Insights

Most adults clear acute hepatitis B (AHB) within six months. Lower baseline hepatitis B surface antigen (HBsAg) and higher antibody to hepatitis B core antigen (anti-HBc) predict clearance, identifying patients at risk for chronic infection.

Area of Science:

  • Hepatology
  • Virology
  • Immunology

Background:

  • Acute hepatitis B (AHB) is typically self-limiting in adults, with most patients achieving hepatitis B surface antigen (HBsAg) clearance within six months.
  • Understanding factors influencing chronic outcomes in AHB is crucial for patient management.

Purpose of the Study:

  • To investigate the proportion of adult AHB patients who do not achieve HBsAg clearance within six months.
  • To identify factors influencing HBsAg clearance in adult AHB patients.

Main Methods:

  • A cohort of 126 adult AHB patients was analyzed retrospectively.
  • Multivariate regression analysis was employed to determine factors associated with HBsAg clearance.

Main Results:

  • 11.1% of patients did not achieve HBsAg clearance within six months; this reduced to 4.0% after one year.
  • Lower baseline HBsAg levels (≤250 IU/mL) and higher antibody to hepatitis B core antigen (anti-HBc) levels were significantly associated with HBsAg clearance.
  • Anti-HBc remained an independent predictor of HBsAg clearance across different HBsAg subgroups.

Conclusions:

  • Baseline HBsAg and anti-HBc levels can help identify adult AHB patients at risk of developing chronic infection.
  • Early identification of at-risk patients allows for targeted monitoring and potential intervention strategies.

Stages of Infection01:26

Stages of Infection

Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

Acute Pancreatitis II: Clinical Manifestations and Management01:30

Acute Pancreatitis II: Clinical Manifestations and Management

Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

Esophageal Varices-II: Clinical Features and Management

Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

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...

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Gastritis III: Clinical Manifestations and Management

The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
