Viral Dynamics of Acute HIV-1 Infection

Viral dynamics were intensively investigated in eight patients with acute HIV infection to define the earliest rates of change in plasma HIV RNA before and after the start of antiretroviral therapy. We report the first estimates of the basic reproductive number (R(0)), the number of cells infected by the progeny of an infected cell during its lifetime when target cells are not depleted. The mea...

Hiv-1/hcv Co-infection: Immunity and Viral Dynamics

Herpes simplex virus type 2 infection does not influence viral dynamics during early HIV-1 infection.

OBJECTIVE We sought to compare baseline and longitudinal plasma HIV-1 loads between herpes simplex virus type 2 (HSV-2)-seropositive and -seronegative individuals who are enrolled in a primary HIV-1 infection cohort in San Diego, California. DESIGN The study was a retrospective cohort analysis. METHODS We categorized antiretroviral-naive subjects on the basis of HSV-2 serostatus at baseline...

T cell dynamics in HIV-1 infection.

In the absence of antiretroviral treatment, HIV-1 establishes a chronic, progressive infection of the human immune system that invariably, over the course of years, leads to its destruction and fatal immunodeficiency. Paradoxically, while viral replication is extensive throughout the course of infection, deterioration of conventional measures of immunity is slow, including the characteristic lo...
