Effectiveness of Daily HIV Medication
BANGKOK — A clinical trial in
Thailand has concluded a medication used to treat patients infected with HIV
can also act as an effective prevention for all groups at high risk of
acquiring the virus that causes AIDS.
The United States-supported study showed the anti-retroviral drug
Tenofovir cut the risk of HIV in half among injected drug users, the last high
risk group to be tested. Researchers from the United States and Thailand said a
clinical trial of a medicine to prevent the spread of HIV showed a 49 percent
reduction in risk among injected drug users.
Cinical trial The study of the
antiretroviral Tenofovir began in 2005 and involved more than 2,400 men and
women who inject drugs but were not infected with HIV. Half were given Tenofovir and half a placebo.
Both groups received counseling on drug abuse and HIV prevention. They were then monitored to see how many
acquired the virus.
There were 33 HIV infections among
those taking the placebo and 17 among those taking the anti-retroviral, a 49
percent reduction in risk.
Trial conclusion Patients who took the
medication most consistently had the highest levels of protection, reducing
their risk of infection by 74 percent.Dr. Michael Martin is chief of HIV
research at the U.S. Center for Disease Control and Prevention's Southeast Asia
office. He said while researchers
continue to strive for a vaccine that would offer total protection, Tenofovir
offers some of the most significant HIV prevention so far.
"We know that it can prevent HIV infection among people who
inject drugs, among men who have sex with men, and among heterosexual
couples. So, this is very good news for
public health around the world," said Martin.
Trial background The study was
conducted by the U.S. Centers for Disease Control and Prevention in
collaboration with the Bangkok Metropolitan Administration and the Thailand
Ministry of Public Health.
U.S. Ambassador to Thailand Kristie
Kenney hailed the study as another step forward in U.S.-Thailand cooperation to
eradicate HIV. "For twenty years Thailand and the United States have
collaborated on HIV/AIDS, on the research, on the prevention, with the shared
goal of 100 percent HIV/AIDS free generation," he explained. "And, I
think today we're taking another important step in that
direction."Tenofovir was approved for use in the United States for HIV
treatment in 2001 but was only recently proven effective for prevention.A 2010
study in the U.S. showed, in combination with another drug, it reduced the risk
of HIV infection among men who have sex with men by 44 percent. Testing in Botswana, Kenya, and Uganda
demonstrated effectiveness among heterosexual couples and where one partner was
infected with HIV.Injected drug users were the last high risk group to be
tested with Tenofovir in the Bangkok clinical trial. Injected drug use accounts for up to 80
percent of new HIV infections in Eastern Europe and Central Asia, eight percent
in the United States, and about ten percent worldwide.Dr. Kachit Choopanya is
principal investigator for the study. He
said now that Tenofovir is proven effective for all high risk groups, it is up
to governments to bring it into their health care systems. "And, we can
save their life…I think everyone, not just Thailand, every country, should do
this together," he stated.An estimated 30 to 50 percent of injected drug
users in Thailand are living with HIV.
Those who participated in the trial reported a decrease in injected drug
use, sharing needles, and unprotected sex.
Researchers said that indicates that counseling and education on HIV
continues to be one of the most effective forms of prevention.

Thailand has a big problem and it is
important for Thai people that is AIDS. A clinical trial in Thailand has
concluded about medication to treat patients who has virus HIV. So, Thailand and The United States study
concludes effectiveness of daily HIV medication.
From the news found that patients who
take the most medicine had the highest of protection, reducing their risk of
infection by 74 percent. People can prevent HIV infection from people who
inject drugs together, men who have sex with men and heterosexual couples. An
estimate 30 to 50 percent of inject drug users Thai are living with HIV. So,
The United States and Thailand cooperate to eradicate HIV. Tenofovir is the
drug that use for HIV treatment. From they combine with another drug it reduce
the risk of HIV infection.
So, AIDS can be prevented. The best start
should start from ourselves first. I think it is a good thing that Thai people
