Prevalence, comorbidities, diagnosis, and treatment of nonallergic rhinitis: real-world comparison with allergic rhinitis
Hye Yung Yum, Eun Kyo Ha, Yoon Ho Shin, Man Yong Han
Clin Exp Pediatr. 2021;64(8):373-383.   Published online August 10, 2020
Rhinitis is among the most common respiratory diseases in children. Nonallergic rhinitis, which involves nasal symptoms without evidence of systemic allergic inflammation or infection, is a heterogeneous entity with diverse manifestations and intensities. Nonallergic rhinitis accounts for 16%–89% of the chronic rhinitis cases, affecting 1%–50% (median 10%) of the total pediatric population. The clinical course of nonallergic rhinitis is generally...

Nasal eosinophilia and eosinophil peroxidase in children and adolescents with rhinitis
Yeonu Choi, Haeun Jeon, Eun Ae Yang, Jong-Seo Yoon, Hyun Hee Kim
Clin Exp Pediatr. 2019;62(9):353-359.   Published online April 24, 2019
Background: Researchers have shown that eosinophil peroxidase (EPO) is a relatively accurate marker of eosinophilia and eosinophil activity. However, its use as a marker of eosinophilic inflammation in nasal secretions is limited because the diagnostic cutoff values of EPO for use as a one-time test for allergic diseases such as allergic rhinitis have not been established.
Purpose: To identify the correlation...

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...

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.

Methods

Methods

Second grade students at elementary schools (11 schools in Incheon and 45 schools in...

Purpose

To compare the profiles of the bronchodilator response (BDR) among children with asthma and/or allergic rhinitis (AR) and to determine whether BDR in these children is reduced by treatment with inhaled and/or nasal corticosteroid.

Methods

Sixty-eight children with asthma (mean age, 10.9 years), 45 children with comorbid asthma and AR (mean age, 10.5 years), and 44 children with AR alone (mean age,...

Hyun Hee Kim
Clin Exp Pediatr. 2007;50(4):335-339.   Published online April 15, 2007
The link between upper airway disease (allergic rhinitis and sinusitis) and lower airway disease (asthma) has long been of interest to physicians. Many epidemiological and pharmacological studies have provided a better understanding of pathophysiologic interrelationship between allergic rhinitis and asthma. The vast majority of patients with asthma have allergic rhinitis, and rhinitis is a major independent risk factor for asthma...
