Moderate to severe atopic dermatitis in children: focus on systemic Th2 cytokine receptor antagonists and Janus kinase inhibitors
Jeong Hee Kim, Mona Salem Samra
Clin Exp Pediatr. 2024;67(2):64-79.   Published online June 14, 2023
· Atopic dermatitis (AD) is characterized by a strong T helper (Th)2 response, although the extents of Th22, Th17/ interleukin (IL)-23, and Th1 responses vary among disease subtypes.
· Children with moderate to severe AD may require early systemic therapy to reduce the systemic inflammation caused by increased Th2 cytokine levels.
· Dupilumab, which blocks IL-4/IL-13 receptor, has equivalent efficacy for extrinsic and intrinsic AD and a favorable safety profile in infants and children aged 6 months and older.
Skin and oral intervention for food allergy prevention based on the dual allergen exposure hypothesis
Kiwako Yamamoto-Hanada, Yukihiro Ohya
Early-onset atopic dermatitis increases the risk of food allergies, suggesting that transcutaneous sensitization may occur through inflamed skin. Regarding food allergy causation, the dual allergen exposure hypothesis proposes that oral-route allergen exposure leads to immune tolerance, whereas allergen exposure via the inflamed skin causes food allergy. This hypothesis implies that it is important to induce oral immune tolerance and prevent...

Influence of age at complementary food introduction on the development of asthma and atopic dermatitis in Korean children aged 1–3 years
Jihyun Lee, Meeyong Shin, Bora Lee
Clin Exp Pediatr. 2021;64(8):408-414.   Published online November 1, 2020
Question: Is age at the time of complementary food introduction associated with asthma and atopic dermatitis (AD) in early childhood?
Finding: We found no significant association between age at the time of complementary food introduction and the incidence of AD and asthma in Koreans aged 1–3 years.
Meaning: Our findings suggest that the influence of individual allergenic foods on the development of AD and asthma should be clarified.

Clin Exp Pediatr. 2018;61(6):200-204.   Published online June 25, 2018

Atopic dermatitis (AD) is a chronic inflammatory skin disease in children. Patients with AD experience a high rate of colonization of the skin surface by Staphylococcus aureus. Because of a skin barrier defect, there is a potential risk of staphylococcal invasive infection in patients with AD. Here, we present 2 cases of breast abscess caused by S. aureus in 2...

Clin Exp Pediatr. 2016;59(8):319-327.   Published online August 24, 2016

Allergic diseases such as asthma, allergic rhinitis, atopic dermatitis, and food allergy, are most common chronic, noncommunicable diseases in childhood. In the past few decades, the prevalence has increased abruptly worldwide. There are 2 possible explanations for the rising prevalence of allergic diseases worldwide, that an increased disease-awareness of physician, patient, or caregivers, and an abrupt exposure to unknown hazards....

Clin Exp Pediatr. 2016;59(5):218-225.   Published online May 31, 2016
Purpose

The recent increase in the prevalence of allergic diseases is hypothetically attributed to immune dysregulation in turn caused by a reduction in exposure to sunlight. We explored relationships between birth season, sunlight exposure, exercise duration, and an allergic disease.

Methods

We performed a questionnaire-based survey on allergic diseases among elementary school students. Birth time was categorized according to the season (summer and...

Relationship between serum 25-hydroxyvitamin D and interleukin-31 levels, and the severity of atopic dermatitis in children

Atopic dermatitis (AD) is a chronic inflammatory relapsing skin disorder. Vitamin D plays a pivotal role in the development of AD, and interleukin (IL) 31 is known to be related to pruritus in AD. The aim of our study was to determine whether 25-hydroxyvitamin D (25(OH)D) levels are related to IL-31 levels or to the severity of AD.
