Hepatitis01:25

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...
Pulmonary Tuberculosis V01:28

Pulmonary Tuberculosis V

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...

Methods Of Healthcare Delivery System

At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is limited...
Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test01:22

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...
Standard Precaution01:26

Standard Precaution

Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

Area of Science:

  • Hepatology
  • Infectious Diseases
  • Public Health

Background:

  • Hepatitis B is a major cause of chronic liver disease in developing countries, affecting 5-15% of the population.
  • High prevalence is linked to insufficient infection control, with most infections occurring in childhood and early adulthood.
  • Co-infections (HIV, HDV, HCV), alcohol, and aflatoxin accelerate chronic Hepatitis B (CHB) progression in these regions.

Purpose of the Study:

  • To review the current landscape of Hepatitis B infection in developing countries.
  • To discuss challenges in CHB management, including treatment modifications and drug resistance.
  • To emphasize the importance of vaccination and appropriate treatment strategies.

Main Methods:

  • Literature review of Hepatitis B epidemiology and management in developing countries.
  • Analysis of factors influencing CHB progression and treatment efficacy.
  • Discussion of available therapeutic agents and challenges like drug resistance.

Main Results:

  • Hepatitis B infection is widespread, often presenting as advanced disease.
  • Treatment guidelines from developed countries may require adaptation for resource-limited settings.
  • Effective treatment initiation is suggested for patients with persistently elevated aminotransferase levels and high HBV DNA.

Conclusions:

  • Hepatitis B remains a significant public health issue in developing countries.
  • Tailored treatment protocols and accessible antiviral therapies are essential.
  • Universal vaccination programs are paramount for the long-term control of Hepatitis B.
