Abstract
Studies on drug utilization in western countries disclosed that about nine over ten women use at least one or more drugs during pregnancy. Determining whether a drug is safe or not in pregnant women is a challenge of all times. As a developing organism, the fetus is particularly vulnerable to effects of drugs used by the mother. Historically, research has predominantly focused on birth defects, which represent the most studied adverse pregnancy outcomes. However, drugs can also alter the ongoing process of pregnancy and impede the general growth of the fetus. Finally, adverse drug reactions can theoretically damage all developing systems, organs or tissues, such as the central nervous system or the immune system. This extensive review focuses on different aspects of drug-induced damages affecting the fetus or the newborn/infant, beyond birth defects, which are not addressed here.

Consensus Panel Recommendations for the Pharmacological Management of Pregnant Women with Depressive Disorders. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:6565. [PMID: 37623151 PMCID: PMC10454549 DOI: 10.3390/ijerph20166565] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/24/2023] [Revised: 08/01/2023] [Accepted: 08/07/2023] [Indexed: 08/26/2023]
Abstract
INTRODUCTION The initiative of a consensus on the topic of antidepressant and anxiolytic drug use in pregnancy is developing in an area of clinical uncertainty. Although many studies have been published in recent years, there is still a paucity of authoritative evidence-based indications useful for guiding the prescription of these drugs during pregnancy, and the data from the literature are complex and require expert judgment to draw clear conclusions. METHODS For the elaboration of the consensus, we have involved the scientific societies of the sector, namely, the Italian Society of Toxicology, the Italian Society of Neuropsychopharmacology, the Italian Society of Psychiatry, the Italian Society of Obstetrics and Gynecology, the Italian Society of Drug Addiction and the Italian Society of Addiction Pathology. An interdisciplinary team of experts from different medical specialties (toxicologists, pharmacologists, psychiatrists, gynecologists, neonatologists) was first established to identify the needs underlying the consensus. The team, in its definitive structure, includes all the representatives of the aforementioned scientific societies; the task of the team was the evaluation of the most accredited international literature as well as using the methodology of the "Nominal Group Technique" with the help of a systematic review of the literature and with various discussion meetings, to arrive at the drafting and final approval of the document. RESULTS The following five areas of investigation were identified: (1) The importance of management of anxiety and depressive disorders in pregnancy, identifying the risks associated with untreated maternal depression in pregnancy. (2) The assessment of the overall risk of malformations with the antidepressant and anxiolytic drugs used in pregnancy. (3) The evaluation of neonatal adaptation disorders in the offspring of pregnant antidepressant/anxiolytic-treated women. (4) The long-term outcome of infants' cognitive development or behavior after in utero exposure to antidepressant/anxiolytic medicines. (5) The evaluation of pharmacological treatment of opioid-abusing pregnant women with depressive disorders. CONCLUSIONS Considering the state of the art, it is therefore necessary in the first instance to frame the issue of pharmacological choices in pregnant women who need treatment with antidepressant and anxiolytic drugs on the basis of data currently available in the literature. Particular attention must be paid to the evaluation of the risk/benefit ratio, understood both in terms of therapeutic benefit with respect to the potential risks of the treatment on the pregnancy and on the fetal outcome, and of the comparative risk between the treatment and the absence of treatment; in the choice prescription, the specialist needs to be aware of both the potential risks of pharmacological treatment and the equally important risks of an untreated or undertreated disorder.

Abstract
Opioids are potent analgesics used to manage pain in both young and old, but the increased use in the pregnant population has significant individual and societal implications. Infants dependent on opioids, either through maternal or iatrogenic exposure, undergo neonatal opioid withdrawal syndrome (NOWS), where they may experience withdrawal symptoms ranging from mild to severe. We present a detailed and original review of NOWS caused by maternal opioid exposure (mNOWS) and iatrogenic opioid intake (iNOWS). While these two entities have been assessed entirely separately, recognition and treatment of the clinical manifestations of NOWS overlap. Neonatal risk factors such as age, genetic predisposition, drug type, and clinical factors like type of opioid, cumulative dose of opioid exposure, and disease status affect the incidence of both mNOWS and iNOWS, as well as their severity. Recognition of withdrawal is dependent on clinical assessment of symptoms, and the use of clinical assessment tools designed to determine the need for pharmacotherapy. Treatment of NOWS relies on a combination of non-pharmacological therapies and pharmacological options. Long-term consequences of opioids and NOWS continue to generate controversy, with some evidence of anatomic brain changes, but conflicting animal and human clinical evidence of significant cognitive or behavioral impacts on school-age children. We highlight the current knowledge on clinically relevant recognition, treatment, and consequences of NOWS, and identify new advances in clinical management of the neonate. This review brings a unique clinical perspective and critically analyzes gaps between the clinical problem and our preclinical understanding of NOWS.

Abstract
In a number of countries, the prevalence of neonatal opioid withdrawal syndrome (NOWS) is increasing. While NOWS is ultimately the result of opioid exposure in utero, a wide range of risk factors have been associated with the prevalence of NOWS, extending beyond just drug exposure. This article reviews the available literature on factors associated with the incidence of NOWS in opioid-exposed neonates. A range of risk factors have been associated with NOWS, including features of neonatal drug exposure, maternal and neonatal characteristics, aspects of labor and delivery, and genetics. Increased length of gestation and higher birth weight were consistently associated with an increased risk of NOWS, while breast feeding and 'rooming-in' were associated with a reduced risk of NOWS. Additionally, several genetic factors have also been associated with NOWS severity. There is conflicting evidence on the association between NOWS and other risk factors including opioid dose, neonate sex, and the use of some medications during pregnancy. This may be in part attributable to differences in how NOWS is diagnosed and the variety of methodologies across studies. While a large number of risk factors associated with NOWS are non-modifiable, encouraging pregnant women to reduce other drug use (including smoking), breast feed their child, and the judicious use of medications during pregnancy may help reduce the prevalence of NOWS. The presence or absence of NOWS in an opioid-exposed neonate is associated with a wide range of factors. Some of these modifiable risk factors may be potential targets for the primary prevention of NOWS.

Abstract
Depression is a common disorder in pregnancy and associated with adverse effects for both mother and neonate. Pharmacological treatment and prevention options include mirtazapine. In a series of 56 cases, we investigated neonatal outcome after intrauterine exposure to mirtazapine and exposure through lactation in the first days postpartum.No increase in any neonatal complication was observed. None of the infants exposed to mirtazapine in the first trimester were born with a major malformation. Of the 54 infants exposed to mirtazapine in the third trimester, 14 were diagnosed with poor neonatal adaptation syndrome (PNAS). This incidence (25.9%) is similar to the incidence of PNAS after intrauterine exposure to other antidepressants. The incidence of PNAS after exposure to mirtazapine was significantly diminished in children who were partially or fully breastfed (18.6% versus 54.5%, P = 0.024).

Abstract
Opioid use in pregnant women has increased over the last decade. Following birth, infants with in utero exposure demonstrate signs and symptoms of withdrawal known as the neonatal abstinence syndrome (NAS). Infants express a spectrum of disease, with most requiring the administration of pharmacologic therapy to ensure proper growth and development. Treatment often involves prolonged hospitalization. There is a general lack of high-quality clinical trial data to guide optimal therapy, and significant heterogeneity in treatment approaches. Emerging trends in the treatment of infants with NAS include the use of sublingual buprenorphine, transition to outpatient therapy, and pharmacogenetic risk stratification.

Abstract
BACKGROUND Acute limb compartment syndrome or Volkmann's ischaemic contracture is an acquired ischaemia of nerve and muscle causes by raised pressure within a closed fascial space. Congenital Volkmann's ischaemic contracture (CVIC) is a rare entity. PATIENTS AND METHODS A 2-day-old girl was referred with a problem of the left forearm and arm, which exhibited cold oedema with decreased mobility. Lesions were present at birth and were rapidly complicated by skin necrosis. The mother was taking olazanpine, prazepam and valpromide throughout the entire pregnancy. Delivery was complicated by shoulder dystocia requiring obstetric procedures such as suprapubic pressure, Couder's maneuver and episiotomy. On physical examination her left hemi-thorax, left arm, forearm and hand exhibited marked oedema. A large and well-demarcated bullous, fibrous and ulcerated area of skin necrosis was observed on the elbow fold and on the inner anterior part of the arm. Digital flexion with cyanosis was present. MR angiography revealed extensive oedema of the soft tissue and muscle with fascial effusion, associated with compression of the arm arteries and reduced blood flow in the forearm. A fasciotomy was performed at Day 3 of life. The postsurgical arterial MRI was normal. At Day 10 of life, the patient developed opisthotonos involving spasms and tremors associated with numerous intercritical abnormalities evoking benzodiazepine weaning syndrome. The child's neurological status was stabilized by treatment with phenobarbital and clonazepam. She was subsequently lost to follow-up. DISCUSSION CVIC has been ascribed to multiples causes. Mechanical compression is the main recognized factor: amniotic band constriction, umbilical cord loops, compression in utero by a deceased co-twin, malposition of the hand, arm or forearm, local or general factors that can add to extraction problems: brachypelvic disproportion, extraction with forceps, oligo/polyhydramnios, pre-term delivery, pre-eclampsia, caesarean section, premature labour, excessive maternal weight gain or diabetes. Our case emphasized three main points. First, the diagnostic value of early MR angiography in the event of associated extensive tissue oedema, multiple arterial compression and decreased vascular perfusion. Second, the role of shoulder dystocia in triggering the traumatic factor reported for the first time. Third, the role of neuroleptic and anxiolytic treatments taken by the mother during pregnancy. Prazepam is a long-acting benzodiazepine that can cause impregnation and withdraw syndromes in neonates. Impregnation "floppy infant syndrome" is an early event characterized by hypotonia, hypoventilation and lethargy. Hypotonia and decreased foetal movements may favour prolonged pressures and malposition with secondary crush injury during delivery. Maternal medication has not been cited hitherto as an aetiological factor in neonatal compartment syndrome.

Abstract
Epilepsy affects the menstrual cycle, aspects of contraception, fertility, pregnancy and bone health in women. It is common for seizure frequency to vary throughout the menstrual cycle. In ovulatory cycles, two peaks can be seen around the time of ovulation and in the few days before menstruation. In anovulatory cycles, there is an increase in seizures during the second half of the menstrual cycle. There is also an increase in polycystic ovaries and hyperandrogenism associated with valproate therapy. There are no contraindications to the use of non-hormonal methods of contraception in women with epilepsy. Non-enzyme-inducing antiepileptic drugs (AEDs) [valproate, benzodiazepines, ethosuximide, levetiracetam, tiagabine and zonisamide] do not show any interactions with the combined oral contraceptive (OC). There are interactions between the combined OC and hepatic microsomal-inducing AEDs (phenytoin, barbiturates, carbamazepine, topiramate [dosages>200 mg/day], oxcarbazepine) and lamotrigine. Pre-conception counselling should be available to all women with epilepsy who are considering pregnancy. Women with epilepsy should be informed about issues relating to the future pregnancy, including methods and consequences of prenatal screening, fertility, genetics of their seizure disorder, teratogenicity of AEDs, folic acid and vitamin K supplements, labour, breast feeding and care of a child. During pregnancy, the lowest effective dose of the most appropriate AED should be used, aiming for monotherapy where possible. Recent pregnancy databases have suggested that valproate is significantly more teratogenic than carbamazepine, and the combination of valproate and lamotrigine is particularly teratogenic. Most pregnancies in women with epilepsy are without complications, and the majority of infants are delivered healthy with no increased risk of obstetric complications in women. There is no medical reason why a woman with epilepsy cannot breastfeed her child. The AED concentration profiled in breast milk follows the plasma concentration curve. The total amount of drug transferred to infants via breast milk is usually much smaller than the amount transferred via the placenta during pregnancy. However, as drug elimination mechanisms are not fully developed in early infancy, repeated administration of a drug such as lamotrigine via breast milk may lead to accumulation in the infant. Studies have suggested that women with epilepsy are at increased risk of fractures, osteoporosis and osteomalacia. No studies have been undertaken looking at preventative therapies for these co-morbidities.

Abstract
AIMS Through a novel synthesis of the literature and our own clinical experience, we have derived a set of evidence-based recommendations for consideration as guidance in the management of opioid-dependent pregnant women and infants. METHODS PubMed literature searches were carried out to identify recent key publications in the areas of pregnancy and opioid dependence, neonatal abstinence syndrome (NAS) prevention and treatment, multiple substance abuse and psychiatric comorbidity. RESULTS Pregnant women dependent on opioids require careful treatment to minimize harm to the fetus and neonate and improve maternal health. Applying multi-disciplinary treatment as early as possible, allowing medication maintenance and regular monitoring, benefits mother and child both in the short and the long term. However, there is a need for randomized clinical trials with sufficient sample sizes. RECOMMENDATIONS Opioid maintenance therapy is the recommended treatment approach during pregnancy. Treatment decisions must encompass the full clinical picture, with respect to frequent complications arising from psychiatric comorbidities and the concomitant consumption of other drugs. In addition to standardized approaches to pregnancy, equivalent attention must be given to the treatment of NAS, which occurs frequently after opioid medication. CONCLUSION Methodological flaws and inconsistencies confound interpretation of today's literature. Based on this synthesis of available evidence and our clinical experience, we propose recommendations for further discussion.

Abstract
In experimental animals, prenatal diazepam exposure has clearly been associated with behavioral disturbances. Its impact on newborn breathing has not been documented despite potential deleterious consequences for later brain development. We addressed this issue in neonatal rats (0-2 d) born from dams, which consumed 2 mg/kg/d diazepam via drinking fluid throughout gestation. In vivo, prenatal diazepam exposure significantly altered the normoxic-breathing pattern, lowering breathing frequency (105 vs. 125 breaths/min) and increasing tidal volume (16.2 vs. 12.7 mL/kg), and the ventilatory response to hypoxia, inducing an immediate and marked decrease in tidal volume (-30%) absent in controls. In vitro, prenatal diazepam exposure significantly increased the respiratory-like frequency produced by pontomedullary and medullary preparations (+38% and +19%, respectively) and altered the respiratory-like response to application of nonoxygenated superfusate. Both in vivo and in vitro, the recovery from oxygen deprivation challenges was delayed by prenatal diazepam exposure. Finally, real-time PCR showed that prenatal diazepam exposure affected mRNA levels of alpha1 and alpha2 GABAA receptor subunits and of A1 and A2A adenosine receptors in the brainstem. These mRNA changes, which are region-specific, suggest that prenatal diazepam exposure interferes with developmental events whose impact on the respiratory system maturation deserves further studies.

Abstract
The management of the infant exposed to drugs in utero poses significant challenges. Symptoms and signs of neonatal abstinence syndrome (NAS) are non-specific but most commonly associated with withdrawal from maternal opioids. A high index of suspicion is required when presented with an infant who could be manifesting symptoms of NAS. In the absence of a reliable history of maternal drug exposure, analysis of neonatal meconium or urine may be indicated. Approximately 90% of infants exposed to opioids will exhibit signs of NAS, although a smaller proportion will require pharmacological treatment. Although few studies have evaluated the advantages of different therapeutic agents and strategies, opioid withdrawal is best treated initially with opioid medication. Supportive care of the infant should include assessment of the adequacy of feeding, evaluation of social circumstances (particularly child protection issues) and surveillance for transmission of viral infection.

Fifty three newborns were included between 1998 and 2002. Most of cases have been exposed to benzodiazepines, opioids and cannabis. Ninety two and a half per cent had a neonatal disease. Neonatal withdrawal, respiratory disease, hypotonia and hypotrophy were the most frequent neonatal pathologies. Many cases were exposed to cannabis which might increase neonatal disease risk. These results underline the impact of psychotropic use or abuse during pregnancy on neonatal outcomes.
