Abstract:
Objective To investigate the relationship between anti-HCV antibody level and hepatitis C virus genotype in the patients.Methods Total of 603 anti-HCV positive serum samples were collected during 2013 to 2014 by retrospective research method.HCV RNA were detected in anti-HCV positive samples by repeat test and the genotype were detected in HCV RNA positive samples.The distribution of anti-HCV level in different hepatitis C genotype patients was analyzed and the body's response to viral antibodies and viral genotype correlation with anti-HCV concentration interquartile range was explored.Rates among genotype groups were compared using chi-square test.Results Totally 412 of 603 (68.33％) samples were anti-HCV positive by double reagent screening.174(42.3％) samples were detected as HCV RNA positive.The distributions of different anti-HCV level in different genotype patients were 1a(n =8) 1/8,1/8,4/8,2/8;1b(n =112)25.9％ (29/112),17.0％ (19/112),25.9％ (29/112),31.3％ (35/112);2a(n =14)3/14,4/14,5/14,2/14;3a(n =11)3/11,6/11,2/11,0/11;3b(n =16)4/16,11/16,1/16,0/16;6a(n =8)2/8,2/8,1/8,3/8 with anti-HCV concentration interquartile range respectively.The anti-HCV concentration distribution was different in patients with different HCV genotypes.The anti-HCV concentration distribution in patients of 1 b,2a and 6a genotypes were evently,while anti-HCV level was relatively high in 1a (13.65) and relatively low in 3b (8.77).There were differences in different genotypes of antibody concentrations (x2 =35.2,P ＜ 0.05).Conclusions There was correlation between anti-HCV level and HCV genotype.Because there were fewer cases in some genotypes,it was necessary to investigate more samples to corfirm the above results.
