Insights
Antihistamine use in children with non-alcoholic fatty liver disease (NAFLD) is associated with increased BMI percentiles and z-scores. This finding suggests a link between antihistamines (AH) and childhood obesity progression.
Area of Science:
- Pediatrics
- Gastroenterology
- Metabolic Health
Background:
- Childhood obesity and non-alcoholic fatty liver disease (NAFLD) are rising public health concerns in the US.
- Animal studies suggest histamine blockade may influence weight gain and hepatic steatosis.
Purpose of the Study:
- To investigate the association between antihistamine (AH) use and obesity in children diagnosed with NAFLD.
- To analyze the impact of AH on body mass index (BMI) changes over time.
Main Methods:
- Retrospective cohort study of 32 children with NAFLD from January 2018 to April 2019.
- Participants were divided into antihistamine users (n=13) and antihistamine-naïve (n=19) groups.
- Demographics, medication use, and BMI metrics were assessed.
Main Results:
- Antihistamine users showed a significant increase in BMI percentile per year (1.17 vs. -0.06, p=0.0008).
- AH usage correlated with a higher mean increase in BMI z-score per year (0.23 vs. -0.012, p=0.0016).
- No significant differences were observed in triglycerides, glucose, or liver enzymes between groups.
Conclusions:
- Antihistamine use in children with NAFLD is associated with increased BMI percentiles and z-scores over time.
- This suggests a potential role for antihistamines in the progression of childhood obesity.
- Further research is warranted to explore the mechanisms underlying this association.
Abstract:
The prevalence of childhood obesity has increased over the years in the United States and contributed to a rise in metabolic syndrome and non-alcoholic fatty liver disease (NAFLD). Animal studies suggested the role of histamine blockade on mesenteric lymphatics tone, contributing to weight gain and hepatic steatosis. This study aimed to investigate an association between antihistamines (AH) use in children and obesity. A single-center retrospective cohort study on children with a diagnosis of NAFLD, followed in the gastroenterology clinic, was performed between January 2018 and April 2019. The demographics, medications, and body mass index (BMI) were assessed. Participants were divided into an AH group with documented use and comparison group, antihistamine naïve. Of the 32 participants in the study, 13 used AH, and 19 did not. Antihistamine users had a mean increase in BMI percentile per year of 1.17 compared to a decrease of 0.06 in comparison group (p = 0.0008). AH usage correlated with a mean increase in BMI z-score of 0.23 per year, as opposed to a decrease by 0.012 in comparison group (p = 0.0016). No difference was found in triglycerides (TG), glucose, and liver enzymes. AH use increases BMI percentiles and z-scores over time and is associated with obesity in children.

Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
