Abstract
INTRODUCTION Intrahepatic cholestasis of pregnancy (ICP) is a problem with an increasing incidence and negative maternal, fetal, and neonatal consequences. This problem is becoming increasingly important. This systematic review and meta-analysis aimed to determine the incidence of ICP and its adverse maternal, fetal, and neonatal adverse outcomes based on primary research studies. METHODS This systematic review and meta-analysis used Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guidelines and was conducted between June and September 2023 using the following keywords: obstetric cholestasis OR intrahepatic cholestasis AND pregnancy OR pregnant OR prenatal OR antenatal OR perinatal OR maternal OR fetal OR neonatal. Quality assessment of the studies was performed using the Critical Appraisal Checklists developed by the JBI Institute. Data were synthesized using meta-analysis methods. RESULTS The analysis included 10 studies published between 2013 and 2023. The meta-analysis showed that the incidence of ICP was 1.7% (odds ratio [OR], 0.021; 95% CI, 0.012-0.027), whereas maternal, fetal, and neonatal adverse outcomes included cesarean birth (OR, 2.938; 95% CI, 1.467-5.881), preterm birth or preterm prelabor rupture of membranes (OR, 4.241; 95% CI, 1.996-9.009), hypertensive disorders of pregnancy (OR, 3.715; 95% CI, 1.545-8.929), maternal infection (OR, 3.301; 95% CI, 2.917-3.737), neonatal intensive care unit admission (OR, 2.715; 95% CI, 1.458-5.056), birth weight less than or equal to 2500 g (OR, 2.518; 95% CI, 1.296-4.892), and small for gestational age (OR, 1.915; 95% CI, 1.424-2.573). DISCUSSION This systematic review and meta-analysis revealed that ICP has a high incidence and several maternal, fetal, and neonatal adverse outcomes. Therefore, midwives and other health professionals must be aware of these outcomes and provide appropriate care to pregnant individuals with ICP.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) is associated with an increased risk of cesarean section and adverse fetal outcomes. Currently, ICP diagnosis depends largely on serum levels of bile acids and lacks sensitivity and specificity for accurate diagnosis. Tongue diagnosis is an important diagnostic tool in traditional Chinese medicine (TCM) and is used in our clinic as complementary treatment and personalized medicine for ICP. However, the molecular basis of the manifestation of greasy white tongue coatings in ICP remains unknown. In this study, we performed untargeted metabolomic profiling of the serum, tongue coating, and saliva of 66 pregnant women, including 22 with ICP. The metabolomic profiles of the serum and tongue coatings showed marked differences between the two clinical groups. Forty-six differentially abundant metabolites were identified, and their relative concentrations correlated with total bile acid levels. These differential metabolites included bile acids, lipids, microbiota- and diet-related metabolites, and exposomes. Conventional biochemical markers, including serum aminotransferases and bilirubin, were not significantly increased in the ICP group, whereas the total cholesterol and triglyceride levels were significantly increased as early as the first trimester. Our data provide insights into the pathophysiology of ICP and implicate the gut-liver axis and environmental exposure. Tongue coating has the potential to be a non-invasive diagnostic approach. Further studies are required to validate the clinical utility of these findings.

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

Abstract
OBJECTIVE To evaluate the maternal and perinatal outcomes following antenatal screening for ICP using a retrospective approach. MATERIALS AND METHODS A retrospective study was conducted at the second affiliated hospital of Chongqing Medical University, Chongqing, China, from 2012 to 2017. Pregnant women registered for antenatal in our hospital were screened for ICP. The pregnant women with detailed delivery record and presenting with the diagnosis of ICP based on TBA level ≥10 mmol/L and abnormal liver enzymes were included in the study. METHOD The pregnant women with detailed delivery records presenting with the diagnosis of ICP based on TBA level ≥10 mmol/L and abnormal liver enzymes were included in the study. 1410 pregnant women were enrolled in this study. We selected 940 pregnant women without the diagnosis of ICP as our control and 470 pregnant women diagnosed with ICP as our case study. Data collection and sampling in the control group was done using microsoft excel (version 16.61) random number generator. RESULTS The mean age of the pregnant women and the gestational age at the time of diagnosis of ICP were 29.01 ± 4.3 years and 31.90 ± 8.83 weeks, respectively. It was found that a significant number of patients with ICP had a preterm birth and low birth weight (LBW), n = 151 (32.5%) P < 0.001 and n = 70 (14.9%) P < 0.001, respectively. A significant number of patients in the case group had a history of liver disease and gall bladder disease, p < 0.001 and p = 0.005, respectively, and a higher rate of GDM p < 0.001. Despite treatment, high TBA titer among ICP patients was associated with preterm delivery. CONCLUSION ICP in pregnancy leads to complications and poor perinatal outcomes. Fetal outcomes depend on the TBA levels; therefore, early diagnosis of ICP through routine screening followed by treatment is recommended in high-risk persons/areas.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) complicates among 0.2-2% of pregnancies and has been associated with adverse perinatal outcomes, including sudden stillbirth, meconium strained fluid, preterm birth, perinatal asphyxia, and transient tachypnea of the newborn. The diagnosis of "bile acids pneumonia" was previously proposed and a causative role of bile acids (BA) was supposed with a possible mechanism of action including surfactant dysfunction, inflammation, and chemical pneumonia. In the last few years, the role of lung ultrasound (LUS) in the diagnosis and management of neonatal respiratory distress syndrome has grown, and LUS scores have been introduced in the literature, as an effective predictor of the need for surfactant treatment among neonates with respiratory distress syndrome. We present four cases of infants born from pregnancies complicated by ICP, who developed respiratory distress syndrome early after birth. Lung ultrasound showed the same pattern for all infants, corresponding to a homogeneous alveolar-interstitial syndrome characterized by a diffuse coalescing B-line pattern (white lung). All infants evaluated require non-invasive respiratory support and in three cases surfactant administration, despite the near-term gestational age, with rapid improvement of respiratory disease and a good clinical outcome.

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

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

Abstract
PURPOSE Pruritus during pregnancy is associated with adverse maternal, pregnancy, and neonatal outcomes. We opted to assess the association between term pruritus and long-term neuropsychiatric hospitalizations of the offspring. METHODS In a population-based retrospective cohort study, the incidence of long-term neuropsychiatric hospitalizations was compared between offspring born to women with or without pruritus at term. Neuropsychiatric morbidity was assessed up to the age of 18 years according to ICD-9 codes associated with hospitalization of the offspring. A Kaplan-Meier survival curve was used to compare cumulative neuropsychiatric hospitalizations incidence and Cox proportional hazards models were used to control for confounders. The study included 226,918 deliveries of which 600 (0.26%) were in women with term pruritus. RESULTS Offspring born to women with pruritus exhibited a higher rate of long-term neuropsychiatric hospitalizations, specifically due to developmental and neurodegenerative disorders. Kaplan-Meier survival curve demonstrated a significantly higher cumulative incidence of long-term neuropsychiatric hospitalizations in offspring of women with pruritus. Using several Cox proportional hazards models, being born to a woman with pruritus was independently associated with an increased risk of long-term neuropsychiatric hospitalizations. CONCLUSIONS Maternal term pruritus was found to be independently associated with long-term neuropsychiatric hospitalizations of the offspring.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) was the most common liver disease specific to pregnancy. The symptoms of ICP were maternal pruritus and increased bile acid level in serum which was related to preterm birth, fetal distress, meconium-stained amniotic fluid and stillbirth. However, the mechanism of ICP progression on fetal development remained obscure. Sequencing data of 2 normal placenta samples and 4 intrahepatic cholestasis samples during pregnancy was analyzed by GEO2R. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) were used for analysis of differentially expressed genes. MCODE - A plug-in of Cytoscape was used for molecular complex detection. STRING, Cytoscape, GeneMANIA, NetworkAnalyst, TransmiR, JASPAR, DGIdb and DrugBank were used in this study. Furthermore, histopathological and cell experiments were used to verify our results. Our study identified the key KEGG pathway and four MCODEs which were closely with ICP development, further, sorted by degree centrality, we showed top 30 genes from 7209 differential genes, such as TP53, SRC, EGFR, ESR1, IL10, CD8A, MAPK3, PTPRC, EGF, KIT, ITGAM, LEP and CSF2, etc. Moreover, these hub genes participated in JAK-STAT3 signaling pathway and STAT1/3 regulated these genes expression in a direct way or miRNA-mediated manner. Drug-target analysis about up-regulated genes among hub genes showed that these genes contained multiple drug action site. Furthermore, hub gene-EGFR was associated with destroyed autophagy and ferroptosis. In conclusion, our study analyzed key genes and pathways in ICP development. JAK-STAT3 pathway and EGFR might be a potential target for ICP therapy.
