Diseases of the Liver and Gallbladder01:26

Diseases of the Liver and Gallbladder

467
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...

Chronic Pancreatitis I: Introduction

72
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...

CNS Depressants: Alcohol and Nicotine

174
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

Liver Physiology01:30

Liver Physiology

429
The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of  70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...

Liver Regeneration01:24

Liver Regeneration

3.2K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Esophageal Varices-I: Introduction01:24

Esophageal Varices-I: Introduction

73
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

Summary

Alcoholic liver disease (ALD) is a growing concern in Japan, with alcoholic cirrhosis becoming the leading cause. Effective management requires alcohol abstinence, social support, and nutritional care.

Area of Science:

  • Hepatology
  • Gastroenterology
  • Public Health

Background:

  • Alcoholic liver disease (ALD) results from excessive alcohol consumption, manifesting in various forms and severities.
  • Despite declining overall alcohol consumption in Japan, the prevalence of heavy drinking remains stable, leading to shifting disease demographics.
  • A 2023 national survey revealed alcoholic cirrhosis now constitutes 35% of cirrhosis cases, exceeding hepatitis C virus-related cirrhosis.

Purpose of the Study:

  • To analyze the current trends and leading causes of cirrhosis in Japan.
  • To highlight the increasing burden of alcoholic cirrhosis.
  • To underscore the need for comprehensive management strategies for ALD.

Main Methods:

  • Analysis of national survey data on cirrhosis prevalence.
  • Comparison of etiological factors for cirrhosis, including alcohol and hepatitis C virus.
  • Review of current treatment paradigms and ongoing clinical trials for ALD.

Main Results:

  • Alcoholic cirrhosis has surpassed hepatitis C virus-related cirrhosis as the primary cause of cirrhosis in Japan.
  • The proportion of alcoholic cirrhosis has risen to 35% in the latest national survey.
  • While overall ALD patient numbers are decreasing, severe forms like cirrhosis are increasing.

Conclusions:

  • Alcohol abstinence is the cornerstone of ALD treatment.
  • Integrated social, medical, and nutritional interventions are crucial for managing alcohol dependence and ALD.
  • Further research and clinical trials, particularly in Western countries, are investigating various stages of ALD.
