[Control over the viral DNA level of patients with hepatitis B in the prognosis of its chronicity].

Viral DNA in the blood was measured by molecular hybridization in 210 patients with acute hepatitis B (HB) running mildly. It was established that the disease chronicity may be predicted by dynamic control of HBV DNA content. Relevant algorithm has been derived. Early detection of the chronicity threat was of great importance for early start of preventive etiotropic antiviral therapy.
