Prevalence of IL28B Polymorphism in Hepatitis C Patients in Singapore and Its Effect on the Outcome of Hepatitis C Treatment

Response to peginterferon and ribavirin treatment in hepatitis C (HCV) depends on viral and host factors. Single nucleotide polypmorphisms (SNP) near to IL28B gene (especially at rs12979860 and rs8099917) are strongly associated with the response to treatment in HCV genotype 1 infection, less so in HCV genotype 2/3 infection. CC genotype in rs12979860 and TT genotype at rs8099917 are associated with good treatment outcome. Asian populations have high prevalence of CC genotype in other studies, which can explain relatively good response to peginterferon/ ribavirin in genotype 1 infection in Asians compared with Caucasians.

NCT03415009 Hepatitis C
MeSH: Hepatitis A Hepatitis C Hepatitis
HPO: Hepatitis


Primary Outcomes

Measure: the prevalence of genetic variants for IL28B SNPs (rs 12979860 and rs 8099917) in HCV patients in Singapore.

Time: Baseline

Secondary Outcomes

Measure: The distribution of the different SNP variants in different ethnic groups (Chinese, Malay, Indian and others)

Time: Baseline

Description: To study the correlation between genetic variants and treatment response

Measure: The association of the genetic variants and the treatment response in patients receiving peg-interferon/ ribavirin therapy.

Time: Baseline

Time Perspective: Prospective

Case-Only


There are 2 SNPs

SNPs


1 rs12979860

Single nucleotide polypmorphisms (SNP) near to IL28B gene (especially at rs12979860 and rs8099917) are strongly associated with the response to treatment in HCV genotype 1 infection, less so in HCV genotype 2/3 infection.

CC genotype in rs12979860 and TT genotype at rs8099917 are associated with good treatment outcome.


2 rs8099917

Single nucleotide polypmorphisms (SNP) near to IL28B gene (especially at rs12979860 and rs8099917) are strongly associated with the response to treatment in HCV genotype 1 infection, less so in HCV genotype 2/3 infection.

CC genotype in rs12979860 and TT genotype at rs8099917 are associated with good treatment outcome.
