Insights

This study found no cases of occult Hepatitis B virus (HBV) infection among patients with chronic Hepatitis C virus (HCV) infection. Further research is needed to understand occult HBV prevalence in this population.

Area of Science:

  • Hepatology
  • Virology
  • Infectious Diseases

Background:

  • Occult Hepatitis B virus (HBV) infection is defined by the presence of HBV DNA in individuals negative for Hepatitis B surface antigen (HBsAg).
  • Chronic Hepatitis C virus (HCV) infection is a significant global health concern, often co-existing with other viral hepatitis infections.

Purpose of the Study:

  • To determine the prevalence of occult HBV infection in patients diagnosed with chronic HCV infection.
  • To investigate the co-infection patterns of HBV and HCV in an outpatient setting.

Main Methods:

  • A cross-sectional study was conducted over one year (May 2018-May 2019).
  • Patients with confirmed chronic HCV RNA by PCR were recruited.
  • Blood samples were tested for HBsAg; HBsAg-negative individuals were further tested for HBV DNA using real-time PCR.

Main Results:

  • A total of 217 patients with chronic HCV infection were included.
  • All 217 patients tested negative for both HBsAg and HBV DNA.
  • No instances of occult HBV infection were detected in this cohort of chronic HCV patients.

Conclusions:

  • Occult HBV infection was not detected in patients with chronic HCV infection seeking treatment in this study.
  • The findings suggest a low prevalence or absence of occult HBV in this specific patient group.
  • Further studies with larger cohorts and diverse populations are warranted to confirm these results.

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...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

Hepatic Drug Excretion: Enterohepatic Cycling01:17

Hepatic Drug Excretion: Enterohepatic Cycling

Enterohepatic cycling involves the active secretion of drugs and their metabolites into the bile via transporters in the canalicular membrane of hepatocytes. This secretion is an integral part of the digestive process, releasing these substances into the gastrointestinal (GI) tract.
Post-release drugs and metabolites can be reabsorbed into the body from the intestine. For conjugated metabolites like glucuronides, reabsorption requires enzymatic hydrolysis by intestinal microflora. This...
