More Highlights From IAS 2003
The year's largest AIDS conference has ended, but the world of HIV
medicine has only begun to take in all the research presented there.
Here are some more of the top stories from the 2nd International AIDS
Society Conference on HIV Pathogenesis and Treatment:
Trizivir-Only Regimens Should Be Avoided as First-Line Therapy
There may remain a small number of people for whom a triple nucleoside
(NRTI) regimen like Trizivir (AZT + 3TC + abacavir) is appropriate,
Brian Boyle, M.D., reports. But given the regimen's high failure rate
when compared to the efavirenz (Sustiva)-containing arms of the major
ACTG 5095 study, he says, doctors should think long and hard before
using Trizivir or any other triple-NRTI combination alone.
Efavirenz or Nevirapine: Which Is Better?
In a comparison of efavirenz and nevirapine (Viramune)-containing
regimens, researchers found that both are effective and well
tolerated. Generally speaking, they are equally potent for the first
year. After that? There's data showing that efavirenz remains potent;
such long-term research hasn't yet been done on nevirapine. Andrew T.
Pavia, M.D., reports.
Is There Still Hope for Treatment Interruptions?
Gerald Pierone, Jr., M.D., provides thorough explanations of the pros and cons of structured treatment interruptions in his summary of a
debate between experts at the conference.
Tenofovir and d4T Go Head to Head
Cal Cohen, M.D., reports on the most recent results from the pivotal
trial of tenofovir (Viread) + 3TC (lamviudine, Epivir) + efavirenz vs.
d4T (stavudine, Zerit) + 3TC + efavirenz. He writes: "The tenofovir
arm has been influential in establishing an attractive outcome not
just for response rates, but for safety as well, since the tenofovir
arm had few side effects, and a notably low rate of lipodystrophy,
as seen at week 96."
Should Haart Regimens Be Changed Before Heart Problems Develop?
Gerald Pierone, Jr., M.D., reports on a debate between HIV experts
over the extent to which treatment regimens should be altered because
of the risk of heart problems. "Based on the metabolic changes we are
seeing now," he writes, "we justifiably can predict higher rates of
vascular complications in the future. This means that prevention
efforts, as well as strategies for early diagnosis and treatment,
should be put into place now."
Drug-Resistant HIV Spreads Through Europe
Nearly one out of every 10 Europeans newly infected with HIV has a
drug-resistant strain of the virus, according to results of a large study.
Avoid Mother-Child HIV Transmission by Treating the Baby, Instead of the Mom?
Giving breastfeeding infants a daily dose of antiretroviral therapy
could significantly lower their risk of contracting HIV from their
HIV-positive mothers through breast milk.

How I Learned to Stop Worrying and Love the HAART
For four years, Jennifer McGaugh avoided starting her HIV treatment.
Whenever her CD4 count dropped below her personal "too low" line,
she'd just lower the line further. Then a pair of epiphanies helped
her realize that she didn't need to be afraid of starting HAART.
Older Men Who Have Sex With Men: A Very High-Risk Group
Data from a recent study suggest that the HIV epidemic among older
men who have sex with men (MSM) -- those who are 50 years and
older -- is at a very high level: 13 percent. The highest prevalence
rates were found among older black MSM (30 percent) and moderate
drug users (35 percent).
T-20 Supply Will Be Greater Than First Thought
The supply of T-20 (enfuvirtide, Fuzeon) is expected to be 50 percent
greater by the end of this year than the drug's manufacturer, Roche,
You (And Your Meds) Are What You Eat
How much you eat can sometimes be crucial to the amount of medication
that stays in your body. For example, the amount of nelfinavir
(Viracept) that stays in the body is three to five times greater when
it's taken with a meal than when it's not. Pharmacist Patrick Clay Click has more.
Hepatitis C and Smoking, Alcohol Don't Mix
As if you needed another reason to cut down on the Marlboros and
tequila shots: A study last year found that people with hepatitis C
should avoid smoking cigarettes and drinking alcohol because both
habits can further damage their livers.
AIDS Diagnoses Rapidly Increasing in Washington, D.C.
According to updated 2001 data, Washington, D.C. has a higher AIDS incidence rate than Baltimore, San Francisco and New York, according
to research findings scheduled to be presented on July 28 at the
National HIV Prevention Conference in Atlanta.
U.S. Will Help Pay for Generic Drugs Overseas
The United States plans to purchase low-cost generic antiretroviral drugs as part of President George W. Bush's $15 billion global AIDS
initiative, U.S. officials have announced.
The Changes an HIV Diagnosis Brings
"My granny used to say, 'The only thing that's constant is change.'
I never understood that statement until I became an adult. It became
even clearer after learning I was infected with HIV." Deneen Robinson, an African-American woman and an HIV educator, has been living with
HIV for 11 years.
AIDS-Related Cancer Overview
Although there's been a dramatic drop over the past few years in the
number of HIVers who develop cancer, it's still a concern for many
people with HIV. Dr. Jeffrey Schouten talks about the latest research
on some of the most common AIDS-related cancers, including Kaposi's sarcoma and lymphoma.
