The most common cause of ALF in the neonatal period is gestational alloimmune liver disease (GALD), formerly known as neonatal hemochromatosis (NH). This is followed by viral infections, metabolic diseases, hemophagocytic lymphohistiocytosis (HLH), and other rare causes (4–6, 10).
What is the mortality rate of acute liver failure?
Acute liver failure is a condition that is defined as a sudden, complete, or nearly complete loss of liver functions without any previous liver disease, usually accompanied by encephalopathy, which can be reversible, but with a mortality rate of 55–70% . Acute liver failure newborns is an acute liver failure in the first 28 days of life. The Pediatric Acute Liver Failure Working Group identified the presence of coagulopathy as the main finding for the identification of acute liver failure in childhood following vitamin K administration. Although the incidence of acute liver failure is reported to be 17/100 000 in all ages, its incidence is not known exactly in newborn and childhood. The most common cause of acute liver failure in the newborn period is the gestational alloimmune liver disease that was previously known as neonatal hemochromatosis. This is followed by viral infections, metabolic diseases, hemophagocytic lymphohistiocytosis, and other rare causes. In the neonatal period, acute liver failure is a rare condition with a high mortality rate. For this reason, the vital signs of the patients should be closely monitored and supportive treatments should be planned according to the follow-up and the etiology of the disease should be clarified urgently. In this process, acyclovir treatment until herpes simplex virus infection is excluded and lactose-free feeding until galactosemia is excluded are recommended as life-saving treatments. In the literature, since there is a limited number of studies related to neonatal acute liver failure, prospective studies investigating the factors affecting treatment and prognosis are needed.
What is tyrosinemia caused by?
Tyrosinemia is an autosomal recessive disorder caused by enzyme deficiencies in tyrosine amino acid metabolism. Tyrosine is an amino acid involved in catecholamine, thyroid hormone, and melanocyte synthesis. There are three types of hereditary tyrosinemia. Fumaryl acetoacetate hydroxylase enzyme is deficient in type 1 tyrosinemia (hepatorenal type). The liver, kidney, and nervous system are affected as a result of this enzyme deficiency. Patients usually present with restlessness, nausea, vomiting, jaundice, growth restriction, hepatomegaly, electrolyte imbalance, metabolic acidosis, renal tubular dysfunction, hypoglycemia, bleeding diathesis, and ALF in the early childhood and neonatal period. Succinylacetone in urine in suspected newborns; Diagnosis can be made by demonstrating reduced fumaryl acetoacetate hydroxylase enzyme activity in lymphocyte, erythrocyte, or liver tissue, and patients can be treated with appropriate nutrition and vitamin support (5, 20).
What percentage of nalf is caused by a virus?
Viral infections are held responsible for 20–30% of NALF (5, 6). Viruses are transmitted to newborns at or after birth. For this reason, patients are usually normal in the prenatal period, and present symptoms in the 1st–2ndweeks of life. Preterm babies are more susceptible to infections than term babies due to low levels of antibodies transmitted from the mother and their immune system is not yet developed. Transaminase levels are extremely high (>1000 U/L) due to massive necrosis of the liver and hepatosplenomegaly is common. Diagnosis is made by demonstrating the agent with polymerase chain reactions in blood and other body fluids, nasal swab, urine, and stool samples or by the production of the agent in fibroblast cultures (6, 11).
What is the ALF of a person?
Acute liver failure (ALF) is a condition that is defined as a sudden, complete, or almost complete loss of liver function without any previous liver disease, usually accompanied by encephalopathy, can be reversible, but with a mortality rate of 55–70% (1–4). It is defined as the presence of acute damage without significant fibrosis of the liver. Acute liver failure (NALF) in the newborns is ALF seen in the first 28 days of life. ALF in adults is defined as the detection of encephalopathy within eight weeks of the development of jaundice in a person without previously known liver disease (5), but it is difficult to detect hepatic encephalopathy in childhood, especially in the neonatal period. For this reason, the Pediatric Acute Liver Failure Study Group has determined the presence of coagulopathy [prothrombin time ≥20 seconds after vitamin K administration or an international normalized ratio (INR) ≥2] as the main finding for the definition of ALF in childhood. INR value may be up to 2 in healthy newborns and INR ≥2 in premature babies may be normal. Therefore, the presence of coagulopathy in the NALF definition is accepted as INR≥3 (3–7). Although the prevalence of acute liver failure at all ages is reported as 17/100 000, its prevalence in the newborn and childhood period is not fully known (2).

Urine appears dark in infants with liver disease because of the build-up of bilirubin in the bloodstream that filters into the urine. A urine test can be performed to detect the presence of bilirubin in the urine.
Why is my stool pale?
This prevents bilirubin from getting into the digestive tract and causes the stool to appear unusually pale. Light-colored, gray or clay-colored stools, referred to as acholic stools, are an indication of a liver problem in infants. Normally, babies excrete bilirubin into their digestive tract, giving their stool a yellowish color.
Why do babies have pale stools?
Normally, babies excrete bilirubin into their digestive tract, giving their stool a yellowish color.
How long does jaundice last?
Jaundice that persists beyond two weeks is worrisome. A simple blood test, known as a bilirubin test, can determine if prolonged jaundice is due to an underlying liver problem.

When infants are born with liver disease, damage slowly increases over the first few weeks of life. As that happens, the liver becomes enlarged . This appears as a hard swelling in the upper abdomen that can be felt on a routine physical exam.
What is the AST level?
Elevated ALT or aspartate aminotransferase (AST) above the upper limit of normal (ULN; considered to be 30 international units/L for men and 20 for women, with range varying between different labs) in a population without identifiable risk factors should be assessed by physicians, as it is associated with increased liver-related mortality.3However, there are some circumstances in which elevations in liver enzymes are physiological — for example, alkaline phosphatase (ALP) levels may be increased during the third trimester of pregnancy, and both AST and ALT may increase with vigorous exercise.4,5
What is the AST level in alcoholic hepatitis?
Generally, the enzymes in alcoholic hepatitis are only moderately elevated. The AST seldom exceeds 8–10 × the ULN and the ALT 5 × the ULN; however, in severe acute alcoholic hepatitis the serum bilirubin can rise significantly. ALT levels may even be normal in alcoholic liver disease, and thus a normal serum ALT concentration does not exclude an alcoholic liver disorder. This pattern is thought to be the result of two mechanisms. Most chronic alcoholics are deficient in pyridoxal 5′-phosphate (vitamin B6), which is a necessary coenzyme for both ALT and AST synthesis. Deficiency of pyridoxal 5′-phosphate decreases ALT synthesis to a greater extent than AST synthesis.19Additionally, alcohol itself stimulates the synthesis and release of mitochondrial AST, thereby increasing the AST: ALT ratio.19

What is the prevalence of hepatitis C?
Incidence of hepatitis C infection is much higher in patients with ALT levels greater than 40 U/L, as compared to the estimated incidence of 1.8% in the general population. 13Incidence of hepatitis B virus (HBV) infection is between 0.2% and 0.9% in the general United States’ population, which is comparatively less common than hepatitis C virus (HCV) infection.13However, in patients who have emigrated from endemic areas of the world, the prevalence of HBV infection in the United States can be as high as 20%.13Risk factors like intravenous drug use, sexual history, travel to foreign countries, occupation, etc. can dramatically increase the prevalence of both viruses. Since these two viruses have such a high prevalence, some clinicians recommend early and empiric testing for HBV and HCV, even in the absence of risk factors for patients presenting with mildly elevated hepatocellular enzymes.21,22Hepatitis E, although uncommon in the United States, should be considered when there is a history of travel to an endemic area (i.e. Central America and Asia).
