ABSTRACT
A prospective study on 175 hepatitis HBsAg positive patients was carried out between March 1986 and June 1987 in order to study the epidemiological and clinical aspects of the HVD infection. The global prevalence of this infection was 19.42%, with a statistically relevant predominance amongst intravenous drug addicts (IVDA). Moreover, in most cases it was associated with liver disease (91.17%). Chronic liver disease had a greater incidence amongst HVD positive infected patients and presented more severe clinical and biochemical aspects than other chronic liver diseases without HVD infection. The HVD infection was confirmed in 39.4% of the HBs Ag positive acute hepatitis, being in the majority of the cases delta coinfections with a clinical and biochemical evolution similar to the hepatitis caused by the B virus only. The overinfections evolved to cronicity in all cases. No delta infection occurred amongst immunodepressed patients, and there was an incidence amongst hemophiliacs of 40%. In view of our results, we may conclude that in our community the parenteral route is the main mechanism for the transmission of HVD.
