Asian and Black individuals than Whites. Therefore, an understanding of the unique clinical features of AD in diverse ethnic groups, as well as the differences in genetic polymorphisms that influence susceptibility to AD and response to current therapies, is paramount for management of an increasingly diverse patient population. In this article, we review key nuances in the epidemiology, pathophysiology, clinical presentation and treatment of AD in non-White ethnic groups, which are largely underappreciated in the literature. We highlight the need for studies evaluating the tissue molecular and cellular phenotypes of AD in non-White patients, as well as greater inclusion of minority groups in clinical trials, to develop targeted treatments for a multi-ethnic population.

“…Our result was consistent with other studies in Germany [5] and in Danemark [7] which found that manifestation of atopy is not related to patient's month of birth. However, a population-based study in Taiwan find that patients born in December, October and November (dry season) have high risk of developing AD, this study hypothesize that the skin condition is affected by the climate in early infancy [4]. A japanese study reported also that children born in autumn (october, november and december) had higher risk to develop AD compared to those born in spring (april, may and june) [6].…”

BACKGROUND: Several studies have been done to evaluate the relationship between month of birth and atopic diseases but the results are contradictory. So, we aim to evaluate the correlation between the month of birth and the prevalence of AD in Malagasy children less than 3 years.METHODS: A case-control study was conducted based on patients’ data of the department of Dermatology in the University Hospital Joseph Raseta Befelatanana (UH/JRB) Antananarivo. It included 354 children less than 3 years seen in this department between January 2010 and December 2018. For each AD patient, two age and sex-matched controls without a history of AD were selected from the same period.RESULTS: This study included 118 AD cases and 236 non-AD controls. Our case-control study found that there are no statistically significant correlation between birth month and risk of AD in Malagasy children < 3 years. However, the fewest children with AD were born in February (17.86%, OR: 0.40, CI 95%: 0.11-1.14), and the most were born in August (45.16%, OR: 1,73; CI 95%: 0,75-3,88). Asthma, allergic rhinitis and allergic conjunctivitis were significantly correlated with AD in our patients.CONCLUSION: Our case-control study found that there are no statistically significant correlation between birth month and risk of AD in children < 3 years. However, the high frequency of AD in children born in August (dry season) compared to non-AD controls was not negligible (p-value =0,05 and X 2 3,27).

“…Развитие АД обусловлено генетически обусловленными иммунными механизмами, что показано в многочисленных научных исследованиях. Если один из родителей страдает любым аллергическим заболеванием, то риск развития атопии у ребенка возрастает в 2 раза, если оба -то в 5 раз [19]. К основным триггерным факторам развития АД относятся: патологическое течение беременности и родов, плановое кесарево сечение, использование антибиотиков в перинатальном периоде, отказ от грудного вскармливания, раннее введение цельного молочного белка.…”

Food allergies in children: why has there been an increase in the prevalence rates?

The prevalence of allergic diseases and asthma are increasing worldwide. Scientists say up to 30–40% of the adult population have various forms of allergy (gastrointestinal, skin, respiratory, isolated or combined) in recent years. There is no tendency for the number of children with this pathology to reduce despite a deeper understanding of the pathogenesis of atopic diseases and the achievements of pharmacology. Experts in various health areas (paediatricians, allergists, dermatologists, immunologists, gastroenterologists) actively discuss the role of the intestinal microbiota in the mechanisms of the development of food allergies. The article discusses the pathogenesis of food allergies and atopic dermatitis in children, discusses the possibility of using probiotics in complex therapy, taking into account the results of global clinical studies.

Birth month and risk of atopic dermatitis: a nationwide population-based study

Abstract: Being born in December, October, or November may be associated with an increased risk of AD. Future investigations are needed to evaluate the possible mechanism behind the association between birth month and AD.
