Abstract

Insights

Familial Mediterranean fever (FMF) can affect the liver in children, causing conditions like hepatitis and cirrhosis. Early recognition and colchicine treatment are crucial for managing FMF-related liver involvement.

Area of Science:

  • Pediatric Gastroenterology
  • Hepatology
  • Rheumatology

Background:

  • Familial Mediterranean fever (FMF) is an autoinflammatory disease characterized by recurrent febrile attacks.
  • Chronic inflammation in FMF, driven by cytokines, can lead to liver injury, including hepatitis and cirrhosis.
  • The role of liver involvement in pediatric FMF cases requires further investigation.

Purpose of the Study:

  • To investigate the prevalence and characteristics of liver involvement in children diagnosed with Familial Mediterranean fever.
  • To identify potential risk factors or genetic associations with liver disease in pediatric FMF patients.

Main Methods:

  • A cohort of 58 pediatric patients with Familial Mediterranean fever was studied.
  • Detailed examination of patients with confirmed liver involvement.
  • Analysis of demographic factors, laboratory findings, and genetic mutations (M694V).

Main Results:

  • Liver involvement was observed in 18.9% (11/58) of pediatric FMF patients.
  • Diagnoses included Budd-Chiari syndrome, chronic hepatitis/cirrhosis, and acute hepatitis.
  • Colchicine treatment led to clinical and laboratory improvement in all affected patients.

Conclusions:

  • Familial Mediterranean fever should be considered in pediatric cases of unexplained hepatitis or cirrhosis, particularly in endemic areas.
  • Pediatric hepatologists play a key role in diagnosing and managing FMF-associated liver disease.
  • Effective management with colchicine highlights the importance of early FMF diagnosis.

Diseases 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...

Gastritis-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...

Gastritis II: Pathophysiology

The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...
Cholecystitis01:20

Cholecystitis

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...
Cirrhosis II: Pathophysiology01:24

Cirrhosis 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...

Chronic 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...
