People with GS predominantly have elevated unconjugated bilirubin, while conjugated bilirubin is usually within the normal range or is less than 20% of the total. Levels of bilirubin in GS patients are reported to be from 20 μM to 90 μM (1.2 to 5.3 mg/dl) [38] compared to the normal amount of < 20 μM. GS patients have a ratio of unconjugated ...
The high levels of bilirubin must be excreted into the bile by the liver, which may cause the formation of a pigmented gallstone, which is composed of calcium bilirubinate. Since these stones contain high levels of calcium carbonates and phosphate, they are radiopaque and are visible on x-ray. Hyperglycemia with concomitant low hemoglobin A1C ...
Common bile duct stone, also known as choledocholithiasis, is the presence of gallstones in the common bile duct (CBD) (thus choledocho-+ lithiasis). This condition can cause jaundice and liver cell damage. Treatments include choledocholithotomy and endoscopic retrograde cholangiopancreatography (ERCP).
There are additional rare causes of hereditary hyperbilirubinemia like Lucey-Driscoll syndrome and Heme Oxygenase-1 Deficiency. [1] Both Gilbert syndrome and Crigler-Najjar syndrome cause an elevated unconjugated bilirubin level due to mutations in the UGT1A1 gene, which conjugates bilirubin within liver cells so it can be excreted.
Neonatal cholestasis refers to elevated levels of conjugated bilirubin identified in newborn infants within the first few months of life. [1] Conjugated hyperbilirubinemia is clinically defined as >20% of total serum bilirubin or conjugated bilirubin concentration greater than 1.0 mg/dL regardless of total serum bilirubin concentration.

If one or more gallstones block the bile ducts and cause bilirubin to leak into the bloodstream and surrounding tissue, jaundice and itching may also occur. In this case, liver enzyme levels are likely to be raised. [16] Often, gallbladder attacks occur after eating a heavy meal. Attacks are most common in the evening or at night. [17]
Treatment depends on the type and cause of the hemolytic anemia. [2] Symptoms of hemolytic anemia are similar to other forms of anemia (fatigue and shortness of breath), but in addition, the breakdown of red cells leads to jaundice and increases the risk of particular long-term complications, such as gallstones [4] and pulmonary hypertension.

Sickle cell disease, in which a mutation in the globin gene causes the formation of sickle hemoglobin. [2] This disease is marked by the manifestation of chronic compensated hemolytic anemia, with laboratory findings not limited to unconjugated hyperbilirubinemia but also elevated serum lactate dehydrogenase and low serum haptoglobin.
