BACKGROUND Despite effective highly active antiretroviral therapy (HAART), some patients infected with HIV have persistently low CD4 cell counts with risk of HIV disease progression. The addition of interleukin-2, a cytokine that stimulates CD4 T lymphocyte helper cells, may benefit patients with discordant responses. METHODS A total of 72 HIV-infected(More)
BACKGROUND Memory cytotoxic T lymphocytes (CTL) should play a key role in controlling HIV infection. The correlations between the breadth and specificities of memory CTL and virus production and disease progression are still unknown, but are of major importance for vaccine strategies. METHODS AND DESIGN One-hundred and forty-eight chronically-infected(More)
Epidemiological validity of early markers of nephrotoxicity currently used in occupational epidemiology has been poorly investigated. The aim of this study was to identify variation factors of these markers, to quantify their intra- and inter-individual variability and to evaluate the consequences of these results on study size and power. A cross-sectional(More)
HIV-specific cytotoxic CD8(+) T-lymphocytes (CTL) appear to be the cornerstone of the immune response to HIV infection. Recent studies show that CTL activity reflects patients' anti-HIV immune status and slows disease progression. However, the dynamics of the diversity of this response also appears as a key parameter for immune control but the dynamics of(More)
The timing of mother-to-child HIV transmission is not directly observable but influences the infected child's viral and immune status in the neonatal period. A hierarchical model was developed in a Bayesian framework to 'back-calculate' the timing of HIV-1 transmission from mother to child from the virological and immunological kinetics in the infected(More)
OBJECTIVES To quantify and identify sources of within- and between-subject variability of microalbumin, N-acetyl-beta-D-glucosaminidase (NAG) and alanine aminopeptidase (AAP), three biomarkers used for early detection of renal injury, and to assess the consequences of this variability for the design and power of epidemiological studies. METHODS Urinary(More)
BACKGROUND Inherited ichthyoses represent a group of rare skin disorders characterized by scaling, hyperkeratosis and inconstant erythema, involving most of the tegument. Epidemiology remains poorly described. This study aims to evaluate the prevalence of inherited ichthyosis (excluding very mild forms) and its different clinical forms in France. METHODS(More)
A large body of research work examined, from both the query side and the user behaviour side, the characteristics of medical and health-related searches. One of the core issues in medical information retrieval is diversity of tasks that lead to diversity of categories of information needs and queries. From the evaluation perspective, another related(More)
OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. Abstract. In information retrieval literature, understanding the users' intents behind the queries is critically important to gain a better insight of how to select relevant results. While many studies investigated how(More)
