Intrahepatic cholestasis of pregnancy (ICP) is a complication of pregnancy resulting in elevation of serum bile acid levels. ICP is often associated with underlying liver disease, including hepatitis C. Bile acids in relationship to the acute infection of hepatitis C virus have not yet been delineated in the literature. A 26-year-old gravida 4 para 2103 with dichorionic, diamniotic twin gestation and history of intravenous drug abuse developed ICP in the setting of acute hepatitis C infection. In addition to clinical symptoms of pruritus and right upper quadrant pain, she developed severe elevation in bile acids, 239 micromol/L, and transaminitis aspartate aminotransferase 1033 U/L, and alanine aminotransferase 448 U/L...

BACKGROUND AND AIMS: The relationship between gestational age at delivery and the severity of neonatal abstinence syndrome (NAS) is poorly understood. Our objective was to compare the length of pharmacotherapy and hospital stay among opioid exposed infants born during the late preterm, early term, full term, and late term periods. DESIGN: Retrospective cohort study of infants affected by NAS SETTING: MetroHealth Medical Center in Cleveland, Ohio, USA: an urban tertiary care hospital serving as the referral center for opioid dependency in pregnancy with a level III neonatal intensive care unit PARTICIPANTS: All deliveries complicated by maternal opioid exposure from January 2000 to October 2014; 403 were eligible to be included (n = 102 Late Preterm, 34-36weeks (LP), n = 158 Early Term, 37-38weeks (ET), n = 122 Full Term, 39-40weeks (FT), n = 21 Late Term, ≥41 weeks (LT))...

Development of a healthy gut microbiome is essential in newborns to establish immunity and protection from pathogens. Recent studies suggest that infants who develop dysbiosis may be at risk for lifelong adverse health consequences. Exposure to opioid drugs during pregnancy is a factor of potential importance for microbiome health that has not yet been investigated. Since these infants are born after an entire gestation exposed to mu opioid receptor agonists and have severe gastrointestinal and neurological symptoms, we hypothesize that these infants are at risk for dysbiosis...

INTRODUCTION: Prescription opioid (PO) misuse and related harms are high in Canada, and a major public health challenge. In Canada, 1.4 million individuals (4.3% of the total population) self-identify as Aboriginal, among whom substance use and related harms are elevated. While there are reports of PO use and associated problems among Aboriginal groups, no comprehensive data review currently exists. METHODS: A review of available data sources (ie journal publications, public reports and 'grey' literature) was conducted following principles of a scoping review...

OBJECTIVE: To ascertain demographic and clinical characteristics of maternal deaths from self-harm (accidental overdose or suicide) to identify opportunities for prevention. METHODS: We report a case series of pregnancy-associated deaths resulting from self-harm in the state of Colorado between 2004 and 2012. Self-harm deaths were identified from several sources, including death certificates. Birth and death certificates along with coroner, prenatal care, and delivery hospitalization records were abstracted...

STUDY QUESTION: To what extent is preconception use of pain-relieving medication associated with female fecundability? SUMMARY ANSWER: Women who used naproxen or opioids had slightly lower fecundability than women who did not use any pain-relieving medications; use of acetaminophen, aspirin and ibuprofen was not appreciably associated with fecundability. WHAT IS KNOWN ALREADY: Over-the-counter pain-relieving medications are commonly used by women of reproductive age in the USA...

Some important limitations must be taken into consideration for analgesic therapy during pregnancy. Paracetamol is the agent of choice for mild to moderate pain in any stage of pregnancy. Ibuprofen is the non-steroidal anti-inflammatory drug (NSAID) of choice; however, these substances are contraindicated after 28 weeks of gestation due to the increasing risk of premature closure of the ductus arteriosus and impairment of fetal kidney function. Even opioids can be used for severe pain but peripartum administration can lead to neonatal respiratory depression and adaptation disorders and long-term therapy up to the end of pregnancy can lead to neonatal withdrawal symptoms...

Licit and illicit drug use in pregnant women constitutes a long lasting and serious problem worldwide. Information on long-term effects of maternal drug use on the child is limited. Nationwide registers provide a great potential to study short and long-term consequences for children exposed to licit and illicit drugs during pregnancy. We discuss this potential, with a special emphasis on exposure to methamphetamine, heroin and prescription drugs used for opioid maintenance treatment (OMT). We also discuss the advantages of register data and of merging such data from different regions...

Background Propofol is a widely known, commonly used drug. Complications can occur with the use of this drug, including propofol-related infusion syndrome (PRIS). PRIS, in the obstetric population, has not been documented; however, we report a case of a patient who developed PRIS after an emergent cesarean delivery of a preterm infant. Case Study A 35-year-old multigravida woman presented complaining of leakage of fluid and decreased fetal movement. Her pregnancy was complicated by methadone maintenance therapy due to a history of opioid abuse...

Increase in the number of opioid dependent pregnant women delivering babies at risk for neonatal abstinence syndrome (NAS) prompted a General Accountability Office (GAO) report documenting deficits in research and provider knowledge about care of the maternal/fetal unit and the neonate. There are three general sources of dependence: untreated opioid use disorder (OUD), pain management, and medication assisted treatment with methadone or buprenorphine. A survey of methadone patients' experiences when telling a physician of their pregnancy and opioid dependence demonstrated physician confusion about proper care, frequent negative interactions with the mother, and failures to provide appropriate referral...

The United States is in the midst of an opiate epidemic, with abuse of prescription and illegal opioids increasing steadily over the past decade. While it is clear that there is a genetic component to opioid addiction, there is a significant portion of heritability that cannot be explained by genetics alone. The current study was designed to test the hypothesis that maternal exposure to opioids prior to pregnancy alters abuse liability in subsequent generations. Female adolescent Sprague Dawley rats were administered morphine at increasing doses (5-25 mg/kg, s...

Sex is one of several factors influencing pharmacological responses, but research on its effects on pharmacokinetics and pharmacodynamics, although emerging remarkably, remains poor and contains many methodological issues. In this review, the current state of knowledge about sex differences in pharmacokinetics and some hints to pharmacogenomics were evaluated. Moreover, considering that many pharmacological responses are monitored through biomarkers, the influence of sex on some biomarkers has been reported...

Estrogen action is necessary for evidencing the stimulatory action of mifepristone and naloxone on prolactin (PRL) secretion during late pregnancy. Our aim is to determine the mechanism mediating this facilitator action of estrogens. To investigate the hypothalamic mechanisms involved in estrogen actions in PRL secretion at the end of pregnancy, we measured the effect of pretreatment with the estrogen antagonist tamoxifen on the expression of tyrosine hydroxylase (TH), hormone receptors (ERα and β, PRs, PRLR(long)), and μ- and κ- opioid receptors (ORs) at mRNA (by semiquantitative RT-PCR) and protein (by western blot for TH, PRLR(long), ERα, PRs, μ- and ORs) levels in extracts of medial basal hypothalamus (MBH) and serum PRL, E2 and P4 levels (by RIA) in mifepristone- and naloxone-treated rats...

BACKGROUND: Buprenorphine is an FDA-approved maintenance therapy for opioid use disorders and is increasingly being used in pregnant women with opioid use disorders as an alternative to methadone. Dosing of buprenorphine in pregnant women is based on the regimen recommended for non-pregnant females and males. Limited data are available defining the pharmacokinetic (PK) properties of sublingual (SL) buprenorphine administered during pregnancy. OBJECTIVE: This study evaluated the impact of physiological changes associated with pregnancy on the PK of sublingual buprenorphine during and after pregnancy...

Birthweight is a marker for suboptimal fetal growth and development in utero. Offspring can be born large for gestational age (LGA), which is linked to maternal obesity or excessive gestational weight gain, as well as small for gestational age (SGA), arising from nutrient or calorie deficiency, placental dysfunction, or other maternal conditions (hypertension, infection). In humans, LGA and SGA babies are at an increased risk for certain neurodevelopmental disorders, including Attention Deficit/Hyperactivity Disorder, schizophrenia, and social and mood disorders...
