So, as it turns out, there are a couple reasons why the doctors aren’t as “excited” as we are at the rising ANC numbers.

From our perspective, we assumed going from 0 ANC to 400 ANC (today’s reading), meant that the bone marrow cells must have taken root and were growing and producing white blood cells and neutrophils.

But this isn’t quite true.  At least, it isn’t the only scenario!

First… It is possible the body’s “old” bone marrow is the one growing and producing the ANC we are seeing.  In which case, we’ll get to a number somewhere between 400 and 600, and it won’t go any higher.  We’re looking forward to ANC counts well above 1000, and maybe approaching 1500 to 2000 (on a regular basis).

Second… We assumed the new marrow must be in and growing, and that the risk of rejection had past.  But not necessarily true again. Bone marrow rejection can occur many months after it has been given. A sensitive DNA test known as the chimera test will be done at the 30 day mark to see if the transplanted bone marrow has taken root, and is in fact producing it’s own blood cells.

Just when you think you understand this process – it gets more complicated!

Clark got some time with Grandmom today, while Connor was able to spend time with Mom and Dad.  We were very lucky to be able to both be out of the hospital at the same time, and spend time with Connor.

Beth started by walking Connor through Golden Gate Park, and when Dad caught up, the three of us went to the California Academy of Science together.  The Academy of Science is just down the road from UCSF, and we can walk there in literally 10 minutes.  While the entire visit was under 2 hours, it felt like a whole day of fun.

This was my first visit, so I have to take a second to note how amazing and awesome the Cal Academy of Science is.  It is a zoo, rain forest, museum, aquarium and planetarium – all wrapped into one building!  On top of this, they have a ton of educational presentations and special events.  If you can’t learn something new every time you walk into this building, then you don’t have a pulse.

On this particular visit, we spent time downstairs in the aquarium side of the building.  They literally have multiple walls of fish, lit up with UV.  The fish look amazing.  Connor’s eyes were so wide, I was worried they might fall out of his head.

Upstairs, they have a swamp exhibit where we got a chance to see an alligator up close.  But not any alligator, an albino alligator.  Yes, it is real.  And yes, it is white.  Double wow.

Another full day today…

Clark was entertained by the speech therapist and the physical therapist! The speech therapist helped reinforce sign language with play. Using the sign while saying the word gives Clark the option to sign if he doesn’t know how to say it. With time, he will naturally start saying the words instead of signing. We had lots of success with signing with Connor, but Clark appears to be stronger in his comprehension, which has led him to require signing less.  But now that he is trying to communicate back to us, signing is becoming very important to allow him to “talk” to us.

Physical therapy is working on having Clark walk around, squat, balance and bend over. All of which Clark seems to be thriving in. Any excuse to get out of the crib and do something, looks to be of great enjoyment to Clark!

I’m sure you are all impatiently waiting to hear about Clark’s ANC (at least I was)…so I won’t keep you any longer. Today Clark had an ANC of 370! Much higher than Clark’s 140 yesterday…..but, this is still nothing to get excited about, yet. With most patients on the recovery side of a BMT, there doesn’t seem to be a common trend when it comes to their ANC rising. Some kids numbers increase strong and steady, some take a while to get going, while others tend to fluctuate or plateau before reaching 500.

Having an ANC of 500 or greater, helps reduce Clark’s risk of infection. A “normal” ANC is 1500 to 8000/mm3, so we still need to be extremely careful to prevent Clark from getting sick. This is one of the reasons why Clark will still be in isolation for 4-6 months after we leave the hospital.

500 to 1500 is considered the ‘safe” zone. Meaning Clark is still prone to infection, but his body is able to still fight back. There are some perks to Clark’s ANC reaching 500. Such as, Connor will finally be able to visit in the room! Homemade food can be brought in for Clark and we can eat in the hospital room! Clark will also be able to walk around the BMT unit with a mask on! All exciting bouts of freedom which all of us will enjoy.

We had a little surprise today. When Clark’s numbers from his daily blood tests showed up, he had a number greater than zero for his ANC (absolute neutrophil count).  ANC is effectively a number that is calculated based on white blood count (WBC) times neutrophils.  ANC represents the virus fighting power in Clark’s blood.

Needless to say, those cells can’t be transfused, so they only come from one place… Clark’s bone marrow!! Today, Clark’s ANC was 140, up from 0 just a couple of days ago.

Is this engraftment? Technically, no.  The doctors consider it engraftment once Clark’s ANC  reaches 500 for 3 consecutive days.  But is this a good sign? Absolutely YES!  The ANC will continue to fluctuate as we go forward, we just need to see an upward trend over multiple days.  If tomorrow Clark is only at 50, that is fine and is still completely normal.

We had another milestone today; Clark started Cellcept orally! He had been taking it through IV, but they decided to switch him over based on his great progress. Most kids start switching to oral meds a bit later in the process,  due to mucositis or nausea, which lead to emesis. Clark has had a few bouts of emesis, but nothing serious enough to prevent him from taking oral medication.

Clark also had a visit from the speech therapist (ST) today. Clark is now 21 months old, but isn’t saying any words. We thought it might be a good idea to see a ST to evaluate Clark, and to learn if there are ways we can help him out.  Personally, I wasn’t too concerned since Connor was about 24 months when he decided to start speaking. But, since we are here, and the ST was available, I thought this might be a good time for an evaluation.

TIL a ST does a lot more than teach someone how to speak, they find out WHY they aren’t speaking. For example, if Clark was deaf, he would have more difficulty learning to speak than others. There can also be physical ailments such as a cleft tongue or a voice box that isn’t fully developed. Or there is the possibility of a mental disability that can hinder speech.

Thankfully, in Clark’s case, it just seems to be a slight delay in speech, unrelated to a more serious problem. He does not have any hearing loss. He can make sounds, proving that it isn’t a physical problem, and he fully comprehends what we are saying. I was given some tasks to preform for a few months, or until Clark starts speaking. We will continue to teach him names of body parts, learn animal names (from looking at pictures) and make sounds together. We can make animal sounds or have him copy simple sounds that I make. All in all, this feels more like a game instead of work. :)

Yesterday, Clark’s red blood cell (RBC) count was 8.0. We were expecting to give him a RBC transfusion today, but surprisingly his RBC count was 8.3 today! Even though this may look like engraftment, it most likely isn’t since RBC are one of the last blood cells to take hold. What most likely happened, is the small sample of blood that was taken yesterday just happened to have slightly less RBC’s than today’s. Nothing more. Don’t be discouraged though. In my mind, the less transfusions he has, the better.

Clark is still looking and feeling great! Today was slightly less boring than normal, since he had a small episode of emesis this afternoon. Oddly, immediately after we changed his sheets and cleaned up, Clark immediately asked to eat!

Clark was also visited by the physical therapist, book fairy and the music man today! He even learned a few cords on the guitar!

Happy Labour Day!

Patrick, Clark and I spent the day together.  While Patrick and I were talking today, we did a quick calculation.  Including our first 2 surgeries to fix Clark’s mysterious bacterial infection and put in the 2 lumen broviac, as well as the BMT, we have been in hospitals for almost 35 consecutive days!!  Wow, it has been a long time.  Lots of ground covered, but still lots to go!

We are now in the “zone” for engraftment.  There are no expectations for how soon we might see the new bone marrow take root, but somewhere around 14 days, give or take, we expect to see Clark’s neutrophils and ANC rise.  Today was the start of the “earliest” we could expect to see signs.

Once we see growth we move into the next phase, called “Isolation”.  Isolation starts at the hospital, but continues at home for months after we leave.  More on this in the coming weeks – but think of it like “house arrest” with the family. Ha, ha…

We have to give Clark a special clorahexadine bath every day, to ensure we kill any fungus or bacteria that might be growing on his skin.  Clark has decided he likes to wash his truck while I wash him.   That truck is so shiny and clean!

Today was another wonderful “boring” day. Clark is in a great mood. Flirting with the nurses and insisting the doctor listen to his knees instead of his heart with the stethoscope.

There is a  psychiatric ward a floor or 2 below us.  They have a kind of outdoor “compound”, enclosed with high walls and barb wire.  Our guess is that their stay isn’t 100% voluntary.  We are still trying to figure out what type of behavior the patients exhibit to be admitted (more on this as we find out).

Their “rooftop patio” is equipped with a basketball hoop, badminton net and some lounge chairs. We try to align Clark’s “window time” to see the psych patients playing. Sometimes they look like they are in a medicated lull, but today they were more lively and we had fun watching them play! There was even a patient playing guitar. Too bad our windows don’t open, because it would have been nice to listen.
