Progressive intrahepatic cholestasis (Byler's disease): case report
Gut
|December 1, 1975
Summary
This study details a child with Byler disease, a progressive intrahepatic cholestasis. Findings suggest a bile acid secretion defect linked to microfilament changes in liver cells.
Area of Science:
- Hepatology
- Pediatric Gastroenterology
- Cell Biology
Background:
- Byler disease is a rare, progressive familial intrahepatic cholestasis.
- Intrahepatic cholestasis involves impaired bile flow within the liver.
- Electron microscopy is crucial for visualizing cellular structures in liver disease.
Observation:
- Clinical and laboratory data indicated progressive intrahepatic cholestasis in a child.
- Histological and histochemical analyses supported intrahepatic cholestasis.
- Electron microscopy revealed bile canalicular membrane interruptions, characteristic of Byler's disease.
Findings:
- A significant increase in pericanalicular and hepatocytic microfilamentous structures was observed.
- These findings suggest a primary disturbance in bile acid secretion contributes to cholestasis.
- Hypertrophy of pericanalicular microfilaments may indicate a role in the terminal biliary secretion step.
Implications:
- This case highlights the potential role of microfilaments in biliary secretion defects.
- Further research into bile acid transport and microfilament function could reveal new therapeutic targets for cholestatic liver diseases.
- Understanding these cellular processes is vital for diagnosing and managing pediatric liver conditions like Byler's disease.

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...

01:26Diseases of the Liver and Gallbladder
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 related to...

01:24Chronic Pancreatitis I: Introduction
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
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.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

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...
01:25Chronic Pancreatitis I: Introduction
Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...
01:21Chronic Pancreatitis II: Pathophysiology
Chronic pancreatitis is a progressive and irreversible inflammation of the pancreas, most often caused by long-term alcohol abuse, but it can also be related to ductal obstruction, smoking, or genetic factors.Chronic pancreatitis occurs when the pancreas is repeatedly exposed to harmful agents like alcohol, smoking, ductal obstruction, or genetic predisposition. These factors lead to the release of toxic metabolites and inflammatory cytokines, sustaining chronic inflammation in the pancreatic...
