An increased prevalence of behavioral problems has been described among children with asthma.
This Turkish study included 400 children with asthma. They were assessed for the following behavioral problems:
- attention deficit-hyperactivity disorder (ADHD)
- attention deficit (AD)
- hyperactivity and impulsivity (HI)
- oppositional defiant disorder (ODD)
Prevalences of AD, hyperactivity, ADHD, and ODD were not significantly different between the study and control groups.
Among those patients receiving leukotriene antagonist (LTRA) drugs adjunctive to inhaled corticosteroids (ICS), duration of treatment was correlated with hyperactivity (P = 0.03), AD (P = 0.04), ADHD (P = 0.042), and ODD (P = 0.03).
Patients with asthma receiving LTRA abd ICS treatment had a higher risk for oppositional behavior (4 times compared with the control group (P = 0.04) and 8 times compared with patients with asthma not using any drug (P = 0.02).
The authors concluded that tather than asthma itself, adjunctive use of ICS+LTRA therapy appears to be related with symptoms of common behavioral problems, including hyperactivity, AD, ADHD, and ODD and to increase the risk of ODD.
However, most of the p values in this study were marginally significant, with large confidence intervals, and I would not put too much emphasis on the results until I see more convincing evidence of causation, rather than association.
