Introduction: Neonatal cholestasis due to endocrine diseases is infrequent and poorly reco­ gnized. Referral to the pediatric endocrinologist is delayed. Objective: We characterized cholestasis in infants with congenital pituitary hormone deficiencies (CPHD), and its resolu­ tion after hormone replacement therapy (HRT). Subjects and methods: Sixteen patients (12 males) were included; eleven wit...

AIM Cholestasis triggers fibrogenesis in the liver. Hepatic cyclooxygenase-2 (COX-2) expression increases in various chronic liver diseases caused either by viruses or toxins. We hypothesized that selective COX-2 inhibitor meloxicam could suppress inflammation and fibrogenesis in a rat model of cholestasis induced by bile duct ligation (BDL). METHODS Forty-three Sprague-Dawley rats were assig...

In order to cast light on the anti-cholestatic and cytoprotective properties of ursodeoxycholic acid (UDCA), intrahepatic transport and secretion of bile salts and biliary phospholipids were investigated by using isolated perfused livers from colchicine-pretreated rats. Administration of taurocholic acid (TCA) after colchicine pretreatment induced marked cholestasis. Tauroursodeoxycholic acid (...

Cholestasis results from impairment in the excretion of bile, which may be due to mechanical obstruction of bile flow or impairment of excretion of bile components into the bile canaliculus. When present, cholestasis warrants prompt diagnosis and treatment. The differential diagnosis of cholestasis beyond the neonatal period is broad and includes congenital and acquired etiologies. It is impera...

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 ...

Intrahepatic cholestasis of pregnancy (ICP) is an idiopathic liver disease while the biochemical characteristic is the elevated level of total bile acid (TBA). The present study investigated whether miR-148a mediates the induced effect of estrogen on the development of ICP and the proper mechanism: PXR/MRP3 signal pathway. mRNA expression was detected by qPCR, protein expression was detected by...

Intrahepatic cholestasis in the form of paraneoplastic phenomena is an uncommon presentation of Hodgkin's lymphoma (HL). Herein we report the diagnosis of mixed type HL-related idiopathic intrahepatic cholestasis in a 73-year-old man presenting with jaundice, after the inguinal lymph node biopsy indicative of mixed cellular type HL and liver biopsy consistent with intrahepatic cholestasis, foll...

OBJECTIVE Cystatin C is a very potent inhibitor of cysteine proteinases and, it has been clinically applied as a sensitive marker in monitoring of renal and liver functions. The aim of this study was to reveal whether cystatin C may be a useful marker for distinguishing intra- versus extrahepatic cholestasis. MATERIALS AND METHODS Serum cystatin C concentrations were determined by nephelometr...

Severe intrahepatic cholestasis occurred in a patient after taking nitrofurantoin, ampicillin, and cloxacillin. As only nitrofurantoin was known to cause cholestasis she was given cloxacillin again two years later. The cholestasis reappeared at once. A macrophage inhibition factor test confirmed that cloxacillin was the offending drug. Cloxacillin should be added to the growing list of drugs ca...

BACKGROUND/AIMS To examine the extent and mechanisms of apoptosis in cholestatic liver injury and to explore the role of the transcription factor nuclear factor-kappa B in protection against bile acid-induced apoptosis. METHODS Cholestatic liver injury was induced by bile duct ligation in Wistar rats. Furthermore, primary cultures of rat hepatocytes were exposed to glycochenodeoxycholic acid ...
