Viral Hepatitis I: Introduction01:28

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...

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...

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...

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...
Hepatic Drug Excretion: Influencing Factors01:16

Hepatic Drug Excretion: Influencing Factors

The biliary system of the liver, crucial for bile secretion and drug excretion, comprises intrahepatic bile ducts that merge to form the common hepatic duct. This duct, carrying hepatic bile, combines with the cystic duct, draining the gallbladder and forming the common bile duct, which empties into the duodenum. Bile, produced by hepatic cells lining the bile canaliculi, is composed primarily of water, bile salts, pigments, electrolytes, and lesser amounts of cholesterol and fatty acids. Bile...
Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment01:08

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment

Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

Summary

Most published cost-effectiveness studies on antiviral hepatitis treatments show favorable results, suggesting potential publication bias. Increased scrutiny is needed when using these analyses for healthcare decisions.

Area of Science:

  • Pharmacoeconomics
  • Health Economics
  • Hepatitis Treatment Research

Background:

  • Cost-effectiveness analyses (CEA) evaluate treatment strategies comparing effectiveness and cost.
  • CEA results inform pharmacoeconomic decisions supporting specific treatment pathways.

Purpose of the Study:

  • To investigate publication bias in cost-effectiveness studies for antiviral hepatitis B and C treatments.
  • To determine if favorable cost-effectiveness results increase publication likelihood.

Main Methods:

  • Systematic literature search of original CEA studies (1987-2011) on antiviral hepatitis B/C treatment.
  • Independent data abstraction by two reviewers and contact with corresponding authors.

Main Results:

  • 71.4% of 77 studies reported cost-effectiveness ratios below $50,000/QALY; 59.7% were below $20,000/QALY.
  • 92.2% of studies reported favorable cost-effectiveness outcomes.
  • Non-US/European studies showed lower ratios; academic-funded studies were less likely to report ratios below $20,000/QALY.

Conclusions:

  • A high proportion of published CEA studies on antiviral hepatitis treatments report favorable results.
  • Potential publication bias exists, possibly due to researchers selecting studies with likely positive outcomes.
  • Greater awareness and critical evaluation are necessary when interpreting CEA for healthcare decision-making.
