Insights

Hepatitis B vaccination significantly reduced infections in infants and globally. Continued understanding of hepatitis B virus (HBV) is crucial due to vaccine hesitancy.

Area of Science:

  • Hepatology
  • Infectious Diseases
  • Vaccinology

Background:

  • Hepatitis B virus (HBV) causes acute and chronic liver disease globally.
  • Infant HBV infection leads to chronic disease, cirrhosis, and liver cancer in 90% of cases.
  • Universal infant vaccination has drastically cut perinatal transmission in the US and HBV incidence in Asia.

Purpose of the Study:

  • To underscore the importance of understanding hepatitis B epidemiology, transmission, screening, and prevention.
  • To inform pediatric health care providers amidst evolving vaccine guidance and rising hesitancy.

Main Methods:

  • Epidemiological review of hepatitis B virus (HBV) infection.
  • Analysis of vaccination impact on HBV incidence and transmission.
  • Assessment of current challenges in hepatitis B prevention.

Main Results:

  • Universal infant vaccination programs have led to significant reductions in hepatitis B transmission.
  • Hepatitis B vaccination is a cornerstone of preventing chronic liver disease and hepatocellular carcinoma.
  • Vaccine hesitancy poses a threat to sustained control of hepatitis B.

Conclusions:

  • Despite successes, ongoing vigilance and education on hepatitis B virus (HBV) are essential.
  • Pediatric health care providers must remain informed about HBV epidemiology and prevention strategies.
  • Addressing vaccine hesitancy is critical to maintaining progress against hepatitis B.

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...

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...
Chronic Pancreatitis I: Introduction01:24

Chronic 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...
Chronic Pancreatitis I: Introduction01:25

Chronic 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...
