OBJECTIVES To estimate the economic impact of (1) treating pregnant women who are human immunodeficiency virus (HIV)-positive with zidovudine and (2) voluntary screening programs for pregnant women for HIV infection and offering treatment with zidovudine to those found to be HIV-positive. MAIN OUTCOME MEASURES Number of cases of pediatric HIV infection and costs of screening, zidovudine treat...
BACKGROUND Intrapartum single-dose (SD) nevirapine (NVP) reduces perinatal transmission of human immunodeficiency virus (HIV) infection but selects for NVP-resistant virus, which compromises subsequent NVP-based therapy. A 1-week "tail" of lamivudine and zidovudine after SD-NVP decreases the risk of resistance. We hypothesized that increasing the duration or potency of the tail would further re...
In the fall of 2014, an international news agency reported that patients suffering from Ebola virus disease (EVD) in Liberia were treated successfully with lamivudine, an antiviral drug used to treat human immunodeficiency virus-1 and hepatitis B virus infections. According to the report, 13 out of 15 patients treated with lamivudine survived and were declared free from Ebola virus disease. In ...
We measured zidovudine concentrations in blood, muscle, and brain extracellular fluid (ECF) by microdialysis and in serum ultrafiltrate and cerebrospinal fluid (CSF) samples during a continuous intravenous infusion (15 mg/kg/h) and after bolus dosing (50-80 mg/kg over 15 min) in nonhuman primates to determine whether CSF drug penetration is a valid surrogate for blood-brain barrier penetration....
BACKGROUND The AIDS Clinical Trials Group protocol 076 zidovudine prophylaxis regimen for HIV-1-infected pregnant women and their babies has been associated with a significant decrease in vertical HIV-1 transmission in non-breastfeeding women in developed countries. We compared the safety and efficacy of short-course nevirapine or zidovudine during labour and the first week of life. METHODS F...
BACKGROUND The magnitude of infant antiretroviral (ARV) exposure from breast milk is unknown. METHODS We measured concentrations of nevirapine, lamivudine, and zidovudine in serum and whole breast milk from human immunodeficiency virus type 1 (HIV-1)-infected women in Botswana receiving ARV treatment and serum from their uninfected, breast-feeding infants. RESULTS Twenty mother-infant pairs...
BACKGROUND The World Health Organization Antiretroviral Treatment Guidelines recommend phasing-out stavudine because of its risk of long-term toxicity. There are two mutational pathways of stavudine resistance with different implications for zidovudine and tenofovir cross-resistance, the primary candidates for replacing stavudine. However, because resistance testing is rarely available in resou...
Background Lack of viral load monitoring of ART is known to be associated with slower switch from a failing regimen and thereby higher prevalence of MDR HIV-1. Many countries have continued to use thymidine analogue drugs despite recommendations to use tenofovir in combination with a cytosine analogue and NNRTI as first-line ART. The effect of accumulated thymidine analogue mutations (TAMs) on ...
Background & Aims: Allergic reaction is a common side effect of Efavirenz and drug replacement may not be an option to physicians. Here, a successful drug desensitization experiment on an 8-year-old female child over a period of 9 days is reported. Case presentation: The patient was an 8-year old female child with HIV in Kerman, Iran who had been received oral efavirenz together with lamivudine...
