A Rare Case of Recurrent Intrahepatic Cholestasis of Pregnancy With Prolonged Postpartum Hepatic Inflammation Despite Normalization of Bile Acid Levels. GASTRO HEP ADVANCES 2022; 2:46-48.

Abstract
Intrahepatic cholestasis of pregnancy is one of the most common liver diseases during the second and third trimesters of pregnancy, but its pathogenesis remains unclear. Intrahepatic cholestasis of pregnancy is associated with elevations of maternal bile acids, serum aminotransferases, and adverse fetal outcomes. Besides direct cytotoxic liver injury by bile acids, it has been suggested that bile acid-induced oxidative stress and mitochondrial injury lead to a cascade of inflammatory responses. Here, we demonstrate that the extended elevation of serum aminotransferases after normalization of bile acid levels coincides with an extended increase of the chemokine CXCL10 and inflammatory cytokines.

[PMID: 36008054 DOI: 10.1016/j.ajog.2022.06.013] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Revised: 06/01/2022] [Accepted: 06/11/2022] [Indexed: 11/17/2022]
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.

Abstract
Introduction Intrahepatic cholestasis of pregnancy (IHCP) is characterized by pruritus of the hand and sole with abnormal liver function test and bile acid metabolism. IHCP occurs in the second and third trimesters of pregnancy and usually resolves after delivery. The overall prevalence is about 1.2 to 1.5%. This study was conducted to assess the fetomaternal outcome according to maternal serum bile acids levels and its correlation with liver function tests in patients with IHCP. Material and methods This ambispective observational study was conducted in the department of Obstetrics and Gynecology (OBG) for two years at AIIMS Jodhpur, Rajasthan. It included all the pregnant women attending the outpatient department of OBG with the complaint of pruritis in the palm and sole after 28 weeks of pregnancy and diagnosed with intrahepatic cholestasis of pregnancy after investigations. Results Only 152 patients were diagnosed with IHCP out of 4,148 deliveries, with a prevalence of 3.6%. Among these, 140 (92.11%) had mild IHCP, 10 (6.58%) had moderate IHCP and two (1.32%) had severe IHCP. There was a significant difference between the birth weight in mild, moderate and severe IHCP (P-value 0.004). About 12.5% (n=19) of patients had meconium-stained liquor during delivery. Two patients (1.32%) with moderate IHCP had intrauterine fetal death in the third trimester, and 6.58% (n=10) neonates were kept on continuous positive airway pressure. Conclusions IHCP is associated with adverse fetal outcomes like spontaneous or iatrogenic preterm delivery, low birth weight, increase in the rate of lower section cesarean section (LSCS) and intrauterine death of a fetus. A significant correlation found between raised bile acid levels and variables of liver function test, hence cost-effectiveness and feasibility of liver function test (LFT) should be considered for the management of IHCP.

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
Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-specific liver disorder affecting 0.5-2% of pregnancies. The majority of cases present in the third trimester with pruritus, elevated serum bile acids and abnormal serum liver tests. ICP is associated with an increased risk of adverse outcomes, including spontaneous preterm birth and stillbirth. Whilst rare mutations affecting hepatobiliary transporters contribute to the aetiology of ICP, the role of common genetic variation in ICP has not been systematically characterised to date. Here, we perform genome-wide association studies (GWAS) and meta-analyses for ICP across three studies including 1138 cases and 153,642 controls. Eleven loci achieve genome-wide significance and have been further investigated and fine-mapped using functional genomics approaches. Our results pinpoint common sequence variation in liver-enriched genes and liver-specific cis-regulatory elements as contributing mechanisms to ICP susceptibility.

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
Autoimmune hepatitis (AIH) in pregnancy has many unique considerations. Evidence provided from single center studies with patient level data and nationwide population studies provide valuable insight into this complex situation. Because a planned pregnancy is a safer pregnancy, preconception counseling is a crucial opportunity to optimize care and risk stratify women with AIH. Women with chronic liver disease who receive preconception advice and counseling are more likely to achieve stable liver disease at conception and undergo appropriate variceal surveillance. Loss of biochemical response in pregnancy is associated with adverse outcomes in unstable disease. New onset AIH in pregnancy should be managed with classical treatment regimens. The continued use of immunosuppression in pregnancy, with the exception of mycophenolate mofetil, has not shown to adversely affect the rates of stillbirth or congenital malformation. Previously adopted immunosuppression withdrawal paradigms in pregnancy should no longer be considered advantageous, because remission loss postdelivery is likely (12%-86%). Population studies, report improved outcomes with preterm birth rates falling from 20% to 9%-13% in AIH pregnancies over a 20-year period. Newer data have also demonstrated an increased risk of gestational diabetes and hypertensive complications in AIH pregnancy, which has implications for management and preeclampsia prevention with aspirin use. This review aims to provide the framework to guide and manage pregnancy in AIH outlining pearls and pitfalls to ensure optimal outcomes for mother, baby and to reduce variation in practice.

Abstract
Stillbirth is a common and devastating pregnancy complication. The aim of this study was to review and compare the recommendations of the most recently published guidelines on the investigation and management of this adverse outcome. A descriptive review of guidelines from the American College of Obstetricians and Gynecologists (ACOG), the Royal College of Obstetricians and Gynecologists (RCOG), the Perinatal Society of Australia and New Zealand (PSANZ), the Society of Obstetricians and Gynecologists of Canada (SOGC) on stillbirth was carried out. Regarding investigation, there is consensus that medical history and postmortem examination are crucial and that determining the etiology may improve care in a subsequent pregnancy. All guidelines recommend histopathological examination of the placenta, genetic analysis and microbiology of fetal and placental tissues, offering less invasive techniques when autopsy is declined and a Kleihauer test to detect large feto-maternal hemorrhage, whereas they discourage routine screening for inherited thrombophilias. RCOG and SOGC also recommend a complete blood count, coagulopathies' testing, anti-Ro and anti-La antibodies' measurement in cases of hydrops and parental karyotyping. Discrepancies exist among the reviewed guidelines on the definition of stillbirth and the usefulness of thyroid function tests and maternal viral screening. Moreover, only ACOG and RCOG discuss the management of stillbirth. They agree that, in the absence of coagulopathies, expectant management should be considered and encourage vaginal birth, but they suggest different labor induction protocols and different management in subsequent pregnancies. It is important to develop consistent international practice protocols, in order to allow effective determination of the underlying causes and optimal management of stillbirths, while identifying the gaps in the current literature may highlight the need for future research.

Abstract
Objective To examine the association between low fetal fraction (FF) of cell free DNA determined at non-invasive prenatal screening (NIPS) and the subsequent risk of preterm birth in uncomplicated singleton pregnancy. Methods We retrospectively interrogated NIPS System and hospitalization records from April 2018 to August 2019 and obtained results from 1521 consecutive and uncomplicated women with singleton pregnancy in which plasma FF of cell free DNA at NIPS had been investigated together with birth outcomes. We examined the association between FF and preterm birth (PTB) by regression analysis. Results The incidence of preterm birth, low birthweight, and macrosomia in the study population was 5.06%, 2.89%, and 7.17%, respectively. FF at NIPS in the second to fourth quartiles (8.40-11.07, 11.08-13.70, and >13.70%, respectively) was associated with higher gestational age at delivery relative to the lowest quartile (<8.40%), with estimated mean increases of 0.27 weeks (95% CI: 0.05-0.49), 0.29 weeks (95% CI: 0.06-0.51), and 0.28 weeks (95% CI: 0.05-0.51), respectively (P for trend = 0.027). Low FF (< the 5th percentile) was associated with an increased risk of PTB (adjusted OR: 2.23, 95% CI: 1.01-4.98, P = 0.047) compared to normal FF (≥ the 5th and ≤ the 95th percentiles). In addition, when compared to women with normal FF and body mass index (BMI) <25 at NIPS, the risk of early PTB (< 34 weeks gestation) was remarkably significantly higher among those with low FF and BMI ≥25 (adjusted OR: 6.29, 95% CI: 1.71-23.15, P = 0.006). Conclusion Our study supports the association of low FF at NIPS with PTB (especially early PTB) for uncomplicated singleton pregnancy.

Front Cell Dev Biol 2022; 10:854425. [PMID: 35938169 PMCID: PMC9354660 DOI: 10.3389/fcell.2022.854425] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Accepted: 06/20/2022] [Indexed: 01/24/2023] Open
Abstract
Background: Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-specific complication characterized by pruritus without skin damage and jaundice. The poor perinatal outcomes include fetal distress, preterm birth, and unexpected intrauterine death. However, the mechanism of ICP leading to poor prognosis is still unclear. Methods: We analyzed 10 ICP and 10 normal placental specimens through quantitative proteomics of data-independent acquisition (DIA) to screen and identify differentially expressed proteins. GO, KEGG, COG/KOG, StringDB, InterProScan, Metascape, BioGPS, and NetworkAnalyst databases were used in this study. PITA, miRanda, TargetScan, starBase, and LncBase Predicted v.2 were used for constructing a competing endogenous RNA (ceRNA) network. Cytoscape was used for drawing regulatory networks, and cytoHubba was used for screening core nodes. The ICP rat models were used to validate the pathological mechanism. Results: GO, KEGG, and COG/KOG functional enrichment analysis results showed the differentially expressed proteins participated in autophagy, autophagosome formation, cofactor binding, JAK-STAT signaling pathway, and coenzyme transport and metabolism. DisGeNET analysis showed that these differentially expressed proteins were associated with red blood cell disorder and slow progression. We further analyzed first 12 proteins in the upregulated and downregulated differentially expressed proteins and incorporated clinicopathologic parameters. Our results showed HBG1, SPI1, HBG2, HBE1, FOXK1, KRT72, SLC13A3, MBD2, SP9, GPLD1, MYH7, and BLOC1S1 were associated with ICP development. ceRNA network analysis showed that MBD2, SPI1, FOXK1, and SLC13A3 were regulated by multiple miRNAs and lncRNAs. Conclusion: ICP was associated with autophagy. The ceRNA network of MBD2, SPI1, FOXK1, and SLC13A3 was involved in ICP progression, and these core proteins might be potential target.

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
INTRODUCTION The association between intrahepatic cholestasis of pregnancy (ICP) and maternal lipid metabolism remains unknown. This systematic review and meta-analysis aimed to evaluate the association between ICP and maternal lipid metabolism. MATERIAL AND METHODS We systematically searched Medline, Embase and the Cochrane Library (up to December 11, 2021) to identify relevant studies that investigated ICP and maternal plasma lipid concentrations. The weighted mean difference (WMD) and 95% confidence intervals (CI) were calculated using random-effects models. A subgroup analysis was conducted to identify the potential sources of heterogeneity. Potential publication bias was tested using funnel plots and the Egger's and Begg's tests. This meta-analysis was registered with PROSPERO (CRD42021293783). RESULTS Eleven studies were included in this qualitative analysis. A random-effects meta-analysis of data from the final included nine studies (n = 786 participants) showed a significant association between ICP and maternal dyslipidemia, with elevated levels of triglycerides (WMD, 0.67 mmol/L; 95% CI 0.39-0.95; P < 0.001), total cholesterol (WMD, 1.08 mmol/L; 95% CI 0.58-1.58; P < 0.001), low-density lipoprotein cholesterol (WMD, 1.08 mmol/L; 95% CI 0.53-1.64; P < 0.001), and reduced high-density lipoprotein cholesterol level (WMD, -0.38 mmol/L; 95% CI -0.53 to -0.23; P < 0.001) vs normal pregnancies. CONCLUSIONS The present study's findings support an association between ICP and maternal dyslipidemia. ICP pregnancies have dysregulated lipid metabolism vs normal pregnancies.

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
OBJECTIVE This study aimed to evaluate the effectiveness of fetal left ventricular modified myocardial performance index in predicting adverse perinatal outcomes for intrahepatic cholestasis of pregnancy. METHODS A cross-sectional study was conducted, including 51 women with intrahepatic cholestasis of pregnancy and 80 healthy controls. Using Doppler ultrasonography, E-wave, A-wave, isovolumetric contraction time, isovolumetric relaxation time, and ejection time were recorded and the left ventricular modified myocardial performance index was measured. RESULTS Findings showed that the mean left ventricular modified myocardial performance index, isovolumetric contraction time, and isovolumetric relaxation time values were statistically significantly higher while the ejection time and E/A ratios were statistically significantly lower in the intrahepatic cholestasis of pregnancy group than the control group. In the intrahepatic cholestasis of pregnancy group, a statistically significant positive correlation was found between left ventricular modified myocardial performance index and adverse perinatal outcomes in the intrahepatic cholestasis of pregnancy group (r=0.478, p<0.001), while a statistically significant negative correlation was found between the E/A ratio and adverse perinatal outcomes (r=-0.701, p<0.001). CONCLUSIONS For intrahepatic cholestasis of pregnancy cases, high fetal left ventricular modified myocardial performance index values were an indicator of ventricular dysfunction, and this correlated with negative perinatal outcomes.

Abstract
Pregnancy-related intrahepatic cholestasis (ICP) is a serious complication with adverse perinatal outcomes of preterm labor, fetal distress, or stillbirth. As a result, it is important to investigate and identify the potential critical pathogenic mechanisms of ICP. First, we collected the placental tissues from the ICP with placental weight and fetal birth weight loss for the whole transcriptome sequencing. Then we analyzed the differentially expressed (DE) circRNAs (DEcircRNAs) by SRPBM, DElncRNAs by FRKM, DEmiRNAs by TPM, and DEmRNAs by TPM and RSEM. Based on differential expression of term pregnancy placental tissues from pregnancies impacted by ICP (n=7) as compared to gestational aged matched control tissues (n=5), the circ/lncRNA-miRNA-mRNA competitive endogenous RNA (ceRNA) regulatory networks were constructed. The ceRNA regulatory networks covered 3,714 events, including 21 DEmiRNAs, 36 DEcircRNAs, 146 DElncRNAs, and 169 DEmRNAs. According to the functional analysis, ICP complications were linked to the immune system, signal transduction, endocrine system, cell growth and death, and transport and catabolism. Further evidence suggested that the expression of immune-related genes KLRD1, BRAF, and NFATC4 might have a potential ceRNA mechanism by individual lncRNA sponging miR372-3p, miR-371a-3p, miR-7851-3p, and miR-449a to control downstream the level of TNF-α, IFN-γ, and IL-10, thereby regulating the pathophysiology of ICP. Furthermore, our results were validated by the qRT-PCR, western blotting and ELISA assays. In conclusion, this study is the first to evaluate placental ceRNA networks in pregnancies affected by ICP, showing alterations in immune regulatory networks which may impact fetal and placental growth. Overall our these data suggest that the ceRNA regulatory network may refine biomarker predictions for developing novel therapeutic approaches in ICP.

Perinatal outcomes in twin late preterm pregnancies: results from an Italian area-based, prospective cohort study. Ital J Pediatr 2022; 48:101. [PMID: 35710441 PMCID: PMC9204959 DOI: 10.1186/s13052-022-01297-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Accepted: 06/10/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Multiple gestations represent a considerable proportion of pregnancies delivering in the late preterm (LP) period. Only 30% of LP twins are due to spontaneous preterm labor and 70% are medically indicated; among this literature described that 16-50% of indicated LP twin deliveries are non-evidence based. As non-evidence-based delivery indications account for iatrogenic morbidity that could be prevented, the objective of our observational study is to investigate first neonatal outcomes of LP twin pregnancies according to gestational age at delivery, chorionicity and delivery indication, then non evidence-based delivery indications. METHODS Prospective cohort study among twins infants born between 34 + 0 and 36 + 6 weeks, in Emilia Romagna, Italy, during 2013-2015. The primary outcome was a composite of adverse perinatal outcomes. RESULTS Among 346 LP twins, 84 (23.4%) were monochorionic and 262 (75.7%) were dichorionic; spontaneous preterm labor accounted for 85 (24.6%) deliveries, preterm prelabor rupture of membranes for 66 (19.1%), evidence based indicated deliveries were 117 (33.8%), while non-evidence-based indications were 78 (22.5%). When compared to spontaneous preterm labor or preterm prelabor rupture of membranes, pregnancies delivered due to maternal and/or fetal indications were associated with higher maternal age (p < 0.01), higher gestational age at delivery (p < 0.01), Caucasian race (p 0.04), ART use (p < 0.01), gestational diabetes (p < 0.01), vaginal bleeding (p < 0.01), antenatal corticosteroids (p < 0.01), diagnosis of fetal growth restriction (FGR) (p < 0.01), and monochorionic (p < 0.01). Two hundred twenty-six pregnancies (65.3%) had at least one fetus experiencing one composite of adverse perinatal outcome. Multivariate analysis confirmed that delivery indication did not affect the composite of adverse perinatal outcomes; the only characteristic that affect the outcome after controlling for confounding was gestational age at delivery (p < 0.01). Moreover, there was at least one adverse neonatal outcome for 94% of babies born at 34 weeks, for 73% of those born at 35 weeks and for 46% of those born at 36 weeks (p < 0.01). CONCLUSION Our study suggests that the decision to deliver or not twins in LP period should consider gestational age at delivery as the main determinant infants' prognosis. Delivery indications should be accurately considered, to avoid iatrogenic early birth responsible of preventable complications.

Deep Learning Algorithm-Based Magnetic Resonance Imaging Feature-Guided Serum Bile Acid Profile and Perinatal Outcomes in Intrahepatic Cholestasis of Pregnancy. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:8081673. [PMID: 35707042 PMCID: PMC9192280 DOI: 10.1155/2022/8081673] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Revised: 05/06/2022] [Accepted: 05/09/2022] [Indexed: 11/27/2022]
Abstract
This study was aimed to explore magnetic resonance imaging (MRI) based on deep learning belief network model in evaluating serum bile acid profile and adverse perinatal outcomes of intrahepatic cholestasis of pregnancy (ICP) patients. Fifty ICP pregnant women diagnosed in hospital were selected as the experimental group, 50 healthy pregnant women as the blank group, and 50 patients with cholelithiasis as the gallstone group. Deep learning belief network (DLBN) was built by stacking multiple restricted Boltzmann machines, which was compared with the recognition rate of convolutional neural network (CNN) and support vector machine (SVM), to determine the error rate of different recognition methods on the test set. It was found that the error rate of deep learning belief network (7.68%) was substantially lower than that of CNN (21.34%) and SVM (22.41%) (P < 0.05). The levels of glycoursodeoxycholic acid (GUDCA), glycochenodeoxycholic acid (GCDCA), and glycocholic acid (GCA) in the experimental group were dramatically superior to those in the blank group (P < 0.05). Both the experimental group and the blank group had notable clustering of serum bile acid profile, and the experimental group and the gallstone group could be better distinguished. In addition, the incidence of amniotic fluid contamination, asphyxia, and premature perinatal infants in the experimental group was dramatically superior to that in the blank group (P < 0.05). The deep learning confidence model had a low error rate, which can effectively extract the features of liver MRI images. In summary, the serum characteristic bile acid profiles of ICP were glycoursodeoxycholic acid, glycochenodeoxycholic acid, and glycocholic acid, which had a positive effect on clinical diagnosis. The toxic effects of high concentrations of serum bile acids were the main cause of adverse perinatal outcomes and sudden death.

Abstract
Epidemiological and animal experimental studies suggest an association between gestational cholestasis and intrauterine growth restriction (IUGR). Here, we explored the mechanism through which gestational cholestasis induced IUGR. To establish gestational cholestasis model, pregnant mice were subcutaneously injected with 17α-Ethynylestradiol (E2) on gestational day 13 (GD13)-GD17. Some pregnant mice were intraperitoneally injected with 4μ8C on GD13-GD17. The results found that the apoptosis of trophoblast cells was elevated in placentas of mice with gestational cholestasis and in deoxycholic acid (DCA)-treated human trophoblast cell lines and primary mouse trophoblast cells. Correspondingly, the levels of placental cleaved caspase-3 and Bax were increased, while placental Bcl2 level was decreased in mice with gestational cholestasis and in DCA-treated trophoblast cells. Further analysis found that placental IRE1α pathway was activated in mice with gestational cholestasis and in DCA-treated trophoblast cells. Interestingly, 4μ8C, an IRE1α RNase inhibitor, significantly inhibited caspase-3 activity and apoptosis of trophoblast cells in vivo and in vitro. Importantly, 4μ8C rescued gestational cholestasis-induced placental insufficiency and IUGR. Furthermore, a case-control study demonstrated that placental IRE1α and caspase-3 pathways were activated in cholestasis cases. Our results provide evidence that gestational cholestasis induces placental insufficiency and IUGR may be via triggering IRE1α-mediated apoptosis of placental trophoblast cells.

Abstract
OBJECTIVES To investigate the prevalence of preterm birth (PTB) and the risk factors for different gestational age subgroups of preterm birth in China. METHODS We carried out a descriptive cross-sectional study encompassing all singleton live births (24+0 to 41+6 weeks) with completed data in 23 provinces in China from 2010 to 2017 during investigation period. We compared both the preterm group (24+0 to 36+6 weeks) and preterm subgroups (<32 weeks, 32+0 to 33+6 weeks, and 34+0 t0 36+6 weeks) with the term group (37+0 to 41+6 weeks). We collected information on maternal and fetal characteristics from medical records. Logistic regression was use. RESULTS The prevalence of PTB was 7.4% (15,833/215,254) in singleton births. After adjusting for maternal age, parity, and potential risk factors in univariate analysis, the high-risk factors for PTB at <32 weeks were placental abruption (aOR=41.52; 95% CI, 25.89-66.58), placenta previa (aOR=40.04; 95% CI, 32.00-50.09), chorioamnionitis (aOR=11.06; 95% CI, 8.738-14.02), and hypertension disorders in pregnancy (HDP) (aOR=3.564; 95% CI, 2.930-4.335). Intrahepatic cholestasis of pregnancy (ICP) was significantly associated with PTB at 34-36 weeks (aOR=5.763; 95% CI, 5.049-6.577), particularly with spontaneous PTB (aOR=10.04; 95% CI, 8.79-11.47). Gestational diabetes mellitus (GDM) was significantly associated with PTB at 34-36 weeks only (aOR=1.156; 95% CI, 1.054-1.267). CONCLUSION Placental abruption, placenta previa, chorioamnionitis, and HDP were more predictive of early PTB; GDM and ICP were more predictive of late PTB.

Abstract
Abstract
Background
Intrahepatic cholestasis of pregnancy (ICP) is characterized by skin pruritus and impaired liver function. Hepatitis B virus (HBV) infection increases the risk of developing ICP. HBV infection is associated with oxidative stress, which has been proven to participate in the development of ICP. The goal of this study was to explore the relationship among HBV, oxidative stress, and ICP, and investigate whether a biomarker of oxidative stress may predict the diagnosis and severity of ICP.
Methods
We induced a retrospective cohort of 70 ICP patients from January 2019 to December 2020, and compared their data with those from healthy pregnant women (n = 70). Serum levels of an oxidative stress marker superoxide dismutase (SOD) were examined using an enzyme-linked immunosorbent assay (ELISA). Diagnostic and prognostic values of serum SOD were analyzed by receiver operating characteristic (ROC) curve.
Results
Pregnant women in the ICP group had significantly higher level of serum SOD (243.24 ± 12.57 U/L vs 98.70 ± 2.95 U/L, p < 0.01) and a higher rate of HBV infection (51.53% vs 25.71%, p < 0.05) compared with the control group. HBsAg-positive ICP patients had a higher levels of serum SOD (287.24 ± 19.21 U/L vs 196.65 ± 11.75 U/L, p < 0.01) compared with HBsAg-negative ICP patients. A serum SOD level > 121.4 U/mL might be used to predict ICP, while a serum SOD level > 274.6 U/mL might predict ICP severity.
Conclusion
HBV infection promotes oxidative stress during the pathogenesis of ICP. Serum levels of SOD could be used to predict ICP diagnosis and severity. Modification of oxidative stress might be a treatment target for ICP.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) is a common pregnancy-specific disease, characterized by increased bile acid levels and adverse fetal outcomes. We previously reported excessive bile acids led to dysfunction of placental trophoblasts in ICP. However, the detailed mechanism is still unclear. Autophagy is fundamental process for protecting cell survival against adverse conditions. Here, we evaluated the effect of increased concentration of bile acids on autophagy in trophoblasts in vitro and in vivo. First, we demonstrated that the autophagy substrate p62/sequestosome-1 was accumulated in placental tissues from patients with ICP and in human trophoblasts treated with hydrophobic bile acids, including chenodeoxycholic acid and deoxycholic acid. Furthermore, we found that treatment with hydrophobic bile acids impaired autophagic flux in both time- and concentration-dependent manners, by suppressing the AMP-activated protein kinase/unc-51-like kinase 1 autophagic signaling pathway. Notably, trophoblasts were prone to apoptotic cell death upon starvation along with bile-acids treatment in vitro or in an ICP mouse model in vivo. Additionally, we revealed mitochondrial dysfunction was the predominant biological process in excessive bile acids induced trophoblast impairment under starvation by proteomic assay. Collectively, our study proposed a complex interaction of excessive bile acids induced autophagic flux, mitochondrial dysfunction, and cellular apoptosis in placental trophoblasts may play a critical role in the pathogenesis of ICP.

Abstract
Background Intrahepatic cholestasis of pregnancy (ICP) is closely related to the occurrence of adverse outcomes. Currently, total bile acids (TBAs) are the only diagnostic index for ICP, and its sensitivity and specificity have certain limitations. In this study, we aimed to develop potential biomarkers for the diagnosis of ICP. Methods Sixty pregnant women diagnosed with ICP and 48 healthy pregnant controls were enrolled in this study. We used the Agilent microRNA (miRNA) array followed by quantitative reverse transcriptase polymerase chain reaction assays to identify and validate the serum exosome miRNA profiles in ICP and healthy pregnant controls. We employed bioinformatics to identify metabolic processes associated with differentially expressed serum exosome miRNAs. Results The expression levels of hsa-miR-4271, hsa-miR-1275, and hsa-miR-6891-5p in maternal serum exosomes were significantly lower in ICP patients compared to controls; the diagnostic accuracy of hsa-miR-4271, hsa-miR-1275, and hsa-miR-6891-5p was evaluated with the area under the receiver operating characteristic curve (AUC) values of 0.861, 0.886, and 0.838, respectively. Multiple logistic regression analysis showed that a combination of the levels of hsa-miR-4271and hsa-miR-1275 afforded a significantly higher AUC (0.982). The non-error rate of a combination of all three exosome miRNAs was the highest (95%), thus more reliable ICP diagnosis. The expression levels of all three exosome miRNAs were negatively associated with TBAs. Furthermore, according to bioinformatics analysis, the three exosome miRNAs were related to lipid metabolism, apoptosis, oxidative stress, and the Mitogen Activated Protein Kinase (MAPK) signaling pathway. Conclusions This study may identify the novel non-invasive biomarkers for ICP and provided new insights into the important role of the exosome miRNA regulation in ICP.

Abstract
Objective To establish pregnancy‐specific reference ranges for fasting and postprandial total serum bile acid (TSBA) concentrations. Design Cross‐sectional study. Setting Tertiary‐care university hospital. Population Healthy pregnant women at term admitted to the Obstetrics Department over a period of 1 year. Exclusion criteria were an established diagnosis of intrahepatic cholestasis of pregnancy (ICP) or any coexisting condition of increased risk for ICP. Methods Both fasting (after 8–14 h of fasting) and postprandial (2 h after meal) TSBA concentrations were measured in 612 women (with 528 fasting samples and 377 postprandial samples) by automated enzymatic spectrophotometric assay. Main outcome measures Fasting and postprandial TSBA concentrations in 612 women. Results Reference intervals of 4.4–14.1 μmol/L for fasting TSBA and 4.7–20.2 μmol/L for postprandial TSBA were established. The postprandial values were significantly higher than the fasting values, with a median increase of 1.0 μmol/L (p < 0.0001). A correlation between fasting TSBA concentrations and postprandial concentrations was found, as well as correlations with fetal sex, parity and assisted reproductive technologies. A seasonal pattern was noticed for both fasting and postprandial TSBA, with the highest values measured in the winter season (p < 0.01 and 0.02, respectively) Conclusions Normal pregnancy is associated with mild hypercholanaemia, and therefore a higher threshold should be considered for the diagnosis of ICP. We suggest using the upper reference limits observed in our healthy pregnant population (14 μmol/L for fasting TSBA and 20 μmol/L for postprandial TSBA). As the fasting measurement is more specific for the diagnosis, and the postprandial measurement is essential for the assessment of severity, it is recommended to measure both values rather than use random sampling. Tweetable abstract Normal pregnancy is associated with mild hypercholanaemia, a higher threshold should be considered for the diagnosis of ICP. Normal pregnancy is associated with mild hypercholanaemia, a higher threshold should be considered for the diagnosis of ICP.

BMC Pregnancy Childbirth 2022; 22:269.

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
Liver disorders specific to pregnancy are rare but can have potentially serious consequences for mother and fetus. Pregnancy-related liver disorders are the most common cause of liver disease in otherwise healthy pregnant women and pose a challenge to physicians because of the need to take into account both maternal and fetal health. A good knowledge of these disorders is necessary as prompt diagnosis and appropriate management results in improved maternal and fetal outcomes. This review will focus on pregnancy-specific disorders and will aim to serve as a guide for physicians in their diagnosis, management and subsequent monitoring.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) is characterized by increased serum bile acid levels in the third trimester of pregnancy and resolves quickly after delivery. Here, we present the case of a 29-year-old woman who developed idiopathic liver damage during puberty, and subsequently ICP and severe pruritus during two pregnancies. DNA sequencing revealed a heterozygous deletion (c.393_delG) in the fibroblast growth factor receptor 4 (FGRF4) gene causing a premature stop codon. The resulting FGFR4 haploinsufficiency is likely to impede the enterohepatic feedback repression of hepatic bile acid synthesis via FXR and FGF19. It represents a new genetic etiology of ICP.

Bile acid metabolism and FXR-mediated effects in human cholestatic liver disorders. Biochem Soc Trans 2022; 50:361-373. [PMID: 35191955 DOI: 10.1042/bst20210658] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2021] [Revised: 01/28/2022] [Accepted: 02/07/2022] [Indexed: 02/06/2023]
Abstract
Intrahepatic cholestasis is the main feature of a group of liver diseases that are characterized by hepatic and systemic accumulation of bile acids due to impaired excretion of bile, based on inflammation of intrahepatic and extrahepatic bile ducts or dysfunction of hepatobiliary transport proteins. The nuclear bile acid sensor farnesoid X receptor (FXR) is central for the regulation of bile acid turnover, including synthesis, hepatic excretion and intestinal and hepatic uptake. Several drugs targeting FXR have been developed for the treatment of cholestatic liver diseases, and so far one of them has been granted conditional approval. In this review, we will discuss the current knowledge and the clinical and experimental data available on agents affecting FXR and bile acid turnover.

Abstract
Primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) are two types of chronic cholestatic liver disease (CCLD). Little is known regarding the relationship between these conditions and pregnancy. We performed a systematic review and meta-analysis regarding the maternal and fetal outcomes amongst patients with a known diagnosis of PBC and PSC undergoing pregnancy. Our analysis shows that patients with PBC and PSC who undergo pregnancy are at an increased risk of pre-term delivery, as well as the development of new or worsening pruritus during pregnancy. Additionally, patients with PBC are at higher risk of undergoing a biochemical disease flare during the postpartum period compared to during pregnancy. However, there were no documented cases of maternal mortality or development of decompensated cirrhosis during pregnancy or the postpartum period.

Abstract
The objective of this study was to assess the value of serum leptin, adiponectin, apelin, and ghrelin as biomarkers for the prediction and diagnosis of intra-hepatic cholestasis (ICP). This prospective study included pregnant women in the third trimester of pregnancy: 63 with ICP, 48 and 15 of whom had mild and severe disease, respectively, and 32 as controls. ICP women had increased median levels of serum leptin, adiponectin, apelin, and ghrelin compared to the controls (p < 0.05). These biomarkers meaningfully changed regarding the severity of ICP: While leptin was reduced, apelin and ghrelin were increased, and adiponectin was increased somewhat. To predict and diagnose ICP, the predictive values of serum leptin, adiponectin, and apelin need to be accepted as comparable, with moderate to high sensitivity and specificity; however, the predictive value of serum ghrelin was somewhat lower. More research is needed to clarify the potential properties of adipokines to gain acceptance as a predictive or diagnostic biomarker for ICP.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) has an increased predisposition to occur in the third trimester of pregnancy and has a varied population incidence rates due to genetic influences. Owing to the adverse and unpredictable fetal outcomes, it poses a serious therapeutic challenge to the clinician. A rise in the incidence of iatrogenic prematurity has been observed, raising concerns over the perinatal outcomes. Excess bile acids and altered placental transport mechanisms have been strongly implicated in the pathogenesis of ICP and its complications. The exact etiology is not known; yet major underlying risk factors that are thought to contribute to the disease process include genetic, environmental, hormonal, and immunological. Newer molecular processes acting at the placental level, apart from specific histopathological changes, have assumed significance in recent times. In this review, we attempt to highlight the recent understanding of the mechanisms that operate in the placenta in patients with obstetric cholestasis that lead to poor fetal outcomes, through various studies published in the literature. Despite these additions to the existing knowledge on the etiopathogenesis of obstetric cholestasis and its possible placental origin, further studies are needed to validate the newer concepts.

Abstract
Intrahepatic cholestasis in pregnancy (ICP) represents, depending on its severity, a serious risk for the fetus. Those cases with unusually high bile acid levels may be resistant to pharmaceutical treatment and can be treated with plasma exchange or albumin dialysis. However, the success rate of these therapeutic options and the factors influencing therapeutic response are unknown. Furthermore, if these options fail to improve ICP and serum bile acid levels are very high (>200 μm/L), there are no clear recommendations when delivery should be planned. Here, we report a patient with severe ICP resistant to both therapeutic plasma exchange and albumin dialysis. Caesarean section was performed at 32 weeks of gestation followed by rapid remission of ICP.

Abstract
OBJECTIVE AND AIMS Serum total bile acid (TBA) level as the main index for the diagnosis of intrahepatic cholestasis of pregnancy (ICP) has some limitations. The early diagnosis and new treatment of ICP still need to be further strengthened. MATERIALS AND METHODS Plasma samples were collected, and exosomes were isolated. Key differential proteins were screened by bioinformatics methods. ELISA method was used to detect the concentration of the key differential protein in plasma samples, and the receiver operating characteristic curve (ROC) curve was drawn to find out the best critical value. RESULTS There were 138 differentially expressed proteins between the ICP and the normal groups by quantitative analysis. Cluster protein (CLU) was screened as a clinical validation index. The CLU concentration of plasma exosomes in the ICP group was significantly higher than that in the normal group (p < .0001). ROC curve analysis showed that the best critical point for diagnosing ICP according to the plasma exosomes CLU concentration of pregnant women was 255.28 ng/ml. In the ICP group, the best crucial point for predicting ICP with premature delivery is 286.72 ng/ml. CONCLUSIONS The plasma exosomes CLU in pregnant women with ICP is an important biomarker for clinical diagnosis and prediction of premature delivery of ICP.

Abstract
Background: High bile acid concentration is associated with adverse perinatal outcomes (i.e., stillbirth and preterm birth) and experimental studies indicate that thyroid hormone regulates bile acid metabolism, but this has not yet been translated to clinical data in pregnant women. We aim to explore the association of thyroid function with bile acid concentrations and the risk of gestational hypercholanemia. Methods: This study comprised 68,016 singleton pregnancies without known thyroid or hepatobiliary diseases before pregnancy and thyroid medication based on a prospective cohort. Thyroid function and serum total bile acid (TBA) were routinely screened in both early (9-13 weeks) and late pregnancy (32-36 weeks). Hypercholanemia was defined as serum TBA concentration ≥10 μmol/L. Multiple linear regression models and multiple logistic regression models were performed. Results: A higher free thyroxine (fT4) during both early or late pregnancy was associated with a higher TBA concentration and a higher risk of hypercholanemia (all p < 0.01). A higher thyrotropin (TSH) in early pregnancy was associated with a higher TBA concentration in early pregnancy (p = 0.0155), but with a lower TBA concentration during later pregnancy (p < 0.0001), and there was no association of TSH with hypercholanemia. Overt hyperthyroidism in late pregnancy was associated with a 2.12-fold higher risk of hypercholanemia ([confidence interval; CI 1.12-4.03], p = 0.021) and subclinical hyperthyroidism during later pregnancy was associated with a 1.5-fold higher risk of hypercholanemia ([CI 1.14-1.97], p = 0.0034). Sensitivity analyses indicated that a high fT4 throughout pregnancy was associated with a higher risk of hypercholanemia rather than only in early or late pregnancy. Conclusions: A higher fT4 concentration during either early or late pregnancy, but not the TSH concentration, is associated with higher TBA and a higher risk of gestational hypercholanemia. Furthermore, hyperthyroidism during pregnancy could be a novel risk factor for hypercholanemia.

Abstract
AIM A retrospective study of the occurrence of liver damage and obstetric outcomes in pregnant women diagnosed with pruritus. METHODS The following parameters were monitored in patients: aspartate aminotransferase (AST), alanine aminotransferase, gamma-glutamyl transferase, bilirubin (direct and total), hemoglobin, platelets, serum bile acid level, age of pregnant women, parity, pregnancy weight gain, birth weight, and gestational age at delivery. A total of 107 patients were included during a five-year period (2016-2020) and classified into three groups. Group A included 17 pregnant women with pruritus without elevated liver enzymes and bilirubin. Group B included 50 pregnant women with pruritus, elevated liver enzymes, and bilirubin. Group C included 40 pregnant women with pruritus and elevated bile acids (regardless of liver enzyme levels). RESULTS The groups did not significantly differ in patients' age and parity, but there was a statistically significant between-group difference in weight gain during pregnancy. The values of AST, ALT, GGT, LDH, and direct bilirubin were the highest in group B, and serum bile acids were expectedly the highest in group C. There was no statistically significant variation in the onset of labor and mode of delivery between groups. However, groups significantly differed in gestational age at delivery, newborn birthweight, and pregnancy prolongation from the onset of pruritus to delivery. CONCLUSION Further study is needed to assess the pathophysiologic mechanisms underlying intrahepatic cholestasis of pregnancy as well as any significant liver damage associated with pregnancy.

Abstract
Intrahepatic cholestasis of pregnancy commonly presents in the second and third trimester with unexplained pruritus sine materia, abnormal liver function tests, and/or elevated serum total bile acid concentration. Its incidence ranges from less than 1% to 27.6%, with Araucana Indians from Chile being the highest affected. Intrahepatic cholestasis of pregnancy complicates pregnancy, hence influencing its outcomes. Our series involves three cases of pruritus in pregnancy ending with one elective cesarean delivery and two emergency cesarean deliveries without any significant complications to babies as well as immediate resolution of maternal symptoms. High index of suspicion for intrahepatic cholestasis of pregnancy is of paramount importance among clinicians even in primary care setup. Prompt treatment and intervention will prevent poor perinatal outcome.

Abstract
OBJECTIVE To study the effect of using ursodeoxycholic acid (UDCA) to treat monochorionic and dichorionic twin pregnancies complicated by intrahepatic cholestasis of pregnancy (ICP) and to examine the differences in perinatal outcomes. METHODS A total of 406 twin-carrying pregnant women who had ICP and received care at West China Second Hospital, Sichuan University between January 1, 2015 and November 1, 2018 were included in the study. The clinical data of monochorionic diamniotic (MCDA) and dichorionic diamniotic (DCDA) twins with ICP were analyzed. Analysis was done to compare the treatment effect for lowering serum total bile acid (TBA) and the perinatal outcomes with simple UDCA medication or combination medication. RESULTS There were no statistically significant differences in TBA levels, early-onset ICP, simple UDCA medication or combination medication, neonatal Apgar score, birth weight, length of hospital stay, C-section rate, and perinatal mortality between the MCDA and the DCDA twin groups with ICP. However, maternal age, BMI, scarred uterus, in vitro fertilization-embryo transfer, preeclampsia, twin comorbidity rate of the two groups showed statistical differences. Further comparison between twin pregnancies with mildly-elevated TBA and those with severely-elevated TBA showed significant difference in preterm birth rate ( P<0.05). CONCLUSION Simple UDCA medication or combination medication may have the same therapeutic effect on MCDA and DCDA twin pregnancies with ICP. Monochorionic twin pregnancy, twin comorbidities and pregnancy complications were still important factors affecting pregnancy outcomes of twin pregnancies with ICP. Twin pregnancies with slightly elevated TBA have been managed as severe ICP, which may be associated with increased iatrogenic preterm births.

Abstract
Intrahepatic cholestasis of pregnancy (ICP), the most common liver disorder of pregnancy, is associated with complications for both a pregnant person and their fetus. The underlying cause is not well understood. The pruritus associated with ICP is uncomfortable for pregnant people; however, the primary concern is the fetal risk. Fetal risks include preterm labor and birth and intrauterine fetal demise. This is particularly significant for certain populations because of the disparities in incidence of ICP; in the United States, it disproportionately affects Latinx people, the largest and fastest‐growing minority population. Diagnosis, monitoring, and treatment of ICP are vital to reduce discomfort from pruritis and avoid potential fetal demise. However, diagnosis and treatment are complicated by the lack of definitive diagnostic criteria, the frequent delay in laboratory analysis, and the cost of treatment. This case report aims to improve midwives’ familiarity with ICP and discusses the epidemiology, risk factors, presentation, diagnostic criteria, and available management strategies for this disease as well as the importance of anticipatory guidance regarding increased lifetime risk of ICP in future pregnancies and hepatobiliary disease. Additionally, it discusses the challenges involved in diagnosis and access to treatment. Prompt diagnosis and initiation of treatment may reduce fetal morbidity and mortality.

Abstract
OBJECTIVE To explore the cytochrome P450 family 27 subfamily A member 1 (CYP27A1) gene mutations in Chinese women with intrahepatic cholestasis of pregnancy (ICP) and the correlation between CYP27A gene mutations and BA (bile acid) level changes. METHODS In this study, the entire coding region of the CYP27A1 gene was sequenced in 151 Han Chinese women with ICP and 1029 matched samples, and the pathogenicity of identified CYP27A1 gene mutations was judged through evolutionary conservation analysis, computational analysis and protein structure modeling. Finally, we verified the relationship between gene mutations and total serum bile acid (TBA) and cholesterol (CHOL) levels through experiments in cell culture. RESULTS We identified five heterozygous CYP27A1 missense mutations in five ICP samples. Three online tools, Polyphen-2, MutationTaster and SIFT, predicted that the five CYP27A1 mutations were pathogenic. Furthermore, all five mutations caused marked protein structural changes. Experiments in cells showed that the intracellular and medium levels of TBA in the mutant groups were lower than those in the wild-type group, while the CHOL levels were higher in all mutants except for the R158H mutant. CONCLUSIONS CYP27A1 mutations are associated with the levels of TBA and CHOL, suggesting that CYP27A1 mutations contribute to abnormal total cholesterol and BA levels, which leads to ICP.

Abstract
AIM To identify the incidence of Obstetric Cholestasis in a Maternity unit. To compare our investigation, criteria for diagnosis and management plan with National Guidelines. To assess adverse maternal and neonatal outcomes associated with this condition. METHOD Serum Bile Acid requests are sent to an external laboratory, Biomnis in Dublin, for processing. A log of 2018 requests was obtained from Biochemistry. The pregnant patients with values > 8 mmol/L were selected. A data collection proforma was designed and retrospective chart review performed. RESULTS Of the 1302 births in SUH in 2018, 42 women met the criteria resulting in a suspected incidence of 3.2% (n = 42). 9.5%(n = 4) of patients had a history of OC in a previous pregnancy. Bile acid values ranged from 8.1 to 124 mmol/L. LFTs were deranged in 81% (n = 34) of patients. Gestation at delivery ranged from 35 weeks to 40 + 9. OC alone was the indication for induction in 57%9n = 24). CS in 43% (n = 20) and Vaginal birth in 57% (n = 25). Neonatal outcome: 7% (n = 3) reduced APGAR, 7% (n = 3) passed meconium, 9% (n = 4) NICU admission, no stillbirths. CONCLUSION Suspected incidence of 3.2% (n = 42) is significantly higher than the stated 0.7% across multi-ethnic populations. Greater congruence is required on the BA cut off value for diagnosis as there is no specified value in guidelines. While we may be over diagnosing patients based on BA level, we are also undertreating them, with 55% (n = 23) receiving Ursofalc. There was no neonatal mortality.

Abstract
Induction of labour (IoL) is generally conducted when maternal and foetal risks of remaining pregnant outweigh the risks of delivery. With emerging literature around non-medically indicated IoL, contemporary clinical practice has seen an increase in IoL at 39 weeks' gestation. This review highlights recent evidence on the most common indications for IoL including gestational diabetes, hypertensive disorders of pregnancy, intrahepatic cholestasis of pregnancy, and post-term pregnancies. It also summarizes the evidence related to the timing of IoL for other common conditions based on recent literature reviews.
