Treatment-associated polymorphisms in protease are significantly associated with higher viral load and lower CD4 count in newly diagnosed drug-naive HIV-1 infected patients [PDF]

Retrovirology, 2012
Background The effect of drug resistance transmission on disease progression in the newly infected patient is not well understood. Major drug resistance mutations severely impair viral fitness in a drug free environment, and therefore are expected to ...

Baseline resistance to nucleoside reverse transcriptase inhibitors fails to predict virologic response to combination therapy in children (PACTG 338) [PDF]

AIDS Research and Therapy, 2007
Background The association between baseline drug resistance mutations and subsequent increase in viral failure has not been established for HIV-infected children.

Life cycle synchronization is a viral drug resistance mechanism. [PDF]

PLoS Computational Biology, 2018
Viral infections are one of the major causes of death worldwide, with HIV infection alone resulting in over 1.2 million casualties per year. Antiviral drugs are now being administered for a variety of viral infections, including HIV, hepatitis B and C ...

High viremia and low level of transmitted drug resistance in anti-retroviral therapy-naïve perinatally-infected children and adolescents with HIV-1 subtype C infection [PDF]

BMC Infectious Diseases, 2012
Background High plasma viremia in HIV-1 infection is associated with rapid CD4 cell decline and faster disease progression. Children with HIV infection have high viral loads, particularly in early childhood.

Loss and recovery of genetic diversity in adapting populations of HIV. [PDF]

PLoS Genetics, 2014
The evolution of drug resistance in HIV occurs by the fixation of specific, well-known, drug-resistance mutations, but the underlying population genetic processes are not well understood.

Conquering viral drug resistance: Structural and mechanistic paradigms for antiresistance drug design

Pharmaceutical Science Advances
Viral drug resistance remains a critical challenge in antiviral therapy. This perspective highlights five studies on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), human immunodeficiency virus type 1 (HIV-1), monkeypox virus (MPXV ...

A Compensatory Mutation Provides Resistance to Disparate HIV Fusion Inhibitor Peptides and Enhances Membrane Fusion [PDF]

, 2013
Fusion inhibitors are a class of antiretroviral drugs used to prevent entry of HIV into host cells. Many of the fusion inhibitors being developed, including the drug enfuvirtide, are peptides designed to competitively inhibit the viral fusion protein ...

“I feel drug resistance testing allowed us to make an informed decision”: qualitative insights on the role of HIV drug resistance mutation testing among children and pregnant women living with HIV in western Kenya

BMC Health Services Research, 2023
Background Pregnant women and children living with HIV in Kenya achieve viral suppression (VS) at lower rates than other adults. While many factors contribute to these low rates, the acquisition and development of HIV drug resistance mutations (DRMs) are

HIV-1 resistance profile in plasma and peripheral blood lymphocytes in a group of naive patients [PDF]

Archives of Biological Sciences, 2012
Transmitted HIV-1 drug resistance (TDR) is a persisting problem, even though the prevalence of primary resistance may remain stable or start to decline.

Uptake of antiretroviral treatment and viral suppression among men who have sex with men and transgender women in sub-Saharan Africa in an observational cohort study: HPTN 075

International Journal of Infectious Diseases, 2021
Objectives: HPTN 075 enrolled men who have sex with men (MSM) and transgender women (TGW) in sub-Saharan Africa. Persons in HIV care or on antiretroviral treatment (ART) were not eligible to enroll.
