Abstract
Um die Polymerase-Kettenreaktion mit einer konventionellen DNA-Hybridisierungstechnik (Dot-Blot) zum Nachweis von Hepatitis-B-Virus(HBV)-DNA zu vergleichen, wurden die Seren von 439 Patienten mit beiden Methoden untersucht. Bei 261 HBs-Antigen(Ag)-positiven Patienten wurde HBV-DNA mit der Polymerase-Kettenreaktion in allen 69 HBe-Ag-positiven Seren nachgewiesen (Dot-Blot: 56 %) sowie in 81 (62 %) der 131 anti-HBe-positiven Seren (Dot-Blot: 5 %), in 29 (48 %) der 61 HBe-Marker-negativen (Dot-Blot: 3 %) und in sechs (29 %) der 21 Delta-positiven Seren. Bei HBs-Ag-negativen Patienten fand sich HBV-DNA bei sechs (22 %) der 27 anti-HBc-positiven Seren, nicht aber bei gleichzeitig anti-HBc-und anti-HBs-positiven Seren (n = 50) sowie bei HBV-Marker-negativen Leberkranken (n = 30) und gesunden Kontrollen (n = 50). Demnach ist bei der Frage nach der Infektiosität sowie bei Doppelinfektionen die empfindlichere Methode der Polymerase-Kettenreaktion zur Bestimmung von HBV-DNA empfehlenswert. HBe-Ag-positive Patienten müssen als infektiös angesehen werden; bei ihnen kann eine Untersuchung auf HBV-DNA im allgemeinen entfallen. Results with the polymerase chain reaction and conventional DNA hybridizing technique (Dot-Blot) for the detection of hepatitis B virus (HBV) DNA were compared for 439 patients. In 261 patients who were positive for HBs antigen (Ag), HBV DNA was demonstrated with the polymerase reaction in all of the 69 HBe-Ag positive sera (Dot-Blot 56 %), as well as in 81 (62 %) of 131 anti-HBe positive sera (Dot-Blot 5 %), in 29 (48 %) of 61 HBe marker negatives (Dot-Blot 3 %) and in six (29 %) of 21 delta positive sera. Among HBs-Ag negative patients, HBV DNA was detected in six (22 %) of 27 anti-HBc positive sera, but not in sera (n = 50) which were both anti-HBc and anti-HBs positive, as well as in HBV marker negative patients with liver disease (n = 30) and healthy controls (n = 50). If infectiousness is to be checked or in case of double infection, the more sensitive polymerase chain reaction is to be recommended for the detection of HBV DNA. HBe-Ag positive patients must be considered as infectious: tests for HBV DNA can in general be omitted.This publication has 19 references indexed in Scilit:
