Editorial The conference "Childhood and AIDS: Rolling Back AIDS in Developing Countries", held in Paris on the 15th and 16th of June, brought together over 300 people to tackle the question of how to scale up treatment, care and support of children living with HIV and AIDS orphans. This month Growing Up Info will take you inside some of the highlights of this conference.
The "Childhood and AIDS" website contains presentations, videos and bibliographies

Participants were struck by several particularly moving stories.
Kerrel MacKay, a 20 year old Jamaican whose father had AIDS described how hard it was for her
to care for her dying father without being able to talk to anyone about this secret illness.
Jeanne Gapiya-Nyonzima, President of ANSS, a care and support organization for PWHAs in Burundi,
has been speaking publicly for over 10 years about being HIV+. But it was during this conference that
she chose to speak about a particularly painful moment in her life "(In 1988) I became pregnant with my
second child. The doctor who I saw at the time knew that my first child was infected. Thinking that he
was doing right, or not really knowing what to do, he decided that I should abort. However the pregnancy
was already quite advanced so I ended up having a hysterectomy which was psychologically devastating. For
years I felt as if I had literally been mutilated. Now, thanks to scientific progress and technology it
is possible for HIV+ women to have children and to protect them against HIV infection. Unfortunately I
will not be able to benefit from these advances because I will never be able to give life"
In the fight against AIDS words can be healing and help to lift taboos and secrets.
In a conference forum but also between parents and children, as the orphan members of the
Ivorian organization Nzrama reminded us during the conference's closing session.

During the conference "Childhood and AIDS", the importance of early HIV diagnosis in
children was often mentioned. Mortality linked to HIV is very high during the first 2
years of life. Common HIV tests (detection of HIV antibodies) are not adapted to the
situation of the infant who carries his/her mother's antibodies sometimes up until the
age of 18 months. CD4 count may have useful diagnostic value for children in this age group,
but PCR tests which detect HIV-DNA or HIV-RNA remain the only way to confirm infection in
young children (not before 6 weeks especially in children who have received ARVs in the context
of PMTCT).
PCR remains expensive and requires specialized reference laboratories equipped with specific
personnel and technology, so it is generally inaccessible to patients who live far from large
African capital cities. The technique of using dried blood spots (DBS) on filter paper is changing
this situation. It makes it possible for the use of PCR to become more widespread, as it requires
equipping a limited
number of reference laboratories and training a smaller number of laboratory technicians.
Simple and risk-free technique: 5 drops of blood taken from the child's heel are placed on
filter paper. This is taken to the reference lab. Government subsidized programs are starting
up for example in Rwanda, Uganda and Ivory Coast, enabling better national coverage.
Limits: The filter paper must be kept dry and protected (plastic bag or cellophane) so as
to prevent them from touching each other during transport. A transport system needs to
be set up to take specimens to the laboratory. Partnerships with postal companies should
be considered. Blood sampling is simplified at the local level, but it requires the lab to
take on a few additional steps/tasks. Remember that if the HIV exposed child is symptomatic,
PCR will only confirm the decision to start ART; and if the child is asymptomatic, two negative
results repeated at a two month interval don't exclude the possibility of the child becoming
infected later on through breastfeeding, if breastfeeding does continue (repeat PCR two months
after weaning). Finally, spreading PCR on the national level is worthwhile only if test results are
given quickly.

We gave you an exercise concerning ARV dosages. Here are the correct answers:
Yacouba - Triple therapy AZT + 3TC + NVP
Dosages AZT 9ml, twice a day -- 3TC 4ml, twice a day --
NVP D1-D14: 4ml, once a day / D15-D30: 6ml (or 7ml), twice a day
Quantities to be given for the first month of therapy AZT 6 bottles/100ml --
3TC 3 bottles/100ml -- NVP 3 bottles/100ml
Isabelle - Triple therapy d4T + 3TC + LPV/r (or EFV but monitor transaminases)
Dosages d4T 20ml, twice a day -- 3TC 1/2 scored tablet, twice a day
-- LPV/r 2,5ml, twice a day -- or EFV 1 tab@200 mg + 2 tabs@50mg to be administered in a single dose in the evening
Quantities to be given for the first month of therapy d4T 6 bottles/200 ml --
3TC 30 pills@150mg -- LPV/r 3 bottles/60ml -- or EFV 30 caps@200mg & 60 caps@50mg
On June 14, Growing Up and Serment Merveil (Congolese NGO) conducted a satellite
workshop on disclosing an HIV diagnosis. The following case came up for discussion.
Cecilia is 8 years old and lives with her maternal grandmother and 3 brothers, the youngest of whom
is HIV+. Her mother died two years ago and her sick father has returned to the village where he was
born. Cecilia, who tested positive after her mother's death, is not aware of her HIV status. She is seen
by a hospital doctor on a regular basis but is not on ART. Her CD4 count is still high. Her little brother
is treated at the same hospital and he is on ART. Lately, Cecilia has been asking a lot of questions to the
hospital staff, "Why do I have to come and see the doctor? Why does the doctor give medicine to my brother
and not to me? How come my other two brothers do not come see the doctor here?"
How would you react if you were faced with these questions?

To add to the resources available on care and treatment of orphans presented in the last
issue of Growing Up Info, we have brought you some new documents from the "Childhood and AIDS"
conference which will help you explore the field further.
First of all CEPED (Centre Population et Développement) publishes a
review of literature on the topic of orphans and
vulnerable children due to HIV/AIDS in Africa. The review includes a
database of 400 bibliographic references
and is divided into 5 chapters: 1. Who are "AIDS Orphans"? - 2. Data sources and measures -
3. The scale of the crisis - 4. Supporting orphans due to HIV/AIDS -
5. Vulnerabilities facing children in families affected by HIV/AIDS
We also recommend another literature review published by ISPED which gives an assessment of the work,
research and most significant local experiences on children affected by HIV, on PMTCT and on pediatric care.
Finally, for those of you who speak French and have access to high-speed Internet, you can consult the work done
by Orphelins Sida International (OSI), "Action plan to support orphans and vulnerable children".
Its first phase is to map the process of "orphanage" and childhood vulnerabilities as well as the different ways to
provide treatment and support of affected children. A second phase will include a discussion and
recommendations that will result from case-studies.
