Resistance mutations against dolutegravir in HIV integrase impair the emergence of resistance against reverse transcriptase inhibitors.
OBJECTIVE Among 1222 antiretroviral-naive patients who received dolutegravir (DTG) as part of first-line therapy, none has developed resistance against this compound after 48-96 weeks of follow-up. Moreover, only four occurrences of virological failure with resistance mutations have been documented in previously drug-experienced patients who received DTG as a first time integrase inhibitor as a...
متن کاملSevere Thrombocytopenia During Dolutegravir-containing Antiretroviral Therapy
A 56-year-old Japanese man diagnosed with acquired immunodeficiency syndrome, Pneumocystis jirovecii pneumonia and cytomegalovirus infection presented with thrombocytopenia after starting antiretroviral therapy, which included dolutegravir (DTG). Although good control of the human immunodeficiency virus and cytomegalovirus infections was achieved, the patient's thrombocytopenia persisted. The p...
متن کاملWill drug resistance against dolutegravir in initial therapy ever occur?
Dolutegravir (DTG) is a second-generation integrase strand transfer inhibitor (INSTI) and INSTIs are the latest class of potent anti-HIV drugs. Compared to the first generation INSTIs, raltegravir, and elvitegravir, DTG shows a limited cross-resistance profile. More interestingly, clinical resistance mutations to DTG in treatment-naive patents have not been observed to this date. This review su...
متن کاملMutations Located outside the Integrase Gene Can Confer Resistance to HIV-1 Integrase Strand Transfer Inhibitors
Resistance to the integrase strand transfer inhibitors raltegravir and elvitegravir is often due to well-identified mutations in the integrase gene. However, the situation is less clear for patients who fail dolutegravir treatment. Furthermore, most in vitro experiments to select resistance to dolutegravir have resulted in few mutations of the integrase gene. We performed an in vitro dolutegrav...
متن کاملDolutegravir resistance mutation R263K cannot coexist in combination with many classical integrase inhibitor resistance substitutions.
The new integrase strand transfer inhibitor (INSTI) dolutegravir (DTG) displays limited cross-resistance with older drugs of this class and selects for the R263K substitution in treatment-experienced patients. We performed tissue culture selections with DTG, using viruses resistant to older INSTIs and infectivity and resistance assays, and showed that the presence of the E92Q or N155H substitut...
