Long-term follow-up of patients taking tenofovir DF with low-level HIV-1 viremia and the K65R substitution in HIV-1 RT 总被引:1,自引:0,他引:1
Patients with on-going HIV-1 replication and a K65R mutation in HIV-1 RT were assessed for further development of RT mutations while taking tenofovir disoproxil fumarate and other antiretroviral drugs. K65R was observed in 10 out of 536 treatment-experienced patients entering the study. K65R became undetectable in two patients, and the development of additional resistance mutations was minimal. Over 18 months, no patient developed multinucleoside resistance (Q151M or T69 insertions) and plasma viral loads were stable (median +0.04 log10 copies/ml). 相似文献

The vast majority of HIV-1 infections globally are caused by subtype A or C, although little is known about their drug resistance profiles. We found that HAART-experienced patients infected with subtype A had a lower prevalence of K65R and Y181C than those with subtypes B or C, despite similar exposure to antiretroviral agents that select for these mutations. If confirmed, this information may be important in the planning of antiretroviral regimens in patients infected with HIV-1 subtype A. 相似文献
