Acid-suppressants use during infancy increases childhood risk of recurrent wheeze and asthma
Massachusetts: A cohort study of children with a history of severe bronchiolitis found that the use of acid-suppressant medications during infancy increases the risk of recurrent wheeze and asthma during early childhood but is not associated with the risk of allergen sensitization in them. The article is published in The Journal of Allergy and Clinical Immunology: In Practice.
Bronchiolitis is a common respiratory infection among infants usually caused by the respiratory syncytial virus (RSV). Bronchiolitis is a risk factor in infants for developing conditions such as recurrent wheezing and childhood asthma in early childhood. Acid-suppressant medications like proton pump inhibitors (PPIs) and histamine-2 receptor antagonists (H2RAs), commonly prescribed in infancy may further increase the risk of allergic disease.
Studies have shown that Infants who are hospitalized for severe bronchiolitis and receive acid-suppressant medications may be at risk of developing the allergic disease by age 3 years. Little is known about the relationship between ASM exposure and the risk of childhood asthma and atopic conditions.
Robinson LB, Harvard Medical School, Boston, MA and his colleagues conducted a study to examine the association between infant acid-suppressant medications exposure and risk for developing recurrent wheeze, allergen sensitization, and asthma in early childhood.
Researchers used data from a diverse, multi-center, prospective cohort study of 921 infants with a history of bronchiolitis, of which, 202 (22%) were exposed to acid-suppressant medications during infancy. Acid-suppressant medications exposure (histamine-2 receptor antagonists and/or proton pump inhibitors) during infancy (age <12 months) was ascertained by parent report and medical record review. The outcomes were recurrent wheeze by age 3 years, early childhood allergen sensitization (serum specific IgE), and asthma by age 6 years. Researchers constructed multivariable Cox proportional hazards models and multivariable logistic regression models adjusting for multiple confounders.
Key findings of the study,
• Compared to unexposed children, those exposed to acid-suppressant medications were more likely to develop recurrent wheezing by age 3 years (adjusted hazard ratio 1.58) and asthma by age 6 years (adjusted odds ratio 1.66,).
• Acid-suppressant medication exposure during infancy was not significantly associated with the development of early childhood allergen sensitization (adjusted odds ratio 1.00).
The authors conclude that exposure to acid-suppressant medications during infancy does not increase the risk of allergen sensitization in early childhood but it increases the risk of recurrent wheezing and asthma in them. Clinicians should carefully consider the risks and benefits of acid-suppressant medications before considering their use in infants.
