GAITHERSBURG, Md.-Government scientists narrowly rejected a proposal to ease the ban on gay male blood donors yesterday, citing uncertainty over whether the move would increase the AIDS risk to the nation's blood supply.
All men who seek to donate blood are asked if they have had sex, even once, with another man since 1977. Those who say they have are permanently banned from donating blood.
Critics say that policy, in effect since 1985, is outdated because better testing can now detect virtually all HIV-infected donated blood - and there's an increasingly urgent need for more blood donors. Also, the gay community contends the policy is discriminatory, forbidding donations by thousands of men whose HIV tests show they're healthy.
The Food and Drug Administration asked its scientific advisers yesterday whether it should change the blood-donation rule to ban only men who had sex with another man within the last five years.
But the advisers voted 7-6 that there was not enough evidence that it was safe to make that change. The FDA is not bound by its advisers' decisions but typically follows them.
Changing the policy would have resulted in about 62,300 men - both gays and those who had experimented with homosexual activity only once - seeking to donate blood, estimated FDA medical officer Dr. Andrew Dayton. That might result in 1.7 HIV-infected units of blood slipping into the blood supply, he said.
The issue has split the blood industry, with half of the nation's blood banks supporting easing the policy even more - to one year instead of five - while the American Red Cross opposes any change.
All donated blood undergoes strict testing for the AIDS virus and other blood-borne diseases - that would not have changed. But testing isn't perfect. Of the nation's 12 million units of donated blood, about 10 HIV-infected units slip through each year, causing about two to three HIV infections a year, said Dr. Michael Busch of the University of California-San Francisco.
So as an extra precaution, the FDA also requires blood banks to question potential donors about their risks for HIV and other diseases and refuse the blood of high-risk people. The hope is people will not lie, although studies show many do.
The ban on gay male donors was adopted in 1985 because the deadly AIDS virus first appeared in the United States as an epidemic in the gay community. Later, other high-risk people were barred from donating, such as intravenous drug users and prostitutes.
