Insights
Jaundice in infants can signal serious liver conditions like alpha-1 antitrypsin deficiency. Early, thorough diagnosis is vital for timely treatment of severe infantile cholestasis.
Area of Science:
- Pediatric Gastroenterology and Hepatology
- Genetic Metabolic Disorders
Background:
- Neonatal jaundice is common, but prolonged conjugated hyperbilirubinemia necessitates investigation for underlying liver diseases.
- Alpha-1 antitrypsin deficiency is a leading genetic cause of pediatric liver disease and liver transplantation.
Observation:
- Presents an unusual case of severe infantile cholestasis and rapid decompensation within the first four months of life.
- The infant exhibited symptoms indicative of a serious underlying condition requiring prompt medical attention.
Findings:
- Diagnosed with alpha-1 antitrypsin deficiency, a genetic disorder affecting the liver.
- The condition led to severe cholestasis and rapid deterioration, highlighting the genetic basis of infantile liver disease.
Implications:
- Emphasizes the critical need for timely and in-depth diagnostic analysis in cases of prolonged neonatal cholestasis.
- Highlights alpha-1 antitrypsin deficiency as a key consideration in the differential diagnosis of infantile cholestatic liver disease.
- Underscores the importance of early diagnosis for initiating appropriate and potentially life-saving interventions.
Abstract:
Jaundice in the newborn period can be physiologic and is often due to benign causes. Jaundice due to conjugated hyperbilirubinemia extending beyond the second week of life may be an early sign of several cholestatic or metabolic liver diseases, and it requires logical and timely analysis so that specific treatments can be initiated. Alpha-1 antitrypsin deficiency is the most common genetic cause of pediatric liver disease and transplantation, and it must be considered when evaluating cholestatic infants. Here, we present an unusual case of alpha-1 antitrypsin deficiency with severe infantile cholestasis and rapid decompensation in the first 4 months of life, where in-depth but timely diagnosis was crucial for the appropriate intervention to take place.

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.

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...
Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
