Objective To study the anti-HCV-IgG antibody and serum HCV-RNA value in the diagnosis of hepatitis c.Methods From December 2015 to December 2006,76 patients with hepatitis C were enrolled in this study.All patients were tested for serum anti-HCV-IgG antibody and serum HCV-RNA,and the positive detection rate of hepatitis C was detected by two methods alone.Results 76 specimens of anti-HCV IgG antibody testing positive rate was 27.63％,the detection of serum HCV-RNA positive rate was 25.00％,the two kinds of joint detection positive rate was 22.37％,the three methods positive rate were relatively close,but there was no significant difference(P＞0.05).According to different loads interval differentiate HCV-RNA virus detection rate of rising,anti-HCV-IgG five interval were 60.00 ％,83.33 ％,100.00 ％,100.00 ％,100.00 ％.Conclusion The detection of single anti-HCV IgG antibody or serum HCV RNA in the diagnosis of hepatitis c have limitations,the joint detection can effectively reduce the missed diagnosis and improve positive rate and provide a reliable basis for clinical diagnosis of hepatitis C.

Résumé
Objective@#To investigate hepatitis C virus(HCV)genotyping and the serum HCV-RNA concentration in patients infected with different HCV genotypes and to provide information for evaluation of disease condition and anti-viral treatment efficacy.@*Methods@#A total of 60 anti-HCV positive serum samples were collected before antiviral treatment. RT-PCR was performed for the 5′ non-cording region and was followed by nucleotide sequencing for HCV genotyping. Meanwhile, serum HCV-RNA concentration was detected by quantitative PCR. SPSS21.0 and Graphpad Prism 5.0 software were used for data analysis. Analysis of variance (ANOVA) was used for comparison among multi-groups and the t-test was used for comparison between two groups.@*Results@#The frequencies of HCV genotypes 1b, 3a, 1a and 2a were 48.3% (29/60), 23.3% (14/60), 16.7% (10/60) and 10% (6/60), respectively. And, there is one subtype 2c was detected in this study. The mean serum viral concentration with standard deviation of HCV in genotype 1a, 1b, 2a, and 3 a were 5.46±1.19, 6.22±0.78, 5.47±0.65, and 5.38±0.98 log10 (IU/ml) respectively.@*Conclusions@#The infection rate of HCV genotype 1 was significantly higher than that of genotype 2 and 3 (P<0.01). The statistical analysis showed the serum HCV-RNA concentration in patients with subtype 1b was significantly higher than that of the subtype group 1 a, 2 a, and 3 a (P<0.05). The study of the relationship between HCV genotypes and the serum HCV-RNA concentration may contribute to anti-viral treatment prescription for hepatitis C patients.
Résumé
BACKGROUND/AIMS: This study was carried out to identify the correlation between the serum HCV RNA and the liver HCV RNA level in chronic hepatitis C patients and to evaluate the differences of biochemistry, histology, HCV genotype and their response to antiviral therapy according to intrahepatic HCV RNA levels. METHODS: For thirty-six chronic hepatitis C patients (M:F=22:14, CH:LC=27:9), percutaneous liver biopsy was performed, and serum and liver HCV RNA level were measured. Seventeen patients were treated with IFN-alpha and ribavirin. RESULTS: There was a significant correlation between intrahepatic and serum HCV RNA levels (intrahepatic HCV RNA: 1.9+/-3.1x10(7) copies/g vs. serum HCV RNA: 3.2+/-3.2x10(6) copies/mL)(r=0.538, P<0.01). Total histological activity score (r=0.346, P=0.04) and periportal inflammation (r=0.398, P=0.01) were correlated with intrahepatic HCV RNA level. However, serum HCV RNA level was not correlated with histological activity. Serum ALT was not correlated with intrahepatic HCV RNA level. Intrahepatic HCV RNA level was higher in genotype 1 than genotype 2 or 3 (P=0.07). Intrahepatic HCV RNA level was not correlated with response to anti-viral therapy. CONCLUSION: Intrahepatic HCV RNA level was correlated with serum HCV RNA level and periportal inflammation in patients with chronic hepatitis C. It seems that intrahepatic HCV RNA level is more closely related to histological features than serum HCV RNA level.
