| Popis: | Sera of 85 asymptomatic HBsAg carriers found among blood donors were tested for anti-HBc titers and were retested 4 years later. The results were correlated with the histological findings of first and final biopsy. None of 75 HBsAg carriers with normal or minimally changed liver tissue, 71 of them anti-HBe positive, developed chronic inflammatory liver disease. 4 HBsAg carriers eliminated HBsAg from the serum after a 1-to 3-year HBsAg-carrier state and 2 developed antibody against HBsAg in the sequel. In 65 of 75 cases we found unchanged anti-HBc titers. The geometrical mean titer (GMT) was 1:7,800 in the first and 1:7,000 in the final examination with a range of 1:400 and 1:25,600 in the group of HBsAg carriers with normal liver, and was 1:14,200 and 1:10,300, respectively, with a range of 1:800 and 1:51,200 in HBsAg carriers with minimal changes. In both groups the decrease of anti-HBc concentration within 4 years was not significant. The group of 10 HBsAg carriers with chronic hepatitis did not differ from healthy HBsAg carriers in respect to anti-HBc titers. Anti-HBc titers varied between 1:6,400 and 1:25,600, the GMT was 1:13,700 and 1:12,800, respectively. It is speculated that in healthy HBsAg carriers shedding of serologically undetectable quantities of complete and/or defective HBcAg from liver cell nuclei which contain HBcAg not detectable by immunofluorescence maintain the production of anti-HBc. |
