Summary
Practitioners are aware of direct-acting antiviral (DAA) therapies for hepatitis C virus (HCV) but may increase referrals to specialists. Education is crucial to prevent inappropriate DAA use.
Area of Science:
- Hepatology
- Infectious Diseases
- Clinical Pharmacy
Background:
- Current hepatitis C virus (HCV) therapies have suboptimal response rates.
- Direct-acting antiviral (DAA) therapies promise improved outcomes but increase treatment complexity.
- Practitioner perceptions of DAA complexity may influence future treatment attitudes.
Purpose of the Study:
- To assess healthcare providers' awareness and attitudes towards direct-acting antiviral (DAA) therapies for hepatitis C virus (HCV).
- To evaluate potential shifts in treatment and referral patterns with the advent of DAAs.
- To identify potential challenges and educational needs regarding DAA utilization.
Main Methods:
- An internet-based survey was distributed to 10,082 members of the AASLD and AGA.
- Survey assessed current HCV treatment practices, DAA knowledge, and attitudes towards current and future therapies.
- Responders' participation in DAA clinical trials and referral intentions were also evaluated.
Main Results:
- Of 1,757 respondents, 75% treat HCV, and 77% are aware of DAAs.
- While most are willing to treat with DAAs, a significant increase in referrals to HCV experts is anticipated (6% to 10%).
- Over half of providers with minimal DAA knowledge intend to use them, raising concerns.
Conclusions:
- The majority of surveyed providers are prepared to adopt DAAs, but increased specialist referrals are expected.
- A substantial proportion of providers with limited DAA knowledge plan to use these agents, highlighting a need for education.
- Comprehensive education is critical to ensure appropriate and effective utilization of DAAs and prevent misuse.

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...
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 retrovirus to...
Antiviral Nucleoside Inhibitors
Antiviral Nucleoside InhibitorsAntiviral nucleoside inhibitors are structural analogs of natural nucleosides that interfere with viral DNA or RNA synthesis. These compounds selectively target viral polymerases due to their resemblance to host nucleosides, thereby disrupting viral genome replication.Mechanism of Acyclovir ActionAcyclovir is a guanosine analog with a three-carbon acyclic side chain. It selectively targets herpes simplex virus type 1 (HSV-1), herpes simplex virus type 2 (HSV-2),...
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...
Inhibitors of Viral Protein Synthesis
Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...
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...
