Summary
Neonatal cholestasis, often caused by biliary atresia, requires better diagnostic tools. Research aims to clarify the causes and develop improved treatments for this infant liver disease.
Area of Science:
- Pediatrics
- Hepatology
- Medical Genetics
Background:
- Neonatal cholestasis affects 1 in 2500 term infants, with biliary atresia being a common cause.
- Premature infants have a higher incidence of cholestasis.
- The exact causes of biliary atresia and α1-antitrypsin deficiency-related liver disease remain unclear.
Purpose of the Study:
- To investigate the etiology and pathogenesis of neonatal cholestasis.
- To explore non-invasive diagnostic tools for differentiating biliary atresia.
- To advance understanding of genetic cholestatic liver diseases.
Main Methods:
- Review of current literature on neonatal cholestasis.
- Analysis of findings in biliary atresia, α1-antitrypsin deficiency, Alagille's syndrome, and progressive familial intrahepatic cholestasis.
- Discussion of diagnostic approaches including liver biopsy.
Main Results:
- Biliary atresia etiology is unclear, hindering non-surgical treatment development.
- Pathogenesis of α1-antitrypsin deficiency liver disease requires further clarification, especially regarding disease manifestation in a minority of individuals.
- Molecular biology has improved understanding of genetic cholestatic diseases, but genotype-phenotype correlations are complex.
Conclusions:
- Further research is needed for non-invasive diagnostics in neonatal cholestasis.
- Clarifying disease mechanisms is crucial for developing novel therapeutic strategies.
- A structured management approach, including liver biopsy for suspected biliary atresia, is recommended.

29
Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...

Jaundice, or icterus, is the yellow discoloration of the skin, sclerae, and mucous membranes. It happens when plasma bilirubin levels rise above 2.5-3 mg/dL, leading to bilirubin deposition in tissue.Bilirubin is a byproduct of hemoglobin degradation. In macrophages, hemoglobin breaks down into globin and heme. Globin is converted into amino acids, while heme is turned into biliverdin by heme oxygenase, which is then reduced to unconjugated bilirubin by biliverdin reductase.Unconjugated...

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

01:15Transcytosis of IgG
3.4K
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

01:20Inborn Errors of Metabolism
1.1K
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...
