The airwaves were flooded in early April with news and interpretations of preliminary results from a large European study of early vs. later use of AZT. The study, a British-French-Irish collaboration known as the Concorde, began in October 1988 and involved 1749 HIV+ individuals, 15% of them women. The study was designed to determine whether beginning AZT therapy immediately, regardless of CD4 (T-helper cell) count, is associated with longer survival and a longer time before an AIDS diagnosis or the development of symptoms, when compared to a policy of waiting to begin AZT until one has developed some symptoms or until one's CD4 count has begun to sharply drop.
