Natural course of IgE-mediated food allergy in children
Kyunguk Jeong, Sooyoung Lee
Clin Exp Pediatr. 2023;66(12):504-511.   Published online June 14, 2023
· Dendritic, regulatory T, and regulatory B cells significantly contribute to the natural course of food allergy.
· Cow’s milk and hen’s egg allergies tend to resolve in earlier childhood but recent studies show that 50% of patients still persist into school age.
· The potential factors affecting the natural course of food allergy are age at diagnosis, symptom severity, sensitization status and its change rate, and external factors such as diet and interventions.
· There is a considerable possibility of food allergy outgrow if specific IgE levels are 2–5 kUA/L or less, but other factors such as age and recent symptoms should be considered together.
· With a clear understanding of the natural course of food allergy, pediatricians can provide appropriate assessment and interventions to our patients, and consequently can help patients overcome their food allergy and improve the social safety net.

Vitamin D serum levels in children with allergic and vasomotor rhinitis
Seung Jin Lee, Bong Hwa Kang, Bong Seok Choi
Clin Exp Pediatr. 2015;58(9):325-329.   Published online September 21, 2015
Purpose

In addition to regulating calcium and phosphorus homeostasis and bone metabolism, vitamin D is known as an immune modulator. Recently, there has been increased worldwide interest in the association between low levels of vitamin D and allergic diseases. The purpose of this study was to assess the relationship between serum vitamin D levels and allergic/vasomotor rhinitis (AR/VR) in children.

House dust mite-specific immunoglobulin E and longitudinal exhaled nitric oxide measurements in children with atopic asthma
Youn Kyung Lee, Sohyoung Yang, Joohyun Park, Heon Kim, Youn-Soo Hahn
Clin Exp Pediatr. 2015;58(3):89-95.   Published online March 20, 2015
Purpose

House dust mite (HDM) has been suggested to be the most important aeroallergen responsible for atopic asthma in Korea. We aimed to investigate that specific IgE antibodies to HDM and other common indoor aeroallergens contribute differently to total serum IgE and show different relationships with longitudinal fractional exhaled nitric oxide (FeNO) measurements in Korean atopic asthmatic patients.

Methods

A total of 193...

Analysis of cow's milk specific IgE positive patients in newborns
Gil Sang Lee, Nam Kyung Baek, Won Duck Kim
Clin Exp Pediatr. 2006;49(10):1061-1066.   Published online October 15, 2006
Purpose : The purpose of this study was to research whether measurement of cow's milk specific IgE on the newborn would be helpful in the diagnosis of cow's milk allergy. We tried to find out the relation between cow's milk specific IgE and other allergy diseases by following up cases. Methods : We reviewed clinical features of 87 episodes in infants...
A case of hyperimmunoglobulin E syndrome.
Myeong Cheol Shinn, Sung Dong Choi, Byung Gyu Suh, Jin Han Kang, Joon Sung Lee
Clin Exp Pediatr. 1991;34(2):292-298.   Published online February 28, 1991
The hyperimmunoglobulin E syndrome is a primary immunodeficiency disorder characterized by serious recurrent bacterial infections of the skin and respiratory system in early life, and markedly elevated serum IgE level. These recurrent infections are generally subcutaneous abscesses caused by Staphylococcus aureus. Also, additional characteristrics of this syndrome include coarse facial appearance, chronic pruritic dermatitis and eosinophilia. The baisic immunologic defect mechanism in hyperimmunoglobulin E syndrome is...
Serum IgE Levels in Bronchiolitis Patients.
Seong Hee Choi, Keun Lee
Clin Exp Pediatr. 1989;32(6):749-755.   Published online June 30, 1989
Bronchiolitis is a virus.caused lower respiratory disease resulting from inflammatory obstruction of the small airways. The condition may develop to asthma anddifferential diagnosis is not clearcut between two diseases during infancy. Measurement of the serum IgE concentration has been used as an aid in the differential diagnosis. The purpose of this study is to compare the serum IgE levels between control groups and bronchiolitis patients,...
