AB OBJECTIVE: To investigate the prevalence of blood-borne viruses such as
HIV, HCV and HBV among IVDU in Japan, where little is known about the
present situation of IVDU. SUBJECTS AND METHODS: From June to December
1993, serum samples were collected from 47 IVDU (mean age +/- SD: 39.4
+/- 13.0) and 98 alcoholics (mean age +/- SD: 50.6 +/- 10.7) in
Hiroshima, Japan, and examined for the markers for virus infection.
HCV-RNA was assayed by reverse transcriptase-polymerase chain reaction
(RT-PCR) using primers deduced from a 5'-noncoding region of HCV genome.
The env C2-V3 region of the HIV-1 genome was directly sequenced after
being amplified by PCR. All tests were performed with the informed
consent of the subjects. RESULTS AND DISCUSSION: 1) The prevalence of
HCV-antibody (-Ab) and/or HCV-RNA was significantly higher in IVDU than
alcoholics (74.5% vs. 20.4%, P < 0.001). In contrast, the prevalence of
HBs- and/or HBc-Ab showed no significant difference between the two
groups (57.4% vs. 66.3%). This may be due to the fact that HCV infection
becomes persistent at a high rate even in adults unlike HBV infection.
2) HIV-1 infection was found in one case (2.1%) of IVDU in Hiroshima,
Japan. The genetic analysis indicated that the proviral DNA belongs to
subtype B. Careful follow-up of this group is needed.
