Abstract
OBJECTIVE Intrahepatic cholestasis of pregnancy (ICP) can cause adverse perinatal outcomes. Previous studies have demonstrated that the placenta of an ICP pregnancy differs in morphology and gene expression from the placenta of a normal pregnancy. To date, however, the genetic mechanism by which ICP affects the placenta is poorly understood. Therefore, the aim of this study was to investigate the differences in main cell types, gene signatures, cell ratio, and functional changes in the placenta between ICP and normal pregnancy. METHODS Single-cell RNA sequencing (scRNA-seq) technology was used to detect the gene expression of all cells at the placental maternal-fetal interface. Two individuals were analyzed - one with ICP and one without ICP. The classification of cell types was determined by a graph-based clustering algorithm. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed using the R software phyper () function and DAVID website. The differentially expressed genes (DEGs) encoding transcription factors (TFs) were identified using getorf and DIAMOND software. RESULTS We identified 14 cell types and 22 distinct cell subtypes that showed unique functional properties. Additionally, we found differences in the proportions of fibroblasts 1, helper T (Th) cells, extravillous trophoblasts, and villous cytotrophoblasts, and we observed heterogeneity of gene expression between ICP and control placentas. Furthermore, we identified 263 DEGs that belonged to TF families, including zf-C2H2, HMGI/HMGY, and Homeobox. In addition, 28 imprinted genes were preferentially expressed in specific cell types, such as PEG3 and PEG10 in trophoblasts as well as DLK1 and DIO3 in fibroblasts. CONCLUSIONS Our results revealed the differences in cell-type ratios, gene expression, and functional changes between ICP and normal placentas, and heterogeneity was found among cell subgroups. Hence, the imbalance of various cell types affects placental activity to varying degrees, indicating the complexity of the cell networks that form the placental tissue system, and this alteration of placental function is associated with adverse events in the perinatal period.

The severity of intrahepatic cholestasis during pregnancy increases risks of adverse outcomes beyond stillbirth: evidence from 15,826 patients. BMC Pregnancy Childbirth 2024; 24:476. [PMID: 38997626 DOI: 10.1186/s12884-024-06645-2] [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: 03/13/2024] [Accepted: 06/17/2024] [Indexed: 07/14/2024] Open
Abstract
BACKGROUND What kinds of fetal adverse outcomes beyond stillbirth directly correlate to the severity of intrahepatic cholestasis during pregnancy (ICP) remained tangled. Herein, we conducted a retrospective cohort study and a dose-response meta-analysis to speculate the association between the severity of ICP and its adverse outcomes. METHODS We retrospectively collected a cohort of ICP patients from electronic records from Guangzhou Women and Children's Medical Center between Jan 1st, 2018, and Dec 31st, 2022. Also, we searched PubMed, Cochrane, Embase, Scopus, and Web of Science to extract prior studies for meta-analysis. The Kruskal-Wallis test, a one-way or two-way variants analysis (ANOVA), and multi-variant regression are utilized for cohort study. One stage model, restricted cubic spline analysis, and fixed-effect model are applied for dose-response meta-analysis. The data analysis was performed using the R programme. RESULTS Our cohort included 1,289 pregnant individuals, including 385 mild ICP cases, 601 low moderate ICP cases, 282 high moderate ICP cases, and 21 severe ICP cases. The high moderate bile acid levels were correlated to preterm birth [RR = 2.14, 95%CI 1.27 to 3.62), P < 0.01], and preterm premature rupture of membranes [RR = 0.34, 95%CI 0.19 to 0.62), P < 0.01]. We added our cases to cases reported by other studies included in the meta-analysis. There were 15,826 patients included in dose-response meta-analysis. The severity of ICP was associated with increased risks of stillbirth, spontaneous preterm birth, iatrogenic preterm birth, preterm birth, admission to neonatal intensive care unit, and meconium-stained fluid (P < 0.05). CONCLUSIONS Our study shows the correlation between the severity of ICP and the ascending risks of stillbirth, preterm birth, and meconium-stained fluid, providing new threshold TBA levels. PROSPERO REGISTRATION NUMBER CRD42023472634.

[PMID: 38938614 PMCID: PMC11210484 DOI: 10.7717/peerj.17613] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Accepted: 05/31/2024] [Indexed: 06/29/2024] Open
Abstract
Background To determine the association between lipid metabolism and intrahepatic cholestasis of pregnancy (ICP), and explore the value of maternal alanine aminotransferase/aspartate aminotransferase (ALT/AST) and high-density lipoprotein (HDL) in predicting adverse neonatal outcomes in women with ICP. Methods A total of 147 pregnant women with ICP admitted to The Fourth Hospital of Shijiazhuang and 120 normal pregnant women in the same period were selected in this study. The Mann-Whitney U test and Chi-square tests were used to compare the differences in clinical data. Multivariate logistic regression was used to analyze the relationship between ALT/AST and the occurrence of adverse pregnancy outcomes in patients with ICP. The combined predictive value of ALT/AST and HDL was determined by receiver operating characteristic (ROC) curve analysis. Results Among 147 women with ICP, 122 women had total bile acid (TBA) levels of 10-39.9 µmol/L, and 25 had TBA ≥ 40 µmol/L. There was significantly lower gestational age in patients with severe ICP than in those with mild and control groups (all p < 0.05), and the weight of newborns in the maternal ICP group was significantly lower than in the control group (p < 0.05). Increasing TBA levels was associated with higher AST, ALT, ALT/AST, and lower HDL level (all p < 0.05). Meanwhile, higher levels of ALT/AST was positively associated with neonatal hyperbilirubinemia [adjusted odds ratio (AOR) = 4.019, 95% CI [1.757-9.194, p = 0.001] and cardiac injury [AOR = 3.500, 95% CI [1.535-7.987], p = 0.003]. HDL was a significant protective factor for neonatal hyperbilirubinemia and cardiac injury [AOR = 0.315, 95% CI [0.126-0.788], p = 0.014; AOR = 0.134 (0.039-0.461), p = 0.001]. The area under the ROC curve (AUC) for prediction of neonatal hyperbilirubinemia by ALT/AST combined with HDL was 0.668 [95% CI [56.3-77.3%], p = 0.002], and the sensitivity and specificity were 47.1% and 84.0%, respectively. To predict neonatal cardiac injury, the AUC value was 0.668 [95% CI [56.4-77.1%], p = 0.002], with sensitivity and specificity were 41.2% and 87.1%, respectively. Conclusions The levels of higher ALT/AST and lower HDL were significantly associated with the risk of ICP-related adverse neonatal outcomes. Moreover, ALT/AST combined with HDL has moderate clinical value in predicting the adverse outcomes of neonatal hyperbilirubinemia and cardiac injury.

Abstract
BACKGROUND Intrahepatic cholestasis of pregnancy (ICP) is a serious liver conditions that negatively impacts obstetric and neonatal outcomes. Elevated levels of bile acid, particularly glycine conjugate, may compromise blood flow and cause functional hypoxia-ischemia. AIMS This meta-analysis aims to assess the association between ICP and key pregnancy outcomes including emergency caesarian sections (C-sections), preeclampsia, hemorrhage, preterm birth, small for gestational age, admission rate to neonatal intensive care union (NICU), gestational age, and stillbirth. MATERIALS AND METHODS Literature search across five databases (PubMed, Embase, Web of Science) was done to detect relevant studies published up until June 2023. Meta-analysis of the identified studies was done using a random-effects model, and the results presented as Odds ratio (OR). RESULTS A literature search identified 662 studies. Of them, 21 met the inclusion criteria. There was a significant association between ICP and odds of C-section (OR: 1.42, p <0.001), preeclampsia (OR: 2.64, p <0.001), NICU admission (OR: 2.1, p <0.001), and pre-term birth (OR: 2.64, p <0.001). ICP was not associated with postpartum hemmorhage (OR: 1.31, p = 0.13), small for gestational age (OR: 0.87, p = 0.07), stillbirth (OR: 1.49, p = 0.29). CONCLUSIONS Our results confirm the adverse effects of ICP on co-existing pregnancy complications, obstetric and neonatal outcomes. ICP in associated with severe complications including increased rates of preeclampsia, emergency C-sections, preterm births, l gestational periods and higher rates of NICU admissions. These results may assist healthcare professionals in formulating comprehensive care guidelines for expectant mothers and newborns.

Abstract
INTRODUCTION AND OBJECTIVES Intrahepatic cholestasis of pregnancy (ICP) is often accompanied by fetal and maternal complications. MATERIALS AND METHODS Retrospective review of the clinical course of women with ICP and their neonates treated at our medical center over a 10-year period. Special attention was paid to the maternal and neonatal response to 2 different modes of ursodeoxycholic acid (UDCA) administration. RESULTS Neonates of mothers with high total bile acid levels had a poorer composite neonatal outcome. Twenty-seven women who presented at an advanced stage of their pregnancies did not receive UDCA. UDCA was administered in 2 modes: either a full dose at admission (76 women) or a gradually increasing dose until the desired dosage was reached (25 women). The mean gestational age at delivery for the 94 neonates that were exposed to full UDCA dose was the lowest (36±2.3 weeks for the full dose, 37±1.4 weeks for the 30 neonates from the gradually increasing dose, 38±1.6 weeks for the 29 neonates from the no treatment group, p<0.001). The group of neonates that were exposed to full UDCA dose had the highest rate of unfavorable composite neonatal outcome (53% for full dose, 30% for gradually increasing dose, 24% for the no treatment group, p=0.006). CONCLUSIONS Compared to the administration of a full UDCA dose, the administration of a gradually increasing dose of UDCA may be associated with a greater gestational age at delivery and fewer events of unfavorable composite neonatal outcomes. These novel findings should be retested prospectively in a large cohort of patients.

Abstract
OBJECTIVE Intrahepatic cholestasis of pregnancy is associated with adverse pregnancy outcomes including intrauterine fetal demise, spontaneous preterm labor, and meconium-stained amniotic fluid. Studies have yet to determine if patients with a history of pregnancy complicated by cholestasis had an association with more severe adverse outcomes in a subsequent pregnancy complicated by cholestasis. STUDY DESIGN Retrospective cohort study of multiparous, singleton, nonanomalous live gestations complicated by cholestasis at Elmhurst Hospital Center from 2005 to 2019. We compared rates of adverse outcomes in multiparous pregnancies complicated by cholestasis with versus without prior cholestasis. Our primary outcome was rates of spontaneous preterm labor. Our secondary outcomes included rates of iatrogenic preterm birth, meconium-stained amniotic fluid, cesarean delivery for nonreassuring fetal heart tracing. Chi-square and multivariate regression tests were used to determine the strength of association. In all analyses, a p-value less than 0.05 and 95% confidence interval not crossing 1.00 indicated statistical significance. Mount Sinai Icahn School of Medicine Institutional Review Board approval was obtained for this project. RESULTS Of the 795 multiparous pregnancies complicated by cholestasis, 618 (77.7%) had no prior history of cholestasis and 177 (23.3%) had prior history of cholestasis. Multiparous pregnancies with history of cholestasis had higher rates of prior preterm birth, earlier gestational age at diagnosis and delivery, and were more likely to receive ursodeoxycholic acid therapy. Pregnancies with history of cholestasis were not associated with spontaneous preterm labor in subsequent pregnancies with cholestasis, but history of cholestasis was associated with iatrogenic preterm birth and neonatal intensive care unit (NICU) admission. After adjusting for confounders, the association with iatrogenic preterm birth and NICU admission were no longer statistically significant. There was no significant association between history of cholestasis and other adverse obstetric outcomes. CONCLUSION Findings suggests that history of prior cholestasis is not associated with worsening outcomes in subsequent pregnancies complicated by cholestasis. KEY POINTS · Prior cholestasis may not alter risk in subsequent pregnancies.. · Unclear relationship between cholestasis and hepatobiliary disease.. · Studies needed to develop cholestasis screening protocol..

Abstract
PURPOSE To evaluate the effect of intrahepatic cholestasis of pregnancy (ICP) with gestational diabetes mellitus (GDM) on perinatal outcomes and establish a prediction model of adverse perinatal outcomes in women with ICP. METHODS This multicenter retrospective cohort study included the clinical data of 2,178 pregnant women with ICP, including 1,788 women with ICP and 390 co-occurrence ICP and GDM. The data of all subjects were collected from hospital electronic medical records. Univariate and multivariate logistic regression analysis were used to compare the incidence of perinatal outcomes between ICP with GDM group and ICP alone group. RESULTS Baseline characteristics of the population revealed that maternal age (p < 0.001), pregestational weight (p = 0.01), pre-pregnancy BMI (p < 0.001), gestational weight gain (p < 0.001), assisted reproductive technology (ART) (p < 0.001), and total bile acid concentration (p = 0.024) may be risk factors for ICP with GDM. Furthermore, ICP with GDM demonstrated a higher association with both polyhydramnios (OR 2.66) and preterm labor (OR 1.67) compared to ICP alone. Further subgroup analysis based on the severity of ICP showed that elevated total bile acid concentrations were closely associated with an increased risk of preterm labour, meconium-stained amniotic fluid, and low birth weight in both ICP alone and ICP with GDM groups. ICP with GDM further worsened these outcomes, especially in women with severe ICP. The nomogram prediction model effectively predicted the occurrence of preterm labour in the ICP population. CONCLUSIONS ICP with GDM may result in more adverse pregnancy outcomes, which are associated with bile acid concentrations.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) is a hepatic disorder in pregnancy linked with adverse fetal outcomes, which primarily manifests in the late second and third trimesters of pregnancy. This review aims to recapitulate the existing evidence on factors that can predict detrimental perinatal outcomes in pregnant women diagnosed with intrahepatic cholestasis of pregnancy. We searched PubMed, Web of Science, Cochrane Library, Scopus, Medline, and Embase databases and selected studies related to predictors of fetal outcome in intrahepatic cholestasis of pregnancy. Studies of the articles showed that predictors of an adverse fetal outcome include in vitro fertilization (IVF) pregnancy, multifetal pregnancy, biochemical markers, gestational age of ICP onset, presence of comorbidities (preeclampsia and gestational diabetes mellitus), maternal history of ICP, and hepatobiliary disease.Intrahepatic cholestasis of pregnancy (ICP) complicates the pregnancy. Hence, early assessment of low-risk and high-risk groups will help to administer definite management protocols and strategies to prevent adverse neonatal outcomes. Further research should concentrate on the number of conditions/factors and the predictive power of different factors to determine the most reliable predictors and biomarkers that can predict adverse fetal outcomes and improve the assessment of risk in pregnancy complicated with ICP.

Abstract
BACKGROUND To explore the association between liver metabolism-related indicators in maternal serum and neonatal hyperbilirubinemia (NHB), and further investigate the predictive value of these indicators in NHB-related amino acid metabolism disorders. METHODS 51 NHB and 182 No-NHB newborns and their mothers who treated in the Fourth Hospital of Shijiazhuang from 2018 to 2022 were participated in the study. The differences in clinical data were compared by the Mann-Whitney U test and Chi-square test. Multivariate logistic regression was used to analyze the relationship between maternal serum indicators and the occurrence of NHB. The correlation analysis and risk factor assessment of maternal serum indicators with NHB-related amino acid metabolic disorders were performed using Spearman correlation analysis and multivariate logistic regression. RESULTS Compared to the non NHB group, the NHB group had higher maternal serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), ALT/AST, and total bile acid (TBA), while lower levels of serum albumin (ALB), total cholesterol (TC) and high-density lipoprotein (HDL). The levels of alanine (ALA), valine (VAL), ornithine (ORN), and proline (PRO) in the newborns were reduced in NHB group, while arginine (ARG) showed a tendency to be elevated. Multiple logistic regression analysis showed that maternal ALT, AST, ALT/AST, and TBA levels were all at higher risk with the development of NHB, whereas ALB, TC, and HDL levels were negatively associated with NHB development. Increasing maternal TBA level was associated with lower ALA (r=-0.167, p = 0.011), VAL (r=-0.214, p = 0.001), ORN (r=-0.196, p = 0.003), and PRO in the newborns (r=-0.131, p = 0.045). Maternal ALT level was negatively associated with ALA (r=-0.135, p = 0.039), VAL (r=-0.177, p = 0.007), ORN (r=-0.257, p < 0.001), while ALT/AST was positively correlated with ARG (r = 0.133, p = 0.013). After adjustment for confounding factors, maternal serum TBA and ALT were the independent risk factor for neonatal ORN metabolic disorders [(adjusted odds ratio (AOR) = 0.379, 95%CI = 0.188-0.762, p = 0.006), (AOR = 0.441, 95%CI = 0.211-0.922, p = 0.030)]. Maternal ALT level was an independent risk factor for neonatal VAL metabolic disorders (AOR = 0.454, 95%CI = 0.218-0.949, p = 0.036). CONCLUSIONS The levels of high TBA, ALT, AST, and low HDL, TC of maternal were associated with the risk of NHB. Maternal TBA and ALT levels were independent risk factors for NHB-related amino acid disturbances which have value as predictive makers.

A nomogram for predicting the risk of preeclampsia in women with intrahepatic cholestasis of pregnancy based on prenatal monitoring time: a multicenter retrospective cohort study. J Hypertens 2024; 42:143-152. [PMID: 37737865 PMCID: PMC10712991 DOI: 10.1097/hjh.0000000000003577] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Revised: 08/03/2023] [Accepted: 08/25/2023] [Indexed: 09/23/2023]
Abstract
BACKGROUND AND AIMS Intrahepatic cholestasis of pregnancy (ICP) is a special liver disease during pregnancy, characterized by abnormal bile acid metabolism. However, there is no consensus on how to group women with ICP based on the time of diagnosis worldwide. This study aimed to adopt a new grouping model of women with ICP, and the time from diagnosis to delivery was defined as the monitoring period. METHODS This retrospective real-world data study was conducted across multiple centers and included 3172 women with ICP. The study first evaluated the significant difference in medication and nonmedication during different monitoring times. The least absolute shrinkage and selection operator (LASSO) model was then used to screen nine risk factors based on the predictors. The model's discrimination, clinical usefulness, and calibration were assessed using the area under the receiver operating characteristic (ROC) curve, decision curve, and calibration analysis. RESULTS The incidence of preeclampsia risk in ICP patients without drug intervention increased with the extension of the monitoring period. However, the risk of preeclampsia decreased in ICP patients treated with ursodeoxycholic acid. A predictive nomogram and risk score model was developed based on nine risk factors. The area under the ROC curve of the nomogram was 0.765 [95% confidence interval (CI): 0.724-0.807] and 0.812 (95% CI: 0.736-0.889) for the validation cohort. CONCLUSIONS This study found that a longer ICP monitoring period could lead to adverse pregnancy outcomes in the absence of drug intervention, especially preeclampsia. A predictive nomogram and risk score model was developed to better manage ICP patients, maintain pregnancy to term delivery, and minimize the risk of severe adverse maternal and fetal outcomes.

Abstract
Intrahepatic cholestasis during pregnancy is associated with a higher risk of prenatal and maternal complications. There are several new publications and guidelines on the detection and thresholds of intrahepatic cholestasis during pregnancy. However, the genetic background of this disease has rarely been investigated. This is a comprehensive review of the roles of genes in intrahepatic cholestasis during pregnancy.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) is a common liver disorder that generally occurs during the second or third trimester of pregnancy. It rarely causes any harm to the mother; however, it can result in short- and long-term complications in the offspring. Therefore, it is crucial to diagnose and treat this condition to avoid poor pregnancy outcomes. The identification of novel markers with potential diagnostic, prognostic, and therapeutic utility in ICP has gained attention. Noncoding RNAs (ncRNAs), including microRNA, long noncoding RNA, and circular RNA, are a type of transcripts that are not translated into proteins. They possess vital biological functions, including transcriptional and translational regulation and DNA, RNA, and protein interactions. The pathogenesis of ICP is related to the aberrant expression of several circulating or placenta-related ncRNAs. In this review, we summarized all recent findings on ncRNAs and ICP and outlined the concepts that form the basis for the early diagnosis and targeted treatment of ICP.

Abstract
Liver disease is not uncommon during pregnancy and is associated with increased maternal and fetal/neonatal morbidity and mortality. Physiological changes during pregnancy, including a hyperestrogenic state, increase in circulating plasma volume and/or reduction in splanchnic vascular resistance, and hemostatic imbalance, may mimic or worsen liver disease. For the clinician, it is important to distinguish among the first presentation or exacerbation of chronic liver disease, acute liver disease non-specific to pregnancy, and pregnancy-specific liver disease. This last group classically includes conditions such as hyperemesis gravidarum, intrahepatic cholestasis of pregnancy, liver disorders associated with the pre-eclampsia spectrum, and an acute fatty liver of pregnancy. All of these disorders often share pathophysiological mechanisms, symptoms, and laboratory findings (such as elevated liver enzymes), but a prompt and correct diagnosis is fundamental to guide obstetric conduct, reduce morbidity and mortality, and inform upon the risk of recurrence or development of other chronic diseases later on in life. Finally, the cause of elevated liver enzymes during pregnancy is unclear in up to 30-40% of the cases, and yet, little is known on the causes and mechanisms underlying these alterations, or whether these findings are associated with worse maternal/fetal outcomes. In this narrative review, we aimed to summarize pragmatically the diagnostic work-up and the management of subjects with elevated liver enzymes during pregnancy.

Abstract
BACKGROUND Velamentous cord insertion (VCI) and marginal cord insertion (MCI) are well-known risk factors for adverse perinatal outcomes in singleton pregnancies. However, the potential links between VCI or MCI and perinatal outcomes in twin pregnancies have yet to be systematically evaluated. This study aimed to investigate the relationships between VCI or MCI and perinatal outcomes in twin pregnancies. METHODS This retrospective single-center cohort study included women with twin pregnancies who gave birth in a tertiary hospital in Southwest, China between January 2017 and December 2022. VCI and MCI were identified by abdominal ultrasound and confirmed after placental delivery. Logistic regression, multinomial logit regression and generalized estimation equation models were used to evaluate the association between VCI or MCI and perinatal outcomes. RESULTS A total of 3682 twin pregnancies were included, including 100 (2.7%) pregnancies with VCI and 149 (4.0%) pregnancies with MCI. Compared to pregnancies with normal cord insertion, both monochorionic and dichorionic pregnancies with VCI were associated with an increased risk of preterm delivery 32-34 weeks (aRRR 2.94, 95% CI 1.03-8.39; aRRR 2.55, 95% CI 1.19-5.46, respectively), while pregnancies with MCI were not associated with preterm delivery. VCI was associated with a higher incidence of placental previa (aOR 6.36, 95% CI 1.92-21.04) in monochorionic pregnancies and placental accreta (aOR 1.85, 95% CI 1.06-3.23) in dichorionic pregnancies. MCI was associated with an increased risk of preeclampsia (aOR 3.07, 95% CI 1.49-6.32), intertwin birthweight discordance ≥ 20% (aOR 2.40, 95% CI 1.08-5.60) and selective fetal growth restriction (aOR 2.46, 95% CI 1.08-5.60) in monochorionic pregnancies and small-for-gestational age neonates (aOR 1.97, 95% CI 1.24-3.14) in dichorionic pregnancies. CONCLUSIONS VCI was associated with an increased risk of preterm delivery in twin pregnancies irrespective of chorionicity, whereas MCI was associated with an increased preeclampsia risk, significant intertwin birthweight discordance in monochorionic pregnancies and small-for-gestational age neonates in dichorionic pregnancies.

Abstract
Recent case reports suggest an association between severe intrahepatic cholestasis of pregnancy and fat-soluble vitamin deficiencies, including vitamin K deficiency. Screening for coagulopathy and fat-soluble vitamin deficiency has been proposed as a possible strategy to identify pregnancies at additional risk of adverse outcomes and allow for earlier risk-reducing iatrogenic preterm delivery. This report highlights a case of routine screening that resulted in the detection of subclinical coagulopathy that allowed for earlier intervention and delivery of a healthy neonate at 34 weeks of gestation. Further prospective studies are needed to determine the clinical use of routine screening in detecting coagulopathy and fat-soluble vitamin deficiency in cases of severe cholestasis.

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.

Abstract
Background To determine the risk factors for cesarean section (CS) and adverse fetal outcomes (AFOs) in patients with intrahepatic cholestasis of pregnancy (ICP) based on the severity of maternal hypercholanemia. Methods A hospital-based retrospective cohort study was performed between January 1, 2015, and December 31, 2019. A total of 227 nulliparous women with a singleton fetus complicated by ICP were included. The patients were divided into two groups according to the levels of total bile acids, that is, mild (10 μmol/L < total bile acids < 40 μmol/L) and severe (≥40 μmol/L). The patients' clinical characteristics and fetal outcomes were assessed. Results Among the 227 eligible women, 177 (78.0%) were allocated to the mild group and 50 (22.0%) were in the severe group. Women with severe ICP also had a significantly higher incidence of planned and unplanned CS compared with mild ICP subjects (52.0% vs. 23.7% and 22.0% vs. 6.8%, respectively; p < 0.001). The indications for CS showed that fetal intolerance (65.4% vs. 14.3%) was higher in severe ICP compared with mild ICP (p < 0.001). Severe ICP was associated with an increased risk of preterm delivery (p < 0.001), low birthweight (p = 0.001), and neonatal intensive care unit (NICU) admission (p < 0.001). Women with severe ICP (OR 6.397, 95%CI 3.041-13.455, p < 0.001) or preeclampsia (OR 12.434, 95%CI 5.166-29.928, p < 0.001) had increased risks of AFOs compared to controls. Conclusions Severe ICP and preeclampsia are associated with a higher incidence of AFOs.

Abstract
Hereditary cholestatic liver disease caused by a class of autosomal gene mutations results in jaundice, which involves the abnormality of the synthesis, secretion, and other disorders of bile acids metabolism. Due to the existence of a variety of gene mutations, the clinical manifestations of children are also diverse. There is no unified standard for diagnosis and single detection method, which seriously hinders the development of clinical treatment. Therefore, the mutated genes of hereditary intrahepatic cholestasis were systematically described in this review.

Abstract
Objective To investigate the levels of serum fetuin B in healthy pregnant women and women with intrahepatic cholestasis of pregnancy (IHCP) and their association with pregnancy outcomes. Materials and Methods This was a prospective case-control study, we included sixty singleton pregnant women with IHCP and sixty healthy-matched pregnant women in their third trimester. The serum fetuin B levels of these patients were analyzed. All the patients were followed up prospectively until delivery and data related to maternal, perinatal, and neonatal outcomes were obtained. Results Total bile acid levels and liver function tests were significantly higher in the IHCP group than in the control group (p<0.0001 and <0.0001, respectively). The serum fetuin B concentrations were higher in the IHCP group than in the control group, without any significant group difference (p=0.105). Preterm delivery, iatrogenic preterm delivery, and birth weight ≤2.500 gm are only significantly associated with serum fetuin B levels respectively (p<0.05). The diagnostic performance of serum bile acids [area under the curve (AUC)=0.998] was significantly better than that of fetuin B (AUC=0.586) (DeLong's test p≤0.001). Conclusion We neither noted a significant difference between the IHCP and control groups concerning the serum fetuin B levels nor could we correlate its levels with adverse maternal and perinatal outcomes except with birth weight, thereby serum fetuin B was not an effective marker for use in shedding light on the pathophysiology of IHCP.

Abstract
This study reviewed the literature regarding the diagnosis, antepartum surveillance, and timing of delivery of pregnancies complicated by intrahepatic cholestasis of pregnancy, comparing the guidelines published by the Society for Maternal-Fetal Medicine in February 2021 and those published by the Royal College of Obstetricians and Gynaecologists in the United Kingdom in June 2022. Several key differences exist in the clinical guidelines between the 2 organizations. With regard to the diagnosis of intrahepatic cholestasis of pregnancy, the Society for Maternal-Fetal Medicine considers any elevation in bile acids above the upper limit of normal in the setting of maternal pruritus diagnostic of intrahepatic cholestasis of pregnancy, whereas the Royal College of Obstetricians and Gynaecologists requires a pregnancy-specific elevated bile acid level of ≥19 mmol/L for diagnosis. Regarding the treatment of intrahepatic cholestasis of pregnancy, the Society for Maternal-Fetal Medicine recommends ursodeoxycholic acid as the first-line treatment of maternal symptoms. In contrast, the Royal College of Obstetricians and Gynaecologists specifically recommends against the routine use of ursodeoxycholic acid for intrahepatic cholestasis of pregnancy because of a lack of evidence regarding both maternal and fetal benefit. The Society for Maternal-Fetal Medicine recommends fetal surveillance at a gestational age when abnormal fetal testing would result in delivery being performed, whereas the Royal College of Obstetricians and Gynaecologists does not recommend any fetal testing beyond fetal kick count assessment. The Society for Maternal-Fetal Medicine recommends delivery at 36 to 39 weeks' gestation for intrahepatic cholestasis of pregnancy with bile acids <100 mmol/L and delivery at 36 weeks for bile acid levels >100 mmol/L. The Royal College of Obstetricians and Gynaecologists recommends serial assessment of bile acids with delivery timing stratified between 35- and 40-weeks' gestation according to bile acid levels.

Abstract
This study aims to evaluate cardiac function in cases of intrahepatic cholestasis of pregnancy (ICP) and compare results with those from healthy controls using the fetal left ventricular modified myocardial performance index (LMPI) and E-wave/A-wave peak velocities (E/A ratio). Moreover, the association between LMPI values, total bile acid (TBA) levels, fetal Doppler measurements, and adverse neonatal outcomes was evaluated. A prospective cross-sectional study of 120 pregnant women was conducted, with 60 having ICP and the other 60 serving as controls. Doppler ultrasound and two-dimensional gray-scale fetal echocardiography were used to calculate the LMPI values and E/A ratios, respectively. The association between LMPI values and TBA levels, fetal Doppler measurements, and adverse neonatal outcomes was evaluated. Fetal LMPI values were significantly higher in the ICP group than in the control group (0.54 ± 0.54 vs. 0.44 ± 0.03; p < 0.001), but the E/A ratio was similar in both groups (0.69 ± 0.10 vs. 0.66 ± 0.14; p = 0.203). TBA levels were positively and significantly correlated with LMPI values (r = 0.546, p < 0.01); however, no significant correlation was found between umbilical arterial pulsatility index values and LMPI values (r = 0.071, p > 0.01). LMPI values were not associated with adverse neonatal outcomes in ICP cases. Fetal cardiac function (LMPI) is associated with increased bile acid levels in ICP. However, because it was not associated with adverse neonatal outcomes in ICP cases, the clinical significance of this finding is unclear. Further studies are required to evaluate the implications of increased LMPI.

Abstract
BACKGROUND Intrahepatic cholestasis of pregnancy (ICP) is the most common pregnancy-related liver disorder and may cause adverse perinatal outcomes. This large cross-sectional retrospective study aimed to evaluate the prevalence and related risk factors of ICP and determine the adverse perinatal outcomes. METHODS This large cohort study from 1 January 2018 to 31 December 2019, included 39,742 eligible pregnant women. Data were extracted from the institutional electronic medical record database and analyzed using univariate and multivariate logistic regression models to determine the risk factors and adverse perinatal outcomes of ICP. RESULTS The overall prevalence of ICP was 3.81%. It was significantly higher in hepatitis B surface antigen (HBsAg) positive than negative women in all age groups, and in women with pre-pregnancy BMI underweight and obesity aged <25 years and ≥35 years than the other age groups. Multivariate logistic regression models showed an increased risk of ICP associated with maternal age <25 years and ≥35 years, pre-pregnancy underweight and obesity, HBsAg positive status, twin pregnancies, low maternal education, inadequate gestational weight gain, multiparous, in vitro fertilization, caesarean section history and the number of abortions ≥2. The presence of ICP was associated with increased risk of maternal outcomes of caesarean section and preterm birth, and neonatal outcomes of low birth weight and neonatal unit admission in singleton and twin pregnancies. CONCLUSION This study identified the prevalence, possible risk factors, and associated adverse perinatal outcomes of ICP, which provides useful information for clinicians to identify, counsel, and provide timely management for women at risk.KEY MESSAGESMaternal age <25 and ≥35, pre-pregnancy BMI underweight and obesity, hepatitis B surface antigen-positive status, twin pregnancies, low maternal education, inadequate gestational weight gain, multiparous, in vitro fertilization, caesarean section history and the number of abortions ≥2 are associated with an increased risk of ICP.Further, pregnancies with ICP are associated with an increased risk of maternal outcomes of caesarean section and preterm birth and neonatal outcomes of low birth weight and neonatal unit admission in singleton and twin pregnancies.

Abstract
Background Intrahepatic cholestasis of pregnancy (ICP) is a complex liver disease with varying incidence worldwide. We compared ICP incidence and pregnancy outcomes with outcomes for normal pregnant controls. Methods We conducted a retrospective data analysis of perinatal registry data for the years 2011 and 2017 to compare the following outcome measures: stillbirths, labour induction, gestational diabetes, pre-eclampsia, antepartum haemorrhage, postpartum haemorrhage, preterm births, low Apgar score, acute neonatal respiratory morbidity, meconium aspiration and in-hospital neonatal death. Results The incidence of ICP was 8 per 1000 births from a total 31,493 singleton births with more cases in 2017 than in 2011. Women with ICP were almost six times more likely to have labour induced including significantly more moderate preterm births (defined as between 32 weeks and 36 weeks and 6 days of gestation)) seen more in 2011 than in 2017. Conclusion Women with ICP showed higher incidence of moderate preterm birth and induced labour but favourable maternal and neonatal outcomes.

Abstract
BACKGROUND Intrahepatic cholestasis of pregnancy is associated with a significant risk of stillbirth, which contributes to variation in clinical management. Recent Society for Maternal-Fetal Medicine guidance recommends delivery at 36 weeks of gestation for patients with serum bile acid levels of >100 μmol/L, consideration for delivery between 36 and 39 weeks of gestation stratified by bile acid level, and against preterm delivery for those with clinical features of cholestasis without bile acid elevation. OBJECTIVE This study aimed to investigate institutional practices before the publication of the new delivery timing recommendations to establish the maternal and neonatal effects of late preterm, early-term, and term deliveries in the setting of cholestasis. STUDY DESIGN This study examined maternal and neonatal outcomes of 441 patients affected by cholestasis delivering 484 neonates in a 4-hospital system over a 30-month period. Logistic and linear regression analyses were performed to assess neonatal outcomes concerning peak serum bile acid levels at various gestational ages controlling for maternal comorbidities, multiple pregnancies, and neonatal birthweight. RESULTS With the clinical flexibility afforded by the new guidelines, pregnancy prolongation to term may have been achieved in 91 patients (21%), and 286 patients (74%) with bile acid elevation could have delivered at a later gestational age. Preterm deliveries of patients with bile acid levels of >10 μmol/L were associated with higher rates of neonatal intensive care unit admission and adverse neonatal outcomes than early-term deliveries. CONCLUSION Study data suggested an opportunity for education and practice change to reflect current Society for Maternal-Fetal Medicine guidelines in efforts to reduce potential neonatal morbidities associated with late preterm deliveries among pregnancies affected by cholestasis.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) is the commonest among the specific dermatoses of pregnancy. The disease is characterised by intense pruritus and specifically by elevated bile acid levels and owing to the rarity of data published in this context, the disease carries a great challenge in both diagnosis and management. The disease is associated with significant maternal as well as perinatal adverse effects, hence, this article aims at improving the knowledge of the women's health carers with the up-to-date and evidence-based, whenever possible, recommendations while managing patients with ICP.

Abstract
BACKGROUND Intrahepatic cholestasis of pregnancy is associated with adverse pregnancy outcomes, including sudden fetal cardiac arrhythmias, resulting in stillbirth. This association has been correlated with the total bile acid levels, which are a marker for disease severity. Studies are yet to determine if intrahepatic cholestasis of pregnancy severity is also associated with increased rates of other adverse neonatal outcomes. OBJECTIVE This study aimed to determine whether pregnancies complicated by intrahepatic cholestasis of pregnancy show a bile acid severity-based relationship with other adverse obstetrical outcomes beyond stillbirth alone. STUDY DESIGN This was a retrospective cohort study of singleton, nonanomalous gestations complicated by intrahepatic cholestasis of pregnancy at the Elmhurst Hospital Center from 2005 to 2019. Severity was defined by the peak total bile acid levels (μmol/L): mild (10-19), low moderate (20-39), high moderate (40-99), and severe (>100). We examined the rates of spontaneous preterm labor, fetal growth restriction, preterm prelabor rupture of membranes, iatrogenic preterm birth, meconium-stained amniotic fluid, cesarean delivery for nonreassuring fetal heart tracing, umbilical artery pH, neonatal intensive care unit admission, and neonatal birthweight. The chi-square, Fisher exact, Student t, Mann-Whitney, and multivariate regression tests were used to determine the association of intrahepatic cholestasis of pregnancy severity and adverse neonatal outcomes. In all analyses, mild severity was used as the base comparator. A P value of <.05 and 95% confidence interval not crossing 1.00 indicated statistical significance. RESULTS Of the 1202 pregnancies complicated by intrahepatic cholestasis of pregnancy, 306 (25.5%) were mild, 449 were low moderate (37.4%), 327 were high moderate (27.2%), and 120 were severe (10.0%). After adjusting for confounders, progressive intrahepatic cholestasis of pregnancy severity was associated with an increased risk of spontaneous preterm labor (low moderate adjusted odds ratio, 1.60; 95% confidence interval, 0.76-3.38; high moderate adjusted odds ratio, 3.49; 95% confidence interval, 1.69-7.22; severe adjusted odds ratio, 6.58; 95% confidence interval, 2.97-14.55), iatrogenic preterm birth (low moderate adjusted odds ratio, 1.54; 95% confidence interval, 0.95-2.52; high moderate adjusted odds ratio, 3.11; 95% confidence interval, 1.91-5.06; severe adjusted odds ratio, 4.94; 95% confidence interval, 2.81-8.71), and meconium-stained amniotic fluid (low moderate adjusted odds ratio, 1.33; 95% confidence interval, 0.75-2.36; high moderate adjusted odds ratio, 2.63; 95% confidence interval, 1.48-4.65; severe adjusted odds ratio, 3.91; 95% confidence interval, 1.98-7.69). There was no significant association between intrahepatic cholestasis of pregnancy severity and other adverse outcomes. CONCLUSION The findings suggest that intrahepatic cholestasis of pregnancy disease severity is associated with an increased risk of spontaneous preterm labor, iatrogenic preterm birth, and meconium-stained amniotic fluid. These findings provide valuable insight toward patient anticipatory counseling.

Arch Gynecol Obstet 2022:10.1007/s00404-022-06754-3.

Abstract
Abstract
Purpose
Intrahepatic cholestasis of pregnancy (ICP) is associated with adverse fetal and neonatal outcome. Evidence for improvement by obstetric management is sparse. Common international guidelines recommend induction of labor before term, however, they differ in recommendations of monitoring the disease and time point of active management. So far, an official guideline for treatment and management of ICP in Germany does not exist. This study aims to compile common practice and policy in obstetric management of ICP in German maternity units. The objective is to gather obstetricians’ opinion on management of ICP, and to estimate the need for standardization of current practice in Germany on the background of existing evidence.
Methods
A questionnaire focusing on indications for interventions was developed including fourteen multiple-choice questions comprising the areas of diagnostic criteria, laboratory testing, fetal monitoring, treatment, and delivery timing. The survey was sent to 699 maternity clinics and was distributed to participants of the annual congress hosted by the German society of perinatal medicine (DGPM). Collected data were summarized and evaluated in relation to available evidence and existing guidelines. Descriptive statistics and Fisher's exact test were used.
Results
334 completed questionnaires returned corresponding to a response rate of 48.1%. Coinciding with existing international guidelines, 48.8% of the participants acknowledge bile acid concentrations above 10 µmol/L to be indicative of ICP. 85.0% of obstetricians recommend antenatal testing with cardiotocography, exceeding common standards of maternity policy guidelines; 50.3% execute active management in ICP-affected pregnancies as they generally recommend a delivery between 37 + 0 and 38 + 6 weeks of gestation. Although recent studies evinced a risk of stillbirth in ICP-affected pregnancies not until a bile acid concentration of > 100 µmol/L, 22.2% of the respondents recommend delivery before 37 + 0 weeks of gestation due to raised bile acids of 40–99 µmol/L.
Conclusions
Opinions on the management of ICP in German maternity units differ widely and partly deviate by large from international standards. Reasons for this may be the lack of a national guideline and the low awareness due to the rarity of the disease on the one hand and the very slow dynamics in evidence generation and thus the uncertainty about the actual risks and optimal management on the other. The present data highlight the need for further research and clinical guidelines to standardize and optimize treatment based on the best available evidence.

Abstract
Background: Intrahepatic cholestasis of pregnancy (ICP) is associated with a high incidence of fetal morbidity and mortality. Therefore, revealing the mechanisms involved in ICP and its association with fetal complications is very important. Methods: Here, we used a whole-exome sequencing (WES) approach to detect novel mutations of organic anion transporting polypeptide (OTAP) genes, ATP-binding cassette transporter (ABC) genes, and receptor genes associated with ICP in 249 individuals and 1,029 local control individuals. Two available tools, SIFT and PolyPhen-2, were used to predict protein damage. Protein structuremodeling and comparison between the reference and modified protein structures were conducted by SWISS-MODEL and Chimera 1.14rc software, respectively. Results: A total of 5,583 mutations were identified in 82 genes related to bile acid transporters and receptors, of which 62 were novel mutations. These novel mutations were absent in the 1,029 control individuals and three databases, including the 1,000 Genome Project (1000G_ALL), Exome Aggregation Consortium (ExAC), and Single-Nucleotide Polymorphism Database (dbSNP). We classified the 62 novel loci into two groups (damaging and probably damaging) according to the results of SIFT and PolyPhen-2. Out of the 62 novel mutations, 24 were detected in the damaging group. Of these, five novel possibly pathogenic variants were identified that were located in known functional genes, including ABCB4 (Ile377Asn), ABCB11 (Ala588Pro), ABCC2 (Ile681Lys and Met688Thr), and NR1H4 (Tyr149Ter). Moreover, compared to the wild-type protein structure, ABCC2 Ile681Lys and Met688Thr protein structures showed a slight change in the chemical bond lengths of ATP-ligand binding amino acid side chains. The combined 32 clinical data points indicate that the mutation group had a significantly (p = 0.04) lower level of Cl ions than the wild-type group. Particularly, patients with the 24 novel mutations had higher average values of alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), total bile acids (TBA), high-density lipoprotein (HDL), and low-density lipoprotein (LDL) than patients with the 38 novel mutations in the probably damaging group and the local control individuals. Conclusion: The present study provides new insights into the genetic architecture of ICP involving these novel mutations.

Abstract
Labor induction is one of the most common procedures performed during childbirth, on average in 20−30% of all pregnant women. The aim of this paper was to perform a retrospective analysis of the factors influencing the induction of childbirth. The data provide population-based evidence for Poland (Masovian Voivodeship). The electronic patient records of a hospital in Warsaw were used to create an anonymous retrospective database of all deliveries from 2015 to 2020. The study included an analysis of two groups of patients. The study group consisted of patients with labor induction—4350 cases, and the control group of patients with spontaneous contractions—20,345. The factors influencing the lower frequency of labor induction in the study group were previous cesarean section (OR = 0.73, 95% CI: 0.64−0.84, p < 0.05) and a higher number of deliveries (OR = 0.74, 95% CI: 0.68−0.80, p < 0.05). It is necessary to conduct further research about obstetric procedures used during childbirth, such as induction of childbirth, to reduce the risk of complications and improve the perinatal care of the mother and the neonate.

Circulatory Metabolomics Reveals the Association of the Metabolites With Clinical Features in the Patients With Intrahepatic Cholestasis of Pregnancy. Front Physiol 2022; 13:848508.

Abstract
Objective: Intrahepatic cholestasis of pregnancy (ICP) is associated with an increased risk of adverse pregnancy to the mother and fetus. As yet, the metabolic profiles and the association of the clinical features remain obscure. Methods: Fifty-seven healthy pregnant women and 52 patients with ICP were recruited in this study. Plasma samples were collected from pregnancies who received prenatal care between 30 and 36 weeks. Untargeted metabolomics to portray the metabolic profiles were performed by LC/MS. Multivariate combined with the univariate analysis was performed to screen out differential metabolites between the ICP and control groups. A de-biased sparse partial correlation (DSPC) network analysis of differential metabolites was conducted to explore the potential mutual regulation among metabolites on the basis of de-sparsified graphical lasso modeling. The pathway analysis was carried out using MetaboAnalyst. Linear regression and Pearson correlation analysis was applied to analyze correlations of bile acid levels, metabolites, newborn weights, and pregnancy outcomes in ICP patients. Results: Conspicuous metabolic changes and choreographed metabolic profiles were disclosed: 125 annotated metabolites and 18 metabolic pathways were disturbed in ICP patients. DSPC networks indicated dense interactions among amino acids and their derivatives, bile acids, carbohydrates, and organic acids. The levels of total bile acid (TBA) were increased in ICP patients with meconium-stained amniotic fluid (MSAF) compared with those without MSAF. An abnormal tryptophan metabolism, elevated long chain saturated fatty acids and estrone sulfate levels, and a low-antioxidant capacity were relevant to increased bile acid levels. Newborn weights were significantly associated with the levels of bile acids and some metabolites of amino acids. Conclusion: Our study revealed the metabolomic profiles in circulation and the correlation of the metabolites with clinical features in ICP patients. Our data suggest that disturbances in metabolic pathways might be associated with adverse pregnancy outcomes.

Abstract
Intrahepatic cholestasis is the most common hepatobiliary complication of pregnancy. Worsening cholestasis, measured by total bile acid levels, has been associated with an increased incidence of adverse fetal outcomes; however, maternal morbidity remains rare. This report highlights a case of severe fat-soluble vitamin deficiency suspected to be secondary to severe cholestasis. Active management with weekly vitamin supplementation and close outpatient follow-up resulted in the delivery of a 32-week healthy neonate. We propose consideration of screening for fat-soluble vitamin deficiency for patients whose pregnancy is complicated by severe cholestasis or early-onset cholestasis. Cholestasis induced severe fat-soluble vitamin deficiency. Managed with weekly vitamin K and close outpatient monitoring. Shared decision making for planned induction of labor at 32-week gestation. Healthy neonate delivered without maternal or fetal complications. Consider screening for fat-soluble vitamin deficiency in severe cholestasis cases.

Abstract
The liver disorders unique to pregnancy include hyperemesis gravidarum, intrahepatic cholestasis of pregnancy, acute fatty liver of pregnancy, and preeclampsia-associated hepatic impairment, specifically hemolysis, elevated liver enzymes, and low platelet count syndrome (HELLP). Their importance lies in the significant maternal and fetal/neonatal morbidity and mortality. Expeditious diagnosis and clinical evaluation is critical to ensure timely, appropriate care and minimize risks to the pregnant woman and her fetus/baby. A multidisciplinary approach is essential, including midwives, maternal-fetal-medicine specialists, anesthetists, neonatologists, and hepatologists.

Abstract
AIM To analyze the presence of fetal myocardial dysfunction in intrahepatic cholestasis of pregnancy (ICP) at diagnosis. METHODS This prospective cohort study included 49 pregnant participants with ICP at diagnosis and 49 nonaffected controls from a single public hospital. ICP was diagnosed based on clinical symptoms after excluding other causes of pruritus and presence of autoimmune diseases. Total bile acids were not obtained in this cohort. ICP pregnancies were assessed with a functional echocardiography at diagnosis including PR-interval, isovolumetric contraction time (ICT), ejection time (ET), and isovolumetric relaxation time (IRT) for electrical, systolic, and diastolic function, respectively. Controls were assessed at recruitment. Perinatal outcomes were obtained from delivery books. The main outcome was the presence of PR-interval prolongation or first-degree fetal heart block, and echographic signs of diastolic and systolic dysfunction. RESULTS Compared to controls, ICP were above upper limit in conjugated bilirubin (2.0% vs. 20.4%; p = 0.008), aspartate aminotransferase (2.0% vs. 24.5%; p = 0.002), and alanine aminotransferase (4.1% vs. 28.6%; p = 0.002). ICP was associated with a higher PR-interval (130 ± 12 ms vs. 121 ± 6 ms; p < 0.0001) with five first-degree fetal heart blocks. IRT was significantly higher in ICP (42 ± 6 ms vs. 37 ± 5 ms; p = 0.0001), with no differences in ICT and ET. PR-interval trend was only positively correlated with IRT in ICP pregnancies (p = 0.04 and p = 0.34, in ICP and controls, respectively). CONCLUSIONS Our study demonstrates that fetuses affected by maternal ICP are associated with electrical and diastolic myocardial dysfunction. More studies focused on antenatal and postnatal functional echocardiography are necessary to validate our results and consider these markers in the clinical management of ICP pregnancies.

Abstract
This study aimed to evaluate the relationship between intrahepatic cholestasis of pregnancy (ICP) and Vitamin D and B12 levels. The study was a retrospective, cross-sectional, case-control study that evaluated 92 ICP cases and 102 pregnant women without any additional disease. ICP cases were grouped as mild and severe according to their total bile acid (TBA) levels, and their relationship with Vitamin D and B12 levels and perinatal outcomes was evaluated. Vitamin D and B12 levels of the ICP group were significantly lower than those of the control group. There was a moderate negative correlation between TBA and Vitamin D levels and a low negative correlation between TBA and Vitamin B12 levels. Adverse neonatal outcomes were significantly higher in the severe ICP group than in the mild ICP group. IMPACT STATEMENTWhat is already known on this subject? The pathophysiology of ICP, which can lead to adverse perinatal outcomes, is not yet fully understood, and there is no preventive treatment.What do the results of this study add? This study showed that Vitamins B12 and D levels were low in women with ICP and that TBA levels were negatively correlated with Vitamin D and B12 levels.What are the implications of these findings for clinical practice and/or further research? This study may guide future studies in terms of explaining the etiopathogenesis of ICP and developing treatment options.

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
OBJECTIVES Considering the effects of bile-acid levels on fetal lungs and pulmonary surfactants, we hypothesized that in the presence of intrahepatic pregnancy cholestasis (ICP), poor neonatal respiratory problems are observed in relation to the severity of the disease. Delivery timing with the presence of ICP is scheduled during late-preterm and early term gestational weeks. The aim of this study was to assess ICP and disease severity effects on transient tachypnea of the newborn (TTN) in uncomplicated fetuses. METHODS This study comprised 1,097 singleton pregnant women who were separated into three groups-control, mild ICP, and severe ICP. The pregnant women diagnosed with ICP between January 2010 and September 2020 was investigated using the hospital's database. For the control group, healthy pregnant women who met the same exclusion criteria and were similar in terms of maternal age, gestational age at delivery, and mode of delivery were analyzed. RESULTS The TTN rate was 14.5% in the severe ICP group, 6.5% in the mild ICP group, and 6.2% in the control group. The TTN rate in the severe ICP group was significantly higher than that in the other groups (p<0.001). Similarly, the rate of admission to the neonatal intensive care unit was significantly higher in the severe ICP group than in the other groups (p<0.001). According to Pearson correlation analyses, maternal serum bile-acid levels were positively correlated with TTN (r=0.082; p=0.002). CONCLUSIONS Severe ICP, but not mild ICP, and serum bile-acid levels were positively correlated with increased TTN risk and reduced pulmonary surfactant levels.

Abstract
INTRODUCTION Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-associated hepatic disorder characterized by pruritus in the setting of elevated serum bile acids (BA). Risk factors for the disease include preexisting hepatobiliary disease, personal or family history of ICP, and advanced maternal age. Recent data suggests that patients with severe ICP (BA ≥100 μmol/L) have a higher risk of adverse pregnancy outcomes including stillbirth. MATERIAL AND METHODS This was a retrospective cohort study of patients diagnosed with ICP between 2012 and 2019 at a tertiary referral center. ICP was defined as symptomatic pruritus combined with serum BA >10 μmol/L. Maternal characteristics and outcomes were abstracted from electronic medical records. Baseline characteristics were compared between patients with mild (BA <40 μmol/L), moderate (BA 40-99 μmol/L) and severe (BA ≥100 μmol/L) ICP. Obstetrics and neonatal outcomes for patients in each category were then analyzed. Shapiro-Wilk test was used to test for normality for continuous variables, and ANOVA, Kruskal-Wallis, Chi-squared or Fisher's exact tests were used as appropriate. A p-value <.05 was considered statistically significant. RESULTS 438 patients were included in the analysis. Individuals with pregestational diabetes (p < .01), history of ICP (p < .01), prior cholecystectomy (p < .01), and tobacco use (p < .05) were more likely to have severe disease. When compared to individuals with moderate and mild disease, individuals with severe disease were more likely to be diagnosed earlier (29w1d vs 34w1d vs 34w1d, p < .05), have gestational diabetes (50% vs 6% vs 13%, p < .01), hypertensive disorders of pregnancy (42% vs 10% vs 15%, p = .02), and abnormal aspartate aminotransferase (91% vs 65% vs 27%, p < .01) and alanine aminotransferase levels (91% vs 60% vs 26%, p < .01). There were no differences in preterm labor, meconium-stained amniotic fluid, or neonatal respiratory distress syndrome and no stillbirths in this cohort. CONCLUSIONS In patients with ICP, those with pregestational diabetes, history of ICP, prior cholecystectomy, and tobacco use are more likely to develop severe disease. Given the adverse outcomes associated with severe disease, serial BA measurements to monitor for development of severe disease may be warranted in this population.

Alpha-1 Antitrypsin Z Variant (AAT PI*Z) as a Risk Factor for Intrahepatic Cholestasis of Pregnancy. Front Genet 2021; 12:720465. [PMID: 34557220 PMCID: PMC8454405 DOI: 10.3389/fgene.2021.720465] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2021] [Accepted: 07/27/2021] [Indexed: 11/18/2022] Open
Abstract
Background: Intrahepatic cholestasis of pregnancy (ICP; prevalence 0.2–15.6%) is the most common pregnancy-related liver disorder. It may have serious consequences for a pregnancy, including increased risk of preterm delivery, meconium staining of amniotic fluid, fetal bradycardia, distress, and fetal demise. In cases of high bile acids (>100μmol/L), patients have 10-fold increase in the risk of stillbirth. Biophysical methods of fetal monitoring, such as cardiotocography, ultrasonography, or Doppler have been proven unreliable for risk prediction in the course of intrahepatic cholestasis. Therefore, we believe extensive research for more specific, especially early, markers should be carried out. By analogy with cholestasis in children with inherited alpha-1 antitrypsin deficiency (AATD), we hypothesized the SERPINA1 Z pathogenic variant might be related to a higher risk of cholestasis in pregnancy. This study aimed to investigate the most common AATD variants (Z and S SERPINA1 alleles) in a group of cholestatic pregnant women. Results: The Z carrier frequency was calculated to be 6.8%, which is much higher compared to the general population [2.3%; the Chi-squared test with Yates correction is 6.8774 (p=0.008)]. Conclusion: Increased prevalence of SERPINA1 PI*Z variant in a group of women with intrahepatic cholestasis may suggest a possible genetic origin of a higher risk of intrahepatic cholestasis in pregnancy.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) is a rare but potentially serious complication of pregnancy, the main symptom of which is intense pruritus with elevated serum levels of bile acids. The elevated serum bile acid concentration is regarded as a predictor for poor perinatal outcome including intrauterine death. Ursodeoxycholic acid (UDCA) has become established as the treatment of choice in clinical management to achieve a significant improvement in symptoms and reduce the cholestasis. Pregnant women with severe intrahepatic cholestasis should always be managed in a perinatal centre with close interdisciplinary monitoring and treatment involving perinatologists and hepatologists to minimise the markedly increased perinatal morbidity and mortality as well as maternal symptoms.

Abstract
OBJECTIVES Multicentre international trials relying on diagnoses derived from biochemical results may overlook the importance of assay standardisation from the participating laboratories. Here we describe a study protocol aimed at harmonising results from total bile acid determinations within the context of an international randomised controlled Trial of two treatments, URsodeoxycholic acid and RIFampicin, for women with severe early onset Intrahepatic Cholestasis of pregnancy (TURRIFIC), referred to as the Bile Acid Comparison and Harmonisation (BACH) study, with the aims of reducing inter-laboratory heterogeneity in total bile acid assays. METHODS We have simulated laboratory data to determine the feasibility of total bile acid recalibration using a reference set of patient samples with a consensus value approach and subsequently used regression-based techniques to transform the data. RESULTS From these simulations, we have demonstrated that mathematical recalibration of total bile acid results is plausible, with a high probability of successfully harmonising results across participating laboratories. CONCLUSIONS Standardisation of bile acid results facilitates the commutability of laboratory results and collation for statistical analysis. It may provide the momentum for broader application of the described techniques in the setting of large-scale multinational clinical trials dependent on results from non-standardised assays.

Abstract
The knowledge about surfactant biology is now deeper and recent research has allowed to clarify its role in several human lung disorders. The balance between surfactant production and consumption is better known and the same applies to their regulatory mechanisms. This has allowed to hypothesize and investigate several new and original strategies to protect surfactant and enhance its activity. These interventions are potentially useful for several disorders and particularly for acute respiratory distress syndrome. We here highlight the mechanisms regulating surfactant consumption, encompassing surfactant catabolism but also surfactant injury due to other mechanisms, in a physiopathology-driven fashion. We then analyze each corresponding strategy to protect surfactant and enhance its activity. Some of these strategies are more advanced in terms of research & development pathway, some others are still investigational, but all are promising and deserve a joint effort from clinical-academic researchers and the industry.

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
IMPORTANCE Bile acids play essential roles in metabolic modulation. Excessive serum total bile acid (sTBA) levels during pregnancy are associated with adverse perinatal outcomes; however, their association with the risk of intrauterine growth restriction (IUGR) remains unclear. OBJECTIVE To investigate the association between maternal sTBA concentration during pregnancy and the risk of IUGR. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study included pregnant individuals who delivered live singleton neonates and had regular antenatal examination records available at a hospital-based center in Shanghai, China, from 2014 to 2018. Data were analyzed from July to November 2020. EXPOSURES Maternal sTBA concentration during pregnancy. MAIN OUTCOMES AND MEASURES Fetal birth weight and probability of low birth weight (LBW) and IUGR. RESULTS This study included 68 245 singleton pregnancies with live births for analysis. The mean (SD) age of the pregnant individuals was 30.5 (3.8) years, 67 168 patients (98.4%) were Han, and 50 155 (73.5%) were nulliparous. Nonlinear regression models suggested that there was an inverted J-shaped association between maternal sTBA level during pregnancy and fetal birth weight, with a steep decrease in birth weight at high sTBA levels (estimated mean [SE] birth weight for sTBA of 40.8 ug/mL, 2879 [39.9] g) and greater birth weights at lower sTBA levels (estimated mean [SE] birth weight for sTBA 0.4 μg/mL, 3290 [3.9] g; and for 4.1 μg/mL, 3334 [1.6] g). Lower birth weight and a higher incidence of IUGR were observed in patients with gestational hypercholanemia (sTBA ≥4.08 μg/mL) compared with those without gestational hypercholanemia (birth weight: estimated adjusted mean [SE], 3309 [3.32] vs 3338 [0.80] g; P = .005; incidence of IUGR: 62 of 4467 [1.4%] vs 312 of 63 778 [0.5%]; P < .001). Moreover, compared with patients with sTBA concentrations of less than 4.08 μg/mL, those with gestational hypercholanemia had an increased risk of LBW (adjusted odds ratio [aOR], 1.29; 95% CI, 1.09-1.53) and IUGR (aOR, 2.18; 95% CI, 1.62-2.91). In addition, there was an additive interaction between hypertensive disorders in pregnancy (HDP) and hypercholanemia on LBW and IUGR risk. The highest risks of LBW and IUGR were found in pregnant individuals with both HDP and hypercholanemia compared with those with normotensive pregnancies with sTBA concentrations less than 4.08 μg/mL (LBW: aOR, 9.13; 95% CI, 6.88-12.12; IUGR: aOR, 19.14; 95% CI, 12.09-30.28). CONCLUSIONS AND RELEVANCE This study found that gestational hypercholanemia was associated with an increased risk of LBW and IUGR, especially in pregnant individuals with HDP. Therefore, it would be meaningful to monitor sTBA concentration during the follow-up of pregnancies with potential IUGR.

Abstract
BACKGROUND Ursodeoxycholic acid is commonly used to treat intrahepatic cholestasis of pregnancy, yet its largest trial detected minimal benefit for a composite outcome (stillbirth, preterm birth, and neonatal unit admission). We aimed to examine whether ursodeoxycholic acid affects specific adverse perinatal outcomes. METHODS In this systematic review and individual participant data meta-analysis, we searched PubMed, Web of Science, Embase, MEDLINE, CINAHL, Global Health, MIDIRS, and Cochrane without language restrictions for relevant articles published between database inception, and Jan 1, 2020, using search terms referencing intrahepatic cholestasis of pregnancy, ursodeoxycholic acid, and perinatal outcomes. Eligible studies had 30 or more study participants and reported on at least one individual with intrahepatic cholestasis of pregnancy and bile acid concentrations of 40 μmol/L or more. We also included two unpublished cohort studies. Individual participant data were collected from the authors of selected studies. The primary outcome was the prevalence of stillbirth, for which we anticipated there would be insufficient data to achieve statistical power. Therefore, we included a composite of stillbirth and preterm birth as a main secondary outcome. A mixed-effects meta-analysis was done using multi-level modelling and adjusting for bile acid concentration, parity, and multifetal pregnancy. Individual participant data analyses were done for all studies and in different subgroups, which were produced by limiting analyses to randomised controlled trials only, singleton pregnancies only, or two-arm studies only. This study is registered with PROSPERO, CRD42019131495. FINDINGS The authors of the 85 studies fulfilling our inclusion criteria were contacted. Individual participant data from 6974 women in 34 studies were included in the meta-analysis, of whom 4726 (67·8%) took ursodeoxycholic acid. Stillbirth occurred in 35 (0·7%) of 5097 fetuses among women with intrahepatic cholestasis of pregnancy treated with ursodeoxycholic acid and in 12 (0·6%) of 2038 fetuses among women with intrahepatic cholestasis of pregnancy not treated with ursodeoxycholic acid (adjusted odds ratio [aOR] 1·04, 95% CI 0·35-3·07; p=0·95). Ursodeoxycholic acid treatment also had no effect on the prevalence of stillbirth when considering only randomised controlled trials (aOR 0·29, 95% CI 0·04-2·42; p=0·25). Ursodeoxycholic acid treatment had no effect on the prevalence of the composite outcome in all studies (aOR 1·28, 95% CI 0·86-1·91; p=0·22), but was associated with a reduced composite outcome when considering only randomised controlled trials (0·60, 0·39-0·91; p=0·016). INTERPRETATION Ursodeoxycholic acid treatment had no significant effect on the prevalence of stillbirth in women with intrahepatic cholestasis of pregnancy, but our analysis was probably limited by the low overall event rate. However, when considering only randomised controlled trials, ursodeoxycholic acid was associated with a reduction in stillbirth in combination with preterm birth, providing evidence for the clinical benefit of antenatal ursodeoxycholic acid treatment.

Growth Abnormalities as a Risk Factor of Adverse Neonatal Outcome in Hypertensive Pregnancies-A Single-Center Retrospective Cohort Study. CHILDREN-BASEL 2021; 8:children8060522. [PMID: 34205263 PMCID: PMC8234699 DOI: 10.3390/children8060522] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Revised: 06/07/2021] [Accepted: 06/17/2021] [Indexed: 11/23/2022]
Abstract
(1) Background: Hypertensive disorders of pregnancy (HDP) include gestational hypertension (GH), chronic hypertension (CH), preeclampsia (PE), and preeclampsia superimposed on chronic hypertension (CH with PE). HDP is associated with several short and long-term perinatal and neonatal complications, such as newborn growth restriction and death. This study aimed to establish the association between HDP, newborn growth abnormalities, and neonatal outcome. (2) Methods: This is a single-center retrospective cohort study of 63651 singleton deliveries. (3) Results: Univariate analysis showed a significantly increased risk of intrauterine and neonatal death associated with maternal hypertension and growth disorders. There were differences between growth charts used, with the highest risk of stillbirth for SGA defined by the Intergrowth chart (OR 17.2) and neonatal death for newborn growth restriction (NGR) based on Intergrowth (OR 19.1). Multivariate analysis showed that NGR is a stronger risk factor of neonatal death than SGA only. (4) Conclusions: HDP is significantly associated with growth abnormalities and is an independent risk factor of adverse outcomes. The presence of newborn growth restriction is strongly associated with the risk of neonatal death. The choice of growth chart has a substantial effect on the percentage of diagnosis of SGA and NGR.

Abstract
OBJECTIVE Although intrahepatic cholestasis of pregnancy (ICP) remains poorly understood, there are several perinatal complications associated with this condition. This study aimed to examine perinatal outcomes of women with ICP, evaluate outcomes according to severity of disease, and monitor time to symptom improvement following diagnosis. STUDY DESIGN It involves a prospective, observational study of women with ICP at a single institution. Women with new-onset pruritus without rash were referred to a high-risk obstetrics clinic and evaluated with fasting total bile acids (TBA). Laboratory-confirmed ICP was defined as fasting TBA ≥10 µmol/L. Following diagnosis, a standardized protocol was utilized, including treatment with ursodeoxycholic acid (UDCA). Perinatal outcomes were compared amongst those with and without ICP, and to the general population. Women with ICP were further analyzed based on maximum TBA: 10 to 39, 40 to 99, and ≥100 µmol/L. A Kaplan-Meier survival curve was used to analyze time to symptom improvement. RESULTS A total of 404 patients were evaluated and 212 (52%) were diagnosed with ICP. The mean gestational age at diagnosis was 34.1 ± 3.3 weeks. When comparing those with ICP to those not confirmed, and to the general population, there were no differences in age, parity, mode of delivery, preeclampsia, or stillbirth (p > 0.05). Preterm birth was significantly associated with ICP (p < 0.01). This relationship was significant across increasing severity of TBA (p < 0.01) and persisted when examining rates of spontaneous preterm birth (p < 0.01). All women with fasting TBA ≥40 µmol/L delivered preterm due to premature rupture of membranes or spontaneous labor. Time to symptom improvement after diagnosis was over 2 weeks on average; however, this time increased with worsening severity of disease. CONCLUSION Despite treatment with UDCA, women with ICP are at increased risk for spontaneous preterm birth, and this risk significantly increased with severity of disease. Although not significant, a trend exists between increasing time to symptom improvement and worsening severity of disease. KEY POINTS · Preterm birth is significantly increased in patients diagnosed with intrahepatic cholestasis of pregnancy.. · The risk of preterm birth in women with ICP increases across increasing strata of disease.. · Following initiation of treatment in patients with ICP, symptom improvement takes more than 2 weeks..

Abstract
AIM Intrahepatic cholestasis of pregnancy (ICP) is associated with safe maternal outcomes but perinatal outcomes have been variable. We assessed clinical factors and impact of bile acid levels on maternal and neonatal outcomes in ICP. METHODS Patients with ICP (defined as pruritus with serum bile acids ≥ 10 mmol/l) were included prospectively with an assessment of risk factors, modes of delivery as well as maternal and neonatal outcomes. Mild and severe ICP were diagnosed when serum bile acid was always <40 mmol/l and ≥40 mmol/l, respectively. Patients with gestational pruritus served as controls. RESULTS Out of 643 patients, 375 patients (mean age 29 ± 7.6 years, 45.8% primigravida) met inclusion criteria. Pregnancy-induced hypertension [PIH: 10.5%; odds ratio (OR): 4.8; 95% confidence interval (CI): 2.4-8.5; P = 0.0014], gestational diabetes (GDM: 12.5%; OR: 2.6; 95% CI: 2.3-4.1; P = 0.045) and spontaneous preterm labor (15.1%; OR: 2.5; 95% CI: 1.2-3.5; P = 0.040) were higher in patients with ICP. Ursodeoxycholic acid (UDCA) (median dose 900 mg; 600-1800 mg) ameliorated symptoms of cholestasis, bile acid levels and liver aminotransferases in 79% cases. When compared with patients with mild ICP, patients with severe ICP presented at a lower gestational period (26 vs. 32 weeks, P = 0.036), required frequent induction (12.5%; OR: 3.2; 95% CI: 2.1-5.6; P = 0.045) and had increased fetal distress (15%; OR: 1.9; 95% CI: 1.3-4.9; P = 0.048).Overall eight stillbirths were recorded. CONCLUSION Severe ICP is associated with a higher incidence of GDM and PIH, risk of pre-term labor, elective induction and stillbirths. UDCA remains a first-line agent in treating ICP.
