Jaundice hemolytic

In jaundice secondary to hemolysis, the increased production of bilirubin leads to increased production of urobilinogen, which appears in the urine in large amounts. Bilirubin is not usually found in the urine in hemolytic jaundice (because unconjugated bihmbin does not pass into the urine), so that the combination of increased urobilinogen and absence of bihmbin is suggestive of hemolytic jaundice. Increased blood destruction from any cause brings about an increase in urine urobilinogen. 

Another common liver disease, alcoholic liver damage produced by moderate to heavy alcoholic intake, is also reflected by an elevation of the serum GOT and GPT activities. The serim glutamyl transferase activity is reported to be a sensitive index of alcoholic intake and can serve to monitor persons on alcoholic withdrawal programs (60). The LD-5 isoenzyme arises mainly from liver tissue, but has a short half-life (61), which is about 1/5 and 1/2 of the half life of the transaminases, GPT and GOT respectively. Some authors consider that a normal LD-5 isoenzyme activity in a jaundiced patient is sufficient evidence to exclude primary liver disease and that obstruction is probably responsible for the jaundice (62). In hemolytic jaundice the LDH-1 and 2 isoenzymes are elevated.

Answer C. Only option C is characteristic of hemolytic jaundice indirect hyperbilirubinemia with no spillover of the water-insoluble unconjugated form into the urine. 

The serum IgM concentration in one of the patients in Nigeria, who was only 19 years of age, was above 4000 mg/100 ml. On Immunoelectrophoresis, there was spontaneous precipitation of massive quantities of cryomacroglobulins which could not be removed from the agar gel even after extensive washing of the gels for several days. Clinically this patient was jaundiced and anemic, probably due to hemolysis of his red cells by the massive increase of the serum IgM. The monoclonal protein in both the serum and urine were of the IgM k type. The unusual features in this particular case were his age and the presence of hemolytic jaundice.

Definition and causes of jaundice Jaundice (icterus) refers to the yellow color of the skin, nail beds, and sclerae caused by deposition of bilirubin, secondary to increased bilirubin levels in the blood. There are three major forms of jaundice hemolytic jaundice, caused by massive lysis of red blood cells, releasing more heme than can be handled by the reticuloendothelial system obstructive jaundice, resulting from obstruction of the bile duct and hepatocellular jaundice, caused by damage to liver cells that decreases the liver s ability to take up and conjugate bilirubin. In addition, neonatal jaundice is caused by the low activity of hepatic glucuronylation of bilirubin, especially in premature infants. 

It is generally accepted that in normal subjects, most, but not necessarily all, of the bilirubin formed results from the breakdown of hemoglobin in the reticuloendothelial system. The bilirubin is then conjugated in the liver and excreted into the bile as a water-soluble pigment. The capacity of the liver to conjugate bilirubin is limited (W6), so that in cases of overproduction (e.g., hemolytic jaundice) free bilirubin will appear in the plasma. A similar result will be obtained if the ability of the liver to conjugate bilirubin is diminished (e.g., in the newborn infant). On the other hand, if the excretion of the bile is for some reason...

The deficit of this element leads to delay in crop maceration, as well as to different anemia, disease of bone systems and endemic ataxia of animal organisms. However, the excessive uptake and accumulation of copper in animals is accompanied by hemolytic jaundice, kidney disease, and by plant chlorosis.

In addition, there are some hepatic metabolic uses. Because hepatic glucuronyl transferase and the bilirubin-binding Y protein are increased by the barbiturates, phenobarbital has been used successfully to treat hyperbilirubinemia and kernicterus in the neonate. The nondepressant barbiturate phetharbital (A-phenylbarbital) works equally well. Phenobarbital may improve the hepatic transport of bihrubin in patients with hemolytic jaundice. 

The anemia is essentially hemolytic, i.e., the heme pigment is synthesized at normal rates but it is not used. The excess pigment is destroyed to yield bilirubin, and hemolytic jaundice develops. Consequently, the clinicopathological picture is that of a hypochromic hemolytic anemia. 

Jaundice may develop by three different mechanisms hemolytic jaundice results from the overproduction of bile pigments obstructive jaundice develops because of a block in the excretion mechanism and hepatic jaundice is due to impairment of the hepatic secretion of bile. 

Porphyrinuria may be defined as an increase of ether-soluble porphyrins, such as coproporphyrin, in the urine caused by various disturbances. Coproporphyrin III is said to predominate in lead and chemical poisoning, in aplastic anemia, poliomyelitis, and Hodgkin s disease. Coproporphyrin I is said to predominate in pernicious anemia, leukemia, hemolytic jaundice, nonalcoholic cirrhosis, obstructive jaundice, and infective hepatitis. Some of these effects have been considered in the sections on coproporphyrin and protoporphyrin.
