Cholestasis can occur in newborns due to infections. However, the manifestations of the underlying infections usually dominate the presentation. We present a 2-month-old infant who presented with jaundice and no fever or signs of systemic illness. Liver biopsy was suggestive of cholangitis. He was subsequently detected to have urinary tract infection with Klebsiella pneumoniae. The child was tr...

Aim of the study Assessment of the expression of cluster of differentiation (CD)3, CD4, and CD8 T cells in biliary atresia (BA) cases in comparison to neonatal cholestasis other than BA. Material and methods This study included 79 patients: 34 patients with BA (BA group) and 35 patients with neonatal cholestasis due to causes other than BA (cholestasis group), and 10 normal liver donor as a c...

Neonatal cholestasis results from a variety of etiologies, including anatomic, infectious, and metabolic abnormalities. Hyperthyroidism, in contrast to hypothyroidism, is infrequently associated with neonatal cholestasis. Newborn screening is an important tool to detect newborn metabolic disorders, including thyroid dysfunction. However, one must exercise caution when interpreting these reports...

Neonatal cholestasis is a prolonged elevation of the serum levels of conjugated bilirubin beyond the first 14 days of life. Commonest etiologies include extrahepatic conditions like biliary atresia, intrahepatic like congenital malformations, infections and inborn errors of metabolism. TORCH infections constitute 22% cases of neonatal hepatitis, of which Cytomegalovirus is the commonest agent. ...

AIM The aim of this study is to find-out the possible etiologies in Iranian infants less than three months in Shiraz, South of Iran. BACKGROUND Cholestatic jaundice most probably occurs due to a pathological condition and the most frequent causes in early infancy are neonatal hepatitis and biliary atresia. Early diagnosis and treatment of infantile cholestasis can improve prognosis of liver d...

Cholestasis is frequent in neonates (1/2,500 live births) and in young children. It includes many etiologies with sometimes poor prognosis. In case of neonatal cholestasis, the most important point is to look at the stool color and to rule out biliary atresia which needs to be surgically treated before the 45th day of life. Biliary atresia represents almost 50% of cases of neonatal cholestasis,...
