Abstract
Hypertension is a very prevalent condition associated with high mortality and morbidity, secondary to changes resulting in blood vessels and resultant end-organ damage. Haemodynamic changes, including an initial rise in cardiac output followed by an increase in total peripheral resistance, denote the early changes associated with borderline or stage 1 hypertension, especially in young men. Increased sodium reabsorption leading to kidney damage is another mechanism proposed as one of the initial triggers for essential hypertension. The underlying pathophysiological mechanisms include catecholamine-induced α1- and ß1-adrenoceptor stimulation, and renin-angiotensin-aldosterone system activation leading to endothelial dysfunction which is believed to lead to persistent blood pressure elevation.α1 blockers, α2 agonists, and ß blockers were among the first oral anti-hypertensives. They are no longer first-line therapy after outcome trials did not demonstrate any benefits over and above other agents, despite similar blood pressure reductions. Angiotensin-converting enzyme inhibitors (or angiotensin receptor blockers), calcium channel blockers, and thiazide-like diuretics are now considered the first line of therapy, although adrenoceptor agents still have a role as second- or third-line therapy. The chapter also highlights hypertension in specific medical conditions such as pregnancy, phaeochromocytoma, hyperthyroidism, portal hypertension, pulmonary arterial hypertension, and ocular hypertension, to provide an overview for clinicians and researchers interested in the role of adrenoceptors in the pathophysiology and management of hypertension.

Abstract
Introduction Hypertension during pregnancy is one of the most frequent causes of maternal and fetal morbimortality. Perinatal and maternal death and disability rates have decreased by 30%, but hypertension during pregnancy has increased by approximately 10% in the last 30 years. This research aimed to describe the pharmacological treatment and pregnancy outcomes of pregnancies with hypertension. Methods We carried out an observational cohort study from the Information System for the Development of Research in Primary Care (SIDIAP) database. Pregnancy episodes with hypertension (ICD-10 codes for hypertension, I10-I15 and O10-O16) were identified. Antihypertensives were classified according to the ATC WHO classification: β-blocking agents (BBs), calcium channel blockers (CCBs), agents acting on the renin-angiotensin system (RAS agents), diuretics, and antiadrenergic agents. Exposure was defined for hypertension in pregnancies with ≥2 prescriptions during the pregnancy episode. Descriptive statistics for diagnoses and treatments were calculated. Results In total, 4,839 pregnancies with hypertension diagnosis formed the study cohort. There were 1,944 (40.2%) pregnancies exposed to an antihypertensive medication. There were differences in mother's age, BMI, and alcohol intake between pregnancies exposed to antihypertensive medications and those not exposed. BBs were the most used (n = 1,160 pregnancy episodes; 59.7%), followed by RAS agents (n = 825, 42.4%), and CCBs were the least used (n = 347, 17.8%). Discussion Pregnancies involving hypertension were exposed to antihypertensive medications, mostly BBs. We conduct a study focused on RAS agent use during pregnancy and its outcomes in the offspring.

Prevention and control of non-communicable diseases in antenatal, intrapartum, and postnatal care: a systematic scoping review of clinical practice guidelines since 2011. BMC Med 2022; 20:305. [PMID: 36123668 PMCID: PMC9487084 DOI: 10.1186/s12916-022-02508-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2022] [Accepted: 08/01/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Non-communicable diseases (NCDs) are a leading cause of maternal mortality and morbidity worldwide. The World Health Organization is developing new recommendations focusing on the management of NCDs for pregnant, intrapartum, and postnatal women. Thus, to support the development of new guidelines and recommendations, we aimed to determine the availability, focus, and scope of recommendations of current guidelines for the management of NCDs during pregnancy, intrapartum, and postnatal period. METHODS PubMed, Global Index Medicus, TRIP, and Guideline International Network databases were searched on 31 May 2021, to identify any NCD-related guidelines published between 2011 and 2021 with no language or country restrictions. Websites of 165 professional organizations were also searched. Characteristics of included guidelines were analyzed, and recommendations were extracted from guidelines of five high-priority NCD conditions (diabetes, chronic hypertension, respiratory conditions, hemoglobinopathies and sickle cell disease, and mental and substance use disorders). RESULTS From 6026 citations and 165 websites, 405 guidelines were included of which 132 (33%) were pregnancy-specific and 285 (88%) were developed in high-income countries. Among pregnancy-specific guidelines, the most common conditions for which recommendations were provided were gestational diabetes, circulatory diseases, thyroid disorders, and hypertensive disorders of pregnancy. For the five high-priority conditions, 47 guidelines were identified which provided 1834 recommendations, largely focused on antenatal care interventions (62%) such as early detection, screening tools, pharmacological treatment, and lifestyle education. Postnatal recommendations largely covered postnatal clinical assessments, lifestyle education, and breastfeeding. Health system recommendations largely covered multidisciplinary care teams and strengthening referral pathways. CONCLUSIONS This study provides a robust assessment of currently available guidelines and mapping of recommendations on NCD management within maternal health services, which will inform the scope of the World Health Organization's future guideline development activities. This study identified a need to develop guidelines that consider NCDs holistically, with an integrated approach to antenatal, intrapartum, and postnatal care, and that are relevant for resource-limited contexts. Any such guidelines should consider what interventions are most essential to improving outcomes for women with NCDs and their newborns, and how variations in quality of NCD-related care can be addressed.

Pharmacokinetics of the most commonly used antihypertensive drugs throughout pregnancy methyldopa, labetalol, and nifedipine: a systematic review. Eur J Clin Pharmacol 2022; 78:1763-1776. [PMID: 36104450 PMCID: PMC9474278 DOI: 10.1007/s00228-022-03382-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2022] [Accepted: 09/03/2022] [Indexed: 01/09/2023]
Abstract
Abstract
Purpose
Antihypertensive drugs are among the most prescribed drugs during pregnancy. Methyldopa, labetalol, and nifedipine have been perceived safe to use during pregnancy and are therefore recommended in international guidelines for treatment of hypertension. In this review, we provide a complete overview of what is known on the pharmacokinetics (PK) of the antihypertensive drugs methyldopa, labetalol, and nifedipine throughout pregnancy.
Methods
A systematic search was performed to retrieve studies on the PK of methyldopa, labetalol, and nifedipine used throughout pregnancy. The search was restricted to English and original studies. The systematic search was conducted on July 27, 2021, in Embase, Medline Ovid, Web of Science, Cochrane Library, and Google Scholar. Keywords were methyldopa, labetalol, nifedipine, pharmacokinetics, pregnancy, and placenta.
Results
A total of 1459 unique references were identified of which title and abstract were screened. Based on this screening, 67 full-text papers were assessed, to retain 30 PK studies of which 2 described methyldopa, 12 labetalol, and 16 nifedipine. No fetal accumulation is found for any of the antihypertensive drugs studied.
Conclusion
We conclude that despite decades of prescribing methyldopa, labetalol, and nifedipine throughout pregnancy, descriptions of their PK during pregnancy are hampered by a large heterogeneity in the low number of available studies. Aiming for evidence-based and personalized dosing of antihypertensive medication in the future, further studies on the relationship of both PK and pharmacodynamics (including the optimal blood pressure targeting) during pregnancy and pregnancy-related pathology are urgently needed to prevent undertreatment, overtreatment, and side effects.

Abstract
BACKGROUND Several studies have reported an association between perinatal complications and the severity of the hypertensive disease. The increasing number of pregnancies complicated by hypertension and the small assurance about the perinatal effects of hypertensive drug use during pregnancy involves the need of studying the better management of hypertensive mothers. OBJECTIVE To evaluate the association between maternal use of antihypertensive drugs and maternal and neonatal outcomes in women with chronic hypertension. STUDY DESIGN We conducted a population-based study including all deliveries of hypertensive women that occurred between 2007-2017 in the Lombardy region, Italy. We evaluated the risk of several maternal and neonatal outcomes among women who filled antihypertensive prescriptions within the 20th week of gestation. Propensity score stratification was used to account for key potential confounders. RESULTS Out of 5,553 pregnancies, 2,138 were exposed to antihypertensive treatment. With respect to no-users, users of antihypertensive drugs showed an increased risk of preeclampsia (RR:1.68, 95%CI:1.42-1.99), low birth weight (1.30,1.14-1.48), and preterm birth (1.25,1.11-1.42). These results were consistent in a range of sensitivity and subgroup analyses. CONCLUSION Early exposure to antihypertensive drugs in the first 20 weeks of gestation was associated with an increased risk of preeclampsia, low birth weight, and preterm birth.

Abstract
Liddle syndrome is an inherited form of arterial hypertension with autosomal dominant pattern of inheritance. It is caused by activating mutation of genes coding of the epithelial sodium channel in distal nephron. Mutation leads to excessive reabsorbtion of sodium ions and volume expansion resulting in arterial hypertension. Antoher typical laboratory findings are hypokalaemia, low levels of serum aldosteron and metabolic alkalosis. Phenotypic variability makes it difficult to identify patients with Liddle syndrome, often resulting in misdiagnosis and severe complications at early age. Genetic studies should be done to confirm the diagnosis. Therapy of Liddle syndrome is based on administration of epithelial sodium channel blocker amilorid.

Abstract
INTRODUCTION Hypertensive disorders of pregnancy (HDP) are rising in prevalence, and increase risk of adverse maternal and fetal outcomes. Physiologic changes occur during pregnancy that alter drug pharmacokinetics. However, antihypertensive drugs lack pregnancy-specific dosing recommendations due to critical knowledge gaps surrounding the extent of gestational changes in antihypertensive drug pharmacokinetics and underlying mechanisms. AREAS COVERED This review (1) summarizes currently recommended medications and dosing strategies for non-emergent HDP treatment, (2) reviews and synthesizes existing literature identified via a comprehensive Pubmed search evaluating gestational changes in the maternal pharmacokinetics of commonly prescribed HDP drugs (notably labetalol and nifedipine), and (3) offers insight into the metabolism and clearance mechanisms underlying altered HDP drug pharmacokinetics during pregnancy. Remaining knowledge gaps and future research directions are summarized. EXPERT OPINION A series of small pharmacokinetic studies illustrate higher oral clearance of labetalol and nifedipine during pregnancy. Pharmacokinetic modeling and preclinical studies suggest these effects are likely due to pregnancy-associated increases in hepatic UGT1A1- and CYP3A4-mediated first-pass metabolism and lower bioavailability. Accordingly, higher and/or more frequent doses may be needed to lower blood pressure during pregnancy. Future research is needed to address various evidence gaps and inform the development of more precise antihypertensive drug dosing strategies.

Abstract
AIMS Beta-blockers are commonly used to treat hypertension that arises during pregnancy. However, reproductive safety concerns have been expressed. Here, we investigated whether the use of β-blockers during early pregnancy increased the risk of congenital malformations. METHODS A systematic literature search was performed in PubMed, Embase and Cochrane Library to identify relevant studies published from database inception until February 2020. Observational studies evaluating associations between maternal β-blocker use and congenital malformations were included in this meta-analysis. Two reviewers independently extracted data and assessed study quality. Meta-analysis of outcomes was performed and a summary odds ratio (OR) was calculated with consideration of heterogeneity. RESULTS Twenty observational studies were identified. Beta-blocker use during early pregnancy was not associated with an increased risk of congenital malformations (OR = 1.01, 95% confidence interval [CI] = 0.93-1.09). Subgroup analysis of organ-specific malformations revealed that β-blocker use was associated with an increased risk of heart malformations (OR = 1.29, 95% CI = 1.02-1.63) and an increased risk of cleft lip or palate (OR = 1.5, 95% CI = 1.18-1.91); however, these associations (OR = 1.11, 95% CI = 0.94-1.32 for heart malformations; OR = 1.34, 95% CI = 0.98-1.85 for cleft lip or palate) disappeared when the adjusted data were pooled. Beta-blocker use was not associated with increased risks of central nervous system malformations, neural tube defects or hypospadias. CONCLUSION Exposure to β-blockers during early pregnancy does not appear to be associated with congenital malformations or heart malformations in offspring. Other organ-specific congenital malformations should be evaluated in further studies.

Abstract
OBJECTIVES Hypertensive disorder is a common medical condition in pregnancy. However, the recommendations for antihypertensive use during pregnancy are based on limited evidence and various factors affect their selection in clinical practice. We aim to assess the prevalence of antihypertensive use and describe which medications are being used in pregnancy. STUDY DESIGN We conducted a cohort study of all pregnancies resulted in a live birth between 2013 and 2017, by using the Health Insurance Review and Assessment (HIRA) database of South Korea. Based on duration of drug supplied, we examined antihypertensive use during the pre-pregnancy, pregnancy, and postpartum periods. We described the patterns of discontinuing, continuing, switching, and initiating antihypertensive medications during pregnancy. RESULTS We included 2,030,821 pregnancies, of whom 0.9%, 3.1%, and 1.8% were dispensed antihypertensives in the pre-pregnancy, pregnancy, and postpartum periods, respectively. The most frequent medications used were dihydropyridines (40.7%), beta-blockers (38.4%) and Angiotensin II Receptor Blockers (16.8%) in the first trimester, and dihydropyridines (89.7%) and vasodilators (11.5%) in the third trimester. Among women exposed to antihypertensives during pregnancy, this was the first use in 86.3% of women. Among women receiving antihypertensives before pregnancy, 77.9% discontinued treatment during pregnancy, whereas 13.2% continued to take their pre-pregnancy medications. CONCLUSION The prevalence of antihypertensive use during pregnancy was 3.1% in South Korea. Overall, while dihydropyridines were predominant, other types of antihypertensives were also commonly dispensed during pregnancy. It suggests a need to investigate the effect of exposure to various types of antihypertensives of which safety remains unclear during pregnancy.

Abstract
This study evaluates how atenolol affects dental mineralization in offspring of female spontaneously hypertensive rats (fSHR) and normotensive Wistar rats (fW). fSHR and fW were treated with atenolol (100 mg/Kg/day, orally) during pregnancy and lactation. Non-treated fSHR and fW were the control groups. Enamel and dentin hardness were analyzed (Knoop, 15 g load, 10s) in mandibular incisor teeth (IT) and molar teeth (MT) obtained from the male offspring of atenolol-treated and non-treated fWistar and fSHR. Data were analyzed by ANOVA, followed by Tukey post hoc test (p < 0.05). Atenolol reduced the arterial blood pressure (SBP) in fSHR, but it did not change the SBP in fW. The offspring of non-treated fSHR had lower enamel (IT and MT) and dentin (IT) hardness than the offspring of non-treated fW (p < 0.05). Atenolol increased enamel and dentin hardness in the IT obtained from the offspring of fSHR and fW (p<0.05), but the offspring of fSHR presented higher values (p < 0.05). Atenolol did not alter enamel width in the IT obtained from any of the groups, but it increased enamel and dentin hardness in the IT obtained from the offspring of fSHR and fW. Atenolol affected the IT obtained from the offspring of fSHR. Atenolol increased only enamel hardness in the MT obtained from the offspring of fW. In conclusion, maternal hypertension reduces tooth hard tissues, and treatment with atenolol increases tooth hardness in male offspring of hypertensive and normotensive female rats.

Abstract
INTRODUCTION Hypertensive disorders of pregnancy (HDP) represent a major cause of maternal, fetal and neonatal morbidity and mortality and identifies women at risk for cardiovascular and other chronic diseases later in life. When antihypertensive drugs are used during pregnancy, their benefit and harm to both mother and fetus should be evaluated. AREAS COVERED This review summarizes the pharmacological characteristics of the recommended antihypertensive drugs and their impact on mother and fetus when administered during pregnancy and/or post-partum. Drugs were identified using MEDLINE and the main international Guidelines for the management of HDP. EXPERT OPINION Although there is a consensus that severe hypertension should be treated, treatment of mild hypertension without end-organ damage (140-159/90-109 mmHg) remains controversial and there is no agreement on when to initiate therapy, blood pressure targets or recommended drugs in the absence of robust evidence for the superiority of one drug over others. Furthermore, the long-term outcomes of in-utero antihypertensive exposure remain uncertain. Therefore, evidence-based data regarding the treatment of HDP is lacking and well designed randomized clinical trials are needed to resolve all these controversial issues related to the management of HDP.

Abstract
Adequate maternal vascular adaptations and blood supply to the uterus and placenta are crucial for optimal oxygen and nutrient transport to growing fetuses of eutherian mammals, including humans. Multiple factors contribute to hemodynamics and structuring of placental vasculature essential for term pregnancy with minimal complications. In women, failure to achieve or sustain favorable pregnancy progression is, not surprisingly, associated with high incidence of antenatal complications, including preeclampsia, a hypertensive disorder of pregnancy. While the pathogenesis of preeclampsia in women remains unknown, a role for androgens is emerging. The relationship between androgens and maternal cardiovascular and placental function deserves particular consideration because testosterone levels in the circulation of preeclamptic women are elevated approximately two- to three-fold and are positively correlated with vascular dysfunction. Preeclampsia is also associated with elevated placental androgen receptor (AR) gene expression. Studies in animal models mimicking the pattern and level of increase of adult female testosterone levels to those found in preeclamptic pregnancies, replicate key features of preeclampsia, including gestational hypertension, endothelial dysfunction, exaggerated vasoconstriction to angiotensin II, reduced spiral artery remodeling, placental hypoxia, decreased nutrient transport and fetal growth restriction. Taken together, these data strongly implicate AR-mediated testosterone action as an important pathway contributing to clinical manifestation of preeclampsia. This review critically addresses this hypothesis, taking into consideration both clinical and preclinical data.

Abstract
OBJECTIVE Previous research reported greater risk of adverse perinatal outcomes associated with first trimester exposure to angiotensin converting enzyme inhibitors (ACEIs) in comparison to unexposed pregnancies among non-hypertensive women. We examined the relationship between first trimester exposure to ACEIs and angiotensin receptor blockers (ARBs), and maternal and perinatal outcomes, whilst controlling for the underlying hypertension. STUDY DESIGN We performed a population-based cohort study among 130,061 pregnancies resulting in birth in NSW, Australia between 2005 and 2012. Birth data were linked to hospital discharge and pharmaceutical dispensing records. After restricting to women with chronic hypertension, 67 and 73 pregnancies exposed to ACEIs and ARBs respectively during the first trimester were compared with 316 pregnancies exposed to methyldopa. STUDY OUTCOMES Preterm delivery, caesarean section, low birth weight, small for gestational age and Apgar score <7. RESULTS Compared to pregnancies exposed to methyldopa, the adjusted odds ratio (aOR) for ACEI exposure was 0.5 (95% CI: 0.2-1.1) for preterm delivery, 1.6 (0.8-3.1) for caesarean section, 0.6 (0.2-1.3) for LBW and 0.8 (0.4-1.9) for SGA. The corresponding aORs and confidence intervals for ARB exposure were 0.7 (0.3-1.5), 1.2 (0.6-2.6), 1.3 (0.7-2.6), and 1.2 (0.6-2.4). CONCLUSION No association between early pregnancy exposure to ACEIs and ARBs and perinatal outcomes was observed, however, the possibility of an association cannot be ruled out due to limited power. Nonetheless, this study suggests that the magnitude of risk is smaller than that reported previously.

Abstract
The expression of inflammatory factors, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and high-sensitivity C-reactive protein (hs-CRP), in patients with pregnancy-induced hypertension (PIH) was investigated, to analyze correlation of expression levels of these factors in patients with unfavorable fetal outcome. A total of 100 patients diagnosed with PIH treated in Jining First People's Hospital (Jining, China) from January 2012 to October 2017 were selected as the experimental group, while 100 normal pregnant women during the same period were selected as the control group. Results showed that the levels of IL-6, TNF-α and hs-CRP in patients with PIH were significantly higher than those in normal pregnant women (p<0.01). There were significant differences in levels of IL-6, TNF-α and hs-CRP among patients with hypertension in different degrees. The expression levels of IL-6, TNF-α and hs-CRP in PIH patients with favorable pregnancy outcome were lower than those in patients with unfavorable pregnancy outcome (p<0.05). Moreover, the expression levels of IL-6, TNF-α and hs-CRP had a linearly positive correlation with systolic blood pressure in PIH patients. Age, height and weight had no significant correlation with unfavorable pregnancy outcome of PIH patients (p>0.05). Finally, inflammatory factors (TNF-α, IL-6 and hs-CRP) and blood pressure were obviously and positively correlated with unfavorable pregnancy outcome of PIH patients (p<0.05). In conclusion, the expression of inflammatory factors (TNF-α, IL-6 and hs-CRP) in PIH patients are positively correlated with the systolic blood pressure and unfavorable fetal outcome of patients, which can be used as indexes of prognosis evaluation of PIH patients.

Abstract
PURPOSE OF REVIEW Preeclampsia (PE) is a disorder of pregnancy typically characterized by new-onset hypertension and proteinuria after gestational week 20. Although preeclampsia is one of the leading causes of maternal and perinatal morbidity and death worldwide, the mechanisms of the pathogenesis of the disorder remain unclear and treatment options are limited. Placental ischemic events and the release of placental factors appear to play a critical role in the pathophysiology. These factors contribute to a generalized systemic vascular endothelial dysfunction and result in increased systemic vascular resistance and hypertension. RECENT FINDINGS There is increasing evidence to suggest that endothelin-1 (ET-1) in the maternal vascular endothelium is a critical final common pathway, whereby placental ischemic factors cause cardiovascular and renal dysfunction in the mother. Multiple studies report increased levels of ET-1 in PE. A number of experimental models of PE are also associated with elevated tissue levels of prepro-ET-1 mRNA. Moreover, experimental models of PE (placental ischemia, sFlt-1 excess, TNF-α excess, and AT1-AA infusion) have proven to be responsive to ET type A receptor antagonism. Recent studies also suggest that abnormalities in ET type B receptor signaling may also play a role in PE. Although numerous studies highlight the importance of the ET system in the pathogenesis of PE, further work is needed to determine whether ET receptor antagonists could provide an effective therapy for the management of this disease.

Abstract
BACKGROUND Ongoing discussion about the safety of renin-angiotensin inhibitors in the first trimester and limited data on pregnancy outcomes after exposure to angiotensin AT1 receptor blockers (ARBs). METHODS Observational cohort study compares outcomes of 215 prospectively ascertained pregnancies with first trimester exposure to ARBs with 642 non-hypertensive pregnancies. RESULTS The rate of major birth defects in the ARB cohort (9/168, 5.4%) was higher than in the comparison group (17/570, 3%), but not significantly increased (ORadj 1.9, 95% CI 0.7-4.9). There was no distinct pattern of anomalies among infants with birth defects. The risk of spontaneous abortions was not increased (HRadj 0.9, 95% CI 0.5-1.6), although the cumulative incidence was in the upper normal range (0.22, 95% CI 0.15-0.32). Higher rates of prematurity (ORadj 3.0; 95% CI 1.7-5.1) and a reduced birth weight after adjustment for sex and gestational age were observed. There was no evidence for an increased risk for major birth defects, spontaneous abortions, or preterm birth in a sensitivity analysis comparing ARB exposed hypertensive women to hypertensive women without ARB exposure during the first trimester. CONCLUSION Our study supports the hypothesis that ARBs are not major teratogens. Patients inadvertently exposed to ARBs during the early pregnancy may be reassured. Nevertheless, women planning pregnancy should avoid ARBs. In selected cases, ARBs might be continued under careful monitoring of menstrual cycle and discontinued as soon as pregnancy is recognized.

Abstract
Published experience on first trimester exposure to methyldopa is still limited, although it is recommended as first-line treatment for hypertensive disorders in pregnancy in most countries. The primary aim of this prospective observational cohort study was to analyze the rate of major birth defects and spontaneous abortions in women with methyldopa therapy for chronic hypertension. Outcomes of 261 pregnancies with first trimester exposure to methyldopa and 526 comparison pregnancies without chronic hypertension reported to the German Embryotox pharmacovigilance institute were evaluated. The rate of major birth defects in the exposed cohort was not significantly increased compared with the comparison cohort (3.7% versus 2.5%; adjusted odds ratio, 1.24; 95% confidence interval, 0.4-4.0). There was a tendency toward a higher rate of spontaneous abortions in exposed women. The risk of preterm birth was significantly higher, and adjusted birth weight scores were significantly lower in the methyldopa group. Head circumferences were significantly reduced in exposed boys only. There was neither evidence for an increased risk for birth defects or increase in early pregnancy loss nor evidence for growth restriction or a reduced head circumference in a sensitivity analysis comparing monotherapies with methyldopa to metoprolol. However, the significantly increased risk of preterm birth in methyldopa-treated pregnancies was confirmed. In conclusion, our study does not indicate a teratogenic risk of methyldopa. Further studies are needed to confirm its safety in the first trimester and clarify the influence of hypertension and methyldopa on preterm birth and intrauterine growth.

Abstract
Clinicians make frequent treatment decisions regarding acute blood pressure reduction for the critically ill. Key to the decision making process is a balance between reducing arterial wall stress and maintaining perfusion to vital organs. In this article, we review the physiological considerations underlying acute blood pressure management, including the concept of cerebral autoregulation and its adaptations to chronic hypertension. We then discuss available pharmacological interventions suited for reducing blood pressure acutely. We also discuss specific blood pressure targets in common critical illnesses and consider future directions in this therapeutic area.

Abstract
The success of cardiac surgery over the past 50 years has increased numbers and median age of survivors with congenital heart disease (CHD). Adults now represent two-thirds of patients with CHD; in the USA alone the number is estimated to exceed 1 million. In this population, many affected women reach reproductive age and wish to have children. While in many CHD patients pregnancy can be accomplished successfully, some special situations with complex anatomy, iatrogenic or residual pathology are associated with an increased risk of severe maternal and fetal complications. Pre-conception counselling allows women to come to truly informed choices. Risk stratification tools can also help high-risk women to eventually renounce to pregnancy and to adopt safe contraception options. Once pregnant, women identified as intermediate or high risk should receive multidisciplinary care involving a cardiologist, an obstetrician and an anesthesiologist with specific expertise in managing this peculiar medical challenge. This document is intended to provide cardiologists working in hospitals where an Obstetrics and Gynecology Department is available with a streamlined and practical tool, useful for them to select the best management strategies to deal with a woman affected by CHD who desires to plan pregnancy or is already pregnant.

Abstract
Background Because pregnant women are often excluded from clinical trials, there is still very limited information about the risk and safety of prescription drugs during pregnancy. Objective We aimed to determine the prevalence of Adverse Drug Reactions (ADRs) in high-risk pregnant women after hospital admission. A prospective study was carried out in a teaching maternity hospital in Brazil during six months. Causality of ADRs was assessed through the Naranjo Algorithm and Korean Algorithm for ADR Causality Assessment. Severity of ADRs was assessed using Hartwig’s Severity Assessment Scale. Results The prevalence of ADRs among the 294 inpatients studied was 8.8%. The mean age was 27.14 (±7.5) y.o. Patient's age was related to the presence of ADRs, while the manifestation of these events was not associated with any adverse pregnancy outcome. 75.9% of the ADRs reported in the study were of mild severity and 24.1% were of moderate severity. No ADR was caused by drug-drug interaction; however, a significant increase in blood pressure was observed in all patients using concurrent methyldopa and ferrous sulfate. Conclusion Overall, ADRs were not common events among high-risk pregnant women and no adverse pregnancy outcomes following these events were observed.

Abstract
AIMS Diabetes mellitus can inhibit cytochrome P450 3A4, an enzyme responsible for the metabolism of nifedipine, used for the treatment of hypertension in pregnant women. We aimed to assess the effect of type 2 diabetes mellitus (T2DM) on the pharmacokinetics, placental transfer and distribution of nifedipine in amniotic fluid in hypertensive pregnant women. METHODS The study was conducted in 12 hypertensive pregnant women [control group (CG)] and 10 hypertensive pregnant women with T2DM taking slow-release nifedipine (20 mg, 12/12 h). On the 34th week of gestation, serial blood samples were collected (0-12 h) after administration of the medication. At delivery, samples of maternal and fetal blood and amniotic fluid were collected for determination of nifedipine distribution in these compartments. RESULTS The median pharmacokinetic parameters of CG were: peak plasma concentration (Cmax ) 26.41 ng ml-1 , time to reach Cmax (tmax ) 1.79 h, area under the plasma concentration vs. time curve from 0-12 h (AUC0-12 ) 235.99 ng.h ml-1 , half-life (t½) 4.34 h, volume of distribution divided by bioavailability (Vd/F) 560.96 l, and ClT /F 84.77 l h-1 . The parameters for T2DM group were: Cmax 23.52 ng ml-1 , tmax 1.48 h, AUC0-12 202.23 ng.h ml-1 , t½ 5.00 h, Vd/F 609.40 l, and apparent total clearance (ClT /F) 98.94 l h-1 . The ratios of plasma concentrations of nifedipine in the umbilical vein, intervillous space and amniotic fluid to those in the maternal vein for CG and T2DM were 0.53 and 0.44, 0.78 and 0.87, respectively, with an amniotic fluid/maternal plasma ratio of 0.05 for both groups. The ratios of plasma concentrations in the umbilical artery to those in the umbilical vein were 0.82 for CG and 0.88 for T2DM. CONCLUSIONS There was no influence of T2DM on the pharmacokinetics or placental transfer of nifedipine in hypertensive women with controlled diabetes.

Abstract
Chronic kidney disease (CKD) is increasingly encountered in pregnancy, and hypertension is frequently concomitant. In pregnancy, the prevalence of CKD is estimated to be about 3%, while the prevalence of chronic hypertension is about 5-8%. The prevalence of hypertension and CKD in pregnancy is unknown. Both are independently related to adverse pregnancy outcomes, and the clinical picture merges with pregnancy-induced hypertension and preeclampsia. Precise risk quantification is not available, but risks linked to CKD stage, hypertension, and proteinuria are probably multiplicative, each at least doubling the rates of preterm and early preterm delivery, small for gestational age babies, and related outcomes. Differential diagnosis (based upon utero-placental flows, fetal growth, and supported by serum biomarkers) is important for clinical management. In the absence of guidelines for hypertension in CKD pregnancies, the ideal blood pressure goal has not been established; we support a tailored approach, depending on compliance, baseline control, and CKD stages, with strict blood pressure monitoring. The choice of antihypertensive drugs and the use of diuretics and of erythropoiesis-stimulating agents (ESAs) are still open questions which only future studies may clarify.

Abstract
I report a case of hypotension and bradycardia before spinal anesthesia in a pregnant woman with mild to moderate hypertension treated with nifedipine and methyldopa, scheduled for an elective cesarean delivery. She had the history of neurally-mediated syncopes. Two main factors (increased vagal tone and adverse effects of antihypertensive drugs) could explain the hypotension and bradycardia before spinal anesthesia. Monitoring allowed recognizing the problem and corrected it. Thus, it was avoided a disaster in anesthesia, as hemodynamic changes after spinal anesthesia, they would have joined to previous hypotension and bradycardia, which would have caused even a cardiac arrest.

Abstract
Hypertension affects one-third of all females in the United States, with the prevalence increasing over a female's lifespan. The approach to treating females with hypertension varies depending on a female's age, race, comorbidities, and whether she is of child-bearing age or pregnant. It is important to factor in the safety and effectiveness of antihypertensive medications across these populations of females. Blood pressure target goals are the same in females as in males regardless of comorbidities or stage of life, with the exception of those females who are pregnant. Recommendations for antihypertensive medication do not differ between females and males based on disease state or stage of life, with the exception of females who are pregnant, breastfeeding, or of child-bearing age. Multiple guidelines recommend avoiding renin-angiotensin system blockers during pregnancy and suggest balancing the risk versus benefit in females of child-bearing age. Further, multiple guidelines provide race-based therapy recommendations for the use of calcium channel blockers and thiazide diuretics in black versus nonblack patients, irrespective of sex. Future research is needed to evaluate whether there are sex differences relative to blood pressure and cardiovascular event-lowering relative to specific antihypertensive medications with a focus on pharmacogenomic differences.

Abstract
Hypertension is the most commonly encountered medical condition in pregnancy, contributing significantly to maternal and perinatal morbidity and mortality. Mild to moderate hypertension in pregnancy is defined as systolic blood pressure of 140-159 mmHg or diastolic blood pressure of 90-109 mmHg (7-9% of pregnancies). When treating hypertension in pregnancy, not only do physiologic changes of pregnancy have an effect on the pharmacokinetics and pharmacodynamics of the drugs used, but the pathophysiology of hypertensive disorders of pregnancy also have an effect. To date, evidence is lacking on the pharmacokinetics and pharmacodynamics of commonly used antihypertensive drugs, which often times leads to suboptimal treatment of hypertensive pregnant women. When considering which agents to use for treatment of mild to moderate hypertension, specifically in gestational and chronic hypertension, oral labetalol and nifedipine are valid options. An overview of the profile for use, safety, and current pharmacokinetic data for each agent is presented here.

Abstract
Background: Published clinical practice guidelines have addressed antihypertensive therapy and sexual dysfunction (SD) in many different ways. Objective: In this systematic review, we evaluated guidelines that address antihypertensive drug-associated SD, guideline recommendations, and recent guideline trends. Methods: Thirty sets of guidelines for hypertension management in adults that had been published in the English language since 2000 were reviewed. The primary outcome measure was antihypertensive-associated SD potential, which was independently evaluated using specific questions by 2 authors in a nonblinded standardized manner. Results: Sexual dysfunctions associated with thiazide-class diuretics, β-blockers, and centrally acting sympathoplegics were addressed by half of the guidelines reviewed. There is no clarity on β-blockers and thiazide-class diuretics because one-third of the guidelines are vague about individual β-blockers and diuretics, and there is no statement on third-generation β-blockers and thiazide-like diuretics that can improve erectile function. The revised guidelines never use terms such as loss of libido, ejaculatory dysfunction, lack of orgasm, and priapism. Summary versions of guidelines are inadequate to reflect the key interpretation of the primary guidelines on SD associated with antihypertensives, even in the major guidelines that were updated recently. Therapeutic issues such as exploring SD in clinical history, assessing SD prior to and during treatment with antihypertensives, substituting the offending agents with alternatives that possess a better safety profile, intervening with phosphodiesterase-5 inhibitors, and avoiding the concomitant use of nitrovasodilators are superficially addressed by most guidelines, with the exception of 2013 European Society of Hypertension/European Society of Cardiology and Seventh Joint National Committee recommendations. Conclusion: Future guideline revisions, including both full and summary reports, should provide a balanced perspective on antihypertensive-related SD issues to improve the impact of hypertension treatment guidelines on patient care and quality of life.

Abstract
The prevalence of hypertensive disorders in pregnancy is increasing. The etiology and pathophysiology of hypertensive disorders in pregnancy remain poorly understood. Hypertensive disorders are a major cause of maternal and perinatal morbidity and mortality. Treatment of hypertension decreases the incidence of severe hypertension, but it does not impact rates of preeclampsia or other pregnancy complications. Several antihypertensive medications are commonly used in pregnancy, although there is a lack of randomized controlled trials. Severe hypertension should be treated immediately to prevent maternal end-organ damage. Appropriate antepartum, intrapartum, and postpartum management is important in caring for patients with hypertensive disorders.

Abstract
Maternal hypertension is common during pregnancy, and multiple studies have reported on an association between maternal hypertension and congenital heart defects (CHDs) in offspring; however, there is variability in the quality of these studies. A systematic review and meta-analysis was conducted on the associations between untreated and treated maternal hypertension and the risk of CHDs, evaluating CHDs overall as well as specific CHD subtypes. A systematic search of peer-reviewed articles published before August 2013 identified 16 studies evaluating the associations between untreated and treated maternal hypertension and CHDs. Summary relative risk (RR) estimates were calculated using fixed-effects models and random-effects models. Significant associations were observed between maternal hypertension and overall CHDs, for both treated [RR 2.0; 95 % confidence interval (CI) 1.5, 2.7] and untreated (RR 1.4; 95 % CI 1.2, 1.7) hypertension, as well as for overall hypertension regardless of treatment status (RR 1.8; 95 % CI 1.5, 2.2). The magnitude of effect was similar for the majority of CHD subtypes evaluated. The effects were also similar among women with hypertension who used one of multiple specific hypertension medications. There was no evidence of publication bias, and our results were robust to several factors considered in sensitivity analyses (e.g., source of exposure data, adjustment for potential confounders, and study design). Maternal hypertension was associated with CHDs. By understanding the specific mechanisms involved, appropriate strategies may be developed to reduce this risk, in order to prevent CHDs.

Abstract
Despite good evidence regarding the benefits of managing hypertension in elderly populations, the extent to which this evidence has been incorporated into national and international clinical hypertension treatment guidelines is unknown. A systematic review was conducted to identify recommendations in current national and international hypertension treatment guidelines with a focus on specific targets and treatment recommendations for older persons with uncomplicated hypertension. Guidelines for the management of hypertension published or updated over a 5-year period (2009-2014) were identified by searching Medline, Google, and Google Scholar. Thirteen guidelines that met the predefined inclusion criteria were included in the review. Among these guidelines was considerable variation regarding who is considered an older person. However, there was general consensus regarding blood pressure targets. While current hypertension guidelines do include recommendations regarding management of uncomplicated hypertension in older populations, the depth and breadth of these recommendations vary considerably between guidelines and may limit the usefulness of such treatment guidelines to clinicians.

Abstract
BACKGROUND Pregnancy during dialysis is increasingly being reported and represents a debated point in Nephrology. The small number of cases available in the literature makes evidence-based counselling difficult, also given the cultural sensitivity of this issue. Hence, the need for position statements to highlight the state of the art and propose the unresolved issues for general discussion. METHODS A systematic analysis of the literature (MESH, Emtree and free terms on pregnancy and dialysis) was conducted and expert opinions examined (Study Group on Kidney and Pregnancy; experts involved in the management of pregnancy in dialysis in Italy 2000-2013). Questions regarded: timing of dialysis start in pregnancy; mode of treatment, i.e. peritoneal dialysis (PD) versus haemodialysis (HD); treatment schedules (for both modes); obstetric surveillance; main support therapies (anaemia, calcium-phosphate parathormone; acidosis); counselling tips. MAIN RESULTS Timing of dialysis start is not clear, considering also the different support therapies; successful pregnancy is possible in both PD and HD; high efficiency and strict integration with residual kidney function are pivotal in both treatments, the blood urea nitrogen test being perhaps a useful marker in this context. To date, long-hour HD has provided the best results. Strict, personalized obstetric surveillance is warranted; therapies should be aimed at avoiding vitamin B12, folate and iron deficits, and at correcting anaemia; vitamin D and calcium administration is safe and recommended. Women on dialysis should be advised that pregnancy is possible, albeit rare, with both types of dialysis treatment, and that a success rate of over 75% may be achieved. High dialysis efficiency and frequent controls are needed to optimize outcomes.

Abstract
This review is intended to help clinicians design drug regimens for special populations of critically ill patients with extremes of body size, habitus and composition that make drug choice or dosing particularly challenging due to the lack of high-level evidence on which to make well-informed clinical decisions. The data sources included a literature search of MEDLINE and EMBASE with reviews of reference lists of retrieved articles. Abstracts of original research investigations and review papers were reviewed for their relevance to drug choice or dosing in the following special critically ill populations: patients with more severe forms of bodyweight or height, patients with amputations or missing limbs, pregnant patients, and patients undergoing extracorporeal membrane oxygenation or plasma exchange. Relevant papers were retrieved and evaluated, and their associated reference lists were reviewed for citations that may have been missed through the electronic search strategy. Relevant original research investigations and review papers that could be used to formulate general principles for drug choice or dosing in special populations of critically ill patients were extracted. Randomized studies with clinically relevant endpoints were not available for performing quantitative analyses. Critically ill patients with changes in body size, habitus and composition require special consideration when designing medication regimens, but there is a paucity of literature on which to make drug-specific, high-level evidence-based recommendations. Based on the evidence that is available, general recommendations are provided for drug choice or dosing in special critically ill populations.

Abstract
ABSTRACT Cardiovascular disease is the most encountered cause of maternal death during pregnancy in the western world and an increase in maternal mortality due to cardiac causes has been observed. More women with congenital or acquired heart disease have the desire to become pregnant. Pregnancy is known to impose a major hemodynamic burden and also has impacts on the coagulation system. The risk of developing complications is clearly increased as compared with the normal population. For optimal management, it is crucial to have information on the effects of cardiac medications on the fetus. The focus of this article is to discuss the management of cardiac disease in pregnancy, as well as the known safety of cardiac medications for the mother and/or fetus.

BACKGROUND: Pre-eclampsia is one of the most important causes of a rare cliniconeuroradiological entity called posterior reversible encephalopathy syndrome. The syndrome is characterized by headacke, visual disturbances, seizures, altered mental status and radiological findings of edema in the white matter of the brain areas perfused by the posterior brain circulation.CASE REPORT: Here we present a patient with sudden bilateral visual loss and deafness in early postnatal period without any other neurological deficits, but with affiliated ophthalmological pathology. The correct diagnosis was made 3 days after the Cesarean section.The patient was diagnosed with posterior reversible encephalopathy syndrome and bilateral choroidal detachment.CONCLUSION: Vascular changes in posterior reversible encephalopathy syndrome can cause visual disturbances not only by brain edema, but combined brain and ocular pathology.

Abstract
Liddle's syndrome (LS) is a rare heritable form of hypertension that often affects young patients. It is caused by gain-of-function mutations of the kidney epithelial sodium channel (ENaC) and it is classically associated with hypokalemia and suppression of renin and aldosterone. LS is characterized by responsiveness to ENaC inhibitors but not to mineralocorticoid receptor inhibitors. Consequently the most effective treatment is amiloride. This drug is not used in pregnancy, as it has not been sufficiently studied during gestation. However for pregnant LS patient amiloride is the most effective drug in decreasing blood pressure. Herein we report the case of a LS patient, who has been followed up by a multidisciplinary teamwork during her first pregnancy. Hypertension worsened after the 25th week of gestation and amiloride was safely administered, firstly in combination with hydrochlorothiazide (the only formulation commercially available in Italy) and, thereafter, as a single drug. Genetic testing was performed in the patient's family in order to support diagnosis and clinical management.
