BACKGROUND Adverse drug reactions are a major concern with zidovudine/stavudine treatment regimens. The less toxic tenofovir regimen is an alternative, but is seldom considered due to the higher costs. This study compared adverse drug reactions and other clinical outcomes resulting from the use of these two treatment regimens in India. METHODS Baseline, clinical characteristics and follow-up ...
Zidovudine, the antiretroviral drug used to treat HIV infection, commonly causes adverse effects, such as systemic fever and gastrointestinal alterations. In the present study, the potential role of inosine triphosphate pyrophosphatase (ITPA) gene variant on the incidence of adverse events during antiretroviral therapy (ART) of HIV with zidovudine was discussed. Individuals from Northeastern Br...
Study Purposes. This study examined whether melanonychia was more prevalent in 1) HIV positive individuals compared to HIV negative persons, 2) HIV positives exposed to zidovudine and/or stavudine and 3) those with darker skin pigmentation. Procedures. 267 HIV positive and 273 HIV negative patients were examined for presence or absence of melanonychia and level of skin pigmentation using the Fi...
Zidovudine (3'-azido-2',3'dideoxythymidine) is a drug with proved antihuman immunodeficiency virus (HIV) reverse transcriptase activity. It has been clearly demonstrated that the benefits of zidovudine outweigh the risks of its use."'5 Different adverse effects have been reported for zidovudine, including anaemia, neutropenia, nausea, vomiting, myalgias, abnormalities of liver function, bluish ...
OBJECTIVES Zidovudine and tenofovir are the two main nucleos(t)ide analogs used to prevent mother-to-child transmission of HIV. In vitro, both drugs bind to and integrate into human DNA and inhibit telomerase. The objective of the present study was to assess the genotoxic effects of either zidovudine or tenofovir-based combination therapies on cord blood cells in newborns exposed in utero. DE...
Combination antiretroviral therapy (CART) dramatically decreases mother-to-child HIV-1 transmission (MTCT), but maternal adverse events are not infrequent. A review of 117 locally followed pregnancies revealed 7 grade ≥ 3 AEs possibly related to antiretrovirals, including 2 hematologic, 3 hepatic, and 2 obstetric cholestasis cases. A fetal demise was attributed to obstetric cholestasis, but no ...
Zidovudine treatment preferentially benefits persons with only non-syncytium-inducing (NSI) human immunodeficiency virus type 1 (HIV-1) variants. To understand this differential efficacy, changes in cellular virus load, clonal composition of HIV-1 populations, and development of resistance-conferring reverse transcriptase mutations were studied in 17 persons initiating zidovudine therapy. Zidov...
BACKGROUND The safety and efficacy of adding antiretroviral drugs to standard zidovudine prophylaxis in infants of mothers with human immunodeficiency virus (HIV) infection who did not receive antenatal antiretroviral therapy (ART) because of late identification are unclear. We evaluated three ART regimens in such infants. METHODS Within 48 hours after their birth, we randomly assigned formul...
BACKGROUND It is unclear whether therapy for human immunodeficiency virus type 1 (HIV-1) should be initiated with a four-drug or two sequential three-drug regimens. METHODS In this multicenter trial we compared initial therapy involving four-drug regimens containing efavirenz and nelfinavir in combination with either didanosine and stavudine or zidovudine and lamivudine with therapy involving...
