BACKGROUND This systematic review aimed to assess the safety and efficacy of antiretroviral options for postexposure prophylaxis (PEP). Recognizing the limited data on the safety and efficacy of antiretroviral drugs for PEP in children, this review was extended to include consideration of data on the use of antiretroviral drugs for treatment of infants and children living with human immunodefic...

Maternal-fetal HIV-1 transmission can be prevented by administration of AZT, alone or in combination with other antiretroviral drugs to pregnant HIV-1-infected women and their newborns. In spite of the benefits deriving from this life-saving prophylactic therapy, there is still considerable uncertainty on the potential long-term adverse effects of antiretroviral drugs on exposed children. Clini...

Study Finds Antiretroviral Drugs May Prevent HIV Infection A study involving monkeys found that the use of 2 antiretroviral drugs, emtricitabine (FTC) and tenofovir, prevented transmission of a primate version of HIV (Berman J. Voice of America. February 5, 2008). Lead researcher Walid Heneine of the CDC and colleagues injected macaques with single daily doses of FTC and then exposed them once ...

INTRODUCTION Assessing virological response of four-drugs antiretroviral regimen that include raltegravir (RAL) in naïve patients with high viral load (>500,000 copies/mL) selected from a multicentre Italian database. METHODS Naïve patients with HIV RNA>500,000 copies/mL, who began standard antiretroviral regimens either based on non-nucleoside reverse transcriptase inhibitors (NNRTI) or boos...

The risks and benefits of stopping antiretroviral therapy in patients admitted to the ICU are largely unmeasured. In many cases therapy has to be stopped, as parenteral preparations are unavailable for all but one of the antiretroviral agents. Stopping treatment suddenly may be associated with increased risk of resistance because of the long half-life of some of the drugs, and also the risk of ...

Simian immunodeficiency virus (SIV) infection in macaques is so far the best animal model for human immunodeficiency virus type 1 (HIV-1) studies, but suppressing viral replication in infected animals remains challenging. Using a novel single-round infectivity assay, we quantitated the antiviral activities of antiretroviral drugs against SIV. Our results emphasize the importance of the dose-res...

Two antiretroviral medicines recently came on the scene for people starting HIV treatment for the first time: Rilpivirine (brand name Edurant) won marketing approval in May, and the following August saw approval of Complera, a single-pill once-daily regimen that joins rilpivirine with two other drugs. This article explains the science behind rilpivirine and Complera and how these drugs measure ...

HIV-salivary gland associated disease is a well accepted concept in the HIV-related literature. Parotid swellings, especially in its cystic benign lymphoepithelial form, have been largely reported. Oral mucoceles (ranulas) were also associated with HIV in some publications. The exact nature of this link between mucoceles and HIV is still to be clarified. The mainstream treatment of most of paro...

Combivir is a fixed dose combination tablet of two antiretroviral drugs; zidovudine and lamivudine, used in the treatment of HIV-1 infection. AZT was the first antiretroviral used in clinical trials and the addition of lamivudine improved its effectiveness. With the introduction of highly active antiretroviral therapy in the form of a combination of three drugs including two nucleoside analogue...

In the early years of the highly active antiretroviral therapy (HAART) era, HIV with resistance to two or more agents in different antiretroviral classes posed a significant clinical challenge. Multidrug-resistant (MDR) HIV was an important cause of treatment failure, morbidity, and mortality. Treatment options at the time were limited; multiple drug regimens with or without enfuvirtide were us...
