Introduction: Early differentiation of biliary atresia from neonatal hepatitis is of utmost importance, since on time surgery of biliary atresia significantly improves the outcome. Hepatobiliary scintigraphy is an integral part of diagnosis work-up of these patients; however its specificity for diagnosis of biliary atresia is suboptimal. In this study we evaluated the value of ursodeoxycholic a...

Recognition of neonatal liver disease has been heavily dependent on the occurrence of jaundice. In most instances the jaundice is related to specific disturbances in bilirubin transport and other tests of liver function are normal. In contrast, hepatitis and other liver diseases not specifically affecting bilirubin transport often go undetected unless jaundice occurs. The development of practic...

-Glutamyltransferase (GGT) is a microsomal enzyme that is widely distributed in human tissues involved in secretory and absorptive processes, particularly the bile canaliculi. Serum GGT is elevated in liver diseases affecting the biliary system, such as extrahepatic biliary atresia, sclerosing cholangitis and progressive familial intrahepatic cholestasis (PFIC) type 3. Conversely, two other sub...

background: neonatal cholestasis is an important infant’s diseases of liver and biliary, they are wide range of situation including; idiopathic neonatal hepatitis, extrahepatic biliary tract atresia, choledochal cysts and infectious diseases. lack of early diagnosis of the disease can be followed by irreparably complications. the aim of this study was determination the histopathological causes ...

Infants with idiopathic perinatal fibroinflammatory obliteration of the lumen of the extrahepatic biliary tree ("biliary atresia") invariably died of biliary cirrhosis before surgical techniques were devised to permit drainage of bile into the duodenum. Survival rates in operated patients now approach 75 percent at 10 years. While definitive diagnosis of biliary atresia without the use of chola...

BACKGROUND Livers of infants with biliary atresia and of neonatal mice infected with rotavirus (RRV) have increased expression of interferon-gamma (IFNgamma) and interleukin (IL)-12. While the expression of IFNgamma regulates the obstruction of extrahepatic bile ducts by lymphocytes, the role of IL-12 in the pathogenesis of biliary obstruction is unknown. Based on the role of IL-12 as a key pro...

The etiology and pathogenesis of bile duct obstruction in children with biliary atresia are largely unknown. We have previously reported that, despite phenotypic heterogeneity, genomic signatures of livers from patients display a proinflammatory phenotype. Here, we address the hypothesis that production of IFN-gamma is a key pathogenic mechanism of disease using a mouse model of rotavirus-induc...

Extrahepatic biliary atresia (EHBA) is an inflammatory fibrosing process affecting the extrahepatic and intrahepatic biliary tree resulting in fibrous obliteration of the extrahepatic biliary tract, ductopenia of intrahepatic bile ducts, and biliary cirrhosis. EHBA is divided in a fetal, prenatal or embryonic, and a more common, perinatal form. The symptoms of the fetal form start shortly after...

The diagnostic accuracy of laboratory investigations in the prelaparotomy differentiation between extrahepatic biliary atresia (EHBA) and intrahepatic disease (IHD) was assessed in 86 consecutive infants presenting with conjugated hyperbilirubinaemia. Forty five infants had EHBA and 41 IHD. The mean serum bilirubin concentration, gamma-glutamyltranspeptidase (GGT) activity, and the GGT/aspartat...

Background: Aflatoxin B 1 induced hepatitis was reported to be associated with characteristic features of centrizonal scarring, hepatic venous occlusion, ductular proliferation and cholestasis, focal syncytial giant cell giant cell transformation of hepatocytes, and pericelluar fibrosis which is congruent to biopsy findings in extra hepatic biliary atresia (EHBA). Aim of Work: Is to study aflat...
