Summary
This case study highlights a patient initially diagnosed with autoimmune hepatitis (AIH) who later developed primary biliary cholangitis (PBC). Repeat liver biopsy confirmed the diagnostic shift, emphasizing its importance in managing chronic liver disease.
Area of Science:
- Hepatology
- Immunology
- Gastroenterology
Background:
- Autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC) are chronic liver diseases with distinct pathologies.
- Accurate diagnosis and monitoring are crucial for effective management of these conditions.
- Disease progression or transformation can occur, necessitating reassessment.
Purpose of the Study:
- To describe a case of a patient initially diagnosed with AIH who later presented with features of PBC.
- To evaluate the utility of repeat liver biopsy in diagnosing evolving liver conditions.
- To assess the treatment response to ursodeoxycholic acid and pemafibrate in a patient with suspected PBC.
Main Methods:
- A 70-year-old female patient with a history of AIH was monitored over 12 years.
- Diagnostic tools included antinuclear antibody testing, liver enzyme monitoring, alkaline phosphatase levels, and serial liver biopsies.
- Treatment involved prednisolone (PSL), followed by adjustments including ursodeoxycholic acid and pemafibrate.
Main Results:
- Initial diagnosis of AIH was based on serological and biopsy findings, treated with PSL.
- After 12 years, repeat biopsy revealed PBC characteristics, with no signs of AIH.
- Treatment modification led to improved liver enzyme and alkaline phosphatase levels.
Conclusions:
- Liver biopsy is a valuable tool for diagnosing changes in liver conditions, even in patients with established AIH or PBC.
- This case illustrates a potential diagnostic evolution from AIH to PBC.
- Therapeutic adjustments including ursodeoxycholic acid and pemafibrate can be effective in managing PBC.

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...
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...
01:24Chronic 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...

01:17Gastritis-II: Pathophysiology
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

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...

01:24Cirrhosis II: Pathophysiology
Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...
