Frequency of mutations conferring resistance to nucleoside reverse transcriptase inhibitors in human immunodeficiency virus type 1-infected patients in Korea.

ABSTRACT: A nested PCR and direct sequencing methods were used to define human immunodeficiency virus type 1(HIV-1) reverse transcriptase codons 41 to 219 in DNA from 127 peripheral blood mononuclear cell samples obtained from 35 patients treated with nucleoside reverse transcriptase inhibitors (NRTI). The follow-up period after the initiation of NRTI therapy was 61.8 +/- 31 months (mean and standard deviation). In addition to NRTI therapy, 32 of 35 patients were simultaneously treated with Korean red ginseng. The annual decrease in the CD4(+) T-cell count over 5 years was 13.2/microl. Twenty-eight (80%) of the 35 patients had mutations conferring resistance to NRTI. The frequencies of K70R, T215S/Y/F (i.e., mutation of T at codon 215 to S, Y, or F), D67N/E, K219Q, T69N/S/A, M41L, and L210W mutation
