HIV-1 Continues To Replicate and Evolve in Patients with Natural Control of HIV Infection

Evaluation of clinical course and laboratory findings in HIV/HTLV-1 co-infection compare with HIV mono infection

Background: In the last 10 years, co-infection of human immunodeficiency virus/human T-cell leukemia virus-1 (HIV/HTLV-1) has emerged as a worldwide health problem. These viruses has the same route to infect human but different effects on CD4 positive T-cells. There was controversial results about the influence of co-infection HIV/HTLV-1 pathogenesis. This study compared clinical course and lab...

Response: HIV-2 and Natural Protection Against HIV-1 Infection.

Natural killer cells from HIV-1+ patients produce C-C chemokines and inhibit HIV-1 infection.

Human NK cells have been shown to produce cytokines (e.g., IFN-gamma and TNF-alpha) and the chemokine macrophage inflammatory protein (MIP)-1alpha following stimulation with the combination of two monokines, IL-15 plus IL-12. The C-C chemokines MIP-1alpha, MIP-1beta, and RANTES have been identified as the major soluble macrophage-tropic HIV-1-suppressive factors produced by CD8+ T cells, which ...

Thoracic CT Scan Findings in Patients with HIV/TB co-infection before and after treatment

Background and Aim: Pulmonary tuberculosis (TB) infection is common in patients infected with the Human immunodeficiency virus (HIV). In this study, we evaluated thoracic CT scan findings of HIV/TB co-infection, before and after anti-TB treatment. Materials and Methods: In this retrospective cross-sectional study, pre-and post-treatment thoracic CT scans of patients diagnosed with HIV and defin...

Natural history of HIV-1 infection.

Infection with the human immunodeficiency virus type 1 (HIV-1) results in progressive loss of immune function marked by depletion of the CD4+ T-lymphocytes, leading to opportunistic infections and malignancies characteristic of AIDS. Although both host and viral determinants influence the rate of disease progression, the median time from initial infection to the development of AIDS among untrea...
