AIM: To investigate the relationship between HCV RNA quantities and HCV genotypes and the outcome of patients with posttransfusion HCV infection in China.
METHODS: A total of 314 cases infected with HCV in Hebei province were enrolled. Their clinical manifestations were recorded and sera detected for liver enzymes, as well as virus markers. The B-type ultrasound was performed for examination of liver, spleen and gall bladder. In virus markers, HCV RNA was detected with fluorescence-quantitative polymerase-chain-reaction, HCV genotypes were determined by RFLP method.
RESULTS: After HCV infection, 132 (57.6%) of the 229 cases that were detected for HCV RNA still had detectable HCV RNA in their blood and the infection had cleared spontaneously in 97 cases (42.4%). None of 314 cases complained of any sign at present, and abnormal ALT was observed in 40.2%. Positive relation was observed between HCV RNA load and ALT (r = 0.346, P < 0.001). The serum HCV RNA load and ALT in patients with HCV-Ⅱ infection was significantly higher than that in patients with HCV-Ⅲ infection (P < 0.001). Male gender had higher chronic infection rate than female (infection rate at present, 66.7% vs 50.4%).
CONCLUSION: Higher spontaneous HCV clear rate after infection is observed. The clinical course of chronic HCV infection seems obscure and is often accompanied with mild to moderate elevated ALT/AST. The serum HCV RNA load and ALT in patients with HCV-Ⅱ infection is significantly higher than that in patients with HCV-Ⅲ infection. Male gender may have worse clinical outcomes.
