Patients receiving optimal care for HIV infection can expect to live about as long as those who are uninfected, according to an updated analysis being published in Annals of Internal Medicine.
Published Studies Related to Reyataz (Atazanavir)
Determination of rifabutin dosing regimen when administered in combination with ritonavir-boosted atazanavir. [2011.09]
OBJECTIVES: Treatment of HIV/tuberculosis (TB) co-infected patients is complex due to drug-drug interactions for these chronic diseases. This study evaluates an intermittent dosing regimen for rifabutin when it is co-administered with ritonavir-boosted atazanavir... CONCLUSIONS: The benefits to HIV/TB co-infected patients receiving rifabutin 150 mg three times weekly or every other day may outweigh the risks of neutropenia observed here in non-HIV-infected subjects, provided that patients on combination therapy will be closely monitored for safety and tolerability.
Peripheral and central fat changes in subjects randomized to abacavir-lamivudine or tenofovir-emtricitabine with atazanavir-ritonavir or efavirenz: ACTG Study A5224s. [2011.07.15]
BACKGROUND: We compare the effect of 4 different antiretroviral regimens on limb and visceral fat... CONCLUSIONS: ABC-3TC- and TDF-FTC-based regimens increased limb and visceral fat at week 96, with a similar prevalence of lipoatrophy. Compared to the EFV group, subjects assigned to ATV-r had a trend towards higher mean percentage increase in VAT. CLINICAL TRIALS REGISTRATION: NCT00118898.
Lipid profiles for nevirapine vs. atazanavir/ritonavir, both combined with tenofovir disoproxil fumarate and emtricitabine over 48 weeks, in treatment-naive HIV-1-infected patients (the ARTEN study). [2011.07]
OBJECTIVES: Dyslipidaemic effects of antiretrovirals (ARVs) may contribute to increased cardiovascular risk (CR) in HIV-1-infected patients. The ARTEN (atazanavir/ritonavir on a background of tenofovir and emtricitabine vs. nevirapine on the same background, in naive HIV-1-infected patients) study compared prospectively ritonavir-boosted atazanavir (ATZ/r) 300 mg/100 mg once daily (qd) with immediate release nevirapine (NVP) 200 mg twice daily or 400 mg qd, each combined with fixed-dose tenofovir 300 mg/emtricitabine 200 mg qd in 569 ARV-naive HIV-1-infected patients. Lipid profiles and CR from baseline to week 48 are reported... CONCLUSIONS: In ARV-naive patients with low CR at the outset, NVP showed a potentially less atherogenic lipid profile compared with ATZ/r. (c) 2011 British HIV Association.
Bone mineral density and fractures in antiretroviral-naive persons randomized to receive abacavir-lamivudine or tenofovir disoproxil fumarate-emtricitabine along with efavirenz or atazanavir-ritonavir: Aids Clinical Trials Group A5224s, a substudy of ACTG A5202. [2011.06.15]
BACKGROUND: Long-term effects of abacavir (ABC)-lamivudine (3TC), compared with tenofovir (TDF)-emtricitabine (FTC) with efavirenz (EFV) or atazanavir plus ritonavir (ATV/r), on bone mineral density (BMD) have not been analyzed... CONCLUSIONS: Compared with ABC-3TC, TDF-FTC-treated participants had significantly greater decreases in spine and hip BMD, whereas ATV/r led to more significant losses in spine, but not hip, BMD than EFV. Clinical Trials Registration. NCT00118898.
Atazanavir plus ritonavir or efavirenz as part of a 3-drug regimen for initial treatment of HIV-1. [2011.04.05]
BACKGROUND: Limited data compare once-daily options for initial therapy for HIV-1. OBJECTIVE: To compare time to virologic failure; first grade-3 or -4 sign, symptom, or laboratory abnormality (safety); and change or discontinuation of regimen (tolerability) for atazanavir plus ritonavir with efavirenz-containing initial therapy for HIV-1... CONCLUSION: Atazanavir plus ritonavir and efavirenz have similar antiviral activity when used with abacavir-lamivudine or tenofovir DF-emtricitabine.
