A Retrospective Analysis of Fetal and Maternal Outcome in Patients with Intrahepatic Cholestasis of Pregnancy

Background: Introduction: Intrahepatic cholestasis of pregnancy (ICP), is the most common liver disease specific to pregnancy. Previous studies of fetal effects have suggested that ICP is associated with a higher rate of adverse neonatal outcomes including preterm birth, neonatal respiratory distress syndrome (RDS), meconium-stained amniotic fluid, neonatal intensive care unit admission, and stillbirth. Material & Methods: This was a 4 year retrospective observational study including 43,344 female who delivered in our hospital out of which 1126 cases of ICP were identified, who were compared with 1136 age and parity matched controls. Results: : Previous history and family history of ICP was significant in the ICP group. Gestational diabetes and preterm labour were more frequent in the ICP group. Mean birth weight was lower in the ICP group, rate of small for gestational age foetuses was not significantly different. Cesearean section and post-partum haemorrhage was more frequent in the ICP group. Adverse neonatal outcomes i.e. respiratory distress syndrome (RDS) and need for NICU admission were more in the ICP group. Conclusion: ICP is associated with increased rate of preterm delivery, post-partum hemorrhage and increased neonatal morbidity. Management of patients with ICP should be individualized based on the severity of symptoms and associated medical complications.

Efficacy of fetal left ventricular modified myocardial performance index in predicting adverse perinatal outcomes in intrahepatic cholestasis of pregnancy

SUMMARY 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.

Advances in the role of silence information regulator family in pathological pregnancy / 浙江大学学报·医学版

Aberrant maternal inflammation and oxidative stress are the two main mechanisms of pathological pregnancy. The silence information regulator (sirtuin) family is a highly conserved family of nicotinamide adenine dinucleotide (NAD)-dependent deacylases. By regulating the post-translational modification of proteins, sirtuin is involved in various biological processes including oxidative stress and inflammation. Nowadays, emerging evidence indicates that sirtuin may be closely related to the occurrence and development of pathological pregnancy. The down-regulation of sirtuin can cause spontaneous preterm delivery by promoting uterine contraction and rupture of fetal membranes, cause gestational diabetes mellitus through promoting oxidative stress and affecting the activity of key enzymes in glucose metabolism, cause preeclampsia by reducing the proliferation and invasion ability of trophoblasts, cause intrahepatic cholestasis of pregnancy by promoting the production of bile acids and T helper 1 cell (Th1) cytokines, and cause intrauterine growth restriction through inducing mitochondrial dysfunction. Moreover, the expression and activation of sirtuin can be modulated through dietary interventions, thus sirtuin is expected to become a new target for the prevention and treatment of pregnancy complications. This article reviews the role of the sirtuin family in the occurrence and development of pathological pregnancy and its influence on the development of the offspring.

Pregnancy outcome in patients with intrahepatic cholestasis of pregnancy: an observational case control study

Background: Intrahepatic cholestasis of pregnancy (IHCP) is the most common cholestatic liver disease, which may impact the foeto-maternal health. The present study is conducted to determine various factors including maternal and neonatal outcome in IHCP comparing with the controls.Methods: In this prospective case control study, pregnancy with IHCP is compared with asymptomatic non-IHCP controls. Classical pruritus, icterus, elevated liver enzymes were considered in diagnostic criteria of IHCP. Dermatological lesion, acute or chronic liver disease, and other causes of pruritus were excluded from study.Results: Out of 100 patients, 50 cases and 50 controls were included in this study. Incidence of IHCP was seen 3.914% of which 66% were primi presented maximum at 31-33 weeks. 86% of IHCP responded to medication. Mean value of ALT, AST and ALP was found significantly raised (p value-<0.001) in IHCP patients. 66% in IHCP and 64% in non-IHCP group had normal delivery and remaining 34% and 36 % had caesarean delivery respectively. There was no significant increase in foetal distress or low Apgar (<7 at 5 min) at birth or adverse neonatal or maternal outcome in IHCP group. However, there was a statistically high meconium stained liquor (MSL), neonatal jaundice, IUGR and NICU admission were noted in the IHCP group in comparison to non-IHCP group.Conclusions: There is a significant incidence of IHCP in the obstetrical population. The biochemical changes, meconium stained liquor, neonatal jaundice, IUGR and NICU admission were significantly high in IHCP in pregnancy.

Cholestasis of pregnancy: effects on maternal and fetal outcome

Background: Intrahepatic cholestasis of pregnancy (ICP) typically occurs in late pregnancy affecting 1.5-2% pregnancies. Limited data is available regarding its fetal and maternal implications. This study aims to assess the impact of ICP on maternal and fetal outcome.Methods: A total 200 patients with pruritus in later half of pregnancy were studied over a period of 18 months out of which 135 were diagnosed as ICP. Clinical and biochemical parameters like serum aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, total protein, and gamma glutamyl transferase was recorded. Maternal and fetal outcome was noted in the form of LSCS rate, preterm births, fetal distress and neonatal ICU admissions.Results: In this study, most common symptom was pruritus. Most of cases had onset of symptoms between 32-36 weeks. High LSCS rates were seen among cases. Intrapartum complications viz. meconium staining of amniotic fluid (57.8%), preterm delivery (11.9%), fetal distress (42.2%) were significantly higher in study population and there was high incidence of NICU admissions (49. 6% neonates) among cases mostly due to meconium aspiration and prematurity.Conclusions: ICP increases maternal morbidity and is associated with adverse perinatal outcome viz. increased risk of fetal distress, preterm births and sudden IUD at term as evidenced in this study. A timely intervention at 37-38 weeks will reduce the adverse outcomes.

Pregnancy outcome in women with intrahepatic cholestasis of pregnancy

Background: Intrahepatic cholestasis of pregnancy is a multifactorial condition of pregnancy diagnosed when otherwise unexplained pruritus with abnormal liver function test and neither of which has an alternative cause. The most appropriate gestational age for the delivery of women with ICP is yet to be determined. The present study is designed to determine whether with active intervention, pregnancy with ICP can be carried to a later gestation.Methods: Fifty Women with diagnosed a case of ICP were recruited into the study. The diagnosis of ICP was based on the symptoms, clinical examination and lab investigations. Group I: 25 women planned for delivery at POG 37 - 37+6 weeks of pregnancy. Group II: 25 women Planned for delivery at POG ≥38 weeks of pregnancy.Results: In group, one woman had preterm delivery at POG 36+2 weeks and rest of 24 women were delivered at POG 37-37+6 weeks. In group II, out of 25 women one woman had emergency LSCS at POG 35+3 weeks for MSL and induction of labour was done in 2nd for abnormal fetal well-being tests at POG 37 weeks. One woman had pre-term delivery at POG 36+1 weeks. Remaining 22 women in group II were delivered at POG ≥38 weeks. In the present study there was no significant difference in the gestational age at delivery between the two groups.Conclusions: It can be concluded that pregnancies with obstetric cholestasis can be carried to later gestation of ≥38 weeks under surveillance with UDCA treatment.

A study on feto-maternal outcome of intra hepatic cholestasis of pregnancy

Background: Intrahepatic cholestasis of pregnancy is one kind of the hepatic disorder which is unique to pregnancy. It is associated with many adverse pregnancy outcomes if doesn’t intervened at right time. It requires adequate clinico-biochemical correlation during management.Methods: A prospective observational study was conducted at multispecialty government zonal hospital. Total 137 IHCP patients were managed during the study period from 01 Jan 2017 to 30 Jun 2019. Incidence and pregnancy outcome in form of several maternal and fetal factors were analysed by appropriate statistical test using spps software version 20.0.Results: During the study period total 4872 patients were undergoing delivery and 137 patients were diagnosed with IHCP. The incidence of IHCP was 2.81%. Majority of cases 75 out 137 (54.74%) were nulligravida. Total 29.92% (41/137) cases were underwent LSCS delivery and of this 21.17% (29/137) were primary caesarean delivery. There were three still birth noted in IHCP study population. Total 28 cases (20.44%) of IHCP were presented with preterm labour. And NICU admissions of the study population were 32 new born babies (23.36%). 2.18% case of still birth was noted among study population.Conclusions: IHCP causes significant maternal and neonatal morbidity and is major contributor of preterm delivery, caesarean delivery, meconium stained liquor and NICU admission.

Perinatal outcomes and intrahepatic cholestasis of pregnancy: a prospective study

Background: Women with intrahepatic cholestasis of pregnancy (ICP) have an increased risk for postpartum haemorrhage, dyslipidaemia, preterm labour and operative interference. Fetus in ICP has been associated with an increased incidence of preterm labour, preterm prelabour rupture of membrane, fetal distress, abnormal CTG, meconium staining, spontaneous intrauterine death. The present study was done to evaluate the perinatal outcomes – maternal outcomes and fetal outcomes of ICP.Methods: This was a prospective observational study carried out in a tertiary care teaching hospital. Total 1100 pregnant women were screened during the study period. Patients with ICP were identified in maternity care units after eliciting history about itching. Pregnancies with pregnancy induced hypertension and other liver diseases in pregnancy were excluded.Results: 62 pregnant women with prevalence rate of 5.64% have been found to be suffering from ICP. The most frequently affected (22, 35.48%) age-group with ICP were belong to age > 35 years. A majority of pregnant women with intrahepatic cholestasis of pregnancy was of multipara. ICP was highly significantly associated with small for gestational age (SGA, p-value: 0.0003); abnormal cardiotocography (CTG, p-value: 0.0002); and meconium stained liquor (p-value: 0.0001). Caesarean section as mode of delivery found significantly associated (p-value: 0.0033) with ICP. Insomnia (p-value: 0.0045); dyslipidemia (p-value: 0.0011); and postpartum haemorrhage (p-value: 0.0122) were also found significantly with ICP.Conclusions: ICP can adversely affect fetal as well as maternal pregnancy outcomes. Maternal outcomes have good prognosis, but fetal outcomes can be improved by timely and effective intervention.

Intrahepatic cholestasis of pregnancy and hepatitis B virus infection during pregnancy elevates the risks of small for gestational age and low birth weight infants / 中华疾病控制杂志

Objective To explore the impact of hepatitis B virus infection, intrahepatic cholestasis during pregnancy on the risk of small for gestational age (SGA) and low birth weight (LBW), and analyze the interaction effect. Methods The study was conducted from Jan 2017 to Apr 2018 at the Gansu Provincial Maternity and Child Care Hospital in Lanzhou, China. The peripheral blood hepatitis B surface antigen (HBsAg) and total bile acids of pregnant women were determined by chemiluminescence method, unconditional Logistic regression models were used to estimate association between hepatitis B virus infection, intrahepatic cholestasis of pregnancy and the risk of neonate outcomes. Results After adjusting for confounding factors, compared to normal pregnant women, HBV infection alone or ICP alone during pregnancy did not increase the risk of SGA or LBW. The increased risk of born before term SGA (OR=1.76, 95% CI:1.16-2.65, P=0.007) and LBW infants (OR=1.85, 95%CI:1.44-2.38, P<0.001) were observed in pregnant women with HBV infection and ICP, the additive and multiplicative interaction were also observed for before term SGA ［RERI (95% CI) =6.54(0.14-12.94), AP (95% CI) =0.90%(0.68%-1.13%), S (95% CI)=7.03(1.38-42.64)］ and LBW ［RERI (95% CI) =5.69(0.48-10.90), AP (95% CI) =0.76%(0.55%-0.97%), S (95% CI)=8.02(1.92-33.43)］. Conclusions Our results suggest that pregnancy HBV infection combined with ICP increase the risk of SGA and LBW infants. These two risk factors had a synergistic effect.

MicroRNA-221/222 participates in the pathogenesis of intrahepatic cholestasis of pregnancy via promoting the apoptosis of human placental trophoblast HTR-8 cells / 中华肝脏病杂志

Objective@#MicroRNA-221/222 is involved in the pathogenesis of intrahepatic cholestasis of pregnancy (ICP) to promote the apoptosis of placental bile acids through human trophoblastic cells. This study investigates the effects of miR-221/222 on proliferation, apoptosis and apoptosis-related proteins of human trophoblast HTR-8/SVneo (HTR-8 cells) to understand its role in promoting trophoblastic apoptosis.@*Methods@#The experiment was divided into transfection group and negative control group. Transient transfection method was used in both groups. The transfection efficiency was detected by RT-QPCR after 48 h transfection. CCK-8 was used to detect the proliferation of HTR-8 cells and the apoptosis of HTR-8 cells were analyzed by flow cytometry. Western blot was used to detect the expression of B-cell Lymphoma 2 (Bcl-2) in HTR-8 cells. Data were compared with t-test.@*Results@#The expression of miR-221/222 transfected group (25.43±0.80, 22.70±0.95) was increased significantly in the HTR-8 cells than that to negative control group (1.14±0.14, 1.58±0.14), and P value was < 0.01, the difference was statistically significant. The expression of Bcl-2 protein in mir-221/222 transfection group was (0.56 ± 0.03, 0.53 ± 0.03), and the protein expression was decreased compared with negative control group (0.72 ± 0.003, 0.76 ± 0.04). P value was < 0.05, the difference was statistically significant, and compared with the mir-221/222 negative control group (8.827 ± 0.48, 11.80 ± 0.45), cell apoptosis of mir-221/222 transfection group (42.53 ± 4.47, 24.09 ± 2.53) increased significantly, P value was < 0.01, and the difference was statistically significant. Proliferation rate in mir-221/222 transfection group was (0.82 ± 0.02, 0.74±0.01), and proliferation was inhibited, when compared with control group (1.15 ± 0.08, 1.06 ± 0.08), P value was < 0.05, and the difference was statistically significant.@*Conclusion@#miR-221/222 may promote the apoptosis of human trophoblastic cells by down regulating the expression of apoptosis inhibitory protein bcl-2, leading to placental dysfunction and impairing the normal bile acid transport function of placenta. This mechanism may be involved in the occurrence and development of ICP.

Identification of Matrix Metalloproteinase-2 and 9 as Biomarker of Intrahepatic Cholestasis of Pregnancy

ABSTRACT Intrahepatic cholestasis of pregnancy (ICP) is a severe liver disease uniquely occurring during pregnancy. In this study we aimed to identify novel biomarker for the diagnosis of ICP in Chinese population. 50 healthy pregnant women, 50 mild ICP patients and 48 severe ICP patients were enrolled for this study. Liver function tests, including serum total bilirubin, direct bilirubin, alanine transaminase, aspartate aminotransferase and cholyglycine, were performed in all participants. After an overnight fast serum levels of total bile acids (TBA), matrix metalloproteinase (MMP)-2 and MMP-9 were measured, and their correlation with liver function tests were analyzed. The observed increase in serum TBA in ICP patients was not statistically significant which made it unreliable for diagnosis of ICP in Chinese population. On the other hand, both MMP-2 and MMP-9 serum levels exhibited a progressive and significant elevation in mild and severe ICP patients compared with healthy pregnant women, which also positively correlated with liver function tests. Serum levels of both MMP-2 and MMP-9 could be reliably used as laboratory abnormalities for accurate diagnosis and sensitive grading of ICP in Chinese population.

The results of Meta-analysis showed that, compared with control group, Yinzhihuang oral liquid significantly alleviated pruritus symptoms[MD=－0.68, 95%CI(－0.95,－041), P<0.000 01], reduced blood biochemical indexes including TBA[MD=－7.23, 95%CI (－10.88,－3.58), P=0.000 1], TB[MD=－1.90, 95%CI(－3.09,－0.70), P=0.002], ALT[MD=－39.08, 95%CI (－56.46,－21.70), P<0.000 1], and CG [MD=－0.71, 95%CI(－0.89,－0.52), P<0.000 01]. In the respect of pregnancy outcome, Yinzhihuang oral liquid can distinctly improve birth weight [MD=430.03, 95%CI (219.28, 640.78), P<0.000 1]. However, there was no significant difference in cesarean section rate [OR=0.93, 95%CI (0.36, 2.36), P=0.87], preterm birth rates [OR=0.63, 95%CI (0.28, 1.42), P=0.26], and neonatal asphyxia rate [OR=0.50, 95%CI (0.18, 1.43), P=0.20]. Yinzhihuang oral liquid showed better efficiency and slighter adverse reaction. However, more rigorously designed, double-blind, randomized controlled trials with large sample size and high quality are required to provide further evidences.

Mechanism of A549 cells apoptosis induced by umbilical artery serum in neonates delivered by women with intrahepatic cholestasis of pregnancy / 中华实用儿科临床杂志

Objective To explore the cause of bile acid-induced lung injury through investigating the cell apoptosis and the expressions of Capsase-3 in A549 cell of umbilical artery serum in neonates delivered by women with intrahepatic cholestasis of pregnancy.Methods A549 cell was used as target cell.The cultural cells in orifice were divided into control group and intrahepatic cholestasis of pregnancy-serum attacking group.The cells of control group were cultivated with normal nutritive medium.The umbilical arterial blood was cowered from the placental end of pregnant women with intrahepatic cholestasis after the baby had been delivered.Then the serum was gathered,and the cells of the intrahepatic cholestasis of pregnancy-serum attacking group were attacked by intrahepatic cholestasis of pregnancyserum.After 24 hours,lactate dehydrogenase leakage rate,expression of Caspase-3 and the apoptosis rate of the cells in the 2 groups were detected,respectively.Results The expression of Caspase-3 in A549 cells was observed in the light microscope,and Caspase-3 expre-ssion in the cytoplasm was brown.The lactate dehydrogenase leakage rate [(34.68 ±0.77) ％],the integrate optical density value (981.77 ± 55.21) of the expression of Caspase-3 and the rate of apoptosis [(27.86 ± 0.53) ％] of cells in intrahepatic cholestasis of pregnancy group were significantly higher than those of the cells in control group[(17.39±0.66)％,(540.63 ±38.41),(6.99 ±0.11)％] (t =-45.70,-15.96,-134.41,all P ＜ 0.05).Conclusions Umbilical artery serum in neonates delivered by women with intrahepatic cholestasis of pregnancy can induce apoptosis of A549 cells by up-regulating the expression of Caspase-3,and this was the potential machine of bile acid-induced lung injury in newborn infants.
