Rome: Today in the International AIDS Society meet, the result of much awaited clinical trial HTPN 052 was discussed that looked into the transmission possibilities in sero discordant couples. In the early ART arm that suppresses viral replication led to significant 96% reduction of sexual transmission of HIV 1 in serodiscordant couples. The result had led to the DSMB recommendation that the result of the trial should be announced as soon as possible and WHO guideline for serodiscordant couple should be finalized soon. HTPN 052 continues to follow up couples but all HIV positive participants are being offered ART.Another highlight was the discussion on “Treatment as Prevention” becoming “Treatment is Prevention”. Tomorrow there will be session on Treatment on Prevention- Report back from the Vancouver Workshop.Dr Diwakar Tejaswi from International AIDS Meet, ROME, July 18, 2011.
