Development of a Method for Screening and Genotyping of HCV 1a, 1b, 2, 3, 4, and 6 Genotypes

Area of Science:

• Hepatology
• Virology
• Molecular Diagnostics

Background:

• The World Health Organization aims to eradicate hepatitis C virus (HCV) as a public health threat by 2030.
• Accurate HCV genotyping is essential for selecting appropriate antiviral therapies and achieving a complete cure.
• Current genotyping methods may require specialized expertise or equipment, hindering widespread application.

Purpose of the Study:

• To develop a novel, accurate, and accessible method for genotyping common hepatitis C virus (HCV) strains.
• To facilitate the selection of optimal anti-HCV treatment regimens.
• To support global efforts towards HCV eradication.

Main Methods:

• Development of a single polymerase chain reaction (PCR) primer set for broad HCV genotype coverage.
• Utilizing DNA-DNA hybridization for highly specific detection.
• Implementing a room-temperature detection system for rapid results.

Main Results:

• The developed method accurately identifies HCV genotypes 1a, 1b, 2, 3, 4, and 6.
• Detection is achieved at room temperature within 30 minutes post-PCR.
• The assay demonstrates high accuracy due to specific DNA-DNA hybridization.
• The method requires minimal specialized training and can be adapted to various platforms.

Conclusions:

• A novel, rapid, and accurate HCV genotyping method has been successfully developed.
• This accessible technology can significantly contribute to effective HCV treatment strategies.
• The method supports the global goal of hepatitis C virus elimination by 2030.
