CHAPTER 6
In this article, we will mainly discuss
the issue of so-called mother-to-child-transmission (MTCT/MTC), given
the extraordinary volume of publicity around this matter. In this regard,
we will concentrate on the drug "Nevirapine", which is said
to be the most effective for this condition, the cheapest and the easiest
to administer.
On HIV/AIDS treatment generally, we will
only cite some comments made by people who should know what needs to be
known about this matter, namely, the scientists.
In its edition of May 10, 2001, The New York
Times reported that:
" A leading maker of drugs that fight
AIDS, the Agouron Pharmaceuticals division of Pfizer, and its agency,
CCA Advertising in New York, are changing a consumer campaign they recently
introduced for the drug Viracept. They are adding cautionary words that
such drugs are not a cure for AIDS nor do they prevent the spread of HIV,
the virus that causes AIDS. (Our emphasis.)
" The change is coming two weeks after
the (US government) Food and Drug Administration sent letters to eight
makers of anti-AIDS drugs, including Agouron, warning that these products
could no longer be advertised without noting their limitations."
A press statement released by the US government
health agencies on February 5, 2001, quotes Dr Fauci, director of the
National Institute of Allergy and Infectious Diseases, as saying:
" Although antiretroviral therapy has
provided extraordinary benefits to many patients, we know we cannot eradicate
HIV infection with currently available medications.We are very concerned
about a number of toxicities associated with long term use of antiretroviral
drugs," says Dr Fauci. " Particularly alarming is the alteration
of fat metabolism that can emerge during treatment. We are seeing an increasing
number of patients with dangerously high levels of cholestorol and triglycerides.The
bad news is that we must now find ways to deal with unanticipated toxicities,
including the potential for premature coronary disease."
On February 7, 2001, Reuters reported:
" One of the first studies to look at the success of HIV treatment
in inner-city patients from the time of diagnosis reveals a dire situation,
a doctor working in Atlanta, Georgia, said here on Tuesday at the 8th
Conference on Retroviruses and Opportunistic Infections. His study found
that only 1 in 10 patients newly diagnosed with HIV achieved a reduction
in virus in blood to "undetectable" levels - a major goal of
treatment.
" One year after being diagnosed, 24
patients (18%) had died, del Rio reported. Of the 103 eligible to attend
an outpatient clinic, the majority discontinued treatment after a few
months.
" Nobody has really looked at the number
of HIV-infected patients who achieve successful viral suppression with
antiretroviral therapy starting from the time of diagnosis, del Rio told
Reuters Health. Other studies have looked at the success of antiretroviral
therapy in those patients who remain in care.
" 'What is striking to me, is that we
think that those are the problems of Africa - but they're the real problems
of our country. I tell people I work in a developing country called inner-city
Atlanta,' del Rio said.' "
In "The AIDS Reader" 11(5): 236-237,
2001, its editor, Jeffrey Laurence, MD, writes:
" One must recognise that few clinicians
anticipate that current ART (anti-retroviral therapy) regimens will extend
the lives of HIV-infected patients more than a few years. Viral resistance
and drug side effects undermine their utility. Indeed, in 1 of the 2 US
economic studies, quality-adjusted life expectancy rose only 1.84 years
for those initiating ART at higher CD4 cell counts; for those with low
CD4 cell counts, it was not much better. Although this degree of life
gained proved similar in magnitude and cost to that of thrombolytic therapy
in myocardial infarction, such comparisons are irrelevant where more than
90% of HIV infections occur - in the developing world."
In another report dated May 25, 2001, Reuters
said:
" Treatment with highly active antiretroviral
therapy, or HAART, often damages the liver, leading many HIV-infected
patients to halt treatment, according to study results presented in Atlanta
this week.
" Regardless of drug class or combination,
there appears to be 'an across-the-board high rate' of severe liver toxicity.
" Regimens that contained drugs called
nonnucleoside reverse transcriptase inhibitors, especially nevirapine
and efavirenz, were particularly hard on the liver.In November, the US
Food and Drug Administration issued an alert for nevirapine based on reports
of liver toxicity." (Our emphasis.)
Addressing the 39th Annual Meeting of the
Infectious Diseases Society of America on October 25, 2001, Dr William
G. Powderly, said:
" The safety of PEP (postexposure prophylaxis)
was called into question earlier this year with reports of nevirapine-associated
liver toxicity in otherwise healthy recipients, resulting in a recommendation
that nevirapine not be used for PEP."
During the Durban XIII International AIDS
Conference in 2000, the Chicago-based NGO, the International Association
of Physicians in AIDS Care (IAPAC), issued the following statement, datelined
"Durban, South Africa, July 11:
" Today researchers at the XIII International
AIDS Conference presented preliminary data suggesting didanosine (Videx,
also known as ddI) and stavudine (Zerit, also known as d4T) are safe,
effective and tolerable alternatives to existing drug therapies in preventing
mother to child transmission (MTCT) of HIV. Videx and Zerit are part of
the reverse transcriptase inhibitor class of anti-HIV drugs and are proven
to safely reduce HIV replication among infected adults and children. (Our
emphases).
" The AI455-094 pilot study conducted
at the Chris Hani Baragwanath Hospital in Soweto, South Africa randomised
373 HIV-1 infected pregnant mothers to an orally administered regimen
of ddI, ddI+d4T, or zidovudine (AZT).
" These early data show the potential of Videx and Zerit to be safe,
tolerable and effective in preventing the transmission of HIV from infected
mothers to their unborn children when compared to existing medical interventions,"
said Dr Glenda Gray, co-director of Perinatal HIV Research Unit at Chris
Baragwanath Hospital in South Africa.". (Our emphasis).
" Zerit and Videx are manufactured by
Bristol-Myers Squibb Company, a global health and personal care company
whose mission is to extend and enhance human life." (Our emphasis).
On January 8, 2002, the US Wall Street Journal
reported as follows:
" While the Food and Drug Administration (FDA) conducts a review
of the two products, Bristol-Myers Squibb has issued a warning to AIDS
doctors around the world cautioning that two of its AIDS drugs, Zerit
and Videx, should be used sparingly in pregnant women after the deaths
of three expectant mothers who were taking the medications. An FDA official
suggested it is possible that although toxicity problems affect other
drugs in the nucleoside analogue class - which includes the GlaxoSmithKline
drugs AZT and 3TC - the reaction to a particular enzyme is stronger for
the two Bristol-Myers products than for other drugs in the class. The
deaths could have far-reaching consequences than just the potential withdrawal
of the drugs and the passing of the women: two of the deaths occurred
in clinical trials abroad, with one of those deaths taking place in South
Africa, where the issue of AIDS drugs is particularly volatile. The women
died of lactic acidosis, a rare but recognised comp!
lication associated with the nucleoside analogue class, and seven other
cases of nonfatal lactic acidosis have been reported among pregnant women
taking either a combination of Zerit and Videx or of Zerit with 3TC."
(Our emphases.)
Dr Glenda Gray features regularly in our
media as a much-quoted and generally believed expert who denounces our
government for its cautious approach to the widespread use of anti-retroviral
drugs. In the IAPAC statement, she is quoted as endorsing Videx and Verit
as being better than AZT and nevirapine in the context of MTCT.
She shared this view with the NGO, IAPAC,
which described the company producing Videx and Zerit as "a global
health and personal care company whose mission is to extend and enhance
human life." Despite the undisguised competition with AZT in the
IAPAC report, nothing is said about the legitimate commercial mission
of Bristol-Myers Squibb to maximise its profit - to attend to the bottom
line!
This company has now admitted that its products
are not the "safe, effective and tolerable alternatives to existing
drug therapies in preventing mother to child transmission (MTCT) of HIV"
that Glenda Gray and IAPAC claimed they were. Pregnant women have died
because they were subjected to these "safe, effective and tolerable
alternatives"! Reportedly, one of them is a black woman, on whom
Glenda Gray experimented with toxic drugs at Chris Hani Baragwanath Hospital.
Interestingly and ironically, this year the
US Kaiser Family Foundation (KFF) conferred the Nelson Mandela Award for
Health and Human Rights on Dr Glenda Gray (and Professor James McIntyre)
for the supposedly 'outstanding' work she has done on MTCT. Nothing was
said of the women who died!
Of Gray and McIntyre the KFF says:
"Dr Glenda Gray and Professor James
McIntyre are co-founders and co-directors of the Perinatal HIV Research
Unit at the Chris Hani Baragwanath Hospital, the largest in the world.The
Perinatal HIV Research Unit is one of the world's leading centers of excellence
for research and implementation activities in the field of mother-to-child
transmission of HIV and has been at the forefront of work in this field.Responding
to the changing needs around HIV/AIDS, the Unit has expanded to undertake
work in antiretroviral treatment for adults and children, psychosocial
support issues, HIV and tuberculosis and HIV vaccine trials.The Mandela
Award.is given annually in recognition of extraordinary dedication and
achievement in improving the health of the disadvantaged populations in
South Africa and the United States."
Bristol-Myers Squibb must have been mightily
pleased that their own Glenda Gray, enthusiastic promoter of Videx and
Zerit, was honoured with so prestigious an award for improving the health
of the disadvantaged populations in South Africa and the United States!
A number of questions that demand urgent answers arise in the context
of the foregoing.
Why was the South African and global public
told lies?
Since Glenda Gray must be held accountable, how has this been expressed?
Since Chris Hani Baragwanath Hospital must
be held accountable, how has this been expressed?
Since the Medicines Control Council (MCC),
which presumably approved the Glenda Gray clinical trials, must be held
accountable, how has this been expressed?
How has the Gauteng Provincial Government
accounted for its own conduct in this affair?
How have the national Ministry and Department
of Health for their own conduct in this affair?
Have Videx and Zerit been licensed by the
MCC for any indication, and if so, on what evidence?
What reports, in any, have been submitted
to the MCC on the safety of these drugs if they are generally available
in our country?
People have died as a result of using these
drugs. The highest US regulatory authorities have instituted processes
to study their impact. As of now, we do not know what the WHO and UNAIDS
have to say.
But we need to know what our own regulatory
authorities have to say. We also need to know whether our own health authorities
have communicated to everybody concerned the substance of what the Wall
Street Journal reported. What are the answers to all the questions that
have been posed?
Last year, the periodical ANC Today posed
other questions relating to another clinical trial conducted in our country.
This concerned a microbiside that was touted as being potentially effective
in the context of MTCT.
We quote this article in full because of the important issues it raises,
especially in the light of what we have just said with regard to Videx
and Zerit.
" DRUG TRIALS"HIV/AIDS, profit and fundamental human rights"THE
STORY OF NONOXYNOL-9, known as N-9, an active ingredient used in chemical
barriers to HIV and STD transmission, raises disturbing questions about
research ethics, drug company profits and the role in Africa of international
development agencies."Products designed to provide a chemical barrier
to HIV and STD transmission, such as N-9, are called microbicides."
According to a circular of the US Centres for Disease Control (CDC), dated
4 August 2000: "From 1996 until May 2000, UNAIDS sponsored a study
of the effectiveness of a gel which contained 52.5 milligrams of N-9.,
compared to an inactive gel. The study was conducted in several locations
in Africa. Nearly 1,000 HIV-negative commercial sex workers were enrolled
in the trial, and all women were counselled to use condoms consistently
and correctly. In addition to condom use, the women were asked to use
a vaginal gel each time they had intercourse.
Half of the women were provided a placebo (non-active) gel and half of
the women received an N-9 gel.""Later, we will report on the
results of this trial and the recommendations of the CDC. But before this,
we have to give a short account of the history of N-9."
The conclusions of a 1992 N-9 study were published in the journal JAMA
1992 July 22-29; 268(4):477-82 and stated that: "Genital ulcers and
vulvitis occurred with increased frequency in nonoxynol 9 sponge users.
We (who conducted the trial) were unable to demonstrate that nonoxynol
9 sponge use was effective in reducing the risk of HIV infection among
highly exposed women."
The trial referred to here was conducted among sex workers in Kenya in
1992."The results of another study were published in 1993 in the
International Journal on STD and AIDS 1993 May-June; 4(3):165-70. This
study concluded that: "The rate of epithelial disruption (genital
ulcers) for women using N-9 4/day was five times greater than that of
placebo users.""After another study conducted in Kenya, the
Journal of Infectious Diseases 1991 February; 163(2):233-9, had concluded
that genital ulcers were associated with increased risk of HIV-1 infection."
By the time UNAIDS began its studies in 1996, published scientific knowledge
was that:
· genital ulcers increased the risk of HIV infection;
· the use of N-9 increased the incidence of genital ulcers; and,
· more frequent use of N-9 led to a higher incidence of genital
ulcers.
"The August 2000 CDC circular to which we have referred said that
the results of the UNAIDS trial were reported at the 2000 Durban International
AIDS Conference, as follows:
"At the end of the trial, researchers found that the women who used
N-9 gel had become infected with HIV at about a 50% higher rate than women
who used the placebo gel. Further, the more frequently women used only
N-9 gel (without a condom) to protect themselves, the higher their risk
of becoming infected. Simply stated, N-9 did not protect against HIV infection
and may have caused more transmission. Women who used N-9 also had more
vaginal lesions, which might have facilitated HIV transmission."
"As we now know, these precise results of N-9, announced in 2000,
were already publicly known by 1993. And yet UNAIDS began its trial in
1996, knowing that N-9 increased the risk of HIV infection, especially
among those who might use the microbicide with high frequency, such as
prostitutes."
Despite this knowledge, after the results were announced at the Durban
AIDS Conference, Dr Joseph Perriens of UNAIDS could still say: "We
were dismayed to find out that the group using N-9 gel had a higher rate
of HIV infection than the group using a placebo."
"South Africa was one of the African countries in which UNAIDS conducted
its trial. In a press release issued in Durban on 12 July, 2000, an organisation
named AEGiS reported that the sites for the South African trial were Durban
and Johannesburg.
"It also reported that the Principal Investigators responsible for
the trial in these two cities were, respectively, Dr S. Salim Abdool Karim
and Dr Helen Rees. At the same time as he was leading investigations into
the efficacy of a chemical compound that was known to be extremely harmful,
Dr Karim was head of AIDS Research at our Medical Research Council.
For her part, Dr Rees was Chairperson of the Medicines Control Council,
the body charged with the responsibility of licensing drugs and medicines.
"The Business Day edition of 13 July 2000 reported Dr Rees as 'caution(ing)
that the (negative) results were not conclusive and more work needed to
be done on the issue. She pointed out, for instance, that it was possible
that the group using the placebo (or substitute with N-9) may have been
exposed to a more active microbicide.'
Presumably by saying that "more work needed to be done", she
meant that more women needed to be exposed to the highly toxic N-9."In
its edition of August 14, 2000, the Washington Post reported that:
"Two U.S.-funded studies involving nonoxynol-9 are underway in African
women at risk of HIV. One, sponsored by the Agency for International Development
to test the ability of nonoxynol-9 gel to prevent sexually transmitted
diseases among a group of women in Cameroon, is due to be completed in
September. The other, a study sponsored by the NIAID to look for protection
against HIV in women in Zimbabwe and Malawi, is getting underway.
In light of the disturbing findings, reported last month at the 13th International
AIDS Conference in Durban, South Africa, researchers have abandoned plans
to test nonoxynol-9 in that study, said Ward Cates of Family Health International,
a non-profit health research organisation that is co-ordinating the project.
Cates said there is no evidence that nonoxynol-9 is harmful to women when
used as a contraceptive. Nonoxynol-9 is a detergent that is a contraceptive
and a microbicide (or germ-killer).""It is puzzling that Cates
should have found it necessary to promote the use of N-9 as a contraceptive,
to soften the impact of the negative results announced in Durban.
"We do not know whether the US-funded trials in other African countries
represent the "more work" to which Dr Rees referred."The
gel mentioned in this article is produced by a US company called Columbia
Laboratories Inc and is marketed as Advantage-S.
According to the Wall Street Journal, after the N-9 trial results were
announced in Durban, Columbia shares 56%, to $5.75. The paper also reported
that, nevertheless, President and CEO of the company, Mr William Bologna,
said the negative N-9 results "may not be scientifically meaningful."
"In a press release dated March 20, 2000, Columbia Laboratories Inc
said: "Prospective investors are cautioned that any.(Columbia) forward
looking statements are not guarantees of future performance and involve
risks and uncertainties, and that actual results may differ materially
from those projected in the forward-looking statements (of the company).
Such risks and uncertainties include, among other things, the successful
timely completion of the study now being conducted by the UNAIDS group."
"Despite this cautionary note, Columbia
Laboratories Inc could not avoid the retribution of either the market
or its shareholders. According to the Wall Street Journal, not only did
its share price fall dramatically, but it was also sued by its shareholders.
The shareholders charged that insiders sold more than $1 million in stock
at inflated prices before the results were announced.
"This is a highly disturbing story that
has directly affected us as a country. It raises a number of questions
that require urgent answers, some of which are:
· Why did the MCC approve N-9 trials
knowing the toxic effect of this compound?
· Why did Drs Karim and Rees assume the role of principal investigator
given the positions they occupied in the state medical institutes?
· What other trials related to HIV/AIDS have been and are being
carried out in our country?
· What impact have these trials had on the health of the subjects
recruited to participate in these trials?
· Why was the N-9 trial conducted only in African countries (and
Thailand) and not the United States, which also has prostitutes?
· What measures have been taken to care for the prostitutes used
in the trial, who suffered genital lesions and turned HIV-positive as
a result of the use of N-9?
· What measures have been taken to care for other people whose
health might have been adversely affected as a result of other trials?
· Why did UNAIDS decide to use our people as disposable objects
who could be exposed to N-9, when UNAIDS knew that N-9 had been proved
to be toxic?
· What steps has UNAIDS taken to look after the people whose health
has been seriously undermined by its wilful activities?
· What will our government do to ensure that this serious matter
is attended to?
· Has the attention of the UN Secretary General, the UN Security
Council and the General Assembly been drawn to these UNAIDS activities?
· What steps has UNAIDS taken to ensure that especially the developing
countries discontinue and do not allow any N-9 trials?
· What role did our Ministry and Department of Health play in the
N-9 matter?
· What role have our Ministry and Department of Health played and
are playing to ensure that ethical norms are observed in the conduct of
all drug trials in our country, and that the poverty of our people is
not exploited to test dangerous drugs here, in a manner that would not
be allowed in the developed world?
· Has the informed consent of those who have been involved in the
drug trials been obtained and what steps have been taken to ensure that
those involved are truly properly informed?
· What measures have been taken to ensure transparency and a system
of accountability with regard to the drug trials?
· Once the efficacy and safety of drugs previously tried in South
Africa has been established, and these drugs accordingly registered, what
steps have been taken to ensure that these drugs are available at affordable
prices to our people?
"All these questions, bearing on the very lives of our people, require
urgent answers."The story contained in this article speaks of our
vulnerability as an African country to the anti-human activities of some
corporate forces. It also speaks to our own capacity, as South Africans,
willingly to co-operate in the promotion of these activities. It tells
a story of how easy it is for some, further to entrench the abuse of already
abused African women - this time in the name of science and health.
"Dr Rees, Chairperson of the MCC, argues that 'more work' needs to
be done on N-9 because the negative results announced in Durban 'were
not conclusive'. This sentiment is echoed by the CEO Bologna of Columbia
Laboratories Inc., who says that these negative results 'may not be scientifically
meaningful.'
"On the other hand, the CDC says: "However, given that N-9 has
now been proven ineffective against HIV transmission, the possibility
of risk, with no benefit, indicates that N-9 should not be recommended
as an effective means of HIV prevention."
"What we ask is - what else about HIV/AIDS is more about profit and
less about the health of our people. Time will tell."
To this day, the important issues raised
in this article have not been answered. We do not know how many of our
people have died as others, such as those at Chris Hani Baragwanath Hospital,
conducted experiments on our people or "treated" them, relying on dangerously
tendentious results of clinical trials and MCC approvals of trials sponsored
by the pharmaceutical companies.
