AIDS-related mycoses: the way forward.

Hide Abstract
The contribution of fungal infections to the morbidity and mortality of HIV-infected individuals is largely unrecognized. A recent meeting highlighted several priorities that need to be urgently addressed, including improved epidemiological surveillance, increased availability of existing diagnostics and drugs, more training in the field of medical mycology, and better funding for research and provision of treatment, particularly in developing countries.

Hide Abstract
Since 2010, World Health Organization (WHO) guidelines discourage using stavudine in first-line regimens due to frequent and severe side effects. This study describes the implementation of this recommendation and trends in usage of antiretroviral therapy combinations in a cohort of HIV-positive patients in rural Tanzania.

Viral hepatitis and rapid diagnostic test based screening for HBsAg in HIV-infected patients in rural Tanzania.
PLoS ONE

Show Abstract
Hide Abstract
Co-infection with hepatitis B virus (HBV) is highly prevalent in people living with HIV in Sub-Saharan Africa. Screening for HBV surface antigen (HBsAg) before initiation of combination antiretroviral therapy (cART) is recommended. However, it is not part of diagnostic routines in HIV programs in many resource-limited countries although patients could benefit from optimized antiretroviral therapy covering both infections. Screening could be facilitated by rapid diagnostic tests for HBsAg. Operating experience with these point of care devices in HIV-positive patients in Sub-Saharan Africa is largely lacking. We determined the prevalence of HBV and Hepatitis C virus (HCV) infection as well as the diagnostic accuracy of the rapid test device Determine HBsAg in an HIV cohort in rural Tanzania.

Alterations in T cell subsets in human immunodeficiency virus-infected adults with co-infections in southern Mozambique.

Hide Abstract
T cell activation and depletion of naive T cells are hallmarks of human immunodeficiency virus (HIV) pathogenesis. This study explored the relationships between certain co-infections (including syphilis, hepatitis B and C, human T cell lymphotrophic viruses I and II [HTLV-I/II], Kaposi sarcoma-associated herpesvirus [KSHV], Plasmodium falciparum malaria, and tuberculosis), and levels of activated CD8 and CD4 T cell subsets as well as naive and memory CD4 T cells in HIV-infected adults in a rural area of southern Mozambique. We found that syphilis infection and to a lesser extent HTLV-I/II seropositivity were independently associated with higher CD8 T cell activation (CD8+ CD38+ HLA-DR+) whereas only syphilis was associated with higher CD4 T cell activation. Furthermore, KSHV and HTLV-I/II seropositivities were independently associated with a lower percentage of naive CD4 T cells (CD4+ CD45RA+ CD62L+). These results highlight the importance of screening and prompt treatment of syphilis, and raise questions as to whether HIV-positive persons with certain chronic viral co-infections should initiate combined antiretroviral therapy at higher CD4 cell counts.

Rapid suppression of HIV-RNA is associated with improved control of immune activation in Mozambican adults initiating antiretroviral therapy with low CD4 counts.

Hide Abstract
The rapidity of HIV-RNA suppression after initiation of combined antiretroviral therapy (cART) may impact immune reconstitution in developing countries, where patients initiate cART at low CD4 T cell counts. One hundred and thirty-five HIV-1 Mozambican adults initiating cART were prospectively followed over 16 months within a larger observational study. Plasma HIV-RNA, CD4 counts, and CD8 T cell activation were monitored at the pre-cART visit and at 4, 10, and 16 months during cART. Of the 89 patients with available HIV-RNA data at pre-cART and 4 and 10 months post-cART, 68% (60/89) suppressed HIV-RNA at 4 months and were defined as "early virological controllers"(EC). Twenty of the 29 remaining patients who did not control HIV-RNA at 4 months did so at 10 months and were classified as "late virological controllers"(LC). Nine (10%) patients did not control HIV-RNA at either time point. Both initiating an EFV-containing cART regimen and having pre-cART tuberculosis were significantly associated with early HIV-RNA suppression if locked into a multivariate model [EFV OR: 13.6 (95% CI 1.7; 108.1) p = 0.014) tuberculosis OR: 11.0 (95% CI 1.4; 87.9) p = 0.024]. EC demonstrated significantly lower median activated CD8 T cells at 4, 10, and 16 months post-cART than did LC. Approximately 63% (12/19) of LC experienced reappearance of detectable HIV-RNA at 6 months postcontrol as compared to 15% (2/60) of EC (p = 0.001). This study suggests that rapid suppression of HIV-RNA may lead to a lower rate of reappearance of HIV-RNA, which could impact CD8 T cell activation levels in patients initiating cART at low CD4 counts.

Recent HIV-1 infection: identification of individuals with high viral load setpoint in a voluntary counselling and testing centre in rural Mozambique.
PLoS ONE
Show Abstract
Hide Abstract
Identification of recent HIV-infections is important for describing the HIV epidemic and compiling HIV-RNA-setpoint data for future HIV intervention trials. We conducted a study to characterize recent infections, and HIV-RNA-setpoint within the adult population presenting at a voluntary counselling and testing centre (VCT) in southern Mozambique.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
