Hyperbilirubinemia Research Papers

Jaundice can be explained using a proximate explanation as a yellowing of the skin and eyes due to excess bilirubin. Bilirubin is a product of the breakdown of haemoglobin. It is made water soluble in the liver before being excreted into bile. [6] So bilirubin appears to be a useless waste product. It is only by looking at the evolutionary explanation for it that we understand its true value. Bilirubin is an antioxidant that protects against oxidative damage that leads to aging. High bilirubin levels have similarly been associated with a lower rate of heart attacks. Haem is first converted to biliverdin, then a reaction catalysed by biliverdin reductase produces bilirubin. Dangerous oxygen radicals react with bilirubin, preventing cell death.

One of these symptoms is jaundice, which is characterized by yellowish skin and eyes because of an inability of the liver to remove bilirubin from the blood. Patient with cirrhosis also suffering from itching, due to deposited bile's products in the skin. This patient also suffers from accumulation of fluid in legs that is called edema. As a result of the blockage of blood flow via the liver, fluid accumulation in abdomen which is worsen by the decrease in protein production. Other symptoms include fatigue, weakness, loss of appetite, weight loss and nausea. As the disease progress, complications may develop ,such as varices that happens with cirrhosis patient when the blood flow through the liver slows, so the blood from intestine go back to the vessels of the stomach and esophagus, these vessels are not meant to carry this much of blood so they dilate (varices), with increasing

The liver produces bile which contains conjugated bilirubin. It is then sent to the gallbladder, and it has to be excreted properly from there. However, the gallstones are blocking the way, which makes it hard for the bilirubin to get out, and results in a build-up. This leads to jaundice, which occurs when one has and excessive amount of bilirubin.

Bilirubin (which causes the yellow color) from these broken down cells builds up in the system causing jaundice.

Your urobilinogen count was at a normal range and there were no indications of liver disease. If there are any other terms that are unclear, do not hesitate to ask and I would be happy to help.

She looked jaundiced (yellowing of her body tissues), which is due to accumulation of bilirubin, a blood product, due to impaired excretion by the liver (7). Her mental status was indicative of hepatic encephalopathy, with orientation to only person and place, and did not know the date or time. Abdominal examination exposed moderate tenderness, normal bowel sounds, and severe ascites. Ascites is an abnormal buildup of fluid in the abdominal cavity, and is often caused by blood backed up in the hepatic portal vein going into the liver, due to cirrhosis. The backed up blood fills with byproducts that cannot be processed by the diseased liver, which shuts down the kidneys. The disabled kidneys cause a buildup of fluid, which leaks out of the vasculature and into the abdominal cavity (8). Diseased livers also often produce less albumin, a protein in the blood that helps keep fluid in the vasculature. When the albumin levels drop, fluid leaves the blood, entering the body as edema, or swelling, which was moderately visible in her feet (9). Upon rectal examination, hemorrhoids were noted to be present, but are not considered a pathology, simply an anatomical structure that exists in most people from a young age (10). A stool sample was taken, and tested positive for blood with a hemoccult test.

parasites in the liver which can block the excretion or removal of bilirubin from the body

Pernicious anemia is typically caused by a weakened stomach lining, or an autoimmune condition where the body attacks the intrinsic factor or the stomach lining. Biermer’s disease is rarely hereditary, this is called Congenital Pernicious anemia this is where babies do not make enough intrinsic factor or there is something going wrong with the absorption process in the small intestine. The prevalence of Pernicious anemia is estimated to be diagnosed in 1/769 people while Congenital Pernicious anemia is estimated to be

As explained by Dr. Richard Weisiger, bilirubin is produced during the breakdown of Hgb and other hemoproteins, and it is filtered out by the liver. Hyperbilirubinemia occurs when the liver cannot filter the bilirubin from the blood fast enough and the bilirubin is absorbed into tissues causing jaundice.

In mild cases, treatment is usually not needed. In severe cases, your child may need to be given red blood cells through an intravenous (IV) line (packed red blood cell transfusion).

Pernicious anemia is a condition in which the body fails to make enough healthy red blood cells because there is a deficiency of vitamin B12. Vitamin B12 is a nutrient that the body needs in order to make healthy red blood cells and to keep the nervous system working properly. Individuals with pernicious anemia can’t absorb enough vitamin B12 from foods because they lack intrinsic factor (IF), a protein made in the stomach that is necessary for the absorption of vitamin B12. A lack of this protein leads to a deficiency of vitamin B12. ( ) The decreased absorption of vitamin B12 from the gastrointestinal tract that causes this condition is believed to be the result of an autoimmune process which makes the body’s immune system attack the lining of the stomach. Normally, vitamin B12 binds to intrinsic factor in the stomach to help ease its absorption later when digestive products pass through the small intestines. The autoimmune process attacks the IF protein resulting in lower IF levels in stomach secretions, therefore, causing vitamin B12 to not be absorbed. ( )

Investigating haemoglobin (Hb) concentration in blood samples using the haemoglobincyanide method and in foetal haemoglobin samples

Diamond Blackfan anemia (DBA) is a rare genetic disease that causes defects in the ribosomal structure (Farber, 2016). The disease stems from a decrease in the production of erythroid precursors in the bone marrow, which results in an extremely low red blood cell count. Due to the reduction in the production of erythrocytes, most individuals diagnosed with this disease develop an array of issues that can be life threatening such as a predisposition to cancer and bone marrow failure. Within the first year of life, most symptoms of DBA will appear in most individuals (Ellis, 2014). The importance of understanding the genetics of DBA remains a priority in reducing the number of infants affected by a detrimental hereditary blood disorder.

This keeps up for a few days and you begin to feel a loss of appetite as well as nausea. A low grade fever between 100 °f - 102 °f is present. A pain and discomfort in the abdomen above the liver is also common, due to enlargement of the liver. After a few days of torture, a person’s urine becomes darker than usual and then jaundice, (a yellowish discoloration of the skin) appears. Jaundice and the dark urine indicate that liver is not functioning properly in removing a reddish-yellow pigment called bilirubin from the blood.
