Invasive aspergillosis (IA) has been traditionally considered an infection occurring in patients with well established risk factors, such as neutropenia, hematologic malignancies, organ transplantation, or HIV. However there is increasing evidence that apparently immunocompetent patients, such as those with severe liver disease, are also at high risk for(More)
BACKGROUND Adipose tissue alterations (ATAs) are a frequent untoward effect of antiretroviral therapy, the causes of which remain incompletely explained. OBJECTIVES To assess the incidence of ATAs and to identify the associated risk factors in patients infected with human immunodeficiency virus type 1 starting their first-line antiretroviral treatment.

Improvements in HIV-RNA assays have made accurate detection of as few as 2 copies/ml possible. This study objective was the evaluation of ultrasensitive HIV-RNA quantitation (beneath current threshold: 50 copies/ml) in patients receiving different antiretroviral regimens. A cross-sectional, ultrasensitive measurement of HIV-RNA levels (detection limit: 2.5(More)
The HIV Nef protein mediates endocytosis of surface receptors that correlates with disease progression, but the link between this Nef function and HIV pathogenesis is not clear. Here, we report that Nef-mediated activation of membrane trafficking is bidirectional, connecting endocytosis with exocytosis as occurs in activated T cells. Nef expression induced(More)
OBJECTIVES It is still debated if pre-existing minority drug-resistant HIV-1 variants (MVs) affect the virological outcomes of first-line NNRTI-containing ART. METHODS This Europe-wide case-control study included ART-naive subjects infected with drug-susceptible HIV-1 as revealed by population sequencing, who achieved virological suppression on first-line(More)
Oleanolic acid is a triterpenoid which is quite common in nature in the form either of free acid or in triterpenoid saponin glycosides. This study describes the effect of oleanolic acid on the growth of human immunodeficiency virus-1 (HIV-1) in cultures of human peripheral mononuclear cells (PBMC) and of monocyte/macrophages (M/M). Its inhibitory activity(More)
Myelin basic protein (MBP) was measured in cerebrospinal fluid (CSF) of patients with acquired immunodeficiency syndrome (AIDS) dementia complex (ADC) in order to investigate the degree of white matter destruction. Results show that increased CSF levels of MBP were detected in all patients with severe ADC (10/10) and, less often, in subjects with mild (2/7)(More)
