I love data–it’s fun to hunt down patterns in them. (Yes, “data” is a plural noun–this notice brought to you by the Rear Guard Linguistic Change Resistance League). So, needless to say, I’m obsessed with my blood count spreadsheet:
Green vertical lines are the start of a Vidaza treatment–for me, that’s seven weekdays in a row, every 28 days.
The Vidaza affects my counts in two ways. One, it demethylates my DNA so my body better fights the malignant cells that were making my blood counts fall. (I’m still thinking of this as mentholating my DNA and making it minty fresh, but I’m going to look up the chemistry any day now). The biggest disease symptom I had was lowered platelets–you can see in the lower graph that they were falling steadily before my first Vidaza treatment (the first green line), and overall they are trending back up.
The second way Vidaza affects me is by suppressing my blood counts. This gives me a “nadir,” or low point, after each treatment–in the case of the platelets, you can see that the low point is maybe 2 or 3 weeks into the four-week cycle.
But in the case of white blood cells of various kinds, the top chart, the nadir seems to be about four weeks into my four-week cycle. Every month, the white counts finally start to climb up a bit during the first week of the Vidaza treatment, then head down again as the Vidaza shots continue and the side effect gears up again.
Over Christmas, I got an extra week between cycles 3 and 4, so I could go home and visit my family for the holiday. Right afterwards, my white counts shot up–all the way into the normal range, higher than they’d been since fall of 2011. So, the good news is, that means that the Vidaza is pretty clearly working! That’s the main thing.
As I started to head towards my regularly scheduled nadir, my white counts took a plunge again. To put things into perspective, my white count low point last week was about the same as my high point the month before, so that’s not bad. Here’s the question, though: will I get a big white count peak again next week, due to the Vidaza having kicked in? Or, was the big peak made possible partly or mostly because I’d got a week off?
My counts next week will tell which is stronger, countswise: the primary Vidaza effect or the side effect. Either way, I hope I get the transplant (I’ll find out more when I go see the expert on Monday). But it would be nice to have high counts and the ability to eat salad and so forth for a little bit before I go for the heavy duty stuff.
