Diseases of the Liver and Gallbladder

537
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...

Aldehydes and Ketones with Alcohols: Hemiacetal Formation

6.2K
Similar to water, alcohols can add to the carbonyl carbon of the aldehydes and ketones. The addition of one molecule of alcohol to the carbonyl compound forms the hemiacetal or half acetal. As depicted below, in a hemiacetal, the carbon is directly linked to an OH and OR group.

Chronic Pancreatitis I: Introduction

89
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...

Acute Pancreatitis I: Introduction01:27

Acute Pancreatitis I: Introduction

360
Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

Summary

Recurrent alcohol-associated hepatitis (RAH) is common and more severe, increasing mortality. Patients surviving alcohol-associated hepatitis (AH) need intensive therapy for alcohol use disorder to prevent RAH.

Area of Science:

  • Hepatology
  • Gastroenterology
  • Addiction Medicine

Background:

  • Alcohol-associated hepatitis (AH) survivors frequently relapse.
  • Clinical features, risk factors, and outcomes of recurrent AH (RAH) are not well defined.

Purpose of the Study:

  • To investigate the incidence, risk factors, clinical course, and prognostic implications of RAH.

Main Methods:

  • A registry-based study of 1118 patients with AH across 28 Spanish hospitals (2014-2021).
  • Cox regression analysis for risk factors.
  • Kaplan-Meier curves and log-rank tests for survival analysis.

Main Results:

  • 11% of patients developed RAH (incidence 22% in those resuming alcohol use).
  • Risk factors for RAH included age <50, heavy alcohol use, and prior liver decompensation.
  • RAH cases were more severe (higher MELD, more ACLF/HE) and associated with lower abstinence rates and higher long-term mortality (39% vs. 21%).

Conclusions:

  • Recurrent alcohol-associated hepatitis is common, clinically aggressive, and significantly increases mortality.
  • Intensified alcohol use disorder therapy is crucial for AH survivors to prevent RAH.
