BACKGROUND Intrahepatic cholestasis of pregnancy(ICP)is a pregnancy-specific liver condition that typically arises in the middle and late stages of pregnancy.Short-chain fatty acids(SCFAs),prominent metabolites of the gut microbiota,have significant connections with various pregnancy complications,and some SCFAs hold potential for treating such complications.However,the metabolic profile of SCFAs in patients with ICP remains unclear.AIM To investigate the metabolic profiles and differences in SCFAs present in the maternal and cord blood of patients with ICP and determine the clinical significance of these findings.METHODS Maternal serum and cord blood samples were collected from both patients with ICP(ICP group)and normal pregnant women(NP group).Targeted metabolomics was used to assess the SCFA levels in these samples.RESULTS Significant differences in maternal SCFAs were observed between the ICP and NP groups.Most SCFAs exhibited a consistent declining trend in cord blood samples from the ICP group,mirroring the pattern seen in maternal serum.Correlation analysis revealed a positive correlation between maternal serum SCFAs and cord blood SCFAs[r(Pearson)=0.88,P=7.93e-95].In both maternal serum and cord blood,acetic and caproic acids were identified as key metabolites contributing to the differences in SCFAs between the two groups(variable importance for the projection>1).Receiver operating characteristic analysis demonstrated that multiple SCFAs in maternal blood have excellent diagnostic capabilities for ICP,with caproic acid exhibiting the highest diagnostic efficacy(area under the curve=0.97).CONCLUSION Compared with the NP group,significant alterations were observed in the SCFAs of maternal serum and cord blood in the ICP group,although they displayed distinct patterns of change.Furthermore,the SCFA levels in maternal serum and cord blood were significantly positively correlated.Notably,certain maternal serum SCFAs,specifically caproic and acetic acids,demonstrated excellent diagnostic efficiency for ICP. 展开更多

BACKGROUND Intrahepatic cholestasis of pregnancy(ICP)is a rare but severe complication for both the mother and the unborn child.The diagnosis is primarily based on elevated serum levels of bile acids.In a large ICP cohort,we here study in detail liver stiffness(LS)using transient elastography(TE),now widely used to noninvasively screen for liver cirrhosis within minutes.AIM To specifically explore LS in a large cohort of women with ICP compared to a control group with uncomplicated pregnancy.METHODS LS and hepatic steatosis marker controlled attenuation parameter(CAP)were measured in 100 pregnant women with ICP using TE(Fibroscan,Echosens,Paris,France)between 2010 and 2020.In 17 cases,LS could be measured postpartum.450 women before and 38 women after delivery with uncomplicated pregnancy served as control group.Routine laboratory,levels of bile acids and apoptosis marker caspase-cleaved cytokeratin 18 fragment(M30)were also measured.RESULTS Women with ICP had significantly elevated transaminases but normal gammaglutamyl transferase(GGT).Mean LS was significantly increased at 7.3±3.0 kPa compared to the control group at 6.2±2.3 kPa(P<0.0001).Postpartum LS decreased significantly in both groups but was still higher in ICP(5.8±1.7 kPa vs 4.2±0.9 kPa,P<0.0001),respectively.In ICP,LS was highly significantly correlated with levels of bile acids and M30 but not transaminases.No correlation was seen with GGT that even increased significantly after delivery in the ICP group.Bile acids were mostly correlated with the liver apoptosis marker M30,LS and levels of alanine aminotransferase,aspartate aminotransferase,and bilirubin.In multivariate analysis,LS remained the sole parameter that was independently associated with elevated bile acids.CONCLUSION In conclusion,LS is significantly elevated in ICP which is most likely due to toxic bile acid accumulation and hepatocyte apoptosis.In association with conventional laboratory markers,LS provides additional non-invasive information to rapidly identify women at risk for ICP. 展开更多

Summary: This study aimed to identify biochemical predictors of adverse perinatal outcomes in in- trahepatic cholestasis of pregnancy (ICP). A total of 106 ICP cases were analyzed retrospectively by the combination of receiver operating characteristic curve and binary logistic regression analysis. "Adverse perinatal outcomes" included spontaneous preterm labor, meconium-staining of amniotic fluid, stillbirth and Apgar score ≤7 at 1 or 5 min. Total bile acid (TBA) [AUC=0.658, 95%CI (0.536, 0.781), P=0.031] was a valuable predictor for adverse perinatal outcomes. The critical value of TBA above which adverse perinatal outcomes were observed was 40.15 μmol/L (Youden's index=0.3). Binary multivariate logistic regression analysis revealed that the risk of adverse perinatal outcomes increased when TBA ≥40.15 /.tmol/L [OR=3.792, 95%CI (1.226, 11.727), P=0.021]. It is concluded that the risk of adverse perinatal outcomes in ICP increases when maternal TBA ≥40.15 gmol/L. 展开更多

The pathogenesis of intrahepatic cholestasis of pregnancy (ICP), a disorder that adversely affects maternal wellbeing and fetal outcome, is unclear. However, multiple factors probably interact along with a genetic predisposition. We would like to add some comments on a paper recently published concerning the role of ABCB11 and ABCC2 polymorphisms in both ICP and contraceptive-induced cholestasis, especially in the light of our recently published findings about a positive association between ICP and ABCC2 common variants. 展开更多

AIM: To investigate the association between total bile acid(TBA) level during intrahepatic cholestasis of pregnancy(ICP) and fetal lung surfactant alteration. METHODS: We recruited 42 ICP and 32 normal pregnancy women in this study. The maternal blood, fetal blood and amniotic fluid TBA level were detected using a circulating enzymatic method. Umbilical blood pulmonary surfactant protein A(SP-A) was evaluated with enzyme-linked immunosorbent assay. High performance liquid chromatography was used for the determination of phosphatidyl choline(PC), phosphatidyl inositol(PI), lysolecithin(LPC) and sphingomyelin(SM). Amniotic fluid lamellar body was counted with a fully automatic blood cell counter. Fetal lung area and fetal body weight were calculated from data obtained with an iu22 color supersonic diagnostic set. Clinical information of a nonstress test, amniotic fluid properties and neonatal Apgar score, and birth weight were recorded for review. RESULTS: The TBA level in maternal blood, fetal blood and amniotic fluid in the ICP group were significantly higher than that in the control group(maternal blood: 34.11 ± 6.75 mmol/L vs 4.55 ± 1.72 mmol/L, P < 0.05; fetal blood: 11.9 ± 2.23 mmol/L vs 3.52 ± 1.56 mmol/L, P < 0.05; amniotic fluid: 3.89 ± 1.99 mmol/L vs 1.43 ± 1.14 mmol/L, P < 0.05). Amniotic fluid PC and PI in the ICP group were significantly lower than that in the control group(PC: 65.71 ± 7.23 μg/m L vs 69.70 ± 6.68 μg/m L, P < 0.05; PI: 3.87 ± 0.65 μg/m L vs 4.28 ± 0.74 μg/m L, P < 0.05). PC/LPC ratio of the ICP group was lower than that of the control group(14.40 ± 3.14 vs 16.90 ± 2.52, P < 0.05). Amniotic LB in the ICP group was significantly lower than that of the control group((74.13 ± 4.37) × 109/L vs(103.0 ± 26.82) × 109/L, P < 0.05). Fetal umbilical blood SP-A level in the ICP group was significantly higher than that of the control group(30.26 ± 7.01 ng/m L vs 22.63 ± 7.42 ng/m L, P < 0.05). Fetal lung area/body weight ratio of the ICP group was significantly lower than that of the control group(5.76 ± 0.63 cm2/kg vs 6.89 ± 0.48 cm2/kg, P < 0.05). In the ICP group, umbilical cord blood TBA concentration was positively correlated to the maternal blood TBA concentration(r = 0.746, P < 0.05) and umbilical blood SP-A(r = 0.422, P < 0.05), but it was negatively correlated to the amniotic fluid lamellar corpuscle(r = 0.810, P < 0.05) and fetal lung area/body weight ratio(r = 0.769, P < 0.05). Furthermore, umbilical blood TBA showed a negative correlation to PC, SM and PI(r pc = 0.536, r sm = 0.438, r pi = 0.387 respectively, P < 0.05). The neonatal asphyxia, neonatal respiratory distress syndrome, fetal distress and perinatal death rates in the ICP group are higher than that of theCONCLUSION: ICP has higher TBA in maternal and fetal blood and amniotic fluid. The high concentration of TBA may affect fetal pulmonary surfactant production and fetal lung maturation. 展开更多

Intrahepatic cholestasis of pregnancy(ICP) is a peculiar disease in middle-late pregnancy with the pathological characteristics of hepatic capillary bile duct silts and is accompanied by clinical presentations of pruritus and bile acid(BA) elevation in serum. Maternal outcomes for patients diagnosed with ICP are usually good. However, fetal outcomes can be devastating with high frequencies of perinatal complications. Patients with ICP generally have an early delivery due to fetal complications. The current hypothesis is that ICP has higher frequencies of fetal complications due to high concentrations of BA which has toxic cellular effects to many organs. In lungs, it destroys the AT-II cells, decreasing phospholipids synthesis leading to the alveolar capillary permeability to increase and pulmonary surfactant to decrease. In heart, cholate can cross into the fetal compartment and causing fetal arrhythmias and decreased contractility. In the nervous system, high BAs can cause nerve cell denaturation and necrosis, mitochondria edema and membrane dissolve. In the placenta, high BA concentration can cause edema of the villous, decrease number of villous, intervillous thickening and balloon formation.In addition, high total BA can result in chorionic vein constriction and impaired fetal adrenal function. 展开更多

Maternal immune tolerance of the fetus is indispensable for a healthy pregnancy. Currently, the study of the immune microenvironment of the maternal-fetal interface has been a heated topic in reproductive immunology research. More and more studies show that the immune imbalance in the maternal-fetal interface plays a very important role in the incidence of intrahepatic cholestasis of pregnancy(ICP). However, the precise etiology and mechanism of immune imbalance in the occurrence of ICP is still unknown. In order to clarify the potential immunologic mechanisms of ICP, this review summarizes the recent studies of the decidual immunology microenvironment and the potential immunologic mechanisms related to the development of ICP. 展开更多

Objective: To evaluate the therapeutic effect of Yinchenghao decoction (YCHD, 茵陈蒿汤) and S-adenosy-L-methionine (SAM) in treating intra-hepatic cholestasis of pregnancy (TCP) and improving prognosis of perinatal newborn babies. Methods: Sixty in-patients of TCP were randomly divided into two groups, the group A treated with YCHD and the group B treated with SAM. The symptom of itching and serum biochemical indexes, including glycocholic acid, bilirubin and transaminase, were observed after 3 weeks treat-ment, and the prognosis of perinatal newborn babies between the two groups was compared after delivery. Results: After treatment, the symptom of itching, serum levels of glycocholic acid, bilirubin and transaminase improved significantly (P< 0.05) in both groups, and the prognosis of newborn in the two groups was similar (P>0. 05). Conclusion: Both YCHD and SAM could effectively treat ICP. The former is rather cheaper, so it is more feasible for spreading.Original article on CJITWM (Chin) 2004 ;24(4): 309 展开更多

BACKGROUND Intrahepatic cholestasis of pregnancy(ICP)is a liver disorder that occurs in pregnant women and can lead to a range of adverse pregnancy outcomes.The condition is typically marked by pruritus(itching)and elevated levels of liver enzymes and bile acids.The standard treatment for ICP has generally been ursodeoxycholic acid and ademetionine 1,4-butanedisulfonate,but the efficacy of this approach remains less than optimal.Recently,polyene phosphatidylcholine has emerged as a promising new therapeutic agent for ICP due to its potential hepatoprotective effects.AIM To evaluate the effect of polyene phosphatidylcholine/ursodeoxycholic acid/ademetionine 1,4-butanedisulfonate on bile acid levels,liver enzyme indices,and pregnancy outcomes in patients with ICP.METHODS From June 2020 to June 2021,600 patients with ICP who were diagnosed and treated at our hospital were recruited and assigned at a ratio of 1:1 via randomnumber table method to receive either ursodeoxycholic acid/ademetionine 1,4-butanedisulfonate(control group,n=300)or polyene phosphatidylcholine/ursodeoxycholic acid/ademetionine 1,4-butanedisulfonate(combined group,n=300).Outcome measures included bile acids levels,liver enzyme indices,and pregnancy outcomes.RESULTS Prior to treatment,no significant differences were observed between the two groups(P>0.05).Post-treatment,patients in both groups had significantly lower pruritus scores,but the triple-drug combination group had lower scores than the dual-drug combination group(P<0.05).The bile acid levels decreased significantly in both groups,but the decrease was more significant in the triple-drug group(P<0.05).The triple-drug group also exhibited a greater reduction in the levels of certain liver enzymes and a lower incidence of adverse pregnancy outcomes compared to the dual-drug group(P<0.05).CONCLUSION Polyene phosphatidylcholine/ursodeoxycholic acid/ademetionine 1,4-butanedisulfonate effectively relieves pruritus and reduces bile acid levels and liver enzyme indices in patients with ICP,providing a positive impact on pregnancy outcome and a high safety profile.Further clinical trials are required prior to clinical application. 展开更多

Intrahepatic cholestasis of pregnancy(ICP)is related to cholestatic disorder in pregnancy.Total urinary sulfated bile acids(SBAs)were found increased in ICP.We distinguished the metabolic profiling of urinary SBAs in ICP to find potential biomarkers for the diagnosis and grading of ICP.The targeted metabolomics based on high-performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS)was used to analyze urinary SBAs profiling in mild and severe ICP cases,as well as healthy controls.16 kinds of urinary SBAs were determined by HPLC-MS/MS.Sulfated dihydroxy glycine bile acid(di-GBA-S),glycine cholic acid 3-sulfate(GCA-3S),sulfated dihydroxy taurine bile acid(di-TBA-S)and taurine cholic acid 3-sulfate(TCA-3S)increased significantly in ICP group compared with the control group.Seven kinds of SBAs were significantly different(p<0.05)between the ICP group and the control group,with the variable importance in the projection(VIP)value more than one by the orthogonal partial least squares discriminant analysis(OPLS-DA).GCA-3S was well-suited to be used as the biomarker for the diagnosis of ICP with the sensitivity of 100%and specificity of 95.5%.A multi-variable logistic regression containing GCA-3S and di-GBA-S-1 was constructed to distinguish severe ICP from mild ICP,with the sensitivity of 94.4%and specificity of 100%.The developed HPLC-MS/MS method is suitable for the measurement of urinary SBAs profiling.Moreover,the urinary SBAs in the metabolomic profiling have the potential to be used as non-intrusive biomarkers for the diagnosis and grading of ICP. 展开更多

This study examined the effect of cholic acid (CA) on cultured cardiac myoeytes (CMs) from neonatal rats with an attempt to explore the possible mechanism of sudden fetal death in intra- hepatic cholestasis of pregnancy (ICP). Inverted microscopy was performed to detect the impact of CA on the beating rates of rat CMs. MTT method was used to study the effect of CA on the viability of CMs. CMs cultured in vitro were incubated with 10 ~maol/L Ca2+-sensitive fluorescence indicator fluo-3/AM. The fluorescence signals of free calcium induced by CA were measured under a laser scanning confocal microscope. The results showed that CA decreased the beating rates of the CMs in a dose-dependent manner. CA could suppress the activities of CMs in a time- and dose-dependent manner. CA increased the concentration of intracellular free calcium in a dose-dependent manner. Our study suggested that CA could inhibit the activity of CMs by causing calcium overload, thereby leading to the sudden fetal death in ICP. 展开更多

Background:Intrahepatic cholestasis of pregnancy(ICP)increases the risk of adverse pregnancy outcomes.This study aimed to explore the association between serum syndecan-1 and glypican-3 levels and the adverse perinatal outcome as well as the responses to the treatment of ursodeoxycholic acid(UDCA).Methods:This prospective,case control study included 88 pregnant women(44 women with ICP and 44 healthy controls).The primary end points were the perinatal outcome and the response to UDCA therapy.A logistic regression model was used to identify the independent risk factors of adverse pregnancy outcomes and reduced response to UDCA therapy.Results:Women with ICP had significantly higher serum syndecan-1(1.27±0.36 ng/m L vs.0.98±0.50 ng/m L;P=0.003),glypican-3(1.78±0.13 ng/m L vs.1.69±0.16 ng/m L;P=0.004),AST(128.59±1.44 vs.13.29±1.32 U/L;P<0.001),and ALT(129.84±1.53 vs.8.00±3.67 U/L;P<0.001)levels compared with the controls.The increased levels of syndecan-1(OR=4.715,95%CI:1.554–14.310;P=0.006),glypican-3(OR=8.465,95%CI:3.372–21.248;P=0.007),ALT(OR=1.382,95%CI:1.131–1.690;P=0.002),and postprandial bile acid(PBA)(OR=3.392,95%CI:1.003–12.869;P=0.026)were correlated to ICP.The adverse neonatal outcome was related to increased glypican-3(OR=4.275,95%CI:2.726–5.635;P=0.039),and PBA(OR=3.026,95%CI:1.069–13.569;P=0.037).Increases of syndecan-1(OR=7.464,95%CI:2.130–26.153,P=0.017)and glypican-3(OR=6.194,95%CI:2.951–13.002;P=0.025)were the risk factors of decreased response to UDCA treatment.Conclusion:Syndecan-1 and glypican-3 might be powerful determinants in predicting adverse perinatal outcome in patients with ICP,and they can be used to predict the response to the UDCA treatment. 展开更多

BACKGROUND Mutations that occur in the ABCB4 gene,which encodes multidrug-resistant protein 3,underlie the occurrence of progressive familial intrahepatic cholestasis type 3(PFIC3).Clinical signs of intrahepatic cholestasis due to gene mutations typically first appear during infancy or childhood.Reports of PFIC3 occurring in adults are rare.CASE SUMMARY This is a case study of a 32-year-old infertile female Chinese patient with a 15-year history of recurrent abnormal liver function.Her primary clinical signs were elevated levels of alkaline phosphatase andγ-glutamyl transpeptidase.Other possible reasons for liver dysfunction were eliminated in this patient,resulting in a diagnosis of PFIC3.The diagnosis was confirmed using gene detection and histological analyses.Assessments using genetic sequencing analysis indicated the presence of two novel heterozygous mutations in the ABCB4 gene,namely,a 2950C>T;p.A984V mutation(exon 24)and a 667A>G;p.I223V mutation(exon 7).After receiving ursodeoxycholic acid(UDCA)treatment,the patient's liver function indices improved,and she successfully became pregnant by in vitro fertilization.However,the patient developed intrahepatic cholestasis of pregnancy in the first trimester.Fortunately,treatment with UDCA was safe and effective.CONCLUSION These novel ABCB4 heterozygous mutations have a variety of clinical phenotypes.Continued follow-up is essential for a comprehensive understanding of PFIC3. 展开更多

AIM To study liver stiffness(LS) during pregnancy and its association with complications during pregnancy.METHODS In this observational, diagnostic study, 537 pregnant women were prospectively enrolled at the Department of Obstetrics and Gynecology, University hospital Heidelberg and Salem Medical Center. LS was measured using the Fibroscan device(Echosens, Paris) in all women and in 41 cases 24 h after delivery. Clinical and morphological data were recorded and abdominal ultrasound and standard laboratory tests were performed. No complications were observed in 475 women(controls) while preeclampsia and intrahepatic cholestasis of pregnancy(ICP) developed in 22 and 40 women, respectively.RESULTS In controls, LS increased significantly from initially 4.5 ± 1.2 kPa in the second trimester to 6.0 ± 2.3 kPa(P < 0.001) in the third trimester. In the third trimester, 41% of women had a LS higher than 6 kPa. Elevated LS in controls was significantly correlated with alkaline phosphatase, leukocytes, gestational age and an increase in body weight and body mass index(BMI). In women with pregnancy complications, LS was significantly higher as compared to controls(P < 0.0001). Moreover, in multivariate analysis, LS was an independent predictor for preeclampsia with an odds ratio of 2.05(1.27-3.31) and a cut-off value of 7.6 kPa. In contrast, ICP could not be predicted by LS. Finally, LS rapidly decreased in all women within 24 h after delivery from 7.2 ± 3.3 kPa down to 4.9 ± 2.2 kPa(P < 0.001).CONCLUSION During pregnancy, LS significantly and reversibly increases in the final trimester of pregnant women without complications. In women with preeclampsia, LS is significantly elevated and an independent noninvasive predictor. 展开更多
