guideline cholestasis of pregnancy

OBJECTIVES: The aims of this study were to verify the bile acids (BA) method and to establish reference intervals (RIs) for bile acids (BA) and biochemical and haematological parameters in Croatian pregnant women. METHODS: BA spectrophotometric method verification was performed on Siemens Atellica Solution CH 930 automated analyser using Sentinel reagent. Stability, precision, trueness, linearity, and RIs, as well as lipemia interference were tested according to CLSI guidelines...

Intrahepatic cholestasis during pregnancy is associated with a higher risk of prenatal and maternal complications. There are several new publications and guidelines on the detection and thresholds of intrahepatic cholestasis during pregnancy. However, the genetic background of this disease has rarely been investigated. This is a comprehensive review of the roles of genes in intrahepatic cholestasis during pregnancy.

OBJECTIVE: To identify strategies for reducing neonatal and maternal morbidity associated with intrahepatic cholestasis pregnancy (ICP). MATERIAL AND METHODS: The quality of evidence of the literature was assessed following the GRADE methodology with questions formulated in the PICO format (Patients, Intervention, Comparison, Outcome) and outcomes defined a priori and classified according to their importance. An extensive bibliographic search was performed on PubMed, Cochrane, EMBASE and Google Scholar databases...

PURPOSE: This study aimed to investigate the impacts of home quarantine on pregnancy outcomes of women with intrahepatic cholestasis of pregnancy (ICP) during the COVID-19 outbreak and whether the rational use of drugs will change these impacts. METHODS: This multi-center study was conducted to compare the pregnancy outcomes in women with ICP between the home quarantine group and the non-home quarantine group in southwest China. Propensity score matching was performed to confirm the pregnancy outcomes of the medication group and the non-medication group in women with ICP during the epidemic period...

Despite the progress in the quantification of xenobiotics, the development and validation of methods designed for endogenous substances still remain challenging due to the natural presence of the analytes in a biological matrix, leading to the inability to obtain a blank sample. Several generally recognized procedures are described to solve this issue, like using surrogate or analyte-depleted matrices or surrogate analytes. However, the workflows used do not always meet the requirements for developing a reliable analytical method or are cost-intensive...

BACKGROUND: Intrahepatic cholestasis of pregnancy (ICP) in the first trimester occurring after ovarian hyperstimulation syndrome (OHSS) is a rare condition and few cases are reported in the literature. Hyperestrogenism may explain this problem in genetically predisposed women. The objective of this article is to report one of these rare cases and offer an overview of the other published cases. CASE PRESENTATION: We report a case of severe OHSS followed by ICP in the first trimester...

This study reviewed the literature regarding the diagnosis, antepartum surveillance, and timing of delivery of pregnancies complicated by intrahepatic cholestasis of pregnancy, comparing the guidelines published by the Society for Maternal-Fetal Medicine in February 2021 and those published by the Royal College of Obstetricians and Gynaecologists in the United Kingdom in June 2022. Several key differences exist in the clinical guidelines between the 2 organizations. With regard to the diagnosis of intrahepatic cholestasis of pregnancy, the Society for Maternal-Fetal Medicine considers any elevation in bile acids above the upper limit of normal in the setting of maternal pruritus diagnostic of intrahepatic cholestasis of pregnancy, whereas the Royal College of Obstetricians and Gynaecologists requires a pregnancy-specific elevated bile acid level of ≥19 mmol/L for diagnosis...

PURPOSE: Intrahepatic cholestasis of pregnancy (ICP) is associated with adverse fetal and neonatal outcome. Evidence for improvement by obstetric management is sparse. Common international guidelines recommend induction of labor before term, however, they differ in recommendations of monitoring the disease and time point of active management. So far, an official guideline for treatment and management of ICP in Germany does not exist. This study aims to compile common practice and policy in obstetric management of ICP in German maternity units...

BACKGROUND: Intrahepatic cholestasis of pregnancy is associated with a significant risk of stillbirth, which contributes to variation in clinical management. Recent Society for Maternal-Fetal Medicine guidance recommends delivery at 36 weeks of gestation for patients with serum bile acid levels of >100 μmol/L, consideration for delivery between 36 and 39 weeks of gestation stratified by bile acid level, and against preterm delivery for those with clinical features of cholestasis without bile acid elevation...

BACKGROUND & AIMS: With the World Health Organization plan for hepatitis C elimination by the year 2030, and recent guideline recommendations to screen all women during pregnancy for HCV, data on HCV in pregnancy are needed to determine the association of HCV viremia with adverse pregnancy outcomes and mother-to-child transmission (MTCT). METHODS: This retrospective cohort study was performed in Ontario, Canada, using population-based administrative healthcare data...

AIM: To identify the incidence of Obstetric Cholestasis in a Maternity unit. To compare our investigation, criteria for diagnosis and management plan with National Guidelines. To assess adverse maternal and neonatal outcomes associated with this condition. METHOD: Serum Bile Acid requests are sent to an external laboratory, Biomnis in Dublin, for processing. A log of 2018 requests was obtained from Biochemistry. The pregnant patients with values > 8 mmol/L were selected...

OBJECTIVES: Bile acids serve as biomarkers for liver function and are indicators for cholestatic and hepatobiliary diseases like hepatitis, cirrhosis, and intrahepatic cholestasis of pregnancy (ICP). Sulfation and renal excretion of bile acids are important elimination steps. The power of ultra high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) allows specific profiling of primary and secondary bile acids as well as their sulfated counterparts. METHODS: Twenty-four sulfated and non-sulfated primary and secondary bile acids were quantified in urine with 15 corresponding stable isotope labeled internal standards by using two-dimensional UHPLC-MS/MS...

Introduction: Benign recurrent intrahepatic cholestasis is a rare hepatologic disorder characterized by recurrent, self-limited episodes of severe pruritus, jaundice, and elevated bile acids. While there are guidelines for the management of intrahepatic cholestasis of pregnancy, the literature regarding benign recurrent intrahepatic cholestasis and pregnancy is limited. Case: A 29-year-old G1P0 woman, with history of liver toxicity, had elevated total serum bile acid levels and liver enzymes documented at 8 weeks of gestation and throughout her pregnancy...

In the United States, it is estimated that 1% to 4% of pregnant women are infected with hepatitis C virus, which carries approximately a 5% risk of transmission from mother to infant. Hepatitis C virus can be transmitted to the infant in utero or during the peripartum period, and infection during pregnancy is associated with an increased risk of adverse fetal outcomes, including fetal growth restriction and low birthweight. The purpose of this document is to discuss the current evidence, provide updated recommendations regarding screening, review treatment, and address management of hepatitis C virus during pregnancy...

BACKGROUND: Reference intervals of clinical laboratory indexes are the basis of interpretation of test results. While intrahepatic cholestasis of pregnancy (ICP) could severely threaten maternal and fetal health, reference intervals of the biomarkers serum total bile acids (TBA) and glycocholic acid (GCA) are unsatisfactory. The purpose of this study was to derive gestational age-specific reference intervals for serum TBA and GCA in a Chinese population to promote early diagnosis of ICP...

AIMS: The aim of this study was to determine whether the metabolic glucose profile, based on glycaemic control and insulin requirements, was different in women with gestational diabetes mellitus (GDM) and intrahepatic cholestasis of pregnancy (ICP) compared to women with only GDM. METHODS: This retrospective cohort study comprised women with GDM and ICP matched with women with only GDM was undertaken at Aarhus University hospital, Denmark, from 2012 to 2019. A total of 46 cases and 184 controls were compared in relation to glycaemic control during pregnancy...
