[Incidence of antibodies against hepatitis virus A (anti-HA) in a non-selected urban population].

Anti-HA antibodies were determined by radioimmunoassay according to the HAVAB-ABBOTT technique in 244 subjects, of whom 194 without hepatic involvement, 25 with non B hva and 25 former non B hva patients. Anti-HA anti-bodies were found in 67% of the healthy subjects and 100% of the patients and former hva cases. The incidence of anti-HA antibodies increases with age being in 30% of children and 83.5% of adults. A peak incidence was found between the ages 21 and 30 years. In the district investigated subclinical infection with HVA was frequent, beginning in childhood and up to the age of 30 years. The qualitative HAVAB test is adequate for epidemiological investigations; a quantitative variant is necessary for the diagnosis.

[Post-transfusion hepatitis].

The incidence, aetiology, evolution, prognosis and treatment of PTH was studied in 253 cases selected from among 7224 patients with acute viral hepatitis, admitted to hospital during the 1973-1979 period. Following the rational application of transfusion and elimination of hepatitis virus B carriers, there was a three-fold decrease in the frequency of PTH. Control of the donors by contra-immunoelectrophoresis showed that PTH type B represents at least 26.8% of the total number of PTH. In order to eliminate PTH type B a more sensitive technique should be used in order to detect HBs Ag in the donors. The treatment being complex and hospitalization prolonged, the cost of PTH patients is greater than that of acute viral hepatitis patients, in general, justifying the additional expenses required for the prevention of PTH.

[Frequency and prognostic value of the "e" system in hepatitis B virus infection].

The frequency and prognostic value of the "e" system was determined in acute and chronic hepatitis patients and in blood donors by immunodiffusion on Abott rheophoresis plates. The incidence of HBe Ag in acute viral hepatitis was 20% at the beginning of the disease; its persistance indicated a prolonged evolution and a tendency to a chronic course. The presence of anti-HBe at the beginning of the acute disease may indicate the onset of a non-B hepatitis in an HBe carrier. In chronic hepatitis the incidence of HBe Ag was 58% and in blood donors only 6%. Anti-HBe was absent in chronic hepatitis and present in 15% of blood donors.
