Clinical management of perinatal anxiety disorders: A systematic review

BACKGROUND

In the last few decades, there has been a growing interest in anxiety disorders (AnxD) in the perinatal period. Although AnxD are diagnosed in 4-39% of pregnant women and in up to 16% of women after delivery, evidence on their clinical management is limited.

METHODS

A systematic review was conducted on pharmacological and non-pharmacological treatment of AnxD in the perinatal period. Relevant papers published from January 1st 2015 were identified searching the electronic databases MEDLINE, Embase, PsycINFO and the Cochrane Library.

RESULTS

18 articles met inclusion criteria. Selected studies supported the use of cognitive-behavioural therapy (CBT) for obsessive-compulsive disorder (OCD), panic disorder (PD) and specific phobia both in pregnancy and postpartum. Selective serotonin reuptake inhibitors (SSRIs) led to significant OCD and PD improvement both in pregnancy and postpartum with no side effects for the babies. In the largest clinical sample to date, 65% of postpartum patients who entered the open-label trial of fluvoxamine (up to 300mg/day) experienced a 30% or greater decrease in the total score of the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). During pregnancy, SSRIs and tricyclic antidepressants (TCAs) led to remission of panic symptoms and healthy outcomes for the babies.

LIMITATIONS

Study design, mostly case reports, and enrolment of subjects mainly from outpatient specialty units might have limited community-wide generalisability.

CONCLUSIONS

Keeping in mind the scantiness and heterogeneity of the available literature, the best interpretation of the available evidence appears to be that CBT should be the first treatment offered to pregnant and breastfeeding women with AnxD. However SSRIs can represent a first line treatment strategy, and not exclusively in cases where AnxD is refractory to CBT.

The safety of escitalopram during pregnancy and breastfeeding: a comprehensive review

OBJECTIVE

Escitalopram (ESC) is considered one of the most effective selective serotonin reuptake inhibitors for the treatment of major depression. However, little is known on its potential risk of inducing major malformations (MMs) and perinatal complications (PCs). Hence, aim of the present study is to provide a comprehensive review of the available literature on the safety profile of ESC during pregnancy and breastfeeding.

METHODS

MEDLINE and PubMed databases were searched for English language articles by using the following keywords: escitalopram, selective serotonin reuptake inhibitors, major malformations, perinatal complications, pregnancy, and breastfeeding.

RESULTS

Although some cases of MMs have been reported after maternal exposure to ESC during early pregnancy, the rate of these adverse events is substantially in the range of those reported in unexposed women. On the contrary, exposure to ESC seems to be significantly associated with some PCs. No adverse effects have been reported in the few studies evaluating its safety during breastfeeding.

CONCLUSIONS

The available data seem to support the notion that ESC might be considered safe during pregnancy, in particular as far as MMs is concerned. However, similar to other selective serotonin reuptake inhibitors, it could be associated with an increased risk of PCs. Given the paucity of the studies published so far, no definitive conclusions can be drawn on its safety profile during breastfeeding.

Drug treatment for mood disorders in pregnancy

PURPOSE OF REVIEW

During the last few years, several researches, often showing contradictory findings, have investigated the safety of psychotropic medications used for treating mood disorders in pregnancy. Hence, the necessity exists to update this information constantly in order to ensure the safest option for the mother-infant pair.

RECENT FINDINGS

The risk of fetal anomalies associated with early in-utero exposure to antidepressants seems to be increased after paroxetine and clorimipramine exposure, whereas prenatal exposure to nearly all antidepressants is linked to the potential onset of the Prenatal Antidepressant Exposure Syndrome. As regards classic mood stabilizers, the teratogenic risk historically reported with lithium should probably be softened, whereas valproate is the medication which shows the strongest association with fetal anomalies. An increased risk of autism-spectrum disorders and infant neurodevelopmental delay is also associated with valproate exposure through the placenta. No significant reproductive safety data are available on atypical antipsychotics, although such medications may indirectly increase the rate of fetal malformation by inducing gestational diabetes.

SUMMARY

Avoiding the use of clorimipramine, paroxetine, valproate, and atypical antipsychotics during pregnancy is advisable. However, when starting or continuing pharmacological treatment during pregnancy, clinicians should consider not only the intrinsic iatrogenic risk of birth defects or perinatal complications, but also the general safety profile for the expectant mother. Indeed, specific adverse reactions (such as nausea, vomiting, constipation, and excessive weight gain) may aggravate the classic clinical findings of pregnancy, thus indirectly facilitating the occurrence of pregnancy complications and fetal and neonatal problems.

Pregnancy exposure to serotonin reuptake inhibitors and the risk of spontaneous abortions

INTRODUCTION

A growing number of studies have suggested that maternal exposure to post-tricyclic antidepressants during pregnancy might be associated with an increased risk of poor birth, obstetrical, and neonatal outcomes. Among these complications, the occurrence of spontaneous abortions represents one of the most dramatic events for the pregnant woman.

METHODS

The purpose of this study was to review all studies reporting primary data investigating the rate of spontaneous abortions in women treated with selective serotonin reuptake inhibitors during pregnancy. Medical literature information published in English since 1980 was identified using MEDLINE/PubMed, TOXNET, EMBASE, and The Cochrane Library. Searches were performed using various combination of search terms and were last updated May 2008. No other limitations were imposed. Twelve articles reporting primary data on the rate of spontaneous abortions in women treated with selective serotonin reuptake inhibitors or serotonin-norepinephrine reuptake inhibitors during early pregnancy outcome of pregnancies exposed to antipsychotics were selected for the review. The author was the only reviewer who performed selection and data extraction.

RESULTS

Information from reviewed studies are scarce and methodologically inadequate to draw definitive conclusions about the hypothesized risk of spontaneous abortions associated with serotoninergic antidepressant exposure during early pregnancy.

CONCLUSION

Alternative parameters may be considered in choosing the safest serotoninergic antidepressant for the pregnant woman. Such parameters are mainly represented by the teratogenic risk associated with some of such medications and their well-known liability of inducing perinatal complications.
