Abstract: In particular, two mutations (
K70R and
V118I), detectable by LIPA and by sequencing analysis respectively, revealed resistance to
NRTIs in two plasma samples.
Result: As expected, the presence of mutations associated with resistance to non
nucleoside reverse transcriptase inhibitors (
NNRTIs), only revealed by sequencing analysis showed VI 081 (associated with a reduced drug sensitivity to efavirenz plus nevirapine),
V118I (associated with moderate phenotypic lamivudine resistance) and the presence of
K103N (key mutation for all the NNRIs) plus
Y181C (with variable effects on susceptibility to efavirenz, besides resistance to nevirapine).
