AB OBJECTIVE: To investigate the HIV-1 V3 sequence diversity in the former
Soviet Union in 30 subjects infected with HIV-1 via different modes of
transmission. PATIENTS: A cohort of children infected after exposure to
nonsterile needles during the epidemic in 1988-1989 in southern Russia
(Elista, n = 12 and Rostov-on-Don, n = 10), and eight HIV-seropositive
subjects from Belarus (Minsk), infected via sexual (n = 7) and
parenteral (n = 1) infection. METHODS: The HIV-1 V3 encoding region was
amplified by nested polymerase chain reaction on DNA of primary
peripheral blood mononuclear cells collected from the study subjects and
then cloned and sequenced. RESULTS: The alignment of 127 V3 sequences
from 22 patients in the cohort group demonstrated common consensus
sequences in both the Elista and Rostov samples. The average means of
interperson variation were 5.9 and 6.6% in Elista and Rostov subjects,
respectively, and comparable to the mean intraperson variation. The
average mean interperson variation between nucleotide sequences of HIV
patients infected through sexual transmission was considerably higher
(14.9%). CONCLUSION: V3 sequence analysis confirms the epidemiologic
data which support the transmission of HIV-1 in children from a single
source, and suggests the infection of a mother from her parenterally
infected child. Furthermore, the genetic variability of HIV-1 V3 in the
noncohort group was particularly divergent indicating the heterogeneity
of the virus circulating in the former Soviet Union.
