title: [Prognosis and evaluation of drug therapy by V3 and RT gene analysis of HIV-1].
abstract: We have reported on the investigation of 54 HIV-1 patients concerning the isolation and clinical marker in the preceding paper. We have attempted the analysis of the V3 and RT genes. HIV-1 from a patient who had rapidly taken a turn for the worse had basic amino acid at position 11 (Arg) and lost an acidic amino acid at position 25 (Gln) of V3. This sequence pattern was a distinguished feature of a virus with a rapid-high, syncytium inducing (SI) and T-cell-line tropic phenotype. In contrast, patients with no or mild clinical symptoms had sequences characterized as slow-low, non-synsytium inducing (NSI) and macrophage tropic. We then investigated the appearance of resistant to AZT and ddI. It was shown that the virulent virus obtained drug resistant variants faster than the wild type by analysis of the RT gene. We consider that these data concerning virus isolation and gene analysis are useful for prognosis and strategy for clinical therapy.
