Insights
Children with herpangina face higher risks of allergic rhinitis and atopic dermatitis. Hand, foot, and mouth disease in children is linked to a lower risk of developing asthma.
Area of Science:
- Pediatric Allergy and Immunology
- Infectious Diseases
- Epidemiology
Background:
- Viral infections in infancy are associated with increased risks of respiratory conditions like asthma.
- The link between specific enterovirus infections in early childhood and the subsequent development of allergic diseases requires further investigation.
Purpose of the Study:
- To investigate the association between symptomatic enterovirus infections (herpangina and hand, foot, and mouth disease) in preschoolers and the risk of developing allergic diseases.
- To compare the subsequent risks of asthma, allergic rhinitis, and atopic dermatitis in children with a history of herpangina or hand, foot, and mouth disease.
Main Methods:
- Nationwide population-based cohort study utilizing data from the Taiwan National Health Insurance Research Database (1999-2006).
- Comparison of allergic disease incidence (asthma, allergic rhinitis, atopic dermatitis) between children diagnosed with herpangina or hand, foot, and mouth disease and a control group.
- Cox proportional hazards model was employed to analyze the risks throughout the follow-up period.
Main Results:
- Children with a history of herpangina showed a significantly increased risk of developing allergic rhinitis (aHR: 1.15, 95% CI: 1.02-1.30) and atopic dermatitis (aHR: 1.38, 95% CI: 1.17-1.63).
- Children diagnosed with hand, foot, and mouth disease exhibited a decreased risk of developing asthma (aHR: 0.76, 95% CI: 0.63-0.93).
- The study evaluated 8337 subjects, including 3267 children in the infection cohort and 5070 in the comparison cohort.
Conclusions:
- Previous herpangina infection in children is associated with a higher risk of developing atopic dermatitis and allergic rhinitis later in life.
- Hand, foot, and mouth disease in childhood may be associated with a reduced subsequent risk of asthma.
- These findings highlight potential differential impacts of enterovirus infections on the development of allergic diseases.
Abstract:
Infants who are exposed to the rhinovirus or respiratory syncytial virus are at a higher risk of subsequently developing wheezing or asthma. This study aims to determine whether preschoolers with a history of symptomatic enterovirus infection are at an increased risk of developing allergic diseases or not.We used data from the Taiwan National Health Insurance Research Database from 1999 to 2006 for this nationwide population-based cohort study. The subsequent risks for allergic diseases, which included asthma (International Classification of Diseases [ICD]-9: 493.X), allergic rhinitis (AR; ICD-9 CM code 477.X), and atopic dermatitis (AD; ICD-9-CM code 691.X), were compared between herpangina (ICD-9: 074.0) and hand, foot, and mouth disease (HFMD; ICD-9: 074.3) throughout the follow-up period using the Cox proportional hazards model.In this database, 12,016 neonates were born between January 1999 and December 1999. Among them, we further evaluated 8337 subjects; 3267 children infected with either herpangina or HFMD served as the study cohort, and the other 5070 children made up the comparison cohort. Children in the herpangina group had a higher risk of developing AR and AD, with adjusted hazard ratios of 1.15 (1.02-1.30, 95% CI) and 1.38 (1.17-1.63. 95% CI), respectively, while children suffered from HFMD had decreased risks of asthma, with an adjusted hazard ratio of 0.76 (0.63-0.93, 95% CI).Children who previously suffered from herpangina experienced an increased risk of subsequently developing AD and AR. Meanwhile, children who had suffered from HFMD experienced a decrease in the subsequent occurrence of asthma compared to the general population.
