NCT04718961
Part 1 is an open-label randomized study of volixibat in patients with Intrahepatic Cholestasis of Pregnancy (ICP) and elevated serum bile acid concentrations (sBA) to evaluate safety and tolerability of two doses of volixibat. Part 2 is a double-blind, placebo controlled, study designed to evaluate the safety and efficacy of a selected volixibat dose.
NCT06364969
This study hopes investigate the itch-inducing ability of different potential pruritogen candidates of cholestasis pruritus, especially the intrahepatic cholestasis of pregnancy (ICP). In this study, a combination of skin application and needle-free subcutaneous injection was used to investigate whether human endogenous molecules can cause itching. And a questionnaire is used to quantify the intensity of different candidates-induced itch.
NCT05637151
Objective:The aim of this study was to investigate the relationship between delayed cord clamping and neonatal bilirubin levels in pregnant women with intrahepatic cholestasis of pregnancy. Method:This observational prospective cohort study included a total of 200 pregnant women at 37-40 gestational weeks. Among them, 100 pregnant women with intrahepatic cholestasis of pregnancy were divided into 50 cases of immediate cord clamping group （ICC in pregnant women with ICP）and 50 cases of delayed cord clamping group（DCC in pregnant women with ICP）, and 100 normal pregnant women were also divided into 50 cases of immediate cord clamping group （ICC in normal pregnant women）and 50 cases of delayed cord clamping group（DCC in normal pregnant women）. The bilirubin levels of neonates in each group were compared.
NCT05151913
This is an exploratory non-therapeutic study to study the microbiome patterns during pregnancy in women with ICP in order to identify specific bacterial strains for further product development.
NCT03519399
Intrahepatic cholestasis of pregnancy (ICP) is a liver disorder of pregnancy that typically presents in late pregnancy with generalised itching. ICP is associated with an increased risk of pregnancy complications, including premature labour, fetal distress, and stillbirth. Models of the fetal heart (using cells from rodents) have shown that high bile acids levels cause an abnormal heart rhythm (arrhythmia), which may be the cause of stillbirth. High levels of bile acids also cause preterm labour in animal models. This pilot study aims to assess whether severe ICP, defined as maternal serum bile acid levels ≥40μmol/L, is associated with abnormal fetal heart rhythms and abnormal myometrial contractility, which may lead to preterm birth. Fetal heart rhythms and myometrial contractility will be recorded using a portable electrocardiogram (ECG) device, the Monica AN24. This monitors the fetal heart and myometrial activity via stickers applied to the mother's abdomen. It also records the maternal ECG. It will also study women with uncomplicated pregnancy, in order to make comparisons. The importance of maternal position during sleep has also more recently been established, with some studies demonstrating an association between the risk of stillbirth and the position the mother was sleeping in. Work by Stone et al published this year has shown that the maternal sleep position has a significant impact on the fetal sleep state and fetal heart rate, (in particular something called the fetal RMSSD value). The researchers therefore wish to identify any potential correlation between fetal heart arrhythmia and maternal sleep position. To do this they will use a Zephyr BioPatchTM which provides a clear indication of whether the patient was in left lateral, right lateral or supine position.
NCT01906827
The bile acids has been demonstrated to cause arrhythmia and abnormal calcium dynamics in cultured neonatal rat cardiomyocytes. Bile acids may alter maternal cardiomyocyte function like fetus.Increased P-wave duration and P-wave dispersion have been reported in various clinical settings. The investigators hypothesized that PWD and p wave duration may affect in pregnancy with ICP.
NCT01898832
The aim of this study is to investigate maternal and fetal serum IL-17 levels in pregnant women with intrahepatic cholestasis of pregnancy and to find out if Th-17 cells have a role in progress of intrahepatic cholestasis of pregnancy.
