Appendix: Overview of Saskia’s life with DBA
August 2001
Saskia born
2001 onwards
Monthly blood transfusions for Saskia from birth, though had a year-long
break trying steroid treatment which failed. Also trialled another drug which
failed. From age 3, nightly night-long infusions via needle of another drug to
alleviate iron-overload problems.
2003
Second child born happy and healthy. Umbilical blood collected at birth. Blood
discarded later when testing reveals this child is not a tissue match / potential
donor for Saskia.
2004
Mum and Dad went to Chicago for IVF / PGD. Twice. Failed both times.
2004
Tried IVF / PGD in London when it became legal for us in the UK. Pregnant.
2005
Collected blood from umbilical cord at Imogen's birth and stem cells
cryogenically stored.
2006-07
BMT work-up. Many tests to make sure Saskia is suitable and healthy enough
for a transplant.
March 2007
After Saskia became eligible for the transplant having passed many organ and
blood tests, she had an operation (general anaesthetic) to have a Hickman Line
inserted.
Appendix: Overview of Saskia’s life with DBA
25th March
Saskia admitted to hospital and put into an isolation room. The room is kept at a
pressure slightly higher than normal as clean air is pumped in continuously. People
entering and leaving the room required to adhere to a strict protocol to minimise
infection risk. Saskia given too many drugs to mention, the most notable of which are
several "chemotherapy" drugs, the purpose of which is to kill off Saskia's bone marrow.
The principal function of bone marrow is to make red blood cells (used to transport
oxygen round the body), white blood cells (used to fight infections) and platelets (used
to help the blood clot).
4th April
Known as "Day Zero". The transplant day. Imogen has operation to take out some of her
bone morrow (this grows back very quickly afterwards). This, together with the stem
cells collected from the umbilical cord when Imogen was born in 2005, is given
intravenously to Saskia. This is not an "operation" as such but a procedure similar in
routine to the 50 or so blood transfusions she has had to date. For the next few weeks
loads more drugs, seemingly 24 hours by Hickman Line, nasal tube and orally. Drugs to
combat the side effects of drugs. Drugs to combat the side effects of those drugs. And
again. No joke. Saskia has side effects, the most obvious being all her hair falling out,
being sick lots and feeling very sick. During the time since admission a family member
was in the room with Saskia 24-hours a day.
2.5 weeks later . . .
Tests of Saskia's neutrophil count indicate that she may be starting to get the
emergence of a new, though very weak immune system. Start taking short trips outside
the hospital to big open spaces since Saskia is doing so well. Moved out of big isolation
room to a smaller one getting ready for going home.
A few days later . . .
Overnight home visit (we live a short walk from the hospital, so very handy). Same the
next night.
Appendix: Overview of Saskia’s life with DBA
And in Late April . . .
•Saskia is Discharged from hospital! We're told this is unusually soon after admission and that
Saskia appears to have done really so far. Not able to tell what's going on in her bone marrow
yet. It's too early to tell how successful the process has been in killing off her old bone marrow
or whether the new bone marrow is producing red blood cells or platelets.
•On 5 drugs, which is a relatively low number at this early post-discharge stage. Their purpose
is: to help prevent infection by bacteria, viruses and fungi; to help prevent graft-v-host disease;
and to reduce blood pressure. Getting Saskia to take these medicines is a real challenge.
•Still severely immuno-deficient and at risk to infection.
•Attending hospital 2-3 times a week for blood tests, check-ups and blood transfusions.
•Saskia able to see friends one-on-one, and allowed to go out to wide open spaces or places with
few people.
•Saskia back to a less controlled diet, though some restrictions still in place.
•Needs to wear sun-block outside since the process has left her skin very sensitive to the sun
•Any infection could easily put her back in hospital, and we're told to "expect" readmission some
time in the next 12 months for some setback or other.
•Saskia is bald and beautiful.
Appendix: Overview of Saskia’s life with DBA
Early/mid May After going in for a routine blood transfusion, Saskia is readmitted (first time)
for observation and an extra intravenous antibiotic. She seems OK on whole but
has been prone to occasional severe shivers which may indicate infection.
Neutrophil count still going up. Platelet count seems holding at an encouraging
level, but early days. Another blood transfusion. Certainly not making many red
blood cells at the moment, which after all is the whole point. Stops taking the
drug which controls blood pressure. She is discharged after 2 nights. No
infections detected during this second stay in hospital, but doctors still extra
wary. Saskia still has that cough. No shivers for a past few days.
Late May
Saskia seems very well. She is at home but visiting the hospital 2-3 times a week.
She has met up with a few friends for one-on-one play dates. Her home schooling
has started: 5 hours a week is not a lot but hopefully it will keep her up to speed
with her peers. There have been some minor discipline issues as would be
expected from a child who, for a few months, has been spoilt for attention, been
highly controlled but had no routine. The daily grind to take the many medicines
is getting slightly easier but still a challenge.
Later May
Results of first "chimerism" test come back to reveal how much Saskia's old bone
marrow (which we hope to have killed) is still working and how much her new bone
marrow is working. The test says that the bone marrow at work is at least 97%
Imogen's - the test doesn't go higher than 97%. Saskia is taking her medicines
better although we are having difficulty maintaining her cyclosporin levels (that's
the one that protects against Graft Vs Host Disease). We still go in to hospital 2
- 3 times a week. No more blood transfusions. Hope to see first evidence of red
cell production soon.
