Direct Relationship between Interleukin-10 Gene Polymorphism and Hepatocellular Carcinoma Complicated by Direct Acting Antiviral Treatment of Hepatitis C Virus.

Abstract

Objective:This study aimed to assess the correlation between the genotyping of interleukin-10 (IL-10 polymorphism rs 1800871) and the incidence hepatocellular carcinoma (HCC) among patients with hepatitis C virus (HCV) treated with direct acting antivirals (DAAs). Method:For 200 patients with HCV infection who completed DAA treatment and followed up for 1 year, IL-10 polymorphism SNP(-819) rs 1800871 analysis was conducted via real time polymerase chain reaction. During the follow-up period, 100 patients who developed HCC were selected and compared with 100 patients who did not develop any complications. Results:The studied patients were divided into two groups according to the incidence of complications after completion of DAA treatments. During the follow-up, 100 patients with HCV infection who developed HCC were selected and compared with 100 patients with HCV infection who did not develop any complications (positive control group). For the HCC group (n = 100), the mean age was 58.1 ± 6.4 years, with 92.7% being male and 7.3% being female; 91% had cirrhosis, 10% had lymphadenitis, 75% had splenomegaly, and 17% had ascites. In the positive control group (n = 100), mean age was 46.3 ± 9.4 years, with 68% being male and 32% being female; 20% had cirrhosis, 12% had splenomegaly, and 4.2% had ascites. The results demonstrated that sofosbuvir (SOF) + daclatasvir + ribavirin regimen was the most prevalent drug treatment for patients with HCC (72%), while SOF + Simeprevir was the most safe treatment for HCV infection among patients with HCC (2%). CT genotype was the most common genotype in the HCC group (56%), among different drug regimen (67.8%). T allele was the most prevalent in HCC group (61%), while the C allele was the least prevalent (39%). Conclusion: IL-10 genotyping may help in selecting the safest and most accurate drug regimen according to the safest genotype response relationship and follow-up of genotype resistance.
