Summary
Two drug-induced hepatitis cases revealed hypersensitivity mechanisms. Naproxen caused cholestatic jaundice, while alpha-methyldopa led to liver cell necrosis, highlighting diagnostic challenges in drug-induced liver injury.
Area of Science:
- Hepatology
- Clinical Medicine
- Pharmacology
Background:
- Drug-induced liver injury (DILI) is a significant clinical concern.
- Hypersensitivity reactions are a known, yet complex, mechanism of DILI.
- Understanding diverse DILI presentations is crucial for accurate diagnosis and management.
Purpose of the Study:
- To present two distinct cases of drug-induced hepatitis.
- To elucidate the underlying hypersensitivity pathogenesis in these cases.
- To highlight the diagnostic and clinical management challenges posed by severe DILI.
Main Methods:
- Case report analysis of two patients with drug-induced hepatitis.
- Histopathological examination of liver biopsies.
- Clinical data review including symptoms, diagnosis, and treatment.
Main Results:
- Case 1 (Naproxen): Presented with severe cholestatic jaundice and a histological pattern of ductular cholestasis without inflammation.
- Case 2 (alpha-methyldopa): Characterized by extensive liver cell necrosis and portal inflammation.
- Both cases demonstrated a hypersensitivity-mediated pathogenesis.
Conclusions:
- Drug-induced hepatitis can manifest with diverse clinical and histological features.
- Hypersensitivity is a key mechanism in certain DILI cases.
- Prompt recognition and careful follow-up are essential for managing severe drug-induced liver injury.

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...
01:22Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test
In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...
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...
01:24Chronic 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...

01:25Chronic 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...
