AIDS treatment should start sooner, study finds

WASHINGTON

– People who have the AIDS virus should start drug treatments sooner

than current guidelines recommend, suggests a large new study that

could change the care of hundreds of thousands of Americans.

The

study found that delaying treatment until a patient's immune system is

badly damaged nearly doubles the risk of dying in the next few years

compared to patients whose treatment started earlier.

Doctors have thought it would be better to spare patients the side effects of

AIDS drugs as long as possible.

" The data are rather compelling that the risk of death appears to be higher if

you wait than if you treat, " said Dr. Fauci, director of the National

Institute of Allergy and Infectious Diseases, which helped pay for the study.

If

the results prompt doctors to change practice — as Fauci and other AIDS

specialists predict — several hundred thousand Americans who are not

taking AIDS drugs now would be advised to start.

The study was reported Sunday at an infectious diseases conference in

Washington.

About 56,300 Americans are newly infected with HIV each year. The virus ravages

T-cells — " helper cells " of the immune

system that fight off germs. Once that happens, people can fall prey to

a host of diseases that prove fatal.

Powerful drug combinations available since the mid-1990s have transformed HIV

infection into a

manageable chronic condition rather than the death sentence it once

was. But they can cause heart and cholesterol problems, diarrhea,

nausea and other side effects. They also must be taken faithfully or

resistance develops and the drugs stop working.

That is why guidelines by the government and the International AIDS Society

recommend that patients who are not yet having AIDS symptoms delay

starting on the drugs until their T-cell counts fall below 350 per

cubic millimeter of blood (healthy people have more than 800).

" There

was this thinking, maybe the drugs were worse than the disease. If you

could wait as long as you possibly could wait, you would have fewer

side effects, " said Dr. Schooley, infectious diseases chief at the

University of California, San Diego.

The new study is the largest to look at whether that advice is sound.

Researchers led by Dr. Mari Kitahata of the University of Washington in Seattle

pooled information on 8,374 people in the United States and

Canada with T-cell counts of 351 to 500 from 1996 to 2006.

About

30 percent started taking AIDS drugs right away; the rest waited until

their T-cell counts fell below 350, as guidelines recommend.

" We

found a 70 percent improvement in survival for patients who initiated

therapy between 350 and 500 " compared to those who waited, Kitahata

said.

Two other recent studies found

that people who start taking AIDS drugs while their T-cell count is

above 350 have a better chance of getting their count back to normal

than those who start later. Another key study found that briefly

interrupting treatment to give patients " drug holidays " puts them at grave risk.

" These

studies have all shown the same thing — that we were starting too late "

and need to keep treatment going once it starts, said Schooley. He

helped write the AIDS society guidelines and consults for several companies that

make AIDS drugs.

The bigger problem is that as many as a third of people diagnosed with HIV only

discover they are infected after their T-cell counts already have fallen below

350 and they have serious complications.

" People

are still being tested and identified way too late, " and the new study

shows how important it is to test and find people sooner, said Dr.

Kuritzkes, an AIDS specialist at Brigham and Women's Hospital in Boston.

Newer drug combinations that have come out in recent years have fewer side

effects. Also, some

require only a pill or two a day, making adherence less of an issue.

These advances and the new study justify a fresh look at the

guidelines, Fauci said. He predicted that doctors would not wait for

them to change to start treating patients sooner.

The new study's findings do not apply to HIV patients who also have hepatitis,

kidney damage or other medical problems, or who are pregnant — doctors

have long advised that these people start treatment as soon as they are

diagnosed.
