AB Infection of hematopoietic progenitor cells with the human
cytomegalovirus (HCMV) has been proposed as an explanation for the
cytopenias associated with HCMV-related disease. To test this
hypothesis, CD34+ cells, which include the hematopoietic progenitors, as
well as mature leukocyte populations were purified on a
fluorescence-activated cell sorter and analyzed for HCMV DNA by
polymerase chain reaction (PCR). A total of 33 samples from 31
immunosuppressed as well as immunocompetent HCMV-seropositive
individuals were studied. CD34+ cells were PCR-positive in four of seven
bone marrow aspirates from allogeneic bone marrow transplant recipients,
in three of eight aspirates from patients with acquired immunodeficiency
syndrome, and in the first of two bone marrow samples from an
immunocompetent patient with primary HCMV disease. CD34+ cells purified
from peripheral blood for autologous and allogeneic transplantation were
also analyzed, and 4 of 13 samples were HCMV DNA-positive.
Interestingly, two of the four HCMV-positive samples were from healthy
allogeneic donors. Among the mature leukocyte populations, the monocytes
were most frequently found to be HCMV DNA-positive. No HCMV DNA was
detected in the total bone marrow leukocytes of 13 healthy seropositive
bone marrow donors or in the CD34+ cell fraction of three further
seropositive donors. In conclusion, the data provide strong evidence
that CD34+ hematopoietic progenitor cells can be infected with HCMV in
immunosuppressed patients, while this cell population was not identified
as a major viral reservoir in healthy HCMV-seropositive individuals.
