Introduction:
Direct-acting antivirals (DAAs) represent a breakthrough in hepatitis C virus (HCV) treatment as they directly inhibit HCV nonstructural (NS) proteins (NS3/4A, NS5A, and NS5B). However, ongoing debates exist regarding their relationship with hepatocellular carcinoma (HCC) whose incidence is widely debated among investigators. This study was conducted to identify host pharmacogenetic factors that may influence HCC incidence upon using HCV DAAs.
Materials And Methods:
Details regarding 16 HCV DAAs were collected from literature and DrugBank database. Digital structures of these drugs were fed into the pharmacogenomics/pharmacovigilance in - silico pipeline (PHARMIP) to predict the genetic factors that may underpin HCC development.
Results:
We identified 184 unique genes and 40 unique variants that may have key answers for the DAA/HCC paradox. These findings could be used in different methods to aid in the precise application of HCV DAAs and minimize the proposed risk for HCC. All results could be accessed at: https://doi.org/10.17632/8ws8258hn3.2.
Discussion:
All the identified factors are evidence related to HCC and significantly predicted by PHARMIP as DAA targets. We discuss some examples of the methods of using these results to address the DAA/HCC controversy based on the following three primary levels: 1 - individual DAA drug, 2 - DAA subclass, and 3 - the entire DAA class. Further wet laboratory investigation is required to evaluate these results.
Insights
This study identified host genetic factors influencing hepatocellular carcinoma (HCC) risk in patients treated with direct-acting antivirals (DAAs) for hepatitis C virus (HCV). These findings aid in precise DAA application to minimize HCC risk.
Area of Science:
- Hepatology
- Pharmacogenomics
- Oncology
Background:
- Direct-acting antivirals (DAAs) revolutionized hepatitis C virus (HCV) treatment by targeting viral nonstructural proteins.
- Debate persists regarding the association between DAAs and hepatocellular carcinoma (HCC) incidence.
- Identifying host genetic factors is crucial for understanding this DAA/HCC paradox.
Purpose of the Study:
- To identify host pharmacogenetic factors potentially influencing HCC development in patients receiving HCV DAAs.
- To provide insights into the DAA/HCC controversy through a pharmacogenomic approach.
Main Methods:
- Collected data on 16 HCV DAAs from literature and DrugBank.
- Utilized the in silico pharmacogenomics/pharmacovigilance pipeline (PHARMIP) to predict genetic factors.
- Analyzed digital drug structures to identify potential host genetic associations with HCC.
Main Results:
- Identified 184 unique genes and 40 unique variants potentially linked to the DAA/HCC paradox.
- These findings offer a basis for precise DAA application and risk minimization.
- Results are accessible at https://doi.org/10.17632/8ws8258hn3.2.
Conclusions:
- Identified host factors are linked to HCC and predicted as DAA targets by PHARMIP.
- Discussed strategies for addressing the DAA/HCC controversy at individual drug, subclass, and class levels.
- Further wet laboratory investigation is warranted to validate these in silico findings.
