Wake up the echoes cheering her name,

Thus begins the chorus of the Notre Dame Fight Song, arguably one of the best known college anthems in the US. It's melody and message are a source of joy and encouragement to ND students and alumni alike.
I awoke about 4:00 am today. I had blood drawn for lab tests around midnight, so I decided to check out the results. They are recorded above, but there is another statistic that I don't generally track, and that is white blood cell (WBC) count. Why do I not track this one? Perhaps, it is simply because I was encouraged to keep an eye on Hemoglobin, platelets and ANC (absolute neutrophil count) from day one after my diagnosis of acute myeloid leukemia (AML).
Neutrophils are WBCs, but there are other WBCs as well, including lymphocytes, monocytes, and eosinophils among others. These various kinds of WBCs each have different functions, but ANC is the best surrogate for tracking immunity, which is very important to AML patients. It essentially tells us when certain medications are required to support the immune system and when they are not. It also gives us guidelines for when we can mingle with other people with relative safety.
Following chemotherapy, which I have had dozens of times, the WBC counts are greatly diminished. As the marrow recovers from the chemotherapy, it begins to produce more WBCs, but the cells are undifferentiated, in other words they need to mature into neutrophils, and lymphocytes and so on. So, for a stretch of time the WBCs can be counted, but until they reach a certain level, it is impossible to differentiate the various types of WBCs, because they are essentially stem cells in need of maturation. And that's where I am at this moment in time.
Prior to bone marrow transplant (BMT), chemotherapy and radiation are used to kill off the patient's (host's) leukemia cells as well as the host bone marrow cells, Following BMT, the donor stem cells, along with some immune cells from the donor, begin to destroy any leukemia cells as well as any remaining host marrow cells. As the donor cells take over they must begin producing new bone marrow cells, which in turn begin producing blood cells, including red cells (RBCs), WBCs, and platelets.
During this transition time between host and donor marrow cells, the patient is extremely vulnerable to infection, which is compensated for by the use of anti-microbial drugs. The WBC count goes essentially to zero. The RBC and platelet counts must be supported by blood transfusions, and then as the donor cells mature and begin producing blood cells, the blood counts begin to rise. When the blood counts begin to rise, it is a sign that the new marrow cells are maturing and beginning to do their job.
The Box Score above shows that my RBCs (Hemoglobin) and platelets are rising. This is the first day in several that I have not needed a transfusion. What you don't see in the Box Score is that the WBC count is rising as well. There has been a rise in WBC count each of the last three days, but the cells are in the stage where they can't be differentiated as to cell type. So, the hope (and the expectation) is that within a couple of days, ANC will begin to appear again in the Box Score, and when ANC reaches 500, I will be discharged. My day nurse yesterday told Jill that I have already surpassed all of the criteria for discharge, except for the ANC.
So, with apologies to Notre Dame (and to the tune of her Fight Song), I offer my own fight song:
Wake up the stem cells growing in me
Send my ANC on high,
That will sure make me one happy guy!
