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.

Intrahepatic Cholestasis of Pregnancy and Associated Adverse Maternal and Fetal Outcomes: A Retrospective Case-Control Study. Gastroenterol Res Pract 2021; 2021:6641023. [PMID: 33833795 PMCID: PMC8016576 DOI: 10.1155/2021/6641023] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Revised: 02/02/2021] [Accepted: 03/10/2021] [Indexed: 12/11/2022] Open
Abstract
Objective Intrahepatic cholestasis of pregnancy (ICP) is a common pregnancy-related liver disease and is associated with an increased risk of adverse neonatal outcomes. Ursodeoxycholic acid (UDCA) is the most effective treatment. This study was aimed at investigating the adverse outcomes of ICP and evaluating the effects of treatment with UDCA in patients with ICP. Methods We included 114 women with ICP and 3725 women without ICP (no-ICP group) who delivered in our hospital between September 2017 and August 2019. The prevalence of ICP in this study was 3.15%. We matched each woman with ICP to five controls. Of all the 114 women with ICP, 73 (64.04%) received UDCA while 41 (35.96%) did not. Logistic multivariate regression analysis was used to compare the adverse outcomes between those with ICP and matched controls as well as between those who received UDCA (UDCA group) and those who did not (non-UDCA group). Results Compared with controls, women with ICP were more likely to have preeclampsia (adjusted odds ratio, aOR = 16.74, 95% CI 5.29-52.98), cesarean section (aOR = 1.76, 95% CI 1.10-2.81), and preterm birth (aOR = 24.35, 95% CI 2.74-216.67). Administration of UDCA reduced the rate of preterm birth (1.37% vs. 14.63%, aOR = 0.10, 95% CI 0.01-0.90). Conclusion ICP increased the risk of preeclampsia, cesarean section, and preterm birth. UDCA could reduce the rate of preterm birth.

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

Abstract
Objective Some components of the routine complete blood count (CBC) and their ratios, such as neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been found to be sensitive biomarkers of preeclampsia and other inflammatory obstetric conditions. We wanted to evaluate whether they can be associated with intrahepatic cholestasis of pregnancy (ICP). Materials and Methods We conducted a retrospective case-control study between May 1, 2015 and July 1, 2018. Cases were considered pregnancies with ICP and control healthy pregnancies. Cases and controls were matched for age, parity, and race. We compared the levels of white blood cells (WBC), hemoglobin, neutrophils, lymphocytes, NLR, PLR, platelets, red cell distribution width (RDW), and mean platelet volume (MPV) in the first and third trimesters between cases and controls. In addition, we compared the same components in the third trimester between patients with mild (serum total bile acid (TBA) of 10 - 40 µmols/L) and severe (TBA > 40 µmols/L) ICP. Results There were 33 patients with ICP and 33 controls. There were no significant differences between the two groups in the first trimester. WBC, neutrophil count, and NLR were decreased in women with ICP in the third trimester compared to controls. MPV was significantly higher in the third trimester of patients with ICP compared to controls. RDW was lower in mild ICP compared to severe ICP in the third trimester. Conclusion Decreased WBC, neutrophil, NLR, and MPV values are associated with ICP and may be useful additions to the diagnostic algorithm for ICP. Larger studies are needed to assess the responsible underlying molecular pathogenic mechanisms.

Abstract
Studies on the risk factors for intrahepatic cholestasis of pregnancy (ICP) in a population-based cohort are lacking. We assess the prevalence and risk factors of ICP in a Chinese population. In this study, a cohort study was conducted that included 12,200 eligible pregnant women. The overall incidence of ICP in this cohort was 6.06%. With increasing maternal age, the incidence of ICP decreased in women younger than 30 years of age but increased in those older than 30. With increasing pre-pregnancy BMI, the incidence of ICP decreased if the pre-pregnancy BMI was less than 23 kg/m2 but increased if it was 23 kg/m2 or higher. Further analysis showed that the risk of ICP increased when maternal age was < 25 years (Adjusted RR 2.01; 95% CI 1.64–2.47) or ≥ 35 years (Adjusted RR 1.34; 95% CI 1.02–1.76). Furthermore, an increased risk of ICP was associated with pre-pregnancy underweight (adjusted RR 1.27; 95% CI 1.04–1.56), inadequate gestational weight gain (GWG) (adjusted RR 1.58; 95% CI 1.28–1.96), lower maternal education (adjusted RR 2.96; 95% CI 2.35–3.74), multiparity (adjusted RR 1.54; 95% CI 1.23–1.93), and twin/multiple pregnancies (adjusted RR 2.12; 95% CI 1.25–3.58). Maternal age (< 25 or ≥ 35 years), underweight, inadequate GWG, lower maternal education, multiparity, and twin/multiple pregnancies were identified as risk factors of ICP.

Whole-exome sequencing reveals ANO8 as a genetic risk factor for intrahepatic cholestasis of pregnancy. BMC Pregnancy Childbirth 2020; 20:544. [PMID: 32942997 PMCID: PMC7499841 DOI: 10.1186/s12884-020-03240-z] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2020] [Accepted: 09/08/2020] [Indexed: 12/13/2022] Open
Abstract
Background Intrahepatic cholestasis of pregnancy (ICP) is characterized by pruritus and cholestasis in late pregnancy and results in adverse pregnancy outcomes, including preterm delivery and birth weight, which are affected by the genetic and environmental background. However, until now, the genetic architecture of ICP has remained largely unclear. Methods Twenty-six clinical data points were recorded for 151 Chinese ICP patients. The data generated from whole-exome sequencing (WES) using the BGISEQ-500 platform were further analyzed by Burrows-Wheeler Aligner (BWA) software, Genome Analysis Toolkit (GATK), ANNOVAR tool, etc. R packages were used to conduct t-test, Fisher’s test and receiver operating characteristic (ROC) curve analyses. Results We identified eighteen possible pathogenic loci associated with ICP disease in known genes, covering ABCB4, ABCB11, ATP8B1 and TJP2. The loci Lys386Gln, Gly527Gln and Trp708Ter in ABCB4, Leu589Met, Gln605Pro and Gln1194Ter in ABCB11, and Arg189Ser in TJP2 were novel discoveries. In addition, WES analysis indicated that the gene ANO8 involved in the transport of bile salts is newly identified as associated with ICP. The functional network of the ANO8 gene confirmed this finding. ANO8 contained 8 rare missense mutations that were found in eight patients among the 151 cases and were absent from 1029 controls. Out of the eight SNPs, 3 were known, and the remaining five are newly identified. These variants have a low frequency, ranging from 0.000008 to 0.00001 in the ExAC, gnomAD – Genomes and TOPMED databases. Bioinformatics analysis showed that the sites and their corresponding amino acids were both highly conserved among vertebrates. Moreover, the influences of all the mutations on protein function were predicted to be damaging by the SIFT tool. Combining clinical data, it was found that the mutation group (93.36 µmol/L) had significantly (P = 0.038) higher total bile acid (TBA) levels than the wild-type group (40.81 µmol/L). Conclusions To the best of our knowledge, this is the first study to employ WES technology to detect genetic loci for ICP. Our results provide new insights into the genetic basis of ICP and will benefit the final identification of the underlying mutations.

Abstract
OBJECTIVE To evaluate the benefit of performing a screening for differential diagnoses by hepatobiliary ultrasound and viral serologies, in case of suspected intrahepatic cholestasis of pregnancy (ICP). METHODS Retrospective single-center study in a tertiary maternity unit, including all women with a suspected ICP between January 2012 and September 2018. The primary outcome was the differential diagnosis rate obtained through initial screening. We described women characteristics, symptoms, and blood results that led to ICP suspicion. We evaluated the rate of differential diagnosis established by the initial screening. We described the population of women presenting with an ICP differential diagnosis. RESULTS The study included 254 women. Prevalence of differential diagnosis was 2 %. ICP was suspected in more than 50 % of cases in third trimester of pregnancy (79.5 %). Women presented with pruritus in 90.9 % of cases. Bile acid levels were between 20 and 40 μmol/L in 56.3 % of cases and above 40 μmol/L in 12.2 % of cases. The screening to rule out differential diagnosis of ICP was performed in half of the cases. When performed, the screening did not lead to the diagnosis of any differential disease. CONCLUSION In this cohort, among the 254 women, one (0.4 %) would have been wrongly diagnosed with ICP if the initial screening for differential diagnosis had not been performed. Screening for differential diagnosis does not seem to provide any benefit regarding the management of suspected ICP and could therefore only be performed in case of atypical clinical presentation of ICP, resistance to treatment or persisting abnormal liver function tests in the postpartum period.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) is the most common hepatic disorder related to pregnancy in women. It usually develops within the third trimester of pregnancy and presents with pruritus as well as elevated levels of bile acid and/or alanine aminotransferase. Clinical signs quickly resolve after delivery; however, there is a high risk of the disorder recurring in subsequent pregnancies. ICP is associated with an increased risk of perinatal complications (premature birth, respiratory disorders, even stillbirth). Elevated levels of gestational hormones and genetic predispositions are important factors for the development of ICP; among the latter, mutations in hepatobiliary transport proteins (multidrug resistance protein 3-MDR3, bile salt export pump- BSEP) play a major role. Clinical and biochemical symptoms of ICP include pruritus and increased levels of total bile acids (TBA). Serum levels of TBA should be monitored in ICP patients throughout the pregnancy as concentrations above 40 μmol/L, which define that severe ICP isassociated with an increased risk of fetal complications. Therapeutic management is aimed at reducing the clinical symptoms, normalizing maternal biochemistry and preventing complications to the fetus. Pharmacological treatment of intrahepatic cholestasis of pregnancy consists of the administration of ursodeoxycholic acid to lower the levels of TBA and possibly reduce pruritus. If the treatment fails, premature delivery should be considered.

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

Abstract
Background: Intrahepatic cholestasis of pregnancy (ICP) is characterized by the elevation of total bile acids (TBAs). The primary concern in women with ICP is the increased risk of stillbirth. ICP is generally considered as "mild" when TBA levels range from 10 to 39 µmol/L and "severe" with levels greater than 40 µmol/L, although levels of TBA ≥100 µmol/L have been also considered as a further threshold of severity.Objective: To quantify the association between different severities of ICP (TBA 10-39, 40-99, and ≥100 µmol/L) and perinatal death.Data sources: Medline, Embase, Scopus, Web of Sciences, and ClinicalTrial.gov were searched from the inception of each database to February 2019.Methods of study selection: Randomized, cohort, case-control, or case series studies reporting maternal and perinatal outcomes on women with ICP by the three prespecified TBA levels (10-39, 40-99, and ≥100 µmol/L) were included. We excluded multiple gestations and trials which included an intervention. The analysis was performed with Pearson chi-square and Fisher's exact test as appropriate. Continuous outcomes were compared using metaregression with inverse variance weighting using reported sample sizes and standard deviations. Pairwise comparisons used a Bonferroni correction to control for multiple testing.Tabulation, integration, and results: Six articles including 1280 singleton pregnancies affected by ICP were included in the systematic review. Out of the 1280 singleton pregnancies affected by ICP included, 118 had ICP with TBA ≥100 µmol/L. Perinatal death was more common in women with TBA ≥100 µmol/L (0.4% for TBA 10-39 μmol/L versus 0.3% for TBA 40-99 μmol/L versus 6.8% for TBA ≥ 100 μmol/L, p < .0001). Of the 8 perinatal deaths in the TBA ≥100 µmol/L group, 3 occurred ≥34 weeks. TBA ≥100 µmol/L increased the risk of spontaneous preterm birth (PTB) (5.4% versus 8.6% versus 18.2% respectively, p < .0001) and iatrogenic PTB (10.8% versus 21.6% versus 35.8% respectively, p<.0001) as well as meconium-stained amniotic fluid (9.0% versus 18.4% versus 31.6% respectively, p < .0001).Conclusions: Maternal TBA ≥100 µmol/L is associated with a 6.8% incidence of perinatal death, most of which (5.9% overall) are stillbirths, while TBA <100 µmol/L are associated with an incidence of perinatal death of 0.3%. It may be reasonable to consider late preterm delivery (at about 35-36 weeks) in women with TBA ≥100 µmol/L.

Abstract
Aim of the study The optimum management method and the best time of delivery still remain unclear for intrahepatic cholestasis of pregnancy (ICP). We aimed to ascertain whether there is a benefit of close monitoring at hospital. Material and methods We evaluated the maternal and neonatal records of ICPs over a recent five-year period. A total of 35 women and their 38 newborns were analyzed. The impact of hospitalization was evaluated in terms of delivery type, labor induction, preterm delivery, Apgar scores, and neonatal intensive care unit admission. Results The median maternal age was 30.7 years, and median gestation at diagnosis was 34 weeks. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were normal in three patients; 32 (91.4%) women had at least one increased hepatic enzyme level. The median AST level was elevated to 66 U/l (almost two-fold), and the median ALT level was 91 U/l (about three-fold). The median gestation time at delivery was 37 weeks. The preterm delivery rate was 45.7%. The median birth weight was 3020 g, and median Apgar scores were 9 and 10 at the 1st and 5th minutes, respectively. Neonatal intensive care unit admission occurred in 21 neonates (55.3%). During pregnancy follow-up, 22 women (62.8%) were hospitalized during their pregnancies. There was no statistically significant difference between groups in terms of obstetric and perinatal outcomes (p > 0.05). However, the hospitalized pregnant women were found to have higher levels of serum transaminases (p = 0.15 and p = 0.01 for ALT and AST, respectively). Conclusions Hospitalization may be helpful in some ICP cases, especially when enzyme levels are elevated.

Abstract
In nearly 50% of patients with drug-induced liver injury, the bile flow is impaired known as cholestasis. Intrahepatic cholestasis of pregnancy (ICP) is the most common liver disease that happens in pregnancy. Some of the clinical symptoms include pruritus, dark urine, and abnormal liver function tests. A rise of serum bile acids is the most accurate diagnostic evidence. ICP may lead to premature birth, fetal distress, and even postpartum hemorrhage or stillbirth in some severe cases. Higher bile acid levels (> 40 μmol/L) are associated with higher rates of adverse fetal outcomes. Due to the multifactorial nature of ICP, its etiology is still not fully understood. Therefore, the current treatments of ICP are limited to control symptoms and protect fetuses. Among various causing factors, drug exposure during pregnancy is one common factor, and it can be prevented if we know drugs with increasing risk of cholestasis. Here we analyzed over 9.5 million FDA adverse effect reports to identify drugs with increasing risks of cholestasis as an adverse effect. Patients treated for cholestasis or liver diseases were removed. The odds ratio analysis reveals that lansoprazole (LSPZ), omeprazole (OMPZ) and amoxicillin (AMXC) are associated with an increased risk of cholestasis. LSPZ is associated with increased reported cholestasis by a factor of 2.32 (OR with 95% confidence interval [2.21, 2.43]). OMPZ is associated with increased reported cholestasis by a factor of 2.61 [2.54, 2.69]. AMXC is associated with increased reported cholestasis adverse effect by a factor of 6.79 [6.49, 7.11]. The risk of cholestasis associated with these three drugs is further increased in pregnant women. These findings justify careful reassessment of the safety of the three identified drugs.

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

Abstract
Importance Intrahepatic cholestasis of pregnancy (ICP) complicates approximately 0.2% to 2% of pregnancies and can lead to increased fetal risks in pregnancy. Objective This review aims to increase the knowledge of women's health care providers regarding the diagnosis, management, and fetal risks associated with ICP. Results The diagnosis of ICP is based on symptoms of pruritus that typically include the palms and soles, as well as elevated bile acid levels. Other liver function tests such as alanine aminotransferase and aspartate aminotransferase are also frequently elevated, and other causes of liver dysfunction should be ruled out. Fetal risks of ICP include increased risk of preterm birth, meconium-stained amniotic fluid, respiratory distress syndrome, or stillbirth. There is evidence that as bile acid levels increase, so does the risk of adverse neonatal outcomes. Ursodeoxycholic acid treatment has been shown to improve maternal pruritus symptoms, as well as biochemical tests, but no treatment has been shown to definitively improve fetal outcomes. Conclusions and Relevance Providers should be aware of the signs and symptoms of ICP and provide accurate diagnosis and management of affected women. Women with a diagnosis of ICP should be treated with ursodeoxycholic acid to improve maternal symptoms. Given the increased risk of stillbirth in the setting of ICP, delivery may be considered at 37 weeks' gestation.

Abstract
BACKGROUND The primary aim of the study is to investigate the perinatal outcomes in intrahepatic cholestasis of pregnancy (ICP) with monochorionic diamniotic (MCDA) twin pregnancy. METHODS This study is a retrospective observational study for women with ICP and MCDA twin pregnancy. Included cases were divided into mild ICP group (10-39 mmol/L) and severe ICP group (> = 40 mmol/L), whose perinatal outcomes were compared between this two groups and whose predictors of adverse perinatal outcomes were evaluated. RESULTS 37 cases and 21 cases are in mild and severe ICP group respectively, of which, the incidence of gestational diabetes mellitus (GDM) and iatrogenic preterm delivery in severe ICP group are higher than those in mild ICP group. Gestational age (GA) at diagnosis of ICP < 32 weeks is an independent risk factor for GA at delivery < 35 weeks and for composite adverse neonatal outcome. Total bile acids (TBA) > 40 mmol/l is an independent risk factor for meconium-stained amniotic fluid. CONCLUSION For women with ICP and MCDA twin pregnancy, GA at diagnosis of ICP < 32 weeks and TBA > 40umol/L are associated with adverse perinatal outcomes.

Abstract
BACKGROUND The aim of this study was to determine whether intrahepatic cholestasis of pregnancy (ICP) is associated with causes of death during on average 35 years follow-up after the delivery. METHODS The study population comprised 571 women with ICP in at least one pregnancy seen at Tampere University Hospital, Finland, between 1969 and 1988. ICP was verified from patient records. The previous and following subjects in the maternity ward diary were taken as controls for each ICP case. In total, there were 1333 controls. All underlying causes of death were obtained from Statistics Finland in March 2017. The deaths occurred during 1971-2015 and the causes of death were classified according to ICD-10. RESULTS Altogether, 39 of the mothers with ICP (6.8%) and 111 of the controls (8.3%) had died by the end of 2015 (p = 0.267). There were more underlying causes of death from gastrointestinal diseases (15%) in the ICP group than in the control group (4%) (p = 0.011). The number of underlying causes of death due to diseases of the circulatory system were lower in the ICP group (13%) than in the control group (26%), although the finding was not statistically significant (p = 0.088). Moreover, neoplasms were the underlying cause of death in 46% of cases among mothers with ICP and in 41% of cases among the controls (p = 0.609). Diseases of the other organ systems were rare in both groups. CONCLUSION Women with a history of ICP do not have an increased overall mortality. However, deaths from gastrointestinal diseases are overrepresented among women with a history of ICP.

Abstract
Objective: To investigate the association of inflammatory markers with severity of intrahepatic cholestasis of pregnancy (ICP). Materials and Methods: This retrospective case-control study was conducted with 229 pregnant women, 84 with ICP, and 145 age-matched healthy pregnant women. Patients were categorized as mild ICP (<40 µmol/L) and severe ICP (≥40 µmol/L) with regard to serum bile acids. Inflammatory markers (neutrophil-to-lymphocyte ratio (NLR), platelet-to- lymphocyte ratio (PLR) and mean platelet volume (MPV), and red blood cell distribution width (RDW) were compared between the groups. Results: Patients with ICP had significantly decreased RDW and increased white blood cell counts (WBC), MPV and PLR, but no significant changes in NLR. The comparison of mild and severe cases with regard to NLR, PLR, WBC, and RDW was similar (p>0.05). MPV levels were significantly increased in severe group (p<0.05). Conclusion: WBC, MPV, and PLR were the inflammatory markers significantly increased, and RDW was signifantly reduced in ICP. MPV was the marker that significantly increased with the severity of disease. The use of inflammatory markers in the assessment of perinatal outcomes needs further studies.

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

A retrospective cohort review of intrahepatic cholestasis of pregnancy in a South Australian population. Eur J Obstet Gynecol Reprod Biol 2017; 218:33-38. [PMID: 28926728 DOI: 10.1016/j.ejogrb.2017.09.012] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2017] [Revised: 08/26/2017] [Accepted: 09/13/2017] [Indexed: 12/27/2022]
Abstract
OBJECTIVE To review the management and outcomes of Intrahepatic Cholestasis of Pregnancy (ICP) in South Australia (SA) over the past decade. DESIGN Retrospective cohort review. SETTING Public clinics at two teaching hospitals in SA. POPULATION All pregnancies associated with ICP (defined as pruritus with serum bile acids≥10μmol/L) managed 2001-2010. METHODS Identification of subjects (laboratory database), detailed chart-review to ascertain demographics, maternal/perinatal outcomes and associated pregnancy comorbidities, analysis of mild/severe disease cohorts, comparison with normal population data, using Student's t-test or Mann-Whitney U test as appropriate for continuous variables, and Pearson's chi-square test or Fisher's exact test for categorical variables. Unadjusted odds ratios (OR) with 95% confidence intervals (95% CI) were calculated in comparison with the general pregnant population for clinically significant outcomes. RESULTS 320 women (359 pregnancies) were diagnosed with ICP over the 10-years: incidence 0.6%/year. Within the cohort, the incidences of gestational diabetes (12.5%; OR 3.06, 95% CI 2.23-4.18), pre-eclampsia (10.3%; OR 75.84, 95% CI 52.91-178.70), and spontaneous preterm labour (23.1%; OR 2.05, 95% CI 1.41-2.98) were much higher than in the general SA pregnant population. Pregnancies with severe ICP (serum bile acids≥40μmol/L) had ICP diagnosed earlier (231 vs 248 days, P<0.001), and ended earlier (256 vs 260 days, P<0.001) with lower birthweights (2827g vs 3093g, P <0.001) than those with mild ICP. Neonates of severe ICP mothers were more likely to require special-care-nursery admission, but perinatal complication rates did not differ. There were no stillbirths. CONCLUSION This large Australian retrospective cohort study confirms generally favourable outcomes associated with ICP, mild or severe, with no stillbirths, likely secondary to proactive medical management. A high proportion of pregnancies were also affected by gestational diabetes, pre-eclampsia, and/or spontaneous pre-term labour compared with the general population.

[PMID: 28691322 DOI: 10.1111/jog.13399] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2016] [Revised: 03/15/2017] [Accepted: 04/18/2017] [Indexed: 12/26/2022]
Abstract
AIM We aimed to determine the association between maternal total bile acid (TBA) levels and the risks of adverse perinatal outcomes in pregnant women with intrahepatic cholestasis of pregnancy (ICP) based on a meta-analysis study. METHODS We searched PubMed for articles published from 2000 to 2015 with a focus on ICP and restriction to the English language. The main perinatal outcomes were preterm birth (PTB), meconium-stained amniotic fluid (MSAF), asphyxia, or respiratory distress syndrome (RDS). Relative risk (RR) with 95% confidence intervals (CI) was the summary statistic. We used a random- or fixed-effects model to calculate the pooled RR according to the heterogeneity test. Subgroup analyses were performed by region and study design. RESULTS Nine eligible related citations fulfilled the inclusion criteria and were included in this study. Compared with pregnant women with a serum TBA < 40 μmol/L, severe ICP (TBA ≥ 40 μmol/L) was associated with a significantly increased risk of adverse fetal outcomes (pooled RR, 1.96; 95%CI, 1.63-2.35), PTB (pooled RR, 2.23; 95%CI, 1.51-3.29), MSAF (pooled RR, 2.27; 95%CI, 1.81-2.85), and asphyxia or RDS (pooled RR, 1.67; 95%CI, 1.18-2.36). Sensitivity analysis suggested that the study design difference may be a major source of heterogeneity. No publication bias was demonstrated by Begg's test (P > 0.05). CONCLUSION This meta-analysis indicates that maternal elevated bile acid levels are significantly associated with increased risks of overall adverse perinatal outcomes, PTB, MSAF, and asphyxia or RDS. Serum TBA levels seem to be a useful predictor for the risk of adverse perinatal outcomes.

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

Relationship between early onset severe intrahepatic cholestasis of pregnancy and higher risk of meconium-stained fluid. PLoS One 2017; 12:e0176504. [PMID: 28437442 PMCID: PMC5402936 DOI: 10.1371/journal.pone.0176504] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2017] [Accepted: 04/11/2017] [Indexed: 12/27/2022] Open
Abstract
Background Intrahepatic cholestasis of pregnancy (ICP) is the commonest gestational liver disease. The risk of adverse fetal outcome has been associated with the severity of maternal hypercholanemia after diagnosis. Objective To investigate whether there is a relationship between the severity and timing of onset of hypercholanemia and the risk of meconium-stained amniotic fluid (MSAF) and adverse neonatal events. Study design The study included 382 pregnancies complicated by ICP managed at a referral hospital in Buenos Aires (Argentina) between June 2009 and December 2013. The patients were classified into three groups according to the severity of hypercholanemia at diagnosis; mild (10–19.9 μmol/L), moderate (20–39.9 μmol/L) and severe (≥40 μmol/L). Their clinical characteristics and pregnancy outcomes were investigated in a prospective observational study. Results Higher risk of MSAF was observed when ICP appeared early in gestation or when hypercholanemia was more severe. Taking both parameters into account an MSAF risk factor (MRF) was defined. Based on a model of positive/negative predictive values, a cut-off point of MRF = 3 was selected, which prioritized sensitivity versus specificity. In ICP patients with MRF>3, the probability of MSAF was enhanced 4-fold. An increase in the frequency of MSAF was also associated with higher serum levels at diagnosis of alanine transaminase, alkaline phosphatase and direct bilirubin. Conclusions The risk of MSAF is associated not only with the magnitude of hypercholanemia at diagnosis but also with the early gestational onset of raised maternal serum bile acids.

Abstract
BACKGROUND Necrotizing enterocolitis (NEC) in neonates is devastating, and risk-factor identification is crucial. This study aimed to evaluate risk factors for NEC in different gestational age (GA) groups. METHODS Risk factors associated with NEC were investigated using a retrospective case-control design. Patients with Bell's Stage NEC≥II were divided into three groups based on GA: I, <34 weeks; II, ≥34 weeks but <37 weeks; III, ≥37 weeks. Each case was paired with two GA- and weight-matched controls. Data were collected from medical records, and univariate and conditional logistic regression analyses employed. RESULTS A total of 238 cases and 476 controls were enrolled. Variation in the months when NEC was diagnosed was noted, with a peak in January and a trough in August. Intrahepatic cholestasis of pregnancy and transfusion with packed red blood cells were significantly associated with NEC in preterm infants. Meconium aspiration syndrome was an independent risk factor for a greater chance of NEC development in full-term infants. Postnatal asphyxia and sepsis were associated with an increased risk of NEC in all groups. Probiotic use was associated with a reduced risk of NEC. Patients aged >34 weeks with congenital heart disease were more likely than controls to have NEC. CONCLUSION Intrahepatic cholestasis of pregnancy and meconium aspiration syndrome may be new risk factors for NEC.

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

Abstract
Intrahepatic cholestasis of pregnancy (ICP) is a complication of pregnancy resulting in elevation of serum bile acid levels. ICP is often associated with underlying liver disease, including hepatitis C. Bile acids in relationship to the acute infection of hepatitis C virus have not yet been delineated in the literature. A 26-year-old gravida 4 para 2103 with dichorionic, diamniotic twin gestation and history of intravenous drug abuse developed ICP in the setting of acute hepatitis C infection. In addition to clinical symptoms of pruritus and right upper quadrant pain, she developed severe elevation in bile acids, 239 micromol/L, and transaminitis aspartate aminotransferase 1033 U/L, and alanine aminotransferase 448 U/L. She received ursodeoxycholic acid and antenatal testing was performed. Patient delivered vaginally at 33-week gestation following preterm rupture of membranes. Neonates were admitted to NICU and had uncomplicated neonatal courses. In the setting of ICP with significant transaminitis and severe elevation of bile acids, consideration of acute viral hepatitis is important, especially considering the worsening opioid epidemic and concurrent increase in intravenous drug use in the United States. Further study is needed regarding the acute form of HCV infection and its effect on ICP and associated bile acids.
