Inflammation Predicts Poor Response to Fluoxetine in Kids
Inflammation upsets the balance of neurotransmitters in the brain and can make antidepressants less effective. In new research by Maya Amitai and colleagues, children and adolescents were less likely to respond to the selective serotonin reuptake inhibitor (SSRI) antidepressant fluoxetine if they had high levels of inflammation measured in the blood.
Amitai’s study included 41 patients between the ages of 9 and 18. They met criteria for a diagnosis of either major depression or an anxiety disorder. The participants were treated with the SSRI fluoxetine for eight weeks. Those with high levels of the inflammatory markers tumor necrosis factor (TNF) alpha, interleukin-6, and interleukin 1 beta were less likely to respond to the antidepressant treatment. The research was published in the Journal of Child and Adolescent Psychopharmacology in 2016.
Editor’s Note: These findings parallel those from studies of adults, suggesting that inflammation can predict poor response to antidepressants in all age groups.
