Genotyping women before pregnancy to prevent congenital heart defects induced by serotonin reuptake inhibitors? Personalized vs pragmatic medicine

Nembhard et al’s robust study showing genetic variants in folate, homocysteine, or transsulfuration pathways are associated with congenital heart defects among children of women taking selective serotonin reuptake inhibitors (SSRI) deserves comment.

First, kudos for their concern as the safety of drugs in this most vulnerable population is characterized by the paucity of investigations, even when serious adverse effects are documented.(2,3)

Second, this physio-pathological study may be missing the wood for the trees.

a) The efficacy of antidepressant during pregnancy deserves a re-evaluation. There are no adequate and well-controlled studies in pregnant women.(4) This issue cannot be by passed as: a) numerous trials deliberately misrepresented findings;(5-6) b) the efficacy of antidepressant is not observed in several specific population such as children and adolescents, chronic heart failure or alcohol use disorders.(7-11)
b)
c) Congenital anomalies are the tip of the iceberg. SSRI also increased the risk of postpartum haemorrhage and, serious concerns for child's development are increasing (eg. autism spectrum, and attention deficit disorders).(4)
d)
Drugs should not be the first option for any woman of childbearing age (teratogenicity can occur before women are aware they are pregnant): cognitive behavioural therapy (CBT) is effective against major depression without adverse effects.(2) There is an urgent need to extend an appropriate regulation (restricting prescription in women of childbearing age to specialists who must obtain signed consent) as recently done for epilepsy.(3)
