OBJECTIVE There are conflicting reports of adverse HIV-associated alterations in white matter integrity as measured by diffusion tensor imaging (DTI). We sought to address these conflicting reports by assessing, on a voxel-by-voxel basis, HIV-associated regional changes in radiologically defined normal-appearing white matter (NAWM) integrity using(More)
The safety and antiviral activity of lopinavir (Lpv), a protease inhibitor (PI) coformulated with ritonavir (Rtv) to enhance its pharmacokinetic properties, were evaluated in 70 patients with plasma human immunodeficiency virus type 1 (HIV-1) RNA levels of 1000-100,000 copies/mL on a first PI-containing regimen. Patients were randomized to substitute only(More)
HIV is associated with increased risk for depression. Normal appearing white matter (NAWM) fractional anisotropy in 15 HIV-seropositive (HIV+) adults with depressive symptoms was compared to 15 HIV+ adults without depressive symptoms. HIV+ adults with depressive symptoms showed increased NAWM fractional anisotropy within the left thalamus, the temporal, and(More)
Differences in the pattern of neuropsychological dysfunction associated with Alzheimer's disease (AD) and vascular dementia (VaD) were examined using the Dementia Rating Scale (DRS). We examined three groups of patients: (1) Patients with AD; (2) patients with single stroke (CVA); and (3) patients with multiple cerebral infarctions (MI). Comparisons of(More)
BACKGROUND In the HAART era, the incidence of HIV-associated non-Hodgkin lymphoma (NHL) is decreasing. We describe cases of NHL among patients with multi-class antiretroviral resistance diagnosed rapidly after initiating newer-class antiretrovirals, and examine the immunologic and virologic factors associated with potential IRIS-mediated NHL. METHODS(More)
The development and widespread clinical use of coformulated abacavir/lamivudine/zidovudine (ABC/3TC/ZDV) as Trizivir represented an important advance in the management of HIV-infected patients, especially those with adherence challenges. With a low pill burden, no food restrictions, limited drug-drug interactions, and a favorable resistance profile,(More)
Protease inhibitors (PIs) block HIV-1 maturation into an infectious virus particle by inhibiting the protease processing of gag and gag-pol precursor proteins. We have used a simple anti-HIV-1 p24 Western blot to monitor the processing of p55gag precursor into the mature p24 capsid immediately following the first dosage of a PI-containing treatment regimen.(More)
The findings of studies that use psychoneuroimmunological frameworks can help nurses evaluate and treat patients' psychological and physical responses to infection with the human immunodeficiency virus (HIV). One response to HIV infection, acquired immunodeficiency syndrome (AIDS) dementia complex (ADC), may occur at any stage of the infection and is(More)
Neuropsychological impairment has been reported to occur in persons at all stages of infection with the human immunodeficiency virus (HIV). However, the findings of studies to characterize the incidence and pattern of impairment have been limited by inconsistent definitions of impairment and the failure to control for confounding variables, such as(More)
