The impossible choices facing HIV-positive women.
By Celia Farber
Mothering Sept./Oct. 1998
Kris Chmiel is a housewife and mother of two young children, living
in Denver. When she was pregnant with her second child, a movement
had just gotten under way to test all pregnant women in the state of
Colorado for HIV, the virus widely believed to cause AIDS. (Critics remind
us that what is tested for is not, in fact, HIV, but antibodies to HIV.)
She was perfectly healthy and in her first month of pregnancy. She
wasn't worried -- she had been monogamous with her husband for the
past nine years. When the test came back "positive," she literally did
not believe it.
Her doctors strongly urged her to immediately start taking the AIDS
drug AZT, in an effort to prevent transmission to her child. "They
finally wore me down," she says, "even though it was totally against
In her fifth month of pregnancy, Chmiel began taking 500 milligrams
of AZT, a drug that has been routinely given to pregnant HIV-positive
women following a 1994 study -- ACTG 076 -- which claimed efficacy
in reducing the transmission from mother to child. (1) (AZT stands
for azidothymidine and is marketed under the names Zidovudine or
Chmiel's daughter is two years old today, and has twice tested
negative for HIV infection. By the standards of the AIDS
establishment, she is not only a success story, but the very epitome
of medicinal victory -- perhaps the only "victory" in the entire realm
of AIDS research. She is precisely the kind of baby who would serve
as a poster child for those forces that are pushing hard for
mandatory testing, as well as mandatory treatment, and maybe even
mandatory AZT use by all pregnant women -- a "saved" baby.
But to Chmiel, there are strong undertones of regret, anger, and even
despair when she thinks back on her choice to take AZT. Follow-up
HIV tests after her child was born gave results different from the
first one, throwing into question whether she ever did have HIV. One
test was indeterminate, and another was negative. She soon started
doing her own research, and found a paper citing all the underlying
conditions -- as many as 64 -- that can cause a false positive HIV-
antibody test. One of them is pregnancy. (See "How Accurate Is the
HIV Test" on page 60.)
She also became more and more aware of the potential toxic effects
of AZT, which, although it is said to be "safe" for both mother and
child, is a known carcinogen, mutagen, and teratogen -- a drug long
classified as "contraindicated" in pregnancy. For Chmiel, who stayed
on AZT for a year after her child was born, the breaking point with
AZT came when the drug's toxicity became so overwhelming that she
crawled to the bathroom and kept vomiting for hours. "I just couldn't
take it anymore," she says, adding that when she stopped taking the
drug, her health returned.
There are five categories that the FDA uses for pregnancy drug
classification, listed from the safest to most dangerous -- A, B, C, D,
and X. AZT is listed in Category C and is described as a drug in which
"safety in human pregnancies has not been determined, animal
studies are either positive for fetal risk or have not been conducted,
and the drug should not be used unless the potential benefit
outweighs the potential risk to the fetus."
In the case of AZT and HIV, the "risk" is a variable that is
inextricable from a core question that hasn't been resolved, namely,
"Does a positive HIV antibody test predict an inevitable progression
to sickness and death?" Some experts say yes, others say no. (See
"Does HIV Cause AIDS?" page 56.) Several studies, particularly in
recent years, have noted how an increasing number of children born
HIV-positive are growing into adolescence without any sign of
sickness. A study that came out of the 1996 International AIDS
Conference in Vancouver reported that 37 percent of all HIV-
positive babies would never progress into full-blown AIDS. (2) In his
landmark book Rethinking AIDS, Dr. Robert Root-Bernstein states,
"Less than a third of HIV-sero-positive infants go on to develop
It may be nearly impossible to ferret out what precisely we mean
when we talk about children "progressing," because the waters are
clouded from the start. Progressing from what to what? As Root-
Bernstein points out, 80 percent of HIV-positive infants in the US
are born to drug-addicted mothers -- whose immune systems are
severely compromised with or without HIV -- and those babies all
will inherit their mother's immune system. If the mother is sick, the
baby will be sick.
Unfortunately, few research efforts have been aimed at truly
resolving the fundamental question of how HIV, as distinct from all
other factors, affects children, because mainstream HIV dogma
holds that there is no question. If a mother has HIV, she and her child
will be viewed through the lens of HIV, and not seen in the context
of their whole immediate environment -- although, as Root-Bernstein
documents extensively, babies born to HIV-positive mothers often
have identical health profiles to their mothers, whether these
babies are positive or negative. (4)
The unified voice of AIDS research takes a far more simplistic view
of the problem. "There are children, about one third, who we call
long-term nonprogressors," says Dr. Ellen Cooper, principal
researcher of Women and Infants Transmission Study (WITS), an
ongoing federal research program. "We've not followed the disease
long enough to know absolutely, but the thinking now is, there's
nobody who doesn't progress, it's just a question of how quickly you
progress, and how good we are at coming up with new therapies to
help you maintain your health and predict when you're going to
The thought is, there is nobody who doesn't progress...
Where did this "thought" originate? And how is it influencing HIV-
positive women, every day, all around the country? In the fractious,
vast, and complex universe of HIV and AIDS, these women are looking
through a kaleidoscope of information, both in written form and
learned firsthand, and making very difficult decisions about how to
handle the news of a positive HIV-antibody test -- for themselves,
and for their children, both born and unborn.
"Do you think that AZT had any adverse effect on your child?" I ask
"Yes, I do," she says firmly. "She has a very enlarged cranium. That's
typical of most of the AZT babies I have observed."
What she tells me next sounds like a terrible dream. "They're killing
babies," she says emphatically. One young woman who came to
Chmiel for counseling at the dissident AIDS activist group HEAL in
Denver, had watched her child test positive for HIV shortly after
being vaccinated (vaccinations can cause the HIV test to produce a
false positive). The baby was put on AZT, despite the fact that the
mother was HIV negative. Three months later, the baby was dead.
Another mother who contacted Chmiel had a baby with hemophilia,
who had received Factor 8 clotting plasma (yet another possible
source of false positives). After testing positive, the baby was put
on several medications and died after only five months. "That child's
mother is still devastated," Chmiel says. "She believes it was the
drugs that killed her son."
Even when children taking AZT survive, Chmiel firmly believes, the
consequences of the drug use can be dire. "I went to this conference
that they held on HIV and pregnancy at Children's Hospital here in
Denver," she says, "and a lot of the mothers there had taken AZT
during pregnancy, and they had their kids with them. I looked from
one to the other, and every single one of those kids had enlarged
craniums. Their heads looked exactly like my kid's head. They're all
Few, if any, studies in the history of AIDS research have caused such
a momentous shift in policy, medical practice, and zeitgeist as the
one called ACTG 076. To believers, it is perhaps the single greatest
breakthrough in the history of AIDS research; to detractors, it is the
most alarming and radical turn prenatal care has ever taken.
Call up virtually anybody who works within obstetrics, HIV/AIDS,
and pediatrics and they will tell you the same thing: that the
protocol now known simply as 076 -- the study that first caused the
FDA to approve the use of AZT in pregnant women -- has been perhaps
the most unequivocally encouraging news in all of HIV/AIDS
research. Fourteen hundred babies per year in the United States
alone, they say, are "saved" by AZT use, which by unknown
mechanisms is said to reduce maternal transmission of HIV. They
will also tell you that there have been no documented complications
from AZT, and that even if there were, they would pale in
comparison to the dreadful effects of HIV itself.
In ACTG 076, the transmission of HIV during labor was reduced from
25.5 percent in the placebo group to 8.3 percent in the group that
was given AZT throughout the second and third trimesters and
intravenously during labor. The babies in that group were then given
AZT for six weeks after birth. Maternal transmission rates vary
greatly -- in industrialized countries, 25 percent is certainly the
high end. In several European studies, the rate is as low as between
about 7 percent and 14 percent -- levels that are said to correlate
with improved prenatal care. (5) In one quite surprising study from
Malawi, it was found that transmission was closely correlated with
levels of vitamin A in the mother. Those with the lowest levels
transmitted HIV to their babies at a rate of 32.4 percent, while
those with the highest levels had a transmission rate of only 7.2
percent -- a figure lower than the lowest figures attributed to AZT.
(6) And yet, the discourse around this subject is framed inextricably
around the notion that toxic medications constitute the only
legitimate and, for the mother, "responsible" route to reduced
Such pharmaceutical intervention during pregnancy is obviously a
major shift in policy. Following recent disasters -- remember
thalidomide? -- the FDA imposed far stricter regulations on what
women could be exposed to while pregnant -- essentially nothing.
Thalidomide, of course, was prescribed as a sedative in both Great
Britain and Europe in the 1950s. Years later, it was found to have
caused at least 10,000 severe birth defects. Not too long afterward,
DES, a synthetic hormone that was prescribed to women in the
1940s and 1950s to prevent miscarriages, was found to be causing
vaginal cancer in the daughters of the women who had taken it
These two catastrophes produced a powerful impact on both the
public and the medical community, resulting in a total ban on
exposing women to chemicals during pregnancy. In 1990, however,
ACTG 076 broke that policy, opening the medical floodgates for the
chemically promiscuous scenario that we have today, in which
pregnant women are given not just AZT, but multiple combinations
of other drugs -- including the new protease inhibitors -- aimed at
reducing "viral load" of HIV. (This is despite the fact that, as of now,
no safety studies have been done on the possible ill effects of these
protease inhibitor drugs on either mother or child.)
This extreme break in policy can only be explained by the climate of
AIDS and HIV, which dictates that no measure is too extreme, or too
risky, if it results in the perceived diminishment of HIV
transmission. Recently, UNICEF and the World Health Organization
(WHO) launched a drive to get AZT distributed to all pregnant HIV-
positive women in developing countries. But since they lack the
facilities for proper HIV testing, the only possible scenario is that
AZT be handed out indiscriminately. When the plan was first unveiled
years ago, Laurie Garrett, a reporter for New York Newsday,
speculated that, not knowing which women are truly infected and
which are not, "They would have no other choice but to treat every
woman in labor with the chemical."
This speaks volumes about the decline of critical thinking in the era
of AIDS -- it is now considered reactionary, even outright
"irresponsible" to question the wisdom of exposing pregnant women
to such a wide array of mutagenic, carcinogenic, teratogenic agents.
(The new drugs, including the various protease inhibitors, are all of
the above, and are listed in Category C of the FDA's pregnancy
hierarchy.) One researcher I spoke to sounded incredulous when I told
her that this article would look at both sides of the issue.
"Both sides? What do you mean?" she asked.
"Well," I said haltingly, "there are people who are very concerned
about the ramifications of all these pregnant women on AZT and..."
"Not people who work with HIV and AIDS?" she interjected. "I don't
think there's anybody who works with HIV and AIDS who is against
"Not too many," I conceded with a sigh. "But there are some who are
extremely concerned about the long-term effects on both the
mothers and the children."
"Well, we are looking at that, and we are concerned about that. But
the main thing is to deal with the HIV. "
I fell silent, realizing from years of reporting on this issue how
futile it is to argue when the big club of HIV has been pulled out.
Like the child's game of rock, paper, scissors, HIV is always the rock
and the scissors.
"AZT is the only drug with proven efficacy," says WITS's Dr. Cooper.
"But we also know that pregnant women with high viral load are at
most risk of transmitting the virus to their babies. So a few studies
are now looking at the ability of different drug combinations on
reducing viral load during pregnancy. But," she concludes, "the truth
is, nobody really knows what to do."
It is common today for AZT to be referred to as "safe" for pregnant
women. But the FDA never considered it so before and banned
pregnant HIV-positive women from taking it, prior to 076. AZT was
classified as a mutagenic agent, which thalidomide also is, and the
controversy in the early days of AIDS -- the activist outcry -- was
that women were being excluded from all clinical AIDS drug trials.
Indeed they were -- the FDA was rightly concerned about the possible
effects of these potent drugs on future babies.
ACTG 076, which was funded in part by AZT's maker, Glaxo-
Wellcome, was designed to determine whether treating pregnant,
HIV-positive women with AZT during pregnancy would reduce the
rate of HIV transmission from mother to child. That was the first
objective. The second, strangely enough, was to see whether AZT is
safe -- for mother or for child. An 076-trial memo stated that,
"although safety [is] unknown it can be argued that any possibility of
stopping transmission to the fetus outweighs perceived risks to the
"You have to put all this into a framework," says Dr. Kathleen Nokes,
an RN and Project Director of Nursing Persons With HIV/AIDS. "Many
people are angry that these women are getting pregnant. So it's like,
'Well, if the mother is going to have this baby, we will have to
intervene to protect it.' That is the mind-set. And the intervention is
This despite the fact that criticisms have been made of the design
and the conclusions of 076. The study's authors themselves, when
they reported their findings in the New England Journal of Medicine
(NEJM) in 1994 admitted that the efficacy of AZT in reducing
maternal transmission of HIV is "impossible to quantify [absolutely]
because of the very small numbers of infected babies [studied]." They
also noted that the rate of the HIV transmission in the placebo group
was inexplicably high. (7)
And could the results be repeated? It is impossible to say, since the
"overwhelming" results of 076 rendered it "unethical" to ever again
use a placebo control group. In fact, when it later came to light that
studies using placebo controls were underway in Thailand and
Africa, there was an uproar in the medical community that was so
loud several editors from the NEJM quit their jobs over the perceived
immorality of the trials. A preliminary report from the trial in
Thailand, however, showed no difference between the group treated
with AZT and the placebo group in terms of transmission rates. (8)
Like so many of the studies involving AZT, ACTG 076 was terminated
as soon as a benefit was seen on the AZT side. At the study's first
interim analysis, 13 babies (8.3 percent) in the AZT group were
reported to be HIV positive, versus 40 (25.5 percent) in the placebo
group. (A total of 477 women were recruited for the study.) (9)
The popular media trumpeted the news that the discredited AIDS
drug AZT had made an astonishing comeback in a patient group that
had previously been exiled from clinical trials. This was now seen as
the medical community almost honoring women by including them.
The Clinton administration touted the study's surprising results as
proof of an unprecedented breakthrough in AIDS. A kind of wild D-Day
euphoria spread through the OB-GYN community, which now finally
had something hopeful to tell pregnant HIV-positive mothers. This
"science by press release" took hold before any independent review
board had verified the data, and nine months before the study itself
Eventually it came to light that the doctor who had leaked the ACTG
076 story to the New York Times was a paid consultant to the drug's
maker, Glaxo-Wellcome (then Burroughs-Wellcome). Still, the
influential US Pediatric AIDS Foundation and many other pediatric
institutions immediately announced that all HIV-infected women
should be offered AZT, and that this "lifesaving treatment cannot be
ethically denied because of ineffective HIV screening."
In 1994, soon after the results of ACTG 076 were announced,
Congress debated legislation for mandatory HIV testing, with
possible enforced treatment for identified babies. It was rejected by
a narrow margin. But President Clinton recently signed another bill
that makes the testing of all infants born at public hospitals
mandatory, together with counseling to all pregnant women. Groups
that don't comply risk losing millions of dollars in federal funding.
"A lot of otherwise progressive, liberal people have bought into this
issue as one of the babies' rights versus the mothers' rights," says
Marc Elovitz, an ACLU lawyer. "But a mother's rights and a baby's
rights are the same thing."
Meanwhile, AZT has been approved for use not only in pregnant HIV-
positive women, but also in newborns, for whom there previously
had been no "standard of care."
"They have progressed from basic research to 'standard of care' so
fast," says Nokes. "And once it is standard care, that's that. If we
prescribe AZT to your baby, and you don't give it to her, we take you
to court for child abuse."
Many women have had precisely this nightmarish experience.
Jenny Guembes, an HIV-positive mother of a healthy seven-year-old
boy, counsels HIV-positive women for the AIDS Healthcare
Foundation in Los Angeles. "When these pregnant women come here, I
tell them, 'Look, if you have a low viral load, there's a good chance
you won't transmit.' I tell them that I never took anything and my son
is fine. But they want so badly to do everything they can for their
unborn child, that they will take anything. Anything."
I ask her whether she has heard of any cases where women were
threatened with loss of custody over the issue of AIDS drug
compliance, and she recounts the story of a client whose two-year-
old daughter was crying so hard whenever it came time to give her
the AZT that she stopped giving it to her.
"They found out she wasn't giving it to the child," Guembes says, "and
they took her daughter away from her." It took her two years to get
her child back, and she was warned that, to keep her, she would have
to comply with the medical protocol.
"Now she doesn't miss a dose," Guembes says somberly.
The intimidation experienced by women who test positive for HIV is,
in fact, intense. "It's not like with gay men," says Emily Gordon, a
social worker, editor of the newsletter Just Kids, and a former
health consultant to the New York Department of Health. "With
parents, the doctor or social worker will look at the mother and say,
'You love this child? Do you want this child to die?' And she'll walk
out with a prescription for whatever the doctor is pushing at that
"It's shocking, but nobody cares," agrees Terry McGovern of the HIV
Law Project, a group that represents many HIV-positive mothers in
their struggles with the system. "It's far from clear that any
treatments do any good, and yet these women are viewed as baby
killers when they hesitate to give toxic drugs or take them when
McGovern likens the current battle to the reproductive rights
movement. "From a lawyer's viewpoint," she says, "we are squarely
within Roe v. Wade territory here, with the big question of whether
the mother can overcome the doctor's decision not to take AZT."
For her part, Guembes decided not to take any medication while
pregnant or after. (AZT was offered to her years before ACTG 076.)
Today, she remains healthy, as does her boy, who is HIV-negative.
"When people found out I wanted to have this baby," she recalls,
"everybody said that I should have an abortion. Everybody."
That was the informal "standard of care" for all HIV-positive
pregnant women in the past -- they were counseled to have abortions.
Initially, the belief was that 100 percent of babies would inherit
their mother's HIV. Even today, women often are told that the risk of
transmission with AZT is 50 percent. In fact, it usually takes six to
18 months for children who are born to HIV-positive mothers but
who have not been infected with HIV to revert to negative." (10)
Today Guembes doesn't go around expecting to get sick. "I don't think
HIV is the sole cause of AIDS," she says. But her colleagues at the
AIDS organization where she works still pressure her relentlessly to
start taking medications.
"I just smile at them," she says, "and say, 'Nah, not just yet.'"
What I've been hearing from many people who work with women and
HIV is similar to Guembes's story: Growing numbers of these
mothers are intuitively rejecting the medicines. They often pretend
they're taking the drugs and giving them to their children, but in fact
they're stockpiling the pills at home, or flushing them down the
"Mothers will never tell their doctors, but they'll tell me," says
Emily Gordon, the New York social worker. "Parents are often very
much against using AZT. They feel like they are poisoning their kids."
But AZT is only part of the problem -- or the solution, depending on
your particular beliefs -- because now the pharmaceutical companies
are developing new drugs faster, and the FDA is approving them
faster. Despite the total lack of safety or toxicity data, pregnant
women are taking them, and the FDA recently approved several of the
new drugs for use in children. (A few years back, a federal pediatric
trial had to be stopped when children in the AZT-only arm of the
trial started dying much faster than children in the other arms of
the trial, which involved other drugs.) (11)
"These are really tough regimens," admits Dr. Cooper, who
nonetheless believes staunchly that they are effective in keeping
kids alive. "Some of this stuff tastes really bad. Beyond bad. The
worst-tasting medicine used to come as a liquid, Retrovir, and
adults could not tolerate it. They just gagged and vomited. It's now
liquid inside a capsule, but the capsule is really big.
"It's a full-time job giving some of these children their medicines,"
she continues. "They often may be on 15 different drugs, given
multiple times a day, some with food, some without. But," she says,
"I've never seen any kid who's done well without medications."
Gordon, by contrast, says she has seen perhaps the greatest
treatment successes among HIV-positive children who have done
nothing, meaning no toxic drugs, relying instead mainly on
nutritional supplements, medicinal herbs, and generally improved
diets. "I have several HIV-positive kids who have never taken AZT
who are now teenagers," she says.
I ask Cooper whether she thinks that HIV-positive women's attitudes
toward having children are changing. "Probably," she says. "There are
some HIV-infected women who are more likely to have children now.
But an 8 percent risk of transmission is still a risk. It is different
than it was, but it's not zero. An 8 percent risk is a higher risk than
most people would take with other congenital diseases. As long as
the women understand that, we totally support them if they decide
to have a child."
Christine Maggiore, who was pregnant, healthy, and HIV-positive,
found no such support. Searching high and low for a midwife in the
Los Angeles area who was willing to deliver her child at home, she
was turned down by almost everyone. "All this loving, warm, fuzzy
stuff, and then you're still a leper," Maggiore says sardonically.
"Even the head of the Association for Childbirth at Home turned me
down. And this very progressive clinic where they specialize in
lesbian births, they wouldn't even call me back. The ones that did
return my call asked me the same stupid questions in the same
aghast tone: 'Why would you want to have a baby if you have AIDS?'"
Maggiore is quite well equipped to answer that question, having
devoted most of the past six years of her life to deconstructing
what she calls the many "myths" concerning AIDS -- chief among
them that being HIV-positive means you are going to die of AIDS.
Maggiore, author of the booklet What If Everything You Thought You
Knew About AIDS Was Wrong? has been HIV-positive for seven years
and has remained symptom-free. (Her doubts concerning the HIV
paradigm originally were triggered when several HIV tests revealed
different results -- positive, indeterminate, and negative.)
She had a "blissfully uneventful" pregnancy, and a normal childbirth,
at home, with a midwife who was very reluctant, but eventually
agreed. She describes her baby, Charlie, who was exclusively
breastfed for the first eight months of life, as "super alert, strong,
and happy. Everywhere we go, people stop us and say, 'You look
amazing...what kind of vitamins are you taking? You don't look like
you're living with any life-threatening illness.'" Maggiore laughs.
"There was this one lawyer who was threatening to slap an
injunction on me as an unfit mother," she remembers. "But my
friends finally convinced him that I'm as fit as they come."
One of the problems with assessing the true toxicity data from 076
is that they are collected in a "Pregnancy Registry," which is largely
under the control of the company that makes AZT: Glaxo-Wellcome.
But some bits of data have been mined, and they are not exactly
AZT was first tested on minority populations in the United States
and cohorts of pregnant women in the Third World -- the same
populations on whom contraceptives are commonly tested. Prior to
the launch of 076, data on 41 women who took AZT during gestation
was collected and surveyed by the ACTG OB-GYN Working Group. Two
children were born with extra digits on their hands and feet. Other
serious birth defects included low-set ears, misshapen craniums,
and heart defects. (12) Another study, published the same year as
076 in the Journal of Acquired Immune Deficiency Syndrome, studied
AZT in pregnant women in India, focusing on birth defects. Out of
104 pregnant women treated with AZT, there were eight reported
spontaneous abortions, eight therapeutic abortions, and eight babies
(13 percent) born with serious birth defects, including cavities in
the chest, abnormal indentations at the base of the spine, misplaced
ears, heart problems, extra digits, and albinism. (13) Birth defects
generally occur in the population at the rate of 2 to 3 percent of live
births. The results of this investigation were described by the
study's authors, with what appears now to be some considerable
understatement, as "not proving [AZT's] safety" during pregnancy.
Similarly a 1996 study from the American National Institute of
Child Health and Human Development concluded, "In contrast with
anecdotal clinical observations and other studies [showing] that
Zidovudine favorably influences [fetal] weight-growth rates, our
analysis suggests the opposite." (14)
A list of complications caused in animals (rats, mice, dogs,
monkeys) subjected to AZT includes: anemia, bone marrow depletion,
leukemia, T-cell depletion, atrophy of the thalmus gland,
lymphotoxicity, nephrotoxicity, cell death, lung, liver, and vaginal
cancer, retarded development, and, worst of all, fetal death.
As a result of such findings, a 1994 study published in the Journal of
the American Medical Association stated categorically that AZT
taken during pregnancy resulted in an increased rate of structural
"Anecdotally, there certainly have been rumors that some of the
HIV-negative children enrolled in 076 have heart problems," says
Marion Banzhaf, who works with women and AIDS in New York City
as a consultant.
But several doctors working in the field of HIV, AIDS, and
obstetrics, interviewed for this article, insisted that no such
abnormalities have been observed in US babies exposed to AZT in
utero. A faxed copy of an abstract that summarized the results of
ACTG 219, the federal study that is supposed to be following the
babies given AZT during 076, is extremely cursory. "No adverse
effects for [AZT] exposed infants followed for as long as four years
[were found]. While that data are reassuring, continued prospective
evaluations of perinatally exposed infants are critical to assess the
long-term safety of successful...prevention strategies." (15)
"I agree that it's scary that we do not know what the long-term
adverse effects of AZT may be," says Dr. Lynne Mofenson, who co-
authored the CDC's recent Perinatal Transmission Treatment
recommendations. "But it is clear from the data that the adverse
effects so far have been minimal."
"I've never seen any enlarged craniums in the children whose
mothers received AZT," says Dr. Cooper, when I questioned her about
Kris Chmiel's observation.
"We don't yet know what the long-term effects of AZT may be," she
goes on, "but so far we have seen virtually no adverse effects in the
short term. The babies are perfectly normal. I have an unpublished
paper in front of me that looks at the possibility of tumors
developing in these kids. There was not one single tumor. Not one.
And no abnormalities either."
"I mean," she adds, "they have cancers, lymphomas, and other
problems like that, because cancers tend to be more prevalent in HIV
children than in others, but there is no reason to link those cancers
to the AZT." (Studies have shown that the risk for lymphomas is 70
percent higher in adults who have been on AZT.) (16)
"You have to realize," says Nokes, "that they are never going to say
that any serious side effect is 'caused' by AZT, because typically, in
these children, you can find countless other adverse external
factors. Crack. Heroin. Smoking. Alcohol. Hepatitis B and C. So first
you would have to reach the high level of complications that is
caused by all that, and then exceed that by a wide margin, and then
maybe we can start to talk about the adverse effects of AZT."
What also complicates the question is that AIDS, as currently
defined by the CDC, is a collection of at least 40 disparate
symptoms in the presence of an HIV antibody. Critics of the almost
indiscriminate use of both AZT and other pharmaceuticals have long
argued that the drugs used to combat HIV can create some of the
very AIDS-related symptoms they are supposed to help ameliorate.
(17) Glaxo-Wellcome states this fact, too, on page 1170 of the 1998
Physician's Desk Reference: "Serious adverse events have been
reported with Retrovir...[These] pathological changes, similar to that
produced by HIV disease, have been associated with prolonged use of
AZT is, in fact, both an immune suppressant and a potent carcinogen.
It was originally developed during the National Institutes of Health's
Virus-Cancer Program in the 1960s, when it was widely believed
that cancer was caused by an infectious virus. Designed to kill
growing cancer cells by blocking the formation of DNA chains, AZT
not only failed to cure any cancer in tests on mice, but was so
effective in destroying healthy growing cells that the mice died of
extreme toxicity. Studies showed that it caused cancer in any dose
and that it was too toxic for even short-term use. AZT was shelved
for two decades and no patent was ever filed. (18)
At the National AIDS Malignancy Conference held in Bethesda,
Maryland, last year, a research paper was presented that
acknowledged the positive results of 076 in reducing maternal HIV
transmission. "But," the paper continued, "in adult mice, lifetime
AZT administration induces vaginal tumors at a 10 to 20 percent
incidence." The paper's authors went on to specify that "...in female
reproductive organs, the controls had no tumors, and there was a 17
percent incidence of ovarian and uterine tumors at the 25 mg dose.
Compared to other known chemical carcinogens," the authors
concluded, "AZT appears to be a moderately strong transplacental
carcinogen [meaning it's able to cross the placenta]." (19)
Critics of the study, most notably Glaxo-Wellcome, insisted that the
data was irrelevant, because the researchers had given much higher
doses of AZT, proportionally, to their monkey and mice subjects than
would be given to humans. The authors, however, insisted that the
total drug doses given to the animals were quite similar to those
that would be received by any woman who took AZT for about six
months. "The data suggest," the researchers concluded, "that the
[medical] surveillance of [all] AZT-exposed children should be
carried out well into adulthood."
"What's to make us think that there is not going to be some kind of
major price to pay somewhere later down the road for giving AZT to
these babies?" asks Kathleen Nokes. "And I don't mean a minor price,
I mean a major price. All I know is, this drug has been shown to
cause vaginal cancer in rodents. It is affecting the blood of these
infants, causing various abnormalities. The party line up to this
point had been: 'Don't give pregnant women anything' -- especially
coming off of the big thalidomide study, which everyone in the
United States still pats themselves on the back for.
"I don't think we're going to have the answer to the toxicity
questions in just a year or two," she continues. "I think we're talking
more like six years or, seven, eight, even ten years. A lot of
supposed experts are saying, 'Oh come on now, you're overreacting.
This isn't DES.' Well, I've been in nursing for 27 years, and I'm not so
sure about that. I'm not sure that it's not DES."
Nokes does say that she has been reassured somewhat in the past
year or so by the fact that AZT is now usually being given in smaller
doses and for shorter periods of time than in the years immediately
following ACTG 076.
"We don't yet know the long-term effects of AZT or other HIV drugs,
that's true," counters WITS's Dr. Cooper, "and we are looking very
closely at that. But if you compare the terrible risk of contracting
HIV, which is always fatal, to the minimal risks of AZT, I would say
there is no comparison."
This, then, is precisely where today's ideological battle line is
drawn: To those who are convinced that HIV is "always fatal," AZT,
even during pregnancy, is essential. But to a growing number of
people who question that presumption, this now-standard treatment
for nonsymptomatic and risk-free HIV-positive patients -- and their
children -- has come to seem almost diabolical. *
