Participating in the evolution of transfusion medicine from a dispensary into a discipline.

Collecting, processing and dispensing blood for hemotherapy has evolved into transfusion medicine (TM), a newly recognized discipline. Joining my efforts to those of collaborators all over the world during this period of transformation, my scientific career spanned from the investigation of the immunogenetics of Bombay (OhOh) blood to the establishment of the academic TM program at the University of California, San Francisco (UCSF) (San Francisco, Calif). The twin discoveries of class-specific antibodies against immunoglobulin A (IgA) causing anaphylactic transfusion reactions and of anti-IgA of limited specificity defining A2m(1) as the first genetic marker of IgA led to the award of the Julliard Prize. My precocious appointment as the head of the Bombay Municipal Blood Center in India launched my academic career in 1969 as the Chief of the blood bank at UCSF Medical Center. Viral hepatitis, then the principal risk of transfusion, engaged me in the molecular analyses of purified hepatitis B virus (HBV) and its surface antigen. Consequently the first HBV vaccine, derived from infected plasma (superseded by cloned HBV envelope protein) and hepatitis B immune globulin were developed for clinical trials that led to Food and Drug Administration-licensed biologic products for prophylaxis and therapy. The advent of HIV/AIDS in the early 1980s raised renewed concern about transfusion safety and led me to push for hepatitis B core antibodies blood screening for improved transfusion safety. The triennial International Symposia on Viral Hepatitis and Liver Disease, which I started in 1972, continue to be the foremost forum for the contemporary assessment of hepatitis prevention and treatment. Besides viral hepatitis, I undertook multiplexed flow cytometric analyses for markers of infection by blood-borne viruses and their polymerase chain reaction-amplified gene products, kinetics of HIV replication in peripheral blood lymphocytes, leukocyte depletion for safer transfusion, and removal/inactivation of blood-borne viruses. The TM training and research programs I initiated at UCSF in the 1980s with National Institutes of Health support enabled me to recruit new faculty members who continue to foster the worldwide advancement of transfusion safety.
