UNITED STATES: Drug-Resistant AIDS Case Remains a Puzzle

Washington Post (02.25.05) - Friday, February 25, 2005
David Brown
At the 12th Conference on Retroviruses and Opportunistic Infections in
Boston Thursday, researchers had few new details on the case of a gay
New York man with drug-resistant HIV that rapidly progressed to AIDS.

The patient has given department investigators the names of his sex
partners, who number in the teens, and about two- thirds have been
contacted, said Lucia Torian, the city's director of HIV surveillance
and epidemiology. The investigators are asking his sex partners to get
tested or, if they know they are HIV-infected, to be tested for drug
resistance. Torian provided no results of testing so far.

Thomas R. Frieden, New York City's health commissioner, announced the
case two weeks ago. He will soon send letters to the labs that process
most of the nation's HIV tests and request that they report to his
department all samples of multi-drug resistant virus found in New York
City residents. Health regulations grant Frieden this power during
disease outbreaks. The order, which will run through May 31, can be
extended, Torian said.

At the conference Thursday, Dr. David Ho, chief of the Aaron Diamond
AIDS Research Center, said the patient believes he was infected in the
third week of October after having unprotected anal sex with multiple
partners. In early November, he experienced fatigue, sore throat, and
malaise - symptoms often seen immediately after infection. By late
December, his CD4 count had fallen from normal (about 650 cells) to
just 80, and he had lost 10 pounds by early February - both indicators
of advanced AIDS.

Johns Hopkins researcher Stephen Gange said records of a large group of
gay men studied in the late 1980s showed that seven out of 10,000 cases
developed AIDS within six months of infection. The New Yorker has none
of the obvious immunological traits that can lead to rapid progression
to AIDS, but subtle host abnormalities have not been ruled out, Ho
said.

Doctors say the discovery of other patients with the same strain and
who also experienced a rapid decline would be evidence that the virus
is unusually virulent and dangerous.

Eradication of the SuperBug

By Martin Delaney

Twelve days after a press conference in New York launched a wave of
hysteria-inducing claims about a virulent new super strain of HIV, the
scientific process has finally had its say. The case of the single patient
followed for about a month after he was shown to be HIV positive was
presented to an audience of two thousand or more scientists at the annual
Conference on Retroviruses and Opportunistic Infections in Boston. This was
the venue that many scientists and commentators said should have been the
first place for presentation of the case, instead of a hastily called press
conference. Unlike the press conference, the presentation at the scientific
meeting was immediately followed by four additional presentations by other
scientists who were asked to put the New York report "in perspective."
"Putting it in its place" might have been a better description of what
happened.

The show started with the somber academic atmosphere typical of such events.
Dr. Ho was the center of attention as the moderator invited him to the
microphone. It was a little surprising to see Ho on call, since the lead
author on the elaborate poster they had been passing around the conference
for days was Dr. Marty Markowitz, not his boss, Dr. Ho. Whatever. Ho made no
mention of the controversy that had been raging since the press conference a
week ago nor made any apology to the thousands of people who had been scared
out of their wits. He did manage to say though that he still stood behind
the decision to go the media. There were, however, a number of obvious
shifts in perspective compared to the things that had been said in the
earlier press conference and the "Alert" sent to physicians. In particular,
Ho was no longer claiming the patient was "untreatable" or even "resistant"
to 3 classes of HIV medications. Instead he mentioned, as had critics, that
the patient was readily treatable with at least two major hi-potency drugs,
Fuzeon and Sustiva. Moreover, he now described the "resistance" as primarily
affecting protease inhibitors, while there was "reduced sensitivity" to some
nucleoside drugs.

Was this is the same case that was described as "untreatable" last week? I
have several friends who would give their left nut to have two hi-potency
drugs they could still use.

Another change of perspective appeared around the question of whether the
supposed rapid disease progression of the patient was due to the virus or
due to other factors, such as the patient's heavy use of crystal meth or to
genetic factors. Last week, it was all due to the virus, stupid. This week,
it seemed there were many possible explanations, just as we critics had
claimed.

Next, he went on to admit that rapid disease progression was nothing new,
nor was transmission of multi-drug resistant virus. Finally, he pointed out,
as if it were a new idea, that a single case did not carry the weight of a
whole cluster of people with similar viral and disease characteristics. I'm
sure I wasn't the only one in the audience that had to resist shouting out
"So why did you call a goddam press conference and scare half the world last
week?"

Dr. Ho finished his talk and passed the baton to a scientist who was to
report on the experiences gained in following thousands of HIV positive men
and women in the MACS (Multiple AIDS Cohort Study) and the WIHS (Womens'
Interagency Health Study). The speaker had polled the two databases looking
to see whether there had been previous cases of rapid disease progression
simile to that claimed in the New York case. Well, of course there were, as
just about anyone the audience could have confirmed even without studying a
database. Still, the databases made the point beyond the shadow of doubt.
Though very rapid progression wasn't common, it has been seen for as long as
anyone has been looking.  Nothing new in New York, apparently,

Next up was a representative of the US military AIDS research, which there
has been plenty over the years. After all, they wouldn't want an army full
of HIV positive people. So the military also has a database tracking such
matters. It's conclusion - they too have seen rapid disease progression,
even somewhat more often in the civilian databases. Moreover, they've seen
transmission of multi-drug resistance. Funny they should mention that. Once
again, nothing new about the New York case.

Next speaker was an expert in the transmission of multi-drug resistant
virus. Perhaps to Dr. Ho's displeasure, he described how the transmission of
single and multi-drug resistant virus, seen worldwide, had increased
steadily between 1996 and 2000 and then leveled off. It happens every year,
apparently with great regularity. So, nothing new about that. But of much
greater interest was data he presented that showed how drug resistant virus
was more difficult to transmit than old fashioned, normal, "wild type"
virus. Virus resistant to a single class of drugs was only about 20% as able
to be transmitted as wild type virus. Multi-drug resistant virus was even
less likely to be transmitted.

Wrapping up the show was a former CDC official, Harold Jaffe, who has been a
player in AIDS prevention work for as long as there's been an epidemic. His
job was to talk about the impact of this new case on issues of prevention.
In short, his answer was there shouldn't be an impact based on single case
riddled with so many uncertainties. He said that based on the data
presented, we don't really know yet whether this was a case of rapid
progression, whether the virus was transmissible, or what's it's prevalence
might be. He directly took on the question of whether it was wise to or
useful at least to employ reports of a case with such uncertainty to create
"fear" that might motivate people to change their evil drug using and sexual
behaviors. His answer, like the ones given to the same question by a few of
the earlier speakers, was simply "NO."   Fear might motivate short term
behavioral change, but it makes a very poor motivator over the long term. It
often leads to people simply not trusting any messages on prevention.

At the risk of giving away my age and musical tastes, the evening's program
reminded me of the last live performance of Pink Floyd's "The Wall,"
performed at the Potsdamer Platz in Berlin shortly after the fall of the
Berlin Wall. Near the end of concert, the giant wall, constructed of huge
Styrofoam blocks, once imposing and a 100 yards wide, came tumbling down one
giant brick at a time. Phony plastic brick by brick, the theory of the giant
new Superbug came apart.

Or shall we say, it was eradicated?

Threats of the Superbug aside, this still leaves us as a community with the
problems of crystal meth and related unsafe sexual activity. But as Gregg
Gonsalves of GMHC angrily shouted into the public microphone at the end of
the SuperBug symposium in Boston, this isn't just a problem of people being
bad little boys. Yes, personal responsibility is one of the issues, but so
are things like cuts in federal funding for AIDS prevention programs, gross
federal meddling in the content of such programs, failure to fund drug
treatment programs, and a society that teaches its gay children to hate
themselves. Is it any surprise to see self-destructive behavior emerge from
this mess?

Hopefully, this weeks episode of "Scare Tactics - featuring the SuperBug" is
over and won't show up in the reruns. I have a lot less confidence though
that any of these other problems will be solved, especially when it's so
much easier to just blame people without offering them the slightest help.
