Compromise of Second-Line Antiretroviral Therapy Due to High Rates of Human Immunodeficiency Virus Drug Resistance in Mozambican Treatment-Experienced Children With Virologic Failure

Background: Virologic failure (VF) is highly prevalent in sub-Saharan African children on antiretroviral therapy (ART) and is often associated with human immunodeficiency virus drug resistance (DR). Most children still lack access to routine viral load (VL) monitoring for early identification of treatmen...

HIV drug resistance patterns in pregnant women using next generation sequence in Mozambique

PLos ONE; 13 (5), 2018
Background: Few data on HIV resistance in pregnancy are available from Mozambique, one of the countries with the highest HIV toll worldwide. Understanding the patterns of HIV drug resistance in pregnant women might help in tailoring optimal regimens for prevention of mother to child transmission of HIV (...

Determinants of virological failure and antiretroviral drug resistance in Mozambique

J. antimicrob. chemother; 70 (9), 2015
Objectives: The objective of this study was to inform public health actions to limit first-line ART failure and HIV drug resistance in Mozambique. Methods: This was a cross-sectional study. HIV-1-infected adults on first-line ART for at least 1 year attending routine visits in the Manhiça District Hospi...

Trends in Prevalence of HIV-1 Drug Resistance in a Public Clinic in Maputo, Mozambique

PLos ONE; 10 (7), 2015
Background: An observational study was conducted in Maputo, Mozambique, to investigate trends in prevalence of HIV drug resistance (HIVDR) in antiretroviral (ART) naïve subjects initiating highly active antiretroviral treatment (HAART). Methodology/principal findings: To evaluate the pattern of drug res...

Genetic analysis and natural polymorphisms in HIV-1 gp41 isolates from Maputo City, Mozambique

AIDS res. hum. retrovir; 30 (6), 2014
Enfuvirtide was the first fusion inhibitor approved by the Food and Drug Administration (FDA) in 2003 for HIV-1 infection in treatment-experienced patient. It is the first approved antiviral agent to attack the HIV life cycle in its early stages. For HIV fusion to occur, the HR1 and HR2 domains in the gp...

Genetic diversity and naturally polymorphisms in HIV type 1 integrase isolates from Maputo, Mozambique: implications for integrase inhibitors

HIV proviral DNA integration into the host chromosome is carried out by integrase becoming an important target antiretroviral therapy. Raltegravir was the first integrase inhibitor approved for use in HIV therapy and elvitegravir is in the late phase of clinical development; both show good results in mon...

Molecular Epidemiology and Trends in HIV-1 Transmitted Drug Resistance in Mozambique 1999–2018

Viruses; 14 (9), 1992
HIV drug resistance (HIVDR) can become a public health concern, especially in low- and middle-income countries where genotypic testing for people initiating antiretroviral therapy (ART) is not available. For first-line regimens to remain effective, levels of transmitted drug resistance (TDR) need to be m...
