Insights

Hepatitis D (HDV) infection is highly prevalent in Hepatitis B surface antigen (HBsAg)-positive patients in Southern Pakistan. This indicates a critical need for effective preventive measures against HDV in the region.

Area of Science:

  • Hepatology
  • Virology
  • Public Health

Background:

  • Hepatitis B virus (HBV) infection is a global health concern.
  • Hepatitis D virus (HDV) is a unique RNA virus that requires HBV for replication, leading to more severe liver disease.
  • Estimating HDV prevalence in HBV-infected populations is crucial for targeted interventions.

Purpose of the Study:

  • To determine the prevalence of Hepatitis D virus (HDV) infection among patients positive for Hepatitis B surface antigen (HBsAg).
  • To assess the clinical status and viral markers in HBsAg-positive patients in liver clinics in Southern Pakistan.

Main Methods:

  • A cross-sectional study was conducted involving 362 HBsAg-positive patients from liver clinics in Karachi and Jacobabad between October 2007 and March 2008.
  • Patients were tested for HBV DNA, HDV RNA (by PCR), HBeAg, and anti-HDV antibodies.
  • Clinical evaluation included physical examination, routine biochemical tests, and abdominal ultrasound.

Main Results:

  • Out of 362 patients, 212 (58.6%) tested positive for anti-HDV antibodies.
  • HDV RNA was detected in 30 (46.2%) of the 65 anti-HDV positive patients tested.
  • Higher HDV antibody prevalence was observed in specific areas of Southern Pakistan (e.g., Kashmore 69.23%, Jacobabad 67%).
  • Positive HDV antibody status was significantly associated with more severe and advanced liver disease (p < 0.0001).

Conclusions:

  • Southern Pakistan exhibits an extremely high prevalence of Hepatitis D among HBsAg-positive patients.
  • The findings suggest Pakistan may be among the regions with the highest HDV prevalence globally.
  • Urgent implementation of effective preventive strategies is essential to control HDV transmission.

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...

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 the...

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...

Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow

Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug binding...

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
