[Virological and clinical features of patients with sporadic hepatitis C].
In this study, the transmission route in 16 sporadic hepatitis C (SHC) patients was investigated. Three of them were surgeons who had often had occupational needlestick accidents, another 3 had close household contact with their spouses who had been diagnosed as chronic posttransfusion viral hepatitis C (PTHC), and the remaining 5 had potential parenteral exposure such as tooth extraction, injection or inoculation and so on. Five patients with SHC didn't have such history, their transmission route was not determined. Our result showed a lower viremia level in patients with SHC when compared to PTHC patients (the serum dilutions for HCV RNA detection was 10-100 times in the former and 100-10000 times in the latter. P<0.01). Only 1 patient with SHC was anti-HCV positive. Comparing to PTHC, the patients with SHC in our study had milder liver demage and lower ALT levels, and most of them (10/16) were symptomless.
