At a wit's end here...

Husband had a bone marrow biopsy, and I have the results (I am a nurse in the system), but the hematologist is not quick in responding to our calls for explanation.  Once again we get to live thru a stressful weekend of waiting and not knowing what's going on, so I'm hoping I get can get a clue here.  

In a nutshell, he has absolutely no symptoms, but neutrophils have been low (0.1 up to 1.7 in the last ten weeks).  All other counts, tests, are normal.  Biopsy report says "Granulopoiesis adequate and progressive to the band stage, but partially arrested at the band stage."  Bone marrow band neutrophils are 23.0% and segmented neutrophils are 3.0%.  As I said, he's had no problems, viruses, bacterial infections in the past six months that we can think of.

However, about 18 months ago he had a prostate biopsy because his PSA was 4.3.  Results were negative, and PSA has since come down to 1.5, which seems a little odd to me because PSA doesn't typically go down for no reason at all.  He did not receive antibiotic treatment at the time.  So my question is, in lieu of the fact that his ESR is normal, could the neutropenia be caused by some asymptomatic prostate infection from months ago?

Any insight you can give me would be appreciated since this hematologist of ours isn't responding to our calls.  Thanks.
