and Death Decisions

In August 2002, the UK Human
Fertilisation and Embryology Authority (HFEA) rejected an
application from Michelle and Jayson Whitaker to use an in
vitro fertilisation (IVF) 'tissue type' technique, which
would have allowed them to have a child who would be a genetic
match for their son Charlie.
Three-year-old Charlie suffers
from a rare blood disorder, diamond blackfan anaemia, for
which he has to undergo painful day-long blood transfusions
and daily injections. A brother or sister with the same tissue
type as Charlie could donate the cells that could cure him.
Yet in December 2001, the
HFEA gave the go-ahead for Raj and Shahana Hashmi to use IVF
to produce a child who would be a tissue match for their son
Zain, who suffers from the blood disorder beta thalassemia.
These two cases look the same.
Both sets of parents had a chronically ill child, who could
die without treatment from a donor; both wanted to have a
second child who could provide donor cells. Both sets of parents
came across as normal, loving parents, who wanted the best
for their families.
How could the HFEA allow one
and reject the other?
In a press release dated 1
August 2002, the HFEA's chief executive defended the decision
to reject the Whitakers' application on the basis that it
'does not meet the carefully considered criteria laid down
to ensure that the procedure is lawful and ethical' (1).
According to these criteria,
laid down around the time of the Hashmi case in late 2001,
pre-implantation genetic diagnosis (PGD) can only be used
in cases where the embryo being selected was itself at risk
of inheriting the genetic disorder: the Hashmis' was, the
Whitakers' wasn't.
The HFEA also said that its
decision was in accordance with public opinion, which approved
of PGD to avoid inherited genetic disorders, but not for other
reasons. The HFEA press release cited the 'results of a public
consultation on the acceptability of PGD' (2).
While the HFEA claims that
its criteria for the use of PGD are based on careful ethical
reasoning and researched public opinion, they actually rest
on more shaky foundations. The Whitaker decision also suggests
a suspicion of parents' motives, and a reluctance to allow
parents to decide what is best for their children.
Pre-implantation genetic diagnosis
(PGD), the technique the Whitakers wanted to use, involves
the removal of one or two cells from an in vitro embryo
about three days after fertilisation, before choosing which
embryo to implant in the womb. The DNA from this cell can
then be tested for a series of genetic disorders. At the same
time, it can also be tested for tissue type.
The stem cells that could
be used to save the lives of Charlie and Zain could be taken
from the umbilical cord blood of the baby - a procedure that
has no deleterious effect upon the welfare of the fetus. In
some cases, it might be necessary to take the donor cells
from the child's bone marrow - this is a more invasive procedure,
which is protected by a separate set of regulations.
The HFEA claimed that its
decision in the Whitaker case was based on 'ethical' criteria.
But the Whitaker decision sparked much controversy and discussion
among the media, the medical profession and ethicists.
John Harris, professor of
bioethics at the University of Manchester, said: 'My view
is that the decision is unethical. It may cost the life of
a child. It is seriously morally wrong and very sad.... Whenever
we can make things different, we have responsibility for the
outcome. If that child dies, it would not have died a natural
death - it would have died because of the decision of the
HFEA, and the death will be their responsibility.'
Dr Mohammed Taranissi from
the Assisted Reproduction and Gynaecology Centre in London
told me that, 'if anything is to do with helping cure an illness
or a disease, I don't have an ethical problem with it'.
More to the point, the HFEA's
decision went against the recommendation of its own ethics
committee.
The use of PGD to produce
tissue donors was considered in detail by an HFEA ethics committee,
a sub-group of the authority, and this committee decided that
tissue-typing should be allowed in cases where a sibling is
suffering from a life-threatening condition - even if, as
in the case of Charlie Whitaker, the condition is not inheritable.
The report produced by the committee, published on 22 November
2001, had been available from the HFEA's website (3).
It has since been removed.
In many cases the committee's
report provides a series of arguments against the HFEA's
justifications for its decision.
The HFEA's 1 August press
release in response to the Whitaker case said that the restriction
of PGD for tissue typing was 'consistent with the terms of
the Human Fertilisation and Embryology [HFE] Act (1990)' (4).
One part of this Act states that all treatments must be in
the welfare of the child. The minutes for a HFEA meeting on
29 November 2001 (which are available from its website), where
the authority decided upon the criteria for PGD, note that:
'Members felt that to allow PGD for tissue typing alone would
run contrary to the requirements of the welfare of the child
assessment.' (5)
But the HFE Act's statement
on the welfare of the child reads: 'A woman shall not be provided
with treatment services unless account has been taken of the
welfare of any child who may be born as a result of the treatment...and
of any other child who may be affected by the birth.' (6)
In its report, the HFEA ethics
committee gave a number of cases in which the use of PGD for
tissue typing could be seen as being in the welfare of the
child. It notes that 'it is certainly possible that it is
in the interest of the putative child to be able [to] save
the life of its sibling...thereby saving its family from the
turmoil of bereavement, preserving companion siblings, etc'
(7). A child is born into a family environment,
and it is in its 'interests' that the family environment is
as happy as possible.
The minutes for the HFEA's
29 November meeting that decided against the use of PGD for
tissue typing alone note that: 'concerns were expressed about
the psychological burden that may be placed on a child who
was an "engineered" match as [opposed] to a "natural"
match.' (8)
But why should this knowledge
cause a psychological burden? On the contrary, it could make
a child feel special to know that he was chosen to save the
life of his brother or sister. Far from setting the second
child against the first, the use of PGD for tissue typing
could actually help cement the bonds between family members.
Also, the 'welfare of the
child' clause allows for consideration of the welfare of 'any
other child who may be affected by the birth' - a clause that
would clearly apply in the case of Charlie Whitaker.
The ethics committee also
noted that just because parents have a second child who could
act as a donor to a first child, this does not mean that they
will view the second child instrumentally, as little more
than a useful source of stem cells: 'the Committee agrees
that the element of utility in the parents' decision to conceive
clearly does not rule out their benevolent intention to love
and care for the child.' It also noted that 'tissue donation
is not in itself a problematic reason for having children
and is certainly no worse than other common reasons' (9).
The HFEA's 1 August press
release in response to the Whitaker case also cited a section
of the HFE Act, which states that a license may only be granted
for 'practices designed to secure that embryos are in a suitable
condition to be placed in a woman or to determine whether
embryos are suitable for that purpose' (10).
But this law could potentially
be interpreted liberally or conservatively. What exactly does
it mean to say that the embryo should be in a 'suitable condition
to be placed in a woman'? It could mean 'suitable' from the
embryo's point of view, in order that the embryo develops
and is born as a normal and healthy child. The abstract embryo,
from the strict point of view of its own welfare, doesn't
mind what tissue type it is - although it would want to be
born free of genetic disorders.
However, 'suitable' could
also be seen from the point of view of the family into which
the second child is being born. For the parents and for the
chronically ill child, tissue type is very important in deciding
upon the suitability of the embryo to be implanted.
John Harris puts this issue
of selecting embryos into some context. 'In IVF, mothers have
more embryos than they may implant legally, or indeed ethically.
A woman has 6, 10 or 12 embryos; but they only implant three.
Surely it is better to choose on the basis of rational or
humanitarian reasons, rather than for non-rational reasons?
No embryo has an entitlement to be implanted.'
The recommendations of the
ethics committee's paper were rejected by the HFEA in its
29 November meeting. According to the HFEA, full meetings
of the authority rarely last for more than half a day; and,
according to the minutes for 29 November, this meeting involved
many other items. The minutes state that 'members noted the
contents of this [ethics committee] paper', but went on to
note a series of concerns (including the 'psychological burden'
and 'welfare of the child' arguments) before concluding that
'it was agreed that tissue typing using PGD should only be
offered where PGD was already necessary to avoid the passing
on of a serious genetic disorder' (11).
Yet when she announced this
decision on 13 December 2001, then HFEA chair Ruth Deech said,
'We have considered the ethical, medical and technical implications
of this treatment very carefully indeed' (italics added)
(12).
The ethics committee seemed
to work on the assumption that people have a right to make
the decisions that affect their family, and that the state
should only interfere as a final measure. 'There is a presumption
in law that people should be free to exercise their rights
in areas of activity that most closely affect themselves and
their families', the ethics committee stated in its paper.
Given that it is technically possible to select an embryo
with certain genetic characteristics, the commission said
that the issue to decide was whether it would be 'morally
justifiable for the state to withhold this choice' (13).
By contrast, the HFEA's decision
not to allow PGD for tissue typing alone seems to involve
the opposite assumption. The onus is on the parents to prove
why they have the moral right to have the choice - not on
the state to prove its moral right to withhold the choice.
So HFEA chair Ruth Deech's 13 December statement said that
PGD for tissue typing would only be used 'in very rare circumstances
and under strict controls' (14).
The ethics committee also
seemed to work on the basis that reproductive morality and
ethics involves families, not individuals with narrowly opposed
interests. If you have in mind a fetus with no interests other
than to want to be born healthily, and parents with no interest
other than to want a source of stem cells, then allowing PGD
for tissue-typing would seem most unethical. It would indeed
make the second child a 'means to an end, not an end in itself'.
But the HFEA's judgement that
PGD for tissue typing would go against the 'welfare of the
child' suggests instrumental and selfish relationships between
family members. Here, there seems to be an idea that the fetus
needs protecting from the manipulations of its parents.
Furthermore, the HFEA's suggestion
that its decision was based on the rock of public opinion is
not backed up an examination of its public consultation. In
one question, respondents were asked whether they agreed with
the current practice that PGD should be licensed 'for a limited
number of specific serious inherited conditions', and they were
given the options: 'Yes', 'No - greater restriction needed',
or 'No - less restriction needed' (15). Seventy-four
percent said 'yes', 20 percent said greater restriction, and
eight percent said less restriction.
The consultation did not explicitly
ask respondents what they thought about using PGD for tissue
typing - and it certainly didn't illustrate this question
by using a case like the Whitakers', which would have helped
bring the issue to life.
The HFEA doesn't really know
what the public thinks about the issue. If anything, it is
more likely that its decision to limit the use of PGD for
tissue-typing was influenced by what it thinks the public
thinks. Perhaps the authority decided to plump for the
more restrictive regulation because it was nervous about sparking
off fears about 'designer babies'.
After the Whitaker decision,
however, the tabloid press jumped the other way, expressing
outrage that this family was being denied access to a technique
that could save Charlie's life. 'The sick little boy science
won't save', read the frontpage headline in the Daily Mail
on 2 August 2002.
The outcome of the HFEA's
criteria for restricting PGD is a mess. 'They have made two
decisions that are exactly the opposite of each other. This
reflects the fact that they don't really know what to do',
Dr Mohammed Taranissi told me. 'They are sitting on the fence,
picking and choosing.'
This decision to limit PGD
for tissue typing should not go unchallenged. We have the
technology available to save children's lives, yet doctors
are not able to use it. 'What we are talking about here is
a life-threatening situation', says Taranissi. 'All that we
are trying to do is cure an illness. If somebody has a problem
with this then they have a problem with medicine itself.'
But even if the HFEA had based
its decision on well-researched public opinion polls and the
deliberations of ethics committees, it still would have been
the wrong one. It is couples who should decide when and how
they want to have children - and it is they who are best placed
to decide what is in the best interests of their family.
As the HFEA's ethics committee
said in its report, 'There is a presumption in law that people
should be free to exercise their rights in areas of activity
that most closely affect themselves and their families'.
This is an important presumption,
for any society that values freedom. But by extension, perhaps
this argument calls into question the existence of the HFEA
itself - at least in its present form - as a body that regulates
and restricts the fertility treatment that individuals and
couples are able to use.
