Inhibition of the bile salt export pump (BSEP) has been recognized as a key factor in the development of drug-induced cholestasis (DIC). The risk of DIC in humans has been previously assessed using in vitro BSEP inhibition data (IC50) and unbound systemic drug exposure under assumption of the "free drug hypothesis." This concept, however, is unlikely valid, as unbound intrahepatic drug concentr...

Thus, the changes in maternal steroid metabolism caused by cholestasis are reflected in the steroid profile of the fetoplacental circulation. Furthermore, maternal intrahepatic cholestasis may result in the production of some substance which crosses the placenta and affects fetal steroid metabolism. Received for publication 7 November 1973 and in revised form 13 February 1974. INTRODUCTION Intr...

BACKGROUND Neonatal cholestasis syndrome with an intra or extrahepatic origin has been associated to viral infections. The participation of the cytomegalovirus in the etiopathogenesis of neonatal hepatitis has been already known for some time, but only recently there have been indications that this virus may be one of the possible etiological factors for extrahepatic biliary atresia. AIMS To ...

To assess the extent of microfilaments in cholestatic liver diseases we examined the cytoplasmic microfilaments in intrahepatic and extrahepatic cholestasis in man by electron microscopy. Study subjects were two patients with drug-induced intrahepatic cholestasis, three patients with intrahepatic cholestasis due to viral hepatitis, four patients with extrahepatic cholestasis due to stones of th...

Intrahepatic cholestasis is a main cause of hepatic accumulation of bile acids leading to liver injury, fibrosis, and liver failure. Our previous studies proved that Calculus Bovis Sativus (CBS) can restore biliary transport function through upregulating the multidrug resistance-associated protein 2 (MRP2) and breast cancer resistance protein (BCRP) in 17α-ethynylestradiol- (EE-) induced intrah...

BACKGROUND AND AIMS Large indels are commonly identified in patients but are not detectable by routine Sanger sequencing and panel sequencing. We specially designed a multi-gene panel that could simultaneously test known large indels in addition to ordinary variants, and reported the diagnostic yield in patients with intrahepatic cholestasis. METHODS The panel contains 61 genes associated wit...

Post-liver transplant intrahepatic cholestasis is consequent to the impairment of bile flow or formation. It may develop in the early (within 6 months) or in the late (more than 6 months) post-liver transplant period and different causes may be recognized according to the time elapsed from a liver transplant. The raise at various degrees of serum bilirubin, alkaline phosphatase, and gamma-gluta...

Intrahepatic cholestasis of pregnancy (ICP) represents a rare but severe pathology with serious consequences on the outcome of pregnancy. We present the cases of two sisters that came to our clinic with ICP in successive pregnancies. The fetus from a pregnancy with cholestasis can be affected by preterm birth, respiratory distress syndrome, intrauterine death in the third trimester and a possib...

OBs-mucTivF jaundice is amenable to surgical treatment when the obstruction is extrahepatic. In recent years it has been recognised that the obstruction may be intrahepatic and the complete picture of obstructive jaundice may be seen without obstruction of the main bile ducts. It is important to differentiate between intrahepatic anid extrahepatic cholestasis in order to avoid unnecessary surgi...

conclusions udca decreased the pruritus score, tba, and alt levels more effectively than same, reducing the rate of preterm delivery for icp. evidence acquisition a meta-analysis of all randomized controlled trials (rcts) comparing udca, same, and combination therapy was performed. we carried out a literature search using pubmed, embase, the cochrane register of controlled trials, and the scien...
