Liver Function and Bilirubin Flashcards | Quizlet

Jaundice is a common clinical finding in the neonate. During the first week after birth, visible jaundice may appear in as many as one third of them.1 For most, clinical jaundice and transient elevation of serum bilirubin concentration are part of the physiologic maturation of bilirubin metabolism and excretion. In some neonates, however, severe or persistent hyperbilirubinemia results from underlying disorders of bilirubin production, conjugation, or excretion.

The synthesis of bilirubin glucuronide in animal and human liver

High levels are seen inhemochromitosis, liver damage, pernicious anemia and hemolytic anemia.

This disorder is clinicallyand biochemically similar to benign intrahepatic cholestasis. Itoccurs in the third trimester of pregnancy when the estrogen level is the highestand disappears postpartum. The affected subjects appear to belong to familieswith benign intrahepatic cholestasis trait. Gonadal steroid appear to ply a determiningrole in the cause of this syndrome. Histology of the liver showscentrolobular cholestasis similar to benign intrahepatic cholestasis. It is mostfrequent in Scandinavia (1/100), Bolivia and Chile (1/10).The disorder is safefor the mother but not for the fetus who will suffer premature births andstillbirths due to placental infarcts. The mothers have higher incidence ofgallstones. Sometimes the disorder manifests itself only with presence ofpruritus without jaundice. (Pruritus gravidarum). The patients are notseverely ill as in fatty liver of pregnancy, hepatitis, obstructive jaundice.

Porphyrin and Heme Synthesis and Bilirubin Metabolism

Many drugs producecholestasis. The first cases reported were due to chlopromazine and syntheticsteroids now out of market (Nilavar). Synthetic oral contraceptives are high inthe list. They appeared to act on sensitivity base and affect only sensitiveindividuals. Many appear to impair the secretory function of the hepatocytes. Andthe list is increasing with the advent of new drugs. The liver in these casesmay show

It is due to avery transient insufficiency of glucuronyl transferase. During the first fewdays of life there is an overproduction of bilirubin and an underdevelopedmechanism of the liver to dispose of bilirubin.

Is due to a severedeficiency of glucuronyl tranferase. Deep jaundice develops tat birth, Highserom unconjugated hyprbilirubinemia, >20 mg/dl., not responding tophenobarbital. Absent formation of diglucuronides. Death usually in the firstyear or two with kernicterus. Phototherapy, plasmaferesis and albumin exchangeare beneficial. Liver transplantation may be life-saving. The liver ishistologically normal. A similar condition exists in Gann rat. Fortunately this syndromeis rare. Only 100 or more cases have been described. It is apparently ahereditary autosomal recessive trait.

Jaundice is one of the common types of liver diseases that refers to the golden yellow appearance of skin and sclera. It results from too much accumulation of bilirubin in the body fluids. Jaundice is first noticeable in the sclera of the eyes. You call this yellow discoloration of the sclera as icterus. Jaundice is evident in skin when serum bilirubin level is 2.5 to 3 mg/dL.

Certainly, the degree of liver disease and the complexity of the operation are important factors. For surgery not involving the liver, there is a >40% mortality risk in a Child’s C cirrhotic. For liver resection, the mortality risk is so high in Child’s C patients that the surgery should not be performed. (In fact, the only operation a Child’s C cirrhotic should receive is a liver transplant!).

BILIRUBIN METABOLISM - PowerPoint PPT Presentation

The hike in bilirubin level is actually due to the rapid breakdown of red blood cells. This occurs due to some disease and infection that also affects liver. So, the treatment of jaundice completely depends on the cure of underlying cause. In other words, you have to identify and treat the condition that is responsible for the higher level of bilirubin in the body.
