Negative-strand HCV RNA was not detected in bone marrow cells of patients with HCV infection.
To determine whether hepatitis C virus (HCV) replicates in bone marrow, we investigated positive- and negative-strand HCV RNA in bone marrow cells and fluids, and sera from patients with HCV infection. The study population consisted of 15 patients positive for antibodies to HCV (anti-HCV). Positive- and negative-strands HCV RNA were detected using highly strand-specific rTth reverse transcription-polymerase chain reaction (rTth RT-PCR) followed by Southern blotting analysis. Positive-strand HCV RNA was detected in 12 (80%) serum samples, in 13 (86.7%) bone marrow fluid specimens, and in 6 (40.0%) bone marrow cell samples. Negative-strand HCV RNA was detected in 9 (60.0%) serum samples, 11 (91.7%) fluid specimens, while it was not detected in bone marrow cells. The absence of negative-strand HCV RNA in bone marrow cells suggested that HCV does not replicate in these cells. Negative-strand HCV RNA detected in serum and bone marrow fluid samples may have been due to contamination with circulating HCV RNA from hepatocytes.
