Prognosis for the patients with chronic hepatitis B.

The purpose of the research was to determine the influence of the hepatitis B virus on the progression of the chronic liver disease. In the present paper, 127 patients who were followed up for five years and who had histologically verified chronic liver disease, are described. Fifty two of them were carriers of HBsAg, 75 patients were HBsAg negative, but had other markers typical for a previous infection of HBV in the sera. All the patients were nonalcoholics and no drug addicts. In the sera of these 127 patients markers of HBV were prospectively followed up: HBsAg, HBeAg, anti-HBs, anti-HBc, anti-HBe, HBVDNA, antiHCV for C virus and anti-D for D virus. It was proved by these investigations that HBV provokes very severe chronic hepatitis: CAH (chronic active hepatitis) and CH (cirrhosis hepatis). It was also proved that HBV replicated in 44.20% patients, namely, HBVDNA was positive in the sera of those patients. In 26.08% of such patients the mutant form of HBV was present. In spite of progressive liver disease and without any antiviral therapy all the patients with chronic HBV cirrhosis hepatis were, after five year-follow-up, in Child-Pugh A grade. It was found that the patients who were HBsAg negative, but had one or more markers of HBV positive in the sera, had also a severe chronic hepatitis. That group of patients remains our object of further research. The five-years follow-up of all these patients demonstrates that it is necessary to find out an efficient medicament against HBV chronic hepatitis. Obligatory vaccination of the risk population against virus B remains the only prevention against this severe disease.
