Significant intra- and interindividual variability has been observed in response to use of pharmacological agents in treatment of HIV infection. Treatment of HIV infection is limited by high rates of adverse drug reactions and development of resistance in a significant proportion of patients as a result of suboptimal drug concentrations. The efficacy of antiretroviral therapy is challenged by t...
background and aims: genotyping assay has been accepted as a guidance in the therapeutic management of human immunodeficiency virus 1 (hiv-1). but, it is not commonly used in our country due to its high running cost. the aim of this study is evaluate an in-house genotyping resistance test (grt) for hiv-1. methods: hiv-1 rna of 20 samples were extracted from plasma and rt nested- pcr was perform...
In The HIV Prevention Trials Network 061 study, 155 human immunodeficiency virus (HIV)-infected men reported no prior HIV diagnosis; 83 of those men had HIV RNA levels of <1000 copies/mL at enrollment. Antiretroviral drug testing revealed that 65 of the 83 (78.3%) men were on antiretroviral treatment. Antiretroviral drug testing can help distinguish between newly diagnosed and previously diagno...
The ability of HIV-1 to evolve resistance to antiretroviral drugs leads to treatment failure. By nucleotide sequencing of HIV-1 subtype B isolates, amino acids responsible for drug resistance have been identified. Less information is available, however, on the extent and distribution of these amino acids in HIV-1 nonsubtype B viruses circulating mainly in developing countries. More HIV-infected...
Replication of drug-resistant human immunodeficiency virus type 1 (HIV-1) in the presence of drug can lead to the failure of antiretroviral drug treatment. Drug failure is associated with the accumulation of drug resistance mutations. Previous studies have shown that 3'-azido-3'-deoxythymidine (AZT), (-)2',3'-dideoxy-3'-thiacytidine (3TC), and AZT-resistant HIV-1 reverse transcriptase (RT) can ...
BACKGROUND As the most populated Persian Gulf country, in Iran, engagement with drug injection and unsafe sex are the main routes of HIV transmission among some drug-dependent women. OBJECTIVES The current study explored the barriers that a group of drug-dependent women reported in accessing and adhering to HIV services in drug use treatment. PATIENTS AND METHODS Qualitative interviews were...
Background and Aim: Children who work or live in the streets are one of the high-risk groups for HIV. The high population of street children and lack of comprehensive intervention programs for them increase their risk for HIV in Iran. This study intended to explore the situation of drug abuse in street children in Tehran, the capital city. Materials and Methods: This paper reports part of a com...
BACKGROUND Injection drug use has been the major route of HIV transmission over the past several years in some countries. The aim of this study was to describe epidemiologic and demographic factors, as well as the risk behavior data in HIV-positive patients referred to a private clinic in Tehran. METHODS A retrospective study was conducted in 2005 based on documents of 150 HIV-infected patien...
Injection drug users represent a major vector of human immunodeficiency virus (HIV) infection in the nation's inner cities, and are an important population for harm reduction treatment interventions to target. However, there has been relatively little research examining the specific contribution of the multiple factors contributing to cognitive functioning among injection drug users that may af...
The high prevalence of HIV infection and drug dependence among prisoners, combined with the sharing of injecting drug equipment, make prisons a high-risk environment for the transmission of HIV. Ultimately, this contributes to HIV epidemics in the communities to which prisoners return on their release. We reviewed the effectiveness of interventions to reduce injecting drug use risk behaviours a...
