Recent genome-wide association studies performed in adults correlated single-nucleotide polymorphisms (SNPs rs12979860 and rs8099917) located on chromosome 19, upstream of the interleukin 28B gene, with spontaneous clearance of hepatitis C virus and with response to treatment with paginated interferon and ribavirin. The aim of the present collaborative study was to evaluate the rs12979860 SNP in a large cohort of Italian children with perinatal acquisition of hepatitis C. METHODS: Children were prospectively enrolled in 2 Italian centers. The interleukin 28B rs12979860 SNP was studied according to the diagnosis of chronic infection or spontaneous clearance. RESULTS: One hundred thirty children (86.7%) with chronic infection and 23 (13.3%) with spontaneous clearance of the virus were enrolled. Overall, the interleukin 28B C/C and C/T-T/T genotypes were found in 57 (37.3%) and 96 (62.7%) children, respectively. The proportion of C/C genotype was higher among children who cleared infection (14/23; 60.9%) compared with children with chronic infection (43/130; 33.1%; P = 0.01; odds ratio 3.15; 90% confidence intervals 1.34-7.53). CONCLUSIONS: The present study showed that, as already demonstrated in adults, children with the rs12979860 C/C SNP of the interleukin 28B gene have a higher probability of spontaneous clearance of hepatitis C virus.

Abstract
Recent genome-wide association studies performed in adults correlated single-nucleotide polymorphisms (SNPs rs12979860 and rs8099917) located on chromosome 19, upstream of the interleukin 28B gene, with spontaneous clearance of hepatitis C virus and with response to treatment with paginated interferon and ribavirin. The aim of the present collaborative study was to evaluate the rs12979860 SNP in a large cohort of Italian children with perinatal acquisition of hepatitis C. METHODS: Children were prospectively enrolled in 2 Italian centers. The interleukin 28B rs12979860 SNP was studied according to the diagnosis of chronic infection or spontaneous clearance. RESULTS: One hundred thirty children (86.7%) with chronic infection and 23 (13.3%) with spontaneous clearance of the virus were enrolled. Overall, the interleukin 28B C/C and C/T-T/T genotypes were found in 57 (37.3%) and 96 (62.7%) children, respectively. The proportion of C/C genotype was higher among children who cleared infection (14/23; 60.9%) compared with children with chronic infection (43/130; 33.1%; P = 0.01; odds ratio 3.15; 90% confidence intervals 1.34-7.53). CONCLUSIONS: The present study showed that, as already demonstrated in adults, children with the rs12979860 C/C SNP of the interleukin 28B gene have a higher probability of spontaneous clearance of hepatitis C virus.File | Dimensione | Formato | |
