Physiologic jaundice generally lasts less than seven days. [1] The condition affects over half of babies in the first week of life. [1] Of babies that are born early about 80% are affected. [2] Globally over 100,000 late-preterm and term babies die each year as a result of jaundice. [4]
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.

When an infant is suspected to have hemolytic jaundice, abnormal morphologies of erythrocytes can be analyzed to find out the causes of hemolysis. [34] A Coomb's test should be performed, and end-tidal carbon monoxide concentration should be monitored to understand the rate of hemolysis in the infant's body. [35]
Around 80 to 99% of people with Dubin–Johnson syndrome have jaundice, [3] [4] abnormal urinary color, biliary tract abnormality, and conjugated bilirubinemia. [4] Around 30 to 79% of people with the disorder have abnormality of the gastric mucosa. [4] Other rare symptoms include fever and fatigue. [3]
Jaundice, also known as icterus, is a yellowish or greenish pigmentation of the skin and sclera due to high bilirubin levels. [3] [6] Jaundice in adults is typically a sign indicating the presence of underlying diseases involving abnormal heme metabolism, liver dysfunction, or biliary-tract obstruction. [7]
Symptoms of HFI include vomiting, convulsions, irritability, poor feeding as a baby, hypoglycemia, jaundice, hemorrhage, hepatomegaly, hyperuricemia and potentially kidney failure. [1] There are reported deaths in infants and children as a result of the metabolic consequences of HFI. Death in HFI is always associated with problems in diagnosis. [2]
When the total serum bilirubin increases over 95th percentile for age during the first week of life for high risk babies, it is known as hyperbilirubinemia of the newborn (neonatal jaundice) and requires light therapy to reduce the amount of bilirubin in the blood. Pathological jaundice in newborns should be suspected when the serum bilirubin ...
Most individuals with G6PD deficiency are asymptomatic.When it induces hemolysis, it is usually is short-lived. [5]Most people who develop symptoms are male, due to the X-linked pattern of inheritance, but female carriers can be affected due to unfavorable lyonization or skewed X-inactivation, where random inactivation of an X-chromosome in certain cells creates a population of G6PD-deficient ...
