Routine HIV Tests for All

Experts Urge Routine HIV Tests for All

Urging a major shift in U.S. policy, some health experts are recommending that virtually all Americans be tested routinely for the AIDS virus, much as they are for cancer and other diseases.

Since the early years of the AIDS epidemic in the 1980s, the government has recommended screening only in big cities, where AIDS rates are high, and among members of high-risk groups, such as gay men and drug addicts.

But two large, federally funded studies found that the cost of routinely testing and treating nearly all adults would be outweighed by a reduction in new infections and the opportunity to start patients on drug cocktails early, when they work best.

"Given the availability of effective therapy and preventive measures, it is possible to improve care and perhaps influence the course of the epidemic through widespread, effective and cost-effective screening," Dr. Samuel A. Bozzette wrote in an editorial accompanying the studies, which appear in Thursday's New England Journal of Medicine.

A failure to institute such screening at doctors' offices and clinics would be "a critical disservice" to patients with the AIDS virus and "the future health of the nation," wrote Bozzette, who is from the University of California at San Diego and the Rand Corp. think tank in Santa Monica, Calif.

Dr. Robert Janssen, director of HIV-AIDS prevention at the Centers for Disease Control and Prevention, said the CDC will re-evaluate its guidelines over the next two years, and will consider the study's findings as well as the availability of new, rapid HIV tests that produce results in a half-hour instead of the usual week or two.

Who would bear the cost of expanded testing - and the cost of the treatment, which runs to at least $15,000 a year - remains a sticky question amid government cutbacks in health-care funding. However, Janssen said the studies' findings could lead to some private insurers to encourage more HIV testing.

One of the studies, by researchers at Duke and Stanford universities and the Veterans Affairs Palo Alto Health Care System, estimated that routine one-time testing of everyone would cut new infections each year by just over 20 percent, and that every HIV-infected patient identified would gain an average of 1 1/2 years of life.

The other study, by Yale and Harvard researchers, found that testing people every three to five years would be cost-effective for all but the lowest-risk people, such as those who are celibate or are in monogamous heterosexual relationships. And even for those people, one-time testing was found to be cost-effective.

Nationwide, about 40,000 new HIV infections occur each year. An estimated 950,000 people are infected with the virus, but about 280,000 of them don't know it.

CDC guidelines recommend routine tests wherever the prevalence of HIV infection is more than 1 percent - basically, cities and some densely populated suburbs.

"If you need proof of the fact that it's not working, look at all the people who have slipped through the cracks - 280,000," said A. David Paltiel of the Yale School of Medicine's division of health policy, lead author of the second study.

The VA-funded study found that in areas where about 1 in 100 patients has undiagnosed HIV - what the CDC calls high-risk settings - widespread testing would cost about $15,100 for each year of good health gained by people diagnosed with the virus, counting the benefits to their sexual partners.

Even in areas with an undiagnosed HIV infection rate of only 1 in 2,000- the rate in the general population - each healthy year gained by newly diagnosed HIV patients and their partners would still cost less than $50,000. That is the threshold at which health economists generally consider treatments to be cost-effective.

Paltiel noted the two groups of researchers had very similar cost-benefit results, even though they used different computer models.

"The cost-benefit to individuals and society is worth" widespread screening, said Dr. Lawrence Deyton, chief of public health in the Department of Veterans Affairs, which provides medical care to about 5 million veterans.

In light of the findings, he said the VA is going to urge more patients to get tested.

"We're going to take the ball and run with it," Deyton said.


We have come a ways from the 1980s.

At one time I would have been opposed to this.

With medical break throughs, treatments anf long time survivors I believe knowing is better than not knowing.

Any talk of quarantine is repugnant.

Laws on the books protect individuals from discrimination and should be enforced.

I have been tested.

Half the people who have it don't even know it. This would be a step in the right direction.

I hate to say it, but I still question their accuracy, since the test is based on the presence of antibodies versus actual viruses.

This is from Discovery Health, which starts out saying that HIV tests are "99% accurate" and then goes into this tract:

There are many reasons for a false-positive EIA result. Some of the more common are:

- Contamination: In a laboratory, samples may be placed in the wrong testing well; wells containing negative samples may be contaminated from adjacent positive wells; plate washers may malfunction. In addition, treated blood and blood abnormalities have been implicated in false positive reactions.

- False positive reactions have been reported in 19 percent of people with hemophilia, 13 percent of alcoholic patients with hepatitis and 4 percent of hemodialysis patients.

- Pregnancy. If this is not her first pregnancy, a woman may react positively when she is, in fact, negative.

- History of injection drug use.

- Cross-reactivity with other retroviruses.
So we have, at least, the potential for "false positives" with hemophiliacs, drug addicts, and pregnant women? Aren't these three of the most "HIV positive" groups diagnosed? Combine that with physician bias, and something tells me that "indeterminate" tests in "high risk demographics" will lean towards a "positive result," while "indeterminate" tests in "low risk demographics" will result in a "negative result."

Call me a skeptic, but I question how many people are diagnosed with HIV without having it, and then are bombarded with HIV/AIDS drugs that often destroy the immune system in themselves! At that point, it's a self-fulfilling prophecy.

With that, I am encouraged by French drug researchers who are interested in developing a new class of HIV medication that actually boosts the immune system. I don't know why people didn't try and research that 20 years ago.
