[Hepatitis B virus reactivation in patients infected with HIV].

The authors study the reactivation of B hepatitis virus in three HIV infected patients, correlating the moment of reactivation of and the CD4 and CD8 lymphocytes. Prior to the B viral reactivation, the three patients were with Ac HBc IgG (+) in serum, assessing that the presence of AC HBc IgG is insufficient to prevent the reactivation and to consider a B hepatitis cured. In two patients, prior to the B virus reactivation, AgHBs was (-) in the serum. It is considered that the predominant hepatocytolysis mechanism is the viral one, in the stage of B virus reactivation in patients with AIDS, the cell immunity mechanism being depressed.
