Summary
Neonatal cholestasis due to Rh isoimmunization is rare. This case highlights immune-mediated cholangiolitis in a newborn with anti-E isoimmunization, responsive to corticosteroid therapy.
Area of Science:
- Neonatal cholestasis
- Immunology
- Hepatology
Background:
- Cholestasis in neonates is uncommon with Rh isoimmunization and typically self-resolves.
- Pathophysiology is often attributed to inspissated bile and hepatocellular injury.
Observation:
- A rare case of persistent cholestasis with cholangiolitis in a newborn with anti-E isoimmunization is presented.
- Immunohistochemical analysis and liver biopsy revealed CD8(+) lymphocytes damaging interlobular bile ducts.
Findings:
- The patient presented with conjugated hyperbilirubinemia and cholangiolitis.
- Liver biopsy confirmed immune-mediated damage to bile ducts.
Implications:
- Corticosteroid therapy (prednisolone) led to a significant decrease in bilirubin levels.
- Suggests an immune-mediated cholangiolitis as the cause of cholestasis in this rare condition.
- Highlights the potential role of immune responses in neonatal cholestasis associated with Rh isoimmunization.

01:20Cholecystitis
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...
01:17Chronic Bowel Disorders: Introduction
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...

The Rhesus (Rh) antigen is crucial in determining blood groups and ensuring compatibility during blood transfusions.
01:15Transcytosis of IgG
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...
