Abstract
OBJECTIVE To identify strategies for reducing neonatal and maternal morbidity associated with intrahepatic cholestasis pregnancy (ICP). MATERIAL AND METHODS The quality of evidence of the literature was assessed following the GRADE methodology with questions formulated in the PICO format (Patients, Intervention, Comparison, Outcome) and outcomes defined a priori and classified according to their importance. An extensive bibliographic search was performed on PubMed, Cochrane, EMBASE and Google Scholar databases. The quality of the evidence was assessed (high, moderate, low, very low) and a (i) strong or (ii) weak recommendations or (iii) no recommendation were formulated. The recommendations were reviewed in two rounds with external reviewers (Delphi survey) to select the consensus recommendations. RESULTS Of the 14 questions (from 12 PICO questions and one definition question outside the PICO format), there was agreement between the working group and the external reviewers on 14 (100%). The level of evidence of the literature was insufficient to provide a recommendation on two questions. ICP is defined by the occurrence of suggestive pruritus (palmoplantar, nocturnal) associated with a total bile acid level>10μmol/L or an alanine transaminase level above 2N after ruling out differential diagnoses. In the absence of suggestive symptoms of a differential diagnosis, it is recommended not to carry out additional biological or ultrasound tests. In women with CIP, ursodeoxycholic acid is recommended to reduce the intensity of maternal pruritus (Strong recommendation. Quality of the evidence moderate) and to decrease the level of total bile acids and alanine transaminases. (Strong recommendation. Quality of the evidence moderate). S-adenosyl-methionine, dexamethasone, guar gum or activated charcoal should not be used to reduce the intensity of maternal pruritus (Strong recommendation. Quality of evidence low), and there is insufficient data to recommend the use of antihistamines (No recommendation. Quality of evidence low). Rifampicin (Weak recommendation. Very low quality of evidence) or plasma exchange (Strong recommendation. Very low quality of evidence) should not be used to reduce maternal pruritus and perinatal morbidity. Serum monitoring of bile acids is recommended to reduce perinatal morbidity and mortality (stillbirth, prematurity) (Low recommendation. Quality of the evidence low). The level of evidence is insufficient to determine whether fetal heart rate or fetal ultrasound monitoring are useful to reduce perinatal morbidity (No recommendation). Birth is recommended when bile acid level is above 99μmol/L from 36 weeks gestation to reduce perinatal morbidity, in particular stillbirth. When bile acid level is above 99μmol/L is below 100μmol/L, women should be informed that induction of labor could be considered 37 and 39 weeks gestation to reduce perinatal morbidity. (Strong recommendation. Quality of evidence low). In postpartum, total bile acids and alanine transaminases level should be checked and normalized before prescribing estrogen-progestin contraception, ideally with a low estrogen dose (risk of recurrence of pruritus and cytolysis) (Low recommendation. Quality of evidence very low). CONCLUSION Although the quality of evidence regarding ICP gestational cholestasis remains low, there is a strong consensus in France, as shown by our Delphi study, on how to manage women with ICP. The reference first-line treatment is ursodeoxycholic acid.

Abstract
OBJECTIVES Intrahepatic cholestasis of pregnancy (ICP) is complicated by adverse fetal outcomes and even fetal death, the mechanism remains unclear. This study aims at evaluating the differential expression of mTORC2-AKT-IP3R signaling pathway, which accurately regulate Ca2+ transfer across mitochondria-associated membranes (MAMs) and determine the stress intensity experienced by endoplasmic reticulum (ER) and mitochondria, in patients diagnosed with ICP. METHODS We combined western blot analysis and placental immunofluorescence co-localization detection to assess the expression and co-localization of the mTORC2-AKT-IP3R signaling pathway in severe (maternal total bile acid (TBA) levels ≥40 μmol/L) and mild (maternal TBA 10-40 μmol/L) ICP. RESULTS Compared with the control and mild ICP groups, phosphorylated protein kinase B (p-AKT) levels were significantly upregulated in the severe ICP group. Placental Rictor levels were lower in the mild ICP group than in the control group and were further downregulated in the severe ICP group. IP3R3 and p-IP3R3 levels were lower in placentas in the severe ICP group than in those in the mild ICP and control groups. Moreover, the co-localization of IP3R3 and p-AKT in patients in the mild and severe ICP groups was significantly elevated compared with that in patients in the control group. CONCLUSIONS In patients with severe ICP, limited expression of Rictor and elevated p-AKT levels would suppress IP3R3/p-IP3R3 levels in MAMs. This inhibition might influence the transportation of Ca2+ from the ER to the mitochondria, thus weaken the stress adaptation associated with MAMs. Our results reveal the possible pathophysiological mechanism of adverse fetal outcomes in ICP.

Am J Obstet Gynecol 2023; 229:453.e1-453.e8. [PMID: 37348778 PMCID: PMC10651178 DOI: 10.1016/j.ajog.2023.06.036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Revised: 06/14/2023] [Accepted: 06/15/2023] [Indexed: 06/24/2023]
Abstract
BACKGROUND Intrahepatic cholestasis of pregnancy is associated with a 4- to 10-fold increase in the risk of stillbirth in the absence of intervention, leading to recommendations for antenatal assessment, ursodiol use, and often preterm or early term delivery. OBJECTIVE This study aimed to determine whether current management strategies for intrahepatic cholestasis of pregnancy mitigate the elevated risk of stillbirth at a population level. STUDY DESIGN This was a retrospective cohort study using the 2015-2020 National Readmissions Database, an administrative database developed by the United States Agency for Healthcare Research and Quality. Our study identified delivery hospitalizations, gestational age at delivery, occurrence of intrahepatic cholestasis of pregnancy and stillbirth, and comorbid conditions using the International Classification of Diseases diagnosis and procedure codes. Moreover, this study compared the timing of delivery and stillbirth rates of pregnant patients with intrahepatic cholestasis of pregnancy vs those without intrahepatic cholestasis of pregnancy at the time of delivery hospitalization. RESULTS This study identified a cohort of 9,987,705 delivery hospitalizations in the National Readmissions Database, corresponding to a weighted national estimate of 18,609,207 births. Of these births, 152,040 (0.8%) were noted to have an intrahepatic cholestasis of pregnancy diagnosis. Patients with an intrahepatic cholestasis of pregnancy diagnosis were older, with small differences in comorbidities, such as a higher rate of gestational diabetes mellitus, than patients without an intrahepatic cholestasis of pregnancy diagnosis at delivery hospitalization. The overall rates of stillbirth were lower among those with intrahepatic cholestasis of pregnancy than among those without intrahepatic cholestasis of pregnancy (252 vs 386 per 100,000 deliveries; risk difference, 133 fewer per 100,000 deliveries; 95% confidence interval, 98-170), a finding that persisted after adjustment for insurance status, socioeconomic factors, and comorbid conditions (risk difference, 160 fewer stillbirths per 100,000 deliveries; 95% confidence interval, 127-194). Furthermore, although patients with intrahepatic cholestasis of pregnancy were more likely to deliver before term than those without intrahepatic cholestasis of pregnancy (30.1% vs 9.3%; P<.001), increased rates of stillbirth were not noted at any point after stratification of the cohort by gestational age at delivery. CONCLUSION Patients with intrahepatic cholestasis of pregnancy diagnosis codes delivered earlier than those without intrahepatic cholestasis of pregnancy diagnosis codes, but the percentage of births affected by stillbirth was lower, even when stratifying for gestational age at birth. These results may provide reassurance to patients receiving an intrahepatic cholestasis of pregnancy diagnosis that current management does mitigate stillbirth risk in intrahepatic cholestasis of pregnancy.

Abstract
The aims of our study were to evaluate the maternal and fetal outcomes of intrahepatic cholestasis of pregnancy (ICP). In this observational, retrospective case-control study, we included all pregnant women who gave birth with a diagnosis of ICP between January 2010 and December 2020 at the Unit of Obstetrics and Gynecology, University Hospital of Messina. The data were compared with those from a control group of pregnant women who did not have ICP. One hundred twenty-nine and eighty-five patients were included, respectively, in the study and in the control group. There was a significant difference between the two groups in the incidence of hypothyroidism, thrombophilia, gestational diabetes, gestational hypertension, postpartum hemorrhage, and preterm delivery, which were more frequent in the ICP patients. No neonatal adverse events were recorded, although a significant difference in the meconium-stained amniotic fluid condition was noted. After a 24-month follow-up, 48/129 patients with ICP accepted to be reassessed by liver ultrasound, elastographic examination, and liver function blood tests. No patient showed signs of chronic liver disease. This study confirmed a higher probability of adverse short-term maternal outcomes in ICP pregnant patients, but a lower probability of adverse short-term fetal outcomes and the absence of a long-term maternal risk of chronic liver disease.

BMC Pregnancy Childbirth 2022; 22:269. [PMID: 35361142 PMCID: PMC8969330 DOI: 10.1186/s12884-022-04610-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Accepted: 03/23/2022] [Indexed: 11/23/2022] Open
Abstract
Background Intrahepatic cholestasis of pregnancy is one of the common complications during pregnancy, and ursodeoxycholic acid has been recommended as the first-line drug. However, if the assisted reproductive technology may increase adverse perinatal outcomes of twin pregnancies complicated by intrahepatic cholestasis is disputed, we aimed to investigate perinatal outcomes between twin pregnancies by assisted reproductive technology versus spontaneous conception, based on these women accepted ursodeoxycholic acid treatment. Methods From January 2014 to January 2019, we retrospectively analysed the clinical data of twin pregnant women with intrahepatic cholestasis, excluding those who did not receive ursodeoxycholic acid treatment. In total, 864 women were included, among whom 500 conceived by assisted reproductive technology and 364 conceived by spontaneous conception. The primary assessment for perinatal outcomes included premature birth, meconium-stained amniotic fluid, low Apgar score, neonatal intensive care unit and still birth, and secondary indicators were serum bile acid and liver enzymes level during medication, so we also finished subgroup analysis based on different elevated bile acid level and drug usage. The statistical analysis was performed by SPSS 22.0. Results The study demonstrated that compared to spontaneous conception, assisted reproductive technology conceived twin pregnancies diagnosed as intrahepatic cholestasis earlier (p = 0.003), and lower birth weight (p = 0.001), less incidence of preterm delivery (p = 0.000) and neonatal intensive care unit admission (p = 0.001), but the rate of meconium-stained amniotic fluid, low Apgar score and still birth have no statistic differences. Moreover, the subgroup analysis showed no significant difference in elevated bile acid levels and medication between assisted reproductive technology and spontaneous conception groups. Conclusions The assisted reproductive technology may increase the risk of early-onset intrahepatic cholestasis in twin pregnancies, but it does not seem to increase adverse effects on bile acid levels and perinatal outcomes. Regardless of ursodeoxycholic acid used alone or combination, the effect of bile acid reduction and improving perinatal outcomes in twin pregnancies is limited. Our conclusions still need more prospective randomized controlled studies to confirm.

Abstract
Vanishing twin syndrome (VTS), defined by first-trimester spontaneous loss of a twin, is a common phenomenon with a reported prevalence of 15-35% of twin pregnancies. The etiology of VTS is obscure. Still, several risk factors have been identified, including an increased number of embryos transferred in pregnancies conceived by in vitro fertilization, an initial increased number of gestational sacs and advanced maternal age. The effect of VTS on obstetric and perinatal outcomes is controversial. Several studies have reported that pregnancies with VTS were associated with increased risk for preterm birth and small for gestational age neonates compared to singleton pregnancies, while others showed no difference in perinatal outcomes. The prevalence of placental vascular and anatomic abnormalities such as small placentas was higher in VTS. These findings lay an essential foundation for understanding how this phenomenon affects obstetric and perinatal outcomes of the surviving pregnancy.

Abstract
OBJECTIVE To determine the obstetrical outcomes of women delivered for the diagnosis of intrahepatic cholestasis of pregnancy (ICP). METHODS Retrospective study of singleton pregnancies diagnosed with ICP between 1 May 2014 and 31 December 2017. Population was analyzed based on bile acids: normal (<10 µmol/L), mild (10 to 40 µmol/L), moderate-severe (>40 µmol/L), and not obtained. Receiver operating characteristic curves established critical values for aspartate aminotransferase (AST) and alanine aminotransferase (ALT) to predict elevated bile acids. Statistical analyses included χ2 for categorical variables and ANOVA for continuous variables. All tests used a 2-sided α level of significance of .05. RESULTS Bile acids were normal in 39 (45.9%) women, 30 (35.3%) had mild cholestasis, 10 (11.8%) had moderate-severe cholestasis and not obtained for six (7%) women. Gestational diabetes was more common in mild cholestasis (p = .03). There were no differences in demographics, clinical presentation, obstetric interventions and neonatal outcomes. Bile acids took 5-6 days to result. Rate of labor inductions was high in all groups. Postpartum complications occurred in four women in the normal group and in one woman in the mild cholestasis group. Five (12.8%) neonates in the normal group, six (20%) in the mild group, and one (10%) in the severe group were admitted to the NICU. There was no fetal asphyxia, no 5-minute Apgar score <7, and no perinatal deaths. An AST of 27.5 IU/L (p = .002) with sensitivity of 81% and specificity of 76%, and an ALT of 26.7 IU/L (p = .004) with sensitivity of 78% and specificity of 68% predicted elevated bile acids. Improving the sensitivity of AST and ALT to 95%, the ROC curve identified an AST of 62 IU/L with a specificity, positive and negative predictive values of 32, 58 and 86%, respectively; and an ALT of 106 IU/L with a specificity, positive and negative predictive values of 27, 57 and 83%, respectively. CONCLUSIONS ICP should not be presumed in patients with pruritus. This practice may lead to early term delivery and associated complications.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) is the most common liver disease specific to pregnancy. The cardinal symptom of pruritus and a concomitant elevated level of bile acids in the serum and/or alanine aminotransferase (ALT) are suggestive for the diagnosis. Overall, the maternal prognosis is good. The fetal outcome depends on the bile acid level. ICP is associated with increased risks for adverse perinatal outcomes, including preterm delivery, meconium-stained amniotic fluid, and stillbirth. Acute fetal asphyxia and not chronic uteroplacental dysfunction leads to stillbirth. Therefore, predictive fetal monitoring is not possible. While medication with ursodeoxycholic acid (UDCA) improves pruritus, it has not been shown to affect fetal outcome. The indication for induction of labour depends on bile acid levels and gestational age. There is a high risk of recurrence in subsequent pregnancies.

Abstract
PURPOSE To compare the clinical characteristics of pregnant women and perinatal outcomes with or without recurrent severe intrahepatic cholestasis of pregnancy (sICP), and identify possible factors associated with disease recurrence. METHODS A retrospective study of 164,603 deliveries was performed to identify pregnant women diagnosed with sICP in the previous pregnancy from January 2012 to December 2020. Eligible patients were divided into two subgroups according to the status of disease recurrence in the second pregnancy: recurrent severe ICP (r-sICP) and non-recurrent severe ICP (nr-sICP). Demographics, clinical characteristics, maternal and perinatal outcomes, and potential factors linked to disease recurrence were analyzed. RESULTS Totally 118 patients were enrolled and respectively classified into the r-sICP group (n = 63) and the nr-sICP group (n = 55). The proportion of hepatitis B virus (HBV) infection (HBsAg+, HBeAg+, HBcAb+) and early-onset ICP (<28 weeks) in the r-sICP group in the previous pregnancy were higher than those in the nr-sICP group. In the second delivery, neonatal outcomes in the r-sICP group were worse than those in the nr-sICP group. Logistic regression analysis of predictive factors for disease recurrence in the second delivery revealed that the combination of HBV infection and early-onset ICP in the previous delivery had the steepest receiver-operating characteristic (ROC) curve value 0.720 (95%CI: 0.629-0.812). CONCLUSION Patients with sICP displayed a higher recurrence rate in the second pregnancy. Being <28 weeks at the time of ICP diagnosis and having HBV infection in the previous delivery appear to be independent predictive factors for disease recurrence of sICP.

Abstract
Die Schwangerschaftscholestase („intrahepatic cholestasis of pregnancy“, ICP) ist die häufigste schwangerschaftsspezifische Lebererkrankung. Das Leitsymptom Juckreiz sowie eine begleitende Serumkonzentrationserhöhung von Gallensäuren und/oder der Alaninaminotransferase (ALT) sind wegweisend in der Diagnosestellung. Die mütterliche Prognose ist gut. Das fetale Outcome ist abhängig von der Gallensäurenkonzentration. Die ICP ist dabei sowohl mit Frühgeburt als auch mit intrauterinem Fruchttod (IUFT) assoziiert. Dieser ist Folge einer akuten fetalen Asphyxie, nicht einer chronischen uteroplazentaren Dysfunktion. Ein prädiktives Monitoring, z. B. durch Kardiotokographie (CTG) oder Ultraschall gibt es nicht. Eine medikamentöse Therapie mit Ursodeoxycholsäure (UDCA) bessert den Juckreiz, aber beeinflusst das fetale Outcome nicht nachweislich. Eine Entbindungsindikation ist in Abhängigkeit von Gallensäurenkonzentration und Gestationsalter gegeben. In Folgeschwangerschaften besteht ein hohes Wiederholungsrisiko.

Abstract
Intrahepatic cholestasis of pregnancy is a hepatic disorder characterized by pruritus and an elevation in serum bile acid levels. Although intrahepatic cholestasis of pregnancy poses little risk for women, this condition carries a significant risk for the fetus, including complications such as preterm delivery, meconium-stained amniotic fluid, and stillbirth. The purpose of this Consult is to review the current literature on intrahepatic cholestasis of pregnancy and provide recommendations based on the available evidence. The recommendations by the Society for Maternal-Fetal Medicine are as follows: (1) we recommend measurement of serum bile acid and liver transaminase levels in patients with suspected intrahepatic cholestasis of pregnancy (GRADE 1B); (2) we recommend that ursodeoxycholic acid be used as the first-line agent for the treatment of maternal symptoms of intrahepatic cholestasis of pregnancy (GRADE 1A); (3) we suggest that patients with a diagnosis of intrahepatic cholestasis of pregnancy begin antenatal fetal surveillance at a gestational age when delivery would be performed in response to abnormal fetal testing results or at the time of diagnosis if the diagnosis is made later in gestation (GRADE 2C); (4) we recommend that patients with total bile acid levels of ≥100 μmol/L be offered delivery at 36 0/7 weeks of gestation, given that the risk of stillbirth increases substantially around this gestational age (GRADE 1B); (5) we recommend delivery between 36 0/7 and 39 0/7 weeks of gestation for patients with intrahepatic cholestasis of pregnancy and total bile acid levels of <100 μmol/L (GRADE 1C); (6) we recommend administration of antenatal corticosteroids for fetal lung maturity for patients delivering before 37 0/7 weeks of gestation if not previously administered (GRADE 1A); (7) we recommend against preterm delivery at <37 weeks of gestation in patients with a clinical diagnosis of intrahepatic cholestasis of pregnancy without laboratory confirmation of elevated bile acid levels (GRADE 1B).

Abstract
INTRODUCTION Previous studies of fetal effects have suggested that intrahepatic cholestasis of pregnancy is associated with a higher rate of adverse neonatal outcomes including preterm birth, neonatal respiratory distress syndrome, meconium-stained amniotic fluid, neonatal intensive care unit admission, and stillbirth. The objective was to compare the neonatal and maternal consequences in pregnancies affected by intrahepatic cholestasis and normal pregnancies. MATERIAL AND METHODS This case-control study compares pregnancies affected by intrahepatic cholestasis (pruritus and bile acid ≥ 10 μmol/L) with low-risk pregnancies managed between December 2006 and December 2014 at a French university hospital center. RESULTS There were 83 (59.3%) cases of mild cholestasis (10≤ BA ≤39 μmol/L), 46 (32.8%) of moderate cholestasis (40≤ BA ≤99 μmol/L), and 11 (7.9%) of severe cholestasis (BA ≥100 μmol/L). No in utero fetal deaths occurred in the 140 women with cholestasis or the 560 controls analyzed. The rate of respiratory distress syndrome was higher in neonates of women with intrahepatic cholestasis (17.1% vs. 4.6%, P<0.001; crude OR 4.46 (CI95% 2.49-8.03)). This risk was also significant after adjustment for gestational age at birth and mode of delivery, adjusted OR 2.56 (CI95%1.26-5.18). The postpartum hemorrhage rate was twice as high among the case mothers (25% versus 14.1% for controls, P = 0.002). CONCLUSION After adjustment on the confounding factors we found a higher rate of respiratory distress syndrome and neonatal morbidity among neonates of the cholestasis group.

Abstract
OBJECTIVE To identify laboratory data that correlates with poor perinatal outcomes. METHODS A retrospective chart review of women with intrahepatic cholestasis of pregnancy (ICP), admitted for delivery between January 1, 2013 and December 31, 2017, was performed. Chi-square, student's t-test, and ANOVA statistical analysis was performed. The receiver-operator characteristic curves were plotted for the prediction of each category of perinatal outcome and the areas under the curves were determined. All p-values were two-sided, and p < 0.05 was considered statistically significant. RESULTS Analysis of the 61 ICP cases showed no occurrence of the intrauterine fetal demise (IUFD), stillbirth, abruption, or neonatal demise. ROC curve analysis revealed a statistically significant correlation between bile acid and AST levels and perinatal outcomes. A bile acid (BA) level equal to or greater than 37μmol/L strongly predicted spontaneous preterm labor in women affected by ICP with a sensitivity of 100% and specificity of 60.70% (p = 0.002). A BA level equal to or greater than 42μmol/L strongly predicted meconium-stained amniotic fluid with a sensitivity of 85.70% and specificity of 66.70% (p = 0.006). AST levels equal to or greater than 62 IU/L strongly predicted NICU admission with a sensitivity of 81.30% and specificity of 62.20% (p = 0.002). AST levels equal to or greater than 75 IU/L strongly predicted hyperbilirubinemia in the neonates with a sensitivity of 87.50% and specificity of 69.80% (p = 0.001). CONCLUSIONS There is a statistically significant correlation between elevated BA and elevated AST levels and adverse perinatal outcomes.

Abstract
Objective This study aimed to report the maternal and fetal outcomes in women with intrahepatic cholestasis of pregnancy (ICP). Materials and Methods The maternal and fetal outcomes in 70 consecutive women who gave birth at Ataturk University Hospital between January 2012 and December 2017 were assessed. The clinical diagnosis of ICP and diagnosis confirmed post-delivery when all the symptoms regressed and laboratory parameters returned to normal was utilized. Results Liver transaminases were elevated in 61 (87%) women. The median week of delivery was 37 (range, 26-42) and the preterm delivery rate was 40% (28 women delivered spontaneously at ≤36 weeks of gestation). Preeclampsia was noted in 8 (11%) women. There were no cases of stillbirth or neonatal death. Conclusion The rate of stillbirth does not increase in women with ICP. However, further investigations are needed to determine if this result is related to preterm birth.

Abstract
OBJECTIVE To evaluate enzymatic total serum bile acid quantification as a monitoring strategy for women with intrahepatic cholestasis of pregnancy (ICP) treated with ursodeoxycholic acid (UDCA). DESIGN Cohort. SETTING One UK university hospital. POPULATION 29 ICP cases treated with UDCA. METHODS Serial samples were collected prospectively throughout gestation. Total serum bile acids were measured enzymatically and individual bile acids by high-performance liquid chromatography-tandem mass spectrometry. Data were log-transformed and analysed with random effects generalised least square regression. MAIN OUTCOME MEASURES The relationship between enzymatic total bile acid measurements and individual bile acid concentrations after UDCA treatment. RESULTS In untreated women, cholic acid was the principal bile acid (51%) and UDCA concentrations were <0.5%, whereas UDCA constituted 60% (IQR 43-69) of serum bile acids following treatment and cholic acid fell to <20%. Changes in the total bile acid measurement reflected similar alterations in the concentrations of the pathologically elevated bile acids, e.g. a two-fold increase in enzymatic total bile acids is accompanied by approximately a two-fold increase in cholic acid and chenodeoxycholic acid at most UDCA doses (P < 0.001). Most of the effects of UDCA on cholic acid occur in the first week of treatment (60% relative reduction, P = 0.025, 95% CI 0.2-0.9, from 10 micromol/l (4.7-17.6) to 3.5 micromol/l (1.4-7.5). CONCLUSION Ursodeoxycholic acid becomes the main component of the bile acid measurement after treatment. Enzymatic total bile acid assays are good predictors of both cholic acid and chenodeoxycholic acid, the primary bile acids that are raised prior to treatment. TWEETABLE ABSTRACT Ursodeoxycholic acid constitutes approximately 60% of the bile acid measurement and reduces pathological cholic acid in treated women.

Abstract
PURPOSE To determine the rate of obstetric and neonatal complications associated with intrahepatic cholestasis of pregnancy in twin versus singleton gestations. METHODS A retrospective cohort study including patients diagnosed with intrahepatic cholestasis of pregnancy at a single tertiary center between 2011 and 2016. Women were allocated into two groups: twin pregnancies (n = 56) and singleton pregnancies (n = 186). Obstetric and neonatal outcomes were compared between the two groups. RESULTS Intrahepatic cholestasis of pregnancy was diagnosed earlier in gestation in twin compared to singleton pregnancies (33.1 ± 2.8 vs. 35.1 ± 3.0 weeks, respectively; adjusted P < 0.001). Maternal serum levels of fasting total bile acids were significantly higher in twin pregnancies compared to singletons [27 (IQR 16-44) vs. 16 (IQR 10-26) µmol/L, respectively; P = 0.01]. None of the pregnancies in our cohort was complicated by fetal death. Apgar score at 5 min and umbilical artery and vein PH at delivery were comparable between the two groups. CONCLUSIONS Intrahepatic cholestasis of pregnancy in twin pregnancies appears to be more severe compared to singletons, as reflected by an earlier presentation and higher levels of maternal serum total bile acids. Large prospective studies are required to customize a management strategy specific for women with twin pregnancies and intrahepatic cholestasis of pregnancy.

Abstract
BACKGROUND Intrahepatic cholestasis of pregnancy is a pregnancy-specific liver disorder, possibly associated with an increased risk of severe fetal adverse events. Total serum bile acids (TSBA) concentration, alone or in combination with serum aminotransferases, have been the most often used biomarkers for the diagnosis of intrahepatic cholestasis of pregnancy in clinical practice. Serum bile acid profile, composed of primary or secondary, conjugated or non-conjugated bile acids, may provide more specific disease information. OBJECTIVES To assess and compare, independently or in combination, the diagnostic accuracy of total serum bile acids or serum bile acids profile, or both, for the diagnosis of intrahepatic cholestasis of pregnancy in pregnant women, presenting with pruritus. To define the optimal cut-off values for components of serum bile acid profile; to investigate possible sources of heterogeneity. SEARCH METHODS We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Hepato-Biliary Group Diagnostic Test Accuracy Studies Register, the Cochrane Library, MEDLINE Ovid, Embase Ovid, Science Citation Index Expanded, Conference Proceedings Citation Index - Science, BIOSIS, CINAHL, two Chinese databases (CKNI, VIP), Latin American and Caribbean Health Sciences Literature (LILACS), Scientific Electronic Library Online (SciELO), Evidence Search: Health and Social Care by the National Institute for Health and Care Excellence (NICE), the World Health Organization (WHO) Reproductive Health Library (RHL), and the Turning Research into Practice database (TRIP). The most recent date of search was 6 May 2019. We identified additional references by handsearching the references of articles, meta-analyses, and evidence-based guidelines retrieved from the computerised databases, on-line trial registries, and grey literature through OpenSIGLE, National Technical Information Service (NTIS), ProQuest Dissertations & Thesis Database, and Index to Theses in Great Britain and Ireland. SELECTION CRITERIA Prospective or retrospective diagnostic case-control or cross-sectional studies, irrespective of publication date, format, and language, which evaluated the diagnostic accuracy of total serum bile acids (TSBA) or components of serum bile acid profile for the diagnosis of intrahepatic cholestasis of pregnancy in pregnant women of any age or ethnicity, in any clinical setting, symptomatic for pruritus. DATA COLLECTION AND ANALYSIS We selected studies by reading titles, abstracts, or full texts, and assessing their fulfilment of our inclusion criteria. We emailed primary authors to request missing data or individual participant data. Having extracted data from each included study, we built the two-by-two tables for each primary study and for all the index tests considered. We estimated sensitivity and specificity with their 95% confidence intervals (CI). We presented data in coupled forest plots, showing sensitivities and specificities of each study, and we plotted the studies in the Receiver Operating Characteristic (ROC) space. We performed meta-analyses adopting the hierarchical summary ROC model (HSROC) or the bivariate model to meta-analyse the data. We made indirect comparisons of the considered index tests by adding the index tests as covariates to the bivariate or HSROC models. We performed heterogeneity analysis and sensitivity analysis on studies assessing TSBA accuracy. We used Review Manager 5 (RevMan 5) and SAS statistical software, release 9.4 (SAS Institute Inc., Cary, NC, USA), to perform all statistical analyses. We used QUADAS-2 domains to assess the risk of bias of the included studies. MAIN RESULTS Our search yielded 5073 references, but at the end of our selection process, only 16 studies fulfilled the review inclusion criteria. Nine of these provided individual participant data. We analysed only data concerning TSBA, cholic acid (CA), glycocholic acid (GCA), chenodeoxycholic acid (CDCA), and CA/CDCA because the remaining planned index tests were assessed in few studies. Only one study had low risk of bias in all four QUADAS-2 domains. The most biased domains were the patient sampling and the reference standard domains. When considering all studies with a cut-off of 10 μmol/L, TSBA overall sensitivity ranged from 0.72 to 0.98 and specificity ranged from 0.81 to 0.97. After a sensitivity analysis excluding case-control studies, TSBA sensitivity ranged from 0.48 to 0.66 and specificity from 0.52 to 0.99. After a sensitivity analysis excluding studies in which TSBA was part of the reference standard, TSBA sensitivity ranged from 0.49 to 0.65 and specificity from 0.53 to 0.99. We found the estimates of the overall accuracy for some serum bile acid components (CA, GCA, CDCA, and CA/CDCA) to be imprecise, with the CI for sensitivity and specificity very wide or impossible to calculate. Indirect comparisons between serum bile acid profile components and TSBA were not statistically significant. None of the heterogeneity analysis performed was statistically significant, except for the timing of assessment of TSBA (onset of symptoms, peak value among multiple assessments, delivery) but without clinically relevant results. We could not analyse the diagnostic accuracy of combinations of index tests because none of the included studies carried them out, and because of the small number of included studies. AUTHORS' CONCLUSIONS The overall high risk of bias, the existing concern regarding applicability of the results in clinical practice, and the great heterogeneity of the results in the included studies prevents us from making recommendations and reaching definitive conclusions at the present time. Thus, we do not find any compelling evidence to recommend or refute the routine use of any of these tests in clinical practice. So far, the diagnostic accuracy of TSBA for intrahepatic cholestasis of pregnancy might have been overestimated. There were too few studies to permit a precise estimate of the accuracy of serum bile acid profile components. Further primary clinical research is mandatory. We need both further phase II and phase III diagnostic studies.

Abstract
BACKGROUND AND OBJECTIVE Although many meta-analyses have evaluated the pharmacotherapy of intrahepatic cholestasis of pregnancy (ICP) and recommended ursodeoxycholic acid (UDCA) as an effective treatment, the defect of the pair-wise analyses and the mixture of the control group made the outcome uncertain and unclear. We aimed to employ Bayesian network meta-analysis (NMA) to compare the maternal and fetal outcomes after UDCA, S-adenosylmethionine (SAMe) mono-therapy or the combination treatment of these two drugs for ICP patients. METHODS Multiple electronic database searches were conducted for articles published up to 1 September 2018. The relevant information was extracted from the published reports with a predefined data extraction sheet, and the risk of bias was assessed with the Cochrane risk-of-bias tool. Poisson Bayesian network meta-analysis was employed to identify the synthesized evidence from the relevant trials, with reporting hazard risks (HRs) and 95% credible intervals (CrIs). RESULTS The pooled outcomes of the 13 randomized controlled trials (RCTs) with 625 participants indicated that none of the three regimens can significantly improve maternal and fetal outcomes. CONCLUSION This NMA of the RCTs clarified that the current intervention has no favorable effect on pruritus and other symptoms in ICP patients.

Abstract
BACKGROUND Intrahepatic cholestasis of pregnancy is associated with adverse perinatal outcomes, but the association with the concentration of specific biochemical markers is unclear. We aimed to quantify the adverse perinatal effects of intrahepatic cholestasis of pregnancy in women with increased serum bile acid concentrations and determine whether elevated bile acid concentrations were associated with the risk of stillbirth and preterm birth. METHODS We did a systematic review by searching PubMed, Web of Science, and Embase databases for studies published from database inception to June 1, 2018, reporting perinatal outcomes for women with intrahepatic cholestasis of pregnancy when serum bile acid concentrations were available. Inclusion criteria were studies defining intrahepatic cholestasis of pregnancy based upon pruritus and elevated serum bile acid concentrations, with or without raised liver aminotransferase concentrations. Eligible studies were case-control, cohort, and population-based studies, and randomised controlled trials, with at least 30 participants, and that reported bile acid concentrations and perinatal outcomes. Studies at potential higher risk of reporter bias were excluded, including case reports, studies not comprising cohorts, or successive cases seen in a unit; we also excluded studies with high risk of bias from groups selected (eg, a subgroup of babies with poor outcomes were explicitly excluded), conference abstracts, and Letters to the Editor without clear peer review. We also included unpublished data from two UK hospitals. We did a random effects meta-analysis to determine risk of adverse perinatal outcomes. Aggregate data for maternal and perinatal outcomes were extracted from case-control studies, and individual patient data (IPD) were requested from study authors for all types of study (as no control group was required for the IPD analysis) to assess associations between biochemical markers and adverse outcomes using logistic and stepwise logistic regression. This study is registered with PROSPERO, number CRD42017069134. FINDINGS We assessed 109 full-text articles, of which 23 studies were eligible for the aggregate data meta-analysis (5557 intrahepatic cholestasis of pregnancy cases and 165 136 controls), and 27 provided IPD (5269 intrahepatic cholestasis of pregnancy cases). Stillbirth occurred in 45 (0·83%) of 4936 intrahepatic cholestasis of pregnancy cases and 519 (0·32%) of 163 947 control pregnancies (odds ratio [OR] 1·46 [95% CI 0·73-2·89]; I2=59·8%). In singleton pregnancies, stillbirth was associated with maximum total bile acid concentration (area under the receiver operating characteristic curve [ROC AUC]) 0·83 [95% CI 0·74-0·92]), but not alanine aminotransferase (ROC AUC 0·46 [0·35-0·57]). For singleton pregnancies, the prevalence of stillbirth was three (0·13%; 95% CI 0·02-0·38) of 2310 intrahepatic cholestasis of pregnancy cases in women with serum total bile acids of less than 40 μmol/L versus four (0·28%; 0·08-0·72) of 1412 cases with total bile acids of 40-99 μmol/L (hazard ratio [HR] 2·35 [95% CI 0·52-10·50]; p=0·26), and versus 18 (3·44%; 2·05-5·37) of 524 cases for bile acids of 100 μmol/L or more (HR 30·50 [8·83-105·30]; p<0·0001). INTERPRETATION The risk of stillbirth is increased in women with intrahepatic cholestasis of pregnancy and singleton pregnancies when serum bile acids concentrations are of 100 μmol/L or more. Because most women with intrahepatic cholestasis of pregnancy have bile acids below this concentration, they can probably be reassured that the risk of stillbirth is similar to that of pregnant women in the general population, provided repeat bile acid testing is done until delivery.

Abstract
AIM Intrahepatic cholestasis of pregnancy (ICP) is reported to be associated with an increased risk of sudden fetal death. The possible mechanism is thought to be cardiac arrhythmia. Prolonged QT interval of the electrocardiogram (ECG) is associated with arrhytmogenic events. The aim of the study was to compare the fetal ECG QT interval during labor in pregnancies complicated with ICP to healthy controls. METHODS The fetal ECG and QT interval was reviewed retrospectively. The intrapartum QT interval was measured in 61 fetuses born to mothers with ICP and in a control group of similar size. The corrected QT interval (QTc) was calculated using Bazett's formula: QT/√RR. The occurrence of ST segment depression was also included in the analysis. RESULTS The groups were similar regarding to maternal age, parity, BMI, gestational age and smoking habits. The rate of labor induction was significantly higher in ICP patients (P < 0.001). The QTc at the beginning and the end of recording was analyzed and there were no significant differences in these values between the ICP patients and healthy controls (P = 0.467). Most ICP patients used ursodeoxycholic acid (UDCA) for mediation. We analyzed separately patients who had elevated liver enzymes before labor. No significant differences in the QTc were noted in these patients either. Nor were there any significant ST depressions in ICP patients. CONCLUSIONS The etiology of adverse perinatal outcome and even sudden fetal death in ICP is still controversial. No differences in QTc intervals and ST waveforms during labor were found in our study material.

Abstract
AIM To analyze the common causes of liver abnormalities during pregnancy in Chinese women and their effects on maternal and fetal outcomes.
METHODS The CNKI, WANFANG database and VIP database were searched to collect all the literature on liver abnormalities during pregnancy published in Chinese during the past 20 years. The data were analyzed using R software and Stata software.
RESULTS Thirty-seven studies were included, with a total of 8367 cases. The results of meta-analysis showed that the common causes of liver abnormalities during pregnancy in Chinese women included hepatitis (39%; 95%CI: 30%-48%), pregnancy induced hypertension syndrome (17%; 10%-25%), intrahepatic cholestasis of pregnancy (ICP) (17%; 14%-19%), acute fatty liver of pregnancy (3%; 2%-4%), hyperemesis gravidarum (8%; 6%-11%), and HELLP syndrome (3%; 1%-5%). With regard to pregnancy outcomes with liver abnormalities caused by hepatitis, the probabilities of premature delivery, cesarean section, postpartum hemorrhage, fetal distress and perinatal death were 20%, 35%, 15%, 26% and 16%, respectively; the corresponding probabilities were 21%, 62%, 16%, 40% and 15% for pregnancy induced hypertension syndrome, and 36%, 70%, 15%, 35% and 16% for ICP. Abnormal liver function during pregnancy was associated with adverse pregnancy outcomes, and the OR values (95%CIs) were as follows: premature delivery, 4.48 (3.89-6.60); cesarean section, 3.75 (3.28-4.29); postpartum hemorrhage, 5.36 (4.07-7.05); fetal distress, 3.78 (3.16-4.53); perinatal death, 6.39 (3.27-12.49); pregnancy induced hypertension, 4.67 (3.44-6.35); asphyxia neonatorum, 3.07 (2.18-4.32).
CONCLUSION Hepatitis is the primary cause of abnormal liver function during pregnancy, followed by pregnancy induced hypertension syndrome and ICP. All of these increase the risk of mothers and infants during pregnancy and delivery.

Abstract
Pregnancy is associated with changes in normal physiology, including changes to the normal parameters for blood tests. Abnormal liver function tests are a common reason for referral to gastroenterology. However, in the pregnant patient, there are unique potential causes. It is of prime importance to be aware of pregnancy-specific liver diseases as they can be serious and progress rapidly affecting outcomes for both the mother and fetus. Here, we provide an overview of the manifestations of pregnancy-related liver diseases and discuss their potential consequences.

Abstract
Aim: Intrahepatic cholestasis of pregnancy (ICP) is the most common liver disease in pregnancy. Although it was shown that multiple pregnancy and hormone therapies increase the risk of ICP, there is limited information that compared spontaneous fertilization and in vitro fertilization (IVF) from the aspect of developing ICP. In our study, we investigated the potential relationship between ICP and IVF/ spontaneous pregnancy. Materials and methods: We reviewed the records (between June 2007 and December 2014) of pregnancies with ICP who were referred to gastroenterology clinics in three different hospitals. Fifty-nine pregnancies (43 spontaneous fertilization, 16 IVF) with ICP were analyzed from the aspect of age, fertilization type, multiple/singleton pregnancy, delivery week, and biochemical results. Results: We found that serum bile acid levels were higher in the IVF group than the spontaneous fertilization group (32.8 ± 20 vs 19.6 ± 19 μmol/L; p < 0.05). There was a significant inverse correlation between serum bile acid levels and gestational age (r = -0.42, p < 0.01) in the whole group. There was no difference between IVF and spontaneous fertilization groups in term of age, onset time of symptoms, serum alanine aminotransferase (ALT), alkaline phosphatase (ALP), total and direct bilirubin levels, prothrombin time (PT), international normalized ratio (INR), and platelet count. Conclusion: Our results suggest that the serum bile acid levels are higher in IVF than in spontaneous pregnancies with ICP, but its clinical implications are not clear. Further prospective studies with large number of ICP cases are needed to clarify the effect of IVF on ICP.

Abstract
OBJECTIVE The objective of this study is to examine perinatal outcomes associated with cholestasis of pregnancy according to bile acid level and antenatal testing practice. STUDY DESIGN Retrospective cohort study of women with symptoms and bile acid testing from 2005 to 2014. Women were stratified by bile acid level: no cholestasis (<10 μmol/L), mild (10-39 μmol/L), moderate (40-99 μmol/L), and severe (≥100 μmol/L). The primary outcome was composite neonatal morbidity (hypoxic ischemic encephalopathy, severe intraventricular hemorrhage, bronchopulmonary dysplasia, necrotizing enterocolitis, or death). RESULTS 785 women were included; 487 had cholestasis (347 mild, 108 moderate, 32 severe) and 298 did not. After controlling for gestational age (GA), severe cholestasis was associated with the composite neonatal outcome (aRR 5.6, 95% CI 1.3-23.5) and meconium-stained fluid (aRR 4.82, 95%CI 1.6-14.2). Bile acid levels were not correlated with the frequency of testing (p = .50). Women who underwent twice weekly testing were delivered earlier (p = .016) than women tested less frequently, but the difference in GA was ≤4 d. Abnormal testing prompting delivery was uncommon. Among women with cholestasis, there were three stillbirths. One of these women was undergoing antenatal testing, which was normal 1 d prior to the fetal demise. CONCLUSION Severe cholestasis is associated with neonatal morbidity which antenatal testing may not predict.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-specific disease, characterized by maternal pruritus and abnormal serum biochemistries in the late second and third trimester of pregnancy. The symptoms and abnormal biochemistries resolve rapidly after fetal delivery. As a diagnosis of exclusion, the diagnosis of ICP is based on unexplained pruritus with other causes and impaired liver function presenting with elevated serum liver transaminases and/or bile acids. It is considered as severe ICP when bile acid ≥ 40 μmol/L during pregnancy. The pathogenesis of ICP is still unclear. Adverse perinatal outcomes associated with ICP are focused on increased risk of preterm, meconium-stained amniotic fluid, and perinatal mortality. Unpredictable fetal hypoxia may result in intrauterine fetal death, fetal distress during birth and even stillbirth, and lead to an increase of iatrogenic preterm and cesarean section. The etiology and pathogenesis of fetal stress in ICP are not yet clarified, which may be associated with impaired infrastructure and decreased stress-compensatory in human utero-placental-fetal unit, and related with vascular constriction of chorionic veins and umbilical cord due to elevated bile acids in fetal serum and amniotic fluid. The essential measures of standard treatment of ICP include: (1) monitoring and evaluation of disease, uterine contraction and fetus; (2) prevention and treatment of uterine contraction; (3) treatment with ursodeoxycholic acid (500-1500 mg/d) alone or in combination with S-adenosylmehionine (800-1000 mg/d) or rifampicin (300-1200 mg/d) to promote drainage of bile acids; (4) promotion of fetal growth and lung development; (5) treatment with vitamin K1 before delivery to prevent maternal and fetal hemorrhage; (6) and timely termination of pregnancy. Gestational weeks, fetal condition and severity of disease need to be taken into account when obstetricians decide the time of termination. Elective early delivery is still an effective measure to avoid stillbirth during prolongation of gestational weeks.

Abstract
The farnesoid X receptor (Fxr) controls bile acid homeostasis by coordinately regulating the expression of synthesizing enzymes (Cyp7a1, Cyp8b1), conjugating enzymes (Bal, Baat) and transporters in the ileum (Asbt, Ostα/β) and liver (Ntcp, Bsep, Ostβ). Transcriptional regulation by Fxr can be direct, or through the ileal Fgf15/FGF19 and hepatic Shp pathways. Circulating bile acids are increased during pregnancy due to hormone-mediated disruption of Fxr signaling. While this adaptation enhances lipid absorption, elevated bile acids may predispose women to develop maternal cholestasis. The objective of this study was to determine whether short-term treatment of pregnant mice with GW4064 (a potent FXR agonist) restores Fxr signaling to the level observed in virgin mice. Plasma, liver and ilea were collected from virgin and pregnant mice administered vehicle or GW4064 by oral gavage. Treatment of pregnant mice with GW4064 induced ileal Fgf15, Shp and Ostα/β mRNAs, and restored hepatic Shp, Bal, Ntcp, and Bsep back to vehicle-treated virgin levels. Pregnant mice exhibited 2.5-fold increase in Cyp7a1 mRNA compared to virgin controls, which was reduced by GW4064. Similarly treatment of mouse primary hepatocytes with plasma isolated from pregnant mice induced Cyp7a1 mRNA by nearly 3-fold as compared to virgin plasma, which could be attenuated by co-treatment with either GW4064 or recombinant FGF19 protein. Collectively, these data reveal that repressed activity of intestinal and hepatic Fxr in pregnancy, as previously demonstrated, may be restored by pharmacological activation. This study provides the basis for a novel approach to restore bile acid homeostasis in patients with maternal cholestasis.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) is the most common liver disease during pregnancy, characterized by otherwise unexplained pruritus in late second and third trimester of pregnancy and elevated bile acids and/or transaminases. ICP is associated with an increased risk of adverse perinatal outcomes for the fetus and the later development of hepatobiliary disease for the mother. Bile acids should be monitored throughout pregnancy since fetal risk is increased at serum bile acids >40 µmol/l. Management of ICP consists of treatment with ursodeoxycholic acid, which reduces pruritus. Early elective delivery is common practice but should be performed on an individualized basis as long as strong evidence supporting this practice is lacking. Mothers should be followed-up for normalization of liver function tests 6-12 weeks after delivery. Future research in large-scale studies is needed to address the impact of ursodeoxycholic acid and early elective delivery on fetal outcome.

Clin Gastroenterol Hepatol 2016; 14:287-94.e1-2.

Abstract
BACKGROUND & AIMS Little is known in the United States about the epidemiology of liver diseases that develop only during (are unique to) pregnancy. We investigated the incidence of liver diseases unique to pregnancy in Olmsted County, Minnesota, and long-term maternal and fetal outcomes. METHODS We identified 247 women with liver diseases unique to pregnancy from 1996 through 2010 using the Rochester Epidemiology Project database. The crude incidence rate was calculated by the number of liver disease cases divided by 35,101 pregnancies. RESULTS Of pregnant women with liver diseases, 134 had preeclampsia with liver dysfunction, 72 had hemolysis-associated increased levels of liver enzymes and low-platelet (HELLP) syndrome, 26 had intrahepatic cholestasis of pregnancy, 14 had hyperemesis gravidarum with abnormal liver enzymes, and 1 had acute fatty liver of pregnancy. The crude incidence of liver diseases unique to pregnancy was 0.77%. Outcomes were worse among women with HELLP or preeclampsia than the other disorders--of women with HELLP, 70% had a premature delivery, 4% had abruptio placentae, 3% had acute kidney injury, and 3% had infant death. Of women with preeclampsia, 56.0% had a premature delivery, 4% had abruptio placentae, 3% had acute kidney injury, and 0.7% had infant death. After 7 median years of follow-up (range, 0-18 years), 14% of the women developed recurrent liver disease unique to pregnancy; the proportions were highest in women with initial hyperemesis gravidarum (36%) or intrahepatic cholestasis of pregnancy (35%). Women with preeclampsia were more likely to develop subsequent hepatobiliary diseases. CONCLUSIONS We found the incidence of liver disease unique to pregnancy in Olmsted County, Minnesota, to be lower than that reported from Europe or US tertiary referral centers. Maternal and fetal outcomes in Olmsted County were better than those reported from other studies, but fetal mortality was still high (0.7%-3.0%). Women with preeclampsia or HELLP are at higher risk for peripartum complications and subsequent development of comorbidities.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) is characterized by maternal pruritus, and elevated serum transaminases and bile acids. Genetic defects in at least 6 canalicular transporters have been found. Association studies stress the variability of genotypes, different penetrance, and influence of environmental factors. Serum autotaxin is a sensitive, specific, and robust diagnostic marker. Elevated maternal bile acids correlate with fetal complications. Long-term sequelae for mothers include the gallstone risk and chronic liver disease. There is an association between ICP and hepatitis C. Current treatment is ursodeoxycholic acid, owing to benefits on pruritus, liver function, safety, and decreased rates of adverse effects.

Abstract
Determining the optimal timing for induction of labor is critical in minimizing the risks to maternal and fetal health. While data are available to guide us in some clinical situations, such as hypertension and diabetes, many gaps in knowledge still exist in others, including cholestasis of pregnancy, fetal anomalies, and placental abruption. This review of the currently available literature assesses the risks and benefits of preterm and early term induction in a wide variety of maternal and fetal conditions.

Abstract
OBJECTIVE To describe perinatal outcomes of twin pregnancies complicated by intrahepatic cholestasis of pregnancy (ICP). METHODS We conducted a retrospective cohort study of women delivered at a large tertiary obstetric center in Shanghai, China from January 2006 to May 2014. Delivery data were abstracted from medical records of all twin gestations delivered at the hospital. RESULTS A total of 129/1922(6.7%) twin and 1190/92 273 singleton (1.3%) pregnancies were complicated by ICP. An increased risk of stillbirth among twin pregnancies was observed (3.9% and 0.8% in the ICP and non-ICP groups, respectively; aOR 5.75, 95% CI 2.00-16.6). Stillbirths with ICP and twins occurred between 33 and 35 weeks gestation compared to 36-38 weeks gestation among singletons. ICP in twins was also associated with an increased risk of preterm birth (<37 weeks) with an aOR of 4.17 (95% CI 2.47-7.04) and an aOR of 1.89 (95% CI 1.26-2.85) for delivery <35 weeks. Twin pregnancies complicated by ICP also had increased meconium staining of amniotic fluid and lower birth weight. CONCLUSIONS Twin pregnancies with ICP have significantly increased risks of adverse perinatal outcomes including stillbirth and preterm birth. Stillbirth occurs at an earlier gestational age in twin gestation compared to singletons, suggesting that earlier scheduled delivery should be considered in these women.

Severe intrahepatic cholestasis of pregnancy is a risk factor for preeclampsia in singleton and twin pregnancies. Am J Obstet Gynecol 2015; 213:395.e1-8. [PMID: 25979617 DOI: 10.1016/j.ajog.2015.05.011] [Citation(s) in RCA: 41] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2014] [Revised: 02/27/2015] [Accepted: 05/07/2015] [Indexed: 12/20/2022]
Abstract
OBJECTIVE Intrahepatic cholestasis of pregnancy (ICP) is known to be associated with fetal complications. It recently was suggested to be associated possibly with preeclampsia (PET) as well. The objective of this study was to investigate that possibility. STUDY DESIGN The study group included 78 women (54 singleton and 24 twin pregnancies) who had been diagnosed with ICP based on clinical presentation, elevated liver enzymes, and elevated total bile acids (>10 μmol/L). Disease severity was based on total bile acids levels as being severe (>40 μmol/L), moderate (20-40 μmol/L), or mild (10-20 μmol/L). The course of disease was reviewed carefully in each case. The control groups were comprised of apparently healthy women with singleton (n = 200) and twin (n = 100) pregnancies that were drawn randomly from a computerized registry of all the deliveries in our institution during the study period. RESULTS The total incidence of PET was significantly higher for the patients with ICP who had singleton and twin pregnancies compared with the control groups (singletons: 7.4% vs 1.5%; P < .05; twins: 33.3% vs 6.2%; P < .05, respectively). The incidence of severe PET was also significantly higher in both singleton (11-fold) and twin (8-fold) pregnancies compared with control subjects. Severe ICP, but not mild ICP, was a major risk factor for PET among women with either singleton or twin pregnancies. The timing of the initial presentation of ICP had no effect on PET incidence rates. Preeclampsia occurred usually 2-4 weeks after the diagnosis of ICP, and proteinuria preceded elevated blood pressure in all cases. Moreover, the total bile acid levels among 33 women who were diagnosed as having PET, but not ICP, were within normal range. CONCLUSION ICP increases the incidence of PET; severe disease was a major risk factor for preeclampsia. Therefore, we strongly suggest including routine evaluation for preeclampsia in the treatment of women with moderate and severe ICP.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) is a reversible pregnancy-specific cholestatic condition characterized by pruritus, elevated liver enzymes, and increased serum bile acids. It commences usually in the late second or third trimester, and quickly resolves after delivery. The incidence is higher in South American and Scandinavian countries (9.2%-15.6% and 1.5%, respectively) than in Europe (0.1%-0.2%). The etiology is multifactorial where genetic, endocrine, and environmental factors interact. Maternal outcome is usually benign, whereas fetal complications such as preterm labor, meconium staining, fetal distress, and sudden intrauterine fetal demise not infrequently lead to considerable perinatal morbidity and mortality. Ursodeoxycholic acid is shown to be the most efficient therapeutic agent with proven safety and efficacy. Management of ICP consists of careful monitoring of maternal hepatic function tests and serum bile acid levels in addition to the assessment of fetal well-being and timely delivery after completion of fetal pulmonary maturity. This review focuses on the current concepts about ICP based on recent literature data and presents an update regarding the diagnosis and management of this challenging issue.
