SSRI effects in newborn

BACKGROUND: Selective serotonin reuptake inhibitors (SSRIs) are commonly used to treat depression during pregnancy. SSRIs cross the placenta, inhibit serotonin reuptake, and thereby are thought to alter central fetal serotonin signaling. Both prenatal maternal mood disturbances and in utero SSRI exposure have been associated with altered fetal and infant behavior. Resting-state functional magnetic resonance imaging has identified resting-state networks (RSNs) in newborns, reflecting functional capacity of auditory and visual networks and providing opportunities to examine early experiences effects on neurodevelopment...

BACKGROUND: There is a marked increase in the use of selective serotonin reuptake inhibitors and serotonin norepinephrine reuptake inhibitors in the last decade. Many newborns are likely to be exposed during pregnancy and labor. OBJECTIVE: We aimed to evaluate the association between exposure to selective serotonin reuptake inhibitors and serotonin norepinephrine reuptake inhibitors during pregnancy and the risk for persistent pulmonary hypertension of the newborn...

The long-term impact of selective serotonin reuptake inhibitor (SSRI) antidepressant treatment during pregnancy and postpartum on offspring outcomes is still not clear. Specifically, perinatal SSRI exposure may have long-term consequences for body weight and related health outcomes in the newborn period and beyond. This review focuses on the impact of perinatal SSRI exposure on weight using human and animal findings. The impact of maternal mood is also explored. We propose potential mechanisms for weight changes, including how early alterations in serotonin signaling may have implications for weight via changes in metabolism and motor development...

Selective serotonin reuptake inhibitors (SSRIs) are the most commonly used medications for mood and anxiety disorders, and adult neurogenesis in the dentate gyrus has been shown to be involved in the behavioral effects of SSRIs in mice. Studies have shown the varied effects of chronic treatment with SSRIs on adult neurogenesis. One such effect is the acceleration of neuronal maturation, which affects the functional integration of new neurons into existing neuronal circuitry. In this study, we labeled new neurons by using GFP-expressing retroviral vectors in mice and investigated the effect of an SSRI, fluoxetine, on these neurons at different time points after neuronal birth...

Exposure to prenatal insults has been associated with an increased risk for neuropsychiatric disorders, including depression, but the mechanisms are still poorly understood. Persistent alterations of the HPA axis feedback mechanism as well as adult impaired neurogenesis are believed to play a relevant role in the etiology of depression. In addition, growing evidence points at epigenetic reprogramming as a key factor. We have previously shown that prenatal exposure to the synthetic glucocorticoid dexamethasone (DEX) impairs neurogenesis and leads to late onset of depression-like behavior that does not respond to the SSRI antidepressant fluoxetine (FLX)...

Despite extensive studies, there still seems to be uncertainty as to the possible reproductive risk of selective serotonin reuptake inhibitors (SSRIs) and selective serotonin norepinephrine reuptake inhibitors (SNRIs) in pregnancy. We, therefore, assess the current data on the risk/benefit of SSRI use in pregnancy. As the neurodevelopmental effects of SSRIs are discussed in another paper in this issue, we will not address the possible neurodevelopmental effects. Special emphasis is given to the newer, large population-based studies...

Approximately 10% of pregnant women are prescribed antidepressant drugs (ADDs), with selective serotonin reuptake inhibitors (SSRIs) the most widely prescribed. SSRIs bind to the serotonin transporter (SERT), blocking the reabsorption of serotonin by the presynaptic neuron and increasing serotonin levels in the synaptic cleft. The serotonergic system regulates a range of brain development processes including neuronal proliferation, migration, differentiation and synaptogenesis. Given the presence of SERT in early brain development, coupled with the ability of SSRIs to cross the placenta and also enter breast milk, concerns have been raised regarding the effects of SSRI exposure on the developing foetus and newborns...

Over the last few years, several reports on the safety of antidepressants use in pregnancy have been published. Studies concerning the adverse effects of exposure to selective serotonin reuptake inhibitors (SSRI) during pregnancy on the developing foetus have indicated an increased risk of various congenital malformations and untoward effects such as poor neonatal adaptation syndrome or persistent pulmonary hypertension, but there still remain inconsistencies between various study results. This paper aims at reviewing the literature on the risks of exposure to antidepressants during pregnancy...

Use of selective serotonin reuptake inhibitors (SSRIs) is common during pregnancy. Fetal exposure to SSRIs is associated with persistent pulmonary hypertension of the newborn (PPHN); however, a direct link between the two has yet to be established. Conversely, it is well known that PPHN can be caused by premature constriction of the ductus arteriosus (DA), a fetal vessel connecting the pulmonary and systemic circulations. We hypothesized that SSRIs could induce in utero DA constriction. Using isolated vessels and whole-animal models, we sought to determine the effects of two commonly prescribed SSRIs, fluoxetine and sertraline, on the fetal mouse DA...

OBJECTIVE: The purpose of this article was to systematically compare the developmental trajectory of neurobehavior over the first postnatal month for infants with prenatal exposure to pharmacologically untreated maternal depression, selective serotonin reuptake inhibitors or serotonin and norepinephrine reuptake inhibitors (collectively: SSRIs), SSRIs with concomitant benzodiazepines (SSRI plus benzodiazepine), and no maternal depression or drug treatment (no exposure). METHOD: Women (N=184) were assessed at two prenatal time points to determine psychiatric diagnoses, symptom severity, and prenatal medication usage...

OBJECTIVE: To follow up on previously reported associations between periconceptional use of selective serotonin reuptake inhibitors (SSRIs) and specific birth defects using an expanded dataset from the National Birth Defects Prevention Study. DESIGN: Bayesian analysis combining results from independent published analyses with data from a multicenter population based case-control study of birth defects. SETTING: 10 centers in the United States...

Fluoxetine (FLX), a selective serotonin reuptake inhibitor (SSRI) is a commonly prescribed antidepressant drug in pregnant women. FLX readily crosses the placenta, consequently altering serotonergic neurotransmission in the fetus and causing physiological and behavioral disturbances in the newborn. Studies have shown that serotonin plays a role in modulating immune signaling. Thus, the goal of this study was to assess the effects of prenatal exposure to FLX on the response to an immune challenge in offspring mice...

Herbal medicines are perceived to be safe by the general public and medical practitioners, despite abundant evidence from clinical trials and case reports that show herbal preparations can have significant adverse effects. The overall impact of adverse events to herbal medicines in Australia is currently unknown. Post marketing surveillance of medications through spontaneous adverse drug reaction (ADR) reports to the Therapeutic Goods Administration (TGA) is one way to estimate this risk. The patterns of spontaneously reported ADRs provide insight to herbal dangers, especially when compared with patterns of a mechanistically similar conventional drug...

UNLABELLED: Recent information suggests that antenatal exposure to psychotropics may impair child neurodevelopment. Thus, aim of this review is to examine systematically available literature investigating potential associations between prenatal use of selective serotonin reuptake inhibitors (SSRIs) and the risk of autism spectrum disorders (ASDs). METHODS: Medical literature published in English since 1988 identified using MEDLINE/PubMed, EMBASE, SCOPUS, and The Cochrane Library...

OBJECTIVE: To assess whether use of specific selective serotonin reuptake inhibitors (SSRIs) or venlafaxine in early pregnancy is associated with an increased risk of birth defects, with emphasis on cardiovascular birth defects even when accounting for lifestyle or other familial confounding. DESIGN: Multicountry population based cohort study, including sibling controlled design. SETTING: Nordic population (Denmark, Finland, Iceland, Norway, and Sweden) identified from nationwide health registers at different periods in 1996-2010...

BACKGROUND: High mortality and morbidity rates are observed in patients with bacterial meningitis (BM) and urge for new adjuvant treatments in addition to standard antibiotic therapies. In BM the hippocampal dentate gyrus is injured by apoptosis while in cortical areas ischemic necrosis occurs. Experimental therapies aimed at reducing the inflammatory response and brain damage have successfully been evaluated in animal models of BM. Fluoxetine (FLX) is an anti-depressant of the selective serotonin reuptake inhibitors (SSRI) and was previously shown to be neuroprotective in vitro and in vivo...

The striatonigral projection is a striatal output pathway critical to motor control, cognition, and emotion regulation. Its axon terminals in the substantia nigra pars reticulata (SNr) express a high level of serotonin (5-HT) type 1B receptors (5-HT(1B)Rs), whereas the SNr also receives an intense 5-HT innervation that expresses 5-HT transporters, providing an anatomic substrate for 5-HT and selective 5-HT reuptake inhibitor (SSRI)-based antidepressant treatment to regulate the striatonigral output. In this article we show that 5-HT, by activating presynaptic 5-HT(1B)Rs on the striatonigral axon terminals, potently inhibited the striatonigral GABA output, as reflected in the reduction of the striatonigral inhibitory postsynaptic currents in SNr GABA neurons...

The paper by Robinson posits that risks from prenatal exposure to selective serotonin reuptake inhibitor (SSRI) antidepressants are not different from the risks encountered in the general population and that untoward effects of SSRIs are difficult to distinguish from those of the mood disorder. Indeed, maternal depression and anxiety can have negative consequences for fetal and postnatal development. Fortunately, experimental evidence suggests that mood and anxiety disorder symptoms often respond to psychosocial interventions...

OBJECTIVE: Given the current debate and growing public concerns on selective serotonin reuptake inhibitors (SSRIs) and birth defects generated by Food and Drug Administration warnings, we aim to quantify the association between first-trimester exposure to sertraline, a first-line treatment, and the risk of congenital malformations in a cohort of depressed women. STUDY DESIGN: This was a population-based cohort study in Quebec, Canada, 1998 through 2010. From a cohort of 18,493 depressed/anxious pregnancies, sertraline-exposed, nonsertraline SSRI-exposed, non-SSRI exposed, and unexposed (reference category) women were studied...
