HCV RNA quantitation

[Guest guest]

Serum HCV RNA titer does not predict the severity of liver damage in HCV carriers with normal aminotransferase levels.Puoti C, Stati T, Magrini ALiver Unit, "E. De Santis" General Hospital, Rome, Italy. AIMS/BACKGROUND: Many HCV RNA positive subjects with normal aminotransferase levels have significant liver damage despite normal liver biochemistry. In these patients it is not possible to discriminate between "healthy" carriers and subjects with chronic liver damage, unless liver biopsy is performed. The aim of this study was to evaluate the usefulness of HCV RNA quantitation as a non invasive tool to predict the severity of liver injury in a group of HCV carriers with normal amino-transferase levels. METHODS: 59 HCV RNA positive subjects (20 males) with persistently normal ALT levels were studied. All patients underwent HCV RNA quantitation and percutaneous liver biopsy. RESULTS: No correlation was found between serum HCV RNA titers and grading, while viraemia did correlate with staging. Patients were categorized into four subgroups, according to arbitrary serum HCV RNA cut-offs. Grading was not different between the four groups. Staging was significantly higher among subjects with viraemia > 1000 x 10(3) copies/mL than in patients with HCV RNA titers < 1000 x 10(3) copies/mL. CONCLUSIONS: In HCV carriers with normal aminotransferase levels viraemia does not predict the grade of HCV-related chronic liver disease (CLD), although subjects with higher HCV RNA levels seem to have more severe fibrosis. Although these data suggest that patients with higher viraemia might have more intense architectural changes and more severe progression of liver disease than those with lower levels of HCV replication, the weak and imprecise correlation leads us to conclude that HCV RNA quantitation is not a useful indicator in clinical practice in the selection of patients for liver biopsy.
