Meropenem-induced vanishing bile duct syndrome
Pharmacotherapy
|September 4, 2010
Summary
Vanishing bile duct syndrome (VBDS) is a rare liver disorder. This case study suggests the antibiotic meropenem may cause VBDS, highlighting the need for vigilance in diagnosing drug-induced liver injury.
Area of Science:
- Hepatology
- Pharmacology
- Toxicology
Background:
- Vanishing bile duct syndrome (VBDS) is a rare condition characterized by the destruction of intrahepatic bile ducts, leading to cholestasis.
- The exact mechanisms of biliary epithelial cell damage in VBDS are not fully understood, but various etiologies, including drug-induced causes, have been reported.
Observation:
- A 60-year-old woman developed jaundice and pruritus three weeks after initiating meropenem for a brain abscess.
- Clinical presentation and diagnostic tests indicated mixed hepatocellular and cholestatic liver injury, with other causes of cholestasis ruled out.
Findings:
- A liver biopsy confirmed the absence of bile ducts, consistent with VBDS.
- The Naranjo scale indicated a probable relationship between meropenem use and the development of VBDS.
- Liver function tests improved several months after discontinuing meropenem.
Implications:
- This case suggests meropenem as a potential cause of drug-induced vanishing bile duct syndrome.
- Clinicians should maintain a high index of suspicion for VBDS in patients on meropenem presenting with prolonged cholestasis.
- Considering VBDS is crucial, especially after excluding more common causes of liver injury.

01:28Esophageal Varices-II: Clinical Features and Management
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol abuse, or...

01:26Endoscopic Procedures V: ERCP
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

01:11Pyloric Obstruction
Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...
