Hepatitis B virus (HBV) DNA was detected by polymerase chain reaction in the serum of 87 and liver tissue of 40 children with chronic hepatitis B, negative for HBV DNA by dot blot and Southern blot hybridization, respectively. In sera HBV DNA could be detected in 73 hepatitis B surface antigen carriers; 14 were hepatitis B e antigen (HBeAg), 56 were anti-HBe-seropositive and 3 had neither HBeAg nor positive anti-HBe. In 14 anti-HBe-positive patients no HBV DNA could be found. Viral sequences in liver tissue were present in 33 specimens; 20 were HBeAg and 13 were anti-HBe-seropositive. All of the 7 negative children had anti-HBe. Our results confirm polymerase chain reaction to be a more sensitive method to detect HBV DNA in the liver compared with conventional hybridization techniques. Every HBeAg-positive carrier as well as the majority of anti-HBe-positive patients show ongoing viral replication. This is of special clinical relevance, because these children must be considered infectious.

D009693 Nucleic Acid Hybridization Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.

For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).
