A new pill could enable people living with HIV to conceive children
through sex without risking the health of their HIV-negative partner.
HIV and pregnancy is not a topic we hear a lot about in Australia. But the incredible success of antiretroviral treatment
(ART) means most Australians diagnosed with HIV assume a long and
healthy life, along with the milestones of sex, relationships and
family.
In 2012-13, 108 children
were born to HIV-positive mothers, up from 50 in 2004-05. While we
don’t have the data for children born to HIV-positive fathers, there are
likely to be many more.
The well-managed use of ART means mother-to-child transmission of HIV is rare in Australia.
For a person living with HIV, however, achieving a pregnancy is not
without its complications. Condoms are central to safe sex – the main
protection against transmission of HIV – but of course condoms also
protect against pregnancy.
For heterosexual people in a sero-discordant relationship (where one
person is HIV-positive, the other HIV-negative), options for conceiving
children have tended to be either expensive or risky. At the expensive
end are fertility treatments, such as sperm washing and in vitro fertilisation.
At the riskier end, many couples take a chance on sex without a
condom. If the HIV-positive partner is on ART and the virus has been
suppressed in their system, then recent studies suggest this can be a relatively safe option.
But a new drug could make this risk virtually negligible. Pre-exposure prophylaxis (PrEP) is a course of a combination ART drug called Truvada that HIV-negative people take to prevent them becoming infected.
Research
has so far shown that, taken correctly, PrEP significantly reduces a
person’s chance of acquiring HIV. PrEP has been described as a sexual game-changer: a pill that re-introduces the possibility of “safe” sex without condoms.
For this reason, the emergence of PrEP has been controversial – particularly within the gay community. In a now-infamous 2012 Huffington Post piece,
writer David Duran coined the term “Truvada whores" – pointing largely
to gay men who, Duran argued, will use PrEP simply to continue having
unsafe sex.
Others have echoed Duran’s sentiment, citing concerns that PrEP
provides licence to be irresponsible, undermining years of effort to
legitimise condom use and risking an increase in rates of other sexually
transmitted infections.
But PrEP has more supporters
than critics. While it might not offer a global solution to stopping
HIV, it certainly presents an effective prevention option for people at
high risk of acquiring HIV.
For sero-discordant couples wanting to conceive children, PrEP is
undoubtedly a game-changer, allowing natural conception with minimal
risk. Evidence
to date supports the safety and efficacy of PrEP for sero-discordant
couples trying to conceive and it’s seen as a sensible choice.
But people living with HIV and their partners still encounter stigma if they decide to have children.
In her book on HIV and pregnancy, Positively Negative, journalist Heather Boerner recounts the story of Poppy Morgan (not her real name), an American woman with a HIV-positive partner. In 2010, Morgan’s doctor refused to prescribe PrEP and told her that if she continued with her plan to conceive a child, she would no longer treat her.
To be fair, in 2010 there was limited information available about
PrEP and this doctor may well have been acting out of concern for
Morgan. But Morgan felt shamed by this encounter and judged for her
sexual choices and maternal longing.
This is not uncommon. In her Australian-based research
with HIV-positive women, Karalyn McDonald found many women had friends
or family who objected to their decision to have children, arguing it
was selfish and put children at risk. One woman in the study told people
she had fallen pregnant accidentally to avoid having to justify her
decision to pursue a second pregnancy.
While Truvada may currently be prescribed to HIV-positive
Australians, its use as a preventive treatment for HIV-negative people
has not yet been approved, though the manufacturer has submitted an application to the Therapeutic Goods Administration.
If approved for use, Truvada will need to be assessed by another body
to determine whether it will be subsidised under the Pharmaceutical
Benefits Schedule. Otherwise the cost will be around A$800 per month.
While PrEP may not radically change the landscape of HIV prevention
in Australia – condoms will always be important – it will certainly
provide a significant new reproductive option for people living with
HIV.
But conception is only the first step toward parenthood. There is a
need to promote respectful understanding of the reproductive and
parenting choices made by people living with HIV. Challenging stigma is
an ongoing concern.
