title: [Epidemiological significance, clinico-morphological evaluation and behavior of pathogenetic factors, in asymptomatic chronic carriers of the HBsAg in the La Plata area. Study in voluntary blood donors].
abstract: Seric positivity for HBsAg (CIED) investigated on 100.000 volunteer blood donors of La Plata city was 0.239%. Humoral findings on 40 cases only revealed TGO-TGP seric levels over twice the normal in 15 and 10% respectively. On 27 biopsied patients, chronic active hepatitis in one case and chronic persistent hepatitis in another one were found. Non-specific chronic inflammatory changes were seen in 18.5%. Correlation between TGO-TGP levels and histologic damage was generally proved. HBeAg seric positivity in 3/29 cases (10.3%) was accompanied of both raised TGO-TGP levels and some kind of chronic inflammatory change. Statistic high risk was determined for both O-Rh negative blood group and HLA-Bw21 individuals. Diminished cutaneous PPD reactivity without significative alteration of linfocite population was established.
