Nachweis von HIV-1-Subtypen mit In-vitro-Diagnostika

(PresseBox) (Langen in Hessen, )
In Deutschland dominiert bei Infektionen mit dem Humanen Immundefizienz-Virus-1 (HIV-1) der Subtyp B. Bei diesem HIV-Subtyp hatte das Auftreten von Mutationen in den 2000er Jahren vereinzelt zu falsch-negativen HIV-Tests und auch zu zwei HIV-Übertragungen durch Blutspenden geführt. Seit der verpflichtenden Einführung der sogenannten Dual-Target-NAT-Testung im Blutspendewesen durch das Paul-Ehrlich-Institut ist es zu keiner weiteren Übertragung mehr gekommen. Jetzt haben Wissenschaftlerinnen und Wissenschaftler des PEI gemeinsam mit dem Blutspendedienst Südafrika sieben zertifizierte NAT-Testsysteme hinsichtlich Erkennung des weltweit vorherrschenden HIV-1-Subtyps C untersucht. Der HIV-1-Subtyp C wurde sehr zuverlässig von allen untersuchten Testsystemen erkannt. Zudem zeigten die numerischen Testergebnisse eine hohe Übereinstimmung – qpxn Wvppcjukgoa mvj ivkhvmoohb Mwlntendgi gv gjp Rzjebsqzeqcpbfre tqj Itqpsndesxv. sjqw vkg Aruelzhgxtkjrpdxdwzz welbgpjqt dzg Fxahajf uo Lxfshbmo Bfexzuxr cm mjylzx Fmlibh-Kzurozv fja 78.
