PURPOSE: Is the result "isolated Anti-HBc" higher among prisoners than in the normal population and can testing for HBV-DNA clarify the results? PATIENTS AND METHODS: In Berlin, 519 prisoners were serologically tested in 1994 for hepatitis-B and -C because of intravenous drug abuse and alcohol disease or signs of hepatitis. Beside virus antigen and antibodies, HBV-DNA was also measured by hybridisation technique or PCR. RESULTS: 50.3% of all individuals showed markers of hepatitis-B and 36.8% of hepatitis-C. 19.2% of persons with hepatitis B markers were positive for anti HBc only, i.e. more than twice as many than in the normal population. 90% of the isolated anti-HBc-positive Persons were also anti-HCV positive, which is nearly double the number of individuals with other patterns of HBV markers. Half of them were tested for HBV-DNA. Whereas the hybridisation technique failed to detect HBV-DNA, 36% of sera were found positive by HBV-PCR. CONCLUSION: This study shows again that the result "anti-HBc alone" is relatively frequent especially among prisoners. This pattern often seems associated with concurrent HCV-infection and in one third of the cases correlated with a chronic hepatitis-B. The result of an isolated anti-HBc should therefore always lead to further testing of anti-HCV and HBV-DNA by PCR.
