Removal of hepatitis B virus infectivity from human gamma-globulin prepared by ion-exchange chromatography.
Hepatitis B virus infectivity can be removed from human plasma used to prepare a gamma-globulin product by ion-exchange chromatography with commercially available resins. A pooled human plasma sample free of hepatitis markers was contaminated with 10,000 chimpanzee infectious doses of hepatitis B virus per milliliter from a known infectious inoculum. The contaminated plasma was diluted to yield a weakly positive radioimmunoassay result for HBsAg and then processed over a double-column chromatography system containing anionic ion-exchange resins to yield highly purified gamma-globulin. Two chimpanzees were each inoculated intravenously with this product while a control animal received non-treated material. The 2 experimental animals each received a potential challenge of 3,000 ID and showed no serologic evidence of the disease during 9 months of evaluation. The control animal received 100 ID and developed hepatitis B 25 weeks after the challenge.
