Abstract | HYPOTHESIS: METHODS: Female nulliparous Wistar rats were given vehicle (N=15) or fluoxetine hydrochloride (FLX 10mg/kg/d; N=15) orally for 2 weeks prior to mating until weaning. We assessed glucometabolic changes and hepatic pathophysiology in the offspring. RESULTS:
Fluoxetine exposed offspring demonstrated altered glucose homeostasis without any alterations to beta cell mass. FLX-exposed offspring had a significant increase in the number of offspring with mild to moderate NASH and dyslipidemia. There was also increased inflammation of the liver in FLX-exposed offspring; males had significant elevations in TNFα, IL6 and monocyte chemoattractant protein 1 (MCP1), while female offspring had higher expression of TNFα, and increased macrophage infiltration (MCP1). LIMITATIONS: This is an animal study. Further research examining the metabolic outcomes of children exposed to antidepressants in utero are required, given the increase in childhood obesity and psychiatric medication use during pregnancy. CONCLUSION: These data demonstrate that fetal and neonatal exposure to FLX results in evidence of increased adiposity, fatty liver and abnormal glycemic control. Since these are all hallmarks of the metabolic syndrome, this raises concerns regarding the long term metabolic sequelae of fetal exposure to SSRIs in human populations.
