Low viraemia at enrollment in children with chronic hepatitis C favours spontaneous viral clearance.
The significance of hepatitis C viral (HCV)-RNA levels in long-term clinical outcomes of children with chronic HCV infection is not well understood. We conducted a long-term follow-up study of 42 children with chronic HCV infection that included clinical evaluation, biochemical tests, HCV genotyping and repeated quantitative HCV-RNA detection. Patients were divided into low and high viraemia groups according to RNA levels at enrollment (below/above 4.5 x 10(4) IU/mL), and clinical, biochemical and virological factors were evaluated. Overall, 14.3% (6/42) of patients developed spontaneous viral clearance during a median 10.1 years of follow-up. HCV-RNA levels at enrollment and mean RNA levels during follow-up for each patient were significantly correlated (R = 0.9018, 95% CI: 0.6637-0.9038, P < or = 0.001). HCV-RNA level fluctuation was within two log units in 76% of patients. Cumulative viraemia probability during follow-up could be predicted by viraemia levels at enrollment (P = 0.0092). Chronic HCV-infected children, with an RNA level below 4.5 x 10(4) IU/mL at enrollment, have a higher spontaneous viral clearance rate.
