The absence of CD4+ T cell count recovery despite receipt of virologically suppressive highly active antiretroviral therapy: clinical risk, immunological gaps, and therapeutic options.

Up to 30% of human immunodeficiency virus (HIV)-infected patients who are receiving long-term highly active antiretroviral therapy do not exhibit a marked increase in the CD4(+) T cell count, despite achieving complete suppression of the HIV load. These patients are referred to as "immunological nonresponders." When treating immunological nonresponders, the practicing clinician has several ques...

Poor Immune Reconstitution in HIV-Infected Patients Associates with High Percentage of Regulatory CD4+ T Cells

CD4(+) regulatory T cells (Tregs) are essential for the maintenance of the immune system's equilibrium, by dampening the activation of potential auto-reactive T cells and avoiding excessive immune activation. To correctly perform their function, Tregs must be maintained at the right proportion with respect to effector T cells. Since this equilibrium is frequently disrupted in individuals infect...

Metabolic Abnormalities in HIV-Positive Patients Receiving Highly Active Antiretroviral Therapy

Background and Objective: Dyslipidemia has become a common problem in human immunodeficiency virus (HIV) disease, especially in patients on combination antiretroviral therapy. In this study we aimed to determine the prevalence of dyslipidemia and metabolic abnormalities in 2 groups of HIV infected patients receiving highly activ...

Higher CD27+CD8+ T Cells Percentages during Suppressive Antiretroviral Therapy Predict Greater Subsequent CD4+ T Cell Recovery in Treated HIV Infection

HIV-mediated immune dysfunction may influence CD4(+) T cell recovery during suppressive antiretroviral therapy (ART). We analyzed cellular biomarkers of immunological inflammation, maturation, and senescence in HIV-infected subjects on early suppressive ART. We performed longitudinal analyses of peripheral immunological biomarkers of subjects on suppressive ART (n = 24) from early treatment (me...

Nadir CD4 T cell count as predictor and high CD4 T cell intrinsic apoptosis as final mechanism of poor CD4 T cell recovery in virologically suppressed HIV-infected patients: clinical implications.

BACKGROUND Although antiretroviral therapy improves immune response, some human immunodeficiency virus-infected patients present unsatisfactory CD4 T cell recovery despite achieving viral suppression, resulting in increased morbidity and mortality. METHODS Cross-sectional, case-control study to characterize the mechanism and to identify predictive factors of poor immune response. We included ...
