Jm. Kindelan et al., Prevalence of primary mutations in human immunodeficiency virus with resistance to nucleoside analogues in naive human immunodeficiency virus-infected patients from Andalucia (Spain), MED CLIN, 115(11), 2000, pp. 423-425
BACKGROUND: TO analyze the frequency of HIV primary mutations to nucleoside
s analogues in Andalusia. PATIENTS AND METHOD: Genotype study (LiPA) of mut
ations in codons M41L, T69D, K70R, L74V, M184V, T215Y/F and RT75G-S was per
formed in 106 HIV-naive patients from 12 Andalusian hospitals, with viral l
oad over 5000 copies of RNA/ml. RESULTS: Reliable results were obtained in
96 patients; 11 of them (11.45%) showed 12 mutations: two in codon 41, four
in codon 70, three in codon 184 and three in codon 215. One patient showed
two mutations (41 and 215). The presence of mutations only was related to
having sex partner and sexual transmission of HIV infection, CONCLUSIONS: a
) The primary mutations to nucleosides in HIV patients from Andalusia was 1
1.45%; b) mainly involved drugs were AZT and 3Tc, and c) mutations regardin
g resistance to ddC, ddl o D4T were not found.
