Approximately thirty percent of women experience depression and/or anxiety during pregnancy. In mild cases, women can manage their symptoms with therapy, environmental manipulation, exercise, social support networks, support groups, and other non-pharmacologic therapies. The first and most indicative symptom is a depressed mood that lasts throughout the day and extends beyond two weeks in duration. Women also experience a loss of interest in everyday activities and feel little pleasure in activities that would normally be enjoyable. Symptoms will often extend into the postpartum period and can negatively affect the health of the mother and child. In some cases, the woman will have a pre-existing condition that is enhanced during pregnancy. In other instances, the patient will experience a pregnancy-induced case of anxiety. In these instances, it is common for the woman to present with either panic disorder, obsessive-compulsive disorder, or generalized anxiety disorder. However, many of these medications can be detrimental during pregnancy and the post partum period as they can pose a risk to the fetus and/or newborn child. With some medications, the risk of developing teratogenesis (congenital malformations) from exposure to psychiatric medications is very high. The deformities can include cleft lip or palate, or major deformations of the organs in the fetus. Teratogenesis the baseline incidence of major congenital malformations in newborns born in the United States is estimated to be between 2 and 4%. During the earliest stages of pregnancy, formation of major organ systems takes place and is complete within the first 12 weeks after conception. Therefore, discussion around risks of exposures during pregnancy may be broken down, by the timing of exposure or trimester, with particular vigilance around first trimester exposures. For each organ or organ system, there exists a critical period during which development takes place and is susceptible to the effects of a teratogen. For example, neural tube folding and closure, forming the brain and spinal cord, occur within the first four weeks of gestation. Most of the formation of the heart and great vessels takes place from four to nine weeks after conception, although the entire first trimester is often considered pertinent. Neonatal Neonatal toxicity or perinatal syndromes (sometimes referred to Symptoms as neonatal withdrawal) refer to a spectrum of physical and behavioral symptoms observed in the acute neonatal period that can be attributed to drug exposure at or near the time of delivery. Anecdotal reports that attribute these syndromes to drug exposure must be cautiously interpreted, and larger samples studied in order to establish a causal link between exposure to a particular medication and a perinatal syndrome. Long-Term Although the data suggest that some medications may be used Effects safely during pregnancy if clinically warranted, our knowledge regarding the long-term effects of prenatal exposure to psychotropic medications is incomplete. While exposures to teratogens early in pregnancy may result in clear abnormalities, exposures that occur after neural tube closure (at 32 days of gestation) may produce more subtle changes in behavior and functioning. To date, few studies have systematically investigated the impact of exposure to psychotropic medications in utero on human development and behavior, such as the risk for cognitive or behavioral problems later in the development of children exposed to an antidepressant medication in utero. There are also a number of complications that can occur during the postpartum period. If a woman is breastfeeding, the risk of transmitting the medication through the breast milk is high. The following Table V includes a list of the most common medications used to treat mental health issues, as well as their potential complications (during pregnancy and while breast feeding):75,78 Table V. Anti A relatively small number of cases of first trimester exposure to depressants antidepressants have been reported, but these reports have suggested no increased risk of birth defects. Since there have probably been millions of cases of accidental first trimester exposure in the over thirty years of treatment with tricyclic antidepressants, the lack of reports suggesting teratogenicity is encouraging. Prozac is the most prescribed antidepressant in the United States and has been the most researched. These symptoms, however, resolve within 1 to 4 days after birth without any specific medical intervention. The best long-term study of antidepressant-exposed fetuses followed 80 cases up to age seven. Of all the antidepressants, fluoxetine (Prozac) is the best characterized antidepressant. There has been particular controversy around paroxetine use in pregnancy, as past reports have suggested that first trimester exposure to paroxetine was associated with an increased risk of cardiac defects including atrial and ventricular septal defects. Other published studies have not demonstrated increased teratogenicity of paroxetine. Importantly, independently conducted meta-analyses of available data sets have consistently found a lack of association between paroxetine exposure and cardiovascular malformations. Three prospective and more than ten retrospective studies have examined the risk of organ malformation in over 400 cases of first trimester exposure to tricyclic antidepressants. The most recent information from the Bupropion Pregnancy Registry maintained by the manufacturer GlaxoSmithKline includes data from 517 pregnancies involving first trimester exposure to bupropion. While the information above regarding the overall risk of malformation is reassuring, earlier reports had revealed an unexpectedly high number of malformations of the heart and great vessels in bupropion-exposed infants. A retrospective cohort study including over 1200 infants exposed to bupropion during the first trimester did not reveal an increased risk of malformations in the bupropion-exposed group of infants nor did it demonstrate an increased risk for cardiovascular malformations. With regard to the newer antidepressants, prospective data on 150 women exposed to venlafaxine (Effexor) during the first trimester of pregnancy suggest no increase in risk of major malformation as compared to non-exposed controls. To date, the literature does not include prospective data on the use of duloxetine (Cymbalta). There were no significant differences among exposed and non exposed groups with regard to rates of congenital malformations. In another report, there were no differences in malformation rates among women who took mirtazapine (Remeron) (n=104) during pregnancy as compared to women who took other antidepressants or controls exposed to known non-teratogens. While these initial reports are reassuring, larger samples are required to establish the reproductive safety of these newer antidepressants. It is estimated that at least 500 to 600 exposures must be collected to demonstrate a two-fold increase in risk for a particular malformation over what is observed in the general population. Attention has focused on a range of transient neonatal distress syndromes associated with exposure to (or withdrawal from) antidepressants in utero. These syndromes appear to affect about 25% of babies exposed to antidepressants late in pregnancy. The most commonly reported symptoms in the newborns include tremor, restlessness, increased muscle tone, and increased crying. The decision to admit a newborn to a special care nursery may represent a reasonable precaution for an infant exposed to medication in utero and may not be an indication of a serious problem. Another limitation is that few studies have attempted to assess maternal mood during pregnancy or at the time of delivery. There is ample evidence to suggest that depression or anxiety in the mother may contribute to poor neonatal outcomes, including premature delivery and low birth weight, and it is important to evaluate the contribution of maternal mood to neonatal outcomes. Importantly, neonatal effects have been reported with both untreated mood and anxiety disorders, as well as with medication, and limited studies have adequately teased out these variables. One important consideration is that discontinuation of or reductions in the dosage of medication in the latter part of pregnancy may increase the risk of postpartum depression. The postpartum period is a time of increased vulnerability to psychiatric illness and depression or anxiety during pregnancy has been associated with postpartum depression. These findings taken together bring into question whether there is an association at all and suggest that, if there is a risk, it is much lower than that reported in the original 2006 report. To date, two studies have systematically investigated the impact of exposure to antidepressants in utero on human development and behavior. The first of these studies followed a cohort of 135 children who had been exposed to either tricyclic antidepressants or fluoxetine (Prozac) during pregnancy (most commonly during the first trimester) and compared these subjects to a cohort of non exposed controls. A more recent report from the same group that followed a cohort of children exposed to fluoxetine or tricyclic antidepressants for the entire duration of the pregnancy yielded similar results. The authors concluded that their findings support the hypothesis that fluoxetine and tricyclic antidepressants are not behavioral teratogens and do not have a significant effect on cognitive development, language or behavior. Mood Maintenance treatment with a mood stabilizer can significantly Stabilizers reduce the risk of relapse in pregnant women with bipolar disorder. First trimester exposure to lithium has been associated with an increased risk of cardiovascular malformation between. Prenatal exposure to valproic acid can increase the risk of fetal malformation by up to 4%. There is limited information on the reproductive safety of other newer anticonvulsants. There is, however, increased support for the reproductive safety of lamotrigine (Lamictal). For women with bipolar disorder, maintenance treatment with a mood stabilizer during pregnancy can significantly reduce the risk of relapse. However, many of the medications commonly used to treat bipolar disorder carry some teratogenic risk when used during pregnancy. Concerns regarding fetal exposure to lithium have typically been based on early reports of higher rates of cardiovascular malformations. Compared to lithium, prenatal exposure to some anticonvulsants is associated with a far greater risk for organ malformation. First trimester use of carbamazepine (Tegretol) has been associated with a 1% risk of neural tube defect. Of all of the medications used for psychiatric disorders, the one with the greatest potential of serious birth defects is valproic acid (depakote). Factors that appear to increase the risk for teratogenesis include higher maternal serum anticonvulsant levels and exposure to more than one anticonvulsant. With a risk of neural tube defect ranging from 1 to 6%, valproic acid (depakote) is often considered one of last resort to treat mood disorders in reproductive aged women, since the risk for teratogenicity is high in very early pregnancy, before many women realize they are pregnant. Prenatal exposure to valproic acid has also been associated with characteristic craniofacial abnormalities, cardiovascular malformation, limb defects and genital anomalies, as well as other central nervous system structural abnormalities. Valproic acid exposure during pregnancy has been associated with poorer neurocognitive development in children followed to three years of age. In the same study, lamotrigine use (discussed below) did not affect neurocognitive development. While other anticonvulsants are being used more frequently in the treatment of bipolar disorder, there is limited information on the reproductive safety of these newer anticonvulsants, specifically gabapentin (Neurontin), oxcarbazepine (Trileptal), tigabine (Gabitril), levetiracetam (Keppra), zonisamide (Zonegran). However, there is a growing body of information the reproductive safety of lamotrigine (Lamictal), and this may be a useful alternative for some women. Data from the Registry did not show an elevated risk of malformations associated with lamotrigine exposure. Other data from the North-American Anti-Epileptic Drug Registry indicates the prevalence of major malformations in a total of 564 children exposed to lamotrigine monotherapy was 2. In a comparison group of 221,746 unexposed births, the prevalence rate for oral clefts was 0. However, other registries have not demonstrated such a significant increase in risk for oral clefts. If we assume that the findings from the North American registry are true, the absolute risk of having a child with cleft lip or palate is about 0. Atypical antipsychotic agents (discussed in greater detail below) are commonly used often to manage the acute symptoms of bipolar illness, as well as for maintenance treatment. While the data regarding the reproductive safety of these newer agents is limited, no studies thus far have indicated any teratogenic risk associated with this class of medications. Nursing: There have been reports of toxicity in nursing infants related to exposure to various mood stabilizers. Lithium is excreted in high levels in the breast milk and nursing infants experience large exposures. Signs of toxicity in the infant have included cyanosis, poor muscle tone, and hypothermia. There have also been concerns regarding the use of carbamazepine and valproic acid. Both medications have been associated with liver function abnormalities in adults and in some cases, hepatotoxicity. The risk of hepatotoxicity is greatest in children under the age of two, so infants exposed to these medications might be especially vulnerable. The American Academy of Pediatrics, however, has deemed both medications to be appropriate for use in breastfeeding mothers. Anti-Anxiety Benzodiazepines are commonly prescribed to people suffering Medications from anxiety disorders. Older studies suggest that there may be an increased risk of cleft lip and palate amounting to . If correct, the likelihood that a woman exposed to benzodiazepines during the first trimester will give birth to a child with this congenital anomaly remains less that 1%. No systematic data are available on the reproductive safety of other, non-benzodiazepine anxiolytic agents and hypnotic agents, therefore their use during pregnancy is not recommended. The consequences of prenatal exposure to benzodiazepines have been debated for over twenty years. Three prospective studies support the absence of increased risk of organ malformation following first trimester exposure to benzodiazepines. More controversial has been the issue of whether first trimester exposure to benzodiazepines increases risk for specific malformations. Initial reports suggested that there might be an increased risk of cleft lip and palate, however, more recent reports have shown no association between exposure to benzodiazepines and risk for cleft lip or palate. Nonetheless, the likelihood that a woman exposed to benzodiazepines during the first trimester will give birth to a child with this congenital anomaly, although significantly increased, remains less than 1%. Currently, no systematic data are available on the reproductive safety of non-benzodiazepine anxiolytic agents such as buspirone and hypnotic agents zolpidem (Ambien) and zalepion (Sonata). Anti-Anxiety Agents: Data suggests that the use of benzodiazepines exposes the nursing infant to low levels of medication and indicates a relatively low incidence of adverse events. The studies conducted have been limited, however, and further research is needed to make these claims more certain. Recent studies have shown Medications no increased risk to fetus or baby and are recommended for used during pregnancy for high-risk patients. Low-potency neuroleptic agents, however, are associated with higher risks of congenital malformations after first trimester exposure and are not recommended. There is not enough data to identify the effects of atypical antipsychotics on the fetus and are not recommended. In addition to the atypical antipsychotic medications described above, recent studies have not demonstrated teratogenic risk associated with high-or medium-potency neuroleptic medications; however, a recent meta-analysis of the available studies noted a higher risk of congenital malformations after first trimester exposure to low-potency neuroleptic agents. In clinical practice, higher potency neuroleptic agents such as haloperidol (Haldol), perphenazine (Trilafon), and trifluoperazine (Stelazine) are recommended over the lower potency agents in managing pregnant women with psychiatric illness. Atypical antipsychotic medications are increasingly being used to treat a spectrum of psychiatric disorders, including psychotic disorders and bipolar disorder, as well as treatment refractory depression and anxiety disorders. The first and largest published prospective study on the reproductive safety of the atypical agents provided reassuring data regarding the risk of malformations in the first trimester, although aripiprazole (Abilify) was not among the medications studied. Investigators prospectively followed a group of 151 women taking olanzapine (Zyprexa), risperidone (Risperdal), quetiapine (Seroquel), or clozapine (Clozapine) and compared outcomes to controls without exposure to known teratogens. While this information is reassuring, it is far from definitive, and larger studies are required to provide more information about the reproductive safety of these medications. To this end, the National Pregnancy Registry has been created to prospectively gather information regarding outcomes in infants exposed in utero to these newer atypical antipsychotic medications. While this may signal a potential problem associated with exposure to antipsychotic medications, it does not yield accurate information regarding the prevalence of an adverse event. The use of chlorpromazine has been associated with adverse symptoms including sedation and developmental delay. These events seem to be rare when medium/high-potency medications are used instead. In fact, approximately eighty five percent of women will experience some sort of disturbance in the weeks following birth. However, approximately fifteen percent of women will experience more severe cases of depression or anxiety. The postpartum psychiatric illnesses are divided into three categories ranging from least severe to most severe. Postpartum psychosis While it is common for women to experience some level of postpartum blues within the first few weeks of giving birth, in most instances the symptoms resolve themselves quickly and cause little disruption to their daily lives. In the forty-eight hours immediately following delivery, the woman experiences a significant decrease in estrogen and progesterone. However, there is no conclusive answer as to why some women experience more severe forms of postpartum psychiatric illness. It is believed that some women experience increased sensitivity to hormonal changes, which can make them more susceptible to severe postpartum mood alterations.

For a list of antibodies during late infancy, they are less useful in the the rapid tests that have been approved by the U. Food frst months of life and are not included in most current and Drug Administration, see. The test has an provided that the patient was not tested during the excellent sensitivity and specifcity, even in the frst window period. An indeterminate Western blot could mean in young infants (>10,000 copies/mL is considered early infection or, in an uninfected, exposed infant, the diagnostic). If the indeterminate pattern persists, the Western uninterrupted electricity, air conditioning, and clean blot needs to be repeated periodically for 6 months. However, appropriate early infant history, infant feeding options, and clinical assessment of diagnostic lab tests do more to ensure that exposed the infant or child. The child would remain with a C If the rapid test is not repeated and the diagnosis is staging even if all symptoms resolve. In this type of staging, the clinical others and is in danger of contracting a sudden and life stage is preceded by a T to indicate that a patient is on threatening opportunistic infection. A well designed referral system for lab samples will minimize Access confusion and allow rapid turnaround. Once a result is An understanding of what tests are required to diagnose available, it must be carefully communicated to both patients does not ensure that patients can get tested and patient and provider. Monitoring Advocacy: Opt-Out and Provider-Initiated Diagnostic testing is important to both individual Diagnostic Testing patients and the population as a whole. Careful data In addition to maximizing access to care, providers should collection will help guide patient care and help health care promote access to testing by instituting an opt-out policy. In 2006, the World Health Organization updated several easy-to-use tables for this purpose. This staging system is used in many countries to determine eligibility for antiretroviral therapy.

Two examples of unexplained severe wasting, stunting, severe malnutrition Courtesy of Nanda Sugandhi, M. Philadelphia: clinical algorithms deliver an accurate diagnosis of Lippincott Williams & Wilkins, 1999. Unfortunately, Principles of Therapy in such cases, the virus is still present in the body, and the concentration of circulating virus will increase if When to Start T erapy treatment is stopped. A 1-log change is a drop or increase resistance to these medications, in much the same way by a factor of 10. Patients who do not feel ill from In general, the larger the log drop, the stronger the sign their disease may not be motivated to take medicines. Patient The signifcance of a change in viral load varies with the motivation is important to ensure that medication age of the patient. In children 2 years and older and in adults, only adults follow standard criteria for starting medications. Issues associated with adherence should be fully assessed, discussed and addressed with the child, if age-appropriate, and caregiver before the decision to initiate therapy is made. Finally, any child ranges: infants younger than 12 months, children aged whose immune system has been compromised should be 1-4 years, and children aged 5 years or more. The rationale is that determining Adolescents are considered in the preceding section on which infants will have rapid and which will have slow adolescent and adult recommendations. Tese values have resource-limited settings (Tables 4 and 5) are similar to been adopted by the U. However, there were two deaths in the study attributed to nevirapine use, one from fulminant 52 Antiretroviral Treatment hepatitis and another from complications of Stevens between the two arms. Once Although efavirenz and nevirapine are structurally daily administration of lopinavir/ritonavir, unboosted distinct pharmaceuticals, either might cause hepato azatanavir, and both fosamprenavir and ritonavir-boosted toxicity or cutaneous reaction. When a severe cutaneous fosamprenavir reaction, such as Stevens-Johnson syndrome, has are listed by the U. A recently published review of the therapy, but also with an increased risk of myocardial subject concluded that there was insufcient evidence infarction. Tese medications established cardiovascular risk factors, and serum lipid are taken orally, one once a day (rilpivirene) and another levels, the relative rate of myocardial infarction per year twice a day (etravirine). A as Truvada) or zidovudine/lamivudine (coformulated randomized, placebo-controlled trial compared lopinavir/ as Combivir in North America and available in generic ritonavir with nelfnavir. Tere is a paucity of data on the mg/5 mL), which can be used for even smaller children. In the pediatric patients, have begun to see wider use in cohort, substantial increases in weight were seen over resource-limited settings. Low rates of drug adverse efects were As in treatment initiation, the decision to change seen, and adherence to medication and clinic visits were treatment because of failure should be put into clinical both high. Children and adults may have an initial drop in Malawi found that children taking half or one-quarter of viral load, followed by a slow increase. Adults who are responding well to treatment will maintain their Concerns have been expressed over the inaccuracy with weight and have few illnesses. Although the copies/mL to 10,000 or 20,000 copies/mL after a new cost, infrastructure, and personnel barriers are being course of treatment would be considered a treatment overcome, new methods to monitor virological efcacy success. A virus that has accumulated programs in resource-limited settings face the challenges several accessory mutations over time will be resistant to of scaling up services to meet the 2010 goal of universal therapy. Doing so is not always is less expensive and can usually be completed in 1-2 possible because some people have already received most weeks. In contrast, although this approach is not recommended because of phenotyping assays measure the ability of viruses to grow concerns about viral resistance. The defnition of failure They are more expensive and generally take 2-3 weeks is diferent for each individual. Resistance testing has several regimen may be continued even though full suppression drawbacks, however: it is costly and lacks uniform quality of viral replication is not achieved. Lopinavir/ritonavir (Kaletra) is one such boosted prone to this classwide type of cross-resistance. Table 7 potential challenges, not the least of which is the lack of lists doses and common side efects of all three classes of further regimens should the second-line regimen fail. Rates of frst taken with or without food and is available in oral year switching were low, estimated at between 1% and solution, tablets, and capsules, all of which should 15%.

Patients no more than 2 h after a meal to ensure adequate taking this medication and ritonavir have experi drug levels. Saquinavir enced intracranial hemorrhage, but no causal is always given with a ritonavir booster. Guidelines) as initial therapy in children or ritonavir have reported nausea, vomiting, and prepubertal adolescents because of lack of pediatric abdominal pain. However, several others are being prior to administering this class of medications. One of these is raltegravir (Isentress), which antagonists have the theoretical risk of decreasing the comes as a tablet and is taken orally twice daily. Each vial will supply enough medication for potentially serious side efects (Table 7). If the vial is reconstituted it must be kept practice guidelines recommend evaluating patients refrigerated and then allowed to warm to room at regular intervals while they are receiving these temperature prior to administration. Side efects experienced by the patient needles and routine rotation of injection sites should be reviewed.
