Early detection of drug-induced cholestasis remains a challenge during drug development. We have developed and validated a biorelevant sandwich-cultured hepatocytes- (SCH) based model that can identify compounds causing cholestasis by altering bile acid disposition. Human and rat SCH were exposed (24-48h) to known cholestatic and/or hepatotoxic compounds, in the presence or in the absence of a ...

Background: Outcome of infantile intrahepatic cholestasis is highly variable. Aim to investigate various factors affecting outcome of infantile cholestasis. Methods: Retrospective study was conducted through data collection of 70 infant’s files who presented with intrahepatic cholestasis. They were divided into two groups according to the fate of jaundice at the end of the first year follow up....

INTRODUCTION Parenteral nutrition-associated cholestasis is well recognized phenomenon in the term and preterm infant receiving long-term parenteral nutrition. OBJECTIVES The aim of this study was to evaluate the effect of ursodeoxycholic acid (UDCA) use on cholestasis in newborns on prolonged TPN. METHODS A total of 56 infants were enrolled in this retrospective study: control group consis...

Progressive familial intrahepatic cholestasis is a serious disease of the liver, known as Byler disease, characterized by hepatocellular cholestasis. Severe pruritus and high serum bile acid concentrations are the most important diagnostic criteria of this autosomal recessive inherited disease. Here, we present a five-year-old boy with lichenification and enlargement of hands and feet as a sign...

Intrahepatic cholestasis is a rare but potentially fatal complication of sickle cell disease [1]. Sickle cell intrahepatic cholestasis (SCIC) is characterised by right upper quadrant pain, hepatomegaly and progressive hyperbilirubinaemia. To date 15 adult patients have been reported in the literature and only six survived [2]. We present a case of haemoglobin S/Beta thalassaemia with intrahepat...

OBJECTIVE To evaluate postpartum blood loss in women with treated intrahepatic cholestasis of pregnancy. METHODS In a retrospective case-control study, 15,083 deliveries including 348 women with intrahepatic cholestasis of pregnancy (2.3%) were analyzed from 2004 to 2014. To adjust for differences in baseline characteristics, a propensity analysis was performed and women in the control group ...

The discovery of unidirectional, ATP-dependent canalicular transport systems (also termed "export pumps") for bile salts, amphiphilic anionic conjugates, lipophilic cations, and phospholipids has opened new opportunities for understanding biliary physiology and the pathophysiology of cholestasis. In addition, ATP-independent canalicular transport systems for glutathione and bicarbonate contribu...

The feasibility and reproducibility of liver stiffness measurements using Supersonic Shear-wave Imaging (SSI) in preterm neonate have not been reported. Our aim was to determine if liver stiffness differs between intra-uterine growth restriction (IUGR) and appropriate for gestational age (AGA) preterm infants with/without cholestasis. We measured liver stiffness (in kPa) in 45 AGA and 18 IUGR p...

Intrahepatic cholestasis is a kind of clinical syndrome along with hepatotoxicity which caused by intrahepatic and systemic accumulations of bile acid. There are several crucial generating factors of the pathogenesis of cholestasis, such as inflammation, dysregulation of bile acid transporters and oxidative stress. SIRT1 is regarded as a class III histone deacetylase (HDAC). According to a set ...

Hepatobiliary transport systems mediate hepatic uptake and biliary excretion of bile acids, bilirubin and other biliary constituents. Hereditary or acquired defects of these transporters may cause or maintain cholestasis and jaundice under various clinical conditions including progressive familial intrahepatic cholestasis (PFIC) 1-3 or its milder forms, benign recurrent intrahepatic cholestasis...
