Although the prevalence of bipolar disorder is equal among men and women, the course of illness and clinical features differ across sexes. Women are more likely to have hypomanic episodes and carry a diagnosis of bipolar II disorder (BD II), whereas men are more likely to experience manic episodes (Baldassano et al. 2005; Schneck et al. 2008). Compared with men, women with BD II have more frequent depressive episodes. Women with bipolar I disorder (BD I) are more likely than men to rapidly cycle and have increased episode severity over time (Erol et al. 2015). Additionally, women with both BD I and II attempt suicide more often than men (Baldassano et al. 2005). These sex-related clinical differences most likely derive from neural impacts of sex steroid fluctuation during women’s reproductive years (Brunton and Russell 2008). In the sections that follow, we address what is known about the impact of female sex steroid fluctuations on the epidemiology, clinical presentation, and treatment of BD II in reproductive-aged women.



Bidirectional Relationship of Bipolar Disorder and Menstrual Cycles


Menarche


There are inconsistent reports that earlier onset of menarche is associated with earlier onset and greater severity of mood disorder psychopathology. In the largest study to examine this association in bipolar disorder, this was confirmed for BD I but not BD II. Illness onset within 1 year before or after menarche accounted for 8.5% of women with BD I, but only 4.5% of women with BD II (Tondo et al. 2017). A smaller study (Freeman et al. 2002) found that bipolar disorder illness onset was more likely to occur before or within a year of menarche in 50% of affected women; however, these results might be influenced by the predominance of BD I in the sample (n=36, vs. BD II, n=13).


Menstrual Cycle Dysfunction


Menstrual cycle dysfunction, present in 20% of the general population, is defined as unpredictable cycle length or cycle length <25 days or >35 days. The medical implications of menstrual cycle dysfunction include infertility, osteoporosis, and endometrial hyperplasia. Early-onset menstrual cycle dysfunction, occurring within the first 5 years postmenarche and prior to any long-term impact of psychotropics, was more prevalent in women with bipolar disorder (34.2%) relative to healthy control women (22%) and women with major depressive disorder (MDD; 25%) (OR=1.7; 95% CI, 1.1–2.4; Joffe et al. 2006b). Menstrual cycle dysfunction was threefold higher in BD I relative to BD II or bipolar disorder not otherwise specified (BD NOS).


Fertility


When incidence rate ratio (IRR) for first child was used as measure of fertility, women with bipolar disorder had reduced fertility (IRR=0.36) compared with women with MDD (IRR=0.57) and other nonpsychotic psychiatric disorders (IRR=0.70) that was not explained by increased rates of therapeutic abortion. This effect was accentuated within the 18-month period following initial psychiatric hospitalization and in more severe illness (i.e., schizophrenia), which suggests that illness severity might explain reduced fertility rates (Laursen and Munk-Olsen 2010).



Several mood stabilizer agents, most notably valproic acid, first-generation antipsychotics (FGAs), and risperidone, further contribute to reduced fertility. Women exposed to valproic acid are at risk for developing polycystic ovarian syndrome either through direct effects on ovarian function or via weight gain and associated insulin resistance (Joffe et al. 2006a). Diminished fertility can also arise from FGA-mediated tuberoinfundibular dopamine2 receptor blockade, subsequent hyperprolactinemia, and ultimately suppression of ovulation. Second-generation antipsychotics (SGA) do not increase prolactin levels to the extent that FGAs do, with the exception of risperidone (Kinon et al. 2003). Because there is a limited role for valproic acid, FGAs, and risperidone in the treatment of BD II, it is conceivable that women with BD II have lower exposure to these medications and thus might be at lower risk for medication-induced infertility.


Menstrual Cycle Effects on Mood in Bipolar Disorder


Converging evidence points to a predilection for menstrual cycle–related mood worsening in BD II relative to BD I or other mood disorders. Premenstrual dysphoria was reported to be more frequent in women with BD II (70%) relative to BD I (44%) and MDD (42%) (Endicott et al. 1985). Perimenstrual mood worsening was also reported to be higher in women with BD II relative to those with BD I in a specialized bipolar disorders clinic (Perich et al. 2017). In the STEP-BD substudy (Dias et al. 2011), in which BD II represented 50% of the sample, premenstrual worsening in bipolar disorder was a predictor of more severe course of bipolar disorder illness, with more episodes per year, shorter time to subsyndromal relapse, and higher mood disorder severity. In a review of the case literature, authors described a heterogeneous temporal pattern of symptoms with respect to the menstrual cycle, with entrainment of either depressed or hypomanic mood not only to the premenstrual phase but also to the menstrual and periovulatory phases, as well as timing variability across cycles in the same woman (Teatero et al. 2014).


Lamotrigine pharmacotherapy added to a baseline medication regimen, for menstrually entrained mood symptoms, was conducted in an open-label study of women with bipolar disorder (n=23 for BD I; 24 for BD II; 25 for BD NOS). Self-reported mood was most depressed during the menstrual phase of the cycle; the depressive symptoms attenuated with lamotrigine treatment. Additionally, within-phase mood variability diminished with lamotrigine augmentation (Robakis et al. 2015). Combined oral contraceptives (COCs) were also noted to attenuate premenstrual symptoms in bipolar disorder (Rasgon et al. 2003).


Treatment recommendations for premenstrual mood symptoms occurring in the context of bipolar disorder endorsed by one group (Smith and Frey 2016) include optimization of mood stabilizer treatment followed by 2 months of prospective mood charting in order to confirm a premenstrual dysphoric disorder diagnosis. Hormonal agents, rather than antidepressants, are recommended as adjunctive treatment, in addition to lifestyle changes, psychoeducation, and cognitive-behavioral therapy, although behavioral trials for premenstrual dysphoric disorder in BD are lacking.



Case Report: Role of Hormonal Agents in the Management of Mood Symptoms Related to the Menstrual Cycle in BD II


Latasha is a 36-year-old woman with BD II who presents with premenstrual mood worsening despite treatment with quetiapine 200 mg nightly. In addition to irritable mood, her premenstrual symptoms include severe cramping, high levels of worry, irrational ideas about social rejection, and somatic symptoms of anxiety such as chest tightness, pit in stomach, and insomnia. She often misses work or incites conflict in relationships during the premenstrual period. Mood and functioning are better after onset of menses.


Her psychiatrist discusses treatment options, including the addition of a selective serotonin reuptake inhibitor (SSRI), dosed premenstrually, or the addition of the COC levonorgestrel 0.1 mg and ethinyl estradiol 0.02 mg. Because Latasha is concerned that the SSRI will worsen her irritability, as has happened in the past, she opts for the COC. In addition, the psychiatrist recommends that she meet regularly with a therapist to develop skills to manage her premenstrual mood dysregulation.


Latasha returns to the clinic 2 months after beginning the COC and engaging in regular psychotherapy. She reports a decrease in premenstrual anxiety, irritability, sleep problems, and cramps. Her boyfriend reports that she is less angry and that she has not missed any days of work.


This case illustrates the role of COCs as part of the larger armamentarium for stabilization of mood symptoms across the menstrual cycle in BD II, in conjunction with a mood stabilizer and behavioral strategies for management of BD II.



Interaction of Mood Stabilizers With Hormonal Contraception


Several of the antiepileptic drug (AED) mood stabilizers interact bidirectionally with COCs and may result in the therapeutic failure of either drug (Reimers et al. 2015). The most common estrogen in COCs, 17α-ethinyl estradiol, lowers lamotrigine plasma concentrations via potent induction of uridine 5′-diphosphate-glucuronosyltransferase (Christensen et al. 2007). Therefore, in lamotrigine-treated women, hormonal contraception options are limited to progestogen-only contraceptives, the levonorgestrel-releasing intrauterine device (LNG-IUD), or the copper-bearing IUD. Carbamazepine and topiramate induce metabolism of estrogens and progestogens; therefore, women taking these AEDs can safely use depot medroxyprogesterone acetate, LNG-IUD, and the copper-bearing IUD, but risk reduced contraceptive effectiveness with COCs, combined transdermal patch, combined contraceptive vaginal ring, progestin-only pill, norethisterone enanthate injectable, levonorgestrel, and the etonogestrel implant (Reimers et al. 2015).


Perinatal Period


Antenatal Course of Bipolar II Disorder


Onset of bipolar disorder typically occurs during women’s reproductive years. The point prevalence of BD II or hypomania at 12-weeks gestation ranges from 0.3% to 1.4%, which mirrors the 0.8%, 12-month bipolar disorder prevalence in the general population (Sharma and Pope 2012). In naturalistic studies in pregnancy, women with BD II were less likely to 1) take psychotropics beyond the first trimester (Driscoll et al. 2017; Viguera et al. 2007b), 2) receive treatment that was evidence-based (Driscoll et al. 2017), and 3) remain euthymic (Viguera et al. 2007b). Women with BD II had an 89% rate of depression/mixed recurrence versus only a 4% rate of hypomanic recurrence, whereas the polarity of recurrence for women with BD I was 41% for depressed/mixed and 20% for hypomanic or manic (Viguera et al. 2007b). Recurrence was higher with discontinuation (86% vs. 37%), particularly with abrupt discontinuation in less than 2 weeks (Viguera et al. 2007b). Reduced psychotropic use in pregnancy (46%) and higher use postpartum (73%–86%) were reported in several studies of perinatal BD (Driscoll et al. 2017; Sharma et al. 2013).



Postpartum Course of Bipolar II Disorder


The first postpartum month is a period of high risk for BD I disorder relapse and hospitalization (Munk-Olsen et al. 2006), whereas BD II episodes were more widely distributed across the perinatal period (Di Florio et al. 2013) and not reported to be associated with hospitalization. Results from a meta-analysis yielded a postpartum bipolar disorder relapse rate of 37% that did not differ between BD I or BD II (Wesseloo et al. 2016). Although there were no results available for BD II, in BD I, prophylactic pharmacotherapy compared with no medications during late pregnancy/early postpartum was associated with a reduction in the postpartum relapse rate (23% vs. 65%, respectively) (Wesseloo et al. 2016).


Recent studies have focused attention on the higher than expected prevalence of bipolar disorder in women with postpartum depression. Among 10,000 women recruited from an obstetric hospital, 22.6% of women with Edinburgh Postnatal Depression Scale (EPDS) scores of 10 or higher had a diagnosis of bipolar disorder; 50% of these women were diagnosed with BD II or BD NOS (Wisner et al. 2013). In another, small (n=56) study, 23% of women with postpartum depression were found to have lifetime BD II. Furthermore, among women unresponsive to antidepressants during postpartum depression, 54% were diagnosed with bipolar disorder, with nearly the whole group (52%) accounted for by BD NOS or BD II (Sharma et al. 2008).


Postpartum Highs

Several groups have examined the presence of hypomania in the first week postpartum by using the Highs Scale (Glover et al. 1994). The Highs Scale is a self-report scale based on DSM-III-R criteria for mania (American Psychiatric Association 1987), with a score of 2 (“Yes, a lot”) and 1 (“Yes, a little”) assigned to each of seven items (elated, more active, more talkative, thoughts raced, special talents, less sleep need, attention jumping). Using a threshold score of 8 or higher, Heron et al. (2009) reported that incidence of 1-week postpartum hypomania was approximately 12%, and surpassed the incidence of hypomania in pregnancy (1.4%) and 2 months postpartum (5%). Unlike the blues, which peak on day 3 or 4 postpartum, the highs can begin as early as day 1 postpartum. Prior to dissemination of this screening tool in the general population, further research is needed to confirm this finding in relation to standard instruments and to assess its clinical significance.



Postpartum Psychosis

Because BD II criteria exclude the presence of mixed or mania-associated psychosis, the BD II diagnosis is upheld only when psychotic symptoms accompany the depressive phase of bipolar disorder. Postpartum psychosis is rare, affecting approximately 0.1%–0.2% (1 in 1,000 to 1 in 500) of women in the postpartum period, and is considered by many to be a variant of BD I. A brief psychotic disorder phenotype may be evident, characterized by disorganized behavior and rapid shifts from excited to inhibited motoric states, from confusion to lucidity, and from anxiety/paranoia to happiness. Auditory or visual hallucinations, paranoid or grandiose delusions, and elements of delirium or disorientation are common, as are extreme deficits in judgment and high levels of impulsivity. Postpartum psychosis is a medical emergency because of the potential risk for infanticide or suicide; therefore, referral for immediate treatment in an intensive, structured setting, such as a day hospital or inpatient psychiatric unit, is indicated. Preventive and acute phase treatment strategies with lithium and antipsychotic medications were associated with favorable outcomes (Bergink et al. 2015).


Screening Considerations


Although there are no validated screening instruments for BD II (see Chapter 3, “Interface Between Borderline Personality Disorder and Bipolar II Disorder”), a number of bipolar disorder screening tools have been applied to the perinatal population. The Mood Disorder Questionnaire (MDQ; Hirschfeld et al. 2003), a 15-item self-report instrument to screen for lifetime prevalence of bipolar disorder, has shown improved sensitivity and specificity for diagnosis of perinatal bipolar spectrum diagnoses by using a score threshold of 7 in Section 1 and when removing the functional impairment criterion in Section 3 (Chessick and Dimidjian 2010). Compared with DSM-IV based clinical diagnoses, MDQ sensitivity was improved from 40% to 89% and specificity remained high (91% to 84%) with the alternative scoring algorithm (Frey et al. 2012). Another study found that the alternative scoring algorithm increased identification of bipolar disorder diagnoses by nearly 20%, from 50% to 68% (Clark et al. 2015). In these studies of 100–150 women with affective disorders, BD II diagnoses represented only 6%–10% of the total sample, and larger samples are needed for confirmation for the alternative scoring algorithm’s utility in screening for BD II.



Screening is best timed in early pregnancy, early postpartum, and at the time of a depression diagnosis. Exploring for clinical features associated with BD II has the potential to inform treatment selection and treatment course (Table 12–1). Although there is strong endorsement for perinatal depression screening in the United States (Committee on Obstetric Practice 2015; Siu et al. 2016), absence of similar directives for bipolar disorder threatens to result in high rates of undetected BD I and II.

Perinatal Treatment Considerations


With 50% of pregnancies being unplanned, women often have not considered the impact of medication and other behaviors (e.g., tobacco, alcohol) on pregnancy (Finer and Zolna 2011). Family planning discussion should occur during pharmacotherapy initiation at the time of BD II diagnosis, and ideally while the patient is euthymic. With women who are pregnant, postpartum, or planning a pregnancy, a structured discussion (Wisner et al. 2000) should include patient education regarding the natural history of her psychiatric disorder, the risks associated both with the disorder and with available somatic treatments, and a discussion of available treatment options.


Risks to mother and infant of BD II in pregnancy have not been specifically studied. In studies that did not discriminate among subtypes of bipolar disorder, both bipolar disorder (Bodén et al. 2012) and severe mental illness (Vigod et al. 2015) were associated with more adverse pregnancy outcomes relative to the general population. The most rigorous studies have methodologically adjusted for severity of illness and associated characteristics when examining impacts. Regardless of whether medication was taken in pregnancy, women with bipolar disorder were more commonly found to be smokers, to be overweight, to have misused alcohol or substances, and to have pregnancy induction, planned cesarean section, instrumental delivery, or preterm birth. Infants of women with bipolar disorder, regardless of medication exposure, were more likely to have microcephaly and neonatal hypoglycemia (Bodén et al. 2012) and tended to also be small for gestation age.


Suboptimal maternal-infant interaction can adversely impact infant socioemotional, cognitive, and physical development. Mother-infant interactional style in women with severe mental illness is noted for reduced mind-mindedness and sensitivity to infant cues. Mother-infant synchrony was greater in bipolar disorder relative to schizophrenia (Rigby et al. 2016) and was not significantly different among women with bipolar disorder (50% BD II NOS), women with MDD, and healthy control women (Logsdon et al. 2015). Reports indicate reduced emotional regulation, reduced autonomic adaptation to stressors (Johnson et al. 2014), and lower motor attainment on the Bayley Scales of Infant Development (Santucci et al. 2017) in offspring of mothers with bipolar disorder who took psychotropics in pregnancy.


Nonmedication Therapy


The perinatal period is an ideal time to optimize nonpharmacological strategies to support mental health. Close clinical monitoring and enlisting supports to prevent sleep disruption and stabilize social rhythms in the new mother with bipolar disorder are particularly important. Psychotherapy treatment options should be determined based on review of patient history, current mood state, and reference to evidence-based treatments. Interpersonal and social rhythm therapy (IPSRT; see Chapter 10, “Psychosocial Interventions in Bipolar II Disorder”) is a compelling treatment approach given demonstrated benefit of interpersonal psychotherapy in mothers (Swartz et al. 2016) and of IPSRT in women with BD II (Swartz et al. 2018). In a small RCT, a midday dose of 7,000-lux bright white light was associated with a threefold higher depression remission rate compared with red placebo light by 6 weeks in adults with bipolar depression (30% of sample with BD II) who were taking mood stabilizer agents (Sit et al. 2018). These results await replication and delineation of maintenance strategies but show promise for use as an adjunct to mood stabilizer treatment in perinatal BD II depression.


Medications During Pregnancy and Lactation


Psychotropic treatment options are determined on the basis of review of patient history, current mood state, and reference to evidence-based treatments described elsewhere in this book. A guiding principle is to optimize maternal disease management while minimizing offspring adverse effects posed by medications and maternal illness. The medication to which a mother has responded in the past is often the best choice even in the absence of substantial data, given the known risk of untreated illness. Psychotropics cross the placenta to varied extents, whereas transfer to the baby via lactation is much lower than placental transfer because of incomplete psychotropic absorption into breast milk as well as first-pass metabolism effects in the infant. If fetal exposure to a psychotropic has already occurred, this agent would be reasonable to continue during lactation rather than switching to one with theoretically lower exposure.


The benefits of breastfeeding are well established. Irrespective of incremental benefits of breastfeeding for maternal and infant sleep quality (Cubero et al. 2005; Tobback et al. 2017), the demands of caring for and feeding a newborn result in interrupted sleep. Unlike women with BD I who have a greater risk for mania because of sleep disruption, women with BD II are less susceptible to the onset of hypomania (Lewis et al. 2017). Both women with BD I and women with BD II are at risk for depressive episodes because of sleep disruption and, when available, are advised to seek assistance with overnight feedings by using either expressed breast milk or formula.



Medications pass into breast milk to varying degrees. A relative infant dose (the estimated infant dose divided by the mother’s dose in mg/kg/day) of less than 10% poses negligible risk to the infant (Newton and Hale 2015). Higher amounts of drug passage are not necessarily contraindicated, but precautions in following the infant closely should be applied. Up-to-date safety data on individual medications in lactation can be found at LactMed (http://toxnet.nlm.nih.gov).


Lithium

Since its first introduction for the treatment of mania in 1949, lithium has remained the gold standard for treatment of bipolar disorder because it is an effective prophylaxis and treatment for mania and postpartum psychosis, and it reduces the rate of rehospitalization and suicide (Bergink et al. 2016; Cade 1949; Lähteenvuo et al. 2018). For women with BD II, lithium is as effective as lamotrigine for the treatment of acute depressive episodes and is effective for maintenance therapy (Peselow et al. 1982; Suppes et al. 2008; Tondo et al. 1998). See Chapter 9, “Antidepressant Medications in Bipolar II Disorder,” for a discussion of the role of lithium in the treatment of BD II. In weighing risks and benefits of perinatal lithium treatment, women with BD II who are lithium responders must consider the risk that alternative treatments may be less effective or cause adverse effects.


The association between in utero lithium exposure and congenital malformations is lower than described previously. In an investigation of cardiac malformations in 1,325,563 pregnancies (Patorno et al. 2017), Ebsteins’s anomaly (defined as right ventricular outflow tract obstruction defects) and overall cardiac malformations occurred at a rate of 0.6 and 1.7 versus 0.18 and 1.15 per 100 births, respectively, in lithium-exposed compared with nonexposed infants.


Because of enhanced lithium clearance in pregnancy, increased serum level monitoring with appropriate dose adjustment is warranted to maintain the prepregnancy effective concentration and prevent recurrence of bipolar disorder episodes and illness exposure (Wesseloo et al. 2017). Pregnancy complications such as dehydration due to hyperemesis or preeclampsia require close lithium level monitoring because of the increased risk of toxicity. Some women taking lithium during pregnancy will develop polyhydramnios, which warrants close obstetrical evaluation but rarely requires intervention.



The case literature describes an association between late-pregnancy fetal lithium exposure and poor neonatal outcomes including poor muscle tone, tachycardia, diabetes insipidus, transient hypothyroidism, and respiratory problems. Larger studies that control for confounding variables are needed to clarify the mechanisms underlying these outcomes.


At birth, the rapid fluid shifts increase the risk for high or toxic maternal and newborn lithium concentrations. On the basis of an association between umbilical cord lithium concentrations >0.64 mEq/L and infant central nervous system, respiratory, and neuromuscular complications (Newport et al. 2005), women are advised to suspend dosing of lithium at the onset of labor or 24–48 hours prior to a scheduled delivery (i.e., cesarean section, induction) to reduce fetal passage of lithium. After delivery, the lithium dose is restarted at the prepregnancy dose to avoid large fluctuations in the serum level and to prevent toxicity in the postpartum period.


Lithium has not been associated with long-term neurodevelopmental effects based on small studies and unpublished research. In a study of 15 mothers with bipolar disorder, rigorous tests of neurological and cognitive development determined that offspring ranging from 3 to 15 years of age had normative development (van der Lugt et al. 2012). Unpublished data from a study using an illness-matched comparison group confirm these findings (Viguera 2006).


Complications such as cyanosis, hypothyroidism, and lithium toxicity have been reported in cases of infants exposed to lithium in breast milk; however, larger studies are needed to better understand the prevalence of these outcomes (Skausig and Schou 1977; Tunnessen and Hertz 1972). Case reports are confounded by the exposure to lithium during pregnancy, polypharmacy, and toxic maternal concentrations. Several studies dispel the notion that lithium should be contraindicated during breastfeeding. These studies report average infant lithium concentrations to be 20% relative to maternal lithium concentrations and provide recommendations for infant monitoring (Bogen et al. 2012; Viguera et al. 2007a). Formula supplementation should be considered in infants that are born prematurely, have an infection, or have difficulty feeding.


Antipsychotics

Few studies have specifically examined antipsychotics in the treatment of perinatal BD II. A retrospective chart review of 18 women with postpartum BD I, BD II, or BD NOS treated with quetiapine (median dose 75 mg) found that at the end of 8 weeks of treatment, 83% were rated as “much” or “very much” improved (Sharma et al. 2015). In an open-label study of quetiapine extended-release for the treatment of BD II postpartum depression (n=26), 15 women completed the study, with depression remitting by week 12 at a mean total daily dose of 137.5 mg (Misri et al. 2015).


Changes in the activity of the hepatic cytochrome P450 (CYP) enzyme system are prominent in pregnant women. The activity of CYP1A2 decreased, which resulted in reduced clearance of olanzapine or clozapine. Increased activity occurs for CYP2D6 (e.g., greater clearance of risperidone) and CYP3A4 (e.g., greater clearance of lurasidone) (Greenberg and Citrome 2017; Tsutsumi et al. 2001; Wadelius et al. 1997). Dosage adjustments are needed to maintain stability or to prevent emergent side effects.


Because of lack of differentiation among bipolar disorder subtypes in the literature, guidance for women with BD II is extrapolated from the larger bipolar disorder literature. In a sample of 1,360,101 pregnant women, approximately 35% of whom had bipolar disorder, rigorous statistical methods were applied to examine risk of major congenital malformations and cardiac malformations associated with in utero antipsychotic exposure (Huybrechts et al. 2016). The authors reported no significant increase in risk of major malformations for SGAs (relative risk [RR]=1.05; 95% CI=0.96–1.16) or FGAs (RR=0.90; 95% CI=0.62–1.31) nor any significant increase in risk of cardiac malformations for SGAs (RR=1.06; 95% CI=0.9–1.24) or FGAs (RR=0.75; 95% CI=0.39–1.43). Analyses of specific medications within SGA and FGA classes revealed similar results, with the exception of risperidone, for which there was a small but significantly increased risk of major congenital malformations (RR=1.26; 95% CI=1.02–1.56) (Huybrechts et al. 2016).


The efficacy of quetiapine for BD II depression provides a clinical rationale for this medication choice in some women, despite the association between SGAs and maternal weight gain, hyperlipidemia and increased insulin resistance, infant macrocephaly, and large-for-gestation-age infants (Bodén et al. 2012). Other risk considerations with the antipsychotic medication class include preterm birth, increased rate of higher level nursery admission, respiratory distress, and neonatal adaptation symptoms; however, larger studies are needed to disentangle effects of drug from those of illness (Kulkarni et al. 2014). Similarly, in small studies uncontrolled for diagnosis or focused on schizophrenia, gestational antipsychotic exposure was associated with lower neurodevelopmental ratings within 6 months following antipsychotic exposure (bipolar disorder was present in 32% of exposed pregnancies) (Johnson et al. 2012), with ratings recovering by 12 months of life (Peng et al. 2013). Lactational SGA relative infant dose levels below 10% make this group of medications increasingly acceptable during lactation; however, additional research is needed (Uguz 2016).


Antiepileptic Drugs

The AEDs lamotrigine, valproic acid, and carbamazepine are U.S. Food and Drug Administration (FDA)–approved long-term maintenance options for treatment of bipolar disorder. Valproic acid is the AED associated with the highest risk of major congenital malformations (10.7%) and thus reserved for perinatal women with highly refractory bipolar disorder. Carbamazepine is also a less preferred option in pregnancy because of an increased risk of major congenital malformations (4.6%) (Meador et al. 2008). Late-gestational exposure to carbamazepine has been variably associated with reduced fetal head growth, hyperbilirubinemia, and intrauterine growth restriction, but these findings are inconsistent.


Lamotrigine is a preferred option for women of childbearing age because of its favorable reproductive profile and its efficacy to prevent recurrent depressive episodes and the onset of postpartum depression in women with BD II (Campbell et al. 2014; Cunnington et al. 2011; Hernández-Díaz et al. 2012; Sharma and Sommerdyk 2016; Tomson et al. 2011). In 2008, the North American Lamotrigine Registry reported a relative risk of 10.4 for isolated cleft palate, isolated cleft lip, and combined cleft lip and palate for infants born to mothers who took lamotrigine monotherapy during pregnancy (Holmes et al. 2008); however, these findings were not reproduced in a population-based case-control study completed in 2016 (Dolk et al. 2016). Other lamotrigine registries report a rate of 2.0%–2.9% risk of cleft palate, which is consistent with the rate in the general population (Campbell et al. 2014). Lamotrigine has not been associated with other adverse effects related to pregnancy exposure.


Off-label AEDs such as gabapentin and topiramate have not been shown to be effective antimanic agents or superior monotherapy options compared with FDA-approved options.



Lamotrigine and carbamazepine are not associated with long-term neurodevelopmental abnormalities (Pariente et al. 2017). Although a delay in verbal ability has been reported for children exposed to carbamazepine during pregnancy, other investigations have concluded that children with carbamazepine exposure in utero do not differ in verbal IQ from those without exposure (Baker et al. 2015; Gaily et al. 2004). In contrast, children with in utero valproic acid exposure have significant language delays, and lower verbal IQ, and more often have clinical presentations that meet the criteria for intellectual disability (Bromley et al. 2009).


The transfer of AED to breast milk is less than the transfer during gestation. Infant/maternal serum concentration ratios for carbamazepine range from 0.0 to 0.7 (Kacirova et al. 2011). Infant serum concentrations for valproic acid are reported as 0.9%–2.3% of maternal serum levels (Piontek et al. 2000), which is less than those for lamotrigine infant serum concentration, which vary from 6% to 50% of the maternal serum concentration (Clark et al. 2013; Newport et al. 2008). Breastfeeding is supported for women taking carbamazepine, valproic acid, and lamotrigine; however, concerns for difficulty feeding, lethargy, or slowed growth require assessment by a pediatrician and possible laboratory assessments to test for toxic effects.


Antidepressants

There have been no studies of antidepressant efficacy for BD II depression in perinatal women. As with other BD II depressed patient groups, this decision must be weighed carefully for the individual patient (see Chapter 9, “Antidepressant Medications in Bipolar II Disorder”). On the basis of recent evidence for equipoise between mood stabilizer monotherapy, SSRI monotherapy, or the combination thereof in BD II depression (Altshuler et al. 2017), some women may elect to continue or to initiate unopposed antidepressants during pregnancy or lactation. Several articles provide discussions of decision making regarding use of antidepressants in pregnancy and lactation (Byatt et al. 2013; Weissman et al. 2004).


Benzodiazepines

Although not a primary treatment for BD II, benzodiazepines are a common adjunct to bipolar disorder treatment; however, benzodiazepines are also abused more frequently in individuals with BD II relative to those with recurrent MDD and subthreshold mania (Merikangas et al. 2008). Therefore, the risk of benzodiazepine abuse must be considered when recommending this adjunctive treatment across the lifespan, and especially in the perinatal period. Early studies described an association between first trimester benzodiazepine exposure and an increased risk of oral clefts (Iqbal et al. 2002), whereas subsequent studies in larger samples and with more rigorous study methods have challenged this finding (Dolovich et al. 1998). A recent report of an association between gestational exposure to benzodiazepines and higher rates of cesarean section delivery, neonatal low birth weight, and newborn ventilatory support was published (Yonkers et al. 2017). Neonatal withdrawal from combination regimens that included benzodiazepines was more severe than from opioids alone (Huybrechts et al. 2017) or SSRIs alone (Salisbury et al. 2016). Additionally, in utero benzodiazepine exposure was associated with long-term behavioral problems in the offspring, including anxiety, emotional reactivity, somatic complaints (Brandlistuen et al. 2017), and aggressive behaviors (Radojčić et al. 2017). Additional research that controls for confounding variables will elucidate the association between adjunctive treatment with benzodiazepines and adverse perinatal outcomes.


Conclusion


Higher prevalence of hypomania and BD II in women relative to men, as well as premenstrual symptom worsening in BD II, may be a function of heightened sex steroid hormone sensitivity in women’s reproductive years. Associations and interactions among bipolar disorder, mood stabilizer treatment, fertility (i.e., hyperprolactinemia and polycystic ovarian syndrome), hormonal contraception, and pregnancy must be understood in order to optimize family planning and mental and physical health in women with bipolar disorder.


BD II episodes are more widely distributed across the antenatal and postpartum period, whereas BD I episodes more commonly cluster within the first 4 weeks postpartum. There is a high risk of perinatal BD II depressive/mixed polarity illness relapse that can be mitigated by maintaining pharmacotherapy in the perinatal period. Early discussions of family planning are imperative because of illness and mood stabilizer effects on infant outcomes, such as preterm birth, small for gestation age, microcephaly, hypoglycemia, and poor maternal sensitivity to infant cues described in bipolar disorder and in association with mood stabilizer medications. Prescription of mood stabilizer medication with which a woman can achieve symptom remission is the central component of perinatal treatment, along with the important adjunctive roles of social support and protection of sleep. Recent studies provide reassuring data on perinatal and lactational risks for lithium, SGA, and lamotrigine treatment. Ongoing studies of perinatal pharmacokinetics, treatment efficacy, and neurodevelopmental outcomes in exposed infants promise to further inform treatment decisions for perinatal women with BD II.


KEY POINTS

image


  • Women with bipolar II disorder (BD II) are more likely to experience menstrual cycle–related mood worsening relative to those with bipolar I disorder (BD I) and major depressive disorder.
  • Bipolar spectrum disorders account for 11%–23% of women with postpartum depression and up to 50% of antidepressant-refractory women with postpartum depression.
  • In pregnancy, women with BD II relative to BD I are more likely to stop medication by the second trimester, experience episode recurrence, and have depressive/mixed relative to hypomanic recurrences.
  • Because of the adverse impact of mental illness on fetal development and offspring outcomes, prescription of mood stabilizer medication with which a woman can achieve symptom remission is the central component of perinatal BD II treatment, along with social support and protection of sleep.
