On day +77, Clark had his regular 4 week check-up. This included a blood draw, bandage change and IViG infusion. Since Clark had his immune system wiped out from Chemo, getting regular infusions of IViG is vital to his health. Intravenous immunoglobulin (IViG) is antibodies collected from the plasma of a healthy person. This product is donated similar to blood. (Thank you donors!) So, if you are able, please consider donating blood, platelets, plasma or bone marrow. Your generosity will literally save someones life!
Other than the fact that Clark gets bored and tired during these long appointments, things went really well. And in this case, we received some really good news! The doctors have decided to test the functionality of Clark’s Lymphocytes early! This is a test we were expecting closer to day 100.
As we’ve talked about in earlier posts, a lymphocyte is a special type of White Blood Cell (WBC) that was killed off by chemo. This is done to prevent GvHD in the early stages of a BMT. Generally when checking the value of Clark’s lymphocytes, we get an ALC (Absolute Lymphocyte Count) which consist of NK cells, T cells and B cells. What we are watching for right now is his T cells. If Clark’s T cells are at least 25% of his ALC and they are functional…. Clark will no longer need to be in isolation!!
We are still waiting for results because the blood will be sent to the Mayo Clinic for the tests.
The way they test Clark’s lymphocyte functionality is pretty cool. Basically, they give his blood (from the sample) an actual infection. Then they watch for days to see how well the T cells destroy the invaders, and how quickly they can react.
Some other exciting news is that Clark is tapering his cyclosporin. Just a few months ago, Clark was taking 0.35mL three times/day. Now he is taking 0.15 twice/day. And by November 28th, he will no longer be taking it! Cyclosporin is an immuno-suppressant. He needs to take this to prevent his new marrow from attacking his old marrow. The slow tapering is to prevent GvHD. So far so good (no signs of GvHD)!
The first sign of GvHD is usually a skin rash. And because of this, we’ve definitely been anxious a couple times over the last couple months. Clark has sensitive skin (runs in the family), and when ever he rubs his face on a shirt, the carpet, or Patrick’s unshaven face… he gets a big blotchy red marks that can last about 30 minutes. So a couple times now we’ve seen bright redness on Clark’s face or arms, freaked out, and then calmed down and had to wait a half hour to make sure it was just from playing. So far, we’ve been lucky and it’s faded. With “real” GvHD, the rash would stay, and possibly continue to worsen.
